Abstract

Objective To evaluate the efficacy of combined therapy with metformin and low-dose spironolactone as compared with metformin alone on the clinical and endocrine-metabolic alterations of patients with polycystic ovarian syndrome (PCOS). Background PCOS is the most common endocrinological disorder in reproductive-age women. Thus, at least theoretically, metformin plus spironolactone therapy may be an effective and safe combination for PCOS. Patients and methods A prospective randomized comparative study was carried out on 48 patients with the PCOS in Obstetrics and Gynecology Department, Menoufia University Hospital, and Al-Shohadaa Hospital, Egypt, from the period of May 2016 till January 2018. Detailed history, laboratory investigations, obstetric examination, and follow-up were done. Results Mean hirsutism score and BMI (kg/m2) were 10.8 ± 3.9 and 26.8 ± 2.2, respectively, before treatment, which decreased significantly to 7.6 ± 2.4 and 22.10 ± 1.92, respectively, after 6 months of treatment. Luteinizing hormone, follicle-stimulating hormone, free testosterone, dehydroepiandrosterone sulfate, fasting glucose, fasting insulin, and homeostasis model assessment of insulin resistance were decreased significantly after 6 months of treatment as compared with before treatment among women who received metformin + hypocaloric diet and received metformin + spironolactone + hypocaloric diet before treatment. Free testosterone was decreased in group B (58.2 ± 9.1) more than group A (73.6 ± 12. 9). Conclusion The results confirm the beneficial effects of metformin in patients with PCOS. It also proves that the addition of low-dose spironolactone induces a more marked reduction of clinical and biochemical hyperandrogenism in patients with PCOS present with hyperandrogenic conditions.
