Abstract

Women with PCOS are linked to insulin resistance, inflammation, and vitamin D (VD) deficiency. The study endeavors to comprehend the differential impact of insulin sensitizers vs. anti-androgen on serum leptin levels among women with PCOS rendered vitamin D replete with high VD oral supplement. This was open-labeled randomized study that screened 180 eligible women presenting to Endocrine clinic with oligomenorrhea or features of hyperandrogenism. Ninety-nine women who furnished written informed consent and fulfilled the Rotterdam 2003 criteria for diagnosis of PCOS were randomized into 3 drug treatment arms to receive either spironolactone (50 mg/d; n=30), metformin (1000 mg/d; n=30) or pioglitazone (30 mg/d; n=30). These women were also administered oral VD (4000 IU/day) in addition to the allocated drug for a period of 6 months. Detailed history, clinical examination, and laboratory evaluation was carried out at baseline and 6 months after intervention. Number of menstrual cycles/year increased while as Ferriman–Gallwey score, blood glucose, HOMA-IR, and plasma insulin levels significantly decreased in all the three arms with better outcomes in spironolactone and pioglitazone arms (p<0.05). Similarly, serum leptin levels superiorly improved in spironolactone and pioglitazone group. Pioglitazone group showed better efficacy in lowering serum total testosterone (p<0.05). Co-supplementation of high dosage VD with spironolactone or pioglitazone are more effective in reducing plasma leptin levels than metformin, and thus might prove to be better therapeutic strategies for women with PCOS.
