A total of 425 patients with respiratory TB were enrolled in this study. They were registered at phthisiatric facilities in the Omsk region from March 2015 to June 2017 period and included: males — 73.1%, mean age 39.9 years, females — 26.9%, mean age 42.0 years. M. tuberculosis culture and drug susceptibility testing and DNA extraction were performed in accordance with standard methods. Strains were assigned to the M. tuberculosis Beijing genotype and its epidemiologically relevant clusters B0/W148 and 94-32 by PCR based detection of specific markers. Non-Beijing strains were subjected to spoligotyping.</p><p><bold>Results</bold>. We found that 66.5% isolates belonged to the Beijing genotype, 12.8% — to LAM, 10.1% — to T, and 4.7% — to the Ural genotype. Multi-drug resistance (MDR) to anti-TB drugs was observed in 195 M. tuberculosis strains (45.9%). Moreover, Beijing genotype was more often isolated from patients with MDR-TB infection (PR = 2.09 (95% CI 1.6–2.74) and TB infection associated with HIV infection (PR = 1.14 (95% CI 1.01–1.31). Lethal outcome was double higher in patients infected with Beijing vs. non-Beijing strains, 28.6% vs. 14.0% (PR = 2.03; 95% CI 1.3–3.17). The risk factors were identified as follows: young age 18–44 years (RR = 1.7; 95% CI 1.18–2.7), co-morbidity with HIV (RR = 5.0; 95% CI 3.39–7.45), multiple (RR = 1.7; 95% CI 1.14–2.55) and extensive drug resistance (RR = 2.57; 95% CI 1.35–4.92), and association with the Beijing genotype (RR = 2.0, 95% CI 1.3–3.17).</p><p><bold>Conclusion</bold>. M. tuberculosis spread in the Omsk region is characterised by significant prevalence of the Beijing genotype, associated with multiple and extensive drug resistance. A significant association of adverse clinical outcomes and various factors, including association with the Beijing genotype, requires development of new approaches in the fight against tuberculosis.</p></abstract><trans-abstract xml:lang="ru"><p>Штаммы Mycobacterium tuberculosis, относящиеся к разным генетическим группам или линиям, характеризуются вариабельностью ряда биологических свойств, что в известной мере определяет эпидемиологические и клинические особенности течения туберкулезного процесса у больных.</p><p><bold>Целью</bold> исследования являлась оценка риска неблагоприятного исхода заболевания у больных туберкулезом, вызванным различными генотипами возбудителя.</p><p><bold>Материалы и методы</bold>. В исследование были включены 425 больных туберкулезом органов дыхания, состоявших на диспансерном учете в медицинских организациях фтизиатрического профиля Омской области в период с марта 2015 г. по июнь 2017 г. Мужчины составили 73,1%, средний возраст 39,9 лет, средний возраст женщин 42 года. Культивирование M. tuberculosis, определение лекарственной чувствительности, выделение ДНК проведено стандартными методами. Принадлежность штаммов M. tuberculosis к генотипу Beijing и его эпидемиологически значимым кластерам B0/W148 и 94-32 определяли на основе анализа специфических маркеров с помощью ПЦР. Генотипирование штаммов других генотипов осуществляли методом сполиготипирования.</p><p><bold>Результаты</bold>. 66,5% изолятов принадлежали генотипу Beijing, 12,8% — LAM, 10,1% — T, 4,7% — к генотипу Ural. Множественная лекарственная устойчивость к противотуберкулезным препаратам была обнаружена у 195 исследованных штаммов (45,9%).Штаммы генотипа Beijing чаще выделяли от больных мультирезистентным туберкулезом (PR = 2,09 (1,6–2,74) и туберкулезом, ассоциированным с ВИЧ-инфекцией (PR = 1,14; 95% ДИ 1,01–1,31). Летальный исход в 2 раза чаще регистрировался в группе больных, инфицированных микобактериями генотипа Beijing — 28,6% против 14,0% других генотипов. Риск смерти у больных туберкулезом связан с такими факторами, как молодой возраст в диапазоне от 18 до 44 лет (RR = 1,7; 95% ДИ 1,18–2,7), наличие коинфекции ВИЧ (RR = 5,0; 95% ДИ 3,39–7,45), наличие множественной (RR = 1,7; 95% ДИ 1,14–2,55) и широкой лекарственной устойчивости M. tuberculosis (RR = 2,57; 95% ДИ 1,35–4,92), а также с генотипом Beijing штамма M. tuberculosis, вызвавшего заболевание туберкулезом (RR = 2,0; 95% ДИ 1,3–3,17).</p><p><bold>Выводы</bold>. Особенностью популяции M. tuberculosis на территории Омской области является значительное распространение штаммов генотипа Beijing, обладающих множественной и широкой лекарственной устойчивостью. Выявленная статистическая связь неблагоприятных исходов болезни с рядом факторов, включая принадлежность возбудителя к генотипу Beijing, требует разработки новых подходов в борьбе с туберкулезом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Mycobacterium tuberculosis</kwd><kwd>genotype</kwd><kwd>Beijing</kwd><kwd>drug resistance</kwd><kwd>lethality outcome</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Mycobacterium tuberculosis</kwd><kwd>генотип</kwd><kwd>Beijing</kwd><kwd>лекарственная устойчивость</kwd><kwd>летальный исход</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
