[Genetic conditions of synthesis of selected cytokines in children with nephrotic syndrome].

In this study a genetic determination of some cytokines synthesis is presented in group of 23 children with various kinds of nephrotic syndrome (NS). The gene polymorphisms of TNF-alpha, TGF-beta, IL-6, IL-10, INF-gamma were identified using PCR-SSP method combined with the measurement of levels of TNF-alpha, TGF-beta, IL-6, IL-10, INF-gamma synthesis. The differences in occurring frequency of high, middle and low genotypes TNF-alpha, TGF-beta and IL-6 synthesis between children with NS and control group were revealed. Significantly more frequently high TGF-beta and high IL-6 synthesis genotype in NS group were found. Because of high variability of cytokine level in blood in duration of NS and methodic difficulties of their measurement, identification of cytokines genes polymorphisms seems to be a method that can objectively describe the cytokine participation in NS pathophysiology.
