摘要
To investigate oxidative stress and angiogenetic factors in polycystic ovary syndrome (PCOS).Prospective cohort study.University outpatient clinic.Fifty women with PCOS were divided into two groups: body mass index (BMI) >27 kg/m(2) (n = 25) and BMI <27 kg/m(2) (n = 25). The control group consisted of 20 age- and BMI-matched healthy women.None.Enzyme-linked immunosorbent assays were used to measure serum levels of 8-hydroxydeoxyguanosine (8-OHdG), angiopoietin-2, and vascular endothelial growth factor (VEGF).Women with PCOS had significantly lower serum 8-OHdG levels (mean 137.8 pg/mL, range 53.4-282.9 pg/mL) compared with the control subjects (mean 219.78 pg/mL, 124.6-372.4 pg/mL). This difference was obvious in both lean (BMI <27 kg/m(2)) and obese (BMI >27 kg/m(2)) subjects. Concentrations of VEGF were higher among obese subjects with PCOS.Serum 8-OHdG levels are significantly lower in women with PCOS than in healthy controls. The clinical significance of this finding is discussed.
