Polycystic ovary syndrome (PCOS) affects one in ten women of reproductive age, painting a complex picture of metabolic dysfunction. Its hallmark triad includes irregular menstrual cycles, androgen excess, and polycystic ovaries. Beyond infertility concerns, PCOS carries a heavy burden of metabolic imbalances, often characterized by insulin resistance, dyslipidemia, and chronic low-grade inflammation. These intertwined factors place women with PCOS at increased risk for type 2 diabetes and cardiovascular disease, posing a significant long-term health challenge. Current first-line treatments like metformin focus mainly on managing insulin resistance and regulating menstrual cycles. However, unmet needs remain in addressing the broader metabolic derangements and preventing associated health complications. In light of this, glucagon-like peptide-1 (GLP-1) analogs have emerged as potential game-changers in the PCOS treatment landscape. Their multifaceted effects on metabolism beyond blood sugar regulation offer a promising avenue for optimizing care and improving long-term health outcomes in women with PCOS. This meta-analysis aims to evaluate the use of GLP-1 analogs on patients with PCOS to reduce body mass index (BMI), glycated hemoglobin (HbA1C), fasting blood glucose (FBG), high density lipid (HDL), low density lipid (LDL) and triglyceride. PubMed, Embase, and Cochrane databases were systematically searched for randomized controlled trials (RCT) comparing the use of GLP-1 analogs to placebo or other therapies in patients with PCOS. Treatment effects for continuous endpoints were pooled through mean differences (MD) with 95% confidence intervals. Heterogeneity was evaluated with the Cochran Q test, the prediction interval and I² statistics. Statistical analysis was performed in Revman 5.4. The results were reported following the Preferred Reporting Items for Systematic Review (PRISMA) guidelines.A total of 4 RCTs with 228 patients were included, of whom 137 were randomized to GLP-1 therapy, 58 to placebo, and 33 to other treatments. Over a mean follow-up time of 24 weeks, patients submitted to GLP-1 analogs presented significant decreases in HbA1C (MD -1.40%; 95% CI -1.64 to -1.16; p<000001; I²=0% ), FBG (MD -4.40 mg/dL; 95% CI -7.63 to -1.17; p=0.008; I²=0%) and HDL-c (MD -0.82 mg/dL; 95% CI -1.33 to -0.31; p=0.002; I²=3%); and a nonsignificant increase in LDL-c (MD 0.37 mg/dL; 95% CI -1.30 to 2.03; p=0.67; I²=0%); and nonsignificant decrease in BMI (MD -1.28 Kg/m²; 95% CI -3.18 to 0.63; p=0.19; I²=98%), and triglyceride (MD -10.50 mg/dL; 95% CI -22.81 to 1.81; p=0.09; I²=0%).In this meta-analysis of RCTs of patients with PCOS, the use of GLP-1 analogs showed a significant reduction in HbA1C, FBG, and HDL-c. A larger sample size of people are needed for further statistical analyses. Presentation: 6/3/2024
