The adipokines leptin, adiponectin, tumor necrosis factor-alpha (TNF-α), and interleukin 6 (IL-6) might be associated with metabolic syndrome (MetS) in patients with schizophrenia. In the present study, we attempted to confirm the results of previous reports and assessed their MetS-related correlation with body fat composition and biochemical parameters. We measured in 46 patients with schizophrenia and MetS serum levels of adiponectin insulin, leptin, TNF-α and IL-6 and compared these levels to those of patients with schizophrenia without MetS. The MetS patients had significantly increased leptin levels and leptin/adiponectin ratios, as well as decreased adiponectin levels. Leptin levels correlated with several metabolic parameters, both in patients with and without MetS, including body fat percentage, total fat fold, and body mass index (BMI). Patients without abnormal MetS components had lower levels of leptin and leptin/adiponectin ratios compared with patients who had one or two MetS components. Leptin/adiponectin ratios were higher in patients who had four rather than three MetS components. Multiple regression analysis revealed multiple associations for leptin but only one for adiponectin, TNF-α, and IL-6. Our results support an important pathophysiological role for leptin more than adiponectin in patients with schizophrenia with MetS.

Abstract Background Oxidative stress and inflammation are primarily implicated in the development and progression of liver injury during cholestasis. Selenium, a known essential antioxidant trace element, was found to provide a remarkable antioxidant and anti-inflammatory effects on various diseases. Aim This study was planned to evaluate the possible protective effect of selenium supplementation in a rat model of chronic cholestasis. Design Experimental study. Methods This study was carried out on adult male rats allocated randomly into sham, bile duct ligated (BDL), and BDL-selenium treated (BDL-Se) groups. Sodium selenite was given by gavage daily, in a dose of 100 µg/kg for 6 weeks, starting 2 weeks before the BDL. Results BDL group presented a significant increase in serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and liver levels of malondialdehyde (MDA), tumor necrosis factor alpha (TNF-α), and transforming growth factor beta 1(TGF-β1), associated with a significant decrease in serum levels of total proteins (TP) compared to sham group . Selenium supplementation significantly lowered serum levels of AST, ALT, ALP, and liver levels of MDA, TNF-α, and TGF-β1 along with a significant increase in serum TP in BDL-Se group versus BDL rats. Histological analysis of liver showed a significant attenuation of the inflammatory score and a significant decrease in the percentage area of collagen deposition in BDL-Se group versus BDL rats. Conclusion Selenium supplementation reduces liver injury and improves liver functions in experimental cholestasis probably by its antioxidant and anti-inflammatory activities, which further alleviate the liver fibrosis.

Abstract Background Angiography is a safe cardiovascular technique for the diagnosis and treatment of the cardiovascular disorders. The potential effects of angiography on the cytokines are yet to be clarified completely. Interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-α) are the important pro-inflammatory cytokines that participate in the pathogenesis of artery stenosis. The aim of his project was to study the angiography effects on the serum levels of IL-8 and TNF-α. Methods Fifty-five participants in three groups, without, with one and with more than one artery stenosis, were explored in this project. Serum levels of IL-8 and TNF-α were measured in the participants before and after angiography using enzyme linked immunosorbent assay (ELISA) technique. Results Serum levels of IL-8, but not TNF-α, were significantly decreased following angiography. X-ray doses had moderate positive correlation with serum levels of TNF-α in the patients with more than one artery stenosis. Serum levels of IL-8 and TNF-α were not different among male and female participants in all groups. Discussion Angiography may be a protective factor for inflammation in IL-8 dependent manner. Using angiography in the patients with more than one artery stenosis needs to be executed cautiously.

AbstractMany studies tried to assess the relationship between -308G/A polymorphism of tumor necrosis factor alpha (TNF-α) gene and risk of metabolic syndrome (MS), but their results were contradictory. This meta-analysis aimed to precisely evaluate this association. A systematic literature search was performed in Pubmed database and WanFang Med Online, STATA software 14.0 was used for the meta-analysis. Eleven independent studies containing 3277 cases and 3312 controls were included in our meta-analysis. In overall analysis, significant association was found between -308G/A polymorphism of TNF-α and MS in both allele model (OR 1.47, 95% CI 1.09–1.98, P 0.013) and dominant model (OR 1.77, 95% CI 1.21–2.58, P 0.003). In the subgroup analysis, the A allele was associated with increased risk of MS in Asia group (allele model: OR 1.82 95% CI 1.31–2.53, P < 0.001; dominant model: OR 2.30, 95% CI 1.64–3.21 P < 0.001; homozygous model: OR 2.29, 95% CI 1.31–4.01, P 0.004), and decreased risk of MS in Europe group (dominant model: OR 0.83, 95% CI 0.70–0.99, P < 0.001; recessive model: OR 0.51, 95% CI 0.28–0.92, P 0.025; homozygous model: OR 0.49 95% CI 0.27–0.89, P 0.02). The A allele also appeared to linked to increased risk of MS in CDS group and IDF groups. No significant association was observed in NCEPATPIII group. Our results suggested that -308G/A of TNF-α gene was a risk factor for MS, but it may played different roles in different ethnics, further studies with larger sample size and more other ethnics should be performed to confirm our conclusions.

Background Inflammation plays a major role in the development of metabolic syndrome (MetS) and its progression. Recent studies have shown that pentraxin-3 (PTX-3), osteoprogerin (OPG), and tumor necrosis factor-alpha (TNF-α) are key factors in MetS pathophysiology, but evidence for endorsing their clinical use is currently unclear and insufficient. Aim The study aimed to evaluate the association between the inflammatory biomarkers’ levels and the severity of MetS. Methods The study was observational, transversal, prospective, cohort, and analytical type. We enrolled 80 patients (M:F = 1, mean age = 55 ± 10.77 years) who met MetS criteria. The study protocol included: medical history, physical examination, 6-min walk test distance (6MWTD), biochemical tests, electrocardiogram, echocardiography, and carotid ultrasonography. We also performed plasmatic measurement of PTX-3, OPG, and TNF-α, in addition to standard biochemical tests. Results Subjects with severe MetS had higher values of body mass index (BMI) and waist circumference (p < 0.001, p = 0.001). PTX-3 levels were significantly higher in patients with severe MetS (p = 0.03) and the values were not influenced by age or gender. OPG positively correlated with BMI (r = 0.264, p = 0.018). 6MWTD was lower in patients with severe MetS (p = 0.005), whereas CCA-IMT was higher in this group of patients (p = 0.005). In addition, the receiver operating characteristic (ROC) curve analysis for PTX-3 identified a cut-off value of 10.7 ng/dl that differentiates between mild and severe MetS [AUC 0.656; sensitivity =47.1% (95% CI = 36.1%–62.3%); specificity = 78.9% (95% CI = 54.4%–93.9%)]. Conclusion PTX-3 was correlated with the severity of MetS, with other inflammatory parameters and cardiovascular tests. CCA-IMT and 6MWTD are useful in differentiating between mild and severe MetS.

Abstract Objective: The aim of this study was to evaluate serum levels of interleukin (IL)-17, IL-6, and tumor necrosis factor alpha (TNF-α) in RA patients and to assess the correlation of these cytokines with clinical and laboratory parameters. Materials and Methods: 48 patients with RA and 35 healthy volunteers were enrolled in the study. Disease activity was determined by disease activity score (DAS28) in patients with RA. Patients with RA were categorized as mild (DAS28≤3.2), moderate (3.2<DAS28≤5.1), and severe (5.1<DAS28) according to DAS28. The serum levels of IL-17, IL-6 and TNF-α cytokines were measured by enzyme-linked immuno sorbent assay. Results: The mean serum IL-17 and TNF-α levels did not differ between RA patients and controls (P>0.05). Serum IL-6 levels were significantly elevated in RA patients compared with controls (P<0.001). The increasing trend in mean serum IL-6 levels across group with mild, moderate, and severe disease activity was significant (P<0.001, respectively). In RA patients, serum IL-6 concentrations were significantly correlated with ESR, CRP, DAS28, and VAS (r=0.371, P=0.009; r=0.519, P<0.001; r=0.536, P<0.001; r=0.539, P<0.001, respectively). Also, Serum IL-17 concentrations demonstrated significant correlations with ESR, CRP, but not DAS28 (r=0.349, P=0.015; r=0.299, P=0.039; r=0.274, P=0.060, respectively). Serum TNF-α showed no significant correlation with disease activity indices. Conclusions: This study showed that patients with RA had significantly increased cytokine level for IL-6, but not IL-17 and TNF-α and high level of serum IL-6 cytokine was associated with disease activity. However, further follow-up studies involving large samples are required to clarify precise role of these cytokines in disease development and progress.

The objective of this study was to evaluate the peripheral expression of inflammatory markers in adolescents with different nutritional status and its correlation with parameters of the metabolic syndrome. Seventy-two female postpubescent adolescents were divided into 3 groups: eutrophic (Co), eutrophic with a high body fat percentage (HBF), and overweight (OW). Data related to the parameters of the metabolic syndrome and the peripheral expression of tumour necrosis factor (TNF)-α, interleukin (IL)-6, and IL-10 were evaluated. Higher values of glycemia and insulin resistance were found in the HBF group than in the Co group. No differences related to the peripheral expression of the cytokines were found among the groups. In the HBF group, a positive correlation was observed between TNF-α and IL-6, IL-10 and the proinflammatory cytokines, and IL-6 and glycemia. In the OW group, a positive correlation was found between IL-6 and triglycerides. Adolescents with normal weight but body fat excess present a metabolic profile and body composition similar to those of overweight adolescents. This suggests that these adolescents have a risk of developing cardiovascular diseases similar to that of overweight adolescents. The positive correlation between IL-10 and TNF-α and IL-6 suggests an attempt to inhibit the production of these cytokines by IL-10.

In this paper, we propose a model for predicting the risk of severe chronic generalized periodontitis (GCP) in patients with metabolic syndrome based on the levels of tumor necrosis factor alpha (TNF-α) in the periodontal pocket exudate. The analysis of oral cavity cytokine profiles conducted in 537 patients with GCP and comorbid metabolic syndrome showed that increased TNF-α correlated with the severity of GCP: higher levels of TNF-α were observed in patients whose condition was more severe. The prognostic model built in Statistica. 10 allowed us to use TNF-α as a prognostic criterium for GCP severity. We determined the cut-off point above which a high risk of severe GCP can be concluded with 91.2% sensitivity and 70.8% specificity. The spreadsheet in Microsoft Exсel 2010 automatically computed the risk of severe GCP from a patient’s TNF-α concentrations in the PP, which makes the model convenient for routine clinical use in dentistry.

BACKGROUND: Renal dysfunction is very common in patients with advanced liver cirrhosis and portal hypertension. The development of renal failure in the absence of clinical, anatomical or pathological causes renal of failure is termed hepatorenal syndrome (HRS).AIM: The present study was constructed to investigate the possible protective effects of nebivolol (Nebi) against D-galactosamine (Gal)-induced HRS in rats.MATERIAL AND METHODS: Rats were treated with Nebi for ten successive days. On the 8th day of the experiment, they received a single dose of Gal. Serum levels of Cr, BUN, Na+ and K+ as well as AST, ALT, total bilirubin (TB), NH3 and endothelin-1 (ET-1) were determined following Gal administration. Moreover, renal and liver contents of MDA, GSH, F2-isoprostanes (F2-IPs), tumor necrosis factor-alpha (TNF-α), nuclear factor kappa-B (NF-кB), total nitric oxide (NO), in addition to activities of caspase-3 (Cas-3), heme oxygenase-1 (HO-1), inducible and endothelial NO synthase (iNOS and eNOS) enzymes were also assessed. Finally, histopathological examination was performed.RESULTS: Nebi attenuated Gal-induced renal and hepatic dysfunction. It also decreased the Gal-induced oxidative stress and inflammatory recruitment.CONCLUSION: Results demonstrated both nephroprotective and hepatoprotective effects of Nebi against HRS and suggested a role of its antioxidant, anti-inflammatory, anti-apoptotic and NO-releasing properties.
