Özet
Objective: To investigate the relationship between insulin resistance and tumor necrosis (TNF)-α, interleukin (IL)-6, C-reactive protein (CRP) in obese women. Background: Obesity and type 2 diabetes are associated with insulin resistance, the mechanisms of which remain poorly understood. Materials and methods: Forty obese (35.8±9.6 years) and 20 non-obese women (31.1 ±7.7) were recruited between June 2002 and February 2003 at the Okmeydaný Training and Research Hospital, Istanbul, Turkey. The obese group was equally divided into two according ?to their WHR (>0.8 and 0.8). Subjects with blood pressure values higher than 140/90 mmHg, pathological findings on standard 12-lead ECG and leukocytosis and glucose levels >100 mg/dl were excluded. Results: Plasma insulin (p<0.0001) and fasting glucose levels (p<0.0001), and HOMA values (p<0.0001) in the obese group were higher than in the controls. Serum triglyceride and VLDL levels were higher in the obese group (p<0.0001 in both), whereas HDL cholesterol levels were higher in the lean control group (p<0.0001). However, no difference was observed between two groups in terms of total cholesterol and LDL-cholesterol levels. The serum levels of both TNF-α, IL-6and CRP were found elevated in the obese group (p<0.05, p<0.05, p<0.01, respectively). In the subgroup analysis, only the HOMA values and TNF-α levels were found higher in the android obese group (p<0.05 and p<0.0001, respectively). Conclusion: Insulin resistance seems to be one of the major causes of obesity-related complications due to increased secretion of TNF-α, IL-6 and CRP together with android obesity.
