Материал и методы: в исследование было включено 50 пациентов с подтвержденным COVID-19, имеющих повышение АЛТ и АСТ в ФПП. Средний возраст пациентов составил 55 [46; 66] лет. У 45 пациентов (90%) развилось поражение легких в виде пневмонии, ассоциированной с COVID-19. По данным КТ площадь поражения составила от 5 до 70%. Проанализированы аланинаминотрансфераза (АЛТ), аспартатаминотрансфераза (АСТ), общий билирубин, гамма-глутамилтрансфераза (ГГТ), щелочная фосфотаза (ЩФ), протромбин по Квику и общий белок. Результаты: Дебют цитолиза в среднем был на 8 [7; 11] день болезни. Уровень АЛТ повышался в 2,28 [1,41; 3,27] раз. Повышение АСТ коррелировало с изменениями АЛТ (r=0,86; р&lt;0,05), соответствовало повышению в 2,28 [1,41; 3,27] норм. Коэффициент де Ритиса составил 0,73 [0,49; 1,15]. Только у 2 пациентов (4%) наблюдалась гипербилирубинемия. Повышение ГГТ наблюдалось у 60% пациентов на 1,92 [0,79; 3,05] норм. Повышение ЩФ в 1,79 раз наблюдалось у одного пациента. Снижение протромбина по Квику отмечено только у 5 пациентов (10%), гипопротеинемия наблюдалась у 7 пациентов (14%). Изменения ФПП носили обратимый характер, нормализация показателей АЛТ была достигнута у 67%, АСТ - у 76% пациентов в течение месяца. Выявлена прямая корреляция АЛТ (r=0,52; p&lt;0,05) и АСТ (r=0,48; p&lt;0,05) с ферритином. Заключение: Изменения ФПП у пациентов с поражениями печени при COVID-19 характеризовались преимущественным повышением уровней АЛТ, АСТ, ГГТ и снижением коэффициента де Ритиса. Уровни общего билирубина, ЩФ и протромбина по Квику у большинства были в пределах нормы. Выявленные изменения в подавляющем большинстве случаев нормализовались в течение месяца.</p></abstract><trans-abstract xml:lang="en"><p>Aim: To evaluate features of changes of liver function tests (LFTs) in COVID-19. Methods: We included 50 patients with confirmed COVID-19 and abnormal LFTs. The average age was 55 [46; 66]. 45 patients (90%) were with COVID-19 associated pneumonia. Lung damage involvement according to lungs computed tomography ranged from 5% to 70%. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), quik’s prothrombin and total protein were analyzed. Results: The debut of liver cytolysis was on average 8 [7; 11] sick days of COVID-19. ALT levels elevated on average 2,28 [1,41; 3,27] times. An increase in AST correlated with changes in ALT (r=0,86; p&lt;0,05), it was 2,08 [1,44; 3] times. De Ritis ratio was 0,73 [0,49; 1,15]. Only 2 patients (4%) had hyperbilirubinemia. 60% patients had an increase in GGT - 1,92 [0,79; 3,05] times. 1,79 times ALP was in one patient only. Many patients had not signs of hepatocellular insufficiency - only 5 patients (10%) had decrease in Quik’s prothrombin; hypoproteinemia was observed in 7 patients (14%). The changes in LFTs were reversible, normalization of ALT was achieved in 67%, AST - in 76% of patients within a month. The levels of ALT (r=0,52; p&lt;0,05) and AST (r=0,48; p&lt;0,05) correlated with ferritin. Conclusions: Abnormal LFTs in COVID-19 were characterized by increase in ALT, AST, GGT and decreased de Ritis ratio. Total bilirubin, ALP, Quik’s prothrombin were normal in most patients. The identified changes in the majority of cases returned to normal within the month.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>функциональные пробы печени</kwd><kwd>синдром цитолиза</kwd><kwd>печень</kwd><kwd>новая коронавирусная инфекция</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liver function tests</kwd><kwd>cytolysis syndrome</kwd><kwd>liver</kwd><kwd>new coronavirus infection</kwd><kwd>COVID-19</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">Interim guidelines “Prevention, diagnosis and treatment of new coronavirus infection (COVID-19)”, Version 13.1.approved.
