چکیده
UNLABELLED Aims/Introduction: Resistin, an inflammatory cytokine, might be involved in the development of atherosclerosis. In a recent paper, we showed that resistin polymorphism might be a risk marker for stroke susceptibility in Japanese type 2 diabetic patients. We tested whether the serum resistin levels might be also a risk marker of stroke independently from RETN polymorphism. MATERIALS AND METHODS Type 2 diabetic outpatients from our hospitals were enrolled. Patients (n = 89) with a history of coronary heart disease and stroke, and randomly selected controls (n = 178) matched for sex and age, but without a history of coronary heart disease and stroke, were examined for polymorphism -420 (C>G) and cytokines levels. RESULTS Serum resistin levels were significantly higher in patients with cardiovascular diseases (CVD) than in those without CVD (P = 0.024), and were highest in patients with stroke among the CVD. In multiple logistic regression analysis, serum resistin levels was an independent risk marker of stroke even after adjusted by RETN polymorphism, age, sex, body mass index, HbA1c, systolic and diastolic blood pressure, triglyceride, low density lipoprotein cholesterol, high density lipoprotein cholesterol, creatinine, history of coronary heart disease, treatment of insulin, sulfonylurea and aspirin (odds ratio 1.33, 95% confidence interval [CI] 1.02-1.73, P = 0.039). The enrolled patients were divided by their serum resistin levels (high or low group) and their genotypes (CC, CG, GG at -420) into six groups. Patients with the GG genotype and high resistin levels showed the highest odds ratio, 5.69 (95% CI 1.24-26.1), compared with the group with CC and low levels. CONCLUSIONS The results suggest that serum resistin levels might be a good marker of susceptibility to stroke as well as RETN polymorphism.

Introdution: Adiponectin is a peptide secreted from fat cells that plays an important role in the development of insulin resistance and type 2 diabetes. A number of single nucleotide polymorphisms in the adiponectin gene are associated with lower adiponectin expression and T2DM. The aim of this study was to determination the frequency of rs 2241766 polymorphism in adiponectin gene and its relat...
