Material and methods: we studied 5 groups of patients: A (n = 20): H (hyperandrogenism) + O (oligoanovulation) + P (polycystic ovary) [classic phenotype];B (n = 17): H + O [classic phenotype but normal ovaries];C (n = 15): H + P [Ovulatory phenotype];D (n = 17): O + P [Normoandrogenic phenotype];and E (n = 16) control group. Body mass index, waist circumference, waist/hip ratio, blood pressure and hirsutism were evaluated. Serum concentrations of adiponectin, insulin, Creactive protein, SHBG, androgens and lipids were measured. Oral glucose tolerance test was performed. Results: there were no differences between the groups in terms of age and BMI. Total cholesterol, LDL-C and triglyceride levels were higher in phenotype A than in C (P P = 0.03). HOMA-IR, insulin and glucose/insulin ratio were significantly higher in phenotypes A and D vs C and E (P P P < 0.05). Conclusions: adiponectin serum concentrations vary according to the phenotypic expression of PCOS. Our results suggest that adiponectin could be used as a biochemical marker to identify phenotypes at increased metabolic risk.展开更多
