    We here investigated whether experimental gingivitis enhances systemic markers of inflammation which are also known as surrogate markers of atherosclerotic plaque development. Gingivitis is a low-level oral infection induced by bacterial deposits with a high prevalence within Western populations. A potential link between the more severe oral disease periodontitis and cardiovascular disease has already been shown. 37 non-smoking young volunteers with no inflammatory disease or any cardiovascular risk factors participated in this single-subject interventional study with an intra-individual control. Intentionally experimental oral inflammation was induced by the interruption of oral hygiene for 21 days, followed by a 21-days resolving phase after reinitiation of oral hygiene. Primary outcome measures at baseline, day 21 and 42 were concentrations of hsCRP, IL-6, and MCP-1, as well as adhesion capacity and oxLDL uptake of isolated blood monocytes. The partial cessation of oral hygiene procedures was followed by the significant increase of gingival bleeding (34.0%, Pgingivitis. Bacterial-induced gingival low-level inflammation induced a systemic increase in inflammatory markers. Dental hygiene almost completely reversed this experimental inflammatory process, suggesting that appropriate dental prophylaxis may also limit systemic markers of inflammation in subjects with natural gingivitis.

    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.

    Systemic lupus erythematosus (SLE) is an autoimmune disease that involves multiple organs and is characterized by persistent systemic inflammation. Among the effects of inflammatory mediators, the induction of matrix metalloproteinases-2 and -9 (MMP-2 and MMP-9) and oxidative stress has been demonstrated to be important in the development of SLE. In this study, the possible association between MMP-9 and MMP-2 functional promoter polymorphism, stress, and inflammatory markers with development of severe cardiovascular disease (CVD), high blood pressure (HBP), and lupus nephropathy (LN) in SLE patients was investigated. The present case-control study consisted of 109 SLE patients with and without CVD, HBP and LN and 101 gender- and age-matched unrelated healthy controls from a population in western Iran. MMP-2 -G1575A and MMP-9 -C1562T polymorphisms were detected by PCR-RFLP, serum MMP-2 and MMP-9, neopterin, malondialdehyde (MDA) and lipid levels were determined by ELISA, HPLC and enzyme assay, respectively. We found that MMP-9 -C1562 T and MMP-2 -G1575A alleles act synergistically to increase the risk of SLE by 2.98 times (p = 0.015). Findings of this study also demonstrated that there is a significant increase in the serum levels of MMP-2, neopterin and MDA and a significant decrease in serum level of MMP-9 in the presence of MMP-9-C1562 T and MMP-2 -G1575A alleles in SLE patients compared to controls. Further, SLE patients with MMP-9 (C/T + T/T) genotype had significantly higher serum concentrations of MMP-2, neopterin, MDA and LDL-C, but lower serum MMP-9 and HDL-C levels than corresponding members of the control group. MMP-9 (C/T + T/T) genotype increased risk of hypertension in SLE patients 2.71-fold. This study for the first time not only suggests that MMP-9 -C1562 T and MMP-2 -G1575A alleles synergistically increase the risk of SLE but also high serum levels of MDA, neopterin, and circulatory levels of MMP-2 and lower MMP-9 in SLE patients.

    Prostate cancer is the most common cancer in Western society males, with incidence rates predicted to rise with global aging. Etiology of prostate cancer is however poorly understood, while current diagnostic tools can be invasive (digital rectal exam or biopsy) and/or lack specificity for the disease (prostate-specific antigen (PSA) testing). Substantial histological, epidemiological and molecular genetic evidence indicates that inflammation is important in prostate cancer pathogenesis. In this review, we summarize the current status of inflammatory genetic markers influencing susceptibility to prostate cancer. The focus will be on inflammatory cytokines regulating T-helper cell and chemokine homeostasis, together with the Toll-like receptors as key players in the host innate immune system. Although association studies indicating a genetic basis for prostate cancer are presently limited mainly due to lack of replication, larger and more ethnically and clinically defined study populations may help elucidate the true contribution of inflammatory gene variants to prostate cancer risk.

    Ciguatoxins are extremely potent neurotoxins, produced by tropical marine dinoflagellates, that persistently enter into our food web. Over 100,000 people annually experience acute ciguatera poisoning from consuming toxic fish. Roughly 5% of these victims will develop chronic ciguatera (CC), a widespread, multisymptom, multisystem, chronic illness that can last tens of years. CC is marked by disproportionate disability and non-specific refractory symptoms such as fatigue, cognitive deficits and pain, and is suggestive of other illnesses. Its unknown pathophysiology makes both diagnosis and treatment difficult. We wanted to compare objective parameters of visual contrast sensitivity testing, measures of innate immune response and genetic markers in cases to controls to assess the potential for the presence of persistent inflammatory parameters that are demonstrated in other biotoxin associated illnesses at a single specialty clinic. Using 59 CC cases and 59 controls we present in retrospective review, in all cases, abnormalities in immune responses paralleling the chronic systemic inflammatory response syndrome seen in several other chronic diseases. This study defines a preliminary case definition using medical history, total symptoms, visual contrast sensitivity, HLA DR genotype analysis, reduction of regulatory neuropeptides VIP and MSH, and multiple measures of inflammatory immune response, especially C4a and TGFβ1, thereby providing a basis for identification and targeted therapy. CC provides a model for chronic human illness associated with initiation of inflammatory responses by biologically produced neurotoxins. Copyright © 2010 Elsevier Inc. All rights reserved.

    Background: Periodontitis is a local inflammatory process mediating destruction of periodontium triggered by bacterial insult leading to systemic inflammatory mayhem in the host. Epidemiologically, it has been modestly associated with cardiovascular diseases (CVD) with elevated acute-phase reactant C-reactive protein (CRP) and rheological variables such as total leukocyte count and differential leukocyte count (TLC and DLC), which are potential predictors of CVD. Aim: The aim of this study was to investigate the serum CRP level, leukocyte count in chronic periodontitis patients and their relation to the severity of chronic periodontitis. Subjects and Methods: This cross-sectional study comprised 30 subjects, of which 20 were diagnosed as chronic periodontitis based on the Gingival index, probing depth and clinical attachment levels and 10 healthy subjects as controls. Following, which peripheral blood samples were drawn and serum CRP, TLC and DLC were quantified using the turbidimetric immunoassay. Data was analyzed using Intercooled Stata 9.2 version, (Stata corporation, LP, USA) ANOVA, Mann Whitney U test and Newman-Keuls post hoc procedures. P values less than) 0.05 were considered as significant Results: The mean serum CRP levels were statistically significant (P periodontitis subjects when compared with healthy controls. Leukocytes were significantly elevated in severe periodontitis compared with moderate periodontitis and controls; this finding was primarily explained by the increase in number of neutrophils. Conclusion: The increased serum CRP levels and neutrophils in chronic periodontitis subjects suggest an addition to the inflammatory burden of the individual potentially striking toward an increasing risk for cardiovascular events. Further research is needed to determine the specificity of these markers and their role in the inflammatory burden of one's systemic health. PMID:24971214

    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.

    Tannerella forsythia is a Gram-negative anaerobic organism that inhabits the subgingival cavity and initiates connective tissue destruction and alveolar bone resorption in periodontal disease (PD). PD is a chronic immunoinflammatory disease and has been linked to several systemic diseases including atherosclerosis. This study evaluated the effects of a chronic oral infection with T. forsythia ATCC 43037 on the induction of PD, inflammatory markers and atherosclerosis risk factors in hyperlipidemic ApoE(null) mice. Mice were orally infected for 12 and 24 weeks prior to euthanasia. Bacterial colonization of the oral cavity and bacteremia was confirmed via isolation of genomic DNA from oral plaque and tissues. Oral infection elicited significantly elevated levels of serum IgG and IgM antibodies and alveolar bone resorption compared to control mice. Tannerella forsythia-infected mice had increased serum amyloid A, and significantly reduced serum nitric oxide when compared to controls. Tannerella forsythia chronic infection also significantly increased serum lipoproteins suggesting altered cholesterol metabolism and potential for aortic inflammation. Despite enhanced acute phase reactants and altered lipid profiles, T. forsythia infection was associated with decreased aortic plaque. This study investigates the potential of a known periodontal bacterial pathogen found in atherosclerotic plaque in humans to accelerate atherosclerosis in hyperlipdemic mice. © FEMS 2015.

    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.

    Autonomic nervous system (ANS) imbalance has been cross-sectionally associated with inflammatory processes. Longitudinal studies are needed to shed light on the nature of this relationship. We examined cross-sectional and bidirectional prospective associations between cardiac autonomic measures and inflammatory markers. Analyses were conducted with baseline (n = 2823), 2-year (n = 2099), and 6-year (n = 1774) data from the Netherlands Study of Depression and Anxiety. To compare the pattern of results, prospective analyses with ANS (during sleep, leisure time, and work) and inflammation were conducted in two data sets from the Netherlands Twin Register measured for 4.9 years (n = 356) and 5.4 years (n = 472). Autonomic nervous system measures were heart rate (HR) and respiratory sinus arrhythmia (RSA). Inflammatory markers were C-reactive protein (CRP) and interleukin (IL)-6. The Netherlands Study of Depression and Anxiety results showed that higher HR and lower RSA were cross-sectionally significantly associated with higher inflammatory levels. Higher HR predicted higher levels of CRP (B = .065, p < .001) and IL-6 (B = .036, p = .014) at follow-up. Higher CRP levels predicted lower RSA (B = -.024, p = .048) at follow-up. The Netherlands Twin Register results confirmed that higher HR was associated with higher CRP and IL-6 levels 4.9 years later. Higher IL-6 levels predicted higher HR and lower RSA at follow-up. Autonomic imbalance is associated with higher levels of inflammation. Independent data from two studies converge in evidence that higher HR predicts subsequent higher levels of CRP and IL-6. Inflammatory markers may also predict future ANS activity, but evidence for this was less consistent.

    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.

    2011-01-01

    Up to now there is no established parameters for the follow-up of delayed radiation injuries. Late toxicity is generally irreversible and can have devastating effects on quality of life of people exposed either accidentally or during therapeutic radiation treatments. Histologically, late manifestations of radiation damage include fibrosis, necrosis, atrophy and vascular lesions. Although many etiologies have been suggested regarding these late toxicities, persistent inflammation has been described as playing a key role. The recruitment of leukocytes from circulating blood is decisive in the inflammatory reaction. All the steps in the recruitment cascade are orchestrated by cell-adhesion molecules (CAMs) on both leukocytes and endothelial cells, and different subsets of CAMs are responsible for different steps in extravasation. A link between radiation –induced inflammatory processes and alterations in T-cell immunity are still demonstrable in the blood of A-bomb survivors. The following study was conducted to examine the response of the immune system in the inflammatory reactions in patients with late skin injuries after radiotherapy or interventional fluoroscopy procedures. The expression of adhesion molecules ICAM1 and β1-integrin on granulocytes and lymphocytes, as well as changes in subpopulations of T lymphocytes and the level of C-reactive protein, a well- studied inflammatory marker were evaluated.

    Many psychiatric disorders, like schizophrenia, affective disorders, addictions and different forms of dementia are associated with sleep disturbances. In the etiology and course of those diseases inflammatory processes are regarded to be an increasingly important factor. They are also a frequently discussed element of the pathology of sleep. In this literature review reports on correlations between poor sleep and inflammatory responses in various psychiatric conditions are discussed. The link between schizophrenia, affective disorders and inflammatory cytokines is a complex phenomenon, which has been already confirmed in a number of studies. However, the presence of sleep deficits in those conditions, being a common symptom of depression and psychoses, can be an additional factor having a considerable impact on the immunological processes in mental illnesses. In the analyzed data, a number of studies are presented describing the role of inflammatory markers in sleep disturbances and psychopathological symptoms of affective, psychotic, neurogenerative and other disorders. Also attention is drawn to possible implications for their treatment. Efforts to use, e.g., anti-inflammatory agents in psychiatry in the context of their impact on sleep are reported. The aspect of inflammatory markers in the role of sleep deprivation as the treatment method in major depressive disorder is also discussed. A general conclusion is drawn that the improvement of sleep quality plays a crucial role in the care for psychiatric patients.

    Childhood obesity has grown at an alarming rate, and is associated with metabolic disturbances that determine a higher risk of type 2 diabetes (T2DM) and atherosclerotic cardiovascular disease (CVD) in adulthood. These disturbances may arise at a very early age in obese children. These metabolic disturbances may be associated with insulin resistance (IR), a systemic low-grade inflammatory state and endothelial dysfunction. Thus it was aimed to determine the concentration levels of C-reactive protein (CRP), interleukin 6 (IL-6) and soluble intercellular adhesion molecule-1 (sICAM-1) in obese pre-pubertal children, and their possible relation with metabolic syndrome. For this reason weight (kg), height (m), body mass index (BMI, kg/m 2 ), systolic and diastolic blood pressure (SBP and DBP, mm Hg), fasting plasma glucose (FPG), lipid profile [total cholesterol (TC), cholesterol fractions HDL-C and LDL-C, and triglycerides (TGs)], fasting insulin (FI), fasting glucose ,HOMA-IR =fasting insulin (μU/ml) blood glucose (mg/dl)/405, CRP, IL-6 and sICAM-1 were analyzed in 30 obese and 15 non obese children. The results obtained displayed significantly elevated values for insulin (ρ= 0.001), homeostasis model assessment for IR (HOMA-IR, ρ 0.001), CRP (ρ< 0.001), IL-6 (ρ= 0.001) and sICAM-1 levels (ρ0.001) in obese children. Nonsignificant differences were found in fasting glucose. Moreover, sICAM- 1 showed a positive correlation with insulin, HOMA-IR, CRP and IL-6 (ρ= 0.042), (ρ= 0.0009), (ρ0.054) and (ρ= 0.026) respectively. It thus could be concluded that prepubertal obese children displayed alterations indicative of endothelial dysfunction, insulin resistance, and inflammatory state which may foreshadow an increased burden of CVD and T2DM in the future. Thus, early identification of the inflammatory and endothelial bio markers in obese children may assist in early interference to prevent progression and complications of type 2 DM and CVD. Moreover, longitudinal

    Epidemiological studies have demonstrated the beneficial effect of plant-derived food intake in reducing the risk of cardiovascular disease (CVD). The potential bioactivity of cocoa and its polyphenolic components in modulating cardiovascular health is now being studied worldwide and continues to grow at a rapid pace. In fact, the high polyphenol content of cocoa is of particular interest from the nutritional and pharmacological viewpoints. Cocoa polyphenols are shown to possess a range of cardiovascular-protective properties, and can play a meaningful role through modulating different inflammatory markers involved in atherosclerosis. Accumulated evidence on related anti-inflammatory effects of cocoa polyphenols is summarized in the present review. PMID:24566441

    Childhood maltreatment (CM) has been associated with several diseases in adult life, including diabetes, obesity and mental disorders. Inflammatory conditions have been postulated as possible mediators of this relationship. The aim was to conduct a systematic review regarding the association between CM and inflammatory markers in adulthood. A literature search of the PubMed, ISI, EMBASE and PsychINFO databases was conducted. The key terms used were as follows: 'Child Maltreatment', 'Childhood Trauma', 'Early Life Stress', 'Psychological Stress', 'Emotional Stress', 'Child Abuse' and 'Child Neglect'. They were cross-referenced separately with the terms: 'C-reactive Protein (CRP)', 'Tumor Necrosis Factor', 'Cytokine', 'Interleukin', 'Inflammatory' and 'Inflammation'. Twenty articles remained in the review after exclusion criteria were applied. Studies showed that a history of CM was associated with increased levels of CRP, fibrinogen and proinflammatory cytokines. Increased levels of circulating CRP in individuals with a history of CM were the most robust finding among the studies. Data about anti-inflammatory mediators are still few and inconsistent. Childhood maltreatment is associated with a chronic inflammatory state independent of clinical comorbidities. However, studies are heterogeneous regarding CM assessment and definition. Important methodological improvements are needed to better understand the potential impact of CM on inflammatory response. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  12. Inflammatory cardiovascular risk markers in obstructive sleep apnoea syndrome.

    Obstructive sleep apnoea syndrome (OSAS) represents a highly prevalent disease and is recognized as a major public health burden. Large-scale epidemiological studies have demonstrated an independent relationship between OSAS and various cardiovascular disorders. The pathogenesis of cardiovascular complications in OSAS is not completely understood, but given the complexity of the disorder, a multifactorial etiology is likely. Inflammatory processes have emerged as critical in the pathogenesis of atherosclerosis in general and they mediate many of the stages of atheroma formation. Circulating levels of several markers of inflammation have been associated with future cardiovascular risk. These markers include cell adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) and selectins, cytokines such as tumour necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6), chemokines such as IL-8, and C-reactive protein (CRP). There is increasing evidence that inflammatory processes also play a central role in the cardiovascular pathophysiology of OSAS. This is supported by cell culture and animal studies identifying a preferential activation of inflammatory pathways by intermittent hypoxia (IH), the hallmark of OSAS. A number of studies have selectively examined the expression of inflammatory factors in OSAS patients with different conclusions. These different findings may have been contributed to by a number of methodological factors such as small subject numbers, inadequately matched study populations, particularly in terms of body mass index (BMI), and inclusion of patients with pre-existing cardiovascular or metabolic diseases. This review will focus on the potential role of various inflammatory markers in OSAS with a critical analysis of the current literature.

    Full Text Available Depression has been shown to be associated with systemic inflammatory activity and the mode of action of several antidepressants appears to involve immunomodulation. Effects on immune system activity have also recently been observed in correlation with therapeutic response to mirtazapine in cardiac patients with depression, but no study has yet examined these effects in otherwise physically healthy depressed patients treated with mirtazapine. This report describes an association between a clinical antidepressant response and a decrease in markers of systemic inflammation observed during pharmacotherapy with mirtazapine in a severely depressed but physically well patient. This observation adds to the evidence that changes in inflammatory responses may be implicated in the mode of action of antidepressants. Further studies of antidepressant responses to mirtazapine and levels of inflammatory markers in depressed patients without medical comorbidity can help elucidate the role of the immune system in the pathophysiology of depression, and hence contribute to the development of novel antidepressant therapies.

    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.

    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.

    Red blood cell (RBC) transfusion is a life-saving treatment for several pathologies. RBCs for transfusion are stored refrigerated in a preservative solution, which extends their shelf-life for up to 42 days. During storage, the RBCs endure abundant physicochemical changes, named RBC storage lesions, which affect the overall quality standard, the functional integrity and in vivo survival of the transfused RBCs. Some of the changes occurring in the early stages of the storage period (for approximately two weeks) are reversible but become irreversible later on as the storage is extended. In this review, we aim to decipher the duration of RBC storage and inflammatory marker generation. This phenomenon is included as one of the causes of transfusion-related immunomodulation (TRIM), an emerging concept developed to potentially elucidate numerous clinical observations that suggest that RBC transfusion is associated with increased inflammatory events or effects with clinical consequence.

    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.

    Lack of social integration predicts coronary heart disease mortality in prospective studies; however, the biological pathways that may be responsible are poorly understood. The specific aims of this study were to examine whether social networks are associated with serum concentrations of the inflammatory markers interleukin-6 (IL-6), C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (sICAM-1) and monocyte chemoattractant protein-1 (MCP-1). Participants in the Framingham Study attending examinations from 1998 to 2001 (n=3267) were eligible for inclusion in the study. Social networks were assessed using the Berkman-Syme Social Network Index (SNI). Concentrations of IL-6, CRP, sICAM-1 and MCP-1 were measured in fasting serum samples. Multivariable linear regression analyses were used to assess the association of social networks with inflammatory markers adjusting for potential confounders including age, smoking, blood pressure, total:HDL cholesterol ratio, body mass index, lipid-lowering and antihypertensive medication, diabetes, cardiovascular disease, depression and socioeconomic status. Results found that the SNI was significantly inversely associated with IL-6 in men (p=0.03) after adjusting for potential confounders. In age-adjusted analyses, social networks also were significantly inversely associated with IL-6 for women (p=0.03) and were marginally to modestly associated with CRP and sICAM-1 for men (p=0.08 and 0.02, respectively), but these associations were not significant in the multivariate analyses. In conclusion, social networks were found to be inversely associated with interleukin-6 levels in men. The possibility that inflammatory markers may be potential mediators between social integration and coronary heart disease merits further investigation.

    The present analysis investigated the effect of soya foods on serum levels of six inflammatory markers, leptin, adiponectin, monocyte attractant protein 1 (MCP-1), macrophage inflammatory protein-1b (MIP-1b), IL-6 and C-reactive protein (CRP), and their relationship with BMI and lifetime soya intake. We randomised twenty-four men to a high- (two daily servings with 30-35 mg isoflavones per serving) or a low-soya diet for 3 months. After a 1-month washout period, the men crossed over to the other treatment. We used a multiplex bead immunoassay to measure leptin, adiponectin, MCP-1 and MIP-1b and ELISA assays for IL-6 and CRP. The statistical analysis applied mixed models that incorporated the four repeated measurements. The men had a mean age of 58.7 (sd 7.2) years and a mean BMI of 28.4 (sd 4.9) kg/m2. We observed no significant intervention effect of the soya treatment on any of the six markers. After adjustment for age and ethnicity, highly significant associations of BMI and body weight with leptin and MCP-1 emerged. Men with high soya intake early in life also had higher levels of leptin and MCP-1, whereas no association was seen for soya intake during adulthood. MIP-1b, adiponectin, IL-6 and CRP were not related to BMI, body weight or soya intake at any time in life. No intervention effect of soya foods on markers of inflammation was observed in this small study, but adiposity and early-life soya intake were related to higher leptin and MCP-1 levels.

    The spectrum of serological markers associated with inflammatory bowel disease (IBD) is rapidly growing. Due to frequently delayed or missed diagnoses, the application of non-invasive diagnostic tests for IBD, as well as differentiation between ulcerative colitis (UC) and Crohn’s disease (CD), would be useful in the pediatric population. In addition, the combination of pancreatic autoantibodies and antibodies against Saccharomyces cerevisiae antibodies/perinuclear cytoplasmic antibody (pANCA) improved the sensitivity of serological markers in pediatric patients with CD and UC. Some studies suggested that age-associated differences in the patterns of antibodies may be present, particularly in the youngest children. In CD, most patients develop stricturing or perforating complications, and a significant number of patients undergo surgery during the disease course. Based on recent knowledge, serum antibodies are qualitatively and quantitatively associated with complicated CD behavior and CD-related surgery. Pediatric UC is characterized by extensive colitis and a high rate of colectomy. In patients with UC, high levels of anti-CBir1 and pANCA are associated with the development of pouchitis after ileal pouch-anal anastomosis. Thus, serologic markers for IBD can be applied to stratify IBD patients into more homogeneous subgroups with respect to disease progression. In conclusion, identification of patients at an increased risk of rapid disease progression is of great interest, as the application of early and more aggressive pharmaceutical intervention could have the potential to alter the natural history of IBD, and reduce complications and hospitalizations.

    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.

    Full Text Available The aim was to assess inflammatory markers among adults and adolescents in relation to the adherence to the Mediterranean diet. A random sample (219 males and 379 females of the Balearic Islands population (12–65 years was anthropometrically measured and provided a blood sample to determine biomarkers of inflammation. Dietary habits were assessed and the adherence to the Mediterranean dietary pattern calculated. The prevalence of metabolic syndrome increased with age in both sexes. The adherence to the Mediterranean diet in adolescent males was 51.3% and 45.7% in adults, whereas in females 53.1% and 44.3%, respectively. In males, higher adherence to the Mediterranean diet was associated with higher levels of adiponectin and lower levels of leptin, tumor necrosis factor alpha (TNF-α, plasminogen activator inhibitor 1 (PAI-1 and high-sensitivity C-reactive protein (hs-CRP in adults, but not in young subjects. In females, higher adherence was associated with lower levels of leptin in the young group, PAI-1 in adults and hs-CRP in both groups. With increasing age in both sexes, metabolic syndrome increases, but the adherence to the Mediterranean diet decreases. Low adherence to the Mediterranean dietary pattern (MDP is directly associated with a worse profile of plasmatic inflammation markers.

    2018-01-01

    Full Text Available Introduction: Chronic obstructive pulmonary disease (COPD is a common preventable and treatable disease characterized by progressive airflow limitation and associated with enhanced chronic inflammatory response of the airways to a variety of noxious stimuli. The current concept of COPD, however, extends beyond the respiratory system to include a variety of extrapulmonary manifestations which includes raised inflammatory markers. Methods: This was a single, center observational open-labeled case–controlled study which included fifty patients of diagnosed COPD and 50 age- and gender-matched controls. All patients were evaluated by detailed history taking, pulmonary function test, 6-min walk test, and calculation of BODE scores. Levels of serum inflammatory markers such as cortisol, tumor necrosis factor alpha, interleukin-6 (IL-6, lactate dehydrogenase, and C-reactive protein were estimated using standard quality equipments. Observations: Majority of the patients in the study and control groups were males and were aged above 40 years. Thirty-eight of the fifty COPD patients had BODE scores of more than 3. All the studied inflammatory markers were significantly higher in the COPD group as compared to the control group. Of all the studied markers, only IL-6 showed a significant correlation with BODE index, i.e., higher IL-6 values were associated with higher BODE scores. No correlation was seen between the other markers and BODE scores. Conclusions: Our data suggest that IL-6 is a biomarker that correlates with BODE score. IL-6 as a target for therapy in COPD needs to be further studied. Follow-up studies are needed to validate findings.

Several recent publications have highlighted its potential role in the functioning of the immune system. The overall objective of this study was to look into possible correlations between levels of vitamin D and inflammatory markers in sera of healthy adult women. These markers included proinflammatory cytokines (interleukin [IL]-1β, IL-6, IL-8, IL-17, interferon [IFN]-γ, and tumor necrosis factor [TNF]-α, anti-inflammatory cytokines (IL-4, IL-10, and IL-13, as well as C-reactive protein (CRP as a general indicator of inflammation. Methods: Venous blood samples were collected from 118 healthy adult women and serum levels of vitamin D, CRP, proinflammatory cytokines (IL-1β, IL-6, IL-8, IL-17, IFN-γ, and TNF-α, and anti-inflammatory cytokines (IL-4, IL-10, and IL-13 were measured. Results: There were no significant direct correlations between serum levels of vitamin D and any of the inflammatory markers measured. However, subjects with deficient levels of vitamin D and high CRP produced significantly higher levels of the proinflammatory cytokines (TNF-α and IL-8 as compared to subjects with low CRP levels with nondeficient and deficient levels of vitamin D. Further, the anti-inflammatory/proinflammatory ratios suggest a role of vitamin D in maintaining an anti-inflammatory environment at low levels of CRP, an association that is weaker at high CRP levels in subjects with subclinical inflammatory situations. Conclusion: These data point to a

    Objectives: To determine whether the mean platelet volume (MPV) and MPV/platelet (PLT) values can be used in the study of sepsis and systemic inflammatory response syndrome (SIRS). Methods: In this retrospective case-controlled study, 69 sepsis, 69 SIRS patients, and 72 control group who were treated in the years 2012-2013 were reviewed, and both the MPV and MPV/PLT rates were evaluated in all groups at Kahramanmaras Sutcu Imam University Intensive Care Unit, Kahramanmaras, Turkey. Results: Statistically significant difference was found between sepsis, SIRS, and control groups when comparing the MPV and MPV/PLT ratio (p0.05). Mean platelet volume values for sepsis and control groups was 10.07/8.731 femtoliter (fL) (p=0.000), and 9.45/8.731 fL (p=0.000) for SIRS and control groups. In the group of sepsis patients, the MPV was found to be at cut-off 8.915, sensitivity 71%, and specificity 63.9%. In the group of patients with SIRS, MPV was found to be at cut-off 8.85, sensitivity 69.6%, and specificity 62.5%. For the MPV/PLT values, the specificity and sensitivity were found to be insignificant. Conclusion: This study shows that although there was no significant reduction in the PLT values between the sepsis and SIRS patients, the MPV and MPV/PLT ratio values were found to have significant differences. However, the specificity and sensitivity of the values were not reliable standard to be used as a test. PMID:26446329

    Outside pregnancy, both obesity and diabetes mellitus are associated with changes in inflammatory cytokines. Obesity in pregnancy may be complicated by gestational diabetes mellitus (GDM) and\\/or fetal macrosomia. The objective of this study was to determine the correlation between maternal cytokines and fetomaternal adiposity in the third trimester in women where the important confounding variable GDM had been excluded. Healthy women with a singleton pregnancy and a normal glucose tolerance test at 28 weeks gestation were enrolled at their convenience. Maternal cytokines were measured at 28 and 37 weeks gestation. Maternal adiposity was assessed indirectly by calculating the Body Mass Index (BMI), and directly by bioelectrical impedance analysis. Fetal adiposity was assessed by ultrasound measurement of fetal soft tissue markers and by birthweight at delivery. Of the 71 women studied, the mean maternal age and BMI were 29.1 years and 29.2 kg\\/m(2) respectively. Of the women studied 32 (45%) were obese. Of the cytokines, only maternal IL-6 and IL-8 correlated with maternal adiposity. Maternal TNF-α, IL-β, IL-6 and IL-8 levels did not correlate with either fetal body adiposity or birthweight. In this well characterised cohort of pregnant non-diabetic women in the third trimester of pregnancy we found that circulating maternal cytokines are associated with maternal adiposity but not with fetal adiposity.

    Full Text Available This study evaluates the contribution of peripheral biomarkers to comorbidities and clinical findings in autism. Seventeen autistic children and age-matched typically developing (AMTD, between three to nine years old were evaluated. The diagnostic followed the Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DMS-IV and the Childhood Autism Rating Scale (CARS was applied to classify the severity. Cytokine profile was evaluated in plasma using a sandwich type ELISA. Paraclinical events included electroencephalography (EEG record. Statistical analysis was done to explore significant differences in cytokine profile between autism and AMTD groups and respect clinical and paraclinical parameters. Significant differences were found to IL-1β, IL-6, IL-17, IL-12p40, and IL-12p70 cytokines in individuals with autism compared with AMTD (p < 0.05. All autistic patients showed interictalepileptiform activity at EEG, however, only 37.5% suffered epilepsy. There was not a regional focalization of the abnormalities that were detectable with EEG in autistic patients with history of epilepsy. A higher IL-6 level was observed in patients without history of epilepsy with interictalepileptiform activity in the frontal brain region, p < 0.05. In conclusion, peripheral inflammatory markers might be useful as potential biomarkers to predict comorbidities in autism as well as reinforce and aid informed decision-making related to EEG findings in children with Autism spectrum disorders (ASD.

    2016-01-01

    Background Inflammatory markers can be helpful as part of the diagnostic workup for specific diseases or for monitoring disease activity. A third use is as a screening and/or triage tool to differentiate between the presence or absence of disease. Most research into inflammatory markers looks at diagnosis of specific diseases and comes from secondary care. Qualitative studies to explore when and why clinicians use these tests in primary care are lacking. Aim To identify clinicians’ approaches to inflammatory marker testing in primary care. Design and setting Qualitative study with 26 GPs and nurse practitioners. Method Interviews were conducted using a semi-structured topic guide. Clinicians reviewed recent cases of inflammatory marker testing in their pathology inbox. Interviews were audiorecorded and transcribed. Qualitative analysis was conducted by two of the authors. Results Clinicians are uncertain about the appropriate use of inflammatory markers and differ in their approach to testing patients with undifferentiated symptoms. Normal or significantly elevated inflammatory markers are seen as helpful, but mildly raised inflammatory markers in the context of non-specific symptoms are difficult to interpret. Clinicians describe a tension between not wanting to ‘miss anything’ and, on the other hand, being wary of picking up borderline abnormalities that can lead to cascades of further tests. Diagnostic uncertainty is a common reason for inflammatory marker testing, with the aim to reassure; however, paradoxically, inconclusive results can generate a cycle of uncertainty and anxiety. Conclusion Further research is needed to define when inflammatory marker testing is useful in primary care and how to interpret results. PMID:26852797

    The underlying mechanisms for increased osteopenia and fracture rates in patients with diabetes are not well understood, but may relate to chronic systemic inflammation. We assessed the effect of treating periodontal disease (POD), a cause of chronic inflammation, on inflammatory and bone turnover markers in patients with diabetes. Using an investigator-administered questionnaire, we screened a cross-section of patients presenting for routine outpatient diabetes care. We recruited 22 subjects with POD. Inflammatory and bone turnover markers were measured at baseline and 3 months following POD treatment (scaling, root planing and subantimicrobial dose doxycycline). There were nonsignificant reductions in high-sensitivity C-reactive protein (6.34-5.52mg/L, P = 0.626) and tumor necrosis factor-alpha (10.37-10.01pg/mL, P = 0.617). There were nonsignificant increases in urinary C-terminal telopeptide (85.50-90.23pg/mL, P = 0.684) and bone-specific alkaline phosphatase (7.45-8.79pg/mL, P = 0.074). Patients with >90% adherence with doxycycline were 6.4 times more likely to experience reduction in tumor necrosis factor-alpha (P = 0.021) and 2.8 times more likely to experience reductions in high-sensitivity C-reactive protein (P = 0.133). Treatment of POD in patients with diabetes resulted in nonsignificant lowering of inflammatory markers and nonsignificant increase in bone turnover markers. However, adherence to doxycycline therapy resulted in better treatment effects. Copyright © 2016 Southern Society for Clinical Investigation. Published by Elsevier Inc. All rights reserved.

    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

    Despite known beneficial effects of social support on cardiovascular health, the pathway through which sources of support (supervisor, coworkers, family/friends) influence inflammatory markers is not completely understood. We investigated the independent and moderating associations between social support and inflammatory markers. A total of 137 male white-collar employees underwent a blood draw for measurement of high-sensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), monocyte and leukocyte counts, and completed a questionnaire on social support. Multivariable linear regression analyses controlling for covariates revealed that supervisor support was inversely associated with IL-6 (β = -0.24, p markers. Social support from the immediate supervisor may be a potential mechanism through which social support exerts beneficial effects on inflammatory markers in working men.

    The term acute coronary syndrome (ACS) encompasses a range of thrombotic coronary artery diseases, including unstable angina (UA) and both ST-segment elevation (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). Bio markers play an important role in the diagnosis of non-ST-elevation ACS (NSTE-ACS) including unstable angina and non-STEMI. Among these, cardiac troponin and creatine phosphokinase myocardial band appeared to be the most sensitive and specific markers of myocardial injury. The important role of inflammatory processes in the development and progression of atherosclerosis has been clearly established. Different circulating inflammatory bio markers indicating the instability of atherosclerotic plaque have been identified and serve as diagnostic tools for the identification of patients with unstable angina or acute myocardial infarction and to identify risk patients. The present study was carried out on twenty patients with (NSTE-ACS). The level of serum troponin I (cTnI), creatine phosphokinase-total (CPK-T), myocardial band of creatine phosphokinase (CPK-MB), pregnancy associated plasma protein-A (PAPP-A) and highly sensitive C-reactive protein (hsCRP) were determined. The results showed increase in the level of cardiac bio markers (cTnI, CPK-MB, CPK-T) and inflammatory markers (PAPP-A, hsCRP). It could be concluded that the increase in inflammatory markers correlate especially PAPP-A in NSTE-ACS with the increase of cardiac bio markers

    The practice of prolonged exercise with high intensity, as seen in triathlon training, can cause physiological imbalances that might result in muscle fatigue, muscle damage and changes in systemic inflammatory response, thus reduce the athletes physical performance, therefore, both adequate total caloric and macronutrient intake also the use of a specific ergogenic aid, as taurine supplementation would be an alternative to prevent inflammation and muscle damage. In order to verify the effects of 8 weeks of taurine and chocolate milk supplementation, markers of muscle damage, inflammation, and aerobic capacity were quantified in triathletes. A double-blind, crossover, randomized study was conducted with 9 male long distance triathletes, aged 25-35 years. Supplementation of 3 g of taurine (TAU) or placebo (PLA) associated with 400 ml low fat chocolate milk was performed during an 8-week period. In order to verify the effects of the supplementation protocol markers of muscle damage as lactate dehydrogenase (LDH) and creatine kinase (CK), and inflammatory markers tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were quantified, also triathletes performance was evaluated by exhaust test on a treadmill. It was observed a significant increase in taurine and CK plasma levels after TAU supplementation (p=0.02 and p=0.01, respectively). However, LDH concentrations did not differ significantly after the supplementations performed, and there were no changes in physical performance parameters; anaerobic threshold, perceived exertion, heart rate, and the concentrations of IL-6 and TNF-α. Taurine supplementation did not provide benefits on performance and muscle damage in triathletes.

    The immune system is essential for the control and elimination of infections, and macrophages are cells that act as important players in orchestrating the various parts of the inflammatory/immune response. Amino acids play important role in mediating functionality of the inflammatory response, especially mediating macrophages functions and cytokines production. We investigated the influence of glutamine, taurine and their association on the modulation of inflammatory pathway markers in macrophages. The RAW 264.7 macrophage cell line was cultivated in the presence of glutamine and taurine and proliferation rates, cell viability, cell cycle phases, IL-1α, IL-6, IL-10 and TNF-α as well as H 2 O 2 production and the expression of the transcription factor, NFκB, and its inhibitor, IκBα, were evaluated. Our results showed an increase in viable cells and increased proliferation rates of cells treated with glutamine concentrations over 2 mM, as well as cells treated with both glutamine and taurine. The cell cycle showed a higher percentage of cells in the phases S, G2 and M when they were treated with 2 or 10 mM glutamine, or with glutamine and taurine in cells stimulated with lipopolysaccharide. The pNFκB/NFκB showed reduced ratio expression when cells were treated with 10 mM of glutamine or with glutamine in association with taurine. These conditions also resulted in reduced TNF-α, IL-1α and H 2 O 2 production, and higher production of IL-10. These findings demonstrate that glutamine and taurine are able to modulate macrophages inflammatory pathways, and that taurine can potentiate the effects of glutamine, illustrating their immunomodulatory properties.

    During inflammatory cardiomyopathy matrix metalloproteinases are crucially involved in cardiac remodeling. The aim of the present study was to investigate whether the "extracellular matrix metalloproteinase inducer" EMMPRIN (CD147) and its ligand Cyclophilin A (CyPA) are upregulated in inflammatory cardiomyopathy and may serve as diagnostic markers. Therefore, a series of 102 human endomyocardial biopsies were analyzed for the expression of EMMPRIN and CyPA and correlated with histological and immunohistological findings. Endomyocardial biopsies were stained for EMMPRIN and CyPA in addition to standard histology (HE, Trichrom) and immunohistological stainings (MHC-II, CD68, CD3). 39 (38.2%) biopsies met the immunohistological criteria of an inflammatory cardiomyopathy. EMMPRIN, which was predominantly expressed on cardiomyocytes, was slightly (but significantly) upregulated in non inflammatory cardiomyopathies compared to normal histopathological findings and highly upregulated in inflammatory cardiomyopathy compared to both non inflammatory cardiomyopathy and normal histopathology. In contrast, CyPA reveals no enhanced expression in non inflammatory cardiomyopathies and a highly enhanced expression in inflammatory cardiomyopathy, where it is closely associated with leucocytes infiltrates. We found a strong correlation between both EMMPRIN and CyPA with the expression of MHC-II molecules (correlation coefficient 0.475 and 0.527, pEMMPRIN and CyPA with CD68 (correlation coefficient 0.393 and 0.387, pEMMPRIN is enhanced in both inflammatory and non inflammatory cardiomyopathies and can serve as a marker of myocardial remodeling. CyPA may represent a novel and specific marker for cardiac inflammation. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Dysregulation of the hypothalamic-pituitary-adrenal (HPA axis and inflammatory systems is a consistent finding in patients with Major Depressive Disorder (MDD. Cortisol is often assessed by measurement of the cortisol awakening response (CAR and/or diurnal cortisol levels. Some methods of cortisol measurement overestimate cortisol concentration due to detection of other glucocorticoids including the relatively inert cortisone, therefore this study aimed to assess the presence of both cortisol and cortisone, and the cortisol-cortisone catalyzing enzyme 11β-hydroxysteroiddehydrogenase type 1 (11β-HSD1, in depressed patients and controls. Because the HPA axis is known to regulate the body’s immune system, relationships between measures of cytokines and cortisol were also assessed. Saliva samples were collected from 57 MDD patients and 40 healthy controls at five post-wakening time points (0, +30, +60, +720 and +750 min. Glucocorticoid concentrations were measured by liquid chromatography mass spectrometry. Whole blood mRNA expression of several inflammatory markers was measured by quantitative polymerase chain reaction. This study replicated the common finding of elevated morning cortisol and reduced CAR reactivity in MDD and found no differences in cortisone or 11β-HSD1 mRNA measures. There was a negative association between interleukin 1-β (IL-1β mRNA and morning cortisol reactivity within the depressed group, indicating that dysregulation of the HPA axis and immune system may be interconnected.

    Full Text Available Differentiating sepsis from other noninfectious causes of systemic inflammation is often difficult in the elderly. The aim of this study was to evaluate the ability of C-reactive protein (CRP, Erythrocyte Sedimentation Rate (ESR, procalcitonin (PCT, and Interleukin-6 (IL-6 to identify elderly patients with sepsis. In this single center prospective observational study, we included all consecutive elderly patients admitted with suspected sepsis and systemic inflammatory response syndrome (SIRS in an emergency department. Blood samples for measuring CRP, PCT, IL-6, ESR and white blood cells (WBC count were taken at first day of admission. Sensitivity, specificity, positive and negative predictive values were calculated for each inflammatory markers being studied. A total of 150 elderly patients aged 65 and older, 50 with sepsis and 50 with SIRS, and fifty individuals in a normal health status were included. CRP exhibited the greatest sensitivity (98% and negative predictive value (98.6% and performed best in differentiating patients with sepsis from those with SIRS. In a receiver operating characteristic curve analysis, IL-6 performed best in distinguishing between SIRS and the control group (AUC 0.75, 95% CI. On the other hand, both CRP and ESR appeared to be a more accurate diagnostic parameter for differentiating sepsis from SIRS among elderly patients.

    Full Text Available Nitric oxide (NO is not only important in host defense and homeostasis but it is also regarded as harmful and has been implicated in the pathogenesis of a wide variety of inflammatory and autoimmune diseases. The presence of NO in periodontal disease may reflect the participation of an additional mediator of bone resorption responsible for disease progression. The aim of this study was to assess the level of NO in serum in chronic periodontitis, and correlate these levels with the severity of periodontal disease. Sixty subjects participated in the study and were divided into two groups. NO levels were assayed by measuring the accumulation of stable oxidative metabolite, nitrite with Griess reaction. Results showed subjects with periodontitis had significantly high nitrite in serum than healthy subjects. NO production is increased in periodontal disease, this will enable us to understand its role in disease progression and selective inhibition of NO may be of therapeutic utility in limiting the progression of periodontitis.

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

    Lauren Winter

    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.

    Full Text Available Systemic inflammation is important in obstructive sleep apnea (OSA pathophysiology and its comorbidity. We aimed to assess the levels of inflammatory biomarkers in a large sample of OSA patients and to investigate any correlation between these biomarkers with clinical and polysomnographic (PSG parameters. This was a cross-sectional study in which 2983 patients who had undergone a polysomnography for OSA diagnosis were recruited. Patients with known comorbidities were excluded. Included patients (n=1053 were grouped according to apnea-hypopnea index (AHI as mild, moderate, and severe. Patients with AHI < 5 served as controls. Demographics, PSG data, and levels of high-sensitivity C-reactive protein (hs-CRP, fibrinogen, erythrocyte sedimentation rate (ESR, and uric acid (UA were measured and compared between groups. A significant difference was found between groups in hs-CRP, fibrinogen, and UA. All biomarkers were independently associated with OSA severity and gender (p<0.05. Females had increased levels of hs-CRP, fibrinogen, and ESR (p<0.001 compared to men. In contrast, UA levels were higher in men (p<0.001. Our results suggest that inflammatory markers significantly increase in patients with OSA without known comorbidities and correlate with OSA severity. These findings may have important implications regarding OSA diagnosis, monitoring, treatment, and prognosis. This trial is registered with ClinicalTrials.gov number NCT03070769.

The level of white blood cell (WBC), neutrophil, lymphocyte, monocyte, platelet, albumin, neutrophil lymphocyte ratio (NLR), derived NLR (dNLR), platelet lymphocyte ratio (PLR), monocyte lymphocyte ratio (MLR) and prognostic nutritional index (PNI) were compared between the CP and other sellar region tumors. A receiver operating characteristics (ROC) curve analysis was performed to evaluate the diagnostic significance of the peripheral blood inflammatory markers and their paired combinations for CP including its pathological types. Patients with CP had higher levels of pre-operative WBC, lymphocyte and PNI. The papillary craniopharyngioma (PCP) group had higher neutrophil count and NLR than the adamantinomatous craniopharyngioma (ACP) and healthy control groups whereas the ACP group had higher platelet count and PNI than the PCP and healthy control groups. There were not any significant differences in preoperative inflammatory markers between the primary and recurrent CP groups. The AUC values of WBC, neutrophil, NLR + PLR and dNLR + PLR in PCP were all higher than 0.7. Inflammation seems to be closely correlated with CP's development. The preoperative inflammatory markers including WBC, neutrophil, NLR + PLR and dNLR + PLR may differentially diagnose PCP, pituitary tumor (PT) and Rathke cleft cyst (RCC). In addition, some statistical results in this study indirectly proved previous experimental conclusions and strictly matched CP's biological features.

    Full Text Available Abstract Background Inflammation is implicated in causing diabetes. We tested whether transcription factor 7 like-2 (TCF7L2 gene polymorphisms (rs12255372 and rs7903146, consistently associated with type 2 diabetes, are associated with plasma concentrations of inflammatory markers before and after three weeks of daily treatment with fenofibrate. Methods Men and women in the Genetics of Lipid-Lowering Drugs and Diet Network study (n = 1025, age 49 ± 16 y were included. All participants suspended use of lipid-lowering drugs for three weeks and were then given 160 mg/day of fenofibrate for three weeks. Inflammatory markers and lipids were measured before and after fenofibrate. ANOVA was used to test for differences across TCF7L2 genotypes. Results Under the additive or dominant model, there were no significant differences (P > 0.05 in the concentrations of inflammatory markers (hsCRP, IL-2, IL-6, TNF-α and MCP-1 across TCF7L2 genotypes in the period before or after treatment. For both rs12255372 and rs7903146, homozygote T-allele carriers had significantly higher (P Conclusion Overall these data show no association between TCF7L2 polymorphisms and the inflammatory markers suggesting that the effects of TCF7L2 on diabetes may not be via inflammation.

    Fibromyalgia syndrome (FMS) is characterized by chronic widespread pain and systemic symptoms. The aetiology and pathogenesis of fibromyalgia are not yet fully understood. Blood neutrophil/lymphocyte ratio (NLR) is a marker of systemic inflammatory response. Platelet distribution width (PDW) and mean platelet volume (MPV) are the determinants of platelet activation and studied as markers in inflammatory diseases. The aim of the present study was to evaluate levels of NLR,PDW and MPV in patients with fibromyalgia. A total of 197 FMS patients and 53 healthy controls are included in the study. Demographic characteristics, erythrocyte sedimentation rate, C-reactive protein, neutrophil, lymphocyte and platelet counts, platelet distribution width and mean platelet volume levels were recorded. In the patient group, the blood NLR and MPV were significantly higher and the PDW was significantly lower compared to the control group. In the roc curve analysis, blood PDW ≥had 90.4% sensitivity and 90% specificity in predicting fibromyalgia. The results of this study suggest NLR and PDW as promising inflammatory markers indicating fibromyalgia and may be beneficial in facilitating the diagnosis of FMS patients.

    Previous studies suggest that inflammatory molecules play an important role in the pathophysiology of Bipolar Disorder (BD). The evidence suggests that BD may present a progressive course. Therefore there are theories that postulate the relationship between progression and stages of the disease with distinct peripheral biomarkers. The aim of this study was to carry out a systematic review of the literature of studies about the association between peripheral inflammatory markers and clinical variables related with staging in BD patients. We conducted a systematic review using electronic databases: PubMed, SciELO, LiLACS and PsycINFO. Keywords were divided into inflammatory markers and, BD and staging. Studies involving euthymic BD patients, studies evaluating peripheral biomarkers and studies correlating these with clinical variables related to neuroprogression or stage of BD were included. We present and discuss the methods and findings of ten articles. The inflammatory markers were measured with different techniques and show some contradictories results. The TNF superfamily and inflammatory cytokines may have a relationship with the neuroprogression of the disease. This study suggests that TNF and ILs could play a role in neuroprogression. However, longitudinal studies are needed to clarify the relationship between factors associated with neuroprogression. Copyright © 2017 Asociación Colombiana de Psiquiatría.

    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.

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.

    Full Text Available BACKGROUND: Cellular and animal studies implicate multiple roles of amylin in regulating insulin action, glucose and lipid metabolisms. However, the role of amylin in obesity related metabolic disorders has not been thoroughly investigated in humans. Therefore, we aimed to evaluate the distribution of circulating amylin and its association with metabolic syndrome (MetS and explore if this association is influenced by obesity, inflammatory markers or insulin resistance in apparently healthy Chinese. METHODS: A population-based sample of 1,011 Chinese men and women aged 35-54 years was employed to measure plasma amylin, inflammatory markers (C-reactive protein [CRP] and interleukin-6 [IL-6], insulin, glucose and lipid profiles. MetS was defined according to the updated National Cholesterol Education Program Adult Treatment Panel III criteria for Asian-Americans. RESULTS: Plasma amylin concentrations were higher in overweight/obese participants than normal-weight counterparts (P<0.001 without sex difference. Circulating amylin was positively associated with CRP, IL-6, BMI, waist circumference, blood pressure, fasting glucose, insulin, amylin/insulin ratio, HOMA-IR, LDL cholesterol and triglycerides, while negatively associated with HDL cholesterol (all P<0.001. After multiple adjustments, the risk of MetS was significantly higher (odds ratio 3.71; 95% confidence interval: 2.53 to 5.46 comparing the highest with the lowest amylin quartile. The association remained significant even further controlling for BMI, inflammatory markers, insulin or HOMA-IR. CONCLUSIONS: Our study suggests that amylin is strongly associated with inflammatory markers and MetS. The amylin-MetS association is independent of established risk factors of MetS, including obesity, inflammatory markers and insulin resistance. The causal role of hyperamylinemia in the development of MetS needs to be confirmed prospectively.

    Full Text Available BACKGROUND: Postoperative cognitive dysfunction (POCD is common following cardiac and non-cardiac surgery, but the pathogenic mechanisms remain unknown. Many studies suggest that an inflammatory response is a key contributor to POCD. The current meta-analysis shows that the levels of peripheral inflammatory markers are associated with POCD. METHODS: An online search was performed to identify peer-reviewed studies without language restriction that measured peripheral inflammatory markers of patients with and without POCD, using PubMed, ScienceDirect, SinoMed and the National Knowledge Infrastructure database. Extracted data were analyzed with STATA (version 12.The standardized mean difference (SMD and the 95% confidence interval (95%CI were calculated for each outcome using a random effect model. Tests of heterogeneity assessment of bias, and meta-regression were performed in the meta-analysis. RESULTS: A total of 13 studies that measured the concentrations of peripheral inflammatory markers were included. The current meta-analysis found significantly higher concentrations of S-100β(SMD[95%CI] (1.377 [0.423, 2.331], p-value < 0.001, N [POCD/non-POCD] =178/391, 7 studies, and interleukin(IL-6 (SMD[95%CI] (1.614 [0.603,2.624], p-value < 0.001, N[POCD/non-POCD] = 91/99, 5 studies, but not of neuron specific enolase, interleukin-1β, or tumor necrosis factor-α , in POCD compared with patients without POCD. In meta-regression analyses, a significant positive association was found between the SMD and the preoperative interleukin-6 peripheral blood concentration in patients with POCD (Coef.= 0.0587, p-value=0.038, 5 studies. CONCLUSIONS: This study shows that POCD is indeed correlated with the concentrations of peripheral inflammatory markers, particularly interleukin-6 and S-100β.

    We evaluated the association between two aspects of social relationships and six inflammatory markers in Taiwan and the U.S. These two countries share similar levels of current life expectancy, but exhibit important differences in social structure. The data comprised population based samples from Taiwan (aged 53+; n=962) and the U.S. (aged 35-86; n=990) collected between 2003 and 2009. Circulating levels of interleukin-6 (IL-6), C-reactive protein (CRP), fibrinogen, and soluble forms of intercellular adhesion molecule 1, E-selectin, and IL-6 receptor (sIL-6R) were measured in fasting blood samples. A social integration score was based on marital status, contact with family and friends, church attendance, and other social participation. A perceived social support index was based on questions regarding the availability of care and support from family and friends. Linear regression models tested the association between these two measures and each inflammatory marker controlling for sociodemographic characteristics, obesity, medication use, and baseline health status. After adjusting for potential confounders, social integration had a significant but weak inverse association with CRP in Taiwan. Perceived social support was significant in two of 12 models, and the coefficient was positive (i.e., higher support was associated with higher CRP and sIL-6R in the U.S.). We found no evidence that the coefficients for social relationship measures varied by sex or age. Our results yielded limited evidence of a weak association between two dimensions of social relationships and six inflammatory markers in Taiwan and the U.S. Given that the literature suggests a strong link between social relationships and mortality, and that inflammation plays an important role in the leading causes of death, we had expected to find consistent and moderately strong associations between social relationships and inflammatory markers.

    We report ~17.6M genetic variants from whole-genome sequencing of 2,120 Sardinians; 22% are absent from prior sequencing-based compilations and enriched for predicted functional consequence. Furthermore, ~76K variants common in our sample (frequency >5%) are rare elsewhere (Genomes Project). We assessed the impact of these variants on circulating lipid levels and five inflammatory biomarkers. Fourteen signals, including two major new loci, were observed for lipid levels, and 19, including two novel loci, for inflammatory markers. New associations would be missed in analyses based on 1000 Genomes data, underlining the advantages of large-scale sequencing in this founder population. PMID:26366554

    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

    Polycystic ovary syndrome (PCOS) is associated with increased cardiovascular disease risk. The effect of weight loss on the vascular inflammatory markers plasminogen activator inhibitor-1 (PAI-1), asymmetric dimethylarginine (ADMA), soluble vascular cell adhesion molecule-1 (sVCAM-1) and intracellular adhesion molecule-1 (sICAM-1) is unknown. Overweight women with (n=14) and without (n=13) PCOS of comparable age and body mass index undertook an 8-week weight-loss programme. Women with PCOS had elevated PAI-1, sVCAM-1 and sICAM-1 before and after weight loss compared with the controls. For all women, sVCAM-1 (P=0.026) and sICAM-1 (P=0.04) decreased with weight loss. Women with PCOS have elevated inflammatory markers, which are partially reduced by weight loss. Copyright © 2012 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Obstructive Sleep Apnea (OSA is a sleep-related breathing disorder associated with the development of cardiovascular diseases and atherosclerosis. Systemic inflammation plays an important role in the development of cardiovascular complications in OSA patients. The aim of the study was to evaluate the relationship between carotid intima-media thickness (cIMT and inflammatory markers plasma levels in OSA patients. We enrolled 80 OSA patients and 40 controls matched for age and body mass index (BMI. The presence and severity of sleep apnea was determined by in-laboratory portable monitoring (PM. Demographic data, blood pressure, heart rate, and cIMT were measured. High-sensitive C-Reactive Protein (hsCRP, interleukin (IL-6, tumor necrosis factor (TNF-α and pentraxin (PTX-3 serum concentrations were detected. cIMT was higher in OSA patients than controls (0.89 ± 0.13 mm vs. 0.65 ± 0.1 mm, p < 0.01. Moderate-severe OSA patients (0.95 ± 0.09 mm had significantly increased cIMT than mild OSA (0.76 ± 0.1 mm; p < 0.01 and control (0.65 ± 0.1 mm; p < 0.01. hsCRP, IL-6, TNF-α, and PTX-3 in patients with OSA (1.67 ± 0.66 mg/L, 2.86 ± 1.39 pg/mL, 20.09 ± 5.39 pg/mL, 2.1 ± 0.59 ng/mL, respectively were significantly higher than in controls (1.08 ± 0.53 mg/L, p < 0.01; 1.5 ± 0.67 pg/mL, p < 0.01; 12.53 ± 3.48 pg/mL, p < 0.01; 1.45 ± 0.41 ng/mL, p < 0.01, respectively. Carotid IMT was significantly correlated to CRP (r = 0.44; p < 0.01, IL-6 (r = 0.42; p < 0.01, TNF-α (r = 0.53; p < 0.01, and PTX-3 (r = 0.49; p < 0.01. OSA patients showed increased cIMT, CRP, IL-6, TNF-α, and PTX-3 levels. Inflammatory markers levels are correlated to cIMT in OSA patients.

    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.

    Declines in ovarian function in postmenopausal women may contribute to increase inflammatory cytokines, which can lead to chronic diseases. However, studies have shown that exercise interventions are important to manage inflammatory conditions. Thus, the objective of this study was to analyze the effect of exercise intervention on inflammatory markers among obese and postmenopausal women. 70 women composed the sample (Exercise group [EG; n = 35] and nonexercise group [nEG; n = 35]). IL-6, TNF-α, and IL-10 were the inflammatory markers analyzed. Exercise program was 20 weeks long and consisted of aerobic and neuromuscular training. Data about chronic diseases, medication use, dietary intake, body composition and biochemical variables were collected. EG showed significant reductions in body mass index, waist circumference and body fat percentage, as well as increased lean body mass. EG showed significant reductions in TNF-α and significant interaction between group and intervention time. Reductions in IL-10 were identified only in nEG. Substantial effect of exercise intervention was observed with increased ratio of IL-10/IL-6 and IL-10/TNF-α. Combination of aerobic exercise and resistance training was effective in reducing inflammation. Thus, implementation and maintenance of similar exercise programs can contribute to reduce chronic inflammation among obese postmenopausal women.

    Full Text Available Objective: Total knee arthroplasty (TKA is a major risk factor for thrombosis in patients over 40 years of age and this risk persists for several weeks after the surgery. Since inflammatory mechanisms affect coagulation and the natural anticoagulant system, we aimed to investigate protein C activities and inflammatory markers in patients undergoing TKA surgery.Material and Methods: We included 20 osteoarthritis patients and 20 healthy controls. Protein C activity and tumor necrosis factor-α (TNF-α levels in plasma and synovia were evaluated by ELISA technique. Results: In the patient group, protein C activities decreased and TNF-α levels increased significantly both in synovia and plasma when compared with the controls. Erythrocyte sedimentation rate of the patient group was found to be significantly elevated in comparison to the controls. On the other hand, serum C reactive protein values increased insignificantly when compared to controls.Conclusion: The decreased activity of protein C and increased levels of inflammatory markers in preoperative plasma and synovia of the patient group may enhance the risk for developing thrombosis.

    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.

    Recent research has focused on the use of inflammatory biomarkers in the prediction of cardiovascular risk. However, information is scant regarding the association between these inflammatory markers with other cardiovascular risk factors in Asian Indians, particularly in women. To explore the association between inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP) and white blood cell (WBC) count and cardiovascular risk factors such as overall and central adiposity, blood pressure, lipid and lipoprotein variables and fasting glucose. We conducted a cross-sectional analysis on 100 women aged 35-80 years. Participants were selected following cluster sampling methodology from 12 different randomly selected urban wards of Kolkata Municipal Corporation. Hs-CRP has a significant association with body mass index (BMI) ( p HDL-C) and both inflammatory markers, hs-CRP (p = 0.031) and WBC count, (p = 0.014). Apolipoprotein A1 (Apo A1) was also negatively associated with hs-CRP. WBC count has significant correlation with fasting glucose and total cholesterol (TC) /HDL-C ratio. Using logistic regression, adjusting for age, BMI (odds ratio/OR, 1.186; confidence interval/CI, 1.046-1.345; p = 0.008) and WC (OR, 1.045; CI, 1.005-1.087; p = 0.027) were the covariates significantly associated with hs-CRP. In the present study, risk factors like BMI, WC, and HDL-C and apo A1 show significant association with hs-CRP. WBC count was significantly correlated with HDL-C, fasting glucose, TC/HDL-C ratio in women.

    The relationship between multiple lifestyle components analyzed in combination and inflammation remains understudied. We aimed to assess the association between a Healthy Lifestyle Score (HLS) that includes adherence to five behavioral components (diet, physical activity and sedentary behaviors, smoking, social support and network, and sleep) and inflammatory markers, as well as the role of the HLS in inflammation among individuals with cardiometabolic conditions, in Puerto Rican adults. In a cross-sectional study of 842 Puerto Ricans adults (aged 45-75 y) living in Boston, MA, the HLS (range = 0-190; maximum indicative of healthiest adherence) was analyzed for association with three inflammatory markers: interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP). In multivariable-adjusted models, the HLS was inversely associated with IL-6 (β ± SE = -0.55 ± 0.13; P markers independently of the other HLS components. Significant inverse associations were observed for each 20-unit increase in HLS and IL-6 and TNF-α for participants with hypertension (n = 600; β ± SE = -0.58 ± 0.16; -0.46 ± 0.16, respectively) and with overweight/obesity (n = 743; β ± SE = -0.59 ± 0.13; -0.50 ± 0.14, respectively), but not for those with diabetes (n = 187) or heart disease (n = 192). The HLS was not associated with CRP, after adjustment for potential confounders. Higher adherence to multiple lifestyle behaviors was associated with lower concentrations of inflammatory markers. Because low-grade inflammation may precede chronic diseases, following an overall healthy lifestyle may help lower risk of these diseases.

    Magnesium has been reported to improve glucose utilization in diabetes mellitus. However, information on its effects on anemic and inflammatory markers in diabetes mellitus is limited. This study investigated the effect of oral magnesium (Mg) treatment on some markers of anemia and inflammation in 25 male Wistar rats. Rats (200 ± 15 g) were randomly divided into five groups (n = 5). Group 1 was control (received orally 0.2 mL distilled water daily), group 2 (Diabetic Untreated), group 3 (Diabetic Mg treated-100 mg/kg bw), group 4 (Diabetic Mg treated-250 mg/kg bw), group 5 (Diabetic Insulin treated-1 IU/kg bw). Diabetes was induced with a single dose of alloxan (100 mg/kg intraperitoneal (i.p.)). All treatments were done for 14 days. Anemic and inflammatory markers were investigated on blood samples obtained from each animal using standard laboratory methods. Significant increase (p DMg 100 (5.86 ± 0.74 × 10 9 /L) and DMg 250 (5.06 ± 0.78 × 10 9 /L). Hemoglobin concentration, packed cell volume (PCV) and red blood cell (RBC) count was decreased (p DMg 100, and DI rats. Erythrocyte sedimentation rate (ESR) was significantly increased (p DMg 100, DMg 250, and DI groups. Fibrinogen level was increased (p DMg 100 (0.30 ± 0.03 g/dL), DMg 250 (0.22 ± 0.04 g/dL), and DI (0.36 ± 0.02 g/dL) rats were comparable to control (0.26 ± 0.02 g/dL). Total protein, albumin, and globulin levels were decreased in DU rats compared to normal control, DMg 100, DMg 250, and DI rats. In conclusion, anemia and increased hematologic and metabolic inflammatory markers may be associated with untreated diabetes mellitus. Treatment of alloxan-induced diabetic rats with magnesium improved the anemic state and reduced hematologic and metabolic inflammatory markers.

To examine the levels of inflammatory markers in obese community-dwelling children with OSA, as compared to no-OSA, and their association with clinical and polysomnographic (PSG) variables. Methods. In this cross-sectional, prospective multicenter study, healthy obese Spanish children (ages 4-15 years) were randomly selected and underwent nocturnal PSG followed by a morning fasting blood draw. Plasma samples were assayed for multiple inflammatory markers. 204 children were enrolled in the study; 75 had OSA, defined by an obstructive respiratory disturbance index (RDI) of 3 events/hour total sleep time (TST). BMI, gender, and age were similar in OSA and no-OSA children. Monocyte chemoattractant protein-1 (MCP-1) and plasminogen activator inhibitor-1 (PAI-1) levels were significantly higher in OSA children, with interleukin-6 concentrations being higher in moderate-severe OSA (i.e., AHI > 5/hrTST; P < 0.01), while MCP-1 levels were associated with more prolonged nocturnal hypercapnia (P < 0.001). IL-6, MCP-1, and PAI-1 are altered in the context of OSA among community-based obese children further reinforcing the proinflammatory effects of sleep disorders such as OSA. This trial is registered with ClinicalTrials.gov NCT01322763.

    Using the regression model building the relationships between the concentration of 37 fatty acids of blood plasma phospholipids of 41 patients with coronary artery disease after coronary stent implantation, the inflammatory response and oxidative stress markers were estimated. The dynamics of the inflammatory response and the oxidative stress was indicated by measuring plasma concentrations of highly sensitive C-reactive protein, interleukin-6, serum amyloid A and malondialdehyde before, 24h after stent implantation. The multiple linear regression analysis was preceded by an exploratory data analysis, principal component analysis, factor analysis and cluster analysis, which proved a hidden internal relation of 37 fatty acids. The concentration of cerotic acid (C26:0) has been positively associated with an increase of malondialdehyde concentration after stent implantation, while the concentrations of tetracosatetraenoic (C24:4 N6) and nonadecanoic (C19:0) acids were associated with decrease of lipoperoxidation. The increase of interleukin-6 during the 24h after implantation was associated with higher levels of pentadecanoic acid (C15:0) and lower levels of α-linolenic acid (C18:3 N3). Regression models found several significant fatty acids at which the strength of the parameter β for each fatty acid on selected markers of C-reactive protein, malondialdehyde, interleukin-6 and serum amyloid A was estimated. Parameter β testifies to the power of the positive or negative relationship of the fatty acid concentration on the concentration of selected markers. The influencing effect of the cerotic acid (C26:0) concentration in plasma phospholipids exhibiting parameter β=140.4 is, for example, 3.5 times higher than this effect of n-3 tetracosapentaenoic acid (C24:5 N3) with β=40.0. Composition of fatty acids in plasma phospholipids shows spectrum of fatty acids available for intercellular communication in systemic inflammatory response of organism and should affect

    Full Text Available Metabolic syndrome (MetS is a primary risk factor for cardiovascular disease and is associated with a proinflammatory state. Here, we assessed the contribution of inflammatory and oxidative stress markers towards prediction of MetS. A total of 2316 individuals were recruited in Phase I of the Indian Atherosclerosis Research Study (IARS. Modified ATPIII guidelines were used for classification of subjects with MetS. Among the inflammatory and oxidative stress markers studied, levels of hsCRP (P<.0001, Neopterin (P=.036, and oxLDL (P<.0001 were significantly higher among subjects with MetS. Among the markers we tested, oxLDL stood out as a robust predictor of MetS in the IARS population (OR 4.956 95% CI 2.504–9.810; P<.0001 followed by hsCRP (OR 1.324 95% CI 1.070–1.638; P=.010. In conclusion, oxLDL is a candidate predictor for MetS in the Asian Indian population.

    The study examines the role inflammatory and tumor markers as biomarkers to preoperatively predict outcome in patients with epithelial appendiceal neoplasm undergoing cytoreduction and intraperitoneal chemotherapy. Associations between baseline variables, tumor markers [CEA (carcinoembyronic antigen], CA125, CA199), inflammatory markers including neutrophils-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and C-reactive protein (CRP) with progression-free survival (PFS) and overall survival (OS) were examined in patients undergoing surgical cytoreduction and intraperitoneal chemotherapy for epithelial appendiceal neoplasm. A total of 174 patients with epithelial appendiceal neoplasm (low-grade pseudomyxoma, n = 117; appendiceal cancer, n = 57) underwent cytoreduction. On univariate analysis, all 3 inflammatory and tumor markers predicted for both PFS and OS, respectively; NLR ≤ 2.6 (P = 0.01, P = 0.002), PLR ≤ 166 (P = 0.006, P = 0.016), CRP ≤ 12.5 (P = 0.001, P = 0.008), CEA (P 37 (P = 0.003), and a CRP > 12.5 (P = 0.013). A higher peritoneal cancer index (PCI > 24) was associated with elevation in CEA > 12, CA125 > 39, CA199 > 37, PLR > 166 and CRP > 12. The tumor histologic subtype was associated with CA 199 levels. The results from this investigation suggest that preoperative inflammatory markers in blood and serologic tumor markers may predict outcomes and are associated with tumor biology in patients with epithelial appendiceal neoplasm undergoing cytoreduction and intraperitoneal chemotherapy treatment.

    Full Text Available Cytokines and chemokines in the tumor microenvironment drive metastatic development and their serum levels might mirror the ongoing inflammatory reaction at the tumor site. Novel highly sensitive tools are needed to identify colorectal cancer patients at high risk of recurrence that should be more closely monitored during post-surgical follow up. Here we study whether circulating inflammatory markers might be used to predict recurrence in CRC patients.Circulating levels of the inflammatory cytokines IL-1, IL-6, IL-10, TNFalpha, CCL2, CXCL8, VEGF and the acute phase protein Pentraxin-3 were measured by ELISA in preoperative serum samples prospectively collected from a cohort of sixty-nine patients undergoing surgical resection for stage 0-IV CRC and associated with post-operative disease recurrence.Cox multivariate analysis showed that combined high levels (≥ROC cut off-value of CXCL8, VEGF and Pentraxin3 were associated with increased risk of disease recurrence [HR: 14.28; 95%CI: (3.13-65.1] independently of TNM staging. Kaplan-Meier analysis showed that CXCL8, VEGF and Pentraxin3 levels were significantly associated with worse survival (P<0.001.Circulating inflammatory mediators efficiently predicted postoperative recurrence after CRC surgery. Therefore, this study suggest that their validation in large-scale clinical trials may help in tailoring CRC post-surgical management.

    Growth differentiation factor-15 (GDF-15) is an inflammatory molecule that reacts to cell stress. Since major depression is associated with inflammation, we examined whether GDF-15 levels are elevated in patients with late-life depression. Plasma GDF-15 levels were analyzed in 350 patients diagnosed with major depressive disorder in the last six months and 128 non-depressed controls from the Netherlands Study of Depression in Older persons (age ≥ 60 years). Major depressive disorder and age of onset were assessed with the Composite International Diagnostic Interview. Severity of depressive symptoms was measured with the Inventory of Depressive Symptoms (IDS-30). Multiple linear regression models were applied to study depression (diagnosis, onset age, severity, antidepressant drug use) as determinant of GDF-15 level, adjusted for demographic and clinical variables. Plasma GDF-15 levels were 22% higher in patients with major depression compared to controls. Within the depressed group, levels were higher in patients with older age of onset. GDF-15 levels showed a small, positive correlation to the levels of the inflammatory mediators IL-6 and C-reactive protein (r=0.23, and 0.24, pdepressed subgroup, neither depression severity or antidepressant drug use was associated with GDF-15 levels in the fully adjusted models. The inflammatory factor GDF-15 does not seem to be an independent inflammatory marker for late-life major depressive disorder. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The lecture presents the materials of foreign studies on the mechanisms responsible for the formation of a systemic inflammatory response syndrome (SIRS. The hypotheses accounting for the occurrence of SIRS in emergencies are described. Adhesion molecules (AM and endothelial dysfunction are apparent to be involved in the inflammatory process, no matter what the causes of SIRS are. The current classification of AM and adhesion cascades with altered blood flow is presented. There are two lines in the studies of AM. One line is to measure the concentration of AM in the plasma of patients with emergencies of various etiology. The other is to study the impact of antiadhesion therapy on the alleviation of the severity of terminal state and its outcome. The studies provide evidence for that an adhesive process is a peculiar prelude to a systemic inflammatory response.

    Since our knowledge of the associations between socioeconomic position (SEP) over the life course and inflammatory and metabolic markers, which are excellent predictors of cardiovascular disease, remains limited, we examined the association between social mobility over the life course and these markers at older ages. Our study used cross-sectionally collected data from 6142 participants aged 50 years and older from the English Longitudinal Study of Ageing. We estimated linear and logistic models of the associations between social mobility, using information on childhood and adult SEP, C reactive protein (CRP), fibrinogen, glycated haemoglobin (HbA1c) and high-density lipoprotein (HDL) cholesterol. Our models were gradually adjusted for age, sex, chronic diseases, obesity, physical activity, alcohol consumption, smoking status and depressive symptoms. Participants who experienced upward social mobility had higher CRP, fibrinogen and HbA1c levels compared with those who had stable high SEP over the life course, but lower compared with those who experienced downward social mobility or had stable low SEP. They also had lower HDL levels compared with those who had stable high SEP or downwardly mobile. Adjustment for covariates partially explained the associations between social mobility and CRP and HDL, and fully explained those between social mobility and fibrinogen and HbA1c. Social mobility is associated with inflammatory and metabolic markers at older ages with some of the observed associations persisting after accounting for covariates. Upward social mobility appears to partially reverse the damaging effect of childhood social disadvantage on inflammatory profiles in older ages. Published by the BMJ Publishing Group Limited.

    Liang Sun

    Full Text Available OBJECTIVE: Chronic low-grade inflammation and adipokines dysregulation are linked to mechanisms underscoring the pathogenesis of obesity-related metabolic disorders. Little is known about roles of these cytokines on the association between snoring and metabolic syndrome (MetS. We aimed to investigate whether a cluster of cytokines are related to snoring frequency and its association with MetS in apparently healthy Chinese. METHODS: Current analyses used a population-based sample including 1059 Shanghai residents aged 35-54 years. Self-reported snoring frequency was classified as never, occasionally and regularly. Fasting plasma glucose, lipid profile, insulin, C-reactive protein, interleukin-6, interleukin-18, lipopolysaccharide binding protein, high-molecular-weight adiponectin and leptin were measured. MetS was defined by the updated National Cholesterol Education Program Adult Treatment Panel III criteria for Asian-Americans. RESULTS: Overweight/obese subjects had significantly higher prevalence of regular snorers than their normal-weight counterparts (34.8% vs. 11.5%, P<0.001. Regular snoring was associated with unfavorable profile of inflammatory markers and adipokines. However, those associations were abolished after adjustment for body mass index (BMI or waist circumference. The MetS risk (multivariate-adjusted odds ratio 5.41, 95% confidence interval 3.72-7.88 was substantially higher in regular snorers compared with non-snorers. Controlling for BMI remarkably attenuated the association (2.03, 1.26-3.26, while adjusting for inflammatory markers and adipokines showed little effects. CONCLUSION: Frequent snoring was associated with an elevated MetS risk independent of lifestyle factors, adiposity, inflammatory markers and adipokines in apparently healthy Chinese. Whether snoring pattern is an economic and no-invasive indicator for screening high-risk persons needs to be addressed prospectively.

  12. Fractional flow reserve is not associated with inflammatory markers in patients with stable coronary artery disease.

    Directory of Open Access Journals (Sweden)

    Jan-Willem E M Sels

    Full Text Available BACKGROUND: Atherosclerosis is an inflammatory condition and increased blood levels of inflammatory biomarkers have been observed in acute coronary syndromes. In addition, high expression of inflammatory markers is associated with worse prognosis of coronary artery disease. The presence and extent of inducible ischemia in patients with stable angina has previously been shown to have strong prognostic value. We hypothesized that evidence of inducible myocardial ischemia by local lesions, as measured by fractional flow reserve (FFR, is associated with increased levels of blood based inflammatory biomarkers. METHODS: Whole blood samples of 89 patients with stable angina pectoris and 16 healthy controls were analyzed. The patients with stable angina pectoris underwent coronary angiography and FFR of all coronary lesions. We analyzed plasma levels of cytokines IL-6, IL-8 and TNF-α and membrane expression of Toll-like receptor 2 and 4, CD11b, CD62L and CD14 on monocytes and granulocytes as markers of inflammation. Furthermore, we quantified the severity of hemodynamically significant coronary artery disease by calculating Functional Syntax Score (FSS, an extension of the Syntax Score. RESULTS: For the majority of biomarkers, we observed lower levels in the healthy control group compared with patients with stable angina who underwent coronary catheterization. We found no difference for any of the selected biomarkers between patients with a positive FFR (≤ 0.75 and negative FFR (>0.80. We observed no relationship between the investigated biomarkers and FSS. CONCLUSION: The presence of local atherosclerotic lesions that result in inducible myocardial ischemia as measured by FFR in patients with stable coronary artery disease is not associated with increased plasma levels of IL-6, IL-8 and TNF-α or increased expression of TLR2 and TLR4, CD11b, CD62L and CD14 on circulating leukocytes.

  14. Zingerone suppresses liver inflammation induced by antibiotic mediated endotoxemia through down regulating hepatic mRNA expression of inflammatory markers in Pseudomonas aeruginosa peritonitis mouse model.

    Directory of Open Access Journals (Sweden)

    Lokender Kumar

    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-inflammatory

    Full Text Available Background: Pericardial disorders are a common cause of heart disease, and the most common cause of pericarditis in developing countries is tuberculous (TB pericarditis. It has been shown that prednisolone added to standard anti-TB therapy leads to a lower rate of constrictive pericarditis. We conducted a pilot study to evaluate the effect of adjunctive prednisolone treatment on the concentration of inflammatory markers in pericardial tuberculosis, in order to inform immunological mechanisms at the disease site. Methods: Pericardial fluid, plasma and saliva samples were collected from fourteen patients with pericardial tuberculosis, at multiple time points. Inflammatory markers were measured using multiplex luminex analysis and ELISA. Results: In samples from 14 patients we confirmed a strongly compartmentalized immune response at the disease site and found that prednisolone significantly reduced IL-6 concentrations in plasma by 8 hours of treatment, IL-1beta concentrations in saliva, as well as IL-8 concentrations in both pericardial fluid and saliva by 24 hours. Conclusion: Monitoring the early effect of adjunctive immunotherapy in plasma or saliva is a possibility in pericarditis. Keywords: Tuberculosis, HIV, Pericarditis, Steroids, Treatment monitoring

    Periodontal tissue changes exerted by external forces in orthodontic treatment allow tooth movement. The changes in periodontal tissues i.e. inflammation can be monitored using gingival crevicular fluid (GCF). GCF is a component of saliva. Saliva could be used to monitor periodontal disease progression. The use of saliva to monitor periodontal tissues changes during orthodontic treatment is still unknown. Therefore, we observed the profiles of inflammatory markers namely creatine kinase ('CK), nitric oxide (NO), lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) in saliva of orthodontic patients to evaluate their importance in orthodontic treatment. A total of 21 subjects (13 female and 8 male) participated in this study. Samples were collected from gingival crevicular fluid at three period of archwire changes: baseline (M0), 2 weeks after 0.014" NiTi archwire (M1), and 2 weeks after 0.018" NiTi archwire (M2). All enzyme activities i.e. CK, LDH and AST were measured spectrophotometrically at 340 nm. Griess assay was used to measure nitric oxide level. CK activity, NO level, LDH activity and AST activity in saliva samples did not show significant differences among period of archwire changes. The use of inflammatory marker profiles in saliva may not represent the changes in periodontal tissues during orthodontic treatment.

    Full Text Available Objective: to evaluate the impact of various methods of anesthesia and treatment on the development of a systemic inflammatory reaction (SIR in gynecological patients. Subjects and methods. The manifestations of SIR were studied in 426 patients who had undergone standard operations on the uterine appendages via traditional laparoscopic access. Ninety-seven women had unoptimized anesthetic maintenance and postoperative preventive antibacterial therapy (Group 1; 95 women had unop-timized anesthetic maintenance and pre- and postoperative massive antibacterial therapy (Group 2; 103 women had optimized anesthetic maintenance and preventive antibacterial therapy (Group 3; 131 women had optimized anesthetic maintenance and massive antibacterial therapy (Group 4. Results. Antibacterial therapy was not found to affect the manifestations of SIR significantly. The optimized anesthetic maintenance that differed from the unoptimized one in higher nociceptive defense had a considerable impact on the manifestation of SIR. Low molecular-weight heparins and preoperative hyperv-olemic hemodilution with hydroxyethyl starch preparations positively affected the study indices. The observed SIR belonged to the second stage of release of the small amount of mediators into systemic circulation. The transition of SIR to the third stage of inflammatory reaction generalization was suggested by changes in other monitored parameters, simultaneously informing about this or that degree of multiple organ dysfunction. Conclusion. Laparoscopic surgical intervention, multicom-ponent preoperative sedation, preventive preoperative analgesia with nonsteroidal anti-inflammatory drugs, prevention of microcirculatory disorders with low molecular-weight heparins, preoperative hypervolemic hemodilution with hydroxyethyl starch, and use of the loading doses of opioids in the period of induction to anesthesia in combination with propofol lower the level of a systemic inflammatory response

    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.

  1. The Value of Fecal Markers in Predicting Relapse in Inflammatory Bowel Diseases

    Full Text Available The inflammatory bowel diseases (IBDs are lifelong chronic illnesses that place an immense burden on patients. The primary aim of therapy is to reduce disease burden and prevent relapse. However, the occurrence of relapses is often unpredictable. Current disease monitoring is primarily by way of clinical indices, with relapses often only recognized once the inflammatory episode is established with subsequent symptoms and gut damage. The window between initial upregulation of the inflammatory response and the recognition of symptoms may provide an opportunity to prevent the relapse and associated morbidity. This review will describe the existing literature surrounding predictive indicators of relapse of IBD with a specific focus on fecal biomarkers. Fecal biomarkers offer promise as a convenient, non-invasive, low cost option for disease monitoring that is predictive of subsequent relapse. To exploit the potential of fecal biomarkers in this role, further research is now required. This research needs to assess multiple fecal markers in context with demographics, disease phenotype, genetics, and intestinal microbiome composition, to build disease behavior models that can provide the clinician with sufficient confidence to intervene and change the long-term disease course.

    Full Text Available Considering the limited knowledge regarding the effects of n-3 and n-6 PUFAs on the inflammatory response during physical activity, we aimed to evaluate the level of pro- and anti-inflammatory cytokines in young soccer players before and after a maximal physical load test at the beginning and end of a two-month training process. The study included 75 young footballers from Football School “Kragujevac,” who were followed during the two-month training programme. The subjects were divided into the following groups: 1 control group (consumed a standard diet; 2 group that consumed fish oil (2500 mg of n-3 PUFAs per day; 3 group that consumed nutritional sunflower oil (2500 mg of n-6 PUFAs daily. The maximal progressive exercise test was performed using a treadmill belt. Venous blood samples were drawn 4 times for the determination of cytokine levels (IL-6 and TNF-α: before and after the exercise load test before the two-month training programme (initial measurement and immediately before and after the exercise load test after the two-month training programme (control measurement. Supplementation with fish oil (n-3 has been associated with reduced levels of IL-6 compared with the initial values. After an acute bout of exercise, n-3 PUFAs did not show a significant effect on inflammatory marker dynamics, whereas n-6 PUFAs slightly stimulated the production of TNF-α.

    Augmented reality (AR) has recently gained significant attention. The previous AR techniques usually need a fiducial marker with known geometry or objects of which the structure can be easily estimated such as cube. Placing a marker in the workspace of the user can be intrusive. To overcome this limitation, we present an AR system using invisible markers which are created/drawn with an infrared (IR) fluorescent pen. Two cameras are used: an IR camera and a visible camera, which are positioned in each side of a cold mirror so that their optical centers coincide with each other. We track the invisible markers using IR camera and visualize AR in the view of visible camera. Additional algorithms are employed for the system to have a reliable performance in the cluttered background. Experimental results are given to demonstrate the viability of the proposed system. As an application of the proposed system, the invisible marker can act as a Vision-Based Identity and Geometry (VBIG) tag, which can significantly extend the functionality of RFID. The invisible tag is the same as RFID in that it is not perceivable while more powerful in that the tag information can be presented to the user by direct projection using a mobile projector or by visualizing AR on the screen of mobile PDA.

    Background: Recent studies have repeatedly shown weak correlations among lung function parameters, atopy, exhaled nitric oxide level (FeNO), and airway inflammatory markers, suggesting that they are non-overlapping characteristics of asthma in adults. A study was undertaken to determine, using factor analysis, whether the above features represent separate dimensions of childhood asthma. Methods: Clinically stable asthmatic patients aged 7–18 years underwent spirometric testing, methacholine bronchial challenge, blood sampling for atopy markers and chemokine levels (macrophage derived chemokine (MDC), thymus and activation regulated chemokine (TARC), and eotaxin), FeNO, and chemokines (MDC and eotaxin) and leukotriene B4 measurements in exhaled breath condensate (EBC). Results: The mean (SD) forced expiratory volume in 1 second (FEV1) and FeNO of 92 patients were 92.1 (15.9)% predicted and 87.3 (65.7) ppb, respectively. 59% of patients received inhaled corticosteroids. Factor analysis selected four different factors, explaining 55.5% of total variance. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.587. Plasma total and specific IgE levels, peripheral blood eosinophil percentage, and FeNO loaded on factor 1; plasma TARC and MDC concentrations on factor 2; MDC, eotaxin and leukotriene B4 concentrations in EBC on factor 3; and plasma eotaxin concentration together with clinical indices including body mass index and disease severity score loaded on factor 4. Post hoc factor analyses revealed similar results when outliers were excluded. Conclusions: The results suggest that atopy related indices and airway inflammation are separate dimensions in the assessment of childhood asthma, and inflammatory markers in peripheral blood and EBC are non-overlapping factors of asthma.

    Full Text Available Inflammatory markers are elevated in patients with dementia. Evidence for an association between inflammation and cognitive function in dementia-free individuals is sparse, inconsistent, and predominantly restricted to the elderly. Assessment of inflammatory markers in young adults as predictors of cognitive function in midlife, well before the onset of overt dementia, is lacking. Furthermore, rarely has the relation with longitudinal change in inflammatory markers been examined.To examine the association of the inflammatory markers C-reactive protein (CRP, fibrinogen, white blood cell count (WBC and GlycA, a novel NMR-determined biomarker of systemic inflammation, measured in young adulthood and of GlycA change over 13 years follow-up with cognitive function in midlife.507 participants of the Jerusalem Lipid Research Clinic (LRC study were assessed at 3 time points over 18-22 years. First, the inflammatory variables GlycA, CRP, fibrinogen, and WBC were measured in blood samples drawn at ages 28-32. Then, in blood samples drawn a mean 13 years later (range, 12-16 years at ages 41-46, GlycA was again measured (in 484 individuals. Subsequently at ages 48-52, on average 7 years later, global cognitive function and its five specific component domains were assessed with a NeuroTrax computerized test battery. Multiple regression and multivariable logistic models were applied.Inverse unadjusted associations were shown for baseline levels and longitudinal change in inflammatory markers and measures of cognition. Multiple regression models were adjusted for age at cognitive assessment, sex, socio-demographic characteristics, baseline measures of leisure-time vigorous activity, smoking status and body mass index (BMI at ages 28-32, change in smoking status and BMI between ages 28-32 and 41-46, and depression assessed at the time of cognitive testing. The highest quintile of GlycA change, but not the baseline inflammation measures, was inversely related to

    Full Text Available The aim of this study is to evaluate the role of cholinesterases as an inflammatory marker in acute and chronic infection by Trypanosoma evansi in rabbits experimentally infected. Twelve adult female New Zealand rabbits were used and divided into two groups with 6 animals each: control group (rabbits 1-6 and infected group (rabbits 7-12. Infected group received intraperitoneally 0.5 mL of blood from a rat containing 108 parasites per animal.

Increased activity (P0.05 was observed in the encephalic structures. The increased activities of AChE and BChE probably have a pro-inflammatory purpose, attempting to reduce the concentration of acetylcholine, a neurotransmitter which has an anti-inflammatory property. Therefore, cholinesterase may be inflammatory markers in infection with T. evansi in rabbits.O objetivo do presente estudo é avaliar o papel das colinesterases como marcadores inflamatórios nas fases aguda e crônica da infecção por T. evansi em coelhos infectados experimentalmente.

    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.

    Diabetic foot ulcerations have been extensively reported as vascular complications of diabetes mellitus associated with a high degree of morbidity and mortality. Diabetic foot syndrome (DFS), as defined by the World Health Organization, is an “ulceration of the foot (distally from the ankle and including the ankle) associated with neuropathy and different grades of ischemia and infection”. Pathogenic events able to cause diabetic foot ulcers are multifactorial. Among the commonest causes of this pathogenic pathway it’s possible to consider peripheral neuropathy, foot deformity, abnormal foot pressures, abnormal joint mobility, trauma, peripheral artery disease. Several studies reported how diabetic patients show a higher mortality rate compared to patients without diabetes and in particular these studies under filled how cardiovascular mortality and morbidity is 2-4 times higher among patients affected by type 2 diabetes mellitus. This higher degree of cardiovascular morbidity has been explained as due to the observed higher prevalence of major cardiovascular risk factor, of asymptomatic findings of cardiovascular diseases, and of prevalence and incidence of cardiovascular and cerebrovascular events in diabetic patients with foot complications. In diabetes a fundamental pathogenic pathway of most of vascular complications has been reported as linked to a complex interplay of inflammatory, metabolic and procoagulant variables. These pathogenetic aspects have a direct interplay with an insulin resistance, subsequent obesity, diabetes, hypertension, prothrombotic state and blood lipid disorder. Involvement of inflammatory markers such as IL-6 plasma levels and resistin in diabetic subjects as reported by Tuttolomondo et al confirmed the pathogenetic issue of the a “adipo-vascular” axis that may contribute to cardiovascular risk in patients with type 2 diabetes. This “adipo-vascular axis” in patients with type 2 diabetes has been reported as characterized

    Changes in inflammatory marker concentrations or activity can be used to monitor health and disease condition of domestic animals but have not been applied with the same frequency to wildlife. We measured concentrations or activity of six inflammatory markers (ceruloplasmin, haptoglobin, mannan-binding lectin-dependent complement [MBL/complement], unsaturated iron-binding capacity (UIBC) and total iron-binding capacity (TIBC), and plasma iron) in apparently healthy and sick or injured Red-tailed Hawks (Buteo jamaicensis). Haptoglobin and ceruloplasmin activities were consistently elevated in sick or injured hawks (2.1 and 2.5 times higher, respectively), and plasma iron concentrations decreased (0.46 times lower), relative to those of healthy birds. There were no differences between healthy and unhealthy hawks in TIBC and UIBC concentrations or MBL/complement activity. Therefore, haptoglobin, ceruloplasmin, and plasma iron would be useful inclusions in a panel of inflammatory markers for monitoring health in raptors.

    To assess relationships of inflammatory markers and 2 related clinical factors with blood culture results, we retrospectively investigated inpatients' blood culture and blood chemistry findings that were recorded from January to December 2014 using electronic medical records and analyzed the data of 852 subjects (426 culture-positive and 426 culture-negative). Results suggested that the risk of positive blood culture statistically increased as inflammatory marker levels and the number of related factors increased. Concerning the effectiveness of inflammatory markers, when the outcome definition was also changed for C-reactive protein (CRP), the odds ratio had a similar value, whereas when the outcome definition of blood culture positivity was used for procalcitonin (PCT), the greatest effectiveness of that was detected. Therefore, the current results suggest that PCT is more useful than CRP as an auxiliary indication of bacterial infection. Copyright © 2016 Elsevier Inc. All rights reserved.

    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.

The aim of our study was to assess the predictive value of preoperative inflammatory markers, such as the neutrophil–lymphocyte ratio (NLR, platelet–lymphocyte ratio, red cell distribution width (RDW, and mean platelet volume, for survival in breast cancer patients. In total, 608 breast cancer patients operated on between January 2009 and December 2011 were included in this observational study. The association between preoperative inflammatory markers and survival outcomes was analyzed. Patients with high NLR (>2.57 or high RDW (>13.45% showed a significantly lower overall survival rate than those with lower NLR (≤2.57 or lower RDW (≤13.45%. NLR and RDW, along with node stage and molecular subtypes, were independent prognostic factors. There was a significant survival difference according to NLR in the luminal A and triple-negative subtypes (93.3% versus 99.3%, P=0.001; 68.8% versus 95.1%, P=0.000, respectively. The triple-negative subtype was the only subtype in which higher RDW patients showed significantly poor prognosis (81.3% versus 95.5%, P=0.025. Pre-operation NLR and RDW is a convenient, easily measured prognostic indicator for patients with breast cancer, especially in patients with the triple-negative subtype.

    Full Text Available Background: This study aimed to investigate whether magnesium supplementation might affect serum magnesium, high sensitive C-reactive protein (hs-CRP, plasma fibrinogen, and interleukin 6 (IL-6 levels in healthy middle-aged overweight women. The relationships, if any, between serum magnesium and the inflammatory markers were also examined cross-sectionally in the entire participants at the beginning of the study. Materials and Methods: This double-blinded, placebo-controlled, randomized trial included 74 middle-aged overweight women. Participants were randomly assigned to receive either 250 mg magnesium as magnesium oxide or placebo daily for 8 weeks. Serum magnesium, hs-CRP, fibrinogen and IL-6 concentrations were measured before and after the intervention. Results: Serum magnesium was found to be inversely correlated with hs-CRP (r s =−0.22, P=0.05 in the entire participants at baseline. Serum hs-CRP declined significantly in both groups as compared with baseline values (median change=0.8 mg/L; P Magnesium= 0.03, P Placebo 0.001. Plasma fibrinogen decreased significantly, by 9%, in the magnesium group at the end of week 8 compared to baseline (P=0.001. Mean concentration of IL-6 was significantly increased in the magnesium group comparing the baseline value(P=0.001. However hs-CRP, fibrinogen and IL-6 levels at week 8 or any changes during the study were not statistically different between the two groups. Serum magnesium showed no significant changes in any groups. Conclusions: Serum magnesium had a significant inverse correlation with hs-CRP. In the present study, magnesium as magnesium oxide, 250 mg/day, for 8 weeks did not significantly attenuate inflammatory markers in the magnesium group as compared to the placebo.

    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.

    Objectives: To evaluate the diabetic patients for cardiac risk by measuring oxidative stress and inflammatory markers in relation with glycaemic control. Methodology: A total of 140 subjects were included in this case-control study, comprising of 70 diabetic patients with coronary heart disease (CHD) and an equal number, age and sex matched controls. The patients were non-alcoholic and had age >40 years, BMI < 30 kg/m/sup 2/ and glycated hemoglobin (HbA1c) 7-10%. Serum total cholesterol (TC) and gamma glutamyltransferase (GGT) were analyzed on selectra-E auto analyzer. Serum nitrate was measured at 540 nm on ELISA. HbA1c on was analyzed by using Human kit. Serum high sensitivity C-reactive protein (hS-CRP) was analyzed on immulite 1000. Results: Patients mean age was 51 (range 40-73) years. Diabetic patients had significantly elevated median of HbA1c (7.9 vs 4.9), hS CRP (6.0 vs 2.12), TC (5.95 vs 4.45), nitrate (19.20vs 10.70) and GGT (29.50 vs 22.50) as compared to controls (p< 0.001). HbA1c showed a positive correlation (p <0.001) with hS-CRP (r=0.49), TC (r=0.69), nitrate (r=0.41) and GGT (r=0.30). Conclusion: Oxidative stress and inflammatory markers should be used in addition to HbA1c for assessment of increased cardiac risk in un-controlled diabetic patients because of accelerated atherosclerosis due to free radical injury.

    Several studies have been focusing on the effect of omega-3 polyunsaturated fatty acids on modulation of inflammatory markers in several cardiopathies. Although immunoregulatory dysfunction has been associated to the chronic cardiac involvement in Chagas disease, there is no study examining the effects of omega-3 supplementation in these patients. We investigated the effects of omega-3 PUFAs on markers of inflammation and lipid profile in chronic Chagas cardiomyopathy patients. The present study was a single-center double-blind clinical trial including patients with chronic Chagas cardiomyopathy. Patients were randomly assigned to receive omega-3 PUFAs capsules (1.8g EPA and 1.2g DHA) or placebo (corn oil) during an 8-week period. Cytokines, fasting glucose, lipid, and anthropometric profiles were evaluated. Forty-two patients (23 women and 19 men) were included in the study and there were only two losses to follow-up during the 8-week period. Most of sociodemographic and clinical characteristics were similar between the groups at baseline, except for the cytokines IL-1β, IL-6, IL-8, IL-10, IL-17α, and IFNγ. The omega-3 PUFAs group demonstrated greater improvements in serum triglycerides (-21.1 vs. -4.1; p = 0.05) and IL-10 levels (-10.6 vs. -35.7; p = 0.01) in comparison to controls after 8 weeks of intervention. No further differences were observed between groups. Omega-3 PUFAs supplementation may favorably affect lipid and inflammatory profile in chronic Chagas cardiomyopathy patients, demonstrated by a decrease in triglycerides and improvements on IL-10 concentration. Further studies examining the clinical effects of omega-3 fatty acids supplementation in chronic Chagas cardiomyopathy are necessary. NCT01863576.

    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.

    This systematic review aims to evaluate randomised controlled trials (RCTs) investigating the effect of vitamin D supplementation on endothelial function and inflammation in adults. An electronic search of published randomised controlled trials, using Cochrane, Pubmed and Medline databases was conducted, with the search terms related to vitamin D and endothelial function. Inclusion criteria were RCTs in adult humans with a measure of vitamin D status using serum/plasma 25(OH)D and studies which administered the intervention through the oral route. Among the 1107 studies retrieved, 29 studies met the full inclusion criteria for this systematic review. Overall, 8 studies reported significant improvements in the endothelial/inflammatory biomarkers/parameters measured. However, in 2 out of the 8 studies, improvements were reported at interim time points, but improvements were absent post-intervention. The remaining 21 trial studies did not show significant improvements in the markers of interest measured. Evidence from the studies included in this systematic review did not demonstrate that vitamin D supplementation in adults, results in an improvement in circulating inflammatory and endothelial function biomarkers/parameters. This systematic review does not therefore support the use of vitamin D supplementation as a therapeutic or preventative measure for CVD in this respect. Crown Copyright © 2017.

    Stroke is a pathological condition associated with an enhanced inflammatory response that has a multifactorial etiology. We evaluated the dynamic of plasma concentrations of IL-1α, IL-6, IL-8, TNF-α, soluble form of intercellular adhesion molecule 1, and lipoprotein (a) [Lp(a)] during the rehabilitation of post-acute stroke patients (n = 20), in parallel with control subjects (n = 24). Stroke patients had significantly increased concentrations of IL-6, TNF-α, and Lp(a) when compared to healthy controls. It was found that the changes in the IL-6, IL-8, and TNF-α concentrations associated with the pathological condition were statistically significant (χ2 = 4.81, p = 0.028, χ2 = 10.40, p = 0.005 and χ2 = 6.73, p = 0.034, respectively). The decrease of Lp(a) during the rehabilitation had statistical significance (p = 0.043), while the decrease of IL-1α had marginal significance (p = 0.071). IL-1α, TNF-α, and Lp(a) concentrations were significantly negatively correlated with the Barthel index values, suggesting that the decrease of these inflammatory markers was beneficial for patients' recovery.

    Intratesticular injection (ITI) of sodium chloride (NaCl) is efficient for chemical castration of young calves, but its effects on calves welfare are unknown. Two experiments were conducted to evaluate the effects of ITI of 20% NaCl on stress and inflammatory markers in calves less than 20 days old and to assess the efficiency of ITI of 30% NaCl in 5 months old calves. In Experiment 1, control calves were only restrained and compared to calves submitted to castration through surgery (SC) and ITI with 20% NaCl (n = 9/group). No differences were observed for the eye corner temperature measured by thermography from 60 s before to 60 s after the procedures (P > 0.05). In the SC group, acute serum cortisol levels increased at 30 and 60 min after the procedure, but increased levels in the ITI group occurred only at 30 min (P  0.05). Scrotal temperature was higher at D1 in the SC group than for the other groups, but lowest at D4 compared to the control (both P castration through ITI of 20% NaCl in young calves was followed by slight stress and inflammatory responses compared to surgical castration. However, ITI of 30% NaCl was ineffective for chemical castration of 5 months old calves. Copyright © 2016 Elsevier Inc. All rights reserved.

    Inflammation is a major risk factor for cardiovascular complications. Magnesium sulfate (MgSO4) has anti-inflammatory actions. Therefore we investigated the effects of levothyroxine and MgSO4 on inflammatory markers as C-reactive protein (CRP), interleukin-6, tumor necrosis factor-α (TNF-α), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) in hypothyroid rats. Sixty male rats were divided into 6 groups; normal, normal + MgSO4, hypothyroidism, hypothyroidism + levothyroxine, hypothyroidism + MgSO4, and hypothyroidism + levothyroxine + MgSO4. Thyroxine, triiodothyronine, and thyroid-stimulating hormone (TSH), CRP, interleukin-6, TNF-α, ICAM-1, and VCAM-1 were measured in all rats. Hypothyroidism significantly increased TSH, CRP, interleukin-6, TNF-α, ICAM-1, and VCAM-1 and decreased triiodothronine and thyroxine. Treatment of hypothyroid rats with levothyroxine or MgSO4 significantly decreased CRP, interleukin-6, TNF-α, ICAM-1, and VCAM-1. Combined therapy of hypothyroid rats with levothyroxine and MgSO4 significantly decreased CRP, interleukin-6, TNF-α, ICAM-1, and VCAM-1 compared with hypothyroid rats either untreated or treated with levothyroxine or MgSO4. This study demonstrates that hypothyroid rats have chronic low grade inflammation, which may account for increased risk of cardiovascular diseases. Combined levothyroxine and MgSO4 is better than levothyroxine or MgSO4 alone in alleviating the chronic low grade inflammatory status and therefore reducing the risk of cardiovascular diseases in hypothyroid animals.

    The goal of this study was to examine the associations of maternal weight status before, during, and after pregnancy with breast milk C-reactive protein (CRP) and interleukin 6 (IL-6), two bioactive markers of inflammation, measured at 1 and 3 months post partum. Participants were 134 exclusively breastfeeding mother-infant dyads taking part in the Mothers and Infants Linked for Health (MILK) study, who provided breast milk samples. Pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) were assessed by chart abstraction; postpartum weight loss was measured at the 1- and 3-month study visits. Linear regression was used to examine the associations of maternal weight status with repeated measures of breast milk CRP and IL-6 at 1 and 3 months, after adjustment for potential confounders. Pre-pregnancy BMI and excessive GWG, but not total GWG or postpartum weight loss, were independently associated with breast milk CRP after adjustment (β = 0.49, P milk CRP. The consequences of infants receiving varying concentrations of breast milk inflammatory markers are unknown; however, it is speculated that there are implications for the intergenerational transmission of disease risk. © 2017 The Obesity Society.

    Haemostatic and inflammatory markers have been hypothesised to mediate the relationship of social class and cardiovascular disease (CVD). We investigated whether a range of inflammatory/haemostatic markers are associated with social class independent of chronic diseases and behavioural risk factors in a population-based sample of 2682 British men aged 60-79 without a physician diagnosis of CVD, diabetes or musculoskeletal disease requiring anti-inflammatory medications. Men in lower social classes had higher mean levels of C-reactive protein, fibrinogen, interleukin-6, white blood cell count, von Willebrand factor (vWF), factor VIII, activated protein C (APC) resistance, plasma viscosity, fibrin D-dimer and platelet count, compared to higher social class groups; but not of tissue plasminogen activator antigen, haematocrit or activated partial prothrombin time. After adjustment for behavioural risk factors (smoking, alcohol, physical activity and body mass), the associations of social class with vWF, factor VIII, APC resistance, plasma viscosity, and platelet count though weakened, remained statistically significant, while those of other markers were considerably attenuated. In this study of older men without CVD, the social gradient in inflammatory and haemostatic markers was substantially explained by behavioural risk factors. The effect of socio-economic gradient on the factor VIII-vWF complex, APC resistance, plasma viscosity and platelet count merits further study.

    Cardiopulmonary bypass is associated with systemic inflammatory response. Steroids suppress this response, although the therapeutic evidence remains controversial. We hypothesised that intravenous steroids in children undergoing open-heart surgery would decrease inflammation leading to better early post-operative outcomes. We conducted a randomised controlled trial to evaluate the trends in the levels of immunomodulators and their effects on clinical parameters. To assess the effects of intravenous steroids on early post-operative inflammatory markers and clinical parameters in children undergoing open-heart surgery. A randomised controlled trial involving 152 patients, from one month up to 18 years of age, who underwent open-heart surgery for congenital heart disease from April 2010-2012 was carried out. Patients were randomised and administered either three scheduled intravenous pulse doses of dexamethasone (1 mg/kg) or placebo. Blood samples were drawn at four time intervals and serum levels of inflammatory cytokines - Interleukin-6, 8, 10, 18, and tumour necrosis factor-alpha - were measured. Clinical parameters were also assessed. Blood cytokine levels were compared between the dexamethasone (n=65) and placebo (n=64) groups. Interleukin-6 levels were lower at 6 and 24 hours post-operatively (p<0.001), and Interleukin-10 levels were higher 6 hours post-operatively (p<0.001) in the steroid group. Interleukin-8, 18, and tumour necrosis factor-alpha levels did not differ between the groups at any time intervals. The clinical parameters were similar in both the groups. Dexamethasone caused quantitative suppression of Interleukin-6 and increased Interleukin-10 activation, contributing to reduced immunopathology, but it did not translate into clinical benefit in the short term.

    Objective: To study the association of inflammatory markers with physical activity, family history and other complications among patients of diabetic retinopathy. Study Design: Cross sectional comparative study. Place and Duration of Study: Department of Biochemistry and Molecular Biology, Army Medical College, Rawalpindi in collaboration with Armed Forces Institute of Ophthalmology (AFIO) and Military Hospital Laboratories, Rawalpindi from Jan 2016 to Jun 2016. Material and Methods: A total of 90 diagnosed patients of diabetic retinopathy of ages 40-70 years were enrolled from Armed Forces Institute of Ophthalmology, Rawalpindi. Their inflammatory markers (ESR and CRP) were assessed and their levels were compared with their physical activity, family history and other complications of diabetes already developed in them. These were then compared with those of 90 normal healthy controls enrolled from general population using independent student's t test and one way Anova test for scale variables and Chi square test for nominal variables. Results: Both patients and controls were age and gender matched with mean age of 60 +- 8.9 years in patients and 59 +- 13.02 years in controls. Among 90 patients enrolled 51(56.7 percent) were males and 39 (43.3) were females. And among 90 controls 49 (54.4 percent) were males and 41(45.6 percent) were females. An inverse association was observed between inflammatory markers and physical activity with ap-value of 0.001. On the contrary a strong positive association was observed between inflammatory markers and family history and complications of diabetes with a p-value 0.001. Conclusion: There is an inverse association of inflammatory markers with physical activity and a direct association of these with family history and complications of diabetes among patients of diabetic retinopathy.

    Osteoarthritis is the most prevalent arthritic condition. Systemic inflammatory cytokines appear to have an important role in the onset and maintenance of the disease. Sleep disturbances are prevalent in osteoarthritis and associated with alterations in systemic inflammatory cytokines, suggesting a common pathophysiology across these conditions. A comparative investigation of the effects of insomnia disorder and osteoarthritis on pain-evoked cytokine responses has yet to be undertaken. We examined the influence of symptomatic knee osteoarthritis and insomnia disorder on resting C-reactive protein (CRP), interleukin (IL)-6, and IL-10 levels, and pain-evoked IL-6 and IL-10 responses. Participants were N=117 older adults (mean age=59.7years; 61.8% women) rigorously evaluated for knee osteoarthritis and insomnia disorder using established diagnostic guidelines. Results revealed no association of osteoarthritis or insomnia disorder with CRP. Resting IL-6 was greater in osteoarthritis participants versus those without osteoarthritis, although this association was largely attributable to BMI. IL-10 was highest among participants with osteoarthritis or insomnia disorder. Growth curve modeling revealed that participants with insomnia disorder had greater pain-evoked IL-6 responses than participants without insomnia disorder or osteoarthritis. These findings highlight the utility of laboratory pain testing methods for understanding individual differences in inflammatory cytokines. Moreover, our findings provide evidence for amplified pain-evoked pro-inflammatory cytokine reactivity among older adults with clinically diagnosed insomnia disorder, even after controlling for individual differences in BMI and age. Additional research will be required determine whether an amplified pain-related cytokine response contributes to OA, and possibly other age-related disease, associated with insomnia disorder.

    Epidemiological studies have reported that vitamin D deficiency is associated with inflammatory disease. Smoking is a well-known risk factor for inflammation. However, few studies have investigated the interactive effect of vitamin D deficiency and smoking on inflammation. This study aims to investigate the interaction of vitamin D and smoking with inflammatory markers in the urban elderly. We used data from the Korean Elderly Environmental Panel Study, which began in August 2008 and ended in August 2010, and included 560 Koreans ≥60 years old living in Seoul. Data was collected via questionnaires that included items about smoking status at the first visit. Vitamin D levels, high-sensitivity C-reactive protein (hs-CRP), and white blood cell (WBC) counts were repeatedly measured up to three times. The association of vitamin D and hs-CRP was significant after adjusting for known confounders (β=-0.080, p=0.041). After separate analysis by smoking status, the association of vitamin D deficiency and hs-CRP in smokers was stronger than that in nonsmokers (smokers: β=-0.375, p=0.013; non-smokers: β=-0.060, p=0.150). Smoking status was an effect modifier that changed the association between vitamin D deficiency and hs-CRP (interaction estimate: β=-0.254, p=0.032). Vitamin D was not significantly associated with WBC count (β=0.003, p=0.805). Vitamin D deficiency was associated with hs-CRP in the urban elderly. Smoking status was an effect modifier of this association. Vitamin D deficiency was not significantly associated with WBC count.

    Full Text Available Preeclampsia represents a pathological state that is specific to regnancy, is characterized by high blood pressure de novo and significant proteinuria and appears after 20 weeks of pregnancy. The continuously increasing mortality caused by preeclampsia in our country totally justifies the fact that all efforts are directed towards primary and secondary prevention of the disease and underlines the necessity of urgent intervention at population level, together withthe implementation of a screening programme that is able to reduce the impact of this condition on the mother and the baby. The cases were gathered between 2003 and 2014. The patients were selected by studying the observation charts of the pregnant women hospitalized in ”Cuza Vodă” Clinical Hospital of Obstetrics and Gynecology Iaşi, having a pregnancy over 20 weeks, who came for a specialized consult and who were harvested CRP, without an infectious context or prematurely and spontaneously ruptured membranes. The comparison of the lab markers for the pregnantwomen with severe preeclampsia, depending on the plasmatic level of CRP over 12 mg/l, showed significantly higher values of fibrinogen, LDH, GOT, GPT, serum blood urea nitrogen, creatinine and urine proteins, while the mean number of white cells was significantly reduced (p<0,05. The study confirms the change in the inflammatory process markers, the hepatic and kidney function, associated with a high plasmatic level of CRP for pregnant women with severe preeclampsia.

    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 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.

    To investigate that inflammatory markers can predict accurately the prognosis of hepatocelluar carcinoma (HCC) patients in living-donor liver transplantation (LDLT). From October 2000 to November 2011, 224 patients who underwent living donor liver transplantation for HCC at our institution were enrolled in this study. We analyzed disease-free survival (DFS) and overall survival (OS) after LT in patients with HCC and designed a new score model using pretransplant neutrophil-lymphocyte ratio (NLR) and C-reactive protein (CRP). The DFS and OS in patients with an NLR level ≥ 6.0 or CRP level ≥ 1.0 were significantly worse than those of patients with an NLR level < 6.0 or CRP level < 1.0 (P = 0.049, P = 0.003 for NLR and P = 0.010, P < 0.001 for CRP, respectively). Using a new score model using the pretransplant NLR and CRP, we can differentiate HCC patients beyond the Milan criteria with a good prognosis from those with a poor prognosis. Combined with the Milan criteria, new score model using NLR and CRP represent new selection criteria for LDLT candidates with HCC, especially beyond the Milan criteria.

    Low-grade inflammation may provide a mechanism linking obesity with cardiometabolic diseases and is also related to aerobic fitness (VO2max) and physical activity (PA). However, the longitudinal associations between these factors over the course of childhood and young adolescence are yet....... PA was measured for four consecutive days (Actigraph). VO2max was directly measured. Fasting blood samples were analyzed for inflammatory markers. RESULTS: Significant correlations were found between S4SF at age 6 and C-reactive protein (CRP) level at age 13 for both boys and girls (r=0.330 and 0.......293 respectively, p=0.0001). S4SF at age 6 was related to interleukin-6 (IL6) level at age 13 only for boys (r=0.165, p=0.019). Children in the highest tertile of S4SF at age 6 had an odds ratio of 3.68 (p=0.0001) being in the highest tertile of CRP at age 13, compared to the lowest tertile. VO2max at age 6...

    Full Text Available Prostate cancer is the second leading cause of cancer-related death in men. The present study was carried out to investigate the radiation response of serum cytokines and oxidative markers to find out if these novel biomarkers have significant applications regarding radiation outcome in prostate cancer patients. Significant elevations of prostatic specific antigen (PSA, asymmetric dimethyl arginine (ADMA and nitric oxide (NO were recorded in cancer prostate patients at the time of diagnosis compared to controls. Patients were subjected to radiotherapy post prostatectomy with a total dose of 66 Gy in 33 fractions (5 sessions/week for 7 weeks. At the end of the seventh week post radiotherapy, ADMA levels were accentuated while the levels of PSA and NO were lower than before therapy. The level of inflammatory cytokines (interleukins IL-4, IL-5 and interferon-gamma in post radiation therapy patients were significantly elevated compared to both controls and prostate cancer patients. A significant inverse correlation was observed in prostate cancer patients between ADMA and NO. Moreover, a significant inverse correlation in post radiation therapy patients was observed between IL-5 and PSA. These results are highly suggestive that there is a specific cytokine response in patients undergoing curative radiotherapy for prostate cancer.

Subjects received authentic (cases or sham (controls acupuncture for 6 weeks in combination with a low-calorie diet. In the following 6 weeks, they received the low-calorie diet alone. Subjects were assessed at the beginning, 6 and 12 weeks later. Heat shock protein (Hsps-27, 60, 65, 70 antibody titers and high sensitivity C-reactive protein (hs-CRP levels were also assessed. A significant reduction in measures of adiposity and improvement in lipid profile were observed in both groups, but the levels of anti-Hsp-antibodies decreased in cases only. A reduction in anthropometric and lipid profile in cases were sustained in the second period, however, only changes in lipid profile were observed in the control group. Anti-Hsp-antibodies and hs-CRP levels continued to be reduced in cases but in controls only the reduction in hs-CRP remained. Changes in anthropometric parameters, lipid profile, and anti-Hsp-antibodies were more evident in cases. Body acupuncture in combination with diet restriction was effective in enhancing weight loss and improving dyslipidemia.

    Full Text Available Abstract Background Systemic inflammation is linked to cardiovascular risk, but the influence of persistent pathogens, which are conventionally dichotomously categorized, on circulating levels of inflammatory markers is not clear. Antibody levels of pathogens have not been examined in relation to inflammation. Methods Using data from a subsample of the Multi-Ethnic Study of Atherosclerosis, we examined circulating levels of interleukin-6 (IL-6, C-reactive protein (CRP and fibrinogen in relation to five common persistent pathogens: cytomegalovirus, herpes simplex virus-1, Hepatitis A virus, Helicobacter pylori and Chlamydia pneumoniae. We tested the hypothesis that the number of seropositive pathogens (based on conventional cut-off points would not be as sensitive a marker of inflammation as immune response measured by antibody levels to pathogens. Results High antibody response to multiple pathogens showed graded and significant associations with IL-6 (p Conclusions High antibody response to pathogens was a more consistent marker of inflammatory outcomes compared to seropositivity alone and high antibody response to multiple pathogens was a stronger marker compared to any single pathogen.

    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.

    Lower socioeconomic position (SEP) has consistently been associated with poorer health. To explore potential biological embedding and the consequences of SEP experiences from early life to adulthood, we investigate how SEP indicators at different points across the life course may be related to a combination of 28 inflammation markers. Using blood-derived inflammation profiles measured by a multiplex array in 268 participants from the Italian component of the European Prospective Investigation into Cancer and Nutrition cohort, we evaluate the association between early life, young adulthood and later adulthood SEP with each inflammatory markers separately, or by combining them into an inflammatory score. We identified an increased inflammatory burden in participants whose father had a manual occupation, through increased plasma levels of CSF3 (G-CSF; β = 0.29; P = 0.002), and an increased inflammatory score (β = 1.96; P = 0.029). Social mobility was subsequently modelled by the interaction between father's occupation and the highest household occupation, revealing a significant difference between "stable Non-manual" profiles over the life course versus "Manual to Non-manual" profiles (β = 2.38, P = 0.023). Low SEP in childhood is associated with modest increase in adult inflammatory burden; however, the analysis of social mobility suggests a stronger effect of an upward social mobility over the life course.

    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.

    We hypothesized that breast tissue not involved by tumor in inflammatory breast cancer (IBC) patients contains intrinsic differences, including increased mammary stem cells and macrophage infiltration, which may promote the IBC phenotype. Normal breast parenchyma ≥ 5 cm away from primary tumors was obtained from mastectomy specimens. This included an initial cohort of 8 IBC patients and 60 non-IBC patients followed by a validation cohort of 19 IBC patients and 25 non-IBC patients. Samples were immunostained for either CD44 + CD49f + CD133/2 + mammary stem cell markers or the CD68 macrophage marker and correlated with IBC status. Quantitation of positive cells was determined using inForm software from PerkinElmer. We also examined the association between IBC status and previously published tumorigenic stem cell and IBC tumor signatures in the validation cohort samples. 8 of 8 IBC samples expressed isolated CD44 + CD49f + CD133/2 + stem cell marked cells in the initial cohort as opposed to 0/60 non-IBC samples (p = 0.001). Similarly, the median number of CD44 + CD49f + CD133/2 + cells was significantly higher in the IBC validation cohort as opposed to the non-IBC validation cohort (25.7 vs. 14.2, p = 0.007). 7 of 8 IBC samples expressed CD68 + histologically confirmed macrophages in initial cohort as opposed to 12/48 non-IBC samples (p = 0.001). In the validation cohort, the median number of CD68 + cells in IBC was 3.7 versus 1.0 in the non-IBC cohort (p = 0.06). IBC normal tissue was positively associated with a tumorigenic stem cell signature (p = 0.02) and with a 79-gene IBC signature (p stem cell signature and IBC-specific tumor signature. Collectively, these data suggest that IBC normal tissue differs from non-IBC tissue. Whether these changes occur before the tumor develops or is induced by tumor warrants further investigation.

    Full Text Available Inflammation is an important factor in the pathogenesis of atherosclerosis, and several markers of inflammation have been associated with an increased risk of cardiovascular events. Physical activity may lower the risk of coronary heart disease(CHD by mitigating inflammation. The aim of the study was to investigate the effects of aerobic exercise training on systemic inflammatory response in patients with stabile coronary artery disease participating in a cardiovascular rehabilitation exercise program. Male (n=29 and female (n=23 patients with stable coronary heart disease were recruited for this study. All patients were divided into two groups: group with regular aerobic physical training during cardiovascular rehabilitation program phase II along 3 weeks in rehabilitation center and 3 weeks after that in home of patients and sedentary lifestyle group. There were no significant differences in gender distribution among analyzed groups. Student’s t test showed no significant difference in mean age, waist circumference (OS and waist/hip ratio (WHR. Degree of obesity was measured by BMI, and there was a significant improvement in BMI in patients who underwent the six-week physical training compared to control group (p<0.05.Physical training during 6 weeks did not show any effects on leukocyte count and ICAM-1 levels compared to control group. The exercise training induced reduction in plasma CRP levels by 23.72%, p<0.001, and reduction in plasma VCAM-1 levels by Moderate aerobic exercise training resulted in a significant reduction of inflammatory state by decreasing CRP and VCAM-1 levels without significant body mass and visceral obesity reduction. The obtained results indicate that regular physical activity is clinically attractive in primary and secondary prevention of coronary heart diseases.

    The study discusses the role of antichitobioside carbohydrate antibody (ACCA), antilaminaribioside carbohydrate antibodies (ALCA), and antimannobioside carbohydrate antibodies (AMCA) in Central European patients with inflammatory bowel disease (IBD). Twohundred and seventy-two serum samples were used - 116 Crohn's disease (CD), 84 ulcerative colitis, and 72 healthy control samples. All samples were evaluated using enzyme-linked immunosorbent assay for the following four anticarbohydrate assays: ACCA, ALCA, AMCA, and anti-Saccharomyces cerevisiae antibodies (gASCA). gASCA antibodies showed the highest sensitivity (67%) for a CD diagnosis, followed by AMCA (31%), ACCA (27%), and ALCA (25%). Positivity of at least one of the four assays increased the overall sensitivity of antibody testing in CD up to 85.5%. Mean serum gASCA levels were significantly higher in CD patients who were younger at diagnosis and had a longer disease duration before blood sampling (PACCA, and ALCA) antibodies and CD location, behavior, age at onset, and disease duration was found; however, that sample size of some of our subgroups was probably too small to make firm conclusions on associations with all CD phenotypes. None of the assessed anticarbohydrate assays was predictive of colonic CD in patients in whom the distinction between CD and ulcerative colitis is not obvious using routine diagnostic methods. There was no relationship between the presence or concentration of anticarbohydrate antibodies and the inflammation measured by C-reactive protein levels. The use of a panel of anticarbohydrate antibodies may provide additional help in distinguishing IBD from non-IBD disease patterns. The addition of AMCA, ALCA, and ACCA assays as IBD serology markers improves the overall sensitivity of immunological examinations in IBD; however, anticarbohydrate assays are not helpful for predicting CD behavior.

The participants were divided into 4 groups: patients of group I took inhibitor of interleukin-1 (diacerein in combination with laser therapy and methotrexate; inhibitor of interleukin-1 in complex with methotrexate took patients from group II; group 3 — laser therapy + methotrexate and patients of group IV took only methotrexate. The efficacy of therapy we estimated in 6 months.Results: The constructed model surfaces indicated the decreased levels of IL-1, COMP and DAS 28 in group 1 till 6,68±0,37 pg/ml (p<0,001, 16,92±0,8 ng/ml х 10² (p<0,001 и 2,06±1,19 (p<0,05 accordingly in comparison with groups III and IV. Also the model surfaces revealed the interdependency of all these indicators. The control group (IV reacted to the treatment by decreasing the indicators as well. However, the dynamics of the changes was significantly less. In patients of groups I and II the levels of ESR and CRP decreased to 13,95±0,52* (*p<0,001 and 10,97±0,43* (*p<0,001; 16,53±0,63* (*p<0,001 and 12,81±0,77* (*p<0,001 accordingly.Conclusions: In comparison analysis we noted statistical significant advantages (p<0,01 of the use of diacerein with methotrexate regarding the dynamic of IL-1 and COMP, ESR, CRP in patient’s serum, which is accompanied by the reduction of basic disease activity on DAS 28.

    Full Text Available Background: This study aimed to examine the relationship between changes in systemic vitamin B12 concentrations with pro-inflammatory cytokines, anthropometric factors and biochemical markers of cardiometabolic risk in a Saudi population. Methods: A total of 364 subjects (224 children, age: 12.99 ± 2.73 (mean ± SD years; BMI: 20.07 ± 4.92 kg/m2 and 140 adults, age: 41.87 ± 8.82 years; BMI: 31.65 ± 5.77 kg/m2 were studied. Fasting blood, anthropometric and biochemical data were collected. Serum cytokines were quantified using multiplex assay kits and B12 concentrations were measured using immunoassay analyzer. Results: Vitamin B12 was negatively associated with TNF-α (r = −0.14, p < 0.05, insulin (r = −0.230, p < 0.01 and HOMA-IR (r = −0.252, p < 0.01 in all subjects. In children, vitamin B12 was negatively associated with serum resistin (r = −0.160, p < 0.01, insulin (r = −0.248, p < 0.01, HOMA-IR (r = −0.261, p < 0.01. In adults, vitamin B12 was negatively associated with TNF-α (r = −0.242, p < 0.01 while positively associated with resistin (r = 0.248, p < 0.01. Serum resistin was the most significant predictor for circulating vitamin B12 in all subjects (r2 = −0.17, p < 0.05 and in children (r2 = −0.167, p < 0.01 while HDL-cholesterol was the predictor of B12 in adults (r2 = −0.78, p < 0.05. Conclusions: Serum vitamin B12 concentrations were associated with pro-inflammatory cytokines and biochemical markers of cardiometabolic risks in adults. Maintaining adequate vitamin B12 concentrations may lower inflammation-induced cardiometabolic risk in the Saudi adult population.

    Our objective was to investigate interactions of psychological resources and socioeconomic status (SES)-as well as potential gender differences and the explanatory role of childhood and adult stress exposures, health behaviors, and negative and positive affect-in predicting markers of systemic inflammation. We utilized a sample of adults from the Midlife Development in the U.S. (MIDUS) study who provided biomarker data (N = 1,152). SES was operationalized as a composite of education, income, and occupational prestige, and the psychological resources construct was operationalized as a latent factor measured with optimism, perceived control, and self-esteem. Linear regression models examined these 2 factors and their interaction in predicting interleukin-6 (IL-6) and C-reactive protein (CRP) measured on average 2 years later, as well as 3-way interactions involving gender and the impact of covariate adjustment. Psychological resources interacted with SES in men (for IL-6: p low SES was moderately attenuated upon adjustment for negative affect. Socioeconomic status might modulate the linkage between psychological resources and systemic inflammation in men. At lower levels of SES, resources may be related to lower inflammation in part through lower negative affect. Associations with higher inflammation at higher SES add to growing evidence suggesting that adaptive psychological characteristics may be associated with markers of poorer physiological function under certain conditions.

    In the female genital tract, vaginal colposcopy, endometrial mucosal integrity and inflammatory mediators are potential in vivo biomarkers of microbicide and contraceptive safety. A randomized, blinded crossover trial of 18 subjects comparing effects of nonoxynol-9 vaginal gel (Gynol II; putative inflammatory gel), hydroxyethyl cellulose gel (HEC; putative inert gel) and no gel exposure on endometrial and vaginal epithelial integrity and endometrial and vaginal inflammatory markers [interleukin (IL) 1β, IL-6, IL-8, MCP-1, MIP-1α, MIP-1β, RANTES, tumor necrosis factor α, IL-1RA, IL-10, SLPI). Gynol II was associated with more vaginal lesions. No endometrial disruptions were observed across conditions. In the vagina, RANTES (p=.055) and IL-6 (p=.04) were higher after HEC exposure than at baseline. In the endometrium, IL-1β (p=.003) and IL-8 (p=.025) were lower after Gynol II cycles than after no gel. Gynol II and HEC may modulate inflammatory markers in the vagina and endometrium. How these changes relate to infection susceptibility warrants further study. Copyright © 2011 Elsevier Inc. All rights reserved.

    Immune sensitivity to wheat glutens and bovine milk caseins may affect a subset of individuals with bipolar disorder. Digested byproducts of these foods are exorphins that have the potential to impact brain physiology through action at opioid receptors. Inflammation in the gastrointestinal (GI) tract might accelerate exposure of food antigens to systemic circulation and help explain elevated gluten and casein antibody levels in individuals with bipolar disorder. We measured a marker of GI inflammation, anti-Saccharomyces cerevisiae antibodies (ASCA), in non-psychiatric controls (n = 207), in patients with bipolar disorder without a recent onset of psychosis (n = 226), and in patients with bipolar disorder with a recent onset of psychosis (n = 38). We compared ASCA levels to antibodies against gluten, casein, Epstein-Barr virus (EBV), herpes simplex virus 1 (HSV-1), influenza A, influenza B, measles, and Toxoplasma gondii. Elevated ASCA conferred a 3.5-4.4-fold increased odds ratio of disease association (age-, race-, and gender-corrected multinomial logistic regressions, p ≤ 0.00001) that was independent of type of medication received. ASCA correlated with food antibodies in both bipolar disorder groups (R(2)  = 0.29-0.59, p ≤ 0.0005), and with measles and T. gondii immunoglobulin G (IgG) in the recent onset psychosis bipolar disorder group (R(2)  = 0.31-0.36, p ≤ 0.004-0.01). Elevated seropositivity of a GI-related marker and its association with antibodies to food-derived proteins and self-reported GI symptoms suggest a GI comorbidity in at least a subgroup of individuals with bipolar disorder. Marker seroreactivity may also represent part of an overall heightened activated immune state inherent to this mood disorder. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available This study tested the effect of isoflavone supplementation in addition to combined exercise training on plasma lipid levels, inflammatory markers and oxidative stress in postmenopausal women. Thirty-two healthy and non-obese postmenopausal women without hormone therapy were randomly assigned to exercise + placebo (PLA; n = 15 or exercise + isoflavone supplementation (ISO; n = 17 groups. They performed 30 sessions of combined exercises (aerobic plus resistance over ten weeks and consumed 100 mg of isoflavone supplementation or placebo. Blood samples were collected after an overnight fast to analyze the lipid profile, interleukin-6 (IL-6, interleukin-8 (IL-8, superoxide dismutase (SOD, total antioxidant capacity (FRAP, and thiobarbituric acid reactive substances (TBARS, before and after ten weeks of the intervention. There were no differences in the changes (pre vs. post between groups for any of the inflammatory markers, oxidative stress markers or lipid profile variables. However, interleukin-8 was different between pre- and post-tests (p < 0.001 in both groups (Δ = 7.61 and 5.61 pg/mL as were cholesterol levels (p < 0.05, with no interaction between groups. The combination of isoflavone supplementation and exercise training did not alter oxidative stress markers in postmenopausal women, but exercise training alone may increase IL-8 and decrease total cholesterol levels.

    Full Text Available Although some studies revealed a positive relationship between vitamin D3 deficiency and inflammatory markers, there have been also many studies that failed to find this relationship. The aim of this large scaled study is to determine the association between the level of plasma 25 hydroxy vitamin D3 [25-(OH D3] and inflammatory markers in the general population without chronic kidney disease (CKD and in patients with CKD. Participants with simultaneously measured inflammatory markers and 25-(OH D3 levels were retrospectively analyzed (n=1897. The incidence of all-cause inflammation infection, hospitalization, chronic renal failure, and vitamin B12 deficiency was evaluated. The medians of serum creatinine levels in subjects without renal failure were lower in 25-(OH D3 deficient group. Patients with CKD were more likely to have vitamin D3 deficiency compared with normal GFR. 25-(OH D3 levels were associated with a greater incidence of all-cause hospitalization, hypoalbuminemia, and vitamin B12 deficiency. However, there was no relationship between inflammatory markers and vitamin D3 levels. In 25-(OH D3 deficient patients, inflammatory markers can be related to other inflammatory and infectious status such as malnutrition and cachexia. We believed that there must be a relationship between vitamin deficiency and inflammatory markers due to other causes than low 25-(OH D3 status.

Although mastitis has received significant scientific attention, one aspect of bovine mastitis has only been touched upon very briefly; the characterization of the recovery period and its potential for modulation. Hence, in order to increase the understanding of the recovery period...... after bovine mastitis and to create a basis for future facilitation of recovery, the present thesis focussed on two selected aspects of recovery; a behavioural as well as an inflammatory aspect, aiming to 1) describe the behaviour of dairy cows in the days before, during and after antibiotic treatment...... stabilisation within these measures and 3) investigate a possible relationship between behaviour, milk production and inflammatory markers during naturally occurring bovine mastitis and its early recovery. Overall, the focus was on dairy cows housed in free stalls with automatic milking systems (AMS). This type...

    Malnutrition and elevated inflammatory markers have a negative impact on clinical outcomes in cancer patients. Few studies have investigated the associations between inflammatory makers, nutritional status and survival. This study investigates the association between nutritional status, inflammatory markers and overall survival (OS) in patients with advanced cancer. This prospective cohort study recruited 114 adult patients from January 2007 to January 2010. It included patients diagnosed with advanced cancer, good Eastern Cooperative Oncology Group (ECOG) performance status 0-2, a prognosis of more than 3 months and had not received chemotherapy for advanced cancer prior to enrollment. Baseline data were collected prior to commencement of chemotherapy. Patients were followed up from the date of baseline nutritional assessment until the date of death or the date that data were last updated, whichever came first. Malnourished cancer patients had statistically significant higher concentrations of serum C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR) or modified Glasgow Prognostic Score (mGPS) prior to starting chemotherapy. In univariate analyses to predict survival, mGPS 1 or 2 had a hazard ratio (HR) of 1.81 (95 % confidence interval (CI) 1.13-2.89) and NLR ≥ 5 had a HR of 1.13 (95 % CI 1.08-4.60) and malnutrition (HR of 1.66 for Patient-Generated Subjective Global Assessment (PG-SGA) B (95 % CI 1.02-2.71), and HR for severely malnourished patients (PG-SGA C) was 2.73 (95 % CI 1.50-4.96). Inflammatory markers were statistically associated with malnutrition. Malnutrition and mGPS were significant independent predictors of overall survival in patients with advanced cancer.

    Pulse wave velocity (PWV) is thought to have different relationships with metabolic syndrome (MS) components, inflammatory markers, and oxidative stress, according to age. However, age-specific determinants of PWV have not yet been studied. We investigated age-dependent relationships among PWV and MS components, inflammatory markers, and oxidative stress. A total of 4,318 subjects were divided into 4 groups: 19-34 y (n=687), 35-44 y (n=1,413), 45-54 y (n=1,384), and 55-79 y (n=834). MS components, brachial-ankle PWV (baPWV), high-sensitivity C-reactive protein (hs-CRP), and oxidative stress markers were measured. There were age-related increases in MS, body mass index (BMI), waist circumference, systolic blood pressure (SBP), diastolic BP (DBP), triglycerides, glucose, hs-CRP, oxidized low-density lipoprotein (LDL), 8-epi-prostaglandin F 2α (8-epi-PGF 2α ), and baPWV. BaPWV was significantly associated with sex and elevated BP in the 19-34 y group; with age, sex, BMI, elevated BP and triglycerides in the 35-44 y group; with age, sex, elevated BP, fasting glucose, hs-CRP and oxidized LDL in the 45-54 y group; and with age, BMI, elevated BP, fasting glucose and oxidized LDL in the 55-79 y group. Our results show that age-related increases in baPWV are associated with age-related changes in MS components, inflammatory markers, and oxidative stress. However, each of these factors has an age-specific, different impact on arterial stiffness. In particular, oxidative stress may be independently associated with arterial stiffness in individuals older than 45 y.

    Elevated blood ammonia leads to hyperammonaemia that affects vital central nervous system (CNS) functions. Fisetin, a naturally occurring flavonoid, exhibits therapeutic benefits, such as anti-cancer, anti-diabetic, anti-oxidant, anti-angiogenic, neuroprotective and neurotrophic effects. In this study, the chronotherapeutic effect of fisetin on ammonium chloride (AC)-induced hyperammonaemic rats was investigated, to ascertain the time point at which the maximum drug effect is achieved. The anti-hyperammonaemic potential of fisetin (50mg/kg b.w. oral) was analysed when administered to AC treated (100mg/kg b.w. i.p.) rats at 06:00, 12:00, 18:00 and 00:00h. Amelioration of pathophysiological conditions by fisetin at different time points was measured by analysing the levels of expression of liver urea cycle enzymes (carbamoyl phosphate synthetase-I (CPS-I), ornithine transcarbamoylase (OTC) and argininosuccinate synthetase (ASS)), nuclear transcription factor kappaB (NF-κB p65), brain glutamine synthetase (GS) and inducible nitric oxide synthase (iNOS) by Western blot analysis. Fisetin increased the expression of CPS-I, OTC, ASS and GS and decreased iNOS and NF-κB p65 in hyperammonaemic rats. Fisetin administration at 00:00h showed more significant effects on the expression of liver and brain markers, compared with other time points. Fisetin could exhibit anti-hyperammonaemic effect owing to its anti-oxidant and cytoprotective influences. The temporal variation in the effect of fisetin could be due to the (i) chronopharmacological, chronopharmacokinetic properties of fisetin and (ii) modulations in the endogenous circadian rhythms of urea cycle enzymes, brain markers, redox enzymes and renal clearance during hyperammonaemia by fisetin. However, future studies in these lines are necessitated. Copyright © 2014 Institute of Pharmacology, Polish Academy of Sciences. Published by Elsevier Urban & Partner Sp. z o.o. All rights reserved.

    Full Text Available Abstract Background Polycystic ovary syndrome (PCOS is an endocrine disease closely related to several risk factors for cardiovascular disease. An abnormal heart rate recovery (HRR, an easily-obtained measure derived from exercise stress test and closely related to an increased risk for cardiovascular mortality, has been recently described in PCOS women. A subclinical increase of the inflammation markers has been also observed in the PCOS. This study was designed to study the relationships between HRR and inflammatory markers in PCOS women. Methods Two-hundred forty-three young PCOS patients without known risk factors for cardiovascular risk were enrolled. All patients underwent hormonal and metabolic profile, white blood cells (WBCs count and C-reactive protein (CRP. HRR was calculated as the difference between heart rate at peak exercise and heart rate at first minute of the cool-down period. Abnormal HRR was defined as ≤18 beats/min for standard exercise testing. Results Eighty-nine out of 243 patients presented abnormal HRR. Serum CRP (1.8 ± 0.7 vs. 1.1 ± 0.4 mg/dl, p 9 cells/l, p versus normal HRR. HRR was significantly associated with both CRP (r = -0.33, p p Conclusion Abnormal HRR and inflammatory markers are closely associated in PCOS women acting probably in concert to increase the cardiovascular risk profile of these patients.

    The genus Oenothera has an outstanding scientific tradition. It has been a model for studying aspects of chromosome evolution and speciation, including the impact of plastid nuclear co-evolution. A large collection of strains analyzed during a century of experimental work and unique genetic possibilities allow the exchange of genetically definable plastids, individual or multiple chromosomes, and/or entire haploid genomes (Renner complexes) between species. However, molecular genetic approaches for the genus are largely lacking. In this study, we describe the development of efficient PCR-based marker systems for both the nuclear genome and the plastome. They allow distinguishing individual chromosomes, Renner complexes, plastomes, and subplastomes. We demonstrate their application by monitoring interspecific exchanges of genomes, chromosome pairs, and/or plastids during crossing programs, e.g., to produce plastome-genome incompatible hybrids. Using an appropriate partial permanent translocation heterozygous hybrid, linkage group 7 of the molecular map could be assigned to chromosome 9.8 of the classical Oenothera map. Finally, we provide the first direct molecular evidence that homologous recombination and free segregation of chromosomes in permanent translocation heterozygous strains is suppressed.

    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

    Inflammatory biomarkers are increased in patients with human immunodeficiency virus (HIV) infection. Antiretroviral treatment (ART) improves some parameters but do not normalize them. The aim of this study is to determine those factors (including microbial translocation) associated with higher inflammation in HIV treated patients. Transversal observational study. HIV patients receiving ART with an HIV viral load (VL)<400 copies/mL. Selection of patients: consecutively between November 2011 and January 2012. Main variable: plasma levels of interleukin 6 (IL-6) and tumour necrosis factor α (TNF-α). Main explanatory variable: microbial translocation markers (16S ribosomal DNA and sCD14). Patients with IL-6 or TNF-α levels above percentile 75 (group 1) were compared with the rest of patients (group 2). Odds ratio (OR) were determined. Eighty-one patients were included (73% male, median age 45 years, 48% stage C). Twenty-six percent had chronic hepatitis C. Median CD4 cell was 493/mm(3) and 30% had detectable HIV VL. 16S ribosomal DNA was detected in 21% of patients. Factors associated with the higher levels of inflammatory markers were 16S ribosomal DNA (OR 77, P<.0001), sCD14 levels (P<.0001) and history of cardiovascular disease (OR 15, P<.01). In multivariate analysis, associations remained for 16S ribosomal DNA (OR 62, P<.0001) and previous cardiovascular disease (OR 25, P<.01). In patients with HIV infection receiving treatment, the higher levels of inflammatory markers are associated with microbial translocation and past cardiovascular events.

    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.

    Previous studies have shown increased inflammatory activity in patients with polycystic ovary syndrome (PCOS); however, it remains uncertain whether this increased inflammatory activity is a consequence of the disorder itself or of the accompanying obesity. We therefore aimed to test the inflammatory marker levels in obese and lean patients with PCOS by using two separate control groups with matching body mass index (BMI). A total of 120 women in reproductive age with (n = 62) and without (n = 60) PCOS were recruited for the study. Patients with PCOS were divided into two groups as obese (n = 32) and lean (n = 30) PCOS groups according to BMI. Two BMI-matched control groups were created. Furthermore, high sensitive CRP protein (hsCRP), neutrophils, lymphocytes, white blood cell count (WBC) and neutrophil to lymphocyte ratio (NLR) were evaluated with complete blood count. The hsCRP (5.5 ± 0.8 vs. 3.1 ± 0.7, p PCOS compared to the control group while lymphocyte count was lower (1.71 ± 0.65 vs. 1.98 ± 0.39, p = 0.008). Similarly, both obese and lean patients with PCOS had higher levels of hsCRP, neutrophils, leukocytes and NLR ratios compared to BMI-matched controls. The correlation analysis revealed a moderate correlation between NLR and hsCRP (r 0.459, p lean and obese patients with PCOS have increased inflammatory markers compared to BMI-matched control groups indicating that the inflammation seen in PCOS might be related with the presence of the disorder rather than with obesity.

    Full Text Available BACKGROUND: There is a prevalence increase of overweight and obesity in Indonesia. Central obesity can lead a variety of chronic diseases through the inflammatory process. There are some markers for low-grade chronic inflammatory, such as cathepsin S, high sensitivity C-reactive protein (hs-CRP, interleukin-1- beta (IL-1β. To our current interest that central obesity can lead to various chronic diseases through the inflammatory process, we conducted a study to investigate correlation of Cathepsin S, hs-CRP, IL-1β in men with central obesity. METHODS: A cross-sectional study was conducted. Seventy-eight selected subjects were examined to collect anthropometric data and prepared for sample collection. Collected samples were processed for the following biochemical analyses: fasting glucose, high density lipoprotein (HDL-cholesterol, triglyceride, serum glutamic oxaloacetic transaminase (SGOT, serum glutamate pyruvate transaminase (SGPT, cathepsin S, hs-CRP, and IL-1β. Data distribution and variable correlation were then statistically analyzed. RESULTS: There were significant correlations between waist circumference (WC and cathepsin S (p=0.030; r=0.214, hs-CRP and cathepsin S (p=0.007; r=0.276, triglyceride and IL-1β (p=0.019; r=-0.235, WC and systolic blood pressure (SBP (p=0.003; r=-0.312, WC and fasting glucose (p=0.000; r=0.380, WC and body mass index (BMI (p=0.000; r=0.708. CONCLUSIONS: Our study showed that cathepsin S was correlated with central obesity, suggesting that cathepsin S could be a potential inflammatory marker in central obesity in the future. KEYWORDS: obesity, inflammation, hs-CRP, cathepsin S, IL-1β, waist circumference.

    Evidence of oxidative stress was reported in individuals with Down syndrome. There is a growing interest in the contribution of the immune system in Down syndrome. The aim of this study is to evaluate the coenzyme Q10 and selected pro-inflammatory markers such as interleukin 6 and tumor necrosis factor α in children with Down syndrome. Eighty-six children (5-8 years of age) were enrolled in this case-control study from two public institutions. At the time of sampling, the patients and controls suffered from no acute or chronic illnesses and received no therapies or supplements. The levels of interleukin 6, tumor necrosis factor α, coenzyme Q10, fasting blood glucose, and intelligence quotient were measured. Forty-three young Down syndrome children and forty-three controls were included over a period of eight months (January-August 2014). Compared with the control group, the Down syndrome patients showed significant increase in interleukin 6 and tumor necrosis factor α (p=0.002), while coenzyme Q10 was significantly decreased (p=0.002). Also, body mass index and fasting blood glucose were significantly increased in patients. There was a significantly positive correlation between coenzyme Q10 and intelligence quotient levels, as well as between interleukin 6 and tumor necrosis factor α. Interleukin 6 and tumor necrosis factor α levels in young children with Down syndrome may be used as biomarkers reflecting the neurodegenerative process in them. Coenzyme Q10 might have a role as a good supplement in young children with Down syndrome to ameliorate the neurological symptoms. Copyright © 2016 Sociedade Brasileira de Pediatria.

    Full Text Available Introduction: Hepcidin is a regulatory protein in iron metabolism; we do not know the role in chronic kidney disease anemia. Methods: 22 patients with CKD anemia and 15 patients with CKD without anemia were investigated. CKD anemia-inclusion criteria: over 18 years, hemoglobin ≤12 g/dl for women and ≤13 g/dl for men, no treatment for anemia 6 months before enrollment, glomerular filtration rate (eGFR <60 ml/min/1.73m2 and stable creatinine three months before enrollment. Exclusion criteria: infection, bleeding, malignancy, systemic or liver disease, immunosuppression, renal replacement therapy. CKD without anemia-inclusion criteria: over 18 years, no anemia or treatment for anemia, CKD with stable creatinine values three months before enrollment. Exclusion criteria: medical conditions known to have a role in the development of polycythemia. Hepcidin-25 and ferritin were measured by ELISA method. Erythropoietin (EPO, tumor necrosis factor (TNF-α, interleukin (IL-6 were evaluated using chemiluminescent enzyme immunometric assays. Unpaired T test, Pearson correlation and multiple regression were used for statistical analysis. Results: Hemoglobin values were significantly lower in anemia group. There were no differences in terms of eGFR, age, body mass index, serum hepcidin, erythropoietin, fibrinogen, IL-6, and TNF-α between CKD patients with and without anemia. Serum hepcidin correlated positively with ferritin (r=0.45 p<0.05, TNF-α (r=0.54, p<0.05 and negatively with erythropoietin (r=-0.51, p<0.05. Multiple linear regression analysis demonstrated that TNF-α is an independent predictor of serum hepcidin in our patients (p=0.003, R=0.71. Conclusion: We found no differences in serum hepcidin, erythropoietin and inflammatory markers in non-dialysis CKD patients with and without anemia.

    2014-12-01

    Full Text Available The aim of this work was to evaluate the potential of moderate consumption of red wine to modulate the intestinal inflammation response on healthy humans. Fecal samples from a human intervention study (n=34 were collected before and after consumption of red wine for 4 weeks, and 24 immune markers including immunoglobulins, cytokines, chemokines and growth factors, were analysed. When considering the whole group of case volunteers, almost no statistically significant differences were found in the immune markers after wine consumption. However, a detailed exploration of the values differentiated a 6-volunteer subgroup that showed unusually high values of cytokines before wine consumption. For this subgroup, wine consumption significantly reduced the content of 16 out of 24 markers down to usual values, especially noticeable for cytokines related to the promotion of initial inflammation (tumor necrosis factor-alpha, interleukin 6 and interferon-gamma. This study reveals, for the first time, changes in the fecal profile of inflammatory markers after moderate consumption of red wine.

    Studies comparing the systemic inflammatory profiles of smokers with and without COPD present discordant findings. To compare the systemic inflammatory profile of smokers with and without COPD. This is a cross-sectional comparative study. Two groups of active smokers of more than 10 pack-years were included: 56 consecutives stable COPD (postbronchodilator FEV 1 /FVCnon-COPD (postbronchodilator FEV 1 /FVC≥0.70). Smoking and clinical, anthropometric and spirometric data were noted. The following blood biomarkers were identified: leukocytes, hemoglobin, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR). According to the levels (normal/abnormal) of these markers, two groups of smokers were formed. Quantitative and qualitative data were expressed, respectively, as means±SD and percentages. Compared to the non-COPD group, the COPD group was older (56±12 vs. 65±8 years) and had a higher smoking consumption (30±18 vs. 52±31 pack-years). Compared to the non-COPD group, the COPD group had higher values of CRP (2.06±1.24 vs. 11.32±11.03mg/L), of ESR (9.59±8.29 vs. 15.96±11.56), of IL-6 (9.28±4.69 vs. 20.27±5.31ng/L) and of TNF-α (18.38±7.98ng/L vs. 8.62±3.72ng/L). Compared to the non-COPD group, the COPD group included higher percentages of smokers with elevated CRP (0 % vs. 32 %), with leukocytosis (6 % vs. 16 %), with higher levels of IL-6 (81 % vs. 98 %) or TNF-α (91 % vs. 100 %). Smokers with COPD, compared to smokers free from COPD, have a marked systemic inflammation. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Type 2 diabetes (T2DM) is a risk factor for Alzheimer's disease and mild cognitive impairment. The etiology of cognitive impairment in people with T2DM is uncertain but, chronic hyperglycemia, cerebral micro vascular disease, severe hypoglycemia, and increased prevalence of macro vascular disease are implicated. to determine the serum levels of soluble vascular adhesion molecule (sVCAM-1) and highly sensitive C-reactive protein (hs-CRP) in elderly type 2 diabetics with mild cognitive impairment (MCI). Our study was conducted on 90 elderly subjects (aged 60 years old or more). They were divided into Group І, 30 patients with T2DM and mild cognitive impairment, group ІІ, 30 patients with T2DM without cognitive impairment and group III, 30 healthy subjects as a control group. They were subjected to history taking, full clinical examination, anthropometric measurement, the Addenbrooke's Cognitive Examination III (ACE---III 2012), Fasting plasma glucose, 2 hours plasma glucose, HbA1c, lipid profile, protein/creatinine ratio, serum sVCAM-1 and hs-CRP. Serum levels of sVCAM-1 in diabetic elderly patients with MCI were significantly higher (946.7 ± 162.01 ng/ml) than diabetic elderly patients without cognitive impairment (479.06 ± 65.27 ng/ml) and control (263.7 ± 72.05 ng/ml) with (P=0.002). Serum levels of Hs-CRP in diabetic elderly patients with MCI were significantly higher than as diabetic elderly patients without cognitive impairment and control with (P=0.005). Elderly diabetic patients with mild cognitive impairment, have higher levels of soluble adhesion molecules and markers of low-grade systemic inflammation than other groups.

    Pain is a common symptom in patients with cancer, including those with head and neck cancer (HNC). While studies suggest an association between chronic inflammation and pain, levels of inflammatory cytokines, such as C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-α), have not been correlated with pain in HNC patients who are not currently undergoing anticancer treatment. The purpose of this study was to examine the relationship between these inflammatory markers and perceived pain in HNC patients prior to anticancer therapy. The study group consisted of 127 HNC patients and 9 healthy controls. Pain was assessed using the Brief Pain Inventory (BPI), and serum levels of CRP and TNF-α were determined using the particle-enhanced turbidimetric immunoassay (PETIA) and ELISA techniques, respectively. Patients experiencing pain had significantly higher levels of CRP (P<0.01) and TNF-α (P<0.05) compared with controls and with patients reporting no pain. There were significantly positive associations between pain, CRP level, and tumor stage. This is the first study to report a positive association between perceived pain and CRP in HNC patients at the time of diagnosis. The current findings suggest important associations between pain and inflammatory processes in HNC patients, with potential implications for future treatment strategies

    Full Text Available Abstract Background Hormonal and enzymatic factors may render certain individuals more susceptible to orthodontically induced inflammatory root resorption (OIIRR. The objectives of this study are (1 to identify biochemical key markers in blood and saliva that may be correlated to the trend of extensive OIIRR and (2 to utilise these markers to predict a susceptible patient-receiving orthodontic treatment. Methods Nine patients (mean age 23 + 2.9 years who had moderate to severe OIIRR that assessed via orthopantomograms and met the inclusion criteria were classified as the root resorption group (RRG. Blood chemistry was evaluated using the collection of fasting blood and unstimulated saliva samples. Multiplex enzyme-linked immunosorbent assay (ELISA arrays were used to screen blood and saliva samples for human cytokines, chemokines and several key enzymes that may play a role in root resorption following orthodontic force application. Biochemical findings from 16 matching subjects were used as the control (CG for comparative measurements. Results Patients with moderate to severe OIIRR showed a significant increase in salivary cytokines including interleukin (IL 7, IL-10, IL-12p70 and interferon-gamma (IFN-γ level as well as a significant decrease in IL-4 level. Osteocalcin and procollagen type I N-terminal peptide (P1NP appeared to be the only blood factors that showed a significant difference, more in the CG than the RRG. Conclusions Saliva might be a more valuable way of measuring changes in cytokine expression than blood secondary to orthodontic treatment. Although the increased expression of pro-inflammatory and anti-inflammatory cytokines may be determinants in the development of moderate to severe OIIRR, cytokine expression may be affected by several potential inflammations in another part of the body. Future research could investigate the cause/effect relationship of different cytokines, in a larger group of patients and at different

    Full Text Available Vitamin D deficiency is very prevalent among the patients with end-stage renal disease. The etiology of this is multifactorial, including nutritional deficiency, insufficient expo- sure to sunlight, race, obesity and not the least, impaired Vitamin D synthesis and metabolism in chronic kidney disease patients. We hypothesized that lower Vitamin D level will be associated with higher inflammatory burden and low immunological response to hepatitis B vaccination in hemodialysis (HD population. The study was carried out in March 2013 among 100 HD patients who were identified to be eligible for the study. This was a cross-sectional study analyzing the relationship between Vitamin D level and inflammatory markers in HD patients. A relationship between Vitamin D level and markers of mineral bone disorder was also analyzed. We also analyzed the relationship between Vitamin D level and hemoglobin and erythropoietin dosage. Hemoglobin, transferrin saturation, and erythropoietin dose were used to study the relationship between Vitamin D and markers of anemia. Antibodies to hepatitis B surface antigen were measured to study the response between Vitamin D level and immune response to hepatitis B vaccine. Vitamin D levels were significantly lower in females compared to males (P = 0.009 and diabetics compared to non-diabetics (P = 0.02. No significant association was observed between Vitamin D levels with immune response to hepatitis B vaccine (P = 0.89, C-reactive protein (P = 0.19, serum albumin (P = 0.17, hemoglobin level (P = 0.18, and erythropoietin requirement (P = 0.87, parathyroid hormone (PTH levels (P = 0.57, calcium levels (P = 0.79 and phosphate level (P = 0.1.

    Full Text Available Background: Muscle wasting is a common complication of Chronic Kidney Disease (CKD and is clinically important given its strong association with morbidity and mortality in many other chronic conditions. Exercise provides physiological benefits for CKD patients, however the molecular response to exercise remains to be fully determined. We investigated the inflammatory and molecular response to resistance exercise before and after training in these patients.Methods: This is a secondary analysis of a randomized trial that investigated the effect of 8 week progressive resistance training on muscle mass and strength compared to non-exercising controls. A sub-set of the cohort consented to vastus lateralis skeletal muscle biopsies (n = 10 exercise, n = 7 control in which the inflammatory response (IL-6, IL-15, MCP-1 TNF-α, myogenic (MyoD, myogenin, myostatin, anabolic (P-Akt, P-eEf2 and catabolic events (MuRF-1, MAFbx, 14 kDa, ubiquitin conjugates and overall levels of oxidative stress have been studied.Results: A large inflammatory response to unaccustomed exercise was seen with IL-6, MCP-1, and TNF-α all significantly elevated from baseline by 53-fold (P < 0.001, 25-fold (P < 0.001, and 4-fold (P < 0.001, respectively. This response was reduced following training with IL-6, MCP-1, and TNF-α elevated non-significantly by 2-fold (P = 0.46, 2.4-fold (P = 0.19, and 2.5-fold (P = 0.06, respectively. In the untrained condition, an acute bout of resistance exercise did not result in increased phosphorylation of Akt (P = 0.84, but this was restored following training (P = 0.01. Neither unaccustomed nor accustomed exercise resulted in a change in myogenin or MyoD mRNA expression (P = 0.88, P = 0.90, respectively. There was no evidence that resistance exercise training created a prolonged oxidative stress response within the muscle, or increased catabolism.Conclusions: Unaccustomed exercise creates a large inflammatory response within the muscle, which is

    Prenatal depression (PND) is a common psychiatric disorder in pregnant women and leads to psychosocial dysfunction, high suicidal rate, and adverse childcare. Patients with PND have omega-3 polyunsaturated fatty acid (omega-3 or n-3 PUFAs) deficits, which might link to chronic low-grade inflammatory process and the pathophysiological mechanisms of depression. In this case-control study, we examined the levels of PUFAs and inflammatory cytokines in PND. Blood samples were obtained and analyzed from 16 healthy controls and 17 depressed cases (PND group) diagnosed with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Independent sample t-test and correlation analysis were performed with Statistical Package for the Social Sciences (SPSS) logistics correlation analysis. PND group had significantly lower levels of total n-3 (p=0.026), docosahexaenoic acid (DHA) (p=0.020) and eicosapentaenoic (EPA) (p=0.019) but a higher omega-6 (n-6)/n-3 PUFAs ratio (p=0.007) and tumor necrosis factor alpha (TNF-α) (p=0.016) level. Moreover, the duration of current PND episodes were also significantly correlated with DHA, EPA, n-3 PUFAs, n-6/n-3 ratio and TNF-α. In terms of PUFAs and cytokine levels, only DHA was inversely correlated with TNF-α. PND is significantly associated with lower DHA, EPA, and total n-3 PUFAs levels and an increased n-6/n-3 PUFAs ratio, while the duration of PND is associated with lower levels of n-3 PUFAs, including DHA and EPA. The correlation of PUFAs levels with depression and TNF-α level grant further investigation into the inflammatory process underlying PND, mediated by PUFAs. Copyright © 2017 Elsevier Inc.

    The time for inflammatory markers of former smokers to revert to never smoker levels is still controversial, ranging from 5 to 20 years. We aimed to determine the time from smoking cessation for white blood cell (WBC) count and serum C-reactive protein (CRP) levels to return to those of never-smokers, after adjusting for confounding factors and for secondhand smoke (SHS) exposure among participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Cross-sectional analysis of baseline participants of ELSA-Brasil. We used linear regression analysis and generalized linear models with gamma distribution and logarithmic link function to estimate the association of WBC count and CRP levels with time from smoking cessation. The following confounding factors were considered: sex, age, education, SHS, alcohol consumption, leisure-time physical activity, BMI, total cholesterol/HDL ratio, hypertension, diabetes, cardiovascular disease, and chronic obstructive pulmonary disease (COPD). Results: After all adjustments, time from smoking cessation <10 years remained associated with higher WBC count (eg, time from smoking cessation ≥ 5 and <10 years: β: 167.92; 95%CI: 23.52 312.31), while only time from smoking cessation <1 year remained associated with higher arithmetic mean of CRP (AMR: 1.26, 95%CI: 1.03‒1.54). Levels of inflammatory markers were similar to those of never-smokers 1 year after smoking cessation for CRP and 10 years after for WBC. The results may add to the arsenal health professionals have to encourage their patients to quit smoking, as some harms from smoking appear to revert to never-smokers' level sooner than previously reported. Longitudinal studies should confirm our findings. © The Author 2017. Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco. All rights reserved.

    To examine the associations of body fatness, metabolic and inflammatory markers with retinal vessel calibers among children. We performed a population-based cohort study among 4145 school-age children. At the median age of 6.0 years (95% range 5.8, 8.0 years), we measured body mass index, total and abdominal fat mass, metabolic and inflammatory markers (blood levels of lipids, insulin and C-peptide and C-reactive protein) and retinal vascular calibers from retinal photographs. We observed that compared with normal weight children, obese children had narrower retinal arteriolar caliber (difference -0.21 s.d. score (SDS; 95% confidence interval (CI) -0.35, -0.06)), but not venular caliber. Continuous analyses showed that higher body mass index and total body fat mass, but not android/gynoid fat mass ratio and pre-peritoneal fat mass, were associated with narrower retinal arteriolar caliber (Pfat mass), but not with retinal venular caliber. Lipid and insulin levels were not associated with retinal vessel calibers. Higher C-reactive protein was associated with only wider retinal venular caliber (difference 0.10 SDS (95% CI 0.06, 0.14) per SDS increase in C-reactive protein). This latter association was not influenced by body mass index. Higher body fatness is associated with narrower retinal arteriolar caliber, whereas increased C-reactive protein levels are associated with wider retinal venular caliber. Increased fat mass and inflammation correlate with microvascular development from school-age onwards.

    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.

After incubation, the PBMC were stained with fluorochrome-labeled monoclonal antibodies for CD3, CD56, and CD69 to monitor cellular activation by flow cytometry. The culture supernatants were tested for cytokine profile using a 27-plex Luminex array, including pro- and anti-inflammatory cytokines, chemokines, and growth factors.Results: Inactivated B. coagulans GBI-30, 6086 cells induced the CD69 early activation marker on CD3+ CD56− T lymphocytes, CD3+ CD56+ NKT cells, CD3−CD56+ NK cells, and also some cells within the CD3−CD56− non-T non-NK cell subset. Culture supernatants showed robust increases in the immune-activating cytokines IL-1β, IL-6, IL-17A, and TNF-α. IFN-γ levels were increased, along with three chemokines, MCP-1, MIP-1α, and MIP-1β. The two anti-inflammatory cytokines IL-1ra and IL-10 showed increases, as well as the G-CSF growth factor involved in repair and stem cell biology. In contrast, GM-CSF levels showed a mild decrease, showing a highly selective growth factor response.Conclusion: The inactivated B. coagulans GBI-30, 6086 cells activated human immune cells and altered the production of both immune activating and anti-inflammatory cytokines and chemokines. Of special importance is the novel demonstration of a selective upregulation of the G-CSF growth factor involved in postinjury and postinflammation repair and regeneration. This suggests that

    Gastrointestinal illnesses are a significant health burden for the US population, with 40 million office visits each year for gastrointestinal complaints and nearly 250,000 deaths. Acute and chronic inflammations are a common element of many gastrointestinal diseases. Inflammatory processes may be initiated by a chemical injury (acid reflux in the esophagus), an infectious agent (Helicobacter pylori infection in the stomach), autoimmune processes (graft versus host disease after bone marrow transplantation), or idiopathic (as in the case of inflammatory bowel diseases). Inflammation in these settings can contribute to acute complaints (pain, bleeding, obstruction, and diarrhea) as well as chronic sequelae including strictures and cancer. Research into the pathophysiology of these conditions has been limited by the availability of primary human tissues or appropriate animal models that attempt to physiologically model the human disease. With the many recent advances in tissue engineering and primary human cell culture systems, it is conceivable that these approaches can be adapted to develop novel human ex vivo systems that incorporate many human cell types to recapitulate in vivo growth and differentiation in inflammatory microphysiological environments. Such an advance in technology would improve our understanding of human disease progression and enhance our ability to test for disease prevention strategies and novel therapeutics. We will review current models for the inflammatory and immunological aspects of Barrett's esophagus, acute graft versus host disease, and inflammatory bowel disease and explore recent advances in culture methodologies that make these novel microphysiological research systems possible. © 2014 by the Society for Experimental Biology and Medicine.

    Canned sardines are a ready-to-use fish product with excellent nutritional properties owing to its high n-3 long-chain PUFA content, mainly EPA (20 : 5n-3) and DHA (22 : 6n-3). The present study aimed to assess the effect of two dosages of canned sardines, recommended for the primary and secondary prevention of human CVD, on the inflammatory marker concentrations and fatty acid composition of erythrocytes and key metabolic tissues (liver, muscle, adipose tissue and brain) in the rat model. Wistar rats were fed a diet containing 11 % (w/w) of canned sardines (low-sardine (LS) diet) and a diet containing 22 % (w/w) of canned sardines (high-sardine (HS) diet) for 10 weeks. Daily food intake, weight gain, and organ and final body weights were not affected by the dietary treatments. The concentrations of total cholesterol, HDL-cholesterol and LDL-cholesterol decreased in both the LS and HS groups, while those of alanine aminotransferase and adiponectin increased. The concentrations of IL-1β increased only with the highest dosage of sardine. The dose-dependent influence of the graded levels of EPA+DHA was tissue specific. Compared with that of other tissues and erythrocytes, the fatty acid composition of the brain was less affected by the canned sardine-supplemented diets. In contrast, the retroperitoneal adipose tissue was highly responsive. The deposition ratios of EPA and DHA indicated that the LS diet was optimal for DHA deposition across the tissues, except in the retroperitoneal adipose tissue. Taken together, our findings indicate that a LS diet positively affects plasma lipid profiles and inflammatory mediators, whereas a HS diet has contradictory effects on IL-1β, which, in turn, is not associated with variations in the concentrations of other pro-inflammatory cytokines. This finding requires further investigation and pathophysiological understanding.

    The ligand [{sup 11}C]PK11195 binds with high affinity and selectivity to peripheral benzodiazepine receptor, expressed in high amounts in macrophages. In humans, [{sup 11}C]PK11195 has been used successfully for the in vivo imaging of inflammatory processes of brain tissue. The purpose of this study was to explore the feasibility of [{sup 11}C]PK11195 in imaging inflammation in the atherosclerotic plaques. The presence of PK11195 binding sites in the atherosclerotic plaques was verified by examining the in vitro binding of [{sup 3}H]PK11195 onto mouse aortic sections. Uptake of intravenously administered [{sup 11}C]PK11195 was studied ex vivo in excised tissue samples and aortic sections of a LDLR/ApoB48 atherosclerotic mice. Accumulation of the tracer was compared between the atherosclerotic plaques and non-atherosclerotic arterial sites by autoradiography and histological analyses. The [{sup 3}H]PK11195 was found to bind to both the atherosclerotic plaques and the healthy wall. The autoradiography analysis revealed that the uptake of [{sup 11}C]PK11195 to inflamed regions in plaques was more prominent (p = 0.011) than to non-inflamed plaque regions, but overall it was not higher than the uptake to the healthy vessel wall. Also, the accumulation of {sup 11}C radioactivity into the aorta of the atherosclerotic mice was not increased compared to the healthy control mice. Our results indicate that the uptake of [{sup 11}C]PK11195 is higher in inflamed atherosclerotic plaques containing a large number of inflammatory cells than in the non-inflamed plaques. However, the tracer uptake to other structures of the artery wall was also prominent and may limit the use of [{sup 11}C]PK11195 in clinical imaging of atherosclerotic plaques. (orig.)

    Polycystic ovary syndrome (PCOS) is an endocrine disease closely related to several risk factors for cardiovascular disease. An abnormal heart rate recovery (HRR), an easily-obtained measure derived from exercise stress test and closely related to an increased risk for cardiovascular mortality, has been recently described in PCOS women. A subclinical increase of the inflammation markers has been also observed in the PCOS. This study was designed to study the relationships between HRR and inflammatory markers in PCOS women. Two-hundred forty-three young PCOS patients without known risk factors for cardiovascular risk were enrolled. All patients underwent hormonal and metabolic profile, white blood cells (WBCs) count and C-reactive protein (CRP). HRR was calculated as the difference between heart rate at peak exercise and heart rate at first minute of the cool-down period. Abnormal HRR was defined as PCOS patients with abnormal versus normal HRR. HRR was significantly associated with both CRP (r = -0.33, p PCOS women acting probably in concert to increase the cardiovascular risk profile of these patients.

    Objective: Preterm premature rupture of membranes (PPROM) is closely related with maternal and fetal complications. Therefore, early diagnosis is extremely important to provide maternal and fetal well-being. Many inflammatory markers have been evaluated for their ability to diagnose membrane rupture at early stages. We aimed to investigate the relationship between the platelet-to-lymphocyte ratio (PLR) and preterm premature membrane rupture. Material and Methods: In this study, 121 pregnant women with PPROM and 96 age-matched pregnant women with spontaneous preterm labor who were admitted to our hospital between January 2014 and December 2015 were enrolled. Demographic data, complete blood cell count results, and neonatal outcomes were recorded. Results: The neutrophil and platelet counts were higher in the PPROM group (9948.4±3393.2 vs. 7466.1±1698.5/mm3 and 244.5±60 vs. 210.6±64.8/mm3, respectively, ppremature rupture of membranes was evaluated using an ROC curve. The sensitivity and specificity of the PLR was 57.8% and 73.7%, respectively, at a threshold >117.14 (p<0.001). Conclusion: The PLR might be a cost effective, easy to use, and practical marker for the early diagnosis of PPROM, which can help to determine the appropriate waiting time for delivery and provide maternal and fetal well-being.

    The aim of our study is to analyse the inflammatory markers and lipid accumulation product (LAP) index in nonobese adolescents and younger aged women with polycystic ovary syndrome (PCOS) compared with age and body mass index (BMI)-matched healthy controls and to determine whether the investigated parameters are potential markers for the etiopathogenesis of PCOS. We also aim to determine whether these inflammatory markers are predictive for developing some clinical implications, such as cardiovascular disease (CVD) and insulin resistance (IR), associated with PCOS. A total of 34 adolescents and younger aged females with PCOS, and 33 age and BMI-matched healthy controls were recruited for our study. All participants were nonobese (BMIpredictive effect of investigated inflammatory markers and LAP index on CVD risk among PCOS patients after adjustment for abdominal obesity. We also found a positive predictive effect of WBC and a negative predictive effect of lymphocytes on IR in PCOS patients after adjustment for abdominal obesity. We did not find any predictor effect of NEO on IR, but it was a positive predictive marker for an elevated HOMA-IR index. Elevated NEO, CRP levels and LAP index could have potential roles in the etiopathogenesis of PCOS in nonobese adolescents and younger aged females,NEO could be a predictive marker for elevated HOMA-IR index, and WBC and lymphocytes could be predictive for the development of IR among nonobese adolescents and younger aged females with PCOS.

    Background Studies have reported associations between long-term air pollution exposures and cardiovascular mortality. The biological mechanisms connecting them remain uncertain. Methods We examined associations of fine particles (PM2.5) and ozone with serum markers of cardiovascular disease risk in a cohort of midlife women. We obtained information from women enrolled at six sites in the multi-ethnic, longitudinal Study of Women's Health Across the Nation, including repeated measurements of high-sensitivity C-reactive protein (hs-CRP), fibrinogen, tissue-type plasminogen activator antigen (tPA-ag), plasminogen activator inhibitor Type 1 (PAI-1), and Factor VIIc (Factor VII coagulant activity). We obtained residence-proximate PM2.5 and ozone monitoring data for a maximum five annual visits, calculating prior year, six-month, one-month, and one-day exposures and their relations to serum markers using longitudinal mixed models. Results For the 2,086 women studied from 1999 through 2004, PM2.5 exposures were associated with all blood markers except Factor VIIc after adjusting for age, race/ethnicity, education, site, body mass index, smoking, and recent alcohol use. Adjusted associations were of the strongest for prior year exposures for hs-CRP (21% increase per 10 μg/m3 PM2.5, 95% CI: 6.6, 37), tPA-ag (8.6%, 95% CI: 1.8, 16), and PAI-1 (35%, 95% CI: 19, 53). An association was also observed between year prior ozone exposure and Factor VIIc (5.7% increase per 10 ppb ozone, 95% CI: 2.9, 8.5). Conclusions Our findings suggest that prior year exposures to PM2.5 and ozone are associated with adverse effects on inflammatory and hemostatic pathways for cardiovascular outcomes in midlife women.

    Antioxidants have been reported to have anti-inflammatory effects, but there is a lack of research comparing food to supplement antioxidant sources. The aim of this study was to determine if increases in intake of foods naturally rich in antioxidants would lower blood levels of inflammatory markers more than consuming antioxidant supplements among adults with cardiovascular disease risk factors. Eighty-eight generally healthy adults with ≥1 elevated risk factor for cardiovascular disease were randomized in a single-blind (diets)/double-blind (supplements), parallel-group study for 8 weeks. Participants consumed (1) usual diet and placebo pills (n = 29), (2) usual diet and antioxidant supplements (n = 29), or (3) antioxidant-rich foods closely matched to antioxidant content of supplements and placebo (n = 30). Usual diet combined with antioxidant supplements or increased antioxidant-rich food intake was designed to approximately double daily habitual antioxidant intake. Antioxidant pills included carotenoids, mixed tocopherols, vitamin C, and selenium. Fasting blood samples were analyzed for inflammatory marker concentrations of interleukin-6, monocyte chemotactic protein-1, and soluble intercellular adhesion molecule-1. Participants in the intervention groups successfully doubled most antioxidants as verified by diet records and elevated blood concentrations in treatment groups. Baseline levels of inflammatory markers for the entire study group were 110 ± 65 pg/mL for monocyte chemotactic protein-1, 0.9 ± 0.7 pg/mL for interleukin-6, and 217 ± 56 ng/mL for soluble intercellular adhesion molecule-1 (means ± standard deviation) and did not differ by treatment arm. After 8 weeks, there were no significant within-group changes or between-group 8-week change differences in inflammatory marker concentrations. In conclusion, no beneficial effects were detected on the inflammatory markers investigated in response to antioxidants from foods or supplements. Copyright

    There is a need for an ideal indicator of surgery in patients presenting with acute abdomen. Several markers have been analysed, but the search still continues as none have proven effective. This study aimed to analyse and compare the predictive value of plasma procalcitonin (PCT) strip test in patients presenting with acute abdomen and identify a useful cut-off value to differentiate patients that would benefit with surgery from those that require conservative management. A prospective study was conducted in the department of general surgery from June 2012 to June 2013. Plasma PCT was estimated by the semi-quantitative strip test. The levels of plasma PCT and other routinely used markers of inflammation were analysed and compared. Of the total of 58 patients, 44 patients (76%) were men with a mean age of 45 years. Forty patients required emergency surgical intervention. A plasma PCT value of >0.5 ng/mL at admission was 80% sensitive and 100% specific for predicting need for antibiotics in patients with acute abdomen that were managed conservatively. The mean plasma PCT value in the patients undergoing surgery (5.0-10.0 ng/mL) was significantly more than in those managed conservatively (0.5-2.0 ng/mL). Using receiver operating characteristic (ROC) curves a cut-off for plasma PCT of >5.0 ng/mL was 75% sensitive and 100% specific for considering surgical intervention in patients presenting with acute abdomen. Plasma PCT (value >5 ng/mL) could be used as an adjunct to clinical examination to predict requirement of surgery in patients presenting with acute abdomen. © 2015 Royal Australasian College of Surgeons.

Arterial stiffness (AS can be determined by measurement of arterial pulse wave velocity (APWV. Separate from any role as a surrogate marker, AS is an important determinant of pulse pressure, left ventricular function and coronary artery perfusion pressure. Proximal elastic arteries and peripheral muscular arteries respond differently to aging and to medication. Endogenous human growth hormone (hGH, secreted by the anterior pituitary, peaks during early adulthood, declining at 14% per decade. Levels of insulin-like growth factor-I (IGF-I are at their peak during late adolescence and decline throughout adulthood, mirror imaging GH. Arterial endothelial dysfunction, an accepted cause of increased APWV in GH deficiency (GHD is reversed by recombinant human (rh GH therapy, favorably influencing the risk for atherogenesis. APWV is a noninvasive method for measuring atherosclerotic and hypertensive vascular changes increases with age and atherosclerosis leading to increased systolic blood pressure and increased left ventricular hypertrophy. Aerobic exercise training increases arterial compliance and reduces systolic blood pressure. Whole body arterial compliance is lowered in strength-trained individuals. Homocysteine and C-reactive protein are two infl ammatory markers directly linked with arterial endothelial dysfunction. Reviews of GH in the somatopause have not been favorable and side effects of treatment have marred its use except in classical GHD. Is it possible that we should be assessing the combined effects of therapy with rhGH and rh

    Full Text Available Early predictors for the development of stroke-associated infection may identify patients at high risk and reduce post-stroke infection and mortality.In 383 prospectively enrolled acute stroke patients we assessed time point and type of post-stroke infections (i.e. pneumonia, urinary tract infection (UTI other infection (OI. Blood samples were collected on admission, and days 1, and 3 to assess white blood cells (WBC, monocytes, C-reactive protein (CRP, procalcitonin (PCT, and copeptin. To determine the magnitude of association with the development of infections, odds ratios (OR were calculated for each prognostic blood marker. The discriminatory ability of different predictors was assessed, by calculating area under the receiver operating characteristic curves (AUC. Prognostic models including the three parameters with the best performance were identified.Of 383 patients, 66 (17.2% developed an infection after onset of stroke. WBC, CRP, copeptin and PCT were all independent predictors of any infection, pneumonia and UTI developed at least 24 hours after measurements. The combination of the biomarkers WBC, CRP and copeptin (AUC: 0.92 and WBC, CRP and PCT (AUC: 0.90 showed a better predictive accuracy concerning the development of pneumonia during hospitalization compared to each marker by itself (p-Wald <0.0001.Among ischemic stroke patients, copeptin, PCT, WBC and CRP measured on admission were predictors of infection in general, and specifically for pneumonia and UTI within 5 days after stroke. The combination of these biomarkers improved the prediction of patients who developed an infection.

    Objective The aim of this study was to document the immune activating and anti-inflammatory effects of inactivated probiotic Bacillus coagulans GBI-30, 6086 (Staimune™) cells on human immune cells in vitro. Methods In vitro cultures of human peripheral blood mononuclear cells (PBMC) from healthy blood donors were treated with inactivated B. coagulans GBI-30, 6086 cells for 24 hours. After incubation, the PBMC were stained with fluorochrome-labeled monoclonal antibodies for CD3, CD56, and CD69 to monitor cellular activation by flow cytometry. The culture supernatants were tested for cytokine profile using a 27-plex Luminex array, including pro- and anti-inflammatory cytokines, chemokines, and growth factors. Results Inactivated B. coagulans GBI-30, 6086 cells induced the CD69 early activation marker on CD3+ CD56− T lymphocytes, CD3+ CD56+ NKT cells, CD3−CD56+ NK cells, and also some cells within the CD3−CD56− non-T non-NK cell subset. Culture supernatants showed robust increases in the immune-activating cytokines IL-1β, IL-6, IL-17A, and TNF-α. IFN-γ levels were increased, along with three chemokines, MCP-1, MIP-1α, and MIP-1β. The two anti-inflammatory cytokines IL-1ra and IL-10 showed increases, as well as the G-CSF growth factor involved in repair and stem cell biology. In contrast, GM-CSF levels showed a mild decrease, showing a highly selective growth factor response. Conclusion The inactivated B. coagulans GBI-30, 6086 cells activated human immune cells and altered the production of both immune activating and anti-inflammatory cytokines and chemokines. Of special importance is the novel demonstration of a selective upregulation of the G-CSF growth factor involved in postinjury and postinflammation repair and regeneration. This suggests that important immunogenic cell wall components, such as lipoteichoic acid, are undamaged after the inactivation and retain the complex beneficial biological activities previously demonstrated for the cell walls

    The aim of the study was to analyze cytokine profiles in amniotic fluid (AF) samples of children developing autism spectrum disorders (ASD) and controls, adjusting for maternal autoimmune disorders and maternal infections during pregnancy. AF samples of 331 ASD cases and 698 controls were analyzed for inflammatory cytokines using Luminex xMAP technology utilizing a historic birth cohort. Clinical data were retrieved from nationwide registers, and case-control differences in AF cytokine levels were assessed using chi-square tests, logistic and tobit regression models. Overall, individuals with ASD had significantly elevated AF levels of TNF-α and TNF-β compared to controls. Analyzing individuals diagnosed only with ICD-10 codes yielded significantly elevated levels of IL-4, IL-10, TNF-α and TNF-β in ASD patients. Restricting analysis to infantile autism cases showed significantly elevated levels of IL-4, TNF-α and TNF-β compared to controls with no psychiatric comorbidities. Elevated levels of IL-6 and IL-5 were found in individuals with other childhood psychiatric disorders (OCPD) when compared to controls with no psychiatric comorbidities. AF samples of individuals with ASD or OCPD showed differential cytokine profiles compared to frequency-matched controls. Further studies to examine the specificity of the reported cytokine profiles in ASD and OCPD are required.

    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.

    The aim of this study was to evaluate the effects of laser phototherapy on the degenerative modifications on the articular cartilage after the anterior cruciate ligament transection (ACLT) in the knee of rats. Eighty male rats (Wistar) were distributed into four groups: intact control group (IG), injured control group (CG), injured laser treated group at 10 J/cm2 (L10), and injured laser treated group at 50 J/cm2 (L50). Animals were distributed into two subgroups, sacrificed in 5 and 8 weeks postsurgery. The ACLT was used to induce knee osteoarthritis in rats. After 2 weeks postsurgery, laser phototherapy initiated and it was performed for 15 and 30 sessions. The histological findings revealed that laser irradiation, especially at 10 J/cm2, modulated the progression of the degenerative process, showing a better cartilage structure and lower number of condrocytes compared to the other groups. Laser phototherapy was not able to decrease the degenerative process measured by Mankin score and prevent the increase of cartilage thickness related to the degenerative process. Moreover, it did not have any effect in the biomodulation of the expression of markers IL1β, tumor necrosis factor-α, and metalloprotein-13. Furthermore, laser irradiated animals, at 50 J/cm2 showed a lower amount of collagen type 1.

    Inflammation has been implicated in the pathophysiology of a series of cardiovascular diseases. C-reactive protein (CRP) is a marker of inflammation easily obtained in the emergency room. To study the prognostic value of CRP in patients admitted for acute decompensated heart failure (ADHF). A prospective cohort of 119 patients with ADHF treated in the emergency room. Mean age was 74+/-11 years and 76 (64%) of patients were male. All were New York Heart Association Functional Class III or IV. CRP was measured by nephelometry at admission. Patients were followed after hospital discharge for an average of 12+/-9.7 months and cardiovascular mortality was the outcome analyzed. There were 44 (36.9%) deaths, all from cardiovascular causes. Individuals with CRP > 3 mg/dl had higher mortality than those below this level (p=0.018). In the multivariate analysis using Cox proportional model, CRP proved to be the most important independent prognostic factor (odds ratio 0.0916 [95% CI = 0.0341 - 0.1490] for each one-unit increment in CRP). CRP is an independent cardiovascular mortality predictor in patients with ADHF, indicating that inflammation represents an important component in the pathophysiology of the disease.

    Essential hypertension (EH) is a common disease with a clear genetic component. Inflammation and endothelial dysfunction play a prominent role in the development of persistent blood pressure elevation. The aim of the current study was to detect an association between EH and polymorphic markers in genes encoding for molecules involved in the control of intercellular interactions during the inflammation process. We analysed SNPs in SELE, SELP, SELL, ICAM1, VEGFA, IL1B, IL6, IL10 and IL12B genes in a group of 534 men of Tatar ethnicity (217 patients with EH and 317 controls). Using a Markov chain Monte-Carlo-based approach (APSampler), we found genotype and allelic combinations associated with EH. The most significant associations were observed for SELE rs2076059*C-SELP rs6131*A-VEGFA -2549*I-IL1B rs16944*C (p = 3.42 × 10(-5), FDR q = 0.035) and SELE rs2076059*C-SELP rs6131*A-IL12B rs3212227*C-IL1B rs16944*C (p = 323 × 10(-4), FDR q = 0.035).

    Full Text Available [b]Introduction.[/b] It is well known that exposure to organic dust can cause adverse respiratory effect. The pathogen-associated molecular patterns (PAMPS in the organic dust, such as endotoxin from Gram-negative bacteria cell wall and fungal components, can trigger the release of cytokine (e.g. Interleukin 1β (IL-1β and chemokine (e.g. Interleukin 8 (IL-8 from the immune cells in the airways. [b]Objective.[/b] To evaluate the potential inflammatory effects of organic dust exposure in energy plants in Denmark. [b]Materials and methods[/b]. Nasal lavage (NAL and exhaled breath condensate (EBC were sampled at Monday morning (referred to as before work and again at Thursday afternoon (referred to as after work. NAL IL-8, EBC pH, IL-1β concentration were measured. Personal exposure to endotoxin and dust was calculated from time spent on different tasks and measured average work area exposures. [b]Results.[/b] Before work, workers from biofuel plants had a higher IL-1β and IL-8 concentration compared to conventional fuel plants (control group. Specifically, the IL-1β level of moderately and most exposed group, and IL-8 level of the least exposed group were higher compared to the control group. The changes of IL-1β, pH and IL-8 during a work week were not significant. Workers with rhinitis had a lower percentage change of IL-8 compared to healthy workers. [b]Conclusions[/b]. An increased level of EBC IL-1β in biofuel energy plant workers before work indicated a chronic or sub-chronic inflammation. The percentage change of IL-8 was lower in workers with rhinitis compared to healthy workers.

    Inflammation has been widely recognized as a contributor to cancer progression and several inflammatory markers have been reported as associated with the clinical outcomes in patients with various types of cancer. Recently, a novel inflammatory marker, the systemic inflammatory score (SIS), which is based on a combination of the lymphocyte-to-monocyte ratio (LMR) and the serum albumin concentration has been reported as a useful prognostic marker. The aim of the present study was to assess the prognostic value of the SIS in patients with unresectable metastatic colorectal cancer (mCRC). The retrospective cohort study included 160 patients who underwent combination chemotherapy for unresectable mCRC between January 2008 and December 2016. The SIS was used to classify the patients into three groups based on their LMR and the serum albumin concentration. Patients with high-LMR and high serum albumin level were given a score of 0; patients with low-LMR or low serum albumin level were given a score of 1; patients with low-LMR and low serum albumin level were given a score of 2. There were significant differences in the overall survival among the three SIS groups and the SIS was an independent prognostic factor for the overall survival. Although the SIS was significantly associated with the overall survival rate even when using the original cut-off values, the SIS according to the new cut-off values had a more accurate prognostic value. The present study determined that the SIS was a useful biomarker for predicting the survival outcomes in patients with unresectable mCRC, although the optimum cut-off value of the SIS according to the patients' background needs to be examined in further studies.

    Full Text Available Although oxidative stress and inflammation are important mechanisms in the pathophysiology of preeclampsia and preterm diseases, their contribution to the respiratory prognosis of premature infants of hypertensive mothers is not known. Our objective was to determine the levels of oxidative stress and inflammation markers in the airways of premature infants born to hypertensive and normotensive mothers, in the first 72 h of life, and to investigate whether they are predictors of bronchopulmonary dysplasia (BPD/death. This was a prospective study with premature infants less than 34 weeks’ gestation on respiratory support who were stratified into 2 groups: 32 premature infants of hypertensive mothers and 41 of normotensive women, with a mean gestational age of 29 weeks. Exclusion criteria were as follows: diabetes mellitus, chorioamnionitis, malformation, congenital infection, and death within 24 h after birth. The outcome of interest was BPD/death. Malondialdehyde (MDA, nitric oxide (NO, and interleukin 8 (IL-8 were measured in airway aspirates from the first and third days of life and did not differ between the groups. Univariate and multivariate statistical analyses were performed. The concentrations of MDA, NO, and IL-8 were not predictors of BPD/death. Premature infants who developed BPD/death had higher levels of IL-8 in the first days of life. The gestational age, mechanical ventilation, and a small size for gestational age were risk factors for BPD/death. In conclusion, the biomarkers evaluated were not increased in premature infants of hypertensive mothers and were not predictors of BPD/death.

    Asthma is the most common chronic disease of childhood in industrialised countries. T helper-2 (Th-2) cells, mast cells and eosinophils have a role in inflammation of asthma. Recently it was shown that platelets also play a role in asthma. Mean platelet volume shows platelet size and reflects platelet activation. The aim of this retrospective study is to evaluate levels of mean platelet volume in asthmatic patients during asymptomatic periods and exacerbations compared with healthy controls. The study consisted of 100 asthmatic patients (male/female: 55/45, mean age: 8.2±3.3) and 49 age and sex matched healthy children as a control group. Mean platelet volume values of asthmatic patients during asymptomatic period were 7.7±0.8fL while mean platelet volume values in asthmatics during exacerbation were 7.8±0.9fL. Comparison of mean platelet volume values of asthmatic patients and healthy controls both in acute asthmatic attack and asymptomatic period showed no difference (p>0.05). Comparison of mean platelet volume values at asthmatic attack and asymptomatic period also had no difference (p>0.05). The presence of atopy, infection, eosinophilia, elevated immunoglobulin E, and severity of acute asthmatic attack did not influence mean platelet volume values. The results of our study suggest that mean platelet volume values may not be used as a marker in bronchial asthma, although prospective studies with larger number of patients are needed to evaluate the role of mean platelet volume in asthma.

    Obesity considered being a low-grade inflammatory disease. The objective of this study was to examine the association between inflammatory markers (IM) including C-reactive protein (hs-CRP), Interleukin-6 (IL-6), and homocystein (Hcy) and obesity-related factors (e.g. BMI, waist, hip) in adult participants of Tehran lipid and glucose study (TLGS). In this cross-sectional study, 352 individuals (132 men and 220 women), age ≥19 years, were randomly recruited from participants of TLGS population. The serum levels of hs-CRP, IL-6, Hcy were determined using the enzyme linked immunosorbent assay (ELISA) method. Variables were compared by sample t-test. Bivariate linear correlation was estimated using Pearson's correlation coefficient. Linear regression analysis was applied to investigate the association between IMs and anthropometric and biochemical variables. The mean age of participants was 46.1±16.1 years. abdominal obesity was present in 199(56.5%) individuals. levels of hs-CRP and IL-6 increased in the abdominally obese group (1507±3.3 vs. 577.8±4.3 ng/ml P<0.001) (3.6±3.3 vs. 1.9±3.8 pg/ml P< 0.001), and in the same group, the best predictors for hs-CRP, IL-6 and Hcy were waist (WC), waist to height ratio (WHtR) and wrist respectively; hip and WHtR were the best predictors for Hcy and hs-CRP in the normal group. A linear augmentation in hs-CRP and IL-6 levels was observed in association with obesity categorizes. This study provides evidence that abdominally obese individuals had higher levels of IMs. Wrist, waist and WHtR were the best predictors for Hcy, hs-CRP and IL-6 respectively in this group.

    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.

    Full Text Available The American Heart Association supports an association between periodontal disease (PD and atherosclerotic vascular disease (ASVD but does not as of yet support a causal relationship. Recently, we have shown that major periodontal pathogens Porphyromonas gingivalis and Treponema denticola are causally associated with acceleration of aortic atherosclerosis in ApoEnull hyperlipidemic mice. The aim of this study was to determine if oral infection with another significant periodontal pathogen Fusobacterium nucleatum can accelerate aortic inflammation and atherosclerosis in the aortic artery of ApoEnull mice. ApoEnull mice (n = 23 were orally infected with F. nucleatum ATCC 49256 and euthanized at 12 and 24 weeks. Periodontal disease assessments including F. nucleatum oral colonization, gingival inflammation, immune response, intrabony defects, and alveolar bone resorption were evaluated. Systemic organs were evaluated for infection, aortic sections were examined for atherosclerosis, and inflammatory markers were measured. Chronic oral infection established F. nucleatum colonization in the oral cavity, induced significant humoral IgG (P=0.0001 and IgM (P=0.001 antibody response (12 and 24 weeks, and resulted in significant (P=0.0001 alveolar bone resorption and intrabony defects. F. nucleatum genomic DNA was detected in systemic organs (heart, aorta, liver, kidney, lung indicating bacteremia. Aortic atherosclerotic plaque area was measured and showed a local inflammatory infiltrate revealed the presence of F4/80+ macrophages and CD3+ T cells. Vascular inflammation was detected by enhanced systemic cytokines (CD30L, IL-4, IL-12, oxidized LDL and serum amyloid A, as well as altered serum lipid profile (cholesterol, triglycerides, chylomicrons, VLDL, LDL, HDL, in infected mice and altered aortic gene expression in infected mice. Despite evidence for systemic infection in several organs and modulation of known atherosclerosis risk factors, aortic

    To compare the effects of vildagliptin with those of glimepiride on glycaemic control, fat tolerance and inflammatory markers in people with Type 2 diabetes mellitus receiving metformin treatment. A total of 167 participants were randomized to vildagliptin 50 mg twice a day or glimepiride 2 mg three times a day, for 6 months. We evaluated the following variables: BMI; glycaemic control; fasting plasma insulin; homeostatic model assessment of insulin resistance index; fasting plasma proinsulin; glucagon; lipid profile; adiponectin; high-sensitivity C-reactive protein; interleukin-6; and tumour necrosis factor-α. A euglycaemic-hyperinsulinaemic clamp procedure and an oral fat load test were also performed. Despite a similar decrease in HbA1c levels (P = 0.009, and P = 0.008, respectively), body weight increased with glimepiride (P = 0.048 vs baseline) and decreased with vildagliptin (P = 0.041 vs baseline and vs glimepiride). Fasting plasma insulin and homeostatic model assessment of insulin resistance index were significantly lower with vildagliptin compared with glimepiride (P = 0.035 and 0.047). M value, an index of insulin sensitivity, increased with vildagliptin, both compared with baseline and with glimepiride (P = 0.028 and 0.039, respectively). Vildagliptin improved all post-oral fat load peaks of lipid profile compared with glimepiride. Adiponectin levels were higher (P = 0.035) and high-sensitivity C-reactive protein levels were lower (P = 0.038) with vildagliptin vs glimepiride. During the oral fat load test, interleukin-6, high-sensitivity C-reactive protein and tumour necrosis factor-α peaks were lower and adiponectin peak was higher in the vildagliptin group than in the glimepiride group. There was a higher dropout rate as a result of hypoglycaemia in the glimepiride group than in the vildagliptin group. Vildagliptin was more effective than glimepiride in reducing post-oral fat load peaks of lipid-trafficking adipocytokines and

    Full Text Available Objective: Type 2 diabetes (T2D is the primary case of chronic kidney disease (CKD. Inflammation is associated with metabolic dysregulation in patients with T2D and CKD. Tryptophan (TRP metabolism may have relevance to the CKD outcomes and associated symptoms. We investigated the relationships of TRP metabolism with inflammatory markers in patients with T2D and CKD. Methods: Data were collected from a well-characterized cohort of type 2 diabetic individuals with all stages of CKD, including patients on hemodialysis. Key TRP metabolites (kynurenine [KYN], kynurenic acid [KYNA], and quinolinic acid [QA], proinflammatory cytokines (tumor necrosis factor-α [TNF-α] and interleukin-6 [IL-6], and C-reactive protein were measured in plasma. The KYN/TRP ratio was utilized as a surrogate marker for indoleamine 2,3-dioxygenase 1 (IDO1 enzyme activity. Results: There was a significant inverse association between circulating TRP level and stages of CKD ( P  < 0.0001. Downstream bioactive TRP metabolites KYN, KYNA, and QA were positively and robustly correlated with the severity of kidney disease ( P  < 0.0001. In multiple linear regression, neither TNF-α nor IL-6 was independently related to KYN/TRP ratio after adjusting for estimated glomerular filtration rate (eGFR. Only TNF-α was independently related to KYN after taking into account the effect of eGFR. Conclusions: Chronic kidney disease secondary to T2D may be associated with accumulation of toxic TRP metabolites due to both inflammation and impaired kidney function. Future longitudinal studies to determine whether the accumulation of KYN directly contributes to CKD progression and associated symptoms in patients with T2D are warranted.

    Thrombomodulin (TM) is a membrane glycoprotein expressed on endothelial cells, which plays a major role in the protein C anticoagulation pathway. In people with inflammation, TM expression can be down-regulated on endothelial cells and a soluble form released into circulation, resulting in increased risk of thrombosis and disseminated intravascular coagulation. TM is present in dogs; however, there has been minimal investigation of its expression in canine tissues, and the effects of inflammation on TM expression in canine tissues have not been investigated. The objective of this study was to evaluate endothelial TM expression in tissues from dogs with systemic inflammatory diseases. A retrospective evaluation of tissue samples of lung, spleen, and liver from dogs with and without systemic inflammatory diseases was performed using immunohistochemistry (IHC) and a modified manual IHC scoring system. TM expression was significantly reduced in all examined tissues in dogs diagnosed with septic peritonitis or acute pancreatitis. © The Author(s) 2016.

    Abstract A chronic subclinical inflammatory status that coexists with immune dysfunction is commonly found in the elderly population. Consumption of foods rich in antioxidants (e.g., cherries) is an attractive strategy to reduce risk from chronic diseases. Based on previous studies showing the antioxidant effect of a Jerte Valley cherry derivative product in humans, the objective of this work was to evaluate the effect of the intake of a Jerte Valley cherry-based beverage on inflammatory load in both young and old ringdoves (Streptopelia risoria). To this purpose, circulating levels of pro-inflammatory and anti-inflammatory cytokines as well as serum levels of different acute-phase proteins were measured before and after a 10-day treatment with the Jerte Valley cherry-based beverage. Thus, the 10-day treatment with the cherry-based beverage modulated the balance of pro- and anti-inflammatory cytokines in both young and old ringdoves by down-regulating the levels of pro-inflammatory cytokines (interleukin [IL]-1β, tumor necrosis factor-α, and interferon-γ) and up-regulating the levels of anti-inflammatory cytokines (IL-4, IL-2, and IL-10). Moreover, the 10-day treatment with the Jerte Valley cherry-based product reduced the levels of several proteins involved in acute-phase responses, such as C-reactive protein, haptoglobin, α2-macroglobulin, and serum amyloid P component. On the other hand, old birds showed imbalanced levels of inflammatory markers toward a pro-inflammatory status, thereby underlining the fact that aging is usually accompanied by systemic inflammation and inflammation-related chronic diseases. To sum up, the data suggest a potential health benefit by consuming the cherry-based beverage, especially in aged populations, through their anti-inflammatory properties. PMID:22846077

    Our objective was to evaluate the short-term effects of calcium fructoborate (CFB) on gait, joint range of motion, serum inflammatory markers, and owner perception of pain in client-owned dogs. We used 59 osteoarthritic dogs with impairment, with dogs being randomly assigned to 4 treatments: placebo (60 mg fructose; = 15), low dose (69 mg CFB; = 14), high dose (127 mg CFB; = 14), or combination (69 mg CFB, 500 mg glucosamine hydrochloride and 200 mg chondroitin sulfate; = 16). Dogs up to 22.9 kg received 1 capsule/d, while dogs weighing 23 to 50 kg received 2 capsules/d. A physical examination, radiographs, goniometry measurements, gait analysis, blood sample collection, and a canine brief pain inventory questionnaire were performed on d 0 and 28. Change from baseline values were statistically analyzed among groups. After 28 d, dogs fed the low and high doses had an improved ( Dogs fed the high dose also had a greater ( = 0.05) increase in soluble receptor for advanced glycation end products concentration than dogs fed the placebo. Sub-analysis of only large dogs (> 23 kg) showed that dogs fed the low dose had decreased ( dogs fed the placebo. Large dogs fed the low dose also were shown to improve ( dogs fed the placebo. Overall, CFB supplementation was well-tolerated and may aid in mitigating joint discomfort in dogs.

    Full Text Available Background: We investigated the effects of Withania somnifera root (WS on insulin resistance, tumor necrosis factor α (TNF-α, and interleukin-6 (IL-6 in fructose-fed rats. Methods: Forty-eight Wistar-Albino male rats were randomly divided into four groups (n=12; Group I as control, Group II as sham-treated with WS by 62.5mg/g per diet, Group III fructose-fed rats received 10%W/V fructose, and Group IV fructose- and WS-fed rats. After eight weeks blood samples were collected to measure glucose, insulin, IL-6, and TNF-α levels in sera. Results: Blood glucose, insulin, homeostasis model assessment for insulin resistance (HOMA-R, IL-6, and TNF-α levels were all significantly greater in the fructose-fed rats than in the controls. Treatment with WS significantly (P < 0.05 inhibited the fructose-induced increases in glucose, insulin, HOMA-R, IL-6, and TNF-α. Conclusion: Our data suggest that WS normalizes hyperglycemia in fructose-fed rats by reducing inflammatory markers and improving insulin sensitivity.

    We aimed to evaluate the impact of low- or high-flux haemodialysis (HD) and online haemodiafiltration (OL-HDF) on inflammation and the lipid profile in HD patients. 50 HD patients were assigned to two groups for HD with low-flux (n = 25) or high-flux (n = 25) polysulphone dialysers for 6 weeks. Subsequently, all patients were haemodialysed with a low-flux polysulphone dialyser for 6 weeks, then transferred to OL-HDF for another 6 weeks. Blood samples for lipids and inflammatory markers (IL-6, IL-8, TNF-α, hs-CRP) were obtained at baseline and every 6 weeks. Changes in inflammatory markers and lipids from baseline to the 6-week dialysis period did not differ between low- and high-flux groups. When patients were transferred from low-flux HD to OL-HDF, IL-6, IL-8, and TNF-α levels significantly decreased whereas HDL and LDL cholesterol significantly increased. Low- and high-flux polysulphone membranes had similar effects on lipids and inflammatory markers, whereas OL-HDF potently reduced pro-inflammatory cytokines. Copyright © 2013 S. Karger AG, Basel.

    Depressed individuals not only suffer from chronic low grade inflammation, but also exhibit an inflammatory hyper-responsiveness to acute stress. We investigate whether chronic stress also induces an exaggerated inflammatory response in individuals with increased depression features. As model for chronic stress, social isolation was chosen. Interleukin (IL)-6 and hs-CRP levels were assessed in 1547 subjects (847 men and 700 women), derived from the population-based MONICA/KORA study. Standardized questionnaires were used to assess depressed mood (depression and exhaustion subscale) and social isolation (social network index). The relationship between the two inflammatory markers, social isolation and depressed mood was examined taking into account interactions social isolation × depressed mood using multivariable linear regression models, adjusted for age, BMI, smoking, alcohol, and physical activity. Analyses were performed in men and women separately. We observed a significant interaction between depressed mood and social isolation regarding IL-6 and hs-CRP, respectively in men (p-value=0.02 for IL-6 and social isolation, and depressed mood on inflammatory responses. Furthermore, depressed and socially isolated men had highly significantly elevated IL-6 levels (geometric mean: 3.76 vs. 1.92 pg/ml, p-value socially integrated men. In women, no significant associations were seen. The interaction of depressed mood and social isolation elicits a substantial synergistic impact on inflammatory markers in men, but not in depressed women. Copyright © 2011 Elsevier Inc.

    Even though IL-6 and MMP-9 are associated with airway inflammation in asthma, there is paucity of data in Indian population. To determine the levels of IL-6 and MMP-9 in the serum of patients suffering from asthma, and correlate with (a) disease severity, as per GINA guidelines; (b) clinical phenotypes; and (c) response to treatment. The levels of IL-6 and MMP-9 were compared between moderate persistent asthma (n = 25), severe persistent asthma (n = 25) and normal controls (n = 30). IL-6 and MMP-9 were measured by ELISA (R&D Systems Inc., USA and Canada) and compared between controls and asthmatics and between groups of different asthma severity, clinical variables, spirometry, and allergen sensitization. Spirometry was repeated after 2 months of ICS+LABA to assess response to treatment in relation to baseline IL-6 and MMP-9 levels. We observed a significant difference in both IL-6 and MMP-9 levels among asthmatics versus controls (p asthma (p asthma duration, total IgE, AEC, number of allergens sensitized and degree of sensitization. No significant correlation (p > 0.5) was observed with IL-6 and MMP-9 levels and FEV 1 improvement after 2 months of ICS+LABA. Higher levels of IL-6 and MMP-9 were observed in asthmatics as compared to controls and in severe persistent asthma as compared to moderate persistent asthma, higher levels of MMP-9 was associated with lower lung functions.

    This study investigates the extent to which sleep characteristics serve as predictor variables for inflammatory, hypothalamic-pituitary-adrenal and autonomic systems markers. Twenty-nine participants with a diagnosis of insomnia disorder based on the Diagnostic Statistical Manual of Mental Disorders, Fifth Edition (age 25.3 ± 1.6 years, insomnia duration 6.6 ± 0.8 years) and 19 healthy control sleepers (age 25.4 ± 1.4 years) underwent a 2-week at-home evaluation keeping a sleep diary and wearing an actigraph, followed by a visit to the Research Center to measure blood pressure, and collect blood and urine samples. The actigraphy- and diary-based variables of sleep duration, sleep-onset latency, wake after sleep onset and sleep fragmentation/number of night-time awakenings were averaged and entered as dependent variables in regression analyses. Composite scores were calculated for the autonomic (blood pressure, norepinephrine), inflammatory (monocyte counts, interleukin-6, C-reactive protein) and hypothalamic-pituitary-adrenal systems (cortisol), and used as predictor variables in regression models. Compared with controls, individuals with insomnia had a shorter sleep duration (P insomnia disorder, cortisol is upregulated and associated with actigraphy- and diary-based wake after sleep onset, suggesting that wake after sleep onset may serve as a marker to identify individuals at increased risks for disorders associated with a hyperactive hypothalamic-pituitary-adrenal system. The absence of autonomic and pro-inflammatory changes (interleukin-6, C-reactive protein), despite a substantial decrease in actigraphic sleep duration, may relate to a higher resilience to the adverse biological consequences of insomnia in this young age group. © 2014 European Sleep Research Society.

    Polycystic ovary syndrome (PCOS) is an endocrine disorder, afflicting females of reproductive age. This syndrome leads to infertility, insulin resistance, obesity, and cardiovascular problems, including a litany of other health issues. PCOS is a polygenic, polyfactorial, systemic, inflammatory, dysregulated steroid state, autoimmune disease, manifesting largely due to lifestyle errors. The advent of biochemical tests and ultrasound scanning has enabled the detection of PCOS in the affected females. Subsequently, a huge amount of insight on PCOS has been garnered in recent times. Interventions like oral contraceptive pills, metformin, and hormone therapy have been developed to bypass or reverse the ill effects of PCOS. However, lifestyle correction to prevent aberrant immune activation and to minimize the exposure to inflammatory agents, appears to be the sustainable therapy of PCOS. This holistic review with multiple hypotheses might facilitate to devise better PCOS management approaches. Copyright © 2018 Elsevier Ltd. All rights reserved.

    The role of adipokines in liver transplantation (LTx) recipients who have metabolic syndrome (MetS) has seldom been assessed. The aim of this study was to investigate the concentrations of adipokines, inflammatory mediators, and insulin-resistance markers in liver recipients with MetS and its components. Serum samples from 34 patients (55.9% male; 54.9 ± 13.9 y; 7.7 ± 2.9 y after LTx; 50% presented with MetS) were assessed for adiponectin, resistin, tumor necrosis factor (TNF)-α, monocyte chemoattractant protein (MCP)-1, interleukin (IL)-6, C-reactive protein (CRP), homeostatic model assessment-insulin resistance (HOMA-IR) and free fatty acid (FFA) levels. The dosages were uni- and multivariate analyzed to cover MetS (using the Harmonizing MetS criteria), its components, and dietary intake. A higher concentration of adiponectin (P < 0.05) was observed among patients with MetS (5.2 ± 3.2 μg/mL) compared with those without MetS (3.2 ± 1.2 μg/mL), as well as those with MetS components versus those without them: abdominal obesity (4.6 ± 2.6 μg/mL versus 2.6 ± 0.6 μg/mL), high triacylglycerols (TGs; 5.6 ± 3.1 μg/mL versus 3 ± 0.9 μg/mL) and low high-density lipoprotein (HDL; 6.1 ± 2.7 μg/mL versus 3.3 ± 1.9 μg/mL). Increased TNF-α and HOMA-IR values were seen in patients with abdominal obesity. Patients with high TGs also had greater FFA values. Independent predictors for adiponectin were waist-to-hip ratio, low HDL and high TGs. High TGs and fasting blood glucose were independent predictors for HOMA-IR. Independent predictors could not be identified for CRP, TNF-α, MCP-1, IL-6, or FFA. MetS and its components are related to an increased HOMA-IR concentration and FFA. Adiponectin, resistin, and inflammatory markers, such as TNF-α, IL-6, MCP-1, and CRP, were not associated with MetS in this sample of post-LTx patients. Copyright © 2016 Elsevier Inc.

    Studies are currently under way examining whether the age of stored red blood cells (RBCs) affects clinical outcome in transfusion recipients. The effects of storage duration on the RBC storage lesion are well documented, while fewer studies are available regarding the effect of RBC production method. In this study, we compared in vitro RBC quality variables and markers of inflammatory response in apheresis and whole blood (WB)-derived RBCs, specifically those prepared after an overnight room temperature hold (RTH) of WB. SAGM RBCs, prepared from WB after overnight RTH (n = 10), were compared to SAGM RBCs prepared using an apheresis device (Alyx, n = 10). As a control, SAGM RBCs were also prepared within 2 hours of WB collection (2-hr WB, n = 10). All RBCs were stored at 4°C for 42 days with weekly assay of in vitro variables, cytokines and/or chemokines, and neutrophil activation after incubation with RBC supernatant. RTH WB RBCs exhibited decreased levels of 2,3-diphosphoglycerate acid (2.3 μmol/g hemoglobin [Hb] ± 2.1 vs. 13.7 ± 1.3 μmol/g Hb) and morphology (160 ± 10 vs. 192 ± 5) on Day 1 and increased hemolysis (0.45 ± 0.21% vs. 0.31 ± 0.09%) and microparticles (6.1 ± 2.8/10(3) RBCs vs. 3.9 ± 1.1/10(3) RBCs) on Day 42 compared to apheresis RBCs. Gro-α and ENA-78 cytokine levels were significantly higher in RTH WB than Alyx RBCs during storage. CD11b expression was highest in neutrophils exposed to supernatant from RTH WB RBCs (p < 0.05). RBC preparation method has a meaningful effect on the RBC storage lesion, which should be taken into account in addition to length of storage. © 2013 American Association of Blood Banks.

    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.

    Although immune dysfunction in patients with cancer could be multifactorial, the immune system may be modulated by nutritional substrates and genetic background. Our study evaluated the effect of G308A polymorphism of the tumor necrosis factor-alpha (TNF-alpha) gene on inflammatory markers in patients after surgery for head and neck cancer who received early enteral nutrition. A population of 60 patients with oral and laryngeal cancer was enrolled. At surgery patients were treated with a hyperproteic enteral diet. Perioperatively and on postoperative day 6 the following parameters were evaluated: serum values of prealbumin, transferrin, total number of lymphocytes, interleukin-6, TNF-alpha, and C-reactive protein. In addition, genotyping of G308A gene polymorphism was assessed. Patients' mean age was 61.1 +/- 14.6 y (four women, 56 men) with a body mass index of 25.4 +/- 5.2 kg/m(2) and a previous weight loss of 0.35 +/- 0.2 kg. Forty patients (37 men, 3 women; 66.6%) had the genotype G308/G308 (wild group) and 20 patients (19 men, 1 woman; 23.4%) had the genotype G308/A308 (mutant group). A significant increase in prealbumin and transferrin levels was detected in both groups. C-reactive protein decreased in both groups (wild group: 105.1 +/- 60 versus 53.8 +/- 62.3 mg/dL, P < 0.05; mutant group: 99.5 +/- 46 versus 43.9 +/- 51.9 mg/dL, P < 0.05). Interleukin-6 decreased in both groups (wild group: 20.1 +/- 22 versus 6.2 +/- 4.1 pg/mL, P < 0.05; mutant group: 22.3 +/- 38 versus 9.2 +/- 7.4 pg/mL, P = NS). Lymphocytes increased in both groups (wild group: 1102 +/- 468 versus 1600 +/- 537 10(3)/mL, P = NS; mutant group: 1441 +/- 739 10(3)/mL versus 1669 +/- 614 10(6)/mL, P = NS). TNF-alpha showed no changes. The G308A polymorphism of the TNF-alpha gene did not affect levels of inflammatory markers in patients after surgery for head and neck cancer who were treated with early enteral nutrition.

    To examine the influence of walking at different times of day on lipids and inflammatory markers in sedentary patients with coronary artery disease (CAD). A total of 330 patients recruited from Nanjing between September 2011 and November 2012 were randomly assigned to a control group (n=110), morning (n=110) or evening walking group (n=110). Both the walking groups were asked to walk 30 min/day or more on at least 5 days/week either in the morning or evening for 12 weeks. Lipids and inflammatory markers were measured before and after exercise intervention. Compared with baseline, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were improved in all groups. Significances were shown in the changes of fibrinogen, high sensitivity C-reactive protein (hsCRP), white blood cell (WBC) count, TC, triglycerides, LDL-C, lipoprotein(a) between groups. The evening walking group had a larger decrease in fibrinogen (0.16 ± 0.19 g/L, Pwalking program successfully resulted in a favorable change in lipids and inflammatory markers. Patients in the evening walking group gained more benefits than those walking in the morning walking group. NCT01887093. © 2013.

    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.

  15. Mixed Marker-Based/Marker-Less Visual Odometry System for Mobile Robots

    2013-05-01

    Full Text Available Abstract When moving in generic indoor environments, robotic platforms generally rely solely on information provided by onboard sensors to determine their position and orientation. However, the lack of absolute references often leads to the introduction of severe drifts in estimates computed, making autonomous operations really hard to accomplish. This paper proposes a solution to alleviate the impact of the above issues by combining two vision-based pose estimation techniques working on relative and absolute coordinate systems, respectively. In particular, the unknown ground features in the images that are captured by the vertical camera of a mobile platform are processed by a vision-based odometry algorithm, which is capable of estimating the relative frame-to-frame movements. Then, errors accumulated in the above step are corrected using artificial markers displaced at known positions in the environment. The markers are framed from time to time, which allows the robot to maintain the drifts bounded by additionally providing it with the navigation commands needed for autonomous flight. Accuracy and robustness of the designed technique are demonstrated using an off-the-shelf quadrotor via extensive experimental tests.

    The relationship between diesel engine exhaust (DEE), a known lung carcinogen, and immune/inflammatory markers that have been prospectively associated with lung cancer risk is not well understood. To provide insight into these associations, we conducted a cross-sectional molecular epidemiology study of 54 males highly occupationally exposed to DEE and 55 unexposed male controls from representative workplaces in China. We measured plasma levels of 64 immune/inflammatory markers in all subjects using Luminex bead-based assays, and compared our findings to those from a nested case-control study of these markers and lung cancer risk, which had been conducted among never-smoking women in Shanghai using the same multiplex panels. Levels of nine markers that were associated with lung cancer risk in the Shanghai study were altered in DEE-exposed workers in the same direction as the lung cancer associations. Among these, associations with the levels of CRP (β= -0.53; P = 0.01) and CCL15/MIP-1D (β = 0.20; P = 0.02) were observed in workers exposed to DEE and with increasing elemental carbon exposure levels (Ptrends marker positively associated with an increased lung cancer risk, CCL2/MCP-1, were higher among DEE-exposed workers compared with controls in never and former smokers, but not in current smokers (Pinteraction = 0.01). The immunological differences in these markers in DEE-exposed workers are consistent with associations observed for lung cancer risk in a prospective study of Chinese women and may provide some insight into the mechanistic processes by which DEE causes lung cancer.

    Full Text Available Abstract The post-pericardiotomy syndrome (PPS is a common complication after cardiac surgery, occuring in 10-40% of patients. PPS may prolong hospitalization, and even serious complications like tamponade and constrictive pericarditis may occur. Early diagnosis and treatment may reduce morbidity. In 50 patients transferred to our hospital after cardiac surgery we found an increase in pro-inflammatory and a decrease in anti-inflammatory cytokines at admission in the patients later developing PPS compared to the patients who did not develop PPS. If confirmed in larger studies, these findings may prove useful in early identification of and targeted treatment in patients developing PPS.

    Preeclampsia is an inflammatory-mediated hypertensive disorder of pregnancy and seems to be an early indicator of increased cardiovascular risk, but mechanisms underlying this association are unclear. In this study, we identified levels of circulating inflammatory markers and dynamic changes in the systemic acute-phase response in 44 women with a history of severe early-onset preeclampsia, compared with 29 controls with only uneventful pregnancies at 1.5 to 3.5 years postpartum. Models used were in vivo seasonal influenza vaccination and in vitro whole-blood culture with T-cell stimulants and the toll-like receptor-4 ligand lipopolysaccharide. Outcome measures were C-reactive protein, interleukin-6 (IL-6), IL-18, fibrinogen, myeloperoxidase, and a panel of 13 cytokines representative of the innate and adaptive inflammatory response, in addition to established cardiovascular markers. The in vivo acute-phase response was higher for women with previous preeclampsia than that for controls without such a history, although only significant for C-reactive protein (P=0.04). Preeclampsia was associated with higher IL-1β (Ppreeclampsia: an adaptive response cluster associated with increased C-reactive protein and IL-6 before and after vaccination, increased weight, and low high-density lipoprotein cholesterol; and a toll-like receptor-4 mediated the cluster associated with increased IL-18 before and after vaccination but not associated with other cardiovascular markers. Furthermore, we found interactions between previous preeclampsia, common TLR4 gene variants, and the IL-18 response to vaccination. In conclusion, preeclampsia is associated with alterations in the inflammatory response postpartum mostly independent of other established cardiovascular risk markers. © 2015 American Heart Association, Inc.

The aim of this work was to investigate and compare selected biochemical parameters in patients with and without COPD. Observation group consisted of clinically stable patients with COPD (n = 60). The control group was healthy persons from the general population, without COPD, who were divided into two subgroups – smokers (n = 30) and non-smokers (n = 30). Laboratory parameters were investigated by automated clinical chemistry analyzer LISA 200th. Albumin in our measurements showed an average value of 39.55 g.l-1 in the patient population; 38.89 g.l-1 in smokers and in non-smokers group 44.65 g.l-1. The average value of pre-albumin in the group of patients was 0.28 ± 0.28 g.l-1 and 0.30 ± 0.04 g.l-1 in smokers group. The average value of the orosomucoid in patients was about 1.11 ± 0.90 mg.ml-1. In the group of smokers, the mean value of orosomucoid was 0.60 ± 0.13 mg.ml-1. The level of C-reactive protein (CRP) in the patient group reached an average value of 15.31 ± 22.04 mg.l-1, in the group of smokers was 5.18 ± 4.58 mg. l-1. Prognostic inflammatory and nutritional index (PINI) in the group of patients showed a mean value of 4.65 ± 10.77 and 0.026 ± 0.025 in smokers. The results of this work show, that the values of index PINI in COPD patients are significantly higher than in smokers (P COPD.

    This study profiled the local and systemic inflammatory responses to experimentally induced gingivitis. Eight females participated in a 21-day experimental gingivitis model followed by a 14-day resolution phase. Bleeding on probing and plaque index scores were assessed before, during, and after resolution of gingival inflammation, and samples of saliva, GCF, and plasma were collected. Samples were assessed for biomarkers of inflammation using the BioPlex platform and ELISA. There were no significant changes in GCF levels of cytokines during the experimental phase; however, individual variability in cytokine profiles was noted. During resolution, mean GCF levels of IL-2, IL-6, and TNF-α decreased and were significantly lower than baseline levels (P = 0.003, P = 0.025, and P = 0.007, resp.). Furthermore, changes in GCF levels of IL-2, IL-6, and TNF-α during resolution correlated with changes in plaque index scores (r = 0.88, P = 0.004; r = 0.72, P = 0.042; r = 0.79, P = 0.019, resp.). Plasma levels of sICAM-1 increased significantly during the experimental phase (P = 0.002) and remained elevated and significantly higher than baseline levels during resolution (P gingivitis adds to the systemic inflammatory burden of an individual.

    Full Text Available Background: Subclinical hypothyroidism (Sch is the most frequent thyroid disease. The relationship between overt hypothyroidism and cardiovascular diseases has been well documented, but conflicting data have remained regarding Sch. Objectives: The present study aimed to assess the effect of Sch on increasing the risk of cardiovascular involvement considering the autoimmune subset. Patients and Methods: This case-control study was conducted on thirty patients with Sch and 30 healthy controls. Serum levels of thyroperoxidase antibody (TPOab, lipids, hsCRP, homocysteine, and ferritin were measured. Besides, conventional echocardiographic study and tissue Doppler imaging (including strain rate indices was done to evaluate Left Ventricular (LV systolic function. Results: The results showed a significant difference between the Sch patients and the controls regarding the serum level of triglyceride (117.43 ± 63.51 mg/dL vs. 86.86 ± 41.57, P = 0.031, echocardiographic parameters (longitudinal systolic strain rate [SRs: -1.006 ± 0.4 vs. -1.26 ± 0.16, P = 0.002; SRl: -1.43 ± 0.27 vs. -1.68 ± 0.29, P = 0.001], and Sm of septal mitral annulus (6.90 ± 0.6 vs. 7.43 ± 0.8, P = 0.006]. However, no significant difference was observed between the two groups regarding the serum levels of the inflammatory markers. Moreover, a significant correlation was found between TSH and Sm (r = -0.36, P = 0.005 and longitudinal systolic strain rate (SRs: r = 0.42, P < 0.001; SRl: r = 0.40, P = 0.001. Systolic strain rate was significantly lower in the TPOab positive patients (-0.99 ± 0.18 vs. -1.15 ± 0.25, P = 0.047. Conclusions: The clear association between Sch and subclinical LV systolic dysfunction which was more evident in the subgroup of patients with circulating anti-thyroid antibodies would remind a greater emphasis for considering the subgroup of TPOab positive patients for directing toward hormone replacement.

    To identify and analyze the characteristics of the most influential articles about central nervous system (CNS) inflammatory demyelinating disease. The Institute for Scientific Information (ISI) Web of Science database and the 2014 Journal Citation Reports Science Edition were used to retrieve the top 100 cited articles on CNS inflammatory demyelinating disease. The citation numbers, journals, years of publication, authorships, article types, subjects and main issues were analyzed. For neuromyelitis optica (NMO), articles that were cited more than 100 times were regarded as a citation classic and described separately. The top 100 cited articles were published between 1972 and 2011 in 13 journals. The highest number of articles ( n  = 24) was published in Brain, followed by The New England Journal of Medicine ( n  = 21). The average number of citations was 664 (range 330-3,897), and 64% of the articles were from the United States and the United Kingdom. The majority of the top 100 cited articles were related to multiple sclerosis ( n  = 87), and only a few articles reported on other topics such as NMO ( n  = 9), acute disseminated encephalomyelitis ( n  = 2) and optic neuritis ( n  = 2). Among the top 100 cited articles, 77% were original articles. Forty-one citation classics were found for NMO. Our study provides a historical perspective on the research progress on CNS inflammatory demyelinating disease and may serve as a guide for important advances and trends in the field for associated researchers.

    Full Text Available The prognostic significance of sarcopenia, an important component of cancer cachexia, has been demonstrated in oncologic patients. Catabolic drivers have been suggested to be key features of cancer cachexia.To determine the relationship between systemic inflammatory markers and CT-determined muscle mass in patients with SCLC.Cross-sectional muscle areas were evaluated at the level of the third lumbar vertebra (L3 using baseline CT images in 186 SCLC patients. Sarcopenia was defined as a L3 muscle index (L3MI, muscle area at L3/height2 of < 55 cm2/m2 for men and of < 39 cm2/m2 for women. Systemic inflammatory markers investigated included serum white blood cell count (WBC, neutrophil: lymphocyte ratio (NLR, C-reactive protein (CRP, and albumin.Mean L3MI was 47.9 ± 9.7 cm2/m2 for men and 41.6 ± 7.0 cm2/m2 for women. Sarcopenia was present in 128 patients (68.8%, and sarcopenic patients had significant serum lymphocyte counts and albumin levels (p = 0.002 and 0.041, respectively, and higher NLRs and CRP levels (p = 0.011 and 0.026 than non-sarcopenic patients. Multivariable analysis revealed that CRP independently predicted L3MI (β = -0.208; 95% CI, -0.415 to -0.002; p = 0.048, along with gender and BMI (p values < 0.001 and performance status (p = 0.010.The present study confirms a significant linear relationship exists between CT-determined muscle mass and CRP in SCLC patients. This association might provide a better understanding of the mechanism of cancer cachexia.

    Purpose: To propose a simple model to explain the origin of ghost markers in marker-based optical tracking systems (OTS) and to develop retrospective strategies to detect and eliminate ghost markers. Methods: In marker-based OTS, ghost markers are virtual markers created due to the cross-talk between the two camera sensors, which can lead to system execution failure or inaccuracy in patient tracking. As a result, the users have to limit the number of markers and avoid certain marker configurations to reduce the chances of ghost markers. In this work, the authors propose retrospective strategies to detect and eliminate ghost markers. The two camera sensors were treated as mathematical points in space. The authors identified the coplanar within limit (CWL) condition as the necessary condition for ghost marker occurrence. A simple ghost marker detection method was proposed based on the model. Ghost marker elimination was achieved through pattern matching: a ghost marker-free reference set was matched with the optical marker set observed by the OTS; unmatched optical markers were eliminated as either ghost markers or misplaced markers. The pattern matching problem was formulated as a constraint satisfaction problem (using pairwise distances as constraints) and solved with an iterative backtracking algorithm. Wildcard markers were introduced to address missing or misplaced markers. An experiment was designed to measure the sensor positions and the limit for the CWL condition. The ghost marker detection and elimination algorithms were verified with samples collected from a five-marker jig and a nine-marker anthropomorphic phantom, rotated with the treatment couch from −60° to +60°. The accuracy of the pattern matching algorithm was further validated with marker patterns from 40 patients who underwent stereotactic body radiotherapy (SBRT). For this purpose, a synthetic optical marker pattern was created for each patient by introducing ghost markers, marker position

    Full Text Available Abstract The number of old and oldest old patients undergoing surgery of varying severity is increasing. Ageing is a process that changes the performances of most physiological systems and increases susceptibility to diseases and death; accordingly, host responses to surgical stress are altered with ageing and the occurrence of age-related increase in susceptibility to post-operative complications has been claimed. Twenty-four male patients undergoing Lichtenstein (LH hernioplasty for unilateral inguinal hernia were included in this study and divided in two groups (Young and Old respectively, according to their age. As expression of the acute phase response, we measured changes in concentration of pro-inflammatory cytokines Tumor necrosis factor-α and Interleukin-1β, leukocytes, acute phase proteins C-reactive protein and α 1-antitrypsin. Elderly humans showed prolonged and strong inflammatory activity compared to younger subjects in response to surgical stress, indicating that the acute-phase response to surgical stress of elderly humans varies from that of the young, showing initial hyperactivity and a delayed termination of the response. Thus, the acute phase response to surgical stress is higher in old subjects, but the clinical significance of this remains unclear. It is not known whether a causal relationship exists between this stronger acute phase response and the increases in susceptibility to post-operative complications observed in aged patients.

    Encysted cyathostomin larvae are ubiquitous in grazing horses. Arrested development occurs in this population and can lead to an accumulation of encysted larvae. Large numbers of tissue larvae place the horse at risk for developing larval cyathostominosis. This disease complex is caused by mass emergence of these larvae and is characterized by a generalized acute typhlocolitis and manifests itself as a profuse protein-losing watery diarrhea with a reported case-fatality rate of about 50%. Two anthelmintic formulations have a label claim for larvicidal therapy of these encysted stages; moxidectin and a five-day regimen of fenbendazole. There is limited knowledge about inflammatory and immunologic reactions to larvicidal therapy. This study was designed to evaluate blood acute phase reactants as well as gene expression of pro-inflammatory cytokines, both locally in the large intestinal walls and systemically. Further, mucosal tissue samples were evaluated histopathologically as well as analyzed for gene expression of pro- and anti-inflammatory cytokines, cluster of differentiation (CD) cell surface proteins, and select transcription factors. Eighteen juvenile horses with naturally acquired cyathostomin infections were randomly assigned to three treatment groups; one group served as untreated controls (Group 1), one received a five-day regimen of fenbendazole (10mg/kg) (Group 2), and one group received moxidectin (0.4mg/kg) (Group 3). Horses were treated on day 0 and euthanatized on days 18-20. Serum and whole blood samples were collected on days 0, 5, and 18. All horses underwent necropsy with collection of tissue samples from the ventral colon and cecum. Acute phase reactants measured included serum amyloid A, iron and fibrinogen, and the cytokines evaluated included interferon γ, tumor necrosis factor α, transforming growth factor (TGF)-β, and interleukins 1β, 4, 5, 6, and 10. Transcription factors evaluated were FoxP3, GATA3 and tBet, and CD markers included

    Full Text Available Colorectal cancer (CRC is the third leading cause of cancer death for both men and women in the United States, yet it is treatable and preventable. African Americans have higher incidence of CRC than other racial/ethnic groups, however, it is unclear whether this disparity is primarily due to environmental or biological factors. Short chain fatty acids (SCFAs are metabolites produced by bacteria in the colon and are known to be inversely related to CRC progression. The aim of this study is to investigate how stool SCFA levels, markers of inflammation in stool and dietary intake relate to colonoscopy findings in a diverse patient population. Stool samples from forty-eight participants were analyzed for SCFA levels and inflammatory markers (lysozyme, secretory IgA, lactoferrin. Additionally, participants completed the National Cancer Institute’s Diet History Questionnaire II (DHQ II to report dietary intake over the past year. Subsequently, the majority of participants underwent screening colonoscopy. Our results showed that African Americans had higher total levels of SCFAs in stool than other racial/ethnic groups, significantly lower intake of non-starchy vegetables and similar inflammatory marker expression and colonoscopy outcomes, compared to others. This work is an initial exploration into the biological and clinical factors that may ultimately inform personalized screening approaches and clinical decision-making to improve colorectal cancer disparities for African Americans.

    Personalized nutritional strategies to treat obesity may specifically influence inflammatory markers, in addition to reduce body weight. In the present study, we evaluated the effect of a hypocaloric diet based on a Mediterranean dietary pattern (MDP) on nutritional status as well as on plasma concentrations of retinol binding protein-4 (RBP4) and other proinflammatory markers. Fourty-one subjects (24F/17M; age: 37 ± 7 years; BMI: 32.2 ± 3.9 kg/m²) were assigned to follow a MDP within a caloric-restricted diet over an 8-week period. Anthropometrical, clinical, and biochemical variables were measured at baseline and endpoint after the nutritional program. Dietary intervention resulted in a mean weight loss of -4.4 ± 2.5 kg (P diet score from baseline was a significant and independent predictor factor for the decrease in plasma RBP4 concentration (P hypocaloric diet accompanying a high adherence to a MDP resulted in specific reductions on proinflammatory markers, in addition to a significant improvement in some metabolic syndrome features induced by weight loss, which could be a good combined strategy to treat obesity as well as related metabolic and inflammatory disorders.

    Standard treatment for inflammatory bowel diseases (IBD) necessitates frequent intake of anti-inflammatory and/or immunosuppressive drugs, leading to significant adverse events. To evaluate the role solid lipid nanoparticles (SLN) play as drug delivery system in enhancing anti-inflammatory activity for drugs such as dexamethasone and butyrate in a human inflammatory bowel diseases whole-blood model. ELISA assay and the peripheral blood mononuclear cell (PBMC) cytokine mRNA expression levels were evaluated by quantitative SYBR Green real-time RT-PCR to determine the IL-1beta, TNF-alpha, IFN-gamma and IL-10 secretion in inflammatory bowel diseases patients' PBMC culture supernatants. There was a significant decrease in IL-1beta (p<0.01) and TNF-alpha (p<0.001) secretion, whilst IL-10 (p<0.05) secretion significantly increased after cholesteryl butyrate administration, compared to that of butyrate alone at the highest concentration tested (100 microM), at 24h exposure. There was a significant decrease in IL-1beta (p<0.01), TNF-alpha (p<0.001) and IL-10 (p<0.001) secretion after dexamethasone loaded SLN administration, compared to dexamethasone alone at the highest concentration tested (250 nM) at 24h exposure. No IFN-gamma was detected under any conditions and no cytotoxic effects observed even at the highest concentration tested. The incorporation of butyrate and dexamethasone into SLN has a significant positive anti-inflammatory effect in the human inflammatory bowel disease whole-blood model. Copyright 2010 Elsevier B.V.

    Immune system abnormalities have been repeatedly observed in several psychiatric disorders, including severe depression and anxiety. However, whether specific immune mediators play an early role in the etiopathogenesis of these disorders remains unknown. In a longitudinal design, component-wise gradient boosting was used to build models of depression, assessed by the Mood-Feelings Questionnaire-Child (MFQC), and anxiety, assessed by the Screen for Child Anxiety Related Emotional Disorders (SCARED) in 254 adolescents from a large set of candidate predictors, including sex, race, 39 inflammatory proteins, and the interactions between those proteins and time. Each model was reduced via backward elimination to maximize parsimony and generalizability. Component-wise gradient boosting and model reduction found that female sex, growth- regulated oncogene (GRO), and transforming growth factor alpha (TGF-alpha) predicted depression, while female sex predicted anxiety. Differential onset of puberty as well as a lack of control for menstrual cycle may also have been responsible for differences between males and females in the present study. In addition, investigation of all possible nonlinear relationships between the predictors and the outcomes was beyond the computational capacity and scope of the present research. This study highlights the need for novel statistical modeling to identify reliable biological predictors of aberrant psychological behavior. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available Objective(s: The role of isoflavones in pulmonary structure and function during menopause is not well studied. Moreover, the important role of estrogen in the physiological function of respiratory system has been revealed. Genistein, as an isoflavone, mimics estrogenic in diabetic and ovariectomized rats. Here, we hypothesized that genistein would reverse changes in the protein expression levels related to estrogen deficiency in the lung of ovariectomized diabetic rats. Materials and Methods: Wistar female rats were assigned to four experimental groups (n=10 in each group: sham, rats underwent laparotomy without removing the ovaries; OVX, rats that underwent ovariectomy; OVX.D, rats underwent bilateral ovariectomy and were fed a high-fat diet (HFD; OVX.D.G, ovariectomized diabetic rats with genistein administration (1 mg/kg /day. After ovariectomy, rats continued to feed HFD for a 4-week period. After 4 weeks of HFD feeding, a single dose of 30 mg/kg of streptozotocin was administered in the diabetic group. Genistein was administered for eight weeks. At the end of the experiment, lung tissue was removed and Western blotting technique and hematoxylin-eosin staining were used for evaluation of the lung. Results: Treatment with genistein significantly decreased inflammatory and apoptotic biomarkers in the ovariectomized diabetic rats compared to non-treated animals (P

    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....

  20. 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.

    Inflammatory processes are putative mechanisms underlying the cardioprotective effects of physical activity. An inverse association between physical activity and inflammation has been demonstrated, but no long-term prospective data are available. We therefore examined the association between physical activity and inflammatory markers over a 10-year follow-up period. Participants were 4289 men and women (mean age, 49.2 years) from the Whitehall II cohort study. Self-reported physical activity and inflammatory markers (serum high-sensitivity C-reactive protein and interleukin-6) were measured at baseline (1991) and follow-up (2002). Forty-nine percent of the participants adhered to standard physical activity recommendations for cardiovascular health (2.5 h/wk moderate to vigorous physical activity) across all assessments. Physically active participants at baseline had lower C-reactive protein and interleukin-6 levels, and this difference remained stable over time. Compared with participants who rarely adhered to physical activity guidelines over the 10-year follow-up, the high-adherence group displayed lower log(e) C-reactive protein (β=-0.07; 95% confidence interval, -0.12 to -0.02) and log(e) interleukin-6 (β=-0.07; 95% confidence interval, -0.10 to -0.03) at follow-up after adjustment for a range of covariates. Compared with participants who remained stable, those who reported an increase in physical activity of at least 2.5 h/wk displayed lower log(e) C-reactive protein (β coefficient=-0.05; 95% confidence interval, -0.10 to -0.001) and log(e) interleukin-6 (β coefficient=-0.06; 95% confidence interval, -0.09 to -0.03) at follow-up. Regular physical activity is associated with lower markers of inflammation over 10 years of follow-up and thus may be important in preventing the proinflammatory state seen with aging.

    Background & objectives: The association between adiponectin and risk of cardiovascular disease is well known. The aim of the present study was to evaluate adiponectin and certain inflammatory markers and to determine the correlations between them in angiographically proven coronary artery disease (CAD) in subjects with and without diabetes. Methods: A total of 180 subjects who underwent coronary angiography for symptoms suggestive of CAD were categorised into groups based on their diabetes and/or CAD status: group1 (non-diabetic non-CAD); group2 (non-diabetic CAD); group3 (diabetic non-CAD) and group4 (diabetic CAD). Adiponectin, tumour necrosis factor α (TNF-α) and soluble form of E-selectin (sE-selectin) were estimated using quantitative sandwich enzyme immunoassay and high sensitive C-reactive protein (hsCRP) by particle enhanced immunoturbidimetric method. Results: Adiponectin levels were significantly lower in subjects with either diabetes or CAD and were much lower in subjects who had both. hsCRP was elevated in CAD and diabetes but did not differ significantly between groups. sE-selectin and TNF-α levels were elevated in CAD. Adiponectin negatively correlated with age, glucose, sE-selectin, total and LDL cholesterol. hsCRP correlated with BMI, sE-selectin and urea. sE-selectin correlated with BMI, triglycerides and VLDL cholesterol, whereas TNF-α correlated with fasting plasma glucose. In the logistic regression analysis, adiponectin had a significant inverse association with CAD. sE-selectin and TNF-α also showed significant independent association with CAD. Interpretation & conclusions: Adiponectin and other inflammatory markers such as sE-selectin and TNF-α showed a significant association with CAD. Hence, early assessment of such markers can help to identify high risk patients, and to reduce the inflammatory component of diabetes and CAD. PMID:25109718

    Allergic asthma is a chronic inflammatory disorder associated with elevated levels of immunoglobulin E (IgE), serum eosinophilic cationic protein (S-ECP), plasma eosinophil-derived neurotoxin (P-EDN) and fraction of exhaled nitric oxide (F E NO). Poor self-rated health and sickness behaviour has repeatedly been associated with inflammatory markers, but the nature of this relationship in chronic inflammatory disease is not known. Likewise, such findings largely rely on cross-sectional investigations. Self-rated health (How would you rate your general state of health?), sickness behaviour (mean rating of satisfaction with energy, sleep, fitness, appetite and memory), IgE, S-ECP, P-EDN, and F E NO were assessed in 181 non-smoking primary care patients with asthma in a 1-year longitudinal study. Associations between repeated measurements were calculated using mixed regression models and Spearman's correlations for change scores. Poor self-rated health was associated with high levels of seasonal IgE (p = 0.05) and food IgE (p = 0.04), but not total IgE or inflammatory markers. An increase over 1 year in perennial IgE was associated with a worsening of self-rated health (ρ = 0.16, p = 0.04). Poor self-rated health was associated with more pronounced sickness behaviour (p sickness behaviour was associated with a worsening of self-rated health over time (ρ = 0.21, p = 0.007). The study corroborates the importance of sickness behaviour as a determinant of self-rated health by showing that these factors co-vary over a 1-year period in a group of patients with allergic asthma. The importance of specific IgE for perceived health in primary care patients with mild to moderate asthma needs further investigation.

    Macrophages are heterogeneous and can polarize into specific subsets, e.g. pro-inflammatory M1-like and re-modelling M2-like macrophages. To determine if peritoneal macrophages (PEMs) or bone marrow derived macrophages (BMDMs) resembled aortic macrophages from ApoE-/- mice, their M1/M2 phenotype,......, ACSL1, SRB1, DGAT1, and cpt1a) was decreased in advanced versus early lesions. In conclusion, PEMs and BMDMs are phenotypically distinct and differ from macrophages in lesions with respect to expression of M1/M2 markers and lipid metabolism genes....

    Full Text Available Systemic inflammatory factors are inconsistently associated with the pathogenesis of chronic obstructive pulmonary disease (COPD. We conducted a systematic review and meta-analysis to summarize the evidence supporting the association between systemic inflammation and the risk of COPD. Pertinent studies were retrieved from PubMed, EmBase, and the Cochrane Library until April 2015. A random-effects model was used to process the data, and the analysis was further stratified by factors affecting these associations. Sensitivity analyses for publication bias were performed. We included 24 observational studies reporting data on 10,677 COPD patients and 28,660 controls. Overall, we noted that COPD was associated with elevated serum CRP (SMD: 1.21; 95%CI: 0.92-1.50; P < 0.001, leukocytes (SMD: 1.07; 95%: 0.25-1.88; P = 0.010, IL-6 (SMD: 0.90; 95%CI: 0.48-1.31; P < 0.001, IL-8 (SMD: 2.34; 95%CI: 0.69-4.00; P = 0.006, and fibrinogen levels (SMD: 0.87; 95%CI: 0.44-1.31; P < 0.001 when compared with control. However, COPD was not significantly associated with TNF-α levels when compared with control (SMD: 0.60; 95%CI: -0.46 to 1.67; P = 0.266. Our findings suggested that COPD was associated with elevated serum CRP, leukocytes, IL-6, IL-8, and fibrinogen, without any significant relationship with TNF-α.

    Unemployment represents for many affected individuals a substantial source of psychosocial stress, and is linked to both increased risk of morbidity and mortality and adverse health-related behaviours. Few studies have examined the association of unemployment with systemic inflammation, a plausible mediator of the associations of psychosocial stress and health, and results are mixed and context dependent. This study examines the association of unemployment with C-reactive protein (CRP) and fibrinogen, two markers of systemic inflammation. A random-effects meta-analysis was performed using a multilevel modelling approach, including 12 national UK surveys of working-age participants in which CRP and fibrinogen were measured between 1998 and 2012 (N=30,037 economically active participants). The moderating impact of participant age and UK country was explored. CRP and fibrinogen were elevated in unemployed compared to employed participants; jobseekers were also more likely (Odds Ratio: 1.39, p3mg/L), after adjustment for age, gender, education, long-term illness, smoking, and body mass index. Associations were not explained by mental health. Associations peaked in middle-age, and were stronger in Scotland and Wales than in England. Our study demonstrates that systemic inflammation is associated with an important but little-studied aspect of the social environment, as it is elevated in unemployed compared to employed survey participants. Modifications suggest the association of unemployment and inflammation is substantially influenced by contextual factors, and may be especially strong in Wales, where further investigation of this relationship is needed.

    Full Text Available Abstract Background WNV-associated encephalitis (WNVE is characterized by increased production of pro-inflammatory mediators, glial cells activation and eventual loss of neurons. WNV infection of neurons is rapidly progressive and destructive whereas infection of non-neuronal brain cells is limited. However, the role of neurons and pathological consequences of pro-inflammatory cytokines released as a result of WNV infection is unclear. Therefore, the objective of this study was to examine the role of key cytokines secreted by WNV-infected neurons in mediating neuroinflammatory markers and neuronal death. Methods A transformed human neuroblastoma cell line, SK-N-SH, was infected with WNV at multiplicity of infection (MOI-1 and -5, and WNV replication kinetics and expression profile of key pro-inflammatory cytokines were analyzed by plaque assay, qRT-PCR, and ELISA. Cell death was measured in SK-N-SH cell line in the presence and absence of neutralizing antibodies against key pro-inflammatory cytokines using cell viability assay, TUNEL and flow cytometry. Further, naïve primary astrocytes were treated with UV-inactivated supernatant from mock- and WNV-infected SK-N-SH cell line and the activation of astrocytes was measured using flow cytometry and ELISA. Results WNV-infected SK-N-SH cells induced the expression of IL-1β, -6, -8, and TNF-α in a dose- and time-dependent manner, which coincided with increase in virus-induced cell death. Treatment of cells with anti-IL-1β or -TNF-α resulted in significant reduction of the neurotoxic effects of WNV. Furthermore treatment of naïve astrocytes with UV-inactivated supernatant from WNV-infected SK-N-SH cell line increased expression of glial fibrillary acidic protein and key inflammatory cytokines. Conclusion Our results for the first time suggest that neurons are one of the potential sources of pro-inflammatory cytokines in WNV-infected brain and these neuron-derived cytokines contribute to WNV

    Full Text Available Chronic use of oral nonsteroidal anti-inflammatory drugs (NSAIDs is associated with increased risk of serious gastrointestinal side effects. Therefore, recent trends in the development of NSAIDs aim to reduce the incidence of side effects, and improve patient compliance. One of the strategies to improve efficacy and safety of oral NSAIDs is the development of combination products that contain gastroprotective agents. Several products containing NSAID in combination with proton pump inhibitors (ketoprofen/omeprazole, naproxen/esomeprazole, H2-receptor antagonists (ibuprofen/famotidine, and prostaglandin analogues (diclofenac/misoprostol are currently available on the market. Another approach refer to the special formulation design to allow dose reduction while preserving drug therapeutic efficacy. An example is SoluMatrix® technology, a manufacturing process that produce submicron-sized drug particles with enhanced dissolution and absorption properties. Patented SoluMatrix® technology has been successfully employed to develop low-dose diclofenac, meloxicam, indomethacin and naproxen products. Topical NSAID formulations enable drug delivery to target tissues, while reducing systemic exposure and concomitant side effects associated with oral NSAIDs. Dermal/transdermal NSAID delivery systems are subject of intensive investigation. So far, several 'advanced' drug delivery systems with diclofenac, ibuprofen and ketoprofen have been designed.

    The neutrophil-to-lymphocyte ratio has demonstrated to be a prognostic inflammatory marker in cardiovascular disease. The objective of this study is to evaluate the association between neutrophil-to-lymphocyte ratio and pathologic urinary albumin/creatinine ratio as an early marker of cardiovascular risk and systemic endothelial dysfunction, associated with microvascular disease, in asymptomatic subjects. A unicenter cross-sectional study was conducted, including 1816 asymptomatic subjects. Patients with previous cardiovascular disease, those who were treated with ACE inhibitors and/or angiotensin II receptor blockers and patients with albumin/creatinine ratio over 300mg/g were excluded. The outcome of the study was the presence of a pathologic urinary albumin/creatinine ratio. The neutrophil-to-lymphocyte ratio was significantly associated with altered urinary albumin/creatinine ratio in the univariate analysis and after adjustment for other known endothelial and cardiovascular risk factors (age, hypertension, dyslipidaemia, diabetes or altered glomerular filtration rate). Based on the sensitivity and specificity of different neutrophil-to-lymphocyte ratio thresholds, 3 risk groups were created for altered urinary albumin/creatinine ratio: low risk in those with neutrophil-to-lymphocyte ratio 3. These groups were found to have a statistically significant and independent prognostic power for altered urinary albumin/creatinine ratio in asymptomatic patients. The neutrophil-to-lymphocyte ratio appears to be a cost-efficient, non-invasive and independent potential marker of systemic endothelial dysfunction in asymptomatic subjects.

    Since the inflammatory response and oxidative stress are involved in the stroke cascade, we evaluated here the effects of Phycocyanobilin (PCB, the C-Phycocyanin linked tetrapyrrole) on PC12 cell survival, the gene expression and the oxidative status of hypoperfused rat brain. After the permanent bilateral common carotid arteries occlusion (BCCAo), the animals were treated with saline or PCB, taking samples 24 h post-surgery. Global gene expression was analyzed with GeneChip Rat Gene ST 1.1 from Affymetrix; the expression of particular genes was assessed by the Fast SYBR Green RT-PCR Master Mix and Bioplex methods; and redox markers (MDA, PP, CAT, SOD) were evaluated spectrophotometrically. The PCB treatment prevented the H{sub 2}O{sub 2} and glutamate induced PC12 cell injury assessed by the MTT assay, and modulated 190 genes (93 up- and 97 down-regulated) associated to several immunological and inflammatory processes in BCCAo rats. Furthermore, PCB positively modulated 19 genes mostly related to a detrimental pro-inflammatory environment and counteracted the oxidative imbalance in the treated BCCAo animals. Our results support the view of an effective influence of PCB on major inflammatory mediators in acute cerebral hypoperfusion. These results suggest that PCB has a potential to be a treatment for ischemic stroke for which further studies are needed. - Highlights: • Phycocyanobilin (PCB) prevents H{sub 2}O{sub 2} and glutamate induced PC12 cell viability loss. • Anterior cortex and striatum are highly vulnerable to cerebral hypoperfusion (CH). • PCB modulates 190 genes associated to inflammation in acute CH. • PCB regulates 19 genes mostly related to a detrimental pro-inflammatory environment. • PCB restores redox and immune balances showing promise as potential stroke therapy.

    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.

    Diabetes mellitus (DM) is a complex disease with alterations in metabolic and inflammatory markers. Stillman Salgado rats (eSS) spontaneously develop type 2 DM by middle age showing progressive impairment of glucose tolerance with hyperglycemia, hypertriglyceridemia and hyperinsulinemia. We analyzed the effects of supplementation of ω-3 and ω-6 polyunsaturated fatty acids (PUFAs) with or without nordihydroguaiaretic acid (NDGA) added, an antioxidant and lipoxygenase inhibitor, on metabolic and inflammatory parameters in eSS rats to evaluate whether they can delay development and/or prevent progression of DM. After weaning, eSS rats received, intraperitoneally, once a month ω-3 (EPA 35% and DHA 40%-6.25 mg/Kg) or ω-6 (90% arachidonic acid- 6. 25 mg/Kg) for twelve months. Two additional groups of rats received 1.9 mg/kg NDGA added to ω-3 and ω-6 fatty acids. Blood samples were collected at day 40, and at the end of the 6th month and 12th month of age to determine plasma triglycerides (TGs), total plasma fatty acids (FA), A1C hemoglobin (HbA1C), C-reactive protein (CRP), gamma glutamyl transpeptidase (GGT), lipo and hydro peroxides, nitrites and IL-6 (in plasma and liver, kidney, and pancreas) and underwent oral glucose tolerance test (OGTT) as well. Wistar and eSS rats that received saline solution were used as controls. Plasma lipids profile, TG, fasting and post-prandial blood glucose levels, and glycosylated HbA1C showed significant improvements in ω-3 and ω-3 + NDGA treated animals compared to eSS control group. ω-3 and ω-3 + NDGA groups showed an inverse correlation with fasting blood glucose and showed lower plasma levels of GGT, TG, and CRP. eSS rats treated with ω-3 LCPUFAs showed reduced level of inflammatory and oxidative indices in plasma and liver, kidney and pancreas tissues in comparison with eSS control (non-treated) and ω-6 treated groups. eSS rats are a useful model to study type 2 DM pathophysiology and related inflammatory

    Evidence suggests that testicular cancer (TC) and its treatment are associated with cognitive impairment. However, the underlying neural substrate and biological mechanisms are poorly understood. This study aimed to investigate changes in cognition and brain grey matter (GM) morphology in TC patients undergoing treatment, and to explore associations with immune markers, endocrine markers, and genotype. Sixty-five patients with stage I-III TC underwent assessment after surgery but prior to further treatment and again 6 months after. Twenty-two patients received chemotherapy (+CT), while 43 did not (-CT). Assessments included neuropsychological testing, whole-brain magnetic resonance imaging, and blood samples. Twenty-five healthy controls (HCs) underwent neuropsychological testing with a matching time interval. A regression-based approach was used to determine cognitive changes and longitudinal voxel-based morphometry (VBM) was performed to investigate changes in GM density in the TC groups. Compared with the HCs, both TC groups showed higher rates of cognitive decline (p < 0.05). A trend towards greater decline was observed in + CT (63.6 %) compared with -CT patients (39.5 %) (p = 0.07). VBM revealed widespread GM reductions in both TC groups, but a group-by-time interaction analysis revealed prefrontal reductions specific to the + CT group (p = 0.02), which were associated with poorer cognitive performance. Poorer cognitive performance was also associated with an increase in tumor necrosis factor alpha in + CT patients. Furthermore, an interaction effect was found between the APOE ε4 genotype and chemotherapy on cognitive performance with ε4 carriers performing significantly worse. These findings provide novel evidence of changes in cognition and brain morphology in TC patients undergoing treatment.

    Full Text Available BACKGROUND: Vitamin D deficiency has been suggested as a cardiovascular risk factor, but little is known about underlying mechanisms or associations with inflammatory or hemostatic markers. Our aim was to investigate the association between 25-hydroxyvitamin D [25(OHD, a measure for vitamin D status] concentrations with pre-clinical variations in markers of inflammation and hemostasis. METHODOLOGY/PRINCIPAL FINDINGS: Serum concentrations of 25(OHD, C-reactive protein (CRP, fibrinogen, D-dimer, tissue plasminogen activator (tPA antigen, and von Willebrand factor (vWF were measured in a large population based study of British whites (aged 45 y. Participants for the current investigation were restricted to individuals free of drug treated cardiovascular disease (n = 6538. Adjusted for sex and month, 25(OHD was inversely associated with all outcomes (p or =75 nmol/l compared to < 25 nmol/l. D-dimer concentrations were lower for participants with 25(OHD 50-90 nmol/l compared to others (quadratic term p = 0.01. We also examined seasonal variation in hemostatic and inflammatory markers, and evaluated 25(OHD contribution to the observed patterns using mediation models. TPA concentrations varied by season (p = 0.02, and much of this pattern was related to fluctuations in 25(OHD concentrations (p < or =0.001. Some evidence of a seasonal variation was observed also for fibrinogen, D-dimer and vWF (p < 0.05 for all, with 25(OHD mediating some of the pattern for fibrinogen and D-dimer, but not vWF. CONCLUSIONS: Current vitamin D status was associated with tPA concentrations, and to a lesser degree with fibrinogen and D-dimer, suggesting that vitamin D status/intake may be important for maintaining antithrombotic homeostasis.

  20. Systemic inflammatory response syndromes in the era of interventional cardiology.

    2018-04-12

    Systemic inflammatory response syndrome (SIRS), initially reported after cardiovascular surgery, has been described after various interventional cardiology procedures, including endovascular/thoracic aortic repair (EVAR/TEVAR), implantation of heart rhythm devices, percutaneous coronary intervention (PCI), electrophysiology procedures (EP), and transcatheter aortic valve implantation (TAVI). In these settings, a comprehensive understanding of the triggers, pathogenesis as well as a common diagnostic/therapeutic algorithm is lacking and will be discussed in this review. SIRS occurs in about 40% and 50% of patients undergoing TEVAR/EVAR and TAVI respectively; it affects 0.1% of patients undergoing implantation of heart rhythm devices. Prevalence is unknown after PCI or EP. Clinical presentation includes fever, dyspnoea/tachypnoea, tachycardia, weakness, chest pain and pericardial/pleural effusion. Several triggers can be identified, related to implanted devices, biomaterial, and procedural aspects (prolonged hypotension, aneurysm thrombus manipulation, active fixation atrial leads, coronary microembolization, balloon dilatation/stent implantantation, contrast medium, coronary/myocardial microperforation). Nonetheless, these triggers share three main pathogenic pathways leading to SIRS clinical manifestations: leucocytes activation, endothelial injury/activation, and myocardial/pericardial injury. Therapy consists of non-steroidal agents, with corticosteroids as second-line treatment in non-responders. Although a benign evolution is reported after implantation of heart rhythm devices, PCI and EP, major adverse events may occur after EVAR/TEVAR and TAVI at short- and mid-term follow up.

    BACKGROUND: Tourniquet-induced reperfusion injury in animals produces significant systemic inflammatory effects. This study investigated whether a biologic response occurs in a clinically relevant model of tourniquet-induced reperfusion injury. METHODS: Patients undergoing elective knee arthroscopy were prospectively randomized into controls (no tourniquet) and subjects (tourniquet-controlled). The effects of tourniquet-induced reperfusion on monocyte activation state, neutrophil activation state, and transendothelial migration (TEM) were studied. Changes in the cytokines implicated in reperfusion injury, tumor necrosis factor-alpha, interleukin (IL)-1beta, and IL-10 were also determined. RESULTS: After 15 minutes of reperfusion, neutrophil and monocyte activation were significantly increased. Pretreatment of neutrophils with pooled subject (ischemia-primed) plasma significantly increased TEM. In contrast, TEM was not significantly altered by ischemia-primed plasma pretreatment of the endothelial monolayer. Significant elevation of tumor necrosis factor-alpha and IL-1beta were observed in subjects compared with controls after 15 minutes of reperfusion. There was no significant difference in serum IL-10 levels between the groups at all the time points studied. CONCLUSION: These results indicate a transient neutrophil and monocyte activation after tourniquet-ischemia that translates into enhanced neutrophil transendothelial migration with potential for tissue injury.

    The study was undertaken to investigate whether regular cooking with biomass aggravates systemic inflammation and oxidative stress that might result in increase in the risk of developing cardiovascular disease (CVD) in rural Indian women compared to cooking with a cleaner fuel like liquefied petroleum gas (LPG). A total of 635 women (median age 36 years) who cooked with biomass and 452 age-matched control women who cooked with LPG were enrolled. Serum interleukin-6 (IL-6), C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α) and interleukin-8 (IL-8) were measured by ELISA. Generation of reactive oxygen species (ROS) by leukocytes was measured by flow cytometry, and erythrocytic superoxide dismutase (SOD) was measured by spectrophotometry. Hypertension was diagnosed following the Seventh Report of the Joint Committee. Tachycardia was determined as pulse rate > 100 beats per minute. Particulate matter of diameter less than 10 and 2.5 μm (PM 10 and PM 2.5 , respectively) in cooking areas was measured using real-time aerosol monitor. Compared with control, biomass users had more particulate pollution in indoor air, their serum contained significantly elevated levels of IL-6, IL-8, TNF-α and CRP, and ROS generation was increased by 37% while SOD was depleted by 41.5%, greater prevalence of hypertension and tachycardia compared to their LPG-using neighbors. PM 10 and PM 2.5 levels were positively associated with markers of inflammation, oxidative stress and hypertension. Inflammatory markers correlated with raised blood pressure. Cooking with biomass exacerbates systemic inflammation, oxidative stress, hypertension and tachycardia in poor women cooking with biomass fuel and hence, predisposes them to increased risk of CVD development compared to the controls. Systemic inflammation and oxidative stress may be the mechanistic factors involved in the development of CVD. -- Highlights: ► Effect of chronic biomass smoke exposure on cardiovascular health was

  4. Trauma-induced systemic inflammatory response versus exercise-induced immunomodulatory effects.

    Fehrenbach, Elvira; Schneider, Marion E

    2006-01-01

    Accidental trauma and heavy endurance exercise, both induce a kind of systemic inflammatory response, also called systemic inflammatory response syndrome (SIRS). Exercise-related SIRS is conditioned by hyperthermia and concomitant heat shock responses, whereas trauma-induced SIRS manifests concomitantly with tissue necrosis and immune activation, secondarily followed by fever. Inflammatory cytokines are common denominators in both trauma and exercise, although there are marked quantitative differences. Different anti-inflammatory cytokines may be involved in the control of inflammation in trauma- and exercise-induced stress. Exercise leads to a balanced equilibrium between inflammatory and anti-inflammatory responses. Intermittent states of rest, as well as anti-oxidant capacity, are lacking or minor in trauma but are high in exercising individuals. Regular training may enhance immune competence, whereas trauma-induced SIRS often paves the way for infectious complications, such as sepsis.

    The aim of this study was to evaluate the relation of three new inflammatory markers with presence and severity of preeclampsia and to compare the predictive values of all markers for presence of this setting. In this study, a total of 100 consecutive pregnants with a diagnosis of preeclampsia and 40 healthy pregnants between October 2014 and April 2015 were included. Epicardial fat tissue was calculated by two-dimensional transthoracic echocardiography, and pentraxin-3 and neutrophil-to-lymphocyte ratio were measured by using an enzyme-linked immunosorbent assay method and routine blood count analysis, respectively. Epicardial fat thickness (p preeclampsia as compared to the healthy pregnants. Furthermore, epicardial fat thickness (p = 0.002), pentraxin-3 (p preeclampsia compared to mild preeclampsia. In the multivariate analysis, epicardial fat thickness (p = 0.013), pentraxin-3 (p = 0.04), and neutrophil-to-lymphocyte ratio (p preeclampsia after adjusting for other risk factors. Epicardial fat thickness, neutrophil-to-lymphocyte ratio, and pentraxin-3 are important markers that provide an additional information beyond that provided by conventional methods in predicting presence and severity of preeclampsia.

    This study was aimed to evaluate the cardioprotective potential of combination of T. arjuna and α-tocopherol in isoproterenol induced myocardial injury. Wistar albino rats were pre-treated with hydroalcoholic extract of T. arjuna (HETA) and α-tocopherol (100 mg/kg b. w) daily for 30 days. Isoproterenol (ISP, 85 mg/kg b.w) was administered on 28th and 29th days at an interval of 24 hr. ISP treated rats showed significant increase in lipid peroxidation (MDA), cardiac markers (CK-MB, SGOT, Trop I and LDH), pro-inflammatory cytokine (IL-6, CRP, TNF-α) levels and apoptotic markers (Bcl-2/Bax) as compared to healthy group. Pre-treatment with HETA 100 mg/kg b. w, reduced the elevated levels of these markers and significant effect (ppresent study concluded that the combination of α-tocopherol (100 mg/kg b. w) and hydroalcoholic extract of T. arjuna (100 mg/kg b. w) augments endogenous antioxidant compounds of rat heart and also prevents the myocardium from ISP-induced myocardial injury and it may have therapeutic and prophylactic value in the treatment of ischemic heart disease.

    We propose an intelligent vision-based Automated Guided Vehicle (AGV) system using fiduciary markers. In this paper, we explore a low-cost, efficient vehicle guiding method using a consumer grade web camera and fiduciary markers. In the proposed method, the system uses fiduciary markers with a capital letter or triangle indicating direction in it. The markers are very easy to produce, manipulate, and maintain. The marker information is used to guide a vehicle. We use hue and saturation values in the image to extract marker candidates. When the known size fiduciary marker is detected by using a bird's eye view and Hough transform, the positional relation between the marker and the vehicle can be calculated. To recognize the character in the marker, a distance transform is used. The probability of feature matching was calculated by using a distance transform, and a feature having high probability is selected as a captured marker. Four directional signals and 10 alphabet features are defined and used as markers. A 98.87% recognition rate was achieved in the testing phase. The experimental results with the fiduciary marker show that the proposed method is a solution for an indoor AGV system.

  11. Reduced nasal nitric oxide production in cystic fibrosis patients with elevated systemic inflammation markers.

    Directory of Open Access Journals (Sweden)

    Ruth K Michl

    Full Text Available BACKGROUND: Nitric oxide (NO is produced within the respiratory tract and can be detected in exhaled bronchial and nasal air. The concentration varies in specific diseases, being elevated in patients with asthma and bronchiectasis, but decreased in primary ciliary dyskinesia. In cystic fibrosis (CF, conflicting data exist on NO levels, which are reported unexplained as either decreased or normal. Functionally, NO production in the paranasal sinuses is considered as a location-specific first-line defence mechanism. The aim of this study was to investigate the correlation between upper and lower airway NO levels and blood inflammatory parameters, CF-pathogen colonisation, and clinical data. METHODS AND FINDINGS: Nasal and bronchial NO concentrations from 57 CF patients were determined using an electrochemical analyser and correlated to pathogen colonisation of the upper and lower airways which were microbiologically assessed from nasal lavage and sputum samples. Statistical analyses were performed with respect to clinical parameters (lung function, BMI, laboratory findings (CRP, leucocytes, total-IgG, fibrinogen, and anti-inflammatory and antibiotic therapy. There were significant correlations between nasal and bronchial NO levels (rho = 0.48, p<0.001, but no correlation between NO levels and specific pathogen colonisation. In patients receiving azithromycin, significantly reduced bronchial NO and a tendency to reduced nasal NO could be found. Interestingly, a significant inverse correlation of nasal NO to CRP (rho = -0.28, p = 0.04 and to leucocytes (rho = -0.41, p = 0.003 was observed. In contrast, bronchial NO levels showed no correlation to clinical or inflammatory parameters. CONCLUSION: Given that NO in the paranasal sinuses is part of the first-line defence mechanism against pathogens, our finding of reduced nasal NO in CF patients with elevated systemic inflammatory markers indicates impaired upper airway defence. This

    To determine whether biomarkers of inflammation and endothelial dysfunction are associated with the development of kidney dysfunction and the time frame of their association. Biomarkers were measured at four time points during 28 years of treatment and follow-up in patients with type 1 diabetes in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) cohort. In addition to traditional biomarkers of inflammation (C-reactive protein and fibrinogen), we measured interleukin-6 (IL-6) and soluble tumor necrosis factor receptors 1 and 2 (sTNFR-1/2), markers of endothelial dysfunction (soluble intracellular adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin [sE-selectin]), and fibrinolysis (total and active plasminogen activator inhibitor-1 [PAI-1]). Renal outcomes were defined as progression to incident chronic kidney disease (stage 3 or more severe) or macroalbuminuria (albumin excretion rate ≥300 mg/24 h). Prospective multivariate event-time analyses were used to determine the association of each biomarker with each subsequent event within prespecified intervals (3-year and 10-year windows). Multivariate event-time models indicated that several markers of inflammation (sTNFR-1/2), endothelial dysfunction (sE-selectin), and clotting/fibrinolysis (fibrinogen and PAI-1) are significantly associated with subsequent development of kidney dysfunction. Although some markers showed variations in the associations between the follow-up windows examined, the results indicate that biomarkers (sTNFR-1/2, sE-selectin, PAI-1, and fibrinogen) are associated with progression to chronic kidney disease in both the 3-year and the 10-year windows. Plasma markers of inflammation, endothelial dysfunction, and clotting/fibrinolysis are associated with progression to kidney dysfunction in type 1 diabetes during both short-term and long-term follow-up. © 2017 by the American Diabetes Association.

  14. Association of Lung Inflammatory Cells with Small Airways Function and Exhaled Breath Markers in Smokers - Is There a Specific Role for Mast Cells?

    Directory of Open Access Journals (Sweden)

    Yvonne Nussbaumer-Ochsner

    Full Text Available Smoking is associated with a mixed inflammatory infiltrate in the airways. We evaluated whether airway inflammation in smokers is related to lung function parameters and inflammatory markers in exhaled breath.Thirty-seven smokers undergoing lung resection for primary lung cancer were assessed pre-operatively by lung function testing including single-breath-nitrogen washout test (sb-N2-test, measurement of fractional exhaled nitric oxide (FeNO and pH/8-isoprostane in exhaled breath condensate (EBC. Lung tissue sections containing cancer-free large (LA and small airways (SA were stained for inflammatory cells. Mucosal (MCT respectively connective tissue mast cells (MCTC and interleukin-17A (IL-17A expression by mast cells was analysed using a double-staining protocol.The median number of neutrophils, macrophages and mast cells infiltrating the lamina propria and adventitia of SA was higher than in LA. Both MCTC and MCT were higher in the lamina propria of SA compared to LA (MCTC: 49 vs. 27.4 cells/mm2; MCT: 162.5 vs. 35.4 cells/mm2; P<0.005 for both instances. IL-17A expression was predominantly detected in MCTC of LA. Significant correlations were found for the slope of phase III % pred. of the sb-N2-test (rs= -0.39, for the FEV1% pred. (rs= 0.37 and for FEV1/FVC ratio (rs=0.38 with MCT in SA (P<0.05 for all instances. 8-isoprostane concentration correlated with the mast cells in the SA (rs=0.44, there was no correlation for pH or FeNO with cellular distribution in SA.Neutrophils, macrophages and mast cells are more prominent in the SA indicating that these cells are involved in the development of small airway dysfunction in smokers. Among these cell types, the best correlation was found for mast cells with lung function parameters and inflammatory markers in exhaled breath. Furthermore, the observed predominant expression of IL-17A in mast cells warrants further investigation to elucidate their role in smoking-induced lung injury, despite the

    Full Text Available Orthopedic implants have become essential components of modern medicine. The risk of infection of total hip arthroplasty (THA is 1.5%−2%. Are the C-reactive protein (CRP, the erythrocyte sedimentation rate (ESR, and procalcitonin (PCT good markers for THA infection screenings? From February 2009 to December 2012 at our Department of Orthopedics and Traumatology, 1248 patients were treated with THA. No prosthesis was cemented. All patients received antibiotic prophylaxis. All patients were discharged approximately 7.4 days after surgery with this clinical and radiographic follow-up program at 15 days and 1, 3, 6, 12, 24, and 36 months after surgery. Blood samples to determine ESR, CRP, and PCT values were taken at 1 hour before surgery and 15 days and 1, 3, 6, 12, 24, and 36 months after surgery. During follow-ups there were 22 cases of THA infections; according the Widmer classification, infections are hematogenous ones in 16 cases, late chronic ones in 5 cases, and early postoperative ones in 1 case. In all cases the three markers were considered positive; in 6 cases there were no radiological signs of septic loosening. ESR, CRP, and PCT proved to have a greater diagnostic accuracy than X-rays in predicting late chronic and early postoperative infections. These markers are valuable support for the surgeon in monitoring the prosthetic implant lifespan.

    Idiopathic inflammatory-demyelinating diseases (IIDDs) include a broad spectrum of central nervous system disorders that can usually be differentiated on the basis of clinical, imaging, laboratory and pathological findings. However, there can be a considerable overlap between at least some of these disorders, leading to misdiagnoses or diagnostic uncertainty. The relapsing-remitting and secondary progressive forms of multiple sclerosis (MS) are the most common IIDDs. Other MS phenotypes include those with a progressive course from onset (primary progressive and progressive relapsing) or with a benign course continuing for years after onset (benign MS). Uncommon forms of IIDDs can be classified clinically into: (1) fulminant or acute IIDDs, such as the Marburg variant of MS, Balo's concentric sclerosis, Schilder's disease, and acute disseminated encephalomyelitis; (2) monosymptomatic IIDDs, such as those involving the spinal cord (transverse myelitis), optic nerve (optic neuritis) or brainstem and cerebellum; and (3) IIDDs with a restricted topographical distribution, including Devic's neuromyelitis optica, recurrent optic neuritis and relapsing transverse myelitis. Other forms of IIDD, which are classified clinically and radiologically as pseudotumoral, can have different forms of presentation and clinical courses. Although some of these uncommon IIDDs are variants of MS, others probably correspond to different entities. MR imaging of the brain and spine is the imaging technique of choice for diagnosing these disorders, and together with the clinical and laboratory findings can accurately classify them. Precise classification of these disorders may have relevant prognostic and treatment implications, and might be helpful in distinguishing them from tumoral or infectious lesions, avoiding unnecessary aggressive diagnostic or therapeutic procedures.

Other forms of IIDD, which are classified clinically and radiologically as pseudotumoral, can have different forms of presentation and clinical courses. Although some of these uncommon IIDDs are variants of MS, others probably correspond to different entities. MR imaging of the brain and spine is the imaging technique of choice for diagnosing these disorders, and together with the clinical and laboratory findings can accurately classify them. Precise classification of these disorders may have relevant prognostic and treatment implications, and might be helpful in distinguishing them from tumoral or infectious lesions, avoiding unnecessary aggressive diagnostic or therapeutic procedures.

    Inflammation and immobility are comorbid etiological factors inducing muscle weakness in critically ill patients. This study establishes a rat model to examine the effect of inflammation and immobilization alone and in combination on muscle contraction, histology, and acetylcholine receptor regulation. Prospective, randomized, experimental study. Animal laboratory of a university hospital. Sprague-Dawley rats. To produce systemic inflammation, rats (n = 34) received three consecutive intravenous injections of Corynebacterium parvum on days 0, 4, and 8. Control rats (n = 21) received saline. Both groups were further divided to have one hind limb either immobilized by pinning of knee and ankle joints or sham-immobilized (surgical leg). The contralateral nonsurgical leg of each animal served as control (nonsurgical leg). After 12 days, body weight and muscle mass were significantly reduced in all C. parvum animals compared with saline-injected rats. Immobilization led to local muscle atrophy. Normalized to muscle mass, tetanic contraction was reduced in the surgical leg after immobilization (7.64 +/- 1.91 N/g) and after inflammation (8.71 +/- 2.0 N/g; both p < .05 vs. sham immobilization and saline injection, 11.03 +/- 2.26 N/g). Histology showed an increase in inflammatory cells in all C. parvum-injected animals. Immobilization in combination with C. parvum injection had an additive effect on inflammation. Acetylcholine receptors were increased in immobilized muscles and in all muscles of C. parvum-injected animals. The muscle weakness in critically ill patients can be replicated in our novel rat model. Inflammation and immobilization independently lead to muscle weakness.

    Full Text Available Malgorzata J Podolska, Mona HC Biermann, Christian Maueröder, Jonas Hahn, Martin Herrmann Department of Internal Medicine 3, Institute for Clinical Immunology and Rheumatology, Friedrich-Alexander University of Erlangen-Nuremberg, Erlangen, Germany Abstract: The immune system struggles every day between responding to foreign antigens and tolerating self-antigens to delicately maintain tissue homeostasis. If self-tolerance is broken, the development of autoimmunity can be the consequence, as it is in the case of the chronic inflammatory autoimmune disease systemic lupus erythematosus (SLE. SLE is considered to be a multifactorial disease comprising various processes and cell types that act abnormally and in a harmful way. Oxidative stress, infections, or, in general, tissue injury are accompanied by massive cellular demise. Several processes such as apoptosis, necrosis, or NETosis (formation of Neutrophil Extracellular Traps [NETs] may occur alone or in combination. If clearance of dead cells is insufficient, cellular debris may accumulate and trigger inflammation and leakage of cytoplasmic and nuclear autoantigens like ribonucleoproteins, DNA, or histones. Inadequate removal of cellular remnants in the germinal centers of secondary lymphoid organs may result in the presentation of autoantigens by follicular dendritic cells to autoreactive B cells that had been generated by chance during the process of somatic hypermutation (loss of peripheral tolerance. The improper exposure of nuclear autoantigens in this delicate location is consequently prone to break self-tolerance to nuclear autoantigens. Indeed, the germline variants of autoantibodies often do not show autoreactivity. The subsequent production of autoantibodies plays a critical role in the development of the complex immunological disorder fostering SLE. Immune complexes composed of cell-derived autoantigens and autoantibodies are formed and get deposited in various tissues, such as the

    We wish to assist caretakers with a sensor monitoring systems for tracking the physiological changes of homealone patients. One goal is seeking biomarkers and modern imaging sensors like stochastic optical reconstruction microscopy (STORM), which has achieved visible imaging at the nano-scale range. Imaging techniques like STORM can be combined with a fluorescent functional marker in a system to capture the early transformation signs from wellness to illness. By exploiting both microscopic knowledge of genetic pre-disposition and the macroscopic influence of epigenetic factors we hope to target these changes remotely. We adopt dual spectral infrared imaging for blind source separation (BSS) to detect angiogenesis changes and use laser speckle imaging for hypertension blood flow monitoring. Our design hypothesis for the monitoring system is guided by the user-friendly, veteran-preferred "4-Non" principles (noninvasive, non-contact, non-tethered, non-stop-to-measure) and by the NIH's "4Ps" initiatives (predictive, personalized, preemptive, and participatory). We augment the potential storage system with the recent know-how of video Compressive Sampling (CSp) from surveillance cameras. In CSp only major changes are saved, which reduces the manpower cost of caretakers and medical analysts. This CSp algorithm is based on smart associative memory (AM) matrix storage: change features and detailed scenes are written by the outer-product and read by the inner product without the usual Harsh index for image searching. From this approach, we attempt to design an effective household monitoring approach to save healthcare costs and maintain the quality of life of seniors.

    INTRODUCTION: Circulating levels of the inflammatory marker YKL-40 are elevated in cardiovascular disease and obesity-related type 2 diabetes (T2D), and serum YKL-40 levels are related to elements of dyslipidaemia. OBJECTIVE: We aimed to investigate the associations between serum YKL-40 and obesity...... glucose tolerance tests for estimation of glucose tolerance and surrogate measures of insulin sensitivity. Anthropometric measures were retrieved and biochemical measures of the plasma lipid profile and serum YKL-40 levels were obtained. Association-analyses between serum YKL-40 and obesity-related traits...... and estimates of the narrow sense heritability of YKL-40 were based on a polygenic variance component model. RESULTS: Fasting serum levels of YKL-40 were positively associated with waist-hip-ratio (pfasting plasma triglyceride levels (p

    To assess the effect of ginger consumption on glycemic status, lipid profile and some inflammatory markers in patients with type 2 diabetes mellitus. In a double-blinded, placebo-controlled clinical trial, 70 type 2 diabetic patients were enrolled. They allocated randomly into ginger group and control group. They consumed 1600 mg ginger versus 1600 mg wheat flour placebo daily for 12 weeks. Serum sugar, lipids, CRP, PGE2 and TNFα were measured before and after intervention. Ginger reduced fasting plasma glucose, HbA1C, insulin, HOMA, triglyceride, total cholesterol, CRP and PGE₂ significantly compared with placebo group (p  0.05). Ginger improved insulin sensitivity and some fractions of lipid profile, and reduced CRP and PGE₂ in type 2 diabetic patients. Therefore ginger can be considered as an effective treatment for prevention of diabetes complications.

    Physical activity is important in obesity prevention, but the effectiveness of different physical activity modalities remains to be determined among children. The main purpose of this study was to compare the effects of a 6-month soccer programme and a traditional physical activity programme on changes in body composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitness and perceived psychological status in obese boys. Eighty-eight boys (8-12 years; BMI > +2 standard deviations of WHO reference values) participated in one of three groups: soccer, traditional activity and control. Soccer and traditional activity programmes involved 3 sessions per week for 60-90 min at an average intensity of 70-80% of maximal heart rate. Control group participated in activities of normal daily living. All boys participated in school physical education, two sessions per week of 45-90-min. Measurements were taken at baseline and after 6 months, and included body size and composition, cardiometabolic risk factors, inflammatory and oxidative markers, cardiorespiratory fitness and perceived psychological status. Physical activity and dietary intake were assessed before and immediately following the intervention. The three groups had similar characteristics at baseline. After 6 months, both intervention groups had significantly lower relative fatness (% fat), waist circumference and total cholesterol, and higher cardiorespiratory fitness, self-esteem, perceived physical competence and attraction to physical activity compared with control group. In conclusion, physical activity interventions over 6 months positively influenced several indicators of health status among obese boys. The results also suggested that soccer has the potential as an effective tool for the prevention and reduction of childhood obesity and associated consequences.

    The present study was designed to investigate the association of four inflammatory markers and five periodontal indexes with the risk of coronary heart disease (CHD) in 131 patients with type 2 diabetes mellitus (T2DM). All subjects were inpatients, including 63 T2DM patients with comorbid CHD ("cases") and 68 T2DM patients without CHD ("controls"). The diagnosis of CHD is based on coronary angiography. Peripheral blood concentrations of high sensitivity C-reactive protein (hs-CRP) (11.51 vs. 10.39 mg/L), leptin (24.60 vs. 21.22 ng/L) and visfatin (65.92 vs. 57.62 ng/L) were significantly higher in cases than in controls (P = .033, 0.041 and 0.041, respectively). The levels of three periodontal indexes - probing pocket depth, attachment loss (AL) and sulcus bleeding index, were significantly higher in cases than in controls, especially for periodontal AL (3.60 mm vs. 3.29 mm, P = .002). A Forward logistic regression was performed for selection, and specifically hs-CRP, leptin, visfatin and periodontal AL were found to be associated with the significant risk of CHD (odds ratio: 1.16, 1.07, 1.03 and 2.04; P = .025, .022, .022 and .010, respectively). Importantly, the benefits of inflammatory markers and periodontal indexes over basic risk factors were significant (likelihood ratio test) and obvious (decision curve analysis). A nomogram was delineated based on significant variables, and it had good accuracy (C-index: 0.801, P periodontal indexes to the pathogenesis of CHD in T2DM. Specifically, hs-CRP, leptin, visfatin and periodontal AL were identified as significant contributors. Copyright © 2017 Elsevier B.V. All rights reserved.

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.

    Grain dust is well known to cause both acute and chronic respiratory disorders, and endotoxins are considered key components in this. Since endotoxins are known to elicit proinflammatory mediators, we investigated cytokine (tumor necrosis factor [TNF], interleukin-6, interleukin-8) release and a number of proinflammatory and anti-inflammatory proteins (soluble TNF receptors, lipopolysaccharide (LPS) binding protein, bactericidal permeability increasing protein (BPI), C-reactive protein) in plasma of workers exposed to grain dust. In two surveys during 1 week, lung function was measured daily before and after the shift, using flow-volume curves and/or forced oscillation measurements. On Monday and Friday, blood samples (30 mL) were drawn and cytokine release was determined by enzyme-linked immunosorbent assay in supernatant of isolated monocytes or whole blood culture, either unstimulated or on the ex vivo stimulation with 3 ng/mL or 1,000 ng/mL endotoxin. Individual exposures were determined from stationary dust measurements at every workplace combined with personal task analysis during all shifts. In both surveys, no cross-week change in lung function parameters was observed. In the first survey (average exposure: 20.2 mg/m3), monocyte spontaneous TNF release was increased sevenfold cross week (pdust exposure (r=0.62) of that week and the increase in soluble TNF receptor 75 kD (r=0.85). In the second survey, where average exposure was much lower (3.67 mg/m3), impedance parameters indicated a significant improvement of airway function, and cross-week changes in inflammatory markers were minimal. Therefore, we conclude that inflammatory events can be used to monitor adverse respiratory effects of moderate grain dust exposure.

    Chemokines are involved in the remodeling of the heart; however, their significance as biomarkers in heart failure is unknown. We observed that circulating CXCR3 receptor chemokines CXCL9 and CXCL10 in a rat model of heart failure were increased 1 week after myocardial infarction. CXCL10 was also increased in both remote and infarcted regions of the heart and remained elevated at 16 weeks; CXCL9 was elevated in the remote area at 1 week. In humans, hierarchical clustering and principal component analysis revealed that circulating CXCL10, MIP-1α, and CD40 ligand were the best indicators for differentiating healthy and heart failure subjects. Serum CXCL10 levels were increased in patients with symptomatic heart failure as indexed by NYHA classification II through IV. The presence of CXCL10, MIP-1α, and CD40 ligand appears to be dominant in patients with advanced heart failure. These findings identify a distinct profile of inflammatory mediators in heart failure patients

    Maternal inflammation undergoes adaptations during pregnancy, and excessive inflammation has been associated with adverse outcomes. One mechanism may be maternal inflammation transmission to the fetal compartment. Links between maternal pregnancy inflammation and fetal inflammation are poorly characterized. Principal components analysis was used to extract underlying inflammation components across cytokines (IFN-γ, IL-10, IL-13, IL-6, IL-8, TNF-α) in two pregnancy cohorts (SPAH N=87, MOMS N=539) assessed during the second and third trimesters. Links between maternal inflammation over pregnancy and fetal (cord blood) inflammation were assessed. Substantial cytokine rank-order stability was observed in both cohorts, β's range .47-.96, P's blood inflammation, P's>.04. Maternal inflammation indices over pregnancy were associated with inflammation in cord blood at birth. Results have implications for understanding pregnancy inflammatory processes and how maternal inflammation may be transmitted to fetal circulation. © 2016 John Wiley & Sons A/S.

    The consensus definition of severe sepsis requires suspected or proven infection, organ failure, and signs that meet two or more criteria for the systemic inflammatory response syndrome (SIRS). We aimed to test the sensitivity, face validity, and construct validity of this approach. We studied data from patients from 172 intensive care units in Australia and New Zealand from 2000 through 2013. We identified patients with infection and organ failure and categorized them according to whether they had signs meeting two or more SIRS criteria (SIRS-positive severe sepsis) or less than two SIRS criteria (SIRS-negative severe sepsis). We compared their characteristics and outcomes and assessed them for the presence of a step increase in the risk of death at a threshold of two SIRS criteria. Of 1,171,797 patients, a total of 109,663 had infection and organ failure. Among these, 96,385 patients (87.9%) had SIRS-positive severe sepsis and 13,278 (12.1%) had SIRS-negative severe sepsis. Over a period of 14 years, these groups had similar characteristics and changes in mortality (SIRS-positive group: from 36.1% [829 of 2296 patients] to 18.3% [2037 of 11,119], P<0.001; SIRS-negative group: from 27.7% [100 of 361] to 9.3% [122 of 1315], P<0.001). Moreover, this pattern remained similar after adjustment for baseline characteristics (odds ratio in the SIRS-positive group, 0.96; 95% confidence interval [CI], 0.96 to 0.97; odds ratio in the SIRS-negative group, 0.96; 95% CI, 0.94 to 0.98; P=0.12 for between-group difference). In the adjusted analysis, mortality increased linearly with each additional SIRS criterion (odds ratio for each additional criterion, 1.13; 95% CI, 1.11 to 1.15; P<0.001) without any transitional increase in risk at a threshold of two SIRS criteria. The need for two or more SIRS criteria to define severe sepsis excluded one in eight otherwise similar patients with infection, organ failure, and substantial mortality and failed to define a transition point in

    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.

    Objectives: Autophagy constitutes a defense mechanism to overcome aging and apoptosis in osteoarthritic cartilage. Several cytokines and transcription factors are linked to autophagy and play an important role in the degradative cascade in osteoarthritis (OA). Cell therapy such as platelet rich plasma (PRP) has recently emerged as a promising therapeutic tool for many diseases including OA. However, its mechanism of action on improving cartilage repair remains to be determined. The purpose of this study is to investigate the effect of PRP on osteoarthritic chondrocytes and to elucidate the mechanism by which PRP contributes to cartilage regeneration. Methods: Osteoarthritic chondrocytes were co-cultured with an increasing concentration of PRP obtained from healthy donors. The effect of PRP on the proliferation of chondrocytes was performed using cell counting and WST8 proliferation assays. Autophagy, apoptosis and intracellular level of IL-4, IL-10, and IL-13 were determined using flow cytometry analyses. Autophagy markers BECLIN and LC3II were also determined using quantitative polymerase chain reaction (qPCR). qPCR and ELISA were used to measure the expression of ADAMDTS-5, MMP3, MMP13, TIMP-1–2–3, aggregan, Collagen type 2, TGF-β, Cox-2, Il-6, FOXO1, FOXO3, and HIF-1 in tissues and co-cultured media. Results: PRP increased significantly the proliferation of chondrocytes, decreased apoptosis and increased autophagy and its markers along with its regulators FOXO1, FOXO3 and HIF-1 in osteoarthritic chondrocytes. Furthermore, PRP caused a dose-dependent significant decrease in MMP3, MMP13, and ADAMTS-5, IL-6 and COX-2 while increasing TGF-β, aggregan, and collagen type 2, TIMPs and intracellular IL-4, IL-10, IL-13. Conclusion: These results suggest that PRP could be a potential therapeutic tool for the treatment of OA. - Highlights: • Platelet Rich Plasma is suggested as a new treatment for osteoarthritis. • The proposed therapeutic effect is

    Full Text Available Abstract Background Monocytes and neutrophils are examples of phagocytic leukocytes, with neutrophils being considered as the 'chief' phagocytic leukocyte. Both monocytes and neutrophils have been implicated to play a key role in the development of ischaemia-reperfusion injury, where they are intrinsically involved in leukocyte-endothelial cell interactions. In this pilot study we hypothesised that mild episodes of tourniquet induced forearm ischaemia-reperfusion injury results in leukocyte activation and changes in inflammatory and coagulation markers. Methods Ten healthy human volunteers were recruited after informed consent. None had any history of cardiovascular disease with each subject volunteer participating in the study for a 24 hour period. Six venous blood samples were collected from each subject volunteer at baseline, 10 minutes ischaemia, 5, 15, 30, 60 minutes and 24 hours reperfusion, by means of a cannula from the ante-cubital fossa. Monocyte and neutrophil leukocyte sub-populations were isolated by density gradient centrifugation techniques. Leukocyte trapping was investigated by measuring the concentration of leukocytes in venous blood leaving the arm. The cell surface expression of CD62L (L-selectin, CD11b and the intracellular production of hydrogen peroxide (H2O2 were measured via flow cytometry. C-reactive protein (CRP was measured using a clinical chemistry analyser. Plasma concentrations of D-dimer and von Willebrand factor (vWF were measured using enzyme-linked fluorescent assays (ELFA. Results During ischaemia-reperfusion injury, there was a decrease in CD62L and an increase in CD11b cell surface expression for both monocytes and neutrophils, with changes in the measured parameters reaching statistical significance (p =2O2 production by leukocyte sub-populations, which was measured as a marker of leukocyte activation. Intracellular production of H2O2 in monocytes during ischaemia-reperfusion injury reached statistical

    Oxidative stress and inflammation contribute as a key factor for retarding the process of dermal wound healing. Trianthema portulcastrum Linn. (TP) leaves reported to possess antioxidant, antifungal, anti-inflammatory and antibacterial properties, which could make TP a promising wound healing agent. The current study was aimed to estimate the antioxidant potential of the fractionated hydroethanolic extract of TP leaves and evaluate wound healing activity by excision and incision wound models along with the assessment of possible underlying mechanism. Ethyl acetate, chloroform and n-butanol fractions of the hydroethanolic extract of TP leaves were examined for in vitro antioxidant ability by DPPH method. Strongest antioxidant activity bearing n-butanol fraction (nBuTP) was further analyzed quantitatively by High Performance Liquid Chromatography coupled with Diode Array Detector (HPLC-DAD). Wound healing potential of nBUTP using excision and incision wound model was studied. Wistar albino rats were randomly divided into four groups, containing six animals in each group; group I served as control treated with simple ointment base, group II was standard group, treated with povidone-iodine ointment USP (5%), group III treated with nBuTP 5% w/w ointment, and group IV treated with nBuTP 10%w/w ointment. All the groups were topically applied their respective ointments, once daily, till the complete healing achieved. Wound healing was assessed by analyzing % wound closure, hydroxyproline content, epithelialization period, tensile strength, enzymatic antioxidative status and inflammatory markers. Total phenolic and flavonoid content of the extract was estimated to be 112.32±1.12 and 84.42±0.47mg/g, respectively. HPLC-DAD of nBuTP confirmed the presence of chlorogenic acid (20.74±0.03), protocatechuic acid (34.45±0.02mg/g), caffeic acid (4.31±0.03mg/g) and ferulic acid (1.43±0.01mg/g). 5% and 10%w/w nBuTP ointment significantly accelerated the wound healing process

    Full Text Available Abstract Background Heartworm disease in dogs is a life-threatening parasitic disease. Although adulticide treatment with melarsomine has been proven to be the most effective, complications associated with adulticide treatment are major concerns for clinicians. Methods This study evaluated the change in levels of D-dimer, interleukin-6, C-reactive protein and cardiac troponin I in 12 dogs with different severities of heartworm infection treated by the American Heartworm Society (AHS recommended protocol during the treatment period. The serum levels of several markers were measured on the day of diagnosis (T-60, before the initiation of melarsomine therapy (T0, 1 day after the first injection (T1, 1 week after the first injection (T7, 1 month after the first injection (T30, 1 day after the second injection (T31, 1 day after the third injection (T32, 1 week after the third injection (T39, 1 month after the third injection (T62, 2 months after the third injection (T92, 3 months after the third injection (T122, and 6 months after the third injection (T182. Results The serum levels of these markers were significantly different at the test time point after melarsomine treatment and also differed significantly according to the stage of heartworm disease in the dogs. Conclusion This study found that monitoring of inflammatory and hemostatic markers in dogs with heartworm disease being treated with melarsomine might be beneficial in predicting the clinical outcomes and complications associated with melarsomine treatment.

    This review summarizes present evidence for the role of YKL-40 in the diagnosis, prognosis and cause of cardiovascular and alcoholic liver disease. The question of whether YKL-40 is merely a marker or a causal factor in the development of cardiovascular and liver disease is addressed, with emphasis...... of cardiovascular and alcoholic liver disease, thus suggesting that plasma YKL-40 does not play a causal role in the development of these diseases. Despite this, plasma YKL-40 levels may play a role in disease progression after diagnosis, and inhibition of YKL-40 activity might be a novel therapy in some...... rather than a drug and placebo, and like a blinded trial, it allows inference about causality. Moreover, the review also covers background on the molecular biology and functions of YKL-40, YKL-40 levels in healthy individuals and reference range, and the role of YKL-40 as a biomarker of cardiovascular...

    obesity, was associated with the severity of inflammatory regions in prostate tissue and with LUTS severity among men with inflammation. Our results suggest centralized obesity advances prostate tissue inflammation to increase LUTS severity. Clinically targeting centralized fat deposition may reduce LUTS severity. Mechanistically, the lack of a clear relationship between systemic inflammatory or oxidative stress markers in blood or urine with prostate size or LUTS suggests pathways other than systemic inflammatory signaling may link body adiposity to BPH outcomes.

    Inflammatory bowel diseases (IBD) are associated with an altered systemic immune response leading to inflammation-mediated damage to the gut and other organs. Oral immune therapy is a method of systemic immune modulation via alteration of the gut immune system. It uses the inherit ability of the innate system of the gut to redirect the systemic innate and adaptive immune responses. Oral immune therapy is an attractive clinical approach to treat autoimmune and inflammatory disorders. It can induce immune modulation without immune suppression, has minimal toxicity and is easily administered. Targeting the systemic immune system via the gut immune system can serve as an attractive novel therapeutic method for IBD. This review summarizes the current data and discusses several examples of oral immune therapeutic methods for using the gut immune system to generate signals to reset systemic immunity as a treatment for IBD.

    This study aimed to evaluate the effect of vitamin D3 megadose supplementation and influence of BsmI polymorphism in the VDR gene on the inflammatory profile and oxidative stress in elderly women with vitamin D deficiency. A double blind, randomized, placebo-controlled trial was conducted with 40 elderly women (aged 68±6 years) diagnosed with vitamin D insufficiency (24.7±3.1 ng/mL). Participants were distributed into a supplementation group that received 200,000 IU of vitamin D3 (SG; n=20) and a placebo group (PG; n=20). Blood samples were collected at baseline and after intervention to analyse the 25(OH)D, parathyroid hormone, serum calcium, ultra-sensitive C-reactive protein (us-CRP), alpha 1-acid glycoprotein (AGP-A), total antioxidant capacity (TAC), and malondialdehyde (MDA) levels, as well as the renal and hepatic function, and genotyping was performed for BsmI polymorphism. Four weeks after supplementation, elderly women in the SG group showed a significant increase in the serum concentration of 25(OH)D (25.29±2.8 to 31.48±6.0; p=0.0001), which was followed by increased TAC (65.25±15.66 to 71.83±10.71; p=0.03) and decreased serum PTH (46.32±13.2 to 35.45±11.0; p=0.009), us-CRP (0.38±0.3 to 0.19±0.1; p=0.007) and AGP-A levels (75.3±15.4 to 61.1±5.9; p=0.005). Changes in BP, ANAC and MDA were not observed. The 25(OH)D and PTH, us-CRP and AGP-A levels of participants with the BB/Bb genotype were more responsive to supplementation, but their other markers did not change. Supplementation with a vitamin D3 megadose reduced inflammatory markers and increased the total antioxidant capacity in elderly women with vitamin D insufficiency. The 25(OH)D, PTH, us-CRP and AGP-A levels of elderly patients with the BB/Bb genotype were more responsive to supplementation compared with those with the bb genotype. Copyright © 2015 Elsevier Inc.

    Systemic inflammation and poor nutritional status have a negative effect on the outcomes of cancer. Here, we analyzed the effects of the pretreatment inflammatory and nutritional status on clinical outcomes of locally advanced non-small-cell lung cancer (NSCLC) patients treated with chemoradiotherapy. We retrospectively reviewed 89 patients with locally advanced NSCLC treated with chemoradiotherapy between July 2006 and June 2013. Serum C-reactive protein (CRP) was assessed as an inflammatory marker, and serum albumin, body mass index (BMI) and skeletal mass index were assessed as nutritional status markers. The relationships between these markers and overall survival (OS) were assessed. The median OS was 24.6 months [95% confidence interval (CI): 19.4–39.3 months]. During follow-up, 58 patients (65%) had disease recurrence and 52 patients (58%) died. In multivariate Cox hazard analysis, CRP levels and BMI approached but did not achieve a significant association with OS (P = 0.062 and 0.094, respectively). Recursive partitioning analysis identified three prognostic groups based on hazard similarity (CRP-BMI scores): 0 = CRP < 0.3 mg/dl, 1 = CRP ≥ 0.3 mg/dl and BMI ≥ 18.5 kg/m 2 , and 2 = CRP ≥ 0.3 mg/dl and BMI < 18.5 kg/m 2 . The CRP-BMI score was significantly associated with OS (P = 0.023). Patients with scores of 0, 1 and 2 had median OS of 39.3, 24.5 and 14.5 months, respectively, and the scores also predicted the probability of receiving salvage treatment after recurrence. The CRP-BMI score is thus a simple and useful prognostic marker of clinical outcome for patients with locally advanced NSCLC treated with chemoradiotherapy.

    Full Text Available Abstract Background Traumatic brain injury (TBI initiates interrelated inflammatory and coagulation cascades characterized by wide-spread cellular activation, induction of leukocyte and endothelial cell adhesion molecules and release of soluble pro/antiinflammatory cytokines and thrombotic mediators. Resuscitative care is focused on optimizing cerebral perfusion and reducing secondary injury processes. Hypertonic saline is an effective osmotherapeutic agent for the treatment of intracranial hypertension and has immunomodulatory properties that may confer neuroprotection. This study examined the impact of hypertonic fluids on inflammatory/coagulation cascades in isolated head injury. Methods Using a prospective, randomized controlled trial we investigated the impact of prehospital resuscitation of severe TBI (GCS vs 0.9% normal saline (NS, on selected cellular and soluble inflammatory/coagulation markers. Serial blood samples were drawn from 65 patients (30 HSD, 35 NS at the time of hospital admission and at 12, 24, and 48-h post-resuscitation. Flow cytometry was used to analyze leukocyte cell-surface adhesion (CD62L, CD11b and degranulation (CD63, CD66b molecules. Circulating concentrations of soluble (sL- and sE-selectins (sL-, sE-selectins, vascular and intercellular adhesion molecules (sVCAM-1, sICAM-1, pro/antiinflammatory cytokines [tumor necrosis factor (TNF-α and interleukin (IL-10], tissue factor (sTF, thrombomodulin (sTM and D-dimers (D-D were assessed by enzyme immunoassay. Twenty-five healthy subjects were studied as a control group. Results TBI provoked marked alterations in a majority of the inflammatory/coagulation markers assessed in all patients. Relative to control, NS patients showed up to a 2-fold higher surface expression of CD62L, CD11b and CD66b on polymorphonuclear neutrophils (PMNs and monocytes that persisted for 48-h. HSD blunted the expression of these cell-surface activation/adhesion molecules at all time-points to

    It is suggested that systemic oxidative stress and inflammation play a central role in the onset and progression of cardiovascular diseases associated with the exposure to particulate matter (PM). The aim of this work was to evaluate the time changes of systemic markers of oxidative stress and inflammation, after an acute exposure to Residual Oil Fly Ash (ROFA). Female Swiss mice were intranasally instilled with a ROFA suspension (1.0 mg/kg body weight) or saline solution, and plasma levels of oxidative damage markers [thiobarbituric acid reactive substances (TBARSs) and protein carbonyls], antioxidant status [reduced (GSH) and oxidized (GSSG) glutathione, ascorbic acid levels, and superoxide dismutase (SOD) activity], cytokines levels, and intravascular leukocyte activation were evaluated after 1, 3 or 5 h of exposure. Oxidative damage to lipids and decreased GSH/GSSG ratio were observed in ROFA-exposed mice as early as 1 h. Afterwards, increased protein oxidation, decreased ascorbic acid content and SOD activity were found in this group at 3 h. The onset of an adaptive response was observed at 5 h after the ROFA exposure, as indicated by decreased TBARS plasma content and increased SOD activity. The observed increase in oxidative damage to plasma macromolecules, together with systemic antioxidants depletion, may be a consequence of a systemic inflammatory response triggered by the ROFA exposure, since increased TNF-α and IL-6 plasma levels and polymorphonuclear leukocytes activation was found at every evaluated time point. These findings contribute to the understanding of the increase in cardiovascular morbidity and mortality, in association with environmental PM inhalation. - Highlights: • An acute exposure to ROFA triggers the occurrence of systemic oxidative stress. • Changes in plasmatic oxidative stress markers appear as early as 1 h after exposure. • ROFA induces proinflammatory cytokines release and intravascular leukocyte activation. • PMN

    Intra-amniotic inflammation with preterm premature rupture of membranes (PPROM) is a risk factor for fetal inflammatory response syndrome (FIRS) and adverse neonatal outcome. To evaluate the diagnostic accuracy of lipopolysaccharide-binding protein (LBP) for detecting FIRS in preterm neonates born after PPROM. This was a prospective study in the level III neonatal intensive care unit (42 neonates; 23 + 6 to 31 + 6 weeks' gestation) of mothers with PPROM. Umbilical cord blood concentrations of LBP, C-reactive protein (CRP), interleukin (IL)-6 and white blood cell count with differential were measured at delivery and 24 h after birth. Neonates were classified into FIRS (n = 22) and no FIRS (n = 20) groups according to clinical criteria and IL-6 level (≥17.5 pg/ml). Histological examination of the placenta and umbilical cord was performed. Neurological examination at 12 months' corrected age was performed. Umbilical cord blood concentration of LBP was significantly higher in the FIRS group than in the no FIRS group at delivery (median 21.6 mg/l vs. median 2.3 mg/l; p < 0.0001) and 24 h after birth (median 17.2 mg/l vs. median 20.0 mg/l; p < 0.001). The area under the ROC curve for FIRS at delivery was 0.98 (95% CI 0.88-1.0) for LBP, 0.92 (95% CI 0.80-0.99) for CRP and 0.82 (95% CI 0.64-0.94) for immature to total neutrophil ratio. Similar results were obtained if FIRS was defined by funisitis. Umbilical cord blood concentration of LBP at delivery was significantly higher in neonates with abnormal neurological exam at 12 months than in those with normal exam (median 19.5 mg/l vs. median 3.75 mg/l; p < 0.015). In preterm neonates born to asymptomatic women with PPROM, LBP in cord blood at delivery is an excellent diagnostic biomarker of FIRS/funisitis with prognostic potential. © 2013 S. Karger AG, Basel.

    We explored whether high blood pressure is associated with metabolic, inflammatory and prothrombotic dysregulation in patients with metabolic syndrome. We evaluated 135 consecutive overweight/obese patients. From this group, we selected 75 patients who were not under the regular use of medications for metabolic syndrome as defined by the current Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults criteria. The patients were divided into metabolic syndrome with and without high blood pressure criteria (≥130/≥85 mmHg). Compared to the 45 metabolic syndrome patients without high blood pressure, the 30 patients with metabolic syndrome and high blood pressure had significantly higher glucose, insulin, homeostasis model assessment insulin resistance index, total cholesterol, low-density lipoprotein-cholesterol, triglycerides, uric acid and creatinine values; in contrast, these patients had significantly lower high-density lipoprotein-cholesterol values. Metabolic syndrome patients with high blood pressure also had significantly higher levels of retinol-binding protein 4, plasminogen activator inhibitor 1, interleukin 6 and monocyte chemoattractant protein 1 and lower levels of adiponectin. Moreover, patients with metabolic syndrome and high blood pressure had increased surrogate markers of sympathetic activity and decreased baroreflex sensitivity. Logistic regression analysis showed that high-density lipoprotein, retinol-binding protein 4 and plasminogen activator inhibitor-1 levels were independently associated with metabolic syndrome patients with high blood pressure. There is a strong trend for an independent association between metabolic syndrome patients with high blood pressure and glucose levels. High blood pressure, which may be related to the autonomic dysfunction, is associated with metabolic, inflammatory and prothrombotic dysregulation in patients with metabolic syndrome.

    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 aim of this study was to evaluate the effectiveness of specific immunotherapy (SIT) management with allergoids in children with allergic asthma by monitoring changes in clinical parameters and inflammatory markers in exhaled breath. The study population included 43 patients (24 males) of 6-14 years of age, who had allergic asthma and were sensitized to mites. Twenty-three individuals were treated with subcutaneous SIT (PURETHAL® Mites, HAL Allergy) for 8 months, i.e. the SIT group, and 20 were given medication to treat symptoms only, i.e. the control group. Before treatment and after 4 and 8 months, several clinical parameters, the levels of exhaled nitric oxide and the pH of exhaled breath condensate (EBC) were determined. The SIT group presented with an improvement in asthma classification, a reduction in maintenance drug therapy and improved scores on the quality-of-life questionnaire. These changes were not observed in the control group. Both groups presented significant decreases in EBC pH values at 4 and 8 months after treatment compared to at baseline. However, analysis of the variable 'ratio' showed an increase in the EBC pH values after 8 months of treatment in the SIT group compared with the values at 4 months. SIT with standardized mite extract reduces asthma symptoms in children. A decrease in EBC pH values was observed in both groups, although the SIT group presented a tendency of recovered values after 8 months. Future studies of EBC pH monitoring in the longer term are needed to determine the effectiveness of this marker. © 2014 S. Karger AG, Basel.

    Comparison of Q fever fatigue syndrome (QFS) and chronic fatigue syndrome (CFS) patients, with a focus on markers of inflammation and fatigue-related cognitive-behavioural variables. Data from two independent prospective studies on QFS (n=117) and CFS (n=173), respectively, were pooled and analyzed. QFS patients were less often female, had a higher BMI, and had less often received treatment for depression before the onset of symptoms. After controlling for symptom duration and correcting for differences in diagnostic criteria for QFS and CFS with respect to the level of impairment and the presence of additional symptoms, differences in the proportion of females and BMI remained significant. After correction, QFS patients were also significantly older. In all analyses QFS patients were as fatigued and distressed as CFS patients, but reported less additional symptoms. QFS patients had stronger somatic attributions, and higher levels of physical activity. No differences were found with regard to inflammatory markers and in other fatigue-related cognitive-behavioural variables. The relationship between cognitive-behavioural variables and fatigue, previously established in CFS, could not be confirmed in QFS patients with the exception of the negative relationship between physical activity and fatigue. Differences and similarities between QFS and CFS patients were found. Although the relationship between perpetuating factors and fatigue previously established in CFS could not be confirmed in QFS patients, the considerable overlap in fatigue-related cognitive-behavioural variables and the relationship found between physical activity and fatigue may suggest that behavioural interventions could reduce fatigue severity in QFS patients.

    Full Text Available Objective: To study the relationship of plasma proadrenomedullin (pro-ADM and cortisol (Cor levels with systemic inflammatory response and target organ damage in children with sepsis after burn. Methods: A total of 30 children with sepsis after burn who were treated in the hospital between August 2014 and August 2016 were collected as observation group, and 30 normal children who received vaccination in the hospital during the same period were collected as normal control group. The pro-ADM and Cor levels in plasma as well as the levels of inflammatory factors, myocardial injury markers and intestinal barrier function indexes in serum of the two groups were determined. Pearson test was used to assess the correlation of plasma pro-ADM and Cor levels with systemic inflammatory response and target organ damage in patients with sepsis after burn. Results: Plasma pro-ADM and Cor levels in observation group were higher than those in normal control group. Serum inflammatory cytokines IL-1, IL-6, IL-10 and TNF-α levels in observation group were higher than those in normal control group; serum myocardial injury markers CK-MB, cTnⅠ and NT-proBNP levels were higher than those in normal control group; serum intestinal barrier function indexes ET, DAO and D-L levels were higher than those in normal control group. Conclusion: Plasma pro-ADM and Cor levels increase in patients with sepsis after burn, and are highly consistent with systemic inflammatory response and target organ injury.

    We designed studies to determine whether the ApoE-/- phenotype modulates the local skeletal muscle and systemic inflammatory (plasma) responses to lower extremity demand ischemia. The ApoE-/- phenotype is an experimental model for atherosclerosis in humans. Aged female ApoE-/- and C57BL6 mice underwent femoral artery ligation, then were divided into sedentary and demand ischemia (exercise) groups on day 14. We assessed baseline and postexercise limb perfusion and hind limb function. On day 14, animals in the demand ischemia group underwent daily treadmill exercise through day 28. Sedentary mice were not exercised. On day 28, we harvested plasma and skeletal muscle from ischemic limbs from sedentary and exercised mice. We assayed muscle for angiogenic and proinflammatory proteins, markers of skeletal muscle regeneration, and evidence of skeletal muscle fiber maturation. Hind limb ischemia was similar in ApoE-/- and C57 mice before the onset of exercise. Under sedentary conditions, plasma vascular endothelial cell growth factor and interleukin-6, but not keratinocyte chemoattractant factor (KC) or macrophage inflammatory protein-2 (MIP-2), were higher in ApoE (P factor, KC, and MIP-2, but not IL-6, were lower in ApoE (P demand ischemia in the C57BL6 mice, compared with the ApoE-/- mice (P = 0.01). Demand limb ischemia in the ApoE-/- phenotype exacerbated the expression of select systemic cytokines in plasma and blunted indices of muscle regeneration. Copyright © 2013 Elsevier Inc.

    The present study aimed to compare the utility of various inflammatory marker- and nutritional status-based prognostic factors, including many previous established prognostic factors, for predicting the prognosis of stage IV gastric cancer patients undergoing non-curative surgery. A total of 33 patients with stage IV gastric cancer who had undergone palliative gastrectomy and gastrojejunostomy were included in the study. Univariate and multivariate analyses were performed to evaluate the relationships between the mGPS, PNI, NLR, PLR, the CONUT, various clinicopathological factors and cancer-specific survival (CS). Among patients who received non-curative surgery, univariate analysis of CS identified the following significant risk factors: chemotherapy, mGPS and NLR, and multivariate analysis revealed that the mGPS was independently associated with CS. The mGPS was a more useful prognostic factor than the PNI, NLR, PLR and CONUT in patients undergoing non-curative surgery for stage IV gastric cancer.

    Chronic inflammation is a predisposing factor to numerous degenerative diseases including cancer, heart failure and Alzheimer's disease. Infla-Kine is a natural supplement comprised of a proprietary blend of Lactobacillus fermentum extract, burdock seed (arctigenin), zinc, alpha lipoic acid, papaya enzyme and an enhanced absorption bio-curcumin complex (BCM-95 ® ). Infla-Kine was administered twice daily to 24 health volunteers for 4 weeks. Quantitative RT-PCR was used to assess mRNA transcripts of IL-1b, IL8, IL-6, NF-κB, and TNF-α from peripheral blood mononuclear cells (PBMC). C reactive protein (CRP) was measured from serum. Additionally, quality of life questionnaires were employed to assess general feeling of well-being. Assessments were made before treatment and at conclusion of treatment (4 weeks). As compared to pre-treatment, after 4 weeks, a statistically significant reduction of IL8, IL-6, NF-κB, and TNF-α transcripts was observed in PBMC. Furthermore, reduction of IL-1b transcript and serum CRP was observed but did not reach statistical significance. Quality of life improvements were most prevalent in muscle and joint pains. Overall, our data demonstrate that twice daily administration of Infla-Kine for 4 weeks reduces inflammatory markers and quality of life in healthy volunteers.

    Full Text Available Introduction and objective. Swine confinement buildings are known to contain large concentrations of airway irritants, and a number of studies have shown acute inflammatory effects in previously unexposed subjects when introduced to the environment in such buildings. However, studies comparing different methods of assessing such reactions are lacking, and it is not known if a measurable response could be found at lower exposure rates. The purpose of this study was to investigate exposure levels in a Norwegian swine confinement building, the airway response to such exposure, and to compare invasive and non-invasive methods of response measurement. Materials and method. Twelve medical students who were previously unexposed to swine dust stayed in a swine confinement building in Norway for 4 hours, and underwent measurements before and after the start of exposure. The same measurements were also performed beforehand, on the same weekday without exposure, in such a manner that the subjects were their own controls. Results. The exposure assessment showed considerably lower concentrations of organic dust and endotoxin than earlier studies. However, small, but significant increases in markers of airway inflammation, were found. Conclusions. Airway response can be measured after lower exposure to airborne irritants in swine confinement buildings than previously known. Further research is needed to assess whether this finding can be utilized for preventive purposes.

    In order to apply augmented reality in plant maintenance activities it is necessary to use real-time high accuracy tracking technology. One of the most efficient tracking methods is using paper-based markers and computing the relative position and orientation between a vision sensor (camera) and the markers through image processing and geometry calculations. In this method, the 3D-position of each marker is needed before tracking, but it is inefficient to measure all the markers manually. In this study, an automatic marker registration system was developed so as to measure the 3D-position of each marker automatically. The system is composed of a camera, a laser rangefinder and a motion base, which is used to control the pose of the laser rangefinder. A computer, connected to them, is used for controlling the system and for data transport. The results of the experimental evaluations show that the measurement takes about 21 seconds per marker and that the Root Mean Square Error (RMSE) of the position measurements is 3.5 mm. The feasibility evaluation of the system was conducted in Fugen nuclear plant. The results show that the system can largely reduce the preparatory workload of an AR application in a Nuclear Power Plant (NPP). (author)

  4. MRA in inflammatory disorders of the central nervous system

    In this review, we discuss the diagnostic potential of time of flight (TOF) MRA and contrast enhanced (CE) MRA in inflammatory disorders of the meninges and the brain. Cerebrovascular complications are frequently observed during infectious meningoencepalitis. 3D TOF-MRA and CE-MRA are complementary for the detection of basal intracranial artery stenosis and septic cerebral vein and sinus thrombosis due to secondary vasculitis. MRA reveals stenosis and occlusion as indirect signs of vasculitis, whereas MRI shows the inflammation of the brain and meninges and occasionally the vessel wall, together with the ischemic or hemorrhagic complication. In case of septic emboli MRA can detect peripheral occlusions and 'mycotic' aneurysms. For the diagnosis of noninfectious vasculitides of the intracranial vessels, high resolution 3D TOF-MRA is superior to CE-MRA for the detection of multiloculated segmental stenoses. However, there are presently no prospective studies on the sensitivity and specificity of MRA for these indications. Therefore, only positive MRA results can directly influence clinical management. In case of normal MRA, confirmation by catheder angiography may still be required. (orig.) [de

  5. A selectable and excisable marker system for the rapid creation of recombinant poxviruses.

    Full Text Available Genetic manipulation of poxvirus genomes through attenuation, or insertion of therapeutic genes has led to a number of vector candidates for the treatment of a variety of human diseases. The development of recombinant poxviruses often involves the genomic insertion of a selectable marker for purification and selection purposes. The use of marker genes however inevitably results in a vector that contains unwanted genetic information of no therapeutic value.Here we describe an improved strategy that allows for the creation of marker-free recombinant poxviruses of any species. The Selectable and Excisable Marker (SEM system incorporates a unique fusion marker gene for the efficient selection of poxvirus recombinants and the Cre/loxP system to facilitate the subsequent removal of the marker. We have defined and characterized this new methodological tool by insertion of a foreign gene into vaccinia virus, with the subsequent removal of the selectable marker. We then analyzed the importance of loxP orientation during Cre recombination, and show that the SEM system can be used to introduce site-specific deletions or inversions into the viral genome. Finally, we demonstrate that the SEM strategy is amenable to other poxviruses, as demonstrated here with the creation of an ectromelia virus recombinant lacking the EVM002 gene.The system described here thus provides a faster, simpler and more efficient means to create clinic-ready recombinant poxviruses for therapeutic gene therapy applications.

    2011-06-01

    Full Text Available Abstract Background Functional aspects of mast cell-neuronal interactions remain poorly understood. Mast cell activation and degranulation can result in the release of powerful pro-inflammatory mediators such as histamine and cytokines. Cerebral dural mast cells have been proposed to modulate meningeal nociceptor activity and be involved in migraine pathophysiology. Little is known about the functional role of spinal cord dural mast cells. In this study, we examine their potential involvement in nociception and synaptic plasticity in superficial spinal dorsal horn. Changes of lower spinal cord dura mast cells and their contribution to hyperalgesia are examined in animal models of peripheral neurogenic and non-neurogenic inflammation. Results Spinal application of supernatant from activated cultured mast cells induces significant mechanical hyperalgesia and long-term potentiation (LTP at spinal synapses of C-fibers. Lumbar, thoracic and thalamic preparations are then examined for mast cell number and degranulation status after intraplantar capsaicin and carrageenan. Intradermal capsaicin induces a significant percent increase of lumbar dural mast cells at 3 hours post-administration. Peripheral carrageenan in female rats significantly increases mast cell density in the lumbar dura, but not in thoracic dura or thalamus. Intrathecal administration of the mast cell stabilizer sodium cromoglycate or the spleen tyrosine kinase (Syk inhibitor BAY-613606 reduce the increased percent degranulation and degranulated cell density of lumbar dural mast cells after capsaicin and carrageenan respectively, without affecting hyperalgesia. Conclusion The results suggest that lumbar dural mast cells may be sufficient but are not necessary for capsaicin or carrageenan-induced hyperalgesia.

    Periodontal disease is an inflammatory disease that has numerous consequences both locally and systemically The aim of this study was to assess whether periodontal disease causes systemic inflammatory response in otherwise healthy, adult dogs. We estimated the total mouth periodontal score (TMPS), measured the concentration of C-reactive protein (CRP), hematocrit, and albumin, and determined the white blood cell (WBC) and polymorphonuclear cell (PMN) counts in client-owned dogs. There was a statistically significant relationship between the gingival bleeding index (TMPS-G) and CRP concentration, and WBC and PMN counts, possibly during the active periods of periodontal tissue destruction. No correlation was found between the periodontal destruction index (TMPS-P) and the measured blood parameters. We conclude that chronic periodontal disease does not cause anemia or a reduction in serum albumin. However, active periods of periodontal inflammation may be associated with laboratory values suggestive of a systemic inflammatory response.

    The aim of this study was to investigate the effects of resistance exercise training (RET) on oxidative stress, systemic inflammatory markers, and muscle wasting in Walker-256 tumor-bearing rats. Male (Wistar) rats were divided into 4 groups: sedentary controls (n = 9), tumor-bearing (n = 9), exercised (n = 9), and tumor-bearing exercised (n = 10). Exercised and tumor-bearing exercised rats were exposed to resistance exercise of climbing a ladder apparatus with weights tied to their tails for 6 weeks. The physical activity of control and tumor-bearing rats was confined to the space of the cage. After this period, tumor-bearing and tumor-bearing exercised animals were inoculated subcutaneously with Walker-256 tumor cells (11.0 × 10 7 cells in 0.5 mL of phosphate-buffered saline) while control and exercised rats were injected with vehicle. Following inoculation, rats maintained resistance exercise training (exercised and tumor-bearing exercised) or sedentary behavior (control and tumor-bearing) for 12 more days, after which they were euthanized. Results showed muscle wasting in the tumor-bearing group, with body weight loss, increased systemic leukocytes, and inflammatory interleukins as well as muscular oxidative stress and reduced mTOR signaling. In contrast, RET in the tumor-bearing exercised group was able to mitigate the reduced body weight and muscle wasting with the attenuation of muscle oxidative stress and systemic inflammatory markers. RET also prevented loss of muscle strength associated with tumor development. RET, however, did not prevent the muscle proteolysis signaling via FBXO32 gene messenger RNA expression in the tumor-bearing group. In conclusion, RET performed prior tumor implantation prevents cachexia development by attenuating tumor-induced systemic pro-inflammatory condition with muscle oxidative stress and muscle damage.

    Based on earlier literature, etoricoxib may have a delayed analgesic effect in postoperative setting when analgesic efficacy of nonselective nonsteroidal anti-inflammatory drug dexketoprofen is rapid. This may be caused by slow penetration of etoricoxib into the central nervous system (CNS). Therefore we decided to determine the plasma and cerebrospinal fluid (CSF) pharmacokinetics and pharmacodynamics of dexketoprofen and etoricoxib in patients with hip arthroplasty. A total of 24 patients, scheduled for an elective primary hip arthroplasty were enrolled. After surgery, 12 subjects were randomized to received a single intravenous dose of dexketoprofen, and 12 subjects were given oral etoricoxib. Paired blood and CSF samples were taken up to 24 h for measurement of drug concentrations, interleukin (IL)-6, IL-1ra and blood for interleukin 10. In CSF the highest measured concentration (C max) of dexketoprofen was 4.0 (median) ng/mL (minimum-maximum 1.9-13.9) and time to the highest concentration (t max) 3 h (2-5), and for etoricoxib C max 73 ng/mL (36-127) and t max 5 h (1-24), respectively. Opioid consumption during the first 24 postoperative hours was similar in the two groups. Dexketoprofen and etoricoxib had a similar effect on the postoperative inflammatory response. No significant differences considering pain relief or adverse events were found between the two groups. Dexketoprofen and etoricoxib entered the CNS readily, already at 30 min after administration dexketoprofen was detected in the CSF in most subjects and etoricoxib after 60 min. A single dose of dexketoprofen and etoricoxib provided a similar anti-inflammatory and analgesic response after major orthopaedic surgery.

    The major goals of this study were to define the relationships between intrapulmonary and systemic inflammatory responses in animals with gram-negative pneumonia. We treated rabbits with intrapulmonary Escherichia coli (1 x 10(7) to 1 x 10(10) cfu/ml), and then measured physiologic, cellular, and molecular events in the lungs and systemic circulation for 24 h. The treatment protocols resulted in groups of animals that mimicked the stages of the septic inflammatory response in humans. Animals treated with low inocula had systemic changes consistent with systemic inflammatory response syndrome and cleared the bacteria and inflammatory products from the lungs. Animals treated with high inocula failed to clear bacteria from the lungs, had severe intrapulmonary inflammatory responses, and developed septic shock. Intrapulmonary leukocyte recruitment was directly related to the size of the bacterial inoculum, but lung protein accumulation was not. Tumor neurosis factor-alpha (TNF-alpha), interleukin-8 (IL-8), and GRO were detectable in lung lavage fluid at 4 h and declined by 24 h in animals that cleared intrapulmonary E. coli. In contrast, lavage TNF-alpha, IL-8, and GRO increased over 24 h in animals that failed to clear intrapulmonary bacteria. MCP-1 increased between 4 h and 24 h in the lungs of all of the animals as the histologic response evolved from neutrophilic to mononuclear cell predominance. Thus, the intensity of systemic inflammatory and physiologic responses to intrapulmonary gram-negative infection depends on the inoculum size and whether the bacteria are cleared from or proliferate in the lungs. The results provide experimental support for the recently proposed classification of septic responses in humans.

    We have proposed a magnetic motion capture system using an LC resonant magnetic marker. The proposed system is composed of an exciting coil, an LC marker, and a 5x5-matrix search coil array (25 search coils). The LC marker is small and has a minimal circuit with no battery and can be driven wirelessly by the action of electromagnetic induction. It consists of a Ni-Zn ferrite core (3 mmφx10 mm) with a wound coil and a chip capacitor, forming an LC series circuit with a resonant frequency of 186 kHz. The relative position accuracy of the system is less than 1 mm within the area of 100 mm 3 up to 150 mm from the search coil array. Compared with dc magnetic systems, the proposed system is applicable for precision motion capture in optically isolated spaces without magnetic shielding because the system is not greatly influenced by earth field noise

    Studies in humans with overweight or obesity have reported that some prebiotics and synbiotics have beneficial effects on metabolic endotoxaemia and immune function. However, to date, no systematic review of controlled clinical trials assessed this topic. The aim of this study was to evaluate the effects of inulin-type fructans, galacto-oligosaccharides and related synbiotics on inflammatory markers in adults with overweight or obesity. A systematic review of the literature was performed until November 6, 2015 in four electronic databases and reference lists of all included articles and relevant reviews in the field, without using any filter. Ten trials (six prebiotic and four synbiotic trials) representing 534 overweight/obese adults were included. All trials evaluated C-reactive protein or high-sensitivity C-reactive protein, four trials evaluated cytokines (two prebiotic and two synbiotic trials) and five trials evaluated endotoxin (four prebiotic and one synbiotic trials). Six trials (two with galacto-oligosaccharide, one with inulin and three with different synbiotics) showed a reduction on high-sensitivity C-reactive protein. Four trials (one with oligofructose-enriched inulin, one with inulin and two with different synbiotics) showed a reduction on interleukin-6 and/or tumor necrosis factor. Four trials (one with galacto-oligosaccharide, one with oligofructose-enriched inulin, one with inulin and one with synbiotic) showed a reduction on endotoxin. Some prebiotics and synbiotics may have immunomodulatory action, however, more randomized controlled trials are needed to support the clinical use of inulin-type fructans, galacto-oligosaccharides or related synbiotics for the treatment of metabolic endotoxaemia or low-grade inflammation in overweight/obese people.

    Full Text Available AbstractINTRODUCTION: Liposuction is a surgical procedure effective in reducing body fat, withgrowing application in conjunction with diet and exercise therapy in the treatment of obesity.In view of the positive effect of weight reduction on cardiovascular disease (CVD riskfactors, such as body mass index (BMI, waist circumference (WC, waist-to-hip ratio(WHR, systolic and diastolic pressure, lipid profile, fasting blood sugar, insulin resistance,inflammatory markers (e.g. chronic reactive protein: CRP, antioxidant capacity, fibrinogenand lipoprotein A (Lpa, this study was conducted to assess the effect of liposuction as atherapeutic procedure in the treatment of obesity.METHODS: A total of 24 non-diabetic obese women (BMI>30 with a mean age of48.7±7.3 years were studied. Before liposuction, the subjects filled out questionnairesobtaining demographic information. Complete physical examination, measurement of waistand hip circumference, height, weight and calculation of WHR and BMI were performed.Fasting blood samples were taken to measure fasting blood glucose, total cholesterol, highdensitylipoprotein (HDL, low-density lipoprotein (LDL, triglyceride (TG, fibrinogen,antioxidant capacity, CRP, lipoprotein A, serum insulin, and insulin resistance. Allmeasurements and physical examinations were repeated 12-14 weeks after liposuction.Data were analyzed with SPSS11 software using paired t-test and repeated measureANOVA.RESULTS: WHR, BMI and LDL decreased significantly following liposuction (P<0.05.Other parameters, however, did not change significantly, although there were signs ofpositive changes.DISCUSSION: Liposuction decreases BMI, WHR and LDL within 12-14 weeks ofliposuction. Providing these reductions are maintained, liposuction may prove valuable inreducing CVD risk factors, besides offering a means for obesity control.Keywords • Liposuction • Obesity

  17. A multi-centre cohort study evaluating the role of inflammatory markers in patient’s presenting with acute ureteric colic (MIMIC

    T.T. Shah

    Full Text Available Background: Spontaneous Stone Passage (SSP rates in acute ureteric colic range from 47 to 75%. There is conflicting evidence on the role of raised inflammatory markers in acute ureteric colic. The use of an easily applicable biomarker that could predict SSP or need for intervention would improve the management of obstructing ureteric stones. Thus, there is a need to determine in an appropriately powered study, in patients who are initially managed conservatively, which factors at the time of acute admission can predict subsequent patient outcome such as SSP and the need for intervention. Particularly, establishing whether levels of white cell count (WBC at presentation are associated with likelihood of SSP or intervention may guide clinicians on the management of these patients’ stones. Design: Multi-center cohort study disseminated via the UK British Urology Researchers in Surgical Training (BURST and Australian Young Urology Researchers Organisation (YURO. Primary research question: What is the association between WBC and SSP in patients discharged from emergency department after initial conservative management? Patient population: Patients who have presented with acute renal colic with CT KUB evidence of a solitary ureteric stone. A minimum sample size of 720 patients across 15 centres will be needed. Hypothesis: A raised WBC is associated with decreased odds of spontaneous stone passage. Primary outcome: The occurrence of SSP within six months of presentation with acute ureteric colic (YES/NO. SSP was defined as absence of need for intervention to assist stone passage. Statistical analysis plan: A multivariable logistic regression model will be constructed, where the outcome of interest is SSP using data from patients who do not undergo intervention at presentation. A random effect will be used to account for clustering of patients within hospitals/institutions. The model will include adjustments for gender, age as control variables

    Plasma lipids have been extensively studied in sedentary and in subjects practicing exercise training, but not in extreme inactivity as occurs in bedridden patients. This is important for the care of bedridden patients and understanding the overall plasma lipid regulation. Here, we investigated plasma lipids, lipid transfers to HDL and inflammatory markers in bedridden patients. Fasting blood samples were collected from 23 clinically stable bedridden patients under long-term care (>90 days) and 26 normolipidemic sedentary subjects, paired for age and gender. In vitro transfer of four lipids to HDL was performed by incubating plasma with donor nanoparticles containing radioactive lipids. Total (193 ± 36 vs 160 ± 43, p = 0.005), LDL (124 ± 3 vs 96 ± 33 p = 0.003) and HDL-cholesterol (45 ± 10 vs 36 ± 13, p = 0.008), apolipoprotein A-I (134 ± 20 vs 111 ± 24, p = 0.001) and oxidized LDL (53 ± 13 vs 43 ± 12, p = 0.011) were lower in bedridden patients, whereas triglycerides, apolipoprotein B, CETP and LCAT were equal in both groups. Transfers of all lipids, namely unesterified cholesterol, cholesterol esters, triglycerides and phospholipids, to HDL were lower in bedridden patients, probably due to their lower HDL-cholesterol levels. Concentrations of IL-1β, IL-6, IL-8, HGF and NGF were higher in bedridden patients compared to sedentary subjects. In conclusion, inactivity had great impact on HDL, by lowering HDL-cholesterol, apolipoprotein A-I and thereby cholesterol transfers to the lipoprotein, which suggests that inactivity may deteriorate HDL protection beyond the ordinary sedentary condition.

    Context: Hesperidin, a citrus flavonoid, and its metabolite hesperetin may have vascular actions relevant to their health benefits. Molecular and physiological mechanisms of hesperetin actions are unknown. Objective: We tested whether hesperetin stimulates production of nitric oxide (NO) from vascular endothelium and evaluated endothelial function in subjects with metabolic syndrome on oral hesperidin therapy. Design, Setting, and Interventions: Cellular mechanisms of action of hesperetin were evaluated in bovine aortic endothelial cells (BAEC) in primary culture. A randomized, placebo-controlled, double-blind, crossover trial examined whether oral hesperidin administration (500 mg once daily for 3 wk) improves endothelial function in individuals with metabolic syndrome (n = 24). Main Outcome Measure: We measured the difference in brachial artery flow-mediated dilation between placebo and hesperidin treatment periods. Results: Treatment of BAEC with hesperetin acutely stimulated phosphorylation of Src, Akt, AMP kinase, and endothelial NO synthase to produce NO; this required generation of H2O2. Increased adhesion of monocytes to BAEC and expression of vascular cell adhesion molecule-1 in response to TNF-α treatment was reduced by pretreatment with hesperetin. In the clinical study, when compared with placebo, hesperidin treatment increased flow-mediated dilation (10.26 ± 1.19 vs. 7.78 ± 0.76%; P = 0.02) and reduced concentrations of circulating inflammatory biomarkers (high-sensitivity C-reactive protein, serum amyloid A protein, soluble E-selectin). Conclusions: Novel mechanisms for hesperetin action in endothelial cells inform effects of oral hesperidin treatment to improve endothelial dysfunction and reduce circulating markers of inflammation in our exploratory clinical trial. Hesperetin has vasculoprotective actions that may explain beneficial cardiovascular effects of citrus consumption. PMID:21346065

    A novel multi-sensor fusion indoor localization algorithm based on ArUco marker is designed in this paper. The proposed ArUco mapping algorithm can build and correct the map of markers online with Grubbs criterion and K-mean clustering, which avoids the map distortion due to lack of correction. Based on the conception of multi-sensor information fusion, the federated Kalman filter is utilized to synthesize the multi-source information from markers, optical flow, ultrasonic and the inertial sensor, which can obtain a continuous localization result and effectively reduce the position drift due to the long-term loss of markers in pure marker localization. The proposed algorithm can be easily implemented in a hardware of one Raspberry Pi Zero and two STM32 micro controllers produced by STMicroelectronics (Geneva, Switzerland). Thus, a small-size and low-cost marker-based localization system is presented. The experimental results show that the speed estimation result of the proposed system is better than Px4flow, and it has the centimeter accuracy of mapping and positioning. The presented system not only gives satisfying localization precision, but also has the potential to expand other sensors (such as visual odometry, ultra wideband (UWB) beacon and lidar) to further improve the localization performance. The proposed system can be reliably employed in Micro Aerial Vehicle (MAV) visual localization and robotics control.

    Next-generation sequencing methods have initiated a revolution in molecular ecology and evolution (Tautz et al. ). Among the most impressive of these sequencing innovations is restriction site-associated DNA sequencing or RAD-seq (Baird et al. ; Andrews et al. ). RAD-seq uses the Illumina sequencing platform to sequence fragments of DNA cut by a specific restriction enzyme and can generate tens of thousands of molecular genetic markers for analysis. One of the many uses of RAD-seq data has been to identify sex-specific genetic markers, markers found in one sex but not the other (Baxter et al. ; Gamble & Zarkower ). Sex-specific markers are a powerful tool for biologists. At their most basic, they can be used to identify the sex of an individual via PCR. This is useful in cases where a species lacks obvious sexual dimorphism at some or all life history stages. For example, such tests have been important for studying sex differences in life history (Sheldon ; Mossman & Waser ), the management and breeding of endangered species (Taberlet et al. ; Griffiths & Tiwari ; Robertson et al. ) and sexing embryonic material (Hacker et al. ; Smith et al. ). Furthermore, sex-specific markers allow recognition of the sex chromosome system in cases where standard cytogenetic methods fail (Charlesworth & Mank ; Gamble & Zarkower ). Thus, species with male-specific markers have male heterogamety (XY) while species with female-specific markers have female heterogamety (ZW). In this issue, Fowler & Buonaccorsi () illustrate the ease by which RAD-seq data can generate sex-specific genetic markers in rockfish (Sebastes). Moreover, by examining RAD-seq data from two closely related rockfish species, Sebastes chrysomelas and Sebastes carnatus (Fig. ), Fowler & Buonaccorsi () uncover shared sex-specific markers and a conserved sex chromosome system. © 2016 John Wiley & Sons Ltd.

    This study aimed to examine the impact of combined supplementation of fish oil (FO) with antioxidants like wheat germ oil (WGO) on mineral-bone and inflammatory markers in maintenance HD patients. This randomized, double-blind, placebo-controlled trial involved 46 HD patients who were randomly assigned into two groups to receive daily 3000 mg of FO [1053 mg omega-3 fatty acids (ω-3 FAs)] plus 300 mg of WGO [0.765 mg vitamin E] or placebo for 4 months. Blood concentrations of hemoglobin (Hgb), white blood cells, mineral-bone parameters including serum calcium (Ca), phosphorus, calcium-phosphorus product, parathyroid hormone, alkaline phosphatase, and osteoprotegerin and serum concentrations of inflammatory markers including high-sensitivity C-reactive protein, ferritin, and uric acid were measured before and after the intervention. Eighty-seven percentage of patients in each group completed the study. The mean serum Ca levels increased significantly in the supplemented group at the end of study (p = 0.0016), and this increment was also significant as compared to placebo group (p = 0.0418). No significant alterations were observed in the other measured parameters within each group during the study (as p values were >0.05). FO plus WGO supplementation showed beneficial effect on serum Ca levels of HD patients without any statistically significant effect on other mineral-bone and inflammatory markers. Further investigations are required to confirm it.

    Babassu oil extraction is the main income source in nut breakers communities in northeast of Brazil. Among these communities, babassu oil is used for cooking but also medically to treat skin wounds and inflammation, and vulvovaginitis. This study aimed to evaluate the anti-inflammatory activity of babassu oil and develop a microemulsion system with babassu oil for topical delivery. Topical anti-inflammatory activity was evaluated in mice ear edema using PMA, arachidonic acid, ethyl phenylpropiolate, phenol, and capsaicin as phlogistic agents. A microemulsion system was successfully developed using a Span® 80/Kolliphor® EL ratio of 6 : 4 as the surfactant system (S), propylene glycol and water (3 : 1) as the aqueous phase (A), and babassu oil as the oil phase (O), and analyzed through conductivity, SAXS, DSC, TEM, and rheological assays. Babassu oil and lauric acid showed anti-inflammatory activity in mice ear edema, through inhibition of eicosanoid pathway and bioactive amines. The developed formulation (39% A, 12.2% O, and 48.8% S) was classified as a bicontinuous to o/w transition microemulsion that showed a Newtonian profile. The topical anti-inflammatory activity of microemulsified babassu oil was markedly increased. A new delivery system of babassu microemulsion droplet clusters was designed to enhance the therapeutic efficacy of vegetable oil. PMID:29430254

    Candida albicans is a commensal fungus that can cause systemic disease in patients with breaches in mucosal integrity, indwelling catheters, and defects in phagocyte function. Although circulating human and murine monocytes bind C. albicans and promote inflammation, it remains unclear whether C-C chemokine receptor 2 (CCR2)– and Ly6C-expressing inflammatory monocytes exert a protective or a deleterious function during systemic infection. During murine systemic candidiasis, interruption of CCR2-dependent inflammatory monocyte trafficking into infected kidneys impaired fungal clearance and decreased murine survival. Depletion of CCR2-expressing cells led to uncontrolled fungal growth in the kidneys and brain and demonstrated an essential antifungal role for inflammatory monocytes and their tissue-resident derivatives in the first 48 hours postinfection. Adoptive transfer of purified inflammatory monocytes in depleted hosts reversed the defect in fungal clearance to a substantial extent, indicating a compartmentally and temporally restricted protective function that can be transferred to enhance systemic innate antifungal immunity.

    Cardiac inflammatory disorders, either primarily cardiac or secondary to a systemic process, are associated with significant morbidity and/or mortality. Their diagnosis can be challenging, especially due to significant overlap in their clinical presentation with other cardiac diseases. Recent publications have investigated the potential diagnostic role of positron emission tomography (PET) imaging in these patients. Most of the available literature is focused on Fluorine-18 fluorodeoxyglucose (FDG), a tracer which has already demonstrated its use in other inflammatory and infectious processes. PET imaging can help in the diagnosis, prognosis and follow-up in a variety of cardiac inflammatory processes, including infective endocarditis, cardiac implantable electronic device infection, pericarditis, myocarditis, sarcoidosis and amyloidosis. PET’s ability to depict metabolic changes and abnormalities, sometime even before the onset of any anatomical changes, can be a significant advantage over standard anatomical imaging. PET appears to be particularly useful in cases where standard investigation is non-diagnostic or equivocal.

  10. The mast cell integrates the splanchnic and systemic inflammatory response in portal hypertension

    Full Text Available Abstract Portal hypertension is a clinical syndrome that is difficult to study in an isolated manner since it is always associated with a greater or lesser degree of liver functional impairment. The aim of this review is to integrate the complications related to chronic liver disease by using both, the array of mast cell functions and mediators, since they possibly are involved in the pathophysiological mechanisms of these complications. The portal vein ligated rat is the experimental model most widely used to study this syndrome and it has been considered that a systemic inflammatory response is produced. This response is mediated among other inflammatory cells by mast cells and it evolves in three linked pathological functional systems. The nervous functional system presents ischemia-reperfusion and edema (oxidative stress and would be responsible for hyperdynamic circulation; the immune functional system causes tissue infiltration by inflammatory cells, particularly mast cells and bacteria (enzymatic stress and the endocrine functional system presents endothelial proliferation (antioxidative and antienzymatic stress and angiogenesis. Mast cells could develop a key role in the expression of these three phenotypes because their mediators have the ability to produce all the aforementioned alterations, both at the splanchnic level (portal hypertensive enteropathy, mesenteric adenitis, liver steatosis and the systemic level (portal hypertensive encephalopathy. This hypothetical splanchnic and systemic inflammatory response would be aggravated during the progression of the chronic liver disease, since the antioxidant ability of the body decreases. Thus, a critical state is produced, in which the appearance of noxious factors would favor the development of a dedifferentiation process protagonized by the nervous functional system. This system rapidly induces an ischemia-reperfusion phenotype with hydration and salinization of the body (hepatorenal

    Due to a variety of factors to affect the herb quality, the existing quality management model is unable to evaluate the process control. The development of the concept of "quality marker" (Q-marker) lays basis for establishing an independent process quality control system for herbal products. To ensure the highest degree of safety, effectiveness and quality process control of herbal products, it is aimed to establish a quality transitivity and traceability system of quality and process control from raw materials to finished herbal products. Based on the key issues and challenges of quality assessment, the current status of quality and process controls from raw materials to herbal medicinal products listed in Pharmacopoeia were analyzed and the research models including discovery and identification of Q-markers, analysis and quality management of risk evaluation were designed. Authors introduced a few new technologies and methodologies, such as DNA barcoding, chromatographic technologies, fingerprint analysis, chemical markers, bio-responses, risk management and solution for quality process control. The quality and process control models for herbal medicinal products were proposed and the transitivity and traceability system from raw materials to the finished products was constructed to improve the herbal quality from the entire supply and production chain. The transitivity and traceability system has been established based on quality markers, especially on how to control the production process under Good Engineering Practices, as well as to implement the risk management for quality and process control in herbal medicine production.

Various inflammation biomarkers have been used in clinical and experimental practice. However, a definitive diagnostic tool for an early detection of systemic inflammation remains to be identified. Acetylcholine (Ach has been shown to play an important role in the inflammatory response. Serum cholinesterase (butyrylcholinesterase [BChE] is the major Ach hydrolyzing enzyme in blood. The role of this enzyme during inflammation has not yet been fully understood. This study tests whether a reduction in the BChE activity could indicate the onset of the systemic inflammatory response upon traumatic injury. Patients and methods: This observational study measured BChE activity in patients with traumatic injury admitted to the emergency room by using point-of-care-test system (POCT. In addition, the levels of routine inflammation biomarkers during the initial treatment period were measured. Injury Severity Score was used to assess the trauma severity. Results: Altered BChE activity was correlated with trauma severity, resulting in systemic inflammation. Reduction in the BChE activity was detected significantly earlier compared to those of routinely measured inflammatory biomarkers. Conclusion: This study suggests that the BChE activity reduction might serve as an early indicator of acute systemic inflammation. Furthermore, BChE activity, measured using a POCT system, might play an important role in the early diagnosis of the trauma-induced systemic inflammation.

    To review the usefulness of local and systemic inflammatory biomarkers of diabetic retinopathy (DR) to implement a more personalized treatment. An integrated research (from ophthalmologist and diabetologist point of view) of most significant literature on serum, vitreous, and aqueous humor (AH) biochemical biomarkers related to inflammation at early and advanced stages of DR (including diabetic macular edema [DME] and proliferative DR) was performed. Moreover, novel imaging retinal biomarkers of local "inflammatory condition" were described. Multiple inflammatory cytokines and chemokines are increased in DR in both serum as well as in the eye (vitreous and AH). Nevertheless, local rather than systemic production of proinflammatory cytokines seems more relevant in the pathogenesis of both DR and DME. In the eye, retinal glia cells (macroglia and microglia) together with RPE are major sources of proinflammatory and angiogenic modulators. Retinal imaging allows for noninvasive clinical evaluation of retinal inflammatory response induced by diabetes mellitus. Proinflammatory cytokines/chemokines play an essential role in the pathogenesis of DR. Therefore, circulating biomarkers and retinal imaging aimed at assessing inflammation have emerged as useful tools for monitoring the onset and progression of DR. In addition, "liquid biopsy" of AH seems a good option in patients with advanced stages of DR requiring intravitreous injections. This strategy may permit us to implement a more personalized treatment with better visual function outcome. Further evaluation and validation of circulating and local biomarkers, as well as multimodal imaging is needed to gain new insights into this issue.

    Dietary fat type is known to modulate the plasma lipid profile, but its effects on plasma homocysteine and inflammatory markers are unclear. We investigated the effects of high-protein Malaysian diets prepared with palm olein, coconut oil (CO), or virgin olive oil on plasma homocysteine and selected markers of inflammation and cardiovascular disease (CVD) in healthy adults. A randomized-crossover intervention with 3 dietary sequences of 5 wk each was conducted in 45 healthy subjects. The 3 test fats, namely palmitic acid (16:0)-rich palm olein (PO), lauric and myristic acid (12:0 + 14:0)-rich CO, and oleic acid (18:1)-rich virgin olive oil (OO), were incorporated at two-thirds of 30% fat calories into high-protein Malaysian diets. No significant differences were observed in the effects of the 3 diets on plasma total homocysteine (tHcy) and the inflammatory markers TNF-α, IL-1β, IL-6, and IL-8, high-sensitivity C-reactive protein, and interferon-γ. Diets prepared with PO and OO had comparable nonhypercholesterolemic effects; the postprandial total cholesterol for both diets and all fasting lipid indexes for the OO diet were significantly lower (P diet. Unlike the PO and OO diets, the CO diet was shown to decrease postprandial lipoprotein(a). Diets that were rich in saturated fatty acids prepared with either PO or CO, and an OO diet that was high in oleic acid, did not alter postprandial or fasting plasma concentrations of tHcy and selected inflammatory markers. This trial was registered at clinicaltrials.gov as NCT00941837.

    Tree peony (Paeonia suffruticosa Andrews), a woody deciduous shrub, belongs to the section Moutan DC. in the genus of Paeonia of the Paeoniaceae family. To increase the efficiency of breeding, two EST-derived marker systems were developed based on a tree peony expressed sequence tag (EST) database. Using target region amplification polymorphism (TRAP), 19 of 39 primer pairs showed good amplification for 56 accessions with amplicons ranging from 120 to 3,000 bp long, among which 99.3% were polymorphic. In contrast, 7 of 21 primer pairs demonstrated adequate amplification with clear bands for simple sequence repeats (SSRs) developed from ESTs, and a total of 33 alleles were found in 56 accessions. The similarity matrices generated by TRAP and EST-SSR markers were compared, and the Mantel test (r = 0.57778, P = 0.0020) showed a moderate correlation between the two types of molecular markers. TRAP markers were suitable for DNA fingerprinting and EST-SSR markers were more appropriate for discriminating synonyms (the same cultivars with different names due to limited information exchanged among different geographic areas). The two sets of EST-derived markers will be used further for genetic linkage map construction and quantitative trait locus detection in tree peony.

    The excessive release of cytokines by the immune system contributes importantly to the pathogenesis of inflammatory diseases. Recent advances in understanding the biology of cytokine toxicity led to the discovery of the “cholinergic anti-inflammatory pathway,” defined as neural signals transmitted via the vagus nerve that inhibit cytokine release through a mechanism that requires the alpha7 subunit-containing nicotinic acetylcholine receptor (α7nAChR). Vagus nerve regulation of peripheral functions is controlled by brain nuclei and neural networks, but despite considerable importance, little is known about the molecular basis for central regulation of the vagus nerve-based cholinergic anti-inflammatory pathway. Here we report that brain acetylcholinesterase activity controls systemic and organ specific TNF production during endotoxemia. Peripheral administration of the acetylcholinesterase inhibitor galantamine significantly reduced serum TNF levels through vagus nerve signaling, and protected against lethality during murine endotoxemia. Administration of a centrally-acting muscarinic receptor antagonist abolished the suppression of TNF by galantamine, indicating that suppressing acetylcholinesterase activity, coupled with central muscarinic receptors, controls peripheral cytokine responses. Administration of galantamine to α7nAChR knockout mice failed to suppress TNF levels, indicating that the α7nAChR-mediated cholinergic anti-inflammatory pathway is required for the anti-inflammatory effect of galantamine. These findings show that inhibition of brain acetylcholinesterase suppresses systemic inflammation through a central muscarinic receptor-mediated and vagal- and α7nAChR-dependent mechanism. Our data also indicate that a clinically used centrally-acting acetylcholinesterase inhibitor can be utilized to suppress abnormal inflammation to therapeutic advantage. PMID:18639629

    Full Text Available Abstract Bacterial genome is characterized by frequent unmethylated cytosine-phosphate-guanine (CpG motifs. Deleterious effects can occur when synthetic oligodeoxynucleotides (ODN with unmethylated CpG dinucleotides (CpG-ODN are administered in a systemic fashion. We aimed to evaluate the effect of intratracheal CpG-ODN on lung inflammation and systemic inflammatory response. C57BL/6J mice received intratracheal administration of CpG-ODN (0.01, 0.1, 1.0, 10, or 100 μM or control ODN without CpG motif. Bronchoalveolar lavage (BAL fluid was obtained 3 or 6 h or 1, 2, 7, or 14 days after the instillation and subjected to a differential cell count and cytokine measurement. Lung permeability was evaluated as the BAL fluid-to-plasma ratio of the concentration of human serum albumin that was injected 1 h before euthanasia. Nuclear factor (NF-κB DNA binding activity was also evaluated in lung homogenates. Intratracheal administration of 10 μM or higher concentration of CpG-ODN induced significant inflammatory cell accumulation into the airspace. The peak accumulation of neutrophils and lymphocytes occurred 1 and 2 days after the CpG-ODN administration, respectively. Lung permeability was increased 1 day after the 10 μM CpG-ODN challenge. CpG-ODN also induced nuclear translocation of NF-κB and upregulation of various inflammatory cytokines in BAL fluid and plasma. Histopathology of the lungs and liver revealed acute lung injury and liver damage with necrosis, respectively. Control ODN without CpG motif did not induce any inflammatory change. Since intratracheal CpG-ODN induced acute lung injury as well as systemic inflammatory response, therapeutic strategies to neutralize bacterial DNA that is released after administration of bactericidal agents should be considered.

    The paper deals with the comparison between a high-end marker-based acquisition system and a low-cost marker-less methodology for the assessment of the human posture during working tasks. The low-cost methodology is based on the use of a single Microsoft Kinect V1 device. The high-end acquisition system is the BTS SMART that requires the use of reflective markers to be placed on the subject's body. Three practical working activities involving object lifting and displacement have been investigated. The operational risk has been evaluated according to the lifting equation proposed by the American National Institute for Occupational Safety and Health. The results of the study show that the risk multipliers computed from the two acquisition methodologies are very close for all the analysed activities. In agreement to this outcome, the marker-less methodology based on the Microsoft Kinect V1 device seems very promising to promote the dissemination of computer-aided assessment of ergonomics while maintaining good accuracy and affordable costs. PRACTITIONER’S SUMMARY: The study is motivated by the increasing interest for on-site working ergonomics assessment. We compared a low-cost marker-less methodology with a high-end marker-based system. We tested them on three different working tasks, assessing the working risk of lifting loads. The two methodologies showed comparable precision in all the investigations.

    Posterior urethral valve is the most common lower urinary tract obstruction in male children. A high percentage of patients with posterior urethral valve evolve to end-stage renal disease. Previous studies showed that cytokines, chemokines, and components of the renin-angiotensin system contribute to the renal damage in obstructive uropathies. The authors recently found that urine samples from fetuses with posterior urethral valve have increased levels of inflammatory molecules. The aim of this study was to measure renin-angiotensin system molecules and to investigate their correlation with previously detected inflammatory markers in the same urine samples of fetuses with posterior urethral valve. Urine samples from 24 fetuses with posterior urethral valve were collected and compared to those from 22 healthy male newborns at the same gestational age (controls). Renin-angiotensin system components levels were measured by enzyme-linked immunosorbent assay. Fetuses with posterior urethral valve presented increased urinary levels of angiotensin (Ang) I, Ang-(1-7) and angiotensin-converting enzyme 2 in comparison with controls. ACE levels were significantly reduced and Ang II levels were similar in fetuses with posterior urethral valve in comparison with controls. Increased urinary levels of angiotensin-converting enzyme 2 and of Ang-(1-7) in fetuses with posterior urethral valve could represent a regulatory response to the intense inflammatory process triggered by posterior urethral valve.

    The aging process is the major driver of morbidity and mortality, steeply increasing the risk to succumb to cancer, cardiovascular disease, infection and neurodegeneration. Inflammation is a common denominator in age-related pathologies, identifying the immune system as a gatekeeper in aging overall. Among immune cells, T cells are long-lived and exposed to intense replication pressure, making them sensitive to aging-related abnormalities. In successful T cell aging, numbers of naïve cells, repertoire diversity and activation thresholds are preserved as long as possible; in maladaptive T cell aging, protective T cell functions decline and pro-inflammatory effector cells are enriched. Here, we review in the model system of rheumatoid arthritis (RA) how maladaptive T cell aging renders the host susceptible to chronic, tissue-damaging inflammation. In T cells from RA patients, known to be about 20years pre-aged, three interconnected functional domains are altered: DNA damage repair, metabolic activity generating energy and biosynthetic precursor molecules, and shaping of plasma membranes to promote T cell motility. In each of these domains, key molecules and pathways have now been identified, including the glycolytic enzymes PFKFB3 and G6PD; the DNA repair molecules ATM, DNA-PKcs and MRE11A; and the podosome marker protein TKS5. Some of these molecules may help in defining targetable pathways to slow the T cell aging process. Copyright © 2017 Elsevier Inc. All rights reserved.

    A free radical scavenger edaravone is clinically used in Japan for acute stroke, and several basic researches have carefully examined the mechanisms of edaravone's protective effects. However, its actions on pro-inflammatory responses under stroke are still understudied. In this study, we subjected adult male Sprague-Dawley rats to 90-min middle cerebral artery (MCA) occlusion followed by reperfusion. Edaravone was treated twice via tail vein; after MCA occlusion and after reperfusion. As expected, edaravone-treated group showed less infarct volume and edema formation compared with control group at 24-h after an ischemic onset. Furthermore, edaravone reduced the levels of plasma interleukin (IL)-1β and matrix metalloproteinase-9 at 3-h after ischemic onset. Several molecules besides IL-1β and MMP-9 are involved in inflammatory responses under stroke conditions. Therefore, we also examined whether edaravone treatment could decrease a wide range of pro-inflammatory cytokines/chemokines by testing rat plasma samples with a rat cytokine array. MCAO rats showed elevations in plasma levels of CINC-1, Fractalkine, IL-1α, IL-1ra, IL-6, IL-10, IP-10, MIG, MIP-1α, and MIP-3α, and all these increases were reduced by edaravone treatment. These data suggest that free radical scavengers may reduce systemic inflammatory responses under acute stroke conditions, and therefore, oxidative stress can be still a viable target for acute stroke therapy.

    The purpose of this study was to determine: 1) the extent to which an acute session of high-intensity interval training (HIIT) increases systemic inflammatory cytokines and chemokines, and 2) whether 2 weeks of HIIT training alters the inflammatory response. Eight recreationally active males (aged 22±2 years) performed 2 weeks of HIIT on a cycle ergometer (six HIIT sessions at 8–12 intervals; 60-second intervals, 75-second active rest) at a power output equivalent to 100% of their predetermined peak oxygen uptake (VO2max). Serum samples were collected during the first and sixth HIIT sessions at rest and immediately, 15, 30, and 45 minutes post-exercise. An acute session of HIIT induced significant increases in interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor-α, and monocyte chemotactic protein-1 compared with rest. The concentrations of interferon-γ, granulocyte macrophage-colony-stimulating factor, and IL-1β were unaltered with an acute session of HIIT Two weeks of training did not alter the inflammatory response to an acute bout of HIIT exercise. Maximal power achieved during a VO2max test significantly increased 4.6%, despite no improvements in VO2max after 2 weeks of HIIT. These data suggest that HIIT exercise induces a small inflammatory response in young, recreationally active men; however, 2 weeks of HIIT does not alter this response. PMID:24520199

    Psychological stressors reliably trigger systemic inflammatory activity as indexed by levels of proinflammatory cytokines. This experiment demonstrates that one's specific emotional reaction to a stressor may be a significant determinant of whether an inflammatory reaction occurs in response to that stressor. Based on extant correlational evidence and theory, a causal approach was used to determine whether an avoidant emotion (anxiety) triggers more inflammatory activity than an approach emotion (anger). In an experimental design (N = 40), a 3-way Emotion Condition × Time × Analyte interaction revealed that a writing-based anxiety induction, but not a writing-based anger induction, increased mean levels of interferon-γ (IFN- γ) and interleukin-1β (IL-1β), but not interleukin-6 (IL-6) in oral mucous, F(2, 54) = 4.64, p = .01, ηp(²) = .15. Further, self-reported state anxiety predicted elevated levels of proinflammatory cytokines, all ΔR(²) >.06, ps emotions can differentially cause inflammatory activity and support a theoretical model explaining these effects based on the avoidance or approach motivations associated with emotions.

    Full Text Available Abstract Background Food allergies are generally associated with gastrointestinal upset, but in many patients systemic reactions occur. However, the systemic effects of food allergies are poorly understood in experimental animals, which also offer the opportunity to explore the actions of anti-allergic drugs. The tripeptide D-phenylalanine-D-glutamate-Glycine (feG, which potentially alleviates the symptoms of systemic anaphylactic reactions, was tested to determine if it also reduced systemic inflammatory responses provoked by a gastric allergic reaction. Results Optimal inhibition of intestinal anaphylaxis was obtained when 100 μg/kg of feG was given 20 min before the rats were challenged with antigen. The increase in total circulating neutrophils and accumulation of neutrophils in the heart, developing 3 h and 24 h, respectively, after antigen challenge were reduced by both feG and dexamethasone. Both anti-inflammatory agents reduced the increase in vascular permeability induced by antigen in the intestine and the peripheral skin (pinna, albeit with different time courses. Dexamethasone prevented increases in vascular permeability when given 12 h before antigen challenge, whereas feG was effective when given 20 min before ingestion of antigen. The tripeptide prevented the anaphylaxis induced up regulation of specific antibody binding of a cell adhesion molecule related to neutrophil activation, namely CD49d (α4 integrin. Conclusions Aside from showing that intestinal anaphylaxis produces significant systemic inflammatory responses in non-intestinal tissues, our results indicate that the tripeptide feG is a potent inhibitor of extra-gastrointestinal allergic reactions preventing both acute (30 min and chronic (3 h or greater inflammatory responses.

    Full Text Available Background. Systemic lupus erythematosus (SLE in the basis of the pathogenesis has generalized autoimmune inflammation, which leads to the development of a wide range of immune-inflammatory organ disorders. Among them, the liver deserves special attention, since its functional state can reflect not only the severity of the pathological process, but also the response on aggressive treatment. The purpose of the work was studying the biochemical markers of the functional state of the liver in children with initial stages of SLE. Materials and methods. Features of the lipid, carbohydrate spectrum of the blood, indicators of pigment exchange, markers of cytolysis, cholestasis, fibrosis and protein-synthetic function of the liver were studied in children and adolescents with SLE. Twenty six patients aged 7–18 years were examined. Two groups were formed: 10 patients (38.4 % with the duration of the disease of 1–3 years and 16 people (61.5 % with duration of more than 3 years. Results. The average blood lipids levels did not exceed the reference values and did not have statistical differences among the patients of the selected groups. The levels of total cholesterol and triglycerides in both groups of patients significantly exceeded the control values (p < 0.05. Indicators of low density lipoprotein cholesterol increased already in the early stages of the disease (p < 0.05 and reached the maximum values in individuals with a course of SLE over 3 years (p < 0.05. Concentration of high density lipoprotein cholesterol in patients of the second group decreased somewhat (p < 0.1. There was an increase in the average values of atherogenic index by 1.7 times among patients in the first group (p < 0.05 and 2.25 times in persons from the second group (p < 0.05. Studies of other metabolic links showed that the average values of glycaemia and immunoreactive insulin (IRI were consistent with the physiological norm. However, half of patients with SLE had

    Vitamin C (ascorbic acid, AA) is a water soluble vitamin with many functions including antioxidative properties, haemostasis, hormone synthesis, collagen synthesis, carnitine synthesis, bile salt production and enhancing iron absorption. There is some evidence that there is a negative inverse relationship between plasma vitamin C concentration and the systemic inflammatory response as measured by C-reactive protein (CRP). The aim of the present study was to examine, in the context of a longitudinal study, the change in plasma concentrations of ascorbic acid (AA) and Vitamin E (α-tocopherol, AT) and their relationship to free radical damage during the evolution of the systemic inflammatory response. Venous blood samples were obtained pre-operatively and at 1, 2, 3 and 90 days post-operatively from 11 patients undergoing elective hip arthroplasty at Glasgow Royal Infirmary. AA, AT, cholesterol, MDA (marker of free radical damage), CRP and albumin were measured in plasma. Plasma AA fell significantly by 74% (P < 0.01), AT fell by 36% (P < 0.01), cholesterol by 40% (P < 0.01), MDA by 38% (P < 0.01), albumin by 29% (P < 0.01) and CRP increased significantly by 160 fold (P < 0.01) during the systemic inflammatory response. The fall in plasma AA remained significant when adjusted for albumin (P < 0.01). Plasma AT adjusted for cholesterol did not change significantly during the study period. The fall in plasma MDA remained significant when adjusted for albumin (P 0.01). At 3 months post-operatively, all measurements (including AA) except albumin had returned to baseline values. Plasma AA levels are unlikely to be a reliable measurement of Vitamin C where there is evidence of a systemic inflammatory response. The decrease in plasma AA concentration is likely to be secondary to increased consumption, increased usage neutralising free radicals, increased utilisation in supporting AT regeneration and increased urinary excretion.

    The molecular mechanism of herpes simplex virus (HSV) entry and the associated inflammatory response in the nervous system remain poorly understood. Using mouse-derived ex vivo dorsal root ganglia (DRG) explant model and single cell neurons (SCNs), in this study, we provided a visual evidence for the expression of heparan sulfate (HS) and 3-O-sulfated heparan sulfate (3-OS HS) followed by their interactions with HSV-1 glycoprotein B (gB) and glycoprotein D (gD) during cell entry. Upon heparanase treatment of DRG-derived SCN, a significant inhibition of HSV-1 entry was observed suggesting the involvement of HS role during viral entry. Finally, a cytokine array profile generated during HSV-1 infection in DRG explant indicated an enhanced expression of chemokines (LIX, TIMP-2, and M-CSF)-known regulators of HS. Taken together, these results highlight the significance of HS during HSV-1 entry in DRG explant. Further investigation is needed to understand which isoforms of 3-O-sulfotransferase (3-OST)-generated HS contributed during HSV-1 infection and associated cell damage.

    Full Text Available This paper is aimed at providing a comprehensive review of markers, cofactors and staging systems used for HIV disease, focusing on some aspects that nowadays could even be considered historical, and advancing in current issues such as the prognostic value of viral load measurements, viral genotypic and phenotypic characterization, and new HIV disease treatment protocols. CD4+ cell values, combined with the new viral markers mentioned are promising as a parsimonious predictor set for defining both severity and progression. An adequate predictor of patient resource use for planning purposes still needs to be defined

    Texture image segmentation is a constant challenge in digital image processing. The partition of an image into regions that allow the experienced observer to obtain the necessary information can be done using a Mathematical Morphology tool called the Watershed Transform. This transform is able to distinguish extremely complex objects and is easily adaptable to various kinds of images. The success of the Watershed Transform depends essentially on the existence of unequivocal markers for each of the objects of interest. The standard methods for marker detection are highly specific and complex when objects presenting great variability of shape, size and texture are processed. This paper proposes the automatic generation of a fuzzy inference system for marker detection using object selection done by the expert. This method allows applying the Watershed Transform to biomedical images with diferent kinds of texture. The results allow concluding that the method proposed is an effective tool for the application of the Watershed Transform

    Proinflammatory biomarkers levels are increased among patients with cardiovascular disease, and it is known that both the presence of insulin resistance and diet may influence those levels. However, these associations are not well studied among patients with established cardiovascular disease. Our objective is to compare inflammatory biomarker levels among cardiovascular disease secondary prevention patients with and without insulin resistance, and to evaluate if there is any association between plasma fatty acid levels and inflammatory biomarker levels among them. In this cross-sectional sub-study from the BALANCE Program Trial, we collected data from 359 patients with established cardiovascular disease. Plasma fatty acids and inflammatory biomarkers (interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-12, high sensitive C-reactive protein (hs-CRP), adiponectin, and tumor necrosis factor (TNF)-alpha) were measured. Biomarkers and plasma fatty acid levels of subjects across insulin resistant and not insulin resistant groups were compared, and general linear models were used to examine the association between plasma fatty acids and inflammatory biomarkers. Subjects with insulin resistance had a higher concentration of hs-CRP (p = 0.002) and IL-6 (p = 0.002) than subjects without insulin resistance. Among subjects without insulin resistance there was a positive association between stearic fatty acid and IL-6 (p = 0.032), and a negative association between alpha-linolenic fatty acid and pro-inflammatory biomarkers (p fatty acids and arachidonic fatty acid and adiponectin (p fatty acids and pro-inflammatory biomarkers (p fatty acids and adiponectin (p fatty acids. Subjects in secondary prevention for cardiovascular disease with insulin resistance have a higher concentration of hs-CRP and IL-6 than individuals without insulin resistance, and these inflammatory biomarkers are positively associated with saturated fatty acids and negatively associated with

    AIMS: The aim of this study was to investigate the prevalence of chronic kidney disease (CKD) among comparable patients with rheumatoid arthritis (RA) and seronegative inflammatory arthritis, and to explore any predictive factors for renal impairment. METHODS: Consecutive patients with peripheral joint disease (oligo and polyarthritis) were recruited from our inflammatory arthritis clinics. We divided patients in two groups: RA group and seronegative inflammatory arthritis group. The cohort consisted of 183 patients (RA = 107, seronegative arthritis = 76 [psoriatic arthritis = 69, undifferentiated oligoarthritis = 7]). Estimated glomerular filtration rate (eGFR) was calculated using the established Modification of Diet in Renal Disease equation. Demographic details, disease-specific characteristics, anti-rheumatic drugs and the presence of cardiovascular diseases were recorded. RESULTS: In total, 17.48% (n = 32) of the cohort had CKD. There was no statistically significant variation between the two groups as regards baseline demographics, disease characteristics, use of anti-rheumatic drugs and the presence of individual cardiovascular diseases. We found that eGFR and the presence of CKD were similar among these groups. Among patients with CKD, 72% had undiagnosed CKD. No association of statistical significance was noted between CKD and the use of corticosteroids, disease-modifying antirheumatic drugs and anti-tumor necrosis factor agents. The association of cardiovascular diseases with CKD remained significant after adjusting for confounders (age, gender, duration of arthritis, high C-reactive protein, use of anti-rheumatic drugs). CONCLUSIONS: Patients with inflammatory arthritis are more prone to have CKD. This could have serious implications, as the majority of rheumatology patients use non-steroidal anti-inflammatory drugs and different immunosuppressives, such as methotrexate. No association of kidney dysfunction was noted with inflammatory disease

    The co-occurrence of generalized anxiety disorder and personality disorders suggests the existence of association between the neurobiological predispositions leading to the development of these disorders and activation of cytokine system. Pro-inflammatory chemokines such as CCL-5/RANTES (regulated upon activation normal T cell expressed and secreted) and CXCL12/SDF-1 (stromal derived factor) play an important role in immune response. A total of 160 participants were enrolled in the study, 120 of whom comprised the study group (people with the dual diagnosis of personality disorder and generalized anxiety disorder). The mean age was 41.4 ± 3.5 years (range: 20-44 years). The control group consisted of 40 healthy individuals in the mean age of 40.8 ± 3.1 years (range: 20-43 years). A blood sample was collected from each participant and the plasma levels of the CCL-2/MCP-1 (monocyte chemoattractant protein-1), RANTES and SDF-1 chemokines were determined by ELISA. Increased levels of MCP-1 and SDF-1 were found both in women and in men versus the control group for all types of personality disorders. The levels of CCL-5 in men were significantly increased versus the control group and significantly higher in women than in men. Neither women nor men with avoidant or obsessive-compulsive personality disorder showed any significant differences in MCP-1 or SFD-1 levels. In subjects with borderline personality disorder, the levels of the study chemokines were higher in women than in men. Our study has shown the need for determination of proinflammatory interleukins which are considered as biomarkers of personality disorders and generalized anxiety disorders.

    Full Text Available Background/Purpose. HMGB1, which may act as a proinflammatory mediator, has been proposed to contribute to the pathogenesis of multiple chronic inflammatory and autoimmune diseases including systemic lupus erythematosus (SLE; however, the precise mechanism of HMGB1 in the pathogenic process of SLE remains obscure. Method. The expression of HMGB1 was measured by ELISA and western blot. The ELISA was also applied to detect proinflammatory cytokines levels. Furthermore, nephritic pathology was evaluated by H&E staining of renal tissues. Results. In this study, we found that HMGB1 levels were significantly increased and correlated with SLE disease activity in both clinical patients and murine model. Furthermore, gain- and loss-of-function analysis showed that HMGB1 exacerbated the severity of SLE. Of note, the HMGB1 levels were found to be associated with the levels of proinflammatory cytokines such as TNF-α and IL-6 in SLE patients. Further study demonstrated that increased HMGB1 expression deteriorated the severity of SLE via enhancing macrophage inflammatory response. Moreover, we found that receptor of advanced glycation end products played a critical role in HMGB1-mediated macrophage inflammatory response. Conclusion. These findings suggested that HMGB1 might be a risk factor for SLE, and manipulation of HMGB1 signaling might provide a therapeutic strategy for SLE.

    Abstract Rationale: Adult-onset Still disease (AOSD) is a rare systemic inflammatory disease of unknown etiology characterized by evanescent salmon-pink rash, fever spikes, arthralgia, and lymphadenopathy. AOSD usually has a good prognosis, but it can sometimes be fatal, especially when it is complicated by systemic inflammatory response syndrome (SIRS) and multiple organ failure. Patient concerns: A previously healthy 26-year-old woman was referred to our hospital for persistent high fever and mild systemic edema. Five days later, the patient presented with dyspnea, hypotension, and anuria. Anasarca developed with massive pleural effusion, ascites, and systemic edema, resulting in an increase of 47 kg in body weight. Diagnoses: The patient was diagnosed as AOSD after infection, malignancy, hematologic disorders, and other autoimmune diseases were excluded. Interventions: We administered tocilizumab, an IL-6 receptor inhibitor, intravenously in addition to cyclosporine, prednisolone, plasma exchange, and continuous hemodiafiltration. Outcomes: The patient's systemic condition improved. After stabilization by all medications, the patient was managed and responded to tocilizumab alone. To the best of our knowledge, this was the first case of severe SIRS complicating AOSD that was successfully treated with an anti- IL-6 receptor antibody. Lessons: SIRS should not be overlooked in a patient with steroid-resistant AOSD and edema. Inhibitors of the IL-6 receptor can be used safely and effectively to control AOSD complicated with severe SIRS. PMID:28723802

    Full Text Available Background. The inflammatory markers YKL-40 and monocyte chemoattractant protein-1 (MCP-1 are elevated in morbidly obese patients and decline after weight loss. The objective of our study was to investigate the possible changes of YKL-40 and MCP-1, in both the fasting and the postprandial states, following Roux-en-Y gastric bypass (RYGB in subjects with type 2 diabetes (T2D and normal glucose tolerance (NGT. Methods. Ten obese patients with T2D and 10 subjects with NGT were examined in the fasting state and after a standard meal prior to and after (1 week, 3 months, and 1 year RYGB. Results. Fasting state MCP-1 levels decreased after RYGB in both groups (P values < 0.0001 whereas fasting YKL-40 levels were unchanged (P values ≥ 0.120. Postprandial MCP-1 levels showed a tendency towards a decrease on most study days; however, the changes were only significant at 1 week (P=0.001 and 1 yr (P<0.0001 in the T2D group and at 3 mo after RYGB in the NGT group (P=0.009. YKL-40 levels showed a slight, postprandial suppression on all study days in the T2D group (all P values ≤ 0.021. Conclusions. Fasting MCP-1 levels, but not YKL-40 levels, decrease after RYGB in subjects with T2D and NGT. Postprandial changes of inflammatory markers are discrete and inconsistent.

    This study compared the effects of 12 weeks of high-intensity interval body weight training (HIBWT) with combined training (COMT; aerobic and resistance exercises on body composition, a 6-minute walk test (6MWT; physical performance), insulin resistance (IR) and inflammatory markers in postmenopausal women (PW) at high risk of type 2 diabetes mellitus (TDM2). In this randomized controlled clinical study, 16 PW at high risk of TDM2 were randomly allocated into two groups: HIBWT (n = 8) and COMT (n = 8). The HIBWT group performed a training protocol (length time ~28 min) consisting of ten sets of 60 s of high intensity exercise interspersed by a recovery period of 60 s of low intensity exercise. The COMT group performed a training protocol (length time ~60 min) consisting of a 30 min walk of moderate intensity following by five resistance exercises. All training sessions were performed in the university gym facility three days a week (no consecutive days) for 12 weeks. All outcomes (body composition, muscle function, and IR and inflammatory markers) were assessed at the baseline and at the end of the study. Both groups increased (P  0.05) from the effects of COMT. There was a significant (P high risk of TDM2. The patients were part of a 12-week training study (ClinicalTrials.gov Identifier: NCT03200639). Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available Chronic obstructive pulmonary disease (COPD and chronic heart failure (CHF may coexist in elderly patients with a history of smoking. Low-grade systemic inflammation induced by smoking may represent the link between these 2 conditions. In this study, we investigated left ventricular dysfunction in patients primarily diagnosed with COPD, and nonreversible airflow limitation in patients primarily diagnosed with CHF. The levels of circulating high-sensitive C-reactive protein (Hs-CRP, pentraxin 3 (PTX3, interleukin-1β (IL-1 β, and soluble type II receptor of IL-1 (sIL-1RII were also measured as markers of systemic inflammation in these 2 cohorts. Patients aged ≥ 50 years and with ≥ 10 pack years of cigarette smoking who presented with a diagnosis of stable COPD (n=70 or stable CHF (n=124 were recruited. All patients underwent echocardiography, N-terminal pro-hormone of brain natriuretic peptide measurements, and post-bronchodilator spirometry. Plasma levels of Hs-CRP, PTX3, IL-1 β, and sIL-1RII were determined by using a sandwich enzyme-linked immuno-sorbent assay in all patients and in 24 healthy smokers (control subjects. Although we were unable to find a single COPD patient with left ventricular dysfunction, we found nonreversible airflow limitation in 34% of patients with CHF. On the other hand, COPD patients had higher plasma levels of Hs-CRP, IL1 β, and sIL-1RII compared with CHF patients and control subjects (p < 0.05. None of the inflammatory biomarkers was different between CHF patients and control subjects. In conclusion, although the COPD patients had no evidence of CHF, up to one third of patients with CHF had airflow limitation, suggesting that routine spirometry is warranted in patients with CHF, whereas echocardiography is not required in well characterized patients with COPD. Only smokers with COPD seem to have evidence of systemic inflammation.

    Full Text Available Thirty-eight individuals (mean age: 34.8 years old participating in a 3-month yoga and meditation retreat were assessed before and after the intervention for psychometric measures, brain derived neurotrophic factor (BDNF, circadian salivary cortisol levels, and pro- and anti-inflammatory cytokines. Participation in the retreat was found to be associated with decreases in self-reported anxiety and depression as well as increases in mindfulness. As hypothesized, increases in the plasma levels of BDNF and increases in the magnitude of the cortisol awakening response (CAR were also observed. The normalized change in BDNF levels was inversely correlated with BSI-18 anxiety scores at both the pre-retreat (r = 0.40, p < 0.05 and post-retreat (r = 0.52, p < 0.005 such that those with greater anxiety scores tended to exhibit smaller pre- to post-retreat increases in plasma BDNF levels. In line with a hypothesized decrease in inflammatory processes resulting from the yoga and meditation practices, we found that the plasma level of the anti-inflammatory cytokine Interleukin-10 was increased and the pro-inflammatory cytokine Interleukin-12 was reduced after the retreat. Contrary to our initial hypotheses, plasma levels of other pro-inflammatory cytokines, including Interferon Gamma (IFN-γ, Tumor Necrosis Factor (TNF-α, Interleukin-1β (IL-1β, Interleukin-6 (IL-6, and Interleukin-8 (IL-8 were increased after the retreat. Given evidence from previous studies of the positive effects of meditative practices on mental fitness, autonomic homeostasis and inflammatory status, we hypothesize that these findings are related to the meditative practices throughout the retreat; however, some of the observed changes may also be related to other aspects of the retreat such as physical exercise-related components of the yoga practice and diet. We hypothesize that the patterns of change observed here reflect mind-body integration and well-being. The increased BDNF levels

    Full Text Available The lymphatic vascular system has been minimally explored in the liver despite its essential functions including maintenance of tissue fluid homeostasis. The discovery of specific markers for lymphatic endothelial cells has advanced the study of lymphatics by methods including imaging, cell isolation, and transgenic animal models and has resulted in rapid progress in lymphatic vascular research during the last decade. These studies have yielded concrete evidence that lymphatic vessel dysfunction plays an important role in the pathogenesis of many diseases. This article reviews the current knowledge of the structure, function, and markers of the hepatic lymphatic vascular system as well as factors associated with hepatic lymphangiogenesis and compares liver lymphatics with those in other tissues.

    Full Text Available Amyotrophic lateral sclerosis (ALS is a late-onset motor neuron disease where activated glia release pro-inflammatory cytokines that trigger a vicious cycle of neurodegeneration in the absence of resolution of inflammation. Given the well-established role of histamine as a neuron-to-glia alarm signal implicated in brain disorders, the aim of this study was to investigate the expression and regulation of the histaminergic pathway in microglial activation in ALS mouse model and in humans. By examining the contribution of the histaminergic system to ALS, we found that particularly via H1 and H4 receptors, histamine promoted an anti-inflammatory profile in microglia from SOD1-G93A mice by modulating their activation state. A decrease in NF-κB and NADPH oxidase 2 with an increase in arginase 1 and P2Y12 receptor was induced by histamine only in the ALS inflammatory environment, but not in the healthy microglia, together with an increase in IL-6, IL-10, CD163, and CD206 phenotypic markers in SOD1-G93A cells. Moreover, histaminergic H1, H2, H3, and H4 receptors, and histamine metabolizing enzymes histidine decarboxylase, histamine N-methyltransferase, and diamine oxidase were found deregulated in spinal cord, cortex, and hypothalamus of SOD1-G93A mice during disease progression. Finally, by performing a meta-analysis study, we found a modulated expression of histamine-related genes in cortex and spinal cord from sporadic ALS patients. Our findings disclose that histamine acts as anti-inflammatory agent in ALS microglia and suggest a dysregulation of the histaminergic signaling in ALS.

    Full Text Available Inflammatory response following central nervous system (CNS injury contributes to progressive neuropathology and reduction in functional recovery. Axons are sensitive to mechanical injury and toxic inflammatory mediators, which may lead to demyelination. Although it is well documented that degenerated myelin triggers undesirable inflammatory responses in autoimmune diseases such as multiple sclerosis (MS and its animal model, experimental autoimmune encephalomyelitis (EAE, there has been very little study of the direct inflammatory consequences of damaged myelin in spinal cord injury (SCI, i.e., there is no direct evidence to show that myelin debris from injured spinal cord can trigger undesirable inflammation in vitro and in vivo. Our data showed that myelin can initiate inflammatory responses in vivo, which is complement receptor 3 (CR3-dependent via stimulating macrophages to express pro-inflammatory molecules and down-regulates expression of anti-inflammatory cytokines. Mechanism study revealed that myelin-increased cytokine expression is through activation of FAK/PI3K/Akt/NF-kappaB signaling pathways and CR3 contributes to myelin-induced PI3K/Akt/NF-kappaB activation and cytokine production. The myelin induced inflammatory response is myelin specific as sphingomyelin (the major lipid of myelin and myelin basic protein (MBP, one of the major proteins of myelin are not able to activate NF-kappaB signaling pathway. In conclusion, our results demonstrate a crucial role of myelin as an endogenous inflammatory stimulus that induces pro-inflammatory responses and suggest that blocking myelin-CR3 interaction and enhancing myelin debris clearance may be effective interventions for treating SCI.

  8. Acute deviations from long-term trait depressive symptoms predict systemic inflammatory activity.

    2008-07-01

    Depressive symptoms increase morbidity and mortality from coronary heart disease and systemic inflammation has been proposed as the underlying mechanism. While higher levels of inflammatory mediators have been found in dysphoric individuals, it is not known whether long-term or short-term mood changes are responsible for this phenomenon. A sample of 65 young women provided weekly web-based self-ratings of depressive mood over a period of 20 weeks using the CES-D, and systemic inflammation was assessed by measuring plasma interleukin-6 (IL-6) and C-reactive protein (CRP) before and after the observation period. CES-D ratings were used to develop state and trait indicators of depressed mood and evaluate their relationship with inflammatory mediators. Hierarchical linear regressions controlling for baseline inflammation, age, and BMI revealed that trait levels of depressive symptoms were not associated with IL-6 (beta=0.09; n.s.) and CRP (beta=0.01; n.s.) concentrations after the observation period. In contrast, state levels of depressive symptoms were associated with changes in IL-6, but not CRP, particularly when they were indexed as the disparity between a person's trait level of symptoms and her CES-D score just prior to IL-6 assessment (beta=0.35; p=0.03). These results lead us to conclude that in young women, state, rather than trait depressed mood stimulates peripheral inflammation as measured by IL-6. This pattern suggests that in this age group, fast-reacting inflammatory mediators such as IL-6 probably respond to short-term changes, for example, in stress hormones or stress hormone sensitivity, rather than long-term dysregulations of allostatic mechanisms.

    Full Text Available The purpose. To study the factor structure and to establish the associative interaction of pathogenetic links of acute diseases development of the bronchopulmonary system in infants.Materials and methods. The examination group consisted of 59 infants (average age 13.8 ± 1.4 months sick with acute inflammatory bronchopulmonary diseases. Also we tested the level of 25-hydroxyvitamin D (25(ОНD, vitamin D-binding protein, hBPI, cathelicidin LL-37, ß1-defensins, lactoferrin in blood serum with the help of immunoenzymometric analysis. Selection of prognostically important pathogenetic factors of acute bronchopulmonary disease among infants was conducted using ROC-analysis. The procedure for classifying objects was carried out using Hierarchical Cluster Analysis by the method of Centroid-based clustering. Results. Based on the results of the ROC-analysis were selected 15 potential predictors of the development of acute inflammatory diseases of the bronchopulmonary system among infants. The factor analysis made it possible to determine the 6 main components . The biggest influence in the development of the disease was made by "the anemia factor", "the factor of inflammation", "the maternal factor", "the vitamin D supply factor", "the immune factor" and "the phosphorus-calcium exchange factor” with a factor load of more than 0.6. The performed procedure of hierarchical cluster analysis confirmed the initial role of immuno-inflammatory components. The conclusio
