Peculiarities of roentgenological picture of pulmonary tuberculosis upon HLA-DRB1 gene polymorphism depending on pro-and-antiinflammatory cytokines concentration

Aim. To study the peculiar features of roentgenological picture of pulmonary tuberculosis in patients with polymorphous HLA-DRB1 allels in the genotype in associations with pro-and-antiinflammatory cytokines concentration.

Materials and methods. The complex clinicoimmunogenetic examination of 64 patients with pulmonary tuberculosis was carried out. The patients’ age ranged 18 to 52 years. The gene HLA-DRB1 polymorphism was determined using the method of polymerase chain reaction with DNA, previously extracted from blood samples. Cytokine concentration was determined in the peripheral blood before specific treatment, using the assay kits of “Vector-BEST Company” (Russia).

Results. The prevailing clinical form of pulmonary tuberculosis among patients was infiltrative one – 40 (62.5). Bacterioexcretion was stated in 89.5 % of cases. Roentgenological picture of pulmonary tuberculosis in patients with HLA-DRB1 *04, *13, *14, *16 alleles was characterized as disseminated injury of lung tissue with destructive changes, the concentration of IL-1b, TNF-α exceeded the standard values by more than 3 times (r = 0.88; р = 0.040), IL-2, IL-10, g-INF was lower than standard values by more than 4–5 times (r = 0.75; р = 0.003).

Conclusions. When studying HLA-DRB1 gene polymorphism and pro-and-antiinflammatory cytokines concentrations in patients with pulmonary tuberculosis, it was established that patients with HLA-DRB1 *01, *07, *08, *10, *15 alleles more often, compared to the others, had disseminated injury of lung tissue, in most cases with its destruction as well as dysbalanced cytokine balance in the direction of deep immunosuppression.
