[HLA antigens in patients with osteoarticular tuberculosis with different disease course]

Examination included 93 Uzbek patients with osteoarticular tuberculosis: 37 had localized and 56 disseminated tuberculosis process. All the patients were typified according to the HLA antigen locuses-A, B, C and DR by the standardized microlymphocytotoxic test. As a control, 135 healthy Uzbeks were typified by antigens of the same HLA locuses (105 subjects were typified by antigens of the HLA-DR locus). The patients with osteoarticular tuberculosis were found to have genetically controlled susceptibility to tuberculosis infection. The frequency of HLA, B7, B27 and DR2 antigens occurrence in tuberculosis patients is increased as compared to that in healthy subjects. In patients with a disseminated tuberculosis process, the frequency of HLA-Cw4 and HLA-DR4 antigens was increased to 33.9% and 44.6%, respectively, as compared to that in patients with a localized process (5.4% and 21.6%, respectively).
