Abstract

Liraglutide (LIRA) treatment is associated with the dose-dependent reduction of weight. Higher doses are more effective than lower doses, although higher doses are also more poorly tolerated. Metformin may enhance the weight-lowering potential of LIRA via the stimulatory modulation of incretin in addition to its direct beneficial effects in PCOS. The aim of the present study was to evaluate whether metformin as an adjunct to low‑dose LIRA affects body weight with increased efficacy compared with low‑dose LIRA alone in obese patients with PCOS. In a 12‑week study, 44 obese women with PCOS were randomly offered either combined treatment (COMBO) with 1,000 mg metformin twice a day and 1.2 mg LIRA once a day, or treatment with 1.2 mg LIRA alone. The primary outcome of treatment was an alteration in the levels of obesity. A total of 43 patients [aged 30.3±4.4 years; body mass index (BMI) 37.2±4.5 kg/m2; mean ± standard deviation] completed the study. The subjects treated with COMBO lost on average 6.2±2.4 kg compared with a 3.8±3.5 kg weight loss in the patients treated with LIRA alone (P=0.024). The BMI decreased by 2.2±0.8 kg/m2 in patients treated with COMBO and by 1.4±1.2 kg/m2 in patients treated with LIRA alone (P=0.024). A clinically significant ≥5% weight reduction was achieved in 59.1% of patients treated with COMBO and 42.9% of patients treated with LIRA alone. Reductions in glucose levels following oral glucose tolerance testing, as well as in androstenedione levels in the COMBO group were significantly greater compared with those in the LIRA group. The side effects were mild and transient in the two treatment groups. A combination of metformin and low‑dose LIRA was more effective than low-dose LIRA alone in reducing body weight in obese patients with PCOS.
