Abstract
CONTEXT: Weight loss remains one of the most important arms in obese patients with polycystic ovary syndrome (PCOS). Further studies are needed to identify the best treatment. OBJECTIVE: To evaluate the effects of exenatide (EXE) on reproductive and metabolic function in overweight/obese (OW/OB) PCOS. DESIGN: This is a 24-week open-label prospective, randomized, clinical study. PATIENTS AND MEASUREMENTS: This study randomized 176 OW/OB women diagnosed with PCOS to receive eitherEXE 10 μg BID (n = 88) or metformin (MET) 1000 mg BID (n = 88) for the first 12 weeks. Then all patients were treated with MET alone during the second 12 weeks. We observed metabolic parameters at 0 and 12 weeks, and then tracked the rate of pregnancy during the second 12 weeks. RESULTS: After the first 12 weeks of intervention, compared with MET, subjects who received EXE had significantly decreased weight (4.29 ± 1.29 kg vs 2.28 ± 0.55 kg, P < .001) and total fat% (4.67 ± 0.09% vs 1.11 ± 0.32%, P < .001), improved the homeostasis model of assessment for insulin resistance (1.30 ± 0.58 vs 0.59 ± 0.12, P < .001) and increased the menstrual frequency ratio (0.62 ± 0.12 vs 0.37 ± 0.01, P < .001). During the second 12 weeks, the rate of natural pregnancy of EXE-treated patients was significantly higher than MET-treated patients (43.60% vs 18.70%, P < .05). CONCLUSIONS: Short-term EXE therapy was linked to significant weight loss and central adiposity reduction, which may further explain the improvements in insulin resistance, inflammatory marker and menstrual cycle, which may contribute to increasing pregnancy rates in OW/OB women with PCOS.
