The objective of this study was to describe the characteristics and clinical course of liver function in patients admitted with severe and/or critical SARS-CoV-2 infection, as well as explore the risk factors that affect liver function in the enrolled COVID-19 patients.Methods: Information on clinical characteristics of 63 severe and critical patients with confirmed COVID-19 was collected. Data on patients’ demographics, laboratory characteristics, laboratory examination, SARS-CoV-2 RNA results and liver test parameters were acquired and analyzed.Results: The incidence of abnormal aspartate aminotransferase, alanine aminotransferase, and total bilirubin in the critical group was significantly higher than in the severe group (respectively 81.48%, 81.49%, 62.67%, and 45.71%, 63.88%, 22.86%, p < 0.05). The time for liver function parameters to reach their extremes was approximately 2– 3 weeks after admission. The independent factors associated with liver injury were patients with invasive ventilators, decreased percentages of neutrophils, lymphocytes and monocytes, and sequential organ failure assessment (SOFA) score ≥ 2 (p < 0.05).Conclusion: Abnormal liver tests are commonly observed in severe and critical patients with COVID-19. Severe patients infected by SARS-CoV-2 should be closely observed and monitored the liver function parameters, particularly when they present with independent risk factors for liver injury.Keywords: abnormal liver tests, coronavirus disease 2019, COVID-19, liver injury, pneumonia, severe acute respiratory syndrome coronavirus 2, SARS-CoV-2
