  1. Evaluation of cardiac risk by oxidative stress and inflammatory markers in diabetic patients

    International Nuclear Information System (INIS)

    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.

    Full Text Available BACKGROUND: Identification of risk is essential to prevent cardiac allograft vasculopathy (CAV and graft failure due to CAV (GFDCAV in heart transplant patients, which account for 30% of all deaths. Early CAV detection involves invasive, risky, and expensive monitoring approaches. We determined whether prediction of CAV and GFDCAV improves by adding inflammatory markers to a previously validated atherothrombotic (AT model. METHODS AND FINDINGS: AT and inflammatory markers interleukin-6 (IL-6 and C-reactive protein (CRP were measured in heart biopsies and sera of 172 patients followed prospectively for 8.9±5.0 years. Models were estimated for 5- and 10-year risk using (1 the first post-transplant biopsy only, or (2 all biopsies obtained within 3 months. Multivariate models were adjusted for other covariates and cross-validated by bootstrapping. After adding IL-6 and CRP to the AT models, we evaluated the significance of odds ratios (ORs associated with the additional inflammatory variables and the degree of improvement in the area under the receiver operating characteristic curve (AUROC. When inflammatory markers were tested alone in prediction models, CRP (not IL-6 was a significant predictor of CAV and GFDCAV at 5 (CAV: p<0.0001; GFDCAV: p = 0.005 and 10 years (CAV: p<0.0001; GFDCAV: p = 0.003. Adding CRP (not IL-6 to the best AT models improved discriminatory power to identify patients destined to develop CAV (using 1st biopsy: p<0.001 and p = 0.001; using all 3-month biopsies: p<0.04 and p = 0.008 at 5- and 10-years, respectively and GFDCAV (using 1st biopsy: 0.92 vs. 0.95 and 0.86 vs. 0.89; using all 3-month biopsies: 0.94 vs. 0.96 and 0.88 vs. 0.89 at 5- and 10-years, respectively, as indicated by an increase in AUROC. CONCLUSIONS: Early inflammatory status, measured by a patient's CRP level (a non-invasive, safe and inexpensive test, independently predicts CAV and GFDCAV. Adding CRP to a previously established AT model

    Primary aldosteronism (PA) is the most common cause of endocrine hypertension with a high frequency of cardiovascular complications. The unfavorable cardiometabolic profile may be due to aldosterone-mediated activation of inflammatory cells, circulatory cytokines and activation of collagen synthesis in the vessel wall. Aim of our study was to evaluate differences in the levels of hsCRP, IL-6, TNF-alpha and N-terminal propeptide of collagen I (PINP) in patients with PA and essential hypertension (EH) as a control group, and between the subtypes of PA (aldosterone producing adenoma - APA, idiopathic hyperaldosteronism - IHA). We studied 28 patients with PA (IHA - 10 patients, APA - 12 patients, 6 unclassified) and 28 matched patients with EH. There were no differences in the levels of inflammatory markers between the followed groups [EH vs. PA: TNF-alpha (5.09 [3.68-6.32] vs. 4.84 [3.62-6.50] pg/ml), IL-6 (0.94 [0.70-1.13] vs. 0.97 [0.71-1.28] pg/ml), hsCRP (0.53 [0.25-1.54] vs. 0.37 [0.31-0.61] mg/l), leukocytes (6.35+/-1.42 vs. 5.97+/-1.29 10(9) l); APA vs. IHA: TNF-alpha (4.54 [3.62-7.03] vs. 5.19 [4.23-5.27] pg/ml), IL-6 (0.96 [0.63-1.21] vs. 0.90 [0.65-1.06] pg/ml), hsCRP (0.34 [0.29-0.47] vs. 0.75 [0.36-1.11] mg/l), leukocytes (6.37+/-1.41 vs. 5.71+/-1.21 10(9) l)]. Significant differences in the levels of PINP between PA and EH group were observed (35.18 [28.46-41.16] vs. 45.21 [36.95-62.81] microg/l, pinflammatory markers were observed between the followed groups, we confirmed higher levels of PINP in patients with PA.

  5. Inflammatory Genetic Markers of Prostate Cancer Risk

    International Nuclear Information System (INIS)

    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

  6. Evaluation of Some Inflammatory and Biochemical Markers in Acute Coronary Syndrome

    International Nuclear Information System (INIS)

    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

  8. Cardiac and inflammatory biomarkers do not correlate with volume of heart or lung receiving radiation

    International Nuclear Information System (INIS)

    Thoracic and cardiac irradiation increases the risk of pulmonary and cardiovascular disease. In addition, radiation, often in combination with chemotherapy, can cause treatment-related pneumonitis. Previously, we showed that the common marker for cardiac damage, troponin T, was not elevated by chemoradiation [Lung Cancer 62:351–355, 2008]. In this study, we explore whether dose-volume metrics and biomarkers for cardiac damage, inflammation or angiogenesis could identify patients receiving thoracic radiation who would later have cardiac or pulmonary complications. To this end, we quantified cardiac biomarkers including c-reactive protein (cRP) as well as a panel of angiogenic and inflammatory molecules in thirty patients who received radiation therapy to the thorax with or without concurrent chemotherapy between May 2006 and May 2007. Serum was collected at baseline, 2 weeks into radiation treatment and at the completion of radiation therapy. Heart and lung dosimetric parameters and clinical risk factors were also examined, along with the monitoring of adverse pulmonary and cardiac events during follow-up. Contrary to our hypothesis, there was no correlation between serum biomarker levels and cardiac radiation dose. Similarly there was little association between lung dose-volume metrics and inflammatory or angiogenic biomarkers. Furthermore, there was no correlation with serum biomarkers and adverse pulmonary or cardiovascular events. Based on these data, acute elevations in serum biomarkers of cardiac damage, inflammation or angiogenesis should not be attributed to thoracic (chemo)radiation and elevations in such biomarkers of tissue damage should be further evaluated

  14. Role of cardiac FDG PET-CT in inflammatory cardiomyopathy

    International Nuclear Information System (INIS)

    Full text: Role of cardiac FDG PET-CT in the diagnosis and monitoring treatment response of inflammatory cardiomyopathy. Materials and Methods: This is a retrospective analysis of 72 patients (over a period of 3 years) referred for cardiac PET-CT with dilated cardiomyopathy (DCM) or idiopathic ventricular tachycardia (VT), to rule out inflammatory cardiomyopathy. FDG cardiac PET was done with patients following very high fat low carbohydrate protein preferred diet (VHFLCPPD) protocol one day prior to scan. Myocardial perfusion scan with 99mTc-tetrofosmin or 13N-NH3 was done prior to FDG PET. All patients underwent breathhold CECT, chest PET-CT and cardiac PET-CT 45 min post FDG injection. Scans were reported jointly by a radiologist and nuclear medicine physician. Clinical/pathological follow-up was obtained where possible. Results: 50(69.4%) patients had positive myocardial FDG uptake with matched perfusion defect on NH3/Tc scan in the absence of CAD. 30(42%) patients had associated metabolically active lymphadenopathy and organ lesions. 4 patients had metabolically active lymphnodes with no myocardial inflammation. 18 patients had no abnormality detected on the scan. Patients with positive lymphnodes underwent biopsy and proven to have granulomatous disease either sarcoidosis and with TB or TB alone. 15 patients had post treatment scan which showed complete metabolic response in 7, partial response in 6 and stable disease in 2. Conclusion: Evaluating patients with DCM or idiopathic VT secondary to inflammatory myocarditis is challenging. Cardiac PET scan with VHFLCPPD protocol is the most sensitive modality available for assessment of disease activity in inflammatory cardiomyopathy and monitoring the treatment response especially in patients with ICD

  15. Role of peripheral inflammatory markers in postoperative cognitive dysfunction (POCD: a meta-analysis.

    Linying Peng

    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.

In view of the fact that inflammatory cells have estrogen receptors, we hypothesized that estrogen provides cardioprotection by decreasing the ability of cardiac inflammatory cells to influence fibroblast function. Methods: Male rats were assigned to either an untreated or estrogen-treated group. In the treated group, estrogen was delivered for 2 weeks via a subcutaneous implanted pellet containing 17β-estradiol. A mixed population of cardiac inflammatory cells, including T-lymphocytes (about 70%, macrophages (about 12%, and mast cells (about 12%, was isolated from each rat and cultured in a Boyden chamber with cardiac fibroblasts from untreated adult male rats for 24 hours. To examine if tumor necrosis factor-alpha (TNF-α produced by inflammatory cells represents a mechanism contributing to the stimulatory effects of inflammatory cells on cardiac fibroblasts, inflammatory cells from the untreated group were incubated with cardiac fibroblasts in a Boyden chamber system for 24 hours in the presence of a TNF-α -neutralizing antibody. Cardiac fibroblasts were also incubated with 5 ng/mL of TNF-α for 24 hours. Fibroblast proliferation, collagen synthesis, matrix metalloproteinase activity, β1 integrin protein levels, and the ability of fibroblasts to contract collagen gels were determined in all groups and statistically compared via one-way analysis of variance. Results: Inflammatory cells from the

    Objective The object of this study was to review the role of cardiac troponin as a prognostic factor in acute coronary syndrome patients of varying circumstances.Data sources The data used in this review were obtained mainly from the studies of cardiac troponin reported in pubmed from 1981 to 2006.Study selection Relevant articles on studies of cardiac troponin were selected.Results Elevated cardiac troponin in patients with ST elevation and non ST elevation myocardial infarction was associated with adverse outcomes, including a higher incidence of congestive heart failure, shock, and death. Patients with elevated cardiac troponin value seemed to benefit more from invasive strategies including a percutaneous coronary intervention and bypass surgery, but elevated cardiac troponin was also correlated with adverse outcomes, including a higher degree of failure, shock, and mortality in patients undergoing percutaneous coronary intervention; a higher degree of perioperative myocardial infarction, low cardiac output syndrome, cardiopulmonary resuscitation, and new-onset ventricular arrhythmia in patients undergoing bypass surgery were also observed. Elevated troponin after a percutaneous coronary intervention seemed to be associated with short-term adverse outcomes rather than long-term adverse outcomes, unless the elevation of the troponin post percutaneous coronary intervention was quite high (about 5 times above normal). On the contrary, elevated cardiac troponin after bypass surgery was more confusing to analyze since it happened in almost all patients. Furthermore, differences in cutoff values and time measurements in some studies add more confusion; thus, further research is warranted.Conclusions The prognostic value of cardiac troponin is demonstrated in almost all acute coronary syndrome patients. In addition to its high sensitivity and specificity, the prognostic value of cardiac troponin is another reason to make it the "golden cardiac marker' of this time.

    Full Text Available OBJECTIVE: To correlate the audio-logical profile in diabetes mellitus with inflammatory markers (TNFα, IL-6, CRP, and FREE RAICALS. MATERIALS AND METHODS: A two year prospective study of Audio-logical profile and its correlation with inflammatory markers was done in 35 diabetic patients attending Diabetic OPD and ENT OPD at RMMCH between 2012- 2014.Patients with diabetes mellitus on oral hypoglycaemic agents or insulin therapy was subjected to Pure Tone Audiometry using Arphi Audiometer-Model 700MK4 and Inflammatory marker study. STATISTICS AND ANALYSIS: P-value was found out by ANOVA method to find out the significance of auditory thresholds between various categories of parameters. RESULTS: Patients with Diabetes Mellitus were more commonly affected by Sensori-neural Hearing loss in the age group between 41- 49 years accounting for 77.14%. Females were more affected in our study in the ratio3.3:1. Hearing loss was bilaterally symmetrical and of sensori-neural type affecting mainly the higher frequencies. In 77.1% of our patients the duration of diabetes mellitus was less than 5years, however there was no correlation between the duration of diabetes mellitus and hearing loss. Control in the severity of diabetes mellitus lead to improvement in hearing thresholds, which was statistically significant at higher frequencies. CONCLUSION: There was a positive correlation between increased level of inflammatory markers-TNF α, IL-6, CRP, free radicals and hearing loss in diabetes mellitus. However the inclusion of elevated markers as a prognostic index to assess the degree of deafness and its relation to microangiopathy needs further studies and its role in prevention of deafness in diabetes mellitus needs further evaluation.

    Full Text Available AbstractBackground and purpose: Coronary heart disease is one of the main causes of death and disability in human society. Nowadays, one of the ways of identifying the risk factors is to examine the inflammatory markers.The purpose of this research was to study the relation of inflammatory markers with the intensity of coronary involvement, which is distinguished through angiography.Materials and Methods: In this cross sectional-analytical study 200 patients, whom undergone angiography at Mazandaran Heart Center during 2004-5, were recruited. The intensity of the coronary heart involvement was determined based on angiography or the number of involved vessels and the intensity of vessel narrowness. The patients were then divided into two groups: high risk and low risk. The patients’ information was recorded in a questionnaire and in order to study the inflammatory markers, their blood was sampled to measure WBC, platelet, ESR and CRP. Data were analyzed using T and chi-square tests, in SPSS version 11.Results: One hundred and fifty seven (%78.5 out of the 200 patients were men Ninty four patients (%47 were put in high risk group and 106 (%53 in low risk group. There was no significant relationship between gender, job, body mass index, education, duration of heart disease, suffering from diabetis mellitus, dyslipidemia, smoking, the number of WBC, platelet and ESR with the intensity of coronary heart disease. Patients of high risk group attended the hospital more frequently than low risk group, because of heart disease (P=%24 and that the amount of CRP in these patients was more than the low risk group significantly (P=%47.Conclusion: Regarding the inflammatory markers, it seems that only CRP has a relationship with the intensity of the coronary involvement.More studies for examining the causes, effects and suggesting interventions for the control of the condition seem to be necessary.

    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.

    associations were calculated within each study and then combined using random-effects meta-analyses. RESULTS: Mean baseline CCA-IMT amounted to 0.74 mm (SD = 0.18) and mean CCA-IMT progression over a mean of 3.9 years to 0.011 mm/year (SD = 0.039). Cross-sectional analyses showed positive linear associations.......0025 mm for leucocyte count (p = 0.033). 'Inflammatory load', defined as the number of elevated inflammatory markers (i.e. in upper two quintiles), showed a positive linear association with baseline CCA-IMT (p < 0.001). Longitudinal associations of baseline inflammatory markers and changes therein with...... CCA-IMT progression were null or at most weak. Participants with the highest 'inflammatory load' had a greater CCA-IMT progression (p = 0.015). CONCLUSION: Inflammation was independently associated with CCA-IMT cross-sectionally. The lack of clear associations with CCA-IMT progression may be explained...

    Full Text Available Yaser Elnahar, Joseph Daoko, Karim El Kersh, Jennifer C Kam, Chady Sarraf, Fayez ShamoonSt. Michael’s Medical Center, Newark, NJ, USAAbstract: The availability of troponins as cardiac markers in the diagnosis of acute coronary syndrome is invaluable. However, their elevation can sometimes lead the physician astray. We report a rare case of an 86-year-old Hispanic female with a past medical history significant for asthma, hypertension, atrial fibrillation, and dyslipidemia, who presented to the emergency room complaining of a two-day history of shortness of breath associated with wheezing. She denied any chest pain. The patient’s wheezing ameliorated with bronchodilator treatment. However, her admission laboratory investigations were positive for elevated troponin I, with normal creatine kinase (CK and CK-myoglobin (MB. The first set of cardiac enzymes revealed a troponin I of 29.16 ng/mL (normal < 0.05 ng/mL, CK 234 IU/L, and CK-MB 3.9 IU/L. The electrocardiogram showed rate-controlled atrial fibrillation with nonspecific ST changes. Subsequent cardiac enzymes failed to show any increase in CK or CK-MB. However, the troponin I was, as on admission, persistently elevated at 20.87–29.16 ng/mL. Subsequent cardiac catheterization revealed mild nonobstructive coronary artery disease. Other laboratory tests showed normal creatinine, alkaline phosphatase, and bilirubin, and a negative rheumatoid factor, with absence of hemolysis. A blood sample was subsequently drawn and sent to Beckman Coulter laboratories for heterophile antibody testing. The results confirmed our suspicion of a falsely elevated troponin I caused by the presence of a heterophile antibody. The addition of blocking agents yielded troponin I levels in the normal range. Consistent with current guidelines, we conclude that cardiac markers should be used in conjunction with the clinical picture and the electrocardiogram. This case is unique in that the troponin elevation was

    Full Text Available Recent studies from the Gulf region suggest that compared to men, women have a greater risk of developing metabolic syndrome (MeS. Objective. To investigate gender differences in body composition, adipokines, inflammatory markers, and aerobic fitness in a cohort of healthy Qatari adults. Participants. Healthy Qatari (n=58 were matched for age, gender, and body mass index. Methods. Body composition and regional fat distribution were determined by dual-energy X-ray absorptiometry and computerized tomography. Laboratory assessments included serum levels of fasting glucose, insulin, lipid profile analysis, adipokines, and inflammatory markers. Subjects were also evaluated for aerobic fitness. Results. Women had more adipose tissue in the total abdominal (P=0.04 and abdominal subcutaneous (P=0.07 regions compared to men. Waist circumference and indices of insulin sensitivity were similar; however, women had a more favourable lipid profile than men. Serum adiponectin and leptin levels were significantly higher in women, whereas inflammatory profiles were not different between men and women. Aerobic fitness was lower in women and was associated with abdominal fat accumulation. Conclusion. In premenopausal women, higher levels of adiponectin may support maintenance of insulin sensitivity and normolipidemia despite greater adiposity. However, poor aerobic fitness combined with abdominal fat accumulation may explain their greater future risk of MeS compared with men.

    The post-mortem diagnosis of acute myocardial ischemia remains a challenge for both clinical and forensic pathologists. We performed an experimental study (ligation of left anterior descending coronary artery in rats) in order to identify early markers of myocardial ischemia, to further apply to forensic and clinical pathology in cases of sudden cardiac death. Using immunohistochemistry, Western blots, and gene expression analyses, we investigated a number of markers, selected among those which are currently used in emergency departments to diagnose myocardial infarction and those which are under investigation in basic research and autopsy pathology studies on cardiovascular diseases. The study was performed on 44 adult male Lewis rats, assigned to three experimental groups: control, sham-operated, and operated. The durations of ischemia ranged between 5 min and 24 h. The investigated markers were troponins I and T, myoglobin, fibronectin, C5b-9, connexin 43 (dephosphorylated), JunB, cytochrome c, and TUNEL staining. The earliest expressions (≤30 min) were observed for connexin 43, JunB, and cytochrome c, followed by fibronectin (≤1 h), myoglobin (≤1 h), troponins I and T (≤1 h), TUNEL (≤1 h), and C5b-9 (≤2 h). By this investigation, we identified a panel of true early markers of myocardial ischemia and delineated their temporal evolution in expression by employing new technologies for gene expression analysis, in addition to traditional and routine methods (such as histology and immunohistochemistry). Moreover, for the first time in the autopsy pathology field, we identified, by immunohistochemistry, two very early markers of myocardial ischemia: dephosphorylated connexin 43 and JunB.

    Full Text Available Background: Inflammation has been proposed as a contributor to different stages in the pathogenesis of Coronary Heart Disease (CHD. High sensitive C-Reactive Protein (hs-CRP, an acute-phase plasma protein synthesized by the liver, is the most extensively studied systemic marker of inflammation. Elevated hsCRP concentrations early in Acute Coronary Syndrome (ACS, prior to the tissue necrosis, may be a surrogate marker for cardiovascular co-morbidities. The cardiac marker enzymes Creatine Kinase myocardial bound (CK-MB, Aspartate Aminotransferase (AST and lactate dehydrogenase (LDH have been known to be increased in coronary artery diseases. Objective: The aim of the study was to measure hs-CRP levels and other cardiac marker enzymes in ACS patients and to compare the levels of hs-CRP with other cardiac marker enzymes between ST Elevation Myocardial Infarction (STEMI and Non-ST Elevation Myocardial Infarction (NSTEMI patients. Material and Methods: The study group consisted of 207 consecutive patients admitted to Sri Siddhartha Medical College Hospital within the first 6 hours from the onset of chest pain. Patients were diagnosed as Unstable Angina (UA, (n=84; STEMI (n=63 and NSTEMI (n=60. ACS patients were compared with 211 healthy age and sex matched controls. Hs-CRP, CK-MB, AST and LDH levels were measured by standard methods in both groups at baseline and forcases at 36-48 hours i.e. Peak levels. Results: ACS patients had significantly (p<0.05 higher levels of hs-CRP, CKMB, AST and LDH in comparison to controls at baseline. Hs-CRP, CK-MB, AST and LDH levels were significantly higher in STEMI patients compared to NSTEMI patients (p<0.05 at baseline. There was a significant difference regarding peak hs-CRP levels between the two groups, as STEMI patients had significantly higher peak hs-CRP levels compared to NSTEMI patients (p<0.05. Conclusion: STEMI patients have significantly higher peak hsCRP levels compared to NSTEMI patients. These data

    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.

  13. Inflammatory Bio marker Levels in Obese Prepubertal Children

    International Nuclear Information System (INIS)

    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/m2), 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

    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 Abstract Background Inflammatory breast cancer (IBC is the most aggressive form of breast cancer. In non-IBC, the cysteine protease cathepsin B (CTSB is known to be involved in cancer progression and invasion; however, very little is known about its role in IBC. Methods In this study, we enrolled 23 IBC and 27 non-IBC patients. All patient tissues used for analysis were from untreated patients. Using immunohistochemistry and immunoblotting, we assessed the levels of expression of CTSB in IBC versus non-IBC patient tissues. Previously, we found that CTSB is localized to caveolar membrane microdomains in cancer cell lines including IBC, and therefore, we also examined the expression of caveolin-1 (cav-1, a structural protein of caveolae in IBC versus non-IBC tissues. In addition, we tested the correlation between the expression of CTSB and cav-1 and the number of positive metastatic lymph nodes in both patient groups. Results Our results revealed that CTSB and cav-1 were overexpressed in IBC as compared to non-IBC tissues. Moreover, there was a significant positive correlation between the expression of CTSB and the number of positive metastatic lymph nodes in IBC. Conclusions CTSB may initiate proteolytic pathways crucial for IBC invasion. Thus, our data demonstrate that CTSB may be a potential prognostic marker for lymph node metastasis in IBC.

    Full Text Available Abstract Inflammatory myofibroblastic tumor is currently considered to be a low-grade neoplasm, and it rarely involves the heart. We reported a rare case of a 59-year-old female who received cardiac surgery for complete resection of inflammatory myofibroblastic tumor in the left atrium. Five months after surgery, the patient presented with acute cardiogenic pulmonary edema and subsequent sudden death due to a left atrial tumor which protruded into the left ventricle through mitral annulus during diastole. The recurrence of inflammatory myofibroblastic tumor in the left atrium was strongly suggested clinically.

    Sudden cardiac death (SCD) accounts for approximately 15-20% of all deaths worldwide. While the majority of SCDs occur in adults, children, and adults strategy for both primary and secondary prevention of SCD is the implantable cardioverter-defibrillator (ICD). However, identification of patients who will benefit from ICD implantation remains challenging. Left ventricular ejection fraction (LVEF) is the most frequent imaging parameter used to select patients for ICD implantation for primary prevention. However, LVEF has shown to be suboptimal for prediction of benefit. Non-invasive cardiac imaging permits characterization of the arrhythmogenic substrate, including dispersion of electromechanical activation, presence of myocardial scar, and cardiac innervation status. The arrhythmogenic substrate may change across the different underlying diseases. While in ischemic cardiomyopathy, differentiation and characterization of infarct core and peri-infarct zone have been shown to refine the risk stratification of patients, in non-ischemic cardiomyopathies, the substrate may be more heterogeneous and tissue characterization assessing focal and diffuse fibrosis and inflammation processes may be more relevant. Furthermore, in channelopathies, assessment of mechanical dispersion between myocardial layers may identify the patients with increased risk of ventricular arrhythmias. Finally, potential triggers of ventricular arrhythmias such as myocardial ischemia can be evaluated. The role of noninvasive imaging in the risk stratification of SCD and the selection of candidates for ICD will be discussed in this article. PMID:26632012

    Introduction Subclinical hypothyroidism shows the mimic reaction more like to frank hypothyroidism which creates the dilemma. Inflammatory markers can be helpful in assessment of adverse effects of subclinical hypothyroidism, are not very well studied in the past. So the aim of this study was to investigate the role of inflammatory markers in Subclinical hypothyroidism patients. Materials and Methods The study population consisted of 154 patients with recently diagnosed subclinical hypothyroidism and 100 healthy controls. TSH, FT4 & T3 were estimated by enzyme linked Immunosorbent assay (ELISA) for diagnosis of subclinical hypothyroidism. Total cholesterol, triglycerides, and HDL-C were estimated by spectrophotometric method. LDL – C was calculated by Friedewald formula. Inflammatory markers (ESR, C-reactive protein & Interleukin 6) were also estimated by enzyme linked Immunosorbent assay (ELISA). Results In this study the level of TSH Mean ± SD (11.12±4.17 vs 2.73±0.80) and T3 Mean ± SD (0.96±0.17 vs 1.08±0.26) were significantly higher (<0.001) in subclinical hypothyroidism. Serum concentration of FT4 was not significantly different between the groups. Total cholesterol, triglycerides, and LDL-C were significantly higher in patients group. While the level of HDL-C was significantly lower in SCH patients compared to euthyroid group. TSH level was positively correlated with inflammatory markers in subclinical hypothyroidism, which were significantly different in subclinical hypothyroidism. Conclusion This study suggests that subclinical hypo-thyroidism patients have increased inflammatory markers along with dyslipidemia and due to that future risk of further development of cardiovascular disorder can occur. Level of inflammatory markers increases in patients as disease progress if left untreated. PMID:26674140

    Background No one can deny that the biological importance of vitamin D is much beyond its classical role in bone metabolism. 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 possible role of vitamin D as a contributing factor in balancing cytokines toward an anti-inflammatory role in inflammatory situations.

    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.

    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.

    Objective During the aging process in men testosterone (T) levels progressively fall and inflammatory biomarkers increase. Although a relationship between these two phenomena has been tested in previous clinical trials, there is inconclusive evidence about the potential anti-inflammatory action of T. Methods A total of 108 healthy men >65 years with serum T concentration age ± SD at baseline was 71.8 ± 4.9 years. Testosterone replacement therapy for 36 months did not induce a significant decrease in inflammatory markers. A trend toward a significant increase was observed in the placebo group for TNF-alpha (p=0.03) and sgp130 (p=0.01). Significant differences, in estimated means of TNFR1 (but not of other inflammatory markers), with lower levels in T group, were observed at 36 month-time point. In T-treated subjects we found an almost significant treatment-time interaction term TNFR1 (p=0.02) independent of total body fat content assessed by DXA. No serious adverse effect was observed. Conclusions Transdermal T treatment of older men for 36 months is not associated with significant changes in inflammatory markers. PMID:25100359

    Full Text Available BACKGROUND: Breakdown of the gut mucosal barrier during chronic HIV infection allows translocation of bacterial products such as lipopolysaccharides (LPS from the gut into the circulation. Microbial translocation also occurs in inflammatory bowel disease (IBD. IBD serological markers are useful in the diagnosis of IBD and to differentiate between Crohn's disease (CD and ulcerative colitis (UC. Here, we evaluate detection of IBD serological markers in HIV-infected patients with advanced disease and their relationship to HIV disease markers. METHODS: IBD serological markers (ASCA, pANCA, anti-OmpC, and anti-CBir1 were measured by ELISA in plasma from AIDS patients (n = 26 with low CD4 counts (<300 cells/µl and high plasma LPS levels, and results correlated with clinical data. For meta-analysis, relevant data were abstracted from 20 articles. RESULTS: IBD serological markers were detected in approximately 65% of AIDS patients with evidence of microbial translocation. An antibody pattern consistent with IBD was detected in 46%; of these, 75% had a CD-like pattern. Meta-analysis of data from 20 published studies on IBD serological markers in CD, UC, and non-IBD control subjects indicated that IBD serological markers are detected more frequently in AIDS patients than in non-IBD disease controls and healthy controls, but less frequently than in CD patients. There was no association between IBD serological markers and HIV disease markers (plasma viral load and CD4 counts in the study cohort. CONCLUSIONS: IBD serological markers may provide a non-invasive approach to monitor HIV-related inflammatory gut disease. Further studies to investigate their clinical significance in HIV-infected individuals are warranted.

    Camellia oil is commonly used as an adjuvant in medicine. It is rich in monounsaturated fatty acids, vitamin E, and phytochemicals. The objective of this study was to examine effects of camellia oil consumption on oxidative stress, low-density lipoprotein-cholesterol (LDL-C) oxidation, and inflammatory markers in hypercholesterolemic subjects. The study design was a randomized, single-blind controlled trial. Women with hypercholesterolemia (n = 50) were randomly divided into two groups. The treatment group (n = 25) was provided camellia oil-enriched diets and the control group (n = 25) was provided diets cooked with soybean oil three meals (45 mL oil) a day for 8 weeks. Biomarkers of oxidative stress and inflammatory cytokines were assessed before and the after intervention. Camellia oil consumption significantly decreased malondialdehyde (11.2%; P stress and inflammatory markers in hypercholesterolemic women. Therefore, camellia oil consumption may reduce cardiovascular disease risk factors. PMID:27627703

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

    Directory of Open Access Journals (Sweden)

    Mark J Soloski

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

    Frédéric F Little

    Full Text Available RATIONALE: There is a need for a readily available, non-invasive source of biomarkers that predict poor asthma control. OBJECTIVES: We sought to determine if there is an association between the salivary inflammatory profile and disease control in children and adults with asthma. METHODS: In this cross-sectional study, we collected demographic and clinical information from two independent populations at different sites, resulting in convenience samples of 58 pediatric and 122 adult urban asthmatics. Control was assessed by symptom questionnaire (children and by Asthma Control Questionnaire and current exacerbation (adults. Saliva was collected in all subjects. We applied principal component analysis to a 10-plex panel of relevant inflammatory markers to characterize marker profiles and determined if profiles were associated with asthma control. RESULTS: There were similar, strong correlations amongst biologically related markers in both populations: eosinophil-related: eotaxin-1/CCL11, RANTES/CCL5, and IL-5 (p<.001; myeloid/innate: IL-1β, IL-6, MCP-1/CCL2, and IL-8/CXCL8 (p<.001. The first three principal components captured ≥74% of variability across all ten analytes in both populations. In adults, the Principal Component 1 score, broadly reflective of all markers, but with greater weight given to myeloid/innate markers, was associated with Asthma Control Questionnaire score and exacerbation. The Principal Component 3 score, reflective of IP-10/CXCL10, was associated with current exacerbation. In children, the Principal Component 1, 2, and 3 scores were associated with recent asthma symptoms. The Principal Component 2 score, reflective of higher eosinophil markers, was inversely correlated with symptoms. The Principal Component 3 score was positively associated with all symptom outcomes. CONCLUSION: The salivary inflammatory profile is associated with disease control in children and adults with asthma.

  6. Attenuated age-impact on systemic inflammatory markers in the presence of a metabolic burden.

    Directory of Open Access Journals (Sweden)

    Anuurad Erdembileg

    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.

    Inflammatory proteins are thought to be causally involved in the generation of aggression, possibly due to direct effects of cytokines in the central nervous system and/or by generation of inflammatory metabolites along the tryptophan-kynurenine (TRP/KYN) pathway, including KYN and its active metabolites kynurenic acid (KA), quinolinic acid (QA), and picolinic acid (PA). We examined plasma levels of TRP, KYN, KA, QA, and PA in 172 medication-free, medically healthy, human subjects to determine if plasma levels of these substances are altered as a function of trait aggression, and if they correlate with current plasma levels of inflammatory markers. Plasma levels of C-reactive protein (CRP), interleukin-6 (IL-6), and soluble interleukin-1 receptor-II (sIL-1RII) protein were also available in these subjects. We found normal levels of TRP but reduced plasma levels of KYN (by 48%), QA (by 6%), and a QA/KA (by 5%) ratio in subjects with Intermittent Explosive Disorder (IED) compared to healthy controls and psychiatric controls. Moreover, the metabolites were not associated with any of the inflammatory markers studied. These data do not support the hypothesis that elevated levels of KYN metabolites would be present in plasma of subjects with IED, and associated with plasma inflammation. However, our data do point to a dysregulation of the KYN pathway metabolites in these subjects. Further work will be necessary to replicate these findings and to understand their role in inflammation and aggression in these subjects. PMID:27318828

  9. Assessment of inflammatory factors and cardiac troponin T in hemodialysis patients

    International Nuclear Information System (INIS)

    Hemodialysis (Hd) patients suffer from chronic inflammations which make them at increased risk of cardiovascular diseases. The purpose of this study was to see if there is a significant association between inflammatory factors such as ferritin and C-reactive protein (CRP) as well as troponin T in patients on HD. We assessed these serum factors as well as other known cardiac risk factors in 53 patients on HD. The serum ferritin and CRP levels were measured by chemiluminescences immune assay while troponin T levels were measured by electrochemist luminescence immune assay. We found that serum concentrations of CRP and ferritin were not significantly higher in patients on HD with known cardiac risk factors (compared with the control group) (p< 0.05). However, the serum troponin T levels in HD patients with cardiovascular risk factors were significantly higher than the control group. Our study suggests that elevated serum troponin T levels can play an important role as a predictor of cardiovascular disease in HD patients. Also, inflammatory factors such as CRP and ferritin may be influenced by chronic inflammation or nutritional status of these patients. (author)

    Introduction. Mesenchymal stromal cells (MSC) have immunomodulatory features. The aim of this study was to investigate the migration and homing potential of endogenous circulating MSC in virus negative inflammatory cardiomyopathy (CMi). Methods. In 29 patients with (n = 23) or without (n = 6) CMi undergoing endomyocardial biopsies (EMB), transcardiac gradients (TCGs) of circulating MSC were measured by flow cytometry from blood simultaneously sampled from aorta and coronary sinus. The presence of MSC in EMB, cardiac inflammation, and SDF-1α mRNA expression were detected via immunohistochemistry and real-time PCR. Results. MSC defined as CD45(-)CD34(-)CD11b(-)CD73(+)CD90(+) cells accounted for 0.010 [0.0025-0.048]%/peripheral mononuclear cell (PMNC) and as CD45(-)CD34(-)CD11b(-)CD73(+)CD105(+) cells for 0.019 [0.0026-0.067]%/PMNC, both with similar counts in patients with or without cardiac inflammation. There was a 29.9% (P TCG of circulating MSC and numbers of MSC (CD45(-)CD34(-)CD90(+)CD105(+)) in EMB (r = -0.73, P < 0.005). SDF-1α was the strongest predictor for increased MSC in EMB (P < 0.005, multivariate analysis). Conclusions.

    Previous data have demonstrated that administration of inflammatory cytokines or their inducers leads to altered basal ganglia function associated with reduced psychomotor speed. Decreased psychomotor speed, referred to clinically as psychomotor retardation, is a cardinal symptom of major depressive disorder (MDD) and has been associated with poor antidepressant treatment response. We therefore examined the association between plasma inflammatory markers and psychomotor speed in ninety-three un-medicated patients with MDD. Psychomotor speed was assessed by a range of neuropsychological tests from purely motor tasks (e.g. movement latency and finger tapping) to those that involved motor activity with increasing cognitive demand and cortical participation (e.g. Trails A and Digit Symbol Substitution Task (DSST)). Linear regression analyses were performed to determine the relationship of inflammatory markers and psychomotor task performance controlling for age, race, sex, education, body mass index, and severity of depression. MDD patients exhibited decreased psychomotor speed on all tasks relative to normative standards. Increased IL-6 was associated with decreased performance on simple and choice movement time tasks, whereas MCP-1 was associated with decreased performance on the finger tapping task and DSST. IL-10 was associated with increased performance on the DSST. In an exploratory principle component analysis including all psychomotor tasks, IL-6 was associated with the psychomotor speed factor. Taken together, the data indicate that a peripheral inflammatory profile including increased IL-6 and MCP-1 is consistently associated with psychomotor speed in MDD. These data are consistent with data demonstrating that inflammation can affect basal ganglia function, and indicate that psychomotor speed may be a viable outcome variable for anti-inflammatory therapies in depression and other neuropsychiatric disorders with increased inflammation.

Aim: To evaluate leukocytes and neutrophils in the serum of pregnant women with preeclampsia and to compare these values to normal pregnancy. To investigate a possible relation between the detected values and the severity of preeclamptic syndrome. Material and method: A transversal study was performed in three groups of patients: group 1 (preeclampsia, group 2 (normal pregnancy, group 3 (control. The samples were processed using a multichannel automated hematology analyzer – ACCOS 319. The results obtained were processed by descriptive and comparative statistical methods. Results: A significant increase in leukocyte and neutrophil values was found in preeclampsia compared to normal pregnancy. Also, for group 2 (PE, there was no correlation between the number of leukocytes, neutrophils, respectively, and SBP and uric acid values, but a significant correlation was found between the studied inflammatory markers and DBP values. Conclusions: Leukocyte and neutrophil values can be considered markers of the inflammatory syndrome present in preeclampsia. These parameters were positively correlated with DBP values.

    Full Text Available Introduction. Obesity and obstructive sleep apnea syndrome (OSA are common coexisting conditions associated with a chronic low-grade inflammatory state underlying some of the cognitive, metabolic, and cardiovascular morbidities. Aim. 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. Results. 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. Conclusion. 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.

    Full Text Available Diabetes mellitus (DM is an independent risk factor for heart disease and its underlying mechanisms are unclear. Increased expression of diabetic marker miR-29 family miRNAs (miR-29a, b and c that suppress the pro-survival protein Myeloid Cell Leukemia 1(MCL-1 is reported in pancreatic β-cells in Type 1 DM. Whether an up-regulation of miR-29 family miRNAs and suppression of MCL-1 (dysregulation of miR-29-MCL-1 axis occurs in diabetic heart is not known. This study tested the hypothesis that insulin regulates cardiac miR-29-MCL-1 axis and its dysregulation correlates with DM progression. In vitro studies with mouse cardiomyocyte HL-1 cells showed that insulin suppressed the expression of miR-29a, b and c and increased MCL-1 mRNA. Conversely, Rapamycin (Rap, a drug implicated in the new onset DM, increased the expression of miR-29a, b and c and suppressed MCL-1 and this effect was reversed by transfection with miR-29 inhibitors. Rap inhibited mammalian target of rapamycin complex 1 (mTORC1 signaling in HL-1 cells. Moreover, inhibition of either mTORC1 substrate S6K1 by PF-4708671, or eIF4E-induced translation by 4E1RCat suppressed MCL-1. We used Zucker diabetic fatty (ZDF rat, a rodent model for DM, to test whether dysregulation of cardiac miR-29-MCL-1 axis correlates with DM progression. 11-week old ZDF rats exhibited significantly increased body weight, plasma glucose, insulin, cholesterol, triglycerides, body fat, heart weight, and decreased lean muscle mass compared to age-matched lean rats. Rap treatment (1.2 mg/kg/day, from 9-weeks to 15-weeks significantly reduced plasma insulin, body weight and heart weight, and severely dysregulated cardiac miR-29-MCL1 axis in ZDF rats. Importantly, dysregulation of cardiac miR-29-MCL-1 axis in ZDF rat heart correlated with cardiac structural damage (disorganization or loss of myofibril bundles. We conclude that insulin and mTORC1 regulate cardiac miR-29-MCL-1 axis and its dysregulation caused by reduced

    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.

    Inflammatory bowel disease (IBD) shows an increasing prevalence and harm in western countries. Conventional therapies are associated with bad compliance and adverse side effects. Natural substances like cinnamon extract (CE) could be an additional therapy. We found recently that CE acts anti-inflammatory on mast cells - discussed of being relevant in IBD. Here, we analysed the effects of CE on murine IL-10(-/-) colitis as model for IBD. Mice were treated 12 weeks with or without CE in drinking water. Clinical scores and disease activity index were assessed. Colonic tissue samples were analysed for infiltration, tissue damage, bowel wall thickness, expression of pro-inflammatory mediators, mast cell proteases, tight junction proteins, and NF-κB signaling. Following treatment with CE, symptoms of murine colitis as well as increased infiltration of immune cells, tissue damage and bowel wall thickness in colon tissue of IL-10(-/-) mice were diminished significantly. MIP-2, TNF, IFNγ, CCL2, CCL3, CCL4 and IL-1β as well as MC-CPA, MCP-1 and MCP-4 were strongly upregulated in IL-10(-/-) mice compared to WT, but noteworthy not in CE group. Expression of tight junction proteins was not influenced by CE. Phosphorylation of IκB was slightly down-regulated in CE treated IL-10(-/-) mice compared to IL-10(-/-) controls. In summary, CE decreases inflammatory symptoms and expression of inflammatory markers in murine IL-10(-/-) colitis. CE has no influence on tight junction proteins, but seems acting via reducing pro-inflammatory mediators and recruitment of neutrophil granulocytes probably by inhibiting NF-κB signaling.

    Full Text Available Objective. We evaluated inflammatory cytokines and chemokine in peripheral blood mononuclear cells (PBMCs in patients with either acute coronary syndrome (ACS or stable coronary artery disease (CAD. Methods. We enrolled 20 ACS patients and 50 stable CAD patients without previous history of ACS who underwent cardiac catheterization. Patients with an estimated glomerular filtration rate of ≤30 mL/min/1.73 m2 and C-reactive protein of ≥1.0 mg/dL were excluded. Blood samples were collected from the patients just before catheterization, and PBMCs were isolated from the whole blood. The levels of inflammatory cytokines and chemokine were measured by using real-time quantitative polymerase chain reaction and immunoassays. Results. The expression of tumor necrosis factor alpha (TNF-α, interleukin- (IL- 6, IL-10, IL-23A, IL-27, and IL-37 was significantly higher in the ACS group than in the CAD group (P<0.05. In contrast, the expression of IL-33 was significantly lower in the ACS group than in the CAD group (P<0.05. The ACS patients had higher plasma levels of TNF-α, IL-6, and IL-10 in the ACS group than in the CAD group. Conclusion. Circulating levels of pro-/anti-inflammatory cytokines, including IL-23A, IL-27, IL-33, and IL-37, may be associated with the pathogenesis of atherosclerosis in ACS patients.

    We report ∼17.6 million genetic variants from whole-genome sequencing of 2,120 Sardinians; 22% are absent from previous sequencing-based compilations and are enriched for predicted functional consequences. Furthermore, ∼76,000 variants common in our sample (frequency >5%) are rare elsewhere (<0.5% in the 1000 Genomes Project). We assessed the impact of these variants on circulating lipid levels and five inflammatory biomarkers. We observe 14 signals, including 2 major new loci, for lipid levels and 19 signals, including 2 new loci, for inflammatory markers. The new associations would have been missed in analyses based on 1000 Genomes Project data, underlining the advantages of large-scale sequencing in this founder population. PMID:26366554

    Evidence remains inconclusive about the association of systemic inflammatory markers with colorectal neoplasia. We investigated whether circulating inflammatory markers were associated with risk of advanced colorectal adenoma. We measured plasma macrophage inhibitory cytokine-1 (MIC-1), C-reactive protein (CRP), interleukin-6 (IL6), and soluble TNF receptor 2 (sTNFR-2) in blood samples drawn from 32,826 women in 1989 to 1990 in the Nurses' Health Study. Through 2008, we documented 757 cases of advanced colorectal adenomas (≥1 cm or any size with advanced histology); each case was matched by age and time of blood draw with one control randomly selected from participants who underwent lower endoscopy and did not have neoplasia. Plasma MIC-1 was associated with higher risk of advanced adenoma (Ptrend = 0.04), with an OR of 1.55 (95% confidence interval, 1.03-2.32) comparing extreme quintiles of MIC-1 after adjusting for colorectal cancer-risk factors and other inflammatory markers. Among cases, MIC-1 level was positively associated with the number of adenomas (P < 0.001) and gradually increased from adenomas located in the rectum, distal colon, and up to the proximal colon. There was a strong positive association between MIC-1 and risk of adenomas with multiplicity, ≥1 cm size and location in the proximal colon (all Ptrend < 0.05). CRP, IL6, or sTNFR-2 was not associated with adenoma risk. In conclusion, plasma MIC-1 was associated with higher risk of colorectal adenoma, especially multiple, large, and proximal adenomas. Our results provide further support for a role for MIC-1 in carcinogenesis and the potential for MIC-1 as an adjunctive biomarker for detection of advanced colorectal adenoma. PMID:26511487

  2. [11C]-Acetoacetate PET imaging: a potential early marker for cardiac heart failure

    International Nuclear Information System (INIS)

    The ketone body acetoacetate could be used as an alternate nutrient for the heart, and it also has the potential to improve cardiac function in an ischemic–reperfusion model or reduce the mitochondrial production of oxidative stress involved in cardiotoxicity. In this study, [11C]-acetoacetate was investigated as an early marker of intracellular damage in heart failure. Methods: A rat cardiotoxicity heart failure model was induced by doxorubicin, Dox(+). [14C]-Acetoacetate, a non-positron (β −) emitting radiotracer, was used to characterize the arterial blood input function and myocardial mitochondrial uptake. Afterward, [11C]-acetoacetate (β +) myocardial PET images were obtained for kinetic analysis and heart function assessment in control Dox(−) (n = 15) and treated Dox(+) (n = 6) rats. The uptake rate (K1) and myocardial clearance rate (k2or kmono) were extracted. Results: [14C]-Acetoacetate in the blood was increased in Dox(+), from 2 min post-injection until the last withdrawal point when the heart was harvested, as well as the uptake in the heart and myocardial mitochondria (unpaired t-test, p < 0.05). PET kinetic analysis of [11C]-acetoacetate showed that rate constants K1, k2 and kmono were decreased in Dox(+) (p < 0.05) combined with a reduction of 24% of the left ventricular ejection fraction (p < 0.001). Conclusion: Radioactive acetoacetate ex vivo analysis [14C], and in vivo kinetic [11C] studies provided evidence that [11C]-acetoacetate can assess heart failure Dox(+). Contrary to myocardial flow reserve (rest–stress protocol), [11C]-acetoacetate can be used to assess reduced kinetic rate constants without requirement of hyperemic stress response. The proposed [11C]-acetoacetate cardiac radiotracer in the investigation of heart disease is novel and paves the way to a potential role for [11C]-acetoacetate in cardiac pathophysiology

    Full Text Available Valvular interstitial cells (VICs are the main population of cells found in cardiac valves. These resident fibroblastic cells play important roles in maintaining proper valve function, and their dysregulation has been linked to disease progression in humans. Despite the critical functions of VICs, their cellular composition is still not well defined for humans and other mammals. Given the limited availability of healthy human valves and the similarity in valve structure and function between humans and pigs, we characterized porcine VICs (pVICs based on expression of cell surface proteins and sorted a specific subpopulation of pVICs to study its functions. We found that small percentages of pVICs express the progenitor cell markers ABCG2 (~5%, NG2 (~5% or SSEA-4 (~7%, whereas another subpopulation (~5% expresses OB-CDH, a type of cadherin expressed by myofibroblasts or osteo-progenitors. pVICs isolated from either aortic or pulmonary valves express most of these protein markers at similar levels. Interestingly, OB-CDH, NG2 and SSEA-4 all label distinct valvular subpopulations relative to each other; however, NG2 and ABCG2 are co-expressed in the same cells. ABCG2(+ cells were further characterized and found to deposit more calcified matrix than ABCG2(- cells upon osteogenic induction, suggesting that they may be involved in the development of osteogenic VICs during valve pathology. Cell profiling based on flow cytometry and functional studies with sorted primary cells provide not only new and quantitative information about the cellular composition of porcine cardiac valves, but also contribute to our understanding of how a subpopulation of valvular cells (ABCG2(+ cells may participate in tissue repair and disease progression.

    Makiko Miyata

    Full Text Available BACKGROUND: Senescence marker protein 30 (SMP30, which was originally identified as an aging marker protein, is assumed to act as a novel anti-aging factor in the liver, lungs and brain. We hypothesized that SMP30 has cardio-protective function due to its anti-aging and anti-oxidant effects on doxorubicin (DOX-induced cardiac dysfunction. METHODS AND RESULTS: SMP30 knockout (SMP30 KO mice, SMP30 transgenic (SMP30 TG mice with cardiac-specific overexpression of SMP30 gene and wild-type (WT littermate mice at 12-14 weeks of age were given intra-peritoneal injection of DOX (20 mg/kg or saline. Five days after DOX injection, echocardiography revealed that left ventricular ejection fraction was more severely reduced in the DOX-treated SMP30 KO mice than in the DOX-treated WT mice, but was preserved in the DOX-treated SMP30 TG mice. Generation of reactive oxygen species and oxidative DNA damage in the myocardium were greater in the DOX-treated SMP30 KO mice than in the DOX-treated WT mice, but much less in the SMP30 TG mice. The numbers of deoxynucleotidyltransferase-mediated dUTP nick end-labeling positive nuclei in the myocardium, apoptotic signaling pathways such as caspase-3 activity, Bax/Bcl-2 ratio and phosphorylation activity of c-Jun N-terminal kinase were increased in SMP30 KO mice and decreased in SMP30 TG mice compared with WT mice after DOX injection. CONCLUSIONS: SMP30 has a cardio-protective role by anti-oxidative and anti-apoptotic effects in DOX-induced cardiotoxicity, and can be a new therapeutic target to prevent DOX-induced heart failure.

    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.

    Jörg Eberhard

    Full Text Available OBJECTIVES: We here investigated whether experimental gingivitis enhances systemic markers of inflammation which are also known as surrogate markers of atherosclerotic plaque development. BACKGROUND: 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. METHODS: 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. RESULTS: The partial cessation of oral hygiene procedures was followed by the significant increase of gingival bleeding (34.0%, P<0.0001. This local inflammation was associated with a systemic increase in hsCRP (0.24 mg/L, P = 0.038, IL-6 (12.52 ng/L, P = 0.0002 and MCP-1 (9.10 ng/l, P = 0.124 in peripheral blood samples between baseline and day 21, which decreased at day 42. Monocytes showed an enhanced adherence to endothelial cells and increased foam cell formation after oxLDL uptake (P<0.050 at day 21 of gingivitis. CONCLUSIONS: 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.

    Microglia, the immune cells of the CNS, are highly adaptive cells that can acquire different pro- and anti-inflammatory activation states with distinct functions in CNS homeostasis and pathologies. To study microglial function in vitro, primary microglia or immortalized cell lines are commonly used. An alternative to these cells are embryonic stem cell-derived microglia (ESdM). ESdM have previously been shown to be very similar to primary microglia in terms of expression profiles and surface molecules. In this study, ESdM and primary microglia were treated with different inflammatory stimulants to analyze their ability to adopt different activation states. Using quantitative real-time PCR, comparative transcriptomics, ELISA, and flow cytometry, we found that different activation states can be induced in ESdM, which are similar to those found in primary microglia. These states are characterized by specific sets of inflammatory marker molecules and differential transcriptome signatures. Our results show that ESdM are a valuable alternative cell model to study microglial functions and neuroinflammatory mechanisms. GLIA 2016;64:1007-1020. PMID:26959607

  8. Polymorphism in the alpha cardiac muscle actin 1 gene is associated to susceptibility to chronic inflammatory cardiomyopathy.

    Amanda Farage Frade

    Full Text Available AIMS: Chagas disease, caused by the protozoan Trypanosoma cruzi is endemic in Latin America, and may lead to a life-threatening inflammatory dilated, chronic Chagas cardiomyopathy (CCC. One third of T. cruzi-infected individuals progress to CCC while the others remain asymptomatic (ASY. A possible genetic component to disease progression was suggested by familial aggregation of cases and the association of markers of innate and adaptive immunity genes with CCC development. Since mutations in multiple sarcomeric genes, including alpha-cardiac actin (ACTC1 have been involved in hereditary dilated cardiomyopathy, we investigated the involvement of the ACTC1 gene in CCC pathogenesis. METHODS AND RESULTS: We conducted a proteomic and genetic study on a Brazilian study population. The genetic study was done on a main cohort including 118 seropositive asymptomatic subjects and 315 cases and the replication was done on 36 asymptomatic and 102 CCC cases. ACTC1 protein and mRNA levels were lower in myocardial tissue from patients with end-stage CCC than those found in hearts from organ donors. Genotyping a case-control cohort of CCC and ASY subjects for all informative single nucleotide polymorphism (SNP in the ACTC1 gene identified rs640249 SNP, located at the 5' region, as associated to CCC. Associations are borderline after correction for multiple testing. Correlation and haplotype analysis led to the identification of a susceptibility haplotype. Functional assays have shown that the rs640249A/C polymorphism affects the binding of transcriptional factors in the promoter regions of the ACTC1 gene. Confirmation of the detected association on a larger independent replication cohort will be useful. CONCLUSIONS: Genetic variations at the ACTC1 gene may contribute to progression to chronic Chagas Cardiomyopathy among T. cruzi-infected patients, possibly by modulating transcription factor binding to ACTC1 promoter regions.

    Background:Increasing evidence supports an association between periodontitis and systemic diseases.Leptin is involved both in the energy metabolism and inflammatory processes and is suggested to be a link between periodontal infection and systemic health.The present study aimed to evaluate the peripheral leptin concentration in patients with aggressive periodontitis (AgP) and to explore the relationship between leptin and systemic inflammation.Methods:Ninety patients with AgP visiting the Clinic of the Periodontology Department,Peking University School and Hospital of Stomatology between July 2001 and May 2006,and 44 healthy controls (staffand student volunteers in the same institute) were recruited.Plasma levels of leptin and inflammatory cytokines including interleukin (IL)-1β,I L-6,tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP) were measured by enzyme-linked immunosorbent assay.Correlation and multiple linear regression analysis were performed to analyze the association between plasma leptin level and other variables.Results:Plasma leptin level of AgP group was significantly higher than that of the control group (19.7-4.4 ng/ml vs.7.5 ± 1.3 ng/ml,P < 0.01).After controlling for age,gender,and body mass index,positive correlation was observed between plasma leptin concentration and log-transformed levels of pro-inflammatory cytokines (IL-1β,IL-6,TNF-α and CRP),and the partial correlation coefficients ranged from 0.199 to 0.376 (P < 0.05).Log-transformed IL-1β and I L-6 levels entered the final regression model (standardized β were 0.422 and 0.461 respectively,P < 0.01).Conclusions:Elevated plasma leptin concentration may be associated with increased systemic levels of inflammatory markers in AgP patients.

    Full Text Available Studies have demonstrated that angiotensin II has been involved in immune and inflammatory responses which might contribute to the pathogenesis of immune-mediated diseases. Recent evidence suggests that oxidative stress may play a role in myocarditis. Here, we investigated whether olmesartan, an AT1R antagonist protects against experimental autoimmune myocarditis (EAM by suppression of oxidative stress, endoplasmic reticulum (ER stress and inflammatory cytokines. EAM was induced in Lewis rats by immunization with porcine cardiac myosin, were divided into two groups and treated with either olmesartan (10 mg/kg/day or vehicle for a period of 21 days. Myocardial functional parameters measured by hemodynamic and echocardiographic analyses were significantly improved by the treatment with olmesartan compared with those of vehicle-treated rats. Treatment with olmesartan attenuated the myocardial mRNA expressions of proinflammatory cytokines, [Interleukin (IL-1β, monocyte chemoattractant protein-1, tumor necrosis factor-α and interferon-γ] and the protein expression of tumor necrosis factor-α compared with that of vehicle-treated rats. Myocardial protein expressions of AT1R, NADPH oxidase subunits (p47phox, p67phox, gp91phox and the expression of markers of oxidative stress (3-nitrotyrosine and 4-hydroxy-2-nonenal, and the cardiac apoptosis were also significantly decreased by the treatment with olmesartan compared with those of vehicle-treated rats. Furthermore, olmesartan treatment down-regulated the myocardial expressions of glucose regulated protein-78, growth arrest and DNA damage-inducible gene, caspase-12, phospho-p38 mitogen-activated protein kinase (MAPK and phospho-JNK. These findings suggest that olmesartan protects against EAM in rats, at least in part via suppression of oxidative stress, ER stress and inflammatory cytokines.

    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. PMID:26525643

    Full Text Available 3D environment and high cell density play an important role in restoring and supporting the phenotypes of cells represented in cardiac tissues. The aim of this study was therefore to investigate the suitability of high density sphere (HDS cultures for studies of cardiomyocyte-, endothelial-, and stem-cell biology. Primary adult cardiac cells from nine human biopsies were cultured using different media for up to 9 weeks. The possibilities to favor a certain cell phenotype and induce production of extra cellular matrix (ECM were studied by histology, immunohistochemistry, and quantitative real-time PCR. Defined media gave significant increase in both cardiac- and progenitor-specific markers and also an intraluminal position of endothelial cells over time. Cardiac media showed indication of differentiation and maturity of HDS considering the ECM production and activities within NOTCH regulation but no additional cardiac differentiation. Endothelial media gave no positive effects on endothelial phenotype but increased proliferation without fibroblast overgrowth. In addition, indications for early vasculogenesis were found. It was also possible to affect the Wnt signaling in HDS by addition of a glycogen synthase kinase 3 (GSK3 inhibitor. In conclusion, these findings show the suitability of HDS as in vitro model for studies of cardiomyocyte-, endothelial-, and stem-cell biology.

    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. Blood samples used for cholinesterases evaluation were collected on days 0, 2, 7, 12, 27, 42, 57, 87, 102 and 118 days post-inoculation (PI. 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. Foram utilizados 12 coelhos adultos, fêmeas, da raça Nova Zelândia, divididos em dois grupos: um grupo controle, com seis animais (coelhos 1-6, e um grupo infectado, com seis animais (coelhos 7-12. Os animais pertencentes ao grupo infectados receberam, pela via intraperitoneal, 0,5 mL de sangue de rato contendo 108 tripanossomas por animal. Amostras do sangue utilizado para avaliação das colinesterases foram coletadas nos dias 0, 2, 7, 12, 27, 42, 57, 87, 102 e 118 pós-inoculação (PI. Aumento (P0,05 foi observada nas estruturas encefálicas. O aumento de atividade da AChE e BChE provavelmente tenha finalidade pró-inflamatória, a fim de reduzir as concentrações de acetilcolina, neurotransmissor que apresenta propriedade anti-inflamatória. Portanto, as colinesterases podem ser marcadores inflamatórios na infec

Underlying etiologies include severe pulmonary infection and cystic fibrosis (CF; however, in a substantial number of patients with non-CF-related bronchiectasis (NCFB, no cause is found. The increasing armamentarium of therapies now available to combat disease in CF is in stark contrast to the limited tools employed in NCFB. Our study aimed to evaluate similarities and differences in airway inflammatory markers in patients with NCFB and CF, and to suggest potential common treatment options. The results of this study show that NCFB bronchoalveolar lavage fluid samples possessed significantly increased NE activity and elevated levels of matrix metalloproteinases 2 (MMP-2 and MMP-9 compared to healthy controls (P < 0.01; however, the levels detected were lower than in CF (P < 0.01. Interleukin-8 (IL-8 concentrations were significantly elevated in NCFB and CF compared to controls (P < 0.05, but in contrast, negligible levels of IL-18 were detected in both NCFB and CF. Analogous concentrations of IL-10 and IL-4 measured in NCFB and CF were statistically elevated above the healthy control values (P < 0.05 and P < 0.01, respectively. These results indicate high levels of important proinflammatory markers in both NCFB and CF and support the use of appropriate anti-inflammatory therapies already employed in the treatment of CF bronchiectasis in NCFB.Keywords: bronchiectasis, cystic fibrosis, proteases, inflammation

    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.

    The objective of this study was to assess the influence of an asymptomatic experimental infection by Babesia bigemina on cholinesterase's as markers of the inflammatory process and biomarkers of oxidative imbalance. For this purpose, eight naive animals were used, as follows: four as controls or uninfected; and four infected with an attenuated strain of B. bigemina. Blood samples were collected on days 0, 7 and 11 post-inoculation (PI). Parasitemia was determined by blood smear evaluation, showing that the infection by B. bigemina resulted in mean 0.725 and 0.025% on day 7 and 11 PI, respectively, as well as mild anemia. The activities of acetylcholinesterase, butyrylcholinesterase and catalase were lower, while levels of thiobarbituric acid reactive substances and superoxide dismutase activity were higher in infected animals, when compared with the control group. This attenuated strain of B. bigemina induced an oxidative stress condition, as well as it reduces the cholinesterasés activity in infected and asymptomatic cattle. Therefore, this decrease of cholinesterase in infection by B. bigemina purpose is to inhibit inflammation, for thereby increasing acetylcholine levels, potent anti-inflammatory molecules.

    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.

    Bacteriophages are increasingly considered an alternative to antibiotics for the treatment of bacterial infections. Clinical improvement may be associated with a lowering of inflammatory markers during the antibiotic treatment of bacterial infections. Some experimental data suggest that phage treatment may have anti-inflammatory properties. We present a retrospective analysis of C-reactive protein (CRP) serum concentration, erythrocyte sedimentation rate (ESR), and white blood cell count (WBC) measured in patients with chronic, symptomatic, antibiotic therapy-resistant bacterial infections who qualified for phage treatment within the protocol "Experimental Phage Therapy of Antibiotic Therapy-Resistant Infections, Including MRSA Infections". Data collected from 37 patients with osteomyelitis (with or without metal implants or joint endoprosthesis) or skin and soft tissue or lower respiratory tract infection induced by, in the majority of cases, S. aureus were analyzed. Phage preparations (natural phage lysates) were administered orally (one 10-ml ampoule three times daily after neutralization of gastric juice with 10 ml of dihydroxyaluminium sodium carbonate) and/or locally (one ampoule two times daily for wet compresses or irrigation of a fistula). No significant changes in mean serum levels of CRP measured after 5-8 days of phage administration were observed compared with the baseline CRP levels measured before therapy (35.7 vs. baseline 38.6 mg/l, n = 11). However, a significant decrease in mean CRP values measured later, between days 9 and 32, was noted (16.1 vs. baseline 23.3 mg/l, n = 26, P therapy did not change significantly. This is the first report suggesting that the application of phage preparations may probably influence and diminish the inflammatory reaction that accompanies bacterial infection. PMID:19350363

    Full Text Available OBJECTIVE: The aim of the present study was to evaluate the effect of 8 weeks of aerobic exercise training on cardiac functioning and remodeling and on the plasma levels of inflammatory cytokines in chronic heart failure rats. METHODS: Wistar rats were subjected to myocardial infarction or sham surgery and assigned to 4 groups: chronic heart failure trained (n = 7, chronic heart failure sedentary (n = 6, sham trained (n = 8 and sham sedentary (n = 8. Four weeks after the surgical procedures, the rats were subjected to aerobic training in the form of treadmill running (50 min/day, 5 times per week, 16 m/min. At the end of 8 weeks, the rats were placed under anesthesia, the hemodynamic variables were recorded and blood samples were collected. Cardiac hypertrophy was evaluated using the left ventricular weight/body weight ratio, and the collagen volume fraction was assessed using histology. RESULTS: The chronic heart failure trained group showed a reduction in left ventricular end-diastolic pressure, a lower left ventricular weight/body weight ratio and a lower collagen volume fraction compared with the chronic heart failure sedentary group. In addition, exercise training reduced the plasma levels of TNF-α and IL-6 and increased the plasma level of IL-10. CONCLUSION: An 8-week aerobic exercise training program improved the inflammatory profile and cardiac function and attenuated cardiac remodeling in chronic heart failure rats.

    Cardiac progenitor cells (CPCs) from adult myocardium offer an alternative cell therapy approach for ischaemic heart disease. Improved clinical performance of CPCs in clinical trials requires a comprehensive definition of their biology and specific interactions with the environment. In this work we characterize specific human CPC surface markers and study some of their related functions. c-kit(pos) human CPCs (hCPCs) were characterized for cell surface marker expression, pluripotency, early and late cardiac differentiation markers and therapeutic activity in a rat model of acute myocardial infarction. The results indicate that hCPCs are a mesenchymal stem cell (MSC)-like population, with a similar immunoregulatory capacity. A partial hCPC membrane proteome was analysed by liquid chromatography-mass spectrometry/mass spectrometry and 36 proteins were identified. Several, including CD26, myoferlin and podocalyxin-like protein 1 (PODXL), have been previously described in other stem-cell systems. Suppression and overexpression analysis demonstrated that PODXL regulates hCPC activation, migration and differentiation; it also modulates their local immunoregulatory capacity. Therefore, hCPCs are a resident cardiac population that shares many features with hMSCs, including their capacity for local immunoregulation. Expression of PODXL appears to favour the immature state of hCPCs, while its downregulation facilitates their differentiation. Copyright © 2016 John Wiley & Sons, Ltd. PMID:23897803

    Full Text Available Abstract Background Placental malaria (PM is an important cause of maternal and foetal mortality in tropical areas, and severe sequelae and mortality are related to inflammation in the placenta. Diagnosis is difficult because PM is often asymptomatic, peripheral blood smear examination detects parasitemia as few as half of PM cases, and no peripheral markers have been validated for placental inflammation. Methods In a cohort of Tanzanian parturients, PM was determined by placental blood smears and placental inflammation was assessed by histology and TNF mRNA levels. Maternal peripheral blood levels of several immune mediators previously implicated in PM pathogenesis, as well as ferritin and leptin were measured. The relationship between the levels of these soluble factors to PM and placental inflammation was examined. Results Peripheral levels of TNF, TNF-RI, TNF-RII, IL-1, IL-10, and ferritin were elevated during PM, whereas levels of IFN-γ, IL-4, IL-5 and IL-6 were unchanged and levels of leptin were decreased. In receiver operating characteristic curve analysis, IL-10 had the greatest area under the curve, and would provide a sensitivity of 60% with a false positive rate of 10%. At a cut off level of 15 pg/mL, IL-10 would detect PM with a sensitivity of 79.5% and a specificity of 84.3%. IL-10 levels correlated with placental inflammatory cells and placental TNF mRNA levels in first time mothers. Conclusion These data suggest that IL-10 may have utility as a biomarker for inflammatory PM in research studies, but that additional biomarkers may be required to improve clinical diagnosis and management of malaria during pregnancy.

  8. Inflammatory transcription factors as activation markers and functional readouts in immune-to-brain communication.

    2016-05-01

    Immune-to-brain communication pathways involve humoral mediators, including cytokines, central modulation by neuronal afferents and immune cell trafficking to the brain. During systemic inflammation these pathways contribute to mediating brain-controlled sickness symptoms including fever. Experimentally, activation of these signaling pathways can be mimicked and studied when injecting animals with pathogen associated molecular patterns (PAMPS). One central component of the brain inflammatory response, which leads, for example, to fever induction, is transcriptional activation of brain cells via cytokines and PAMPS. We and others have studied the spatiotemporal activation and the physiological significance of transcription factors for the induction of inflammation within the brain and the manifestation of fever. Evidence has revealed a role of nuclear factor (NF)κB in the initiation, signal transducer and activator of transcription (STAT)3 in the maintenance and NF-interleukin (IL)6 in the maintenance or even termination of brain-inflammation and fever. Moreover, psychological stressors, such as exposure to a novel environment, leads to increased body core temperature and genomic NF-IL6-activation, suggesting a potential use of NF-IL6-immunohistochemistry as a multimodal brain cell activation marker and a role for NF-IL6 for differential brain activity. In addition, the nutritional status, as reflected by circulating levels of the cytokine-like hormone leptin, influence immune-to-brain communication and age-dependent changes in LPS-induced fever. Overall, transcription factors remain therapeutically important targets for the treatment of brain-inflammation and fever induction during infectious/non-infectious inflammatory and psychological stress. However, the exact physiological role and significance of these transcription factors requires to be further investigated. PMID:26348582

    Full Text Available Background: Increased carotid intima-media thickness (c-IMT is considered a marker of early-onset atherosclerosis and it has been found in obese children and adolescents, but the risk factors associated with this population remain to be elucidated. Objective : To compare and verify the relationship between c-IMT, metabolic profile, inflammatory markers, and cardiorespiratory fitness in obese and non-obese children and adolescents. Method : Thirty-five obese subjects (19 boys and 18 non-obese subjects (9 boys, aged 10-16 years, were included. Anthropometry, body composition, blood pressure, maximal oxygen consumption (VO2max, and basal metabolic rate were evaluated. Serum glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR, blood lipids, C-reactive protein (CRP, and adiponectin were assessed. c-IMT was measured by ultrasound. Results: The results showed that c-IMT, triglycerides, insulin, HOMA-IR, and CRP values were significantly higher in the obese group than in the non-obese group, and high-density lipoprotein cholesterol (HDL-c, adiponectin, and VO2max values were significantly lower in the obese group than in the non-obese group. The c-IMT was directly correlated with body weight, waist circumference, % body fat, and HOMA-IR and inversely correlated with % free fat mass, HDL-c, and VO2max. Conclusions : Our findings show that c-IMT correlates not only with body composition, lipids, insulin resistance, and inflammation but also with low VO2max values in children and adolescents.

    Full Text Available Chronic endobronchial inflammation and bacterial infection are the main causes of morbidity and mortality in cystic fibrosis (CF, an autosomal recessive genetic disorder associated with improper function of chloride channels. Inflammation in CF lung is greatly amplified after Pseudomonas aeruginosa infection. In this study the relationship between P. aeruginosa status and inflammatory markers has been investigated. Seventeen CF children in acute lung exacerbation were examined. CF patients without P. aeruginosa infection were characterized by elevated activity of sputum elastase, reduced response of peripheral blood lymphocytes to PHA and significant resistance to the antiproliferative action of glucocorticoids. These parameters were normalized after antibiotic treatment. The patients with prolonged P. aeruginosa infection demonstrated extremely high levels of elastase activity and elevated amounts of sputum IL-8 and TNF-α. Although antibiotic treatment resulted in clinical improvement, it failed to suppress excessive immune response in the lung. The data indicate that CF patients with prolonged P. aeruginosa need the modified treatment, which should include immunomodulating drugs and protease inhibitors as well as antibacterial therapy.

    Full Text Available Abstract Background Inflammatory breast cancer (IBC is a distinct and aggressive form of locally-advanced breast cancer with high metastatic potential. In Tunisia, IBC is associated with a high death rate. Among the major molecular subtypes, basal breast carcinomas are poorly differentiated, have metastatic potential and poor prognosis, but respond relatively well to chemotherapy. The aim of this study was to determine the distribution of molecular subtypes in IBC and identify factors that may explain the poor prognosis of IBC. Methods To determine breast cancer subtypes we studied by immunohistochemistry the expression of 12 proteins in a series of 91 Tunisian IBC and 541 non-IBC deposited in tissue microarrays. Results We considered infiltrating ductal cases only. We found 33.8% of basal cases in IBC vs 15.9% in non-IBC (p Conclusion Tunisian IBCs are characterized by frequent basal and ERBB2 phenotypes. Surprisingly, luminal IBC also express the basal marker P-cadherin. This profile suggests a specificity that needs further investigation.

    Brown seaweeds such as Ascophyllum nodosum are a rich source of phlorotannins (oligomers and polymers of phloroglucinol units), a class of polyphenols that are unique to Phaeophyceae. At present, there is no information on the bioavailability of seaweed polyphenols and limited evidence on their bioactivity in vivo. Consequently, we investigated the gastrointestinal modifications in vitro of seaweed phlorotannins from A. nodosum and their bioavailability and effect on inflammatory markers in healthy participants. In vitro, some phlorotannin oligomers were identified after digestion and colonic fermentation. In addition, seven metabolites corresponding to in vitro-absorbed metabolites were identified. Urine and plasma samples contained a variety of metabolites attributed to both unconjugated and conjugated metabolites (glucuronides and/or sulphates). In both urine and plasma, the majority of the metabolites were found in samples collected at late time points (6-24 h), suggesting colonic metabolism of high-molecular-weight phlorotannins, with three phlorotannin oligomers (hydroxytrifuhalol A, 7-hydroxyeckol, C-O-C dimer of phloroglucinol) identified in urine samples. A significant increase of the cytokine IL-8 was also observed. Our study shows for the first time that seaweed phlorotannins are metabolised and absorbed, predominantly in the large intestine, and there is a large inter-individual variation in their metabolic profile. Three phlorotannin oligomers present in the capsule are excreted in urine. Our study is the first investigation of the metabolism and bioavailability of seaweed phlorotannins and the role of colonic biotransformation. In addition, IL-8 is a possible target for phlorotannin bioactivity. PMID:26879487

    Full Text Available A randomized controlled clinical trial in 196 obese subjects was performed to examine the effectiveness of body acupuncture on body weight loss, lipid profile and immunogenic and inflammatory markers. 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.

Cardiac protective effects of these compounds against dyslipidemia, hypercoagulability, oxidative stress and inflammation in diabetic mice were examined. Methods Diabetic mice were divided into three groups (15 mice per group: diabetic mice with normal diet, 2% CA treatment, or 2% EA treatment. One group of non-diabetic mice with normal diet was used for comparison. After 12 weeks supplement, mice were sacrificed, and the variation of biomarkers for hypercoagulability, oxidative stress and inflammation in cardiac tissue of diabetic mice were measured. Results The intake of CA or EA significantly increased cardiac content of these compounds, alleviated body weight loss, elevated plasma insulin and decreased plasma glucose levels in diabetic mice (p p p p p p p Conclusion These results support that CA and EA could provide triglyceride-lowering, anti-coagulatory, anti-oxidative, and anti-inflammatory protection in cardiac tissue of diabetic mice. Thus, the supplement of these agents might be helpful for the prevention or attenuation of diabetic cardiomyopathy.

    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: The objective of this study was to determine whether: (a markers of acute inflammation (white cell count, glucose, interleukin-6, C-reactive protein, and fibrinogen are associated with poor outcome after stroke and (b the addition of markers to previously validated prognostic models improves prediction of poor outcome. METHODS AND FINDINGS: We prospectively recruited patients between 2002 and 2005. Clinicians assessed patients and drew blood for inflammatory markers. Patients were followed up by postal questionnaire for poor outcome (a score of>2 on the modified Rankin Scale and death through the General Register Office (Scotland at 6 mo. We performed a systematic review of the literature and meta-analysis of the association between interleukin-6 and poor outcome after stroke to place our study in the context of previous research. We recruited 844 patients; mortality data were available in 844 (100% and functional outcome in 750 (89%. After appropriate adjustment, the odds ratios for the association of markers and poor outcome (comparing the upper and the lower third were interleukin-6, 3.1 (95% CI: 1.9-5.0; C-reactive protein, 1.9 (95% CI: 1.2-3.1; fibrinogen, 1.5 (95% CI: 1.0-2.36; white cell count, 2.1 (95% CI: 1.3-3.4; and glucose 1.3 (95% CI: 0.8-2.1. The results for interleukin-6 were similar to other studies. However, the addition of inflammatory marker levels to validated prognostic models did not materially improve model discrimination, calibration, or reclassification for prediction of poor outcome after stroke. CONCLUSIONS: Raised levels of markers of the acute inflammatory response after stroke are associated with poor outcomes. However, the addition of these markers to a previously validated stroke prognostic model did not improve the prediction of poor outcome. Whether inflammatory markers are useful in prediction of recurrent stroke or other vascular events is a separate question, which requires further study. Please

  1. Markers of subtypes in inflammatory breast cancer studied by immunohistochemistry: Prominent expression of P-cadherin

    International Nuclear Information System (INIS)

    Inflammatory breast cancer (IBC) is a distinct and aggressive form of locally-advanced breast cancer with high metastatic potential. In Tunisia, IBC is associated with a high death rate. Among the major molecular subtypes, basal breast carcinomas are poorly differentiated, have metastatic potential and poor prognosis, but respond relatively well to chemotherapy. The aim of this study was to determine the distribution of molecular subtypes in IBC and identify factors that may explain the poor prognosis of IBC. To determine breast cancer subtypes we studied by immunohistochemistry the expression of 12 proteins in a series of 91 Tunisian IBC and 541 non-IBC deposited in tissue microarrays. We considered infiltrating ductal cases only. We found 33.8% of basal cases in IBC vs 15.9% in non-IBC (p < 0.001), 33.3% of ERBB2-overexpressing cases in IBC vs 14.5% in non-IBC (p < 0.001), and 29.3% of luminal cases in IBC vs 59.9% in non-IBC (p < 0.001). The most differentially-expressed protein between IBCs and non-IBCs was P-cadherin. P-cadherin expression was found in 75.9% of all IBC vs 48.2% of all non-IBC (p < 0.001), 95% of IBC vs 69% of non-IBC (p = 0.02) in basal cases, and 82% of IBC vs 43% of non-IBC (p < 0.001) in luminal cases. Logistic regression determined that the most discriminating markers between IBCs and non-IBCs were P-cadherin (OR = 4.9, p = 0.0019) MIB1 (OR = 3.6, p = 0.001), CK14 (OR = 2.7, p = 0.02), and ERBB2 (OR = 2.3, p = 0.06). Tunisian IBCs are characterized by frequent basal and ERBB2 phenotypes. Surprisingly, luminal IBC also express the basal marker P-cadherin. This profile suggests a specificity that needs further investigation

    Objectives Despite burgeoning literature in middle-aged adults, little is known regarding pro-inflammatory markers (PIMs) among adolescents and young adults with bipolar disorder. Similarly, few prior studies have considered potential confounds when examining the association between PIMs and bipolar disorder characteristics. We therefore examined these topics in the Course and Outcome of Bipolar Youth (COBY) study. Methods Subjects were 123 adolescents and young adults (20.4±3.8 years; range 13.4–28.3 years) in COBY, enrolled between October 2000 and July 2006. DSM-IV diagnoses were determined using the Schedule for Affective Disorders and Schizophrenia for school-aged children (KSADS). Clinical characteristics over the preceding 6 months, including mood, comorbidity and treatment, were evaluated using the Longitudinal Interval Follow-up Evaluation (LIFE). Serum levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, and high-sensitivity C-reactive protein (hsCRP) were assayed. Primary analyses examined the association of PIMs with bipolar disorder characteristics over the preceding 6 months. Results Several lifetime clinical characteristics were significantly associated with PIMs in multivariable analyses, including longer illness duration (p=0.005 for IL-6; p=0.0004 for hsCRP), suicide attempts (p=0.01 for TNF-α), family history of suicide attempts or completion (p=0.01 for hsCRP), self-injurious behavior (p=0.005 for TNF-α), SUD (padolescents and young adults with bipolar disorder. Traction toward validating PIMs as clinically relevant biomarkers in bipolar disorder will require repeated measures of PIMs and incorporation of relevant covariates. PMID:26646032

    We have evaluated the effect of a creatine supplementation protocol upon inflammatory and muscle soreness markers: creatine kinase (CK), lactate dehydrogenase (LDH), prostaglandin E2) (PGE2) and tumor necrosis factor-alpha (TNF-alpha) after running 30km. Runners with previously experience in running marathons, with their personal best between 2.5-3h were supplemented for 5 days prior to the 30km race with 4 doses of 5g of creatine and 15g of maltodextrine per day while the control group received the same amount of maltodextrine. Pre-race blood samples were collected immediately before running the 30km, and 24h after the end of the test (the post-race samples). After the test, athletes from the control group presented an increase in plasma CK (4.4-fold), LDH (43%), PGE2 6.6-fold) and TNF-alpha (2.34-fold) concentrations, indicating a high level of cell injury and inflammation. Creatine supplementation attenuated the changes observed for CK (by 19%), PGE2 and TNF-alpha (by 60.9% and 33.7%, respectively, p<0.05) and abolished the increase in LDH plasma concentration observed after running 30km, The athletes did not present any side effects such as cramping, dehydration or diarrhea, neither during the period of supplementation, nor during the 30km race. All the athletes finished the race in a time equivalent to their personal best +/- 5.8%. These results indicate that creatine supplementation reduced cell damage and inflammation after an exhaustive intense race. PMID:15306159

    Full Text Available Abstract C-Reactive Protein (CRP is an acute phase reactant routinely used as a biomarker to assess either infection or inflammatory processes such as autoimmune diseases. CRP also has demonstrated utility as a predictive marker of future risk of cardiovascular disease. A new method of immunoassay for the detection of C-Reactive Protein has been developed using Resonant Acoustic Profiling™ (RAP™ with comparable sensitivity to a high sensitivity CRP ELISA (hsCRP but with considerable time efficiency (12 minutes turnaround time to result. In one method, standard solutions of CRP (0 to 231 ng/mL or diluted spiked horse serum sample are injected through two sensor channels of a RAP™ biosensor. One contains a surface with sheep antibody to CRP, the other a control surface containing purified Sheep IgG. At the end of a 5-minute injection the initial rate of change in resonant frequency was proportional to CRP concentration. The initial rates of a second sandwich step of anti-CRP binding were also proportional to the sample CRP concentration and provided a more sensitive method for quantification of CRP. The lower limit of detection for the direct assay and the homogenous sandwich assay were both 20 ng/mL whereas for the direct sandwich assay the lower limit was 3 ng/mL. In a step towards a rapid clinical assay, diluted horse blood spiked with human CRP was passed over one sensor channel whilst a reference standard solution at the borderline cardiovascular risk level was passed over the other. A semi-quantities ratio was thus obtained indicative of sample CRP status. Overall, the present study revealed that CRP concentrations in serum that might be expected in both normal and pathological conditions can be detected in a time-efficient, label-free immunoassay with RAP™ detection technology with determined CRP concentrations in close agreement with those determined using a commercially available high sensitivity ELISA.

    Most gallbladder cancer (GBC) cases arise in the context of gallstones, which cause inflammation, but few gallstone patients develop GBC. We explored inflammation/immune-related markers measured in bile and serum in GBC cases compared to gallstone patients to better understand how inflammatory patterns in these two conditions differ. We measured 65 immune-related markers in serum and bile from 41 GBC cases and 127 gallstone patients from Shanghai, China, and calculated age- and sex-adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) for GBC versus gallstones. We then focused on the markers that were significantly elevated in bile and serum to replicate the findings in serum from 35 GBC cases and 31 gallstone controls from Chile. Comparing the highest versus lowest quantile, 15 markers (23%) were elevated in both serum and bile from GBC versus gallstone patients in the Shanghai study (plocal inflammatory process is reflected systemically. Future longitudinal studies are needed to identify the key players in cancer development, which may guide translational efforts to identify individuals at high risk of developing GBC. PMID:27173614

    2015-04-01

    Full Text Available Background - Improvements in congenital heart disease (CHD screening are needed based on the lack of sensitivity of current screening methods and the understanding that the early detection of certain CHDs may improve outcomes. Fetal venous circulation has caught medical attention, and two studies demonstrated that it is feasible to register pulmonary vein flow velocity waveforms (FVWs during early gestation. Meanwhile, the latter study proposed pulmonary vein A-wave reversal as a marker of cardiac anomaly. Methods - We report a series of six consecutive fetuses with confirmed cardiac anomalies that underwent first-trimester screening, including pulmonary vein FVWs, at our center during 2013. CHD was confirmed by late pregnancy echocardiography, and in three cases fetal autopsies were performed. Result/Discussion - The ductus venosus (DV and nuchal translucency (NT predicted 50% of CHD cases, whereas the combination of markers identified 66.6% of CHD cases. When adding pulmonary vein assessment, the rate of detection rose to 83.3%. Total five of six cases of CHD had reversal of pulmonary vein A-wave during early pregnancy. The sixth case with CHD and nonreversal of A-wave was described as right ventricle hypoplasia with type 1 tricuspid atresia and persistent ductus arteriosus. Conclusion This is the first series reporting pulmonary vein end-diastolic reversal as a CHD screening add-on during early pregnancy. The addition of pulmonary vein FVW assessment to the current CHD screening bundle could increase the rate detection of cardiac anomalies. This pilot study suggests that pulmonary vein end-diastolic flow reversal favors detection of left-sided CHD over the right-sided ones.

    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.

    Full Text Available Progressive cardiotoxicity following treatment with doxorubicin-based chemotherapy in patients with non-Hodgkin’s lymphoma (NHL may lead to late onset cardiomyopathy. So, early prediction of toxicity can lead to prevention of heart failure in these patients. The aim of this work was to investigate the role of H-FABP as an early diagnostic marker of anthracycline-induced cardiac toxicity together with brain natriuretic peptide (BNP as an indication of ventricular dysfunction in such patients. Our study was conducted on 40 NHL patients who received 6 cycles of a doxorubicin containing chemotherapy protocol (CHOP, not exceeding the total allowed dose of doxorubicin (500 mg/m2. Ten healthy controls were included in our study. Human heart-type fatty acid binding protein (H-FABP was assessed 24 hours after the first cycle of CHOP. Plasma levels of BNP were estimated both before starting chemotherapy and after the last cycle of CHOP. Resting echocardiography was also performed before and at the end of chemotherapy cycles. The ejection fraction (EF of 8 of our patients decreased below 50% at the end of the sixth cycle. Elevated levels of both H-FABP and BNP were found in all patients wth EF below 50% and both markers showed a positive correlation with each other. We concluded that H-FABP may serve as a reliable early marker for prediction of cardiomyopathy induced by doxorubicin. Thus, in patients with elevated H-FABP, alternative treatment modalities with no cardiac toxicity may be considered in order to prevent subsequent heart failure in these patients.

    Full Text Available Background: Diabetes causes the increased concentration of circulatory cytokines as a result of inflammation. Considering that pomegranate juice (PJ is known to have antioxidant and anti-inflammatory properties, the purpose of this study was to determine the effects of PJ consumption on markers of inflammation in patients with type 2 diabetes (T2D. Materials and Methods: In a randomized, double-blind clinical trial study, 50 patients with T2D (40-65 years old were randomly assigned to one of two groups. Participants in each group received either 250 mL/day PJ or a control beverage for 12 weeks. Biochemical markers including fasting plasma glucose (FPG, insulin and inflammatory markers were assayed on the baseline and follow-up blood samples. Results: In all, 44 patients in two groups were included in the analysis: PJ (n = 22 and placebo (n = 22. After 12 weeks of intervention, in the PJ group, there were 32% and 30% significant decreases in plasma C-reactive protein (hs-CRP and Interlukin-6, respectively (P < 0.05. The mean ± SD plasma interlukin-6 (7.1 ± 5.6 vs. 11.9 ± 14.4 mg/L and hs-CRP (1791 ± 1657 and 1953 ± 1561 ng/mL concentrations in the PJ group were significantly lower than the placebo group after intervention (P < 0.05. Conclusion: PJ consumption by patients with T2D does not affect FPG or the insulin resistance index (HOMA-IR, whereas it does reduce Interlukin-6 and hs-CRP concentrations in plasma. Therefore, PJ consumption may have an anti-inflammatory effect in patients with T2D.

    The objective of the present study was to investigate the effects of combined training without caloric restriction on inflammatory markers in overweight girls. Thirty-three girls (13-17 years) were assigned into overweight training (n = 17) or overweight control (n = 16) groups. Additionally, a normal-weight group (n = 15) was used as control for the baseline values. The combined training programme consisted of six resistance exercises (three sets of 6-10 repetitions at 60-70% 1 RM) followed by 30 min of aerobic exercise (walking/running) at 50-80% VO2peak, performed in the same 60 min session, 3 days/weeks, for 12 weeks. Body composition, dietary intake, aerobic fitness (VO2peak), muscular strength (1 RM), glycaemia, insulinemia, lipid profile and inflammatory markers (C-reactive protein, interleukin-6, tumour necrosis factor-alpha, interleukin-10, leptin, resistin and adiponectin) were measured before and after intervention. There was a significant decrease in body fat (P < 0.01) and increase in fat-free mass (P < 0.01), VO2peak (P < 0.01), 1 RM for leg press (P < 0.01) and bench press (P < 0.01) in the overweight training group. Concomitantly, this group presented significant decreases in serum concentrations of C-reactive protein (P < 0.05) and leptin (P < 0.05), as well as in insulin resistance (P < 0.05) after the experimental period. In conclusion, 12 weeks of combined training without caloric restriction reduced inflammatory markers associated with obesity in overweight girls. PMID:26852885

    Both basic and clinical research indicates that females are more susceptible to stress-related affective disorders than males. One of the mechanisms by which stress induces depression is via inflammatory signaling in the brain. Stress during adolescence, in particular, can also disrupt the activation and continued development of both the hypothalamic–pituitary–adrenal (HPA) and –gonadal (HPG) axes, both of which modulate inflammatory pathways and brain regions involved in affective behavior. ...

    2013-08-01

    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.

    Full Text Available Now pelvic inflammatory disease (PID is one of the most urgent problems in modern gynecology. Pelvic inflammatory diseases (PID have a leading position not only in the structure of gynecological morbidity, but also are the most frequent cause of damage to the reproductive health of women, thereby creating health, social and economic problems. In modern conditions, inflammatory diseases of the genitals are characterized by several features: multifocal inflammatory lesion; the lack of specific clinical symptoms; transformation of clinical finding toward obligated and atypical forms which causes significant difficulties in diagnosis. Latent, obligated, indolent, asymptomatic, subclinical, and in English literature - "dumb, atypical or unrecognized" inflammation is 60% of all PID (V.I. Kulakov, 2005, A.P. Nikonov, 2006, Bezbakh I.V., 2006, Lineva O.I., 2006, Kovalev, L.A., 2010, Sweet R.L., 2009 Serov V.N., 2011. In 2012 European Guideline IUSTI / WHO on keeping patients with pelvic inflammatory disease was published. Unfortunately, conventional methods for routine laboratory studies often have a diagnostic value only in patients with severe clinical manifestations of the disease. Thus, to assess the severity of the inflammatory process only by conventional clinical criteria are currently not possible. Search of diagnostic criteria based on objective indicators, is highly relevant [1], [3].

    Inflammation contributes significantly to cardiac dysfunction. Although the initial phase of inflammation is essential for repair and healing, excessive proinflammatory cytokines are detrimental to the heart. We found that adenine nucleotide translocator isoform-1 (ANT1) protein levels were significantly decreased in the inflamed heart of C57BL/6 mice following cecal ligation and puncture. To understand the molecular mechanisms involved, we performed small-interfering RNA-mediated knockdown o...

  4. Changes in the fecal profile of inflammatory markers after moderate consumption of red wine: a human trial study

    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.

  5. Cardiac-Restricted IGF-1Ea Overexpression Reduces the Early Accumulation of Inflammatory Myeloid Cells and Mediates Expression of Extracellular Matrix Remodelling Genes after Myocardial Infarction

    Full Text Available Strategies to limit damage and improve repair after myocardial infarct remain a major therapeutic goal in cardiology. Our previous studies have shown that constitutive expression of a locally acting insulin-like growth factor-1 Ea (IGF-1Ea propeptide promotes functional restoration after cardiac injury associated with decreased scar formation. In the current study, we investigated the underlying molecular and cellular mechanisms behind the enhanced functional recovery. We observed improved cardiac function in mice overexpressing cardiac-specific IGF-1Ea as early as day 7 after myocardial infarction. Analysis of gene transcription revealed that supplemental IGF-1Ea regulated expression of key metalloproteinases (MMP-2 and MMP-9, their inhibitors (TIMP-1 and TIMP-2, and collagen types (Col 1α1 and Col 1α3 in the first week after injury. Infiltration of inflammatory cells, which direct the remodelling process, was also altered; in particular there was a notable reduction in inflammatory Ly6C+ monocytes at day 3 and an increase in anti-inflammatory CD206+ macrophages at day 7. Taken together, these results indicate that the IGF-1Ea transgene shifts the balance of innate immune cell populations early after infarction, favouring a reduction in inflammatory myeloid cells. This correlates with reduced extracellular matrix remodelling and changes in collagen composition that may confer enhanced scar elasticity and improved cardiac function.

  6. Human embryonic stem cell derived mesenchymal progenitors express cardiac markers but do not form contractile cardiomyocytes.

    Christophe M Raynaud

    Full Text Available Mesenchymal progenitors or stromal cells have shown promise as a therapeutic strategy for a range of diseases including heart failure. In this context, we explored the growth and differentiation potential of mesenchymal progenitors (MPs derived in vitro from human embryonic stem cells (hESCs. Similar to MPs isolated from bone marrow, hESC derived MPs (hESC-MPs efficiently differentiated into archetypical mesenchymal derivatives such as chondrocytes and adipocytes. Upon treatment with 5-Azacytidine or TGF-β1, hESC-MPs modified their morphology and up-regulated expression of key cardiac transcription factors such as NKX2-5, MEF2C, HAND2 and MYOCD. Nevertheless, NKX2-5+ hESC-MP derivatives did not form contractile cardiomyocytes, raising questions concerning the suitability of these cells as a platform for cardiomyocyte replacement therapy. Gene profiling experiments revealed that, although hESC-MP derived cells expressed a suite of cardiac related genes, they lacked the complete repertoire of genes associated with bona fide cardiomyocytes. Our results suggest that whilst agents such as TGF-β1 and 5-Azacytidine can induce expression of cardiac related genes, but treated cells retain a mesenchymal like phenotype.

    Background: Previous studies have reported endothelial dysfunction and inflammatory cytokine in heart failure patients (HF). Objectives: The purpose of this study was to determine the effects of creatine monohydrate and exercise on inflammatory and endothelial dysfunction markers among HF patients. Patients and Methods: One hundred patients were prospectively randomized into two groups: Intervention group which received 5 grams/day creatine monohydrate and exercised for 8 weeks; and control group which did not receive any interventions. Interleukine-6 (IL-6), high sensitivity C reactive protein (hs-CRP), P-selectin, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule 1 (VCAM-1) were measured at the start and end of the study for both groups. Results: In total, 100 patients including 50 controls and 50 intervention group (54% male, mean EF of 34.2 ± 10.5% and 52% male, mean EF of 35.6 ± 12.7%, respectively) were analyzed. The serum levels of hs-CRP and IL-6 increased at the end of the study in the control group compared to the baseline, (7.5 ± 1.5 mg/L vs. 6.9 ± 1.3 mg/L, P 0.05). Conclusions: Combination of creatine monohydrate and exercise attenuated inflammation and endothelial dysfunction markers among heart failure patients.

    A suggestive mechanism behind the association between particulate matter and cardiovascular disease is inflammatory response. Earlier population-based studies investigating the association between particulate matter and inflammatory biological markers, in particular C-reactive protein (CRP), showed inconsistent results. In addition, evidence from the Asian population, in which CRP levels are typically lower than those observed in Western populations, was sparse. We examined the cross-sectional association between short- and long-term exposure to particulate matter and inflammatory markers, including high-sensitivity CRP (hs-CRP) and white blood cell (WBC) count, in a representative population of Japanese community dwellers (NIPPON DATA2010). We analysed data from 2360 participants (1002 men and 1358 women), aged 20 years or older, who resided in 300 randomly selected districts (222 public health centre areas) throughout Japan. We used background concentrations of suspended particulate matter (SPM, defined as particles with a 100% cut-off level at 10 μm aerodynamic diameter) and co-pollutants within the public health centre area. A logistic regression model was applied to estimate odds ratios (ORs) of elevated hs-CRP (> 0.3 mg/dl) or WBC (> 9000/μl). Since smoking is an important confounding factor, we firstly included this in the models, and additionally conducted the analyses after excluding current smokers. The one-month average concentration of SPM was positively associated with hs-CRP (OR per 10 μg/m(3) increase in SPM = 1.42, 95% confidence interval = 1.00-2.04), and high exposure to SPM on the day of blood draw was associated with increased WBC count, after excluding current smokers (OR = 1.13, 1.01-1.28). Similar association patterns were observed for ozone. In conclusion, exposure to particulate matter was associated with inflammatory markers in the general Japanese population. Systemic inflammation may play a role in the link between

    Full Text Available FOXP3+ regulatory T cells (Tregs are critical for preventing intestinal inflammation. However, FOXP3+ T cells are paradoxically increased in the intestines of patients with the inflammatory bowel disease (IBD ulcerative colitis (UC or Crohn's disease (CD. We determined whether these FOXP3+ cells in IBD patients share or lack the phenotype of such cells from patients without IBD.We quantified and characterized FOXP3+ Treg populations, as well as FOXP3- CD4+ T cells, in the lamina propria lymphocytes (LPL of intestine surgically resected from patients with and without IBD, and in the blood of controls or Crohn's patients with or without disease activity.In all samples, a similar fraction of FOXP3+ cells expressed the "natural" Treg (nTreg marker Helios, suggesting that, in IBD, these cells are not entirely "induced" Tregs (iTregs derived from activated effector T cells. Helios+ and Helios- FOXP3+ T cells demonstrated similar expression of maturation markers, activation markers, and inhibitory molecules between IBD patients and controls, while FOXP3- cells paradoxically expressed more of the inhibitory receptors CD39, CTLA4, and PD-1 in inflamed mucosa. Greater expression of activation markers was also seen in both Helios+ and Helios- Tregs, relative to FOXP3- cells, in both IBD patients and controls, indicating that Tregs are effectively activated by antigen in IBD.Extensive immunophenotyping revealed that Helios+ and Helios- mucosal Tregs exist at a similar frequency, and have a similar expression of inhibitory molecules and activation markers in patients with IBD as in healthy controls.

    2015-01-01

    Full Text Available Context: Systemic conditions, especially chronic infections, have a direct impact on the general health and well-being of an individual. Similarly, the long-standing inflammatory changes seen during periodontitis have been associated with the altered diabetic control, preterm, low birth weight infants, and cardiovascular disease. Being a low-grade infection, the signs may not be as severe as seen in other systemic conditions, but they definitely cannot be ignored. Aims: The present study was designed to compare clinical, hematological, and systemic inflammatory markers in patients with chronic periodontitis. Subjects and Methods: A total of 90 chronic periodontitis patients were selected for the present study from the outpatient department of the Department of Periodontology, and the various clinical and hematological parameters were then assessed. Statistical Analysis Used: Z-test was used to compare the probing depth, clinical attachment loss, hematological parameter, and interleukin-6 values between Group A and Group B. Mann-Whitney U-test was used to compare gingival index, plaque index, and bleeding on probing between Group A and Group B. Results: The results of the study were based on the comparison of the clinical, hematological, and systemic inflammatory markers in smokers and nonsmokers with chronic periodontitis and came out to be statistically highly significant. Conclusions: With the resurgence of emphasis on significance of oral diseases related to systemic health, the medical professionals also need to familiarize themselves with the oral cavity and the oral-systemic inter-relationships to treat or reduce the morbidity of the underlying medical condition. Furthermore, the oral health care professionals must reach out to the medical community and the general public to improve patient care through education and communication about the oral health-systemic health link.

    Full Text Available Background. Delayed graft function (DGF remains an important problem after kidney transplantation and reduced long-term graft survival of the transplanted organ. The aim of the present study was to determine if the development of DGF was associated with a specific pattern of inflammatory gene expression in expanded criteria of deceased donor kidney transplantation. Also, we explored the presence of correlations between DGF risk factors and the profile that was found. Methods. Seven days after kidney transplant, a cDNA microarray was performed on biopsies of graft from patients with and without DGF. Data was confirmed by real-time PCR. Correlations were performed between inflammatory gene expression and clinical risk factors. Results. From a total of 84 genes analyzed, 58 genes were upregulated while only 1 gene was downregulated in patients with DGF compared with no DGF (P=0.01. The most relevant genes fold changes observed was IFNA1, IL-10, IL-1F7, IL-1R1, HMOX-1, and TGF-β. The results were confirmed for IFNA1, IL-1R1, HMOX-1 and TGF-β. A correlation was observed between TGF-β, donor age, and preablation creatinine, but not body mass index (BMI. Also, TGF-β showed an association with recipient age, while IFNA1 correlated with recipient BMI. Furthermore, TGF-β, IFNA1 and HMOX-1 correlated with several posttransplant kidney function markers, such as diuresis, ultrasound Doppler, and glycemia. Conclusions. Overall, the present study shows that DGF is associated with inflammatory markers, which are correlated with donor and recipient DGF risk factors.

  18. Relationship of inflammatory markers and pain in patients with head and neck cancer prior to anticancer therapy

    International Nuclear Information System (INIS)

    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

    2011-09-01

    Full Text Available OBJECTIVE: Dialysate concentrations of CA-125 reflect the mesothelial cell mass. In patients with peritoneal dialysis ultrafiltration failure, low concentrations of CA-125 have been demonstrated. Statins have anti-inflammatory properties which may be of value in modulating responses to injury. In this study, the lipid-lowering effect of atorvastatin and its effects on the CA-125 levels were evaluated. MATERIALS and METHODS: The 100 patients included in the study were followed with CRF in the CAPD program. The patients were divided into two groups as those who used atorvastatin (group 1, n=60 and the control group (group 2, n=40. All patients were evaluated before treatment and 6 months later for serum total cholesterol, LDL, HDL, TG, CRP, and peritoneal effluent was analyzed for interleukin-6, and CA-125 levels. RESULTS: In group 1 patients, serum CRP and dialysate IL-6 values decreased and the dialysate CA- 125 level increased (p<0.001, whereas there was no change in the group 2 control patients. CONCLUSION: Atorvastatin use in patients with markers of inflammation caused decreased levels of CRP and IL-6, and the anti-inflammatory effects of statins may have played a role. The increased CA-125 levels in patients in group 1 may also be related to the anti-inflammatory effects in addition to the antihyperlipidemic effects.

    Objective: Vitamin D appears to be involved in regulation of glycemic and inflammatory responses in gestational diabetes. The purpose of this study was to compare the serum levels of 25-hydroxyvitamin D (25(OH)D), inflammatory biomarkers and glycemic profile between gestational diabetes mellitus (GDM) and normal glucose tolerance (NGT) pregnant women. Materials and methods: In this cross-sectional study, fasting serum levels of 25(OH)D, insulin, glucose, HOMA-IR, hs-CRP and TNF-α were measured in 45 GDM and 45 NGT women at week 20-30 gestation whom referred to Reference Medical Laboratory of Ahvaz, Iran in 1394. Results: Serum 25(OH)D levels were significantly lower (p = 0.003 ) in the GDM group compared to the NGT group which remained even after controlling for confounders. Insulin and TNF-α levels were not statistically different between groups (p > 0.05). However, in unadjusted model, HOMA-IR and hs-CRP were significantly different between groups that disappeared in adjusted model. In the GDM group, there was a negative significant correlation between 25 (OH) D and fasting blood sugar (p = 0.009) and pre pregnancy BMI (p vitamin D may be responsible for impairments of some glycemic and inflammatory markers in pregnant women. This is more important in overweight pregnant women. However, further studies with larger sample size are recommended in this regards.

    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.

    Abstract Background Inflammatory breast cancer (IBC) is a distinct and aggressive form of locally-advanced breast cancer with high metastatic potential. In Tunisia, IBC is associated with a high death rate. Among the major molecular subtypes, basal breast carcinomas are poorly differentiated, have metastatic potential and poor prognosis, but respond relatively well to chemotherapy. The aim of this study was to determine the distribution of molecular subtypes in IBC and identify factors that m...

    Establishing the diagnosis of Inflammatory Bowel Disease (IBD) with its two main sub forms Crohn‟s Disease (CD) and Ulcerative colitis (UC) are based on medical history, clinical evaluation, laboratory tests, endoscopy, radiology and histology. However no gold standard exists. The lack of appropriate diagnostic tools leads to delayed and incorrect treatment of IBD patients. A substantial amount of patients diagnosed as CD are later reclassified as UC and opposite. Also the...

    Animal studies and clinical observations suggest that epilepsy is associated with inflammation. Translocator protein (TSPO) (18 kDa), a marker of inflammation, is increased in vitro in surgical samples from patients with temporal lobe epilepsy. TSPO can be measured in the living human brain with PET and the novel radioligand 11C-PBR28. In this study, we sought to determine whether in vivo expression of TSPO is increased ipsilateral to the seizure focus in patients with temporal lobe epilepsy.

    The majority of patients survive after extracorporeal circulation without any clinically apparent deleterious effects. However, disturbances exist in various degrees sometimes, which indicate the harmful effects of cardiopulmonary bypass (CPB) in the body. Several factors during extracorporeal circulation either mechanical dependent (exposure of blood to non-biological area) or mechanical independent (surgical wounds, ischemia and reperfusion, alteration in body temperature, release of endotoxins) have been shown to trigger the inflammatory reaction of the body. The complement activation, the release of cytokines, the leukocyte activation and accumulation as well as the production of several "mediators" such as oxygen free radicals, metabolites of arachidonic acid, platelet activating factors (PAF), nitric acid, and endothelin. The investigation continues today on the three metabolites of lornoxicam (the hydroxylated metabolite and two other metabolites of unknown chemical composition) to search for potential new pharmacological properties and activities.

    We studied hemostatic and inflammatory cardiovascular risk factors (CVRF), and total plasma homocysteine (tHcy) in 26 vegetarians (23 lacto- or ovolactovegetarians and 3 vegans), matched by age, sex and socioeconomic status with omnivorous controls. Vegetarians had significantly lower proportion of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids in plasma lipids, significantly shortened bleeding time, and increased blood platelet count and in vitro platelet function (aggregation and secretion). Plasma levels of all coagulation or fibrinolytic factors and natural inhibitors synthesized in the liver were lower in vegetarians than in controls. Whereas for some factors this decrease was statistically significant (fibrinogen, factor VIIc, antithrombin III, protein S, plasminogen) for the remaining (factors VIIIc, Vc, prothrombin, protein C) a trend in the same direction was found. For hemostatic proteins of predominantly extrahepatic origin (von Willebrand factor. tPA, PAI-1) this tendency was not present. No significant differences in inflammatory proteins (C-reactive protein and alpha1-protease inhibitor) were detected in both groups. tHcy was significantly increased in vegetarians, and correlated only with cobalamin levels. The increased platelet function and tHcy found in vegetarians may counteract the known cardiovascular health benefits of vegetarian diet (VD). PMID:10404767

    Full Text Available OBJECTIVE: Hepcidin, a small peptide hormone synthesized in the liver, plays a central role in the regulation of iron metabolism. In addition, it acts as an intermediary in body defense and inflammation. Our aim in this study was to investigate the relationship of hepsidin levels with inflammation and iron indices in patients on peritoneal dialysis (PD.MATERIAL and METHODS: Nondiabetic PD patients were involved. Primary kidney disease, biochemical parameters, complete blood count, iron, total iron binding capacity (TIBC, ferritin, high sensitive C-reactive protein (hsCRP, fibrinogen, parathormone, interleukin (IL-6 and hepcidin levels were recorded as well as demographic parameters.RESULTS: Twenty-one PD patients (mean age 47.7±12.1 years and 17 healthy volunteers (mean age 54.0±7.2 years were involved. HepCidin levels were higher in the PD group (148.2±35.0 vs. 93.8±21.9; p<0.001. There was a positive correlation of hepcidin with urea, creatinine, phosphorus, ferritin, fibrinogen, IL-6 and parathormone; and a negative correlation with albumin, transaminases, calcium, TIBC, GFR, hemoglobin and hematocrit levels.CONCLUSION: Hepcidin levels increase with deepening anemia and show a positive correlation with inflammatory markers. Theurapeutic interventions regarding the effects of hepcidin on inflammatory status may play a role in the treatment of anemia due to inflammation. It may be beneficial to measure hepcidin levels together with ferritin, especially in patients with functional iron defficiency.

    In recent years, expanded data have demonstrated the association between increased inflammatory markers and risk of adverse cardiovascular events in patients undergoing percutaneous coronary intervention (PCI) with stent implantation. Particularly, several studies have demonstrated association between increased C-reactive protein (CRP) level and various risk factors of cardiovascular diseases and their complications. The role of CRP in predicting restenosis after implantation of bare metal stents has been proven, but its role in predicting drug-eluting stents restenosis is still unproved. Significant association between increased white blood cells count and risk of development and severity of coronary artery disease and as well as poor prognosis after PCI has also been demonstrated. But erythrocyte sedimentation rate has been studied insufficiently in this regard. According to some studies, including those conducted in our institute, one can suggest an association between eosinophilic inflammatory response, progression of coronary atherosclerosis, and drug-eluting stents restenosis. Identification of factors affecting prognosis of patients with coronary heart disease after PCI will allow determining further strategy of patient management. PMID:27125112

    Full Text Available Obesity is a worldwide epidemic that increases the risk of several well-known co-morbidities. There is a complicated relationship between adipokines and low-grade inflammation in obesity and cardiovascular disease (CVD. Physical activity practices have beneficial health effects on obesity and related disorders such as hypertension and dyslipidemia. We investigated the effects of 6 and 12 months of moderate physical training on the levels of adipokines and CVD markers in normal weight, overweight and obese volunteers. The 143 participants were followed up at baseline and after six and twelfth months of moderate regular exercise, 2 times a week, for 12 months. The volunteers were distributed into 3 groups: Normal Weight Group (NWG,, Overweight Group (OVG and Obese Group (OBG. We evaluated blood pressure, resting heart rate, anthropometric parameters, body composition, fitness capacity (VO2max and isometric back strength, cardiovascular markers (CRP, total cholesterol, LDL-c, HDL-c, homocysteine and adipokine levels (leptin, adiponectin, resistin, IL-6 and TNF-alpha. There were no significant changes in anthropometric parameters and body composition in any of the groups following 6 and 12 months of exercise training. Leptin, IL-6 levels and systolic blood pressure were significantly elevated in OBG before the training. Regular exercise decreased HDL-c, leptin, adiponectin and resistin levels and diastolic blood pressure in OVG. In OBG, exercise diminished HDL-c, homocysteine, leptin, resistin, IL-6, adiponectin. Moderate exercise had no effect on the body composition; however, exercise did promote beneficial effects on the low-grade inflammatory state and CVD clinical markers in overweight and obese individuals.

    Acute rejection of the transplanted lung is a clinical problem, since it decreases graft survival and predisposes the patient to chronic rejection and obliterative bronchiolitis (OB). In an earlier study, we had indications that eosinophil cationic protein (ECP) from activated eosinophils and hyaluronan (HYA) from fibroblasts were associated with acute pulmonary rejection. This prospective longitudinal study was designed to investigate whether molecules from activated inflammatory cells in bronchoalveolar lavage (BAL) fluid could serve as clinically useful diagnostic markers for acute rejection. BAL fluid from 138 bronchoscopies performed in 10 single lung, four bilateral lung and five heart-lung transplant recipients were analysed. Nine patients were studied for a period of more than 1 yr (mean 13.4 months) after surgery. Differential cell counts were made from the BAL fluid. ECP, myeloperoxidase (MPO), HYA and interleukin-8 (IL-8) were used as indirect markers for activation and attraction of eosinophils, neutrophils and fibroblasts, respectively. Fifty four episodes of acute rejection were diagnosed. Two patients developed OB. Nine episodes of bacterial infection, 13 episodes of cytomegalovirus (CMV) pneumonitis, three of Pneumocystis carinii infection and one of respiratory syncytial virus (RSV) infection were diagnosed. The mean levels of ECP, MPO, HYA and IL-8 were all higher during rejection episodes, but differences were not statistically significant compared to no rejection, when the confounding factors of time, concomitant infection, and repeated measures in the same individual had been accounted for. We could not confirm that measurements of eosinophil cationic protein, myeloperoxidase, hyaluronan and interleukin-8 in bronchoalveolar lavage fluid can be used as diagnostic markers for acute rejection in the postoperative follow-up of lung transplant recipients.

    Full Text Available BACKGROUND: Early predictors for the development of stroke-associated infection may identify patients at high risk and reduce post-stroke infection and mortality. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

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

    2015-11-01

    Full Text Available Background: Heart failure (HF, often referred to as chronic heart failure (CHF, occurs when the heart is unable to pump sufficiently to maintain blood flow to meet the bodys needs. Patients with HF are characterized by systemic inflammation, as evident by raised circulating levels of several inflammatory cytokines with increasing levels according to the degree of disease severity. Inflammation occurs in the vasculature as a response to injury, lipid peroxidation, and perhaps infection. Inflammation can be a significant contributor in the pathophysiology of HF. Antioxidants may slow the progression of HF because of their ability to inhibit damaging inflammatory processes. The purpose of this study was to test a dietary intervention in patients with HF to assess the effect of dietary lycopene on biomarkers of inflammation. Methods: Sixty participants with HF were randomly assigned to 1 of 2 groups: lycopene intervention and non-intervention. The lycopene intervention group received 27.212 mg of lycopene intake per day by drinking 1 serving (243 gm of tomato soup for 30 days. We obtained serum lycopene, and C-reactive protein (CRP, to determine the impact of the intervention. Results: Plasma lycopene levels increased in the intervention group compared with the usual group (0.50 and micro;mol/L to 0.75 and micro;mol/L, P = 0.002; 0.55 and micro;mol/L to 0.57 and micro;mol/L. C-reactive protein levels decreased significantly in the intervention group in both women and men. The pre-intervention and post-intervention CRP level for women was 15.37 +/- 1.46 mg/dL and 8.32 +/- 1.11 mg/dl respectively and for men was 15.05 +/- 2.58 mg/dL and 8.14 +/- 1.49 mg/dL respectively. Conclusions: These findings suggest that the antioxidants in a 30-day intervention of tomato soup significantly decreases CRP levels in a sample of female and male patients with HF.

  7. Hypothyroidism and its rapid correction alter cardiac remodeling.

    Directory of Open Access Journals (Sweden)

    Georges Hajje

    Full Text Available The cardiovascular effects of mild and overt thyroid disease include a vast array of pathological changes. As well, thyroid replacement therapy has been suggested for preserving cardiac function. However, the influence of thyroid hormones on cardiac remodeling has not been thoroughly investigated at the molecular and cellular levels. The purpose of this paper is to study the effect of hypothyroidism and thyroid replacement therapy on cardiac alterations. Thirty Wistar rats were divided into 2 groups: a control (n = 10 group and a group treated with 6-propyl-2-thiouracil (PTU (n = 20 to induce hypothyroidism. Ten of the 20 rats in the PTU group were then treated with L-thyroxine to quickly re-establish euthyroidism. The serum levels of inflammatory markers, such as C-reactive protein (CRP, tumor necrosis factor alpha (TNF-α, interleukin 6 (IL6 and pro-fibrotic transforming growth factor beta 1 (TGF-β1, were significantly increased in hypothyroid rats; elevations in cardiac stress markers, brain natriuretic peptide (BNP and cardiac troponin T (cTnT were also noted. The expressions of cardiac remodeling genes were induced in hypothyroid rats in parallel with the development of fibrosis, and a decline in cardiac function with chamber dilation was measured by echocardiography. Rapidly reversing the hypothyroidism and restoring the euthyroid state improved cardiac function with a decrease in the levels of cardiac remodeling markers. However, this change further increased the levels of inflammatory and fibrotic markers in the plasma and heart and led to myocardial cellular infiltration. In conclusion, we showed that hypothyroidism is related to cardiac function decline, fibrosis and inflammation; most importantly, the rapid correction of hypothyroidism led to cardiac injuries. Our results might offer new insights for the management of hypothyroidism-induced heart disease.

Thus, a study of immunostaining for liver insulin, adiponectin, tumor necrosis factor alpha (TNF-α, and inducible nitric oxide synthase (iNOS receptors was conducted.Objective:To expand the knowledge about the pathophysiological and molecular mechanisms underlying the experimental model of steatohepatitis in rats fed a high-fat diet.Method:Twenty Wistar rats were divided into two groups: G1 (control, fed a standard diet, and G2 (fed a high-fat diet containing 58% of energy derived from fat, 18% from protein and 24% from carbohydrate. After eight weeks the animals were sacrificed. Blood glucose, insulin, total cholesterol, high-density lipoprotein (HDL, the very low-density lipoproteins (VLDL, triglycerides, aspartate aminotransferase (AST, alanine aminotransferase (ALT, alkaline phosphatase (ALP and gamma-glutamyl transferase (GGT were determined. The liver tissue was submitted to histopathological analysis, using a NAS score. In immunohistochemistry, we studied the expression of the insulin receptor, adiponectin, TNF-α and iNOS by tissue microarray method.Results and conclusion:There was marked cytoplasmic immunostaining for TNF-α and iNOS mediators in the group on a fat diet. Regarding insulin and adiponectin molecular markers, a reduction of cytoplasmic immunoreactivity of these antigens was observed in the group on a fat diet, reflecting, respectively, the state of hepatocellular inflammation (steatohepatitis and insulin resistance in this experimental model of fat liver disease.

    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.

    microglia in vitro. To extend our in vitro findings in vivo, we investigated whether administration of the peroxisomal proliferator-activated receptor (PPAR)ä agonist, GW0742, prevented radiation-induced brain injury in C57Bl/6 WT mice. Our data demonstrate that GW0742 prevented the radiation-induced increase in the number of activated microglia (CD68+ cells) in wild-type (WT) mice 1 week following 10 Gy WBI. Furthermore, GW0742 inhibited the WBI-induced increase in IL-1β message levels and ERK phosphorylation observed 3 h post-irradiation. In contrast, GW0742 administration failed to modulate the radiation-induced decrease in hippocampal neurogenesis (NeuN+/BrdU+ cells) determined 2 months after irradiation, or mitigate hippocampal-dependent spatial memory impairment observed 3 months post-irradiation using the Barnes Maze task. We used PPARō knockout (KO) mice to examine if the effects of GW0742 are PPARō-dependent. Unexpectedly, PPARō KO mice exhibited a differential response following WBI compared to WT mice; therefore, we were unable to make mechanistic conclusions about GW0742. KO mice do not exhibit a WBI-induced increase in activated microglia; however, they appeared to display a pronounced astrocytic response. In particular, PPARō KO but not WT mice displayed increased GFAP message levels 2 months after WBI. Additionally, the number of GFAP+ cells was reduced significantly in the WT mice 2 months after WBI, but it was not in the PPARō KO mice. These results demonstrate that: i) GW0742 prevents the radiation-induced increase in microglial activation and inflammatory markers, and ii) WT and PPARō KO mice have a differential response to WBI.

    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.

    Full Text Available Objective. to evaluate changes in the expression of tumor necrosis factor-α in patients with rheumatoid arthritis submitted to phototherapy. Materials and methods. This was an open label study, enrolling ten patients. The phototherapy scheme within a range of 425 to 650 nm, 11.33 Joules/cm2, 30 cm above the chest was as follows: a 45-min daily sessions from Monday to Friday for 2 to 3 months; b three, 45min weekly sessions for 1 to 2 months; c twice weekly 45-min sessions for 1 to 2 months, and d one weekly session for 1 to 2 months until completion. Erythrocyte sedimentation rate, C-reactive protein and rheumatoid factor were measured in peripheral blood and tumor necrosis factor-α, interleukin-1β, and interleukin-10 in leukocytes by quantitative real-time Reverse transcriptase-Polymerase chain reaction. In all the patients the next indexes: Karnofsky scale, Rheumatoid Arthritis-specific quality of life instrument, Steinbrocker Functional Capacity Rating and the Visual Analog Scale were evaluated. Results. Erythrocyte sedimentation rate, C-reactive protein, and rheumatoid factor declined notoriously after the indicated sessions. In gene expression, there was a tendency in tumor necrosis factor-α to decrease after 1 month, from 24.5±11.4 to 18±9.2 relative units, without reaching a significant statistical difference. The four tested indexes showed improvement. Conclusion. Phototherapy appears to be a plausible complementary option to reduce the inflammatory component in rheumatoid arthritis.

    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.

    The objective of the present study was to examine the genetically determined differences in the natriuretic peptide receptor-A (NPRA) gene (Npr1) copies affecting the expression of cardiac hypertrophic markers, proinflammatory mediators, and matrix metalloproteinases (MMPs) in a gene-dose-dependent manner. We determined whether stimulation of Npr1 by all-trans retinoic acid (RA) and histone deacetylase (HDAC) inhibitor sodium butyric acid (SB) suppress the expression of cardiac disease markers. In the present study, we utilized Npr1 gene-disrupted heterozygous (Npr1(+/-), 1-copy), wild-type (Npr1(+/+), 2-copy), gene-duplicated (Npr1(++/+), 3-copy) mice, which were treated intraperitoneally with RA, SB, and a combination of RA/SB, a hybrid drug (HB) for 2 wk. Untreated 1-copy mice showed significantly increased heart weight-body weight (HW/BW) ratio, blood pressure, hypertrophic markers, including beta-myosin heavy chain (β-MHC) and proto-oncogenes (c-fos and c-jun), proinflammatory mediator nuclear factor kappa B (NF-κB), and MMPs (MMP-2, MMP-9) compared with 2-copy and 3-copy mice. The heterozygous (haplotype) 1-copy mice treated with RA, SB, or HB, exhibited significant reduction in the expression of β-MHC, c-fos, c-jun, NF-κB, MMP-2, and MMP-9. In drug-treated animals, the activity and expression levels of HDAC were significantly reduced and histone acetyltransferase activity and expression levels were increased. The drug treatments significantly increased the fractional shortening and reduced the systolic and diastolic parameters of the Npr1(+/-) mice hearts. Together, the present results demonstrate that a decreased Npr1 copy number enhanced the expression of hypertrophic markers, proinflammatory mediators, and MMPs, whereas an increased Npr1 repressed the cardiac disease markers in a gene-dose-dependent manner.

    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.

    Full Text Available Abstract Background Serum sialic acid and C reactive protein are the markers for inflammation. The main objective of this study was to determine the sialic acid level in Caribbean type 2 diabetic patients with and without microvascular complications and its relationship with metabolic and anthropometric variables. Research design and methods The Caribbean subjects aged 15–60 years with type 2 diabetes were recruited for the study. Fasting venous blood samples were collected from 162 subjects of which 44 were healthy individuals, 44 were of type 2 diabetes, 44 were of type 2 diabetes with nephropathy and 30 were of diabetes with retinopathy. Simultaneously urine samples were also collected from each of the subjects. All the blood samples were processed for lipid profile, glucose, HbA1C, C-reactive protein and sialic acid. The urine samples were analysed for sialic acid and microalbumin. Results Serum sialic acid concentrations were significantly higher among diabetic subjects (66.0 ± 11.7 mg % as compared to controls (55.2 ± 8.3 mg %. There was a significantly increasing trend of serum sialic acid with severity of nephropathy (71.6 ± 23.6 mg % and degree of urinary albumin excretion (794.3 ± 805.9. The diabetic retinopathy patients also demonstrated significantly higher values of serum sialic acid (77.9 ± 29.0 and urine microalbumin (351.1 ± 559.9. Elevated serum sialic acid microalbumin concentrations were associated with cardiovascular risk factors such as hypertension, increased waist to hip ratios. (P Conclusion The increased serum sialic acid and microalbumin were strongly related to the presence of microvascular complications like diabetic nephropathy and diabetic retinopathy and cardiovascular risk factors like hypertension and waist to hip ratios in Caribbean type-2 diabetic patients. The serum sialic acid may be used as an inflammatory marker and possible indicator of microvascular complications in type-2 diabetic patients.

    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 Parkinson´s disease (PD is a neurodegenerative disorder that is characterised by loss of midbrain dopaminergic (mDA neurons in the substantia nigra (SN. Microglia-mediated neuroinflammation has been described as a common hallmark of PD and is believed to further trigger the progression of neurodegenerative events. Injections of 6-hydroxydopamine (6-OHDA are widely used to induce degeneration of mDA neurons in rodents as an attempt to mimic PD and to study neurodegeneration, neuroinflammation as well as potential therapeutic approaches. In the present study, we addressed microglia and astroglia reactivity in the SN and the caudatoputamen (CPu after 6-OHDA injections into the medial forebrain bundle (MFB, and further analysed the temporal and spatial expression patterns of pro-inflammatory and anti-inflammatory markers in this mouse model of PD. We provide evidence that activated microglia as well as neurons in the lesioned SN and CPu express Tgfβ1, which overlaps with the downregulation of pro-inflammatory markers Tnfα, and iNos, and upregulation of anti-inflammatory markers Ym1 and Arg1. Taken together, the data presented in this study suggest an important role for Tgfβ1 as a lesion-associated factor that might be involved in regulating microglia activation states in the 6-OHDA mouse model of PD in order to prevent degeneration of uninjured neurons by microglia-mediated release of neurotoxic factors such as Tnfα and nitric oxide (NO.

    Full Text Available Objectives. We sought to assess the comparative value of inflammatory markers on the occurrence of left ventricular systolic dysfunction (LVSD after an acute coronary syndrome (ACS. Methods. During 2006–2008, 760 patients with an ACS were enrolled. C-reactive protein (CRP and white blood cell (WBC count were measured during the first 12 hours of hospital admission. Results. CRP levels and WBC count were significantly higher in those who developed LVSD compared to those who did not. The analysis revealed that a 10 mg/dL increase of CRP levels and a 1000/L increase in WBC are associated with a 6% and a 7% increase in the likelihood of developing LVSD, respectively. Furthermore, WBC count at entry and CRP have almost the same predictive value for development of LVSD after an ACS (2=0.109 versus 2=0.093. Conclusions. Serum CRP levels and WBC count at entry are almost equally powerful independent predictors of LVSD, after an ACS.

  2. Epigenetic regulation of cardiac progenitor cells marker c-kit by stromal cell derived factor-1α.

    Zhongpu Chen

    Full Text Available BACKGROUND: Cardiac progenitor cells (CPCs have been proven suitable for stem cell therapy after myocardial infarction, especially c-kit(+CPCs. CPCs marker c-kit and its ligand, the stem cell factor (SCF, are linked as c-kit/SCF axis, which is associated with the functions of proliferation and differentiation. In our previous study, we found that stromal cell-derived factor-1α (SDF-1α could enhance the expression of c-kit. However, the mechanism is unknown. METHODS AND RESULTS: CPCs were isolated from adult mouse hearts, c-kit(+ and c-kit(- CPCs were separated by magnetic beads. The cells were cultured with SDF-1α and CXCR4-selective antagonist AMD3100, and c-kit expression was measured by qPCR and Western blotting. Results showed that SDF-1α could enhance c-kit expression of c-kit(+CPCs, made c-kit(-CPCs expressing c-kit, and AMD3100 could inhibit the function of SDF-1α. After the intervention of SDF-1α and AMD3100, proliferation and migration of CPCs were measured by CCK-8 and transwell assay. Results showed that SDF-1α could enhance the proliferation and migration of both c-kit(+ and c-kit(- CPCs, and AMD3100 could inhibit these functions. DNA methyltransferase (DNMT mRNA were measured by qPCR, DNMT activity was measured using the DNMT activity assay kit, and DNA methylation was analyzed using Sequenom's MassARRAY platform, after the CPCs were cultured with SDF-1α. The results showed that SDF-1α stimulation inhibited the expression of DNMT1 and DNMT3β, which are critical for the maintenance of regional DNA methylation. Global DNMT activity was also inhibited by SDF-1α. Lastly, SDF-1α treatment led to significant demethylation in both c-kit(+ and c-kit(- CPCs. CONCLUSIONS: SDF-1α combined with CXCR4 could up-regulate c-kit expression of c-kit(+CPCs and make c-kit(-CPCs expressing c-kit, which result in the CPCs proliferation and migration ability improvement, through the inhibition of DNMT1 and DNMT3β expression and global DNMT

The aim of this research was to examine the effect of full-mouth scaling and root planing on the reduction of periodontal disease in children with congenital heart disease. In this study, treatments were related to clinical periodontal parameters and also to blood ones, such as lipid profile and inflammatory markers. The patients were divided into two groups: group 1 (n=17, scaling and root planing; and group 2 (n=16, full-mouth scaling and root planing. The results showed a significant improvement in clinical periodontal parameters (P<0.05 in both groups. Considering lipid parameters, total cholesterol, triglycerides, and very-low-density lipoprotein parameters showed significant improvement (P<0.05. There was also an improvement in C-reactive protein (ultrasensitive in the group treated with scaling and root planing (P<0.05. Fibrinogen and interleukin-6 parameters improved (P<0.05 in both groups. We suggest that both periodontal treatments were effective in children with congenital heart disease, though neither demonstrated superiority.

    Current epidemiological studies suggest that crystalline silica exposure is associated with an increased risk of cardiovascular and renal disease; however, the potential pathological damage of the heart and kidney and its underlying mechanisms have not been completely elucidated. This study tried to investigate the silica-induced inflammatory and fibrotic changes in the heart and kidney and evaluate the role of interleukin (IL)-1 beta (β) in silica-induced cardiac and renal damage. In this study, a silica-exposed model was generated by intratracheally instilling silica dust in mice. The anti-IL-1β monoclonal antibody (mAb) was used to neutralise IL-1β in the pulmonary alveolus and serum. The real-time PCR studies showed that (1) inhalational silica induced inflammatory responses in the heart and kidney by elevated mRNA levels of TNF-α, IL-6 and MCP-1; (2) early fibrotic responses in the heart were observed as elevated mRNA levels of collagen I and fibronectin. What is more, fibrosis of the kidney was demonstrated by pathological results and significantly increased mRNA levels of TGF-β, collagen I, collagen III and fibronectin. Further studies showed that usage of anti-IL-1β mAb decreased the inflammatory response of the heart and kidney induced by inhalational silica and also attenuated fibrosis in the mouse kidney. In conclusion, this study found that inhaled silica induced inflammatory and early fibrotic responses in the mouse heart and inflammatory response and fibrosis in the mouse kidney. Neutralisation of IL-1β attenuated the silica-induced inflammatory response of the heart and kidney and decreased fibrosis in the mouse kidney. PMID:25388157

    Yagahira E Castro-Sesquen

    Full Text Available We studied cell death by apoptosis and necrosis in cardiac remodeling produced by Trypanosoma cruzi infection. In addition, we evaluated collagen I, III, IV (CI, CIII and CIV deposition in cardiac tissue, and their relationship with serum levels of procollagen type I carboxy-terminal propeptide (PICP and procollagen type III amino-terminal propeptide (PIIINP. Eight infected and two uninfected guinea pigs were necropsied at seven time points up to one year post-infection. Cell death by necrosis and apoptosis was determined by histopathological observation and terminal deoxynucleotidyl transferase dUTP nick end labeling, respectively. Deposition of cardiac collagen types was determined by immunohistochemistry and serum levels of PICP, PIIINP, and anti-T. cruzi IgG1 and IgG2 by ELISA. IgG2 (Th1 response predominated throughout the course of infection; IgG1 (Th2 response was detected during the chronic phase. Cardiac cell death by necrosis predominated over apoptosis during the acute phase; during the chronic phase, both apoptosis and necrosis were observed in cardiac cells. Apoptosis was also observed in lymphocytes, endothelial cells and epicardial adipose tissue, especially in the chronic phase. Cardiac levels of CI, CIII, CIV increased progressively, but the highest levels were seen in the chronic phase and were primarily due to increase in CIII and CIV. High serum levels of PICP and PIIINP were observed throughout the infection, and increased levels of both biomarkers were associated with cardiac fibrosis (p = 0.002 and p = 0.038, respectively. These results confirm the role of apoptosis in cell loss mainly during the chronic phase and the utility of PICP and PIIINP as biomarkers of fibrosis in cardiac remodeling during T. cruzi infection.

    Industrially produced partially hydrogenated vegetable fat (PHVF) contains trans fatty acids (TFA) mostly comprising elaidic acid (EA, 18:1∆9t). Though, the harmful effects of TFA on health have been repeatedly publicized, the fat containing TFA have been continued to be used as a cooking medium in many regions of the world. The adverse effects of PHVF on oxidative stress and inflammatory markers and the possible ameliorative action of rice bran oil (RBO) on these markers were evaluated. Weaning rats were fed a AIN-93 purified diet supplemented with the following lipids: groundnut oil (GNO, 10 wt%), PHVF (10 wt%), RBO (10 wt%), PHVF blended with RBO at 2.5, 5.0 and 7.5 wt% levels. The final concentration of the lipids in the diet was maintained at 10 wt%. Rats were fed these diets for 60 days. They were sacrificed and analyzed for oxidative stress and inflammatory markers. The rats fed PHVF showed lower levels of lipid peroxidation and hepatic antioxidant enzymes. The rats fed PHVF-containing diets showed enhanced levels of interleukin-1β, C-reactive proteins and also showed enhanced levels of paw inflammation when injected with carrageenan as compared to rats given GNO, RBO or PHVF blended with incremental amounts of RBO. The macrophages from rats fed diet containing PHVF showed up-regulation in the expressions of cytosolic phospholipase A2 (cPLA2), nuclear factor-κB p65, toll like receptor (TLR)-2, TLR-4 and down-regulation in the expressions of peroxisome proliferator activated receptor gamma (PPAR)γ, adiponectin receptor (AdipoR)-1 and AdipoR-2 when compared to rats fed diet containing GNO, RBO and PHVF blended with RBO. It was concluded that dietary PHVF enhance pro-inflammatory markers which can be reduced by judiciously blending PHVF with RBO. PMID:26939679

  10. Cardiac Glycosides Inhibit LPS-induced Activation of Pro-inflammatory Cytokines in Whole Blood through an NF-kappa-B-dependent Mechanism

    Full Text Available Summary: The process of hemodialysis (HD produces a pro-inflammatory state that can lead to an increased risk for cardiovascular disease. In part, this is the result of activation of the pro-inflammatory transcription factor NF-B in response to uremia as well as in response to HD itself, which not only involves exposure of blood leukocytes to abnormal surfaces but also potentially to any bacterial contamination associated with HD. Previously, we used lipopolysaccharide (LPS to activate isolated peripheral blood mononuclear cells (PBMC, as a model of HD-induced stress, and demonstrated that specific natural products that are known to inhibit the activation of NF-B exhibited a broad anti-inflammatory activity. These natural products, however, were not effective when whole blood was used. In the present study, a natural product library (TimTec NPL480 was screened, using whole blood, for the abilities of these natural products to protect against LPS-induced expression and secretion of the pro-inflammatory cytokines TNF, IL-1 and IL-6. We report here that the cardiac glycosides strophanthidin, ouabain, proscillaridin A, digoxin, digitoxin and lanatoside C are effective natural products that limit the development of a pro-inflammatory state by preventing the activation of these pro-inflammatory signals. These active natural products also inhibited the stress-induced activation of NF-B in a reporter assay, suggesting that inhibition of NF-kappa-B is at least partly the mechanism by which these natural products protect whole blood leukocytes from activation by LPS. Industrial relevance: Media for hemodialysis is used millions of times annually for patients with end stage renal disease, each use representing a potential pro-inflammatory insult. It would be useful to have a drug that could be added to the media which would protect blood leukocytes from any pro-inflammatory activation that may accompany the dialysis procedure. A natural

    Full Text Available Aim. To study the effect of treatment with inhaled nitric oxide (iNO on the clinical status of patients with idiopathic pulmonary hypertension (IPH, and the profile of proinflammatory cytokines in peripheral blood. Material and methods. Patients with IPH (n=48 were included into the study. Evaluation of the IPH functional class (FC, the 6-minute walk test (6MWT with the assessment of the Borg index, echocardiography , laboratory tests [blood count, evaluation of high-sensitivity C-reactive protein (hsCRP, interleukins (IL, interferon-γ (INFγ, tumor necrosis factor a (TNFa, macrophage inflammatory protein a (MIP1 a, soluble adhesion molecules (sICAM-1, sVCAM-1 in peripheral blood] were performed at baseline and on day 21 of iNO therapy course. The iNO course 40 ppm during 5 hours a day for 21 days was carried out additionally to the standard IPH therapy under the toxicity control by the PrinterNOx (England. Results. Increase in exercise tolerance, improvement of IPH FC (from 3.35±0.52 to 2.71±0.56; p=0.008, reduction in systolic pulmonary artery pressure (SPAP by Doppler echocardiography (from 96.23±23.65 to 82.36±20.92 mmHg; p<0.05 were found in IPH patients as a result of iNo therapy. The significance of inflammation in IPH pathogenesis was confirmed due to assessment of the initial levels of proinflammatory cytokines. iNO therapy resulted in significant decrease in proinflammatory cytokines-IL-1β, IL-6, IL-8, TNFa levels. iNO induced significant dynamics of IL-1β and sVCAM in patients with IPH FC II. It reduced IL-8 and TNFa and increase INFγ (p<0.05 in patients with IPH FC III-IV. Changes in IL-1β and sVCAM levels (ΔIL-1β and ΔsVCAM by the 21 day of iNO therapy in comparison with these at baseline correlated with ΔSPAP , and ΔIL-6 correlated with ΔFC and Δ6MWT distance (30.5 [21.0; 53.0] m; p<0.001. This allows considering these indicators as markers of iNO treatment efficacy. Conclusions. 21-day iNO therapy in IPH patients

    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.

    Several studies have shown that acute fluoride (F(-)) exposure impairs cardiac function, but the molecular mechanism is not clear. In order to study this, male Wistar rats were treated with single oral doses of 45 and 90 mg/kg F(-) for 24 h. A significant accumulation of F(-) was found in the serum and myocardium of experimental rats. F(-) treatment causes myocardial necrosis as evident from increased levels of myocardial troponin I, creatine kinase, lactate dehydrogenase and aspartate transaminase. In addition, F(-) induces myocardial oxidative stress via increased reactive oxygen species, lipid peroxidation, protein carbonyl content and nitrate levels along with decreased in the levels of enzymatic (superoxide dismutase 2, catalase, glutathione peroxidase and glutathione s transferase pi class) and non-enzymatic (reduced glutathione) antioxidants. Notably, F(-) triggers myocardial apoptosis through altered Bax/Bcl2 ratio and increased cytochrome c, caspase 3p20 and terminal deoxynucleotidyl transferase dUTP nick end labeled positive cells. An increased cardiac expression of Nox4 and p38α MAPK in F(-) treated rats indicates the oxidative and apoptotic damage. Moreover, ultra-structural changes, histopathological and luxol fast blue staining demonstrates the degree of myocardial damage at subcellular level. Taken together, these findings reveal that acute F(-) exposure causes cardiac impairment by altering the expression of oxidative stress, apoptosis and necrotic markers. PMID:26455266

  15. Detraining differentially preserved beneficial effects of exercise on hypertension: effects on blood pressure, cardiac function, brain inflammatory cytokines and oxidative stress.

    Full Text Available AIMS: This study sought to investigate the effects of physical detraining on blood pressure (BP and cardiac morphology and function in hypertension, and on pro- and anti-inflammatory cytokines (PICs and AIC and oxidative stress within the brain of hypertensive rats. METHODS AND RESULTS: Hypertension was induced in male Sprague-Dawley rats by delivering AngiotensinII for 42 days using implanted osmotic minipumps. Rats were randomized into sedentary, trained, and detrained groups. Trained rats underwent moderate-intensity exercise (ExT for 42 days, whereas, detrained groups underwent 28 days of exercise followed by 14 days of detraining. BP and cardiac function were evaluated by radio-telemetry and echocardiography, respectively. At the end, the paraventricular nucleus (PVN was analyzed by Real-time RT-PCR and Western blot. ExT in AngII-infused rats caused delayed progression of hypertension, reduced cardiac hypertrophy, and improved diastolic function. These results were associated with significantly reduced PICs, increased AIC (interleukin (IL-10, and attenuated oxidative stress in the PVN. Detraining did not abolish the exercise-induced attenuation in MAP in hypertensive rats; however, detraining failed to completely preserve exercise-mediated improvement in cardiac hypertrophy and function. Additionally, detraining did not reverse exercise-induced improvement in PICs in the PVN of hypertensive rats; however, the improvements in IL-10 were abolished. CONCLUSION: These results indicate that although 2 weeks of detraining is not long enough to completely abolish the beneficial effects of regular exercise, continuing cessation of exercise may lead to detrimental effects.

    Monocytes are mediators of the inflammatory response and include three subsets: classical, intermediate, and nonclassical. Little is known about the phenotypical and functional age-related changes in monocytes and their association with soluble inflammatory biomarkers, cytomegalovirus infection, and functional and mental decline. We assayed the activation ex vivo and the responsiveness to TLR2 and TLR4 agonists in vitro in the three subsets and assessed the intracellular production of IL1-alpha (α), IL1-beta (β), IL-6, IL-8, TNF-α, and IL-10 of elderly adults (median 83 [67-90] years old;n= 20) compared with young controls (median 35 [27-40] years old;n= 20). Ex vivo, the elderly adults showed a higher percentage of classical monocytes that expressed intracellular IL1-α (p= .001), IL1-β (p= .001), IL-6 (p= .002), and IL-8 (p= .007). Similar results were obtained both for the intermediate and nonclassical subsets and in vitro. Polyfunctionality was higher in the elderly adults. The functionality ex vivo was strongly associated with soluble inflammatory markers. The activation phenotype was independently associated with the anti-cytomegalovirus IgG levels and with functional and cognitive decline. These data demonstrate that monocytes are key cell candidates for the source of the high soluble inflammatory levels. Our findings suggest that cytomegalovirus infection might be a driving force in the activation of monocytes and is associated with the functional and cognitive decline. PMID:26286603

  20. 99mTc-nanocolloid: Clinical results from its use as a new marker of inflammatory changes

    International Nuclear Information System (INIS)

    Fifty scintigrams were performed on 45 patients using 99mTc-nanocolloid in order to test its affinity for inflammatory lesions; in these patients there was clinical and/or radiological suspicion of an inflammatory process. There was good correlation between the degree of uptake and the activity of the inflammatory process. Specificity is limited because of uptake in certain tumours (e.g. sarcomas of the extremities), but difficulties in differential diagnosis are not expected to be serious. Judging by our experience, 99mTc-nanocolloid is a promising substance for the scintigraphic demonstration of inflammatory foci. The advantages of this industrially prepared tracer over 111In-leucocytes and 67Ga-citrate are discussed. (orig.)

    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.

The incidence of SIRS was lower in patients carrying MBL2 A/O and O/O genotypes (p=0.024). Children with MBL levels 30) (p=0.021). Thus, low MBL concentrations and associated genotypes may protect patients from systemic inflammation while high MBL serum levels and corresponding genotypes are risk factors of postoperative complications.

  6. High intensity interval and endurance training have opposing effects on markers of heart failure and cardiac remodeling in hypertensive rats.

    Directory of Open Access Journals (Sweden)

    Tanya M Holloway

    Full Text Available There has been re-emerging interest and significant work dedicated to investigating the metabolic effects of high intensity interval training (HIIT in recent years. HIIT is considered to be a time efficient alternative to classic endurance training (ET that elicits similar metabolic responses in skeletal muscle. However, there is a lack of information on the impact of HIIT on cardiac muscle in disease. Therefore, we determined the efficacy of ET and HIIT to alter cardiac muscle characteristics involved in the development of diastolic dysfunction, such as ventricular hypertrophy, fibrosis and angiogenesis, in a well-established rodent model of hypertension-induced heart failure before the development of overt heart failure. ET decreased left ventricle fibrosis by ~40% (P < 0.05, and promoted a 20% (P<0.05 increase in the left ventricular capillary/fibre ratio, an increase in endothelial nitric oxide synthase protein (P<0.05, and a decrease in hypoxia inducible factor 1 alpha protein content (P<0.05. In contrast, HIIT did not decrease existing fibrosis, and HIIT animals displayed a 20% increase in left ventricular mass (P<0.05 and a 20% decrease in cross sectional area (P<0.05. HIIT also increased brain natriuretic peptide by 50% (P<0.05, in the absence of concomitant angiogenesis, strongly suggesting pathological cardiac remodeling. The current data support the longstanding belief in the effectiveness of ET in hypertension. However, HIIT promoted a pathological adaptation in the left ventricle in the presence of hypertension, highlighting the need for further research on the widespread effects of HIIT in the presence of disease.

  11. Dietary antioxidant and anti-inflammatory intake modifies the effect of cadmium exposure on markers of systemic inflammation and oxidative stress

    International Nuclear Information System (INIS)

    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

    This study aimed to evaluate the effects of 5 days of 810-nm low-level laser therapy (LLLT) intervention on inflammatory and muscle damage markers and performance in young water polo players. Twenty young male water polo players participated in the study, which was designed as a randomized, double-blinded, placebo-controlled trial. Active LLLT or an identical placebo LLLT were delivered to eight points on the adductor muscle region immediately after each training day. Performance was measured by a 200-m maximal swimming (P200) and a 30-s crossbar jump test (30CJ) which was performed every day before training, and blood samples were drawn pre and post the final LLLT intervention to measure interleukins (IL) and muscle damage markers. There was no significant change in the P200 exercise in the LLLT group compared with the placebo group but there was a moderate improvement in the 30CJ (8.7 ± 2.6 %). IL-1β and tumor necrosis factor-alpha presented increased (P LLLT intervention compared to pre, 0, and 24 h, but did not differ between groups. IL-10 increased over time in the placebo group and reached a moderate effect compared to the LLLT group. The creatine kinase decreased significantly (P = 0.049) over the time within the LLLT treatment group, but there was no significant change in lactate dehydrogenase (P = 0.150). In conclusion, LLLT resulted in a non-significant, but small to moderate effect on inflammatory and muscle damage markers and a moderate effect on performance in water polo players. In addition, the lack of positive results could be due to the small area covered by irradiation and this should be considered in future studies. PMID:26873498

    Although the effects of dietary glycemic index (GI) on insulin resistance are well documented in adults, the complex interaction among glucose intolerance, inflammatory markers, and adipokine concentration has not been well studied, especially among adolescents. We investigated the effect of a low glycemic index (LGI) diet on insulin concentration, fasting blood sugar (FBS), inflammatory markers, and serum adiponectin concentration among healthy obese/overweight adolescent females. In this parallel randomized clinical trial, 2 different diets, an LGI diet and a healthy nutritional recommendation diet (HNRD) with similar macronutrient composition were prescribed to 50 obese and overweight adolescent girls with the same pubertal status. Biochemical markers FBS, serum insulin concentration, high sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), and adiponectin were measured before and after a 10 week intervention. Using an intention-to-treat analysis, data from 50 subjects were analyzed. According to a dietary assessment, GI in the LGI group was 43.22±0.54. While the mean for FBS, serum insulin concentration, the homeostasis model assessment (HOMA), the quantitative insulin sensitivity check index (QUICKI), and adiponectin concentration did not differ significantly within each group, the average hs-CRP and IL-6 decreased significantly in the LGI diet group after the 10 week intervention (p=0.009 and p=0.001; respectively). Comparing percent changes, we found a marginally significant decrease in hs-CRP in the LGI group compared with the HNRD group after adjusting for confounders. Compliance with an LGI diet may have favorable effect on inflammation among overweight and obese adolescent girls. PMID:27065462

    Despite advances in prevention and treatment of heart transplant rejection, development of cardiac allograft vasculopathy (CAV) remains the leading factor limiting long-term survival of the graft. Cardiac allograft vasculopathy etiopathogenesis is not fully understood, but a significant role is attributed to endothelial cell damage, caused by immunological and non-immunological mechanisms. Immunological factors include the differences between the recipient's and the donor's HLA systems, the presence of alloreactive antibodies and episodes of acute rejection. Among the non-immunological factors the most important are the age of the donor, ischemia-reperfusion injury and cytomegalovirus infection. The classical cardiovascular risk factors (diabetes, hypertension, obesity and hyperlipidemia) are also important. This study presents an up-to-date overview of current knowledge on the vasculopathy etiopathogenesis and the role played by endothelium and inflammatory processes in CAV, and it also investigates the factors which may serve as risk markers of cardiac allograft vasculopathy.

    There has been re-emerging interest and significant work dedicated to investigating the metabolic effects of high intensity interval training (HIIT) in recent years. HIIT is considered to be a time efficient alternative to classic endurance training (ET) that elicits similar metabolic responses in skeletal muscle. However, there is a lack of information on the impact of HIIT on cardiac muscle in disease. Therefore, we determined the efficacy of ET and HIIT to alter cardiac muscle characteristics involved in the development of diastolic dysfunction, such as ventricular hypertrophy, fibrosis and angiogenesis, in a well-established rodent model of hypertension-induced heart failure before the development of overt heart failure. ET decreased left ventricle fibrosis by ~40% (P HIIT did not decrease existing fibrosis, and HIIT animals displayed a 20% increase in left ventricular mass (PHIIT also increased brain natriuretic peptide by 50% (PHIIT promoted a pathological adaptation in the left ventricle in the presence of hypertension, highlighting the need for further research on the widespread effects of HIIT in the presence of disease.

    Background Obesity induced low-grade chronic inflammation disrupts proper immune and metabolic function. Vitamin D deficiency increases inflammation, which is associated with cardiometabolic risk. This systematic review examines the association between oral vitamin D (VD) supplementation and circulating inflammatory biomarkers and glycemic outcomes from randomized controlled trials (RCTs) of overweight and/or obese adults. Methods MEDLINE OVID, EMBASE and the Cochrane Central Register of Controlled Trials were searched according to a predefined protocol. Eligible RCTs included adults randomized to receive either oral VD or placebo. Two reviewers independently assessed RCTs for inclusion. Bias was assessed using the Cochrane Collaboration risk of bias tool. Mean differences were calculated comparing end-of-study sample means between the independent VD and placebo groups. Results Eleven unique RCTs met inclusion criteria from a total of 3,383 identified citations, including 79 screened articles and 14 full text data extractions. Inflammatory and glycemic measures were reported in 7 and 10 RCTs, respectively. Most trial findings were non-significant with considerable heterogeneity in design, participants and outcomes. All but one trial was rated as either high or unclear risk of bias. Two RCTs reported significant changes in inflammatory biomarkers; however, the mean difference between groups was not statistically significant: C-reactive protein 0.19 mg/L (p = 0.88); Tumor Necrosis Factor -0.54 pg/ml (p = 0.20). Two other trials found significant mean differences in fasting plasma glucose -0.32 mmol/L (p = 0.03), Hemoglobin A1c -0.13% (p = 0.04), and Homeostatic Model Assessment -0.86 (p = 0.02) following VD supplementation. Conclusions Overall, there is no clear established benefit of VD supplementation on inflammatory biomarkers among overweight/obese adults. Baseline serum VD possibly influences the effect of VD repletion on inflammatory markers. Risk of bias was

    Full Text Available Sudden cardiac death continues to be a major public health problem. Ventricular arrhythmia is a main cause of sudden cardiac death. The present review addresses the links between renal function tests, several laboratory markers, and ventricular arrhythmia risk in patients with renal disease, undergoing or not hemodialysis or renal transplant, focusing on recent clinical studies. Therapy of hypokalemia, hypocalcemia, and hypomagnesemia should be an emergency and performed simultaneously under electrocardiographic monitoring in patients with renal failure. Serum phosphates and iron, PTH level, renal function, hemoglobin and hematocrit, pH, inflammatory markers, proteinuria and microalbuminuria, and osmolarity should be monitored, besides standard 12-lead ECG, in order to prevent ventricular arrhythmia and sudden cardiac death.

    Recently, a potential link between infectious agents and athero-sclerosis has been suggested. H. pylori strains bearing the cytotoxin associated gene A (Cag-A) provoked a heightened inflammatory response in vivo and showed stronger relation to gastric complication of this infection. The association between Cag-A positive strain and vascular diseases producing conflicting results. So, the present study aimed to estimate the seroprevalence of H. pylori Cag-A positive strains as a risk factor among different groups of ischemic heart disease and to study its interaction with high sensitivity CRP (hs-CRP) and IL6 as inflammatory host responses. The present study was conducted on anti H. pylori IgG positive 60 ischemic heart disease (IHD) patients and 20 apparently healthy individuals as a control group. IHD patients were classified into 3 groups: (group I) with acute myocardial infarction, unstable angina pectoris patients (group II), chronic stable angina pectoris patients (group III). For all patients and control groups serum anti Cag-A IgG, IL6, hs-CRP, CK, CKMB, LDH, AST and Lipid profile were estimated. IL6 and hs-CRP levels were increased in groups I, II and III as compared with group IV (P < 0.001) with positive correlation between IL6 and hs-CRP in groups I, II and III (P < 0.05). The percentage of anti Cag-A positive cases was similar among the patient groups, but significantly higher than in the control group. Thus, infection with Cag-A positive H. pylori strain may play a role as a risk factor in development of ischemic heart diseases through provocation of high inflammatory response or through other mechanism. Therefore eradication of this infection is important as it is much less expensive than long term treatment of the other risk factors. PMID:20726321

    Full Text Available OBJECTIVES: In patients with suspected acute coronary syndrome (ACS, rapid triage is essential. The aim of this study was to establish a tool for risk prediction of 30-day cardiac events (CE on admission. 30-day cardiac events (CE were defined as early coronary revascularization, subsequent myocardial infarction, or cardiovascular death within 30 days. METHODS AND RESULTS: This single-centre, prospective cohort study included 377 consecutive patients presenting to the emergency department with suspected ACS and for whom troponin T measurements were requested on clinical grounds. Fifteen biomarkers were analyzed in the admission sample, and clinical parameters were assessed by the TIMI risk score for unstable angina/Non-ST myocardial infarction and the GRACE risk score. Sixty-nine (18% patients presented with and 308 (82% without ST-elevations, respectively. Coronary angiography was performed in 165 (44% patients with subsequent percutaneous coronary intervention--accounting for the majority of CE--in 123 (33% patients, respectively. Eleven out of 15 biomarkers were elevated in patients with CE compared to those without. High-sensitive troponin T (hs-cTnT was the best univariate biomarker to predict CE in Non-ST-elevation patients (AUC 0.80, but did not yield incremental information above clinical TIMI risk score (AUC 0.80 vs 0.82, p = 0.69. Equivalence testing of AUCs of risk models and non-inferiority testing demonstrated that the clinical TIMI risk score alone was non-inferior to its combination with hs-cTnT in predicting CE. CONCLUSIONS: In patients presenting without ST-elevations, identification of those prone to CE is best based on clinical assessment based on TIMI risk score criteria and hs-cTnT.

    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. PMID:26890580

    Functional food-flaxseed and its derivatives (flaxseed oil or lignans) are beneficial for human health, possibly because of their anti-inflammatory effects. C-reactive protein (CRP), a sensitive marker of inflammation was chosen to evaluate the anti-inflammatory effects of flaxseed. We searched randomized controlled trials from PubMed and the Cochrane Library in October 2015 and conducted a meta-analysis to evaluate the effectiveness of flaxseed and its derivatives on CRP. The mean differences (net change) in CRP (mg/L) concentrations were pooled with a random- or a fixed-effects model depending on the results of heterogeneity tests. Overall, flaxseed interventions had no effects on reduction of CRP (p = 0.428). The null effects were consistent in the subgroup analysis with multiple studies and population characteristics. Significant heterogeneity was observed in most of the analyses. Meta-regression identified baseline body mass index (BMI) as a significant source of heterogeneity (P-interaction = 0.032), with a significant reduction in CRP of 0.83 mg/L (95% confidence interval -1.34 to -0.31; p = 0.002) among subjects with a BMI of ≥30 kg/m². In conclusion, our meta-analysis did not find sufficient evidence that flaxseed and its derivatives have a beneficial effect on reducing circulating CRP. However, they may significantly reduce CRP in obese populations. PMID:26959052

    Background Genital granulomas induced by Schistosoma haematobium eggs can manifest as different lesion types visible by colposcopy; rubbery papules (RP), homogenous sandy patches (HSP) and grainy sandy patches (GSP). Pronounced tissue eosinophilia is a candidate marker for active S. haematobium pathology, as viable schistosome egg granulomas often are eosinophil rich. Here it was investigated whether eosinophil granule proteins ECP (eosinophil cationic protein) and EPX (eosinophil protein-X) in urine and genital lavage can be used as markers for active FGS lesions. Methods Uro-genital samples from 118 Malagasy women were analysed for ECP and EPX by standard sandwich avidin/biotin amplified ELISA. Principal findings The women with RP lesions had significantly higher levels of ECP and EPX in both lavage and urine. Furthermore, women with RP lesions were significantly younger than those with GSP. This could indicate that RP lesions might be more recently established and thus represent an earlier inflammatory lesion stage. Conclusion ECP in genital lavage might be a future tool aiding the identification of FGS pathology at a stage where reversibility remains a possibility following praziquantel treatment.

    Full Text Available Genital granulomas induced by Schistosoma haematobium eggs can manifest as different lesion types visible by colposcopy; rubbery papules (RP, homogenous sandy patches (HSP and grainy sandy patches (GSP. Pronounced tissue eosinophilia is a candidate marker for active S. haematobium pathology, as viable schistosome egg granulomas often are eosinophil rich. Here it was investigated whether eosinophil granule proteins ECP (eosinophil cationic protein and EPX (eosinophil protein-X in urine and genital lavage can be used as markers for active FGS lesions.Uro-genital samples from 118 Malagasy women were analysed for ECP and EPX by standard sandwich avidin/biotin amplified ELISA.The women with RP lesions had significantly higher levels of ECP and EPX in both lavage and urine. Furthermore, women with RP lesions were significantly younger than those with GSP. This could indicate that RP lesions might be more recently established and thus represent an earlier inflammatory lesion stage.ECP in genital lavage might be a future tool aiding the identification of FGS pathology at a stage where reversibility remains a possibility following praziquantel treatment.

    The exact mechanism by which hypothermic machine perfusion (HMP) improves the graft quality in kidney transplantation of donation after cardiac death (DCD) remains unclear. The aim of this study was to investigate the correlation between the expression of matrix metalloproteinase 9 (MMP-9) and inflammatory reaction in kidney ischemia-reperfusion (I/R) injury injury followed by cold storage (CS) or HMP model of DCD. New Zealand white rabbit kidneys were subjected to 35 min of warm ischemia and 1 h reperfusion, then preserved by either 1 h reperfusion (sham-operated group), 4 h CS or 4 h HMP in vivo. Kidneys were reperfused 24 h followed by further analysis. No treatment was given to rabbits in the normal control group. The expression of MMP-9, nuclear factor-κB (NF-κB), and MMP-2 mRNA were detected by real-time PCR (RT-PCR). MMP-9 was located by immunohistochemistry and immunofluorescence methods. Tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), myeloperoxidase (MPO), superoxide dismutase (SOD), and malondialdehyde (MDA) were measured by kits for each groups. Compared with the CS group, the expression of MMP-9 and NF-κB mRNA were downregulated in HMP group (P  0.05). In normal control and sham-operated groups, a low level of MMP-9 expression was detected in glomeruli. However, positive signals of MMP-9 were mostly located in the tubulointerstitium and the vascular wall of CS and HMP groups. Expression of TNF-α, IL-6, MDA, and activity of MPO decreased while activity of SOD in the HMP group increased in contrast to the CS group (P < 0.05). In conclusion, inflammatory cytokines mediated MMP-9 expression through NF-κB band to MMP-9 promoter region, resulting in renal injury. Therefore, HMP reduced inflammatory reaction by downregulating the expression of MMP-9, which may be the mechanism of kidney protection in I/R injury. PMID:26813475

    A better understanding of the inflammatory process associated with renal ischaemia-reperfusion (IR) injury may be clinically important. In this study we examined the role of the kidney in production of inflammatory mediators by analysing renal lymph after 30 min unilateral occlusion of renal artery followed by 120 min reperfusion, as well as the effect of IR on size selectivity for proteins in both glomerular and peritubular capillaries. All measured mediators increased dramatically in renal hilar lymph, plasma and renal cortical tissue samples and returned to control levels after 120 min reperfusion. The responses were differentiated; interleukin-1β, monocyte chemoattractant protein-1 and leptin were markedly increased in plasma before reperfusion, reflecting an extrarenal response possibly induced by afferent renal nerve activity from the ischaemic kidney. Tumour necrosis factor-α was the only mediator showing elevated lymph-to-plasma ratio following 30 min reperfusion, indicating that most cytokines were released directly into the bloodstream. The IR-induced rise in cytokine levels was paralleled by a significant increase in high molecular weight plasma proteins in both lymph and urine. The latter was shown as a 14- to 166-fold increase in glomerular sieving coefficient of plasma proteins assessed by a novel proteomic approach, and indicated a temporarily reduced size selectivity of both glomerular and peritubular capillaries. Collectively, our data suggest that cytokines from the ischaemic kidney explain most of the rise in plasma concentration, and that the locally produced substances enter the systemic circulation through transport directly to plasma and not via the interstitium to lymph.

    Several lines of evidence suggest aberrant immune response in schizophrenia, including elevated levels of cytokines. These cytokines are thought to be produced by activated microglia, the innate immune cells of the central nervous system. However, increase in translocator protein 18 kDa (TSPO), a marker of activated glia, has not been found in patients with chronic schizophrenia using second-generation radiotracers and positron emission tomography (PET)-based neuroimaging. In this study we focused on patients with recent onset of schizophrenia (within 5 years of diagnosis). Quantified levels of TSPO in the cortical and subcortical brain regions using the PET-based radiotracer [(11)C]DPA-713 were compared between the patients and healthy controls. Markers of inflammation, including interleukin 6 (IL-6), were assessed in the plasma and cerebrospinal fluid (CSF) in these participants. We observed no significant change in the binding of [(11)C]DPA-713 to TSPO in 12 patients with recent onset of schizophrenia compared with 14 controls. Nevertheless, the patients with recent onset of schizophrenia showed a significant increase in IL-6 in both plasma (Pschizophrenia alone (P=0.03). Our results suggest that increased levels of IL-6 may occur in the absence of changed TSPO PET signal in the brains of medicated patients with recent onset of schizophrenia. Future development of PET-based radiotracers targeting alternative markers of glial activation and immune response may be needed to capture the inflammatory signature present in the brains of patients with early-stage disease.

    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

    Full Text Available Expansion of intra-abdominal adipose tissue and the accompanying inflammatory response has been put forward as a unifying link between obesity and the development of chronic diseases. However, an apparent sexual dimorphism exists between obesity and chronic disease risk due to differences in the distribution and abundance of adipose tissue. A range of experimental protocols have been employed to demonstrate the role of estrogen in regulating health benefits; however, most studies are confounded by significant differences in body weight and adiposity. Therefore, the purpose of this study was to compare weight-matched obese male and female mice to determine if the sex-dependent health benefits remain when body weight is similar. The development of obesity in female mice receiving a high-fat diet was delayed; however, subsequent comparisons of weight-matched obese mice revealed greater adiposity in obese female mice. Despite excess adiposity and enlarged adipocyte size, obese females remained more glucose tolerant than weight-matched male mice, and this benefit was associated with increased expression of adiponectin and reductions in immune cell infiltration and oxidative stress in adipose tissue. Therefore, the protective benefits of estrogen persist in the obese state and appear to improve the metabolic phenotype of adipose tissue and the individual.

    Full Text Available Background and Objective: High-intensity interval training (HIIT is a recently proposed exercise protocol, which is time-effective. The aim of this study was to evaluate the effect of HIIT for 8 weeks on the lipid profile, C-reactive protein (CRP, fasting blood sugar (FBS and anthropometric parameters of young women who do not exercise. Methods: In this study, 20 young physically inactive women performed HIIT workouts for 8 weeks and 3 sessions per week. The training protocol consisted of 10-times treadmill running for 15 seconds at maximum effort and then 30 seconds of resting. Blood samples were taken while fasting, a day before and after the training and then the considered parameters were measured. Wilcoxon test was used to compare the obtained data. Results: HIIT significantly reduced FBS, cholesterol, low-density lipoprotein, high-density lipoprotein /cholesterol ratio and CRP while increasing the HDL levels. There was a significant difference in the weight, body fat percentage, waist circumference, abdominal circumference and chest circumference of the subjects before and after the training (p <0.05. Conclusion: HIIT can improve lipid, inflammatory and anthropometric parameters, thus it can be considered as a suitable alternative to time-consuming exercises, especially for physically inactive women who like to spend less time to achieve optimal physical wellness and body fitness.

    Full Text Available Pulse oximetry, which noninvasively detects the blood flow of peripheral tissue, has achieved widespread clinical use. We have noticed that the better the quality of cardiopulmonary resuscitation (CPR, the better the appearance of pulse oximetry plethysmographic waveform (POP. We investigated whether the area under the curve (AUC and/or the amplitude (Amp of POP could be used to monitor the quality of CPR.Prospective, randomized controlled study.Animal experimental center in Peking Union Medical Collage Hospital, Beijing, China.Healthy 3-month-old male domestic swine.34 local pigs were enrolled in this study. After 4 minutes of untreated ventricular fibrillation, animals were randomly assigned into two resuscitation groups: a "low quality" group (with a compression depth of 3cm and a "high quality" group (with a depth of 5cm. All treatments between the two groups were identical except for the depth of chest compressions. Hemodynamic parameters [coronary perfusion pressure (CPP, partial pressure of end-tidal carbon dioxide (PETCO2] as well as AUC and Amp of POP were all collected and analyzed.There were statistical differences between the "high quality" group and the "low quality" group in AUC, Amp, CPP and PETCO2 during CPR (P<0.05. AUC, Amp and CPP were positively correlated with PETCO2, respectively (P<0.01. There was no statistical difference between the heart rate calculated according to the POP (FCPR and the frequency of mechanical CPR at the 3rd minute of CPR. The FCPR was lower than the frequency of mechanical CPR at the 6th and the 9th minute of CPR.Both the AUC and Amp of POP correlated well with CPP and PETCO2 in animal models. The frequency of POP closely matched the CPR heart rate. AUC and Amp of POP might be potential noninvasive quality monitoring markers for CPR.

    Postoperative cognitive dysfunction (POCD) is a debilitating surgical complication, with cardiac surgery patients at particular risk. To gain insight in the mechanisms underlying the higher incidence of POCD after cardiac versus non-cardiac surgery, systemic and central inflammatory changes, alterations in intraneuronal pathways, and cognitive performance were studied after cardiac and abdominal surgery in rats. Male Wistar rats were subjected to ischemia reperfusion of the upper mesenteric artery (abdominal surgery) or the left coronary artery (cardiac surgery). Control rats remained naïve, received anesthesia only, or received thoracic sham surgery. Rats were subjected to affective and cognitive behavioral tests in postoperative week 2. Plasma concentrations of inflammatory factors, and markers for neuroinflammation (NGAL and microglial activity) and the BDNF pathway (BDNF, p38MAPK and DCX) were determined. Spatial memory was impaired after both abdominal and cardiac surgery, but only cardiac surgery impaired spatial learning and object recognition. While all surgical procedures elicited a pronounced acute systemic inflammatory response, NGAL and TNFα levels were particularly increased after abdominal surgery. Conversely, NGAL in plasma and the paraventricular nucleus of the hypothalamus and microglial activity in hippocampus and prefrontal cortex on postoperative day 14 were increased after cardiac, but not abdominal surgery. Both surgery types induced hippocampal alterations in BDNF signaling. These results suggest that POCD after cardiac surgery, compared to non-cardiac surgery, affects different cognitive domains and hence may be more extended rather than more severe. Moreover, while abdominal surgery effects seem limited to hippocampal brain regions, cardiac surgery seems associated with more wide spread alterations in the brain. PMID:26867718

    Background Aspirin can inhibit inflammatory reactions and platelet aggregation, but little is known about the effects of the combination of aspirin plus clopidogrel, a new antiplatelet agent, on inflammation. The purpose of this study was to determine whether aspirin plus clopidogrel can further suppress inflammation in patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). Methods One hundred and fifteen patients with NSTEACS were randomized into two groups: group A (aspirin alone, n=58) and group B (aspirin plus clopidogrel, n=57). Patients in group A received a loading dose of 300 mg aspirin, then 100 mg per day. The patients in group B received a loading dose of 300 mg aspirin and 300 mg clopidogrel, then 100 mg aspirin and 75 mg clopidogrel per day. Serum high sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α(TNF-α) were measured in all patients at baseline prior to any drug treatment after admission, and at 7 and 30 days after beginning drug treatment. Thirty healthy volunteers on no medications were enrolled as controls (group C).Results Baseline levels of hs-CRP and TNF-αin group A and group B were significantly higher than those in group C. Seven days after administration, the levels of hs-CRP in both group A and group B decreased significantly [Group A: (6.15 ± 1.39) mg/L vs (9.18 ± 1.62) mg/L, P <0.01; Group B:(4.99 ± 1.62) mg/L vs (10.29 ± 1.47) mg/L, P<0.01]. Similarly, levels of TNF-αin both groups decreased at 7 days compared to baseline [Group A: (90.99 ± 28.91) pg/ml vs (117.20 ± 37.13) pg/ml, P <0.01; Group B: (74.32± 21.83) pg/ml vs (115.27 ± 32.11) pg/ml, P <0.01]. Thirty days after administration, the levels of hs-CRP in both group A and group B decreased further to (3.49 ± 1.53) mg/L, and (2.40 ± 1.17) mg/L respectively (P <0.01 for both comparisons). Levels of TNF-αin groups A and B also decreased significantly between 7 and 30 days, to 63.28 ± 29.01 pg/ml (group A) and (43.95 ± 17.10) pg

    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

    Cardiac cachexia is a serious complication of chronic heart failure, characterized by significant weight loss and body wasting. Chronic heart failure-related muscle wasting results from a chronic imbalance in the activation of anabolic or catabolic pathways, caused by a series of immunological, metabolic, and neurohormonal processes. In spite of the high morbidity and mortality associated to this condition, there is no universally accepted definition or specific biomarkers for cardiac cachexia, which makes its diagnosis and treatment difficult. Several hormonal, inflammatory and oxidative stress molecules have been proposed as serological markers of prognosis in cardiac cachexia but with doubtful success. As individual biomarkers may have limited sensitivity and specificity, multimarker strategies involving mediators of the biological processes modulated by cardiac cachexia will strongly contribute for the diagnosis and management of the disease, as well as for the establishment of new therapeutic targets. An integrated analysis of the biomarkers proposed so far for cardiac cachexia is made in the present review, highlighting the biological processes to which they are related. PMID:24978823

    Full Text Available OBJECTIVES: We explored whether high blood pressure is associated with metabolic, inflammatory and prothrombotic dysregulation in patients with metabolic syndrome. METHODS: 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. RESULTS: 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. CONCLUSIONS: High blood pressure, which may be related to the autonomic dysfunction, is associated with metabolic, inflammatory and prothrombotic dysregulation in patients with

    Full Text Available The host immune response plays an important role in viral clearance in patients who are chronically infected with hepatitis C virus (HCV and are treated with interferon and ribavirin. Activation of the immune system involves the release of pro and anti-inflammatory molecules that can be measured in plasma samples. The present study aimed to evaluate the association between pretreatment plasma levels of chemokines and soluble tumor necrosis factor receptors (sTNF-R and the virological response in treated patients with chronic hepatitis C infection. Forty-one chronically-infected HCV patients that were being treated with interferon-α (IFN-α plus ribavirin were included in the study. Socio-demographic, clinical and laboratory data were collected and pretreatment plasma levels of chemokine CCL2, CCL3, CCL11, CCL24, chemokine CXCL9, CXCL10, sTNF-R1 and sTNF-R2 were measured. The virological response was assessed at treatment week 12, at the end of treatment and 24 weeks after treatment. Pretreatment CXCL10 levels were significantly higher in patients without an early virological response (EVR or sustained virological response (SVR compared to responders [512.9 pg/mL vs. 179.1 pg/mL (p = 0.011 and 289.9 pg/mL vs. 142.7 pg/mL (p = 0.045, respectively]. The accuracy of CXCL10 as a predictor of the absence of EVR and SVR was 0.79 [confidence interval (CI 95%: 0.59-0.99] and 0.69 (CI 95%: 0.51-0.87, respectively. Pretreatment plasma levels of the other soluble inflammatory markers evaluated were not associated with a treatment response. Pretreatment CXCL10 levels were predictive of both EVR and SVR to IFN-α and ribavirin and may be useful in the evaluation of candidates for therapy.

    The presence of inflammatory reaction in peri-tumoural connective tissue is generally considered as a defense mechanism against cancer, but inflammation tissue in malignant transformation and early steps of oncogenesis has been recently proven to play a supporting and aggravating role in some carcinomas. Aims of this retrospective study were to evaluate in OSCCs the independent association of peri-tumoral inflammatory infiltrate (PTI) with local recurrence (LR) or survival outcome, and to verify whether PTI can be considered a marker of prognosis. Data from 211 cases of OSCC, only surgically treated between 1990 and 2000, were collected and retrospectively analyzed for PTI and the event LR (5 yrs follow-up at least) by means of univariate-multivariate and neural networks analyses. Patients (mean age 65.3 ± 12.4 yrs, M/F = 2.98) showed presence of PTI in 68.2% (144/211): (+) in 27.0%, (++) in 25.6%, (+++) 15.6%; PTI was found reduced in 24.7% of cases and absent in 7.1%. In overall PTI+ve group (n=144), 66 were TNM Stage I, 33 Stage II, 45 Stage III, none Stage IV. LR (mean 6 ± 4 months) was present in 87/211 (41.2%) patients, of which 43/144 (29.8%) in OSCCs with PTI [23 (+), 13 (++) and 7 (+++)] vs. 44/67 (65.7%) in OSCC with PTI -/+ or PTI-ve ones. By univariate analysis, PTI+ve cases showed a significant lower risk to have LR (p neural networks) confirmed the same datum: presence of PTI was an independent predictive variable accounting for a better tumoural outcome without LR (Logit and neural networks values: OR' 0.226; CI= 0.113:0.454; ROC Area = 0.66, respectively). In terms of prognostic significance, elevated PTI was found to have an independent association with the poorest overall survival rate (P = 0.056). Our findings strongly suggest the importance to investigate routinely PTI in OSCCs, as useful marker of tumoral behavior and prognosis, and warrant further studies. PMID:21781456

    Full Text Available Low-level laser therapy (LLLT has been used as an anti-inflammatory treatment in several disease conditions, even when inflammation is a secondary consequence, such as in myocardial infarction (MI. However, the mechanism by which LLLT is able to protect the remaining myocardium remains unclear. The present study tested the hypothesis that LLLT reduces inflammation after acute MI in female rats and ameliorates cardiac function. The potential participation of the Renin-Angiotensin System (RAS and Kallikrein-Kinin System (KKS vasoactive peptides was also evaluated. LLLT treatment effectively reduced MI size, attenuated the systolic dysfunction after MI, and decreased the myocardial mRNA expression of interleukin-1 beta and interleukin-6 in comparison to the non-irradiated rat tissue. In addition, LLLT treatment increased protein and mRNA levels of the Mas receptor, the mRNA expression of kinin B2 receptors and the circulating levels of plasma kallikrein compared to non-treated post-MI rats. On the other hand, the kinin B1 receptor mRNA expression decreased after LLLT. No significant changes were found in the expression of vascular endothelial growth factor (VEGF in the myocardial remote area between laser-irradiated and non-irradiated post-MI rats. Capillaries density also remained similar between these two experimental groups. The mRNA expression of the inducible nitric oxide synthase (iNOS was increased three days after MI, however, this effect was blunted by LLLT. Moreover, endothelial NOS mRNA content increased after LLLT. Plasma nitric oxide metabolites (NOx concentration was increased three days after MI in non-treated rats and increased even further by LLLT treatment. Our data suggest that LLLT diminishes the acute inflammation in the myocardium, reduces infarct size and attenuates left ventricle dysfunction post-MI and increases vasoactive peptides expression and nitric oxide (NO generation.

No significant changes were found in the expression of vascular endothelial growth factor (VEGF) in the myocardial remote area between laser-irradiated and non-irradiated post-MI rats. Capillaries density also remained similar between these two experimental groups. The mRNA expression of the inducible nitric oxide synthase (iNOS) was increased three days after MI, however, this effect was blunted by LLLT. Moreover, endothelial NOS mRNA content increased after LLLT. Plasma nitric oxide metabolites (NOx) concentration was increased three days after MI in non-treated rats and increased even further by LLLT treatment. Our data suggest that LLLT diminishes the acute inflammation in the myocardium, reduces infarct size and attenuates left ventricle dysfunction post-MI and increases vasoactive peptides expression and nitric oxide (NO) generation.

    Full Text Available Several immunopathogenic mechanisms have been proposed to explain the massive increase of vascular permeability observed in the severe forms of infection by Dengue Virus (DENV. Our aim was to determine the kinetic changes of inflammatory mediators (IL-8, TNF- α, soluble early lymphocyte activation markers (sIL-2R, sTNF-Rp75 and soluble fractions of cell adhesion molecules (sICAM-1 and sVCAM-1 as indicators for early recognition of disease severity in patients with laboratory-confirmed dengue. Twenty patients classified as Dengue±Warning Signs (D±WS and thirty patients with Severe Dengue (SD were included in the study. Serums of apparently healthy individuals were included as controls. Compared with normal subjects, D±WS cases did not show significant differences in the levels of IL-8 or TNF-α during the acute nor in the critical stages of the disease; however, in D±WS cases levels of sICAM-1 and sVCAM-1 were higher than controls during both phases; in contrast, significant increase of sTNF-p75 and sIL2R levels were observed during the critical phase of the disease. Compared with both dengue patients and controls, patients with SD showed significant rise in the levels of IL-8 and TNF-α during the critical phase of the disease and a significant increase in adhesion molecules were detected in both phases, but the highest levels of sVCAM-1 and sIL-2R were observed only during the acute stage of the disease. In conclusion, sIL-2R and sVCAM-1, as early markers of lymphocyte and endothelial activation, would serves as indicators of severity during the acute phase of dengue infection.

    Context The antioxidative properties of plants or plant derivative products are well known for their free radical scavenging effects. Flagellaria indica L. (Flagellariaceae) (FI) is a tropical medicinal plant used by the natives of Sabah as medication for semi-paralysis. Objective This study evaluates the hepatoprotective mechanism of FI against carbon tetrachloride (CCl4)-mediated liver damage. Materials and methods Aqueous extract of FI leaves was orally administered to adult Sprague-Dawley rats once daily for 14 consecutive days at 300, 400, and 500 mg/kg b.w. prior to CCl4 treatment (1.0 mL/kg b.w.) on the 13th and 14th days. Results Total phenolic content in the aqueous extract of FI leaves was 65.88 ± 1.84 mg gallic acid equivalent/g. IC50 value for free radical scavenging activity of FI aqueous extract was reached at the concentration of 400 μg/mL. Biochemical studies show that the aqueous extract of FI was able to prevent the increase in levels of serum transaminases, alanine aminotransferase, and aspartate aminotransferase (38-74% recovery), and malondialdehyde formation (25-87% recovery) in a dose-dependent manner. Immunohistochemical results evidenced the suppression of oxidative stress markers (4-hydroxynonenal and 8-hydroxydeoxyguanosine) and pro-inflammatory markers (tumour necrosis factor-α, interleukin-6, prostaglandin E2). Histopathological and hepatocyte ultrastructural alterations proved that there were protective effects in FI against CCl4-mediated liver injury. Signs of toxicity were not present in rats treated with FI alone (500 mg/kg b.w.). Discussion and conclusion It can be concluded that the presence of phenolic constituents and their antioxidative effects can be credited to the hepatoprotective activity of FI. PMID:26810847

    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.

    Hepatocellular carcinoma is one of the most common lethal diseases worldwide and there is no effective treatment till date. Natural products derived from the plants play an important role in chemoprevention and act as therapeutic antitumor agents. Licorice is a plant that has been used in food and medicine for the treatment of various diseases. 18β-Glycyrrhetinic acid (18β-GA), a pentacyclic triterpenoid obtained from the roots of licorice plant, is reported to possess various pharmacological properties such as antitumor and antiinflammatory activities. The present study was designed to elucidate the chemopreventive effect of 18β-GA through antiinflammation, antiproliferation, and induction of apoptosis in human hepatoma cell line HepG2. 18β-GA significantly inhibits the proliferation of HepG2 cell without affecting the normal liver cell line (Chang's). In the present study, 18β-GA increased the formation of reactive oxygen species, nitric oxide production, and loss of mitochondrial membrane potential, suggesting the involvement of 18β-GA in apoptosis which was also confirmed by assessing the markers involved in apoptosis like caspase-3, caspase-9, Bax:Bcl-2 ratio, and cleaved PARP. 18β-GA also downregulated the expression of inflammatory proteins such as NF-κB, iNOS, and COX-2. Keeping these data into consideration, our results suggest that 18β-GA may be used as a chemopreventive agent in liver cancer. PMID:27116616

    Full Text Available The aim of this study was to investigate the effect of 12 weeks of aerobic training on the serum levels of adiponectin and leptin and on inflammatory markers of coronary heart disease in obese men. Sixteen non-athlete obese men were randomly assigned to one of two experimental groups. The experimental group underwent aerobic training consisting of three sessions per week for 12 weeks, while the control group did not participate in the training programme during the study period. Five millilitres of venous blood was taken from each participant at the beginning of the study, during week six and at the end of week 12 to measure the levels of leptin, adiponectin, C-reactive protein, interleukin-6 and tumour necrosis factor-α. The findings showed that aerobic training led to decreases in the levels of CRP (P=0.002, IL-6 (P = 0.001 and leptin (P = 0.003 and an increase in the level of adiponectin (P = 0.002 in the experimental group relative to the control group. In addition, the level of TNF-α decreased in the experimental group after the 12-week aerobic training period, although this change was not statistically significant. According to the results of this study, regular aerobic exercise decreases the potential risk of coronary heart disease by improving the plasma levels of IL-6, adiponectin, leptin and CRP. Additionally, aerobic exercise can be used as effective non-pharmacological treatment to prevent diseases.

    Full Text Available Cardiac sympathetic neurodegeneration and dysautonomia affect patients with sporadic and familial Parkinson's disease (PD and are currently proposed as prodromal signs of PD. We have recently developed a nonhuman primate model of cardiac dysautonomia by iv 6-hydroxydopamine (6-OHDA. Our in vivo findings included decreased cardiac uptake of a sympathetic radioligand and circulating catecholamines; here we report the postmortem characterization of the model. Ten adult rhesus monkeys (5-17 yrs old were used in this study. Five animals received 6-OHDA (50 mg/kg i.v. and five were age-matched controls. Three months post-neurotoxin the animals were euthanized; hearts and adrenal glands were processed for immunohistochemistry. Quantification of immunoreactivity (ir of stainings was performed by an investigator blind to the treatment group using NIH ImageJ software (for cardiac bundles and adrenals, area above threshold and optical density and MBF StereoInvestigator (for cardiac fibers, area fraction fractionator probe. Sympathetic cardiac nerve bundle analysis and fiber area density showed a significant reduction in global cardiac tyrosine hydroxylase-ir (TH; catecholaminergic marker in 6-OHDA animals compared to controls. Quantification of protein gene protein 9.5 (pan-neuronal marker positive cardiac fibers showed a significant deficit in 6-OHDA monkeys compared to controls and correlated with TH-ir fiber area. Semi-quantitative evaluation of human leukocyte antigen-ir (inflammatory marker and nitrotyrosine-ir (oxidative stress marker did not show significant changes 3 months post-neurotoxin. Cardiac nerve bundle α-synuclein-ir (presynaptic protein was reduced (trend in 6-OHDA treated monkeys; insoluble proteinase-K resistant α-synuclein (typical of PD pathology was not observed. In the adrenal medulla, 6-OHDA monkeys had significantly reduced TH-ir and aminoacid decarboxylase-ir. Our results confirm that systemic 6-OHDA dosing to nonhuman primates

    Full Text Available Background: Impairment of intestinal barrier function and increased translocation of bacteria to the systemic blood flow contribute to the emergence of sepsis. Probiotics might be of beneficial effects on critically ill-patients, modulating intestinal barrier function and reducing inflammation. The aim of this trial was to determine the effect of probiotics on inflammatory markers in critically ill-patients in Intensive Care Unit (ICU. Materials and Methods: This trial was conducted on 40 critically ill-patients admitted to the ICU. Patients were randomly assigned to receive placebo or probiotic containing Lactobacillus, Bifidobacterium and Streptococcus thermophilus (VSL#3 for 7 days. Acute Physiology and Chronic Health Evaluation (APACHE II score Sequential Organ Failure Assessment (SOFA and systemic concentrations of interleukin-6 (IL-6, procalcitonin (PCT and protein C were measured before initiation of the study and on days 4 and 7. Results: A significant difference in IL-6 (P = 0.003, PCT (P = 0.014 and protein C (P < 0.001 levels, and also APACHE II and SOFA scores (P < 0.001 was seen over the treatment period between two groups. Moreover, there was a significant decrease in serum IL-6 levels (from 211.85 ± 112.76 to 71.80 ± 28.41 (P < 0.001 and PCT levels (from 1.67 ± 1.27 to 0.47 ± 0.41 (P < 0.001 and a significant increase in serum protein C levels (from 7.47 ± 3.61 to 12.87 ± 3.63 (P < 0.001 in probiotic group during the study. Conclusion: Probiotics could reduce inflammation in critically ill-patients and might be considered as an adjunctive therapy in the treatment of critically ill-patients.

    The effects of insoluble dietary fibre differing in lignin content on intestinal morphology and mRNA expression was tested in an animal model of 48 weaned piglets. Engaged fibre sources were wheat bran (rich in cellulose and hemicellulose) and pollen from Chinese Masson pine (Pinus massoniana) (rich in lignin), respectively. The fibre sources were added to a basal diet as follows: no addition (control), 3.0% wheat bran, 1.27% pine pollen, and 2.55% pine pollen. The 12 animals of each feeding group were fed four experimental diets ad libitum for 37 days and were then slaughtered for retrieving tissue samples from stomach, jejunum, ileum, colon and mesenterial lymph nodes. Both fibre sources increased villus height of mucosa in jejunum (+10% on average) and ileum (+16% on average). Results of mRNA expression rates of inflammatory, cell cycle and growth marker genes (NFkappaB, TNFalpha, TGFbeta, Caspase3, CDK4, IGF1) were specific to fibre source and tissue: wheat bran induced an up-regulation of NFkappaB in stomach and jejunum, as well as TNFalpha and TGFbeta, and Caspase3 in jejunum. Pine pollen induced down regulation of NFkappaB, TNFalpha, TGFbeta, Caspase3, CDK4 and IGF1 in the colon as well as up-regulation of NFkappaB and TGFbeta in mesenterial lymph nodes. Finally, an overall data comparison based on a hierarchical cluster analysis showed a close relation between gene regulation in different gut sections and organs, as well as between small intestine morphology and zootechnical performance.

Ninety patients with UAP after PCI were randomly and equally assigned to three groups: the XFZY group, the SM group, and the placebo group, with 30 patients in each group. Six syndrome factors (including Qi deficiency, yin deficiency, yang deficiency, blood stasis, phlegm, and Qi stagnation and 4 inflammatory markers (high-sensitivity C-reactive protein (Hs-CRP, endothelins-1 (ET-1, matrix metalloproteinases-9 (MMP-9, and homocysteine (Hcy were observed at week 0 and at the 1st, 4th and 12th weeks. In conclusion, the evolution of syndromes present in patients with UAP after PCI followed these trends (1 The deficiency syndromes gradually increased during a 12-week period, but the excess syndromes first gradually decreased and then mildly increased after PCI. (2 XFZY and SM can prevent excess syndromes from increasing in the later stages and prevent deficiency syndromes from increasing in all stages. (3 XFZY and SMcan reduce the levels of the inflammatory markers, especially in the later stages after PCI.

    Major surgery induces a long fasting time and provokes an inflammatory response which increases the risk of infections. Nutrition given before and during surgery can avoid fasting and has been shown to increase the arginine/asymmetric dimetlhylarginine ratio, a marker of nitric oxide availability, in cardiac tissue and increased concentrations of branched chain amino acids in blood plasma. However, the effect of this new nutritional strategy on organ inflammatory response is unknown. Therefore, we studied the effect of nutrition before and during cardiac surgery on myocardial inflammatory response. In this trial, 32 patients were randomised between enteral, parenteral, and no nutrition supplementation (control) from 2 days before, during, up to 2 days after coronary artery bypass grafting. Both solutions included proteins or amino acids, glucose, vitamins, and minerals. Myocardial atrial tissue was sampled before and after revascularization and was analysed immunohistochemically, subdivided into cardiomyocytic, fatty, and fibrotic areas. Inflammatory cells, especially leukocytes, were present in cardiac tissue in all study groups. No significant differences were found in the myocardial inflammatory response between the enteral, parenteral, and control groups. In conclusion, nutrition given before and during surgery neither stimulates nor diminishes the myocardial inflammatory response in patients undergoing coronary artery bypass grafting. The trial was registered in Netherlands Trial Register (NTR): NTR2183. PMID:26294967

    The toxicity mechanism of nanoparticles on vertebrate cardiovascular system is still unclear, especially on the low-level exposure. This study was to explore the toxic effect and mechanisms of low-dose exposure of silica nanoparticles (SiNPs) on cardiac function in zebrafish embryos via the intravenous microinjection. The dosage of SiNPs was based on the no observed adverse effect level (NOAEL) of malformation assessment in zebrafish embryos. The mainly cardiac toxicity phenotypes induced by SiNPs were pericardial edema and bradycardia but had no effect on atrioventricular block. Using o-Dianisidine for erythrocyte staining, the cardiac output of zebrafish embryos was decreased in a dose-dependent manner. Microarray analysis and bioinformatics analysis were performed to screen the differential expression genes and possible pathway involved in cardiac function. SiNPs induced whole-embryo oxidative stress and neutrophil-mediated cardiac inflammation in Tg(mpo:GFP) zebrafish. Inflammatory cells were observed in atrium of SiNPs-treated zebrafish heart by histopathological examination. In addition, the expression of TNNT2 protein, a cardiac contraction marker in heart tissue had been down-regulated compared to control group using immunohistochemistry. Confirmed by qRT-PCR and western blot assays, results showed that SiNPs inhibited the calcium signaling pathway and cardiac muscle contraction via the down-regulated of related genes, such as ATPase-related genes (atp2a1l, atp1b2b, atp1a3b), calcium channel-related genes (cacna1ab, cacna1da) and the regulatory gene tnnc1a for cardiac troponin C. Moreover, the protein level of TNNT2 was decreased in a dose-dependent manner. For the first time, our results demonstrated that SiNPs induced cardiac dysfunction via the neutrophil-mediated cardiac inflammation and cardiac contraction in zebrafish embryos. PMID:26551753

    Emerging evidence suggests that mammalian hearts maintain the capacity for cardiac regeneration. Rapid and sensitive identification of cardiac cellular proliferation is prerequisite for understanding the underlying mechanisms and strategies of cardiac regeneration. The following immunologically related markers of cardiac cells were analyzed: cardiac transcription factors Nkx2.5 and Gata 4; specific marker of cardiomyocytes TnT; endothelial cell marker CD31; vascular smooth muscle marker smooth muscle myosin IgG; cardiac resident stem cells markers IsL1, Tbx18, and Wt1. Markers were co-localized in cardiac tissues of embryonic, neonatal, adult, and pathological samples by 5-ethynyl-2'-deoxyuridine (EdU) staining. EdU was also used to label isolated neonatal cardiomyocytes in vitro. EdU robustly labeled proliferating cells in vitro and in vivo, co-immunostaining with different cardiac cells markers. EdU can rapidly and sensitively label proliferating cardiac cells in developmental and pathological states. Cardiac cell proliferation assessed by EdU is a novel analytical tool for investigating the mechanism and strategies of cardiac regeneration in response to injury. PMID:25480318

    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

    Urinary liver-type fatty acid-binding protein (L-FABP) reflects the degree of stress in proximal tubules of the kidney. We examined the level of L-FABP in type-2 diabetes mellitus (T2DM) patients with chronic kidney disease (CKD) stage G1 and G2, and its relationship with cardiac markers and electrocardiographic (ECG) abnormalities. T2DM patients whose estimated glomerular filtration rate (eGFR) was ≥60 mL/min/1.73 m(2) were recruited [n = 276 (165 males), mean age 64 years]. The median level of urinary L-FABP was 6.6 μg/gCr. Urinary L-FABP showed significant correlation with urinary albumin-to-creatinine ratio (ACR) (r = 0.51, p L-FABP ≤8.4 μg/gCr and ACR ≤30 mg/gCr; group 2, L-FABP ≤8.4 μg/gCr and ACR >30 mg/gCr; group 3, L-FABP >8.4 μg/gCr and ACR ≤30 mg/gCr; group 4, L-FABP >8.4 μg/gCr and ACR >30 mg/gCr). Compared with group 1, group 4 was significantly higher in systolic blood pressure, and eGFR using standardized serum cystatin C, high-sensitivity troponin T, and N-terminal pro-brain natriuretic peptide (NT-proBNP). Group 4 had significantly higher level of NT-proBNP than group 3. Groups 2, 3 and 4 showed more ECG abnormalities than group 1. These findings suggest that simultaneous measurement of urinary L-FABP and ACR should be useful to assess cardiovascular damage reflecting on the elevation of cardiac markers and ECG abnormalities in T2DM with CKD G1 and G2.

    We assessed the influence of SODB, a melon superoxide dismutase (SOD), on left ventricular (LV) hypertrophy in SHR. SODB (4 or 40U SOD) was given orally for 4 or 28 days to SHR. For each treatment period, LV weight index (LVWI) and cardiomyocytes size were measured. SOD, glutathione peroxidase (GPx) and catalase expressions, and LV production and presence of superoxide anion were determined. Pro-inflammatory markers were also measured. SODB reduced LVWI and cardiomyocytes size after 4 or 28 days. Cardiac SOD and GPx increased by 30-40% with SODB. The presence but not production of superoxide anion was significantly reduced by SODB. No effect of SODB was detected on inflammatory status in any group. The beneficial effect of SODB on cardiac hypertrophy seems to be related to the stimulation of endogenous antioxidant defense, suggesting that SODB may be of interest as a dietary supplementation during conventional antihypertensive therapy.

    Full Text Available Abstract Background Cardiac inflammation and generation of oxidative stress are known to contribute to trastuzumab (herceptin induced cardiac toxicity. Toll-like receptors (TLRs are a part of the innate immune system and are involved in cardiac stress reactions. Since TLR4 might play a relevant role in cardiac inflammatory signaling, we investigated whether or not TLR4 is involved in trastuzumab induced cardiotoxicity. Methods Seven days after a single injection of herceptin (2 mg/kg; i.p., left ventricular pressure volume loops were measured in HeN compotent (TLR4+/+ and HeJ mutant (TLR4-/- treated with trastuzumab and control mice.

    Chamomile is a medicinal plant, which presents several biological effects, especially the anti-inflammatory effect. One of the compounds related to this effect is apigenin, a flavonoid that is mostly found in its glycosylated form, apigenin-7-glucoside (APG), in natural sources. However, the affectivity and safety of this glycoside have not been well explored for topical application. In this context, the aim of this work was to develop and validate a reversed-phase high-performance liquid chromatography (RP-HPLC-DAD) method to quantify APG in chamomile preparations. Additionally, the safety and the anti-inflammatory potential of this flavonoid were verified. The RP-HPLC-DAD method was developed and validated with linearity at 24.0-36.0 μg/mL range (r = 0.9994). Intra- and interday precision (RSD) were 0.27-2.66% and accuracy was 98.27-101.21%. The validated method was applied in the analysis of chamomile flower heads, glycolic extract, and Kamillen cream, supporting the method application in the quality control of chamomile preparations. Furthermore, the APG safety was assessed by MTT cytotoxicity assay and mutagenic protocols and the anti-inflammatory activity was confirmed by a diminished TNF-α production showed by mice macrophages treated with APG following LPS treatment.

  13. Molecular profiling of multiple human cancers defines an inflammatory cancer-associated molecular pattern and uncovers KPNA2 as a uniform poor prognostic cancer marker.

    Saleh M Rachidi

    Full Text Available BACKGROUND: Immune evasion is one of the recognized hallmarks of cancer. Inflammatory responses to cancer can also contribute directly to oncogenesis. Since the immune system is hardwired to protect the host, there is a possibility that cancers, regardless of their histological origins, endow themselves with a common and shared inflammatory cancer-associated molecular pattern (iCAMP to promote oncoinflammation. However, the definition of iCAMP has not been conceptually and experimentally investigated. METHODS AND FINDINGS: Genome-wide cDNA expression data was analyzed for 221 normal and 324 cancer specimens from 7 cancer types: breast, prostate, lung, colon, gastric, oral and pancreatic. A total of 96 inflammatory genes with consistent dysregulation were identified, including 44 up-regulated and 52 down-regulated genes. Protein expression was confirmed by immunohistochemistry for some of these genes. The iCAMP contains proteins whose roles in cancer have been implicated and others which are yet to be appreciated. The clinical significance of many iCAMP genes was confirmed in multiple independent cohorts of colon and ovarian cancer patients. In both cases, better prognosis correlated strongly with high CXCL13 and low level of GREM1, LOX, TNFAIP6, CD36, and EDNRA. An "Inflammatory Gene Integrated Score" was further developed from the combination of 18 iCAMP genes in ovarian cancer, which predicted overall survival. Noticeably, as a selective nuclear import protein whose immuno-regulatory function just begins to emerge, karyopherin alpha 2 (KPNA2 is uniformly up-regulated across cancer types. For the first time, the cancer-specific up-regulation of KPNA2 and its clinical significance were verified by tissue microarray analysis in colon and head-neck cancers. CONCLUSION: This work defines an inflammatory signature shared by seven epithelial cancer types and KPNA2 as a consistently up-regulated protein in cancer. Identification of iCAMP may not only

    2009-05-01

    Full Text Available Background: In a substantial portion of patients (= 25% with coronary heart disease (CHD, a myocardial infarction or sudden cardiac death without prior symptoms is the first manifestation of disease. The use of new risk predictors for CHD such as the high-sensitivity C-reactive Protein (hs-CRP in addition to established risk factors could improve prediction of CHD. As a consequence of the altered risk assessment, modified preventive actions could reduce the number of cardiac death and non-fatal myocardial infarction. Research question: Does the additional information gained through the measurement of hs-CRP in asymptomatic patients lead to a clinically relevant improvement in risk prediction as compared to risk prediction based on traditional risk factors and is this cost-effective? Methods: A literature search of the electronic databases of the German Institute of Medical Documentation and Information (DIMDI was conducted. Selection, data extraction, assessment of the study-quality and synthesis of information was conducted according to the methods of evidence-based medicine. Results: Eight publications about predictive value, one publication on the clinical efficacy and three health-economic evaluations were included. In the seven study populations of the prediction studies, elevated CRP-levels were almost always associated with a higher risk of cardiovascular events and non-fatal myocardial infarctions or cardiac death and severe cardiovascular events. The effect estimates (odds ratio (OR, relative risk (RR, hazard ratio (HR, once adjusted for traditional risk factors, demonstrated a moderate, independent association between hs-CRP and cardiac and cardiovascular events that fell in the range of 0.7 to 2.47. In six of the seven studies, a moderate increase in the area under the curve (AUC could be detected by adding hs-CRP as a predictor to regression models in addition to established risk factors though in three cases this was not

  16. Indeterminacy of Spatiotemporal Cardiac Alternans

    CERN Document Server

    2007-01-01

    Cardiac alternans, a beat-to-beat alternation in action potential duration (at the cellular level) or in ECG morphology (at the whole heart level), is a marker of ventricular fibrillation, a fatal heart rhythm that kills hundreds of thousands of people in the US each year. Investigating cardiac alternans may lead to a better understanding of the mechanisms of cardiac arrhythmias and eventually better algorithms for the prediction and prevention of such dreadful diseases. In paced cardiac tissue, alternans develops under increasingly shorter pacing period. Existing experimental and theoretical studies adopt the assumption that alternans in homogeneous cardiac tissue is exclusively determined by the pacing period. In contrast, we find that, when calcium-driven alternans develops in cardiac fibers, it may take different spatiotemporal patterns depending on the pacing history. Because there coexist multiple alternans solutions for a given pacing period, the alternans pattern on a fiber becomes unpredictable. Usin...

    The effect of Sunphenon and Polyphenon 60 in oxidative stress response, myogenic regulatory factors, inflammatory cytokines, apoptotic and proteolytic pathways on H2O2-induced myotube atrophy was addressed. Cellular responses of H2O2-induced C2C12cells were examined, including mRNA expression of myogenic regulatory factors, such as MyoD and myogenin, inflammatory pathways, such as TNF- and NF-kB, as well as proteolytic enzymes, such as -calpain and m-calpain. The pre-treatment of Sunphenon (50 g/mL)/Polyphenon 60 (50 g/mL) on H2O2-treated C2C12 cells significantly down-regulated the mRNA expression of myogenin and MyoD when compared to those treated with H2O2-induced alone. Additionally, the mRNA expression of -calpain and m-calpain were significantly ( < 0.05) increased in H2O2-treated C2C12 cells, whereas pre-treatment with Sunphenon/Polyphenon significantly down-regulated the above genes, namely -calpain and m-calpain. Furthermore, the mRNA expression of TNF- and NF-kB were significantly increased in H2O2-treated C2C12 cells, while pre-treatment with Sunphenon (50 g/mL)/Polyphenon 60 (50 g/mL) significantly ( < 0.05) down-regulated it when compared to the untreated control group. Subsequent analysis of DNA degeneration and caspase activation revealed that Sunphenon (50 g/mL)/Polyphenon 60 (50 g/mL) inhibited activation of caspase-3 and showed an inhibitory effect on DNA degradation. From this result, we know that, in stress conditions, -calpain may be involved in the muscle atrophy through the suppression of myogenin and MyoD. Moreover, Sunphenon may regulate the skeletal muscle genes/promote skeletal muscle recovery by the up-regulation of myogenin and MyoD and suppression of -calpain and inflammatory pathways and may regulate the apoptosis pathways. Our findings suggest that dietary supplementation of Sunphenon might reduce inflammatory events in muscle-associated diseases, such as myotube atrophy.

    N-Acetyl-p-Aminophenol (APAP), also known as acetaminophen, is the most commonly used over-the counter analgesic and antipyretic medication. However, its overdose leads to both liver and kidney damage. APAP-induced toxicity is considered as one of the primary causes of acute liver failure; numerous scientific reports have focused majorly on APAP hepatotoxicity. Alternatively, not many works approach APAP nephrotoxicity focusing on both its mechanisms of action and therapeutic exploration. Moringa oleifera (MO) is pervasive in nature, is reported to possess a surplus amount of nutrients, and is enriched with several bioactive candidates including trace elements that act as curatives for various clinical conditions. In this study, we evaluated the nephro-protective potential of MO leaf extract against APAP nephrotoxicity in male Balb/c mice. A single-dose acute oral toxicity design was implemented in this study. Group 2, 3, 4 and 5 received a toxic dose of APAP (400 mg/kg of bw, i.p) and after an hour, these groups were administered with saline (10 mL/kg), silymarin-positive control (100 mg/kg of bw, i.p), MO leaf extract (100 mg/kg of bw, i.p), and MO leaf extract (200 mg/kg bw, i.p) respectively. Group 1 was administered saline (10 mL/kg) during both the sessions. APAP-treated mice exhibited a significant elevation of serum creatinine, blood urea nitrogen, sodium, potassium and chloride levels. A remarkable depletion of antioxidant enzymes such as SOD, CAT and GSH-Px with elevated MDA levels has been observed in APAP treated kidney tissues. They also exhibited a significant rise in pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and decreased anti-inflammatory (IL-10) cytokine level in the kidney tissues. Disorganized glomerulus and dilated tubules with inflammatory cell infiltration were clearly observed in the histology of APAP treated mice kidneys. All these pathological changes were reversed in a dose-dependent manner after MO leaf extract treatment

    /FA1 in insulin resistance and type 2 diabetes in human subjects, we studied the effects of chronic FA1 on the intermediary metabolism in myotubes established from lean, obese, and type 2 diabetic (T2D) subjects. Methods: Myotube cultures were established from lean and obese control subjects, and...... established from lean, obese, and T2D subjects. Instead, chronic FA1 exposure induced pro-inflammatory cytokines expression (IL-6 and CCL2) in association with reducing adipogenic markers (ADD1, AP2, CD36, and PPARg2) in myotubes. Consistent with this observation, addition of FA1 to cultured myotubes was show...... to significantly inhibit their differentiation into adipocyte. Conclusion: Our results exclude direct effects of FA1 on glucose and lipid metabolism in cultured myotubes established from lean, obese, and T2D subjects. Therefore, the pathogenesis of FA1-induced IR might mainly be mediated via the FA1...

    Full Text Available This study evaluates the cardioprotective effect of esculetin on isoproterenol (ISO-induced myocardial infarction (MI in rats. Rats were pretreated with esculetin (10 and 20 mg/kg orally for a period of 21 days. After the treatment period ISO (85 mg/kg was administered subcutaneously to rats at an interval of 24 h for 2 days. ISO-induced rats showed a significant increase in the activities of marker enzymes such as creatine kinase (CK, creatine kinase-MB (CK-MB, aspartate transaminase (AST, alanine transaminase (ALT, and lactate dehydrogenase (LDH in serum and there by subsequent decrease in the heart, and also ISO-induced rats showed a significant increase in heart weight. A significant decrease in the activity of sodium/potassium dependent adenosine triphosphatase (Na+/K+-ATPase and increased in the activities of calcium and magnesium dependent adenosine triphosphatase (Ca2+ and Mg2+-ATPase were observed in the heart of ISO-induced rats. Pretreatment with esculetin positively altered the activities of marker enzymes and the biochemical parameters in ISO-induced rats. Thus, our study shows that esculetin posses cardioprotective effect in ISO-induced MI in rats. Results obtained from histopathological studies also supported that esculetin has preventive effect against ISO-induced myocardial infarction.

    We aimed to determine the effects of an 8 wk Hatha yoga training on blood glucose, insulin, lipid profiles, endothelial microparticles (EMPs), and inflammatory status in healthy, lean, and female Chinese subjects. A total of 30 healthy, female Chinese subjects were recruited and randomized into control or yoga practice group. The yoga practice included 8 wks of yoga practice (2 times/wk) for a total of 16 times. Fasting blood samples were collected before and after yoga training. Plasma was isolated for the measurement of lipid profiles, glucose, insulin, EMPs, and inflammatory cytokines. Whole blood was cultured ex vivo and stimulated with lipopolysaccharide (LPS) and Pam3Cys-SK4. Peripheral blood mononuclear cells (PBMCs) were isolated for the measurement of TLR2 and TLR4 protein expression. Yoga practice significantly reduced plasma cholesterol, LDL-cholesterol, insulin levels, and CD31+/CD42b− EMPs. Cultured whole blood from the yoga group has reduced proinflammatory cytokines secretion both at unstimulated condition and when stimulated with Pam3Cys-SK4; this might be associated with reduced TLR2 protein expression in PBMCs after yoga training. Hatha yoga practice in healthy Chinese female subjects could improve hallmarks related to MetS; thus it can be considered as an ancillary intervention in the primary MetS prevention for the healthy population. This trial is registered with ChiCTR-IOR-14005747.

    Uveitis is one of the major diagnostic criteria of Behçet's disease (BD), a chronic systemic inflammatory pathology with an uncertain etiology. Since uveitis is more frequent in male patients, we assessed the level and the effect of sex hormones on inflammatory responses during BD. Peripheral blood was taken from 19 patients with BD and 20 healthy subjects. Estradiol, testosterone and cortisol were measured in plasma by ELISA. Circulating mononuclear cells (PBMC) were obtained on gradient density and cultured with or without the three hormones for 24h at 37 ̊C. IL-12 and nitric oxide (NO) were measured in vivo and ex vivo by ELISA and a modified Griess method, respectively. We confirmed the significantly higher in vivo and in vitro levels of NO and IL-12 in BD in comparison to controls (P0.05). In vitro, NO was reduced by estradiol and cortisol and increased by testosterone in both sexes. In contrast, while IL-12 production showed the same production profile as NO in women, estradiol and cortisol failed to reduce IL-12 levels in men. Our results may explain in part the differences observed between men and women in disease clinical expression. In fact, male patients seem to have defective IL-12 down-regulation by estradiol and cortisol that increases Th1 immune responses. This may be implicated in the severe expression of BD in men.

  8. Expression of proliferative and inflammatory markers in a full-thickness human skin equivalent following exposure to the model sulfur mustard vesicant, 2-chloroethyl ethyl sulfide

    International Nuclear Information System (INIS)

    Sulfur mustard is a potent vesicant that induces inflammation, edema and blistering following dermal exposure. To assess molecular mechanisms mediating these responses, we analyzed the effects of the model sulfur mustard vesicant, 2-chloroethyl ethyl sulfide, on EpiDerm-FTTM, a commercially available full-thickness human skin equivalent. CEES (100-1000 μM) caused a concentration-dependent increase in pyknotic nuclei and vacuolization in basal keratinocytes; at high concentrations (300-1000 μM), CEES also disrupted keratin filament architecture in the stratum corneum. This was associated with time-dependent increases in expression of proliferating cell nuclear antigen, a marker of cell proliferation, and poly(ADP-ribose) polymerase (PARP) and phosphorylated histone H2AX, markers of DNA damage. Concentration- and time-dependent increases in mRNA and protein expression of eicosanoid biosynthetic enzymes including COX-2, 5-lipoxygenase, microsomal PGE2 synthases, leukotriene (LT) A4 hydrolase and LTC4 synthase were observed in CEES-treated skin equivalents, as well as in antioxidant enzymes, glutathione S-transferases A1-2 (GSTA1-2), GSTA3 and GSTA4. These data demonstrate that CEES induces rapid cellular damage, cytotoxicity and inflammation in full-thickness skin equivalents. These effects are similar to human responses to vesicants in vivo and suggest that the full thickness skin equivalent is a useful in vitro model to characterize the biological effects of mustards and to develop potential therapeutics.

    Full Text Available Adipose-derived stem cells (ADSCs have the potential to differentiate into various cell lineages and they are easily obtainable from patients, which makes them a promising candidate for cell therapy. However, a drawback is their limited life span during in vitro culture. Therefore, hTERT-immortalized CD34+ and CD34- mouse ADSC lines (mADSCshTERT tagged with GFP were established. We evaluated the proliferation capacity, multi-differentiation potential, and secretory profiles of CD34+ and CD34- mADSCshTERT in vitro, as well as their effects on cardiac function and systemic inflammation following transplantation into a rat model of acute myocardial infarction (AMI to assess whether these cells could be used as a novel cell source for regeneration therapy in the cardiovascular field. CD34+ and CD34- mADSCshTERT demonstrated phenotypic characteristics and multi-differentiation potentials similar to those of primary mADSCs. CD34+ mADSCshTERT exhibited a higher proliferation ability compared to CD34- mADSCshTERT, whereas CD34- mADSCshTERT showed a higher osteogenic differentiation potential compared to CD34+ mADSCshTERT. Primary mADSCs, CD34+, and CD34- mADSCshTERT primarily secreted EGF, TGF-β1, IGF-1, IGF-2, MCP-1, and HGFR. CD34+ mADSCshTERT had higher secretion of VEGF and SDF-1 compared to CD34- mADSCshTERT. IL-6 secretion was severely reduced in both CD34+ and CD34- mADSCshTERT compared to primary mADSCs. Transplantation of CD34+ and CD34- mADSCshTERT significantly improved the left ventricular ejection fraction and reduced infarct size compared to AMI-induced rats after 28 days. At 28 days after transplantation, engraftment of CD34+ and CD34- mADSCshTERT was confirmed by positive Y chromosome staining, and differentiation of CD34+ and CD34- mADSCshTERT into endothelial cells was found in the infarcted myocardium. Significant decreases were observed in circulating IL-6 levels in CD34+ and CD34- mADSCshTERT groups compared to the AMI

    Background. We tested the hypothesis that high intensity interval training (HIIT) would be more effective than moderate intensity continuous training (MIT) to improve newly emerged markers of cardiorespiratory fitness in coronary heart disease (CHD) patients, as the relationship between ventilation and carbon dioxide production (VE/VCO2 slope), oxygen uptake efficiency slope (OUES), and oxygen pulse (O2P). Methods. Seventy-one patients with optimized treatment were randomly assigned into HIIT (n = 23, age = 56 ± 12 years), MIT (n = 24, age = 62 ± 12 years), or nonexercise control group (CG) (n = 24, age = 64 ± 12 years). MIT performed 30 min of continuous aerobic exercise at 70–75% of maximal heart rate (HRmax), and HIIT performed 30 min sessions split in 2 min alternate bouts at 60%/90% HRmax (3 times/week for 16 weeks). Results. No differences among groups (before versus after) were found for VE/VCO2 slope or OUES (P > 0.05). After training the O2P slope increased in HIIT (22%, P 0.05), while decreased in CG (−20%, P HIIT (P = 0.03). Conclusion. HIIT was more effective than MIT for improving O2P slope in CHD patients, while VE/VCO2 slope and OUES were similarly improved by aerobic training regimens versus controls. PMID:25741531

    We evaluated maternal flaxseed oil intake during lactation on body composition, lipid profile, glucose homeostasis and adipose tissue inflammation in male and female progeny at adulthood. Lactating rats were divided into the following: control 7% soybean oil (C), hyper 19% soybean oil (HS) and hyper 17% flaxseed oil+2% soybean oil (HF). Weaned pups received a standard diet. Offspring were killed in PN180. Male HF presented higher visceral adipose tissue (VAT) and triacylglycerol, and female HF showed insulin resistance. Both male and female HF had hyperleptinemia, and only male HF had hyperprolactinemia. In VAT, male HF presented lower PPAR-γ expressions and higher TNF-α, IL-6, IL-1β and IL-10 expressions; in subcutaneous adipose tissue (SAT), they presented lower PPAR-γ and TNF-α expressions. Female HF presented higher leptin, as well as lower adiponectin, TNF-α, IL-6 and IL-1β expressions in VAT and lower TNF-α in SAT. Flaxseed oil during lactation leads to gender-specific effects with more adiposity and dyslipidemia in male and insulin resistance in female. Higher prolactin and inflammatory cytokines in male could play a role in these gender differences. We suggest that the use of flaxseed oil during lactation increases metabolic syndrome risk in the adult progeny. PMID:27469994

    Full Text Available Obesity characterized by increased mass of adipose tissue leads to systemic inflammation. Calorie restriction (CR improves parameters associated with immune response and antioxidant defense. We hypothesized that CR with a high fat diet (HFCR regulates local and systemic inflammation and oxidative stress damage in a high fat diet induced obesity (HF group. We investigated effect of HFCR on inflammation and oxidative stress-related markers in liver and adipose tissues as well as adipokines in plasma. HFCR lowered liver triglyceride levels, total cholesterol levels, and the plasma leptin/adiponectin ratio to normal levels and improved glucose tolerance. HFCR also improved fatty liver and normalized adipocyte size and morphology. HFCR reduced lipid peroxidation and decreased the expression levels of inducible nitric oxide synthetase, cyclooxygenase-2, NF-E2-related factor, and heme oxygenase-1 in the liver. Moreover, HFCR suppressed the expression levels of C- reactive protein and manganese superoxide dismutase in the adipose tissue in the HF group. These results suggest that HFCR may have beneficial effects on inflammation and oxidative stress as well as lipid profiles in the HF diet induced obesity. Moreover, HFCR may be a good way to increase compliance in obese patients and to prevent obesity induced complications without changes in dietary pattern.

    Full Text Available Abstract Background Two decades after the introduction of oil-based vaccines in the control of bacterial and viral diseases in farmed salmonids, the mechanisms of induced side effects manifested as intra-abdominal granulomas remain unresolved. Side effects have been associated with generation of auto-antibodies and autoimmunity but the underlying profile of inflammatory and immune response has not been characterized. This study was undertaken with the aim to elucidate the inflammatory and immune mechanisms of granuloma formation at gene expression level associated with high and low side effect (granuloma indices. Groups of Atlantic salmon parr were injected intraperitoneally with oil-adjuvanted vaccines containing either high or low concentrations of Aeromonas salmonicida or Moritella viscosa antigens in order to induce polarized (severe and mild granulomatous reactions. The established granulomatous reactions were confirmed by gross and histological methods at 3 months post vaccination when responses were known to have matured. The corresponding gene expression patterns in the head kidneys were profiled using salmonid cDNA microarrays followed by validation by real-time quantitative PCR (qPCR. qPCR was also used to examine the expression of additional genes known to be important in the adaptive immune response. Results Granulomatous lesions were observed in all vaccinated fish. The presence of severe granulomas was associated with a profile of up-regulation of innate immunity-related genes such as complement factors C1q and C6, mannose binding protein, lysozyme C, C-type lectin receptor, CD209, Cathepsin D, CD63, LECT-2, CC chemokine and metallothionein. In addition, TGF-β (p = 0.001, IL-17A (p = 0.007 and its receptor (IL-17AR (p = 0.009 representing TH17 were significantly up-regulated in the group with severe granulomas as were arginase and IgM.

    C-reactive protein (CRP) is a pro-inflammatory protein with potential as a biomarker in predicting colon cancer risk. However, little is known regarding its association with risk of colorectal adenomas, particularly by subtypes. We conducted a colonoscopy-based matched case-control study to assess whether elevated plasma CRP levels may be associated with colorectal adenoma risk and further whether this association may be modified by urinary prostaglandin E2 metabolite (PGE-M), a biomarker of systemic prostaglandin E2 production. Included in the study were 226 cases with a single small tubular adenoma, 198 cases with multiple small tubular adenomas, 283 cases with at least one advanced adenoma, and 395 polyp-free controls. No apparent association between CRP level and risk of single small tubular adenomas was found (ptrend  = 0.59). A dose-response relationship with CRP level was observed for risk of either multiple small tubular adenomas (OR = 2.01, 95%CI = 1.10-3.68 for the highest versus lowest tertile comparison; ptrend   = 0.03) or advanced adenomas (OR = 1.81, 95%CI = 1.10-2.96 for the highest versus lowest tertile comparison; ptrend  = 0.02). In a joint analysis of CRP level and PGE-M, risk of multiple or advanced adenoma was greatest among those with highest levels of both CRP and PGE-M in comparison to those with low CRP and low PGE-M (OR = 3.72, 95%CI = 1.49-9.72). Our results suggest that elevated CRP, particularly in the context of concurrent elevated PGE-M, may be a biomarker of multiple or advanced adenoma risk in a screening age population. © 2015 Wiley Periodicals, Inc.

    Multi-walled carbon nanotubes (MWCNTs) are an inhomogeneous group of nanomaterials that vary in lengths, shapes and types of metal contamination, which makes hazard evaluation difficult. Here we present a toxicogenomic analysis of female C57BL/6 mouse lungs following a single intratracheal instillation of 0, 18, 54 or 162 μg/mouse of a small, curled (CNT{sub Small}, 0.8 ± 0.1 μm in length) or large, thick MWCNT (CNT{sub Large}, 4 ± 0.4 μm in length). The two MWCNTs were extensively characterized by SEM and TEM imaging, thermogravimetric analysis, and Brunauer–Emmett–Teller surface area analysis. Lung tissues were harvested 24 h, 3 days and 28 days post-exposure. DNA microarrays were used to analyze gene expression, in parallel with analysis of bronchoalveolar lavage fluid, lung histology, DNA damage (comet assay) and the presence of reactive oxygen species (dichlorodihydrofluorescein assay), to profile and characterize related pulmonary endpoints. Overall changes in global transcription following exposure to CNT{sub Small} or CNT{sub Large} were similar. Both MWCNTs elicited strong acute phase and inflammatory responses that peaked at day 3, persisted up to 28 days, and were characterized by increased cellular influx in bronchoalveolar lavage fluid, interstitial pneumonia and gene expression changes. However, CNT{sub Large} elicited an earlier onset of inflammation and DNA damage, and induced more fibrosis and a unique fibrotic gene expression signature at day 28, compared to CNT{sub Small}. The results indicate that the extent of change at the molecular level during early response phases following an acute exposure is greater in mice exposed to CNT{sub Large}, which may eventually lead to the different responses observed at day 28. - Highlights: • We evaluate the toxicogenomic response in mice following MWCNT instillation. • Two MWCNTs of different properties were examined and thoroughly characterized. • MWCNT exposure leads to increased pulmonary

    Full Text Available Abstract Background Duchenne muscular dystrophy (DMD is an inherited and progressive disease causing striated muscle deterioration. Patients in their twenties generally die from either respiratory or cardiac failure. In order to improve the lifespan and quality of life of DMD patients, it is important to prevent or reverse the progressive loss of contractile function of the heart. Recent studies by our labs have shown that the peptide NBD (Nemo Binding Domain, targeted at blunting Nuclear Factor κB (NF-κB signaling, reduces inflammation, enhances myofiber regeneration, and improves contractile deficits in the diaphragm in dystrophin-deficient mdx mice. Methods To assess whether cardiac function in addition to diaphragm function can be improved, we investigated physiological and histological parameters of cardiac muscle in mice deficient for both dystrophin and its homolog utrophin (double knockout = dko mice treated with NBD peptide. These dko mice show classic pathophysiological hallmarks of heart failure, including myocyte degeneration, an impaired force-frequency response and a severely blunted β-adrenergic response. Cardiac contractile function at baseline and frequencies and pre-loads throughout the in vivo range as well as β-adrenergic reserve was measured in isolated cardiac muscle preparations. In addition, we studied histopathological and inflammatory markers in these mice. Results At baseline conditions, active force development in cardiac muscles from NBD treated dko mice was more than double that of vehicle-treated dko mice. NBD treatment also significantly improved frequency-dependent behavior of the muscles. The increase in force in NBD-treated dko muscles to β-adrenergic stimulation was robustly restored compared to vehicle-treated mice. However, histological features, including collagen content and inflammatory markers were not significantly different between NBD-treated and vehicle-treated dko mice. Conclusions We conclude

    This study investigates the possible protective effects of montelukast (MNT) against lipopolysaccharide (LPS)-induced cardiac injury, in comparison to dexamethasone (DEX), a standard anti-inflammatory. Male Sprague Dawley rats (160-180 g) were assigned to five groups (n = 8/group): (1) control; (2) LPS (10 mg/kg, intraperitoneal (i.p.)); (3) LPS + MNT (10 mg/kg, per os (p.o.)); (4) LPS + MNT (20 mg/kg, p.o.); and (5) LPS + DEX (1 mg/kg, i.p.). Twenty-four hours after LPS injection, heart/body weight (BW) ratio and percent survival of rats were determined. Serum total protein, creatine kinase muscle/brain (CK-MB), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) activities were measured. Heart samples were taken for histological assessment and for determination of malondialdehyde (MDA) and glutathione (GSH) contents. Cardiac tumor necrosis factor α (TNF-α) expression was evaluated immunohistochemically. LPS significantly increased heart/BW ratio, serum CK-MB, ALP, and LDH activities and decreased percent survival and serum total protein levels. MDA content increased in heart tissues with a concomitant reduction in GSH content. Immunohistochemical staining of heart specimens from LPS-treated rats revealed high expression of TNF-α. MNT significantly reduced percent mortality and suppressed the release of inflammatory and oxidative stress markers when compared with LPS group. Additionally, MNT effectively preserved tissue morphology as evidenced by histological evaluation. MNT (20 mg/kg) was more effective in alleviating LPS-induced heart injury when compared with both MNT (10 mg/kg) and DEX (1 mg/kg), as evidenced by decrease in positive staining by TNF-α immunohistochemically, decrease MDA, and increase GSH content in heart tissue. This study demonstrates that MNT might have cardioprotective effects against the inflammatory process during endotoxemia. This effect can be attributed to its antioxidant and/or anti-inflammatory properties. PMID:26089034

    Lung ischemia-reperfusion (IR) complicates numerous clinical processes, such as cardiac arrest, transplantation, and major trauma. These conditions generate sterile inflammation, which can cause or worsen acute lung injury. We previously reported that lung and systemic inflammation in a mouse model of ventilated lung IR depends on Toll-like receptor 4 (TLR-4) signaling and the presence of alveolar macrophages. Here, we tested the hypothesis that the intestinal microbiome has a role in influencing the inflammatory response to lung IR. Lung IR was created in intubated mechanically ventilated mice via reversible left pulmonary artery occlusion followed by reperfusion. Inflammatory markers and histology were tracked during varying periods of reperfusion (from 1 to 24 h). Separate groups of mice were given intestinally localized antibiotics for 8 to 10 weeks and then were subjected to left lung IR and analysis of lungs and plasma for markers of inflammation. Alveolar macrophages from antibiotic-treated or control mice were tested ex vivo for inflammatory responses to bacterial TLR agonists, namely, lipopolysaccharide and Pam3Cys. We found that inflammation generated by left lung IR was rapid in onset and dissipated within 12 to 24 h. Treatment of mice with intestinally localized antibiotics was associated with a marked attenuation of circulating and lung inflammatory markers as well as reduced histologic evidence of infiltrating cells and edema in the lung after IR. Alveolar macrophages from antibiotic-treated mice produced less cytokines ex vivo when stimulated with TLR agonists as compared with those from control mice. Our data indicate that the inflammatory response induced by nonhypoxic lung IR is transient and is strongly influenced by intestinal microbiota. Furthermore, these data suggest that the intestinal microbiome could potentially be manipulated to attenuate the post-IR pulmonary inflammatory response. PMID:26196836

    Patients undergoing cardiac surgery with extracorporeal circulation (EC) frequently develop a systemic inflammatory response syndrome. Surgical trauma, ischaemia-reperfusion injury, endotoxaemia and blood contact to nonendothelial circuit compounds promote the activation of coagulation pathways, complement factors and a cellular immune response. This review discusses the multiple pathways leading to endothelial cell activation, neutrophil recruitment and production of reactive oxygen species and nitric oxide. All these factors may induce cellular damage and subsequent organ injury. Multiple organ dysfunction after cardiac surgery with EC is associated with an increased morbidity and mortality. In addition to the pathogenesis of organ dysfunction after EC, this review deals with different therapeutic interventions aiming to alleviate the inflammatory response and consequently multiple organ dysfunction after cardiac surgery.

    Understanding the mutual relationship between the liver and the heart is important for both hepatologists and cardiologists. Hepato-cardiac diseases can be classified into heart diseases affecting the liver, liver diseases affecting the heart, and conditions affecting the heart and the liver at the same time. Differential diagnoses of liver injury are extremely important in a cardiologist’s clinical practice calling for collaboration between cardiologists and hepatologists due to the many other diseases that can affect the liver and mimic haemodynamic injury. Acute and chronic heart failure may lead to acute ischemic hepatitis or chronic congestive hepatopathy. Treatment in these cases should be directed to the primary heart disease. In patients with advanced liver disease, cirrhotic cardiomyopathy may develop including hemodynamic changes, diastolic and systolic dysfunctions, reduced cardiac performance and electrophysiological abnormalities. Cardiac evaluation is important for patients with liver diseases especially before and after liver transplantation. Liver transplantation may lead to the improvement of all cardiac changes and the reversal of cirrhotic cardiomyopathy. There are systemic diseases that may affect both the liver and the heart concomitantly including congenital, metabolic and inflammatory diseases as well as alcoholism. This review highlights these hepatocardiac diseases

    Inflammatory pseudotumor of the lung was first described by Brunn in 1939. Since that description, various extrapulmonary sites of inflammatory pseudotumor have been described. Review of the literature reveals five cases of inflammatory pseudotumor involving the heart, but no cases have been reported in the radiology literature. The present case involves a 7-month-old girl with inflammatory pseudotumor involving the right atrium, which was completely excised at surgery. Though rare, inflammatory pseudotumor should be considered in the differential diagnosis of cardiac tumors in children. (orig.)

    Shimizu, Ippei; Minamino, Tohru

    2016-08-01

    The heart must continuously pump blood to supply the body with oxygen and nutrients. To maintain the high energy consumption required by this role, the heart is equipped with multiple complex biological systems that allow adaptation to changes of systemic demand. The processes of growth (hypertrophy), angiogenesis, and metabolic plasticity are critically involved in maintenance of cardiac homeostasis. Cardiac hypertrophy is classified as physiological when it is associated with normal cardiac function or as pathological when associated with cardiac dysfunction. Physiological hypertrophy of the heart occurs in response to normal growth of children or during pregnancy, as well as in athletes. In contrast, pathological hypertrophy is induced by factors such as prolonged and abnormal hemodynamic stress, due to hypertension, myocardial infarction etc. Pathological hypertrophy is associated with fibrosis, capillary rarefaction, increased production of pro-inflammatory cytokines, and cellular dysfunction (impairment of signaling, suppression of autophagy, and abnormal cardiomyocyte/non-cardiomyocyte interactions), as well as undesirable epigenetic changes, with these complex responses leading to maladaptive cardiac remodeling and heart failure. This review describes the key molecules and cellular responses involved in physiological/pathological cardiac hypertrophy. PMID:27262674

  4. Prenatal Screening Using Maternal Markers

    Directory of Open Access Journals (Sweden)

    Howard Cuckle

    2014-05-01

    Full Text Available Maternal markers are widely used to screen for fetal neural tube defects (NTDs, chromosomal abnormalities and cardiac defects. Some are beginning to broaden prenatal screening to include pregnancy complications such as pre-eclampsia. The methods initially developed for NTDs using a single marker have since been built upon to develop high performance multi-maker tests for chromosomal abnormalities. Although cell-free DNA testing is still too expensive to be considered for routine application in public health settings, it can be cost-effective when used in combination with existing multi-maker marker tests. The established screening methods can be readily applied in the first trimester to identify pregnancies at high risk of pre-eclampsia and offer prevention though aspirin treatment. Prenatal screening for fragile X syndrome might be adopted more widely if the test was to be framed as a form of maternal marker screening.

    The major cause of death during the first year after heart transplantation is primary graft dysfunction due to preservation and ischemia-reperfusion injury (IRI). Angiopoietin-1 is a Tie2 receptor-binding paracrine growth factor with anti-inflammatory properties and indispensable roles in vascular development and stability. We used a stable variant of angiopoietin-1 (COMP-Ang1) to test whether ex vivo intracoronary treatment with a single dose of COMP-Ang1 in donor Dark Agouti rat heart subjected to 4-h cold ischemia would prevent microvascular dysfunction and inflammatory responses in the fully allogeneic recipient Wistar Furth rat. COMP-Ang1 reduced endothelial cell-cell junction disruption of the donor heart in transmission electron microscopy during 4-h cold ischemia, improved myocardial reflow, and reduced microvascular leakage and cardiomyocyte injury of transplanted allografts during IRI. Concurrently, the treatment reduced expression of danger signals, dendritic cell maturation markers, endothelial cell adhesion molecule VCAM-1 and RhoA/Rho-associated protein kinase activation and the influx of macrophages and neutrophils. Furthermore, COMP-Ang1 treatment provided sustained anti-inflammatory effects during acute rejection and prevented the development of cardiac fibrosis and allograft vasculopathy. These results suggest donor heart treatment with COMP-Ang1 having important clinical implications in the prevention of primary and subsequent long-term injury and dysfunction in cardiac allografts.

    We investigated whether the pathways linked to Toll-like receptors 2 and 4 (TLRs) are involved in renal ischemia-reperfusion (I/R)-induced cardiac hypertrophy. Wild type (WT) C57BL/6J, TLR2-/- and TLR4-/- mice were subjected to left kidney ischemia for 60 min followed by reperfusion for 5, 8, 12 and 15 days. Proton density magnetic resonance showed alterations in the injured kidney from WT mice, together with signs of parenchymal edema and higher levels of vimentin mRNA, accompanied by: (i) small, but significant, increase in serum urea after 24 h, (ii) 100% increase in serum creatinine at 24 h. A serum peak of inflammatory cytokines occurred after 5 days of reperfusion. Heart weight/body weight and heart weight/tibia length ratios increased after 12 and 15 days of reperfusion, respectively. Cardiac hypertrophy markers, B-type natriuretic peptide (BNP) and α-actin, left ventricle mass, cardiac wall thickness and myocyte width increased after 15 days of reperfusion, together with longer QTc and action potential duration. Cardiac TLRs, MyD88, HSP60 and HSP70 mRNA levels also increased. After 15 days of reperfusion, absence of TLRs prevented cardiac hypertrophy, as reflected by similar values of left ventricular cardiac mass and heart weight/body weight ratio compared to the transgenic Sham. Renal tissular injury also ameliorated in both knockout mice, as revealed by the comparison of their vimentin mRNA levels with those found in the WT on the same day after I/R. The I/R TLR2-/- group had TNF-α, IFN-γ and IL-1β levels similar to the non-I/R group, whereas the TLR4-/- group conserved the p-NF-κB/NF- κB ratio contrasting with that found in TLR2-/-. We conclude: (i) TLRs are involved in renal I/R-induced cardiac hypertrophy; (ii) absence of TLRs prevents I/R-induced cardiac hypertrophy, despite renal lesions seeming to evolve towards those of chronic disease; (iii) TLR2 and TLR4 selectively regulate the systemic inflammatory profile and NF- κB activation.

    Full Text Available THE mechanisms responsible for development of inflammatory bowel disease (IBD have not been fully elucidated, although the main cause of disease pathology is attributed to up-regulated inflammatory processes. The aim of this study was to investigate frequencies of polymorphisms in genes encoding pro-inflammatory and anti-inflammatory markers in IBD patients and controls. We determined genotypes of patients with IBD (n=172 and healthy controls (n=389 for polymorphisms in genes encoding various cytokines (interleukin (IL-1β, IL-6, tumour necrosis factor (TNF, IL-10, IL-1 receptor antagonist. Association of these genotypes to disease incidence and pathophysiology was investigated. No strong association was found with occurrence of IBD. Variation was observed between the ulcerative colitis study group and the control population for the TNF-α-308 polymorphism (p=0.0135. There was also variation in the frequency of IL-6-174 and TNF-α-308 genotypes in the ulcerative colitis group compared with the Crohn's disease group (p=0.01. We concluded that polymorphisms in inflammatory genes are associated with variations in IBD phenotype and disease susceptibility. Whether the polymorphisms are directly involved in regulating cytokine production, and consequently pathophysiology of IBD, or serve merely as markers in linkage disequilibrium with susceptibility genes remains unclear.

    Background This study was conducted to determine the early cardiac valvular changes in young male ankylosing spondylitis (AS) patients. Methods A total of 70 AS patients on treatment without clinical cardiac symptoms were divided into group I (< 10 years, n = 50) and group II (≥ 10 years, n = 20) depending on their disease duration after first diagnosis. Twenty-five healthy volunteers were selected as control subjects. All the subjects underwent transthoracic and transesophageal echocardiography, electrocardiography, and rheumatologic evaluation for AS patients. Results The thickness of both the aortic and mitral valve was more increased in AS patients than in controls. Aortic valve thickness over 1.3 mm could predict AS with a sensitivity of 73% and specificity of 76%. The prevalence of aortic valve thickening was higher in the AS group compared to the controls. The prevalence of aortic and mitral regurgitation was very low and there was no difference between the controls and the patients. The aortic valve thickening was related to longer disease duration, high blood pressure, disease activity and inflammatory markers. Conclusion Thickening of the aortic and mitral valve was observed without regurgitation in male AS patients early in the course of their disease without clinical cardiac manifestations. This subclinical change of aorto-mitral valve in early AS should be considered and followed up to determine its prognostic implication and evolution. PMID:22509436

    Full Text Available The aim of this study was to evaluate the anti-inflammatory profiling of the Chinese herbal formula Sini Tang (SNT in myocardial infarction (MI rats. SNT, a decoction consisting of four herbs: Aconitum carmichaelii, Cinnamomum cassia, Zingiber officinale, and Glycyrrhiza uralensis, was characterized as a remedy to treat syndromes corresponding to heart failure and MI in China. Potential biomarkers, which reflect the extent of myocardial necrosis and correlate with cardiac outcomes following MI, such as atrial natriuretic peptide (ANP, high sensitivity C-reactive protein (hs-CRP, and proinflammatory cytokines such as tumor necrosis factor-α, interleukin-6, and interleukin-1β (TNF-α, IL-6, and IL-1β were determined in plasma, serum, and in myocardial tissue of MI rats after treatment with SNT. Our data indicate that SNT decreased significantly the levels of hs-CRP, TNF-α, IL-6, and IL-1β in MI rats. SNT decreased the expression of ANP levels in plasma and increased the vascular active marker nitric oxide, which limits vascular inflammation. In addition, SNT could decrease the expression of endothelin-1 levels in rat plasma post-MI. Our data suggest that the Chinese herbal formula SNT has the potential to improve cardiac function after MI. SNT may be a candidate for treating MI and its associated inflammatory responses.

    complication after a cardiac arrest. Many studies are trying to find prognostic markers that can be associated with outcomes in patients surviving a cardiac arrest. Biochemical markers of neuronal injury seem to be promising in this scenario. Therefore, NSE levels have been studied in patients after a cardiac arrest and high enzyme levels suggest more extensive brain damage and are associated with unfavorable clinical outcomes. CONCLUSIONS: Outcome after a cardiac arrest is mostly determined by the degree of hypoxic brain damage and early determinations of serum NSE level can be a valuable ancillary method for assessing outcome in these patients.

To evaluate role of inflammation in pathogenesis of cardiac autonomic dysfunction assessed by heart rate variability (HRV analyses, in patients (pts with systemic lupus erythematosus (SLE. Material and methods. 75 female pts with SLE aged before 55 years were included. Control group consisted of 32 healthy women of comparable age. Clinical symptoms, activity degree and main cardiovascular risk factors were assessed. Common carotid duplex scanning with measurement of intima-media thickness, echocardiography, 24 h ECG ambulatory recording with determination of time domain parameters, evaluation of serum inflammation markers level (CRP, IL-6, TNFa were performed. Results. HRV time domain parameters adjusted by McanNN - SDNNn%, SDNNin%, rMSSDn%, pNN50% in women with SLE were lower than in healthy control. HRV parameters inversely correlated with inflammation markers in SLE (p<0,05. SLE pts were divided into 4 groups: 1 (n=12 - pts with low HRV parameters and high level of IL-6; 2 (n=13 - low HRV and normal IL-6; 3 (n=6 - normal HRV and high IL-6; 4 (n=44 - normal HRV and IL-6. SLEDA1 2K, left atrium size, levels of markers of inflammation in group 1 were higher, then in group 4 (p<0,05. Hypertension, dyslipidemia, smoking and subclinical atherosclerosis of carotid arteries were more frequent in group 2 compared to group 4 (p<0,05. Conclusion. These results suggest important role of autoimmune inflammation in pathogenesis of cardiac autonomic dysfunction in SLE pts with high disease activity and traditional cardiovascular risk factor, atherosclerotic changes - in low SLE activity. HRV, traditional cardiovascular risk factors and inflammatory markers combined measurement can help to identify subjects at risk of cardiovascular mortality among SLE pts.

    Full Text Available Allograft rejection would entail an increase in certain blood biomarkers and active substances derived from activated inflammatory cells which could influence entire vascular endothelial function and deteriorate arterial wall stiffness. We propose that carotid wall functional indices measured with non-invasive ultrasound could we valuable markers of the subclinical cardiac allograft rejection. Aim. Our goal was to analyze the clinical utility of functional common carotid wall (CCW variables measured with high-resolution Doppler ultrasound as a non-invasive screening tool for allograft rejection in cardiac transplant patients (pts. Methods. One hundred and seventy one pts included 93 cardiac recipients, 30 dilated cardiomyopathy waiting list pts, and 48 stable coronary artery disease (SCAD pts without decompensated heart failure were included. Along with resistive index (Ri, pulsative index (Pi, and CCW intima-media thickness (IMT, CCW rigidity index (iRIG was estimated using empirical equation. Non-invasive evaluation was performed in cardiac transplant recipients prior the endomyo- cardial biopsy. Results. Neither of Ri, Pi, or CCW IMT were different in studied subgroups. iRIG was signifi- cantly lower in SCAD pts when compared to the dilated cardiomyopathy subgroup. The later had similar values with cardiac transplant recipients without rejection. Antibody-mediated and cellular rejection were found in 22 (23.7% and 17 (18.3% cardiac recipients, respectively. Mean iRIG in pts without rejection was significantly lower in comparison to antibody-mediated rejection and cell-mediated (5514.7 ± 2404.0 vs 11856.1 ± 6643.5 and 16071.9 ± 10029.1 cm/sec2, respectively, p = 0.001. Area under ROC for iRIG was 0.90 ± 0.03 units2.

    Purpose: Recent evidence suggests that the heart may be injured by ionizing radiation at lower doses than was previously thought. This raises concerns about the cardiovascular risks from exposure to radiation during space travel. Since space travel is associated with exposure to both protons from solar particle events and heavy ions from galactic cosmic rays, we here examined the effects of a "priming" dose of protons on the cardiac cellular and molecular response to a "challenge" dose of 56Fe in a mouse model. Methods: Male C57BL/6 mice at 10 weeks of age were exposed to sham-irradiation, 0.1 Gy of protons (150 MeV), 0.5 Gy of 56Fe (600 MeV/n), or 0.1 Gy of protons 24 hours prior to 0.5 Gy of 56Fe. Hearts were obtained at 7 days post-irradiation and western-blots were used to determine protein markers of cardiac remodeling, inflammatory infiltration, and cell death. Results: Exposure to 56Fe caused an increase in expression of α-smooth muscle cell actin, collagen type III, the inflammatory cell markers mast cell tryptase, CD2 and CD68, the endothelial glycoprotein thrombomodulin, and cleaved caspase 3. Of all proteins investigated, protons at a dose of 0.1 Gy induced a small increase only in cleaved caspase 3 levels. On the other hand, exposure to protons 24 hours before 56Fe prevented all of the responses to 56Fe. Conclusions: This study shows that a low dose of protons may prime the heart to respond differently to a subsequent challenge dose of heavy ions. Further investigation is required to identify responses at additional time points, consequences for cardiac function, threshold dose levels, and mechanisms by which a proton priming dose may alter the response to heavy ions.

  5. Assessment of atherosclerotic plaque vulnerability of coronary arteries in cases of sudden cardiac death

    International Nuclear Information System (INIS)

    To study the plaque vulnerability in coronary arteries taken from autopsy specimens, of individuals dying of ischemic heart disease in our setup and to compare it with atheroma of those who died of non-cardiac causes. Sixty coronary arteries having atherosclerosis, from autopsies of patients who died of sudden cardiac death were divided into case and control groups. Case group included thirty coronary arteries having atherosclerosis from autopsies of patients of whose death was attributable to Ischemic Heart Disease (IHD). Control group included thirty coronary arteries where atherosclerotic changes were found by chance (death not attributable to ischemic heart disease). Plaques were assessed for fibrous cap thickness, foam cells; mean percentage of inflammatory cells on Haemotoxylin and Eosin (H and E) stained slides whereas immunohistochemical (IHC) markers for T-Cells were done by IHC stain method. In present study, foam cells are significantly more in study group than in control group (P=0.007). Fibrous cap thickness fulfilling the criteria of vulnerable plaque was more in study group as compared to control group (P<0.001). The present study demonstrated that there was insignificant difference (P=0.152), in the mean percentage of inflammatory cells in case group and control group. An overall significant association was found between vulnerable plaque and death due to ischemic heart disease (P<0.001). Conclusion: Patients dying of ischemic heart disease have more vulnerable plaque in their coronary arteries as compared to those dying from non ischemic cause. Although this is an autopsy study but the significance of in this study can be very important to guide cardiologists to identify patients at high risk of acute coronary syndrome and use new diagnostic modalities like intravascular ultrasonography and therapeutic strategies like genomic and proteomic techniques. This will help the early detection and treatment of such cases and may ultimately reduce the

    Systemic inflammatory response syndrome (SIRS) is triggered by various factors such as surgical operation, trauma, burn injury, ischemia, pancreatitis and bacterial translocation. Sepsis is a SIRS associated with bacterial infection. SIRS and sepsis tend to trigger excessive production of inflammatory cytokines and other inflammatory molecules and induce multiple organ failure, such as acute lung injury, acute kidney injury and inflammatory cardiac injury. Epithelial and endothelial cells in some major organs express inflammatory receptors on the plasma membrane and work as alert cells for inflammation, and regulation of these alert cells could have a relieving effect on the inflammatory response. In inflammatory conditions, initial cardiac dysfunction is mediated by decreased preload and adequate infusion therapy is required. Tachyarrhythmia is a complication of inflammatory conditions and early control of the inflammatory reaction would prevent the structural remodeling that is resistant to therapies. Furthermore, there seems to be crosstalk between major organs with a central focus on the kidneys in inflammatory conditions. As an alert cell strategy, volatile anesthetics, sevoflurane and isoflurane, seem to have anti-inflammatory effects, and both experimental and clinical studies have shown the beneficial effects of these drugs in various settings of inflammatory conditions. On the other hand, in terms of intravenous anesthetics, propofol and ketamine, their current status is still controversial as there is a lack of confirmatory evidence on whether they have an organ-protective effect in inflammatory conditions. The local anesthetic lidocaine suppressed inflammatory responses upon both systemic and local administration. For the control of inflammatory conditions, anesthetic agents may be a target of drug development in accordance with other treatments and drugs. PMID:25229471

    Although short-term outcomes have improved with modern era immunosuppression, little progress has been made in long-term graft survival in cardiac transplantation. Antibody-mediated rejection (AMR) is one of the leading causes of graft failure and contributes significantly to poor long-term outcomes. Endothelial cell (EC) injury, intravascular macrophage infiltrate and microvascular inflammation are the histological features of AMR. Nevertheless, mechanisms of AMR remain unclear and treatment is still limited. Here, we investigated the mechanisms underlying vascular and inflammatory cell network involved in AMR at endothelial and macrophage levels, using endomyocardial transplant biopsies and EC/monocyte cocultures. First, we found that AMR associates with changes in Notch signaling at endothelium/monocyte interface including loss of endothelial Notch4 and the acquisition of the Notch ligand Dll4 in both cell types. We showed that endothelial Dll4 induces macrophage polarization into a pro-inflammatory fate (CD40(high)CD64(high)CD200R(low) HLA-DR(low)CD11b(low)) eliciting the production of IL-6. Dll4 and IL-6 are both Notch-dependent and are required for macrophage polarization through selective down and upregulation of M2- and M1-type markers, respectively. Overall, these findings highlight the impact of the graft's endothelium on macrophage recruitment and differentiation upon AMR via Notch signaling. We identified Dll4 and IL-6 as coregulators of vascular inflammation in cardiac transplantation and as potential targets for immunotherapy. PMID:26826491

    N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) is related to stress-induced myocardial ischemia and/or volume overload, both common in patients with renal dysfunction. This might compromise the prognostic usefulness of NT-pro-BNP in patients with renal impairment before vascular surgery. We assessed the prognostic value of NT-pro-BNP in the entire strata of renal function. In 356 patients (median age 69 years, 77% men), cardiac history, glomerular filtration rate (GFR, ml/min/1.73 m(2)), and NT-pro-BNP level (pg/ml) were assessed preoperatively. Troponin T and electrocardiography were assessed postoperatively on days 1, 3, 7, and 30. The end point was the composite of cardiovascular death, Q-wave myocardial infarction, and troponin T release. Multivariate analysis was used to evaluate the interaction between GFR, NT-pro-BNP and their association with postoperative outcome. Median GFR was 78 ml/min/1.73 m(2) and the median concentration of NT-pro-BNP was 197 pg/ml. The end point was reached in 64 patients (18%); cardiac death occurred in 7 (2.0%), Q-wave myocardial infarction in 34 (9.6%), and non-Q-wave myocardial infarction in 23 (6.5%). After adjustment for confounders, NT-pro-BNP levels and GFR remained significantly associated with the end point (p = 0.005). The prognostic value of NT-pro-BNP was most pronounced in patients with GFR > or =90 (odds ratio [OR] 1.18, 95% confidence interval [CI] 0.80 to 1.76) compared with patients with GFR 60 to 89 (OR 1.04, 95% CI 1.002 to 1.07), and with GFR 30 to 59 (OR 1.12, 95% CI 1.03 to 1.21). In patients with GFR discriminative value of NT-pro-BNP is most pronounced in patients with GFR > or =90 ml/min/1.73 m(2) and has no prognostic value in patients with GFR <30 ml/min/1.73 m(2).

    The evidence regarding specific cardiac perception and discrimination, and its relationship to voluntary cardiac control, is critically reviewed. Studies are considered in three sections, depending on the method used to assess cardiac perception: questionnaire assessment, discrimination procedures, and heartbeat tracking. The heartbeat tracking procedure would appear to suffer least from interpretative difficulties. Recommendations are made regarding the style of analysis used to assess heartbeat perception in such tracking tasks. PMID:348240

    Full Text Available Abstract Rationale Several epidemiological studies associated exposure to increased levels of particulate matter in Augsburg, Germany with cardiovascular mortality and morbidity. To elucidate the mechanisms of cardiovascular impairments we investigated the cardiopulmonary responses in spontaneously hypertensive rats (SHR, a model for human cardiovascular diseases, following intratracheal instillation of dust samples from Augsburg. Methods 250 μg, 500 μg and 1000 μg of fine ambient particles (aerodynamic diameter 2.5-AB collected from an urban background site in Augsburg during September and October 2006 (PM2.5 18.2 μg/m3, 10,802 particles/cm3 were instilled in 12 months old SHRs to assess the inflammatory response in bronchoalveolar lavage fluid (BALF, blood, lung and heart tissues 1 and 3 days post instillation. Radio-telemetric analysis was performed to investigate the cardiovascular responses following instillation of particles at the highest dosage based on the inflammatory response observed. Results Exposure to 1000 μg of PM2.5-AB was associated with a delayed increase in delta mean blood pressure (ΔmBP during 2nd-4th day after instillation (10.0 ± 4.0 vs. -3.9 ± 2.6 mmHg and reduced heart rate (HR on the 3rd day post instillation (325.1 ± 8.8 vs. 348.9 ± 12.5 bpm. BALF cell differential and inflammatory markers (osteopontin, interleukin-6, C-reactive protein, and macrophage inflammatory protein-2 from pulmonary and systemic level were significantly induced, mostly in a dose-dependent way. Protein analysis of various markers indicate that PM2.5-AB instillation results in an activation of endothelin system (endothelin1, renin-angiotensin system (angiotensin converting enzyme and also coagulation system (tissue factor, plasminogen activator inhibitor-1 in pulmonary and cardiac tissues during the same time period when alternation in ΔmBP and HR have been detected.

    Full Text Available Abstract Background Azelnidipine (AZL, a long-acting dihydropyridine-based calcium antagonist, has been recently approved and used for treating ischemic heart disease and cardiac remodeling after myocardial infarction, however, its effect on hyperglycemia-induced cardiac damage has not been studied. Methods This study examined the effect of AZL on circulating markers of cardiac damage, altered lipid and cytokines profile and markers of oxidative stress including homocysteine in diabetic rats. Results STZ induced diabetes caused a significant increase in blood glucose levels. It also resulted in an increase in the levels of homocysteine and cardiac damage markers, like Troponin-1, CK-MB, CK-NAC, uric acid, LDH and alkaline phosphatase. Moreover, there was an increase in the levels of proinflammatory cytokines like TNF-α, IFN-γ, and TGF-β and decrease in the levels of IL-4 and IL-10. Additionally, there was increase in the levels of cholesterol, triglycerides, LDL, VLDL and a decrease in HDL in these animals. There was an altered antioxidant enzyme profile which resulted in a notable increase in the levels of oxidative stress markers like lipid peroxides, nitric oxide and carbonylated proteins. Compared with the untreated diabetic rats, AZL treatment significantly reduced the levels of troponin-1 (P Conclusion Our results indicate that AZL treatment can reduce the risk of hyperglycemia induced metabolic disorders and its role can be further extended to explore its therapeutic potential in diabetic patients with cardiac complications.

    Sepsis is known as the presence of a Systemic Inflammatory Response Syndrome (SIRS) in response to an infection. In the USA alone, 750,000 cases of severe sepsis are diagnosed annually. More than 70% of sepsis-related deaths occur due to organ failure and more than 50% of septic patients demonstrate cardiac dysfunction. Patients with sepsis who develop cardiac dysfunction have significantly higher mortality, and thus cardiac dysfunction serves as a predictor of survival in sepsis.

    A dynamic cardiac phantom can play a significant role in the evaluation and development of ultrasound and cardiac magnetic resonance (MR) motion tracking and registration methods. A four chamber multimodal cardiac phantom has been designed and built to simulate normal and pathologic hearts with different degrees of "infarction" and "scar tissues". In this set up, cardiac valves have been designed and modeled as well. The four-chamber structure can simulate the asymmetric ventricular, atrial and valve motions. Poly Vinyl Alcohol (PVA) is used as the principal material since it can simulate the shape, elasticity, and MR and ultrasound properties of the heart. The cardiac shape is simulated using a four-chamber mold made of polymer clay. An additional pathologic heart phantom containing stiff inclusions has been manufactured in order to simulate an infracted heart. The stiff inclusions are of different shapes and different degrees of elasticity and are able to simulate abnormal cardiac segments. The cardiac elasticity is adjusted based on freeze-thaw cycles of the PVA cryogel for normal and scarred regions. Ultrasound and MRI markers were inserted in the cardiac phantom as landmarks for validations. To the best of our knowledge, this is the first multimodal phantom that models a dynamic four-chamber human heart including the cardiac valve.

  5. The peripheral benzodiazepine receptor ligand PK11195 binds with high affinity to the acute phase reactant α1-acid glycoprotein: implications for the use of the ligand as a CNS inflammatory marker

    International Nuclear Information System (INIS)

    The peripheral benzodiazepine receptor ligand PK11195 has been used as an in vivo marker of neuroinflammation in positron emission tomography studies in man. One of the methodological issues surrounding the use of the ligand in these studies is the highly variable kinetic behavior of [11C]PK11195 in plasma. We therefore undertook a study to measure the binding of [3H]PK11195 to whole human blood and found a low level of binding to blood cells but extensive binding to plasma proteins. Binding assays using [3H]PK11195 and purified human plasma proteins demonstrated a strong binding to α1-acid glycoprotein (AGP) and a much weaker interaction with albumin. Immunodepletion of AGP from plasma resulted in the loss of plasma [3H]PK11195 binding demonstrating: (i) the specificity of the interaction and (ii) that AGP is the major plasma protein to which PK11195 binds with high affinity. PK11195 was able to displace fluorescein-dexamethasone from AGP with IC50 of 11C]PK11195 to the brain parenchyma in diseases with blood brain barrier breakdown. Finally, local synthesis of AGP at the site of brain injury may contribute the pattern of [11C]PK11195 binding observed in neuroinflammatory diseases

    International Nuclear Information System (INIS)

    Objective: To investigate the MRI features of cardiac myxoma by correlated with its pathological findings. Methods: MRI features of 22 cases of pathologically confirmed cardiac myxomas were retrospectively reviewed. Results: Of 22 cases, 21 are solitary, 12 located in left atrium, 6 located in right atrium, 2 located in left ventricle and 1 located in fight ventricle. The other one occupied multiple chambers. MRI: 19 are heterogeneous and 3 are homogeneous. Cine-MRI: 18 attach to the endocardium with a pedunculated stalk and 4 are sessile and with a broad attachment. Thirteen cases had secondary valve insufficience or stenosis. Nine have compromised cardiac function. Nineteen cases demonstrated mild to moderate heterogeneous enhancement after Gd-DTPA administration and 3 case showed no enhancement. Four cases had gadolinium first-pass perfusion study and showed a slow and continuous increasing time-intensity, lower than normal myocardium. The pedicles and wall showed delay enhancement. Pathologic findings: 21 are oval and lobular configuration, 1 is grape-like. Ten cases had fresh hemorrhage and 5 had chronic hemorrhage. Fourteen had necrosis, 2 had cystic change and 4 had calcification. Blood vessels or inflammatory cells could be detected in 19 cases. Conclusions: MRI can evaluate the size, location, morphology, especially the vascularity, histologic features and cardiac function of cardiac myxomas. (authors)

  10. Cardiac tumours in children

    2007-03-01

    Full Text Available Abstract Cardiac tumours are benign or malignant neoplasms arising primarily in the inner lining, muscle layer, or the surrounding pericardium of the heart. They can be primary or metastatic. Primary cardiac tumours are rare in paediatric practice with a prevalence of 0.0017 to 0.28 in autopsy series. In contrast, the incidence of cardiac tumours during foetal life has been reported to be approximately 0.14%. The vast majority of primary cardiac tumours in children are benign, whilst approximately 10% are malignant. Secondary malignant tumours are 10–20 times more prevalent than primary malignant tumours. Rhabdomyoma is the most common cardiac tumour during foetal life and childhood. It accounts for more than 60% of all primary cardiac tumours. The frequency and type of cardiac tumours in adults differ from those in children with 75% being benign and 25% being malignant. Myxomas are the most common primary tumours in adults constituting 40% of benign tumours. Sarcomas make up 75% of malignant cardiac masses. Echocardiography, Computing Tomography (CT and Magnetic Resonance Imaging (MRI of the heart are the main non-invasive diagnostic tools. Cardiac catheterisation is seldom necessary. Tumour biopsy with histological assessment remains the gold standard for confirmation of the diagnosis. Surgical resection of primary cardiac tumours should be considered to relieve symptoms and mechanical obstruction to blood flow. The outcome of surgical resection in symptomatic, non-myxomatous benign cardiac tumours is favourable. Patients with primary cardiac malignancies may benefit from palliative surgery but this approach should not be recommended for patients with metastatic cardiac tumours. Surgery, chemotherapy and radiotherapy may prolong survival. The prognosis for malignant primary cardiac tumours is generally extremely poor.

  11. A novel redox-active metalloporphyrin reduces reactive oxygen species and inflammatory markers but does not improve marginal mass engraftment in a murine donation after circulatory death islet transplantation model.

    Islet transplantation is a highly effective treatment for stabilizing glycemic control for select patients with type-1 diabetes. Despite improvements to clinical transplantation, single-donor transplant success has been hard to achieve routinely, necessitating increasing demands on viable organ availability. Donation after circulatory death (DCD) may be an alternative option to increase organ availability however, these organs tend to be more compromised. The use of metalloporphyrin anti-inflammatory and antioxidant (MnP) compounds previously demonstrated improved in vivo islet function in preclinical islet transplantation. However, the administration of MnP (BMX-001) in a DCD islet isolation and transplantation model has yet to be established. In this study, murine donors were subjected to a 15-min warm ischemic (WI) period prior to isolation and culture with or without MnP. Subsequent to one-hour culture, islets were assessed for in vitro viability and in vivo function. A 15-minute WI period significantly reduced islet yield, regardless of MnP-treatment relative to yields from standard isolation. MnP-treated islets did not improve islet viability compared to DCD islets alone. MnP-treatment did significantly reduce the presence of extracellular reactive oxygen species (ROS) (p < 0 .05). Marginal, syngeneic islets (200 islets) transplanted under the renal capsule exhibited similar in vivo outcomes regardless of WI or MnP-treatment. DCD islet grafts harvested 7 d post-transplant exhibited sustained TNF-α and IL-10, while MnP-treated islet-bearing grafts demonstrated reduced IL-10 levels. Taken together, 15-minute WI in murine islet isolation significantly impairs islet yield. DCD islets do indeed demonstrate in vivo function, though MnP therapy was unable to improve viability and engraftment outcomes. PMID:27220256

    Cardiac miRNAs (miR-1, miR133a, miR-208a/b, and miR-499) are abundantly expressed in the myocardium. They play a central role in cardiogenesis, heart function and pathology. While miR-1 and miR-133a predominantly control early stages of cardiogenesis supporting commitment of cardiac-specific muscle lineage from embryonic stem cells and mesodermal precursors, miR-208 and miR-499 are involved in the late cardiogenic stages mediating differentiation of cardioblasts to cardiomyocytes and fast/slow muscle fiber specification. In the heart, miR-1/133a control cardiac conductance and automaticity by regulating all phases of the cardiac action potential. miR-208/499 located in introns of the heavy chain myosin genes regulate expression of sarcomeric contractile proteins. In cardiac pathology including myocardial infarction (MI), expression of cardiac miRNAs is markedly altered that leads to deleterious effects associated with heart wounding, arrhythmia, increased apoptosis, fibrosis, hypertrophy, and tissue remodeling. In acute MI, circulating levels of cardiac miRNAs are significantly elevated making them to be a promising diagnostic marker for early diagnosis of acute MI. Great cardiospecific capacity of these miRNAs is very helpful for enhancing regenerative properties and survival of stem cell and cardiac progenitor transplants and for reprogramming of mature non-cardiac cells to cardiomyocytes.

  13. Endothelial Dysfunction in Chronic Inflammatory Diseases

    Directory of Open Access Journals (Sweden)

    Curtis M. Steyers

    2014-06-01

    Full Text Available Chronic inflammatory diseases are associated with accelerated atherosclerosis and increased risk of cardiovascular diseases (CVD. As the pathogenesis of atherosclerosis is increasingly recognized as an inflammatory process, similarities between atherosclerosis and systemic inflammatory diseases such as rheumatoid arthritis, inflammatory bowel diseases, lupus, psoriasis, spondyloarthritis and others have become a topic of interest. Endothelial dysfunction represents a key step in the initiation and maintenance of atherosclerosis and may serve as a marker for future risk of cardiovascular events. Patients with chronic inflammatory diseases manifest endothelial dysfunction, often early in the course of the disease. Therefore, mechanisms linking systemic inflammatory diseases and atherosclerosis may be best understood at the level of the endothelium. Multiple factors, including circulating inflammatory cytokines, TNF-α (tumor necrosis factor-α, reactive oxygen species, oxidized LDL (low density lipoprotein, autoantibodies and traditional risk factors directly and indirectly activate endothelial cells, leading to impaired vascular relaxation, increased leukocyte adhesion, increased endothelial permeability and generation of a pro-thrombotic state. Pharmacologic agents directed against TNF-α-mediated inflammation may decrease the risk of endothelial dysfunction and cardiovascular disease in these patients. Understanding the precise mechanisms driving endothelial dysfunction in patients with systemic inflammatory diseases may help elucidate the pathogenesis of atherosclerosis in the general population.

    Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease characterized by extensive synovitis resulting in erosions of articular cartilage and marginal bone with joint destruction. The lack of immunological tolerance in RA represents the first step toward the development of autoimmunity. Susceptible individuals, under the influence of environmental factors, such as tobacco smoke, and silica exposure, develop autoimmune phenomena that result in the presence of autoantibodies. HLA and non-HLA haplotypes play a major role in determining the development of specific autoantibodies differentiating anti-citrullinated antibodies (ACPA)-positive and negative RA patients. Rheumatoid factor (RF) and ACPA are the serological markers for RA, and during the preclinical immunological phase, autoantibody titers increase with a progressive spread of ACPA antigens repertoire. The presence of ACPA represents an independent risk factor for developing RA in patients with undifferentiated arthritis or arthralgia. Moreover, anti-CarP antibodies have been identified in patients with RA as well as in individuals before the onset of clinical symptoms of RA. Several autoantibodies mainly targeting post-translational modified proteins have been investigated as possible biomarkers to improve the early diagnosis, prognosis and response to therapy in RA patients. Psoriatic arthritis (PsA) is distinguished from RA by infrequent positivity for RF and ACPA, together with other distinctive clinical features. Actually, specific autoantibodies have not been described. Recently, anti-CarP antibodies have been reported in sera from PsA patients with active disease. Further investigations on autoantibodies showing high specificity and sensibility as well as relevant correlation with disease severity, progression, and response to therapy are awaited in inflammatory arthritides.

  15. Stimulating endogenous cardiac regeneration

    Directory of Open Access Journals (Sweden)

    Amanda eFinan

    2015-09-01

    Full Text Available The healthy adult heart has a low turnover of cardiac myocytes. The renewal capacity, however, is augmented after cardiac injury. Participants in cardiac regeneration include cardiac myocytes themselves, cardiac progenitor cells, and peripheral stem cells, particularly from the bone marrow compartment. Cardiac progenitor cells and bone marrow stem cells are augmented after cardiac injury, migrate to the myocardium, and support regeneration. Depletion studies of these populations have demonstrated their necessary role in cardiac repair. However, the potential of these cells to completely regenerate the heart is limited. Efforts are now being focused on ways to augment these natural pathways to improve cardiac healing, primarily after ischemic injury but in other cardiac pathologies as well. Cell and gene therapy or pharmacological interventions are proposed mechanisms. Cell therapy has demonstrated modest results and has passed into clinical trials. However, the beneficial effects of cell therapy have primarily been their ability to produce paracrine effects on the cardiac tissue and recruit endogenous stem cell populations as opposed to direct cardiac regeneration. Gene therapy efforts have focused on prolonging or reactivating natural signaling pathways. Positive results have been demonstrated to activate the endogenous stem cell populations and are currently being tested in clinical trials. A potential new avenue may be to refine pharmacological treatments that are currently in place in the clinic. Evidence is mounting that drugs such as statins or beta blockers may alter endogenous stem cell activity. Understanding the effects of these drugs on stem cell repair while keeping in mind their primary function may strike a balance in myocardial healing. To maximize endogenous cardiac regeneration,a combination of these approaches couldameliorate the overall repair process to incorporate the participation ofmultiple cell players.

    A high consumption of trans fatty acids (TFAs) is associated with an increased risk of cardiovascular diseases (CVDs). High-density lipoproteins (HDLs) have many cardioprotective properties and transport functional microRNAs (miRNAs) to recipient cells. We hypothesized that dietary TFAs modify the HDL-carried miRNA profile, therefore modulating its cardioprotective properties. We assessed whether consumption of dietary TFAs modifies HDL-carried miR-223-3p and miR-135a-3p concentration and the inter-relationship between diet-induced changes in HDL-carried miRNA concentration and CVD risk markers. In a double blind, randomized, crossover, controlled study, 9 men were fed each of 3 experimental isoenergetic diets: 1) High in industrial TFA (iTFA; 3.7% energy); 2) High in TFA from ruminants (rTFA; 3.7% energy); 3) Low in TFA (control; 0.8% energy) for 4 weeks each. HDLs were isolated by ultracentrifugation and miRNAs were quantified by RT-qPCR. Variations in HDL-miR-223-3p concentration were negatively correlated with variations in HDL-cholesterol after the iTFA diet (rs = 0.82; P = 0.007), and positively correlated with variations in C-reactive protein concentration after the rTFA diet (rs = 0.75; P = 0.020). Variations in HDL-miR-135a-3p concentration were positively correlated with variations in total triglyceride (TG) concentration following the iTFA diet (rs = -0.82; P = 0.007), and with variations in low-density lipoprotein (LDL)-TG concentration following the rTFA diet (rs = 0.83; P = 0.005), compared to the control diet. However, the consumption of dietary TFAs has no significant unidirectional impact on HDL-carried miR-223-3p and miR-135a-3p concentrations. Our results suggest that the variability in the HDL-carried miRNAs response to TFA intake, by being associated with variations in CVD risk factors, might reflect physiological changes in HDL functions.

    This study was a detailed microscopic analysis of the changes of vaginal microflora characteristics after application of 0.03 mg estriol-lactobacilli combination on the vaginal ecosystem in postmenopausal breast cancer (BC) survivors on aromatase inhibitors (AI) with severe atrophic vaginitis. A total of 16 BC women on AI applied daily one vaginal tablet of Gynoflor® for 28 days followed by a maintenance therapy of three tablets weekly for 8 weeks. During four follow up visits a smear from the upper lateral vaginal wall was analysed by phase contrast microscopy at 400 times magnification in order to classify the lactobacillary grades(LBG), bacterial vaginosis (BV), aerobic vaginitis (AV), vulvovaginal candidosis (VVC), proportional number of leukocytes and evidence of parabasal cells and epitheliolysis. LBG improved from 81% LBG-III at entry to 88% LBG-I&IIa after 2 weeks of initial therapy, which further improved upon follow up (p treatment (p < 0.01). While at entry most patients had moderate or severe AV, after maintenance therapy no patient except one had AV. The number of leukocytes dropped dramatically from a score of 1.78 ± 0.70 to 1.06 ± 0.25 which was consistent till the end of the study (p < 0.01). Parabasal cells dropped from a score of 3.4 ± 0.64 at entry to 1.3 ± 0.60 at the final visit (p trend < 0.01). Starting from a low rate of Candida colonisation of 2/14 (14%), a sudden rise to 7/16 (44%) occurred after 2 weeks, to return back to base levels at subsequent visits. The vaginal use of ultra-low dose estriol and lactobacilli results in rapid and enduring improvement of all markers of the vaginal microflora and epithelial vaginal cell quality in women with breast cancer on AI with dyspareunia. Candida may develop soon after its use, but rapidly disappears again upon their prolonged use. Due to its excellent safety profiles and clinical efficacy we recommend this product as first choice in women on AI with severe dyspareunia. PMID:26223323

    High methionine diet (HMD) for example red meat which includes lamb, beef, pork can pose cardiac threat and vascular dysfunction but the mechanisms are unclear. We hypothesize that a diet rich in methionine can malfunction the cardiovascular system in three ways: (1) by augmenting oxidative stress; (2) by inflammatory manifestations; and (3) by matrix/vascular remodeling. To test this hypothesis we used four groups of mice: (1) WT; (2) WT + methionine; (3) CBS(+/-) ; (4) CBS(+/-) +methionine. We observed high oxidative stress in mice fed with methionine which was even higher in CBS(+/-) and CBS(+/-) +methionine. Higher oxidative stress was indicated by high levels of SOD-1 in methionine fed mouse hearts whereas IL-1β, IL-6, TNFα, and TLR4 showed high inflammatory manifestations. The upregulated levels of eNOS/iNOS and upregulated levels of MMP2/MMP9 along with high collagen deposition indicated vascular and matrix remodeling in methionine fed mouse. We evaluated the cardiac function which was dysregulated in the mice fed with HMD. These mice had decreased ejection fraction and left ventricular dysfunction which subsequently leads to adverse cardiac remodeling. In conclusion, our study clearly shows that HMD poses a cardiac threat by increasing oxidative stress, inflammatory manifestations, matrix/vascular remodeling, and decreased cardiac function. J.

    To determine the events leading to cardiac fibrosis in aldosterone-salt hypertensive rats, we studied protein and mRNA accumulation of procollagens I and III for 60 days. After 3 and 7 days of treatment systolic pressure was normal, and no histological or biochemical changes were seen in rat hearts. At day 15 arterial pressure was raised (+40%) and left ventricular hypertrophy was +15%. Cardiac examination after hemalun-eosin staining and immunolabeling with anticollagen I and III antibodies showed no structural alterations, but an 83% increase in right ventricular type III procollagen mRNA levels was found. At 30 and 60 days we found progressive cardiac fibrosis, with inflammatory cells, myocyte necrosis, and elevation of both types I and III procollagen mRNA levels in both ventricles. To determine whether aldosterone had effects on Na,K-ATPase that might lead to ionic disturbances and induce myocyte necrosis, we studied the major cardiac Na,K-ATPase isoform genes. Although Na,K-ATPase alpha 1- and beta 1-subunit mRNA levels were elevated in kidney at day 1, neither of these cardiac transcripts nor the specific alpha 2 isoform was altered between 1 and 15 days. These results show that accumulation of procollagen mRNAs occurs before collagen deposition. Cardiac alterations are late and not preceded by changes in Na,K-ATPase cardiac gene expression, precluding a direct modulation of cardiac collagen synthesis and Na,K-ATPase by aldosterone.

    Background Previous studies showed that overexpression of sarco-endoplasmic reticulum calcium ATPase (SERCA2a) in a variety of heart failure (HF) models was associated with greatly enhanced cardiac performance. However, it still undefined the effect of SERCA2a overexpression on the systemic inflammatory response and neuro-hormonal factors. Methods A rapid right ventricular pacing model of experimental HF was used in beagles. Then the animals underwent recombinant adeno-associated virus 1 (rAAV1) mediated gene transfection by direct intra-myocardium injection. HF animals were randomized to receive the SERCA2a gene, enhanced green fluorescent protein (control) gene, or equivalent phosphate buffered saline. Thirty days after gene delivery, the cardiac function was evaluated by echocardiographic testing. The protein level of SERCA2a was measured by western blotting. The proteomic analysis of left ventricular (LV) sample was determined using two-dimensional (2-D) gel electrophoresis and MALDI-TOF-MS. The serum levels of the systemic inflammatory and neuro-hormonal factors were assayed using radioimmunoassay kits. Results The cardiac function improved after SERCA- 2a gene transfer due to the significantly increased SERCA2a protein level. Beagles treated with SERCA2a had significantly decreased serum levels of the inflammatory markers (interleukin-6 and tumor necrosis factor-α) and neuro-hormonal factors (brain natriuretic peptide, endothelin-1 and angiotensin Ⅱ) compared with HF animals. The myocardial proteomic analysis showed that haptoglobin heavy chain, heat shock protein (alpha-crystallin-related, B6) were down-regulated, and galectin-1 was up-regulated in SERCA2a group compared with HF group, companied by up-regulated contractile proteins and NADH dehydrogenase. Conclusions These findings demonstrate that regional intramyocardial injections of rAAV1-SERCA2a vectors may improve global LV function, correlating with reverse activation of the systemic inflammatory

    Full Text Available Introduction: Cardioplegic cardiac arrest with subsequent ischemic-reperfusion injuries can lead to the development of inflammation of the myocardium, leucocyte activation, and release of cardiac enzymes. Flow reduction to the bronchial arteries, causing low-flow lung ischemia, leads to the development of a pulmonary regional inflammatory response. Hypoventilation during cardiopulmonary bypass (CPB is responsible for development of microatelectasis, hydrostatic pulmonary edema, poor compliance, and a higher incidence of infection. Based on these facts, prevention methods of these complications were developed. The aim of this study was to evaluate constant coronary perfusion (CCP and the “beating heart” in combination with pulmonary artery perfusion (PAP and “ventilated lungs” technique for heart and lung protection in cardiac surgery with CPB.Methods. After ethical approval and written informed consent, 80 patients undergoing cardiac surgery with normothermic CPB were randomized in three groups. In the first group (22 patients, the crystalloid cardioplegia without lung ventilation/perfusion techniques were used. In the second group (30 patients, the CCP and “beating heart” without lung ventilation/perfusion techniques were used. In the third group (28 patients, the CCP with PAP and lung ventilation techniques were used. Clinical, functional parameters, myocardial damage markers (CK MB level, oxygenation index, and lung compliance were investigated.Results. There were higher rates of spontaneous cardiac recovery and lower doses of inotrops in the second and third groups. Myocardial contractility function was better preserved in the second and third groups. The post-operative levels of CK-MB were lower than in control group.  Three hours after surgery CK-MB levels in the second and third  groups were lower by 38.1% and 33.3%, respectively. Eight hours after surgery, CK-MB levels were lower in the second and third groups by 45.9% and

    Full Text Available Objective: to assess the rate of silent myocardial ischemia (SMI and the pattern of cardiac rhythm disturbances in women with rheumatoidarthritis (RA, their association with traditional risk factors (TRF for cardiovascular diseases (CVD, with subclinical structural and functionalchanges in the heart and vessels, with the activity and severity of rheumatoid inflammation.Subjects and methods. Two hundred and ninety-one female patients aged less than 60 years with a valid diagnosis of RA and no clinicalsigns were examined. A control group consisted of 125 women without rheumatic diseases. In addition to the clinical manifestations, activity,and severity of RA, the authors assessed major TRFs for CVD, performed Holter ECG monitoring, common carotid artery duplex scanning, transthoracic echocardiographic study, and determined the levels of serum inflammatory markers.Results. The women with RA differ from the control group in the higher incidence of SMI, supraventricular arrhythmias (SVA and highgradepremature ventricular contractions (PVC. The patients with RA and SMI are characterized in terms of age-adjustment by higher disease activity (DAS28, systemic manifestations, cumulative larger-dose glucocorticoids (GC and a higher percentage of patients receiving disease-modifying anti-rheumatic drugs as compared with those with RA and no SMI with adjustment for age. High disease activity(DAS28, level of inflammatory markers, IgM rheumatoid arthritis seropositivity, and GC therapy are SVA-associated factors in women with RA; larger left ventricular end-diastolic dimension and serositis are factors associated with high-grade PVC.Conclusion. The RA women without clinical manifestations of CVD are recorded to have high rates of SMI, SVA, and high-grade PVC, which is primarily due to the activity and severity of rheumatoid inflammation.

    Full Text Available Background/Aims: Diabetes and Alzheimer's disease are often associated with each other, whereas the relationship between two diseases is ill-defined. Although hyperglycemia during diabetes is a major cause of encephalopathy, diabetes may also cause chronic inflammatory complications including peripheral neuropathy. Hence the role and the characteristics of inflammatory macrophages in the development of diabetic encephalopathy need to be clarified. Methods: Diabetes were induced in mice by i.p. injection of streptozotocin (STZ. Two weeks after STZ injection and confirmation of development of diabetes, inflammatory macrophages were eliminated by i.p. injection of 20µg saporin-conjugated antibody against a macrophage surface marker CD11b (saporin-CD11b twice per week, while a STZ-treated group received injection of rat IgG of same frequency as a control. The effects of macrophage depletion on brain degradation markers, brain malondialdehyde (MDA, catalase, superoxidase anion-positive cells and nitric oxide (NO were measured. Results: Saporin-CD11b significantly reduced inflammatory macrophages in brain, without affecting mouse blood glucose, serum insulin, glucose responses and beta cell mass. However, reduced brain macrophages significantly inhibited the STZ-induced decreases in brain MDA, catalase and superoxidase anion-positive cells, and the STZ-induced decreases in brain NO. Conclusion: Inflammatory macrophages may promote development of diabetic encephalopathy.

    2002-01-01

    Full Text Available BACKGROUND: Intra-coronary stents have been extensively employed in percutaneous coronary revascularization. However, despite breakthroughs and developments associated to this new technology, novel complications and findings have emerged compelling the cardiac surgeon to cope with this new scenario. The presence of an intra-coronary foreign body (stent might induce an inflammatory reaction carrying functional and structural repercussions of the coronary artery and surrounding cardiac muscle. METHOD:Patients, who had previously undergone stent implantation (6 to 18 months and were submitted to coronary artery bypass surgery, had biopsies taken from the grafted coronary artery distal to the stent and from the adjacent muscle. The collected samples were processed and stained with hematoxylin-eosin and histologically studied. RESULTS:The histology of the coronary artery distal to the stent revealed chronic inflammatory processes and an intimal acute inflammatory infiltrate, with polymorphonuclear leukocytes even at long term follow-up, 12 months after stent implantation, disclosing an ongoing inflammatory process. The myocardium adjacent to the stent implantation site exhibited a significant chronic inflammatory infiltrate and fibrosis compatible with myocarditis. CONCLUSION:The presence of an intra-coronary stent induces an acute and chronic inflammatory reaction, even over the long term, with involvement of the distal coronary artery and surrounding myocardium. Further studies are necessary to assess the inflammatory process extension and its consequences.

    Blunt injury to the heart ranges from contusion to disruption. This report comprises 14 patients seen during a 6-year period with cardiac rupture secondary to blunt trauma. Eight patients were injured in automobile accidents, two patients were injured in auto-pedestrian accidents, two were kicked in the chest by ungulates, and two sustained falls. Cardiac tamponade was suspected in ten patients. Five patients presented with prehospital cardiac arrest or arrested shortly after arrival. All underwent emergency department thoracotomy without survival. Two patients expired in the operating room during attempted cardiac repair; both had significant extracardiac injury. Seven patients survived, three had right atrial injuries, three had right ventricular injuries, and one had a left atrial injury. Cardiopulmonary bypass was not required for repair of the surviving patients. There were no significant complications from the cardiac repair. The history of significant force dispersed over a relatively small area of the precordium as in a kicking injury from an animal or steering wheel impact should alert the physician to possible cardiac rupture. Cardiac rupture should be considered in patients who present with signs of cardiac tamponade or persistent thoracic bleeding after blunt trauma. PMID:6708151

    Before non-cardiac surgery, evaluation of cardiac function is no frequent part of surgical treatment. European societies of anesthesiology and cardiology published consensus-guidelines in 2014 to present a reasonable approach for preoperative evaluation. This paper intends to differentiate the composite of perioperative risk and to display the guidelines methodical approach to handle it. Features to identify patients at risk from an ageing population with comorbidities, are the classification of surgical risk, functional capacity and risk indices. Application of diagnostic means, should be used adjusted to this risk estimation. Cardiac biomarkers are useful to discover risk of complications or mortality, that cannot be assessed by clinical signs. After preoperative optimization and perioperative cardiac protection, the observation of the postoperative period remains, to prohibit complications or even death. In consideration of limited resources of intensive care department, postoperative ward rounds beyond intensive care units are considered to be an appropriate instrument to avoid or recognize complications early to reduce postoperative mortality.

    Full Text Available Worldwide, cardiac surgery is a common procedure requiring a large quantity of allogeneic blood products, which are associated with postoperative complications. Leukocytes present in blood products may play a role in these complications, which are referred to as transfusion-related immunomodulation (TRIM. Several randomized controlled trials (RCTs in different settings investigated the effects of allogeneic leukocytes in red blood cells (RBCs. Cardiac surgery studies reported a reduction in postoperative infections and mortality in patients that received leukocyte-reduced RBCs compared with leukocyte-containing RBCs; this was mainly due to more deaths due to infections and multiple organ dysfunction syndrome (MODS in the group that received leukocyte-containing RBCs. Patients with postoperative complications had higher concentrations of inflammatory mediators. These findings suggest that leukocyte-containing transfusion during cardiac surgery induces a second insult to the systemic inflammatory response. In the present review we discuss the possible role of blood transfusions in cardiac surgery. Especially, we focus on the possible role of allogeneic leukocytes associated with postoperative complications after cardiac surgery.

    The goals of cardiac rehabilitation are (re-)conditioning and secondary prevention in patients with heart disease or an elevated cardiovascular risk profile. Rehabilitation is based on motivation through education, on adapted physical activity, instruction of relaxation techniques, psychological support and optimized medication. It is performed preferably in groups either in outpatient or inpatient settings. The Swiss working group on cardiac rehabilitation provides a network of institutions with regular quality auditing. Positive effects of rehabilitation programs on mortality and morbidity have been established by numerous studies. Although a majority of patients after cardiac surgery are being referred to rehabilitation, these services are notoriously underused after catheter procedures. PMID:26602848

    Full Text Available Transverse aortic constriction provokes a pro-inflammatory reaction and results in cardiac hypertrophy. Endogenous ligands contribute to cardiac hypertrophy via toll-like receptor (TLR-4 binding. A lack of TLR4 signaling diminishes hypertrophy and inflammation. Wild type mice undergoing aortic constriction respond to a lipopolysaccharide second-hit stimulus with hyperinflammation. The objective of this study was to assess whether other second-hit challenges utilizing TLR ligands provoke a comparable inflammatory reaction, and to find out whether this response is absent in TLR4 deficient mice. Assuming that cardiac stress alters the expression of pattern recognition receptors we analyzed the effects of transverse aortic constriction and second-hit virulence factor treatment on TLR expression, as well as cytokine regulation. Wild type and Tlr4-/- mice were subjected to three days of TAC and subsequently confronted with gram-positive TLR2 ligand lipoteichoic acid (LTA, 15 mg/g bodyweight or synthetic CpG-oligodesoxynucleotide 1668 thioate (20 nmol/kg bodyweight, 30 min after D-galactosamin desensitization signaling via TLR9. Hemodynamic measurements and organ preservation were performed 6 h after stimulation. Indeed, the study revealed a robust enhancement of LTA induced pattern recognition receptor and cytokine mRNA expression and a LTA-dependent reduction of hemodynamic pressure in TAC wild type mice. Second-Hit treatment with CpG-ODNs led to similar results. However, second-hit effects were abolished in Tlr4-/- mice. In total, these data indicate for the first time that cardiac stress increases the inflammatory response towards both, gram-negative and gram-positive, TLR ligands as well as bacterial DNA. The decrease of the inflammatory response upon TLR2 and -9 ligand challenge in TAC Tlr4-/- mice demonstrates that a lack of TLR4 signaling does not only prevent left ventricular hypertrophy but also protects the mice from a cardiac stress induced

    Biomarkers in acute cardiac care are gaining increasing interest given their clinical benefits. This study is a review of the major conditions in acute cardiac care, with a focus on biomarkers for diagnostic and prognostic assessment. Through a PubMed search, 110 relevant articles were selected. The most commonly used cardiac biomarkers (cardiac troponin, natriuretic peptides, and C-reactive protein) are presented first, followed by a description of variable acute cardiac conditions with their relevant biomarkers. In addition to the conventional use of natriuretic peptides, cardiac troponin, and C-reactive protein, other biomarkers are outlined in variable critical conditions that may be related to acute cardiac illness. These include ST2 and chromogranin A in acute dyspnea and acute heart failure, matrix metalloproteinase in acute chest pain, heart-type fatty acid binding protein in acute coronary syndrome, CD40 ligand and interleukin-6 in acute myocardial infarction, blood ammonia and lactate in cardiac arrest, as well as tumor necrosis factor-alpha in atrial fibrillation. Endothelial dysfunction, oxidative stress and inflammation are involved in the physiopathology of most cardiac diseases, whether acute or chronic. In summary, natriuretic peptides, cardiac troponin, C-reactive protein are currently the most relevant biomarkers in acute cardiac care. Point-of-care testing and multi-markers use are essential for prompt diagnostic approach and tailored strategic management. PMID:24046510

    Full Text Available Cardiac tumors are rare, and of these, primary cardiac tumors are even rarer. Metastatic cardiac tumors are about 100 times more common than the primary tumors. About 90% of primary cardiac tumors are benign, and of these the most common are cardiac myxomas. Approximately 12% of primary cardiac tumors are completely asymptomatic while others present with one or more signs and symptoms of the classical triad of hemodynamic changes due to intracardiac obstruction, embolism and nonspecific constitutional symptoms. Echocardiography is highly sensitive and specific in detecting cardiac tumors. Other helpful investigations are chest X-rays, magnetic resonance imaging and computerized tomography scan. Surgical excision is the treatment of choice for primary cardiac tumors and is usually associated with a good prognosis. This review article will focus on the general features of benign cardiac tumors with an emphasis on cardiac myxomas and their molecular basis.

    Full Text Available Inflammatory myofibroblastic tumor is an uncommon lesion of unknown cause. It encompasses a spectrum of myofibroblastic proliferation along with varying amount of inflammatory infiltrate. A number of terms have been applied to the lesion, namely, inflammatory pseudotumor, fibrous xanthoma, plasma cell granuloma, pseudosarcoma, lymphoid hamartoma, myxoid hamartoma, inflammatory myofibrohistiocytic proliferation, benign myofibroblatoma, and most recently, inflammatory myofibroblastic tumor. The diverse nomenclature is mostly descriptive and reflects the uncertainty regarding true biologic nature of these lesions. Recently, the concept of this lesion being reactive has been challenged based on the clinical demonstration of recurrences and metastasis and cytogenetic evidence of acquired clonal chromosomal abnormalities. We hereby report a case of inflammatory pseudotumor and review its inflammatory versus neoplastic behavior.

An athlete's death draws high public attention given that athletes are considered the healthiest category of society. The vast majority of sudden cardiac death in young athletes is due to congenital cardiac malformations such as hypertrophie cardiomyopathy and various coronary artery anomalies. In athletes over age 35, the usual cause of sudden cardiac death is coronary artery disease. With each tragic death of a young athlete, there is a question why this tragedy has not been prevented. The American College of Sports Medicine and the American Heart Association recommend that a pre-participation exam should include a complete cardiovascular history and physical examination.

    Aims Extracellular superoxide dismutase (EC-SOD) is an antioxidant that protects the heart from ischemia and the lung from inflammation and fibrosis. The role of cardiac EC-SOD under normal conditions and injury remains unclear. Cardiac toxicity, a common side effect of doxorubicin, involves oxidative stress. We hypothesize that EC-SOD is critical for normal cardiac function and protects the heart from oxidant-induced fibrosis and loss of function. Methods C57BL/6 and EC-SOD-null mice were treated with doxorubicin, 15 mg/kg (i.p.). After 15 days, echocardiography was used to assess cardiac function. Left ventricle (LV) tissue was used to assess fibrosis and inflammation by staining, western blot, and hydroxyproline analysis. Results At baseline EC-SOD-null mice have LV wall thinning and increases in LV end diastolic dimensions compared to wild type mice, but have normal cardiac function. After doxorubicin, EC-SOD-null mice have decreases in fractional shortening not apparent in WT mice. Lack of EC-SOD also leads to increases in myocardial apoptosis and significantly more LV fibrosis and inflammatory cell infiltration. Administration of the metalloporphyrin AEOL 10150 abrogates the loss of cardiac function, and potentially fibrosis, associated with doxorubicin treatment in both wild type and EC-SOD KO mice. Conclusions EC-SOD is critical for normal cardiac morphology and protects the heart from oxidant-induced fibrosis, apoptosis and loss of function. The antioxidant metalloporphyrin, AEOL 10150 effectively protects cardiac function from doxorubicin-induced oxidative stress, in vivo. These findings identify targets for the use of antioxidant agents in oxidant-induced cardiac fibrosis. PMID:19695260

    Sarcoidosis is a multi-system inflammatory disorder of unknown etiology resulting in formation of non-caseating granulomas. Cardiac involvement—which is associated with worse prognosis—has been detected in approximately 25% of individuals based on autopsy or cardiac imaging studies. Nevertheless, the diagnosis of cardiac sarcoidosis is challenging due to the low yield of endomyocardial biopsy, and the limited accuracy of various clinical criteria. Thus, no gold standard diagnostic criterion exists. This review will summarize the pathophysiology, diagnosis, and treatment of cardiac sarcoidosis with a focus on advanced cardiovascular imaging, We review the evidence to support a role for cardiac magnetic resonance (CMR) imaging in the initial evaluation of selected patients with suspected cardiac sarcoidosis, with cardiac positron emission tomography (PET) as an alternative or complementary initial diagnostic test in a subgroup of patients in whom CMR may be contra-indicated or when CMR is negative with continued clinical concern for myocardial inflammation. In addition to the diagnostic value of these tests, CMR and PET are also useful in identifying patients who have higher risk of adverse events such as ventricular tachycardia or death, in whom preventive therapies such as defibrillators should be more strongly considered. Although no randomized controlled trials for treatment of cardiac sarcoidosis exist, immunosuppressive therapy is often used. We review emerging evidence regarding the use of cardiac PET to identify and quantity the amount of myocardial inflammation as well as to guide the use of immunotherapy. Future studies are needed to determine the benefit of imaging guided therapies aimed at improving patient outcomes. PMID:26885492

    Objective:To investigate application of cardiopulmonary resuscitation(CPR) measures within the golden minutes inEurope.Methods:The material was taken from theUniversityClinical Center ofKosovo -EmergencyCentre inPristina, during the two(2) year period(2010-2011).The collected date belong to the patients with cardiac arrest have been recorded in the patients' log book protocol at the emergency clinic.Results:During the2010 to2011 in the emergency center of theCUCK inPristina have been treated a total of269 patients with cardiac arrest, of whom159 or59.1% have been treated in2010, and110 patients or40.9% in2011.Of the269 patients treated in the emergency centre,93 or34.6% have exited lethally in the emergency centre, and176 or 65.4% have been transferred to other clinics.In the total number of patients with cardiac arrest, males have dominated with186 cases, or69.1%.The average age of patients included in the survey was56.7 year oldSD±16.0 years.Of the269 patients with cardiac arrest, defibrillation has been applied for93 or34.6% of patients.In the outpatient settings defibrillation has been applied for3 or3.2% of patients.Patients were defibrillated with application of one to four shocks. Of27 cases with who have survived cardiac arrest, none of them have suffered cardiac arrest at home,3 or11.1% of them have suffered cardiac arrest on the street, and24 or88.9% of them have suffered cardiac arrest in the hospital.5 out of27 patients survived have ended with neurological impairment.Cardiac arrest cases were present during all days of the week, but frequently most reported cases have been onMonday with32.0% of cases, and onFriday with24.5% of cases. Conclusions:All survivors from cardiac arrest have received appropriate medical assistance within10 min from attack, which implies that if cardiac arrest occurs near an institution health care(with an opportunity to provide the emergent health care) the rate of survival is higher.

    The purpose of this review is to give an overview of the rehabilitation measures provided for cardiac patients in Germany and to outline its legal basis and outcomes. In Germany the cardiac rehabilitation system is different from rehabilitation measures in other European countries. Cardiac rehabilitation in Germany since 1885 is based on specific laws and the regulations of insurance providers. Cardiac rehabilitation has predominantly been offered as an inpatient service, but has recently been complemented by outpatient services. A general agreement on the different indications for offering these two services has yet to be reached. Cardiac rehabilitation is mainly offered after an acute cardiac event and bypass surgery. It is also indicated in severe heart failure and special cases of percutaneous coronary intervention. Most patients are men (>65%) and the age at which events occur is increasing. The benefits obtained during the 3-4 weeks after an acute event, and confirmed in numerous studies, are often later lost under 'usual care' conditions. Many attempts have been made by rehabilitation institutions to improve this deficit by providing intensive aftercare. One instrument set up to achieve this is the nationwide institution currently comprising more than 6000 heart groups with approximately 120000 outpatients. After coronary artery bypass grafting or acute coronary syndrome cardiac rehabilitation can usually be started within 10 days. The multidisciplinary rehabilitation team consists of cardiologists, psychologists, exercise therapists, social workers, nutritionists and nurses. The positive effects of cardiac rehabilitation are also important economically, for example, for the improvement of secondary prevention and vocational integration. PMID:17301623

    Ranolazine utilization in the management of refractory angina has been established by multiple randomized clinical studies. However, there is growing evidence showing an evolving role in the field of cardiac arrhythmias. Multiple experimental and clinical studies have evaluated the role of ranolazine in prevention and management of atrial fibrillation, with ongoing studies on its role in ventricular arrhythmias. In this review, we will discuss the pharmacological, experimental, and clinical evidence behind ranolazine use in the management of various cardiac arrhythmias. PMID:26459200

    Cardiac tumours in infancy are rare and are mostly benign with rhabdomyomas, fibromas and teratomas accounting for the majority. The presentation depends on size and location of the mass as they tend to cause cavity obstruction or arrhythmias. Most rhabdomyomas tend to regress spontaneously but fibromas and teratomas generally require surgical intervention for severe haemodynamic or arrhythmic complications. Other relatively rare cardiac tumours too are discussed along with an Indian perspect...

    Full Text Available Long procedure time and somewhat suboptimal results hinder the widespread use of catheter ablation of complex arrhythmias such as atrial fibrillation (AF. Due to lack of contrast differentiation between the area of interest and surrounding structures in a moving organ like heart, there is a lack of proper intraprocedural guidance using current imaging techniques for ablation. Cardiac image registration is currently under investigation and is in clinical use for AF ablation. Cardiac image registration, which involves integration of two images in the context of left atrium (LA, is intermodal, with the acquired image and the real-time reference image residing in different image spaces, and involves optimization, where one image space is transformed into the other. Unlike rigid body registration, cardiac image registration is unique and challenging due to cardiac motion during the cardiac cycle and due to respiration. This review addresses the basic principles of the emerging technique of registration and the inherent limitations as they relate to cardiac imaging and registration.

    CD4(+) T cell activation plays a key role in facilitating wound healing after myocardial infarction (MI). Exosomes (EXs) secreted from dendritic cells (DCs) can activate T cells in tumor models; however, whether DEXs (DC-EXs) can mediate CD4(+) T cell activation and improve wound healing post-MI remains unknown. This study sought to determine whether DEXs mediate CD4(+) T cell activation and improve cardiac function post-MI in mice. We used supernatants of hypoxic primary or necrotic HL-1 cardiomyocytes to simulate the post-MI cardiomyocyte microenvironment in vitro. Cultured bone marrow-derived DCs (BMDCs) from mice were stimulated with the supernatants of normal (Control group), hypoxic primary or necrotic HL-1 cardiomyocytes (MI group); a subset of BMDCs remained unstimulated (Negative group). DEXs were then isolated from the BMDC supernatants and either incubated with CD4(+) T cells or injected into mice via the tail vein. In this study, we found that the supernatants of both hypoxic primary and necrotic HL-1 cardiomyocytes upregulate DC maturation markers. After the injection of DEXs, a greater number of MI-DEXs are recruited by the mouse spleen and with greater rapidity than control- or negative-DEXs. Confocal imaging and flow cytometry revealed that MI-DEXs exhibited higher uptake by splenic CD4(+) T cells than the control- and negative-DEXs, and this increase was correlated with significantly greater increases in the expression of chemokines and the inflammatory cytokines IFN-γ and TNF by the CD4(+) T cells in vitro and in vivo. In addition, the injection of MI-DEXs improved cardiac function in mice post-MI. These results suggest that DEXs could mediate the activation of CD4(+) T cells through an endocrine mechanism and improve cardiac function post-MI. Our findings provide the basis for a novel strategy for the treatment of MI through the systemic delivery of DEXs. PMID:26746143

    Out-of-hospital cardiac arrest (OHCA) constitutes a major health care problem with the development in immediate survivors of a post-cardiac arrest syndrome including systemic inflammatory response as observed in sepsis. As a decreased monocyte HLA-DR expression (mHLA-DR) has been repeatedly described in septic patients in association with an increased risk of death and nosocomial infections, we tested whether this immune alteration could also be observed after OHCA. Fifty-five non-shockable OHCA patients sampled at Day 0 (D0: within 4 h after OHCA), D1 (the next day), and D3: (after 2 additional days) were included. CD4+ lymphocyte count and mHLA-DR were evaluated by flow cytometry. We observed a marked decrease in mHLA-DR as early as D0 in patients compared with normal values. This decrease persisted till D3 and was associated with a moderate decrease in the number of circulating CD4+ lymphocytes. No correlations were identified between mHLA-DR and usual prognostic markers after OHCA. However, overtime evolution in mHLA-DR values appeared different between survivors and non-survivors with a quasisystematic decrease between D1 and D3 in non-survivors versus an increased expression in survivors. In conclusion, this preliminary pilot study describes the occurrence of OHCA-induced immune alterations as illustrated by a decreased mHLA-DR and CD4+ lymphopenia. Furthermore, we show for the first time the differential overtime evolution in mHLA-DR between survivors and non-survivors without association with usual prognostic markers and multiple organ failure. These initial results should now be confirmed in a larger cohort of OHCA patients. PMID:26796574

  15. Postoperative cardiac arrest due to cardiac surgery complications

    To examine the role of anesthetists in the management of cardiac arrest occurring in association with cardiac anesthesia. In this retrospective study we studied the potential performances for each of the relevant incidents among 712 patients undergoing cardiac operations at Golestan and Naft Hospitals Ahwaz between November 2006 and July 2008. Out of total 712 patients undergoing cardiac surgery, cardiac arrest occurred in 28 cases (3.9%) due to different postoperative complications. This included massive bleeding (50% of cardiac arrest cases, 1.9% of patients); pulseless supra ventricular tachycardia (28.5% of cardiac arrest cases, 1.1% of patients); Heart Failure (7% of cardiac arrest cases, 0.2% of patients); Aorta Arc Rapture (3.5% of cardiac arrest cases, 0.1% of patients); Tamponade due to pericardial effusion (3.5% of cardiac arrest cases, 0.1% of total patients); Right Atrium Rupture (3.5% of cardiac arrest cases, 0.1% of patients) were detected after cardiac surgery. Out of 28 cases 7 deaths occurred (25% of cardiac arrest cases, 0.1% of patients). The most prevalent reason for cardiac arrest during post operative phase was massive bleeding (50%) followed by pulseless supra ventricular tachycardia (28.5%). Six patients had some morbidity and the remaining 15 patients recovered. There are often multiple contributing factors to a cardiac arrest under cardiac anesthesia, as much a complete systematic assessment of the patient, equipment, and drugs should be completed. We also found that the diagnosis and management of cardiac arrest in association with cardiac anesthesia differs considerably from that encountered elsewhere. (author)

    Quercetin is an important dietary flavonoid present in fruits and vegetables and has attracted attention because of its anti-inflammatory and anti-oxidative properties. Inflammation and oxidative stress play important roles in posttraumatic cardiomyocyte apoptosis, which contributes to secondary cardiac dysfunction. This study investigates the protective effect of quercetin on trauma-induced secondary cardiac injury and the mechanisms involved. Widely accepted nonlethal mechanical trauma models were established. In vivo, cardiomyocyte apoptosis and cardiac dysfunction in rats were assessed using TUNEL staining and a biological mechanic experiment system. In vitro, cell viability, tumour necrosis factor-α (TNF-α), reactive oxygen species (ROS) and [Ca(2+)]i of H9c2 cells were detected using an MTT assay, ELISA, and 2',7'-dichlorofluorescin diacetate and fluo-4 acetoxymethyl ester assays respectively. Quercetin pretreatment (20 mg/kg i.p.; 0.5 h before trauma) significantly improved posttraumatic cardiomyocyte apoptosis and cardiac dysfunction. Pretreatment with quercetin (20 μM; 24 h before trauma plasma addition) significantly attenuated trauma-induced viability decreases, TNF-α increases, ROS overproduction and [Ca(2+)]i overload in H9c2 cells. In conclusion, quercetin may reverse posttraumatic cardiac dysfunction by reducing cardiomyocyte apoptosis through the suppression of TNF-α increases, ROS overproduction and Ca(2+) overload in cardiomyocytes, representing a potential preventive approach for the treatment of secondary cardiac injury after mechanical trauma.

    Full Text Available Abstract Background: Tobacco smoke exposure is an important risk factor for cardiac remodeling. Under this condition, inflammation, oxidative stress, energy metabolism abnormalities, apoptosis, and hypertrophy are present. Pentoxifylline has anti‑inflammatory, anti-apoptotic, anti-thrombotic and anti-proliferative properties. Objective: The present study tested the hypothesis that pentoxifylline would attenuate cardiac remodeling induced by smoking. Methods: Wistar rats were distributed in four groups: Control (C, Pentoxifylline (PX, Tobacco Smoke (TS, and PX-TS. After two months, echocardiography, invasive blood pressure measurement, biochemical, and histological studies were performed. The groups were compared by two-way ANOVA with a significance level of 5%. Results: TS increased left atrium diameter and area, which was attenuated by PX. In the isolated heart study, TS lowered the positive derivate (+dp/dt, and this was attenuated by PX. The antioxidants enzyme superoxide dismutase and glutathione peroxidase were decreased in the TS group; PX recovered these activities. TS increased lactate dehydrogenase (LDH and decreased 3-hydroxyacyl Coenzyme A dehydrogenases (OH-DHA and citrate synthase (CS. PX attenuated LDH, 3-OH-DHA and CS alterations in TS-PX group. TS increased IL-10, ICAM-1, and caspase-3. PX did not influence these variables. Conclusion: TS induced cardiac remodeling, associated with increased inflammation, oxidative stress, apoptosis, and changed energy metabolism. PX attenuated cardiac remodeling by reducing oxidative stress and improving cardiac bioenergetics, but did not act upon cardiac cytokines and apoptosis.

  19. Psychological depression and cardiac surgery: a comprehensive review.

    2012-12-01

    The psychological and neurological impact of cardiac surgery has been of keen empirical interest for more than two decades although reports showing the prognostic influence of depression on adverse outcomes lag behind the evidence documented in heart failure, myocardial infarction, and unstable angina. The paucity of research to date is surprising considering that some pathophysiological mechanisms through which depression is hypothesized to affect coronary heart disease (e.g., platelet activation, the inflammatory system, dysrhythmias) are known to be substantially influenced by the use of cardiopulmonary bypass. As such, cardiac surgery may provide a suitable exemplar to better understand the psychiatric mechanisms of cardiopathogenesis. The extant literature is comprehensively reviewed with respect to the deleterious impact of depression on cardiac and neuropsychological morbidity and mortality. Research to date indicates that depression and major depressive episodes increase major cardiovascular morbidity risk after cardiac surgery. The association between depressive disorders and incident delirium is of particular relevance to cardiac surgery staff. Contemporary treatment intervention studies are also described along with suggestions for future cardiac surgery research. PMID:23441564

    Cardiac failure has become a major but underestimated public health problem. The EPICAL study in France confirmed the severity of this condition. In addition to the neuro-hormones, the role played by inflammatory cytokines in the progression of the disease has been emphasized. The importance of the "genetic background" in the development and evolution of cardiac failure has been demonstrated (deletion or prospective polymorphism). From the therapeutic point of view, besides the hopes raised by multisite pacing, the betablockers and spironolactone have been shown to provide major functional improvement and prolonged survival, and they take their place with the angiotensin converting enzyme inhibitors in our pharmacological arsenal. Cellular transplantation is associated with encouraging pre-clinical results which open up a new field of interest. Finally, global management, including physical rehabilitation and patient education by plury-disciplinary teams, provides medical and economic benefits. The year 1999 has been particularly rich in the field of cardiac failure from the basis of fundamental research to the organisation of health care. PMID:10721444

  3. Systemic inflammatory response following acute myocardial infarction

    2015-01-01

    Acute cardiomyocyte necrosis in the infarcted heart generates damage-associated molecular patterns, activating complement and toll-like receptor/interleukin-1 signaling, and triggering an intense inflammatory response. Inflammasomes also recognize danger signals and mediate sterile inflammatory response following acute myocardial infarction (AMI). Inflammatory response serves to repair the heart, but excessive inflammation leads to adverse left ventricular remodeling and heart failure. In addition to local inflammation, profound systemic inflammation response has been documented in patients with AMI, which includes elevation of circulating inflammatory cytokines, chemokines and cell adhesion molecules, and activation of peripheral leukocytes and platelets. The excessive inflammatory response could be caused by a deregulated immune system. AMI is also associated with bone marrow activation and spleen monocytopoiesis, which sustains a continuous supply of monocytes at the site of inflammation. Accumulating evidence has shown that systemic inflammation aggravates atherosclerosis and markers for systemic inflammation are predictors of adverse clinical outcomes (such as death, recurrent myocardial in-farction, and heart failure) in patients with AMI.

    Full Text Available The pyometra is a disease that affects middle age and elderly female dogs during diestrus. Hormonal, microbiological, biochemical and hematological aspects are well described. However, few studies have evaluated the role of each in the prognosis of canine pyometra. The aim of this study was to identify markers associated with clinical worsening of dogs with pyometra. We prospectively evaluated 80 dogs with pyometra treated surgically. Group 1 consisted of dogs that were discharged within 48 hours after surgery and Group 2 consisted of those who required prolonged hospitalization or died. The findings of hematological, biochemical and blood lactate levels were compared between groups and variables such as bacterial multidrug resistance, systemic inflammatory response syndrome (SIRS, hyperlactatemia and increased creatinine were analyzed through the dispersion of frequencies between groups. Among the variables studied, the presence of SIRS and elevated serum creatinine >2.5mg/mL were effective in predicting the worsening of the disease and can be used as prognostic markers of canine pyometra.

    Full Text Available Macrophages are an immune cell type found in every organ of the body. Classically, macrophages are recognised as housekeeping cells involved in the detection of foreign antigens and danger signatures, and the clearance of tissue debris. However, macrophages are increasingly recognised as a highly versatile cell type with a diverse range of functions that are important for tissue homeostasis and injury responses. Recent research findings suggest that macrophages contribute to tissue regeneration and may play a role in the activation and mobilisation of stem cells. This review describes recent advances in our understanding of the role played by macrophages in cardiac tissue maintenance and repair following injury. We examine the involvement of exogenous and resident tissue macrophages in cardiac inflammatory responses and their potential activity in regulating cardiac regeneration.

    Full Text Available Cardiac inflammatory myofibroblastic tumor (IMT is a rare entity and is associated with distinct clinical, pathological and molecular features. The clinical behavior, natural history, biological potential, management and prognosis of such tumors are unclear. We present herewith an adolescent girl who presented with similar entity involving the junction of the right atrium and the inferior vena cava (IVC in association with thrombocytosis and IVC thrombosis leading to obstruction of blood flow. Diagnostic tools included imaging and immuno-histopathology studies. Surgical management included resection of the tumor and thrombo-embolectomy of the IVC under cardiopulmonary bypass. This case is unique due to association of complete obstruction of IVC caused by the strategic location of the tumor, thrombosis of vena cava and association of thrombocytosis. These features have not been reported yet in relation to the cardiac IMT. This report will help in better understanding and management of similar cases in terms of planning cannulation of femoral veins or application of total hypothermic circulatory arrest during cardiopulmonary bypass and prompt us to look for recurrence or metastasis during follow up using echocardiography and laboratory investigations. The possibility of IMT should be kept in the differential diagnosis of cardiac tumors especially in children and adolescents.

    Tamoxifen-inducible Cre-mediated manipulation of animal genomes has achieved wide acceptance over the last decade, with numerous important studies heavily relying on this technique. Recently, a number of groups have reported transient complications of using this protocol in the heart. In the present study we observed a previously unreported focal fibrosis and depressed left-ventricular function in tamoxifen-treated αMHC-MerCreMer-positive animals in a Tβ4shRNAflox × αMHC-MerCreMer cross at 6–7 weeks following standard tamoxifen treatment, regardless of the presence of the floxed transgene. The phenotype was reproduced by treating mice from the original αMHC-MerCreMer strain with tamoxifen. In the acute phase after tamoxifen treatment, cell infiltration into the myocardium was accompanied by increased expression of pro-inflammatory cytokines (IL-1β, IL-6, TNFα, IFNγ, Ccl2 and markers of hypertrophy (ANF, BNP, Col3a1. These observations highlight the requirement for including tamoxifen-treated MerCreMer littermate controls to avert misinterpretation of conditional mutant phenotypes. A survey of the field as well as the protocols presented here suggests that controlling the parameters of tamoxifen delivery is important in avoiding the chronic MerCreMer-mediated cardiac phenotype reported here.

    2013-01-01

    Curcumin (diferuloylmethane), a yellow coloring agent extracted from turmeric is also used as a remedy for the treatment and prevention of inflammatory diseases. Acute and chronic inflammation is a major factor in the progression of obesity, type II diabetes, arthritis, pancreatitis, cardiovascular, neurodegenerative and metabolic diseases, as well as certain types of cancer. Turmeric has a long history of use in Ayurvedic medicine for the treatment of inflammatory disorders. Recent studies on the efficacy and therapeutic applicability of turmeric have suggested that the active ingredient of tumeric is curcumin. Further, compelling evidence has shown that curcumin has the ability to inhibit inflammatory cell proliferation, invasion, and angiogenesis through multiple molecular targets and mechanisms of action. Curcumin is safe, non-toxic, and mediates its anti-inflammatory effects through the down-regulation of inflammatory transcription factors, cytokines, redox status, protein kinases, and enzymes that all promote inflammation. In addition, curcumin induces apoptosis through mitochondrial and receptor-mediated pathways, as well as activation of caspase cascades. In the current study, the anti-inflammatory effects of curcumin were evaluated relative to various chronic inflammatory diseases. Based on the available pharmacological data obtained from in vitro and in vivo research, as well as clinical trials, an opportunity exists to translate curcumin into clinics for the prevention of inflammatory diseases in the near future.

    Embryonic stem cell (ESC) markers are molecules specifically expressed in ES cells. Understanding of the functions of these markers is critical for characterization and elucidation for the mechanism of ESC pluripotent maintenance and self-renewal, therefore helping to accelerate the clinical application of ES cells. Unfortunately, different cell types can share single or sometimes multiple markers; thus the main obstacle in the clinical application of ESC is to purify ES cells from other type...
