Serum adiponectin and resistin levels in patients with obsessive compulsive disorder

We aimed to investigate the changes in serum adiponectin and resistin levels in patients with obsessive compulsive disorder and control groups. The serum adiponectin and resistin levels of 29 patients (16 females, 13 males) with obsessive compulsive disorder and weight, age and sex-matched 31 healthy controls (17 females, 14 males) were determined. Yale-Brown Obsessive Compulsive Scale (Y-BOCS) was applied to all groups. ELISA method was used to measure adiponectin and resistin levels. The mean adiponectin level was 11.92±2.04 ng/ml and resistin level was 13.23±2.78 ng/ml in obsessive compulsive disorder group, while it was 18.81±5.24 ng/ml and 8.17±2.53 ng/ml in control group. Changes in plasma adiponectin and resistin levels in obsessive compulsive disorder may have implications about possible cardiovascular and metabolic abnormalities seen in obsessive compulsive patients.

Plasma adipokine and inflammatory marker concentrations are altered in obese, as opposed to non-obese, type 2 diabetes patients

Elevated plasma free fatty acid (FFA), inflammatory marker, and altered adipokine concentrations have been observed in obese type 2 diabetes patients. It remains unclear whether these altered plasma concentrations are related to the diabetic state or presence of obesity. In this cross-sectional observational study, we compare basal plasma FFA, inflammatory marker, and adipokine concentrations between obese and non-obese type 2 diabetes patients and healthy, non-obese controls. A total of 20 healthy, normoglycemic males (BMI <30 kg/m²), 20 non-obese (BMI <30 kg/m²) and 20 obese (BMI >35 kg/m²) type 2 diabetes patients were selected to participate in this study. Groups were matched for age and habitual physical activity level. Body composition, glycemic control, and exercise performance capacity were assessed. Basal blood samples were collected to determine plasma leptin, adiponectin, resistin, tumor necrosis factor α (TNFα), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP) and FFA concentrations. Plasma FFA, inflammatory marker (hsCRP, IL-6, TNFα), adipokine (adiponectin, resistin, leptin), and triglyceride concentrations did not differ between non-obese diabetes patients and healthy, normoglycemic controls. Plasma FFA, IL-6, hsCRP, leptin, and triglyceride levels were significantly higher in the obese diabetes patients when compared with the healthy normoglycemic controls (P < 0.05). Furthermore, plasma hsCRP and leptin levels were significantly higher in the obese versus non-obese diabetes patients (P < 0.05). Significant correlations between plasma parameters and glycemic control were observed, but disappeared after adjusting for trunk adipose tissue mass. Elevated plasma leptin, hsCRP, IL-6, and FFA concentrations are associated with obesity and not necessarily with the type 2 diabetic state.

目的 探讨检测血清抵抗素水平用于2型糖尿病诊断的意义,并分析其与胰岛素抵抗的关系. 方法 随机收集2型糖尿病患者117例、健康对照组109例,测定其空腹血糖、空腹胰岛素和抵抗素水平.比较上述指标在糖尿病患者和健康对照人群之间的差异.分析抵抗素用于糖尿病诊断的灵敏度、特异度、正确率和ROC曲线下面积.应用Pearson直线相关分析计算抵抗素与胰岛素抵抗指数的相关性. 结果 2型糖尿病患者的血清抵抗素、空腹血糖、空腹胰岛素及胰岛素抵抗指数均显著高于健康对照组(P<0.01).抵抗素用于糖尿病诊断的灵敏度为70.09%、特异度为64.22%、正确率为67.30%、ROC曲线下面积为0.695,诊断试验的准确度为中等.糖尿病患者的血清抵抗素水平与其胰岛素抵抗指数呈显著正相关(r=0.803,P<0.01). 结论 2型糖尿病的发生可能与抵抗素水平增高有关.检测血清抵抗素可用于糖尿病的辅助诊断,并可作为评价胰岛素抵抗程度的一种新的敏感指标.     

Serum and adipocyte resistin in polycystic ovary syndrome with insulin resistance

BACKGROUND: The aim of this study was to investigate the relationship between resistin and insulin resistance in patients with polycystic ovary syndrome (PCOS). METHODS: We compared serum resistin levels in 17 PCOS women and 10 lean, healthy, age-matched non-PCOS women and also compared levels of insulin receptor (IR), phosphatidylinositol-3 kinase (PI3-kinase), glucose transporter 4 (GLUT4) protein and resistin mRNA in adipocytes isolated from the omental adipose tissue of five of the PCOS patients and five age- and weight-matched, non-PCOS controls, to look for local defects in insulin action in PCOS. RESULTS: The PCOS group was hyperinsulinaemic and displayed an impaired insulin response in a 75 g oral glucose tolerance test and an abnormal homeostasis model insulin resistance index. Serum resistin levels were similar in PCOS patients and controls; however, resistin mRNA levels were 2-fold higher in adipocytes from PCOS patients. No correlation was found between serum resistin levels and either the BMI or testosterone levels. Western blot analysis showed that adipocyte levels of insulin receptor, PI3-kinase, and GLUT4 were respectively decreased by 56, 39.4 and 54% in PCOS patients compared with controls. CONCLUSIONS: These results suggest that overexpression of the resistin gene in adipocytes may be a local determinant factor in the pathogenesis of PCOS.
