Abstract
Introduction and objectives: Liver injury in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant- and Omicron subvariant-infected patients is unknown at present, and the aim of this study is to summarize liver injury in these patients.
Materials and methods: In this study, 460 SARS-CoV-2-infected patients were enrolled, five severe or critical patients were excluded, and 34 patients were also excluded because liver injury was not considered to be related to SARS-CoV-2 infection. Liver injury was compared between Omicron and non-Omicron variants- and between Omicron subvariant-infected patients; additionally, the clinical data related to liver injury were analyzed.
Results: Among the 421 patients enrolled for analysis, liver injury was detected in 76 (18.1%) patients, including 46 Omicron and 30 non-Omicron variant-infected patients. The ratios did not differ between Omicron and non-Omicron variant-, Omicron BA.1, BA.2 and BA.5 subvariant-infected patients (P>0.05). The majority of abnormal parameters of liver function tests were mildly elevated (1-3 × ULN), the most frequently elevated parameter of liver function test was γ-glutamyl transpeptidase (GGT, 9.5%, 40/421), and patients with cholangiocyte or biliary duct injury markers were higher than with hepatocellular injury markers. Multivariate analysis showed that age (>40 years old, OR=1.898, 95% CI=1.058-3.402, P=0.032), sex (male gender, OR=2.031, 95% CI=1.211-3.408, P=0.007), serum amyloid A (SAA) level (>10 mg/ml, OR=3.595, 95% CI=1.840-7.026, P<0.001) and vaccination status (No, OR=2.131, 95% CI=1.089-4.173, P=0.027) were independent factors related to liver injury.
Conclusions: Liver injury does not differ between Omicron and non-Omicron variants or between Omicron subvariant-infected patients. The levels of cholangiocyte or biliary duct injury biomarkers are dominant in SARS-CoV-2-infected patients.
Keywords: clinical analysis; liver injury; variant.
