Glypican-4 (Gpc-4) is novel adipokine interact with insulin receptor and affects insulin sensitivity in proteoglycans. Gpc-4 serum levels show gender differences; females having higher levels than men, what can suggest mediation by sex hormones. We investigated serum Gpc-4 levels and its association with cardiovascular risk predictors in women (2035 years old) with PCOS (n=62) and healthy control (n=43) presented different sex hormones profile. The following CVD risk predictors: BMI, waist circumference (WC), total fat (TF), androidal fat deposit (AFD), gynoidal fat deposit (GFD), AFD/GFD ratio (A/G), fasting serum glucose, insulin, HOMA, serum triglycerides, total cholesterol, HDL-cholesterol, LDL-cholesterol) and hormonal profile LH, testosterone, androstenedione (Adione), SHBG, Free Androgens Index (FAI) were estimated. Gpc-4 was determined by commercial ELISA kit. Serum Gpc-4 levels in women with PCOS was statistically significant higher than in control group (2.61±1.17 vs 1.55±0.47 ng/ml). Serum Gpc-4 concentration positively correlated with BMI in both groups (P<0.001), but with WC (P<0.001), WHR (P=0.005), TF (P<0.001), AFD (P<0.001), GFD (P=0.008), A/G (P=0.002) only in PCOS group. Serum Gpc-4 concentration were correlated positively with fasting serum insulin and HOMA in PCOS women and in control group (for both and in each group P<0.001). We showed that Gpc-4 concentration positively statistically significant correlated with serum Adione and FAI levels in control group and we observed only the tendency in PCOS group (P=0.054) also with serum LH (P=0.071). This original observation give new light on the role of Gpc-4 in women health, but because of some limitations further study is require.
