The objective: to study the potential otoprotective and antioxidant activity of cytoflavin in new pulmonary tuberculosis patients receiving aminoglycoside amikacin. Subjects and Methods. A randomized controlled trial was conducted and included 90 patients with new infiltrative pulmonary tuberculosis with decay, of both genders aged from 20 to 50 years old. Clinical, paraclinical and statistical methods were used in the study. Audiometric screening was carried out by Diagnostic Audiometer AD 226. The degree of antioxidant protection was determined by the oxidation reaction of ABTS in blood serum and plasma. Results. The study included 4 groups of tuberculosis patients and 1 group of healthy donors. Dissemination of pulmonary tuberculosis in 4 groups was approximately the same and was measured by scores. Prior to the start of treatment in all 4 groups (the group receiving standard chemotherapy (CTX) without amikacin, the group receiving «CTX+amikacin», the group receiving «CTX+cytofl avin», the group receiving «CTX+amikacin+cytofl avin») there was a decrease in blood antioxidant activity compared to Control Group. After 3 months of tuberculosis treatment in all 4 groups, the results improved, while in «CTX+Cytofl avin» Group they were similar to Control Group, and «CTX+Amikacin+Cytofl avin Group», they were only 4.8% less. The elevated level of leukocytes decreased by 10.6% in CTX Group, 16.9% in «CTX+Amikacin» Group, 38.3% in «CTX+Cytofl avin» Group, and 72.3% in «CTX+Amikacin+Cytofl avin» Group. In the study, manifestations of oto- and vestibulotoxicity were found only in the «CTX+Amikacin» Group (in 4/20 (5%)). There were no such cases in «Amikacin+Cytofl avin» Group consisting of 23 patients.

The objective: in an in vitro experiment, we compared phagocytic parameters of mesenchymal stromal cells (MSCs) and macrophages to tuberculous mycobacteria, assessed the ability of MSCs and macrophages to lyse mycobacteria or maintain their intracellular growth, their effect on formation of phenotypic drug resistance of mycobacteria, as well as the effect of tuberculous mycobacteria on the type of MSCs cell death. Subjects and Methods. Balb/c male mice, aged 6 to 8 weeks, were used in the experiment. Bone marrow MSCs were obtained from femurs and tibias by further cultivation, peritoneal macrophages were elicited with 4% alpha-glucan. The intracellular content of mycobacteria was counted using a confocal microscope with x 400 magnification. Susceptibility of mycobacteria to isoniazid and development of phenotypic drug resistance after culturing MSCs and macrophages with MTB on Lowenstein–Jensen medium was assessed by counting CFU. In 5 days after the infection, the number of apoptotic and necrotic MSCs and macrophages was determined by a flow cytometer. Results. On Day 1, the total number of phagocytosed MTB, as well as the number of phagocytic-active macrophages, exceeds the corresponding figures for MSCs more than twice. MSCs phagocytize tuberculous mycobacteria in a smaller amount, but MTB reproduces in them more actively: the number of CFU after 7 days of cell cultivation with MTB exceeded the corresponding parameter by almost 50 times after 24 hours of cultivation. In cultures of infected MSCs cultivated for 7 days, regardless of the presence of isoniazid, there was a rapid growth of tuberculous mycobacteria. On Day 5 after infection of macrophage culture with tuberculous mycobacteria, the number of necrotic cells was 2.7 times greater than that of uninfected necrotic macrophages, but the number of apototic cells in these groups differed slightly. In the culture of MSCs, there were 8.5 times more infected nectrotic cells versus uninfected necrotic MSCs, and the number of necrotic MSCs was 4.5 times higher than the number of MSCs with apoptosis, while in the culture of infected macrophages, the number of necrotic cells was the same as number of apoptotic cells. Unlike macrophages, treatment of MSCs with isoniazid did not inhibit the intracellular proliferation of MTB. Conclusion. MSCs have the ability to phagocytose mycobacteria, but they do it less actively than macrophages and, unlike macrophages, they are not able to restrain the reproduction of tuberculous mycobacteria. Mycobacteria have phenotypic drug resistance in MSCs. In MSCs, when infected with tuberculous mycobacteria, there is a pronounced shift towards necrosis in the type of cell death, which can lead to dissemination of MTB and development of local destructive changes.

The objective: to study the efficacy of antimicrobial photodynamic therapy (APDT) using hydroxyaluminum phthalocyanine (Photosens) as a photosensitizer in the experimental model of tuberculosis infection in mice. Subjects and Methods. Balb/cmice were infected with the multiple drug resistant (MDR) strain of M. tuberculosis Beijing BO/W148. APDT with hydroxyaluminum phthalocyanine and red laser light exposure were started on Day 45. A total of 4 sessions of APDT on the projection of both lungs, liver and spleen were performed. On Day 60, the therapeutic eff ect of APDT was assessed by evaluation of severity of mycobacterial load and specific granulomatous infiltration in the lungs, liver and spleen. The absorption of light energy of laser radiation by the chest and abdominal walls, as well as tissues of lungs, liver and spleen was determined by photometry using afluovisor. Results. The tissues of the experimental animal retain a significant amount of light energy, however, the residual value of light transmission is sufficient to provide a pronounced therapeutic effect which manifests itself as a significant decrease of mycobacterial load and specific inflammatory process in all the studied internal organs. Conclusion. APDT may be an effective tool to treat some forms of tuberculous infection including those caused by M. tuberculosis with MDR.

The objective: analysis of tuberculosis epidemiological rates in children and adolescents in the Siberian Federal District in 2020-2022. Subjects and Methods. Offi cial statistical reporting data (Forms No. 30, 33, 8, and 61) and additional information requested from the regions of the Siberian Federal District were used for analysis. Results. In 2020 in the Siberian Federal District, tuberculosis incidence among children and adolescents aged 0–17 falsely reduced, possibly due to the «deprivation» of the medical care during the COVID-19 pandemic. In 2021 and 2022, the rate increased, there was an increase in the proportion of new patients in the group of 0–14 years old, an increase in the number of cases of secondary tuberculosis which may indicate a deterioration of tuberculosis situation in the District. In 2022, the incidence of extrathoracic tuberculosis increased in adolescents aged 15–17 years. The number of cases of TB/HIV co-infection is growing. There are single lethal cases due to tuberculosis in children in the regions of the Siberian Federal District over the past 5 years, and this rate continues to decline.

The objective: to analyze the quality of phthisiosurgical care in the Siberian and Far Eastern Federal Districts monitored by Novosibirsk Tuberculosis Research Institute (NTRI). Subjects and Methods. Statistical reports for 2019 from phthisiosurgical departments of 17 Russian regions within the Siberian and Far Eastern Federal Districts were analyzed. The reports refl ected the initial period of the pandemic. Results. The analysis of the quality of phthisiosurgical care in the Siberian and Far Eastern Federal Districts covered the areas monitored by Novosibirsk Tuberculosis Research Institute, the Russian Ministry of Health. The main performance rates of phthisiosurgical departments of 17 Russian regions are presented for 2019, they demonstrate a positive trend, and their facilities and resources have signifi cantly improved. The trend towards reduction of phthisiosurgical beds is observed in the regions, which may be due to the service centralization and improved access to surgical and high-tech care in federal institutions. Surgical departments possesses substantial reserves for increasing the number of surgeries, one of which is the revision of cohorts.

The objective : immunohistochemical and electron microscopic imaging of the SARS-CoV-2 coronavirus in lung, lymph nodes and kidney tissues of patients who died of COVID-19. Subjects and Methods . For immunohistochemical tests, specimens of sections of formalin-fixed and paraffin-embedded tissues of the lungs, lymph nodes and kidneys of patients who died from COVID-19 were used. Quantitative assessment of the SARS-CoV-2 viral load level was carried by the original RT qPCR and calculated by the formula: SARS-CoV-2 copy number/ABL1 х 100 copies, expressed as the ratio of the true number of SARS-CoV-2 cDNA copies per 100 copies cDNA of the ABL1 gene. For morphological tests, samples of native lung, lymph node and kidney tissues were taken. Results . Immunohistochemical and electron microscopic tests revealed particles of the SARS-CoV-2 coronavirus in the cytoplasm of endothelial cells of air-blood barrier of the lungs, the vascular glomerulus of the kidneys, in the cytoplasm of macrophages of the lymph node, and also in cytoplasm of lymphocytes in the lumen of lung capillaries.

The optimal parameters of the Alamar Blue test have been determined to detect the antituberculous activity of the chemical compounds under study. The duration of mycobacterial cell incubation before addition of Alamar Blue is 24 hours; that is 17 hours for both H37Ra and H37Rv M. tuberculosis. A method has been devised to evaluate the bactericidal/bacteriostatic activity of the chemical compounds. A thoroughly characterized collection of clinical M. tuberculosis strains that differ in drug sensitivity has been created. A procedure has been developed to reveal the activity of the chemical compounds, by applying mono and multiresistant M. tuberculosis strains. Variability in the growth rate for the clinical strains of mycobacterial cultures is shown. A method has been devised to evaluate the toxicity of the chemical compounds for eukaryotic cells.
