Проанализировать течение СOVID-19 у пациентов с первичным билиарным холангитом (ПБХ).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В одноцентровом ретроспективном исследовании проведен опрос и анализ медицинской документации 144 пациентов с ПБХ.</p></sec><sec><title>Результаты</title><p>Результаты. Все пациенты (n = 144) получали базисную терапию урсодезоксихолевой кислотой (УДХК), 5 из них – также фибраты. Ответ на терапию (критерии EASL) достигнут у 30 человек. В период с марта 2020 по март 2021 г. СOVID-19 перенесли 50 пациентов (34,7 %), средний возраст составил 58,8 ± 10,7 года, из них цирроз печени определен у 16 человек. Легкое течение СOVID-19 наблюдалось у 34 (68 %) человек, среднетяжелое течение — у 14 (28 %), тяжелое — у 2-х (4 %), случаев крайне тяжелого течения не зафиксировано. Госпитализированы 12 пациентов, из них 8 получали кислородотерапию в связи со снижением SpO2 &lt; 94 %, потребности в применении других методов оксигенотерапии не было ни в одном случае. Длительность госпитализации составила в среднем 11,4 ± 5,7 суток. При COVID-19 наблюдалась более высокая исходная активность сывороточной щелочной фосфатазы (1,8 ± 1,0 против 1,7 ± 1,4 кратности верхнему пределу нормы, М ± SD, р = 0,04) и чаще встречалась неэффективность терапии УДХК (40 % против 19,1 % случаев, p = 0,04) в сравнении с пациентами, не болевшими COVID-19. Не получено достоверных различий в характеристиках течения ПБХ (стадии, ответе на терапию) и по возрасту в зависимости от тяжести течения COVID-19. Среди госпитализированных пациентов и нуждающихся в кислородной поддержке большую долю составили пациенты старшего возраста (58,3 и 62,5 % соответственно) и с наличием сопутствующих заболеваний (62,5 и 75 % соответственно). Пациенты, ранее не ответившие на терапию УДХК, чаще нуждались в кислородной поддержке в сравнении с пациентами, отвечающими на базисную терапию (p &lt; 0,01).</p></sec><sec><title>Выводы</title><p>Выводы. ПБХ не является фактором риска тяжелого течения СOVID-19. Возможен протективный эффект приема УДХК при инфекции SARS-CoV-2, что требует дальнейшего изучения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim of the study</title><p>The aim of the study. To analyze the course of COVID-19 infection in patients with primary biliary cholangitis (PBC).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. In a single-center retrospective study, survey and analysis of medical records of 144 patients with PBC was carried out.</p></sec><sec><title>Results</title><p>Results. All patients (n = 144) received basic therapy with ursodeoxycholic acid (UDCA), 5 of them received fibrates as well. Response to therapy (EASL criteria) was obtained in 30 people. Between March 2020 and March 2021, 50 patients (34.7 %) suffered COVID-19, with mean age of 58.8 ± 10.7 years, 16 of which were diagnosed with liver cirrhosis. Mild COVID-19 was observed in 34 (68 %) people, moderate course — in 14 (28 %), severe — in 2 (4 %), cases of extremely severe course were not recorded. 12 patients were hospitalized, 8 of which received oxygen therapy due to a decrease in SpO2 &lt; 94 %, there was no need for the use of other methods of oxygen therapy in any case. The duration of hospitalization was 11.4 ± 5.7 days. There was a higher initial activity of serum alkaline phosphatase (1.8 ± 1.0 versus 1.7 ± 1.4 times of the upper limit of normal, M ± SD, p = 0.04) in patients with COVID-19 infection and lack of UDCA therapy effectiveness was more prominent (40 % vs. 19.1 % of cases, p = 0.04) compared with patients who did not have COVID-19. There were no significant differences in characteristics of the course of PBC (stage, response to therapy) and age in correlation with severity of the course of COVID-19. Among hospitalized patients and those in need of oxygen support, large proportion were older patients (58.3 % and 62.5 %, respectively) and patients with concomitant diseases (62.5 % and 75 %, respectively). Patients who hadn`t previously responded to UDCA therapy were more likely to require oxygen support compared to patients responding to basic therapy (p &lt; 0.01).</p></sec><sec><title>Conclusion</title><p>Conclusion. PBC is not a risk factor for severe COVID-19. A protective effect of UDCA in SARS-CoV-2 infection is possible, which requires further investigation.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>первичный билиарный холангит</kwd><kwd>COVID-19</kwd><kwd>новая коронавирусная инфекция</kwd><kwd>заболевания печени</kwd><kwd>урсодезоксихолевая кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary biliary cholangitis</kwd><kwd>COVID-19</kwd><kwd>coronavirus infection</kwd><kwd>liver disease</kwd><kwd>ursodeoxycholic acid</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nardo A.D., Schneeweiss-Gleixner M., Bakail M., Dixon E.D., Lax S.F., Trauner M.
