Abstract

Objective: To examine the effect of hypocaloric diet plus sibutramine on body composition, hormonal and metabolic parameters in overweight and obese patients with polycystic ovary syndrome (PCOS). Design: Open-label, randomized study at an outpatient clinic. Patients: A total of 59 overweight and obese (18-39 years old) women with PCOS. Measurements: All patients were placed in a hypocaloric diet plus sibutramine (10 mg per day) for the first month and then on a hypocaloric diet plus sibutramine (10 mg per day, group S) or hypocaloric diet only (group D) for the subsequent 6 months. Body composition, hormonal and metabolic features and insulin sensitivity (oral glucose tolerance test, OGTT) were evaluated at baseline and at 3 and 6 months of treatment. Results: Body weight reduced in both groups but the reduction was greater with sibutramine (-15.4±1.1 vs -11.1±1.9% in groups S and D, respectively, P<0.05). At 6 months, a greater percent of patients lost more than 10% of initial body weight in group S than D (81 vs 52.9%). In both groups, all women with abnormal OGTT at baseline presented normal glucose tolerance after 6 months. Free androgen index (FAI), glucose area under the curve and fasting triglyceride (TG) concentration were reduced after 6 months in group S only (P<0.05). No changes in cardiovascular risk factors, prolactin and hepatic enzymes levels were observed in both groups. Conclusion: A hypocaloric diet and a diet plus sibutramine both result in significant weight loss in overweight and obese women with PCOS. Patients who received sibutramine showed a greater weight loss and improvement in hyperandrogenemia and insulin sensitivity after 6 months of treatment. The amelioration of insulin resistance in this group could not be totally explained by weight loss. Total testosterone, FAI and TG levels reduction could be a possible mechanism. Finally, sibutramine increased compliance to diet and it was well tolerated from these patients.
