Differential Impact of Insulin Sensitizers vs. Anti-Androgen on Serum Leptin Levels in Vitamin D Replete PCOS Women: A Six Month Open Labeled Randomized Study

Horm Metab Res 2020; 52: 89-94 DOI: 10.1055/a-1084-5441Women 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...
