[Clinical and immunological features of concomitant HIV/tuberculosis infection and HIV infection without tuberculosis].

The clinical and hematological manifestations and functional state of the immune system were comparatively evaluated in patients with concomitant HIV/tuberculosis (TB) infection (n = 84) and in those with HIV infection without tuberculosis (n = 106). The course of concomitant HIV-TB infection was ascertained to differ from HIV monoinfection in a diversity of additional exposures that aggravated the patients' general condition. These included: the parameters of a long proceeding inflammatory process, which were accompanied by the signs of the infection-toxic syndrome, inflammatory changes in the hemogram, by a sharp stimulation of the nonspecific link of immunity. So the comparative analysis of the trend in HIV infection in combination with active tuberculosis and HIV monoinfection revealed a prompter progression of the disease in the former case.

[Pathomorphism of pulmonary tuberculosis under the present conditions (according to autopsy data)].

Intraoperative (n = 290) and autoptic (n = 246) materials obtained from tuberculosis hospitals in 2005-2007 were examined to study the pathomorphism of pulmonary tuberculosis. The study revealed an increase in the number of patients with acute pulmonary tuberculosis. Fibrocavernous tuberculosis halved as compared to the 1980s. Incapsulated pulmonary tuberculosis is prevalent in the phthisiosurgical material (more than 70% of cases). The leading cause of pulmonary tuberculosis was progression of a specific inflammatory process while cardiopulmonary failure and visceral amyloidosis became rare causes of death. The higher incidence of poorly progressive pulmonary tuberculosis in males (they accounted for 85% of the number of death cases) was associated with concomitant and aggravating diseases, such as alcoholism, drug addiction, and HIV infection (68.5% of cases).

[The specific features of formation of a humoral immune response in patients with tuberculosis].

The paper presents the results of studying the time course of changes in tuberculosis antibodies by enzyme immunoassay (EIA) and immune blotting (IB) in 34 patients with pulmonary tuberculosis. In 76.5% of cases, EIA were established to reveal tuberculosis antibodies whose concentration is most pronounced in lung tissue destruction. The detection rate of specific antibodies to Mycobacterium tuberculosis (MBT) structural components by IB was 100%, which was 23.6% greater than that by EIA. The MBT structural components with a molecular weight of 11-20, 21-30, and 101-160 kDa were found to have high immunogenic properties, as suggested by the maximum levels of antibodies and by the marked antigenic proteins of proteins with a molecular weight of 11-20, 21-30, and 41-50 kDa, which showed itself as the generation of the maximum levels of circulating immune complexes with antigens of this specificity.

[Clinical and immunological features of the course of tuberculosis concurrent with HIV infection].

The clinical and immunological features of the course of tuberculosis concurrent with HIV infection were studied in 109 patients. Thirty-eight patients were found to have active tuberculosis to HIV infection; 22 patients were diagnosed to have HIV infection and tuberculosis, and 49 patients developed tuberculosis in the presence of HIV infection. The most acute course of the disease with severe infection-toxic and asthenovegetative syndromes was observed in patients with simultaneous detection of HIV infection and tuberculosis, and, when tuberculosis joins as a secondary disease in the presence of HIV infection, the bronchopulmonary syndrome, body weight loss, lymphoadenopathy, and skin lesion were pronounced at most. The most severe clinical forms of tuberculosis were observed in a group where tuberculosis manifested itself as an opportunistic disease in the presence of moderate and severe immunodeficiency.

[Distribution of HLA antigens in patients with tuberculosis and healthy individuals in the Tatar population]. / Raspredelenie antigenov kompleksa HLA u bol'nykh tuberkulezom i zdorovykh lits v Tatarskoi populiatsii.

The paper presents the results of a study of the distribution of Class I HLA antigens in an ethnic Tatar group (in patients with pulmonary tuberculosis and healthy individuals) in 4 districts of Tatarstan. It has been ascertained that an association with HLA-B22 antigen exists in patients with active pulmonary tuberculosis.
