Nature of the reaction of the immunocompetent cells in children with nephrotic syndrome and in their parents with different HLA phenotypes

: The purpose of the study was to analyze the character of the expression of the blood lymphocyte epitopes SD4, SD8 (EBLE SD4, SD8) in a series of the loading in-vitro tests in children suffering from the nephrotic syndrome, with different HLA haplotypes. Nine children with the hormone-sensitive nephrotic syndrome (HSNS) and hormone-resistant nephrotic syndrome (HRNS) and 11 parents were examined. Before and after the in-vitro loading with medicamentous agents EBLE SD4, SD8 were determined by flow cytofluorometry, while HLA antigens were tested by the standard micro-lymphocytotoxic method. The studies allowed revealing differences in the responses of EBLE SD8 to the in-vitro loading in children with the HRNS and HSNS. The character of EBLE SD4, SD8 in a child with the NS and its parents may attest to the involvement of those antigens in the pathogenetic component of the given disease.
