    Streszczenie angielskie: Background: Female are characterized by significantly higher plasma leptin concentration than males. It seems likely that sex hormones influence leptinemia independently from differences in body composition. The aim of the present study was to analyze the contribution of plasma concentrations of testosterone and estradiol on leptinemia in hemodialyzed patients. Methods: 110 hemodialyzed patient - HD (60 M. 50 F) and 70 healthy subjects (HS) (30 M, 40 F) were enrolled in this study. Plasma leptin, testosterone or estradiol and CRP concentrations and body composition by dual-energy X-ray absorptiometry (DEXA) were assessed. Results: Total body fat was significantly higher in femals than in males (27.5 ń 1.5 p.c. vs. 17.2 ń 1.0 p.c. of body weight in HD and 36.0 ń 1.0 p.c. vs. 18.2 ń 1.4 p.c. in HS, respectively). Plasma leptin concentrations were markedly higher in females than in mals both in HD (27.9 ń 5.4 ng/ml vs. 9.6 ń 1.9 ng/ml) and HS (16.5 ń 1.7 ng/ml vs. 3.1 ń 0.4 ng/ml). A highly significant, strong positive correlation was found between total fat mass (TFM) and leptinemia in all studied groups. No significant univaried correlation between plasma leptin and testosterone or estradiol concentrations respectively was found both in HD and HS. Multiple regerssion analyses showed that the main determinant of leptinemia is TFM (á = 0.623 and 0.798 in HS females and males respectively, and á = 1.058 and 0.797 in HD females and males respectively). Plasma concentration of testosterone (á = -0.139 and á = - 0.075 in male HD and HS respectively)...
