    The diagnostic performance of canine serum amyloid A (SAA) was compared with that of C-reactive protein (CRP) in the detection of systemic inflammation in dogs. Sera from 500 dogs were retrospectively included in the study. C-reactive protein and SAA were measured using validated automated assays....... The overlap performance, clinical decision limits, overall diagnostic performance, correlations, and agreement in the clinical classification between these 2 diagnostic markers were compared. Significantly higher concentrations of both proteins were detected in dogs with systemic inflammation (SAA range: 48.......75 to > 2700 mg/L; CRP range: 0.4 to 907.4 mg/L) compared to dogs without systemic inflammation (SAA range: 1.06 to 56.4 mg/L; CRP range: 0.07 to 24.7 mg/L). Both proteins were shown to be sensitive and specific markers of systemic inflammation in dogs. Significant correlations and excellent diagnostic...

    A relationship between the expression of inflammation markers, oxidative stress and opium use has not been clearly established. This study was done to determine serum high-sensitivity C-reactive protein (hs-CRP), quantity of C3 and C4 complement factors, immunoglobulins, nitric oxide (NO) and total antioxidant capacity (TAC) in opium smokers and non-drug-using control participants. The present study was done on 44 male opium smokers and 44 controls of the same sex and age (20-40 years). The control group was healthy individuals with no lifetime history of drug abuse or dependence. All of the opium abusers were selected from those who had a history of opium use, for at least one year, with a daily opium dosage not less than 2g. Addicts known to abuse alcohol or other drugs were excluded. Serum hs-CRP concentration was measured using ELISA method and serum C3, C4 and immunoglobulins concentration were determined by Single Radial Immunodiffusion (SRID) method. NO production was estimated through Griess reaction and TAC was assessed by Ferric Reducing/Antioxidant Power (FRAP) test. Serum hs-CRP, complement factors (C3 and C4) and FRAP levels were significantly higher in the opium smokers (8.93 ± 1.93; 138.47 ± 13.39; 68.79 ± 7.02 and 972.75 ± 11.55, respectively) relative to the control group (0.72 ± 0.09; 93.36 ± 8.73; 33.08 ± 7.39 and 761.95 ± 18.61, respectively). These results permit us to conclude that opium smokers indeed present with a low to moderate grade inflammation, which is defined by an increase in acute phase proteins.

    Full Text Available Bacground/Aim. Preterm delivery is one of the most common complications in pregnancy, and it is the major cause (75- 80% of all neonatal deaths. Bacterial vaginosis predisposes to an increased risk of preterm delivery, premature rupture of membrane and miscarriage. In this syndrome normal vaginal lactobacilli, which produce protective H2O2, are reduced and replaced with anaerobic, gram-negative bacteria and others. The aim of this study was to evaluate the influence of bacterial vaginosis on the week of delivery and biochemical markers of inflammation in the serum. Methods. A total of 186 pregnant women were included into this study, between the week 16 and 19 of pregnancy. In the study group there were 76 pregnant women with diagnosed bacterial vaginosis by the criteria based on vaginal Gram-stain Nugent score and Amsel criteria. In the control group there were 110 healthy women with normal vaginal flora. Ultrasound examination was performed in both groups. Vaginal fluid and blood samples were taken to determine biochemical markers with colorimetric methods. Results. The week of delivery was statistically significantly shorter in the study group and the levels of biochemical markers of inflammation (C-reactive protein and fibrinogen in the serum were statistically significantly higher in women with bacterial vaginosis comparing to the control group. Also the levels of uric acid and white blood cells in the serum were higher in the study group compared to the control one. Conclusion. Our study indicates that the pregnancy complicated with bacterial vaginosis ends much earlier than the pregnancy without it. Also, higher levels of biochemical markers of inflammation in the serum in the study group, similarly to results of other studies, suggest that pathophysiological processes responsible for preterm delivery can begin very early in pregnancy.

    Hemodialysis patients are at greater risk of cardiovascular disease. Higher than expected cardiovascular morbidity and mortality in this population has been attributed to dislipidemia as well as inflammation. The causes of inflammation in hemodialysis patients are multifactorial. Several markers were used for the detection of inflammatory reaction in patients with chronic renal disease. These markers can be used for the prediction of future cardiovascular events. Among the several parameters of inflammatory markers, serum, CRP is well known and its advantages for the detection of inflammation and its predictor ability has been evaluated in several studies. This review addressed the associated factors and markers of inflammation in hemodialysis patients. In addition, their ability in predicting future atherosclerosis and effect of treatment has been reviewed. However, this context particularly in using CRP as a prediction marker of inflammation and morbidity requires further studies. PMID:24009946

    Objective Serum prostate-specific antigen (PSA) may be elevated in healthy men with systemic inflammation. We aimed to investigate the association between systemic inflammation markers and serum PSA in a healthy Korean population. Material and methods A cohort of 20,151 healthy native Korean men without prostate disease between the ages of 40 and 65 years who underwent medical checkups were studied from January 2007 to December 2013. Serum total PSA and serum C-reactive protein concentrations, neutrophil, lymphocyte, and platelet counts were determined. The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were calculated. We checked the correlation between systemic inflammation markers and PSA. Results Data obtained from 18,800 healthy men were analyzed. The mean age of the study subjects was 50.72±7.62 years and the mean NLR was 1.764±0.804. Correlation analysis after adjustment for age and body mass index (BMI) revealed that neutrophil count (coefficient = 0.028, p value <0.001), and NLR (coefficient = 0.027, p value <0.001) correlated with PSA. Multivariate analysis using the full model revealed that age, neutrophil count and NLR were positively correlated with PSA (p<0.001, 0.001, and 0.043 respectively). Multivariate analysis using a stepwise model revealed that age, neutrophil count and NLR were positively correlated with PSA (p<0.001, 0.001, and 0.040, respectively) and BMI was negatively correlated with PSA (p<0.001). Conclusion Systemic inflammation markers are useful with a serum PSA in a healthy Korean population. NLR in particular is significantly associated with serum PSA. PMID:28861299

    Rapid turnover proteins (RTPs), such as transthyretin (TTR), retinol binding protein (RBP), and transferrin (Tf), provide an accurate assessment of nutritional status but are susceptible to inflammation. Lipid-related markers, which have short half-lives in serum, may be better suited for nutritional assessment. We sought to identify sensitive nutritional markers unaffected by inflammation. Fasting serum samples were collected from 30 malnourished inpatients and 25 healthy volunteers. Malnourished inpatients were divided into 2 groups: a low-C-reactive protein (CRP) group (CRP group (CRP ≥ 20 mg/l, n = 15). Lipid-related markers, traditional nutritional markers, RTPs, micronutrients, and ketone bodies were measured and compared among the groups. Apolipoprotein (Apo)C-II and ApoC-III concentrations were lower in malnourished inpatients than in the control group. There was no significant difference in ApoC-II and ApoC-III between the low- and high-CRP groups. Carnitine transporters and ketone bodies did not show a significant difference among the three groups. Albumin, TTR, RBP, and Tf concentrations were lowest in the high-CRP group, intermediate in the low-CRP group, and highest in the control group. These results indicate that ApoC-II and ApoC-III are appropriate nutritional biomarkers unaffected by inflammation. Copyright © 2018 Elsevier B.V. All rights reserved.

    Sarcopenia is a geriatric syndrome characterized by the presence of low muscle mass and function. Possible mechanisms underlying sarcopenia include oxidative stress and elevation of inflammatory cytokines. The aim of the study was to evaluate the relationship between sarcopenia and biomarkers that may be involved in its pathogenesis and hence early detection. A total of 72 patients (36 sarcopenic and 36 non-sarcopenic) were included in the study. An experienced geriatric team applied comprehensive geriatric assessment to all patients. Anthropometric measures, gait speed and handgrip strength were recorded. Bioelectrical impedance analysis was used to assess skeletal muscle mass. In addition to routine clinical laboratory tests, serum adiponectin, thioredoxin-1 and pentraxin-3 levels were measured. Sarcopenia was defined according to the European Working Group on Sarcopenia in older Adults as the presence of low muscle mass and low muscle function or muscle performance. Sarcopenic patients were more likely to be functionally dependent and had lower scores on comprehensive geriatric assessment tools. Erythrocyte sedimentation rate (ESR) and C-reactive protein levels were significantly higher in the sarcopenic group. There was no significant difference in serum levels of thioredoxin-1 and pentraxin-3. Sarcopenic patients had lower levels of hemoglobin, albumin, total protein, calcium, triglycerides, uric acid and adiponectin (p sarcopenia whereas ESR was positively correlated. The present study demonstrated an association of sarcopenia with inflammatory markers CRP, ESR and adiponectin. Long-term prospective studies are warranted to confirm the relationship between markers oxidative stress and age related muscle decline.

    To explore the relationships between vitamin A, D and E and inflammation in relapsing remitting multiple sclerosis, we assessed their associations with 11 inflammation markers in 9 serial serum samples from 85 patients, before and during interferon-β1a treatment. A negative association was found between vitamin A and pentraxin 3 independent of interferon-β1a use, whereas positive associations between vitamin D and interleukin-1 receptor antagonist and secreted frizzled-related protein 3 were seen before, and between vitamin E and chemokine (C-X-C motif) ligand 16 during interferon-β1a treatment. These findings suggest associations with diverse inflammatory pathways, which may be differentially influenced by interferon-β1a treatment. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available ObjectiveTo investigate the simple serum markers for significant liver inflammation in chronic hepatitis B (CHB patients with an alanine aminotransferase (ALT level of <2 times upper limit of normal (ULN. MethodsThe clinical data of 278 CHB patients with ALT <2×ULN (ULN=40 U/L were analyzed retrospectively. Significant liver inflammation was defined as a liver inflammatory activity grade (G ≥2. The t-test was used for comparison of normally distributed continuous data between groups, and the Kruskal-Wallis rank sum test was used for non-normally distributed continuous data; the chi-square test was used for comparison of categorical data between groups. Multivariate logistic regression analysis was used to identify independent predictors for significant liver inflammation in CHB patients with ALT <2×ULN. The receiver operating characteristic (ROC curve was used to evaluate the diagnostic value of serum markers in significant liver inflammation. ResultsOf the 278 CHB patients enrolled, 175 (62.9% had no significant liver inflammation (G0-1 group and 103 (37.1% had significant liver inflammation (G2-4 group. There were significant differences in ALT, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase (GGT, albumin, globulin, prothrombin time (PT, platelet, absolute neutrophil count, hyaluronic acid (HA, glycocholic acid, precollagen Ⅲ, and collagen type Ⅳ(ⅣC between the two groups (all P<0.05. The multivariate regression analysis showed that GGT, PT, ⅣC, and HA were independent predictors for significant liver inflammation in CHB patients with ALT<2×ULN (OR=1.015, 1.600, 1.151, and 1.014, P=0.008, 0.021, 0.003, and 0.018. The areas under the ROC curve for GGT, PT, IVC, and HA to diagnose significant liver inflammation were 0.804, 0.722, 0.707, and 0.632, respectively. The cut-off value of 48.5 U/L for GGT to predict significant liver inflammation had a specificity of 90.3% and a negative

  11. Serum amyloid A is a marker for pulmonary involvement in systemic sclerosis.

    Full Text Available Inflammation in systemic sclerosis (SSc is a prominent, but incompletely characterized feature in early stages of the disease. The goal of these studies was to determine the circulating levels, clinical correlates and biological effects of the acute phase protein serum amyloid A (SAA, a marker of inflammation, in patients with SSc. Circulating levels of SAA were determined by multiplex assays in serum from 129 SSc patients and 98 healthy controls. Correlations between SAA levels and clinical and laboratory features of disease were analyzed. The effects of SAA on human pulmonary fibroblasts were studied ex vivo. Elevated levels of SAA were found in 25% of SSc patients, with the highest levels in those with early-stage disease and diffuse cutaneous involvement. Significant negative correlations of SAA were found with forced vital capacity and diffusion capacity for carbon monoxide. Patients with elevated SAA had greater dyspnea and more frequent interstitial lung disease, and had worse scores on patient-reported outcome measures. Incubation with recombinant SAA induced dose-dependent stimulation of IL-6 and IL-8 in normal lung fibroblasts in culture. Serum levels of the inflammatory marker SAA are elevated in patients with early diffuse cutaneous SSc, and correlate with pulmonary involvement. In lung fibroblasts, SAA acts as a direct stimulus for increased cytokine production. These findings suggest that systemic inflammation in SSc may be linked to lung involvement and SAA could serve as a potential biomarker for this complication.

    Increased intestinal permeability with subsequent metabolic endotoxemia, i.e., elevated circulating levels of bacterial lipopolysaccharide, LPS, has been introduced as a novel initiator of obesity related metabolic disturbances in non-pregnant individuals. The objective was to investigate the extent to which intestinal permeability, measured by serum zonulin concentration, is related to metabolic endotoxemia and metabolic risk markers in overweight pregnant women. This was a cross-sectional study including 100 pregnant overweight women in early pregnancy. Serum zonulin was analyzed using ELISA, and markers for metabolic endotoxemia (LPS), inflammation (high-sensitive C-reactive protein and glycoprotein acetylation GlyA), glucose metabolism (fasting glucose and insulin), and lipid metabolism were measured. Higher serum zonulin concentration associated positively with LPS (P=0.02), inflammatory markers (Pzonulin quartiles). All the observed associations were confirmed (Pzonulin concentration, i.e., increased intestinal permeability, contributes to metabolic endotoxemia, systemic inflammation, and insulin resistance in overweight pregnant women. By reinforcing intestinal barrier, it may be possible to manipulate maternal metabolism during pregnancy with subsequent health benefits. Copyright © 2017 Elsevier Inc. All rights reserved.

    We report on plasmonic photothermal therapy of rats with inoculated cholangiocarcinoma through the intratumoral injection of PEG-coated gold nanorods followed by CW laser light irradiation. The length and diameter of gold nanorods were 41+/-8 nm and 10+/-2 nm, respectively; the particle mass-volume concentration was 400 μg/mL, which corresponds to the optical density of 20 at the wavelength 808 nm. The tumor-bearing rats were randomly divided into three groups: (1) without any treatment (control); (2) with only laser irradiation of tumor; (3) with intratumoral administration of gold nanorods and laser irradiation of tumors. An hour before laser irradiation, the animals were injected intratumorally with gold nanorod solutions in the amount of 30% of the tumor volume. The infrared 808-nm laser with power density of 2.3 W/cm2 was used for plasmonic photothermal therapy (PTT). The withdraw of animals from the experiment was performed 24 h after laser exposure. The content of lipid peroxidation products and molecular markers of inflammation (TNF-α, IGF-1, VEGF-C) was determined by ELISA test in serum of rats. The standard histological techniques with hematoxylin and eosin staining were used for morphological examination of tumor tissues. It was revealed that the significant necrotic changes were noted in tumor tissue after plasmonic photothermal therapy, which were accompanied by formation of inflammatory reaction with release of proinflammatory cytokines and lipid peroxidation products into the bloodstream

    Evidence suggests that adipose tissue-derived adipokines induce mild inflammation and may play a role in insulin resistance associated with diabetes. The present study was designed to examine a series of adipokines and markers of inflammation in dogs before and after a successful weight loss. The study included fasting serum samples from twenty-five dogs before and after a weight-loss programme. Serum C-reactive protein (CRP) and monocyte chemoattractant protein-1 (MCP-1) were measured as indicators of chronic inflammation, while serum adipokines including total adiponectin, high-molecular-weight (HMW) adiponectin, resistin and leptin were also examined. Medians for CRP (before, 10.0 (interquartile range 5.4-15.0) μg/ml; after, 5.6 (interquartile range 3.8-7.0) μg/ml) and MCP-1 (before, 212 (interquartile range 157-288) ng/ml; after, 185 (interquartile range 143-215) ng/ml) decreased significantly after weight loss. Medians for resistin showed a mild, yet significant reduction (before, 67.1 (interquartile range 44.4-88.5) pg/ml; after, 60.5 (interquartile range 32.3-67.1) pg/ml), while leptin showed a dramatic decrease after weight loss (before, 18.9 (interquartile range 10.8-35.4) ng/ml; after, 6.6 (interquartile range 3.9-10.2) ng/ml). Serum total adiponectin and HMW adiponectin were unchanged on all analyses performed. These data suggest that weight loss can decrease chronic inflammation; however, the clinical implications of this decrease are not well elucidated in dogs. Surprisingly, there was no increase in total or HMW serum adiponectin after weight loss, as observed previously in human subjects. The lack of change in total and HMW adiponectin might explain why insulin resistance and type 2 diabetes are less prevalent in obese dogs when compared with humans and cats.

    Concentrations of persistent organic pollutants (POPs) are high in Inuit living predominately on the traditional marine diet. Adverse effects of POPs include disruption of the immune system and cardiovascular diseases that are frequent in Greenland Inuit. We aimed to assess the association between exposure to POPs from the marine diet and inflammation, taking into account other factors such as vitamin D. We invited Inuit and non-Inuit living in settlements or the town in rural East Greenland or in the capital city Nuuk. Participants completed a food frequency questionnaire and donated a blood sample for measurement of the two markers of inflammation YKL-40 and hsCRP, 25-hydroxy-vitamin D, eleven organochlorine pesticides (OCPs), fourteen polychlorinated biphenyls (PCBs), one polybrominated biphenyl, and nine polybrominated diphenyl ethers (PBDEs) adjusted to the serum lipid content. Participants were 50 through 69 years old, living in settlements, town or city (n = 151/173/211; 95% participation rate). ΣOCP, ΣPCB and ΣPBDE serum levels were higher in Inuit than in non-Inuit (pInuit compared to non-Inuit (pInuit diet and with markers of inflammation. This supports a pro-inflammatory role of POPs to promote chronic diseases common to populations in Greenland. These data inform guidelines on 'the Arctic dilemma' and encourage follow-up on the ageing Arctic populations.

    Full Text Available Objectives. Rheumatoid arthritis (RA is a systemic, inflammatory disease. Serum amyloid A (SAA is an acute-phase protein, involved in pathogenesis of atherosclerosis. The aim of the study was to assess serum concentration of SAA in RA patients, with reference to other inflammatory parameters and markers of extra-articular involvement. Methods. The study population consisted of 140 RA patients, low/moderate disease activity (L/MDA in 98 (70% patients and high disease activity (HDA in 42 (30%. Comprehensive clinical and laboratory assessment was performed with evaluation of electrocardiogram and carotid intima-media thickness. Results. The mean SAA concentration [327.0 (263.4 mg/L] was increased highly above the normal value, even in patients with L/MDA. Simultaneously, SAA was significantly higher in patients with HDA versus L/MDA. The mean SAA concentration was significantly higher in patients treated with glucocorticoids, was inversely associated with QTc duration, and was markedly higher in patients with atherosclerotic plaques, emphasizing increased CV risk. SAA was significantly higher in patients with increased cystatin-C level. Conclusions. In RA patients, high serum SAA concentration was strongly associated with activity of the disease and risk of CV and renal involvement. Recurrent assessment of SAA may facilitate searching patients with persistent inflammation and risk of extra-articular complications.

    Oxidative stress, inflammation and insulin resistance are the principal culprits in childhood obesity. Immune modifications are also important in the development of the obesity complications.The aim of this study is to find the relations for some immunity parameters with markers for oxidative stress and inflammation. Sixty obese children (10-16 years old) and thirty age and sex matched lean children were involved. The activities for erythrocyte superoxid dismutase (SOD), for erythrocyte glutathione peroxidase (GPx) and serum thioredoxin level were measured by ELISA, as oxidative stress markers. Circulating immune complexes (CIC), complement fractions C3, C4 and the self-antibodies, antismooth muscle antibodies (ASMA), antiliver-kidney microsome antibodies (LKM1) were measured by ELISA methods. Ceruloplasmin, haptoglobin and C reactive protein (CRP) were measured as inflammatory markers by immunoturbidimetric methods. ceruloplasmin (pLKM1 and ASMA and GPx activity were not modified between groups. Positive correlations (for pLKM1 (r=0.37), GPx activity and ASMA (r=0.27), haptoglobin and C3 (r=0.33), ceruloplasmin and CIC (r=0.41), CRP and C3 (p<0.27) and negative correlations were calculated for C4 both with GPx activity (r= -0.28) and with thioredoxin level (r= -0.27). In the obese children versus the lean ones, higher levels for C3 (p<0.001), C4(p<0.001), CIC (p<0.05), In conclusion, this study demonstrates that immune modifications, inflammation and oxidative stress are related and they act in cluster in childhood obesity.

    Serum prostate specific antigen (PSA) may be elevated in otherwise healthy men; systemic inflammation has been associated with cancer. The study of systemic inflammatory markers in men without clinical prostate disease, but with elevated PSA may characterize the subgroup of men at higher risk for subsequent prostate cancer. We investigated the associations between systemic inflammatory markers and serum PSA in 3,164 healthy men without prostatic disease, aged >40 years, from the 2001 to 2008 U.S. National Health and Nutrition Examination Survey (NHANES). Serum total PSA levels and concentrations of serum C-reactive protein (CRP) and plasma fibrinogen, neutrophil count, lymphocyte count, and platelet count were recorded. Neutrophil-lymphocyte ratio (NLR) ratio and platelet-lymphocyte (PLR) ratio were calculated. PSA elevation was defined as levels equal or greater than 4 ng/ml. Elevated serum PSA (194 men, 6.1% of the total), was significantly associated with plasma fibrinogen (ORmultiv  = 1.88; 95% CI, 1.09-3.25), and NLR (ORmultiv  = 1.14; 95% CI, 1.03-1.26), after adjustment for age, smoking, body mass index, education, race, co-morbidities, and use of medications. Markers of systemic inflammation were associated with elevated PSA in men without known prostatic disease. Future studies are needed to examine these markers' relationship with prostate cancer occurrence and progression. © 2014 Wiley Periodicals, Inc.

    Intestinal inflammation and increased intestinal permeability (both possibly fueled by dysbiosis) have been suggested to be implicated in the multifactorial pathogenesis of Parkinson's disease (PD). The objective of the current study was to investigate whether fecal markers of inflammation and impaired intestinal barrier function corroborate this pathogenic aspect of PD. In a case-control study, we quantitatively analyzed established fecal markers of intestinal inflammation (calprotectin and lactoferrin) and fecal markers of intestinal permeability (alpha-1-antitrypsin and zonulin) in PD patients (n = 34) and controls (n = 28, group-matched for age) by enzyme-linked immunosorbent assay. The study design controlled for potential confounding factors. Calprotectin, a fecal marker of intestinal inflammation, and two fecal markers of increased intestinal permeability (alpha-1-antitrypsin and zonulin) were significantly elevated in PD patients compared to age-matched controls. Lactoferrin, as a second fecal marker of intestinal inflammation, showed a non-significant trend towards elevated concentrations in PD patients. None of the four fecal markers correlated with disease severity, PD subtype, dopaminergic therapy, or presence of constipation. Fecal markers reflecting intestinal inflammation and increased intestinal permeability have been primarily investigated in inflammatory bowel disease so far. Our data indicate that calprotectin, alpha-1-antitrypsin and zonulin could be useful non-invasive markers in PD as well. Even though these markers are not disease-specific, they corroborate the hypothesis of an intestinal inflammation as contributing factor in the pathogenesis of PD. Further investigations are needed to determine whether calprotectin, alpha-1-antitrypsin and zonulin can be used to define PD subgroups and to monitor the effect of interventions in PD.

    Full Text Available BACKGROUND: Increased levels of pro-inflammatory factors, markers of oxidative stress and lipid profiles are known to be associated with several complications. The aim of this study was to determine the association of markers of systemic inflammation, oxidative stress and lipid profiles with insulin resistance in pregnant women in Kashan, Iran. METHODS: In a cross-sectional study, serum high sensitivity C-reactive protein (hs-CRP, tumor necrosis factor-alpha (TNF-α, fasting plasma glucose (FPG, serum insulin, 8-oxo-7, 8-dihydroguanine (8-oxo-G, total cholesterol, triglyceride, HDL-cholesterol, and plasma total antioxidant capacity (TAC were measured among 89 primigravida singleton pregnant women aged 18-30 years at 24-28 weeks of gestation. Pearson’s correlation and multiple linear regressions were used to assess their relationships with homeostatic model assessment of insulin resistance (HOMA-IR. RESULTS: We found that among biochemical indicators of pregnant women, serum hs-CRP and total cholesterol levels were positively correlated with HOMA-IR (β = 0.05, P = 0.006 for hs-CRP and β = 0.006, P = 0.006 for total cholesterol. These associations remained significant even after mutual effect of other biochemical indicators were controlled (β = 0.04, P = 0.01 for hs-CRP and β = 0.007, P = 0.02 for total cholesterol. Further adjustment for body mass index made the association of hs-CRP and HOMA-IR disappeared; however, the relationship for total cholesterol remained statistically significant. CONCLUSION: Our findings showed that serum total cholesterol is independently correlated with HOMA-IR score. Further studies are needed to confirm our findings.

    2012-03-01

    Full Text Available Abstract Osteosarcoma is the most common primary high-grade bone tumor in both adolescents and children. Early tumor detection is key to ensuring effective treatment. Serum marker discovery and validation for pediatric osteosarcoma has accelerated in recent years, coincident with an evolving understanding of molecules and their complex interactions, and the compelling need for improved pediatric osteosarcoma outcome measures in clinical trials. This review gives a short overview of serological markers for pediatric osteosarcoma, and highlights advances in pediatric osteosarcoma-related marker research within the past year. Studies in the past year involving serum markers in patients with pediatric osteosarcoma can be assigned to one of four categories, i.e., new approaches and new markers, exploratory studies in specialized disease subsets, large cross-sectional validation studies, and longitudinal studies, with and without an intervention. Most of the studies have examined the association of a serum marker with some aspect of the natural history of pediatric osteosarcoma. As illustrated by the many studies reviewed, several serum markers are emerging that show a credible association with disease modification. The expanding pool of informative osteosarcoma-related markers is expected to impact development of therapeutics for pediatric osteosarcoma positively and, it is hoped, ultimately clinical care. Combinations of serum markers of natural immunity, thyroid hormone homeostasis, and bone tumorigenesis may be undertaken together in patients with pediatric osteosarcoma. These serum markers in combination may do better. The potential effect of an intrinsic dynamic balance of tumor angiogenesis residing within a single hormone (tri-iodothyronine is an attractive concept for regulation of vascularization in pediatric osteosarcoma.

  10. Inflammation markers are associated with metabolic syndrome and ventricular arrhythmia in patients with coronary artery disease

    that CRP levels and WBC count were strongly related to components of the insulin resistance syndrome, such as BMI, waist circumference, insulin sensitivity, fasting insulin and proinsulin [26]. Elevated WBC levels have been associated with elevated serum triglyceride and cholesterol levels, fasting glucose levels, and diastolic blood pressure [13]. Leukocytosis is also associated with several disorders that characterize the metabolic syndrome and with micro- and macrovascular complications in patients with diabetes [41,42,56]. The association of AMPD1 34T allele with higher CRP observed in multivariate analysis should be treated with extreme caution, since it was not observed in the univariate analysis and it lost significance when BMI, LDL or HDL cholesterol was excluded from the multivariate model. Lack of a univariate association between C34T genotype and CRP in patients with past myocardial infarction was reported previously [1]. The multivariate relation observed in our study is not consistent with potential anti-inflammatory action of higher adenosine concentrations in 34T carriers [16]. This phenomenon may be related to the association between metabolic syndrome and C34T polymorphism. In our previous study we found that the polymorphism is associated with a reduced frequency of obesity in CAD patients and of hyperglycemia and diabetes in both CAD and heart failure patients [47]. Taken together, these results suggest that intercorrelations between inflammation, metabolic syndrome and the common functional AMPD1 polymorphism need further research. Our study revealed a strong association of the inflammation markers, particularly IL-6 and CRP, with past severe ventricular arrhythmia episodes. The strength of the association was similar to that of LVEDV, which is a potent marker of structural heart damage, with a proven prognostic role for the risk of cardiovascular events [21], and these factors were independent of each other in the multivariate model.

    Full Text Available Background and objective The detection of serum tumor markers is of great value for early diagnosis of lung cancer. The aim of this study is to summarize the clinic significance characteristics of serum markers contributing to the detection of lung cancer. Methods References about serum markers of lung cancer were estimated using meta-analysis method. 712 references which included more than 20 cases, 20 controls, the serum markers of 52 832 patients with malignancies and 32 037 patients as controls were evaluated. Results Overall the detection of 13 markers play a significant part in lung cancer diagnosis. The sensitivity of CEA, CA125, CYFRA21-1, TPA, SCCAg, DKK1, NSE, ProGRP in the patients’ serum with lung cancer were 47.50%, 50.11%, 57.00%, 50.93%, 49.00%, 69.50%, 39.73%, 51.48% and the specificity were 92.34%, 80.19%, 90.16%, 88.41%, 91.07%, 92.20%, 89.11%, 94.89%. In the combined analysis of tumor markers: the sensitivity, specificity of NSE+ProGRP were 88.90% and 72.82% in diagnosis of small cell lung cancer, respectively. In diagnosis of squamous corcinoma, the sensitivity and specificity of TSGF+SCCAg+CYFRA21-1 were 95.30% and 74.20%. The the sensitivity and specificity of CA153+Ferrtin+CEA were 91.90% and 44.00% in diagnosis of lung cancer. Conclusion Although the assay of tumor markers in serum is useful for diagnosis of early lung cancer, the sensitivity and specificity are low. Combined detection of these tumor markers could increase sensitivity and specificity.

    OBJECTIVES: To determine the serum and tissue levels of markers of impaired oxidative metabolism and correlate these levels with the histopathology and Alvarado score of acute appendicitis patients. METHOD: Sixty-five acute appendicitis patients (mean age, 31.4±12.06 years; male/female, 30/35) and 30 healthy control subjects were studied. The Alvarado score was recorded. Serum samples were obtained before surgery and 12 hours postoperatively to examine the total antioxidant status, total oxidant status, paraoxonase, stimulated paraoxonase, arylesterase, catalase, myeloperoxidase, ceruloplasmin, oxidative stress markers (advanced oxidized protein products and total thiol level) and ischemia-modified albumin. Surgical specimens were also evaluated. RESULTS: The diagnoses were acute appendicitis (n = 37), perforated appendicitis (n = 8), phlegmonous appendicitis (n = 12), perforated+phlegmonous appendicitis (n = 4), or no appendicitis (n = 4). The Alvarado score of the acute appendicitis group was significantly lower than that of the perforated+phlegmonous appendicitis group (p = 0.004). The serum total antioxidant status, total thiol level, advanced oxidized protein products, total oxidant status, catalase, arylesterase, and ischemia-modified albumin levels were significantly different between the acute appendicitis and control groups. There was no correlation between the pathological extent of acute appendicitis and the tissue levels of the markers; additionally, there was no correlation between the tissue and serum levels of any of the parameters. CONCLUSIONS: The imbalance of oxidant/antioxidant systems plays a role in the pathogenesis acute appendicitis. The Alvarado score can successfully predict the presence and extent of acute appendicitis. PMID:25518019

    Recent evidence has documented distinct effects of individual saturated FAs (SFAs) on cardiometabolic outcomes, with potential protective effects from odd- and very long-chain SFAs (VLSFAs). Cross-sectional and prospective associations of individual serum SFAs (12:0, 14:0, 15:0, 16:0, 18:0, 20:0, 22:0, and total SFA) with proinflammatory biomarkers and adiponectin were investigated in 555 adults from the IRAS. Principal component analysis (PCA) of proinflammatory markers yielded three clusters: principal component (PC) 1: fibrinogen, white cell count, C-reactive protein; PC 2: plasminogen activator inhibitor-1 (PAI-1), TNF-α, IL-18; PC 3: IL-6 and IL-8. Cross-sectional analyses on proinflammatory PCs and adiponectin, and prospective analyses on 5 year PAI-1 and fibrinogen concentrations were conducted with multiple regression. Total SFA and 16:0 were positively associated with PC 1 and PC 2, and negatively associated with adiponectin. The 14:0 was positively associated with PC 1 and negatively associated with adiponectin. In contrast, 15:0, 20:0, and 22:0 were negatively associated with PC 2, and 20:0 and 22:0 were positively associated with adiponectin. The 18:0 was negatively associated with PC 3. Prospectively, 15:0, 18:0, 20:0, and 22:0 were negatively associated with 5 year PAI-1 concentrations. The results demonstrate that individual SFAs have distinct roles in subclinical inflammation, highlighting the unique metabolic impacts of individual SFAs.

  14. Iron status and systemic inflammation, but not gut inflammation, strongly predict gender-specific concentrations of serum hepcidin in infants in rural Kenya.

    Directory of Open Access Journals (Sweden)

    Tanja Jaeggi

    Full Text Available Hepcidin regulation by competing stimuli such as infection and iron deficiency has not been studied in infants and it's yet unknown whether hepcidin regulatory pathways are fully functional in infants. In this cross-sectional study including 339 Kenyan infants aged 6.0±1.1 months (mean±SD, we assessed serum hepcidin-25, biomarkers of iron status and inflammation, and fecal calprotectin. Prevalence of inflammation, anemia, and iron deficiency was 31%, 71%, 26%, respectively. Geometric mean (±SD serum hepcidin was 6.0 (±3.4 ng/mL, and was significantly lower in males than females. Inflammation (C-reactive protein and interleukin-6 and iron status (serum ferritin, zinc protoporphyrin and soluble transferrin receptor were significant predictors of serum hepcidin, explaining nearly 60% of its variance. There were small, but significant differences in serum hepcidin comparing iron deficient anemic (IDA infants without inflammation to iron-deficient anemic infants with inflammation (1.2 (±4.9 vs. 3.4 (±4.9 ng/mL; P<0.001. Fecal calprotectin correlated with blood/mucus in the stool but not with hepcidin. Similarly, the gut-linked cytokines IL-12 and IL-17 did not correlate with hepcidin. We conclude that hepcidin regulatory pathways are already functional in infancy, but serum hepcidin alone may not clearly discriminate between iron-deficient anemic infants with and without infection. We propose gender-specific reference values for serum hepcidin in iron-replete infants without inflammation.

    C-reactive protein (CRP) is an established serum marker for the presence of systemic inflammation in dogs. Results from previous experimental and clinical studies suggest that CRP concentrations also quantitatively reflect the degree and progress of an inflammatory process, suggesting its use for inflammation monitoring. The objective was to investigate whether the canine CRP response in serum correlates with the amount of trauma and the consequent inflammatory response after 3 standard aseptic soft-tissue surgical procedures in 3 groups of dogs. A total of 24 client-owned intact female dogs of various breeds were enrolled in a clinical study with random allocation into 2 surgical groups, for either conventional, open-approach ovariohysterectomy (OVH; n = 14) or laparoscopic assisted OVH (n = 10). In addition, a group of 8 male Beagles from a laboratory animal facility underwent vasectomy, serving as the third and mildest surgical trauma group. Serum CRP was measured pre- and at 4, 8, 12, 23, and 27 hours postsurgery. Cumulative concentration over time and point concentrations of CRP were correlated with the surgical trauma impact level. There was a significant surgery trauma-related difference in cumulative CRP concentrations among the 3 groups, and also in the 12 hours postsurgery concentration. The CRP response varied according to the degree of surgical trauma on 3 standardized levels, thus supporting the use of canine serum concentrations of CRP as an inflammatory activity indicator and monitoring marker. © 2013 American Society for Veterinary Clinical Pathology.

    Faith Dickerson

    Full Text Available BACKGROUND: Markers of immune activation have been associated with mania but have not been examined in combination. We studied the association between mania and an inflammation score based on four immune markers. METHODS: A total of 57 individuals with mania were assessed at up to three time points: the day of hospital admission, evaluation several days later, and six-month follow-up. Also assessed were 207 non-psychiatric controls and 330 individuals with recent onset psychosis, multi-episode schizophrenia, or bipolar disorder depression. A combined inflammation score was calculated by factor analysis of the levels of class-specific antibodies to the NR peptide of the NMDA receptor; gliadin; Mason-Pfizer monkey virus protein 24; and Toxoplasma gondii. Inflammation scores among groups were compared by multivariate analyses. The inflammation score of the mania group at evaluation was studied as a predictor of re-hospitalization in the follow-up period. RESULTS: The combined inflammation score of the mania group at hospital admission and at evaluation differed significantly from that of the non-psychiatric controls (t=3.95, 4.10, p<.001. The inflammation score was significantly decreased at six month follow-up (F=5.85, p=0.004. There were not any significant differences in the inflammation scores of any of the other psychiatric groups and that of the controls. Within the mania group, an elevated inflammation score at evaluation predicted re-hospitalization (Hazard ratio=7.12, p=.005. CONCLUSIONS: Hospitalization for mania is associated with immune activation. The level of this activation is predictive of subsequent re-hospitalization. Interventions for the modulation of inflammation should be evaluated for the therapy of individuals with mania.

    Full Text Available Interleukin-(IL- 12 has been recently suggested to participate during development of insulin resistance in obese mice. Nevertheless, serum IL-12 levels have not been accurately determined in overweight and obese humans. We thus studied serum concentrations of IL-12 in Mexican adult individuals, examining their relationship with low-grade inflammation and obesity-related parameters. A total of 147 healthy individuals, 43 normal weight, 61 overweight, and 43 obese subjects participated in the study. Circulating levels of IL-12, tumor necrosis factor-alpha (TNF-α, leptin, insulin, glucose, total cholesterol, and triglyceride were measured after overnight fasting in all of the study subjects. Waist circumference and body fat percentage were recorded for all the participants. Serum IL-12 was significantly higher in overweight and obese individuals than in normal weight controls. Besides being strongly related with body mass index (r=0.5154, serum IL-12 exhibited a significant relationship with abdominal obesity (r=0.4481, body fat percentage (r=0.5625, serum glucose (r=0.3158, triglyceride (r=0.3714, and TNF-α (r=0.4717. Thus, serum levels of IL-12 are increased in overweight and obese individuals and show a strong relationship with markers of low-grade inflammation and obesity in the Mexican adult population. Further research is needed to understand the role of IL-12 in developing obesity-associated alterations in humans.

    Lung epithelial cells express surfactant protein D (SP-D), a calcium-dependent lectin that plays an important role in antibody-independent pulmonary host defense. Previous studies have shown that it is found in the peripheral circulation in patients with pulmonary disease, likely because of translocation into the blood when lung epithelial barriers are disrupted by inflammation or acute injury. In adults, serum SP-D levels are biomarkers for the progression and severity of chronic lung disease. In neonates, elevated SP-D levels in cord blood and on day 1 have been associated with prenatal risk factors and with an increased risk of respiratory distress syndrome and infections. It is not known whether serum SP-D during the first week of life is a marker for bronchopulmonary dysplasia (BPD), a form of chronic lung disease of prematurity that is associated with lung parenchymal maldevelopment and injury. The goal of this study is to determine whether serum SP-D on days 3 and 7 of life are associated with the development of BPD in preterm infants. Serum samples were obtained on postnatal days 3 and 7 from 106 preterm infants (500-2000 g birth weight, 23-32-week gestation). SP-D was quantified by Western blot. BPD was determined at 36 weeks PMA using NICHD criteria. The mean birth weight was 1145 ± 347 g and gestational age 29.2 ± 7.4 weeks. BPD was diagnosed in 7 and "BPD or death" in 16 infants. Days 3 and 7 values tracked significantly (r = 0.648), and did not correlate with birth weight or gestational age. Contrary to expectations, serum SP-D was not associated with BPD. Significant gender differences were noted, with SP-D dropping from day 3 to day 7 in males, while increasing in females (p D does not appear to be a useful marker for BPD. Decreasing serum SP-D levels in males, as compared to females, during the first week of life are likely related to gender differences in lung maturation, consistent with the higher incidence of BPD in males.

    Full Text Available Abstract Background Associations between ambient temperature and cardiovascular mortality are well established. This study investigated whether inflammation could be part of the mechanism leading to temperature-related cardiovascular deaths. Methods The study population consisted of a cohort of 673 men with mean age of 74.6 years, living in the greater Boston area. They were seen for examination roughly every 4 years, and blood samples for inflammation marker analyses were drawn in 2000-2008 (total of 1254 visits. We used a mixed effects model to estimate the associations between ambient temperature and a variety of inflammation markers (C-reactive protein, white blood cell count, soluble Vascular Cell Adhesion Molecule-1, soluble Intercellular Adhesion Molecule-1, tumor necrosis factor alpha, and interleukins -1β, -6 and -8. Random intercept for each subject and several possible confounders, including combustion-related air pollution and ozone, were used in the models. Results We found a 0 to 1 day lagged and up to 4 weeks cumulative responses in C-reactive protein in association with temperature. We observed a 24.9% increase [95% Confidence interval (CI: 7.36, 45.2] in C-reactive protein for a 5°C decrease in the 4 weeks' moving average of temperature. We observed similar associations also between temperature and soluble Intercellular Adhesion Molecule-1 (4.52%, 95% CI: 1.05, 8.10, over 4 weeks' moving average, and between temperature and soluble Vascular Cell Adhesion Molecule-1 (6.60%, 95% CI: 1.31, 12.2 over 4 weeks' moving average. Penalized spline models showed no deviation from linearity. There were no associations between temperature and other inflammation markers. Conclusions Cumulative exposure to decreased temperature is associated with an increase in inflammation marker levels among elderly men. This suggests that inflammation markers are part of intermediate processes, which may lead to cold-, but not heat-, related

    Diabetes is undoubtedly one of the most challenging health problems in 21st century. Understanding the pathogenesis and preventing long term complications have been major goals of research in diabetes mellitus (DM). Research in the past few years has linked oxidative stress and inflammation to beta cell dysfunction. Aim of this study is to evaluate serum gamma-glutamyl transferase (GGT) activity (marker of oxidative stress) and high sensitivity C reactive protein (hsCRP) level (an inflammatory marker) in type 2 DM subjects with good and poor glycemic control. Further, we investigated correlation between serum GGT and hsCRP level with glycemic control (FBS, PP2BS, HbA1c) in subjects. A cross sectional study consists of 150 patients out of them 50 patients having type 2 DM with good control (Group II), 50 patients with type 2 DM with poor control (Group III) and 50 normal healthy control (Group I) were selected. Serum GGT, serum hsCRP, FBS, PP2BS, HbA1c, and other biochemical investigations include serum liver enzymes and lipids were measured. Mean serum GGT and hsCRP concentration were statistically significantly higher in group III patients compared to group I and group II subjects as well as increased in group II compared to group I (p stress and inflammation appears to be a key component and also associated with poor glycemic control and further pathogenesis of diabetes and its complications. All our finding suggesting a link between oxidative stress, inflammation and glycemic control in patient with type 2 diabetes mellitus.

    Chemokines and cytokines are key signaling molecules that orchestrate the trafficking of immune cells, direct them to sites of tissue injury and inflammation and modulate their states of activation and effector cell function. We have measured, using a multiplex-based approach, the levels of 58 immune mediators and 7 acute phase markers in sera derived from of a cohort of patients diagnosed with acute Lyme disease and matched controls. This analysis identified a cytokine signature associated with the early stages of infection and allowed us to identify two subsets (mediator-high and mediator-low) of acute Lyme patients with distinct cytokine signatures that also differed significantly (pLyme disease (p = 0.01) and the decrease correlates with chemokine levels (p = 0.0375). The levels of CXCL9/10 did not relate to the size or number of skin lesions but elevated levels of serum CXCL9/CXCL10 were associated with elevated liver enzymes levels. Collectively these results indicate that the levels of serum chemokines and the levels of expression of their respective chemokine receptors on T cell subsets may prove to be informative biomarkers for Lyme disease and related to specific disease manifestations.

    Gastritis is an important premalignant lesion and recent studies suggested a production of inflammatory cytokine-like C-reactive protein during gastritis. This study aimed to determine any relationship between high sensitive C-reactive protein (hs-CRP) and inflammation activity among patients with gastritis. Demographic and clinical variables of participants were collected by a validated questionnaire. Using histology of the gastric mucosa, Helicobacter pylori status was investigated and serum concentrations of hs-CRP were measured among dyspeptic patients. Correlation between hs-CRP serum levels and inflammation activities was evaluated by logistic regression analysis. The relation between active inflammation and other variables was evaluated by logic link function model. Totally 239 patients (56.6% female) were analysed. The prevalence of mild, moderate and severe inflammation activities was 66.5%, 23.8% and 9.6% respectively. Mean ± SD of hs-CRP among men and women were 2.85 ± 2.84 mg/dl and 2.80 ± 4.80 mg/dl (p = 0.047) respectively. Mean ± SD of hs-CRP among patients with H. pylori infection, gland atrophy, metaplasia and dysplasia were 2.83 ± 3.80 mg/dl, 3.52 ± 5.1 mg/dl, 2.22 ± 2.3 mg/dl and 5.3 ± 5.04 mg/dl respectively. Relationship between hs-CRP and inflammation activities (p gastritis, elevated hs-CRP levels may be considered as a predictive marker of changes in gastric mucosa and a promising therapeutic target for patients with gastritis.

    Having noted an increased serum level of TPA and CEA in patients with renal carcinoma the authors extended these studies by using a larger number of tumor markers. In 15 patients (11 men and 4 women after menopause) aged 33 to 74 years who had renal carcinoma, among them 3 with tumor metastases, the serum concentration of TPA, CA 12-5, CEA, AFP, ferritin, prolactin, β-HCG, and β/sub 2/-microglobulin was measured by radioimmunoassay. Monoclonal antibodies were used in the determination of serum CA 12-5 and CEA. In all patients surgical treatment, irradiation, or cytostatic therapy had not been performed. In serum the normal range was exceeded by TPA in 7 patients, CA 12-5 in 3, CEA and AFP in one each, ferritin in 12, prolactin in 2, and β/sub 2/-microglobulin in 10 patients. In one man serum prolactin was reduced. Serum β-HCG was normal in all patients. According to these results serum ferritin, TPA, and β/sub 2/-microglobulin are of great value as tumor markers in patients with renal carcinoma. In several patients the increase of serum β/sub 2/-microglobulin may be ascribed partly to deterioration of renal function. As no consistent patterns of tumor markers in serum were observed it is recommended to determine several tumor markers and not only one of them during the follow-up of patients. Radioimmunoassays for measuring the serum level of tumor markers, especially ferritin, TPA, and β/sub 2/-microglobulin, may considerably assist in the management of patients with renal carcinoma by providing early information about tumor recurrence or metastases

    Previous research has reported associations between social relationships and carcinogenesis. Inflammation is a potential mediator of these associations. To clarify these links for one tumor site, we examined associations between social relationships, circulating inflammation markers, and breast cancer incidence. Among 132,262 participants from the prospective Women's Health Initiative, we used linear and logistic regression to evaluate associations between social relationship characteristics (social support, social strain, social network size) and inflammation markers of C-reactive protein (CRP) and white blood cell count (WBC). Cox regression was used to evaluate associations between inflammation markers and breast cancer incidence, as well as associations between social relationship characteristics and breast cancer incidence with and without adjustment for inflammation markers. Larger social networks were associated with lower continuous CRP (beta = -0.22, 95% CI -0.36, -0.08) and WBC (beta = -0.23, 95% CI -0.31, -0.16). Greater social strain was associated with higher continuous CRP (beta = 0.24, 95% CI 0.14, 0.33) and WBC (beta = 0.09, 95% CI 0.04, 0.14). When WBC was dichotomized at 10,000 cells/uL, high WBC was associated with greater hazards of in situ breast cancer (HR = 1.65, 95% CI 1.17, 2.33) but not invasive breast cancer. Social relationship characteristics were not associated with incidence of invasive or in situ breast cancer. Larger social networks were associated with lower inflammation and greater social strain was associated with higher inflammation. Higher inflammation might be associated with development of in situ breast cancer, but this appeared to be due to factors other than social relationships. Copyright © 2018 Elsevier Ltd.

    Increased levels of pro-inflammatory factors, markers of oxidative stress and lipid profiles are known to be associated with several complications. The aim of this study was to determine the association of markers of systemic inflammation, oxidative stress and lipid profiles with insulin resistance in pregnant women in Kashan, Iran. In a cross-sectional study, serum high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-alpha (TNF-α), fasting plasma glucose (FPG), serum insulin, 8-oxo-7, 8-dihydroguanine (8-oxo-G), total cholesterol, triglyceride, High density lipoprotein-cholesterol (HDL-cholesterol), and plasma total antioxidant capacity (TAC) were measured among 89 primigravida singleton pregnant women aged 18-30 years at 24-28 weeks of gestation. Pearson's correlation and multiple linear regressions were used to assess their relationships with homeostatic model assessment of insulin resistance (HOMA-IR). We found that among biochemical indicators of pregnant women, serum hs-CRP and total cholesterol levels were positively correlated with HOMA-IR (β = 0.05, P = 0.006 for hs-CRP and β = 0.006, P = 0.006 for total cholesterol). These associations remained significant even after mutual effect of other biochemical indicators were controlled (β = 0.04, P = 0.01 for hs-CRP and β = 0.007, P = 0.02 for total cholesterol). Further adjustment for body mass index made the association of hs-CRP and HOMA-IR disappeared; however, the relationship for total cholesterol remained statistically significant. Our findings showed that serum total cholesterol is independently correlated with HOMA-IR score. Further studies are needed to confirm our findings.

    Full Text Available Chronic inflammation contributes to the onset and development of metabolic diseases. Clinical evidence has suggested that coenzyme Q10 (CoQ10 has some effects on inflammatory markers. However, these results are equivocal. The aim of this systematic review was to assess the effects of CoQ10 on serum levels of inflammatory markers in people with metabolic diseases.Electronic databases were searched up to February 2016 for randomized controlled trials (RCTs. The outcome parameters were related to inflammatory factors, including interleukin-6 (IL-6, tumor necrosis factor-alpha (TNF-α and C reactive protein (CRP. RevMan software was used for meta-analysis. Meta-regression analysis, Egger line regression test and Begg rank correlation test were performed by STATA software.Nine trials involving 428 subjects were included in this meta-analysis. The results showed that compared with control group, CoQ10 supplementation has significantly improved the serum level of CoQ10 by 1.17μg/ml [MD = 1.17, 95% CI (0.47 to 1.87 μg/ml, I2 = 94%]. Meanwhile, it has significantly decreased TNF-α by 0.45 pg/ml [MD = -0.45, 95% CI (-0.67 to -0.24 pg/ml, I2 = 0%]. No significant difference was observed between CoQ10 and placebo with regard to CRP [MD = -0.21, 95% CI (-0.60 to 0.17 mg/L, I2 = 21%] and IL-6 [MD = -0.89, 95% CI (-1.95 to 0.16 pg/ml, I2 = 84%].CoQ10 supplementation may partly improve the process of inflammatory state. The effects of CoQ10 on inflammation should be further investigated by conducting larger sample size and well-defined trials of long enough duration.

    Full Text Available Type-2/eosinophilic inflammation plays a pivotal role in asthma. The identification of severe type-2/eosinophilic asthma is important for improving the management of patients with asthma. Therefore, efforts to develop non-invasive biomarkers for type-2/eosinophilic airway inflammation have been made during this decade. Currently, fraction of exhaled nitric oxide (FeNO and serum periostin levels are considered markers of type-2/eosinophilic inflammation in asthma. However, a single-marker approach has limited the ability to diagnose severe type-2/eosinophilic asthma accurately and predict disease outcomes precisely. The present article reviews the utility of FeNO and serum periostin levels in a single-marker approach and in a multiple-marker approach in identifying patients with severe type-2/eosinophilic asthma. Furthermore, based on a sub-analysis of the Kinki Hokuriku Airway disease Conference (KiHAC, geno-endo-phenotypes of patients were stratified into four groups according to the FeNO and serum periostin levels.

    Fetuin-A levels are reported to be low as a negative acute phase reactant in systemical inflammatory situations. Hashimoto thyroiditis is characterized with inflammation. In this study, we hypothesised that the serum fetuin A levels could be found to be low due to inflammation in patients with Hashimoto thyroiditis. For this purpose, serum fetuin A levels in patients with Hashimoto thyroiditis were compared with those in healthy subjects. A total of 85 participants (11 male, 74 female, mean age: 38.60±10.14 years) were included. The patient group consisted of 44 Hashimoto thyroiditis patients with subclinical hypothyroidism (7 male, 37 female) and the control group consisted of 41 healthy subjects (4 male, 37 female). Groups were compared according to their demographic, anthropometric and biochemical data and serum fetuin-A levels. Correlation analysis was used for determining the relation between fetuin A levels and clinical parameters. Fetuin-A levels of the patient group were found lower than those of the control group (0.58±0.50 g/L versus 1.53±1.60 g/L, P=0.001). Fetuin-A levels were not correlated with clinical parameters such as TSH, C-reactive protein, body mass index, waist circumference, blood pressure, glucose, and lipids. These findings supported the hypothesis that serum fetuin A levels could be found to be low as a negative acute phase reactant in patients with Hashimoto thyroiditis. Fetuin A can be considered as an indicator of inflammation in Hashimoto thyroiditis.

    2016-09-01

    Full Text Available Background: Insulin resistance, which is associated with an increased risk of cardiovascular morbidity and mortality, has become a leading nutrition problem. Inorganic nitrate enriched in spinach has been demonstrated to reverse the pathological features of insulin resistance and endothelial dysfunction. However, the effects of a direct intake of nitrate-enriched spinach on insulin resistance and endothelial dysfunction have not been studied. Objective: To investigate the effects of spinach nitrate on insulin resistance, lipid metabolism, endothelial function, and inflammation in mice fed with a high-fat and high-fructose diet. Design: A diet intervention of spinach with or without nitrate was performed in mice. A high-fat and high-fructose diet was used to cause insulin resistance, endothelial dysfunction, and inflammation in mice. The impacts of spinach nitrate on lipid profile, insulin resistance, markers of endothelial function, and inflammation were determined in mice. Results: Spinach nitrate improved the vascular endothelial function of the mice with high-fat and high-fructose consumption, as evidenced by the elevated plasma nitrite level, increased serum nitric oxide (NO level and decreased serum ET-1 level after spinach nitrate intervention. Spinach nitrate also reduced serum triglycerides, total cholesterol, and low-density lipoprotein-cholesterol levels and elevated serum high-density lipoprotein-cholesterol levels in the mice fed with a high-fat and high-fructose diet. Mice receiving spinach with 60 mg/kg of nitrate (1.02±0.34 showed a significantly low homeostasis model assessment-insulin resistance index as compared with the model mice (2.05±0.58, which is indicating that spinach nitrate could effectively improve the insulin resistance. In addition, spinach nitrate remarkably decreased the elevated serum C-reactive protein, tumor necrosis factor α, and interleukin-6 levels induced by a high-fat and high-fructose diet

    Full Text Available Introduction. Prevalence of bowel diseases in children is the second, trailing only the diseases of gastroduodenal zone and growing in recent years. Actual one is the problem of differential diagnosis of functional and inflammatory intestinal diseases using non-invasive methods on the prehospital stage and as a screening. Objective. Comparative analysis of fecal markers of the bowel inflammation (lactoferrine and calprotectine with endoscopy and morphology of intestinal mucosa in children. Matherials and methods. 49 children aged 6–18 years were examined. All patients underwent endoscopic and morphological study of the intestine, coprotest, determination of fecal markers of bowel inflammation (lactoferrin and calprotectine. Results. It is shown that in young children, the intestinal mucosa mainly hadn’t endoscopic changes, coprotest and morphological examination didn’t reveal the signs of inflammation, fecal intestinal inflammation markers were negative (p < 0.05. In the group of older children, moderate or marked catarrhal changes were found endoscopically, coprotest results were typical of inflammation in the intestines, it was morphologically proved the presence of chronic inflammation of the mucous membrane of the colon with signs of atrophy, the results of lactoferrin and calprotectine determination were positive (p < 0.05. Conclusion. The findings suggest that the evaluation of calprotectine and lactoferrin can be used in pediatric patients because of its non-invasiveness as diagnostic screening for the selection of patients for the further endoscopic examination and diagnostic search.

    Background Common variable immunodeficiency is a rare clinically symptomatic primary immunodeficiency disorder which manifests a wide variability of symptoms, complications. Atherosclerosis in common variable immunodeficiency patients has not been investigated yet contrary to other severe clinical complications. We aimed to investigate the chitotriosidase enzyme's role as an inflammation and atherosclerosis marker in paediatric common variable immunodeficiency patients. Methods Common variable immunodeficiency patients (n = 24) and healthy controls (n = 23) evaluated for chitotriosidase activity with other inflammation markers (hsCRP, myeloperoxidase, serum amyloid A, ferritin), lipid profile and echocardiographic findings (carotid artery intima media thickness - cIMT, brachial artery flow-mediated vazodilatation - FMD%). Results In patients, the mean chitotriosidase activity (8.98 ± 6.28) was significantly higher than the controls (5.17 ± 3.42) ( P = 0.014). Chitotriosidase showed positive relation with hs-CRP ( P = 0.011) and SAA ( P = 0.011) but had no relation with ferritin ( P = 0.155), HDL ( P = 0.152) or LDL-cholesterol ( P = 0.380). Mean cIMT increased in patients compared with the controls ( P variable immunodeficiency patients demonstrated in vivo the presence of activated macrophages indicating ongoing inflammation. Echocardiographic diastolic functional deficiency, increased cIMT and decreased FMD% may be accepted as early atherosclerotic findings, but none of them showed relationship with chitotriosidase activities.

    Obesity is increasing in prevalence worldwide and has emerged as a strong risk factor for periodontal disease. Conversely, the remote effects of periodontal disease on various systemic diseases have been proposed. The aim of this study is to determine the presence of MCP-4 and high sensitivity C reactive protein (hsCRP) levels in gingival crevicular fluid (GCF) and serum in obese and non-obese subjects with chronic periodontitis and to find a correlation between MCP-4 and hsCRP in GCF and serum. Forty subjects (20 males and 20 females) were selected and divided into four groups (10 subjects in each group), based on clinical parameters: group NOH (non-obese healthy), group OH (obese healthy), Group NOCP (non-obese with chronic periodontitis) and group OCP (obese with chronic periodontitis). The levels of serum and GCF MCP-4 were determined by ELISA and hsCRP levels were determined by immunoturbidimetry method. The mean GCF and serum concentration of MCP-4 was highest for group OCP followed by group NOCP, group OH (in GCF); group OH, group NOCP(in serum) and least in group NOH. The mean hsCRP concentration was highest for group OCP followed by group OH, group NOCP and group NOH. A significant positive correlation was found between serum and GCF MCP-4 and hsCRP levels. GCF MCP-4 concentrations increased in periodontal disease compared to health and correlated positively with the severity of disease indicating it as a novel marker of periodontal disease. The serum concentration of MCP-4 was found to be more in obese group as compared to nonobese group indicating it as a marker of obesity. Furthermore, based on the positive correlation of MCP-4 and hsCRP found in this study, it can be proposed that MCP-4 and hsCRP may be the markers linking chronic inflammation in obesity and periodontal disease.

    Chronic cadmium exposure may cause disease through induction of systemic oxidative stress and inflammation. Factors that mitigate cadmium toxicity and could serve as interventions in exposed populations have not been well characterized. We used data from the 2003–2010 National Health and Nutrition Examination Survey to quantify diet's role in modifying associations between cadmium exposure and oxidative stress and inflammation. We created a composite antioxidant and anti-inflammatory diet score (ADS) by ranking participants by quintile of intake across a panel of 19 nutrients. We identified associations and effect modification between ADS, urinary cadmium, and markers of oxidative stress and inflammation by multiple linear regression. An interquartile range increase in urinary cadmium was associated with a 47.5%, 8.8%, and 3.7% increase in C-reactive protein (CRP), gamma glutamyl transferase (GGT), and alkaline phosphatase (ALP), respectively. An interquartile range increase in ADS was associated with an 7.4%, 3.3%, 5.2%, and 2.5% decrease in CRP, GGT, ALP, and total white blood cell count respectively, and a 3.0% increase in serum bilirubin. ADS significantly attenuated the association between cadmium exposure, CRP and ALP. Dietary interventions may provide a route to reduce the impact of cadmium toxicity on the population level. - Highlights: • Cadmium may cause chronic disease through oxidative stress or inflammation. • We developed a score to quantify dietary antioxidant and anti-inflammatory intake. • Cadmium was associated with markers of oxidative stress and inflammation. • Antioxidant and anti-inflammatory intake mitigated the effects of cadmium exposure. • Dietary interventions may be effective against chronic cadmium toxicity.

    To determine the serum hyaluronic acid (HA) levels as biochemical marker of hepatic fibrosis and cirrhosis and correlate it with the degree of hepatic fibrosis and cirrhosis. This study was performed on 100 patients of chronic liver disease whose liver biopsies had been carried out. Fifty healthy controls were also included in the study. Routine liver function tests, hepatitis serology and serum hyaluronic acid levels were carried out on patients and controls. Liver biopsy of 100 patients revealed that 21 were in stage 0 fibrosis, 38 in stage 1 fibrosis, 26 in stage 3 fibrosis and 15 in stage 4 fibrosis. Mean Serum HA (mean +- SD) concentration in patients were 189 +- 98 mg/L vs. 21 +- 10 mg/L of healthy controls. The difference observed was statistically significant (p < 0.001). Patients in stage 4 fibrosis had significantly higher (p <0.001) mean serum HA concentration as compared to other stages of liver fibrosis. Diagnostic accuracy of serum HA at marginally elevated level of 60 mg/L determined the sensitivity 78.4 %, specificity 80.9%, positive predicted value 93.9% and negative predicted value of 50%. Serum HA is a useful non-invasive marker of liver fibrosis. There is a strong positive correlation between serum HA levels and degree of liver fibrosis. The concentration of serum HA rises according to progression of liver fibrosis and levels are highest in patients with liver cirrhosis. (author)

    The aim of this study was to examine endothelial dysfunction and inflammation in hypertension and prediabetes by studying adhesion molecules and inflammatory factors. This study included 133 outpatients. Participants were categorized into three groups based on the presence or absence of hypertension and prediabetes: control subjects without prediabetes and hypertension (N group, n = 39); patients with hypertension only (H group, n = 34); and patients with hypertension and prediabetes (HD group, n = 60). Hypertension was diagnosed according to JNC7 criteria. Prediabetes was defined according to 2010 American Diabetes Association criteria. Plasma was isolated from overnight fasting blood samples for enzyme-linked immunosorbent assay (ELISA) analysis of concentrations of intercellular adhesion molecule-1 (ICAM-1), tumor necrosis factor-α (TNF-α), P-selectin, and interleukin-6 (IL-6) as indicators of endothelial function and inflammation. We found that the H and HD groups showed significantly higher levels of all four biomarkers compared with the N group (all p Prediabetes and hypertension induce endothelial dysfunction and inflammation by elevating levels of soluble adhesion molecules and inflammatory cytokines. The comorbidity of these diseases may exacerbate inflammation and endothelial dysfunction by enhancing the expression of ICAM-1 and TNF-α.

    Full Text Available The detection of serum tumor markers is valuable for the early diagnosis of lung cancer. Tumor markers are frequently used for the management of cancer patients. However, single markers are less efficient but marker combinations increase the cost, which is troublesome for clinics. To find an optimal serum marker combination panel that benefits the patients and the medical management system as well, four routine lung cancer serum markers (SCCA, NSE, CEA, and CYFRA21-1 were evaluated individually and in combination. Meanwhile, the costs and effects of these markers in clinical practice in China were assessed by cost-effectiveness analysis. As expected, combinations of these tumor markers improved their sensitivity for lung cancer and different combination panels had their own usefulness. NSE + CEA + CYFRA21-1 was the optimal combination panel with highest Youden’s index (0.64, higher sensitivity (75.76%, and specificity (88.57%, which can aid the clinical diagnosis of lung cancer. Nevertheless, the most cost-effective combination was SCCA + CEA, which can be used to screen the high-risk group.

    Duchenne Muscular Dystrophy (DMD) is the most frequent dystrophy in childhood generated by a deficiency in dystrophin. DMD is a neuromuscular disease and its clinical course comprises chronic inflammation and gradual muscle weakness. Supplementation of omega-3 long chain-Polyunsaturated Fatty Acids (ω-3 long chain-PUFA) reduces inflammatory markers in various disorders. The goal of this research was to analyze the influence of ω-3 long chain-PUFA intake on gene expression and blood inflammatory markers in boys with DMD. In a placebo-controlled, double. Blind, randomized trial, boys with DMD (n = 36) consumed 2.9 g/day of ω-3 long chain-PUFA or sunflower oil as control, in capsules, for a period of 6 months. Blood was analyzed at baseline and at months 1, 2, 3, and 6 of supplementation for expression of inflammatory markers in leukocytes and serum. There was high adherence to capsule intake (control: 95.3% ± 7.2%, and ω-3 long chain-PUFA: 97.4% ± 3.7% at month 6). Enrichment of EicosaPentaenoic Acid (EPA) and DocosaHexaenoic Acid (DHA) in erythrocytes increased significantly in patients supplemented with ω-3 long chain-PUFA compared with the placebo group during the 6 months of supplementation. Messenger RNA (mRNA) of the Nuclear Factor kappa beta (NF-κB) and its target genes InterLeukin 1 beta (IL-1β) and IL-6 was downregulated significantly (p Omega-3 long chain-PUFA intake decreased the serum IL-1β (-59.5%; p = 0.011) and IL-6 (-54.8%; p = 0.041), and increased the serum IL-10 (99.9%, p < 0.005), in relation to those with placebo treatment. Supplementation with ω-3 long chain-PUFA 2.9 g/day is well-tolerated, has a beneficial reductive effect on proinflammatory markers, and increases an anti-inflammatory marker, indicating that ω-3 long chain-PUFA could have a potential therapeutic impact on chronic inflammation in DMD.

    As in human populations, advances in nutrition and veterinary care have led to an increase in the lifespan of companion animals. Detrimental physiological changes occurring later in life must be understood before interventions can be made to slow or reduce them. One important aspect of human aging is upregulation of the inflammatory response and increase in oxidative damage resulting in pathologies linked to chronic inflammation. To determine whether similar processes occur in the aging dog, changes in markers of inflammation and oxidative stress were investigated in 80 Labrador retrievers from adulthood to the end of life. Serum levels of immunoglobulin M (p immunoglobulin G or C-reactive protein unless the last year of life was included in the analysis (p = .002). Baseline levels of heat shock protein 70 decreased with age (p < .001) while those after exposure to heat stress were maintained (p = .018). However, when excluding final year of life data, a decline in the heat shock protein 70 response after heat stress was observed (p = .004). These findings indicate that aging dogs undergo changes similar to human inflammaging and offer the possibility of nutritional or pharmacological intervention to delay or reduce these effects.

    Increased permeability of the intestinal wall and intestinal dysbiosis may contribute to chronic systemic inflammation, one of the causes of accelerated atherosclerosis and cardiovascular morbidity and mortality burden in patients with chronic kidney disease. The aim of this study was to evaluate the association between markers of intestinal permeability and inflammation in haemodialysis (HD) patients. Plasma concentration of zonulin, haptoglobin, TNFα, IL6, D-lactates and bacterial lipopolysaccharides (LPS) was assessed in blood samples obtained after overnight fast before midweek morning HD session in 150 stable, prevalent HD patients. Daily intake of energy and macronutrients was assessed on the basis of a food frequency questionnaire. Serum hsCRP level was increased in over 70% of patients. Plasma levels of zonulin [11.6 (10.9-12.3) vs 6.8 (5.8-7.8) ng/mL], IL6 [6.2 (1.0-10.3) vs 1.3 (1.0-2.0) pg/mL] and TNFα [5.9 (2.9-11.8) vs 1.6 (1.3-1.8) pg/mL], but not LPS and D-lactates were significantly higher in HD than in healthy controls. D-lactates and LPS levels were weakly associated with IL6 (R = 0.175; p = 0.03, and R = 0.241; p = 0.003). There was a borderline correlation between plasma zonulin and serum hsCRP (R = 0.159; p = 0.07), but not with IL6, LPS and D-lactates. In multiple regression, both serum CRP and plasma IL6 variability were explained by LPS (β = 0.143; p = 0.08 and β = 0.171; p = 0.04, respectively), only. The weak association between plasma D-lactate, LPS and IL6 levels indicates that intestinal flora overgrowth or increased intestinal permeability contributes very slightly to the chronic inflammation development in HD patients.

    Full Text Available Aims: Resistin is an adipocytokine, which have been studied for its role in insulin resistance and recently in inflammation. The aim of the present study is to assess the concentration of resistin in serum and gingival crevicular fluid (GCF and to compare the levels between subjects with and without periodontitis and type 2 diabetes mellitus (T2DM and to further correlate the resistin levels with the single-nucleotide polymorphism (SNP at −420. Setting and Designs: A total of 96 subjects (48 males and 48 females were divided on the basis of gingival index (GI, probing pocket depth (PD, clinical attachment level (CAL and hemoglobin A 1c levels into healthy (group 1, n = 24, uncontrolled-diabetes related periodontitis (group 2, n = 24, controlled-diabetes related periodontitis (group 3, n = 24 and chronic periodontitis without T2DM (group 4, n = 24. Materials and Methods: The GCF and serum levels of resistin were quantified using the enzyme-linked immunosorbent assay and compared among the study groups. Further, the association of the resistin levels with periodontal inflammation and SNP at −420 was studied. Results and Conclusion: The resistin levels in GCF and serum from patients with periodontitis or diabetes mellitus related periodontitis (controlled or uncontrolled were higher than that of healthy subjects and correlated positively with GI. Further, subjects with GG genotype at −420 showed significantly higher GI, PD, CAL as compared with genotype group CC. Resistin was detected in all serum and GCF samples and was significantly higher in periodontitis. Further, GG genotype at −420 was associated significantly with periodontal inflammation and resistin levels.

    The tumor marker CA-125 is an embrional glycoprotein detectable in tissues derived from celomatic epitelium. Serum Ca-125 was determined by RIA in 66 patients with various ovarian pathologies (16 malignant at stage III-IV and 50 benign). Six patients with ovarian carcinoma were monitored during the first week after surgery and chemiotherapy for a total of 150 days of treatment. It has been observed that CA-125 serum level is consistently above the normal range (>35 U/ml) in all malignant diseases. In benign pathology, levels above the normal were found to be represented almost exclusively by ovarian endometriosis. Furthermore, the results demonstrate that chemiotherapy alone is capable of lowering CA-125 serum levels. This tumor marker may be of great advantage in diagnosis and follow-up of ovarian malignancy

    Iron overload is an increasingly recognized phenomenon in nonhemochromatosis cirrhosis. To evaluate the relationship between iron overload and liver insufficiency and portal hypertension. Cirrhotics with hepatic hemodynamic and ferritin measurement (within 30 d) were included. Exclusion criteria were malignancy (except hepatocellular carcinoma Milan-in), severe chronic obstructive pulmonary disease, acute events in the previous 2 weeks, immunosuppression, transjugular intrahepatic portosystemic shunt or portal vein thrombosis, and end-stage renal disease. Patients were followed-up until death or liver transplant. Univariate and multivariate analysis were used. Fifty-one patients were included (male 61%; median age 57 y; interquartile range, 47 to 66 y); Child-Pugh A 11/B 25/C 15). A positive correlation was observed between ferritin and markers of inflammation (C-reactive protein: r=0.273, P=0.06 and aspartate aminotransferase: r=0.302, P=0.035). No correlation between ferritin and hepatic venous pressure gradient was seen. Negative correlations were observed between ferritin and circulatory dysfunction (mean arterial pressure: r=-0.360, P=0.014 and serum sodium: r=-0.419, P=0.002). In contrast, associations to markers of liver failure such as international normalized ratio (r=0.333, P=0.005), bilirubin (r=0.378, P=0.007), albumin (r=-0.265, P=0.082), model for end-stage liver disease (r=0.293, P=0.041), and Child-Pugh score (r=0.392, P=0.009) were observed. No differences in survival according to ferritin was detected. In patients with cirrhosis, serum ferritin levels are associated with markers of liver insufficiency, inflammation, and circulatory dysfunction but not portal hypertension.

    Full Text Available Background/Aim. Immune system disorder, including inflammation, takes a significant place when considering still unclear etiology of schizophrenia. The aim of this study was to determine the blood levels of nonspecific inflammation markers in the first episode of schizophrenia and their relation to the therapy response. Methods. In this study we determined the blood levels of nonspecific inflammation markers: white blood cells count (WBC, C-reactive protein (CRP, erythrocytes sedimentation rate (ESR and the elements of differential white blood cell counts (or the leukocyte formula: granulocytes (Gra, lymphocytes (Lym and monocytes (Mon, in the first episode of schizofrenia, in 78 patients hospitalized at the Clinic for Psychiatric Disorders “Dr Laza Lazarević” in Belgrade. The levels were measured at admission to the clinic, as well as after 4 weeks of antipsychotic treatment. The Positive and negative syndrome scale for schizophrenia (PANSS was applied to measure the severity of psychopathology and response to the treatment. Results. During the first episode of schizophrenia, before initiation of antipsychotic treatment, the frequency of abnormal values was high (≥ 25% of the patients for the following non-specific inflammation markers: WBC, CRP, ESR and Gra, in the leukocyte formula, but dropped after 4 weeks of antipsychotic treatment at the level of high statistical significance for WBC and Gra (p < 0.001. The ESR remained unchanged in as many as 50% of the patients even after 4-week antipsychotic treatment, at the level of statistical significance in the non-responders compared to the responders (p = 0.045. Conclusion. The obtained results indicate that in the first episode of schizophrenia the blood levels of non-specific inflammation markers (WBS, CRP, ESR and Gra from the leukocyte formula were high in the subpopulation of patients with the tendency towards normalization of inflammation parameters after a 4-week antipsychotic

    Psoriasis has been considered as systemic disorder. Lipocalin-2 might be a link between psoriasis and its comorbidities. Aim of the study was to investigate the associations between serum lipocalin-2 levels and the disease activity, markers of inflammation or metabolic disturbances and changes after topical treatment in psoriatic patients. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were recruited. Blood samples were collected before and after 14 days of therapy. Serum lipocalin-2 concentrations were examined by enzyme-linked immunosorbent assay. The results were correlated with Psoriasis Area and Severity Index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and with effectiveness of topical treatment. Lipocalin-2 serum levels were significantly increased in psoriatic patients in comparison to the controls (p = 0.023). No significant correlations with indicators of inflammation, nor BMI or PASI were noted. A statistical association between lipocalin-2 and low-density lipoprotein-cholesterol was shown. After topical treatment serum lipocalin-2 level did not significantly change (p = 0.9), still remaining higher than in the controls, despite clinical improvement. Lipocalin-2 might be a marker of psoriasis and convey cardiovascular or metabolic risk in psoriatic patients, but may not be a reliable indicator of inflammation, severity of psoriasis nor efficacy of antipsoriatic treatment.

  15. Serum inflammatory mediators as markers of human Lyme disease activity.

    Full Text Available Chemokines and cytokines are key signaling molecules that orchestrate the trafficking of immune cells, direct them to sites of tissue injury and inflammation and modulate their states of activation and effector cell function. We have measured, using a multiplex-based approach, the levels of 58 immune mediators and 7 acute phase markers in sera derived from of a cohort of patients diagnosed with acute Lyme disease and matched controls. This analysis identified a cytokine signature associated with the early stages of infection and allowed us to identify two subsets (mediator-high and mediator-low of acute Lyme patients with distinct cytokine signatures that also differed significantly (p<0.0005 in symptom presentation. In particular, the T cell chemokines CXCL9 (MIG, CXCL10 (IP-10 and CCL19 (MIP3B were coordinately increased in the mediator-high group and levels of these chemokines could be associated with seroconversion status and elevated liver function tests (p = 0.027 and p = 0.021 respectively. There was also upregulation of acute phase proteins including CRP and serum amyloid A. Consistent with the role of CXCL9/CXCL10 in attracting immune cells to the site of infection, CXCR3+ CD4 T cells are reduced in the blood of early acute Lyme disease (p = 0.01 and the decrease correlates with chemokine levels (p = 0.0375. The levels of CXCL9/10 did not relate to the size or number of skin lesions but elevated levels of serum CXCL9/CXCL10 were associated with elevated liver enzymes levels. Collectively these results indicate that the levels of serum chemokines and the levels of expression of their respective chemokine receptors on T cell subsets may prove to be informative biomarkers for Lyme disease and related to specific disease manifestations.

However, the association of inflammation and oxidative stress in HTN with T2DM as a comorbidity is inconclusive due to the multifactorial nature of these cardiometabolic diseases. Methodology: The influence of pathophysiological factors include genetics, age of patient, and disease progression change throughout the lifespan and require further investigation. The study population included 256 participants attending a rural health screening program who were tested for markers of inflammation, oxidative stress, and coagulation/fibrinolysis. Demographic and clinical variables included, age, gender, systolic and diastolic blood pressures, blood glucose, hemoglobin A1c, estimated glomerular filtration rate, and cholesterol profile. Data were tested for normality, and nonparametric statistics were applied to analyze the sample with significance set at p<0.05. Results: Of the inflammatory markers, interleukin-1β (IL-1β and IL-10 were significantly different between the control and hypertensive group (p<0.03 and between the HTN+T2DM compared to the HTN group (p<0.05. Significant results for oxidative stress were observed for urinary 8-iso-PGF2α and insulin-like growth factor 1 (IGF-1 between the control and the HTN+T2DM group (p<0.01. Glutathione (GSH was also significant between the HTN and HTN+T2DM group (p<0.05.

    objective Nonalcoholic fatty liver disease (NAFLD) and its association with insulin resistance are increasingly recognized as major health burdens. The main objectives of this study were to assess the relation between liver lipid content and serum lipids, markers of liver function and inflammation in healthy overweight subjects, and to determine whether caloric restriction (CR) (which improves insulin resistance) reduces liver lipids in association with these same measures. Methods and Procedures Forty-six white and black overweight men and women (BMI = 24.7-31.3 kg/m2) were randomized to “control (CO)” = 100% energy requirements; “CR” = 25%; “caloric restriction and increased structured exercise (CR+EX)”= 12.5% CR + 12.5% increase in energy expenditure through exercise; or “low-calorie diet (LCD)” = 15% weight loss by liquid diet followed by weight-maintenance, for 6 months. Liver lipid content was assessed by magnetic resonance spectroscopy (MRS) and computed tomography (CT). Lipid concentrations, markers of liver function (alanine aminotransferase (ALT), alkaline phosphatase (ALK)), and whole-body inflammation (tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP)) were measured in fasting blood. Results At baseline, increased liver lipid content (by MRS) correlated (P triglyceride (r = 0.52), ALT (r = 0.42), and hsCRP (r = 0.33) concentrations after adjusting for sex, race, and alcohol consumption. With CR, liver lipid content was significantly lowered by CR, CR+EX, and LCD (detected by MRS only). The reduction in liver lipid content, however, was not significantly correlated with the reduction in triglycerides (r = 0.26; P = 0.11) or with the changes in ALT, high-density lipoprotein (HDL)-cholesterol, or markers of whole-body inflammation. Discussion CR may be beneficial for reducing liver lipid and lowering triglycerides in overweight subjects without known NAFLD. PMID:18421281

    Full Text Available Abstract Objectives: to determine the frequency of serum markers for hereditary and acquired thrombophilia and their association with pregnancy in women with Systemic Lupus Erythematosus (SLE. Methods: a case-control study was conducted among 25 pregnant women with SLE (study group and 32 pregnant women without known disease and with at least one previous pregnancy (control group. The presence of antiphospholipid antibodies and hereditary thrombophilia were examined in both groups. We used the y2 Test with Yates correction or Fisher's Exact Test to verify the associations and calculate the relative risk. Results: thrombophilia was present in 72.0% of pregnant women with SLE and in 6.0% of patients in the control group. A significant association was found between the presence of SLE and serum markers for hereditary thrombophilia / antiphospholipid antibodies (p<0.05. The relative risks for antiphospholipid antibodies were 13.20 (ICR95%= 1.81 - 96.46 in pregnant women with SLE, 7.26 (CI95%= 1.77 - 29.86 for the presence of serum markers of hereditary thrombophilia and 7.92 (CI95%= 2.62 - 3.94 for the presence of hereditary thrombophilia and/or antiphospholipid antibodies. Conclusions: the identification of markers for hereditary and/or acquired thrombophilia in pregnant women with lupus may be clinically useful to determine which patients have a higher risk of obstetric complications.

    Objective To identify circulating proteins that distinguish between active anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and remission in a manner complementary to markers of systemic inflammation. Methods Twenty-eight serum proteins representing diverse aspects of the biology of AAV were measured before and 6 months after treatment in a large clinical trial of AAV. Subjects (n=186) enrolled in the Rituximab in ANCA-Associated Vasculitis (RAVE) trial were studied. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were available for comparison. The primary outcome was the ability of markers to distinguish severe AAV (Birmingham Vasculitis Activity Score for Wegener’s granulomatosis (BVAS/WG)≥3 at screening) from remission (BVAS/WG=0 at month 6), using areas under receiver operating characteristic (ROC) curve (AUC). Results All subjects had severe active vasculitis (median BVAS/WG=8) at screening. In the 137 subjects in remission at month 6, 24 of the 28 markers showed significant declines. ROC analysis indicated that levels of CXCL13 (BCA-1), matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of metalloproteinases-1 (TIMP-1) best discriminated active AAV from remission (AUC>0.8) and from healthy controls (AUC>0.9). Correlations among these markers and with ESR or CRP were low. Conclusions Many markers are elevated in severe active AAV and decline with treatment, but CXCL13, MMP-3 and TIMP-1 distinguish active AAV from remission better than the other markers studied, including ESR and CRP. These proteins are particularly promising candidates for future studies to address unmet needs in the assessment of patients with AAV. PMID:22975753

    Histological type is important for determining the management of patients with suspicious lung cancers. In this study, PET/CT combined with serum tumor markers were used to evaluate the histological type of lung lesions. Patients with suspicious lung cancers underwent 18F-FDG PET/CT and serum tumor markers detection. SUVmax of the tumor and serum levels of tumor markers were acquired. Differences in SUVmax and serum levels of tumor markers among different histological types of lung cancers and between EGFR mutation statues of adenocarcinoma were compared. The diagnostic efficiencies of SUVmax alone, each serum tumor marker alone, combined tumor markers and the combination of both methods were further assessed and compared. SCC had the highest level of SUVmax, followed by SCLC and adenocarcinoma, and benign lesions had a lowest level. CYFRA21-1 and SCC-Ag were significantly higher in SCC, NSE was significantly higher in SCLC (Ptumor marker or SUVmax alone. When combined, the AUC, sensitivity and specificity increased significantly (Ptumor markers (P>0.05 for all). SUVmax and serum tumor markers show values in evaluating the histological types of suspicious lung cancers. When properly combined, the diagnostic efficiency can increase significantly.

    Inflammatory conditions characterized by excessive peripheral immune responses are associated with diverse alterations in brain function, and brain-derived neural pathways regulate peripheral inflammation. Important aspects of this bidirectional peripheral immune–brain communication, including the impact of peripheral inflammation on brain region–specific cytokine responses, and brain cholinergic signaling (which plays a role in controlling peripheral cytokine levels), remain unclear. To provide insight, we studied gene expression of cytokines, immune cell markers and brain cholinergic system components in the cortex, cerebellum, brainstem, hippocampus, hypothalamus, striatum and thalamus in mice after an intraperitoneal lipopolysaccharide injection. Endotoxemia was accompanied by elevated serum levels of interleukin (IL)-1β, IL-6 and other cytokines and brain region–specific increases in Il1b (the highest increase, relative to basal level, was in cortex; the lowest increase was in cerebellum) and Il6 (highest increase in cerebellum; lowest increase in striatum) mRNA expression. Gene expression of brain Gfap (astrocyte marker) was also differentially increased. However, Iba1 (microglia marker) mRNA expression was decreased in the cortex, hippocampus and other brain regions in parallel with morphological changes, indicating microglia activation. Brain choline acetyltransferase (Chat ) mRNA expression was decreased in the striatum, acetylcholinesterase (Ache) mRNA expression was decreased in the cortex and increased in the hippocampus, and M1 muscarinic acetylcholine receptor (Chrm1) mRNA expression was decreased in the cortex and the brainstem. These results reveal a previously unrecognized regional specificity in brain immunoregulatory and cholinergic system gene expression in the context of peripheral inflammation and are of interest for designing future antiinflammatory approaches.

    Full Text Available Chitosan treatment results in significantly lower serum low density lipoprotein (LDL cholesterol concentrations. To assess the working mechanisms of chitosan, we measured serum surrogate markers of cholesterol absorption (campesterol, sitosterol, cholestanol, synthesis (lathosterol, lanosterol, desmosterol, and degradation to bile acids (7α-hydroxy-cholesterol, 27-hydroxy-cholesterol, corrected for cholesterol concentration (R_sterols. Over 12 weeks, 116 obese subjects (Body Mass Index, BMI 31.7, range 28.1–38.9 kg/m2 were studied under chitosan (n = 61 and placebo treatments (n = 55. The participants were briefly educated regarding improvement of nutrition quality and energy expenditure. Daily chitosan intake was 3200 mg. Serum LDL cholesterol concentration decreased significantly more (p = 0.0252 under chitosan (−8.67 ± 18.18 mg/dL, 5.6% than under placebo treatment (−1.00 ± 24.22 mg/dL, 0.9%. This reduction was not associated with the expected greater decreases in markers of cholesterol absorption under chitosan treatment. Also, increases in markers of cholesterol synthesis and bile acid synthesis under chitosan treatment were not any greater than under placebo treatment. In conclusion, a significant selective reduction of serum LDL cholesterol under chitosan treatment is neither associated with a reduction of serum surrogate markers of cholesterol absorption, nor with increases of markers for cholesterol and bile acid synthesis.

    The aim of the study was to investigate white blood cell counts and neutrophil to lymphocyte ratio (NLR) as markers of systemic inflammation in the diagnosis of localized testicular cancer as a malignancy with initially low volume. Thirty-six patients with localized testicular cancer with a mean age of 34.22±14.89 years and 36 healthy controls with a mean age of 26.67±2.89 years were enrolled in the study. White blood cell counts and NLR were calculated from complete blood cell counts. White blood cell counts and NLR were statistically significantly higher in patients with testicular cancer compared with the control group (ptesticular cancer besides the well-known accurate serum tumor markers as AFP (alpha fetoprotein), hCG (human chorionic gonadotropin) and LDH (lactate dehydrogenase).

    Serum and bile tumor markers are under intense scrutiny for the diagnosis of malignant disease. The purpose of our study was to report the usefulness of serum and bile tumor markers for the discrimination between benign and malignant pancreatobiliary diseases. Between March 2010 and May 2013, 95 patients with obstructive jaundice or history of biliary obstruction, were included in the study. During ERCP, bile samples were obtained for measurement of tumor markers CEA, CA19- 9, CA125, CA72-4 and CA242. Serum samples were taken before ERCP for the same measurements. The patients were divided into two groups: patients with malignant disease and patients with benign disease. Serum tumor marker levels were significantly higher in patients with malignant disease. Serum CA242 and CA19-9 exhibited the highest diagnostic accuracy (76.8% and 73.7%, respectively). CA125 and CA72-4 levels in bile samples were significantly higher in patients with malignant disease. Bile CA125, CEA and CA72-4 achieved the best diagnostic accuracy (69, 65 and 65), respectively). The combined detection of CA19-9, CA242 in serum and CA125, CA72-4 in bile along with total bilirubin levels, showed the best diagnostic accuracy (81%). Serum and bile tumor markers, when studied alone, lack the diagnostic yield to discriminate benign from malignant pancreatobiliary diseases. In cases of diagnostic dilemmas the combination of serum and bile markers might be helpful.

    Brouwers, Corline; Versteeg, Henneke; Meine, Mathias

    2014-01-01

    Introduction: Studies suggest that cardiac resynchronization therapy (CRT) can induce a decrease in brain natriuretic peptide (BNP) and systemic inflammation, which may be associated with CRT-response. However, the evidence is inconclusive. We examined levels of BNP and inflammatory markers from...... ventricular end systolic volume; subjective CRT-response was defined as an improvement of ⩾10 points in patient-reported health status assessed with the Kansas City Cardiomyopathy Questionnaire. Plasma BNP and markers of inflammation (CRP, IL-6, TNFα, sTNFr1 and sTNFr2) were measured at three time points...... is not automatically related to a stronger overall decrease in inflammation. Large-scale studies are warranted that further examine the relation between the clinical effects of CRT on inflammatory markers, as the latter have been associated with poor prognosis in heart failure....

    Multiplexed analysis of cancer markers is crucial for early tumor diagnosis and screening. We have designed lab-on-a-bead microarray for quantitative detection of three breast cancer markers in human serum. Quantum dots were used as bead-bound fluorescent tags for identifying each marker by means of flow cytometry. Antigen-specific beads reliably detected CA 15-3, CEA, and CA 125 in serum samples, providing clear discrimination between the samples with respect to the antigen levels. The novel microarray is advantageous over the routine single-analyte ones due to the simultaneous detection of various markers. Therefore the developed microarray is a promising tool for serum tumor marker profiling.

    Gastric cancer (GC) is a second most common cause of cancer-related death and represents an inflammation-driven malignancy. It has been suggested that interleukin 6 (IL-6) and C-reactive protein (CRP) play a potential role in the growth and progression of GC. The aim of the present study was to compare clinical significance of IL-6 and CRP with classic tumor markers-carcinoembryonic antigen (CEA) and carbohydrate antigen (CA 19-9) in GC patients. The study included 92 patients with GC and 70 healthy subjects. The serum concentrations of IL-6, CEA and CA 19-9 were determined using immunoenzyme assays, whereas CRP using immunoturbidimetric method. We defined the diagnostic criteria and prognostic value for proteins tested. In GC patients, the serum concentrations of all the proteins tested were significantly higher than in healthy subjects. The IL-6, CEA and CA 19-9 levels correlated with nodal metastases, while CRP with tumor stage, gastric wall invasion, presence of nodal and distant metastases. Diagnostic sensitivity of IL-6 was higher (85%) than those of other markers (CRP 66%, CA 19-9 34%, CEA 22%) and increased in combined use with CRP or CEA (88%). The area under ROC curve for IL-6 was larger than those of CRP and classic tumor markers (CEA and CA 19-9). None of the proteins tested was independent prognostic factor for the survival of GC patients. Our findings indicate better usefulness of serum proinflammatory proteins-IL-6 and CRP than classic tumor markers-CEA and CA 19-9 in the diagnosis of GC.

    A new immunoradiometric assay based on dual monoclonal antibody reaction system (Hybritech-TANDEM/sup R/) was used to measure serum levels of prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) in 39 patients with prostatic carcinoma (CaP), in 57 with benign prostatic hyperplasia (BPH) and in 14 without prostatic disease. Serum PSA was elevated in 82% of patients with CaP while PAP was elevated in only 54%. In this and other studies, PSA is superior to conventional serum markers in sensitivity, prediction of CaP stage and in longitudinal monitoring of disease. A 16% false positive rate precludes PSA as a screening test. The assay used was found to be simple and reliable.

    Calprotectin is a marker of inflammation and zonulin is a marker of intestinal permeability. Diets with lower carbohydrate content and higher contents of fat, fiber and protein, e.g., Okinawan-based diet, are considered to reduce inflammation and intestinal permeability. The aim of the present study was to evaluate calprotectin and zonulin levels in serum and feces after intervention with an Okinawan-based Nordic diet. Thirty patients (17 women) with type 2 diabetes, mean age 57.5±8.2 years, BMI 29.9±4.1 kg/m 2 , were served the diet during 12 weeks, and were followed for another 16 weeks. Anthropometric and metabolic parameters were registered. Fasting levels of calprotectin and zonulin in serum and feces, and hormones in plasma, were measured by Luminex or ELISA before study start and after 12 and 28 weeks. Calprotectin in serum tended to be increased (P=0.074) after 12 weeks. Zonulin in serum and feces were elevated after 12 weeks (P=0.019 vs. Pvs. P=0.079). Energy percentage of protein in breakfast correlated with serum calprotectin (P=0.008) and tended to correlate with serum zonulin (P=0.059). Calprotectin in serum tended to be elevated, and zonulin in serum and feces are elevated after introduction of an Okinawan-based Nordic diet. These biomarkers correlate with energy percentage of protein.

    Biomarker testing can be helpful to monitor disease progression after resection of pancreatic cancer. This systematic review aims to give an overview of the literature on the diagnostic value of serum tumor markers for the detection of recurrent pancreatic cancer during follow-up. A systematic search was performed to 2 October 2017. All studies reporting on the diagnostic value of postoperatively measured serum biomarkers for the detection of pancreatic cancer recurrence were included. Data on diagnostic accuracy of tumor markers were extracted. Forest plots and pooled values of sensitivity and specificity were calculated. Four articles described test results of CA 19-9. A pooled sensitivity and specificity of respectively 0.73 (95% CI 0.66-0.80) and 0.83 (95% CI 0.73-0.91) were calculated. One article reported on CEA, showing a sensitivity of 50% and specificity of 65%. No other serum tumor markers were discussed for surveillance purposes in the current literature. Although testing of serum CA 19-9 has considerable limitations, CA 19-9 remains the most used serum tumor marker for surveillance after surgical resection of pancreatic cancer. Further studies are needed to assess the role of serum tumor marker testing in the detection of recurrent pancreatic cancer and to optimize surveillance strategies.

    2016-01-01

    Cancer is singled out as the biggest cause of death in the world, predicted to reach 13.1 million cancer-related deaths by the year 2030. Although there are no specific tumor markers used in cancer screening, some markers can be used to assist in making a diagnosis and determining a prognosis. They can be used to follow in cases where the diagnosis is cancer through monitoring of the disease recurrence and/or evaluating the response to therapy. These markers are not specific as the number increases in multiple cases of cancer. Some markers are positive in a single type of cancer; others are detectable in more than one type. An ideal tumor marker should be highly sensitive, specific, and reliable with high prognostic value. Other characteristics of an ideal tumor marker are organ specificity and correlation of it with tumor stages. However, none of the tumor markers reported to date has all these characteristics. Influence of different stages of chronic kidney function on serum tumor markers is variable. Furthermore, hemodialysis, peritoneal dialysis, and kidney transplantation affect on tumor markers differently. Sometimes, no study has been found in the literature review. Combined serum tumor markers may also be valuable. This literature review points the role of serum tumor markers in screening, diagnosis, and follow-up of cancer patients in chronic kidney disease patients and renal allograft recipients. In addition, impact of chronic kidney disease and kidney transplantation on different serum tumor markers is briefly explored.

    Obesity is one of the most prevalent health problems in the canine population. While haemostatic parameters and markers of endothelial function have been evaluated in various disease conditions in dogs, there are no studies of these markers in canine obesity. This study was designed to evaluate the effect of naturally gained weight excess and obesity on inflammatory, hemostatic and endothelial biomarkers in dogs. A total of 37 overweight and obese dogs were compared with 28 normal weight dogs. Overweight and obese dogs had significantly elevated concentrations of serum interleukin-6 (IL-6) and C-reactive protein (hsCRP). Number of platelets, activity of factor X and factor VII were significantly higher, while activated partial thromboplastine time (aPTT) and soluble plasminogen activator receptor (suPAR) were significantly decreased. Statistical analysis of high mobility group box - 1 protein (HMGB-1), soluble intercellular adhesive molecule -1 (sICAM-1) and plasminogen activator inhibitor type 1 (PAI-1) concentrations did not show significant differences between the total overweight and obese group and the normal weight group of dogs. Analytical changes in the dogs in our study reflects that weight excess in dogs can be associated with a chronic low degree of inflammation and a hypercoagulable state, where primary and secondary hemostasis are both affected. However obesity is not associated with impairment of endothelial function in dogs.

    Metabolic syndrome is associated with chronic low-grade inflammation, a condition thought to play a key role in the pathogenesis of the syndrome. Among a number of proinflammatory cytokines, interleukin-18 (IL-18) seems to be the best marker for inflammation among people with metabolic syndrome. The aim of this study was to examine the effect of aerobic training versus strength training on circulating IL-18 and other proinflammatory markers in people with metabolic syndrome. Thirty-one inactive men and women with metabolic syndrome were randomized to either high-intensity aerobic interval training (AIT, n=11), strength training (ST, n=10), or a control group (n=10). Exercise training was carried out three times per week for 12 weeks. Serum insulin, high-sensitivity C-reactive protein (hsCRP), IL-18, IL-6, and tumor necrosis factor-α (TNF-α) were measured before and after the intervention. Serum IL-18 was reduced by 43% after AIT (Pmetabolic syndrome. http://clinicaltrials.gov/show/NCT00986024/ .

    Exposure to traffic-related air pollution is a risk factor for cardiovascular events, probably involving mechanisms of inflammation and coagulation. Little is known about effects of the short exposures encountered while participating in traffic. The objective of the study was to examine effects of exposure of commuters to air pollution on cardiovascular biomarkers. Thirty-four healthy adult volunteers commuted for 2 hr by bus, car, or bicycle during the morning rush hour. During the commute, exposure to particle number, particulate matter (PM) ≤ 2.5 µm in aerodynamic diameter (PM2.5), PM ≤ 10 µm in diameter (PM10), and soot was measured. We estimated inhaled doses based on heart rate monitoring. Shortly before exposure and 6 hr after exposure, blood samples were taken and analyzed for CC16 (Clara cell protein 16), blood cell count, coagulation markers, and inflammation markers. Between June 2007 and June 2008, 352 pre- and postexposure blood samples were collected on 47 test days. We used mixed models to analyze the associations between exposure and changes in health parameters. We observed no consistent associations between the air pollution exposures and doses and the various biomarkers that we investigated. Air pollution exposure during commuting was not consistently associated with acute changes in inflammation markers, blood cell counts, or blood coagulation markers.

    Mental disorders constitute 13% of the global disease burden. Schizophrenia, major depressive disorders (MDD) and bipolar disorders are among the most disabling disorders. Some of the inflammatory markers such as homocysteine, tumor necrosis alpha (TNF), C-reactive protein (CRP), and interleukin (IL)-6 have a contribution to influence mental disorder. The serum concentration of C-reactive protein (CRP) wasusedas a nonspecific index of systemic inflammation. Elevated levels of CRP as evidence for an inflammatory etiology of schizophrenia, and as indicators of more severe clinical symptoms and psychopathology of schizophrenia. The inflammatory marker also increases in the depressed patient. Proinflammatory cytokines might inhibit hippocampal neurogenesis which could lead to a reduced hippocampal volume, which is in depression. Anxiety symptoms were correlated to increase cytokine levels. Elevated inflammation in particular found in both men and women with the onset of anxiety disorder later in life.

  4. Liver stiffness measurement-based scoring system for significant inflammation related to chronic hepatitis B.

    Full Text Available Liver biopsy is indispensable because liver stiffness measurement alone cannot provide information on intrahepatic inflammation. However, the presence of fibrosis highly correlates with inflammation. We constructed a noninvasive model to determine significant inflammation in chronic hepatitis B patients by using liver stiffness measurement and serum markers.The training set included chronic hepatitis B patients (n = 327, and the validation set included 106 patients; liver biopsies were performed, liver histology was scored, and serum markers were investigated. All patients underwent liver stiffness measurement.An inflammation activity scoring system for significant inflammation was constructed. In the training set, the area under the curve, sensitivity, and specificity of the fibrosis-based activity score were 0.964, 91.9%, and 90.8% in the HBeAg(+ patients and 0.978, 85.0%, and 94.0% in the HBeAg(- patients, respectively. In the validation set, the area under the curve, sensitivity, and specificity of the fibrosis-based activity score were 0.971, 90.5%, and 92.5% in the HBeAg(+ patients and 0.977, 95.2%, and 95.8% in the HBeAg(- patients. The liver stiffness measurement-based activity score was comparable to that of the fibrosis-based activity score in both HBeAg(+ and HBeAg(- patients for recognizing significant inflammation (G ≥3.Significant inflammation can be accurately predicted by this novel method. The liver stiffness measurement-based scoring system can be used without the aid of computers and provides a noninvasive alternative for the prediction of chronic hepatitis B-related significant inflammation.

    The epidemic of childhood obesity is associated with early atherosclerosis. Several reports have related this event to low-grade inflammation described in obesity. CRP and IL6 are markers that correlate with adiposity. The waist-to-height ratio (WtHR) is an anthropometric marker associated with insulin resistance and inflammation. The objective of this study was to assess the correlation between WtHR, metabolic complications and pro-inflammatory factors in obese children and adolescents. Weight, height, waist circumference, glycemia, insulin, CRP, TNF-α and IL-6 were measured in the baseline sample in 280 patients 6-19 years of age with overweight or obesity (OW/OB) and 112 normal-weight controls. Logistic regression was performed using WtHR as an independent variable. p>0.05 STATA11. Mean WtHR was 0.6±0.06 in OW/OB and 0.43±0.02 in controls (p0.5, insulin resistence and inflammatory markers were significantly increased (p<0.01) compared to the WtHR<0.5 (HOMA 3.4 vs. 1.4; CRP 2.3 vs. 0.6; Il-6 2.9 vs. 2.1; and TNF-α 6.4 vs. 5.55). In logistic regression, a significant independent association was found between WtHR with CRP (OR1.47), IL6 (OR1.60) and TNF-α (OR1.79). Obese children and adolescents have high inflammatory markers that may increase cardiovascular risk. WtHR is associated with low-grade inflammation and may be considered a relevant anthropometric marker in the clinical practice.

  6. The role of serum non-cholesterol sterols as surrogate markers of absolute cholesterol synthesis and absorption.

    2011-10-01

    To study the whole-body cholesterol metabolism in man, cholesterol synthesis and absorption need to be measured. Because of the complicated methods of the measurements, new approaches were developed including the analysis of serum non-cholesterol sterols. In current lipidologic papers and even in intervention studies, serum non-cholesterol sterols are frequently used as surrogate markers of cholesterol metabolism without any validation to the absolute metabolic variables. The present review compares serum non-cholesterol sterols with absolute measurements of cholesterol synthesis and absorption in published papers to find out whether the serum markers are valid indicators of cholesterol metabolism in various conditions. During statin treatment, during interventions of dietary fat, and in type 2 diabetes the relative and absolute variables of cholesterol synthesis and absorption were frequently but not constantly correlated with each other. In some occasions, especially in subjects with apolipoprotein E3/4 and E4/4 phenotypes, the relative metabolic markers were even more sensitive than the absolute ones to reflect changes in cholesterol metabolism during dietary interventions. Even in general population at very high absorption the homeostasis of cholesterol metabolism is disturbed damaging the validity of the serum markers. It is worth using several instead of only one precursor and absorption sterol marker for making conclusions of altered synthesis or absorption of cholesterol, and even then the presence of at least some absolute measurement is valuable. During consumption of plant sterol-enriched diets and in situations of interfered cholesterol homeostasis the relative markers do not adequately reflect cholesterol metabolism. Accordingly, the validity of the relative markers of cholesterol metabolism should not be considered as self-evident. Copyright © 2011 Elsevier B.V. All rights reserved.

    Progranulin is an adipokine that is involved in the inflammatory response, glucose metabolism, insulin resistance, and may therefore be involved in chronic subclinical inflammation associated with the pathogenesis of childhood obesity. We aimed to investigate the association of circulating progranulin levels with metabolic parameters in children and to assess the importance of progranulin as a biomarker for metabolic diseases. A total of 150 children were consecutively recruited from the Pediatric Nutrition Clinics at King Abdulaziz University Hospital in Jeddah, Saudi Arabia. Children were classified into four groups based on quartile for serum progranulin. Anthropometric variables were measured in all study subjects. Fasting blood samples were collected for measurement of blood glucose, insulin and lipid profile. Children within the upper quartile for serum progranulin concentration were heavier, more insulin resistant and had higher concentrations of serum total cholesterol, triglycerides, insulin and high sensitivity C reactive protein compared to those in the lower quartile. On correlation analysis, serum progranulin concentrations were significantly related to general and central adiposity, metabolic parameters, markers of inflammation and insulin resistance. Stepwise multiple regression showed that 26.6% of the variability in serum progranulin could be explained by measures of adiposity. The increased serum progranulin concentrations were closely related to measures of adiposity, metabolic parameters, inflammatory marker and insulin resistance indices, suggesting that progranulin may be an excellent biomarker for obesity in childhood.

    The traditional Inuit diet in Greenland consists mainly of fish and marine mammals, rich in vitamin D. Vitamin D has anti-inflammatory capacity but markers of inflammation have been found to be high in Inuit living on a marine diet. Yet, the effect of vitamin D on inflammation in Inuit remains...... unsettled. This led us to investigate the association between vitamin D and markers of inflammation in a population with a high intake of a marine diet. We studied 535 Inuit and non-Inuit living in West and East Greenland. Information concerning dietary habits was obtained by interview-based FFQ. Blood...... samples were drawn for analysis of 25-hydroxyvitamin D, high-sensitivity C-reactive protein (hsCRP) and chitinase-3-like protein 1(YKL-40). Participants were divided into three groups based on degree of intake of the traditional Inuit diet. The diet groups (Inuit diet/mixed diet/imported foods) were...

    Chronic obstructive pulmonary disease (COPD) is a worldwide burden and a major cause of death. The disease is accompanied by chronic inflammation and increased cellular turnover that is partly due to an overwhelming induction of apoptosis. In this study, we hypothesized that systemic markers of apoptosis are altered in patients with mild-to-severe COPD. A total number of 64 patients and controls were enrolled in the study. Lung function parameters of all groups (nonsmoker, healthy smoker, COPD GOLD I&II, COPD GOLD III&IV) were evaluated at the time of inclusion. Enzyme-linked immunosorbent assays were used to quantify protein levels in serum samples. Serum contents of apoptotic end-products caspase-cleaved cytokeratin-18 and histone-associated-DNA-fragments were increased in patients with COPD, whereas anti-inflammatory soluble ST2 showed a peak in patients with COPD I&II (P=0.031) compared to healthy smokers. Levels of pro-inflammatory caspase-1/ ICE correlated significantly with the number of pack years (R=0.337; P=0.007). Our results indicate a systemic release of apoptosis-specific proteins as markers for increased cellular turnover accompanied by progression of COPD. Furthermore, soluble ST2 seems to have a critical role in the anti-inflammatory regulatory mechanism at early stages of the disease.

    Full Text Available Diabetes has been associated with periodontitis, but the mechanisms through which periodontal diseases affect the metabolic control remain unclear. Objective: This study aimed to evaluate serum leveis of inflammatory markers, IL-8, IL-6 and monocyte chemoattractant protein 1 (MCP-1, in type 2 diabetic patients in the presence of chronic periodontitis. Material and Methods: Forty two individuals were enrolled in this study and assigned to one of five groups: diabetes mellitus with inadequate glycemic control and periodontitis (DMI+P, n = 10, diabetes mellitus with adequate glycemic control and periodontitis (DMA+P, n = 10, diabetes mellitus without periodontitis (DM, n = 10, periodontitis without diabetes (P, n=6, and neither diabetes nor periodontitis (H, n = 6. Periodontal clinical examination included visible plaque index (PL, gingival bleeding index (GB, probing depth (PD, attachment level (AL and bleeding on probing (BP. Glycemic control was evaluated by serum concentration of glycated hemoglobin (HbAlc. Inflammatory serum markers IL-8, IL-6 and (MCP-1 were measured by ELISA. Results: DMI+P and DMA+P groups presented higher PD (p=0.025 and AL (p=0.003 values when compared to the P group. There were no significant differences among groups for IL-6, IL-8 and MCP-1 serum levels. Conclusions: Although periodontitis was more severe in diabetic patients, the serum levels of the investigated inflammatory markers did not differ among the groups.

    Full Text Available Background/Aim. Unknown primary tumors represent a heterogeneous group of malignancies that are indicative of ominous prognosis. Cancer of unknown primary site (CUP is defined as the lack of any detectable primary site after full evaluation, and accounts for approximately 3-5% of all newly diagnosed patients with malignancies. The aim of this report was to present the prognostic and predictive value of 8 serum tumor markers in this group of patients. Methods. The study involved 63 patients. On histological examination, all the patients were presented with metastatic tumors whose primary site (origin could not be detected with noninvasive diagnostic techniques. Following the routine light microscopy, all histological findings were classified into one of the following three groups: plano-cellular carcinoma - 8 patients; adenocarcinoma - 33 patients; unclassifiable (undifferentiated carcinoma - 22 patients. In all the cases we evaluated 8 serum tumor markers: alpha-fetoproteins (AFP, chronic gonadotrophin beta submit, human (beta-HCG, neuron specific enolase (NSE, marker of malignant ovarian tumors (CA 125, prostate-specific antigene (PSA, marker of malignant brest tumor (CA 15-3, marker of malignant pancreas tumor and gastrointestinal tumor (Ca 19-9, carcinoembryonic antigen (CEA at the time of diagnosis. The patients on chemotherapy had the markers determined after the third and sixth chemocycle, i.e. at the time of illness progression observation, if present. The patients responding to chemotherapy with complete response (CR, partial response (PR or stable disease (SD had the markers determined after three-month periods until the time of relapse or progression. Chemotherapy was applied in 32 patients (20 females and 12 males, aged 29-70 years, who met the inclusion criteria. The following chemotherapy regimen was used: doxorubicin 50mg/m2 (day 1, cisplatin 60mg/m2 (day 1, and etoposide 120 mg/m2 (days 1-3. The period between two chemotherapy

    Full Text Available Abstract Background An inflammatory component is present in the microenvironment of most neoplastic tissues. Inflammation and elevated C-reactive protein (CRP are associated with poor prognosis and decreased survival in many types of cancer. Vitamin C has been suggested as having both a preventative and therapeutic role in a number of pathologies when administered at much higher-than-recommended dietary allowance levels. Since in vitro studies demonstrated inhibition of pro-inflammatory pathways by millimolar concentrations of vitamin C, we decided to analyze the effects of high dose IVC therapy in suppression of inflammation in cancer patients. Methods 45 patients with prostate cancer, breast cancer, bladder cancer, pancreatic cancer, lung cancer, thyroid cancer, skin cancer and B-cell lymphoma were treated at the Riordan Clinic by high doses of vitamin C (7.5 g -50 g after standard treatments by conventional methods. CRP and tumor markers were measured in serum or heparin-plasma as a routine analysis. In addition, serum samples were collected before and after the IVCs for the cytokine kit tests. Results According to our data positive response to treatment, which was demonstrated by measurements of C- reactive protein, was found in 75% of patients and progression of the inflammation in 25% of patients. IVC treatments on all aggressive stage cancer patients showed the poor response of treatment. There was correlation between tumor markers (PSA, CEA, CA27.29 and CA15-3 and changes in the levels of C-reactive protein. Our test of the effect of IVC on pro-inflammatory cytokines demonstrated that inflammation cytokines IL-1α, IL-2, IL-8, TNF-α, chemokine eotaxin and CRP were reduced significantly after treatments. Conclusions The high dose intravenous ascorbic acid therapy affects C-reactive protein levels and pro-inflammation cytokines in cancer patients. In our study, we found that modulation of inflammation by IVC correlated with decreases

    to compare serum markers of oxidative stress between infertile patients with and without endometriosis and to assess the association of these markers with disease staging. this was a prospective study conducted on 112 consecutive infertile, non-obese patients younger than 39 years, divided into two groups: Endometriosis (n=48, 26 with minimal and mild endometriosis - Stage I/II, and 22 with moderate and severe endometriosis - Stage III/IV) and Control (n=64, with tubal and/or male factor infertility). Blood samples were collected during the early follicular phase of the menstrual cycle for the analysis of serum malondialdehyde, glutathione and total hydroxyperoxide levels by spectrophotometry and of vitamin E by high performance liquid chromatography. The results were compared between the endometriosis and control groups, stage I/II endometriosis and control, stage III/IV endometriosis and control, and between the two endometriosis subgroups. The level of significance was set at 5% (p Control Group (8.0 ± 2 µMol/g protein) and among patients with stage III/IV disease (9.7 ± 2.3 µMol/g protein) compared to patients with stage I/II disease (8.2 ± 1.0 µMol/g protein). No significant differences in serum malondialdehyde levels were observed between groups. we demonstrated a positive association between infertility related to endometriosis, advanced disease stage and increased serum hydroxyperoxide levels, suggesting an increased production of reactive species in women with endometriosis. These data, taken together with the reduction of serum vitamin E and glutathione levels, suggest the occurrence of systemic oxidative stress in women with infertility associated with endometriosis. The reproductive and metabolic implications of oxidative stress should be assessed in future studies.

    Full Text Available Lyme disease (LD is the most prevalent tick-borne disease in Europe. LD is caused by the spirochete Borrelia burgdorferi. LD is a chronic disease which can attack a number of organs: skin, heart, brain, joints. Chronic, low-grade inflammation involves general production of pro-inflammatory cytokines and inflammatory markers and is a typical feature of aging. So far, the best method of diagnosing LD is a time-consuming and expensive two-stage serological method. The aim of our study was to evaluate the activity of two lysosomal exoglycosidases: α-fucosidase (FUC and β-galactosidase (GAL in the serum of patients with Lyme disease, as potential markers of LD. Due to the increasing number of patients with Lyme disease and a number of false results, new ways to diagnose this disease are still being sought. As elevated level of β-galactosidase is a manifestation of residual lysosomal activity in senescent cells, the increase in its activity in serum during chronic Lyme disease might be a marker of a potentially accelerated senescence process. The study was performed on serum taken from cubital veins of 15 patients with Lyme disease and eight healthy subjects (control group. FUC and GAL activity was measured by the method of Chatterjee et al. as modified by Zwierz et al. In the serum of patients with Lyme disease, GAL activity significantly increased (p = 0.029, and the activity of FUC had a tendency to increase (p = 0.153, compared to the control group. A significant increase in GAL activity in the serum of patients with Lyme disease indicates an increased catabolism of glycoconjugates (glycoproteins, glycolipids, proteoglycans and could be helpful in the diagnosis of Lyme disease, although this requires confirmation in a larger group of patients. As GAL is the most widely used assay for detection of senescent cells, an elevated level of β-galactosidase might be a manifestation of accelerated senescence process in the course of Lyme

    Body mass index (BMI), serum cytokines and serum obesity markers were evaluated in 33 obese children before, during and after a hypocaloric diet. The cytometric bead array "human inflammatory kit" was used for the evaluation of serum interleukin (IL)-1beta, IL-6, IL-10 and tumor necrosis factor-alpha. On the other hand, the following obesity biomarkers were evaluated by means of a flowcytomix-human obesity 9 plex kit: Soluble Isoform of CD40 Ligand; Soluble Intercellular Adhesion Molecule-1; Leptin; Monocyte Chemoattractant Protein 1; Myeloperoxidase; Osteoprotegerin; Resistin and Soluble TNF-receptors. Actually, throughout the study modifications of BMI were negligible and, therefore, serum cytokines and obesity markers did not show any significant changes in comparison with baseline values. On the other hand, at the different time points considered the majority of obesity markers were higher than normal controls, thus indicating a low grade inflammation in childhood obesity. Therefore, attempts at reducing this inflammatory status in children which predisposes to the metabolic syndrome outcome are discussed.

    The expression of P53 was previously found by us significantly correlated with maximal standardized uptake value (SUVmax) in non-small cell lung cancer (NSCLC) patients. Hence, the aim of this study was to clarify the relationship between SUVmax and the status of the chemotherapy-related tumor marker expression or serum tumor markers in gastric adenocarcinoma patients. Sixty-four gastric adenocarcinoma patients who underwent 18F-FDG PET/CT prior to treatment were enrolled in this study. Immunohistochemistry was performed to detect changes of Her-2, P53 and Survivin in lesions, and electrochemiluminescence (ECL) method was used to quantify expression of serum CA72-4, CA19-9 and CEA of these patients. Then, the relationships between these parameters above were assessed by Spearman correlation analysis. Also, receiver-operating characteristic (ROC) curve was performed to determine the best cut-off value of SUVmax for suggesting chemotherapy resistant tumor markers. Besides, we identified a linear correlation to estimate the equations between SUVmax and the serum tumor markers. Our results showed that higher SUVmax was detected in patients with positive expression of Her-2 and P53, compared with negative groups. The Spearman correlation analysis showed that SUVmax was associated with Her-2 or P53 with the moderate relevant Pearson correlation coefficient. ROC curve analysis showed that the sensitivity and specificity of SUVmax for suggesting Her-2 or P53-positive, when the cut-off value of SUVmax was set at 3.25 or 5.45, respectively. Moreover, the relationship between SUVmax and serum tumor markers were analyzed by linear correlation analysis, and serum CA72-4 and CA19-9 could be used as independent parameters to establish an equation for SUVmax by the linear regression models. These results suggested that SUVmax of 18F-FDG PET/CT could be used to predict and evaluate Her-2 or P53 related chemotherapy resistance of gastric adenocarcinoma patients. However, before PET

    Full Text Available BACKGROUND Biochemical markers of inflammation could be useful to predict severity of stroke in acute phase. Stroke is the third cause of mortality and the first cause of disability. Recent literature have demonstrated that inflammation contributes to all phases of atherosclerosis. The results of researchers suggest that atherosclerosis is an inflammatory disease. The aim of the study is to assess the1. Level of peripheral inflammatory markers in acute ischaemic stroke and their relation to severity of acute stroke. 2. Value of inflammatory markers in predicting the short-term outcome and disability at the end of six months. MATERIALS AND METHODS This is a prospective case control study for 6 months done from September 2014 to August 2016 in 100 patients of acute ischaemic stroke within first 5 days of symptom onset in comparison >18 years of age with 50 age and sex matched controls. Blood samples for all cases and controls were sent for erythrocyte sedimentation rate, Neutrophil-to-Lymphocyte Ratio (NLR, hs-C-reactive protein, mean platelet volume, serum ferritin, serum albumin and S. gamma-glutamyl transferase at admission. RESULTS The mean values of ESR, NLR, hs-CRP in all the cases are higher when compared to the controls and are statistically significant, whereas the mean values of MPV, S. ferritin, S. albumin and GGT in cases are lower when compared to controls, but are within normal range and difference is statistically significant except ferritin. ESR, hs-CRP has significant correlation with severity of acute ischaemic stroke. The mean values of these markers increased with increase in severity. Serum albumin has significant correlation with severity of acute ischaemic stroke with mean values of these markers decreasing with increase in severity of stroke. There is no significant correlation of the inflammatory markers in present study with the short-term outcome. CONCLUSION Inflammation plays an important role in the pathogenesis of non

    Full Text Available Purpose: We investigated if oral ingestion of ibuprofen influenced leucocyte recruitment and infiltration following an acute bout of traditional resistance exercise. Methods: Sixteen male subjects were divided into two groups that received the maximum over-the-counter dose of ibuprofen (1200 mg d-1 or a similarly administered placebo following lower body resistance exercise. Muscle biopsies were taken from m.vastus lateralis and blood serum samples were obtained before and immediately after exercise, and at 3 h and 24 h after exercise. Muscle cross-sections were stained with antibodies against neutrophils (CD66b and MPO and macrophages (CD68. Muscle damage was assessed via creatine kinase and myoglobin in blood serum samples, and muscle soreness was rated on a ten-point pain scale. Results: The resistance exercise protocol stimulated a significant increase in the number of CD66b+ and MPO+ cells when measured 3 h post exercise. Serum creatine kinase, myoglobin and subjective muscle soreness all increased post-exercise. Muscle leucocyte infiltration, creatine kinase, myoglobin and subjective muscle soreness were unaffected by ibuprofen treatment when compared to placebo. There was also no association between increases in inflammatory leucocytes and any other marker of cellular muscle damage. Conclusion: Ibuprofen administration had no effect on the accumulation of neutrophils, markers of muscle damage or muscle soreness during the first 24 h of post-exercise muscle recovery.

    To study the serum tumor markers in patients with multiple abnormal concentration of radiopharmaceuticals in whole body bone imagine, 73 patients with malignancy were under a whole body bone scan. The serum tumor markers levels of AFP, CEA, CA125, CA15-3 and CA19-9 were measured in 73 patients and 37 normal people. The results showed that there was significant difference only on serum CEA level (P<0.005), and no significant difference on CA125, CA15-3 and CA19-9 levels (P<0.05) between 36 patients with multiple abnormal concentration and the others with normal bone imagine. The serum levels of CEA, CA125 and CA19-9 in patients were significant higher than that of normal controls (P<0.005). Combined the whole body bone scan and detection of serum tumor markers might be regarded as clinical significance for the diagnosis of bone metastases. (authors)

  20. Detection of Pathogen Exposure in African Buffalo Using Non-Specific Markers of Inflammation

    Full Text Available Detecting exposure to new or emerging pathogens is a critical challenge to protecting human, domestic animal, and wildlife health. Yet, current techniques to detect infections typically target known pathogens of humans or economically important animals. In the face of the current surge in infectious disease emergence, non-specific disease surveillance tools are urgently needed. Tracking common host immune responses indicative of recent infection may have potential as a non-specific diagnostic approach for disease surveillance. The challenge to immunologists is to identify the most promising markers, which ideally should be highly conserved across pathogens and host species, become upregulated rapidly and consistently in response to pathogen invasion, and remain elevated beyond clearance of infection. This study combined an infection experiment and a longitudinal observational study to evaluate the utility of non-specific markers of inflammation [NSMI; two acute phase proteins (haptoglobin and serum amyloid A, two pro-inflammatory cytokines (IFNγ and TNF-α] as indicators of pathogen exposure in a wild mammalian species, African buffalo (Syncerus caffer. Specifically, in the experimental study, we asked (1 How quickly do buffalo mount NSMI responses upon challenge with an endemic pathogen, foot-and-mouth disease virus; (2 for how long do NSMI remain elevated after viral clearance and; (3 how pronounced is the difference between peak NSMI concentration and baseline NSMI concentration? In the longitudinal study, we asked (4 Are elevated NSMI associated with recent exposure to a suite of bacterial and viral respiratory pathogens in a wild population? Among the four NSMI that we tested, haptoglobin showed the strongest potential as a surveillance marker in African buffalo: concentrations quickly and consistently reached high levels in response to experimental infection, remaining elevated for almost a month. Moreover, elevated haptoglobin was

    Full Text Available The overall burden of chronic disease, inflammation and cardiovascular risk increases with age. Whether the relationship between age and inflammation is impacted by presence of an adverse metabolic burden is not known.We determined inflammatory markers in humans (336 Caucasians and 224 African Americans and in mice, representing a spectrum of age, weight and metabolic burden.In humans, levels of inflammatory markers increased significantly with age in subjects without the metabolic syndrome, (P=0.009 and P=0.037 for C-reactive protein, P<0.001 and P=0.001 for fibrinogen, P<0.001 and P=0.005 for serum amyloid-A, for Caucasians and African Americans, respectively. In contrast, trend patterns of inflammatory markers did not change significantly with age in subjects with metabolic syndrome in either ethnic group, except for fibrinogen in Caucasians. A composite z-score for systemic inflammation increased significantly with age in subjects without metabolic syndrome (P=0.004 and P<0.006 for Caucasians and African Americans, respectively but not in subjects with metabolic syndrome (P=0.009 for difference in age trend between metabolic syndrome and non-metabolic syndrome. In contrast, no similar age trend was found in vascular inflammation. The findings in humans were paralleled by results in mice as serum amyloid-A levels increased across age (range 2-15 months, P<0.01 and were higher in ob/ob mice compared to control mice (P<0.001.Presence of a metabolic challenge in mice and humans influences levels of inflammatory markers over a wide age range. Our results underscore that already at a young age, presence of a metabolic burden enhances inflammation to a level that appears to be similar to that of decades older people without metabolic syndrome.

    To evaluate serum concentrations of biochemical markers and survival time in dogs with protein-losing enteropathy (PLE). Prospective study. 29 dogs with PLE and 18 dogs with food-responsive diarrhea (FRD). Data regarding serum concentrations of various biochemical markers at the initial evaluation were available for 18 of the 29 dogs with PLE and compared with findings for dogs with FRD. Correlations between biochemical marker concentrations and survival time (interval between time of initial evaluation and death or euthanasia) for dogs with PLE were evaluated. Serum C-reactive protein concentration was high in 13 of 18 dogs with PLE and in 2 of 18 dogs with FRD. Serum concentration of canine pancreatic lipase immunoreactivity was high in 3 dogs with PLE but within the reference interval in all dogs with FRD. Serum α1-proteinase inhibitor concentration was less than the lower reference limit in 9 dogs with PLE and 1 dog with FRD. Compared with findings in dogs with FRD, values of those 3 variables in dogs with PLE were significantly different. Serum calprotectin (measured by radioimmunoassay and ELISA) and S100A12 concentrations were high but did not differ significantly between groups. Seventeen of the 29 dogs with PLE were euthanized owing to this disease; median survival time was 67 days (range, 2 to 2,551 days). Serum C-reactive protein, canine pancreatic lipase immunoreactivity, and α1-proteinase inhibitor concentrations differed significantly between dogs with PLE and FRD. Most initial biomarker concentrations were not predictive of survival time in dogs with PLE.

OBJECTIVE: The objective of this study was to evaluate the oxidative- inflammatory status and iron indices in patients undergoing maintenance hemodialysis (HD with serum ferritin lower than 500ng/mL, and to correlate them with nutritional status. METHOD: In a cross-sectional survey 35 HD patients (23 with normal nutritional status, 12 with Protein-Energy-Wasting syndrome, PEW, and healthy volunteers (n = 35 were studied. Serum concentration of iron, ferritin, transferrin saturation, malondialdehyde (MDA, protein carbonyl (PC, high-sensitive serum C -reactive protein (hs-CRP and blood counts were determined. The nutritional status was determined by anthropometric and biochemical criteria. RESULTS: HD patients showed low values of hemoglobin and higher values of ferritin, MDA and PC when compared with healthy volunteers. HD subjects with PEW had higher values of PC and hs-PCR as compared to HD patients with normal nutritional status. A multiple logistic regression analysis showed that the independent variables PC (Wald Statistic 4.25, p = 0.039 and hs-CRP (Wald Statistic 4.83, p = 0.028 where related with the patients' nutritional condition. CONCLUSION: In HD patients with serum ferritin below 500 ng/mL was observed one association of the markers of oxidative stress and inflammation with poor nutritional status independently of serum ferritin, gender and age.

    Progranulin, a protein secreted from the airway epithelium, is known to attenuate the downstream cascade of neutrophilic inflammation in particular. We hypothesized that progranulin may have a role in inflammatory regulation in asthma. To investigate the association between serum progranulin levels and various clinical features in patients with asthma. Serum samples and clinical data of 475 patients with asthma and 35 healthy controls at a tertiary referral hospital and its affiliated health promotion center were collected. Serum progranulin levels were compared between patients with asthma and healthy controls and then were compared within the patients with asthma in terms of pulmonary function and measures of inflammatory status. Univariate and multivariate analyses were performed to identify factors associated with severity of asthma. Serum progranulin levels were significantly lower in the asthma group than in healthy group and were positively correlated with prebronchodilator forced expiratory volume in 1 second predicted within patients with asthma. We found a negative correlation between serum progranulin levels and blood neutrophil counts. Multivariate analysis revealed that higher serum progranulin levels were associated with a lower risk of severe asthma (odds ratio, 0.888; 95% confidence interval, 0.846-0.932; P progranulin remains unknown, we suggest that serum progranulin may be an indicator of severe asthma with airflow limitation. Future studies with comprehensive airway sampling strategies are warranted to clarify its role, particularly in neutrophilic asthma. Copyright © 2016 American College of Allergy, Asthma & Immunology.

    A well-balanced diet is the first-line treatment in hyperlipidemia. The objective was to study the association between serum phytosterols and dietary patterns to use them as surrogate markers of dietary compliance in primary dyslipidemias. 288 patients with primary hyperlipidemias (192 autosomal dominant hypercholesterolemia (ADH) and 96 familial combined hyperlipidemia (FCHL)) were included. Principal factor analysis identified 2 major dietary patterns using a 137-item food frequency questionnaire. "Vegetable & Fruits pattern" was characterized by higher intake of fruits, green beans, nuts, tomatoes, roasted or boiled potatoes, lettuce and chard and lower of processed baked goods, pizza and beer. "Western pattern" was positively characterized by hamburgers, pasta, sunflower oil, rice, chickpeas, whole milk, veal, red beans and negatively with white fish. Serum non-cholesterol sterols were determined by HPLC-MS/MS. Plant sterols to-total cholesterol (TC) levels were lower with a higher adherence to a "Vegetable & Fruits pattern" (P = 0.009), mainly in ADH subjects (R(2) = 0.019). Their concentration was greater with higher compliance to "Western pattern" especially in FCHL (P = 0.014). Higher levels of synthesis markers-to-TC with a greater adherence to "Vegetable & Fruits pattern" were found (P = 0.001) (R(2) = 0.033 and R(2) = 0.109 in ADH and FCHL respectively). In subjects with primary dislipidemia, dietary patterns associate with serum absorption and synthesis markers, but no with lipid concentrations. The influence of diet on non-cholesterol sterols levels is not powerful enough to use them as subrogate markers.

    Patients with acute ischemic stroke (AIS) frequently experience low free triiodothyronine (fT3) concentrations. Inflammation is recognized as a key contributor to the pathophysiology of stroke. Previous studies, however, did not simultaneously evaluate fT3 and inflammation biomarkers in AIS patients. Markers of inflammation, including serum concentrations of C-reactive protein (CRP) and albumin, and fT3 were assessed retrospectively in 117 patients. Stroke severity was measured on the National Institutes of Health Stroke Scale (NIHSS). Regression analyses were performed to adjust for confounders. Serum fT3 concentrations were significantly lower in moderate AIS patients than those in mild AIS patients (P<0.001). fT3 concentration also positively correlated with serum albumin concentration (r=0.358, P<0.001) and negatively correlated with log10CRP concentration (r=-0.341, P<0.001), NIHSS score (r=-0.384, P<0.001). Multiple regression analysis showed that CRP, albumin concentrations and NIHSS score were independently correlated with fT3 concentration. Binary logistic regression analysis showed that fT3 concentration was an independent factor correlated with NIHSS score, the area under the receiver operating characteristic curve was 0.712 (95% CI, 0.618-0.805). Low fT3 concentrations may be involved in the pathogenic pathway linking inflammation to stroke severity in AIS patients. Copyright © 2016 Elsevier B.V. All rights reserved.

    The chaperone to Zn-Cu superoxide dismutase (CCS) has been postulated as a candidate copper indicator, changing in a consistent manner in induced and recovered copper deficiency, in experimental cell and animal models. In real life people have various conditions that may modify molecules acting as acute phase proteins, such as serum ceruloplasmin and copper concentration and could alter CCS responses. With the hypothesis that CCS mRNA transcripts and protein would be different in individuals suffering inflammatory processes in comparison to healthy individuals, we assessed adult individuals who, although not ill had conditions known to induce variable degrees of inflammation. Screening of 600 adults resulted in two study groups, formed on the basis of their clinical history and levels of serum C reactive protein (CRP): Group 1 (n = 61, mean (range) CRP = 0.9 (0.3-2.0 mg/dL) and Group 2 (n = 150, mean (range) CRP = 6.1 (4.3-8.7 mg/dL). Results showed that mRNA transcripts relative abundance was not different for CCS, MTIIA, TNF-alpha and Cu-Zn-SOD by group (p > 0.05, one way Anova), nor between sexes (p > 0.05, one way Anova). Distribution of CCS mRNA transcripts and CCS protein in serum did not show any differences or trends. Results disproved our hypothesis that CCS abundance of transcripts and CCS protein would be different in individuals suffering inflammatory processes, adding further support to the idea that CCS may be a copper marker.

    OBJECTIVE Progranulin has recently been introduced as a novel adipokine inducing insulin resistance and obesity. In the current study, we investigated renal elimination, as well as association of the adipokine with markers of the metabolic syndrome. RESEARCH DESIGN AND METHODS Progranulin serum levels were quantified by enzyme-linked immunosorbent assay and correlated to anthropometric and biochemical parameters of renal function and glucose and lipid metabolism, as well as inflammation, in 532 patients with stages 1–5 of chronic kidney disease (CKD). RESULTS Median serum progranulin levels adjusted for age, sex, and BMI were significantly different between CKD stages with highest values detectable in stage 5 (stage 1, 58.3 µg/L; stage 2, 63.0 µg/L; stage 3, 65.4 µg/L; stage 4, 68.8 µg/L; and stage 5, 90.6 µg/L). Furthermore, CKD stage was the strongest independent predictor of circulating progranulin in our cohort. In addition, high-sensitivity interleukin-6 and adiponectin remained significantly and independently correlated with the adipokine. CONCLUSIONS We demonstrate that progranulin serum levels increase with deteriorating renal function. These findings are in accordance with the hypothesis that renal clearance is a major elimination route for circulating progranulin. Furthermore, the adipokine is positively and independently associated with markers of inflammation and adiponectin. PMID:23033238

In obese patients, the decrease in the Adiponectin gene (ADIPOQ expression has been associated with a systemic low-grade inflammatory state. Our aim was to investigate the relationship between ADIPOQ +45T>G gene simple nucleotide polymorphism (SNP rs2241766 with serum adiponectin (sAdiponectin, distribution of body fat storage, and inflammation markers.Subjects and methods: In this cross-sectional study, 242 individuals from Western Mexico characterized as Mexican-Mestizo and classified by body mass index (BMI, were included. Anthropometrics, body composition, body fat distribution, and inflammation markers were measured by routine methods. Genotypes were characterized using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP technique and sAdiponectin by the ELISA method. A P-value <0.05 was considered the statistically significant threshold.Results: sAdiponectin is associated with BMI (P < 0.001 and the genotypes (P < 0.001 to 0.0046 GG (8169 ± 1162 ng/mL, TG (5189 ± 501 ng/mL, and TT (3741 ± 323 ng/mL, but the SNP ADIPOQ +45T.G is not associated with BMI. However, the detailed analysis showed association of this SNP with a pattern of fat distribution and correlations (P < 0.05 with inflammation markers and

    This study evaluated the association of vitamin D and bone markers with the development osteoporosis in Palestinian postmenopausal women. Even though vitamin D deficiency was very high for the recruited subjects, it was not associated with osteoporosis except for bones of the hip. Age and obesity were the strongest determining factors of the disease. The purpose of this study was to investigate the association of bone mineral density (BMD) with serum vitamin D levels, parathyroid hormone (PTH), calcium, obesity, and bone turnover markers in Palestinian postmenopausal women. Three hundred eighty-two postmenopausal women (≥45 years) were recruited from various women clinics for BMD assessment (131 women had osteoporosis and 251 were normal and served as controls). Blood samples were obtained for serum calcium, PTH, 25(OH)D, bone formation (N-terminal propeptide (PINP)), and bone resorption (serum C-terminal telopeptide of type I collagen (CTX1)) markers. Women with osteoporosis had statistically significant lower mean weight, height, body mass index (BMI), and serum calcium (p osteoporosis decreased with increasing BMI (overweight OR = 0.11, p = 0.053; obese OR = 0.05, p = 0.007). There was no direct correlation between BMD and PTH, bone turnover markers, and vitamin D except at the lumbar spine. A negative correlation between BMD and age and a positive correlation with BMI were observed. The protective effect of obesity on osteoporosis was complicated by the effect of obesity on vitamin D and PTH.

    Objective: To investigate the diagnostic value of combined detection of serum tumor markers, including CEA, CA125, neuron-specific enolase (NSE) and cytokeratin fragment antigen 21-1 (CYFRA21-1) for lung cancer patients. Methods: The subjects involved 138 diagnosed lung cancer patients (82 males, 56 females, average age 58.6 years, from October 2010 to March 2012), 96 patients with benign lung diseases (56 males, 40 females, average age 51.3 years) and 45 healthy adults (30 males, 15 females, average age 43.9 years). The pathological types of lung cancer consisted of 66 squamous cell carcinoma (SCC), 52 adenocarcinoma and 20 small cell lung cancer (SCLC). The serum levels of CEA, CA125, NSE and CYFRA21-1 were measured with electrochemiluminescence immunoassay. The diagnostic efficacy for different pathological types was compared among each single tumor marker and combination of tumor markers. One-way analysis of variance q test were used for statistical analysis. Results: The serum levels of CEA, CA125, NSE and CYFRA21-1 in patients with lung cancer were higher than those in patients with benign lung diseases and in healthy subjects (CEA: (19.99±30.99), (10.78±19.77), (3.25±3.42) μg/L; CA125: (79.70±95.98), (44.96±44.97), (20.66±7.13) μg/L; NSE: (35.23±40.22), (15.31±8.42), (13.30±5.65) μg/L; CYFRA21-1: (18.07±43.71), (8.30±8.83), (3.13±1.60) μg/L; F=4.481, 5.436, 4.776, 6.002, all P<0.05). The highest level of CEA, NSE or CYFRA21-1 were found in adenocarcinoma (F=4.932, P<0.05), SCLC (F=5.119, P<0.05) or SCC (F=5.378, P<0.05), respectively. The highest sensitivity tumor markers for SCC, SCLC and adenocarcinoma were CYFRA21-1 (78.8%, 52/66), NSE (75.0%, 15/20) and CEA (57.7%, 30/52), respectively. In combined detection, the highest sensitivity combinations for SCC, SCLC and adenocarcinoma were CEA + CYFRA21-1 + NSE (89.4%, 59/66), CEA + CYFRA21-1 + NSE (80.0%, 16/20) and CEA + CA125 + NSE (78.8%, 41/52), respectively. Conclusions: Combined detection

    Currently known prognostic serum biomarkers of melanoma are powerful in metastatic disease, but weak in early-stage patients. This study was aimed to identify new prognostic biomarkers of melanoma by serum mass spectrometry (MS) proteomic profiling, and to validate candidates compared with established markers. Two independent sets of serum samples from 596 melanoma patients were investigated. The first set (stage I = 102; stage IV = 95) was analyzed by matrix assisted laser desorption and ionization time of flight (MALDI TOF) MS for biomarkers differentiating between stage I and IV. In the second set (stage I = 98; stage II = 91; stage III = 87; stage IV = 103), the serum concentrations of the candidate marker serum amyloid A (SAA) and the known biomarkers S100B, lactate dehydrogenase, and C reactive protein (CRP) were measured using immunoassays. MALDI TOF MS revealed a peak at m/z 11.680 differentiating between stage I and IV, which could be identified as SAA. High peak intensities at m/z 11.680 correlated with poor survival. In univariate analysis, SAA was a strong prognostic marker in stage I to III (P = .043) and stage IV (P = .000083) patients. Combination of SAA and CRP increased the prognostic impact to P = .011 in early-stage (I to III) patients. Multivariate analysis revealed sex, stage, tumor load, S100B, SAA, and CRP as independent prognostic factors, with an interaction between SAA and CRP. In stage I to III patients, SAA combined with CRP was superior to S100B in predicting patients' progression-free and overall survival. SAA combined with CRP might be used as prognostic serological biomarkers in early-stage melanoma patients, helping to discriminate low-risk patients from high-risk patients needing adjuvant treatment.

    Ankylosing spondylitis (AS) is a chronic inflammation of the spine and the sacroiliac joints. Current markers of inflammation, such as C-reactive protein (CRP), are reflecting the production of an acute phase reactant rather than tissue specific inflammation, but the use of CRP as a diagnostic...... and prognostic marker for AS has not provided the sought accuracy and specificity. We hypothesized that local enzymatic activity in the disease-affected tissue, which is associated with extensive tissue turnover may, by cleavage, modify the CRP produced in the liver. These cleavage products may provide...

    Full Text Available Introduction. The relationships of the biochemical components in seminal plasma and serum, and their origins and physiological effects in male reproductive system have been poorly understood. Methods. Based on the calibration and quality control measures, 26 biochemical markers, in seminal plasma and serum samples from 36 male infertility patients with nonazoospermia were detected and compared. Results. Only PA was undetectable in all seminal plasma samples. There were significant differences of all other 24 biochemical markers in seminal plasma and serum (P<0.05 except for UA (P=0.214. There were rich proteins in seminal plasma, and globulin accounted for about 90%. There were also abundant enzymes in seminal plasma, and the activities of ALT, AST, AKP, GGT, LDH, CK, and αHBDH in seminal plasma were significantly higher than those in serum while ADA was inversely lower. There were relatively low levels of Glu, TG, TC, and hsCRP in seminal plasma, but Glu was undetectable in 8 of 36 cases. Conclusions. The differences of the levels of biochemical markers in seminal plasma and serum might be associated with the selective secretion of testis, epididymis and male accessory glands, and the specific environment needed for sperm metabolism and function maintenance.

    Full Text Available Background: Inflammation plays a major role in the development and progression of atherosclerosis and coronary artery disease (CAD. Inflammation markers, including white blood cell (WBC count, C-reactive protein (CRP and interleukin-6 (IL-6, are widely used for cardiovascular risk prediction. The aim of the study was to establish factors associated with WBC, CRP and IL-6 in patients with CAD. Two functional polymorphisms in genes encoding enzymes participating in adenosine metabolism were analyzed (C34T AMPD1, G22A ADA. Methods: Plasma concentrations of IL-6 were measured using high-sensitivity ELISA kits, and the nephelometric method was used for high-sensitivity CRP (hs-CRP measurement in 167 CAD patients. Results: Presence of metabolic syndrome (MS and its components, presence of heart failure, severity of CAD symptoms, severe past ventricular arrhythmia (sustained ventricular tachycardia [sVT] or ventricular fibrillation [VF], lower left ventricle ejection fraction, higher left ventricle mass index, higher end-diastolic volume and higher number of smoking pack-years were significantly associated with higher WBC, CRP and IL-6. Strong associations with arrhythmia were observed for IL-6 (median 3.90 vs 1.89 pg/mL, p<0.00001 and CRP concentration (6.32 vs 1.47 mg/L, p=0.00009, while MS was associated most strongly with IL-6. CRP and IL-6 were independent markers discriminating patients with sVT or VF. There were no associations between AMPD1 or ADA genotypes and inflammation markers. Conclusions: WBC, CRP and IL-6 are strongly associated with components of the metabolic syndrome. Their strong association with life-threatening ventricular arrhythmia emphasizes the proarrhythmic role of inflammation in the increased cardiovascular risk of CAD patients.

    Tartrate-resistant phosphatase isoform 5a is expressed in tumor-associated macrophages and is a biomarker of chronic inflammation. Herein, we correlated serum tartrate-resistant phosphatase isoform 5a levels with metabolic syndrome status and made comparisons with traditional markers of inflammation, including c-reactive protein and interleukin-6. One hundred healthy volunteers were randomly selected, and cut-off points for metabolic syndrome related inflammatory biomarkers were determined using receiver operating characteristic curves. Linear and logistic regression models were subsequently used to correlate inflammatory markers with the risk of metabolic syndrome. Twenty-two participants met the criteria for metabolic syndrome, and serum tartrate-resistant phosphatase isoform 5a levels of >5.8 μg/L were associated with metabolic syndrome (c-statistics, 0.730; p = 0.001; 95% confidence interval, 0.618-0.842). In addition, 1 μg/L increases in tartrate-resistant phosphatase isoform 5a levels were indicative of a 1.860 fold increase in the risk of metabolic syndrome (p = 0.012). Elevated serum tartrate-resistant phosphatase isoform 5a levels are associated with the risk of metabolic syndrome, with a cut-off level of 5.8 μg/L.

    The host inflammatory response has a vital role in carcinogenesis and tumour progression. We examined the prognostic value of inflammatory markers (albumin, white-cell count and its components, and platelets) in pre-treated patients with advanced renal cell carcinoma (RCC). Using data from a randomised trial, multivariable proportional hazards models were generated to examine the impact of inflammatory markers and established prognostic factors (performance status, calcium, and haemoglobin) on overall survival (OS). We evaluated a new prognostic classification incorporating additional information from inflammatory markers. Of the 416 patients, 362 were included in the analysis. Elevated neutrophil counts, elevated platelet counts, and a high neutrophil-lymphocyte ratio were significant independent predictors for shorter OS in a model with established prognostic factors. The addition of inflammatory markers improves the discriminatory value of the prognostic classification as compared with established factors alone (C-statistic 0.673 vs 0.654, P=0.002 for the difference), with 25.8% (P=0.004) of patients more appropriately classified using the new classification. Markers of systemic inflammation contribute significantly to prognostic classification in addition to established factors for pre-treated patients with advanced RCC. Upon validation of these data in independent studies, stratification of patients using these markers in future clinical trials is recommended.

    Full Text Available Cushing's syndrome (CS increases cardiovascular risk (CVR and adipocytokine imbalance, associated with an increased inflammatory state. Telomere length (TL shortening is a novel CVR marker, associated with inflammation biomarkers. We hypothesized that inflammatory state and higher CVR in CS might be related to TL shortening, as observed in premature aging.To evaluate relationships between TL, CVR and inflammation markers in CS.In a cross-sectional study, 77 patients with CS (14 males, 59 pituitary-, 17 adrenal- and 1 ectopic-origin; 21 active disease and 77 age-, gender-, smoking-matched controls were included. Total white blood cell TL was measured by TRF-Southern technique. Clinical data and blood samples were collected (lipids, adrenal function, glucose. Adiponectin, interleukin-6 (IL6 and C-reactive protein (CRP were available in a subgroup of patients (n=32. Correlations between TL and clinical features were examined and multiple linear regression analysis was performed to investigate potential predictors of TL.Dyslipidemic CS had shorter TL than non-dyslipidemic subjects (7328±1274 vs 7957±1137 bp, p<0.05. After adjustment for age and body mass index, cured and active CS dyslipidemic patients had shorter TL than non-dyslipidemic CS (cured: 7187±1309 vs 7868±1104; active: 7203±1262 vs 8615±1056, respectively, p<0.05. Total cholesterol and triglycerides negatively correlated with TL (r-0.279 and -0.259, respectively, p<0.05, as well as CRP and IL6 (r-0.412 and -0.441, respectively, p<0.05. No difference in TL according the presence of other individual CVR factors (hypertension, diabetes mellitus, obesity were observed in CS or in the control group. Additional TL shortening was observed in dyslipidemic obese patients who were also hypertensive, compared to those with two or less CVR factors (6956±1280 vs 7860±1180, respectively, p<0.001. Age and dyslipidemia were independent negative predictors of TL.TL is shortened in dyslipidemic CS

    Background: Cocoa flavanols have strong anti-inflammatory properties in vitro. If these also occur in vivo, cocoa consumption may contribute to the prevention or treatment of diseases mediated by chronic inflammation. This critical review judged the evidence for such effects occurring after cocoa consumption. Methods: A literature search in Medline was performed for randomized controlled trials (RCTs) that investigated the effects of cocoa consumption on inflammatory biomarkers. Results: Thirty-three RCTs were included, along with 9 bolus and 24 regular consumption studies. Acute cocoa consumption decreased adhesion molecules and 4-series leukotrienes in serum, nuclear factor κB activation in leukocytes, and the expression of CD62P and CD11b on monocytes and neutrophils. In healthy subjects and in patients with cardiovascular diseases, most regular consumption trials did not find any changes except for a decreased number of endothelial microparticles, but several cellular and humoral inflammation markers decreased in patients suffering from type 2 diabetes and impaired fasting glucose. Conclusions: Little evidence exists that consumption of cocoa-rich food may reduce inflammation, probably by lowering the activation of monocytes and neutrophils. The efficacy seems to depend on the extent of the basal inflammatory burden. Further well-designed RCTs with inflammation as the primary outcome are needed, focusing on specific markers of leukocyte activation and considering endothelial microparticles as marker of vascular inflammation.

A literature search in Medline was performed for randomized controlled trials (RCTs) that investigated the effects of cocoa consumption on inflammatory biomarkers. Thirty-three RCTs were included, along with 9 bolus and 24 regular consumption studies. Acute cocoa consumption decreased adhesion molecules and 4-series leukotrienes in serum, nuclear factor κB activation in leukocytes, and the expression of CD62P and CD11b on monocytes and neutrophils. In healthy subjects and in patients with cardiovascular diseases, most regular consumption trials did not find any changes except for a decreased number of endothelial microparticles, but several cellular and humoral inflammation markers decreased in patients suffering from type 2 diabetes and impaired fasting glucose. Little evidence exists that consumption of cocoa-rich food may reduce inflammation, probably by lowering the activation of monocytes and neutrophils. The efficacy seems to depend on the extent of the basal inflammatory burden. Further well-designed RCTs with inflammation as the primary outcome are needed, focusing on specific markers of leukocyte activation and considering endothelial microparticles as marker of vascular inflammation.

    Full Text Available We examined if two different dietary interventions affected markers of soreness and inflammation over a 5-day high-volume resistance training protocol in females that resistance-trained 8 weeks prior. Twenty-eight females (age: 20 ± 1 yr; body mass: 63.5 ± 1.6 kg, height: 1.67 ± 0.01 m completed 4 weeks of pre-training (weeks 1-4 followed by a subsequent 4-week training period along with a dietary intervention (weeks 5-8. Dietary interventions from weeks 5-8 included: a no intervention (CTL, n = 10 b a higher-protein diet supplemented with hydrolyzed whey protein (50 g/d and omega-3 fatty acids (900 mg/d (DI, n = 8, and c the DI condition as well as creatine monohydrate (5 g/d (DI+C, n = 10. During week 9, participants resistance-trained for five consecutive days whereby 8 sets of 10 target repetitions at 70% one repetition maximum (1RM were performed each day for bench press, back squat, deadlift, and hip-thrusters with the intent of eliciting muscle soreness and inflammation. Prior to and 24 h following each of the 5 bouts muscle soreness (DOMS was assessed via questionnaire, and fasting blood was obtained and analyzed for serum cortisol, interleukin-6 (IL-6 and C-reactive protein (CRP. No group*time (G*T or time effects were observed for training volume over the 5-d overreaching protocol. Furthermore, no group*time (G*T or time effects were observed for serum cortisol, IL-6 or CRP, and DOMS actually decreased in all groups 24 h following the fifth day training bout. This study demonstrates that, regardless of protein, omega-3 fatty acid and/or creatine supplementation, 5 days of consecutive resistance training does not alter perceived muscle soreness, training volume, and/or markers of inflammation in novice resistance-trained females.

    The aim of this study was to determine the clinical performances of noninvasive serum markers for the prediction of liver fibrosis in chronic viral liver diseases. We analyzed a total of 225 patients with chronic viral liver diseases (180 with hepatitis B virus, 43 with hepatitis C virus, and 2 with hepatitis B+C virus) who underwent a liver biopsy procedure at the Hanyang University Guri Hospital between March 2002 and February 2007. Serum was also obtained at the time of liver biopsy. Liver fibrosis was staged according to the scoring system proposed by the Korean Study Group for the Pathology of Digestive Diseases. Various noninvasive serum markers were evaluated, including the aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AAR), age-platelet (AP) index, AST/platelet ratio index (APRI), cirrhosis discriminant score (CDS), platelet count, hyaluronic acid (HA), and type IV collagen. There were 17, 40, 61, 74, and 33 patients at stages F0, F1, F2, F3, and F4, respectively. The overall diagnostic accuracies of each marker, as determined by the area under receiver operating characteristics curves, were APRI=0.822, CDS=0.776, platelet count=0.773, AP index=0.756, HA=0.749, type IV collagen=0.718, and AAR=0.642 for predicting significant fibrosis (> or =F2); and CDS=0.835, platelet count=0.795, AP index=0.794, HA=0.766, AAR=0.711, type IV collagen=0.697, and APRI=0.691 for predicting extensive fibrosis (> or =F3). All noninvasive serum markers evaluated in this study were useful for predicting significant or extensive liver fibrosis in chronic viral liver diseases. In particular, APRI was most useful for the prediction of significant fibrosis, and CDS was most useful for the prediction of extensive fibrosis.

    Objective: To study the clinical significance of determination of serum fibrosis markers in patients with pulmonary tuberculosis. Methods: Serum hyaluronic acid (HA), laminin (LN), procollagen III peptide (P III P) and Type IV collagen (IV C) contents were determined with RIA in 128 patients with pulmonary tuberculosis both before and after treatment as well as in 40 controls. Results: Before treatment, the serum contents of the four markers in the patients were significantly higher than those in the controls (P 0.05). Decreases of the levels in treatment failures were not significant and the levels remained significantly higher than those in controls (P<0.01 or P<0.05). Conclusion: Determination of serum fibrosis markers levels in patients with pulmonary tuberculosis is valuable for early diagnosis as well as for evaluation of the effect of chemotherapy. (authors)

    Full Text Available BackgroundProgression of liver fibrosis is characterized by synthesis and degradation of extracellular matrix (ECM. Matrix-metalloproteinases (MMP cleave collagen fibers at a specific site and thereby generate soluble fragments of ECM (neo-epitopes. The levels of these neo-epitopes might reflect the stage of liver fibrosis and may allow monitoring of anti-fibrotic therapies. Here we analyzed these neo-epitopes as read-out for a liver directed therapy with statins.MethodsBile duct ligation (BDL was performed on wildtype rats, which received atorvastatin (15mg/kg*d for one week starting at one, two, three, four and five weeks after BDL (T1-T5, while controls remained untreated. Hepatic fibrosis was analyzed by immunohistochemistry and hepatic hydroxyproline content. TGFβ levels were measured by RT-PCR. Proteolytic activity of MMP-2 was examined by zymography. Levels of degradation MMP driven type I, III, IV and VI collagen degradation (C1M, C3M, C4M and C6M and type III and IV collagen formation (PRO-C3 and P4NP7S markers were assessed by specific ELISAs in serum probes.ResultsSerum markers of ECM neo-epitopes reflected significantly the deposition of ECM in the liver and were able to distinguish between early (T1-T3 and severe fibrosis (T4-T5. Statin treatment to the fibrotic livers resulted in reduction of neo-epitope markers, especially when therapy was started in the stage of severe fibrosis (T4-T5. Furthermore, these markers correlated with hepatic expression of profibrotic cytokines TGFβ1 and TGFβ2. Formation markers of type III and IV collagen (PRO-C3 and P4NP7S and degradation markers C4M and C6M correlated significantly with MMP-2 activity in rats with severe fibrosis. ConclusionDetermination of ECM remodelling turnover markers in serum allowed a distinction between mild and severe fibrosis. With respect to statin therapy, the markers may serve as read-out for efficacy of anti-fibrotic treatment.

    Screening indexes of tumor serum markers for benign and malignant solitary pulmonary nodules (SPNs) were analyzed to find the optimum method for diagnosis. Enzyme-linked immunosorbent assays, an automatic immune analyzer and radioimmunoassay methods were used to examine the levels of 8 serum markers in 164 SPN patients, and the sensitivity for differential diagnosis of malignant or benign SPN was compared for detection using a single plasma marker or a combination of markers. The results for serological indicators that closely relate to benign and malignant SPNs were screened using the Fisher discriminant analysis and a non-conditional logistic regression analysis method, respectively. The results were then verified by the k-means clustering analysis method. The sensitivity when using a combination of serum markers to detect SPN was higher than that using a single marker. By Fisher discriminant analysis, cytokeratin 19 fragments (CYFRA21-1), carbohydrate antigen 125 (CA125), squamous cell carcinoma antigen (SCC) and breast cancer antigen (CA153), which relate to the benign and malignant SPNs, were screened. Through non-conditional logistic regression analysis, CYFRA21-1, SCC and CA153 were obtained. Using the k-means clustering analysis, the cophenetic correlation coefficient (0.940) obtained by the Fisher discriminant analysis was higher than that obtained with logistic regression analysis (0.875). This study indicated that the Fisher discriminant analysis functioned better in screening out serum markers to recognize the benign and malignant SPN. The combined detection of CYFRA21-1, CA125, SCC and CA153 is an effective way to distinguish benign and malignant SPN, and will find an important clinical application in the early diagnosis of SPN. © 2014 S.

    To evaluate the diagnostic value and relationship between five tumor markers (CA19- 9,CA125,CYFRA21-1 ,CEA,NSE) and free DNA in serum for lung cancer detection and try to find a new and more efficient tumor marker, the amounts of CA19-9, CA125, CYFRA21-1, CEA, NSE were determined by RIA and free DNA was determined by the use of quantitative real time PCR amplification of the human epidermal growth factor receptor (EGFR) in 52 lung cancer patients and 8 cases of benign pulmonary disease and 10 healthy controls. The resulls showed that average concentration of free DNA in serum of lung cancer patients, benign pulmo- nary disease and healthy controls was 107.6ng/mL, 76.86ng/mL and 18.8ng/mL, respective- ly. The diagnostic sensitivity, specificity and accuracy of free DNA for lung cancer were 71. 2%, 50% and 68.3%, same as the diagnostic value of combined detection of five tumor markers. The sensitivity, specificity and accuracy of the five tumor markers and free DNA combinend detection for lung cancer were 94.2%, 25% and 85%, respectively. The free DNA in the serum of lung cancer patients may be a new and better tumor marker. (authors)

    Full Text Available Skeletal muscles in patients with cancer undergo many changes due to immuno-inflammatory factors of tumor origin, or to chemotherapy and irradiation. Aim of the present study is to identify serological biomarkers and early myopathic features in skeletal muscle biopsies from weight stable patients bearing colorectal cancer at the onset of disease. Morphometric analyses by histochemistry and immunohistochemistry were performed on intraoperative muscle biopsies from patients with early colorectal cancer and from weight stable patients undergoing surgery for benign non-inflammatory conditions. Serological analyses for testing markers of inflammation (C Reactive Protein, CRP, muscle enzymes, (Creatin Kinase, CK, soluble isoforms of adhesion molecules (Neural Cell Adhesion Molecule, NCAM, and a marker of protein turnover (prealbumin, a typical indicator of caloric and protein malnutrition were also performed. Fifty oncologic patients (28 male/22 female and 25 non oncologic patients (18 male/7 female (p=N.S. were studied. In muscles from cancer patients we observed a subclinical myopathy characterized by an abnormal distribution of myonuclei. The percentage of myofibers with internalized nuclei was significantly higher in oncologic (median= 13.1%, IQR= 6.0-20.3 than in non oncologic patients (median= 3%, IQR= 2.5-6.1 (p<0.0001. The frequency of these internally nucleated myofibers is even higher in a subgroup of oncologic patients taking myotoxic drugs. In cancer patients, we observed an inverse correlation between the number of internally nucleated fibers and the presence of node metastasis (N+ (ρ=-0.30 (p=0.03. Moreover, in patients with colorectal cancer, low serum levels of preoperative prealbumin (median= 167,7 mg/L, normal range 200-400 mg/L, were detected. The link between the observed early myopathy and long-term cachexia is supported also by the altered expression of sarcolemma associated proteins, in particular laminin and dystrophin

    This study aimed to evaluate associations between exposure to a group of persistent organic pollutants, measured in both adipose tissue and serum samples from breast cancer patients, and a set of tumor prognostic markers. The study population comprised 103 breast cancer patients recruited in Granada, Southern Spain. Data for tumor prognostic markers were retrieved from hospital clinical records and socio-demographic information was gathered by questionnaire. Persistent organic pollutants were quantified by gas chromatography with electron capture detection. Exposure levels were categorized in quartiles, and associations were evaluated using unconditional logistic regression. Adipose tissue HCB concentrations were associated positively with ER and PR expression (p-trends = 0.044 and 0.005, respectively) and negatively with E-Cadherin and p53 expression (p-trends = 0.012 and 0.027, respectively). PCB-180 adipose tissue concentrations were positively associated with HER2 expression (p-trend = 0.036). Serum PCB-138 concentrations were positively associated with ER and PR expression (p-trends = 0.052 and 0.042, respectively). The risk of p53 expression was higher among women in the lowest quartile of serum PCB-138 concentrations, but no significant trend was observed (p-trend = 0.161). These findings indicate that human exposure to certain persistent organic pollutants might be related to breast cancer aggressiveness. We also highlight the influence on exposure assessment of the biological matrix selected, given that both serum and adipose tissue might yield relevant information on breast cancer prognosis. - Highlights: • The role of POP exposure on the pathogenesis breast cancer is still controversial. • POPs were analyzed in serum and adipose tissue from breast cancer patients. • POP concentrations were associated with breast cancer prognostic markers. • POPs in serum and adipose tissue of breast cancer patients may provide different clues.

    To evaluate blood and serum markers in traumatic spinal cord injured (SCI) patients, with and without pressure sores. This cross-sectional study was performed at the Ministry of Health Diskapi Yildirim Beyazit, and Numune Education and Research Hospitals, Ankara, Turkey, from 2006-2008. A total of 23 SCI patients with pressure sores (group I) and a control group of 25 SCI patients without pressure sores (group II) were evaluated. Characteristics of sores were examined with respect to duration, location, grade, tissue types, surface area, and exudate amount. Recorded laboratory parameters included erythrocyte sedimentation rates (ESR), C-reactive protein (CRP), hemoglobin (Hb), hematocrit (Htc), lymphocytes, white blood cells (WBC), red blood cells (RBC), serum iron, transferrin, total iron-binding capacity (TIBC), ferritin, total protein, albumin, vitamin B12, and zinc. The most common pressure sore location was the sacrum (38%). Compared to the control group, the patients with pressure sores showed anemia with reduced serum iron, transferrin, TIBC, and increased ferritin. They also had increased ESR, CRP, and WBC and reduced lymphocytes, total protein, albumin and zinc. Statistically significant correlations were found between CRP, Hb, Htc, lymphocytes, RBC, WBC, and serum protein levels, and grade of pressure sores. Clinicians should regularly screen patients with respect to blood and serum markers, in order to determine any risks for pressure sores, and they should perform immediate preventive measures based on the patient's condition.

    2014-01-01

    Background and aims We investigated whether objectively measured sedentary time was associated with markers of inflammation in adults with newly diagnosed type 2 diabetes. Methods and results We studied 285 adults (184 men, 101 women, mean age 59.0 ± 9.7) who had been recruited to the Early ACTivity in Diabetes (Early ACTID) randomised controlled trial. C-reactive protein (CRP), adiponectin, soluble intracellular adhesion molecule-1 (sICAM-1), interleukin-6 (IL-6), and accelerometer-determined sedentary time and moderate-vigorous physical activity (MVPA) were measured at baseline and after six-months. Linear regression analysis was used to investigate the independent cross-sectional and longitudinal associations of sedentary time with markers of inflammation. At baseline, associations between sedentary time and IL-6 were observed in men and women, an association that was attenuated following adjustment for waist circumference. After 6 months of follow-up, sedentary time was reduced by 0.4 ± 1.2 h per day in women, with the change in sedentary time predicting CRP at follow-up. Every hour decrease in sedentary time between baseline and six-months was associated with 24% (1, 48) lower CRP. No changes in sedentary time between baseline and 6 months were seen in men. Conclusions Higher sedentary time is associated with IL-6 in men and women with type 2 diabetes, and reducing sedentary time is associated with improved levels of CRP in women. Interventions to reduce sedentary time may help to reduce inflammation in women with type 2 diabetes. PMID:24925122

  2. Metabolomic profiling reveals mitochondrial-derived lipid biomarkers that drive obesity-associated inflammation.

    Brante P Sampey

    Full Text Available Obesity has reached epidemic proportions worldwide. Several animal models of obesity exist, but studies are lacking that compare traditional lard-based high fat diets (HFD to "Cafeteria diets" (CAF consisting of nutrient poor human junk food. Our previous work demonstrated the rapid and severe obesogenic and inflammatory consequences of CAF compared to HFD including rapid weight gain, markers of Metabolic Syndrome, multi-tissue lipid accumulation, and dramatic inflammation. To identify potential mediators of CAF-induced obesity and Metabolic Syndrome, we used metabolomic analysis to profile serum, muscle, and white adipose from rats fed CAF, HFD, or standard control diets. Principle component analysis identified elevations in clusters of fatty acids and acylcarnitines. These increases in metabolites were associated with systemic mitochondrial dysfunction that paralleled weight gain, physiologic measures of Metabolic Syndrome, and tissue inflammation in CAF-fed rats. Spearman pairwise correlations between metabolites, physiologic, and histologic findings revealed strong correlations between elevated markers of inflammation in CAF-fed animals, measured as crown like structures in adipose, and specifically the pro-inflammatory saturated fatty acids and oxidation intermediates laurate and lauroyl carnitine. Treatment of bone marrow-derived macrophages with lauroyl carnitine polarized macrophages towards the M1 pro-inflammatory phenotype through downregulation of AMPK and secretion of pro-inflammatory cytokines. Results presented herein demonstrate that compared to a traditional HFD model, the CAF diet provides a robust model for diet-induced human obesity, which models Metabolic Syndrome-related mitochondrial dysfunction in serum, muscle, and adipose, along with pro-inflammatory metabolite alterations. These data also suggest that modifying the availability or metabolism of saturated fatty acids may limit the inflammation associated with obesity

    To evaluate the impact of smoking and number of previous births on maternal serum levels of alpha-fetoprotein and free beta-subunit of human chorionic gonadotropin (free beta-hCG). The study included 3,252 completed unaffected singleton pregnancies that proceeded beyond 37 weeks' gestation and resulted with a birth of healthy child. Smoking status of mothers and data concerning gravidity and parity were collected at the sampling date. Serum markers were measured between 13 and 22 gestational weeks, corrected for maternal weight, and converted to multiples of median (MoM) for unaffected pregnancy of the corresponding gestational age. Median MoM values for both markers were examined in relation to both: smoking habits and number of previous births. Smokers had significantly decreased free beta-hCG MoM values compared to nonsmokers (p habits, especially concerning the free beta-hCG levels, would be worthwhile. The evidence of the coexisting influence of parity on serum levels of free beta-hCG, both in smokers and nonsmokers, should perhaps be a stimulus for reconsideration of which corrections the screening performance is dependent on.

    Obstructive sleep apnea syndrome (OSAS) has been indicated to contribute to the development of cardiovascular disease; however, the underlying mechanism remains unclear. This study aimed to test the hypothesis that OSAS may be associated with cardiovascular disease by elevating serum levels of inflammatory markers and causing arterial stiffening and endothelial dysfunction. Related scientific reports published from January 1, 2006, to June 30, 2015, were searched in the following electronic literature databases: PubMed, Excerpta Medica Database, ISI Web of Science, Directory of Open Access Journals, and the Cochrane Library. The association of OSAS with serum levels of inflammatory markers, endothelial dysfunction, and arterial stiffening were investigated. Overall, 18 eligible articles containing 736 patients with OSAS and 424 healthy persons were included in this meta-analysis. Flow-mediated dilation in patients with moderate-severe OSAS was significantly lower than that in controls (standardized mean difference -1.02, 95% CI -1.31 to -0.73, Preactive protein and C-reactive protein (standardized mean difference 0.58, 95% CI 0.42-0.73, P<0.0001) were significantly higher in patients with OSAS than in controls. OSAS, particularly moderate-severe OSAS, appeared to reduce endothelial function, increase arterial stiffness, and cause chronic inflammation, leading to the development of cardiovascular disease. © 2015 The Authors.

    Objective: To study the serum tumor markers, immunoglobulin, TNF-α and hs-CRP in breast cancer in different pathological stages of the concentration, and to analyze the clinical significance of early diagnosis of breast cancer. Methods: A total of 130 patients with breast cancer were divided into stage I, II, III and IV according to clinical pathology. In addition, 40 patients with benign breast disease and 35 healthy subjects were selected as benign breast disease group and control group. Serum tumor markers, immunoglobulins, TNF-αand hs-CRP concentrations were measured and compared of all subjects. Results: There were no significant difference in serum tumor markers, immunoglobulin and inflammatory factors between the control group and the benign breast cancer group. The level of serum tumor markers in breast cancer group was significantly higher than that in control group and benign breast cancer group. The levels of serum CA125, CA153 and CEA were gradually increased with the severity enhancing from stage I and IV of breast cancer, and he difference was statistically significant. The level of serum immunoglobulin in breast cancer group was significantly higher than that in control group and benign breast cancer group. The levels of serum IgG and IgM increased gradually severity enhancing from stage I and IV of breast cancer, and the difference was statistically significant. The level of serum TNF-α and hs-CRP in serum of breast cancer group was significantly higher than that of control group and benign breast cancer group. The serum levels of TNF-α and hs-CRP increased gradually with severity enhancing from stage I and IV of breast cancer, and the difference was statistically significant. Conclusion: The level of serum tumor markers in breast cancer patients is increasing. Humoral and inflammatory responses are activated to varying degrees and increase with the aggregation of disease. They may involve regulating the occurrence and metastasis of breast

    Low organisational justice has been shown to be associated with increased risk of various health problems, but the underlying mechanisms remain unclear. We tested whether organisational injustice contributes to chronic inflammation in a population of middle-aged men and women. This prospective cohort study uses data from 3205 men and 1204 women aged 35-55 years at entry into the Whitehall II study (phase 1, 1985-1988). Organisational justice perceptions were assessed at phase 1 and phase 2 (1989-1990) and circulating inflammatory markers C-reactive protein (CRP) and interleukin (IL)-6 at phase 3 (1991-1993) and phase 7 (2003-2004). In men, low organisational justice was associated with increased CRP levels at both follow-ups (phase 3 and 7) and increased IL-6 at the second follow-up (phase 7). The long term (phase 7) associations were largely independent of covariates, such as age, employment grade, body mass index and depressive symptoms. In women, no relationship was found between organisational justice and CRP or IL-6. This study suggests that organisational injustice is associated with increased long-term levels of inflammatory markers among men.

    Household air pollution (HAP) and human immunodeficiency virus (HIV) are associated with increased risk for chronic obstructive pulmonary disease. Both HAP and HIV are widespread in Sub-Saharan Africa, including Malawi, where HIV has 10.6% prevalence in patients 15-49 years old. We hypothesized that HIV infection (HIV + ) and habitual exposure to HAP (HAP + ) synergize to cause systemic inflammation and vascular injury, which may herald early onset of chronic respiratory diseases. In this pilot study, 50 subjects from Malawi with known HIV status were administered surveys recording demographics, HAP exposure, and respiratory symptoms/diagnoses. Peripheral blood was collected, and Meso Scale Discovery V-Plex assay was used to measure the levels of 41 serum markers. Almost all subjects (96%) reported HAP + , 30 were HIV + , 20 were HIV - , with a mean age of 22 years in both groups. More females (73%) were HIV + , whereas 65% of those who were HIV - were males. The vast majority were never-smokers (70% of HIV - and 83% of HIV + subjects, respectively). Forty-six percent of all subjects (57% of HIV + HAP + and 33% of HIV - HAP + ) reported respiratory diagnoses and/or respiratory symptoms, with breathlessness and cough being most common. Although HIV + HAP + individuals had a trend to increased proinflammatory cytokines and vascular injury markers, and decreases in proangiogenic factors compared with HIV - HAP + , only the decrease in serum interleukin-16 (by 44%) was statistically significant (P = 0.03). Also, compared with other subjects, serum interleukin-2 levels were significantly decreased (by 31%; P = 0.02) in HIV + subjects with persistent respiratory symptoms. This study suggests a high prevalence of respiratory symptoms in HIV + individuals exposed to HAP. The significant decrease in interleukin-2 and interleukin-16, cytokines associated with HIV clearance, may contribute to viral persistence, and because their low levels were found to correlate with

    Cardiovascular disease (CVD) is a major cause of morbidity and mortality in rheumatoid arthritis (RA). There are limited experimental data on vascular involvement in arthritis models. To study the link between CVD and inflammation in RA, we developed a model of vascular dysfunction and articular inflammation by collagen-induced arthritis (CIA) in C57Bl/6 (B6) mice. We studied the expression of vascular inflammatory markers in CIA with and without concomitant hyperlipidic diet (HD). Collagen-induced arthritis was induced with intradermal injection of chicken type-II collagen followed by a boost 21 days later. Mice with and without CIA were fed a standard diet or an HD for 12 weeks starting from the day of the boost. Arthritis severity was evaluated with a validated clinical score. Aortic mRNA levels of vascular cell adhesion molecule-1 (VCAM-1), inducible nitric oxide synthase (iNOS) and interleukin-17 were analysed by quantitative RT-PCR. Vascular cell adhesion molecule-1 localization in the aortic sinus was determined by immunohistochemistry. Atherosclerotic plaque presence was assessed in aortas. Collagen-induced arthritis was associated with increased expression of VCAM-1, independent of diet. VCAM-1 overexpression was detectable as early as 4 weeks after collagen immunization and persisted after 15 weeks. The HD induced atheroma plaque formation and aortic iNOS expression regardless of CIA. Concomitant CIA and HD had no additive effect on atheroma or VCAM-1 or iNOS expression. CIA and an HD diet induced a distinct and independent expression of large-vessel inflammation markers in B6 mice. This model may be relevant for the study of CVD in RA. © 2016 The Authors.

    Lung cancer is by far the leading cause of cancer death in the world. Despite the improvements in diagnostic methods, the status of early detection was not achieved. So, a new diagnostic method is needed. The aim of this study is to obtain the highly specific nucleic acid aptamers with strong affinity to tumor markers in the serum of the lung cancer patients for targeting the serum. Aptamers specifically binding to tumor markers in the serum of the lung cancer patients were screened from the random single-stranded DNA library with agarose beads as supports and the serum as a target by target-substituting subtractive SELEX technique and real-time quantitative polymerase chain reaction technique. Subsequently, the secondary single-stranded DNA library obtained by 10 rounds of screening was amplified to double-stranded DNA, followed by high-throughput genome sequence analysis to screen aptamers with specific affinity to tumor markers in the serum of the lung cancer patients. Finally, six aptamers obtained by 10 rounds of screening were identified with high specific affinity to tumor markers in the serum of the lung cancer patients. Compared with other five aptamers, the aptamer 43 was identified both with the highest specificity to bind target molecule and without any obvious affinity to non-specific proteins. The screened aptamers have relatively high specificity to combine tumor markers in the serum of the lung cancer patients, which provides breakthrough points for early diagnosis and treatment of lung cancer.

    Enteric inflammation models can help researchers' study methods to improve health and performance and evaluate various growth promoters and dietary formulations targeted to improve performance in poultry. Oral administration of fluorescein isothiocyanate-dextran (FITC-d; 3-5 kDa) and its pericellular mucosal epithelial leakage are an established marker to evaluate enteric inflammation in multiple species. The present study evaluated different methods to induce gut inflammation in poultry based on FITC-d leakage. Four independent experiments were completed with different inflammation treatment groups, and serum FITC-d and/or retention of FITC-d in GI tract were determined. In experiment 1 (n = 10 birds/treatment, broilers, processed at 14 days), groups included control (CON), dextran sodium sulfate (DSS; drinking water at 0.75%) and feed restriction (FRS; 24 h before processing). Experiment 2 (n = 14 birds/treatment, leghorns, processed at 7 days) included CON, DSS, FRS, and rye-based diet (RBD). In experiments 3 and 4 (n = 15 birds/treatment, broilers, processed at 7 days), groups were CON, DSS, high fat diet (HFD), FRS, and RBD. In all experiments, FRS and RBD treatments showed significantly higher serum FITC-d levels compared to the respective CON. This indicates that FRS and RBD results in disruption of the intact barrier of the gastrointestinal tract (GIT), resulting in increased gut permeability. DSS and HFD groups showed elevation of serum FITC-d levels although the magnitude of difference from respective CON was inconsistent between experiments. FRS was the only treatment which consistently showed elevated retention of FITC-d in GIT in all experiments. The results from present studies showed that FRS and RBD, based on serum FITC-d levels, can be robust models to induce gut leakage in birds in different age and species/strains.

    Objective: Bone metabolic markers (BMM) are biochemical substances that reflect bone resorption or formation. Some of them have been found to be useful in the diagnosis and management of bone metastases. The aim of this study was to investigate the usefulness of two bone resorption markers: bone-specific alkaline phosphatase (B-ALP) and N-terminal procollagen propeptides of type I collagen (PINP), as well as two bone formation markers: cross linked N and C terminal telepeptides of type I collagen (NTX and CTX) in the detection of bone metastasis in patients with differentiated thyroid cancer (DTC). Methods: There were sixty-three DTC patients in this study, 33 cases with clinically confirmed bone metastases and 30 cases with no bone metastases. The extents of bone metastases (or extents of the disease, EOD) were classified into four grades (0, I, II and III) according to the clinical and imaging findings including 99 Tc m -MDP, 131 I whole body scans and others. Serum BMM levels were measured by chemiluminescence immunoassay for B-ALP, radioimmunoassay for PINP, ELISA for NTX and electrochemiluminescence immunoassay for CTX. Nonparametric Mann-Whitney U test, grade correlation analysis and receiver operator characteristic (ROC) curve were applied to analyze the correlation between BMM and DTC patients with bone metastases. Results: The serum levels of B-ALP, NTX and CTX were significantly higher in DTC patients with bone metastases than those in patients with no bone metastases (all P 0.05). The serum levels of all markers were correlated with EOD grades (r s =0.371-0.558, all P<0.01). B-ALP level was found to have significant difference between EOD 0 to I (P=0.012). The diagnostic sensitivity and specificity of B-ALP for detecting DTC with bone metastases were 71.1% and 76.7% respectively by ROC curve analysis, which were higher than those of the other three markers. Conclusions: Serum BMM levels of B-ALP, NTX and CTX were useful for the evaluation of DTC with

    Previous research demonstrated that social environment can influence progression of atherosclerosis in the Watanabe Heritable Hyperlipidemic (WHHL) rabbit. This study examined the effect of social environment on markers of oxidative stress and inflammation to clarify the physiological pathways potentially responsible for the influence of social environment on disease. WHHL rabbits were assigned to 1 of 3 social groups: an unstable group, in which unfamiliar rabbits were paired daily, with the pairing switched each week; a stable group, in which littermates were paired daily; and an individually-caged group. The stable group engaged in more affiliative social behavior than the unstable group. The unstable group showed more agonistic behavior compared with the stable group and higher C-reactive protein levels than the individually caged group. The individually caged group was behaviorally sedentary, had higher 24-hour urinary catecholamine levels than the other groups, and exhibited higher NAD(P)H-oxidase activity in the aortic arch relative to the stable group. The results suggest that social environment creates distinct behavioral contexts that can affect markers of inflammation and oxidative stress early in the development of atherosclerosis. Specifically, physical inactivity associated with individual caging affects indices of oxidative stress and inflammation. These pathophysiological markers may help to explain behaviorally related differences in the extent of atherosclerosis observed in prior studies.

    Full Text Available Evaluating diagnostic and early detection biomarkers requires comparing serum protein concentrations among biosamples ascertained from subjects with and without cancer. Efforts are generally made to standardize blood processing and storage conditions for cases and controls, but blood sample collection conditions cannot be completely controlled. For example, blood samples from cases are often obtained from persons aware of their diagnoses, and collected after fasting or in surgery, whereas blood samples from some controls may be obtained in different conditions, such as a clinic visit. By measuring the effects of differences in collection conditions on three different markers, we investigated the potential of these effects to bias validation studies.We analyzed serum concentrations of three previously studied putative ovarian cancer serum biomarkers-CA 125, Prolactin and MIF-in healthy women, women with ovarian cancer undergoing gynecologic surgery, women undergoing surgery for benign ovary pathology, and women undergoing surgery with pathologically normal ovaries. For women undergoing surgery, a blood sample was collected either in the clinic 1 to 39 days prior to surgery, or on the day of surgery after anesthesia was administered but prior to the surgical procedure, or both. We found that one marker, prolactin, was dramatically affected by collection conditions, while CA 125 and MIF were unaffected. Prolactin levels were not different between case and control groups after accounting for the conditions of sample collection, suggesting that sample ascertainment could explain some or all of the previously reported results about its potential as a biomarker for ovarian cancer.Biomarker validation studies should use standardized collection conditions, use multiple control groups, and/or collect samples from cases prior to influence of diagnosis whenever feasible to detect and correct for potential biases associated with sample collection.

    Objective: To observe the effect of Ganfukang on liver function and serum hepatic fibrosis markers levels in SD rats with experimental hepatic fibrosis. Methods: SD rat models of liver fibrosis was induced by CCl 4 (n=57). Liver function (GPT, GOT) and serum hepatic fibrosis markers levels (HA, LN, C-IV, PC-III, with RIA) were tested in these models and 10 control rats. Eleven model rats were left untreated, the others were treated with Ganfukang of different concentrations and the above hepatic parameters were again determined after completion of treatment. Results: Lever function was much deteriorated and serum markers levels significantly increased in the model rats (vs controls, P<0.01). After treatment with Ganfukang, the improvement was significant (vs untreated models, P<0.01). Conclusion: Ganfukang is of definite therapeutic value for experimental hepatic fibrosis in rat models.

    Full Text Available We measured the concentrations of several circulating fibrosis markers (type I collagen I, type III procollagen, hyaluronan and eosinophil granule proteins (ECP and EPX in lymphatic filariasis patients to investigate their relationship with clinical, parasitological and immunological data. This study was conducted in Polynesian patients with various stages of the disease (acute lymphangitis, chyluria, hydrocoele, elephantiasis, a closely related microbial lymphangitis and endemic controls. We observed modifications of the different markers in this pathology. Serum type I collagen and PIIINP were decreased. Serum hyaluronan, linked to perilymphatic granulomatous inflammation, was significantly increased in acute lymphangitis and elephantiasis patients. Serum ECP was also increased, at the limit of significance in our sample, in elephantiasis patients. These two last markers, already validated in another helminth disease, schistosomiasis, have potential interest in terms of follow-up of morbidity in these parasitic diseases.

    Full Text Available Treatment with the anti-diabetic drug metformin is followed by a decline in plasma cobalamin, but it is unsettled whether this denotes an impaired cobalamin status. This study has explored changes in the markers of cobalamin status in women with Polycystic Ovary Syndrome treated with metformin (1.5–2.5 g per day (n = 29 or placebo (n = 23 for six months. Serum samples were collected before and after two, four, and six months of treatment. We found serum cobalamin to decline and reach significant lower levels after six months of treatment (p = 0.003. Despite the decline in serum cobalamin, we observed no reductions in the physiological active part of cobalamin bound to transcobalamin (holotranscobalamin, or increase in the metabolic marker of cobalamin status, methylmalonic acid. Instead, the non-functional part of circulating cobalamin bound to haptocorrin declined (p = 0.0009. Our results have two implications: The data questions whether metformin treatment induces an impaired cobalamin status in PCOS patients, and further suggests that serum cobalamin is a futile marker for judging cobalamin status in metformin-treated patients.

    Diesel exhaust (DE) as the major source of vehicle-emitted particle matter in ambient air impairs lung function. The objectives were to assess the contribution of local (eg, the fraction of exhaled nitric oxide [FeNO] and serum Club cell secretory protein [CC16]) and systemic (eg, serum C-reaction protein [CRP] and interleukin-6 [IL-6]) inflammation to DE-induced lung function impairment using a unique cohort of diesel engine testers (DETs, n = 137) and non-DETs (n = 127), made up of current and noncurrent smokers. Urinary metabolites, FeNO, serum markers, and spirometry were assessed. A 19% reduction in CC16 and a 94% increase in CRP were identified in DETs compared with non-DETs (all p values regulatory risk assessment. Local and systemic inflammation may be key processes that contribute to the subsequent development of obstructive lung disease in DE-exposed populations.

    Full Text Available This study aimed to determine if there are differences in inflammatory markers in the acute phase between systolic heart failure and heart failure with preserved systolic function. One hundred and thirty-one patients with acute heart failure were recruited consecutively. At admission, plasma fibrinogen, Creactive protein, sialic acid, von Willebrand factor, vascular endothelial growth factor, interleukin-6 and NTproBNP were all evaluated. If the ejection fraction was 45% or over patients were included in the HF-PSF group; the remaining patients were included in the SHF group. The HF-PSF patients were older (72±10 vs 63±12 years, P<0.001, presented a higher rate of atrial fibrillation (56.1 vs 21.3%, P<0.001, and had a lower rate of hemoglobin (12.2±2 vs 13.3±2.1 g/dL, P<0.01. No significant differences were observed in the inflammation markers analyzed among SHF and HFPSF groups. In the acute phase of heart failure there is a marked elevation of inflammatory markers but there are no differences in the inflammatory markers analyzed between the two different types of heart failure

    Irisin has been proposed to regulate metabolic diseases such as obesity, diabetes or metabolic syndrome which are common comorbidities in psoriasis. The aim of this study was to evaluate the serum irisin level in psoriasis and elucidate possible associations with disease activity, inflammatory or metabolic parameters and topical treatment. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were enrolled. Blood samples were collected before and after two weeks of therapy. Serum irisin concentrations were examined by enzyme-linked immunosorbent assay (ELISA). The results were correlated with psoriasis area and severity index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and effectiveness of topical treatment. Irisin serum levels were insignificantly increased in psoriatic patients in comparison to the controls (p = 0.38). No significant correlations between investigated adipokine and several indicators of metabolic disorders, nor BMI (p = 0.37) or PASI (p = 0.5) were found. Significant positive correlations with C-reactive protein (CRP) (0.009), lipocalin-2 (p = 0.02), age (p = 0.02) and disease duration (p = 0.008) were noted. After topical treatment, serum irisin level did not significantly change (p = 0.31), despite clinical improvement. Irisin might be a marker of inflammation in psoriatic patients, but may not be a reliable indicator of metabolic conditions, severity of psoriasis nor efficacy of antipsoriatic treatment.

    Objective: To evaluate the value of combined determination of serum levels of TBA, PC-III, IV-C, HA, CG and LN in diagnosis of chronic hepatic diseases. Methods: Serum TBA levels were measured with totally automatic enzymatic method and the other five markers with RIA in 118 patients with various types of hepatic diseases as well as in 31 controls. Results: Serum levels of TBA and the other markers were significantly higher in the patients than those in the controls (p<0.01). Among the various types of diseases, values of the tested markers increased along with the increase of the severity of the disease process. Conclusion: Combined measurements of serum levels of TBA and other five markers were of important value for the diagnosis, treatment and outcome prediction of hepatic fibrosis

    Full Text Available To provide the review of the macrophage activity products as pathophysiological markers of endometriosis by literature survey (PubMed, Cochrane. Immunoreactive cells and several of their synthesis products concentrations are elevated in the serum and peritoneal fluid in patients with endometriosis. The enhanced reactive proteins contributed to local inflammation and aggregation of endometriotic lesions. Immune response and immune surveillance of tissue play an important role in pathogenesis of endometriosis. Activated macrophages in peritoneal environment secrete immunoreactive cytokines which are responsible for inflammatory cascade of reactions. The immunoreactive cytokines should be a target not only as a disease marker but also as a part of therapeutic protocol.

    Increased levels of C-reactive protein (CRP) have been considered as a marker in assessing neurogenic inflammation of migraine patients. An inverse relationship between serum bilirubin and CRP has been observed in various diseases. Therefore, we analyzed serum bilirubin levels in migraine patients, and investigated the relationship between serum bilirubin and CRP in migraineurs. A total of 86 newly diagnosed migraine patients were consecutively recruited to this study. Significantly lower median serum total bilirubin, conjugated bilirubin (CB) and unconjugated bilirubin were found in patients with migraine than healthy controls, and the levels of CRP were significantly higher in migraine patients than healthy controls. A negative correlation between CRP and CB was observed in patients with migraine (r = -0.255, P = 0.018). In a multiple linear regression model, the concentrations of CRP remained negatively correlated with CB. Our study demonstrates that serum bilirubin concentrations are decreased in migraineurs, and CB levels were found to be positively correlated with CRP in migraine patents. However, larger cross-sectional and prospective studies are needed to establish whether serum bilirubin may be a useful biomarker for assessing neurogenic inflammation in migraine patients and eventually guiding the therapy. © 2016 Wiley Periodicals, Inc.

  11. Relationship between serum levels of triglycerides and vascular inflammation, measured as COX-2, in arteries from diabetic patients: a translational study

    2013-01-01

    Background Inflammation is a common feature in the majority of cardiovascular disease, including Diabetes Mellitus (DM). Levels of pro-inflammatory markers have been found in increasing levels in serum from diabetic patients (DP). Moreover, levels of Cyclooxygenase-2 (COX-2) are increased in coronary arteries from DP. Methods Through a cross-sectional design, patients who underwent CABG were recruited. Vascular smooth muscle cells (VSMC) were cultured and COX-2 was measured by western blot. Biochemical and clinical data were collected from the medical record and by blood testing. COX-2 expression was analyzed in internal mammary artery cross-sections by confocal microscopy. Eventually, PGI2 and PGE2 were assessed from VSMC conditioned media by ELISA. Results Only a high glucose concentration, but a physiological concentration of triglycerides exposure of cultured human VSMC derived from non-diabetic patients increased COX-2 expression .Diabetic patients showed increasing serum levels of glucose, Hb1ac and triglycerides. The bivariate analysis of the variables showed that triglycerides was positively correlated with the expression of COX-2 in internal mammary arteries from patients (r2 = 0.214, P < 0.04). Conclusions We conclude that is not the glucose blood levels but the triglicerydes leves what increases the expression of COX-2 in arteries from DP. PMID:23642086

    The neuropeptide alpha-melanocyte stimulating hormone (alpha-MSH) reduces fever and acute inflammation in the skin when administered centrally. The aim of the present research was to determine whether central alpha-MSH can also reduce signs of systemic inflammation in mice with endotoxemia. Increases in serum tumor necrosis factor-alpha and nitric oxide, induced by intraperitoneal administration of endotoxin, were modulated by central injection of a small concentration of alpha-MSH. Inducible nitric oxide synthase (iNOS) activity and iNOS mRNA in lungs and liver were likewise modulated by central alpha-MSH. Lung myeloperoxidase activity, a marker of neutrophil infiltration, was increased in endotoxemic mice; the increase was significantly less in lungs of mice treated with central alpha-MSH. Intraperitoneal administration of the small dose of alpha-MSH that was effective centrally did not alter any of the markers of inflammation. In experiments using immunoneutralization of central alpha-MSH, we tested the idea that endogenous peptide induced within the brain during systemic inflammation modulates host responses to endotoxic challenge in peripheral tissues. The data showed that proinflammatory agents induced by endotoxin in the circulation, lungs, and liver were significantly greater after blockade of central alpha-MSH. The results suggest that anti-inflammatory influences of neural origin that are triggered by alpha-MSH could be used to treat systemic inflammation.

    Objective: To study the dynamic changes of serum levels of several tumor markers after implantation of 125 I seeds as treatment for breast, prostate and lung malignancies. Methods: Serum CA15-3 (in 48 cases of breast cancer), PSA (in 59 cases of prostate cancer) and CYFRA21-1 (in 59 cases of lung cancer) levels were measured with RIA both before and after implantation of 125 I seeds as treatment. Furthermore, dynamic observation on the serum markers levels was carried out every 3 months in ten patients in each category. Results: After treatment, levels of these markers dropped significantly. Dynamic observation revealed that in the 10 cases of breast cancer, the levels of CA15-3 dropped continually. However, in the 10 cases of prostatic cancer, the disease got worse and the PSA levels kept increasing. In the lung cancer group, the CYFRA21-1 levels rose markedly and all patients expired before 9 months. Conclusion: Dynamic observation on changes of serum tumor markers (CA15-3, PSA, CYFRA21-1) levels after 125 I seed implantation treatment was of definite prognostic value. (authors)

    Full Text Available Antibiotic-induced endotoxin release is associated with high mortality rate even when appropriate antibiotics are used for the treatment of severe infections in intensive care units. Since liver is involved in systemic clearance and detoxification of endotoxin hence it becomes a primary target organ for endotoxin mediated inflammation. Currently available anti-inflammatory drugs give rise to serious side effects. Hence, there is an urgent need for safe and effective anti-inflammatory therapy. It is likely that anti-inflammatory phytochemicals and neutraceutical agents may have the potential to reduce the endotoxin mediated inflammation and complications associated with endotoxin release. Keeping this in mind, the present study was planned to evaluate the hepatoprotective potential of zingerone (active compound of zingiber officinale against liver inflammation induced by antibiotic mediated endotoxemia. The selected antibiotics capable of releasing high content of endotoxin were employed for their in vivo efficacy in P.aeruginosa peritonitis model. Released endotoxin induced inflammation and zingerone as co-anti-inflammatory therapy significantly reduced inflammatory response. Improved liver histology and reduced inflammatory markers MDA, RNI, MPO, tissue damage markers (AST, ALT, ALP and inflammatory cytokines (MIP-2, IL-6 and TNF-α were indicative of therapeutic potential of zingerone. The mechanism of action of zingerone may be related to significant inhibition of the mRNA expression of inflammatory markers (TLR4, RelA, NF-kB2, TNF- α, iNOS, COX-2 indicating that zingerone interferes with cell signalling pathway and suppresses hyper expression of cell signaling molecules of inflammatory pathway. Zingerone therapy significantly protected liver from endotoxin induced inflammatory damage by down regulating biochemical as well as molecular markers of inflammation. In conclusion, this study provides evidence that zingerone is a potent anti

    Low levels of serum 25-hydroxy vitamin D (25(OH)D) are common in type 2 diabetic patients and cause several complications particularly, in postmenopausal women due to their senile and physiological conditions. This study aimed to assess the effects of vitamin D-fortified low fat yogurt on glycemic status, anthropometric indexes, inflammation, and bone turnover in diabetic postmenopausal women. In a randomized, placebo-controlled, double-blind parallel-group clinical trial, 59 postmenopausal women with type 2 diabetes received fortified yogurt (FY; 2000 IU vitamin D in 100 g/day) or plain yogurt (PY) for 12 weeks. Glycemic markers, anthropometric indexes, inflammatory, and bone turnover markers were assessed at baseline and after 12 weeks. After intervention, in FY group (vs PY group), were observed: significant increase in serum 25(OH)D and decrease of PTH (stable values in PY); significant improvement in serum fasting insulin, HOMA-IR, HOMA-B, QUICKI, and no changes in serum fasting glucose and HbA1c (significant worsening of all indexes in PY); significant improvement in WC, WHR, FM, and no change in weight and BMI (stable values in PY); significant increase of omentin (stable in PY) and decrease of sNTX (significant increase in PY). Final values of glycemic markers (except HbA1c), omentin, and bone turnover markers significantly improved in FY group compared to PY group. Regarding final values of serum 25(OH)D in FY group, subjects were classified in insufficient and sufficient categories. Glycemic status improved more significantly in the insufficient rather than sufficient category; whereas the other parameters had more amelioration in the sufficient category. Daily consumption of 2000 IU vitamin D-fortified yogurt for 12 weeks improved glycemic markers (except HbA1c), anthropometric indexes, inflammation, and bone turnover markers in postmenopausal women with type 2 diabetes. www.irct.ir (IRCT2013110515294N1).

    Reconsidering when to initiate renal replacement therapy (RRT) in patients with chronic kidney disease (CKD) has been emphasized recently. With evolving modern aged and diabetes-prone populations, conventional markers of uremia are not sufficient for determining the optimal timing for dialysis initiation. This retrospective cohort study examined the association between hyperphosphatemia and uremic patients who need RRT registration. All patients from the department of nephrology in one tertiary medical center in northern Taiwan who had advanced CKD and estimated glomerular filtration rates regression models were used to identify factors associated with hemodialysis initiation decision making. During the study period, 209 of 292 patients with advanced CKD were enrolled in hemodialysis program and 83 patients (controls) were not. Univariable analysis indicated that male sex, current smoking, diabetes mellitus, hypertension, coronary artery disease, high serum creatinine level, and high serum phosphate level were associated with initiation of hemodialysis. Multivariable analysis indicated that those with higher serum phosphate level (odds ratio [OR] = 2.4, 95% confidence interval [CI] = 1.6-3.5, p = 1.4 × 10(-5)) and being in nephrology care for <12 months (OR = 0.4, 95% CI = 0.2-0.8, p = 0.016) tended to be significant markers for hemodialysis initiation. Hyperphosphatemia, in addition to conventional laboratory markers and uremic symptoms, may be a useful marker to determine timing of hemodialysis initiation in patients with advanced CKD.

    Full Text Available Under specific conditions non-steroidal anti-inflammatory drugs (NSAIDs may be used to lower therapy-resistant proteinuria. The potentially beneficial anti-proteinuric, tubulo-protective, and anti-inflammatory effects of NSAIDs may be offset by an increased risk of (renal side effects. We investigated the effect of indomethacin on urinary markers of glomerular and tubular damage and renal inflammation. We performed a post-hoc analysis of a prospective open-label crossover study in chronic kidney disease patients (n = 12 with mild renal function impairment and stable residual proteinuria of 4.7±4.1 g/d. After a wash-out period of six wks without any RAAS blocking agents or other therapy to lower proteinuria (untreated proteinuria (UP, patients subsequently received indomethacin 75 mg BID for 4 wks (NSAID. Healthy subjects (n = 10 screened for kidney donation served as controls. Urine and plasma levels of total IgG, IgG4, KIM-1, beta-2-microglobulin, H-FABP, MCP-1 and NGAL were determined using ELISA. Following NSAID treatment, 24 h -urinary excretion of glomerular and proximal tubular damage markers was reduced in comparison with the period without anti-proteinuric treatment (total IgG: UP 131[38-513] vs NSAID 38[17-218] mg/24 h, p<0.01; IgG4: 50[16-68] vs 10[1-38] mg/24 h, p<0.001; beta-2-microglobulin: 200[55-404] vs 50[28-110] ug/24 h, p = 0.03; KIM-1: 9[5]-[14] vs 5[2]-[9] ug/24 h, p = 0.01. Fractional excretions of these damage markers were also reduced by NSAID. The distal tubular marker H-FABP showed a trend to reduction following NSAID treatment. Surprisingly, NSAID treatment did not reduce urinary excretion of the inflammation markers MCP-1 and NGAL, but did reduce plasma MCP-1 levels, resulting in an increased fractional MCP-1 excretion. In conclusion, the anti-proteinuric effect of indomethacin is associated with reduced urinary excretion of glomerular and tubular damage markers, but not with reduced excretion of renal

    Immunosenescence contribute to increase the blood-brain barrier (BBB) permeability, leading cognitive impairment and neurodegeneration. Thus, we investigated the anti-inflammatory effect of exercise and taurine supplementation on peripheral markers of BBB, inflammation, and cognition of elderly women. Forty-eight elderly women (age, 83.58 ± 6.9 years) participated in the study, and were allocated into combined exercise training (CET: n = 13), taurine supplementation (TAU: n = 12), exercise training associated with taurine (CET+TAU: n = 11), or control (CG: n = 12) groups. Exercise was applied twice a week (multi-modal exercise). Taurine ingestion was 1.5 g., once a day. Participants were evaluated before and after 14-weeks of intervention. Plasma levels of interleukin (IL)-1β, IL-1ra, IL-6, IL-10, IL-17, tumor necrosis factor alpha (TNF-α), and serum concentration of S100β and neuron specific enolase (NSE) were determined. The mini mental state examination (MMSE) was also applied. Concentrations of S100β were maintained in all intervention groups, while a subtle increase in the CG was found. NSE levels increased only in TAU group (p < 0.05). CET reduced TNF-α, IL-6, and IL-1β/IL-1ra, IL-6/IL10, and TNF-α/IL-10 ratios (p < 0.05). TAU decreased the IL-1β/IL-1ra ratio (p < 0.05). MMSE score increased only in the CET+TAU group (p < 0.05). Multiple regression analysis showed that there was a trend for changes in IL-1β and the Charlson Comorbidity Index to be independently associated with changes in S100β. Exercise and taurine decreased inflammation, and maintained the BBB integrity in elderly women. Exercise emerged as an important tool to improve brain health even when started at advanced ages.

    The significance of Helicobacter pylori (H. pylori) infection in pediatric abdominal pain remains poorly recognized. We examined associations of H. pylori infection and serum pepsinogens (PGs), as non-invasive markers of gastritis, with pediatric abdominal pain. A case-control study was conducted among 99 children aged 5-17 years admitted to one hospital for abdominal pain (cases) without an apparent organic reason. Using enzyme-linked immunosorbent assays, sera were tested and compared with 179 controls for anti-H. pylori immunoglobulin G (IgG) antibodies and PGI and PGII levels. Multivariable analysis was performed to adjust for potential confounders. H. pylori IgG sero-positivity was 34.3 and 36.3% in cases and controls, respectively, P = 0.7. H. pylori-infected children had higher median PGI and PGII levels and a lower PGI/PGII ratio than uninfected children. Cases infected with H. pylori had a higher median PGII level (P < 0.001) and lower PGI/PGII ratio (P = 0.036) than controls infected with H. pylori. The percentage of cases with PGII ≥7.5 μg/L, as indication for antral inflammation, was higher than in controls: 58.6 versus 44.7%, P = 0.027. Children with PGII levels ≥7.5 μg/L had increased risk for abdominal pain: adjusted prevalence ratio 1.73 [95% confidence intervals 1.02, 2.93], P = 0.039. Children with increased serum PGII levels, as an indication of gastritis, are more likely to have abdominal pain. Serum PGs can be a useful non-invasive marker for gastritis, in evaluating children with severe abdominal pain with no apparent organic reason. What is Known: • The significance of Helicobacter pylori infection in pediatric abdominal pain remains debated. • Serum pepsinogens (PGs), non-invasive markers of gastric inflammation, were rarely utilized in assessing the association between H. pylori in pediatric abdominal pain of unknown origin. What is New: • High serum PGII level, as an indication of gastritis, rather than H. pylori

    Cancer associated fibroblasts are activated in the tumor microenvironment and contribute to tumor progression, angiogenesis, extracellular matrix remodeling, and inflammation. To identify proteins characteristic for fibroblasts in colorectal cancer we used liquid chromatography-tandem mass spectrometry to derive protein abundance from whole-tissue homogenates of human colorectal cancer/normal mucosa pairs. Alterations of protein levels were determined by two-sided t test with greater than threefold difference and an FDR of matrix organization, TGFβ receptor signaling and angiogenesis mainly originating from the stroma. Most prominent were increased abundance of SerpinB5 in the parenchyme and latent transforming growth factor β-binding protein, thrombospondin-B2, and secreted protein acidic-and-cysteine-rich in the stroma. Extracellular matrix remodeling involved collagens type VIII, XII, XIV, and VI as well as lysyl-oxidase-2. In silico analysis of mRNA levels demonstrated altered expression in the tumor and the adjacent normal tissue as compared to mucosa of healthy individuals indicating that inflammatory activation affected the surrounding tissue. Immunohistochemistry of 26 tumor specimen confirmed upregulation of SerpinB5, thrombospondin B2 and secreted protein acidic-and-cysteine-rich. This study demonstrates the feasibility of detecting tumor- and compartment-specific protein-signatures that are functionally meaningful by proteomic profiling of whole-tissue extracts together with mining of RNA expression datasets. The results provide the basis for further exploration of inflammation-related stromal markers in larger patient cohorts and experimental models.

    To investigate relationships between secondhand smoke exposure in young children and several preclinical markers of cardiovascular risk that have been established as relevant to adult populations. There were 139 children, 2-5 years of age, enrolled in a cross-sectional study. Secondhand smoke exposure was objectively determined by hair nicotine level; a comprehensive panel of clinical markers (morning blood pressure, fasting glucose and insulin, lipid profiles, inflammation) and research markers (markers of oxidation, endothelial stress, and endothelial repair) of cardiovascular risk status were assessed. Univariate and multivariate linear regression were used to evaluate relationships between secondhand smoke exposure and cardiovascular risk markers. Hair nicotine levels were correlated directly with blood pressure and serum C-reactive protein, and inversely correlated with serum high-density lipoprotein cholesterol and endothelial cell progenitor cell prevalence. In multivariate analyses, these relationships remained when controlled for age, sex, body mass index z-score, maternal education, and method of payment. Additionally, in multivariate analyses, hair nicotine level was significantly negatively correlated with total antioxidant capacity. These results support the view that secondhand smoke exposure in the very young has a detectable relationship with several markers of cardiovascular risk, long before the emergence of clinical disease. Further studies to define mechanisms and strategies to prevent and mitigate these risks early in life are warranted. Copyright © 2017 Elsevier Inc. All rights reserved.

    Determination by a high sensitivity technique of serum C-reactive protein (CRP), a sensitive marker of inflammation in women with preeclampsia compared to normal pregnancy and investigation of the relationship between CRP and the severity of the preeclamptic syndrome. The study included 40 women with preeclampsia and 40 control subjects with normal pregnancies in the last trimester of pregnancy. The serum CRP concentration was determined using the universal high sensitivity immunoturbidimetric assay. The serum CRP concentration was significantly higher (p preclampsia (5.69 +/- 1.8 mg/L) compared to normal pregnancy (2.89 +/- 1.2 mg/L). In women with preeclampsia, CRP correlated positively and significantly with diastolic blood pressure, proteinuria and uric acid levels. Maternal CRP values also correlated negatively and significantly with fetal weight at birth. Our results demonstrate that serum CRP is increased in preeclampsia and represents a marker of the severity of the preeclamptic syndrome and of fetal weight at birth. Taking into consideration these observations and the fact that CRP testing is rapid and relatively inexpensive, we recommend the use of this acute phase reagent in clinical practice, in all women with preeclampsia in order to establish the prognosis of the disease.

    Full Text Available Iron (Fe sequestration is described in overweight and in its associated metabolic complications, i.e., metabolic syndrome (MetS and non-alcoholic liver fatty disease (NAFLD; however, the interactions between Fe, obesity and inflammation make it difficult to recognize the specific role of each of them in the risk of obesity-induced metabolic diseases. Even the usual surrogate marker of Fe stores, ferritin, is influenced by inflammation; therefore, in obese subjects inflammation parameters must be measured together with those of Fe metabolism. This cross-sectional study in obese youth (502 patients; 57% girls: 11.4 ± 3.0 years old (x ± SD; BMI z score 5.5 ± 2.3, multivariate regression analysis showed associations between Fe storage assessed by serum ferritin with risk factors for MetS and NAFLD, assessed by transaminase levels, which were independent of overweight and the acute phase protein fibrinogen. Further studies incorporating the measurement of complementary parameters of Fe metabolism could improve the comprehension of mechanisms involved.

    Objective: To investigate the liver function damage and serum hepatic fibrosis markers levels changes in patients suffering from trichloroethylene induced drugrash-like dermatitis. Methods: Serum hyaluronic acid (HA), laminin (LN), procollagen type III (PC III), type IV collagen ( IV C) levels (with RIA), mono-amine oxidase (MAO) activity (with chemo-colorimetry) and liver function tests (including ALT, AGT, total protein, albumin, total bile acid, with automated biochemical analysis system) were determined in 30 controls and 30 patients with trichloroethylene induced drugrash-like dermatitis. Results: Severe liver function damage was demonstrated in all the patients. The serum hepatic fibrosis markers levels were significantly increased (vs controls, P<0.01) and correlated well with the degree of hepatic damage. Conclusion: Liver damage occurred early in patients with trichloroethylene induced dermatitis, accompanied with laboratory evidence of hepatic fibrosis. (authors)

    Background: Oxidative stress affects women fertility and influences on the sperm quality by alterating activities of cholinesterases, a molecular marker of stress-related infertility. The aim of the present study was to investigate the role of acetyl-cholinesterase (AChE), butyrylcholinesterase (BuChE) activities and phenotypes in patients with unexplained infertility (idiopathic). It’s possible association with inflammation marker C-reactive protein (CRP) and other oxidative stress markers, i.e. before and after intra uterine insemination (IUI). Methods: In this study, blood samples of 60 patients with unexplained infertility were collected the day before and 24 hr after IUI (between 8 AM and 9 AM after the overnight fasting) and activities of BuChE, AChE, catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GpX) and serum levels of thiol proteins (TP), C-reactive protein (CRP), total antioxidant capacity (TAC) were measured. Statistical significance was assumed at poxidative stress and inflammation and reduction in fertility rates by IUI. PMID:27478769

    Anemia is a common complication among hemodialysis (HD) patients. Although intravenous iron and erythropoiesis-stimulating agents revolutionized anemia treatment, about 10% of HD patients show suboptimal response to these agents. Systemic inflammation and increased serum hepcidin level may contribute to this hyporesponsiveness. Considering the anti-inflammatory properties of omega-3 fatty acids, this study aimed to evaluate potential role of these fatty acids in improving anemia and inflammation of chronic HD patients. In this randomized, placebo-controlled trial, 54 adult patients with HD duration of at least 3 months were randomized to ingest 1800 mg of either omega-3 fatty acids or matching placebo per day for 4 months. Anemia parameters including blood hemoglobin, serum iron, transferrin saturation (TSAT), erythropoietin resistance index, and required dose of intravenous iron and erythropoietin, and serum concentrations of inflammatory/anti-inflammatory markers including interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-10, C-reactive protein (CRP), hepcidin, ferritin, intact parathyroid hormone (iPTH), and ratios of IL-10 to IL-6 and IL-10 to TNF-α were measured at baseline and after 4 months of the intervention. 45 subjects (25 in the omega-3 and 20 in the placebo group) completed the study. No significant changes were observed in blood hemoglobin, serum iron, TSAT, and required dose of intravenous iron in either within or between group comparisons. Additionally, erythropoietin resistance index as well as required dose of intravenous erythropoietin showed no significant change in the omega-3 group compared to the placebo group. Although a relative alleviation in inflammatory state appeared in the omega-3 group, the mean differences of inflammatory and anti-inflammatory markers between the two groups did not reach statistically significant level except for IL-10-to-IL-6 ratio and serum ferritin level which showed significant changes in favor of omega-3

    We have recently identified the zinc finger and SCAN domain containing 4 (Zscan4), which is transiently expressed and regulates telomere elongation and genome stability in mouse embryonic stem (ES) cells. The aim of this study was to examine the expression of ZSCAN4 in the adult pancreas and elucidate the role of ZSCAN4 in tissue inflammation and subsequent regeneration. The expression of ZSCAN4 and other progenitor or differentiated cell markers in the human pancreas was immunohistochemically examined. Pancreas sections of alcoholic or autoimmune pancreatitis patients before and under maintenance corticosteroid treatment were used in this study. In the adult human pancreas a small number of ZSCAN4-positive (ZSCAN4+) cells are present among cells located in the islets of Langerhans, acini, ducts, and oval-shaped cells. These cells not only express differentiated cell markers for each compartment of the pancreas but also express other tissue stem/progenitor cell markers. Furthermore, the number of ZSCAN4+ cells dramatically increased in patients with chronic pancreatitis, especially in the pancreatic tissues of autoimmune pancreatitis actively regenerating under corticosteroid treatment. Interestingly, a number of ZSCAN4+ cells in the pancreas of autoimmune pancreatitis returned to the basal level after 1 yr of maintenance corticosteroid treatment. In conclusion, coexpression of progenitor cell markers and differentiated cell markers with ZSCAN4 in each compartment of the pancreas may indicate the presence of facultative progenitors for both exocrine and endocrine cells in the adult pancreas.

    Senescence-accelerated mice P1 (SAMP1) is an aging model characterized by shortened lifespan and early signs of senescence. Klotho is an aging-suppressor gene. The purpose of this study is to investigate whether in vivo expression of secreted klotho ( Skl ) gene attenuates aortic valve fibrosis in SAMP1 mice. SAMP1 mice and age-matched (AKR/J) control mice were used. SAMP1 mice developed obvious fibrosis in aortic valves, namely fibrotic aortic valve disease. Serum level of Skl was decreased drastically in SAMP1 mice. Expression of MCP-1 (monocyte chemoattractant protein 1), ICAM-1 (intercellular adhesion molecule 1), F4/80, and CD68 was increased in aortic valves of SAMP1 mice, indicating inflammation. An increase in expression of α-smooth muscle actin (myofibroblast marker), transforming growth factorβ-1, and scleraxis (a transcription factor of collagen synthesis) was also found in aortic valves of SAMP1 mice, suggesting that accelerated aging is associated with myofibroblast transition and collagen gene activation. We constructed adeno-associated virus 2 carrying mouse Skl cDNA for in vivo expression of Skl. Skl gene delivery effectively increased serum Skl of SAMP1 mice to the control level. Skl gene delivery inhibited inflammation and myofibroblastic transition in aortic valves and attenuated fibrotic aortic valve disease in SAMP1 mice. It is concluded that senescence-related fibrotic aortic valve disease in SAMP1 mice is associated with a decrease in serum klotho leading to inflammation, including macrophage infiltration and transforming growth factorβ-1/scleraxis-driven myofibroblast differentiation in aortic valves. Restoration of serum Skl levels by adeno-associated virus 2 carrying mouse Skl cDNA effectively suppresses inflammation and myofibroblastic transition and attenuates aortic valve fibrosis. Skl may be a potential therapeutic target for fibrotic aortic valve disease. © 2018 American Heart Association, Inc.

    Aging is characterized by a state of chronic, low-grade inflammation that impairs vascular function. Acute inflammation causes additional decrements in vascular function, but these responses are not uniform in older compared with younger adults. We sought to determine if older adults with low levels of baseline inflammation respond to acute inflammation in a manner similar to younger adults. We hypothesized age-related differences in the vascular responses to acute inflammation, but that older adults with low baseline inflammation would respond similarly to younger adults. Inflammation was induced with an influenza vaccine in 96 participants [older = 67 total, 38 with baseline C-reactive protein (CRP) > 1.5 mg/l and 29 with CRP < 1.5 mg/l; younger = 29]; serum inflammatory markers IL-6 and CRP, blood pressure and flow-mediated dilation (FMD) were measured 24 and 48 h later. Younger adults increased IL-6 and CRP more than the collective older adult group and increased pulse pressure, whereas older adults decreased SBP and reduced pulse pressure. The entire cohort decreased FMD from 11.3 ± 0.8 to 8.3 ± 0.7 to 8.7 ± 0.7% in younger and from 5.8 ± 0.3 to 5.0 ± 0.4 to 4.7 ± 0.4% in older adults, P less than 0.05 for main effect. Older adult groups with differing baseline CRP had the same IL-6, blood pressure, and FMD response to acute inflammation, P less than 0.05 for all interactions, but the low-CRP group increased CRP at 24 and 48 h (from 0.5 ± 0.1 to 1.4 ± 0.2 to 1.7 ± 0.3 mg/l), whereas the high-CRP group did not (from 4.8 ± 0.5 to 5.4 ± 0.5 to 5.4 ± 0.6 mg/l), P less than 0.001 for interaction. Aging, not age-related chronic, low-grade inflammation, determines the vascular responses to acute inflammation.

    Objective: To investigate the diagnostic value of combined determination of serum NSE, CA242, tissue polypeptide antigen (TPA) and CEA levels in patients with primary lung cancer. Methods: Serum NSE, CA242, TPA and CEA levels were determined with ELISA in (1) 102 patients with various types of primary lung carcinoma (adenocarcinoma 38, squamous cell carcinoma 32, small cell lung carcinoma 32) (2) 33 patients with open lung T. B. and (3) 30 controls. Results: (1) In patients with lung cancer, serum levels of all the four markers were increased and significantly higher than their respective values in patients with open lung T.B. and controls. (2) Positive rate of combined any two markers were 75% for adenocarcinoma, 50% for squamous cell carcinoma and 65% for small cell lung carcinoma, while false positive rate was only 9% for T.B patients and none for the controls. (3) The most appropriate single marker for each specific type of lung cancer was: NSE for SCLC (sensitivity 72%, specificity 97%, CA242 for adenocarcinoma sensitivity 62%, specificity 90%). Conclusion: Combined determination of these tumor markers would improve the sensitivity and specificity for diagnosis of primary lung carcinoma. (authors)

    Due to its universal applicability for early detection and prediction of cancer stage and disease recurrence, widespread implementation of serum-based prostate-specific antigen (PSA) measurements has a significant influence on current treatment strategies for men with prostate cancer (PCa). However, over-detection and the resultant over-treatment of indolent cancers have been strongly implicated to occur. Using current recommended guidelines, the PSA test suffers from both limited sensitivity and specificity to enable efficacious population-based cancer detection. Therefore, novel biomarkers are much needed to complement PSA by enhancing its diagnostic and prognostic performance. The present literature on serum markers for PCa was reviewed. PSA derivatives, molecular PSA isoforms, and novel molecular targets in blood were summarized and weighted against their potential to improve decision-making of men with PCa. Current evidence suggests that no single analyte is likely to achieve the desired level of diagnostic and prognostic accuracy for PCa. However, the combination of biomarkers with clinical and demographic data, for example, using established standard nomograms, has produced progress toward the goal of both optimal screening and risk assessment. Furthermore, potential candidate molecular markers for PCa can be derived from high-throughput technologies. Current studies demonstrate that understanding dynamic PSA changes over time may offer diagnostic and prognostic information. Bridging the gap between basic science and clinical practice represents the main goal in the near future to enable physicians to tailor risk-adjusted screening and treatment strategies for current patients with PCa.

    Full Text Available Benign prostate hypertrophy (BPH is the most common benign tumor in men due to obstruction of the urethra and, finally, uremia. Malondialdehyde (MDA is a product derived from peroxidation of polyunsaturated fatty acids and related esters. Evaluation of MDA in serum represents a non-invasive biomarker of oxidative stress. Prostate-specific antigen (PSA is a sensitive marker for prostatic hypertrophy and cancer. We analyzed MDA serum levels to evaluate the oxidative stress in BPH. To this end, 22 BPH patients and 22 healthy donors were enrolled. Data show an increase of MDA level in BPH patients and a positive correlation between PSA and MDA levels. In conclusion, we describe a previously unknown relationship between PSA and MDA as an index of inflammation and oxidative stress in BPH.

    Full Text Available Background. High value of neutrophil lymphocyte ratio (NLR is a strong independent predictor and biomarker of ongoing vascular inflammation in various cardiovascular disorders. Objective. The main focus of the study is to investigate the effect of nebivolol on NLR in mild to moderate hypertensive patients in comparison with metoprolol. In addition, BMI, blood pressure, TLC count, blood sugar, and lipid profile were also assayed before and after treatment. Materials and Methods. In this 12-week prospective double-blinded randomized study, 120 patients with mild to moderate hypertension were randomly divided into two groups to prescribed daily dose of tab nebivolol 5–10 mg and metoprolol 50–100 mg, respectively, for 12 weeks. The data were analyzed using SPSS 16 software. Results. A total of 100 patients completed the study. Both drugs lowered blood pressure significantly, nebivolol 20.5/10.5 and metoprolol 22.5/11.2 (p<0.001 from baseline. Regarding inflammation, nebivolol reduced total leukocyte count (p=0.005 and neutrophil count (p=0.003 and increased lymphocyte count (p=0.004 as compared to metoprolol. Similarly, nebivolol but not metoprolol significantly reduced NLR ratio (p=0.07. Nebivolol improved lipid profile and blood sugar compared to metoprolol, but values were nonsignificant. Conclusion. Nebivolol has a strong impact on reducing NLR, a marker of subclinical inflammation in hypertensive patients. Moreover NLR can be used as a disease and drug monitoring tool in these patients.

    Serum trace elements were analyzed by particle induced X-ray emission (PIXE) method in a patient with acute aortic dissection during the supportive process by a Nutrition support team (NST). The patient was a 53-year old male who suffered from acute aortic dissection on March 1, 2007. He received emergent Bentall operation and bow pars total displacement. Since he suffered from diarrhea as a result of hypoalbuminemia and bowel dysfunction, enteral nutrition was not sufficient to maintain adequate intake. Therefore, we also used parenteral nutrition until the 97th disease day. Afterwards, the patient managed only with enteral nutrition. We measured serum trace elements during these periods. Serum trace elements such as Fe, Zn and Se were preserved within normal ranges. On the other hand, Cu gradually decreased until the 54th disease day (44 μg/l) and stayed in the lower levels around the detection limit until the 109th disease day. Thereafter, Cu slightly increased and reached 117 μg/l on the 131st disease day (reference range of serum Cu in adult males: 700-1,300 μg/l). It was suggested that the serum levels of these trace elements might reflect the nutritional stages of the patient and could be useful as clinical markers for nutritional therapies. (author)

    Objective To identify biomarkers that distinguish between active ANCA-associated vasculitis (AAV) and remission in a manner superior or complementary to established markers of systemic inflammation. Methods Markers of vascular injury and angiogenesis were measured before and after treatment in a large clinical trial in AAV. 163 subjects enrolled in the Rituximab in ANCA-Associated Vasculitis (RAVE) trial were studied. Serum levels of E-selectin, ICAM-3, MMP1, MMP3, MMP9, P-selectin, thrombomodulin, and VEGF were measured at study screening (time of active disease) and at month 6. ESR and CRP levels had been measured at the time of the clinical visit. The primary outcome was the difference in marker level between screening and month 6 among patients in remission (BVAS/WG score of 0) at month 6. Results All subjects had severe active vasculitis (mean BVAS/WG score 8.6 +/− 3.2 SD) at screening. Among the 123 subjects clinically in remission at month 6, levels of all markers except E-selectin showed significant declines. MMP3 levels were also higher among the 23 subjects with active disease at month 6 than among the 123 subjects in remission. MMP3 levels correlated weakly with ESR and CRP. Conclusion Many markers of vascular injury and angiogenesis are elevated in severe active AAV and decline with treatment, but MMP3 appears to distinguish active AAV from remission better than the other markers studied. Further study of MMP3 is warranted to determine its clinical utility in combination with conventional markers of inflammation and ANCA titers. PMID:21953143

    Pancreatitis is associated with intraductal papillary mucinous neoplasm (IPMN). This association is in part due to inflammation from pancreatic ductal obstruction. Although the correlation between pancreatitis and the malignant potential of IPMN is unclear, the 2012 International Consensus Guidelines (ICG) consider pancreatitis a "worrisome feature." We hypothesized that serum pancreatic enzymes, markers of inflammation, are a better predictor of malignancy than pancreatitis in patients with IPMN. Between 1992 and 2012, 364 patients underwent resection for IPMN at a single university hospital. In the past decade, serum amylase and lipase were collected prospectively as an inflammatory marker in 203 patients with IPMN at initial surveillance and "cyst clinic" visits. The latest serum pancreatic enzyme values within 3 months preoperatively were studied. Pancreatitis was defined according to the 2012 revision of the Atlanta Consensus. Of the 203 eligible patients, there were 76 with pancreatitis. Pancreatitis was not associated with an increased rate of malignancy (P = .51) or invasiveness (P = .08). Serum pancreatic enzymes categorically outside of normal range (high or low) were also not associated with malignancy or invasiveness. In contrast, as a continuous variable, the higher the serum pancreatic enzymes were, the greater the rate of invasive IPMN. Of the 127 remaining patients without pancreatitis, serum pancreatic enzymes outside of normal range (low and high) were each associated with a greater rate of malignancy (P enzyme levels above normal range (high) were associated with a greater rate of invasiveness (P = .02). In patients with IPMN without a history of pancreatitis, serum pancreatic enzymes outside of the normal range are associated with a greater risk of malignancy. In patients with a history of pancreatitis, there is a positive correlation between the levels of serum pancreatic enzymes and the presence of invasive IPMN. These data suggest

    Cirrhosis is the dominant cause of portal hypertension globally but may be overshadowed by hepatosplenic schistosomiasis (HSS) in the tropics. In Zambia, schistosomiasis seroprevalence can reach 88% in endemic areas. Bacterial translocation (BT) drives portal hypertension in cirrhosis contributing to mortality but remains unexplored in HSS. Rifaximin, a non-absorbable antibiotic may reduce BT. We aimed to explore the influence of rifaximin on BT, inflammation, and fibrosis in HSS. In this phase II open-label trial (ISRCTN67590499), 186 patients with HSS in Zambia were evaluated and 85 were randomized to standard care with or without rifaximin for 42 days. Changes in markers of inflammation, BT, and fibrosis were the primary outcomes. BT was measured using plasma 16S rRNA, lipopolysaccharide-binding protein, and lipopolysaccharide, whereas hyaluronan was used to measure fibrosis. Tumor necrosis factor receptor 1 (TNFR1) and soluble cluster of differentiation 14 (sCD14) assessed inflammation. 16S rRNA reduced from baseline (median 146 copies/µL, interquartile range [IQR] 9, 537) to day 42 in the rifaximin group (median 63 copies/µL, IQR 12, 196), P < 0.01. The rise in sCD14 was lower ( P < 0.01) in the rifaximin group (median rise 122 ng/mL, IQR-184, 783) than in the non-rifaximin group (median rise 832 ng/mL, IQR 530, 967). TNFR1 decreased ( P < 0.01) in the rifaximin group (median -39 ng/mL IQR-306, 563) but increased in the non-rifaximin group (median 166 ng/mL, IQR 3, 337). Other markers remained unaffected. Rifaximin led to a reduction of inflammatory markers and bacterial 16S rRNA which may implicate BT in the inflammation in HSS.

    Serum amyloid A (SAA) is an acute phase protein that is elevated in blood during inflammation. The role of this protein in allergic diseases of airways remains unclear. The objective of this study was to evaluate the SAA in blood, lung and bronchial cells in a murine model of bronchial hypersensitivity to Aspergillus fumigatus. To achieve this purpose, different groups of 5-month-old mice were housed in cages containing hay bedding that was contaminated with A. fumigatus and were kept in an isolation room for 16 days to allow for the induction of allergic airway inflammation. Subsequently, the mice were then exposed once again to Aspergillus spores at 0, 2, 8, 24 and 72 h, and they were bled to acquire serum and sacrificed to obtain bronchoalveolar lavage fluid (BALF) or lung tissues for analysis. SAA levels were measured in lung, serum and BALF by dot blot assay and RT-PCR (reverse transcription polymerase chain reaction). The results indicated that SAA protein levels increased in both serum and lung within 2-24h after mice were exposed to Aspergillus spores. Moreover, the SAA mRNA expression levels in the lungs and BALF cells demonstrated the same trend that was observed for the protein levels through the dot blot assay; in particular, SAA mRNA levels increased within the first hour after mice were exposed to A. fumigatus. In this allergic airway model, we conclude that A. fumigatus can induce an acute inflammatory response in the airways through the stimulation of the SAA protein, increasing its levels in serum, lung tissue and BALF samples during the early hours of exposure of mice that have been sensitised for this fungus.

    Strokes are caused by disruption of the blood supply to the brain. This may result from either blockage or rupture of a blood vessel. Yearly 15 million people worldwide suffer a stroke. India ranks second worldwide in terms of deaths from stroke. The incidence of stroke increases with age affecting the economically productive middle aged population. Hypertension and male sex are other risk factors for stroke. C-Reactive Protein (CRP) is an acute phase protein whose concentration rises in blood following inflammation. Formerly, assays for CRP detected its rise only after significant inflammation. However, recently developed high sensitivity assays (hsCRP) enable the measurement of CRP in individuals who are apparently healthy. Several studies indicate that hsCRP is elevated in individuals who are at risk of developing Coronary Artery Disease or Cerebrovascular events, the elevation may be found years before the first detection of vascular problems. In the absence of other biochemical markers, the present study aimed to evaluate the predictive and diagnostic role of hsCRP in stroke. The study consisted of 50 patients of acute stroke admitted in Gauhati Medical College and Hospital. The control population consisted of two groups - 50 age and sex matched controls with hypertension (Hypertensive control group) and 50 age and sex matched controls with no obvious disease constituted the Normal control group. hsCRP levels were measured in all the groups and compared statistically. hsCRP is an acute phase reactant whose concentration rises in stroke as well as in those at risk. The rise may be identified even before the appearance of risk factors. Hence, hsCRP may be useful as a predictive and diagnostic marker in stroke.

    Full Text Available As there is effective intervention for delaying or preventing metabolic diseases, which are often present for years before becoming clinically apparent, novel biomarkers that would mark metabolic complications before the onset of metabolic disease should be identified. We investigated the role of fasting serum amino acids and their associations with inflammatory markers, adipokines, and metabolic syndrome (MetS components in subjects prior to the onset of insulin resistance (IR. Anthropometric measurements, food records, adipokines, biochemical markers, and serum levels of amino acids were determined in 96 asymptomatic subjects aged 25–49 years divided into three groups according to the number of MetS components present. Cysteine and tyrosine were significantly higher already in group with one component of MetS present compared to subjects without MetS components. Serum amino acid levels correlated with markers of inflammation and adipokines. Alanine and glycine explained 10% of insulin resistance variability. The role of tyrosine and cysteine, that were higher already with 1 component of MetS present, should be further investigated as they might point to future insulin disturbances.

    Full Text Available The utility of measuring carcinoembryonic antigen(CEA and cancer antigen 15-3 (CA15-3 levels in patients with breast cancer remains controversial. The present study aims to investigate the prognostic value of preoperative serum CEA and CA15-3 levels in breast cancer patients.Serum preoperative CEA and CA 15-3 concentration levels were measured in a total of 432 breast cancer patients. The association of tumor markers levels with clinicopathological parameters and outcomes were analyzed.Elevated serum levels of CEA and CA15-3 were identified in 47 (10.9% and 60(13.9% patients, respectively. Larger tumor size, advanced axillary lymph nodal and TNM stage exhibited higher proportion of elevated CEA and CA15-3 levels. The elevation of CEA levels was significantly greater in patients with HER2 positive tumors, and the elevation of CA15-3 levels was significantly greater in ER negative breast patients. Univariate and multivariate Cox's regression analysis revealed that elevated preoperative CEA and CA 15-3 levels were independent prognostic factors for DFS and OS. When considering the combination of both markers levels, patients with both elevated markers presented the worst survival. Independent prognostic significance of elevated preoperative serum CEA and CA15-3 levels were reconfirmed in Luminal B breast cancer.Preoperative serum levels of CEA and CA15-3 are independent prognostic parameters for breast cancer.

    The aim of this work was to investigate inflammatory, oxidative, and thrombotic parameters as biomarkers in farmers exposed to pesticides. Fifty farmers using chemical pesticides and 60 unexposed control men participated in this study. The Mediterranean diet compliance, the duration of pesticide use, and personal protection for pesticides handling were recorded using self-administered questionnaires. Serum biochemical parameters, oxidant/antioxidant, inflammatory, and thrombosis markers were determined. Our findings showed oxidative stress reflected by an increase in malondialdehyde, carbonyl proteins and superoxide anion levels and a decrease in vitamins C and E, glutathione, catalase, and superoxide dismutase activities in farmers. Serum C-reactive protein, prothrombin, and fibrinogen levels were enhanced in these farmers. In conclusion, inflammation, oxidative stress, and metabolic perturbations reflected the possibility of the effects of pesticides to farmers.

    Full Text Available Objective: To assess the diagnostic value of the protein markers in both cirrhotic patients on top of hepatitis C virus (HCV and in hepatocellular carcinoma (HCC patients on top of HCV in comparison to normal controls. Methods: A total number of 100 subjects including HCC, cirrhotic patients on top of HCV and normal controls were subjected to serum protein markers analysis for alpha-fetoprotein, apolipoprotein A1, apolipoprotein A2, insulin like growth factor 1 and insulin like growth factor 1 receptor by western blotting technique. Results: It was found that alpha-fetoprotein alone could not be used as a screening test while apolipoprotein A2 as a serum marker could be used as a non invasive screening test to differentiate a case of HCC from cirrhotic HCV patient. The all four markers were able to discriminate normal persons from HCC and cirrhotic HCV patients effectively. Conclusions: We concluded that proteomics analysis being non invasive, rapid and sensitive is a novel gate that can serve in early diagnosis and screening of HCC and cirrhotic HCV patients

    The health impact of dust events from China has become a concern within China and in its neighboring countries. Previous epidemiological studies have demonstrated an association between particulate matter exposure and cardiopulmonary mortality. Here, we use pulmonary hypertensive rat models to examine inflammation markers in the lung and in peripheral blood after exposure to Asian dust storm particles. Using a nose-only inhalation system, eight pulmonary hypertensive rats were exposed to concentrated ambient particles (CAPs) from an actual Asian dust storm that took place between March 18 and 19, 2002; four control rats were also exposed to room air. Four rats exposed to CAPs of 315.6 μg/m 3 for 6 h were classified as the low-exposure group, and another four rats exposed to CAPs of 684.5 μg/m 3 for 4.5 h were classified as the high-exposure group. The animals were sacrificed 36 h after exposure. Inflammation markers in the peripheral blood and in the bronchoalveolar lavage (BAL) were analyzed, and IL-6 in BAL was also determined using ELISA. White blood cell counts in peripheral blood increased with increased CAP exposure levels (P<0.001, test for trend). In BAL analysis, total cell numbers and the proportion of neutrophil also increased with increased CAP levels (P<0.001, test for trend for both markers). Positive dose-response relationships between CAP exposure and total protein (P<0.05) and between CAPs and LDH activity (P<0.05) were also observed. Moreover, IL-6 protein in BAL increasing with CAP levels (P<0.05, test for trend) was demonstrated. Our results revealed that exposure to particulate matters during an Asian dust storm could increase lung inflammation and injury in pulmonary hypertensive rats. Further studies are needed to determine the components of dust storm particles that may contribute to the particle toxicity

    Full Text Available Background: Women with polycystic ovary syndrome (PCOS have an increased prevalence of insulin resistance (IR and related disorders. Elevated serum levels of high sensitivity CRP (hs-CRP, interleukin-6 (IL-6 and tumor necrosis factor α (TNF-α reflect low-grade chronic inflammation and have been associated with several insulin-resistant states; they are useful cardiovascular risk markers. The objective of this study was to investigate whether soluble inflammatory markers are altered in PCOS focusing on its relationship with obesity and indexes of insulin resistance.

    Full Text Available Neuroinflammation is a constant event in Alzheimer’s disease (AD, but the current knowledge is insufficient to state whether inflammation is a cause, a promoter, or simply a secondary phenomenon in this inexorably progressive ailment. In the current paper, we review research data showing that inflammation is not a prerequisite for onset of dementia, and, although it may worsen the course of the disease, recent evidence shows that chronic inhibition of inflammatory pathways is not necessarily beneficial for patients. Prospective clinical trials with anti-inflammatory drugs failed to stop disease progression, measurements of inflammatory markers in serum and cerebrospinal fluid of patients yielded contradictory results, and recent bench research proved undoubtedly that neuroinflammation has a protective side as well. Knockout animal models for TNFRs or ILRs do not seem to prevent the pathology or the cognitive decline, but quite the contrary. In AD, the therapeutic intervention on inflammatory pathways still has a research future, but its targets probably need reevaluation.

    Identification of biomarkers assists in the diagnosis of disease and the assessment of health risks from environmental exposures. We hypothesized that rats exposed to Libby amphibole (LA) would present with a unique serum proteomic profile which could help elucidate epidemiologically-relevant biomarkers. In four experiments spanning varied protocols and temporality, healthy (Wistar Kyoto, WKY; and F344) and cardiovascular compromised (CVD) rat models (spontaneously hypertensive, SH; and SH heart failure, SHHF) were intratracheally instilled with saline (control) or LA. Serum biomarkers of cancer, inflammation, metabolic syndrome (MetS), and the acute phase response (APR) were analyzed. All rat strains exhibited acute increases in α-2-macroglobulin, and α1-acid glycoprotein. Among markers of inflammation, lipocalin-2 was induced in WKY, SH and SHHF and osteopontin only in WKY after LA exposure. While rat strain- and age-related changes were apparent in MetS biomarkers, no LA effects were evident. The cancer marker mesothelin was increased only slightly at 1 month in WKY in one of the studies. Quantitative Intact Proteomic profiling of WKY serum at 1 day or 4 weeks after 4 weekly LA instillations indicated no oxidative protein modifications, however APR proteins were significantly increased. Those included serine protease inhibitor, apolipoprotein E, α-2-HS-glycoprotein, t-kininogen 1 and 2, ceruloplasmin, vitamin D binding protein, serum amyloid P, and more 1 day after last LA exposure. All changes were reversible after a short recovery regardless of the acute or long-term exposures. Thus, LA exposure induces an APR and systemic inflammatory biomarkers that could have implications in systemic and pulmonary disease in individuals exposed to LA. -- Highlights: ► Biomarkers of asbestos exposure are required for disease diagnosis. ► Libby amphibole exposure is associated with increased human mortality. ► Libby amphibole increases circulating proteins involved

    The survival benefit of neoadjuvant therapy for patients with borderline resectable pancreatic carcinoma has been reported recently. However, prognostic factors for this strategy have not been clearly elucidated. The aim of this study was to clarify prognostic factors for patients with borderline resectable pancreatic carcinoma who received neoadjuvant chemotherapy. Medical records of 66 patients with pancreatic carcinoma with arterial contact who intended to undergo tumor resection following neoadjuvant chemotherapy were analyzed retrospectively. Prognostic factors were investigated by analyzing the clinicopathological factors with univariate and multivariate survival analyses. Gemcitabine plus S-1 was generally used as neoadjuvant chemotherapy. The objective response rate was 24%, and normalization of serum tumor markers following neoadjuvant chemotherapy was achieved in 29 patients (44%). Of the 66 patients, 60 patients underwent tumor resection and the remaining six patients did not due to distant metastases following neoadjuvant chemotherapy. For all 66 patients, overall 1-, 2-, and 5-year survival rates were 87.8, 54.5, and 20.5%, respectively (median survival time, 27.1 months) and multivariate analysis revealed that normalization of serum tumor markers was found to be an independent prognostic factor of better overall survival (P = 0.023). Moreover, for 60 patients who undergo tumor resection, normalization of serum tumor markers (P = 0.005) was independently associated with better overall survival by multivariate analysis. Patients with pancreatic carcinoma with arterial contact who undergo neoadjuvant chemotherapy and experience normalization of serum tumor markers thereafter may be good candidates for tumor resection.

    The aim of the present study was to assess the effects of subclinical inflammation on specific humoral immunity in dogs vaccinated with Nobivac® DHP based on serum levels of CRP and Hp. Dogs from the group I were administered Nobivac® DHP, the vaccine against distemper, infectious hepatitis and parvovirus whereas group II animals received subcutaneous turpentine oil to induce subclinical inflammation, followed by Nobivac® DHP after 24 h. Animals in group III received only turpentine oil in the way and amount identical to that as in group II. Nobivac DHP relatively poorly induced the immune inflammatory response showing good immunogenic properties, which was evidenced by only a double increase in mean CRP and Hp levels associated with antigenic stimulation in group I. In group II, serum neutralization (SN) and haemagglutination inhibition (HI) results were quite closely correlated with serum levels of CPR and Hp. Our findings suggest that the efficacy of vaccinations in dogs can be significantly affected by subclinical inflammations, which is indicated by a correlation between serum CRP and Hp levels versus antibody titres for canine distemper and parvovirus in both experimental groups of dogs (group I and II). The correlation of mean CRP and Hp values in dogs with subclinical inflammation and after vaccination with the kinetics of increasing antibody titres against distemper and parvovirus in group II dogs reflects the severity of inflammatory response and the extent of specific humoral immunity. Routine determinations of serum CRP and Hp levels as the indices of inflammation severity can be the essential biochemical markers for assessment of dogs' health in the period preceding specific immunoprophylaxis and efficacy of the vaccine.

    To investigate whether serum neurofilament light (NfL) concentration is increased in familial Alzheimer disease (FAD), both pre and post symptom onset, and whether it is associated with markers of disease stage and severity. We recruited 48 individuals from families with PSEN1 or APP mutations to a cross-sectional study: 18 had symptomatic Alzheimer disease (AD) and 30 were asymptomatic but at 50% risk of carrying a mutation. Serum NfL was measured using an ultrasensitive immunoassay on the single molecule array (Simoa) platform. Cognitive testing and MRI were performed; 33 participants had serial MRI, allowing calculation of atrophy rates. Genetic testing established mutation status. A generalized least squares regression model was used to compare serum NfL among symptomatic mutation carriers, presymptomatic carriers, and noncarriers, adjusting for age and sex. Spearman coefficients assessed associations between serum NfL and (1) estimated years to/from symptom onset (EYO), (2) cognitive measures, and (3) MRI measures of atrophy. Nineteen of the asymptomatic participants were mutation carriers (mean EYO -9.6); 11 were noncarriers. Compared with noncarriers, serum NfL concentration was higher in both symptomatic ( p < 0.0001) and presymptomatic mutation carriers ( p = 0.007). Across all mutation carriers, serum NfL correlated with EYO (ρ = 0.81, p < 0.0001) and multiple cognitive and imaging measures, including Mini-Mental State Examination (ρ = -0.62, p = 0.0001), Clinical Dementia Rating Scale sum of boxes (ρ = 0.79, p < 0.0001), baseline brain volume (ρ = -0.62, p = 0.0002), and whole-brain atrophy rate (ρ = 0.53, p = 0.01). Serum NfL concentration is increased in FAD prior to symptom onset and correlates with measures of disease stage and severity. Serum NfL may thus be a feasible biomarker of early AD-related neurodegeneration. Copyright © 2017 The Author(s).

    To further our understanding of the pathogenesis of chondromalacia of the patella (CM), we have studied the release into knee joint fluid and serum, obtained from patients with CM, of molecules associated with the metabolism of joint cartilage matrix and synovium. Interleukin-1 alpha (IL-1 alpha), interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), stromelysin-1 (MMP-3), interstitial collagenase (MMP-1), tissue inhibitor for metalloproteinases-1 (TIMP-1), phospholipase activity A2 (PLA2), hyaluronan (HA), aggrecan fragments (AGN) and antigenic keratan sulfate (KS) were quantified in knee joint lavage fluid from 96 patients with CM; KS and HA also was measured in serum. Chondromalacia was graded on a scale of I to IV according to Outerbridge (1961). The histopathology of the synovial membrane close to the patellofemoral joint was evaluated. Control samples were obtained from nine patients with knee pain presenting with arthroscopically normal knee joints. The concentrations of MMP-3, MMP-1 and TIMP-1 proteins in joint lavage fluid were increased in advanced (grade IV) CM, compared with controls. Levels of MMP-1 in lavage fluid correlated with the severity of CM (r = 0.38, P < 0.01) and MMP-1 and MMP-3 concentrations correlated with each other (r = 0.45, P < 0.001). TIMP-1 was elevated in grade IV CM compared with grades II and III CM (P < 0.02, P < 0.01). Interleukins (IL-1 alpha, IL-1 beta and IL-6) showed no significant change in CM. The lavage fluid level of PLA2 increased with the severity of CM (r = 0.40, P < 0.001). Serum KS was higher in CM IV than in controls (P = 0.05), while lavage fluid KS concentration was elevated in CM I (P = 0.04). There were no differences in the lavage fluid levels of AGN and HA between the different study groups. Synovium showed slight or moderate histological signs of inflammation in 9% of CM patients. The changes in the release and activity of these marker molecules from serum and synovial fluid may reflect changes in the

One way analyses of variance wereused to test the difference between groups. To determine which of the two groups’ meanswere significantly different, the post-hoc test of Bonferroni was used. The results wereaveraged as mean ± standard deviation. In the above test, P values less than 0.05 weretaken to be statistically significant. The normality of data was checked before thestatistical analysis was performed.Results: The study revealed statistically significant variations in serum levels ofadvanced oxidation protein products (P<0.001. Serum levels of total protein showedextensive variations; therefore the results were largely inconclusive and statisticallyinsignificant.Conclusion: The results emphasize the need for more studies with larger samplesizes to be conducted before a conclusive role can be determined for sera levels of totalprotein and advanced oxidation protein products as markers both for diagnosticsignificance and the transition from the various oral pre-cancerous lesions and conditionsinto frank oral cancers.

    Despite treatment of patients with metastatic colorectal cancer (mCRC) with bevacizumab plus chemotherapy, response rates are modest and there are no biomarkers available that will predict response. The aim of this study was to assess if markers associated with three interconnected cancer-associated biological processes, specifically angiogenesis, inflammation and oxidative damage, could stratify the survival outcome of this cohort. Levels of angiogenesis, inflammation and oxidative damage markers were assessed in pre-bevacizumab resected tumour and serum samples of mCRC patients by dual immunofluorescence, immunohistochemistry and ELISA. This study identified that specific markers of angiogenesis, inflammation and oxidative damage stratify survival of patients on this anti-angiogenic treatment. Biomarkers of immature tumour vasculature (% IMM, p=0.026, n=80), high levels of oxidative damage in the tumour epithelium (intensity of 8-oxo-dG in nuclear and cytoplasmic compartments, p=0.042 and 0.038 respectively, n=75) and lower systemic pro-inflammatory cytokines (IL6 and IL8, p=0.053 and 0.049 respectively, n=61) significantly stratify with median overall survival (OS). In summary, screening for a panel of biomarkers for high levels of immature tumour vasculature, high levels of oxidative DNA damage and low levels of systemic pro-inflammatory cytokines may be beneficial in predicting enhanced survival outcome following bevacizumab treatment for mCRC.

  5. Magnesium deficiency and increased inflammation: current perspectives

    Full Text Available Forrest H Nielsen Research Nutritionist Consultant, Grand Forks, ND, USA Abstract: Animal studies have shown that magnesium deficiency induces an inflammatory response that results in leukocyte and macrophage activation, release of inflammatory cytokines and acute-phase proteins, and excessive production of free radicals. Animal and in vitro studies indicate that the primary mechanism through which magnesium deficiency has this effect is through increasing cellular Ca2+, which is the signal that results in the priming of cells to give the inflammatory response. Primary pro-inflammatory cytokines such as tumor necrosis factor-α and interleukin (IL-1; the messenger cytokine IL-6; cytokine responders E-selectin, intracellular adhesion molecule-1 and vascular cell adhesion molecule-1; and acute-phase reactants C-reactive protein and fibrinogen have been determined to associate magnesium deficiency with chronic low-grade inflammation (inflammatory stress. When magnesium dietary intake, supplementation, and/or serum concentration suggest/s the presence of magnesium deficiency, it often is associated with low-grade inflammation and/or with pathological conditions for which inflammatory stress is considered a risk factor. When magnesium intake, supplementation, and/or serum concentration suggest/s an adequate status, magnesium generally has not been found to significantly affect markers of chronic low-grade inflammation or chronic disease. The consistency of these findings can be modified by other nutritional and metabolic factors that affect inflammatory and oxidative stress. In spite of this, findings to date provide convincing evidence that magnesium deficiency is a significant contributor to chronic low-grade inflammation that is a risk factor for a variety of pathological conditions such as cardiovascular disease, hypertension, and diabetes. Because magnesium deficiency commonly occurs in countries where foods rich in magnesium are not consumed in

    This study aimed to compare concentrations of serum 25-hydroxy vitamin D and inflammatory markers in metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO), and to determine whether the relationship between vitamin D levels and both cardiometabolic and inflammatory markers differs between MHO and MUO. This cross-sectional study comprised 4391 obese subjects aged>18 years. A panel of cardiometabolic and inflammatory markers, including anthropometric variables, glycaemic indices, lipid profiles, liver enzymes, homocysteine, C-reactive protein (CRP), fibrinogen and serum 25-hydroxy vitamin D levels, was investigated. All cardiometabolic and inflammatory markers in MHO and MUO as well as in vitamin D deficiency were compared. Prevalence of MHO was 41.9% in our obese subjects using International Diabetes Federation criteria. Considering insulin resistance and inflammation, the prevalence of MHO was 38.4%. Individuals with MHO had significantly higher vitamin D concentrations compared with MUO, and this difference in vitamin D status persisted after accounting for BMI and waist circumference. Subjects with MHO had significantly better metabolic status, lower liver enzymes, lower inflammatory markers and higher serum 25-hydroxy vitamin D than those with MUO. Associations between vitamin D levels and inflammatory and cardiometabolic markers differed according to MHO/MUO status. Among MUO subjects, vitamin D deficiency was associated with higher liver marker and homocysteine levels. Serum vitamin D was negatively associated with fasting plasma glucose and HbA1c in MHO only. Serum 25-hydroxy vitamin D levels were lower in MUO vs MHO, and reduced vitamin D concentrations were more strongly associated with cardiometabolic and inflammatory markers in MUO than in MHO subjects. These findings suggest that a deficiency in vitamin D could be a key component of MUO. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    The aim of the present study was to evaluate the levels and correlation of human S100A12 and high-sensitivity C-reactive protein (hs-CRP) in gingival crevicular fluid (GCF) and serum in chronic periodontitis (CP) subjects with and without type 2 diabetes mellitus (DM). A total of 44 subjects were divided into three groups: group 1 had 10 periodontally healthy subjects, group 2 consisted of 17 CP subjects and group 3 had 17 type 2 DM subjects with CP. GCF and serum levels of human S100A12 and hs-CRP were quantified using enzyme-linked immunosorbent assay and immunoturbidimetric analysis, respectively. The clinical outcomes evaluated were gingival index, probing depth and clinical attachment level and the correlations of the two inflammatory mediators with clinical parameters were evaluated. Both human S100A12 and hs-CRP levels increased from group 1 to group 2 to group 3. The GCF and serum values of both these inflammatory mediators correlated positively with each other and with the periodontal parameters evaluated (p < 0.05). Human S100A12 and hs-CRP can be considered as possible GCF and serum markers of inflammatory activity in CP and DM.

    Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term poor airflow. Tobacco smoking is the most common cause of COPD. In this study, we aimed to assess the vascular endothelial growth factor (VEGF) and inflammation markers on smokers and non-smoking individuals. Our study was a case-control study and 175 individuals who want to give up smoking constituted the case group. As a control group, 175 individuals who never smoked. The mean age of 350 participants was 35.83 ± 13.11 years. Educational status of the non-smokers was significantly higher than that of the smoking group (P study, IL-6 inflammatory marker and VEGF levels were found to be high and IL-10 anti-inflammatory marker was discovered to be low in smokers. For this reason, raising awareness in the society about the harms of smoking and encouraging people to give it up have become more challenging to counteract the inflammatory effects of smoking in human body and to prevent many smoking-related diseases. © 2017 John Wiley & Sons Ltd.

    The aim of this review was to evaluate the clinical significance of serum tumor markers, particularly CEA, CA19-9, and CA72-4, in patients with gastric cancer. A systematic literature search was performed using PubMed/MEDLINE with the keywords "gastric cancer" and "tumor marker," to select 4,925 relevant reports published before the end of November 2012. A total of 187 publications contained data for CEA and CA19-9, and 19 publications contained data related to all three tumor markers. The positive rates were 21.1 % for CEA, 27.8 % for CA19-9, and 30.0 % for CA72-4. These three markers were significantly associated with tumor stage and patient survival. Serum markers are not useful for early cancer, but they are useful for detecting recurrence and distant metastasis, predicting patient survival, and monitoring after surgery. Tumor marker monitoring may be useful for patients after surgery because the positive conversion of tumor markers usually occurs 2-3 months before imaging abnormalities. Among other tumor markers, alpha-fetoprotein (AFP) is useful for detecting and predicting liver metastases. Moreover, CA125 and sialyl Tn antigens (STN) are useful for detecting peritoneal metastases. Although no prospective trial has yet been completed to evaluate the clinical significance of these serum markers, this literature survey suggests that combinations of CEA, CA19-9, and CA72-4 are the most effective ways for staging before surgery or chemotherapy. In particular, monitoring tumor markers that were elevated before surgery or chemotherapy could be useful for detection of recurrence or evaluation of the response.

    The presence of serum tumor markers, carbohydrate antigen 242 (CA242), carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA), tumor-supplied group of factors (TSGF) and tumor necrosis factor-α (TNF-α), is closely associated with invasion and metastasis of many malignancies. The expression of these markers were measured in serum taken from 37 pancreatic cancer patients prior to treatment. Levels of CA242, CA199, CA125, CEA and TNF-α expression correlated with tumor size, clinical stage, tumor differentiation, lymph node and liver metastasis (P markers were significantly reduced compared with levels prior to cryosurgery (P 0.05). Thus, cryosurgery is more effective than chemotherapy for decreasing CA242, CA199, CA125, CEA, TSGF and TNF-α serum levels in these patients.

    Exposure to disinfectants and disinfection byproducts (DBPs) due to swimming in chlorinated water has been associated with allergic and respiratory health effects, including asthma. Biological mechanisms contributing to these associations are largely unknown. We hypothesized a potential pathway involving modulation of the immune system. We assessed levels of immune markers (CCL11, CCL22, CXCL10, CRP, EGF, GCSF, IL-8, IL-17, IL-1RA, MPO, VEGF, Periostin) in serum collected from 30 women and 29 men before and after 40min of swimming in a chlorinated pool. Exposure to DBPs was assessed by measuring bromodichloromethane, bromoform, chloroform, and dibromochloromethane in exhaled breath before and after swimming. Covariate data including information on physical activity was available through questionnaires and measurements. We assessed the association between indicators of swimming in a chlorinated pool and changes in serum immune marker concentrations using linear regression with bivariate normal distributions and adjusted for multiple comparisons by applying the Benjamini-Hochberg procedure. We observed a significant decrease in serum concentrations of IL-8 (-12.53%; q=2.00e-03), CCL22 (-7.28%; q=4.00e-04), CCL11 (-7.15%; q=9.48e-02), CRP (-7.06%; q=4.68e-05), and CXCL10 (-13.03%; q=6.34e-14) and a significant increase in IL-1RA (20.16%; q=4.18e-06) from before to after swimming. Associations with quantitative measurements of DBPs or physical activity were similar in direction and strength. Most of the observed associations became non-significant when we adjusted the effects of exposure to DBPs for physical activity or vice-versa. Our study indicates that swimming in a chlorinated pool induces perturbations of the immune response through acute alterations of patterns of cytokine and chemokine secretion. The observed effects could not be uniquely attributed to either exposure to DBPs or physical activity. Evidence in the literature suggests that observed decreases in

    The change and the prognostic value of serum hepatocyte growth factor and AFP level in patients with cirrhosis and/or primary liver cancer (HCC) were investigated. The level of serum hepatocyte growth factor was determined by using enzyme-linked immunosorbent assay, and AFP was determined by using radioimmunoassay in 29 patients with cirrhosis. Twenty five patients with primary liver cancer (13 patients without nodular cirrhosis and 12 patients with nodular cirrhosis) were categorized according to tumour size (≤ or >5 cm) and the level of AFP (≤ or > 200 ng/dl). The correlation between serum AFP and hepatocyte growth factor were significantly increased (P 0.05). Serum AFP can significantly discriminate between all studied groups (P 0.001) except for the comparison between control and cirrhosis (P>0.05), and also between HCC and HCC without nodular cirrhosis and HCC with cirrhosis (P>0.05). Serum HGF and AFP levels were positively affected by tumour size and nodular cirrhosis (P<0.001). Also, serum HGF level was highly affected by the levels of serum AFP in HCC patients. Non-significant correlation was observed between serum hepatocyte growth factor and AFP in control, cirrhosis, cirrhosis and HCC patients with AFP ? 200 ng/dl. It could be concluded that the over expressions of the hepatocyte growth factor and AFP may indicate an adverse prognosis for patients with cirrhosis and/or liver cancer. The sustained high level of serum hepatocyte growth factor in cirrhosis and/or HCC could be considered a factor related to early tumour diagnosis, so, serum HGF level may be used as a non-invasive marker in diagnosis and prognosis of liver malignancy. However, further studies are highly recommended to evaluate the role of HGF or its constituents in diagnosis and/or therapy in the future in a larger cohort of patients with different stages of liver malignancy

    Objective: To explore the desirability of setting a routine of test for detection of the serum markers of several viral infections hospitalized patients before anticipated blood exposure. Methods: Serum levels of five HBV markers, anti-HCV, anti-HIV (with ELISA) and ALT were determined in 214 hospitalized patients before forthcoming blood exposure as well as in 2468 controls. Results: The positive rate of each of the above-mentioned markers in the patients was: HBsAg 15.2% (397/2614), HBcAb- IgG 72.5% (1895/2614), anti-HCV 3.91% (102/2614), anti- HIV 0.08% (2/2614) and ALT level was above 40 u in 8.7% of the patients (227/2614). Each of the positive rate was significantly higher than that in the controls. Conclusion: There is a substantial portion of subjects harboring viral infections in the hospitalized patients. It is imperative to have these patients identified before blood exposure so that proper cautions can be taken and preventive measures implemented to minimize possible nosocomial as well as patients-to-staff infections. Moreover, any potential legal problems can also be appropriately dealt with. (authors)

Thus, the purpose of this study was to investigate the relationship between vitamin D status and pro- and anti-inflammatory cytokines (as markers of inflammation and immune system function in endurance athletes.Patients and methods: We analyzed fasting blood samples from 19 healthy, endurance-trained male and female runners (following a standardized diet and exercise regimen for vitamin D status (serum 25-hydroxyvitamin D [25(OHD] and specific plasma cytokine concentrations (tumor necrosis factor alpha [TNF-α], interferon-gamma [IFN-γ], interleukin [IL]-4, and IL-10. Serum/plasma concentrations were log-transformed and simple regression analysis was used to determine significant associations between 25(OHD and cytokine concentrations.Results: Forty-two percent of participants had insufficient vitamin D status [25(OHD < 32 ng/mL], whereas 11% were deficient [25(OHD , 20 ng/mL]. TNF-α and IL-4 were variable, ranging from 2.9 to 36.4 pg/mL and 0 to 252.1 pg/mL, respectively. Concentrations of IFN-γ and IL-10 were minimal, with means of 6.7 ± 7.0 pg/mL and 4.8 ± 5.1 pg/mL, respectively. Regression analysis revealed a significant inverse association between 25(OHD and TNF-α concentrations (R2 = 56.5, P < 0.001 but not between 25(OHD and the remaining cytokines, IFN-γ, IL-4, and IL-10 (P = 0.477, 0.694, and 0.673, respectively.Conclusion: These results call further attention to the epidemic of vitamin D insufficiency, even in outdoor athletes, and support a possible link between decreased vitamin D status and one

    Full Text Available Atherosclerosis plays a key role in the development of cardiovascular diseases, and is often associated with oxidative stress and local inflammation. Thymol, a major polyphenolic compound in thyme, exhibits antioxidant and anti-inflammatory properties. In this study, we measured the in vitro antioxidant activity of thymol, and investigated the effect of thymol on high-fat-diet-induced hyperlipidemia and atherosclerosis. New Zealand white rabbits were fed with regular chow, high-fat and high-cholesterol diet (HC, T3, or T6 (HC with thymol supplementation at 3 mg/kg/d or 6 mg/kg/d, respectively for 8 weeks. Aortic intimal thickening, serum lipid parameters, multiple inflammatory markers, proinflammatory cytokines, and atherosclerosis-associated indicators were significantly increased in the HC group but decreased upon thymol supplementation. In summary, thymol exhibits antioxidant activity, and may suppress the progression of high-fat-diet-induced hyperlipidemia and atherosclerosis by reducing aortic intimal lipid lesion, lowering serum lipids and oxidative stress, and alleviating inflammation-related responses.

    The aim of this study was to investigate a possible role for interleukin-6 (IL-6) and tumour necrosis factor (TNF-alpha) as pre-operative markers for the diagnosis of ovarian torsion. Twenty consecutive patients admitted to the gynaecological emergency room with suspected clinical diagnosis of ovarian torsion were prospectively assigned to the study. Blood samples were drawn pre-operatively and examined for serum concentrations of IL-6 and TNF-alpha. Surgeons were blinded to laboratory results prior to laparoscopy. The pre-operative diagnosis of ovarian torsion was confirmed during an urgent diagnostic laparoscopy in 8 (40%) patients. The surgical diagnosis among the remaining 12 patients was a large ovarian cyst not in torsion. In six out of eight (75.0%) patients with ovarian torsion serum IL-6 concentrations were elevated. None of the 12 patients without torsion had elevated serum IL-6 concentrations. This difference was statistically significant (P < 0.001). There was no significant difference in the proportion of women with elevated serum TNF-alpha concentrations, two of eight (25.0%) patients with torsion and four of 12 (33.3%) control cases. Elevated serum IL-6 concentrations, but not serum TNF-alpha concentrations, were significantly associated with the occurrence of ovarian torsion. In patients with vague clinical signs of ovarian torsion, serum IL-6 might help to distinguish which patients should undergo diagnostic laparoscopy.

    2013-01-01

    Full Text Available Obesity is a public health problem that has reached epidemic proportions with an increasing worldwide prevalence. The global emergence of obesity increases the risk of developing chronic metabolic disorders. Thus, it is an economic issue that increased the costs of the comorbidities associated. Moreover, in recent years, it has been demonstrated that obesity is associated with chronic systemic inflammation, this status is conditioned by the innate immune system activation in adipose tissue that promotes an increase in the production and release of pro-inflammatory cytokines that contribute to the triggering of the systemic acute-phase response which is characterized by elevation of acute-phase protein levels. On this regard, low-grade chronic inflammation is a characteristic of various chronic diseases such as metabolic syndrome, cardiovascular disease, diabetes, hypertension, non-alcoholic fatty liver disease, and some cancers, among others, which are also characterized by obesity condition. Thus, a growing body of evidence supports the important role that is played by the inflammatory response in obesity condition and the pathogenesis of chronic diseases related.

    Objective: To investigate the clinical value of detecting breast cancer with 3 imaging techniques(Ultrasound, Full-field digital mammography, Magnetic resonance imagery) and serum marker CA15-3. Methods: Sixty-six pathologically proven patients with breast cancer were examined with Ultrasound before operation, 58 cases were examined with Full-field digital mammography, 30 cases were examined by Magnetic resonance imagery, the serum marker CA15-3 was detected with CLIA in 58 cases. Results: The accurate rates of US, MO and MRI for diagnosis of breast cancer were respectively significantly higher than that of CA15-3(P 0.05) (the accuracy of US was 86.4%, the accuracy of MO was 93.2%, the accuracy of MRI was 96.7%). Conclusion: Ultrasonography,due to its reasonably good accuracy with very low cost, might be selected as the first choice of non-invasive diagnosis of breast cancer. (authors)

    It has been demonstrated that physical training increases serum brain-derived neurotrophic factor (BDNF) in healthy people. The aim of this study was to establish the effect of physical training on the basal serum level of the BDNF in the Parkinson's disease patients (PD patients) in relation to their health status. Twelve PD patients (mean ± S.E.M: age 70 ± 3 years; body mass 70 ± 2 kg; height 163 ± 3 cm) performed a moderate-intensity interval training (three 1-hour training sessions weekly), lasting 8 weeks. Basal serum BDNF in the PD patients before training amounted to 10,977 ± 756 pg x mL(-1) and after 8 weeks of training it has increased to 14,206 ± 1256 pg x mL(-1) (i.e. by 34%, P=0.03). This was accompanied by an attenuation of total Unified Parkinson's Disease Rating Scale (UPDRS) (P=0.01). The training resulted also in a decrease of basal serum soluble vascular cell adhesion molecule 1 (sVCAM-1) (P=0.001) and serum tumor necrosis factor-α (TNF-α) (P=0.03) levels. We have concluded that the improvement of health status of the Parkinson's disease patients after training could be related to the increase of serum BDNF level caused by the attenuated inflammation in those patients.

    Serum ferritin (SF) concentration as determined by the immunoradiometric method allows the direct measurement of a fraction of the body ferritin pool. In normal subjects, SF is an excellent index of body iron stores. In certain conditions associated with increased ferritin synthesis (such as liver disease, inflammation, malignancy, chronic disorders, ineffective erythropoiesis, or during ferrotherapy), SF may not accurately reflect body iron stores. In hyposideremic anemias SF concentration permits to differentiate those due to iron deficiency from those due to chronic disorders. With a good assay quality, subnormal SF levels are incontrovertible in the diagnosis of iron deficiency. SF determination has been investigated as possible tumor marker. When performed in combination with the alpha-fetoprotein assay, SF enhances the specificity of serodiagnosis of hepatoma. SF results must be interpreted bearing in mind the possible participation of circumstances that i) modify the body iron stores and ii) lead to increased ferritin synthesis. (author) [es

    The κ/λ hybrid antibodies in normal human serum were reported recently, but their clinical relevance has not yet been explored. Rheumatoid arthritis (RA) is one of the major joint diseases, and the early diagnosis and treatment of RA remain a challenge. Here, we developed a double-sandwich enzyme-linked immunosorbent assay system to quantify relative serum κ/λ hybrid antibody levels in RA patients, osteoarthritis (OA) patients, and healthy controls (HC) in order to assess their potential use as a serological biomarker of early disease and clinical activity and to preliminarily investigate their immunomodulatory roles in RA. Surprisingly, we found that κ/λ hybrid antibody was markedly increased in both early and established RA. Serum κ/λ hybrid antibody levels were significantly correlated with clinical indexes and inflammatory markers in RA. Further analysis showed a positive correlation between κ/λ hybrid antibody levels and the 28-joint disease activity score (DAS28). In conclusion, serum κ/λ hybrid antibodies in RA were identified for the first time. High levels of κ/λ hybrid antibody may be a useful tool in distinguishing early RA from OA and HC. We suggest κ/λ hybrid antibody as a marker for disease activity. The increased κ/λ hybrid antibodies were associated with inflammatory conditions in RA.

    The Eosinophil is a major cellular component in the late allergic response. In its activated state, the Eosinophil liberates performed basic proteins; the most sensitively quantifiable of them is the Eosinophil cationic protein (ECP).In the present study ECP was measured in tear and serum in different forms of ocular allergy to assess its value as a marker of disease severity and usefulness to evaluate topical therapy.Tears and serum were collected from 65 patients with allergic Keratoconjunctivitis, 20 healthy volunteers (6 of them children) with no history or evidence of allergic diseases, as well as, 5 patients with non allergic and untreated blepharo-conjunctivitis. Patients were classified according to their clinical signs and symptoms into four groups:Seasonal allergic conjunctivitis (SAC), 15 patients, Vernal Keratoconjunctivitis (VKC), 15 Palpebral and 6 Limbal, Atopic Keratoconjunctivitis (AKC), 17 patients and, Giant papillary conjunctivitis (GPC), 8 contact lens-induced and 4 suture-induced.Tears were collected by capillary tubes for cytological examination and measurement of ECP using radioimmunoassay methods. Serum was collected for measurement of ECP and atopy screening.Tear-ECP evaluation showed statistically significant elevation in all allergic subjects (p<0.001). Patients with VKC and AKC had significantly higher tear ECP values than patients with GPC and SAC. There was significant correlation between tear ECP values and disease severity.On the contrary, serum ECP values were only elevated significantly in atopic patients, and did not correlate to tear ECP values. Tear cytology was not sensitive to evaluate disease severity. These data demonstrated that tear ECP in contrast to serum ECP is a useful marker for disease severity in allergic ocular diseases and as such could become a valuable objective variable in treatment studies and as an adjunctive diagnostic tool in chronic conditions

    Full Text Available C-reactive protein (CRP levels are associated with cardiovascular disease and systemic inflammation. We assessed whether CRP-associated loci were associated with serum CRP and retinal markers of microvascular disease, in Asian populations.Genome-wide association analysis (GWAS for serum CRP was performed in East-Asian Chinese (N = 2,434 and Malays (N = 2,542 and South-Asian Indians (N = 2,538 from Singapore. Leveraging on GWAS data, we assessed, in silico, association levels among the Singaporean datasets for 22 recently identified CRP-associated loci. At loci where directional inconsistencies were observed, quantification of inter-ethnic linkage disequilibrium (LD difference was determined. Next, we assessed association for a variant at CRP and retinal vessel traits [central retinal artery equivalent (CRAE and central retinal vein equivalent (CRVE] in a total of 24,132 subjects of East-Asian, South-Asian and European ancestry.Serum CRP was associated with SNPs in/near APOE, CRP, HNF1A and LEPR (p-values ≤4.7×10(-8 after meta-analysis of Singaporean populations. Using a candidate-SNP approach, we further replicated SNPs at 4 additional loci that had been recently identified to be associated with serum CRP (IL6R, GCKR, IL6 and IL1F10 (p-values ≤0.009, in the Singaporean datasets. SNPs from these 8 loci explained 4.05% of variance in serum CRP. Two SNPs (rs2847281 and rs6901250 were detected to be significant (p-value ≤0.036 but with opposite effect directions in the Singaporean populations as compared to original European studies. At these loci we did not detect significant inter-population LD differences. We further did not observe a significant association between CRP variant and CRVE or CRAE levels after meta-analysis of all Singaporean and European datasets (p-value >0.058.Common variants associated with serum CRP, first detected in primarily European studies, are also associated with CRP levels in East-Asian and South

We assessed whether CRP-associated loci were associated with serum CRP and retinal markers of microvascular disease, in Asian populations.

Leveraging on GWAS data, we assessed, in silico, association levels among the Singaporean datasets for 22 recently identified CRP-associated loci. At loci where directional inconsistencies were observed, quantification of inter-ethnic linkage disequilibrium (LD) difference was determined. Next, we assessed association for a variant at CRP and retinal vessel traits [central retinal artery equivalent (CRAE) and central retinal vein equivalent (CRVE)] in a total of 24,132 subjects of East-Asian, South-Asian and European ancestry. Results Serum CRP was associated with SNPs in/near APOE, CRP, HNF1A and LEPR (p-values ≤4.7×10−8) after meta-analysis of Singaporean populations. Using a candidate-SNP approach, we further replicated SNPs at 4 additional loci that had been recently identified to be associated with serum CRP (IL6R, GCKR, IL6 and IL1F10) (p-values ≤0.009), in the Singaporean datasets. SNPs from these 8 loci explained 4.05% of variance in serum CRP. Two SNPs (rs2847281 and rs6901250) were detected to be significant (p-value ≤0.036) but with opposite effect directions in the Singaporean populations as compared to original European studies. At these loci we did not detect significant inter-population LD differences. We further did not observe a significant association between CRP variant and CRVE or CRAE levels after meta-analysis of all Singaporean and European datasets (p-value >0.058). Conclusions Common variants associated with serum CRP, first detected in primarily European studies, are also associated with

    BACKGROUND Markers of systemic inflammation (high-sensitivity C-reactive protein [hsCRP], soluble intercellular adhesion molecule 1 [sICAM-1], and fibrinogen) have been associated with a greater risk of total and ischemic stroke, in addition to elevated blood pressure. However, the role of these inflammatory markers on stroke pathophysiology by hypertension status is uncertain. METHODS Blood samples were collected and assayed for hsCRP, sICAM-1, and fibrinogen among 27,330 initially healthy women from the Women’s Health Study, and women were followed up from 1992 to 2013. Prior to randomization, the baseline questionnaire collected self-reported hypertension status, cardiovascular risk factors, and lifestyle factors. New cases of total, ischemic, and hemorrhagic stroke were updated annually through questionnaires and confirmed by medical records according to the National Survey of Stroke criteria. Multivariable Cox models estimated overall associations between each inflammatory marker and stroke and separately stratified by hypertension status. RESULTS We observed 629 incident total strokes over 477,278 person-years. In adjusted analyses, extreme quartiles of hsCRP and sICAM-1 were each associated with a significantly greater risk of total stroke (hsCRP: hazard ratios [HR] = 1.77, 95% confidence interval [CI]: 1.39–2.26; sICAM-1: HR = 1.28, 95% CI: 1.00–1.63). Fibrinogen was not associated with a significantly greater stroke risk. In analyses stratified by hypertension status, elevated hsCRP was associated with a nonstatistically significant greater risk of total stroke among prehypertensive and hypertensive women. CONCLUSIONS These data indicate that hsCRP and sICAM-1 are associated with hypertension status and stroke risk among women. Further work should examine the role of inflammatory markers on ischemic stroke subtypes and clarify mechanisms. PMID:27235695

    The purpose of this study was to explore body fat independent effect of second generation antipsychotics (SGAs) on measures of glucose and adipokine homeostasis, and markers of inflammation. Eight non-diabetic men with schizophrenia (age: 55±3years, BMI: 29.7±1.2kg/m(2)) on SGAs were studied after an overnight fast. DXA and single-cut CT of abdomen were respectively used for the assessment of total body and abdominal fat. Blood samples were collected for measurements of glucose, insulin, leptin, adiponectin, C-reactive protein (CRP), and TNF-α. Data in schizophrenic subjects were compared to eight age (55±2.8years) and BMI (29.6±1.1kg/m(2)) matched healthy men. The results were significant for markedly decreased serum adiponectin in schizophrenia patients (4.6±0.9 vs 11.1±1.5ng/mL, p=0.001). Lower levels of adiponectin in schizophrenia men were associated with significant increases in insulin resistance (4.2±0.7 vs 1.7±0.4, p=0.004), CRP (3.5±1.2 vs 1.2±0.3, p=0.037), and leptin (12±1.4 vs 8.5±1.4ng/mL, p=0.05). Various measures of adiposity, including fat mass index (FMI) and abdominal fat were not different in the two study groups. These findings in the context of comparable age and total body/abdominal fat mass are assumed to be either disease specific, and/or treatment inflicted. The definitive invoking etiology and a presumptive role of hypoadiponectinemia in the development of insulin resistance and increased risk of inflammation warrant future investigation.

    Objective: To study the usefulness of monitoring changes of serum levels of tumor markers (CEA, CA15-3 and CA125) for assessment of efficacy of chemotherapy in patients with breast cancer. Methods: Serum CEA, CA15-3 and CA125 levels were measured with CLIA three days before beginning 1st course of appropriate chemotherapy and 3 weeks after completing 2nd course of treatment in 45 patients with advanced breast cancer (TNM stage III, n=20, stage IV n=25). Results: Expressed as CR, PR, SD and PD as defined by the changes of serum tumor markers levels (according to Bac D.J. et al) were compared with clinically observed ones (WHO standard). The serum levels of Cea, CA15-3 decreased markedly in the CR and PR groups of patients but increased markedly in PD patients (P 0.05). The coincidence rate between the results observed clinically and results derived from tumor marker changes was 50.0% for CEA, 55.6% for CA15-3, 31.1% for CA125 and 73% for three markers combined. Conclusion: Combined determination of the changes of serum levels of three tumor marker would help to make a reasonably satisfactory assessment of efficacy of chemotherapy in patients with breast cancer.

    Chronic graft-versus-host disease (cGVHD) remains a major cause of non-relapse morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Currently there are no accepted measures of cGVHD activity to aid in clinical management and disease staging. We analyzed clinical markers of inflammation in the sera of patients with established cGVHD and correlated those with definitions of disease activity. In all, 189 adults with cGVHD (33% moderate and 66% severe according to National Institutes of Health (NIH) global scoring) were consecutively enrolled onto a cross-sectional prospective cGVHD natural history study. At the time of evaluation, 80% were receiving systemic immunosuppression and failed a median of four prior systemic therapies (PST) for their cGVHD. Lower albumin (P<0.0001), higher C-reactive protein (P = 0.043), higher platelets (P = 0.030) and higher number of PST (P<0.0001) were associated with active disease defined as clinician's intention to intensify or alter systemic therapy due to the lack of response. Higher platelet count (P = 0.021) and higher number of PST (P<0.0001) were associated with more severe diseased defined by NIH global score. This study identified common laboratory indicators of inflammation that can serve as markers of cGVHD activity and severity.

    Objective: To explore the relationship between rheumatoid activity and serum levels of the cytokines interleukin-2 (IL-2), soluble interleukin-2 receptor (sIL-2R), hyaluronic acid (HA), vascular endothelial growth factor (VEGF) in patients with rheumatoid arthritis. Methods: Serum IL-2, HA(with RIA) and sIL-2R, VEGF (with ELISA) levels were determined in 30 controls, 30 patients with active rheumatoid arthritis and 30 patients with rheumatoid arthritis in remission. Sensitivity and specificity for each marker were analyzed. Results: In patients with active rheumatoid arthritis, the serum levels of sIL-2R, HA, VEGF were significantly higher and serum levels of IL-2 significantly lower than those in patients in remission and controls (p<0.01). Determination of VEGF levels possessed the highest specificity (93.3%) and also a high sensitivity (93.3% as well). Conclusion: Determination of the serum levels of any of these markers was valuable for monitoring the activity of the rheumatoid process. It is more desirable to take measurements of VEGF levels due to its highest specificity

    Full Text Available INTRODUCTION Polycystic ovary syndrome (PCOS is one of the most common causes of anovulation, infertility and hyperandrogenism, and the prevalence of this condition in women of reproductive is 5-10%. The growth of early ovarian antral follicles is arrested and dominant follicle selection is disturbed in this syndrome. OBJECTIVE The aim of this study is to investigate whether inhibin B serum concentrations represent the extent of ovarian abnormalities in patients with PCOS. METHOD Inhibin B serum concentrations on the third day of spontaneous menstrual cycle and other endocrine characteristics were compared between 20 patients with PCOS and 19 healthy women in the control group. RESULTS Inhibin B concentrations were not significantly different between women with PCOS and women in the control group. In patients with PCOS there was statistically significant correlation between serum inhibin B and LH (r=0.514; p=0.021. There were no positive correlations between inhibin B and others endocrine parameters in patients with PCOS (FSH, E2, T, androstenedione. CONCLUSION Inhibin B serum concentrations on the third day of spontaneous menstrual cycle in women with PCOS are not different from the concentrations in healthy women. Serum Inhibin B levels in patients with PCOS are only slightly correlated with the endocrine markers of the disease so it could not represent the magnitude of ovarian dysfunction in this syndrome.

    Objective: To study the clinical value of serum tumor marker determination and whole body bone scan for diagnosis of bone metastases from breast cancer. Methods: Serum tumor markers (CA15-3, CEA, TSGF)were detected with GLIA and whole body bone scan were investigated by SPECT in 124 breast cancer patients. Results: In 124 patients, 38 patients were diagnosed as positive for bone metastases with whole body bone scan. The positive predicting values of CA15-3, CEA, TSGF were 76.78%, 80% and 82.14%, and the negative predicting values of CA15-3, GEA, TSGF were 82.41%, 86.74% and 84.29% respectively. The levels of CA15-3, CEA, TSGF in patients with bone metastases were significantly higher than those in patients without metastasis and the controls (P<0.01). Conclusion: Determination of levels of serum tumor markers CA15-3, CEA, TSGF is helpful for diagnosis of bone metastases from breast cancer. Combined detection of GA15-3, CEA, TSGF could increase the sensitivity and accuracy of diagnosing bone metastases. (authors)

    COPD (chronic obstructive pulmonary disease) is defined by a fixed expiratory airflow obstruction associated with disordered airways and alveolar destruction. COPD is caused by cigarette smoking and is the third greatest cause of mortality in the US. Forced expiratory volume in 1 second (FEV1) is the only validated clinical marker of COPD, but it correlates poorly with clinical features and is not sensitive enough to predict the early onset of disease. Using LC/MS global untargeted metabolite profiling of serum samples from a well-defined cohort of healthy smokers (n = 37), COPD smokers (n = 41) and non-smokers (n = 37), we sought to discover serum metabolic markers with known and/or unknown molecular identities that are associated with early-onset COPD. A total of 1,181 distinct molecular ions were detected in 95% of sera from all study subjects and 23 were found to be differentially-expressed in COPD-smokers vs. healthy-smokers. These 23 putative biomarkers were differentially-correlated with lung function parameters and used to generate a COPD prediction model possessing 87.8% sensitivity and 86.5% specificity. In an independent validation set, this model correctly predicted COPD in 8/10 individuals. These serum biomarkers included myoinositol, glycerophopshoinositol, fumarate, cysteinesulfonic acid, a modified version of fibrinogen peptide B (mFBP), and three doubly-charged peptides with undefined sequence that significantly and positively correlate with mFBP levels. Together, elevated levels of serum mFBP and additional disease-associated biomarkers point to a role for chronic inflammation, thrombosis, and oxidative stress in remodeling of the COPD airways. Serum metabolite biomarkers offer a promising and accessible window for recognition of early-stage COPD. PMID:26674646

    Background: Diet and smoking are the main sources of cadmium exposure in the general population. Cadmium increases the risk of cardiovascular diseases, and experimental studies show that it induces inflammation. Blood cadmium levels are associated with macrophages in human atherosclerotic plaques. Soluble urokinase-type plasminogen activator receptor (suPAR) is an emerging biomarker for cardiovascular events related to inflammation and atherosclerotic plaques. The aim was to examine whether blood cadmium levels are associated with circulating suPAR and other markers of inflammation. Methods: A population sample of 4648 Swedish middle-aged women and men was examined cross-sectionally in 1991–1994. Plasma suPAR was assessed by ELISA, leukocytes were measured by standard methods, and blood cadmium was analysed by inductively coupled plasma mass spectrometry. Prevalent cardiovascular disease, ultrasound-assessed carotid plaque occurrence, and several possible confounding factors were recorded. Results: After full adjustment for risk factors and confounding variables, a 3-fold increase in blood cadmium was associated with an 10.9% increase in suPAR concentration (p<0.001). In never-smokers, a 3-fold increase in blood cadmium was associated with a 3.7% increase in suPAR concentration (p<0.01) after full adjustment. Blood cadmium was not associated with C-reactive protein, white blood cell count and Lp-PLA2 but with neutrophil/lymphocyte ratio in one of two statistical models. Conclusions: Exposure to cadmium was associated with increased plasma suPAR in the general population, independently of smoking and cardiovascular disease. These results imply that cadmium is a possible cause for raised levels of this inflammatory marker. - Highlights: • Cadmium is a toxic proinflammatory, proatherosclerotic metal. • Soluble urokinase-type plasminogen activator receptor (suPAR) in plasma is a promising proinflammatory marker of atherosclerosis. • Blood cadmium and plasma su

    The aim of this study was to investigate the effects of ginger supplementation on serum glucose, advanced glycation end products, oxidative stress, and systemic and vascular inflammatory markers in patients on peritoneal dialysis (PD). In this randomized, double-blind, placebo-controlled trial, 36 patients on PD were randomly assigned to either the ginger or the placebo group. The patients in the ginger group received 1000 mg/d ginger for 10 wk, whereas the placebo group received corresponding placebos. At baseline and the end of week 10, serum concentrations of glucose, carboxymethyl lysine, pentosidine, malondialdehyde (MDA), high-sensitivity C-reactive protein (hs-CRP), soluble intercellular adhesion molecule type 1 (sICAM-1), soluble vascular cell adhesion molecule type 1 (sVCAM-1), and sE-selectin were measured after a 12- to 14-h fast. Serum fasting glucose decreased significantly up to 20% in the ginger group at the end of week 10 compared with baseline (P ginger reduces serum fasting glucose, which is a risk factor for hyperinsulinemia, dyslipidemia, peritoneal membrane fibrosis, and cardiovascular disease, in patients on PD.

    Objective: To explore the clinical significance of changes of serum bone metabolic biochemical markers levels in elderly subjects with subclinical hypothyroidism. Methods: Serum S-BGP (with RIA), TSH, FT 4 (with ECLIA), total cholesterol (TC), triglyceride (TG), HDL, LDL, ApoA 1 , ApoB and Ca 2+ (with biochemical methods) were measured in 30 elderly subjects with subclinical hypothyroidism and 30 controls. Results: The serum levels of S-BGP and calcium in elderly subjects with subclinical hypothyroidism (2.78 ± 0.96 μg/L and 2.16 ± 0.17 mmol/L respectively) were significantly lower than those in controls (3.9 ± 1.48 μg/L and 2.31 ± 0.21 mmol/L respectively, both P<0.01). TC and LDL levels in the subclinical hypothyroid subjects (5.58 ± 0.41 mmol/L and 3.67 ± 0.36 mmol/L) were significantly higher than those in controls (P<0.01). Conclusion: The lowering of calcium levels in subjects with subclinical hypothyroidism would lead to loss of bone mass. Decreased S-BGP contents might be the chief cause of osteoporosis in these subjects. (authors)

    2010-01-01

    Background Bronchial Hyperresponsiveness (BHR) is considered a hallmark of asthma. Other methods are helpful in epidemiological respiratory health studies including Fractional Exhaled Nitric Oxide (FENO) and Eosinophils Percentage (EP) in nasal lavage fluid measuring markers for airway inflammation along with the Forced Oscillatory Technique measuring Airway resistance (AR). Can their outcomes discriminate profiles of respiratory health in healthy subjects starting apprenticeship in occupations with a risk of asthma? Methods Rhinoconjunctivitis, asthma-like symptoms, FEV1 and AR post-Methacholine Bronchial Challenge (MBC) test results, FENO measurements and EP were all investigated in apprentice bakers, pastry-makers and hairdressers not suffering from asthma. Multiple Correspondence Analysis (MCA) was simultaneously conducted in relation to these groups and this generated a synthetic partition (EI). Associations between groups of subjects based on BHR and EI respectively, as well as risk factors, symptoms and investigations were also assessed. Results Among the 441 apprentice subjects, 45 (10%) declared rhinoconjunctivitis-like symptoms, 18 (4%) declared asthma-like symptoms and 26 (6%) suffered from BHR. The mean increase in AR post-MBC test was 21% (sd = 20.8%). The median of FENO values was 12.6 ppb (2.6-132 range). Twenty-six subjects (6.7%) had EP exceeding 14%. BHR was associated with atopy (p < 0.01) and highest FENO values (p = 0.09). EI identified 39 subjects with eosinophilic inflammation (highest values of FENO and eosinophils), which was associated with BHR and atopy. Conclusions Are any of the identified markers predictive of increased inflammatory responsiveness or of development of symptoms caused by occupational exposures? Analysis of population follow-up will attempt to answer this question. PMID:20604945

    Allergic and atopic disorders have increased over the past few decades and have been associated with neuropsychiatric conditions, such as autism spectrum disorder and asthmatic amyotrophy. Myelitis presenting with neuropathic pain can occur in patients with atopic disorder; however, the relationship between allergic inflammation and neuropathic pain, and the underlying mechanism, remains to be established. We studied whether allergic inflammation affects the spinal nociceptive system. We found that mice with asthma, atopic dermatitis, or atopic diathesis had widespread and significantly more activated microglia and astroglia in the spinal cord than those without atopy, and displayed tactile allodynia. Microarray analysis of isolated microglia revealed a dysregulated phenotype showing upregulation of M1 macrophage markers and downregulation of M2 markers in atopic mice. Among the cell surface protein genes, endothelin receptor type B (EDNRB) was most upregulated. Immunohistochemical analysis revealed that EDNRB expression was enhanced in microglia and astroglia, whereas endothelin-1, an EDNRB ligand, was increased in serum, lungs, and epidermis of atopic mice. No EDNRA expression was found in the spinal cord. Expression of FBJ murine osteosarcoma viral oncogene homolog B was significantly higher in the dorsal horn neurons of asthma mice than nonatopic mice. The EDNRB antagonist BQ788 abolished glial and neural activation and allodynia. We found increased serum endothelin-1 in atopic patients with myelitis and neuropathic pain, and activation of spinal microglia and astroglia with EDNRB upregulation in an autopsied case. These results suggest that allergic inflammation induces diffuse glial activation, influencing the nociceptive system via the EDNRB pathway. The prevalence of allergic disorders has markedly increased over the past few decades. Allergic disorders are associated with neuropsychiatric conditions; however, the relationship between allergic inflammation

    Visfatin, a protein secreted by adipose tissue, is suggested to play a role in pathogenesis of insulin resistance. In polycystic ovary syndrome (PCOS), insulin resistance might be involved in the development of endocrine and metabolic abnormalities. The aim of the study was to asses the relation between serum visfatin concentration and insulin sensitivity and markers of hyperandrogenism in lean and obese PCOS patients. The study group consisted of 70 women with PCOS (23 lean and 47 obese) and 45 healthy women (25 lean and 20 obese). Euglycemic hyperinsulinemic clamp and the measurements of serum visfatin, sex hormones were performed. The PCOS group had lower insulin sensitivity (P=0.00049) and higher serum visfatin (P=0.047) in comparison to the control group. The decrease in insulin sensitivity was present in both the lean (P=0.019) and obese (P=0.0077) PCOS subjects, whereas increase in serum visfatin was observed only in lean PCOS subjects (P=0.012). In the whole group, serum visfatin was negatively correlated with insulin sensitivity (r=-0.27, P=0.004). This relationship was also observed in the subgroup of lean (r=-0.30, P=0.038), but not obese women. Additionally, in lean women, visfatin was associated with serum testosterone (r=0.47, P=0.002) and free androgen index (r=0.48, P=0.002), independently of other potential confounding factors. Visfatin is associated with insulin resistance and markers of hyperandrogenism in lean PCOS patients.

    Full Text Available The κ/λ hybrid antibodies in normal human serum were reported recently, but their clinical relevance has not yet been explored. Rheumatoid arthritis (RA is one of the major joint diseases, and the early diagnosis and treatment of RA remain a challenge. Here, we developed a double-sandwich enzyme-linked immunosorbent assay system to quantify relative serum κ/λ hybrid antibody levels in RA patients, osteoarthritis (OA patients, and healthy controls (HC in order to assess their potential use as a serological biomarker of early disease and clinical activity and to preliminarily investigate their immunomodulatory roles in RA. Surprisingly, we found that κ/λ hybrid antibody was markedly increased in both early and established RA. Serum κ/λ hybrid antibody levels were significantly correlated with clinical indexes and inflammatory markers in RA. Further analysis showed a positive correlation between κ/λ hybrid antibody levels and the 28-joint disease activity score (DAS28. In conclusion, serum κ/λ hybrid antibodies in RA were identified for the first time. High levels of κ/λ hybrid antibody may be a useful tool in distinguishing early RA from OA and HC. We suggest κ/λ hybrid antibody as a marker for disease activity. The increased κ/λ hybrid antibodies were associated with inflammatory conditions in RA.

    Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. Autoimmune inflammation is common in the early stages of MS. This stage is followed by the neurodegenerative process. The result of these changes is axon and myelin breakdown. Although MS is according to McDonald's revised diagnostic criteria primarily a clinical diagnosis, paraclinical investigation methods are an important part in the diagnosis of MS. In common practice, magnetic resonance imaging of the brain and spinal cord, examination of cerebrospinal fluid (CSF) and examination of visual evoked potentials are used. There are an increasing number of studies dealing with biomarkers in CSF and their role in the diagnosis and treatment of MS. We hypothesized that the levels of some markers could be changed in MS in comparison with controls. We studied five inflammatory markers [interleukin-6 (IL-6), interleukin-8, interleukin-10 (IL-10), beta-2-microglobulin, orosomucoid]. CSF and serum levels of inflammatory markers were assessed in 38 patients with newly diagnosed MS meeting McDonald's revised diagnostic criteria and in 28 subjects as a control group (CG). Levels of beta-2-microglobulin and interleukin-8 in CSF were found to be significantly higher in MS patients in comparison to CG (p < 0.001 resp. p = 0.007). No differences in other CSF markers (IL-6, IL-10 and orosomucoid) and serum levels of all markers between both groups were found. The levels of two studied inflammatory markers were found to be increased at the time of first clinical symptoms of MS. Research on the role of inflammatory and neurodegenerative markers in MS should continue.

    Full Text Available Studies in humans and animal models link maternal infection and imbalanced levels of inflammatory mediators in the foetal brain to the aetiology of neuropsychiatric disorders. In a number of animal models, it was shown that exposure to viral or bacterial agents during a period that corresponds to the second trimester in human gestation triggers brain and behavioural abnormalities in the offspring. However, little is known about the early cellular and molecular events elicited by inflammation in the foetal brain shortly after maternal infection has occurred. In this study, maternal infection was mimicked by two consecutive intraperitoneal injections of 200 μg of LPS (lipopolysaccharide/kg to timed-pregnant rats at GD15 (gestational day 15 and GD16. Increased thickness of the CP (cortical plate and hippocampus together with abnormal distribution of immature neuronal markers and decreased expression of markers for neural progenitors were observed in the LPS-exposed foetal forebrains at GD18. Such effects were accompanied by decreased levels of reelin and the radial glial marker GLAST (glial glutamate transporter, and elevated levels of pro-inflammatory cytokines in maternal serum and foetal forebrains. Foetal inflammation elicited by maternal injections of LPS has discrete detrimental effects on brain development. The early biochemical and morphological changes described in this work begin to explain the sequelae of early events that underlie the neurobehavioural deficits reported in humans and animals exposed to prenatal insults.

    Hepcidin has emerged as a peptide with a key role in the regulation of iron homeostasis in patients with chronic kidney disease (CKD), having a strong dependence on inflammation. Recent studies reveal that hepcidin may be also associated with the progression of atherosclerosis. This study was performed to analyze the relation of hepcidin to markers of atherosclerosis and inflammation in patients on dialysis. A total of 90 individuals were enrolled. Sixty patients with end-stage renal disease, who were on hemodialysis (HD) (N = 30) and peritoneal dialysis (N = 30) were compared with 30 normal controls (NC). Age, body mass index, time on dialysis, serum lipids, C-reactive protein (CRP) and interleukin-6 (IL-6) were measured and analyzed in correlation with hepcidin concentration. It was found that patients on HD and peritoneal dialysis have significantly higher (P triglycerides (r = 0.401, P = 0.005), HDL-C (r = -0.268, P = 0.048), CRP (r = 0.436, P = 0.0007) and IL-6 (r = 0.569, P triglycerides (β = 0.402, P = 0.041) and IL-6 (β = 0.559, P = 0.006). Moreover, patients with high triglycerides in combination with high IL-6 levels have significantly increased concentrations of hepcidin than those with low triglycerides and low IL-6 levels (P triglycerides and high IL-6 serum concentrations. This probably suggests that hepcidin may play a role to the progression of atherosclerosis and inflammation, but this hypothesis should be further evaluated. © 2013 The Authors.

    The purpose of this study was to examine the effects of resistance training (RT) and dried plum (DP) consumption on strength, body composition, blood markers of bone, and inflammation in breast cancer survivors (BCS). Twenty-three BCS (RT, n = 12; RT+DP, n = 11), aged 64 ± 7 years, were evaluated at baseline and after 6 months of intervention on the following: muscular strength (chest press and leg extension) via 1-repetition maximums (1RMs); body composition, specifically bone mineral density (BMD) by dual energy X-ray absorptiometry; biochemical markers of bone turnover (bone-specific alkaline phosphatase (BAP), tartrate resistant acid phosphatase (TRAP-5b)); and inflammation (C-reactive protein (CRP)). Target RT prescription was 2 days/week of 10 exercises, including 2 sets of 8-12 repetitions at ∼60%-80% of 1RM. RT+DP also consumed 90 g of DP daily. There were no baseline differences between groups or any group-by-time interactions for any of the variables. BCS increased upper (p body strength. Body composition and BMD improvements were not observed. TRAP-5b decreased in the RT group (p body composition and biochemical markers of inflammation.

    We sought to investigate the hypothesis that smoking is accompanied by systemic inflammation. We examined the relation of smoking to 11 systemic inflammatory markers in Framingham Study participants (n=2944, mean age 60 years, 55% women, 12% ethnic minorities) examined from 1998-2001. The cohort was divided into never (n=1149), former (n=1424), and current smokers with last cigarette >6h (n=134) or < or =6h (n=237) prior to phlebotomy. In multivariable-adjusted models there were significant overall between-smoking group differences (defined as p<0.0045 to account for multiple testing) for every inflammatory marker tested, except for serum CD40 ligand (CD40L), myeloperoxidase (MPO) and tumor necrosis factor receptor-2 (TNFR2). With multivariable-adjustment, pair-wise comparisons with never smokers revealed that former smokers had significantly lower concentrations of plasma CD40L (p<0.0001) and higher concentrations of (CRP) C-reactive protein (p=0.002). As opposed to never smokers, those with acute cigarette smoke exposure (< or =6h) had significantly higher concentrations of all markers (p<0.0001) except serum CD40L, MPO, and TNFR2; plasma CD40L were significantly lower. Compared with never smokers, cigarette smokers have significantly elevated concentrations of most circulating inflammatory markers, consistent with the hypothesis that smoking is associated with a systemic inflammatory state.

    Full Text Available Objective: In view of the side effects of voiding cystourethrography (VCUG, identification of noninvasive markers predicting the presence of vesicoureteral reflux (VUR is important. This study was conducted to determine the predictive value of serum interleukin-8 (IL-8 in diagnosis of VUR in children with first febrile urinary tract infection (UTI. Materials and Methods: Eighty children with first febrile UTI were divided into two groups, with and without VUR, based on the results of VCUG. The sensitivity, specificity, positive and negative predictive value positive and negative likelihood ratio, and accuracy of IL-8 for prediction of VUR were investigated. Results: Of the 80 children with febrile UTI, 30 (37.5% had VUR. There was no significant difference between the children with and without VUR and also between low and high-grade VUR groups in terms of serum concentration of IL-8 (P>0.05. Based on ROC curve, the sensitivity, specificity, likelihood ratio positive, and accuracy of serum IL-8 was lower than those of erythrocyte sedimentation rate and C-reactive protein. Multivariate logistic regression analysis showed significant positive correlation only between erythrocyte sedimentation rate and VUR. Conclusions: This study showed no significant difference between the children with and without VUR in terms of the serum concentration of IL-8. Therefore, it seems that serum IL-8 is not a reliable marker for prediction of VUR.

    Since renal failure causes decrease in tumor marker excretion, use of these markers in cancer care and treatment in patients with renal insufficiency or hemodialysis is controversial. The aim of this study was to investigate differences of serum levels of tumor markers CA15-3, AFP, CA19-9 and CEA in patients with impaired renal function. A total of 100 patients referred to the Tabriz Immam Reza and Amiralmomenin hospital from June 2010 to November 2011 were selected for study. Subjects were divided to 3 groups of healthy, dialysis and renal failure but non hemodialysis cases, the last category being re-grouped based on creatinine clearance. No significant relationship between different groups in serum levels of CEA (P=0.99) and CA19-9 (P=0.29) tumor markers was found. A significant correlation was observed between serum levels of AFP (PCEA (r=0.05, P=0.625). Creatinine clearance significantly correlated with AFP (Ptumor markers in patients with impaired renal function should be performed with special precautions.

    Objective: The study was carried out to evaluate the role of serum eosinophil cationic protein (ECP) as a biological marker for the diagnosis and to assess the severity of bronchial asthma. Methodology: This observational cross-sectional study was conducted among 70 bronchial asthma patients and 45 disease controls (tuberculosis-15, chronic obstructive pulmonary disease-15, interstitial lung disease-15) enrolled from patients attending the outpatient department of the National Institute of Disease of the Chest and Hospital (NIDCH), Dhaka, Bangladesh during July 2010 to June 2011. Global Initiative of Asthma Management and Prevention (GINA) criteria were followed for selection of both atopic and non-atopic patients with intermittent or persistent (mild, moderate and severe) asthma. Serum level of eosinophil cationic protein (ECP), IgE, forced expiratory volume in 1 second (FEV 1% predicted) and circulatory eosinophil (CE) count were estimated. Results: Mean serum ECP level (28.8 +- 42.9 vs. 6.82 +- 3.5 ng/mL; P<0.001), IgE level (383.59 - 225.3 vs. 135 +- 131.8 IU/mL; P<0.001) and percent circulatory eosinophil count (9.95 +- 3.7 vs. 5.95 +- 1.4; P<0.024) were all found significantly raised among asthma patients than disease controls but % FEV1 was equivocal. All grades of persistent asthma patients had significantly (P<0.025 and P<0.002) higher mean ECP level than intermittent cases but serum IgE level and CE count did not differ significantly. FEV1 % predicted correlated well among moderate and severe persistent asthma but was equivocal for intermittent and mild persistent cases. Conclusion: This study has reinforced that serum eosinophil cationic protein is a dependable biological marker with more discriminatory power over other indicators for bronchial asthma and to assess its severity.

    Full Text Available Objective: To study the effect of surgical resection combined with transcatheter arterial chemoembolization (TACE on postoperative serum tumor marker levels and stem cell characteristics during tumor recurrence. Methods: A total of 98 patients with liver cancer who received radical resection in our hospital between May 2013 and July 2015 were reviewed and divided into TACE group and control group according to whether they received TACE within two months after surgical resection. Serum levels of tumor markers were detected 4 weeks after operation; the tumor recurrence was followed up within 3 years after operation, and the expression of stem cell marker molecules and cell proliferation molecules in recurrent lesions were detected. Results: 4 weeks after radical hepatectomy, serum AFP, AFP-L3, GP73 and GPC3 levels in TACE group were significantly lower than those in control group; Nanog, CD133, EpCAM, PICK1, CyclinD1, C-myc and Survivin expression in surgically removed lesions of TACE group were not different from those of control group while Nanog, CD133, EpCAM, PICK1, CyclinD1, C-myc and Survivin expression in recurrent lesions were significantly lower than those of control group. Conclusion: Surgical resection combined with TACE can more effectively remove liver cancer lesions, reduce the tumor marker levels and inhibit the tumor stem cell characteristics and cell proliferation activity in recurrent lesions.

    After the GINA 2006 publication, asthma therapy is based on control of symptoms. However there are suggestions of monitoring of airway inflammation. Aim of the study was to compare clinical criteria of asthma control with cellular markers of lower airway inflammation in induced sputum in a group of young asthmatics. To assess relationship between sputum eosinophilia, asthma severity and spirometry. A group of 154 young patients with chronic asthma (8-21 years) underwent sputum induction by inhalation of 4,5% saline solution. Sputum induction was effective in 121 patients (78%), and in this group control of clinical symptoms was assessed according to GINA 2006 criteria. Asthma was controlled in 82 subjects (67.8%) and uncontrolled in 39 (32.2%). Patients with controlled asthma had higher FEV1/FVC (79.8 +/- 7.1% vs 74.2 +/- 9.9%; p = 0.004) and MMEF (80.7 +/- 23.0% vs 65.3 +/- 21.8%; p 3%) was observed in 24.4% of patients with controlled asthma and in 61.5% with uncontrolled asthma (p astma than in patients with moderate-severe disease (3.1 +/- 5.7% vs 7.1% +/- 8.8; p = 0.006). Patients with high sputum eosinophil count had lower FEV1 (89.4 +/- 14.9% vs 94.9 +/- 13.9%; p = 0.047), FEV1/FVC (74.5 +/- 10.1% vs 79.2 +/- 9.3%; p = 0.01) and MMEF (68.7 +/- 23.3% vs 81.7 +/- 23.1%; p = 0.004). In this study of young asthmatics, control of asthma symptoms was observed in 67.8% of patients. However, cellular markers of lower airway inflammation were present in 1/4 of patients with controlled asthma and in 3/4 with uncontrolled disease. Sputum eosinophilia was related to asthma severity. FEV1/FVC and MMEF were more important that FEV1 for estimating control of asthma. Improvement of asthma control scoring is needed as well as availability of simple methods of inflammation monitoring.

    Oxidative stress is one of the key mechanisms responsible for disease progression in non-alcoholic fatty liver disease. The aim of this study was to evaluate the serum levels of oxidative stress markers in patients with type 2 diabetes mellitus (DMT2) and non-alcoholic steatohepatitis (NASH) and test their relationships with clinical and biochemical patient characteristics, compared to patients with DMT2 without non-alcoholic fatty liver disease (NAFLD), and controls. In all, 60 consecutive patients with DMT2 and NASH, 55 with DMT2 without NAFLD, and 50 age-and-gender-matched healthy subjects participated in the study. The serum levels of protein carbonyls and 8-isoprostane were determined by ELISA methods, while the serum levels of malondialdehyde (MDA) were detected by means of the spectrophotometric method. Clinical, demographic, and laboratory parameters were examined for all the subjects included in the study. Multivariate logistic regression was used to test the independent predictive factors in the relationships investigated here. Patients with DMT2 and NASH displayed significantly higher serum levels of protein carbonyls (1.112 ± 0.42 nmol/dL), MDA (6.181 ± 1.81 ng/mL), and 8-isoprostane (338.6 ± 98.5 pg/mL) compared to patients with DMT2 without NAFLD, and controls. Results of multivariate logistic regression analyses indicate that in patients with DMT2 and NASH, the serum levels of oxidative stress markers were independently and positively associated with: HbA1c, duration of diabetes, the UKPDS cardiovascular risk score (for protein carbonyls); age, LDL-cholesterol (for 8-isoprostane); and triglycerides serum levels (for MDA). Our findings indicate that the process of oxidative stress tends to increase in patients with DMT2 and NASH, compared to patients with DMT2 without NAFLD, and controls. This evidence suggests that an antioxidant therapy might prove useful in the treatment of patients with DMT2 and NASH.

    Schizophrenia is associated with atopy and increased inflammatory markers. We report a population-based longitudinal study of the associations between childhood atopic disorders, subsequent serum inflammatory markers, interleukin 6 (IL-6) and C-reactive protein (CRP), and the risk of psychotic experiences (PEs). PEs were assessed at age 13 years (n=6785). Presence of clinician-diagnosed atopic disorders (asthma and eczema) was determined from parent-completed questionnaires at age 10 years (n=7814). Serum IL-6 and CRP were measured at age 9 years (n=5076). Logistic regression examined the association between (1) atopy and PEs, (2) inflammatory markers and PEs, and (3) mediating effects of inflammatory markers on the atopy-PEs association. Linear regression examined the association between atopy and inflammatory markers. Age, gender, social class, ethnicity and body mass index were included as potential confounders. At age 10 years, about 14% of the sample was reported to have asthma, 12% eczema, and 7% both asthma and eczema. Compared with children with no atopy, risk of PEs at age 13 years was increased for all of these groups; adjusted odds ratios (95% CI) were, respectively, 1.39 (1.10-1.77), 1.33 (1.04-1.69), and 1.44 (1.06-1.94). Atopy was associated with increased serum IL-6 and CRP; however, this did not mediate association between atopy and PEs. Inflammatory markers were not associated with later PEs. Childhood atopic disorders increase the risk of psychotic experiences in adolescence. Follow-up of these individuals will be useful to determine the effect of atopy and inflammation on different trajectories of early-life PEs. © 2013. Published by Elsevier B.V. All rights reserved.

    Full Text Available The omega-3 fatty acid docosahexaenoic acid (DHA has anti-inflammatory and anti-nociceptive (pain inhibiting effects. Because strenuous exercise often results in local inflammation and pain, we hypothesized that DHA supplementation attenuates the rise in markers of local muscle inflammation and delayed onset muscle soreness (DOMS that occur after eccentric strength exercise. Twenty-seven, healthy women (33 ± 2 y, BMI 23.1±1.0 kg·m-2 were randomized to receive 9d of 3000 mg/d DHA or placebo in a double-blind fashion. On day 7 of the supplementation period, the participants performed 4 sets of maximal-effort eccentric biceps curl exercise. Before and 48h after the eccentric exercise, markers of inflammation were measured including measures of muscle soreness (10-point visual analog pain scale, VAS, swelling (arm circumference, muscle stiffness (active and passive elbow extension, skin temperature, and salivary C-reactive protein (CRP concentrations. As expected, muscle soreness and arm circumference increased while active and passive elbow extension decreased. The increase in soreness was 23% less in the DHA group (48h increase in VAS soreness ratings: 4.380.4 vs. 5.600.5, p=0.02. Furthermore, the number of subjects who were able to achieve full active elbow extension 48h after eccentric exercise was greater in the DHA group (71% vs. 15%, p = 0.006, indicating significantly less muscle stiffness. No between-group differences were observed for passive elbow extension (p = 0.78 or arm swelling (p = 0.75. Skin temperature and salivary CRP concentrations did not change from baseline to 48h after exercise in either group. These findings indicate that short-term DHA supplementation reduces exercise-induced muscle soreness and stiffness. Therefore, in addition to other health benefits that n-3 fatty acids have been associated with, DHA supplementation could be beneficial for improving tolerance to new and/or strenuous exercise programs and thereby

    Full Text Available ObjectiveTo investigate the changes in the serum markers of iron metabolism and their clinical significance in patients with nonalcoholic fatty liver disease (NAFLD. MethodsA total of 68 NAFLD patients who were admitted to The Eighth People′s Hospital of Shanghai from July 2014 to April 2016 were enrolled as NAFLD group, and 70 healthy persons who underwent physical examination were enrolled as healthy control group. Among the 68 patients in the NAFLD group, 24 had NAFLD alone and 44 were complicated by abnormal alanine aminotransferase (ALT level. The levels of aspartate aminotransferase (AST, ALT, total cholesterol (TC, triglyceride (TG, and serum markers of iron metabolism [serum iron (SI, serum ferritin (SF, and serum hepcidin (HEPC] were measured for all patients, and the correlations between abnormal ALT level and serum markers of iron metabolism were analyzed. The independent samples t-test was used for comparison of continuous data between groups, the chi-square test was used for comparison of categorical data between groups, and the Pearson correlation coefficient was used to investigate the correlation between two variables. ResultsThe NAFLD group had significantly higher body mass index and serum levels of ALT, AST, TC, and TG than the healthy control group (t=9.8, 8.6, 8.5, 9.2, and 2.7, all P<0.05. Compared with the healthy control group, the NAFLD group had significantly higher levels of SI (21.7±7.1 μmol/L vs 187±6.9 μmol/L, t=2.3, P=0.02 and SF (340.2±257.6 μg/L vs 119.1±81.2 μg/L, t=6.7, P<0.01 and a significantly lower level of HEPC (12.2±5.3 μg/L vs 22.2±6.5 μg/L, t=9.9, P<0.01.

    Full Text Available OBJECTIVES: The aim of this study was to evaluate the diagnostic performance of serum HA and LN as serum markers for predicting significant fibrosis in CHB patients. METHODS: Serum HA and LN levels of 87 patients with chronic hepatitis B and 19 blood donors were assayed by RIA. Liver fibrosis stages were determined according to the Metavir scoring-system. The diagnostic performances of all indexes were evaluated by the receiver operating characteristic (ROC curves. RESULTS: Serum HA and LN concentrations increased significantly with the stage of hepatic fibrosis, which showed positive correlation with the stages of liver fibrosis (HA: r = 0.875, p < 0.001; LN: r = 0.610, p < 0.001. There were significant differences of serum HA and LN levels between F2-4 group in comparison with those in F0-F1 group (p < 0.001 and controls (p < 0.001, respectively. From ROC curves, 185.3 ng/mL as the optimal cut-off value of serum HA for diagnosis of significant fibrosis, giving its sensitivity, specificity, PPV, NPV, LR+, LR- and AC of 84.2%, 83.3%, 90.6%, 73.5%, 5.04, 0.19 and 83.9, respectively. While 132.7 ng/mL was the optimal cut-off value of serum LN, the sensitivity, specificity, PPV, NPV, LR+, LR- and AC were 71.9%, 80.0%, 87.2%, 60.0%, 3.59%, 0.35% and 74.7, respectively. Combinations of HA and LN by serial tests showed a perfect specificity and PPV of 100%, at the same time sensitivity declined to 63.2% and LR+ increased to 18.9, while parallel tests revealed a good sensitivity of 94.7%, NPV to 86.4%, and LR- declined to 0.08. CONCLUSIONS: Serum HA and LN concentrations showed positive correlation with the stages of liver fibrosis. Detection of serum HA and LN in predicting significant fibrosis showed good diagnostic performance, which would be further optimized by combination of the two indices. HA and LN would be clinically useful serum markers for predicting significant fibrosis in patients with chronic hepatitis B, when liver biopsy is

    Full Text Available Endoplasmic reticulum (ER stress and inflammation can induce hyperglycemia. Long-chain bases (LCBs from sea cucumber exhibit antihyperglycemic activities. However, their effects on ER stress and inflammation are unknown. We investigated the effects of LCBs on ER stress and inflammatory response in high-fat, fructose diet-induced obesity mice. Reactive oxygen species and free fatty acids were measured. Inflammatory cytokines in serum and their mRNA expressions in epididymal adipose tissues were investigated. Hepatic ER stress-related key genes were detected. c-Jun NH2-terminal kinase and nuclear factor κB inflammatory pathways were also evaluated in the liver. Results showed that LCBs reduced serum and hepatic reactive oxygen species and free fatty acids concentrations. LCBs decreased serum proinflammatory cytokines levels, namely interleukin (IL-1β, tumor necrosis factor-α, IL-6, macrophage inflammatory protein 1, and c-reactive protein, and increased anti-inflammatory cytokine IL-10 concentration. The mRNA and protein expressions of these cytokines in epididymal adipose tissues were regulated by LCBs as similar to their circulatory contents. LCBs inhibited phosphorylated c-Jun NH2-terminal kinase and inhibitor κ kinase β, and nuclear factor κB nuclear translocation. LCBs also inhibited mRNA expression of ER stress markers glucose regulated protein, activating transcription factor 6, double-stranded RNA-activated protein kinase-like endoplasmic reticulum kinase, and X-box binding protein 1, and phosphorylation of eukaryotic initiation factor-α and inositol requiring enzyme 1α. These results indicate that LCBs can alleviate ER stress and inflammatory response. Nutritional supplementation with LCBs may offer an adjunctive therapy for RE stress-associated inflammation.

    To investigate the prognostic value of tumor markers, cancer antigen 15-3 (CA 15-3) and carcinoembryonic antigen (CEA) levels at diagnosis of systemic recurrence. After primary treatments of locoregional breast cancers, serum CA 15-3 and/or CEA concentrations were regularly measured, and systemic recurrences were identified in 351 patients between January 1999 and December 2009. The association between tumor marker levels at systemic recurrence and survival were investigated by univariate and multivariate analyses. Elevated CA 15-3 and CEA levels were identified in 194 of 349 (55.6 %) and 111 of 308 (36.0 %) patients, respectively, at diagnosis of systemic recurrence. Elevated levels of CA 15-3 and CEA were correlated with visceral or multiple recurrences and elevated preoperative levels. Elevation of CA 15-3 was more prominent in younger patients and in primary node-positive tumors, while CEA was elevated in older patients at diagnosis and in estrogen receptor (ER)-positive tumors. Elevated tumor markers as well as ER negativity, short disease-free interval, and advanced stage at initial diagnosis showed independent prognostic significance on multivariate analysis. Among 306 patients for whom levels of both tumor markers at recurrence were available, 106 patients without elevation of either marker showed significantly better overall survival than those with elevated levels of either one or both markers, and the significance persisted in multivariate analysis. Elevated serum CA 15-3 and CEA levels at recurrence suggest increased tumor burden and may be prognostic for survival for metastatic breast cancer patients.

    Full Text Available Objective: To investigate the effects of oxaliplatin, leucovorin and fluorouracil on serum tumor markers, VEGF, CRP and matrix metalloproteinases in patients with advanced esophageal cancer. Methods: From March 2012 to March 2017 a total of 248 patients with advanced esophageal cancer were selected as the study subjects. According to random data table, they were divided into control group (n=123 and observation group (n=125 according to random data table. The control group was treated with cisplatin combined with fluorouracil, leucovorin chemotherapy, and patients in the observation group received oxaliplatin, leucovorin and fluorouracil chemotherapy, all patients were treated for 2 cycles. The changes of serum tumor markers, VEGF, CRP and matrix metalloproteinase levels in the two groups before and after treatment was compared. Results: Before treatment, there was no significant difference of the levels of serum CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 between the control group and the observation group. Compared with the group before treatment, the levels of CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 in the two groups were significantly lower. After treatment, the level of CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 in the observation group was significantly lower than those of the control group. Conclusion: Oxaliplatin, leucovorin and fluorouracil chemotherapy can effectively reduce the levels of serum tumor markers, VEGF, CRP and matrix metalloproteinase in patients with advanced esophageal cancer, it has important clinical value.

    Fractalkine has recently been introduced as an adipokine that improves glucose tolerance. Regulation of fractalkine in gestational diabetes, as well as its association with markers of obesity, glucose and lipid metabolism, inflammation and renal function, has not been elucidated. Circulating fractalkine was quantified by enzyme-linked immunosorbent assay in 74 women with gestational diabetes and 74 healthy, pregnant control subjects matched for age, BMI, and gestational age. Median (interquartile range) levels of fractalkine were not significantly different between the two groups [gestational diabetes: 2.24 (2.16) μg/l; control: 2.45 (1.38) μg/l] (P = 0.461). In multivariate linear regression analysis, fractalkine remained independently associated with homeostasis model assessment of insulin resistance (β = -0.253, P = 0.002) and the proinflammatory adipokine progranulin (β = 0.218, P = 0.007). Circulating fractalkine is not different between women with gestational diabetes and control subjects, but the adipokine is independently associated with markers of insulin resistance and proinflammatory progranulin in pregnancy. © 2014 The Authors.

    Studies suggest that inflammation impairs reverse cholesterol transport (RCT). We investigated whether serum amyloid A (SAA) contributes to this impairment using an established macrophage-to-feces RCT model. Wild-type (WT) mice and mice deficient in SAA1.1 and SAA2.1 (SAAKO) were injected intraperitoneally with (3)H-cholesterol-labeled J774 macrophages 4 hr after administration of LPS or buffered saline. (3)H-cholesterol in plasma 4 hr after macrophage injection was significantly reduced in both WT and SAAKO mice injected with LPS, but this was not associated with a reduced capacity of serum from LPS-injected mice to promote macrophage cholesterol efflux in vitro. Hepatic accumulation of (3)H-cholesterol was unaltered in either WT or SAAKO mice by LPS treatment. Radioactivity present in bile and feces of LPS-injected WT mice 24 hr after macrophage injection was reduced by 36% (P < 0.05) and 80% (P < 0.001), respectively. In contrast, in SAAKO mice, LPS did not significantly reduce macrophage-derived (3)H-cholesterol in bile, and fecal excretion was reduced by only 45% (P < 0.05). Injection of cholesterol-loaded allogeneic J774 cells, but not syngeneic bone-marrow-derived macrophages, transiently induced SAA in C57BL/6 mice. Our study confirms reports that acute inflammation impairs steps in the RCT pathway and establishes that SAA plays only a minor role in this impairment.

    To study the cause for slow recovery in male hyperthyroidism patients after treated with ATD, the changes of serum β 2 -MG, TGAb and TMAb were measured by RIA. A total of 164 male hyperthyoidism patients were divided into 3 groups by their different therapeutic effects: untreated patients (group B, n=65), treated but unrelieved patients (group C, n=52), treated and recovered patients (group D, n=47) and 58 normal persons serving as controls (group A). The results indicated that the levels of serum β 2 -MG, FT 3 and FT 4 were significantly higher in group B and C than those in group A (P 3 or FT 4 and β 2 -MG respectively in group B and C. There was no significant difference in β 2 -MG, FT 3 and FT 4 between group D and A (P>0.05). And there was no difference in the positive rates of TGAb and TMAb between group D and C(P>0.05). The serum β 2 -MG was still higher in 19.1% patients and the positive rates of TGAb and TMAb were also higher in 23.4% patients. These results suggest that β 2 -MG, TGAb and TMAb could act as serum markers of immunological remission for male hyperthyroidism patients and the determination of β 2 -MG, TGAb and TMAb could be benifical to monitoring therapeutic effect. The cause for slow recovery in about 20% male hyperthyroidism patients might be due to higher serum β 2 -MG and higher positive rates of TGAb and TMAb. (authors)

    Full Text Available Objective. To determine the significance of high serum ferritin observed in Indigenous Australian patients on maintenance haemodialysis in the Northern Territory, we assessed the relationship between ferritin and transferrin saturation (TSAT as measures of iron status and ferritin and C-reactive protein (CRP as markers of inflammation. Methods. We performed a retrospective cohort analysis of data from adult patients (≥18 years on maintenance haemodialysis (>3 months from 2004 to 2011. Results. There were 1568 patients. The mean age was 53.9 (11.9 years. 1244 (79.3% were Indigenous. 44.2% (n=693 were male. Indigenous patients were younger (mean age [52.3 (11.1 versus 57.4 (15.2, p<0.001] and had higher CRP [14.7 mg/l (7–35 versus 5.9 mg/l (1.9–17.5, p<0.001], higher median serum ferritin [1069 µg/l (668–1522 versus 794.9 µg/l (558.5–1252.0, p<0.001], but similar transferrin saturation [26% (19–37 versus 28% (20–38, p=0.516]. We observed a small positive correlation between ferritin and TSAT (r2=0.11, p<0.001, no correlation between ferritin and CRP (r2 = 0.001, p<0.001, and positive association between high serum ferritin and TSAT (p<0.001, Indigenous ethnicity (p<0.001, urea reduction ratio (p=0.001, and gender (p<0.001 after adjustment in mixed regression analysis. Conclusion. Serum ferritin and TSAT may inadequately reflect iron status in this population. The high ferritin was poorly explained by inflammation.

    Full Text Available Background and Aim: Thymol and carvacrol are two important components of thyme that have multiple medicinal uses. This study investigates the in vivo effects of these natural products on adjuvant-induced inflammation and secretion of interleukin (IL-17 and key inflammatory cytokines in rats. Materials and Methods: We injected complete Freund’s adjuvant (CFA into the hind paws of rats in order to induce inflammation. Each of the CFA-treated rat groups received gavages of thymol, carvacrol, or vehicle (CFA-only group. Rats’ paws and ankle edema were measured and then we were able to determine an inflammatory score based on the results. After 72 h of inflammation induction, sera were collected and subsequently inflamed tissue extracts were prepared for cytokine assay by ELISA. Results: Both components significantly decreased paw edema in rats (p<0.01. Thymol decreased ankle edema to 61.6% of edema in CFA-only rats (p<0.001. We observed a decreased inflammatory score in the thymol and carvacrol-treated rats. The evaluation of the tissue and serum inflammatory cytokine levels showed that both components decreased tumor necrosis factor (TNF-α levels (p<0.05. Thymol and carvacrol reduced interleukin (IL-1β serum and tissue levels, respectively. These components reduced tissue levels of IL-17 from 148.4±13.4pg/ml in CFA-only rats to 90.1±18.9pg/ml (thymol and 82.3±9.2pg/ml (carvacrol. Both components decreased serum IL-17 levels in rats (p<0.05. In comparison, the anti-inflammatory drug, indomethacin, reduced the inflammatory score and decreased tissue TNF-α and IL-1β levels but did not affect IL-17 production. Conclusion: Carvacrol and thymol could relieve inflammation symptoms possibly by downregulating serum and tissue IL-17 expression in addition to key pro-inflammatory cytokines, TNFα and IL-1β.

    Acute pancreatitis (AP) is characterized by severe inflammation and acinar cell death. Transmembrane protein 173 (TMEM173 or STING) is a DNA sensor adaptor protein on immune cells that recognizes cytosolic nucleic acids and transmits signals that activate production of interferons and the innate immune response. We investigated whether leukocyte STING signaling mediates inflammation in mice with AP. We induced AP in C57BL/6J mice (control) and C57BL/6J-Tmem173gt/J mice (STING-knockout mice) by injection of cerulein or placement on choline-deficient DL-ethionine supplemented diet. In some mice, STING signaling was induced by administration of a pharmacologic agonist. AP was also induced in C57BL/6J mice with bone marrow transplants from control or STING-knockout mice and in mice with disruption of the cyclic GMP-AMP synthase (Cgas) gene. Pancreata were collected, analyzed by histology, and acini were isolated and analyzed by flow cytometry, quantitative polymerase chain reaction, immunoblots, and enzyme-linked immunosorbent assay. Bone-marrow-derived macrophages were collected from mice and tested for their ability to detect DNA from dying acinar cells in the presence and absence of deoxyribonuclease (DNaseI). STING signaling was activated in pancreata from mice with AP but not mice without AP. STING-knockout mice developed less severe AP (less edema, inflammation, and markers of pancreatic injury) than control mice, whereas mice given a STING agonist developed more severe AP than controls. In immune cells collected from pancreata, STING was expressed predominantly in macrophages. Levels of cGAS were increased in mice with vs without AP, and cGAS-knockout mice had decreased edema, inflammation, and other markers of pancreatic injury upon induction of AP than control mice. Wild-type mice given bone marrow transplants from STING-knockout mice had less pancreatic injury and lower serum levels of lipase and pancreatic trypsin activity following induction of AP than

    To investigate impairment and clinical significance of exocrine and endocrine pancreatic function in patients after acute pancreatitis (AP). Patients with AP were invited to participate in the study. Severity of AP was determined by the Atlanta classification and definitions revised in 2012. Pancreatic exocrine insufficiency (PEI) was diagnosed by the concentration of fecal elastase-1. An additional work-up, including laboratory testing of serum nutritional markers for determination of malnutrition, was offered to all patients with low levels of fecal elastase-1 FE. Hemoglobin A1c or oral glucose tolerance tests were also performed in patients without prior diabetes mellitus, and type 3c diabetes mellitus (T3cDM) was diagnosed according to American Diabetes Association criteria. One hundred patients were included in the study: 75% (75/100) of patients had one attack of AP and 25% (25/100) had two or more attacks. The most common etiology was alcohol. Mild, moderately severe and severe AP were present in 67, 15 and 18% of patients, respectively. The mean time from attack of AP to inclusion in the study was 2.7 years. PEI was diagnosed in 21% (21/100) of patients and T3cDM in 14% (14/100) of patients. In all patients with PEI, at least one serologic nutritional marker was below the lower limit of normal. T3cDM was more frequently present in patients with severe AP (P = 0.031), but was also present in some patients with mild and moderately severe AP. PEI was present in all degrees of severity of AP. There were no statistically significantly differences according to gender, etiology and number of AP attacks. As exocrine and endocrine pancreatic insufficiency can develop after AP, routine follow-up of patients is necessary, for which serum nutritional panel measurements can be useful.

    Full Text Available It has been established that features of modern diet might be considered as a possible source of inflammatory diseases of gastrointestinal tract. Particular attention is paid to the role of different food additives in the development of intestinal inflammation, including the food additive E407, known as carrageenan. A model of chronic carrageenan-induced gastroenterocolitis of moderate severity has been elaborated, which allows us to study carrageenan-induced intestinal inflammation. In particular, the features of blood serum protein spectrum and cytokine spectrum in chronic carrageenan-induced intestinal inflammation are not studied. The female Wistar rats have been used for the experiment. Chronic carrageenan-induced gastroenterocolitis has been reproduced by the free access of animals to 1% solution of carrageenan in drinking water. Laboratory animals have been divided into 3 groups. Group № 1 consisted of experimental animals, who consumed food additive carrageenan during 2 weeks and group № 2 included experimental animals, who consumed food additive carrageenan during 4 weeks. Group № 3 consisted of intact healthy animals. The development of gastroenterocolitis has been proved morphologically and biochemically. Manipulations with animals have been carried out in accordance with the provisions of the European Convention for the Protection of Vertebrate Animals used for Experimental and other Scientific Purposes (Strasbourg, 1986. It has been established that the disease has been associated with dysproteinemia. The level of α1-globulins increased after 2 weeks of carrageenan consumption and has been normalized in animals, who consumed carrageenan during 4 weeks. The similar changes have been observed for α2-globulins level. It could be explained by production of acute phase proteins, such as α1-acid glycoprotein, C-reactive protein, fibrinogen, α2-macroglobulin, ceruloplasmin, etc. The intake of carrageenan also caused

    Full Text Available Background: Depression may result in unfavorable health outcomes as it has been associated with cardiovascular morbidity. Recent researches have suggested the role of inflammation in the pathophysiology of depression and co-morbidities associated with it although the underlying mechanism relating the two is still unclear. Aim: The present study aimed to explore the association between depression and inflammatory markers including interleukin-6 (IL-6, tumor necrosis factor-alpha (TNF-α and high sensitive c-reactive protein (hsCRP. Materials and Methods: Thirty drug-naοve patients of depression diagnosed on the basis of ICD-10 criteria, in the age group of 20-45 years were included in the study. They were compared with 30 age, gender, body mass index, socio-economic and educational status matched apparently healthy controls. The blood samples were taken after an overnight fast and serum samples were immediately stored until the time of analysis. Results: The serum levels of hsCRP were significantly higher (P = 0.042 in depression group as compared to the control group. Although the mean serum levels of IL-6 and TNF-α were higher in patients of depression, they were not statistically significant (IL-6: P = 0.055, TNF-α: P = 0.053. Conclusion: It can be inferred from our study that depression is associated with underlying low-grade inflammation, which might contribute to increased morbidity in patients of depression.

    2010-07-01

    Acute phase proteins (APPs) have been used as biomarkers of inflammation, infection and trauma for decades in human medicine but have been relatively under-utilised in the context of veterinary medicine. However, significant progress has been made in the detection, measurement and application of APPs as biomarkers in both companion and farm animal medicine over recent years. In the dog, C-reactive protein, haptoglobin and serum amyloid A have been identified as significant diagnostic 'markers' of steroid-responsive meningitis-arteritis, while in cats and cattle haptoglobin and alpha(1) acid glycoprotein and haptoglobin and serum amyloid A have proved valuable biomarkers of disease, respectively. In dairy cattle, haptoglobin and a mammary-associated serum amyloid A3 isoform, produced by the inflamed mammary gland during episodes of mastitis, have great potential as biomarkers of this economically important disease. Understanding the use of APP as biomarkers of inflammatory conditions of domestic animals has expanded significantly over recent years, and, with the insights provided by ongoing research, it is likely that these compounds will be increasingly used in the future in the diagnosis and prognosis of both companion and farm animal disease.

    Uric acid is a risk factor for coronary artery disease (CAD) in postmenopausal women but the association with inflammation and coronary microvascular endothelial dysfunction (CED) is not well-defined. The aim of this study was to determine the relationship of serum uric acid (SUA), inflammatory markers and CED. In this prospective cohort study, serum uric acid, hsCRP levels, and neutrophil count were measured in 229 postmenopausal women who underwent diagnostic catheterization, were found to have no obstructive CAD and underwent coronary microvascular function testing, to measure coronary blood flow (CBF) response to intracoronary acetylcholine. The average age was 58 years (IQR 52, 66) years. Hypertension was present in 48%, type 2 diabetes mellitus in 5.6%, and hyperlipidemia in 61.8%. CED was diagnosed in 59% of postmenopausal women. Mean uric acid level was 4.7 ± 1.3 mg/dL. Postmenopausal women with CED had significantly higher SUA compared to patients without CED (4.9 ± 1.3 vs. 4.4 ± 1.3 mg/dL; p=0.02). There was a significant correlation between SUA and % change in CBF to acetylcholine (p=0.009), and this correlation persisted in multivariable analysis. SUA levels were significantly associated with increased neutrophil count (p=0.02) and hsCRP levels (p=0.006) among patients with CED, but not those without CED. Serum uric acid is associated with coronary microvascular endothelial dysfunction in postmenopausal women and may be related to inflammation. These findings link serum uric acid levels to early coronary atherosclerosis in postmenopausal women. PMID:27993955

    Full Text Available BACKGROUND: The mechanism by which high-voltage electrical stimulation (HVPC acts on edema reduction is unknown. OBJECTIVE: To assess the effect of HVPC with negative polarity (- applied to the ankle of rats with acute joint inflammation. METHOD: Sixty-four rats were divided into four groups (n=16: inflamed+HVPC(-, 0.03 mL application of ι-carrageenan (3% to the tibiotarsal joint plus HVPC(-; inflamed+HVPC placebo, carrageenan application and HVPC placebo; normal+HVPC(-, HVPC application(-; and normal control, no intervention. The HVPC(- 100 Hz at a submotor level was applied daily for 45 min on three consecutive days. The variables were pain, hind-foot volume, and serum histamine and albumin assessed before and during the 48 hours following inflammation. The variables were compared using the t test, one-way ANOVA, nested ANOVA for repeated measures, and the post hoc Bonferroni test. Analysis of covariance was applied to adjust the effects of HVPC(- by measurements of pain, inflammation, albumin, and histamine at 24 h, and the final weight was compared to the other groups. The significance level was set at p0.05. Albumin was reduced in the groups that received the intervention, but there was no differences between them. There was only a 24 hour increase in histamine with the normal+HVPC(- (p=0.0001 and inflamed+HVPC placebo groups (p=0.01 compared to the normal control group. CONCLUSIONS: The results of the present study suggest that HVPC(- with the parameters employed did not reduce pain or edema and did not change serum albumin or histamine levels,, which indicates the inability of this resource to have a positive effect when treating treat acute joint inflammation.

    In recent years links among vitamin D deficiency, inflammation and cardio-metabolic disease were proposed. As information regarding the associations between vitamin D and inflammatory markers in the general population is sparse, we investigated the associations of 25-hydroxy vitamin D [25(OH)D] with high-sensitivity C-reactive protein (hs-CRP), fibrinogen and white blood cell count (WBC). The study population comprised 2723 men and women aged 25-88 years from the first follow-up of the Study of Health in Pomerania. Analyses of variance, linear and logistic regressions were performed to assess the associations between 25(OH)D and the three inflammatory markers. The models were adjusted for age, sex, waist circumference, diabetes mellitus, dyslipidemia, anti-inflammatory medication and month of blood sampling. The association between 25(OH)D and WBC was assessed separately in smokers (n = 718) and non-smokers (n = 2005) as effect modification was observed. We detected a U-shaped association between 25(OH)D and hs-CRP with a nadir of 21-25 ng/ml in fully-adjusted linear regression models with restricted cubic splines (p < 0.01; p' < 0.01). We further detected an inverse association between 25(OH)D and fibrinogen (p < 0.01). In addition, there was an inverse association between 25(OH)D and WBC in smokers (p = 0.02) but no association in non-smokers (p = 0.73). Our study confirms a potential role of 25(OH)D in chronic inflammation. Yet, different inflammatory biomarkers are differently associated with 25(OH)D. Beneficial effects of increasing 25(OH)D were observed for fibrinogen and WBC (in smokers only). In contrast, the U-shaped association between 25(OH)D and hs-CRP indicates that ever-increasing 25(OH)D concentrations may also be related to proinflammatory states. Copyright © 2014 Elsevier Inc.

    Full Text Available Objective: To analyze the effect of S-1 chemotherapy and FP chemotherapy on prognosis, imaging characteristics and serum marker levels after operation for gastric carcinoma. Methods: A total of 68 patients with gastric cancer who underwent radical surgery were included in the study and divided into observation group and control group patients (n=34 according to random number table. Control group received FP chemotherapy, observation group received S-1 chemotherapy, and then differences in serum tumor markers, illnessrelated factors, nutrition indexes and T cell immune function values were compared between two groups. Results: After observation group received systematic chemotherapy, serum tumor markers such as MMP-9, MMP-2, MG7-Ag, TSGF, CA72-4, CA19-9, TP and DpD as well as illness-related factors such as DKK1, MK, Leptin, Exosome and OPN were all lower than those of control group (P<0.05; nutrition and cellular immune function indexes such as TP, ALB, PA, CD4+ T and CD4+ T/ CD8+ T values were higher than those of control group and CD8+ T value was lower than that of control group (P<0.05. Conclusions: S-1 chemotherapy after operation for gastric carcinoma can inhibit the tumor activity and optimize patients’ overall condition, and it has positive clinical significance.

    Full Text Available Abstract Background Epidemiologic evidence supports a role of soy foods in breast cancer etiology. Because chronic inflammation appears to be a critical component in carcinogenesis, we examined the potential anti-inflammatory effects of soy foods. Methods The original 2-year dietary intervention randomized 220 premenopausal women of whom 183 women (90 in the intervention group and 93 in the control group were included in the current investigation; 40% were of Asian ancestry. The intervention group consumed two daily soy servings containing 50 mg of isoflavones (aglycone equivalents, whereas the controls maintained their regular diet. Five serum samples obtained at month 0, 3, 6, 12, and 24 were analyzed for interleukin (IL-6, C-reactive protein (CRP, leptin, and adiponectin by ELISA. For statistical analysis, mixed models were applied to incorporate the repeated measurements. Results: The levels of all analytes were lower in Asian than Caucasian women. Overweight women had significantly higher levels of CRP, IL-6, and leptin and lower levels of adiponectin than normal weight women. We did not observe a significant effect of soy foods on the four markers, but leptin increased in the control and not in the intervention group (p = 0.20 for group-time effect; this difference was significant for Asian (p = 0.01 and obese women (p = 0.005. Conclusion During this 2-year intervention, soy foods did not modify serum levels of CRP, IL-6, leptin, and adiponectin in premenopausal women although leptin levels remained stable among women in the intervention group who were obese or of Asian ancestry. Further studies with diverse markers of inflammation are necessary to clarify the specific effect of soy on immune responses.

    Full Text Available Objective. The primary aim of the study was to assess levels of oxidative stress markers, soluble CD40 ligand (sCD40L, serum pregnancy-associated plasma protein-A (PAPP-A, and placental growth factor (PlGF as well as carotid intima-media thickness (IMT in patients with ankylosing spondylitis (AS with active phase without concomitant classical cardiovascular risk factors. Material and methods. The observational study involved 96 male subjects: 48 AS patients and 48 healthy ones, who did not differ significantly regarding age, BMI, comorbid disorders, and distribution of classical cardiovascular risk factors. In both groups, we estimated levels of oxidative stress markers, lipid profile, and inflammation parameters as well as sCD40L, serum PAPP-A, and PlGF. In addition, we estimated carotid IMT in each subject. Results. The study showed that markers of oxidative stress, lipid profile, and inflammation, as well as sCD40L, PlGF, and IMT, were significantly higher in the AS group compared to the healthy group. Conclusion. Our results demonstrate that ankylosing spondylitis may be associated with increased risk for atherosclerosis.

    To compare the bone scintigraphy findings with a carcinoembryonic antigen (CEA) and cancer antigen 15-3 (CA 15-3) levels in breast carcinoma patients. We also investigated the relationship between anatomical bone type and its effect on tumor marker levels. The study was consisted of retrospective evaluation of 120 bone scans of patients with breast carcinoma admitted to the Nuclear Medicine Department, Medical Faculty, Hacettepe University, Ankara, Turkey between January 2003 and December 2004. The mean age of the patients was 54.7 years. We grouped the results of the bone scans into 3 as normal, equivocal and metastatic. Carcinoembryonic antigen and CA 15-3 levels were recorded from the files of the patients. Upper cut levels of 4.8 U/ml for CEA and 38 U/ml for CA 15-3 was accepted. Metastatic bone areas were distributed according to their anatomical location as long, short, flat, irregular and sesamoid and effect of bone type on tumor marker was investigated. In 16 of the patients, bone scintigraphy revealed metastases. Sixty-one patients had normal scans and in 47 patients metastases could not be ruled out. In patients with metastases, CA 15-3 was elevated in 8 and CEA was higher than the upper limit in 6. For CEA and CA 15-3, the anatomical type of bone has no any effect on serum tumor marker concentration between patients with normal and elevated levels of tumor markers in metastatic patients. Tumor markers are not solely enough in predicting bone metastases. Bone scintigraphy and tumor markers should be both used in management of patients with breast carcinoma. The anatomical type of bone has no any effect on elevation of serum tumor marker concentration. (author)

    The role played by the microenvironment in cancer induction, promotion and progression is crucial. Emerging evidence suggests that cytokines, chemokines and growth factors are major players in carcinogenesis. Therefore, a detailed understanding of factors and mechanisms associated with the processes leading from inflammation to cancer could improve the therapeutic strategies against this disease. We have used hepatocarcinoma as our model in this study. We evaluated the serum levels of 50 different cytokines, chemokines and growth factors in patients affected by HCC with chronic HCV-related hepatitis and liver cirrhosis using multiplex biometric ELISA-based immunoassay. Our data showed that some pro-inflammatory molecules were significantly up-regulated in these patients, and highlighted the complexity of the cytokine network in this disease. This work suggests the need to monitor these proteins in order to define a profile that could characterize patients with HCC or to help identify useful markers. This could lead to better definition of the disease state, and to an increased understanding of the relationships between chronic inflammation and cancer.

    Vitamin D-deficient rickets (DR) has recently re-emerged among developed countries. Vitamin D deficiency can influence biochemical results of patients with fibroblast growth factor 23 (FGF23)-related hereditary hypophosphatemic rickets (HR), making differential diagnosis difficult. In the present study we evaluated the utility of serum FGF23 levels in the diagnosis of DR and during its treatment. The study group comprised 24 children with DR and 8 children with HR. Serum FGF23 levels and bone metabolism-related measurements were assessed. Serum FGF23 levels in patients with DR were less than 19 pg/ml, while those in patients with HR were more than 57 pg/ml. There were significant differences in serum levels of calcium, phosphate, parathyroid hormone, and 1,25-dihydroxyvitamin D, as well as tubular maximum phosphate reabsorption per glomerular filtration rate between patients with DR and HR, but these values were not fully mutually exclusive. In addition, serum FGF23 and phosphate levels were increased following treatment. Serum FGF23 level is the most critical biochemical marker for distinguishing DR from HR and might be a good indicator of biochemical response to the intervention. Serum FGF23 levels show utility for the diagnosis of DR and in the assessment of its response to treatment.

    High sensitivity serum C-reactive protein (hs-CRP) has come into clinical use as a marker of risk for cardiovascular disease (CVD). In addition to a role as a marker of disease, CRP has also been implicated in the pathogenesis of CVD. Specific small-molecule inhibitors of CRP have recently been developed with the intent of mitigating cardiac damage during acute myocardial infarction. However, the use of CRP, both as a risk marker and a disease target are controversial for several reasons. Serum hs-CRP concentrations can be elevated on the basis of genetics, female gender, and non-Caucasian ethnicity. It is not clear, in these contexts, that elevations of hs-CRP have any pathological significance. As a non-specific indicator of inflammation, CRP is also not a specific indicator of a single disease state such as cardiovascular disease but elevated concentrations can be seen in association with other comorbidities including obesity and pulmonary disease. In sharp contrast to the proposed inhibition of CRP for cardiovascular disease treatment, the infusion of CRP has been shown to have profound therapeutic benefits for autoimmune disease and septic shock. The balance between the risks and benefits of these competing views of the role of CRP in disease and disease therapy is reminiscent of the ongoing controversy regarding the use of non-steroidal anti-inflammatory drugs (NSAIDs) for musculoskeletal disease and their cardiovascular side effects. Soon, NSAIDs may not be the only agents about which Rheumatologists and Cardiologists may spar.

    Intestinal production of endocannabinoid and oleoylethanolamide (OEA) is impaired in high-fat diet/obese rodents, leading to reduced satiety. Such diets also alter the intestinal microbiome in association with enhanced intestinal permeability and inflammation, however little is known of these effects in humans. This study aimed to: (i) evaluate effects of lipid on plasma anandamide (AEA), 2-arachidonyl-sn-glycerol (2-AG) and OEA in humans, and (ii) examine relationships with intestinal permeability, inflammation markers and incretin hormone secretion. 20 lean, 18 overweight and 19 obese participants underwent intraduodenal Intralipid® infusion (2 kcal/min) with collection of endoscopic duodenal biopsies and blood. Plasma AEA, 2-AG, and OEA (HPLC/tandem mass spectrometry), tumour necrosis factor-α (TNF-α), glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) (multiplex), and duodenal expression of occludin, zona-occludin-1 (ZO-1), intestinal-alkaline-phosphatase (IAP), and toll-like receptor-4 (TLR4) (RT-PCR), were assessed. Fasting plasma AEA was increased in obese, compared with lean and overweight (Plean (Plean and overweight. The relationships between plasma AEA with duodenal ZO-1 and IAP, and GIP, suggest that altered endocannabinoid signalling may contribute to changes in intestinal permeability, inflammation and incretin release in human obesity.

    Early detection and treatment is critically important for lung cancer patients. Inflammatory mediators such as IL-6, IL-10, and MCP-1 participate in lung cancer regulation. CEA, CA125, and ProGRP are commonly used serum tumor markers for lung cancer. In this study, we assessed the sensitivity and specificity of CEA, CA125, and ProGRP when used in combination with IL-6, IL-10, and MCP in lung cancer diagnosis. Serum from three different groups (healthy controls, individuals with high risk for lung cancer, and lung cancer patients) was collected. Electrochemiluminescence was used to detect expressions of CEA, CA125, and ProGRP; ELISA was used to examine serum levels of IL-6, IL-10, and MCP-1. Specificity and sensitivity of single as well as combination markers in lung cancer diagnosis were determined. Results indicated that CEA, CA125, ProGRP, and MCP-1 were significantly up-regulated in lung cancer patients as compared to those in controls and high risk individuals. Higher IL-6 and IL-10 levels were observed in both lung cancer patients and high-risk individuals as compared to those in controls. Highest sensitivity (95.2%) in cancer diagnosis was achieved when all six markers were used. This was followed by a combination of IL-6, IL-10, CEA, CA125, and ProGRP (92.6%). The most sensitive (88.6%). Four-marker combination was composed of IL-6, CEA, CA125, and ProGRP. As the combined usage of CEA, CA125, ProGRP, IL-6, IL-10, and MCP-1 significantly improved sensitivity of lung cancer detection; this biomarker arrangement may be beneficial for early diagnosis, treatment, and prognosis of lung cancer.

    BPH is a common disease associated with age and obesity. However, the biological pathways between obesity and BPH are unknown. Our objective was to investigate biomarkers of systemic and prostate tissue inflammation as potential mediators of the obesity and BPH association. Participants included 191 men without prostate cancer at prostate biopsy. Trained staff measured weight, height, waist and hip circumferences, and body composition by bioelectric impedance analysis. Systemic inflammation was estimated by serum IL-6, IL-1β, IL-8, and TNF-α; and by urinary prostaglandin E2 metabolite (PGE-M), F2-isoprostane (F2iP), and F2-isoprostane metabolite (F2iP-M) levels. Prostate tissue was scored for grade, aggressiveness, extent, and location of inflammatory regions, and also stained for CD3 and CD20 positive lymphocytes. Analyses investigated the association between multiple body composition scales, systemic inflammation, and prostate tissue inflammation against BPH outcomes, including prostate size at ultrasound and LUTS severity by the AUA-symptom index (AUA-SI). Prostate size was significantly associated with all obesity measures. For example, prostate volume was 5.5 to 9.0 mls larger comparing men in the 25th vs. 75th percentile of % body fat, fat mass (kg) or lean mass (kg). However, prostate size was not associated with proinflammatory cytokines, PGE-M, F2iP, F2iP-M, prostate tissue inflammation scores or immune cell infiltration. In contrast, the severity of prostate tissue inflammation was significantly associated with LUTS, such that there was a 7 point difference in AUA-SI between men with mild vs. severe inflammation (p = 0.004). Additionally, men with a greater waist-hip ratio (WHR) were significantly more likely to have severe prostate tissue inflammation (p = 0.02), and a high WHR was significantly associated with moderate/severe LUTS (OR = 2.56, p = 0.03) among those participants with prostate tissue inflammation. The WHR, an estimate of centralized

    Full Text Available To determine the effects of niacin on adiponectin and markers of adipose tissue inflammation in a mouse model of obesity.Male C57BL/6 mice were placed on a control or high-fat diet (HFD and were maintained on such diets for the duration of the study. After 6 weeks on the control or high fat diets, vehicle or niacin treatments were initiated and maintained for 5 weeks. Identical studies were conducted concurrently in HCA2 (-/- (niacin receptor(-/- mice.Niacin increased serum concentrations of the anti-inflammatory adipokine, adiponectin by 21% in HFD-fed wild-type mice, but had no effect on lean wild-type or lean or HFD-fed HCA2 (-/- mice. Niacin increased adiponectin gene and protein expression in the HFD-fed wild-type mice only. The increases in adiponectin serum concentrations, gene and protein expression occurred independently of changes in expression of PPARγ C/EBPα or SREBP-1c (key transcription factors known to positively regulate adiponectin gene transcription in the adipose tissue. Further, niacin had no effect on adipose tissue expression of ERp44, Ero1-Lα, or DsbA-L (key ER chaperones involved in adiponectin production and secretion. However, niacin treatment attenuated HFD-induced increases in adipose tissue gene expression of MCP-1 and IL-1β in the wild-type HFD-fed mice. Niacin also reduced the expression of the pro-inflammatory M1 macrophage marker CD11c in HFD-fed wild-type mice.Niacin treatment attenuates obesity-induced adipose tissue inflammation through increased adiponectin and anti-inflammatory cytokine expression and reduced pro-inflammatory cytokine expression in a niacin receptor-dependent manner.

    Chronic low-grade inflammation plays a pivotal role in the pathogenesis of obesity, due to its associated chronic diseases such as type II diabetes, cardiovascular diseases, pulmonary diseases and cancer. Thus, targeting inflammation is an attractive strategy to counter the burden of obesity-induced health problems. Recently, food-derived bioactive compounds have been spotlighted as a regulator against various chronic diseases due to their low toxicity, as opposed to drugs that induce severe side effects. Here we describe the beneficial effects of dietary anthocyanins on obesity-induced metabolic disorders and inflammation. Red cabbage microgreen, blueberry, blackcurrant, mulberry, cherry, black elderberry, black soybean, chokeberry and jaboticaba peel contain a variety of anthocyanins including cyanidins, delphinidins, malvidins, pelargonidins, peonidins and petunidins, and have been reported to alter both metabolic markers and inflammatory markers in cells, animals, and humans. This review discusses the interplay between inflammation and obesity, and their subsequent regulation via the use of dietary anthocyanins, suggesting an alternative dietary strategy to ameliorate obesity and obesity associated chronic diseases.

    An association between periodontitis and nonalcoholic fatty liver disease (NAFLD) has been reported by experimental animal and epidemiologic studies. This study investigated whether circulating levels of serum C-reactive protein (CRP) and a weighted genetic CRP score representing markers of inflammatory burden modify the association between periodontitis and NAFLD. Data came from 2,481 participants of the Study of Health in Pomerania who attended baseline examination that occurred between 1997 and 2001. Periodontitis was defined as the percentage of sites (0%, 3 mg/L. Periodontitis was positively associated with higher prevalence odds of NAFLD, and this relationship was modified by serum CRP levels.

    Objective Schizophrenia is associated with atopy and increased inflammatory markers. We report a population-based longitudinal study of the associations between childhood atopic disorders, subsequent serum inflammatory markers, interleukin 6 (IL-6) and C-reactive protein (CRP), and the risk of psychotic experiences (PEs). Method PEs were assessed at age 13 years (n = 6785). Presence of clinician-diagnosed atopic disorders (asthma and eczema) was determined from parent-completed questionnaires at age 10 years (n = 7814). Serum IL-6 and CRP were measured at age 9 years (n = 5076). Logistic regression examined the association between (1) atopy and PEs, (2) inflammatory markers and PEs, and (3) mediating effects of inflammatory markers on the atopy–PEs association. Linear regression examined the association between atopy and inflammatory markers. Age, gender, social class, ethnicity and body mass index were included as potential confounders. Results At age 10 years, about 14% of the sample was reported to have asthma, 12% eczema, and 7% both asthma and eczema. Compared with children with no atopy, risk of PEs at age 13 years was increased for all of these groups; adjusted odds ratios (95% CI) were, respectively, 1.39 (1.10–1.77), 1.33 (1.04–1.69), and 1.44 (1.06–1.94). Atopy was associated with increased serum IL-6 and CRP; however, this did not mediate association between atopy and PEs. Inflammatory markers were not associated with later PEs. Conclusion Childhood atopic disorders increase the risk of psychotic experiences in adolescence. Follow-up of these individuals will be useful to determine the effect of atopy and inflammation on different trajectories of early-life PEs. PMID:24268471

    Diabetic endothelial dysfunction was characterized by altered levels of adhesion molecules and cytokines. Aim of our study was to evaluate the effects of diabetic serum on cell-growth and proinflammatory markers in human saphenous vein endothelial cells (HSVEC) from diabetic and non-diabetic patients. Diabetic serum showed (1) complementary proliferative activity for non-diabetic and diabetic HSVEC, (2) unchanged surface expression of adhesion molecules, and (3) elevated levels of sICAM-1 in HSVEC of all donors. The concentration of sVCAM-1 was increased only in diabetic cells. The proinflammatory state of diabetic HSVEC characterized by increased levels of cytokines was compensated. We concluded that even under normoglycemic conditions the serum itself contains critical factors leading to abnormal regulation of inflammation in diabetics. We introduced an in vitro model of diabetes representing the endothelial situation at the beginning of diabetes (non-diabetic cells/diabetic serum) as well as the diabetic chronic state (diabetic cells/diabetic serum)

    Background The predictive and prognostic value of carcinoembryonic antigen (CEA), cytokeratin-19 fragments (Cyfra21-1), squamous cell carcinoma antigen (SCCA) and neuron-specific enolase (NSE) has been investigated in non-small-cell lung cancer (NSCLC) patients. However, few studies have directly focused on the association between these markers and epidermal growth factor receptor (EGFR) mutation status or mutation subtypes. Patients and methods We retrospectively analyzed 1016 patients with stage I-IIIA NSCLC who underwent complete resection between 2008 and 2012. Correlations between serum tumor marker levels and EGFR mutations and survival parameters were analyzed and prognostic factors were identified. Results Cyfra21-1 levels (P = 0.032 for disease-free survival [DFS]; P CEA levels (P CEA (P = 0.005) and clinical stage were predictive factors of DFS, while elevated CEA (P = 0.005) and Cyfra21-1 (P = 0.027) were independent prognostic factors. Conclusion Cyfra21-1 and CEA exhibit different predictive and prognostic values between EGFR-mutated and wild-type adenocarcinomas, as well as between EGFR mutation subtypes. The prognostic impact of preoperative serum tumor markers should be evaluated together with EGFR mutation status. PMID:27072585

    Arabinoxylan (AX), a non-starch polysaccharide extracted from cereals such as wheat, rice and millets, is known to impart various health promoting effects. Our earlier study suggested that finger millet (FM) could ameliorate high fat diet (HFD)-induced metabolic derangements. The present study is aimed to evaluate the effect of FM-AX supplementation, a key bioactive from finger millet, on HFD-induced metabolic and gut bacterial derangements. Male Swiss albino mice were fed with normal chow diet (NPD) or HFD (60%kcal from fat) for 10 weeks. FM-AX was orally supplemented at doses of 0.5 and 1.0g/kg bodyweight on every alternate day for 10 weeks. Glucose tolerance, serum hormones, hepatic lipid accumulation and inflammation, white adipose tissue marker gene expression, adipocyte size and inflammation; metagenomic alterations in cecal bacteria; cecal short chain fatty acids and colonic tight junction gene expressions were studied. FM-AX supplementation prevented HFD-induced weight gain, alerted glucose tolerance and serum lipid profile, hepatic lipid accumulation and inflammation. Hepatic and white adipose tissue gene expressions were beneficially modulated. Further, AX supplementation prevented metagenomic alterations in cecum; improved ileal and colonic health and overall prevented metabolic endotoxemia. Present work suggests that AX from finger millet can be developed as a nutraceutical for the management of HFD- induced obesity. Copyright © 2017 Elsevier B.V. All rights reserved.

    To examine the relationship between polycystic ovary syndrome (PCOS), cardiovascular risk factors, cardiovascular disease (CVD), and chronic inflammation and analyze data regarding pharmacologic therapies that are recommended to reduce CVD risk in PCOS and the impact of those therapies on chronic inflammation. A search of MEDLINE (1950-October 2011) was conducted to identify clinical studies pertaining to the identification and treatment of CVD and chronic low-grade inflammation in PCOS. Search terms included polycystic ovary syndrome, cardiovascular disease, inflammation, metformin, thiazolidinedione, and statin. Bibliographies of these studies and review articles were also examined. English-language clinical studies evaluating the effect of metformin, thiazolidinediones, and statins on inflammatory markers, endothelial function, adhesion molecules, fibrinolysis, cytokines, and adipokines in PCOS were included. Women with PCOS have an increased prevalence of many cardiovascular risk factors including obesity, android fat distribution, insulin resistance, impaired glucose tolerance, diabetes, dyslipidemia, hypertension, and metabolic syndrome. Markers of chronic low-grade inflammation, which are associated with an increased risk of CVD, are also elevated in PCOS. Clinical guidelines recommend the use of insulin sensitizers and statins to prevent CVD in some patients with PCOS. Current literature indicates that each of these medication classes has beneficial effects on inflammation, as well. Although there are currently no studies to determine whether these treatments decrease CVD in PCOS, it can be hypothesized that drugs impacting chronic inflammation may reduce cardiovascular risk. Some studies show that metformin, thiazolidinediones, and statins have beneficial effects on inflammatory markers in PCOS; however, the data are inconsistent. There is insufficient information to recommend any pharmacologic therapies for their antiinflammatory effects in PCOS in the

    Accelerated bone loss significantly increases the risk of osteoporosis and fracture. The mechanisms underlying bone loss remain incompletely understood, and there are few available biomarkers. We utilized a novel proteomics approach to identify serum peptides and proteins associated with bone loss in 1967 older men who were randomly chosen from the Osteoporotic Fracture in Men Study (MrOS study) (age ≥ 65 yrs). Men had 2-3 measures of femoral neck BMD over an average follow-up of 4.6 years. Change in BMD was estimated and then categorized into three groups: maintained BMD (n=453), expected loss (n=1185) and accelerated loss (n=237). A liquid chromatography–ion mobility separation-mass spectrometry (LC-IMS-MS) proteomics platform was used to identify and quantify peptides from serum proteins. The whole cohort was randomly divided into discovery (N= 960) and validation (N= 915) sub-cohorts. Linear regression models and a random forest approach were used to discover differentially abundant individual peptides and a proteomic signature that distinguished individuals with accelerated bone loss from those who maintained BMD. Network analyses were performed using the MetaCore knowledgebase. We identified 12 peptides that were associated with BMD loss in both discovery (P< 0.1 FDR) and replication sub-cohorts (P<0.05). Those 12 peptides mapped to the following proteins: ALS, LYVE1, RNAS1, C2, ICOSL, C163A, C7, HEMO, CD14, CERU, CRAC1 and CD59. Meta-analysis of peptidesassociated with bone loss identified 6 additional proteins including GRP78, IGF-2, SHBG, ENPP2, IBP2 and IBP6. We also identified a proteomic signature that was predictive of BMD loss with a discriminative value similar to serum bone marker carboxy-terminal collagen crosslink peptide (CTX). Interestingly, combining the proteomic signature with CTX significantly improved the ability to discriminate men with accelerated loss. In summary, we have identified potential new biomarkers for bone loss that provide

    Uric acid acts as both a pathogenic inflammatory mediator and an antioxidative agent. Several studies have shown that uric acid level correlates with the incidence, severity, and prognosis of pulmonary diseases. However, the association between uric acid level and acute respiratory distress syndrome (ARDS) has not been studied. This study was conducted to elucidate how serum uric acid level is related with clinical prognosis of ARDS. A retrospective cohort study with propensity score matching was conducted at a medical intensive care unit of a tertiary teaching hospital. The medical records of patients diagnosed with ARDS admitted from 2005 through 2011 were reviewed. Two hundred thirty-seven patients with ARDS met the inclusion criteria. Patients with a serum uric acid level uric acid group, and those with a level ≥3 mg/dL were classified into the normal to high uric acid group. We selected 40 patients in each group using propensity score matching. A higher percentage of patients in the low uric acid group experienced clinical improvement in ARDS. More patients died from sepsis in the normal to high uric acid group. Kaplan-Meier analysis showed that a low serum uric acid level was significantly associated with better survival rate. In patients with ARDS, a low serum uric acid level may be a prognostic marker of a low risk of in-hospital mortality.

    To reveal the correlation between benign prostatic hyperplasia (BPH) histologic inflammation and serum prostate-specific antigen (sPSA) concentrations, and the possible mechanism. Patients underwent surgery at the Urology Department of West China Hospital of Sichuan University were retrospectively studied. Preoperative sPSA and transrectal ultrasonography were measured. According to the histopathological classification system for chronic prostatic inflammation proposed by the Chronic Prostatitis Collaborative Research Network (CPCRN) and the International Prostatitis Collaborative Network (IPCN), we classified the histologic sections of prostatic biopsy into glandular, periglandular, and stromal inflammation by the anatomical location of inflammatory infiltration. The glandular inflammation was graded according to the inflammatory aggressiveness. The periglandular and stromal inflammation were graded according to the inflammatory density. The correlation between histologic inflammation and sPSA was studied by a multiple regression model in conjunction with age and total prostatic volume. A total of 454 patients with exclusively BPH were analyzed. The periglandular inflammatory infiltration was the most common pattern (95.6%). Single regression analysis revealed that total prostatic volume, the aggressiveness of glandular inflammation, and the intensity of periglandular and stromal inflammation were correlated with sPSA. However, the multiple regression analysis revealed that only the total prostatic volume and the aggressiveness of glandular inflammation were correlated significantly with sPSA (R = .389, 0.289; P = .000). The aggressiveness of glandular inflammatory infiltration in BPH is a significant contributor to elevated sPSA levels. The theory of leakage may be the most reasonable mechanism to reveal the correlation morphologically. We should take inflammation into consideration when interpreting the abnormal elevating of sPSA levels. Copyright © 2011

    We investigated weak cation magnetic separation technology and matrix-assisted laser desorption ionization-time of flight-mass spectrometry (MALDI-TOF-MS) in screening serum protein markers of primary type I osteoporosis. We selected 16 postmenopausal women with osteoporosis and nine postmenopausal women as controls to find a new method for screening biomarkers and establishing a diagnostic model for primary type I osteoporosis. Serum samples were obtained from controls and patients. Serum protein was extracted with the WCX protein chip system; protein fingerprints were examined using MALDI-TOF-MS. The preprocessed and model construction data were handled by the ProteinChip system. The diagnostic models were established using a genetic arithmetic model combined with a support vector machine (SVM). The SVM model with the highest Youden index was selected. Combinations with the highest accuracy in distinguishing different groups of data were selected as potential biomarkers. From the two groups of serum proteins, 123 cumulative MS protein peaks were selected. Significant intensity differences in the protein peaks of 16 postmenopausal women with osteoporosis were screened. The difference in Youden index between the four groups of protein peaks showed that the highest peaks had mass-to-charge ratios of 8909.047, 8690.658, 13745.48, and 15114.52. A diagnosis model was established with these four markers as the candidates, and the model specificity and sensitivity were found to be 100%. Two groups of specimens in the SVM results on the scatterplot were distinguishable. We established a diagnosis model, and provided a new serological method for screening and diagnosis of osteoporosis with high sensitivity and specificity.

    As centenarians well represent the model of healthy aging, there are many important implications in revealing the underlying molecular mechanisms behind such successful aging. By combining NMR metabonomics and shot-gun lipidomics in serum we analyzed metabolome and lipidome composition of a group of centenarians with respect to elderly individuals. Specifically, NMR metabonomics profiling of serum revealed that centenarians are characterized by a metabolic phenotype distinct from that of elderly subjects, in particular regarding amino acids and lipid species. Shot- gun lipidomics approach displays unique changes in lipids biosynthesis in centenarians, with 41 differently abundant lipid species with respect to elderly subjects. These findings reveal phospho/sphingolipids as putative markers and biological modulators of healthy aging, in humans. Considering the particular actions of these metabolites, these data are suggestive of a better counteractive antioxidant capacity and a well-developed membrane lipid remodelling process in the healthy aging phenotype.

    Bronchodilator responsiveness (BDR) and eosinophilic inflammation are characteristic features of asthma. Objective. The aim of this study was to compare the relationships of BDR after methacholine challenge or adenosine 5'-monophosphate (AMP) challenge to blood eosinophil markers in children with asthma. Methacholine and AMP challenges were performed on 69 children with mild intermittent to moderate persistent asthma. BDR was calculated as the change in forced expiratory volume in 1 second, expressed as percentage change of the value immediately after the each challenge and the value after inhalation of salbutamol. Serum total IgE levels, blood eosinophil counts, and serum eosinophil cationic protein (ECP) levels were determined for each subject. A positive relationship between serum total IgE levels and BDR was found only after the AMP challenge (R(2) = 0.345, p = .001) rather than after the methacholine challenge (R(2) = 0.007, p = .495). Peripheral blood eosinophil counts correlated more significantly with BDR after AMP challenge (R(2) = 0.212, p = .001) than BDR after methacholine challenge (R(2) = 0.002, p = .724). Both BDR after methacholine challenge (R(2) = 0.063, p = .038) and BDR after AMP challenge (R(2) = 0.192, p = .001) were significantly correlated with serum ECP levels. BDR after AMP challenge may be more closely related to eosinophilic inflammation, compared with that after methacholine challenge.

    Full Text Available Stroke is a multifactorial disease that may be associated with aberrant DNA methylation profiles. We investigated epigenetic dysregulation for the methylenetetrahydrofolate reductase (MTHFR gene among ischemic stroke patients. Cases and controls were recruited after obtaining signed written informed consents following a screening process against the inclusion/exclusion criteria. Serum vitamin profiles (folate, vitamin B12, and homocysteine were determined using immunoassays. Methylation profiles for CpGs A and B in the MTHFR gene were determined using a bisulfite-pyrosequencing method. Methylation of MTHFR significantly increased the susceptibility risk for ischemic stroke. In particular, CpG A outperformed CpG B in mediating serum folate and vitamin B12 levels to increase ischemic stroke susceptibility risks by 4.73-fold. However, both CpGs A and B were not associated with serum homocysteine levels or ischemic stroke severity. CpG A is a potential epigenetic marker in mediating serum folate and vitamin B12 to contribute to ischemic stroke.

  11. Interactions between C-Reactive Protein Genotypes with Markers of Nutritional Status in Relation to Inflammation

    Full Text Available Inflammation, as indicated by C-reactive protein concentrations (CRP, is a risk factor for chronic diseases. Both genetic and environmental factors affect susceptibility to inflammation. As dietary interventions can influence inflammatory status, we hypothesized that dietary effects could be influenced by interactions with single nucleotide polymorphisms (SNPs in the CRP gene. We determined 12 CRP SNPs, as well as various nutrition status markers in 2010 black South Africans and analyzed their effect on CRP. Interactions were observed for several genotypes with obesity in determining CRP. Lipid intake modulated the pro-inflammatory effects of some SNPs, i.e., an increase in both saturated fatty acid and monounsaturated fatty acid intake in those homozygous for the polymorphic allele at rs2808630 was associated with a larger increase in CRP. Those harboring the minor alleles at rs3093058 and rs3093062 presented with significantly higher CRP in the presence of increased triglyceride or cholesterol intake. When harboring the minor allele of these SNPs, a high omega-6 to -3 ratio was, however, found to be anti-inflammatory. Carbohydrate intake also modulated CRP SNPs, as HbA1C and fasting glucose levels interacted with some SNPs to influence the CRP. This investigation highlights the impact that nutritional status can have on reducing the inherent genetic susceptibility to a heightened systemic inflammatory state.

    Objective: To investigate the relationship between changes of blood HBV DNA viral load and serum liver fibrosis markers levels in patients with chronic hepatitis B. Methods: In 2002, 20 patients with hepatitis B were divided into two groups: Group A treated with antiviral ageat (n=10), Group B not treated.Five years later (2007) the blood viral load (with FQ-PCR) and serum levels of hepatic fibrosis markers (with RIA) were determined in these patients. Results: The average log viral load in serum in the tow groups were 3.56 ± 1.12 (treated group) and 7.76 ± 1.23 respectively with significant difference (P<0.05). In 2002, serum liver fibrosis markers (HA, LN, IV-C, PCIII) levels were about the same in the two groups were (82.72 ± 30.62μg/ml, 71.18 ± 26.71μg/ml, 93.77 ± 69.87μg/ml, 91.4 ± 18.64μg/ml and 79.32 ± 31.34μg/ml, 70.25 ± 28.23)μg/ml, 90.35 ± 67.81μg/ml, 85.77 ± 20.56μg/ml respectively). In 2007, in the treated patients, serum liver fibrosis markers HA, LN, IV-C, PCIII levels were 85.72 ± 29.52μg/ml, 70.18 ± 25.4μg/ml, 94.2 ± 70.92μg/ml, 93.4 ± 19.32μg/ml respectively However, in the non-treated groups, the serum HA, LN, IV-C, PCIII levels were105.67 ± 28.54μg/ml, 97.75 ± 26.25μg/ml, 132 ± 72.13μg/ml, 120.72 ± 19.87μg/ml, being significantly higher than those in the treated group (P<0.05). Conclusion: Effective decrease of the viral load might control the progress of hepatic fibrosis in patients with chronic hepatitis B. (authors)

    Monitoring sputum eosinophils in asthma predicts exacerbations and improves management of asthma. Thus far, blood eosinophils and FE(NO) show contradictory results in predicting eosinophilic airway inflammation. More recently, serum periostin was proposed as a novel biomarker for eosinophilic inflammation. Quantifying the mutual relationships of blood eosinophils, FE(NO), and serum periostin with sputum eosinophils by external validation in two independent cohorts across various severities of asthma. The first cohort consisted of 110 patients with mild to moderate asthma (external validation cohort). The replication cohort consisted of 37 patients with moderate to severe asthma. Both cohorts were evaluated cross-sectionally. Sputum was induced for the assessment of eosinophils. In parallel, blood eosinophil counts, serum periostin concentrations and FENO were assessed. The diagnostic accuracy of these markers to identify eosinophilic asthma (sputum eosinophils ≥3%) was calculated using receiver operating characteristics area under the curve (ROC AUC). In the external validation cohort, ROC AUC for blood eosinophils was 89% (peosinophilic from non-eosinophilic airway inflammation (ROC AUC=55%, p=0.44). When combining these three variables, no improvement was seen. The diagnostic value of blood eosinophils was confirmed in the replication cohort (ROC AUC 85%, peosinophils had the highest accuracy in the identification of sputum eosinophilia in asthma. The use of blood eosinophils can facilitate individualised treatment and management of asthma. NTR1846 and NTR2364. Published by the BMJ Publishing Group Limited.

    To compare several noninvasive indices of fibrosis in chronic viral hepatitis B, including liver shear-wave velocity (SWV), hyaluronic acid (HA), collagen type IV (CIV), procollagen type III (PCIII), and laminin (LN). Acoustic radiation force impulse (ARFI) was performed in 157 patients with chronic viral hepatitis B and in 30 healthy volunteers to measure hepatic SWV (m/s) in a prospective study. Serum markers were acquired on the morning of the same day of the ARFI evaluation. Receiver operating characteristic (ROC) analysis was performed to evaluate and compare the accuracies of SWV and serum markers using METAVIR scoring from liver biopsy as a reference standard. The most accurate test for diagnosing fibrosis F ≥ 1 was SWV with the area under the ROC curve (AUC) of 0.913, followed by LN (0.744), HA (0.701), CIV (0.690), and PCIII (0.524). The best test for diagnosing F ≥ 2 was SWV (AUC of 0.851), followed by CIV (0.671), HA (0.668), LN (0.562), and PCIII (0.550). The best test for diagnosing F ≥ 3 was SWV (0.854), followed by CIV (0.693), HA (0.675), PCIII (0.591), and LN (0.548). The best test for diagnosing F = 4 was SWV (0.965), followed by CIV (0.804), PCIII (0.752), HA (0.744), and LN (0.662). SWV combined with HA and CIV did not improve diagnostic accuracy (AUC = 0.931 for F ≥ 1, 0.863 for F ≥ 2, 0.855 for F ≥ 3, 0.960 for F = 4). The performance of SWV in diagnosing liver fibrosis is superior to that of serum markers. However, the combination of SWV, HA, and CIV does not increase the accuracy of diagnosing liver fibrosis and cirrhosis

    Psoriasin (S100A7) and koebnerisin (S100A15) are proinflammatory proteins upregulated in psoriasis, but their relation to atherosclerosis remains unclear. To evaluate the role of serum psoriasin and koebnerisin as possible markers for subclinical atherosclerosis in patients with psoriasis. Serum levels of psoriasin and koebnerisin were measured by ELISA in 45 patients with psoriasis and in 45 healthy controls (HCs). Intima-media thickness (IMT) of the right and left common carotid arteries was measured to detect the presence of subclinical atherosclerosis. Clinical severity of psoriasis was estimated using the Psoriasis Area and Severity Index (PASI). Compared with HCs, patients with psoriasis had significantly higher levels of psoriasin (26.61 ± 22.45 ng/mL vs. 6.31 ± 1.68 ng/mL, P  0.01) and serum koebnerisin (r = 0.48, P psoriasis with subclinical atherosclerosis had higher serum levels of koebnerisin compared with patients without subclinical atherosclerosis (P = 0.04), which was not observed for psoriasin (P = 0.94). Serum psoriasin and koebnerisin correlate with IMT, underlining their value as a potential link between psoriasis and atherosclerosis. In particular, koebnerisin seems to be a useful marker of subclinical atherosclerosis in patients with psoriasis. © 2018 British Association of Dermatologists.

    Serum adenosine deaminase (ADA) activity increases in diseases where cellular immunity is involved. Since cell-mediated immune responses play a paramount role in the pathogenesis and healing of the visceral leishmaniasis, therefore, the present study was undertaken to evaluate the serum ADA activity in different pathological conditions. Adenosine deaminase was determined in sera of active visceral leishmaniasis (VL) patients (n = 39), active postkala-azar dermal leishmaniasis (PKDL) cases (n = 34) at the point of diagnosis and after treatment stages along with healthy controls (n = 30), endemic healthy subjects (n = 34) and endemic asymptomatic subjects (n = 34).Our in-vitro result revealed that monocytes secrete significant ADA level in response to Leishmania donovani (L.donovani) stimulation. The serum ADA activity in active VL and PKDL subjects were found to be significantly higher than that of respective treated cases and healthy controls. We also observed a marginal number (17.6%) of endemic asymptomatic subjects showed elevated serum ADA activity. Further, the ADA activity in PKDL was found to be decreased gradually during the different phases of treatment. Interestingly, 2 out of 32 treated VL cases found to have high serum ADA activity during follow up period were relapsed within few days. These results suggest the possibility of ADA as a marker of clinical pathogenesis and can be used as a surrogate marker in the diagnosis and prognosis of VL and PKDL. PMID:27186641

    Full Text Available Critical to the design and assessment of interventions for enteropathy and its developmental consequences in children living in impoverished conditions are non-invasive biomarkers that can detect intestinal damage and predict its effects on growth and development. We therefore assessed fecal, urinary and systemic biomarkers of enteropathy and growth predictors in 375 6-26 month-old children with varying degrees of malnutrition (stunting or wasting in Northeast Brazil. 301 of these children returned for followup anthropometry after 2-6m. Biomarkers that correlated with stunting included plasma IgA anti-LPS and anti-FliC, zonulin (if >12m old, and intestinal FABP (I-FABP, suggesting prior barrier disruption; and with citrulline, tryptophan and with lower serum amyloid A (SAA (suggesting impaired defenses. In contrast, subsequent growth was predicted in those with higher fecal MPO or A1AT and also by higher L/M, plasma LPS, I-FABP and SAA (showing intestinal barrier disruption and inflammation. Better growth was predicted in girls with higher plasma citrulline and in boys with higher plasma tryptophan. Interactions were also seen with fecal MPO and neopterin in predicting subsequent growth impairment. Biomarkers clustered into markers of 1 functional intestinal barrier disruption and translocation, 2 structural intestinal barrier disruption and inflammation and 3 systemic inflammation. Principle components pathway analyses also showed that L/M with %L, I-FABP and MPO associate with impaired growth, while also (like MPO associating with a systemic inflammation cluster of kynurenine, LBP, sCD14, SAA and K/T. Systemic evidence of LPS translocation associated with stunting, while markers of barrier disruption or repair (A1AT and Reg1 with low zonulin associated with fecal MPO and neopterin. We conclude that key noninvasive biomarkers of intestinal barrier disruption, LPS translocation and of intestinal and systemic inflammation can help elucidate how

  20. Serum C-Reactive Protein (CRP, Target for Therapy or Trouble?

    2006-01-01

    Full Text Available High sensitivity serum C-reactive protein (hs-CRP has come into clinical use as a marker of risk for cardiovascular disease (CVD. In addition to a role as a marker of disease, CRP has also been implicated in the pathogenesis of CVD. Specific small-molecule inhibitors of CRP have recently been developed with the intent of mitigating cardiac damage during acute myocardial infarction. However, the use of CRP, both as a risk marker and a disease target are controversial for several reasons. Serum hs-CRP concentrations can be elevated on the basis of genetics, female gender, and non-Caucasian ethnicity. It is not clear, in these contexts, that elevations of hs-CRP have any pathological significance. As a non-specific indicator of inflammation, CRP is also not a specific indicator of a single disease state such as cardiovascular disease but elevated concentrations can be seen in association with other comorbidities including obesity and pulmonary disease. In sharp contrast to the proposed inhibition of CRP for cardiovascular disease treatment, the infusion of CRP has been shown to have profound therapeutic benefits for autoimmune disease and septic shock. The balance between the risks and benefits of these competing views of the role of CRP in disease and disease therapy is reminiscent of the ongoing controversy regarding the use of non-steroidal anti-inflammatory drugs (NSAIDs for musculoskeletal disease and their cardiovascular side effects. Soon, NSAIDs may not be the only agents about which Rheumatologists and Cardiologists may spar.

    Chronic obstructive pulmonary disease (COPD) is currently a complex, multicomponent disorder. The COPD Assessment Test (CAT) has been increasingly used to assess COPD patients. This study aims to investigate the relationship between CAT and inflammation markers and other COPD components. We enrolled 110 stable COPD patients and 65 control subjects in this study. All patients completed the CAT questionnaire and the modified Medical Research Council (mMRC) dispnea scale. The quality of life of these patients was measured with St. George's Respiratory Questionnaire (SGRQ). Levels of TNFα, IL-6, CRP were determined in blood samples. In COPD patients, serum levels of TNFα (109.5 ± 58 pg/ml), IL-6 (10.3 ± 18 pg/ml), and C-reactive protein (CRP) (1.6 ± 1.7 mg/L) were found to be significantly higher compared to controls (TNF-α: 14.6 ± 18 pg/ml, IL-6: 2.14 ± 1.9 pg/ml, CRP: 0.4 ± 0.3mg/L, pCAT score correlated with GOLD spirometric stages, mMRC dyspnea score, number of exacerbations in the previous year and FEV1 (pCAT score (r=0.43, pCAT was observed. Systemic inflammation persists in the stable period of COPD. CRP, one of the inflammation markers, was correlated with the CAT. Further studies are required to confirm the relationship between CAT and biomarkers. Copyright © 2015 Sociedade Portuguesa de Pneumologia. Published by Elsevier España, S.L.U. All rights reserved.

    This study examined the influence of sex and playing position on the time-course of selected oxidative stress, inflammation and muscle damage markers following an official soccer match. Sixty professional soccer players (30 male and 30 female) were divided into three groups, according to their playing position: defenders, midfielders and attackers. Each group consisted of 10 male and 10 female players. Sixty healthy volunteers (30 males and 30 females) served as control. Blood samples were taken before and after the match and daily for five days after the match. Analysis of variance revealed different responses over time between sex and playing positions, as shown by the 3-way interaction, for creatine kinase (CK), protein carbonyls (PC), catalase, fibrinogen (FIB), uric acid (UA), lactate dehydrogenase (LDH), reduced glutathione, C-reactive protein and interleukin-6 (IL-6) (p position, for all oxidative, inflammatory and muscle damage indices (psexes, midfielders had higher peaks in all indices compared with defenders (p sex and playing position influence the time-course of selected oxidative stress, inflammation and muscle damage markers following an official soccer game. This information should be taken into account by practitioners for the design of training programs following match play.

  3. Pulmonary Remodeling in Equine Asthma: What Do We Know about Mediators of Inflammation in the Horse?

    2016-01-01

    Equine inflammatory airway disease (IAD) and recurrent airway obstruction (RAO) represent a spectrum of chronic inflammatory disease of the airways in horses resembling human asthma in many aspects. Therefore, both are now described as severity grades of equine asthma. Increasing evidence in horses and humans suggests that local pulmonary inflammation is influenced by systemic inflammatory processes and the other way around. Inflammation, coagulation, and fibrinolysis as well as extracellular remodeling show close interactions. Cytology of bronchoalveolar lavage fluid and tracheal wash is commonly used to evaluate the severity of local inflammation in the lung. Other mediators of inflammation, like interleukins involved in the chemotaxis of neutrophils, have been studied. Chronic obstructive pneumopathies lead to remodeling of bronchial walls and lung parenchyma, ultimately causing fibrosis. Matrix metalloproteinases (MMPs) are discussed as the most important proteolytic enzymes during remodeling in human medicine and increasing evidence exists for the horse as well. A systemic involvement has been shown for severe equine asthma by increased acute phase proteins like serum amyloid A and haptoglobin in peripheral blood during exacerbation. Studies focusing on these and further possible inflammatory markers for chronic respiratory disease in the horse are discussed in this review of the literature. PMID:28053371

    Full Text Available Background/Aims: One of the most common causes of anemia of chronic disease (ACD is chronic kidney disease. The main pathomechanism responsible for ACD is subclinical inflammation. The key element involved in iron metabolism is hepcidin, however, studies on new indices of iron status are in progress.The aim of the study was to assess the iron status in patients in early stages of chronic kidney disease, iron correlation with inflammation parameters and novel biomarkers of iron metabolism. Methods: The study included 69 patients. Standard laboratory measurements were used to measure the iron status, complete blood count, fibrinogen, prothrombin index, C-reactive protein concentration (CRP, creatinine, urea, uric acid. Commercially available kits were used to measure high-sensitivity CRP, interleukin 6 (IL-6, hepcidin-25, hemojuvelin, soluble transferrin receptor (sTfR, growth differentiation factor-15 (GDF-15 and zonulin. Results: Absolute iron deficiency was present in 17% of the patients, functional iron deficiency was present in 12% of the patients. Functional iron deficiency was associated with significantly higher serum levels of fibrinogen, ferritin, transferrin saturation, total iron binding capacity, hepcidin and older age relative to patients with absolute iron deficiency. In comparison with patients without iron deficiency, patients with functional iron deficiency were older, with lower prothrombin index, higher fibrinogen, CRP, hsCRP, sTfR, GDF-15, urea and lower eGFR. Hepcidin was predicted by markers of inflammation:ferritin, fibrinogen and IL-6. Conclusion: Inflammation is correlated with iron status. Novel biomarkers of iron metabolism might be useful to distinguish iron deficiency anemia connected with inflammation and absolute iron deficiency.

    Background. Advancing age, chronic inflammation, oxidative damage, and disorders of lipid metabolism are positively linked to the late-life cognitive impairment. Serum biomarkers may be associated with the cognitive status in older men. Methods. 440 old male subjects with different cognitive functions were recruited to investigate probable serum markers. Pearson Chi-Squared test, univariate analysis, and multivariate logistic regression analysis were performed to evaluate biomarkers which may be associated with cognitive status. Results. Levels of fundus atherosclerosis (AS) (P age (P age, AS levels, POD, IL-6, HDL-C, ApoA2, and ApoC2 were significantly related to cognitive status. Moreover, ApoA1 and ApoA2 were independently associated with cognitive impairment and late-life dementia. PMID:26682220

    It has been suggested that chronic infection with Helicobacter pylori (H. pylori), in particular infection with virulent strains producing the cytotoxin-associated protein CagA, may increase the risk of coronary heart disease by generation of a persistent low-grade inflammatory stimulus. We...... assessed the relation between serological markers of H. pylori infection and various markers of systemic inflammation in a population-based sample of 1834 men and women aged 18-88. A total of 39.3% of the sample had a positive IgG response, and among these a slight majority was CagA positive. Infection...... with H. pylori was unrelated to C-reactive protein and the leukocyte count, regardless of CagA status. There was an inverse relation between H. pylori infection and serum albumin. The adjusted OR (95% CI) of an albumin level in the bottom versus the top third were 2.2 (1.5-3.1) and 2.0 (1...

    -tocopherol [P = .003]) was associated with body condition score (BCS), but the association disappeared when cholesterol was included in the analyses. All markers of oxidative stress (MDA, oxLDL, and vitamin E) were positively associated with serum cholesterol concentration (P ≤ .04), but none were associated...... with clinical stage of MMVD. CONCLUSIONS: In conclusion, markers of oxidative stress are associated with sex, BCS, neuter status, and cholesterol. The results cannot confirm a relationship between oxidative stress and clinical stage of the disease in dogs with MMVD....

    The postthrombotic syndrome (PTS) is a chronic complication of deep vein thrombosis (DVT). Inflammation may contribute to its pathophysiology. We conducted a systematic review of studies that analyzed the association between biomarkers of inflammation and PTS in DVT patients. The electronic databases PubMed, EMBASE, Medline, Scopus and Web of Science were searched for studies published until March 2015 that measured blood inflammation biomarker levels in adult DVT patients and reported their association with PTS development. Two reviewers independently performed full text assessment and data extraction. Ten studies were included. Nine reported on the association between C-reactive protein and PTS; Interleukin (IL)-6 was measured in six studies; IL-8 in four studies; Intracellular adhesion molecule (ICAM)-1 in three studies; IL-10 and vascular cell adhesion molecule-1 in two studies; and monocyte chemotactic protein-1, matrix metalloprotease-9, P-Selectin, tumor necrosis factor α and erythrocyte sedimentation rate were measured in one study. Studies differed in terms of populations included, exclusion criteria, methods used for biomarker measurement and statistical measures of association between biomarkers and PTS. We were able to metaanalyze results only for IL-6 and found no significant association. Descriptively, ICAM-1 was significantly associated with PTS in two out of three studies that measured it. Other biomarkers did not demonstrate a significant association with PTS. Our systematic review found conflicting results regarding the role of inflammatory biomarkers as predictors of PTS. ICAM -1 appears to be a promising marker for further investigation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Occupational asthma is a common type of asthma caused by a specific agent in the workplace. The basic alteration of occupational asthma is airways inflammation. Although most patients with occupational asthma are mature adults, there is evidence that airways inflammation starts soon after inception of exposure, including during apprenticeship. Airways hyper responsiveness to methacholine is a valid surrogate marker of airways inflammation, which has proved useful in occupational epidemiology. But it is time-consuming, requires active subject's cooperation and is not readily feasible. Other non-invasive and potentially more useful tests include the forced oscillation technique, measurement of fraction exhaled nitric oxide, and eosinophils count in nasal lavage fluid. This study aims to investigate early development of airways inflammation and asthma-like symptoms in apprentice bakers, pastry-makers and hairdressers, three populations at risk of occupational asthma whose work-related exposures involve agents of different nature. The objectives are to (i) examine the performance of the non-invasive tests cited above in detecting early airways inflammation that might eventually develop into occupational asthma; and (ii) evaluate whether, and how, constitutional (e.g. atopy) and behavioural (e.g. smoking) risk factors for occupational asthma modulate the effects of allergenic and/or irritative substances involved in these occupations. This paper presents the study rationale and detailed protocol. Among 441 volunteers included at the first visit, 354 attended the fourth one. Drop outs were investigated and showed unrelated to the study outcome. Sample size and follow-up participation rates suggest that the data collected in this study will allow it to meet its objectives.

    Posttraumatic stress disorder (PTSD) is associated with increased inflammation and comorbid medical conditions. However, study findings for individual inflammatory marker levels have been inconsistent. Some research suggests that resilience may play a role in decreased inflammation. A polymorphism in the promoter region of the tumor necrosis factor α gene (TNFα), TNFA -308 (rs1800629) is associated with psychiatric illness but its role in PTSD is yet to be elucidated. This study investigates a key inflammatory marker, TNFα, for its role in PTSD severity. In a cohort of trauma-exposed Vietnam War veterans (n=299; 159 cases, 140 controls) TNF α serum levels and TNFα polymorphism rs1800629 were correlated with PTSD severity and resilience scores. The polymorphism was associated with PTSD severity (p=0.045). There were significant group differences between cases and controls with regards to serum TNFα levels (p=0.036). Significant correlations were found between PTSD severity and elevated TNFα levels (r=0.153; p=0.009), and between resilience and decreased TNFα levels at a trend level (p=0.08) across the entire cohort. These relationships were non-significant after controlling for covariates. In the PTSD diagnostic group, a correlation of TNFα and PTSD severity was observed on a trend level (p=0.06), the relationship between TNFα and resilience remained non-significant. To our knowledge, this is the first time rs1800629 has been investigated in PTSD contributing to a growing body of literature that identifies the GG as a risk genotype for psychiatric disorders in Caucasian cohorts. However, more research is needed to replicate our results in larger, equally well-characterized cohorts. The relationship between serum TNFα levels and PTSD severity and resilience requires further investigation. Crown Copyright © 2017. Published by Elsevier Inc. All rights reserved.

    Serum high-sensitivity C-reactive protein (hsC-rp) is a non-specific marker of inflammation. Elevated hsC-rp levels are found in subjects with cardiovascular diseases (CVDs). Periodontitis may influence hsC-rp levels. To assess periodontal status and hsC-rp serum levels in consecutive subjects hospitalized and diagnosed with acute myocardial infarction (AMI) (n=85) and in a group of carefully matched subjects (gender, age social, ethnic, and smoking habits) without clinical evidence of CVD (n=63). hsC-rp levels, other routine serum values, and clinical periodontal conditions were studied. Subjects with AMI had higher hsC-rp levels than control subjects (pperiodontitis (30% or more sites with>4.0 mm loss of alveolar bone) had serum hsC-rp>1.8 mg/l was 1.5 (95% CI: 1.1-7.3, pperiodontal parameters in an explanatory model to hsC-rp values. Only the serum leucocyte (white blood cell (WBC)) counts were explanatory to hsC-rp values (beta standard coefficient=0.45, t=3.2, pperiodontitis (pperiodontitis in subjects with no evidence of CVD. (3) Periodontal parameters are not explanatory to elevated serum hsC-rp values if serum WBC and low-density lipoprotein counts are included in the regression model.

    Serum and bronchoalveolar fluid IL-6 are increased in patients with acute respiratory distress syndrome (ARDS) and predict prolonged mechanical ventilation and poor outcomes, although the role of intra-alveolar IL-6 in indirect lung injury is unknown. We investigated the role of endogenous and exogenous intra-alveolar IL-6 in AKI-mediated lung injury (indirect lung injury), intraperitoneal (IP) endotoxin administration (indirect lung injury) and, for comparison, intratracheal (IT) endotoxin administration (direct lung injury) with the hypothesis that IL-6 would exert a pro-inflammatory effect in these causes of acute lung inflammation. Bronchoalveolar cytokines (IL-6, CXCL1, TNF-α, IL-1β, and IL-10), BAL fluid neutrophils, lung inflammation (lung cytokines, MPO activity [a biochemical marker of neutrophil infiltration]), and serum cytokines were determined in adult male C57Bl/6 mice with no intervention or 4 hours after ischemic AKI (22 minutes of renal pedicle clamping), IP endotoxin (10 µg), or IT endotoxin (80 µg) with and without intratracheal (IT) IL-6 (25 ng or 200 ng) treatment. Lung inflammation was similar after AKI, IP endotoxin, and IT endotoxin. BAL fluid IL-6 was markedly increased after IT endotoxin, and not increased after AKI or IP endotoxin. Unexpectedly, IT IL-6 exerted an anti-inflammatory effect in healthy mice characterized by reduced BAL fluid cytokines. IT IL-6 also exerted an anti-inflammatory effect in IT endotoxin characterized by reduced BAL fluid cytokines and lung inflammation; IT IL-6 had no effect on lung inflammation in AKI or IP endotoxin. IL-6 exerts an anti-inflammatory effect in direct lung injury from IT endotoxin, yet has no role in the pathogenesis or treatment of indirect lung injury from AKI or IP endotoxin. Since intra-alveolar inflammation is important in the pathogenesis of direct, but not indirect, causes of lung inflammation, IT anti-inflammatory treatments may have a role in direct, but not indirect, causes of ARDS.

    Full Text Available It was reported that C-reactive protein (CRP levels increase in parallel with the progression of chronic liver diseases, such as chronic hepatitis and liver cirrhosis. Inflammatory markers, such as high sensitive C-reactive protein (hsCRP, ferritin, transferrin, albumin, alpha-1 acid glycoprotein (AAG, alpha-2 macroglobulin (AMG, alpha-1 anti-trypsin (AAT and lipoprotein a [Lp(a] were measured in coronary artery disease patients (CAD and CAD patients with non-alcoholic steatohepatitis (NASH. In the present preliminary study an attempt was made to study whether there is an increase in the levels of CRP in CAD patients associated with NASH. CAD patients showed an increase in CRP and serum ferritin levels. In CAD patients with NASH along with an increase in the levels of serum ferittin (p<0.001, the levels of serum AMG and ceruloplasmin (CP were also increased (p<0.01. The CAD patients with NASH had a higher proportion of diabetes, hypertension and dyslipidaemia compared to CAD patients. But how this difference contributes to the elevation in acute inflammatory markers particularly AMG and CP levels in CAD patients with NASH cannot be explained. This study shows that a substantial number of CAD patients may be associated with NASH. Non-invasive simple parameters that reflect the degree of inflammation and fibrosis of the liver in patients with NASH would facilitate improved understanding and treatment of the disease. Further studies may be necessary to evaluate the percentage of NASH patients progressing to CAD.

    Full Text Available Inflammatory atherosclerosis is increased in subjects with type 1 diabetes mellitus (T1DM. Normally high-density lipoproteins (HDL protect against atherosclerosis; however, in the presence of serum amyloid-A- (SAA- related inflammation this property may be reduced. Fasting blood was obtained from fifty subjects with T1DM, together with fifty age, gender and BMI matched control subjects. HDL was subfractionated into HDL2 and HDL3 by rapid ultracentrifugation. Serum-hsCRP and serum-, HDL2-, and HDL3-SAA were measured by ELISAs. Compared to control subjects, SAA was increased in T1DM subjects, nonsignificantly in serum (P=0.088, and significantly in HDL2(P=0.003 and HDL3(P=0.005. When the T1DM group were separated according to mean HbA1c (8.34%, serum-SAA and HDL3-SAA levels were higher in the T1DM subjects with HbA1c ≥ 8.34%, compared to when HbA1c was 0.05. This cross-sectional study demonstrated increased SAA-related inflammation in subjects with T1DM that was augmented by poor glycaemic control. We suggest that SAA is a useful inflammatory biomarker in T1DM, which may contribute to their increased atherosclerosis risk.

    Social support is associated with cardiovascular disease mortality, however, the physiologic mechanisms underlying this relationship remains unspecified. This study evaluated the association of social support with inflammatory markers associated with cardiovascular risk: C-reactive protein (CRP), interleukin-6 (IL-6), and fibrinogen. We evaluated two competing models of the support-inflammation relationship: first, that low social support is directly associated with inflammation, and second, that high support acts to buffer the effect of stress on inflammation. Using data from the baseline interview of the Multi-Ethnic Study of Atherosclerosis (N = 6814, 53% female, age 45-84 years) we assessed the independent and interacting associations of social support and stress with inflammation. Social support was measured by the emotional social support index. Stressors in multiple domains (work, family, finances, interpersonal) were assessed. Serum CRP, IL-6, and fibrinogen were analyzed from fasting samples using high-sensitivity assays. Multivariate linear regression, including models stratified by gender and age group (45-64 and 65-84 years), was used to assess the direct and buffering relationships between social support, stress, and inflammation. In bivariate analyses low social support was associated with higher levels of all three markers. In adjusted models, low support was associated with higher lnCRP (B: 0.15, 95% CI: 0.01, 0.30) among men but not women. High social support buffered the relationship between stress and CRP among middle-aged women only (P for interaction 0.042). Overall, social support was only modestly associated with inflammation in this relatively healthy sample, and these relationships varied by age and gender. Copyright © 2010 Elsevier Inc.

    The most important reason for the non-approval and withdrawal of drugs by the Food and Drug Administration is hepatotoxicity. Therefore, this study was undertaken to evaluate the protective effects of hesperidin against cyclophosphamide (CYP)-induced hepatotoxicity in Wistar rats. The rats received a single intraperitoneal dose of CYP of 200 mg/kg body mass, followed by treatment with hesperidin, orally, at doses of 25 and 50 mg/kg for 11 consecutive days. CYP induced hepatic damage, as evidenced by the significantly elevated levels of serum pro-inflammatory cytokines, serum transaminases, liver lipid peroxidation, and nitric oxide. As a consequence, there was reduced glutathione content, and the activities of the antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase, were markedly reduced. In addition, CYP administration induced a considerable downregulation of peroxisome proliferator activated receptor gamma (PPARγ) and upregulation of nuclear factor-kappa B (NF-κB) and inducible nitric oxide synthase (iNOS) mRNA expression. Hesperidin, in a dose-dependent manner, rejuvenated the altered markers to an almost normal state. In conclusion, hesperidin showed a potent protective effect against CYP-induced oxidative stress and inflammation leading to hepatotoxicity. The study suggests that hesperidin exerts its protective effect against CYP-induced hepatotoxicity through upregulation of hepatic PPARγ expression and abrogation of inflammation and oxidative stress.

    Although a liver stiffness measurement-based model can precisely predict significant intrahepatic inflammation, transient elastography is not commonly available in a primary care center. Additionally, high body mass index and bilirubinemia have notable effects on the accuracy of transient elastography. The present study aimed to create a noninvasive scoring system for the prediction of intrahepatic inflammatory activity related to chronic hepatitis B, without the aid of transient elastography. A total of 396 patients with chronic hepatitis B were enrolled in the present study. Liver biopsies were performed, liver histology was scored using the Scheuer scoring system, and serum markers and liver function were investigated. Inflammatory activity scoring models were constructed for both hepatitis B envelope antigen (+) and hepatitis B envelope antigen (-) patients. The sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve were 86.00%, 84.80%, 62.32%, 95.39%, and 0.9219, respectively, in the hepatitis B envelope antigen (+) group and 91.89%, 89.86%, 70.83%, 97.64%, and 0.9691, respectively, in the hepatitis B envelope antigen (-) group. Significant inflammation related to chronic hepatitis B can be predicted with satisfactory accuracy by using our logistic regression-based scoring system.

    Introduction: Several mechanisms have been proposed to explain the adverse effect of obesity on quality of life among women with breast cancer, including alteration in some inflammatory markers. The aim of this study was to determine the status of serum levels of leptin, IL-6 and CRP in obese, overweight and normal weight breast cancer survivors in order to determine the relationship between inflammatory markers’ levels and obesity. Materials and methods: This cross-sectional study was done on 75 women with breast cancer, 30 obese, 15 overweight and 30 normal weight patients. Serum leptin, IL-6, CRP, total protein, albumin and lipid profile as well as anthropometric parameters were measured in three groups. Results: Serum leptin levels of obese patients were significantly higher than those of overweight and normal weight patients ( P < 0.05). Higher serum CRP and lower albumin levels were observed in obese patients in comparison with normal weight patients ( P < 0.05). HDL-C level was significantly different between overweight and normal weight patients ( P < 0.05). Significant differences in serum IL-6 levels were not observed between the study groups ( P > 0.05). Moreover, multiple regression analysis showed that leptin was significantly associated with BMI ( P < 0.001), while albumin was negatively correlated with BMI ( P < 0.05). CRP levels were significantly correlated with BMI and waist-to-hip ratio (WHR) ( P < 0.05). Conclusions: In conclusion, high leptin levels and alteration in acute phase proteins in obese patients may exaggerate the inflammation status. As inflammation has the potential to increase the susceptibility of the patients to metastasis development, it is necessary to decline its rate.

    To evaluate changes of serum leptin levels in patients with viral hepatitis C(HCV), serum leptin levels were determined by RIA in 65 patients with viral chronic hepatitis C and in 80 control subjects ,liver function (ALT, AST) , glucose (Glu) , and total cholesterol (TC) were evaluated too. Campared with controls, the levels of serum leptin were significantly increased in patients with HCV (P 0.05). The levels of serum leptin increased in patients with HCV, which correlates positively with the severity of liver inflammation, so that leptin can be regarded as an index which reflects the severity of liver inflammation.

    Objective To compare short-term effects of fine particles (PM2.5; aerodynamic diameter <2.5 µm) from different sources on the blood levels of markers of systemic inflammation. Methods We followed a panel of 52 ischaemic heart disease patients from 15 November 2005 to 21 April 2006 with clinic visits in every second week in the city of Kotka, Finland, and determined nine inflammatory markers from blood samples. In addition, we monitored outdoor air pollution at a fixed site during the study period and conducted a source apportionment of PM2.5 using the Environmental Protection Agency's model EPA PMF 3.0. We then analysed associations between levels of source-specific PM2.5 and markers of systemic inflammation using linear mixed models. Results We identified five source categories: regional and long-range transport (LRT), traffic, biomass combustion, sea salt, and pulp industry. We found most evidence for the relation of air pollution and inflammation in LRT, traffic and biomass combustion; the most relevant inflammation markers were C-reactive protein, interleukin-12 and myeloperoxidase. Sea salt was not positively associated with any of the inflammatory markers. Conclusions Results suggest that PM2.5 from several sources, such as biomass combustion and traffic, are promoters of systemic inflammation, a risk factor for cardiovascular diseases. PMID:25479755

    Full Text Available Abstract Background Even though it has been suggested that antiretroviral therapy has an impact on severe hypovitaminosis D (SHD in HIV infected patients, it could be speculated that the different levels of residual inflammation on HAART (Highly Active Anti Retroviral Therapy could contribute to SHD and aggravate bone catabolism in these patients. Methods A cross-sectional study was carried out in an unselected cohort of 263 HIV infected outpatients consulting during Spring 2010. Clinical examinations were performed and medical history, food habits, sun exposure and addictions were collected. Fasting blood samples were taken for immunological, virological, inflammation, endocrine and bone markers evaluations. Results Ninety-five (36% patients had SHD. In univariate analysis, a significant and positive association was found between SHD and IL6 (p = 0.001, hsCRP (p = 0.04, increased serum C-Telopeptides X (CTX (p = 0.005 and Parathyroid Hormon (PTH (p Conclusions SHD is frequent and correlates with inflammation in HIV infected patients. Since SHD is also associated with falls and increased bone catabolism, it may be of interest to take into account not only the type of antiretroviral therapy but also the residual inflammation on HAART in order to assess functional and bone risks. This finding also suggests that vitamin D supplementation may be beneficial in these HIV-infected patients.

    To evaluate the agreement of risk categorization for Down syndrome screening between ultrasound scan-based gestational age (GA) and last menstrual period-based gestational age in both first and second trimesters by maternal serum markers. Data comprising 4,055 and 4,016 cases of first and second trimester screening were used. The maternal serum markers were analyzed using the ultrasound-based GA and menstrual age. The subjects whose menstrual age and ultrasound-based GA fell in different trimesters were excluded because the risk could not be calculated due to the different serum markers used in each trimester. The agreement of risk categorization for fetal Down syndrome was evaluated. The agreement of Down syndrome screening in the first and the second trimesters were 92.7% and 89%, respectively. The study found a good agreement of risk categorization by Kappa index, which was 0.615 for the overall screening. The menstrual age had a slight decrease in the detection rate and a lower false-positive rate. Menstrual age is acceptable in cases of accurate last menstrual period. However, in places where ultrasonography is not readily available, gestational age estimation by menstrual age along with clinical examination that corresponds to the gestational age can be reliable.

    Full Text Available Objectives-Methods. Visceral leishmaniasis (VL is characterized by chronicity and relapses despite efficacious treatment. Acute and chronic inflammatory processes and concomitant disturbances in cell adhesion characterize the pathogenesis of the disease. To investigate these processes further we measured adhesion molecules (L-selectin, ICAM-1 and VCAM-1 serum levels in 16 children with VL, as well as in 20 healthy controls. All children were treated with liposomal amphotericin B (3 mg/kg on days 1 to 5, 14, and 21. Measurements were performed at days 0, 15 and 30. Results. All children responded well to treatment in both clinical and laboratory terms. In three cases relapse occurred at 3, 5 and 6 months after treatment had ended. Serum L-selectin levels, both pre-treatment and post-treatment, did not significantly differ between patients and controls. VCAM-1 and ICAM-1 median levels were similar in patients and controls (P>0.05 at day 0 and significantly increased at day 15 (P0.05, but not in the 3 patients who relapsed (P<0.05. Conclusions. Despite the small number of the patients, the changes in VCAM-1 and ICAM-1 levels indicate the anti-parasite activation of the immune system during the course of VL and the effect of treatment. Decline in post-treatment serum VCAM-1 and ICAM-1 levels might be used as a marker of treatment efficacy in childhood VL.

    The interplay between hepatitis B (HBV) and Delta (HDV) viruses is complex and not always characterized during chronic HDV infection. We assessed the clinical usefulness of new quantitative assays for HBV and HDV serum markers in a retrospective cross-sectional study. Sera obtained from 122 HDV-genotype-1 and HBV-genotype-D co-infected, anti-HIV-negative patients [71 males; median age 49.8 (21.7-66.9) years], recruited consecutively in two geographic areas (Italy 69 patients, Romania 53) with different HBV and HDV epidemiology, were tested for HBsAg, HBV-DNA, HBcrAg, total anti-HBc, HDV-RNA, IgM and total anti-HDV using quantitative assays. Cirrhosis, that showed comparable prevalence in the two cohorts, was diagnosed in 97 of 122 (79.5%) patients. At multivariate analysis, cirrhosis was associated with lower total anti-HBc/IgM-anti-HDV ratio (OR 0.990, 95%CI 0.981-0.999, P=0.038), whereas disease activity was associated with higher total anti-HDV (OR 10.105, 95% CI 1.671-61.107, P=0.012) and HDV-RNA levels (OR 2.366, 95% CI 1.456-3.844, P=0.001). HDV-RNA serum levels showed a positive correlation with HBV-DNA (ρ=0.276, P=0.005), HBsAg (ρ=0.404, PHBV and HDV serum markers identifies specific patterns associated with activity and stage of chronic hepatitis D (CHD). HDV pathogenicity depends on the underlying active HBV infection in spite of the inhibition of its replication. HDV-RNA, IgM anti-HDV, total anti-HDV, total anti-HBc, HBsAg and HBcrAg serum levels qualify for prospective studies to predict progressive CHD and identify candidates to antiviral therapy.

    Simvastatin (SMV) has been shown to exhibit promising anti-inflammatory properties alongside its classic cholesterol lowering action. We tested these emerging effects in a major thermal injury mouse model (3rd degree scald, ~20% TBSA) with previously documented, inflammation-mediated intestinal defects. Neutrophil extracellular traps (NETs) inflammation measurement methods were used alongside classic gut mucosa inflammation and leakiness measurements with exogenous melatonin treatment as a positive control. Our hypothesis is that simvastatin has protective therapeutic effects against early postburn gut mucosa inflammation and leakiness. To test this hypothesis, we compared untreated thermal injury (TI) adult male mice with TI littermates treated with simvastatin (0.2 mg/kg i.p., TI + SMV) immediately following burn injury and two hours before being sacrificed the day after; melatonin-treated (Mel) (1.86 mg/kg i.p., TI + Mel) mice were compared as a positive control. Mice were assessed for the following: (1) tissue oxidation and neutrophil infiltration in terminal ileum mucosa using classic carbonyl, Gr-1, and myeloperoxidase immunohistochemical or biochemical assays, (2) NETosis in terminal ileum and colon mucosa homogenates and peritoneal and fluid blood samples utilizing flow cytometric analyses of the surrogate NETosis biomarkers, picogreen and Gr-1, and (3) transepithelial gut leakiness as measured in terminal ileum and colon with FITC-dextran and transepithelial electrical resistance (TEER). Our results reveal that simvastatin and melatonin exhibit consistently comparable therapeutic protective effects against the following: (1) gut mucosa oxidative stress as revealed in the terminal ileum by markers of protein carbonylation as well as myeloperoxidase (MPO) and Gr-1 infiltration, (2) NETosis as revealed in the gut milieu, peritoneal lavage and plasma utilizing picogreen and Gr-1 flow cytometry and microscopy, and (3) transepithelial gut leakiness as

    The inflammatory response is integral to maintaining health by functioning to resist microbial infection and repair tissue damage. Large numbers of neutrophils are recruited to inflammatory sites to neutralize invading bacteria through phagocytosis and the release of proteases and reactive oxygen species into the extracellular environment. Removal of the original inflammatory stimulus must be accompanied by resolution of the inflammatory response, including neutrophil clearance, to prevent inadvertent tissue damage. Neutrophil apoptosis and its temporary inhibition by survival signals provides a target for anti-inflammatory therapeutics, making it essential to better understand this process. GM-CSF, a neutrophil survival factor, causes a significant increase in mRNA levels for the known anti-apoptotic protein serum and glucocorticoid-regulated kinase 1 (SGK1). We have characterized the expression patterns and regulation of SGK family members in human neutrophils and shown that inhibition of SGK activity completely abrogates the antiapoptotic effect of GM-CSF. Using a transgenic zebrafish model, we have disrupted sgk1 gene function and shown this specifically delays inflammation resolution, without altering neutrophil recruitment to inflammatory sites in vivo. These data suggest SGK1 plays a key role in regulating neutrophil survival signaling and thus may prove a valuable therapeutic target for the treatment of inflammatory disease.

    Full Text Available Abstract Background Occupational asthma is a common type of asthma caused by a specific agent in the workplace. The basic alteration of occupational asthma is airways inflammation. Although most patients with occupational asthma are mature adults, there is evidence that airways inflammation starts soon after inception of exposure, including during apprenticeship. Airways hyper responsiveness to methacholine is a valid surrogate marker of airways inflammation, which has proved useful in occupational epidemiology. But it is time-consuming, requires active subject's cooperation and is not readily feasible. Other non-invasive and potentially more useful tests include the forced oscillation technique, measurement of fraction exhaled nitric oxide, and eosinophils count in nasal lavage fluid. Methods and design This study aims to investigate early development of airways inflammation and asthma-like symptoms in apprentice bakers, pastry-makers and hairdressers, three populations at risk of occupational asthma whose work-related exposures involve agents of different nature. The objectives are to (i examine the performance of the non-invasive tests cited above in detecting early airways inflammation that might eventually develop into occupational asthma; and (ii evaluate whether, and how, constitutional (e.g. atopy and behavioural (e.g. smoking risk factors for occupational asthma modulate the effects of allergenic and/or irritative substances involved in these occupations. This paper presents the study rationale and detailed protocol. Discussion Among 441 volunteers included at the first visit, 354 attended the fourth one. Drop outs were investigated and showed unrelated to the study outcome. Sample size and follow-up participation rates suggest that the data collected in this study will allow it to meet its objectives.

    Full Text Available Abstract Background Chronic kidney disease (CKD is a newly recognized high-risk condition for cardiovascular disease (CVD, and previous studies reported the changes in inflammation and oxidative stress in advanced stages of CKD. We compared the levels of serum biomarkers for inflammation and oxidative stress between subjects with normal and mildly reduced glomerular filtration rate (GFR. Methods The subjects were 182 participants of a health check-up program including those with normal (≥ 90 mL/min/1.73 m2, N = 79 and mildly reduced eGFR (60-89 mL/min/1.73 m2, N = 103 which was calculated based on serum creatinine, age and sex. We excluded those with reduced eGFR 2. No one had proteinuria. We measured serum levels of C-reactive protein (CRP and thioredoxin (TRX as the markers of inflammation and oxidative stress, respectively. Results As compared with subjects with normal eGFR, those with mildly reduced eGFR had increased levels of both CRP and TRX. Also, eGFR was inversely correlated with these biomarkers. The associations of eGFR with these biomarkers remained significant after adjustment for age and sex. When adjustment was done for eight possible confounders, CRP showed significant association with systolic blood pressure, high density lipoprotein cholesterol (HDL-C and non-HDL-C, whereas TRX was associated with sex significantly, and with eGFR and systolic blood pressure at borderline significance. Conclusions We showed the increased levels of CRP and TRX in subjects with mildly reduced eGFR. The eGFR-CRP link and the eGFR-TRX link appeared to be mediated, at least partly, by the alterations in blood pressure and plasma lipids in these subjects.

This study was conducted to determine the diagnostic value of serum interleukin (IL-6 and IL-8 in children with acute pyelonephritis. &lt;b&gt;Methods:&lt;/b&gt; Eighty seven patients between 1 month to 12 years old with urinary tract infection (UTI were divided into 2 groups based on the result of 99m-technetium dimercapto-succinic acid (DMSA renal scan: acute pyelonephritis (n=37 and lower UTI (n=50 groups. White blood cell (WBC count, neutrophil (Neutl count, erythrocyte sedimentation rate (ESR, C-reactive protein (CRP concentration, platelet count, and serum IL-6 and IL-8 concentrations of both groups were measured and compared . &lt;b&gt;Results:&lt;/b&gt; There was a significant difference between two groups regarding WBC count, Neutl count, ESR, and CRP concentration (P&lt;0.05. In addition, the difference between the two groups regarding serum IL-6 and IL-8 concentrations was not significant (IL-6, 60 and 35.4 pg/mL and IL-8, 404 and 617 pg/mL, respectively. The sensitivity and specificity of serum IL-6 and IL-8 for diagnosis of acute pyelonephritis were 73%, 42% and 78%, 32%, respectively. Sensitivity, specificity, negative and positive predictive values of serum IL-6 and IL-8 were less than those of acute phase serum reactants such as CRP. &lt;b&gt;Conclusion:&lt;/b&gt; This study showed that there was no significant difference between acute pyelonephritis and lower UTI groups regarding serum IL-6 and IL-8 levels. Therefore, despite confirming results of previous studies, it seems that IL-6 and IL-8 are not suitable markers for differentiating between acute pyelonephritis and lower UTI.

    Localized scleroderma is an autoimmune disease primarily affecting the skin. The cause of disease remains unexplained although environmental factors are implicated, which are likely to be responsible for activation of the endothelium and subsequent inflammation leading to excessive synthesis of collagen and extracellular matrix components. To determine concentrations of interleukin (IL)-27, transforming growth factor (TGF)-β1, TGF-β2, IL-6, and sIL-6R in patients with localized scleroderma compared to controls and to assess the relations between their levels and laboratory markers. The study encompassed 17 females with localized scleroderma (aged 25-67). The control group consisted of 30 age-matched healthy women. The blood was sampled from the basilic vein. Serum levels of cytokines were determined using ELISA. The TGF-β2 levels were found to be significantly lower in patients with localized scleroderma compared to controls. Concentrations of TGF-β1 were decreased in scleroderma patients when compared to controls but without statistical significance. There were no significant differences in serum IL-6, sIL-6R and IL-27 levels between patients and the control group; however, we found a significant positive correlation between the level of sIL-6 and ESR among subjects with localized scleroderma. The findings of decreased serum levels of TGF-β1 and TGF-β2 in patients with localized scleroderma demonstrate a possible association of these cytokines with pathogenesis of the disease. The results suggest also that sIL-6R is likely to be involved in inflammation in patients with localized scleroderma.

    Full Text Available Systemic inflammation is an integral part of chronic obstructive pulmonary disease (COPD, and air pollution is associated with cardiorespiratory mortality, yet the interrelationships are not fully defined. We examined associations between nitrogen dioxide (NO2 exposure (as a marker of traffic-related air pollution and pro-inflammatory cytokines, and investigated effect modification and mediation by post-bronchodilator airflow obstruction (post-BD-AO and cardiovascular risk. Data from middle-aged participants in the Tasmanian Longitudinal Health Study (TAHS, n = 1389 were analyzed by multivariable logistic regression, using serum interleukin (IL-6, IL-8 and tumor necrosis factor-α (TNF-α as the outcome. Mean annual NO2 exposure was estimated at residential addresses using a validated satellite-based land-use regression model. Post-BD-AO was defined by post-BD forced expiratory ratio (FEV1/FVC < lower limit of normal, and cardiovascular risk by a history of either cerebrovascular or ischaemic heart disease. We found a positive association with increasing serum IL-6 concentration (geometric mean 1.20 (95% CI: 1.1 to 1.3, p = 0.001 per quartile increase in NO2. This was predominantly a direct relationship, with little evidence for either effect modification or mediation via post-BD-AO, or for the small subgroup who reported cardiovascular events. However, there was some evidence consistent with serum IL-6 being on the causal pathway between NO2 and cardiovascular risk. These findings raise the possibility that the interplay between air pollution and systemic inflammation may differ between post-BD airflow obstruction and cardiovascular diseases.

    The cause of cerebral small vessel disease is not fully understood, yet it is important, accounting for about 25% of all strokes. It also increases the risk of having another stroke and contributes to about 40% of dementias. Various processes have been implicated, including microatheroma, endothelial dysfunction and inflammation. A previous review investigated endothelial dysfunction in lacunar stroke versus mostly non-stroke controls while another looked at markers of inflammation and endothelial damage in ischaemic stroke in general. We have focused on blood markers between clinically evident lacunar stroke and other subtypes of ischaemic stroke, thereby controlling for stroke in general. We systematically assessed the literature for studies comparing blood markers of coagulation, fibrinolysis, endothelial dysfunction and inflammation in lacunar stroke versus non-stroke controls or other ischaemic stroke subtypes. We assessed the quality of included papers and meta-analysed results. We split the analysis on time of blood draw in relation to the stroke. We identified 1,468 full papers of which 42 were eligible for inclusion, including 4,816 ischaemic strokes, of which 2,196 were lacunar and 2,500 non-stroke controls. Most studies subtyped stroke using TOAST. The definition of lacunar stroke varied between studies. Markers of coagulation/fibrinolysis (tissue plasminogen activator (tPA), plasminogen activator inhibitor (PAI), fibrinogen, D-dimer) were higher in lacunar stroke versus non-stroke although fibrinogen was no different to non-stroke in the acute phase. tPA and PAI were no different between lacunar and non-lacunar stroke. Fibrinogen and D-dimer were significantly lower in lacunar stroke compared to other ischaemic strokes, both acutely and chronically. Markers of endothelial dysfunction (homocysteine, von Willebrand Factor (vWF), E-selectin, P-selectin, intercellular adhesion molecule-1 (ICAM), vascular cellular adhesion molecule-1 (VCAM)) were higher or

    Full Text Available Squamous cell carcinoma of head and neck (SCCHN is often asymptomatic until it reaches the advanced stage. Currently, there are no available markers that can accurately predict the risk of progression of epithelial dysplasia to squamous cell carcinoma. The purpose of the study was to evaluate the feasibility of using the level of adenylyl cyclase-associated protein 1 (CAP-1 in the blood serum to identify groups of increased risk of cancer in patients with chronic laryngeal and hypopharyngeal hyperplasia associated with epithelial dysplasia. Material and methods. The blood serums from 45 patients with SCCHN (T1–4N0–3M0, 12 patients  with chronic inflammatory laryngeal and hypopharyngeal diseases and 15 heath subjects were examined. The blood analysis was performed using the CAP1 ELISA kit (Cusabio on the Biochrom Anthos 2020 Microplate IEA Reader. Results. The serum level of САР1 was higher by 75 % in patients with SCCHN (Т1N0M0 than in patients with chronic hyperplastic laryngitis. Moreover, differences in the serum level of САР1 were observed between healthy subjects and patients with chronic laryngeal hyperplasia. In SCCHN patients with regional metastases, CAP1 concentration in the blood serum was 2 times higher compared to that observed in SCCHN patients without regional metastases (p≤0.01. Conclusion. The study results showed the feasibility of using the level of CAP1 for distinguishing patients with chronic hyperplastic laryngitis from those with laryngeal cancer, as well as for early detection of SCCHN and the development of new method for prediction of disease.

    Full Text Available We aimed to evaluate the value of immunohistochemical markers and serum CA125 in predicting the risk of lymph node metastasis (LNM in women with endometrial cancer and to identify a low-risk group of LNM. The medical records of 370 patients with endometrial endometrioid adenocarcinoma who underwent surgical staging in the Obstetrics & Gynecology Hospital of Fudan University were collected and retrospectively reviewed. Immunohistochemical markers were screened. A model using serum cancer antigen 125 (CA125 level, the immunohistochemical markers progesterone receptor (PR and Ki67 was created for prediction of LNM. A predicted probability of 4% among these patients was defined as low risk. The developed model was externally validated in 200 patients from Shanghai Cancer Center. The efficiency of the model was compared with three other reported prediction models. Patients with serum CA125 50% and Ki67 < 40% in cancer lesion were defined as low risk for LNM. The model showed good discrimination with an area under the receiver operating characteristic curve of 0.82. The model classified 61.9% (229/370 of patients as being at low risk for LNM. Among these 229 patients, 6 patients (2.6% had LNM and the negative predictive value was 97.4% (223/229. The sensitivity and specificity of the model were 84.6% and 67.4% respectively. In the validation cohort, the model classified 59.5% (119/200 of patients as low-risk, 3 out of these 119 patients (2.5% has LNM. Our model showed a predictive power similar to those of two previously reported prediction models. The prediction model using serum CA125 and the immunohistochemical markers PR and Ki67 is useful to predict patients with a low risk of LNM and has the potential to provide valuable guidance to clinicians in the treatment of patients with endometrioid endometrial cancer.

    Objective The aim of this study was to estimate the heritability (h2) and genetic correlation (ρG) between GERD symptoms severity, metabolic syndrome components, and inflammation markers in Mexican families. Methods Cross-sectional study which included 32 extended families resident in Mexico City. GERD symptoms severity was assessed by the ReQuest in Practice questionnaire. Heritability and genetic correlation were determined using the Sequential Oligogenic Linkage Analysis Routines software. Results 585 subjects were included, the mean age was 42 (±16.7) years, 57% were women. The heritability of the severity of some GERD symptoms was h2 = 0.27, 0.27, 0.37, and 0.34 (p-value metabolic syndrome components ranged from 0.40 for fasting plasma glucose to 0.61 for body mass index and diabetes mellitus. The heritability for fibrinogen and C-reactive protein was 0.64 and 0.38, respectively. Statistically significant genetic correlations were found between acidity complaints and fasting plasma glucose (ρG = 0.40); sleep disturbances and fasting plasma glucose (ρG = 0.36); acidity complaints and diabetes mellitus (ρG = 0.49) and between total ReQuest score and fasting plasma glucose (ρG = 0.43). The rest of metabolic syndrome components did not correlate with GERD symptoms. Conclusion Genetic factors substantially explain the phenotypic variance of the severity of some GERD symptoms, metabolic syndrome components and inflammation markers. Observed genetic correlations suggest that these phenotypes share common genes. These findings suggest conducting further investigation, as the determination of a linkage analysis in order to identify regions of susceptibility for developing of GERD and metabolic syndrome.

    The purpose of this study is to investigate the diagnostic value of transvaginal sonograph (TVS), color Doppler, and serum tumor marker CA125, CEA, and AFP in ovarian cancer. From June, 2011 to May, 2013, 102 cases with adnexal mass were recruited in this study (32 cases of malignant ovarian cancer and 70 cases of benign ovarian tumor according to pathological diagnosis). TVS, color Doppler, and serum tumor markers were used for tumor diagnosis. The sensitivity, specifity, positive prediction, negative prediction, and Youden's index were analyzed. Of the 102 patients, 32 were diagnosed with malignant ovarian cancer and 70 were diagnosed with benign ovarian tumor according to pathological diagnosis. Based on TVS results, 37 cases were malignant while 65 cases were benign. Based on color Doppler results, 34 cases were malignant while 68 cases were benign. Based on TVS and color Doppler results, 35 cases were malignant while 65 were benign. Based on CA125 test results, 34 cases were malignant while 68 cases were benign. Based on CEA test results, 8 cases were malignant and 94 cases were benign. Bases on AFP test results, 9 cases were malignant while 93 cases were benign. Based on the results of combination tumor marker test, 38 cases were malignant while 64 cases were benign. The combination of TVS, color Doppler, and tumor marker test showed optimal diagnostic value with a sensitivity of 90.63 %, specificity of 97.14 %, positive prediction of 93.94 %, negative prediction of 98.55 %, and Youden's index of 94.02 %. The combination of TVS, color Doppler, and tumor marker test is of great diagnostic value, which should be widely used in clinical practice.

    Early brain injury (EBI) after aneurysmal subarachnoid hemorrhage (aSAH) is defined as brain injury occurring within 72 h of aneurysmal rupture. Although EBI is the most significant predictor of outcomes after aSAH, its underlying pathophysiology is not well understood. We hypothesize that EBI after aSAH is associated with an increase in peripheral inflammation measured by cytokine expression levels and changes in associations between cytokines. aSAH patients were enrolled into a prospective observational study and were assessed for markers of EBI: global cerebral edema (GCE), subarachnoid hemorrhage early brain edema score (SEBES), and Hunt-Hess grade. Serum samples collected at ≤ 48 h of admission were analyzed using multiplex bead-based assays to determine levels of 13 pro- and anti-inflammatory cytokines. Pairwise correlation coefficients between cytokines were represented as networks. Cytokine levels and differences in correlation networks were compared between EBI groups. Of the 71 patients enrolled in the study, 17 (24%) subjects had GCE, 31 (44%) subjects had SEBES ≥ 3, and 21 (29%) had HH ≥ 4. IL-6 was elevated in groups with GCE, SEBES ≥ 3, and HH ≥ 4. MIP1β was independently associated with high-grade SEBES. Correlation network analysis suggests higher systematic inflammation in subjects with SEBES ≥ 3. EBI after SAH is associated with increased levels of specific cytokines. Peripheral levels of IL-10, IL-6, and MIP1β may be important markers of EBI. Investigating systematic correlations in addition to expression levels of individual cytokines may offer deeper insight into the underlying mechanisms related to EBI.

    Full Text Available We aimed to evaluate the specificity of 12 tumor markers related to colon carcinoma and identify the most sensitive index. Logistic regression and Bhattacharyya distance were used to evaluate the index. Then, different index combinations were used to establish a support vector machine (SVM diagnosis model of malignant colon carcinoma. The accuracy of the model was checked. High accuracy was assumed to indicate the high specificity of the index. Through Logistic regression, three indexes, CEA, HSP60 and CA199, were screened out. Using Bhattacharyya distance, four indexes with the largest Bhattacharyya distance were screened out, including CEA, NSE, AFP, and CA724. The specificity of the combination of the above six indexes was higher than that of other combinations, so did the accuracy of the established SVM identification model. Using Logistic regression and Bhattacharyya distance for detection and establishing an SVM model based on different serum marker combinations can increase diagnostic accuracy, providing a theoretical basis for application of mathematical models in cancer diagnosis.

    A subclinical inflammation state was detected in the early step of diabetes, which increases the serum levels of cytokines that induce acute-phase protein synthesis as C-reactive protein (PCR) and fibrinogen (Fg), stimulating the endothelial disfunction of adhesion molecules. Thirty patients (15 boys, 15 girls) with type 1 diabetes (DT1), without vascular complications, were studied. Their mean age and duration of diabetes were 11.8 +/- 2.1 and 3.9 +/- 3.2 years, respectively. The laboratory parameters evaluated were: blood leukocytes count, globular sedimentation velocity, fasting glycemia, glycosylated hemoglobin (HbA1c), high sensitivity PCR (uPCR), plasma soluble E-selectin (sE-S), sVCAM-1 and microalbuminuria. Increased levels of uPCR, sE-S and VCAM-1 were found, compared with the control group control [0.60 (0.30-1.25) vs. 0.20 (0.20-0.65) mg/l, p = 0.013], [108 (60-150) vs. 68 (56-82) ng/ml, p = 0.0031] y [750 (708-826) vs. 721 (674-751) ng/ml, p = 0.039] respectively. When diabetic patients were grouped according to duration of disease (3 and > de 3 years), uPCR values were higher in the second group. uPCR levels were better correlated with sE-S (r = 0.44, p = 0.03) and VCAM-1 (r = 0.49, p = 0.02). These results suggest the presence of pro-inflammatory and endothelial activation states, which are strongly associated with DT1.

    2015-10-01

    Full Text Available Background: Recommendations have been made, following the multicenter Surviving Sepsis Campaign study, to standardize the definition of severe sepsis with reference to several parameters such as haemodynamic stability, acid-base balance, bilirubin, creatinine, International Normalized Ratio (INR, urine output and pulmonary functional value of the ratio between arterial oxigen partial pressure and inspiratory oxigen concentration. Procalcitonin (PCT is considered to be a gold standard biomarker for the inflammatory response, and recent studies have shown that it may help to discover whether a seriously ill person is developing sepsis. C-reactive protein (CRP is also used as a marker of inflammation in the body, as its blood levels increase if there is any inflammation in the body. The aim of this study was to evaluate serum procalcitonin and C-reactive protein levels as diagnostic and prognostic biomarkers of severe sepsis.

    Full Text Available Jorge E Toblli, Gabriel Cao, Margarita Angerosa Laboratory of Experimental Medicine, Hospital Alemán, School of Medicine, University of Buenos Aires, Buenos Aires, Argentina Background and aims: Iron deficiency is common in inflammatory bowel disease, yet oral iron therapy may worsen the disease symptoms and increase systemic and local oxidative stress. The aim of this study was to compare the effects of oral ferrous sulfate and iron polymaltose complex on inflammatory and oxidative stress markers in colitic rats.Methods: Animals were divided into four groups with ten animals each. Rats of three groups received dextran sodium sulfate to induce colitis and animals of two of these groups received 5 mg iron/kg of body weight a day, as ferrous sulfate or iron polymaltose complex, for 7 days. Gross colon anatomy, histology of colon and liver, stainings of L-ferritin, Prussian blue, hepcidin, tumor necrosis factor-α, and interleukin-6, as well serum levels of liver enzymes, inflammatory markers, and iron markers, were assessed.Results: Body weight, gross anatomy, crypt injury and inflammation scores, inflammatory parameters in liver and colon, as well as serum and liver hepcidin levels were not significantly different between colitic animals without iron treatment and colitic animals treated with iron polymaltose complex. In contrast, ferrous sulfate treatment caused significant worsening of these parameters. As opposed to ferrous sulfate, iron polymaltose complex caused less or no additional oxidative stress in the colon and liver compared to colitic animals without iron treatment.Conclusion: Iron polymaltose complex had negligible effects on colonic tissue erosion, local or systemic oxidative stress, and local or systemic inflammation, even at high therapeutic doses, and may thus represent a valuable oral treatment of iron deficiency in inflammatory bowel disease. Keywords: preclinical, oral iron treatment, tolerability, colonic tissue erosion

    Full Text Available BACKGROUND: Studies have shown that patients suffering from depression or schizophrenia often have immunological alterations that can be detected in the blood. Others reported a possible link between inflammation, a microgliosis and the blood-brain barrier (BBB in suicidal patients. Serum S100B is a marker of BBB function commonly used to study cerebrovascular wall function. METHODS: We measured levels of S100B in serum of 40 adolescents with acute psychosis, 24 adolescents with mood disorders and 20 healthy controls. Patients were diagnosed according to DSM-IV TR criteria. We evaluated suicidal ideation using the suicidality subscale of the Brief Psychiatric Rating Scale for Children (BPRS-C. RESULTS: Serum S100B levels were significantly higher (p<0.05 and correlated to severity of suicidal ideation in patients with psychosis or mood disorders, independent of psychiatric diagnosis. Patients with a BPRS-C suicidality subscores of 1-4 (low suicidality had mean serum S100B values +/- SEM of 0.152+/-0.020 ng/mL (n = 34 compared to those with BPRS-C suicidality subscores of 5-7 (high suicidality with a mean of 0.354+/-0.044 ng/mL (n = 30. This difference was statistically significant (p<0.05. CONCLUSION: Our data support the use of S100B as an adjunctive biomarker to assess suicidal risk in patients with mood disorders or schizophrenia.

    The tight junction regulator zonulin has attracted clinical attention as a biomarker of increased gastrointestinal permeability. Recent work also suggests zonulin to represent a general regulator of tissue barriers and a player in metabolic inflammation. Here, we investigated the associations of zonulin with chronic heart failure (CHF), kidney function, and metabolic inflammation. Using multiple linear regression (Generalized Linear Model), this study determined the association of plasma zonulin with different laboratory and clinical parameters in 225 patients carrying automatic implantable cardioverters/defibrillators (AICD) for primary or secondary prevention. In another 115 patients with diastolic or systolic CHF, we investigated a possible relationship between zonulin and CHF severity. In the AICD cohort, zonulin associated inversely with serum creatinine (p = 0.013), carboxymethyl-lysine calprotectin (p zonulin increased significantly with high-sensitivity CRP (p = 0.014). In the CHF cohort, we found a highly significant rise of NT-proBNP, but not of zonulin with NYHA functional classes I-IV or other parameters of CHF severity. The inverse associations of zonulin with creatinine and markers of cardio-vascular risk (high CMLcalprotectin and kynurenine, low homoarginine) are novel findings that need further experimental and clinical clarification. Our study indicates zonulin involvement in metabolic inflammation in T2D, but no association with disease status in CHF.

    In the study, gas chromatography/time-of-flight mass spectrometry (GC/TOFMS) techniques coupled with principal components analysis (PCA) were used to investigate metabolite perturbations in the serum of the rats exposed to 0.75, 3 or 8 Gy gamma rays. Male standard deviation rats were gamma-irradiated at doses of 0.75, 3 and 8 Gy (1.9 Gy min -1 ) or sham-irradiated. Serum samples were collected over the first 24 h under the exposure to irradiation in order to analyse the samples by GC/TOFMS. And multivariate data were analysed by PCA. The composition of metabolites in serum yielded distinct metabolomic phenotypes for 0.75, 3 and 8 Gy at 24 h after irradiation. Nine serum metabolites were significantly altered as a result of radiation exposure. Up-regulated metabolites included inositol, serine, lysine, glycine, threonine and glycerol; down regulated metabolites included isocitrate, gluconic acid and stearic acid. The nine metabolites were significantly altered after ionising radiation for they may be the potential bio-markers for the diagnosis of radiation injury. All rights reserved. (authors)

  12. Inflammation Thread Runs across Medical Laboratory Specialities

    2016-01-01

    Full Text Available We work on the assumption that four major specialities or sectors of medical laboratory assays, comprising clinical chemistry, haematology, immunology, and microbiology, embraced by genome sequencing techniques, are routinely in use. Medical laboratory markers for inflammation serve as model: they are allotted to most fields of medical lab assays including genomics. Incessant coding of assays aligns each of them in the long lists of big data. As exemplified with the complement gene family, containing C2, C3, C8A, C8B, CFH, CFI, and ITGB2, heritability patterns/risk factors associated with diseases with genetic glitch of complement components are unfolding. The C4 component serum levels depend on sufficient vitamin D whilst low vitamin D is inversely related to IgG1, IgA, and C3 linking vitamin sufficiency to innate immunity. Whole genome sequencing of microbial organisms may distinguish virulent from nonvirulent and antibiotic resistant from nonresistant varieties of the same species and thus can be listed in personal big data banks including microbiological pathology; the big data warehouse continues to grow.

    Patients with marker-positive central nervous system (CNS) germ cell tumors are typically monitored for tumor recurrence with both tumor markers (AFP and b-hCG) and MRI. We hypothesize that the recurrence of these tumors will always be accompanied by an elevation in tumor markers, and that surveillance MRI may not be necessary. We retrospectively identified 28 patients with CNS germ cell tumors treated at our institution that presented with an elevated serum or cerebrospinal fluid (CSF) tumor marker at the time of diagnosis. We then identified those who had a tumor recurrence after having been in remission and whether each recurrence was detected via MRI changes, elevated tumor markers, or both. Four patients suffered a tumor recurrence. Only one patient had simultaneously elevated tumor markers and MRI evidence of recurrence. Two patients had evidence of recurrence on MRI without corresponding elevations in serum or CSF tumor markers. One patient had abnormal tumor markers with no evidence of recurrence on MRI until 6 months later. We conclude that in patients with marker-positive CNS germ cell tumors who achieve complete remission, continued surveillance imaging in addition to measurement of tumor markers is indicated to detect recurrences.

    Twenty to thirty percent of testicular cancer (TC) survivors have elevated serum levels of luteinising hormone (LH) with or without corresponding low testosterone levels (Leydig cell dysfunction) during clinical follow-up for TC. However, it remains to be clarified if this subgroup of TC survivors has an increased long-term risk of systemic inflammation and metabolic syndrome (MetS) when compared with TC survivors with normal Leydig cell function during follow-up. TC survivors with Leydig cell dysfunction and a control group of TC survivors with normal Leydig cell function during follow-up were eligible for participation in the study. Markers of systemic inflammation and prevalence of MetS were compared between TC survivors with Leydig cell dysfunction and the control group. Of 158 included TC survivors, 28 (18%) had uncompensated Leydig cell dysfunction, 59 (37%) had compensated Leydig cell dysfunction and 71 (45%) had normal Leydig cell function during follow-up. MetS and markers of systemic inflammation were evaluated at a median follow-up of 9.7 years (interquartile range 4.1-17.1) after TC treatment. The prevalence of MetS was significantly lower among patients with compensated Leydig cell dysfunction during follow-up (12% versus 27%, p = 0.04), whereas there was no difference between TC survivors with uncompensated Leydig cell dysfunction and controls (33% versus 27%, p = 0.5). Apart from high-sensitivity C-reactive protein which was higher in TC survivors with uncompensated Leydig cell dysfunction during follow-up, there was no evidence of increased systemic inflammation in patients with Leydig cell dysfunction during clinical follow-up. Total testosterone at follow-up was significantly associated with MetS, whereas there was no association between LH and MetS. We did not find evidence that TC survivors with Leydig cell dysfunction during clinical follow-up had increased long-term risk of MetS. Total testosterone at follow-up was significantly associated

    To investigate the association between serum ferritin levels and glaucoma in a South Korean population. This retrospective cross-sectional study included 164 029 subjects who underwent screening at Kangbuk Samsung Hospital Health Screening Center between August 2012 and July 2013. All subjects underwent a physical examination, answered sociodemographic and behavioural questions, and provided samples for laboratory analyses. A digital fundus photograph of both eyes was taken, and all photographs were reviewed by ophthalmologists. The ophthalmologists determined if an eye had glaucoma based on criteria set forth by the International Society of Geographical and Epidemiological Ophthalmology and the appearance of the retinal nerve fibre layer and optic disc. The mean serum ferritin level was 56.98 ng/mL in women and 223.82 ng/mL in men. After adjusting for age, serum iron, total iron-binding capacity (TIBC), transferrin saturation, white blood cell (WBC) count, high-sensitivity C-reactive protein (HsCRP) and total vitamin D level, males in the highest quartile for serum ferritin level had a higher OR for glaucoma than males in the lowest quartile (OR=1.176, 95% CI 1.030 to 1.342, p=0.016); we did not observe this relationship among women. Other markers of iron metabolism, such as iron level, transferrin saturation and TIBC, and inflammation measures, including WBC, HsCRP and total vitamin D, were not associated with glaucoma. High serum ferritin level was associated with a high risk of glaucoma in men, but not in women. Because serum ferritin is related to oxidative stress and inflammation, it might play a role in glaucoma development. Published by the BMJ Publishing Group Limited.

    Obesity is characterized by an increased production of inflammatory markers. High levels of circulating free fatty acids and chronic inflammation lead to increased oxidative stress, contributing to the development of insulin resistance (IR). Recent studies have focused on the potential use of flavonoids for obesity management due to their antioxidant and anti-inflammatory properties. This study was designed to investigate the antioxidant and anti-inflammatory effects of helichrysum and grapefruit extracts in overweight insulin-resistant rats. Thirty-eight male Wistar rats were randomly distributed in two groups: control group (n=8) and high-fat sucrose (HFS) group (n=30). After 22 days of ad libitum water and food access, the rats fed HFS diet changed to standard diet and were reassigned into three groups (n=10 each group): nonsupplemented, helichrysum extract (2 g/kg bw), and grapefruit extract (1 g/kg bw) administered for 5 weeks. Rats supplemented with both extracts gained less body weight during the 5-week period of treatment, showed lower serum insulin levels and liver TBARS levels. Leptin/adiponectin ratio, as an indicator of IR, was lower in both extract-administered groups. These results were accompanied by a reduction in TNFα gene expression in epididymal adipose tissue and intestinal mucosa, and TLR2 expression in intestinal mucosa. Helichrysum and grapefruit extracts might be used as complement hypocaloric diets in weight loss treatment. Both extracts helped to reduce weight gain, hyperinsulinemia, and IR, improved inflammation markers, and decreased the HFS diet-induced oxidative stress in insulin-resistant rats.

    The effect of radioiodine ( 131I ) in Graves disease (GD) is probably due to the direct physical destruction of thyrocytes by beta radiation, and by the indirect action through stimulation of apoptosis in these cells. The aim of our study was to investigate the changes in serum concentrations of sFas and sFasL as stimulators of apoptosis, and Bcl-2 as an inhibitor of apoptosis in patients with GD following 131I administration. The study was performed on 30 patients with GD (29 female and 1 male aged 25-45). All patients were euthyroid (biochemical and clinical) prior to radioiodine therapy. The target absorbed dose ranged between 90 and 160 Gy. We assessed markers of apoptosis and hormone concentrations (fT3, fT4 and TSH) in the following manner: before 131I administration, then two weeks, one month, two, three, four, and five months after 131I administration. After four months, the concentrations of sFas and sFasL rose by 50% and decreased during the next month. Pretherapeutic concentrations of Bcl-2 were elevated, and peaked two weeks after ingestion, showing a gradual decrease with time. We found a significant increase in serum TSH, and a decrease of fT3 and fT4 concentrations by the end of the third month of radioiodine therapy. Decreases in serum levels of sFas and sFasL and increases of Bcl-2 are regarded as characteristic for GD patients before radioiodine therapy. Radioiodine therapy reverses the ratio of estimated markers after four months. The concentrations of hormones reflect actual thyroid function, whereas concentrations of markers of apoptosis may suggest morphological changes. (author)

    The pathogenesis of cardiovascular complications in obstructive sleep apnea syndrome (OSAS) is not fully understood but is likely multifactorial in origin. Inflammatory processes play an important role in the pathogenesis of atherosclerosis, and circulating levels of several markers of inflammation have been associated with future cardiovascular risk. These include cell adhesion molecules such as intercellular adhesion molecule-1 and selectins, cytokines such as tumour necrosis factor alpha and interleukin 6, chemokines such as interleukin 8, and C-reactive protein. There is also increasing evidence that inflammatory processes play an important role in the cardiovascular pathophysiology of OSAS and many of the inflammatory markers associated with cardiovascular risk have been reported as elevated in patients with OSAS. Furthermore, animal and cell culture studies have demonstrated preferential activation of inflammatory pathways by intermittent hypoxia, which is an integral feature of OSAS. The precise role of inflammation in the development of cardiovascular disease in OSAS requires further study, particularly the relationship with oxidative stress, metabolic dysfunction, and obesity.

    Inflammation, endothelial dysfunction, and mineral bone disease are critical factors contributing to morbidity and mortality in hemodialysis (HD) patients. Physical exercise alleviates inflammation and increases bone density. Here, we investigated the effects of intradialytic aerobic cycling exercise on HD patients. Forty end-stage renal disease patients undergoing HD were randomly assigned to either an exercise or control group. The patients in the exercise group performed a cycling program consisting of a 5-minute warm-up, 20 minutes of cycling at the desired workload, and a 5-minute cool down during 3 HD sessions per week for 3 months. Biochemical markers, inflammatory cytokines, nutritional status, the serum endothelial progenitor cell (EPC) count, bone mineral density, and functional capacity were analyzed. After 3 months of exercise, the patients in the exercise group showed significant improvements in serum albumin levels, the body mass index, inflammatory cytokine levels, and the number of cells positive for CD133, CD34, and kinase insert domain-conjugating receptor. Compared with the exercise group, the patients in the control group showed a loss of bone density at the femoral neck and no increases in EPCs. The patients in the exercise group also had a significantly greater 6-minute walk distance after completing the exercise program. Furthermore, the number of EPCs significantly correlated with the 6-minute walk distance both before and after the 3-month program. Intradialytic aerobic cycling exercise programs can effectively alleviate inflammation and improve nutrition, bone mineral density, and exercise tolerance in HD patients.

    Full Text Available Fetuin-A is a calcification inhibitor, negative acute phase response marker and cardiovascular mortality predictor in hemodialysis patients. Low levels of fetuin-A are associated with malnutrition, inflammation, decreased bone mass density, low-turnover bone and use of high calcium concentration dialysate. Hemodialysis procedure (HD has been shown to decrease fetuin-A levels by 20%, probably due to HD-induced inflammation or acute changes in calcium metabolism. The aim of our study was to investigate effects of HD on serum fetuin-A levels. Forty clinically and hemodynamically stable hemodialysis patients (21 females, 68 (38-85 years underwent routine bicarbonate hemodialysis or hemodiafiltration with polysulfone dialyzer. On consecutive HD dialysis solution with different calcium concentration with/without citric acid was used to assess influence of calcium shifts and parathyroid activity on fetuin-A changes during HD. All other parameters of HD were kept constant. Serum fetuin-A, calcium, phosphorus, iPTH, CRP and other biochemical parameters were measured before and after each HD. Our data show that predialysis serum fetuin-A levels have positive correlation with iPTH levels (p<0.05 and tendency to decrease with higher CRP levels. There was no change in fetuin-A levels during HD: 206 (167.1; 231.9 ug/ml before and 208.9 (170.3; 246.3 ug/ml after HD; respectively. When corrected for haemoconcentration, decrease in fetuin-A was only 2.8% (p<0.05. There was also no difference between effect of hemodialysis and hemodia-filtration procedure. The use of different calcium dialysate concentrations had distinct effect on iPTH levels during and after HD, however, we observed no associated changes in fetuin-A levels. The use of dialysate solution with citric acid had no effect on fetuin-A levels. In conclusion, standard bicarbonate HD with polysulfone dialyser and ultrapure dialysate induces only minor changes in fetuin-A and no changes in hsCRP levels

Optimization of perio-perative analgesia method, then reduce perioperative stress response, reduce opioiddosage, to reduce or even avoid systemic adverse reactions and elevated levels of tumor markers. Serum levels of tumor markers in patients with lung cancer are closely related to tumor growth. Clinical research reports on regional anesthesia effect on tumor markers for lung cancer are still very little in domesticliterature. The aim of this study is to evaluate the effects of thoracic paraverte-bral block on postoperative analgesia and serum level of tumor marker in lung cancer patients undergoing video-assisted thoracoscopic surgery. Methods Lung cancer patients undergoing video-assisted thoracoscopic surgery were randomly divided into 2 groups (n=20 in each group. The patients in group G were given only general anesthesia. The thoracic paravertebral blockade (PVB was performed before general anesthesia in patients of group GP. The effect of PVB was judged by testing area of block. Patient controlled intravenous analgesia (PCIA pump started before the end of surgery in 2 groups. Visual analogue scale (VAS score was recorded after extubation 2 h (T1, 24 h (T2 and 48 h (T3 after surgery and the times of PCIA and the volume of analgesic drugs used were recorded during 48 h after surgery.

    Full Text Available Apolipoproteins are very heterogeneous protein family, implicated in plasma lipoprotein structural stabilization, lipid metabolism, inflammation, or immunity. Obtaining detailed information on apolipoprotein composition and structure may contribute to elucidating lipoprotein roles in atherogenesis and to developing new therapeutic strategies for the treatment of lipoprotein-associated disorders. This study aimed at developing a comprehensive method for characterizing the apolipoprotein component of plasma VLDL, LDL, and HDL fractions from patients undergoing carotid endarterectomy, by means of two-dimensional electrophoresis (2-DE coupled with Mass Spectrometry analysis, useful for identifying potential markers of plaque presence and vulnerability. The adopted method allowed obtaining reproducible 2-DE maps of exchangeable apolipoproteins from VLDL, LDL, and HDL. Twenty-three protein isoforms were identified by peptide mass fingerprinting analysis. Differential proteomic analysis allowed for identifying increased levels of acute-phase serum amyloid A protein (AP SAA in all lipoprotein fractions, especially in LDL from atherosclerotic patients. Results have been confirmed by western blotting analysis on each lipoprotein fraction using apo AI levels for data normalization. The higher levels of AP SAA found in patients suggest a role of LDL as AP SAA carrier into the subendothelial space of artery wall, where AP SAA accumulates and may exert noxious effects.

    There is evidence that immune system dysregulation and inflammation may play a role in the development of post-traumatic stress disorder (PTSD). Previous studies have reported elevated levels of inflammatory markers such as C-reactive protein (CRP) in individuals with PTSD. However, it is unclear whether exacerbation of PTSD symptoms late in life is also associated with elevated inflammation. The purpose of this pilot study was to examine the relationship between inflammation and late-life PTSD. We recruited veterans either diagnosed with PTSD after the age of 55 or with no diagnosis of PTSD. Six veterans did not meet all eligibility criteria, including five who did not meet criteria for PTSD and one with celiac disease. The final sample included a total of 32 male veterans (16 veterans diagnosed with PTSD after 55 and 16 veterans without PTSD). The groups were matched as closely as possible on age, body mass index, and combat exposure. PTSD symptoms were assessed using the Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and depressive symptoms were assessed using the Hamilton Rating Scale for Depression. Inflammation was measured using serum CRP level. The two groups did not differ on sample characteristics including age, body mass index, tobacco use, medication use, and military history. CRP level was found to be significantly higher in the PTSD group than in the comparison group (Z = -3.047, p = 0.002), which was also observed after adjusting for depression scores (F(1, 27) = 8.30, p = 0.0077). The results from this pilot study suggest that late-life PTSD may be associated with increased inflammation. Further research in larger samples is needed to corroborate these findings and to clarify the relationship between inflammation and PTSD, which may lead to improved methods of diagnosis and treatment.

    Recent evidence suggests that low vitamin D concentrations are associated with increased levels of inflammatory markers. However, there are limited studies investigating associations between vitamin D levels and inflammatory markers in the general population and much of this evidence in older adults is inconclusive. Therefore, this study investigates the cross-sectional association of serum 25-hydroxyvitamin D (25(OH)D) levels with inflammatory markers in 5870 older English adults from wave 6 (2012-2013) of the English Longitudinal Study of Ageing (ELSA). ELSA is a large prospective observational study of community-dwelling people aged 50 years and over in England. Serum 25(OH)D levels, C-reactive protein (CRP) levels, plasma fibrinogen levels, white blood cell count (WBC), age, season of blood collection, waist circumference, total non-pension household wealth, measures of health and health behaviours that included depression, number of cardiovascular, non-cardiovascular conditions and difficulties in activities of daily living, smoking, and physical activity were measured. There was a significant negative association between low 25(OH)D levels (≤30 nmol/l) and CRP (OR 1·23, 95 % CI 1·00, 1·51) and WBC (OR 1·35, 95 % CI 1·13, 1·60) that remained after adjustment for a wide range of covariates of clinical significance. However, for fibrinogen, the association did not remain significant when waist circumference was entered in the final model. Our findings showed that 25(OH)D levels were associated with two out the three inflammatory markers investigated. The independent and inverse association between serum 25(OH)D levels and inflammation suggests a potential anti-inflammatory role for vitamin D in older English individuals from the general population.

    Blood-based protein biomarkers have recently shown as simpler diagnostic modalities for colorectal cancer, while their association with clinical pathological characteristics is largely unknown. In this study, we not only examined the sensitivity and reliability of single/multiple serum markers for diagnosis, but also assessed their connection with pathological parameters from a total of 279 colorectal cancer patients. Our study shown that glycoprotein carcinoembryonic antigen (CEA) owns the highest sensitivity among single marker in the order of CEA > cancer antigen 72-4 (CA72-4) > cancer antigen 19-9 9 (CA19-9) > ferritin > cancer antigen 125 (CA125), while the most sensitive combined-markers for two to five were: CEA + CA72-4; CEA + CA72-4 + CA125; CEA + CA19-9 + CA72-4 + CA125; and CEA + CA19-9 + CA72-4 + CA125 + ferritin, respectively. We also demonstrated that patients who had positive preoperative serum CEA, CA19-9, or CA72-4 were more likely with lymph node invasion, positive CA125 were prone to have vascular invasion, and positive CEA or CA125 were correlated with perineural invasion. In addition, positive CA19-9, CA72-4, or CA125 was associated with poorly differentiated tumor, while CEA, CA19-9, CA72-4, CA125 levels were positively correlated with pathological tumor-node-metastasis stages. We here conclude that combined serum markers can be used to not only diagnose colorectal cancer, but also appraise the tumor status for guiding treatment, evaluation of curative effect, and prognosis of patients.

    Full Text Available To evaluate maternal serum C-reactive protein (CRP concentrations in pregnancies complicated by preterm prelabor rupture of membranes (PPROM in relation to the presence of microbial invasion of the amniotic cavity (MIAC and/or intra-amniotic inflammation (IAI.Two hundred and eighty-seven women with singleton pregnancies complicated by PPROM between 2014 and 2016 were included in this study. Maternal blood and amniotic fluid samples were collected at the time of admission. Maternal serum CRP concentration was measured using a high-sensitivity immunoturbidimetric assay. Interleukin-6 (IL-6 concentration was measured using a point-of-care test. MIAC was diagnosed based on a positive polymerase chain reaction result for Ureaplasma species, Mycoplasma hominis, and/or Chlamydia trachomatis and for the 16S rRNA gene. IAI was characterized by an amniotic fluid IL-6 concentration of ≥ 745 pg/mL.Women with MIAC and IAI had higher maternal serum CRP concentrations than did women without (with MIAC: median 6.9 mg/L vs. without MIAC: median 4.9 mg/L; p = 0.02; with IAI: median 8.6 mg/L vs. without IAI: median 4.7 mg/L; p < 0.0001. When women were split into four subgroups based on the presence of MIAC and/or IAI, women with the presence of both MIAC and IAI had higher maternal serum CRP than did women with IAI alone, with MIAC alone, and women without MIAC and IAI (both MIAC and IAI: median: 13.1 mg/L; IAI alone: 6.0 mg/L; MIAC alone: 3.9 mg/L; and without MIAC and IAI: median 4.8 mg/L; p < 0.0001. The maternal serum CRP cutoff value of 17.5 mg/L was the best level to identify the presence of both MIAC and IAI, with sensitivity of 47%, specificity of 96%, positive predictive value of 42%, negative predictive value of 96%, and the positive likelihood ratio of 10.9.The presence of both MIAC and IAI was associated with the highest maternal serum CRP concentrations.

    The systemic (extrapulmonary) effects and comorbidities of chronic obstructive pulmonary disease (COPD) contribute substantially to its burden. The supposed link between COPD and its systemic effects on distal organs could be due to the low-grade systemic inflammation. The aim of this study was to investigate whether the systemic inflammation may influence the skin condition in COPD patients. Forty patients with confirmed diagnosis of COPD and a control group consisting of 30 healthy smokers and 20 healthy never-smokers were studied. Transepidermal water loss, stratum corneum hydration, skin sebum content, melanin index, erythema index, and skin temperature were measured with worldwide-acknowledged biophysical measuring methods at the volar forearm of all participants using a multifunctional skin physiology monitor. Biomarkers of systemic inflammation, including high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α), were measured in serum using commercially available enzyme-linked immunosorbent assays. There were significant differences between COPD patients and healthy never-smokers in skin temperature, melanin index, sebum content, and hydration level ( P skin measured. The mean levels of hsCRP and IL-6 in serum were significantly higher in COPD patients and healthy smokers in comparison with healthy never-smokers. There were significant correlations between skin temperature and serum hsCRP ( R =0.40; P =0.02) as well as skin temperature and serum IL-6 ( R =0.49; P =0.005) in smokers. Stratum corneum hydration correlated significantly with serum TNF-α ( R =0.37; P =0.01) in COPD patients. Differences noted in several skin biophysical properties and biomarkers of systemic inflammation between COPD patients, smokers, and healthy never-smokers may suggest a possible link between smoking-driven, low-grade systemic inflammation, and the overall skin condition.

    Full Text Available Abstract Sleep deprivation has been shown to increase inflammatory markers in rat sera and peripheral blood mononuclear cells. Inflammation is a condition associated with pathologies such as obesity, cancer, and cardiovascular diseases. We investigated changes in the pro and anti-inflammatory cytokines and adipokines in different depots of white adipose tissue in rats. We also assessed lipid profiles and serum levels of corticosterone, leptin, and adiponectin after 96 hours of sleep deprivation. Methods The study consisted of two groups: a control (C group and a paradoxical sleep deprivation by 96 h (PSD group. Ten rats were randomly assigned to either the control group (C or the PSD. Mesenteric (MEAT and retroperitoneal (RPAT adipose tissue, liver and serum were collected following completion of the PSD protocol. Levels of interleukin (IL-6, interleukin (IL-10 and tumour necrosis factor (TNF-α were analysed in MEAT and RPAT, and leptin, adiponectin, glucose, corticosterone and lipid profile levels were analysed in serum. Results IL-6 levels were elevated in RPAT but remained unchanged in MEAT after PSD. IL-10 protein concentration was not altered in either depot, and TNF-α levels decreased in MEAT. Glucose, triglycerides (TG, VLDL and leptin decreased in serum after 96 hours of PSD; adiponectin was not altered and corticosterone was increased. Conclusion PSD decreased fat mass and may modulate the cytokine content in different depots of adipose tissue. The inflammatory response was diminished in both depots of adipose tissue, with increased IL-6 levels in RPAT and decreased TNF-α protein concentrations in MEAT and increased levels of corticosterone in serum.

    We evaluated recently introduced automated immunoassay analyzer LUMIPULSE G1200 (Fujirebio, Inc., Tokyo, Japan) for detecting serologic hepatitis B virus (HBV) markers by comparison with the results by ARCHITECT i4000SR (Abbott, Abbott Park, IL). Precision performance was evaluated over 20 days. HBV surface antigen (HBsAg), HBV e antigen (HBeAg), antibodies to HBV core antigen (anti-HBc), antibodies to HBeAg (anti-HBe), and antibodies to HBsAg (anti-HBs) in a total of 1,000 serum samples were assessed by the two analyzers. Discrepant results were retested by COBAS e411 (Roche Diagnostics, Mannheim, Germany). LUMIPULSE showed excellent precision performance of total imprecision less than 3.5% coefficient of variation. The qualitative results between the two analyzers were agreed with each other in 92.0-99.8% of the specimens according to the different HBV markers. The degrees of reactions for HBeAg were moderately correlated between the two analyzers (r = 0.60), and those of other HBV markers were well correlated (r = 0.80 or greater). However, there were 183 discrepancies among 1,000 cases, and most of them showed degree of reaction around the cutoff values. LUMIPULSE G1200 showed well-concordant results with ARCITHECT for hepatitis B serologic tests. However, results near the cutoff values would need to be retested with other immunoassay or molecular methods, when the serological profiles of HBV markers are unusual or are not correlated to the clinical conditions of the patient, due to discrepancies between the immunoassay analyzers. © 2013 Wiley Periodicals, Inc.

    To evaluate the expression of serum fibrosis markers in liver transplantation (LT) recipients on everolimus monotherapy compared to patients on an anti-calcineurin regimen. This cross-sectional case-control study included LT patients on everolimus monotherapy (cases) (E) (n = 30) and matched controls on an anti-calcineurin regimen (calcineurin inhibitors, CNI), paired by etiology of liver disease and time since LT (n = 30). Clinical characteristics, blood tests and elastography were collected. Serum levels of transforming growth factor-β (TGF-β), angiopoietin-1, tumor necrosis factor (TNF), platelet derived growth factor, amino-terminal propeptide of type III procollagen (PIIINP), hyaluronic acid (HA), VCM-1 (ng/mL), interleukin (IL)-10, interferon-inducible protein 10 (IP-10), vascular endothelial growth factor and hepatocyte growth factor (HGF) (pg/mL) were determined by enzyme-linked immunosorbent assay. Expression of these markers between E and CNI was compared. Stratified analysis was done according to factors that may influence liver fibrosis. Variables are described with medians (interquartillic range) or percentages. A total of 60 patients [age: 59 (49-64), hepatitis C virus (HCV): n = 21 (35%), time from LT: 73 mo (16-105)] were included. Patients had been on everolimus for a median of 15 mo. No differences in inflammatory activity, APRI test or liver elastography were found between the groups. No significant differences were observed between the groups in serum levels of PIIINP, metalloproteinase type = 1, angiopoietin, HGF, IP-10, TNF-α, IL-10 and vascular cell adhesion molecule. Patients on E had a lower expression of TGF-β [E: 12.7 (3.7-133.6), CNI: 152.5 (14.4-333.2), P = 0.009] and HA [E: 702.89 (329.4-838.2), CNI: 1513.6 (691.9-1951.4), P = 0.001] than those on CNI. This difference was maintained in the stratified analysis when recipient age is more than 50 years (TFG-β1: P = 0.06; HA: P = 0.005), in patients without active neoplasia (TFG-β1

    One direction of research in pathogenesis of multiple sclerosis (MS) has been to identify immunological markers associated with disease activity that are capable of predicting subsequent course of disease and are sensitive to intervention by immunomodulatory therapies. Adhesion molecules and tumor necrosis factor-α of the cytokine superfamily are associated with inflammation-mediated blood-brain barrier dysfunction and demyelination in the central nervous system (CNS). This study investigates the relationship between the serum level of soluble vascular adhesion molecule-1 (sVCAM), soluble intercellular adhesion molecule-1 (alCAM), tumor necrosis factor-α (TNF-α) and magnetic resonance imaging (MRI) activity in 18 patients with relapsing-remitting (RR) MS with different clinical activity. Patients with active gadolinium (Gd)-enhanced lesions on MRI showed a higher serum level of TNF-α, sVCA-1, slCAM-1 than RR MS patients without Gd-enhanced lesions. Control individuals (n=10) without MRI abnormalities had significantly lower serum levels of the above immunological parameters. These results suggest that serum levels of TNF-α and adhesion molecules slCAM-1 in RR MS patients are correlated with Gd-enhanced MRI and disease clinical activity and that they can be used as biological markers of disease activity. The soluble form of VCAM levels in peripheral blood did not correlate with disease activity and Gd-enhanced lesions of MRI. sVCAM as an early indicator of blood-brain barrier dysfunction may also serve as marker of beneficial activity in the relapsing phase of MS course.

    Psoriasis is a chronic inflammatory skin disease that is accompanied by metabolic disturbances and cardio-metabolic disorders. Fatty acids (FAs) might be a link between psoriasis and its comorbidity. The aim of the study was to evaluate serum concentrations of FAs and to investigate their association with the disease activity, markers of inflammation and possible involvement in psoriatic comorbidity: obesity, type 2 diabetes and hypertension. We measured 14 total serum fatty acids content and composition by gas-liquid chromatography and flame-ionization detector after direct in situ transesterification in 85 patients with exacerbated plaque psoriasis and in 32 healthy controls. FAs were grouped according to their biologic properties to saturated FA (SFA), unsaturated FA (UFA), monounsaturated FA (MUFA), n-3 polyunsaturated FA (n-3 PUFA) and n-6 PUFA. Generally, patients characteristic included: Psoriasis Area and Severity Index (PASI), Body Mass Index, inflammatory and biochemical markers, lipid profile and presence of psoriatic comorbidity. We have observed highly abnormal FAs pattern in psoriatic patients both with and without obesity compared to the control group. We have demonstrated association of PASI with low levels of circulating DHA, n-3 PUFA (p = 0.044 and p = 0.048, respectively) and high percent of MUFA (p = 0.024) in the non-obese psoriatic group. The SFA/UFA ratio increased with the duration of the disease (p = 0.03) in all psoriatic patients. These findings indicate abnormal FAs profile in psoriasis which may reflect metabolic disturbances and might play a role in the psoriatic comorbidity.

    Prenatal and postnatal smoke exposures are associated with many lung diseases in children due to impaired lung function, increased inflammation, and oxidative stress. We aimed to determine the influence of secondhand tobacco smoke exposure on the levels of nasal glutathione, IL-8, IL-17, MMP-9, and TIMP-1, as well as serum surfactant protein-D (SP-D) in wheezy children. We enrolled 150 children with recurrent wheezing and recorded wheezing characteristics at enrollment. We measured the levels of serum cotinine, SP-D, nasal glutathione, IL-8, IL-17, MMP-9, and TIMP-1. Serum cotinine levels between 3 and 12 ng/mL, and above 12 ng/mL were defined as lower and higher level secondhand tobacco smoke exposure, respectively. The ANOVA test, Pearson's correlation analysis and multivariate analysis with a linear regression test were used for the statistical analysis. Ninety-one children had been exposed to lower level secondhand tobacco smoke, while 24 children were exposed to higher level secondhand tobacco smoke. Thirty-five children were not exposed to cigarette smoke. Wheezing symptom scores were higher in exposed children (p = 0.03). Levels of other biomarkers showed no significant difference. Secondhand tobacco smoke exposure is associated with more severe respiratory symptoms in wheezing children. However, levels of nasal or serum inflammatory markers fail to explain this association, either because of different mechanical factors in the process or due to low levels of the biomarkers especially in nasal secretions.

    Full Text Available Introduction : Localized scleroderma is an autoimmune disease primarily affecting the skin. The cause of disease remains unexplained although environmental factors are implicated, which are likely to be responsible for activation of the endothelium and subsequent inflammation leading to excessive synthesis of collagen and extracellular matrix components. Aim: To determine concentrations of interleukin (IL-27, transforming growth factor (TGF-β1, TGF-β2, IL-6, and sIL-6R in patients with localized scleroderma compared to controls and to assess the relations between their levels and laboratory markers. Material and methods: The study encompassed 17 females with localized scleroderma (aged 25–67. The control group consisted of 30 age-matched healthy women. The blood was sampled from the basilic vein. Serum levels of cytokines were determined using ELISA. Results : The TGF-β2 levels were found to be significantly lower in patients with localized scleroderma compared to controls. Concentrations of TGF-β1 were decreased in scleroderma patients when compared to controls but without statistical significance. There were no significant differences in serum IL-6, sIL-6R and IL-27 levels between patients and the control group; however, we found a significant positive correlation between the level of sIL-6 and ESR among subjects with localized scleroderma. Conclusions : The findings of decreased serum levels of TGF-β1 and TGF-β2 in patients with localized scleroderma demonstrate a possible association of these cytokines with pathogenesis of the disease. The results suggest also that sIL-6R is likely to be involved in inflammation in patients with localized scleroderma.

    To date, there is a trend that the chemiluminescent microparticle immunoassays (CMIA) and electrochemiluminescence immunoassays (ECIA) technology gradually replacing the enzyme-linked immunosorbent assay (ELISA). But the performance such as the limit of quantitation (LOQ), precision, linear range of CMIA, or ECIA for serum markers of infectious diseases has rarely been reported. Using proficiency testing samples and standard materials, we confirmed the LOQ of the ELISA and the precision, linear range, LOQ, and instrument biases of the Abbott i2000 for eight serum markers. We used the Abbott i2000 and ELISAs to assess five HIV samples; the researchers were blinded to the true status of the samples. For the Abbott i2000, the coefficients of variation (CV) for the low, medium, and high concentration samples ranged from 1.06 to 12.74%, which were less than the allowable error; the linear ranges of HBsAg and HBsAb were 0.66-304.11 IU/ml and 8.16-1205.9 mIU/ml, respectively. For the Abbott i2000, the LOQs of HBsAg, HBsAb, HBeAg, HBeAb, HBcAb, anti-HCV, anti-TP, and anti-HIV were 0.026 IU/ml, 4 mIU/ml, 0.14 NCU/ml, 0.56 NCU/ml, 0.99 NCU/ml, 0.5 NCU/ml, 8.8 mIU/ml, and 1.92 NCU/ml, respectively, and these values were 0.16 IU/ml, 6.97 mIU/ml, 1.16 NCU/ml, 1.63 NCU/ml, 1.79 NCU/ml, 1.03 NCU/ml, 8.33 mIU/ml, and 1.3 NCU/ml, respectively, for the ELISA. When five HIV samples were blindly assessed, two cases were missed by the Abbott i2000 and the ELISA results were consistent with the expected results. The Abbott i2000 performed significantly better than the ELISA on HBV and HCV screening; however, for anti-TP and anti-HIV, the ELISA remained the preferred method. © 2016 Wiley Periodicals, Inc.

    Obesity in pregnancy is increasing and is a risk factor for metabolic pathology such as preeclampsia. In the nonpregnant, obesity is associated with dyslipidemia, vascular dysfunction, and low-grade chronic inflammation. Our aim was to measure microvascular endothelial function in lean and obese pregnant women at intervals throughout their pregnancies and at 4 months after delivery. Plasma markers of endothelial function, inflammation, and placental function and their association with microvascular function were also assessed. Women in the 1st trimester of pregnancy were recruited, 30 with a body mass index (BMI) less than 30 kg/m(2) and 30 with a BMI more than or equal to 30 kg/m(2) matched for age, parity, and smoking status. In vivo endothelial-dependent and -independent microvascular function was measured using laser Doppler imaging in the 1st, 2nd, and 3rd trimesters of pregnancy and at 4 months postnatal. Plasma markers of endothelial activation [soluble intercellular cell adhesion molecule-1 (sVCAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), von Willebrand factor (vWF), and plasminogen activator inhibitor (PAI)-1], inflammation (IL-6, TNFalpha, C-reactive protein, and IL-10), and placental function (PAI-1/PAI-2 ratio) were also assessed at each time point. The pattern of improving endothelial function during pregnancy was the same for lean and obese, but endothelial-dependent vasodilation was significantly lower (P lean women but declined to near 1st trimester levels in the obese (lean/obese difference, 115%; P lean response being greater than obese (P = 0.021), and response declined in both groups in the postpartum period. In multivariate analysis, time of sampling had the most impact on endothelial-independent function [18.5% (adjusted sum of squares expressed as a percentage of total means squared), P lean 0.30 (0.21-0.47), P lean counterparts. There was a higher PAI-1/ PAI-2 ratio in the 1st trimester in obese women, which improved later in

    Glasgow Prognostic Score (GPS) has been reported as a powerful prognostic tool for patients with advanced non-small cell lung cancer (NSCLC). The aim of this study was to assess the relationship between GPS and prognosis related tumor markers in patients with advanced NSCLC. We included 138 advanced NSCLC patients and twenty healthy controls in the study. GPS was calculated by combined serum C-reactive protein (CRP) and albumin. Three serum tumor markers, which included cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), carcinoembryonic antigen (CEA) and tissue polypeptide specific antigen (TPS), were detected by enzyme-linked immunosorbent assay (ELISA). GPS and tumor markers were all assessed before chemotherapy. All patients received at least 2 courses of cisplatin-based chemotherapy. After that, 2 to 5 years follow-up was conducted. Median levels of CYFRA21-1 were 1.5 ng/ml (0.1-3.1 ng/ml) in healthy controls, and 4.6 ng/ml (0.7-35.2 ng/ml) in GPS 0 advanced NSCLC, 11.2 ng/ml (0.4-89.2) ng/ml in GPS 1 advanced NSCLC, and 15.7 ng/ml (2.9-134.6 ng/ml) in GPS 2 advanced NSCLC, respectively. Median levels of CYFRA21-1 were higher in NSCLC patients than in healthy controls, and CYFRA21-1 increased gradually according to GPS category in NSCLC patients (PGPS, CEA and GPS, TPS and GPS. The Spearman's rank correlation coefficient were 0.67 (P GPS was an independent prognostic factor for advanced NSCLC. CYFRA21-1(>3.3 ng/ml) and TPS (>80 U/l) were related with the prognosis of advanced NSCLC by univariate analyses, but multivariate analyses showed CYFRA21-1, TPS and CEA were not the independent prognostic factors for advanced NSCLC. Our results showed GPS were positive correlated with CYFRA21-1, CEA and TPS in patients with advanced NSCLC. However, GPS was more efficient in predicting prognosis of advanced NSCLC than these three single prognosis related tumor markers.

    Full Text Available Polycystic ovary syndrome (PCOS represents the most common cause of anovulatory infertility and affects 6-15% of women of reproductive age. However, the underlying etiology is still poorly understood. In this study, we attempted to examine the association between circulating heat shock protein 70 (Hsp70 concentrations and PCOS in a non-obese Chinese population.Human peripheral blood from 52 patients with PCOS and 57 healthy controls, matched for age and BMI, were analyzed. Women with PCOS were found to have significantly higher fasting insulin (FI levels, as well as Insulin resistance index (HOMA-IR (P < 0.05. Identically, markers of oxidative stress (malondialdehyde (MDA, 8-Hydroxy-desoxyguanosine (8-OHdG, Nitric oxide (NO and inflammation (tumor necrosis factor-alpha (TNF-α, C-reactive protein (CRP were markedly increased when compared to controls (P < 0.05. Elevated serum Hsp70 was positively correlated with IR, oxidative stress and inflammation in PCOS, even after adjustment for age, BMI and gynecologic inflammation (GI. The receiver-operating characteristic curve (ROC analysis yielded notably different discriminative value for PCOS, with or without an addition of Hsp70 (areas under the curves were 0.884 (95% CI 0.822-0.946 vs. 0.822 (95% CI 0.744-0.900; P for difference = 0.015.Increased serum Hsp70 levels are associated with the combination of IR, oxidative stress and low-grade chronic inflammation in PCOS individuals, which provides supportive evidence that Hsp70 plays a key role in the pathogenesis of PCOS. More consequent studies were warranted to confirm the clinical utility of circulating Hsp70, especially in diagnosis and prognosis of PCOS and its long-term health cost.

    Inflammation increases the risk of chronic diseases, but the links between emotional responses to daily events and inflammation are unknown. We examined individual differences in affective reactivity to daily stressors (i.e., changes in positive and negative affect in response to stressors) as predictors of inflammatory markers interleukin-6 (IL-6) and C-reactive protein (CRP). A cross-sectional sample of 872 adults from the National Study of Daily Experiences (substudy of Midlife in the United States II) reported daily stressors and affect during telephone interviews for 8 days. Blood samples were obtained at a separate clinic visit and assayed for inflammatory markers. Multilevel models estimated trait affective reactivity slopes for each participant, which were inputted into regression models to predict inflammation. People who experienced greater decreases in positive affect on days when stressors occurred (i.e., positive affect reactivity) had elevated log IL-6, independent of demographic, physical, psychological, and behavioral factors (B = 1.12, SE = 0.45, p = .01). Heightened negative affect reactivity was associated with higher log CRP among women (p = .03) but not men (p = .57); health behaviors accounted for this association in women. Adults who fail to maintain positive affect when faced with minor stressors in everyday life appear to have elevated levels of IL-6, a marker of inflammation. Women who experience increased negative affect when faced with minor stressors may be at particular risk of elevated inflammation. These findings add to growing evidence regarding the health implications of affective reactivity to daily stressors. (c) 2015 APA, all rights reserved).

    Periods of short-term intensified training (IT) are often used by athletes during training cycles over the season and undergoing phases of increased physical stress may impact upon the immune system. This study investigated the effects of a period of IT on free light chains (FLCs) in saliva - an emerging immune biomarker of oral inflammation - and matched serum samples in well-trained athletes. It also examined if IT influences basal FLC levels and FLC flux during acute exercise. Highly trained male cyclists (n = 10) underwent a 9-day period of IT; before and after IT participants performed a 1 h time trial (TT) on a cycle ergometer, with blood and saliva samples collected pre- and post-exercise. FLCs were assessed in serum and saliva, and IgG, IgA, IgM and creatinine were also measured in serum. Weekly training volume increased by 143% (95% CI 114-172%), p training. Following IT, the cyclists demonstrated higher salivary FLC levels. Both salivary lambda FLC concentrations (p training, and we show for the first time that FLCs may have utility as a marker of exercise stress and oral health status. Copyright © 2018 Elsevier Inc.

    To identify preoperative nutritional and inflammatory markers that predict perioperative outcomes in patients with ovarian cancer (OC). Fifty patients who underwent primary debulking for advanced (stage III/IV) OC were selected from a cohort of patients who underwent surgery between 2002 and 2009. We analyzed C-reactive protein (CRP), interleukin-6 (IL6) and albumin and their impact on mortality and surgical outcomes. Two patients were excluded since they did not have adequate measurements of CRP and IL6. Among the remaining patients, 25 (52%) were ≥70 years old. Nine (19%), 12 (25%) and 12 (25%) patients had low serum albumin (<3.0 g/dl), elevated CRP (≥70 mg/l) and elevated IL6 (≥24 pg/ml), respectively. Age was a significant predictor of non-home discharge (p=0.01). Low serum albumin (<3.0 g/dl) was a predictor of death within 6 month (p=0.03). Elevated CRP (≥70 mg/l) was a predictor of non-home discharge (p=0.02), death within 6 months (p=0.02), death within 12 months (p=0.04), and longer hospital stay (p=0.01). Elevated IL6 (≥24 pg/ml) was a predictor of non-home discharge (p=0.002) and surgical complications (p=0.02), and also associated with longer hospital stay (p=0.03). Poor nutrition and high inflammatory status negatively influence surgical and oncological outcomes of patients with OC. These preoperative markers can be used for selection of patients for neoadjuvant chemotherapy at high risk of short survival, non-home discharge and long hospital stay.

    Accumulation of lipid droplets and inflammatory cell infiltration is the hallmark of nonalcoholic steatohepatitis (NASH). The roles of noncoding RNAs in NASH are less known. We aim to elucidate the function of miR-141/200c in diet-induced NASH. WT and miR-141/200c–/– mice were fed a methionine and choline deficient (MCD) diet for 2 weeks to assess markers of steatosis, liver injury, and inflammation. Hepatic miR-141 and miR-200c RNA levels were highly induced in human patients with NASH fatty liver and in WT MCD mice. miR-141/200c–/– MCD mice had reduced liver weights and triglyceride (TG) levels, which was associated with increased microsomal TG transfer protein (MTTP) and PPARα but reduced SREBP1c and FAS expression. Inflammation was attenuated and F4/80 macrophage activation was suppressed in miR-141/200c–/– mice, as evidenced by decreased serum aminotransferases and IL-6 and reduced hepatic proinflammatory, neutrophil, and profibrotic genes. Treatment with LPS in BM-derived macrophages isolated from miR-200c/141–/– mice polarized macrophages toward the M2 antiinflammatory state by increasing Arg1 and IL-10 levels while decreasing the M1 marker iNOS. In addition, elevated phosphorylated AMPK (p-AMPK), p-AKT, and p-GSK3β and diminished TLR4 and p-mTOR/p-4EBP1 proteins were observed. Lipidomics and metabolomics revealed alterations of TG and phosphatidylcholine (PC) lipid species by miR-141/200c deficiency. In summary, miR-141/200c deficiency diminished NASH-associated hepatic steatosis and inflammation by reprogramming lipid and inflammation signaling pathways. PMID:29093267

    Full Text Available Objective: To study the relationship of preoperative gastric cancer CT enhancement ratio and perfusion parameters with serum tumor marker levels and proliferation molecule expression in tumor lesions. Methods: A total of 68 patients with gastric cancer treated in the Second Hospital of Yulin City between May 2012 and May 2016 were chosen as observation group and sub-divided into early and middle gastric cancer group (n=41 and advanced gastric cancer group (n=27 according to the tumor stage; 50 patients diagnosed with benign gastric diseases in our hospital during the same period were selected as benign gastric lesion group. CT enhancement rate and perfusion parameters of three groups of patients were detected by CT scan, serum tumor marker levels were evacuated by enzyme-linked immunosorbent assay (ELISA, and the proliferation gene mRNA expression levels were detected by RTPCR method. Results: CER, AF, BV and CL levels of advanced gastric cancer group were higher than those of early and middle gastric cancer group and benign gastric lesion group; serum CA72-4, CA19-9, CA125 and CEA contents of advanced gastric cancer group were higher than those of early and middle gastric cancer group and benign gastric lesion group; CADM1, miRNA-34a and Cystatin M mRNA expression in tissue of advanced gastric cancer group were lower than those of early and middle gastric cancer group and benign gastric lesion group while Survivin and I2PP2A mRNA expression were higher than those of early and middle gastric cancer group and benign gastric lesion group. The Pearson test showed that the CT enhancement rate and perfusion parameters in patients with gastric cancer are directly correlated with the serum tumor marker levels and the proliferation gene expression in tumor lesions. Conclusion: Preoperative gastric cancer CT enhancement rate and perfusion parameters are directly related to the tumor malignancy, and can be used as a reliable method for the long-term tumor

    Gestational diabetes mellitus (GDM) is a risk factor for both Type 2 diabetes (DM2) and insulin-resistance syndrome (IRS). C-reactive protein (CRP), fibrinogen and leukocyte count are increased in the IRS and predict DM2 and cardiovascular disease (CVD). The chemochine monocyte chemoattractant protein-1 (MCP-1/CCL2) is also elevated in DM2 and CVD. Recent evidence suggests a relation between chronic inflammation and GDM, but post-delivery information on inflammatory markers in these high-risk women is lacking. Serum levels of CRP, fibrinogen, MCP-1/ CCL2, and leukocyte blood count have been assessed in 26 women with and 26 women without a recent history of GDM, matched for age, body mass index (BMI), post-partum duration and parity. DM2 was excluded in all the participants by an oral glucose tolerance test (OGTT). Women with previous GDM showed significantly higher CRP (p=0.007) and fibrinogen (p=0.02) serum concentrations, whereas MCP-1/CCL2 serum levels and leukocyte blood count were comparable in the two groups. Overall, CRP levels significantly correlated with BMI (r=0.40, p=0.03), waist-to-hip ratio (WHR) (r=0.44, p=0.001), fasting insulin (r=0.27, p=0.04), insulin-resistance assessed by means of the homeostatic model (HOMA) (r=0.28, p=0.04), and fibrinogen concentration (r=0.49, p=0.0001). At linear regression analysis, only WHR and fibrinogen were independently associated with CRP levels. In conclusion, the increase of inflammatory markers may be one of the first detectable disorders in healthy women at high risk of DM2 and IRS, like those with a GDM history.

    Full Text Available Abstract Background: Recently, a growing number of publications have suggested that the immune-inflammatory system may be involved in the etiology of bipolar disorder (BD. Objective: The aim of this study was to investigate neutrophil-lymphocyte ratio (NLR, platelet-lymphocyte ratio (PLR, and red cell distribution width (RDW in the three different phases of BD patients compared to each other and controls. Methods: One hundred eighty-seven bipolar patients (78 euthymic, 53 manic/hypomanic and 56 depressed, and 62 age and sex matched controls were enrolled. Sociodemographic variables and complete blood count parameters of the patients and the control group were recorded. Results: The groups did not differ from each other on the hematological parameters, except for NLR and RDW. Post-hoc analyses revealed that NLR values were significantly higher in the euthymic and manic/hypomanic bipolar groups compared to control group. In addition, post-hoc analyses revealed that RDW values were significantly higher in the manic/hypomanic bipolar group relative to the control group. Discussion: Longitudinal studies evaluating the levels of inflammatory markers in the early phases of the disorder, and their relationship with the development of different episodes and medical comorbidities may be useful to understand the role of inflammation in BD.

    In patients with melanoma, early dissemination via lymphatic and hematogenous routes is frequently seen. Thus, besides clinical follow-up examination and imaging, reliable melanoma-specific serological tumor markers are needed. We retrospectively compared two serum markers for melanoma, S100 and melanoma-inhibitory activity (MIA), for monitoring of patients with metastatic melanoma under either adjuvant or therapeutic vaccination immunotherapy with dendritic cells (DC). Serum was obtained from a total of 100 patients (28 patients in stage III and 72 patients in stage IV, according to the American Joint Committee on Cancer 2002) at regular intervals during therapy, accompanied by follow-up imaging. When relapse was detected, both markers often remained within normal range. In contrast, in patients with metastatic measurable disease receiving therapeutic and not adjuvant DC vaccination, an increase of both markers was a strong indicator for disease progression. When comparing both markers in the whole study population, MIA showed a superior sensitivity to detect disease progression. S100 and MIA are highly sensitive tumor markers for monitoring of patients with melanoma with current metastases, but less sensitive for monitoring of tumor-free patients. In the current study, MIA had a slightly superior sensitivity to detect progressive disease compared to S100 and seems to be more useful in monitoring of patients with metastatic melanoma receiving immunotherapy.

    New non-sputum biomarker tests for active tuberculosis (TB) diagnostics are of the highest priority for global TB control. We performed in-depth proteomic analysis using the 4,000-plex SOMAscan assay on 1,470 serum samples from seven countries where TB is endemic. All samples were from patients with symptoms and signs suggestive of active pulmonary TB that were systematically confirmed or ruled out for TB by culture and clinical follow-up. HIV coinfection was present in 34% of samples, and 25% were sputum smear negative. Serum protein biomarkers were identified by stability selection using L1-regularized logistic regression and by Kolmogorov-Smirnov (KS) statistics. A naive Bayes classifier using six host response markers (HR6 model), including SYWC, kallistatin, complement C9, gelsolin, testican-2, and aldolase C, performed well in a training set (area under the sensitivity-specificity curve [AUC] of 0.94) and in a blinded verification set (AUC of 0.92) to distinguish TB and non-TB samples. Differential expression was also highly significant ( P CA6 (carbonic anhydrase 6). Target product profiles (TPPs) for a non-sputum biomarker test to diagnose active TB for treatment initiation (TPP#1) and for a community-based triage or referral test (TPP#2) have been published by the WHO. With 90% sensitivity and 80% specificity, the HR6 model fell short of TPP#1 but reached TPP#2 performance criteria. In conclusion, we identified and validated a six-marker signature for active TB that warrants diagnostic development on a patient-near platform. Copyright © 2017 De Groote et al.

    It has previously been reported that increased level of serum heat shock proteins (Hsps) antibody in patients with metabolic syndrome. It is possible that the expression of Hsp and inflammatory markers can be affected by cupping and traditional Chinese medicine. There is a little data investigating the effects of cupping on markers of inflammation and Hsp proteins, hence, the objective of this study was evaluation of the effects of wet cupping on serum high-sensitivity C-reactive protein (hs-CRP) and Hsp27 antibody titers in patients with metabolic syndrome. Serum Hs-CRP and Hsp27 antibody titers were assessed in samples from 126 patients with metabolic syndrome (18-65 years of age) at baseline, and after 6 and 12 weeks after treatment. One hundred and twenty-six patients were randomly divided into the experimental group treated with wet cupping combined with dietary advice, and the control group treated with dietary advice alone using a random number table. Eight patients in case group and five subjects in control groups were excluded from the study. Data were analyzed using SPSS 15.0 software and a repeated measure ANCOVA. Serum hs-CRP titers did not change significantly between groups (p>0.05) and times (p=0.27). The same result was found for Hsp27 titers (p>0.05). Wet-cupping on the interscapular region has no effect on serum hs-CRP and Hsp27 patients with metabolic syndrome. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Levels of sCD30 represent a biomarker for early outcome in kidney transplantation. The purpose of this study was to determine the role of sCD30 levels for prediction of graft loss in the late post-transplant period. Sera were collected immediately pre-transplant and yearly thereafter for up to 5-year post-transplant in 37 primary renal transplant recipients. Levels of serum sCD30 were tested using a fluorescent microsphere assay. Levels of sCD30 significantly decreased after transplantation and remained normal in 34 patients without graft loss up to 5-year post-transplant. Elevated levels of serum sCD30 preceded the increase of serum creatinine in patients with subsequent graft loss. Elevated levels of serum sCD30 post-transplant might be a marker for predicting subsequent graft loss in the post-transplant period.

  16. Use of Readily Accessible Inflammatory Markers to Predict Diabetic Kidney Disease

    2018-05-01

    Full Text Available Diabetic kidney disease is a common complication of type 1 and type 2 diabetes and is the primary cause of end-stage renal disease in developed countries. Early detection of diabetic kidney disease will facilitate early intervention aimed at reducing the rate of progression to end-stage renal disease. Diabetic kidney disease has been traditionally classified based on the presence of albuminuria. More recently estimated glomerular filtration rate has also been incorporated into the staging of diabetic kidney disease. While albuminuric diabetic kidney disease is well described, the phenotype of non-albuminuric diabetic kidney disease is now widely accepted. An association between markers of inflammation and diabetic kidney disease has previously been demonstrated. Effector molecules of the innate immune system including C-reactive protein, interleukin-6, and tumor necrosis factor-α are increased in patients with diabetic kidney disease. Furthermore, renal infiltration of neutrophils, macrophages, and lymphocytes are observed in renal biopsies of patients with diabetic kidney disease. Similarly high serum neutrophil and low serum lymphocyte counts have been shown to be associated with diabetic kidney disease. The neutrophil–lymphocyte ratio is considered a robust measure of systemic inflammation and is associated with the presence of inflammatory conditions including the metabolic syndrome and insulin resistance. Cross-sectional studies have demonstrated a link between high levels of the above inflammatory biomarkers and diabetic kidney disease. Further longitudinal studies will be required to determine if these readily available inflammatory biomarkers can accurately predict the presence and prognosis of diabetic kidney disease, above and beyond albuminuria, and estimated glomerular filtration rate.

    Wheezing is common in childhood. However, current prediction models of pediatric asthma have only modest accuracy. Novel biomarkers and definition of subphenotypes may improve asthma prediction. Interleukin-1-receptor-like-1 (IL1RL1 or ST2) is a well-replicated asthma gene and associates with eosinophilia. We investigated whether serum sST2 predicts asthma and asthma with elevated exhaled NO (FeNO), compared to the commonly used Asthma Prediction Index (API). Using logistic regression modeling, we found that serum sST2 levels in 2-3 years-old wheezers do not predict doctors' diagnosed asthma at age 6 years. Instead, sST2 predicts a subphenotype of asthma characterized by increased levels of FeNO, a marker for eosinophilic airway inflammation. Herein, sST2 improved the predictive value of the API (AUC=0.70, 95% CI 0.56-0.84), but had also significant predictive value on its own (AUC=0.65, 95% CI 0.52-0.79). Our study indicates that sST2 in preschool wheezers has predictive value for the development of eosinophilic airway inflammation in asthmatic children at school age. © 2017 EAACI and John Wiley and Sons A/S.

    At present, the research on serum tumor markers in the early diagnosis of malignant tumors has aroused widespread concern. The aim of this study was to investigate the diagnostic values of serum tumor markers cytokeratin 19 fragment (Cyfra21-1), squamous cell carcinoma antigen (SCCAg), ferritin, carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and α-fetoprotein (AFP) for patients with oral/oropharyngeal squamous carcinoma (OSCC/OPSCC). One hundred and sixty-nine cases of patients with OSCC/OPSCC as the experimental group, 86 cases of oral benign tumor patients as the control group, and 30 cases of healthy people as the normal control group were studied. The levels of serum Cyfra21-1, SCCAg, ferritin, CEA, CA19-9, and AFP were measured using electrochemiluminescence immunoassay. The levels of serum Cyfra21-1, SCCAg, ferritin, and CEA in patients with OSCC/OPSCC were significantly higher than those of benign tumor and healthy control group (Ptumor, and healthy group (P>0.05). The level of serum Cyfra21-1 in patients with early OSCC/OPSCC (stage I + II) was significantly higher than that of benign tumor and healthy control group (PCEA, CA19-9, and AFP showed no significant difference between patients with early OSCC/OPSCC, benign tumor, and healthy control group (P>0.05). The levels of serum Cyfra21-1, SCCAg, ferritin, and CEA in the middle-late stage of patients with OSCC/OPSCC (stage III + IV) were significantly higher than those of patients with the early OSCC/OPSCC, benign tumor, and healthy control group (PCEA were 2.17, 0.72, 109.95, and 1.99 ng/mL, respectively. The sensitivities were 60.36%, 73.37%, 81.66%, and 66.27%, respectively. The specificities were 81.03%, 68.10%, 40.52%, and 61.21%, respectively. Cyfra21-1, SCCAg, ferritin, and CEA had diagnostic values for patients with OSCC/OPSCC. Meanwhile, Cyfra21-1 had better early diagnostic value for patients with OSCC/OPSCC.

    AIM: To evaluate the correlation between liver stiffness measurement (LSM) by real-time shear wave elastography (SWE) and liver fibrosis stage and the accuracy of LSM for predicting significant and advanced fibrosis, in comparison with serum markers. METHODS: We consecutively analyzed 70 patients with various chronic liver diseases. Liver fibrosis was staged from F0 to F4 according to the Batts and Ludwig scoring system. Significant and advanced fibrosis was defined as stage F ≥ 2 and F ≥ 3, respectively. The accuracy of prediction for fibrosis was analyzed using receiver operating characteristic curves. RESULTS: Seventy patients, 15 were belonged to F0-F1 stage, 20 F2, 13 F3 and 22 F4. LSM was increased with progression of fibrosis stage (F0-F1: 6.77 ± 1.72, F2: 9.98 ± 3.99, F3: 15.80 ± 7.73, and F4: 22.09 ± 10.09, P < 0.001). Diagnostic accuracies of LSM for prediction of F ≥ 2 and F ≥ 3 were 0.915 (95%CI: 0.824-0.968, P < 0.001) and 0.913 (95%CI: 0.821-0.967, P < 0.001), respectively. The cut-off values of LSM for prediction of F ≥ 2 and F ≥ 3 were 8.6 kPa with 78.2% sensitivity and 93.3% specificity and 10.46 kPa with 88.6% sensitivity and 80.0% specificity, respectively. However, there were no significant differences between LSM and serum hyaluronic acid and type IV collagen in diagnostic accuracy. CONCLUSION: SWE showed a significant correlation with the severity of liver fibrosis and was useful and accurate to predict significant and advanced fibrosis, comparable with serum markers.

    Full Text Available Background: One of the major direct or indirect targets of ultraviolet exposure of skin is the melanocyte or the melanin -forming cell. Epidermal melanocytes act as a trap for free radicals. Based on the protective role of melanocytes in medical literature, the role of melanin pigmentation in gingiva needs to be elucidated. Periodontal pathogens and their products demonstrate the ability to induce the generation of reactive oxygen species. Hence purpose of this study was to unravel the protective role of melanin (if any against the gingival inflammation. Materials and Methods: A total of 80 subjects; 20 in each group were selected. The selection of subjects regarding gingival pigmentation was based on Dummett′s scoring criteria 0, 3. A complete medical, dental history and an informed consent were obtained from the patients. After evaluation of clinical parameters the GCF was collected using microcapillary pipettes at the selected sites. IL-1β levels were quantitated using ELISA. Results: In non-pigmented healthy and gingivitis groups, there was a positive correlation between plaque index, gingival index and bleeding index versus IL-1β level: indicating an increase in the biochemical mediator of inflammation corresponding to an increase in the clinical parameters of inflammation. Also a positive correlation was found between the gingival index and bleeding index versus the IL-1β levels in the pigmented healthy group. The pigmented gingivitis groups showed a negative correlation between the plaque index, gingival index and bleeding index. Conclusions: The clinical markers of inflammation such as gingival index, bleeding index was of low numerical value in pigmented group than in the non-pigmented group, supposedly due to the protective action of melanin. The negative correlation of clinical markers of inflammation to the IL-1β levels in the pigmented gingivitis group could possibly be attributed to the protective role of melanins.

    Full Text Available Background: Different measures of body fat composition may vary in their relations to parameters of chronic inflammation. Methods: We assessed the relations of visceral (VAT and subcutaneous adipose tissue (SAT, BMI, and waist circumference (WC to serum concentrations of high-sensitive C-reactive protein (hs-CRP, tumor necrosis factor alpha (TNF-α, interleukin-6 (IL-6, resistin, and adiponectin in 97 healthy adults using multivariate linear regression models, adjusted for age, sex, smoking, physical activity, menopausal status, and use of aspirin or non-steroidal anti-inflammatory drugs (NSAIDs. Parameters of chronic inflammation were mutually adjusted. Results: VAT (β = 0.34, SAT (β = 0.43, BMI (β = 0.40, and WC (β = 0.47 were all significantly associated with hs-CRP. BMI was additionally inversely related to adiponectin (β = -0.29. In exploratory subgroup analyses defined by gender, BMI, smoking, and use of aspirin or NSAIDs, VAT was the strongest indicator for increased levels of IL-6, SAT was the most consistent indicator for increased levels of hs-CRP, and BMI was the most consistent indicator for decreased levels of adiponectin. WC showed to be a weak indicator for increased levels of hs-CRP and decreased levels of adiponectin. Conclusion: VAT, SAT, BMI, and WC show distinct associations with parameters of chronic inflammation. Whether these differences reflect differential metabolic risks requires clarification by longitudinal studies.

    Functionalized giant unilamellar vesicles (GUVs) containing a fluorescence dye Rhodamine 6G is proposed as a marker in sandwich-type immunoassay for bovine serum albumin (BSA) and lipocalin-2 (LCN2). The GUVs were prepared by the electroformation method and functionalized with anti-BSA antibody and anti-LCN2 antibody, respectively. The purification of antibody-modified GUVs was achieved by conventional centrifugation and a washing step in a flow system. To antigen on an antibody slip, antibody-modified GUVs were added as a marker and incubated. After wash-out of excess reagents and lysis of the bound GUVs with Triton X-100, the fluorescence image was captured. The fluorometric immunoassays for BSA and LCN2 exhibited lower detection limits of 4 and 80 fg ml(-)(1), respectively. Copyright © 2016 Elsevier Inc. All rights reserved.

    To evaluate the effect of the daily intake of a fruit & vegetable soup with high in vitro bioaccessibility of carotenoids on β-carotene and lycopene serum concentrations. Fourteen healthy young men (24 ± 1 years) received 300 mL/day of a carrot, tomato, and broccoli soup, containing 3.9 mg β-carotene and 4 mg lycopene, for 4 weeks followed by a 4-week washout period. The serum carotenoid response and oxidative markers were analyzed after 3 and 4 weeks of soup consumption and after a 4-week washout. The in vitro bioaccessibility of β-carotene and lycopene was 55 and 43%, respectively, in the soup. Serum β-carotene concentrations were significantly higher than baseline (0.33 ± 0.05 μmol/L) after 3 weeks (0.69 ± 0.06 μmol/L) and 4 weeks (0.78 ± 0.10 μmol/L) of soup consumption (P soup supplementation compared with baseline, while superoxide dismutase was significantly lower only after 3 weeks. Glutathione reductase, lipid, protein, and DNA oxidative markers remained unchanged. The soup contributed to increasing the concentration of each carotenoid by more than 100% after 3 and 4 weeks of consumption, the maximum increase being observed after 4 weeks. Oxidative markers did not show any variation except for GPx. Serum lycopene half-life was longer than that of β-carotene, which may be important for studies evaluating both carotenoids.

    To compare the effects of an orally administered corticosteroid (prednisone), an inhaled corticosteroid (flunisolide), a leukotriene-receptor antagonist (zafirlukast), an antiserotonergic drug (cyproheptadine), and a control substance on the asthmatic phenotype in cats with experimentally induced asthma. 6 cats with asthma experimentally induced by the use of Bermuda grass allergen (BGA). A randomized, crossover design was used to assess changes in the percentage of eosinophils in bronchoalveolar lavage fluid (BALF); airway hyperresponsiveness; blood lymphocyte phenotype determined by use of flow cytometry; and serum and BALF content of BGA-specific IgE, IgG, and IgA determined by use of ELISAs. Mean +/- SE eosinophil percentages in BALF when cats were administered prednisone (5.0 +/- 2.3%) and flunisolide (2.5 +/- 1.7%) were significantly lower than for the control treatment (33.7 +/- 11.1%). We did not detect significant differences in airway hyperresponsiveness or lymphocyte surface markers among treatments. Content of BGA-specific IgE in serum was significantly lower when cats were treated with prednisone (25.5 +/- 5.4%), compared with values for the control treatment (63.6 +/- 12.9%); no other significant differences were observed in content of BGA-specific immunoglobulins among treatments. Orally administered and inhaled corticosteroids decreased eosinophilic inflammation in airways of cats with experimentally induced asthma. Only oral administration of prednisone decreased the content of BGA-specific IgE in serum; no other significant local or systemic immunologic effects were detected among treatments. Inhaled corticosteroids can be considered as an alternate method for decreasing airway inflammation in cats with asthma.

    Full Text Available Markers of the systemic inflammatory response, including C-reactive protein and albumin (combined to form the modified Glasgow Prognostic Score, as well as neutrophil, lymphocyte and platelet counts have been shown to be prognostic of survival in patients with cancer. The aim of the present study was to examine the prognostic relationship between these markers of the systemic inflammatory response and all-cause, cancer, cardiovascular and cerebrovascular mortality in a large incidentally sampled cohort.Patients (n = 160 481 who had an incidental blood sample taken between 2000 and 2008 were studied for the prognostic value of C-reactive protein (>10mg/l, albumin (>35mg/l, neutrophil (>7.5×109/l lymphocyte and platelet counts. Also, patients (n = 52 091 sampled following the introduction of high sensitivity C-reactive protein (>3mg/l measurements were studied. A combination of these markers, to make cumulative inflammation-based scores, were investigated.In all patients (n = 160 481 C-reactive protein (>10mg/l (HR 2.71, p35mg/l (HR 3.68, p3mg/l (n = 52 091. A combination of high sensitivity C-reactive protein (>3mg/l, albumin and neutrophil count predicted all-cause (HR 7.37, p<0.001, AUC 0.723, cancer (HR 9.32, p<0.001, AUC 0.731, cardiovascular (HR 4.03, p<0.001, AUC 0.650 and cerebrovascular (HR 3.10, p<0.001, AUC 0.623 mortality.The results of the present study showed that an inflammation-based prognostic score, combining high sensitivity C-reactive protein, albumin and neutrophil count is prognostic of all-cause mortality.

    Inflammation may be involved in the pathophysiology of schizophrenia. However, few cross-sectional or longitudinal studies have examined changes in biomarker expression to evaluate diagnostic and prognostic efficacy in acute-stage schizophrenia. We compared serum inflammatory biomarker concentrations in 87 patients with acute-stage schizophrenia on admission to 105 age-, sex-, and body mass index (BMI)-matched healthy controls. The measured biomarkers were soluble tumor necrosis factor receptor 1 (sTNFR1) and adiponectin, which are associated with inflammatory responses, and pigment epithelium-derived factor (PEDF), which has anti-inflammatory properties. We then investigated biomarker concentrations and associations with clinical factors in 213 patients (including 42 medication-free patients) and 110 unmatched healthy controls to model conditions typical of clinical practice. Clinical symptoms were assessed using the Brief Psychiatric Rating Scale and Global Assessment of Function. In 121 patients, biomarker levels and clinical status were evaluated at both admission and discharge. Serum sTNFR1 was significantly higher in patients with acute-stage schizophrenia compared to matched controls while no significant group differences were observed for the other markers. Serum sTNFR1 was also significantly higher in the 213 patients compared to unmatched controls. The 42 unmedicated patients had significantly lower PEDF levels compared to controls. Between admission and discharge, sTNFR1 levels decreased significantly; however, biomarker changes did not correlate with clinical symptoms. The discriminant accuracy of sTNFR1 was 93.2% between controls and patients, showing no symptom improvement during care. Inflammation and a low-level anti-inflammatory state may be involved in both schizophrenia pathogenesis and acute-stage onset. High serum sTNFR1 in the acute stage could be a useful prognostic biomarker for treatment response in clinical practice. Copyright © 2017

  9. Molecular Ultrasound Imaging for the Detection of Neural Inflammation

    Science.gov (United States)

    Volz, Kevin R.

    Molecular imaging is a form of nanotechnology that enables the noninvasive examination of biological processes in vivo. Radiopharmaceutical agents are used to selectively target biochemical markers, which permits their detection and evaluation. Early visualization of molecular variations indicative of pathophysiological processes can aid in patient diagnoses and management decisions. Molecular imaging is performed by introducing molecular probes into the body. Molecular probes are often contrast agents that have been nanoengineered to selectively target and tether to molecules, enabling their radiologic identification. Ultrasound contrast agents have been demonstrated as an effective method of detecting perfusion at the tissue level. Through a nanoengineering process, ultrasound contrast agents can be targeted to specific molecules, thereby extending ultrasound's capabilities from the tissue to molecular level. Molecular ultrasound, or targeted contrast enhanced ultrasound (TCEUS), has recently emerged as a popular molecular imaging technique due to its ability to provide real-time anatomical and functional information in the absence of ionizing radiation. However, molecular ultrasound represents a novel form of molecular imaging, and consequently remains largely preclinical. A review of the TCEUS literature revealed multiple preclinical studies demonstrating its success in detecting inflammation in a variety of tissues. Although, a gap was identified in the existing evidence, as TCEUS effectiveness for detection of neural inflammation in the spinal cord was unable to be uncovered. This gap in knowledge, coupled with the profound impacts that this TCEUS application could have clinically, provided rationale for its exploration, and use as contributory evidence for the molecular ultrasound body of literature. An animal model that underwent a contusive spinal cord injury was used to establish preclinical evidence of TCEUS to detect neural inflammation. Imaging was

    Serum ferritin level is one of the most commonly requested investigations in both primary and secondary care. Whilst low serum ferritin levels invariably indicate reduced iron stores, raised serum ferritin levels can be due to multiple different aetiologies, including iron overload, inflammation, liver or renal disease, malignancy, and the recently described metabolic syndrome. A key test in the further investigation of an unexpected raised serum ferritin is the serum transferrin saturation. This guideline reviews the investigation and management of a raised serum ferritin level. The investigation and management of genetic haemochromatosis is not dealt with however and is the subject of a separate guideline. © 2018 John Wiley & Sons Ltd.

    Xuanwei City is located in late Permian coal-accumulating areas of the northeastern region of Yunnan Province. In China, morbidity and mortality from lung cancer are highest in Yunnan. Identifying useful circulating markers suitable for the diagnosis of lung cancer in this region is quite meaningful. In this study, we evaluated diagnostic roles of serum miR-9-5p, 21-5p, 223-3p, 135b-5p, 339-5p, and 501-5p in patients with non-small-cell lung cancer (NSCLC) in Yunnan. Moreover, we evaluated the diagnostic performance of several tumor markers, including carcinoembryonic antigen (CEA), cytokeratin 19 fragment 21-1 (CYFRA21-1), and squamous cell carcinoma-related antigen (SCC). Quantitative real-time polymerase chain reaction detected six miRNAs in the serum of 104 NSCLC patients and 50 cancer-free controls. Other markers, including CEA, CYFRA21-1, and SCC, in serum were also measured. The diagnostic ability of miRNAs and tumor markers was evaluated by receiver operating characteristic (ROC) curve analysis. The diagnostic performance of these serum markers was also evaluated in Xuanwei and non-Xuanwei subjects, because the etiological and the epidemiological characteristics of lung cancer in Xuanwei were quite different from those in other regions. Serum miR-9-5p, miR-21-5p, miR-223-3p, CEA, CYFRA21-1, and SCC were upregulated in NSCLC patients, compared with cancer-free controls. No significant difference was found in miR-135b-5p, miR-339-5p, and miR-501-5p expression. The area under ROC curves (AUCs) of miR-9-5p, miR-21-5p, miR-223-3p, CEA, CYFRA21-1, and SCC were 0.706, 0.765, 0.744, 0.749, 0.735, and 0.616, respectively. When combined, miRNAs and tumor markers yielded the highest diagnostic power, with AUC of 0.886, sensitivity of 82.69%, and specificity of 88.00%. In Xuanwei subjects, miR-223-3p and CEA may be suitable biomarkers to distinguish NSCLC from cancer-free states with AUCs of 0.752 and 0.791, respectively. The diagnostic power of the combination of mi

    Acute rejection (AR) remains a major cause for long-term kidney allograft failure. Reliable immunological parameters suitable to define the pre-transplant immune state and hence the individual risk of graft rejection are highly desired to preferably adapt the immunosuppressive regimen in advance. Donor and third party alloreactivities were determined by mixed lymphocyte cultures. Soluble forms of CD25, CD30, and CD44 were detected in patients' serum by ELISA. Various lymphocyte subpopulations were measured using flow cytometry. All patients received triple immunosuppression (tacrolimus/mycophenolate mofetil/steroids) and were grouped according to biopsy results within the first year: rejection-free (RF, n = 13), borderline (BL, n = 5), or acute rejection (AR, n = 7). Patients with AR showed the highest pre-transplant alloreactivities and serum levels (sCD25/sCD30/sCD44) according to the pattern RF transplant frequencies of CD4(+) /CD8(+) T cells lacking CD28, but lower numbers of CD8(+) CD161(bright) T cells and NK cells than RF individuals. Pre-transplant immune state defined by alloreactivity, serum markers, and particular lymphocyte subsets seems to correlate with occurrence of graft rejection after kidney transplantation. A prognostic score based on pre-transplant serum levels has shown great potential for prediction of rejection episodes and should be further evaluated. © 2014 John Wiley & Sons A/S.

    We determined the effect of hyperandrogenemia as observed in polycystic ovary syndrome (PCOS) on fasting and glucose-stimulated proatherogenic inflammation markers in lean healthy reproductive-age women. Sixteen lean healthy ovulatory reproductive-age women were treated with 130 mg of DHEA or placebo (n=8 each) for 5 days. Interleukin-6 (IL-6) mRNA and IL-6 release from mononuclear cells (MNC), plasma IL-6 and C-reactive protein (CRP), and MNC-derived (matrix metalloproteinase-2) MMP-2 protein were quantified in the fasting state and 2 h after glucose ingestion, before and after treatment. Before treatment, subjects receiving dehydroepinadrosterone (DHEA) or placebo exhibited no differences in androgens, or any proatherogenic inflammation markers while fasting and after glucose ingestion. Compared with placebo, DHEA administration raised levels of testosterone, androstenedione, and DHEA-sulfate (DHEA-S), and increased the percent change from baseline in fasting IL-6 mRNA, IL-6 release, plasma IL-6, and CRP and MMP-2 protein. However, there were no differences in any of the proatherogenic inflammation markers following glucose ingestion after DHEA administration. We conclude that in lean reproductive-age women, proatherogenic inflammation in the fasting state increases after raising circulating androgens to levels observed in PCOS. However, this hyperandrogenemia-induced MNC activation does not provoke a similar response to subsequent glucose ingestion. © Georg Thieme Verlag KG Stuttgart · New York.

    In order to find out the correlations between serum leptin levels and viral hepatitis, the serum leptin levels in 167 patients with viral chronic hepatitis, 87 patients with fatty liver, and 80 control subjects were determined by radioimmunoassay. The liver function (ALT, AST), glucose(Glu) and total cholesterol(TC) in these patients were also measured. Compared with controls and patients with fatty liver, the levels of serum leptin in patients with viral hepatitis were significantly increased (P 0.05). The increase of serum leptin levels in the patients with viral hepatitis was correlated positively with the severity of liver inflammation. Therefore, the leptin can be regarded as an indicator to reflect the severity of liver inflammation. (authors)

    Psoriasis is a refractory inflammatory disease, however, its pathophysiology is still not fully understood. We tried to identify novel serum peptides associated with the pathophysiology of psoriasis. Serum peptides from 24 patients with psoriasis vulgaris (PV), 10 patients with psoriatic arthritis (PsA), 14 patients with atopic dermatitis (AD), and 23 healthy control (HC) subjects were analyzed by mass spectrometry. The effects of some peptides on the secretion of humoral factors from dermal cells were investigated by cytokine arrays and ELISAs. A total of 93 peptides were detected. 24, 20, 23, and 2 peptides showed at least 1.2-fold difference in ion intensity between the psoriasis (PV+PsA) and HC groups, between the PV+PsA and AD groups, between the PV and PsA groups, and between patients with severe-to-moderate PV (n=6) and those with mild PV (n=18), respectively (ppsoriasis, regulating the secretion of inflammatory chemokines and an antimicrobial protein. The modulation of serum peptides may be a potential therapeutic strategy for psoriasis. Copyright © 2017 Japanese Society for Investigative Dermatology. Published by Elsevier B.V.

  17. The Impact of Exercising During Haemodialysis on Blood Pressure, Markers of Cardiac Injury and Systemic Inflammation - Preliminary Results of a Pilot Study

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Background/Aims: Patients requiring haemodialysis have cardiovascular and immune dysfunction. Little is known about the acute effects of exercise during haemodialysis. Exercise has numerous health benefits but in other populations has a profound impact upon blood pressure, inflammation and immune function; therefore having the potential to exacerbate cardiovascular and immune dysfunction in this vulnerable population. Methods: Fifteen patients took part in a randomised-crossover study investigating the effect of a 30-min bout of exercise during haemodialysis compared to resting haemodialysis. We assessed blood pressure, plasma markers of cardiac injury and systemic inflammation and neutrophil degranulation. Results: Exercise increased blood pressure immediately post-exercise; however, 1 hour after exercise blood pressure was lower than resting levels (106±22 vs. 117±25 mm Hg. No differences in h-FABP, cTnI, myoglobin or CKMB were observed between trial arms. Exercise did not alter circulating concentrations of IL-6, TNF-α or IL-1ra nor clearly suppress neutrophil function. Conclusions: This study demonstrates fluctuations in blood pressure during haemodialysis in response to exercise. However, since the fall in blood pressure occurred without evidence of cardiac injury, we regard it as a normal response to exercise superimposed onto the haemodynamic response to haemodialysis. Importantly, exercise did not exacerbate systemic inflammation or immune dysfunction; intradialytic exercise was well tolerated.

    Elevation of serum high sensitivity C-reactive protein (hs-CRP) level has been demonstrated as a risk factor for varying diseases, as well as a biomarker for predicting recovery after operation of lumber disc herniation. Our objective was to investigate the relationship between serum hs-CRP and sacroiliac (SI) joint inflammation in patients with undifferentiated spondyloarthritis (uSpA). In this retrospective study, we enrolled patients with uSpA who underwent hs-CRP testing between January 2007 and September 2013. Serum hs-CRP was analyzed at our central laboratory. All enrolled patients underwent skeletal scintigraphic scan with quantitative sacroiliac measurement. A total of 29 patients were enrolled with mean age 32.27 years and female:male ratio of 6:23. Pearson's correlation coefficient showed a significant difference between hs-CRP in serum and SI/S ratio in uSpA, particularly the middle part of the sacroiliac joint, either right side or left side. The significantly high concentration of serum hs-CRP might indicate a systemic inflammatory response to flare-up of the SI joint and might be an indicator of SI inflammation in uSpA.

    Mercury is an immunotoxic substance that has been shown to induce autoimmune disease in rodent models, characterized by lymphoproliferation, overproduction of immunoglobulin (IgG and IgE), and high circulating levels of auto-antibodies directed at antigens located in the nucleus (antinuclear auto-antibodies, or ANA) or the nucleolus (antinucleolar auto-antibodies, or ANoA). We have reported elevated levels of ANA and ANoA in human populations exposed to mercury in artisanal gold mining, though other confounding variables that may also modulate ANA/ANoA levels were not well controlled. The goal of this study is to specifically test whether occupational and environmental conditions (other than mercury exposure) that are associated with artisanal gold mining affect the prevalence of markers of autoimmune dysfunction. We measured ANA, ANoA, and cytokine concentrations in serum and compared results from mercury-exposed artisanal gold miners to those from diamond and emerald miners working under similar conditions and with similar socio-economic status and risks of infectious disease. Mercury-exposed gold miners had higher prevalence of detectable ANA and ANoA and higher titers of ANA and ANoA as compared to diamond and emerald miners with no occupational mercury exposure. Also, mercury-exposed gold miners with detectable ANA or ANoA in serum had significantly higher concentrations of pro-inflammatory cytokines IL-1beta, TNF-alpha, and IFN-gamma in serum as compared to the diamond and emerald miners. This study provides further evidence that mercury exposure may lead to autoimmune dysfunction and systemic inflammation in affected populations. Copyright 2010 Elsevier Inc. All rights reserved.

    A microsystem integrating electrochemical biosensoric detection for the simultaneous multiplexed detection of protein markers of breast cancer is reported. The immobilization of antibodies against each of carcinoembryonic antigen (CEA), prostate specific antigen (PSA) and cancer antigen 15-3 (CA15-3) was achieved via crosslinking to a bipodal dithiol chemisorbed on gold electrodes. This bipodal dithiol had the double function of eliminating non-specific binding and optimal spacing of the anchor antibodies for maximum accessibility to the target proteins. Storage conditions were optimized, demonstrating a long-term stability of the reporter conjugates jointly stored within a single reservoir in the microsystem. The final system has been optimized in terms of incubation times, temperatures and simultaneous, multiplexed detection of the protein markers was achieved in less than 10 minutes with less than ng/mL detection limits. The microsystem has been validated using real patient serum samples and excellent correlation with ELISA results obtained.

    Women have a consistently higher prevalence of major depressive disorder (MDD) than men. Hypotheses implicating hypothalamic-pituitary -adrenal, -gonadal, and -thyroid axes, immune response, genetic factors, and neurotransmitters have emerged to explain this difference. However, more evidence for these hypotheses is needed and new explanations must be explored. Here, we investigated sex differences in MDD markers using multiplex immunoassay measurements of 171 serum molecules in individuals enrolled in the Netherlands Study of Depression and Anxiety (NMDD = 231; Ncontrol = 365). We found 28 sex-dependent markers of MDD, as quantified by a significant interaction between sex and log2-transformed analyte concentration in a logistic regression with diagnosis (MDD/control) as the outcome variable (pdepression to males and females and have important implications for the development of diagnostic biomarker tests for MDD. More studies are needed to validate these results, investigate a broader range of biological pathways, and integrate this data with brain imaging, genetic, and other relevant data.

    Chronically elevated circulating inflammatory markers are common in older persons but mechanisms are unclear. Many blood transcripts (>800 genes) are associated with interleukin-6 protein levels (IL6) independent of age. We aimed to identify gene transcripts statistically mediating, as drivers or responders, the increasing levels of IL6 protein in blood at older ages. Blood derived in-vivo RNA from the Framingham Heart Study (FHS, n=2422, ages 40-92 yrs) and InCHIANTI study (n=694, ages 30-104 yrs), with Affymetrix and Illumina expression arrays respectively (>17,000 genes tested), were tested for statistical mediation of the age-IL6 association using resampling techniques, adjusted for confounders and multiple testing. In FHS, IL6 expression was not associated with IL6 protein levels in blood. 102 genes (0.6% of 17,324 expressed) statistically mediated the age-IL6 association of which 25 replicated in InCHIANTI (including 5 of the 10 largest effect genes). The largest effect gene (SLC4A10, coding for NCBE, a sodium bicarbonate transporter) mediated 19% (adjusted CI 8.9 to 34.1%) and replicated by PCR in InCHIANTI (n=194, 35.6% mediated, p=0.01). Other replicated mediators included PRF1 (perforin, a cytolytic protein in cytotoxic T lymphocytes and NK cells) and IL1B (Interleukin 1 beta): few other cytokines were significant mediators. This transcriptome-wide study on human blood identified a small distinct set of genes that statistically mediate the age-IL6 association. Findings are robust across two cohorts and different expression technologies. Raised IL6 levels may not derive from circulating white cells in age related inflammation. Published by Elsevier Inc.

    There was few study concentrated on the correlation between the evaluated tumor markers and lymph node metastasis. In this study, we aimed to evaluate the correlation between the CA724, CA242, CA199, CEA and the lymph node metastasis of gastric cancer and assess the prognostic value of them in different N stage patients. We analyzed the correlation between serum level of CA724, CA242, CA199, CEA and lymph node metastasis in 1501 gastric cancer patients. Lymph node metastasis of gastric cancer was related with tumor location, Bormann type, tumor size, histological type, depth of invasion and TNM stage (p CEA were positively correlated with the metastatic lymph node counts and the N stage (p tumor markers were higher (p tumor markers, the positive rates of tumor markers combination were higher. The combination of CA724 + CA242 + CA199 + CEA had highest positive rate. The higher CEA level related to N1 stage patients while higher CA199 was related with poor prognosis for N1 stage patients. For N0 and N2 stage patients, evaluation of CA724 indicated poorer prognosis. For N1 and N2 stage gastric patients, the patients with increased CA242 inclined to have shorter survival time. The tumor makers CA724, CA242, CA199 and CEA were evaluated significantly in the gastric patients with later N stage. The combination of these four tumor markers maybe prefer diagnostic index of gastric cancer and its lymph node metastasis. These tumor markers can be a possible indicator of poorer prognosis in different N stage patients.

    Although quartz is known to induce inflammation in rat lungs, mechanisms are not yet fully understood. The importance of particle surface characteristics was investigated in vivo after intratracheal instillation of different preparations of quartz in rat lungs. Three days after instillation of 2 mg DQ12 quartz, or DQ12 coated with polyvinylpyridine-N-oxide (PVNO) or Aluminium lactate (AL), lungs of female Wistar rats were lavaged in situ to determine markers of inflammation. Control rats received saline or the coating substances alone. DQ12 induced a marked inflammatory response, as indicated by a significant increase in the number of neutrophils and macrophages, as well as in the levels of b-glucuronidase and myeloperoxidase. None of these inflammatory markers was increased for both coated quartz preparations, with the exception of neutrophil influx which was also increased after treatment with AL quartz. Our results indicate that surface characteristics are important in the onset of quartz-induced lung inflammation which could imply a different development of persistent inflammation. This will be investigated in later follow-up time points of the same animal study. (orig.)

    Full Text Available Introduction. Ankylosing spondylitis (AS is a chronic inflammatory disease that affects sacroiliac joints, spinal column and peripheral joints. Beside medication therapy, physical and balneotherapy play an important role in its complex treatment. Objective. The aim of the research was to establish serum concentrations of C-reactive protein (CRP, α 1-acid glycoprotein (α 1-AGP, ceruloplasmine (CP and erythrocyte sedimentation rate (SE before and after the balneotherapy in ankylosing spondylitis. Methods. The research included 50 AS patients according to the revised New York criteria, of mean age 43 years, who were treated for 14 days on the average at the Clinic for Rheumatology of the Institute 'Niška Banja'. All the patients received medications and balneotherapy (radioactive oligomineral baths, peloid, massage, kinesitherapy; the serum concentrations of CRP, α1-AGP, CP and SE were measured before and after balneotherapy. Serum proteins were determined using original Nor Partigen plates Boehringer. Erythrocyte sedimentation rate was measured by Westergreen method. Balneotherapy was applied individually, intensively or mildly, depending on the AS stage and activity phase. Results. After dosed balneotherapy, a significant decrease in the concentrations of CP (p<0.05, α1-AGP (p<0.01 and CRP (p<0.05 was registered in the serums of AS patients. ESR was not significantly reduced. Conclusion. The research proved that α 1-acid glycoprotein, ceruloplasmine and C-reactive protein represent more sensitive inflammation markers as compared to erythrocyte sedimentation rate. The identification of acute phase reactants is important in the evaluation of dosed balneotherapy efficiency in the treatment of ankylosing spondylitis.

    Progranulin and C1q/TNF-related protein-3 (CTRP3) were recently discovered as novel adipokines which may link obesity with altered regulation of glucose metabolism, chronic inflammation and insulin resistance. We examined circulating progranulin and CTRP3 concentrations in 127 subjects with (n = 44) or without metabolic syndrome (n = 83). Furthermore, we evaluated the relationship of progranulin and CTRP3 levels with inflammatory markers and cardiometabolic risk factors, including high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), estimated glomerular filtration rate (eGFR), and adiponectin serum concentrations, as well as carotid intima-media thickness (CIMT). Circulating progranulin levels are significantly related with inflammatory markers, hsCRP (r = 0.30, P = 0.001) and IL-6 (r = 0.30, P = 0.001), whereas CTRP3 concentrations exhibit a significant association with cardiometabolic risk factors, including waist circumference (r = -0.21), diastolic blood pressure (r = -0.21), fasting glucose (r = -0.20), triglyceride (r = -0.34), total cholesterol (r = -0.25), eGFR (r = 0.39) and adiponectin (r = 0.26) levels. Serum progranulin concentrations were higher in patients with metabolic syndrome than those of the control group (199.55 [179.33, 215.53] vs. 185.10 [160.30, 204.90], P = 0.051) and the number of metabolic syndrome components had a significant positive correlation with progranulin levels (r = 0.227, P = 0.010). In multiple regression analysis, IL-6 and triglyceride levels were significant predictors of serum progranulin levels (R(2) = 0.251). Furthermore, serum progranulin level was an independent predictor for increased CIMT in subjects without metabolic syndrome after adjusting for other cardiovascular risk factors (R(2) = 0.365).

    Type 2 diabetes (T2D) may be caused by elevated oxidative stress, inflammation, and hyperglycemia. The phytochemicals in several herbal medicines are reported to effectively improve diabetes and to ameliorate diabetic complications. The aim of the present study was to determine the effects of cinnamon, cardamom, saffron, and ginger as supplementary remedies in T2D. This randomized controlled, clinical trial included 204 T2D patients. The participants were randomly assigned to four intervention groups receiving 3 glasses of black tea and either 3 g cardamom, or cinnamon, or ginger, or 1 g saffron and one control group which consumed only 3 tea glasses without any herbal medicine for 8 weeks. Markers of inflammation, oxidative stress, fasting blood sugar, lipid profile, and anthropometric measures were evaluated at baseline and after 8 weeks of intervention. After 8 weeks of intervention, cinnamon, cardamom, ginger, and saffron consumption had significant effects on total cholesterol, LDL, and HDL levels (p < 0.05) compared with controls. However, the herbal products did not have significant effects on measures of glycemic control, anthropometry, inflammation, and oxidative stress. In within-group comparisons only, cinnamon intake significantly decreased fasting blood sugar (FBS). The herbal remedies examined had significantly beneficial effects on cholesterol, but not on measures of glycemic control, oxidative stress, and inflammation. Based on the contradictory results reported in the literature, the effects of herbal medicine in diabetic patients should undergo further detailed investigation.

    The use of CEA as a prognostic and predictive marker in patients with lung cancer is widely debated. The aim of this review was to evaluate the results from studies made on this subject. Using the search words "CEA", "tumor markers in lung cancer", "prognostic significance", "diagnostic significance" and "predictive significance", a search was carried out on PubMed. Exclusion criteria was articles never published in English, articles before 1981 and articles evaluating tumor markers in lung cancer not involving CEA. Initially 217 articles were found, and 34 were left after selecting those relevant for the present study. Four of these included both Non-Small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC) patients, and 31 dealt solely with NSCLC patients. Regarding SCLC no studies showed that serum level of CEA was a prognostic marker for overall survival (OS). The use of CEA serum level as a prognostic marker in NSCLC was investigated in 23 studies and the use of CEA plasma level in two. In 18 (17 serum, 1 plasma) of these studies CEA was found to be a useful prognostic marker for either OS, recurrence after surgery or/and progression free survival (PFS) in NSCLC patients. Interestingly, an overweight of low stage (stage I-II) disease and adenocarcinoma (AC) patients were observed in this group. The remaining 7 studies (6 serum, 1 plasma) contained an overweight of patients with squamous carcinoma (SQ). One study found evidence for that a tumor marker index (TMI), based on preoperative CEA and CYFRA21-1 serum levels, is useful as a prognostic marker for OS in NSCLC. Six studies evaluated the use of CEA as a predictive marker for risk of recurrence and risk of death in NSCLC patients. Four of these studies found, that CEA was useful as a predictive marker for risk of recurrence and risk of death measured over time. No studies found CEA levels useful as a diagnostic marker for lung cancer. With regard to NSCLC the level of CEA measured in tumor tissue in

    Full Text Available Purpose and Methods: This is a series of three cases diagnosed with xanthogranulomatous inflammation of the female genital with emphasis on the etiology, clinical-pathologic features and biological behavior. Clinical, pathologic, radiologic and follow up data are reported.Results: The three cases of Xanthogranulomatous inflammation of the female genital tract are the followings: 1 one case affecting the endometrium, 2 one case affecting the fallopian tube, and 3 one case confined to the ovary. The patient's age was 37, 22 and 62 year-old, respectively. Histologic examination revealed extensive infiltration of foamy histiocytes admixed with variable amount of inflammatory cells. The later include plasma cells, lymphocytes, and occasional multinucleated giant cells. Immunohistochemistry showed positive staining for CD68, a histiocytic marker, in foamy histiocytes, CD3, a T cell marker, and CD20, a B cell marker, in the background lymphocytes. The plasma cells were polyclonal with expression of both κ and λ light chains.Conclusion: Xanthogranulomatous inflammation of the female genital tract is an unusual lesion, and clinically forms mass- like lesion in the pelvic cavity that invades the surrounding tissues, which may mimic the tumor clinically and by imaging.

    Full Text Available Metabolic syndrome (MS represents a cluster of physiological and anthropometric abnormalities. The purpose of this study was to investigate the relationships between the levels of inflammation, adiponectin, and oxidative stress in subjects with MS. The inclusion criteria for MS, according to the Taiwan Bureau of Health Promotion, Department of Health, were applied to the case group (n = 72. The control group (n = 105 comprised healthy individuals with normal blood biochemical values. The levels of inflammatory markers [high sensitivity C-reactive protein (hs-CRP and interleukin-6 (IL-6, adiponectin, an oxidative stress marker (malondialdehyde, and antioxidant enzymes activities [catalase (CAT, superoxide dismutase (SOD, and glutathione peroxidase (GPx] were measured. Subjects with MS had significantly higher concentrations of inflammatory markers and lower adiponectin level, and lower antioxidant enzymes activities than the control subjects. The levels of inflammatory markers and adiponectin were significantly correlated with the components of MS. The level of hs-CRP was significantly correlated with the oxidative stress marker. The IL-6 level was significantly correlated with the SOD and GPx activities, and the adiponectin level was significantly correlated with the GPx activity. A higher level of hs-CRP (≥1.00 mg/L, or IL-6 (≥1.50 pg/mL or a lower level of adiponectin (<7.90 µg/mL were associated with a significantly greater risk of MS. In conclusion, subjects suffering from MS may have a higher inflammation status and a higher level of oxidative stress. A higher inflammation status was significantly correlated with decreases in the levels of antioxidant enzymes and adiponectin and an increase in the risk of MS.

    Oxidant stress (OS) and inflammation increase in normal aging and in chronic kidney disease (CKD), as observed in human and animal studies. In cross-sectional studies of the US population, these changes are associated with a decrease in renal function, which is exhibited by a significant proportion of the population. However, since many normal adults have intact renal function, and longitudinal studies show that some persons maintain normal renal function with age, the link between OS, inflammation, and renal decline is not clear. In aging mice, greater oxidant intake is associated with increased age-related CKD and mortality, which suggests that interventions that reduce OS and inflammation may be beneficial for older individuals. Both OS and inflammation can be readily lowered in normal subjects and patients with CKD stage 3-4 by a simple dietary modification that lowers intake and results in reduced serum and tissue levels of advanced glycation end products. Diabetic patients, including those with microalbuminuria, have a decreased ability to metabolize and excrete oxidants prior to observable changes in serum creatinine. Thus, OS and inflammation may occur in the diabetic kidney at an early time. We review the evidence that oxidants in the diet directly lead to increased serum levels of OS and inflammatory mediators in normal aging and in CKD. We also discuss a simple dietary intervention that helps reduce OS and inflammation, an important and achievable therapeutic goal for patients with CKD and aging individuals with reduced renal function.

    Pancreatic ductal adenocarcinoma is one of the most difficult malignancies to diagnose and treat. The aim of this article is to review how tumor markers can aid the diagnosis and management of patients with this malignancy. The most widely used and best validated marker for pancreatic cancer is CA 19-9. Inadequate sensitivity and specificity limit the use of CA 19-9 in the early diagnosis of pancreatic cancer. In non-jaundiced patients, however, CA 19-9 may complement other diagnostic procedures. In patients with resectable pancreatic cancer, presurgical and postresection CA 19-9 levels correlate with overall survival. In advanced disease, elevated pretreatment levels of CA 19-9 are associated with adverse patient outcome and thus may be combined with other factors for risk stratification. Most, but not all, reports indicate that serial levels of CA 19-9 correlate with response to systemic therapy. Use of CA 19-9 kinetics in conjunction with imaging is therefore recommended in monitoring therapy. Although several potential serum and tissue markers for pancreatic cancer are currently undergoing evaluation, none are sufficiently validated for routine clinical use. CA 19-9 thus remains the serum pancreatic cancer marker against which new markers for this malignancy should be judged.

    There is convincing evidence that consumption of fish and fish oil rich in long-chain (LC) n-3 PUFA (n-3 LCPUFA), EPA (20 : 5n-3) and DHA (22 : 6n-3) reduce the risk of CHD. The aim of the present study was to investigate whether n-3 LCPUFA-enriched food products provide similar beneficial effects as fish oil with regard to incorporation into plasma lipids and effects on cardiovascular risk markers. A parallel 7-week intervention trial was performed where 159 healthy men and women were randomised to consume either 34 g fish pâté (n 44), 500 ml fruit juice (n 38) or three capsules of concentrated fish oil (n 40), all contributing to a daily intake of approximately 1 g EPA and DHA. A fourth group did not receive any supplementation or food product and served as controls (n 37). Plasma fatty acid composition, serum lipids, and markers of inflammation and oxidative stress were measured. Compared with the control group, plasma n-3 LCPUFA and EPA:arachidonic acid ratio increased equally in all intervention groups. However, no significant changes in blood lipids and markers of inflammation and oxidative stress were observed. In conclusion, enriched fish pâté and fruit juice represent suitable delivery systems for n-3 LCPUFA. However, although the dose given is known to reduce the risk of CVD, no significant changes were observed on cardiovascular risk markers in this healthy population.

    Increasing evidence has established causative links between obesity, chronic inflammation and insulin resistance; the core pathophysiological feature in type 2 diabetes mellitus. This study was designed to examine whether the combination of L-cysteine and metformin would provide additional benefits in reducing oxidative stress, inflammation and insulin resistance in streptozotocin-induced type 2 diabetes in rats. Male Wistar rats were fed a high-fat diet (HFD) for 8 weeks to induce insulin resistance after which they were rendered diabetic with low-dose streptozotocin. Diabetic rats were treated with metformin (300 mg/kg/day), L-cysteine (300 mg/kg/day) and their combination along with HFD for another 2 weeks. Control rats were fed normal rat chow throughout the experiment. At the end of treatment, fasting blood glucose, fasting serum insulin, homeostasis model assessment-insulin resistance index (HOMA-IR) and serum free fatty acids (FFAs) were measured. Serum levels of the inflammatory markers; monocyte chemoattractant protein-1 (MCP-1), C-reactive protein (CRP) and nitrite/nitrate were also determined. The liver was isolated and used for determination of malondialdehyde (MDA), reduced glutathione (GSH), caspase-3 and cytochrome c levels. The hypoglycemic effect of the combination therapy exceeded that of metformin and L-cysteine monotherapies with more improvement in insulin resistance. All treated groups exhibited significant reductions in serum FFAs, oxidative stress and inflammatory parameters, caspase-3 and cytochrome c levels compared to untreated diabetic rats with the highest improvement observed in the combination group. In conclusion, the present results clearly suggest that L-cysteine can be strongly considered as an adjunct to metformin in management of type 2 diabetes. © 2013 Elsevier B.V. All rights reserved.

    The inflammatory response is integral to maintaining health, by functioning to resist microbial infection and repair tissue damage. Large numbers of neutrophils are recruited to inflammatory sites to neutralise invading bacteria through phagocytosis and the release of proteases and reactive oxygen species into the extracellular environment. Removal of the original inflammatory stimulus must be accompanied by resolution of the inflammatory response, including neutrophil clearance, to prevent inadvertent tissue damage. Neutrophil apoptosis and its temporary inhibition by survival signals provides a target for anti-inflammatory therapeutics, making it essential to better understand this process. GM-CSF, a neutrophil survival factor, causes a significant increase in mRNA levels for the known anti-apoptotic protein Serum and Glucocorticoid Regulated Kinase 1 (SGK1). We have characterised the expression patterns and regulation of SGK family members in human neutrophils, and shown that inhibition of SGK activity completely abrogates the anti-apoptotic effect of GM-CSF. Using a transgenic zebrafish model, we have disrupted sgk1 gene function and shown this specifically delays inflammation resolution, without altering neutrophil recruitment to inflammatory sites in vivo. These data suggest SGK1 plays a key role in regulating neutrophil survival signalling, and thus may prove a valuable therapeutic target for the treatment of inflammatory disease. PMID:24431232

    Full Text Available Background: Neutrophil-to-lymphocyte ratio (NLR was widely studied as a prognostic marker in various medical and surgical specialties, but its significance in nephrology is not yet established. Objective: We evaluated its accuracy as an inflammation biomarker in a dialysis population. Design setting: Single-center retrospective study. Patients: The records of all 550 patients who were treated with hemodialysis (HD or peritoneal dialysis (PD from September 2008 to March 2011 were included. Measurements: NLR was calculated from the monthly complete blood count. Methods: Association between NLR and markers of inflammation (C-reactive protein [CRP], serum albumin, and erythropoietin resistance index [ERI] was measured using Spearman coefficient. Results: In total, 120 patients were eligible for the correlation analyses. We found a positive correlation between NLR and CRP (all patients: r = 0.45, P < .001; HD: r = 0.47, P < .001; PD: r = 0.48, P = .13. NLR and albumin were inversely correlated ( r = −0.51, P < .001. Finally, high NLR was associated with a nonsignificant increased ERI, but we have not demonstrated a direct correlation. Limitations: CRP and albumin are not measured routinely and were ordered for a specific clinical reason leading to an indication bias. Also, no relationship with clinical outcome was established. Conclusions: NLR seems to be a good inflammatory biomarker in dialysis in addition to being easily available. However, controlled studies should be conducted to properly assess and validate NLR levels that would be clinically significant and relevant, as well as its prognostic significance and utility in a clinical setting.

    Full Text Available Background: Despite a high prevalence of endometriosis, there still exist many challenges indiagnosing the disease. This study aims to evaluate non-invasive and practical diagnostic methodsby measuring serum and peritoneal fluid CA 125 levels in patients with endometriosis. A secondaryaim is to determine the correlation between these markers with the stage of disease as well as therelationship of the two markers with each other.Materials and Methods: This is a cross-sectional study of 60 women who underwent laparoscopyfor benign conditions. Based on laparoscopic findings and biopsy results, patients were divided to twogroups; one group included patients with pelvic endometriosis (35 patients and the second enrolledpatients free from endometriosis (25 patients. Serum and peritoneal fluid specimens were provided at thetime of laparoscopy and CA125 levels were then assessed by electrochemiluminescence immunoassay.Results: Mean serum and peritoneal fluid CA125 levels were significantly higher in women withendometriosis as compared to the control group (26.42 ± 24.34 IU/ml versus 12.64 ± 6.87 IU/mlin serum and 2203.54 + 993.19 IU/ml versus 1583.42 ± 912.51 IU/ml in peritoneal fluid, p<0.05.CA 125 levels also varied proportionally with the stage of endometriosis; but showed a significantdifference only in higher stages of the disease, both in serum and peritoneal fluid. We calculatedthe cut-off value suggesting a diagnosis of pelvic endometriosis as 14.70 IU/ml for serum and1286.5 IU/ml for peritoneal fluid CA125. A linear correlation between CA 125 levels in serum andperitoneal fluid in patients with pelvic endometriosis has also been observed.Conclusion: Serum and peritoneal fluid CA 125 levels are simple and non-surgical tools fordiagnosing and staging pelvic endometriosis. These markers are of greater diagnostic value inhigher stages of the disease.
