Introduction: Previous studies have examined the correlation between hyperandrogenemia and non-alcoholic fatty liver disease (NAFLD) in women and showed contradictory results. Therefore, we aimed to evaluate the relationship between testosterone level and Fatty Liver Index (FLI), as a surrogate marker for NAFLD, in a cohort of postmenopausal women. Material and methods: A total of 150 postmenopausal women were included in this cross-sectional study. Anthropometric and biochemical parameters, as well as blood pressure, were obtained. Non-alcoholic fatty liver disease is assessed by FLI, an algorithm based on body mass index, waist circumference, triglycerides and γ-glutamyl transferase, as a simple and accurate predictor of hepatic steatosis. Women were divided into three groups (FLI < 30, n = 80; 30 ≤ FLI < 60, n = 44; FLI ≥ 60, n = 26). Homeostasis model assessment of insulin resistance (HOMA-IR) as a surrogate marker of insulin resistance was calculated. Results: Multiple linear regression analysis revealed that the best model consisted of 4 parameters (e.g., bioavailable testosterone (β = 0.288, p = 0.001), log HOMA-IR (β = 0.227, p = 0.005), log high-sensitivity C-reactive protein (β = 0.322, p < 0.001), and retinol-binding protein 4 (β = 0.226, p < 0.001)). Adjusted R2 for the best model was 0.550, which means that as much as 55.0% of variation in FLI could be explained with this model. Conclusions: Bioavailable testosterone is independently associated with FLI in postmenopausal women. © 2016 Termedia & Banach.

Purpose: We investigated the role of serum uric acid (sUA) and superoxide dismutase (SOD) as predictive factors for mortality in hemodialysis (HD) patients. Methods: SOD, butyrylcholinesterase, and malondialdehyde were estimated spectrophotometrically and the other parameters by standard procedures. High-sensitive C-reactive protein was assayed by a sandwich ELISA method. Results: sUA among survivors (112.1 ± 13.82 μmol/L) was significantly lower than in deceased (160.8 ± 16.81 μmol/L, p < 0.001), while SOD was higher in survivors (31.8 ± 6.61 kU/L) than among deceased (20.2 ± 3.03, p < 0.05). Kaplan-Meier survival curves showed the greatest mortality risk in the highest tertile of basal sUA concentration (≥127.11 μmol/L, p < 0.001), and for SOD in the lowest tertile (≤23.83 kU/L, p < 0.05). Conclusion: Our results suggest that high sUA and low SOD may predict all-cause and cardiovascular mortality in HD patients. © 2012 Springer Science+Business Media, B.V.
