DESCRIPTION OF ARTICLE: | Submitted as of 25.02.2019 Experimental animal models of tuberculosis (TB) have played a major role in advancing our understanding of the host-pathogen relationship and have provided essential pre-clinical data on the efficacy of new TB drugs and vaccines. For more than 50 years, the guinea pig infected with very small numbers of virulent mycobacteria by the respiratory route has been recognized as a highly biologically relevant model of human pulmonary TB. In this review, the development and application of a guinea pig model to studies of TB pathogenesis and vaccine-induced resistance in the author’s laboratory is discussed. The characteristics of a “rational” TB model and the features of a respiratory exposure system that implants a few tubercle bacilli as droplet nuclei directly into the alveolar spaces are reviewed. The development of immunological tools, including recombinant guinea pig cytokines and antibodies to those cytokines, has facilitated the evaluation of the role of those host proteins in ex vivo cultures of infected macrophages from various anatomical sources. Laser capture microdissection has revealed the cytokine profiles of primary and secondary granulomas in the lungs of naïve and vaccinated guinea pigs exposed to virulent mycobacteria. Chronic, moderate protein deficiency exerted a deleterious effect on host resistance and blunted the protective effect of BCG vaccine, a finding that has relevance for vaccination of malnourished populations. Tumor necrosis factor-alpha (TNF-α) was found to have both positive and negative effects on the host-pathogen interaction. Guinea pig neutrophils were observed to promote the control of virulent mycobacteria by macrophages that ingested apoptotic, infected neutrophils. Taken together, more than 5 decades of research with this model have revealed several novel features of tuberculosis pathogenesis. Most importantly, the availability of the sequenced and partially-annotated guinea pig genome and the development of additional reagents and methodologies have positioned the guinea pig model to continue to make critical contributions to the understanding of TB pathogenesis in the future. |

DESCRIPTION OF ARTICLE: | Submitted as of: 4.02.2019 The investigation of the lung somatic cell resistance to antibiotics, TB drugs in particular, is in the initial stage, opening a new scientific field for TB researchers. The mechanisms of multi-drug resistance of the macroorganism’s somatic cells are realized via special transporter proteins, which transport chemicals (drugs) away from the cell. P-glycoprotein (Pgp) is the most universal of all these proteins, encoded by MDR1 gene in human cells and Mdr1a or Mdr1b gene in murine cells. The objective of our study was to evaluate the influence of progressive TB inflammation on expression of Mdr1a/b genes in the lung cells of mice infected with M. tuberculosis (MTB). Histological description of TB inflammation performed 21, 45 and 90 days after infecting the Balb/c-line mice with MTB showed TB progression. The comparison of the median values demonstrated that during development of TB inflammation expression of Mdr1a genes increased 2.8 times on the 21st day, and 3.5 times – on the 90th day of the experiment. The expression of Mdr1b genes almost twice increased by the 45th day of the experiment as compared to the control group and remained on the same level during the further progression of TB. Thus, we established that the expression of Mdr1a and Mdr1b genes in the lung cells reliably increased during TB progression in the untreated mice. The obtained data witnessed that the factors of TB inflammation development played the role of the gene expression inducer. It is necessary to continue researches in this new scientific field. We suggest that the induction of MDR1 gene expression and the increase of Pgp activity in the lung cells under continuous administration of some TB drugs might be one of the causes of low chemotherapy effectiveness in patients with progressive destructive TB. *The research was performed under research topic no. 0515-2019-0015 “The development of mycobacteria and somatic cells drug resistance to TB drugs” and supported by the Russian Science Foundation grant no. 14-50-00029. |

DESCRIPTION OF ARTICLE: | Submitted as of: 21.02.2019 We studied social status, clinical and radiological manifestations, microbiological and immunological peculiarities in 26 late-stage HIV infection patients with pulmonary TB and concomitant pulmonary mycobacteriosis. They all had CD4+ lymphocyte counts less than 30 cells/μL of blood, did not receive antiretroviral therapy (ART), and excreted both M. tuberculosis and nontuberculous mycobacteria (NTM). We found M. avium complex in 84.6%, M. kansasii – in 7.7%, M. fortuitum – in 3.8% and M. xenopi – in 3.8% of the patients. The disease manifested 6-9 years after diagnosing HIV infection; it had pronounced intoxication syndrome, bronchopulmonary and extrapulmonary presentations and was accompanied by other opportunistic infections. Radiological studies revealed dissemination with predominant localization in the middle and lower lung departments, small infiltrates with cavities, and injury of interlobar and visceral pleura. We proposed a diagnostic algorithm to detect disseminated pulmonary TB, pulmonary mycobacterioses, and other opportunistic infections in immunosuppressed patients with late-stage HIV infection. *The research was conducted under scientific theme 0515-2019-0015 “Modern approaches to diagnosis, epidemiology and treatment of drug resistant pulmonary TB, including TB associated with HIV infection or diabetes mellitus”. |

DESCRIPTION OF ARTICLE: | Submitted as of 12.02.2019 Objective: To study effects of the national tobacco control policy on the prevalence of tobacco consumption and passive smoking among different groups of the population in the Russian Federation in 2004-2016. Materials and methods. The research was based on the data from the national representative studies: the Global Youth Tobacco Survey (GYTS) involving young people aged 13-15 conducted in 2004 and 2015, and the Global Adult Tobacco Survey (GATS) conducted in 2009 and 2016. The both studies used the international validated questionnaires, which included questions about the main measures of the WHO Framework Convention on Tobacco Control (WHO FCTC), implemented through Federal Law no. 15-FZ on Protecting the Health of Citizens from the Effects of Second-hand Tobacco Smoke and the Consequences of Tobacco Consumption, as well as other legislative acts under the national tobacco control policy. Results. Due to the national tobacco control policy, the prevalence of tobacco consumption decreased among adults from 39.4% in 2009 to 30.9% in 2016, and among young people aged 13-15 – from 27.3% in 2004 to 15.1% in 2015. The similar dynamics was observed for passive smoking, which decreased among teenagers from 77.9% in 2004 to 35.0% in 2015. As for adults, essential decrease of passive smoking was observed in all public indoor areas. For instance, in workplaces the relative decline was 33.4%, in dwelling houses – 37.3%. Conclusion. The implementation of the national tobacco control policy, after Russia joined the WHO FCTC in 2008, has resulted in essential decrease in the prevalence of tobacco consumption and passive smoking among the whole population of the Russian Federation. *The research was conducted under scientific theme no. 0515-2019-0020 “Modern approaches to diagnosis, epidemiology and management of drug resistant pulmonary TB, including HIV-associated or diabetes mellitus associated TB”. |

DESCRIPTION OF ARTICLE: | Submitted as of 24.12.2018 First-line TB drugs have a pronounced toxic effect. The changes in the structural and functional state of the peripheral blood mononuclears’ membranes at the end of the intensive phase of etiotropic treatment may serve as an important marker of the changes in immunological reactions of TB patients. We studied 184 patients with focal or infiltrative pulmonary TB on inpatient treatment at Tver Clinical TB Dispensary. Before and after the intensive phase of TB treatment we determined the following phospholipid fractions in the patients’ blood: total lysophospholipids, sphingomyelin, phosphatidylinositol, phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine. We established that first-line TB drugs contributed to disorganization of lipid membranes of immunocompetent cells, accumulation of membrane-destructive lysophospholipids in mononuclear leukocytes, and simultaneously reduced levels of phosphatidylcholine. |

DESCRIPTION OF ARTICLE: | Submitted as of 23.01.2019 The purpose of this study was to evaluate clinical efficacy of wobenzym in the complex treatment of destructive infiltrative pulmonary TB and occurrence of wobenzym-induced toxic reactions. Materials and methods: We studied 60 patients with destructive infiltrative pulmonary TB sensitive to TB drugs. They were divided in two groups. The main group received wobenzym (one tablet twice a day) plus TB drugs. The control group received standard TB treatment. All the patients underwent clinical and laboratory examinations, as well as studies of immune and cytokine statuses: the immunoregulatory index, levels of circulating immune complexes (CICs), the phagocytosis stimulation coefficient, levels of interleukin-2 (IL-2), IL-4, IL-6, interferon gamma (IFNγ), tumor necrosis factor-α (TNF-α), free radical oxidation. Control studies were performed after 4 months. Results. The comparative analysis of treatment efficacy revealed that positive dynamics of clinical symptoms (general weakness, fever, cough, expectoration, chest pain, hemoptysis), reduced intensity of infiltration, cavity closure, sputum negativation were more pronounced in the main group versus the control. Administration of wobenzym in the complex treatment resulted in more significant improvement of immune and cytokine statuses and free radical oxidation, as well as decreased occurrence of hepatotoxic reactions to TB drugs, which allowed uninterrupted treatment. Conclusion. Administration of systemic enzymotherapy as a pathogenetic therapy in the complex treatment of destructive infiltrative pulmonary TB demonstrated essential positive dynamics of clinical and laboratory signs, better resolution of infiltrates, cavity closure, sputum negativation, decreased occurrence and lower severity of toxic reactions, which allowed uninterrupted treatment. |

DESCRIPTION OF ARTICLE: | Submitted as of 02.02.2019 We studied 54 women with pulmonary TB at the stage of TB treatment selection and during subsequent 40-150 days of treatment. We collected their records: physical examinations; data on X-ray and CT studies, bronchological studies, external respiration function tests; clinical, hemostasiological, biochemical blood tests; ultrasound studies of the pelvic organs; cytological studies of vaginal smears; microbiological and molecular-genetic studies of sputum for MTB detection and MTB DNA extraction. A special study of the vaginal microbiota was conducted using the novel test system ”Femoflor” (manufactured by LLC “NPO DNA-Technology”, Russia) with real-time PCR detection and quantitative description of 28 opportunistic microorganisms. After 40-150 days of TB treatment we established a reliable decline of the major normocenosis indicator – Lactobacillus spp., from 66.2% to 15.2% or 9.3% (р ≤ 0.001). On the contrary, the share of opportunistic microflora reliably increased, from 33.8% to 84,8% or 90.7% (р ≤ 0.05). The most indicative were Gardnerella vaginalis and Candida spp. The analysis of the vaginal microbiota species demonstrated gradual transition from normocenosis to moderate aerobic and anaerobic dysbiosis as treatment continued. *The research was conducted under scientific theme 0515-2019-0019 “A multidisciplinary approach to diagnosis, differential diagnosis of TB and other pulmonary diseases in the present conditions”. |

DESCRIPTION OF ARTICLE: | Submitted as of 1.02.2019 Aim: To study consequences of endobronchial valve blockage for the pulmonary ventilation function and detect factors influencing changes in the functional indicators in destructive pulmonary TB patients. Materials and methods. The research involved 88 patients with destructive pulmonary TB. We studied the functional state of the lung in dynamics while performing local artificial collapse after the endobronchial valve placement. We evaluated changes in the spirometric functional indicators. Results. Endobronchial valve blockage led to significant worsening of the pulmonary ventilation function in only 36% of patients. It was due to reduced lung vital capacity or deteriorated bronchial permeability. The frequency and expressiveness of pulmonary ventilation reduction were inversely proportional to the baseline forced vital capacity (FVC) and forced expiratory volume in one second (FEV1); they did not depend on patients’ age, TB dissemination process, an anatomical site of the endobronchial valve placement or volume of “turned off” lung tissue. Conclusion. Endobronchial valve blockage led to significant reduction of the pulmonary function in only one third of patients, and baseline functional disturbances did not increase the risk of such reduction. *The research was conducted under scientific theme 0515-2019-0015 “Modern approaches to the diagnosis, epidemiology and treatment of drug-resistant respiratory tuberculosis associated with HIV-infection and diabetes mellitus”. |

DESCRIPTION OF ARTICLE: | Submitted as of 16.01.2019
The aim of the study: To optimize diagnosis of different types of hypersensitivity pneumonitis (HP) by establishing the most significant clinical and laboratory indicators of blood and bronchoalveolar washings (BAW). Materials and methods. The study enrolled 107 patients with diagnosed HP. We analyzed clinical, X-ray, functional and laboratory indicators of venous blood and BAW, determined the subpopulational composition of lymphocytes using flow cytofluorometry. Results. Clinical and X-ray changes in the lungs in acute and subacute types of HP correlate with high lymphocytic content in BAW, but there is a double difference in the CD4/CD8 ratios. In chronic HP we observe the lowest rates as compared to the norm. The lymphocytic subpopulational composition in the venous blood from HP patients corresponds to the disease type and can be used as an independent laboratory indicator: the CD4/CD8 ratio is elevated in acute HP, decreased – in chronic HP, and normal – in subacute HP. *The research was conducted under scientific theme 0515-2019-0019 “Multidisciplinary approach to diagnosis, differential diagnosis of tuberculosis and other respiratory diseases in modern conditions” |
