В последние годы отмечается рост нетуберкулезных микобактериозов, в том числе в сочетании с туберкулезом легких. Диагностика ко-инфекции затруднена из-за сходства клинико-рентгенологической картины, а лечение представляет сложную задачу из-за разнородной лекарственной чувствительности возбудителей.</p></sec><sec><title>Клинический случай</title><p>Клинический случай. Описание клинического случая. Представлен случай пациентки 49 лет с рецидивом лекарственно-устойчивого туберкулеза легких, хронической обструктивной болезнью легких и выраженным дефицитом массы тела (индекс массы тела 15,0). При обследовании методом GenoType® Mycobacterium CM была верифицирована ко-инфекция M. tuberculosis и M. avium complex. Пациентке назначен индивидуальный режим химиотерапии, включавший бедаквилин, линезолид, клофазимин, левофлоксацин, циклосерин и кларитромицин.</p><p>Терапия осложнилась развитием лекарственно-индуцированной полинейропатии, потребовавшей отмены линезолида и циклосерина и коррекции доз. На фоне 8-месячного лечения достигнута конверсия мокроты (отрицательные микроскопия и посев), положительная рентгенологическая динамика и клиническое улучшение.</p></sec><sec><title>Выводы</title><p>Выводы. Данный случай демонстрирует принципиальную возможность успешного лечения ко-инфекции лекарственно-устойчивого туберкулеза и нетуберкулезных микобактериозов с использованием комбинации противотуберкулезных препаратов резерва и макролидов несмотря на диагностические ограничения, сложность выбора режима химиотерапии и маршрутизации для пациентов с ко-инфекцией.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. In recent years, there has been an increase in nontuberculous mycobacteriosis, including cases combined with pulmonary tuberculosis. Diagnosis of co-infection is challenging due to the similarity of clinical and radiological findings, while treatment presents a complex task because of the heterogeneous drug susceptibility of the pathogens.</p></sec><sec><title>Case Description</title><p>Case Description. We present a case of a 49-year-old female patient with recurrent drug-resistant pulmonary tuberculosis, chronic obstructive pulmonary disease, and severe underweight (Body Mass Index 15.0). Examination using the GenoType® Mycobacterium CM method confirmed co-infection with M. tuberculosis and M. avium complex. The patient was prescribed an individualized chemotherapy regimen including bedaquiline, linezolid, clofazimine, levofloxacin, cycloserine, and clarithromycin.</p></sec><sec><title>Results</title><p>Results. After 8 months of treatment, sputum conversion was achieved (negative sputum smear microscopy and culture), with favorable radiological changes and clinical improvement.</p></sec><sec><title>Conclusion</title><p>Conclusion. This case demonstrates the fundamental possibility of successful treatment of drug-resistant pulmonary tuberculosis and nontuberculous mycobacteriosis co-infection using a combination of reserve anti-tuberculosis drugs and macrolides, despite diagnostic limitations, the complexity of selecting a chemotherapy regimen, and challenges in patient routing for those with co-infection.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Лекарственно-устойчивый туберкулез</kwd><kwd>нетуберкулезные микобактериозы (НТМ)</kwd><kwd>микобактерии</kwd><kwd>микроскопия мокроты</kwd><kwd>BACTEC</kwd><kwd>Xpert® MTB/RIF.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Drug-resistant tuberculosis</kwd><kwd>nontuberculous mycobacteriosis (NTM)</kwd><kwd>mycobacterium</kwd><kwd>sputum microscopy</kwd><kwd>BACTEC</kwd><kwd>Xpert® MTB/RIF.</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>нет</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ratnatunga, C.
