        Association of serum levels of vascular endothelial growth factor and thrombospondin-1 to body mass index in polycystic ovary syndrome: a case-control study

        PurposePolycystic ovary syndrome (PCOS) is a gynecological endocrine disorder that is characterized by disturbances in ovarianblood flow and angiogenesis. The aim of this study was to determine the association of vascular endothelial growthfactor (VEGF) and thrombospondin-1 (TSP-1) serum levels with the body mass index (BMI) in patients with PCOScompared with healthy subjects. MethodsThe study was conducted with 80 subjects in 3 PCOS groups, including normal weight, overweight, and obese PCOSgroups, and a control group of healthy subjects (n=20). The participants in all groups completed a questionnairecomprising sociodemographic and obstetric questions. The PCOS diagnosis in the study subjects was confirmed basedon the Rotterdam criteria, BMI was determined according to the World Health Organization guidelines, and the lipidaccumulation product index was calculated for all groups. Venous blood samples were collected from all participantsafter fasting to measure the serum levels of fasting blood glucose (FBG), lipids, insulin, VEGF, TSP-1, and leptin. ResultsOur findings showed that the serum VEGF level was significantly higher in the normal BMI PCOS group than thatin the control group (P=0.03), and the TSP-1 level was significantly lower in the obese PCOS group than that in thecontrol group (P=0.04). ConclusionsOur study demonstrated that alterations in VEGF and TSP-1 concentrations are dependent on BMI. Because abnormalovarian angiogenesis is considered to be the main feature of PCOS, the study of ovarian angiogenic imbalance isproposed as a new tool for PCOS diagnosis and management.
