Since January 2022, the omicron variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the most prevalent strain in Russia. This strain is associated with uncommon virus-induced lung injury and significantly lower hospitalization and mortality rates compared to previous variants.</p> <p><bold>AIM:</bold> This study aimed to assess the course of the omicron variant of SARS-CoV-2 in patients with end-stage kidney disease.</p> <p><bold>METHODS:</bold> The retrospective cohort study included 33 medical records of patients with end-stage kidney disease who had been treated for novel coronavirus infection at the Infectious Diseases Clinic of Kirov Military Medical Academy and Botkin Clinical Infectious Diseases Hospital between January 2022 and February 2024. Following a comprehensive analysis of the medical records, the patients were divided into two groups. Group 1 included 12 patients with novel coronavirus infection in the form of acute respiratory viral infection without lung involvement. Group 2 comprised 21 patients with virus-induced lung injury.</p> <p><bold>RESULTS:</bold> The omicron variant of SARS-CoV-2 frequently caused lung injury, including acute respiratory failure, in patients with end-stage kidney disease. The early stages of inpatient treatment for this group of patients were characterized by fever (≥ 37.2°C), tachycardia (≥ 90 bpm), National Early Warning Score ≥ 4, and prolonged viral shedding (12 [10; 18] vs 9 [7,5; 9,5] days, <italic>p</italic> = 0.002).</p> <p><bold>CONCLUSION:</bold> The high prevalence of comorbidities and frequent occurrence of virus-induced lung injury leading to acute respiratory failure underscore a unique cohort of patients with end-stage kidney disease requiring programmed hemodialysis and highlight the ongoing challenge of novel coronavirus infection, even during the spread of the omicron variant of SARS-CoV-2.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Новая коронавирусная инфекция у пациентов с терминальной стадией хронической болезни почек, до появления омикрон-варианта, отличалась склонностью к тяжелому течению и неблагоприятному прогнозу. C января 2022 г. доминирующим на территории России является омикрон-вариант коронавируса 2 тяжелого острого респираторного синдрома. В отличие от предшествующих вариантов, его характеризуют редкие вирусные поражения легких среди заболевших, значительно более низкие частота госпитализаций и летальность.</p> <p><bold>Цель</bold> — оценить течение заболевания, вызванного омикрон-вариантом коронавируса 2 тяжелого острого респираторного синдрома у пациентов с терминальной стадией хронической болезни почек.</p> <p><bold>Материалы и методы.</bold> В ретроспективное когортное исследование включено 33 истории болезни пациентов с терминальной стадией хронической болезни почек, проходивших стационарное лечение по поводу новой коронавирусной инфекции в клинике инфекционных болезней Военно-медицинской академии им. С.М. Кирова и Клинической инфекционной больнице им. С.П. Боткина с января 2022 г. по февраль 2024 г. После анализа историй болезни пациенты были распределены на две группы. В первую группу вошли 12 пациентов, перенесшие новую коронавирусную инфекцию в форме острой респираторной вирусной инфекции без поражения легких. Вторую группу составил 21 пациент с вирусным поражением легких.</p> <p><bold>Результаты и обсуждение.</bold> Установлено, что манифестная форма новой коронавирусной инфекции у пациентов с терминальной стадией хронической болезни почек, в период циркуляции омикрон-варианта коронавируса 2 тяжелого острого респираторного синдрома часто протекает с поражением легких, в том числе с развитием острой дыхательной недостаточности. В первые дни стационарного лечения у данной категории больных регистрировали наличие лихорадки (≥ 37,2°С), тахикардии (≥ 90 в мин), значение по Национальной шкале раннего предупреждения ≥ 4 баллов, более длительное вирусовыделение (12 [10; 18] против 9 [7,5; 9,5] дней, <italic>p</italic> = 0,002).</p> <p><bold>Заключение.</bold> Высокая распространенность сопутствующих заболеваний, частое развитие вирусного поражения легких с острой дыхательной недостаточностью доказывает уникальность когорты пациентов с терминальной стадией хронической болезни почек, получающих программный гемодиализ, и сохраняющуюся проблему новой коронавирусной инфекции даже в период циркуляции омикрон-варианта коронавируса 2 тяжелого острого респираторного синдрома.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>novel coronavirus infection</kwd><kwd>coronavirus</kwd><kwd>severe acute respiratory syndrome</kwd><kwd>chronic kidney disease</kwd><kwd>hemodialysis</kwd><kwd>omicron</kwd><kwd>virus-induced lung injury</kwd><kwd>virus carrier</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>новая коронавирусная инфекция</kwd><kwd>коронавирус</kwd><kwd>тяжелый острый респираторный синдром</kwd><kwd>хроническая болезнь почек</kwd><kwd>гемодиализ</kwd><kwd>омикрон</kwd><kwd>вирусное поражение легких</kwd><kwd>вирусоноситель</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Xiong F, Tang H, Liu L, et al.
