Abstract:
Objective To investigate the effects of pioglitazone on serum adipocytokines (leptin, resistin and adiponectin) in polycystic ovary syndrome (PCOS) patients with insulin resistance (IR). Methods Thirty-five PCOS patients with IR were treated with pioglitazone 15mg/d for 12 weeks. The results of ovulation induction were observed. The changes of fasting plasma glucose (FPG), fasting serum insulin (FINS), serum levels of leptin, resistin and adiponectin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), and blood fat were examined at the baseline and after the therapy by enzyme-linked immunosorbentassay (ELISA) and radioimmunoassay (RIA). Results After 12 weeks' treatment, menstruation and rate of ovulation per cycle were improved in 35 (88.5%) PCOS patients with IR. Waist/hip ratio and F-G score were significantly decreased (P<0.05), and BMI declined with no significant difference (P>0.05). The levels of LH, T, FINS, HOMA-IR, total cholesterol, triglyceride and low density lipoprotein-cholesterol were significantly decreased (P<0.01, P<0.05) after treatment; high density lipoprotein-cholesterol level was significantly increased (P<0.01) after treatment. However, there were no significant differences in FSH and FPG (P>0.05). The levels of serum leptin and resistin were decrease than before (P<0.05), and the level of serum adiponectin was increased (P<0.05). Conclusion Pioglitazone can effectively improve clinical syndromes, insulin sensitivity, glucose and lipid metabolism of PCOS patients with IR. Adipocytokines (leptin, adiponectin and resistin) as regulators of insulin metabolism are involved in the pathogenesis of insulin resistance in PCOS. Pioglitazone treatment can decrease plasma glucose level and improve insulin sensitivity at least partly through improving the profiles of adipocytokines.
