Short-term and low-dose liraglutide plus metformin decreased body mass index and insulin resistance more than metformin alone in obese women with polycystic ovary syndrome: An open-label randomized controlled study
Abstract
Background and objectives: Reduction of weight improves different manifestations of polycystic ovary syndrome (PCOS). This study compared the effects of liraglutide plus metformin versus metformin alone on weight loss and metabolic profiles in obese women with PCOS.
Methods: This open-label randomized controlled clinical trial consecutively recruited newly-diagnosed PCOS patients of reproductive age with obesity (body mass index ≥ 27.5 kg/m2). Following randomization into two equal groups, Group-1 received treatment with metformin 1000 mg daily alone while Group-2 was given metformin 1000 mg plus subcutaneous (SC) liraglutide 1.2 mg daily for 12 weeks. Anthropometric, biochemical and hormonal data and ovarian morphology were assessed at baseline and after 12 weeks. Clinical information and side effects were recorded every four weeks after initiation of the treatment. Glucose, lipids, and all hormones were analyzed by glucose oxidase, precipitation method, and chemiluminescent microparticle immunoassay respectively. Insulin resistance was measured by homeostatic model assessment (HOMA-IR).
Results: Study included 30 participants comprising 15 for each group. Among 15 participants, 5 dropped out from the Group-1 and 1 dropped out from the Group-2. The final analysis was done among 24 participants (Gr-1: 10 and Gr-2: 14). Waist and hip circumference (WC, HC) significantly (p <0.05) decreased in patients treated with only metformin. Menstrual irregularity, BMI (body mass index),…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 30 participants or records.
