Selected markers of endothelial dysfunction in women with polycystic ovary syndrome.
Journal Title: Endokrynologia Polska - Year 2011, Vol 62, Issue 3
Abstract
Background: The increased incidence of cardiovascular disease in women with polycystic ovary syndrome (PCOS) has prompted researchers to look for indicators of early atherosclerotic changes in these patients. One of the earliest stages of atherogenesis is endothelial cell dysfunction. The aim of this study was to assess the levels of selected plasma markers of endothelial injury [E-selectin, endothelin-1 (ET-1) and von Willebrand Factor antigen (vWF:Ag)] in PCOS women before and after six months of treatment. Material and methods: 32 patients with PCOS aged 18-36 years (mean age 25.16 ± 5.80) were included in the study. The control group consisted of 20 healthy women matched for age and body mass. The levels of ET-1, vWF:Ag, E-selectin, fasting glucose, insulin, total cholesterol, HDL and LDL-cholesterol and triglycerides were assessed. In the PCOS group, all these tests were repeated after six months of treatment. Results: The study showed higher levels of vWF:Ag (p = 0.043), E selectin (p = 0.028), insulin (p = 0.044), glucose (p = 0.036) and LDL (p = 0.006) in PCOS patients versus healthy women. A positive correlation was demonstrated between E selectin and glucose (p = 0.0001), triglycerides (p = 0.014) and uric acid (p = 0.008). vWF:Ag levels showed a positive correlation with glucose (p = 0.04) and triglycerides (p = 0.036). A positive correlation was also found between ET-1 and total cholesterol levels (p = 0.012) in PCOS women. After treatment, there was a significant reduction in E-selectin levels from baseline (p = 0.002) and an increase in the levels of HDL (p = 0.0002) and triglycerides (p = 0.033). Conclusions: Elevated levels of vWF:Ag and E selectin in PCOS women suggest endothelial dysfunction in this group of patients. Glucose and triglyceride are significant factors affecting endothelial function in PCOS. (Pol J Endocrinol 2011; 62 (3): 243-248).
