Taking into account the data from the World Health Organization on the insufficient level of therapeutic success in the treatment of MDR and XDR pulmonary TB, surgical treatment is necessary in regions with a high frequency of drug-resistant cases.

ВведениеХарактерной особенностью последних десяти-летий является увеличение частоты рецидивов ту-беркулеза как после терапевтического, так и после хирургического лечения [1,2,5,8,13]. Многие хи-рурги связывали это в первую очередь с увеличени-ем частоты лекарственной устойчивости микобак-терий туберкулеза [3,6,20,21].Несмотря на все возрастающую роль хирургии в лечении легочного туберкулеза и ее высокую непо-средственную эффективность, проблема послеопе-рационных рецидивов туберкулеза остается серьез-ным сдерживающим фактором на пути ее широкого применения. Частота послеоперационных рециди-вов, по данным изученной нами литературы, со-ставляет в среднем 5,7% и имеет в последние годы тенденцию к увеличению.

Objectives. The aim of the study was to investigate the cause of death of tuberculosis patients infected with the human immunodeficiency virus (HIV). Many researchers and experts note the urgency of the problem of tuberculosis combined with HIV infection in the world and in Russia. One of the main criteria for assessing the effectiveness of medical care for tuberculosis patients infected with the human immunodeficiency virus is the mortality rate.Materials and methods. For a detailed study of the causes of death of patients with tuberculosis in combination with HIV infection, we analyzed the causes of death of this contingent of patients in 5 regions of the Russian Federation.Results. The social characteristics of patients, the forms and course of the disease, the main and immediate causes of death of 223 patients with co-infection with HIV and tuberculosis were studied.Conclusion. Half of the deaths of tuberculosis patients infected with human im­munodeficiency virus were not associated with tuberculosis. Among these cases, there was either the presence of several infections at the same time, equally leading to death, or separate opportunistic infections (candidiasis, Pneumocystis pneumonia, toxoplasmosis), or cancer. In addition, the lifestyle of patients often became the cause of deaths, namely: drug poisoning and accidents, or cirrhosis of the liver, which develops as a result of alcoholism or hepatitis C infection which occurred during intravenous administration of drugs.

To date, tuberculosis (TB) remains the primary cause of mortality in human immunodeficiency virus (HIV) patients in Russia. Since the beginning of 2000, a sharp change in the HIV patients’ structure, to the main known risk factors for HIV infection has taken place in Russia. The transmission of HIV through injectable drug use has begun to decline significantly, giving way to the prevalence of sexual HIV transmission today. These changes may require adjustments to organizational approaches to anti-TB care and the treatment of HIV-positive patients. Our study is aimed at identifying changes in TB-HIV coinfection patients’ structures in 2019 compared to 2000. Based on the results obtained, our goal was to point out the parameters that need to be taken into account when developing approaches to improve the organization of TB control care for people with HIV infection. We have carried out a cross-sectional, retrospective, epidemiological study using government TB registry data from four regions in two federal districts of Russia in 2019. The case histories of 2265 patients from two regions with high HIV prevalence, which are part of the Siberian Federal District of Russia, and 89 patient histories from two regions of low HIV prevalence, which are part of the Central Federal District of Russia, were analyzed. We found that parenteral transmission (69.4%) remains the primary route of HIV transmission among the TB-HIV coinfected. The unemployed of working age without disability account for 80.2% of all coinfected people, while the formerly incarcerated account for 53.7% and the homeless account for 4.1%. Those with primary multidrug-resistant TB (MDR-TB) comprise 56.2% of HIV-TB patients. When comparing the incidence of coinfection with HIV among TB patients, statistically significant differences were obtained. Thus, the chances of coinfection increased by 4.33 times among people with active TB (95% CI: 2.31; 8.12), by 2.97 times among people with MDR-TB (95% CI: 1.66; 5.32), by 5.2 times in people with advanced processes in the lungs, including destruction, (95% CI: 2.78; 9.7), as well as by 10.3 times in the case of death within the first year after the TB diagnosis (95% CI: 2.99; 35.5). The absence of data for the presence of TB during preventive examination was accompanied by a decrease in the chances of detecting coinfection (OR 0.36; 95% CI: 0.2; 0.64). We have identified the probable causes of the high incidence of TB among HIV-infected: HIV-patient social maladaptation usually results in delayed medical care, leading to TB treatment regimen violations. Furthermore, self-administration of drugs triggers MDR-TB within this group. Healthcare providers should clearly explain to patients the critical importance of immediately seeking medical care when initial TB symptoms appear.
