ACTA ENDOCRINOLOGICA (BUC)

Introduction. We aimed to investigate Cardiotrophin-1 (CT-1) levels along with other markers of cardiovascular disease and the association of androgen levels with these parameters in both lean and overweight or obese PCOS patients. Material and Methods. The study included 90 overweight or obese PCOS patients with metabolic syndrome (MS) and 80 lean PCOS patients without MS. The control group consisted of 140 healthy females. Anthropometric measurements, plasma glucose, insulin, lipid and hormone profile, homocysteine, hs-CRP, CT-1 levels and carotid-IMT were evaluated in all study subjects. Results. Fasting insulin, HOMA values were significantly higher in obese PCOS patients. Total testosteron levels were higher in both PCOS groups with respect to both controls. Serum homocysteine, hs-CRP, CT-1 and carotid- IMT values were significantly higher in both PCOS groups compared to controls (p=0.001, pCIMT: 0.005). CT-1 was positively correlated with insulin, HOMA, total testosterone, homocysteine, hs-CRP and carotid IMT. After multiple regression analysis, CT-1 was significantly positively correlated with total testosterone, hs-CRP and carotid IMT. Conclusions. CT-1 was associated with other cardiovascular risk markers and its use as a cardiovascular risk marker might be suggested. Cardiovascular risk was increased even in lean PCOS patients without MS and it might be associated with elevated androgen levels.
