[Differential approach to lymphadenectomy in patients with progressive fibrocavernous pulmonary tuberculosis].

The resection specimens from 31 patients with fibrocavernous tuberculosis (FCT) underwent a complex clinical andimmunological study, as well as a morphological one. It was ascertained that partial or extended lymphadenectomy did not always positively correlate with an adequate postoperative immune response and it depended on the morphological features of lymphatic apparatus lesion. The direct results of surgical treatment of patients with FCT suggest that in patients with specific lymphadenitis and cell-mediated immunodeficiency, the frequency of postoperative specific pleuropulmonary complications and their severity considerably exceed those if there is an adequate immune response.

[Immunogenetic aspects of the course and treatment of pulmonary tuberculosis].

The paper presents the clinical, X-ray, and laboratory characteristics of patients with pulmonary tuberculosis. Both general regularities and differences in the frequency of alleles of the HLA-DQB1* locus have been revealed in the groups of patients with pulmonary tuberculosis as compared with healthy individuals. There are specificities associated with the risk of pulmonary tuberculosis and the variants of the course of infection; thus, allele 05 of the HLA-DQB1* locus is positively associated with the incidence of tuberculosis.

[Some regularities of an immune response in patients with pulmonary tuberculosis and drug-resistant Mycobacterium strains].

Clinical and immunological studies were conducted in 62 patients with infiltrative pulmonary tuberculosis and 53 with disseminated one. As drug resistance and viability of mycobacteria increased, an immune response was found to develop as the humoral type and cellular immunity was suppressed. A more marked reduction in the activity of T helper cells type 1 of an immune response and the neutrophilic granulocytic system was revealed in patients with disseminated pulmonary tuberculosis.

[Immunological parameters and mycobacterial biological properties in infiltrative pulmonary tuberculosis].

Thirty-one patients with infiltrative pulmonary tuberculosis were clinically and immunologically examined. A relationship was found between the definite immunological parameters and the biological properties of mycobacteria. The higher viability of mycobacteria and the increase in the drug resistance have been shown to be associated with the decreased activity of lymphocytes and the suppressed production of interleukin-2, which suggests a decrease in the activity of type 1 T helper cells and a significant increase in the synthesis of tuberculosis antibodies with the lower serum concentrations of circulating immune complexes.

[Parameters of acquired immunity and cation proteins of neutrophilic granulocytes in pulmonary tuberculosis].

Clinical and immunological studies of 61 patients with pulmonary tuberculosis have indicated that the status of acquired and congenital (natural) immunity assessed by the intra- and extracellular levels of cation proteins of neutrophilic granulocytes is different in different clinical forms of pulmonary tuberculosis. The found correlations suggest that there is a relationship between the factors of acquired and congenital immunity and that cytokines are involved in the regulation of specific inflammation. More active degranulation of azurophilic granules of neutrophils occurs due to myeloperoxidase.
