Abstract:
Objective:To investigate the incidence of liver injury in patients with coronavirus disease 2019 (COVID-19), and to explore its impact on the condition and prognosis of patients.Methods:The medical records of 67 patients with COVID-19 who presented with pneumonia hospitalized at Tongji Hospital, Huazhong University of Science and Technology from February 11 to March 28, 2020 were collected. The results of liver biochemistry and coagulation function test at admission were analyzed. Data were compared by chi-square test, analysis of variance or Kruskal-Wallis H test. Results:Among 67 patients, total bilirubin increased in seven (10.4%) patients, which was slightly abnormal, albumin decreased in 36(53.7%) cases, and was below 30 g/L in 15(22.4%) cases, alanine transaminase (ALT) and aspartate transaminase (AST) were elevated in 19(28.4%) and 12(17.9%) cases, respectively. A total of 22(32.8%) cases had elevated ALT and (or) AST. The incidences with elevated ALT and (or) AST in moderate and severe patients were 33.3%(10/30) and 26.9%(7/26), respectively. Five of 11 critical patients had elevated ALT and (or) AST. There was no significant difference among the three groups ( χ2=1.21, P=0.546). Abnormal alkaline phosphatase and (or) γ-glutamyl transpeptidase were observed in 11(16.4%) cases. The prolongation of prothrombin time (PT) and activated partial thromboplastin time (APTT) occurred in 10(14.9%) and 17(25.4%) patients, respectively, while most of them were slightly abnormal. Only one patient presented with prolongation of PT and APTT meeting the standard of liver failure. A total of 61.2%(41/67) and 65.7%(44/67) of cases showed increase of fibrinogen and D-dimer, respectively, and 28.4%(19/67) and 19.4%(13/67), respectively increased to an obvious extent. The albumin levels in moderate, severe and critical patients were (37.85±6.19) g/L, (32.96±4.33) g/L and (33.02±3.63) g/L, respectively, which were significantly different ( F=7.36, P=0.001). There were significant differences in PT, APTT, fibrinogen and D-dimer among the three groups ( F=3.22, 3.31, 4.06 and H=17.63, respectively, all P<0.05). Conclusions:COVID-19 only leads to mild liver injury and has only mild impact on liver function. The decrease of albumin level and the increase of fibrinogen and D-dimer may be early predicting indexes for the disease severity.
