[Population-based epidemiological study of pulmonary tuberculosis in a number of rural regions of Tatarstan].
The paper presents the results of a population-based, geneticoepidemiological, and immunological study conducted in two regions of Tatarstan. The population-based risks for tuberculosis were established for males and females. Based on the population and family data, the authors calculated the genetic liability to tuberculosis, namely hereditability that is in the range of 0.8 to 1.0 and includes the contribution of nongenetic and environmental factors. Analysis of the results of immunogenetic studies of the northwestern region of Tatarstan has ascertained that patients have an association with the HLA antigen B22, in the Kama Region there is an association with other HLA antigens: B12 and B16. The higher frequency of the HLA antigens B28 and CW1 in healthy individuals as compared with that in patients with pulmonary tuberculosis (PT) suggests the resistance of PT carriers of these antigens for the disease. A study of the distribution of HLA genes by polymerase chain reaction has established the association of the disease with the DR-B1-15 genes in the Kama Region.
