Выявить синдром цитолиза среди пациентов с COVID-19 и изучить потенциальную взаимосвязь характера течения COVID-19 и поражения печени. Материалы и методы. Обследовано 450 человек с диагнозом «U07.1 - Коронавирусная инфекция COVID-19, вирус идентифицирован», проходящих стационарное и амбулаторное лечение на базе ГБУЗ РБ Туймазинская ЦРБ. У больных оценивались КТ органов грудной клетки, биохимический анализ крови с подсчетом АЛТ, АСТ, общего белка, глюкозы, общего билирубина, АЧТВ, ПТИ, МНО, фибриногена. Результаты. По результатам биохимического анализа крови наличие цитолитического синдрома выявлено у 217 (48,2%) пациентов с COVID-19. Уровень АЛТ составлял 60 [23;72] Ед/л, а уровень АСТ составлял 45 [22;57] Ед/л. Между степенью тяжести течения и уровнем АЛТ выявлена прямая, сильная достоверная корреляционная связь (ρ=0,724, t=22,26, p&gt;95%). Прямая, достоверная корреляционная связь средней силы выявлена между степенью тяжести и процентом поражения легочной паренхимы (ρ=0,68, t=19,62, p&gt;95%), уровнем АСТ (ρ=0,68, t=19,53, p&gt;95%), возрастом больных (ρ=0,51, t=12,55, p&gt;95%), ИМТ (ρ=0,4, t=9,44, p&gt;95%). При сравнении степени поражения легочной паренхимы с уровнем АСТ выявлена прямая, достоверная корреляционная связь средней силы (ρ=0,5, t=12,38, p&gt;95%), так же, как и с уровнем АЛТ (ρ=0,5, t=11,98, p&gt;95%), уровнем общего белка (ρ=0,38, t=8,8, p&gt;95%), возрастом больных (ρ=0,35, t=7,85, p&gt;95%). Заключение. Клинические проявления COVID-19 характеризуются полисиндромностью, включая развитие цитолитического синдрома. Изменения функциональных показателей печени, обнаруживаемые при COVID-19, ассоциируются с прогрессированием и тяжестью инфекционного процесса, а также возрастом и ИМТ. Важным пунктом постковидной реабилитации пациентов является включение в курс гепатопротекторов.</p></abstract><trans-abstract xml:lang="en"><p>. Identify cytolysis syndrome among patients with COVID-19 and explore the potential relationship between the course of COVID-19 and liver damage. Materials and methods. 450 people with a diagnosis of "U07.1 - Coronavirus infection COVID-19, virus identified" were examined, undergoing and inpatient and outpatient treatment at Tuymazinskaya Central District Hospital. CT scan of the chest organs, biochemical blood test with calculation of ALT, AST, total protein, glucose, total bilirubin, APTT, PTI, INR, fibrinogen were evaluated. Results. The presence of cytolytic syndrome was detected in 217 (48.2%) patients. The ALT level was 60 [23;72] U/L, and the AST level was 45 [22;57] U/L. Between the severity of the course and the ALT level, a direct, strong significant correlation was revealed (ρ=0.724, t=22.26, p&gt;95%). A direct, significant correlation of moderate strength was found between the severity and percentage of lung parenchymal lesions (ρ=0.68, t=19.62, p&gt;95%), AST level (ρ=0.68, t=19.53, p&gt;95%), age of patients (ρ=0.51, t=12.55, p&gt;95%), BMI (ρ=0.4, t=9.44, p&gt;95%). Comparing the degree of damage to the lung parenchyma with the level of AST, a direct, significant correlation of moderate strength (ρ=0.5, t=12.38, p&gt;95%) was revealed, as well as with the level of ALT (ρ=0,5, t=11.98, p&gt;95%), total protein level (ρ=0.38, t=8.8, p&gt;95%), age (ρ=0.35, t=7.85, p&gt;95%. Conclusion. Clinical manifestations of COVID-19 are characterized by polysyndromicity, including a cytolytic syndrome. Changes in liver function parameters found in COVID-19 are associated with the severity of the infection, age and BMI. An important point in the post-COVID rehabilitation of patients is inclusion of hepatoprotectors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>аланинаминотрасфераза</kwd><kwd>аспартатаминотрансфераза</kwd><kwd>печень</kwd><kwd>синдром цитолиза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>alanine aminotransferase</kwd><kwd>aspartate aminotransferase</kwd><kwd>liver</kwd><kwd>cytolysis syndrome</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">WHO Coronavirus Disease (COVID-19) Dashboard.
