Effect of vitamin E on serum levels of vascular endothelial growth factor and angiopoietin-1 in women with polycystic ovary syndrome: A pilot randomized, placebo-controlled trial

Background: Angiogenesis disturbances are common in women with polycystic ovary syndrome (PCOS). Vitamin E has antiangiogenic properties. Data on the effects of vitamin E on angiogenesis in PCOS are limited, so the study was conducted to evaluate the effects of vitamin E supplementation on angiogenic indices in PCOS patients.Materials and Methods: This randomized, double-blind, placebo-controlled trial was performed on 43 women aged 20–40 years diagnosed with PCOS (Rotterdam criteria). It was performed at the referral clinic affiliated to Tabriz University of Medical Sciences, from April 2017 to September 2017. Patients were randomly assigned into two groups to receive either 400 IU/day vitamin E -as alpha tocopheryl acetate- (n =22) or placebo (n =21) for 8 weeks. Anthropometric, and angiogenic parameters including body weight, fat mass and fat free mass, vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), angiopoietin-1 (Ang-1), and angiopoietin-2 (Ang-2) were measured by standard methods at the beginning and at the end of study. Statistical Package for Social Science version 25 was used for statistical analysis and p values
