Clinical characteristics and risk factors for liver injury in COVID-19 patients in Wuhan

摘要

BACKGROUND Coronavirus disease 2019 (COVID-19) has become a worldwide pandemic. We investigated the clinical characteristics and risk factors for liver injury in COVID-19 patients in Wuhan by retrospectively analyzing the epidemiological, clinical, and laboratory data for 218 COVID-19 patients and identifying the risk factors for liver injury by multivariate analysis. AIM To investigate the clinical characteristics and risk factors for liver injury in COVID-19 patients in Wuhan. METHODS The 218 patients included 94 males (43.1%), aged 22 to 94 (50.1 ± 18.4) years. Elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were present in 42 (53.2%) and 36 (45.6%) cases, respectively, and 79 (36.2%) patients had abnormally elevated transaminase levels at admission. Patients with liver injury were older than those with normal liver function by a median of 12 years, with a significantly higher frequency of males (68.4% vs 28.8%, P 5 × ULN. Elevated γ-glutamyl transpeptidase was present in 45 (57.0%) patients, and 86.7% of these had a γ-glutamyl-transpeptidase level 135 U/L (3 × ULN). Serum alkaline phosphatase levels were almost normal in all patients. Patients with severe liver injury had a significantly higher frequency of abnormal transaminases than non-severe patients, but only one case had very high levels of aminotransferases. RESULTS Multivariate analysis revealed that male sex, high D-dimer level, and high neutrophil percentage were linked to a higher risk of liver injury. The early stage of COVID-19 may be associated with mildly elevated aminotransferase levels in patients in Wuhan. Male sex and high D-dimer level and neutrophil percentage may be important predictors of liver injury in patients with COVID-19. CONCLUSION Male sex and high D-dimer level and neutrophil percentage may be important predictors of liver injury in patients with COVID-19.
