Effect of Insulin Sensitizers on Glycemic and Lipid Profile in Patients with Polycystic Ovary Syndrome (PCOS)
Abstract
Introduction: Polycystic ovary syndrome (PCOS) is associated with increased cardiovascular risk later in life. Insulin resistance, common in PCOS, heightens the risk of type 2 diabetes, dyslipidemia, hypertension, and cardiovascular disease. This study explored whether insulin sensitizers could modify traditional cardiovascular risk factors, through influence on insulin resistance. Objectives: To evaluate the impact of Metformin and Myoinositol therapy on glycemic and lipid profiles in PCOS patients, based on body mass index (BMI). Methods: A prospective, randomized clinical study was conducted at the UC for Endocrinology in Skopje (2022-2023). Women aged 18-40 with PCOS (Rotterdam 2003 criteria) were assigned to either Metformin (1500 mg XR) or Myoinositol (2 g + 200 mg folic acid TID) for 6 months. Parameters monitored included BMI, fasting plasma glucose (FPG), HOMA-IR, total cholesterol, LDL-C, HDL-C, triglycerides, lipid accumulation product (LAP), and TG/HDL ratio. Results: Baseline BMI significantly influenced HDL, triglycerides, TG/HDL, and LAP. Myoinositol significantly improved cholesterol regardless of BMI. Among patients with BMI ≥25 kg/m², Metformin significantly reduced FPG (4.65 ± 0.5 vs 5.01 ± 0.3 mmol/L) and HOMA-IR (2.25 ± 0.6 vs 2.94 ± 1.1 mmol/L). HOMA-IR positively correlated with TG/HDL ratio (R=0.2086, p=0.016). Conclusion: Myoinositol improved cholesterol in PCOS patients regardless of BMI. Metformin significantly affected glycemic control in…
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.
