Epidemic Patterns and Effectiveness of Treatment of Tuberculosis Patients with Different Drug Resistance Profiles in the Republic of Tajikistan

Abstract

The objective: study of the burden and effectiveness of treatment of multiple drug resistant pulmonary tuberculosis (MDR TB) with different chemotherapy regimens in the Republic of Tajikistan.Subjects and Methods. To achieve this objective, the prevalence of drug resistant tuberculosis in 2009–2020 was studied by analyzing statistical documents on drug resistant tuberculosis, official reporting data from the Center for Medical Statistics and Republican TB Control Center by the Ministry of Health and Population Social Welfare of the Republic of Tajikistan.Results. The analysis of official statistics indicates a stable trend towards a decrease in tuberculosis incidence from 2014 to 2019, annually on average up to 1% – from 60,8 to 56,5 per 100,000 population. During the pandemic in 2019–2020, this trend increased, according to statistics the incidence made 39.7 per 100,000 population. From 2014 to 2019, tuberculosis mortality also declined steadily from 3,9 to 2,2 per 100,000 population. During the pandemic in 2019–2020, a rapid decline was noted – from 2,2 to 1,4, while in 2020–2022, it decreased from 1,4 to 1,0 per 100,000 population. From 2013 to 2020 treatment success reached 90%. The detection of drug resistant tuberculosis is close to 900 cases per year, and more than 90% of them were covered with treatment. In 2018–2020, successful treatment of drug resistant tuberculosis increased from 72,5% to 80,6% due to the introduction of new and repurposed anti-tuberculosis drugs.
