Background: Information regarding the clinical course of COVID-19 patients with liver injury is very limited, especially in severe and critical patients. 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 were collected 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).
Conclusions: Abnormal liver tests are commonly observed in severe and critical patients with COVID-19. The patients with severe illness should be closely observed to monitor liver function parameters, particularly when they present with independent risk factors of liver injury.
