title: Probiotic supplementation and the effects on weight loss, glycaemia and lipid profiles in women with polycystic ovary syndrome: a randomized, double-blind, placebo-controlled trial.
abstract: The aim of the current study was to assess the effects of probiotic supplementation on weight loss, glycaemia and lipid profiles in women with polycystic ovary syndrome (PCOS). In a randomized, double-blind, placebo-controlled trial, 60 women with PCOS were randomized to receive probiotic capsule (n = 30) or placebo (n = 30) for 12 weeks. Consumption of probiotic supplements resulted in a significant reduction in weight (-0.5 ± 0.4 vs. +0.1 ± 1.0 kg, p = 0.004) and BMI (-0.2 ± 0.2 vs. +0.03 ± 0.4 kg/m2, p = 0.004) compared with the placebo. In addition, compared with the placebo, probiotic administration was associated with a significant decrease in fasting plasma glucose (-2.4 ± 8.4 vs. +2.1 ± 7.0 mg/dL, p = 0.02), serum insulin concentrations (-2.0 ± 5.8 vs. +1.6 ± 5.0 μIU/mL, p = 0.01), homoeostasis model of assessment-insulin resistance (-0.5 ± 1.4 vs. +0.3 ± 1.1, p = 0.01), homoeostatic model assessment-beta cell function (-7.5 ± 22.3 vs. +6.3 ± 21.7, p = 0.01), serum triglycerides (-13.3 ± 51.3 vs. +13.6 ± 37.1 mg/dL, p= 0.02) and a significant increase in quantitative insulin sensitivity check index (QUICKI) (+0.006 ± 0.01 vs. -0.005 ± 0.02, p = 0.01). When we adjusted the analysis for baseline values of biochemical parameters, age and baseline BMI, except for QUICKI (p = 0.08), other findings did not alter. We found that probiotic supplementation among PCOS women for 12 weeks had favourable effects on weight loss, markers of insulin resistance, triglycerides and VLDL-cholesterol concentrations.
