title: [Membrane markers of T- and B-lymphocytes in children with primary immunologic deficiency conditions].
abstract: Altogether 79 children with primary immunodeficiency conditions (PIC) and 21 children suffering from frequently occurring bacterial infections were examined for the level of rosette-forming cells and lymphocytes reacting positively with monoclonal antibodies to different phenotypic membranous markers (SD-antigens and others). The patients with combined forms of immunodeficiency, with T deficiency playing the key role manifested a significant lowering of the content of the subpopulations of SD3+, SD5+, SD7+ and SD4+ lymphocytes and the decrease of the SD4/SD8 ratio. The the reduction of the number of B lymphocytes (smIg + K1, SD19 +), the low levels of Ia+ -cells, and the decrease of the SD4/SD8 at the expense of the content of SD8+ -cells. In the patients with selective immunodeficiency and recurrent bacterial infections without verified PIC, these parameters did not undergo any essential changes. As compared with immunofluorescent assays, the measurement of E-RFL and M-RFL amounts was found to have insufficient information content for the diagnosis of PIC.
