| Popis: | Introduction: The aim was to assess associations among PCOS and NAFLD, the lipoprotein lipase polymorphism gene, and metabolic disorders in PCOS. Material and methods: In 184 women with PCOS and 125 healthy, premenopausal volunteers, sex steroids, lipids, glucose, insulin, aminotransferases, free androgen index (FAI), HOMA-IR and E2/T were calculated. Hepatic steatosis was determined by ultrasound. Whole genomic DNA was isolated from blood leucocytes. Lipoprotein lipase polymorphisms rs268 and rs328 were analysed by polymerase chain reaction (PCR) and minisequencing. Results: 57.6% of PCOS women had NAFLD, while women without PCOS had NAFLD in 49.6%. PCOS-NAFLD women had higher BMI, WHR and waist circumference compared to women with PCOS without NAFLD and women without PCOS. PCOS-NAFLD women had lower SHBG, E2/T ratio, and higher FAI compared to other groups. ALT levels were higher in PCOS women with NAFLD compared to other groups. PCOS women with and without NAFLD had higher fasting glucose and insulin and HOMA compared to women without PCOS. Women with PCOS had higher triglycerides and lower HDL-C compared to women without PCOS. There was no evidence that evaluated polymorphisms influenced hepatic steatosis in women with and without PCOS. Conclusions: PCOS is not an independent factor influencing NAFLD in women. The influences on NAFLD incidence in women are BMI > 25 kg/m², glucose level > 80 mg/dL, E2/T 19 IU/L as independent factors. Hyperandrogenism in PCOS may increase the risk of NAFLD indirectly by obesity, insulin resistance, and directly by the hepatotoxic effect. Polymorphisms rs328 and rs268 of the lipoprotein lipase gene do not affect the occurrence of NAFLD in women with PCOS or without PCOS. (Endokrynol Pol 2014; 65 (6): 416–421) |
