ARTICLE HIGHLIGHTS
Research background
Data on liver test abnormalities in asymptomatic and mild coronavirus disease 2019 (COVID-19) patients are rare.
Research motivation
This study evaluated the clinical characteristics of asymptomatic and mild COVID-19 patients with abnormal liver test results.
Research objectives
We aimed to determine the liver test abnormalities in asymptomatic and mild COVID-19 patients and their association with the viral shedding time, providing suggestions for health policymakers and medical practitioners.
Research methods
Clinical information and viral shedding time were collected retrospectively from 661 laboratory-confirmed asymptomatic and mild COVID-19 patients. Univariate and multivariate logistic regression models were performed in statistical analyses.
Research results
Elevated alanine aminotransferase was associated with obesity and a history of liver disease. Elevated aspartate transaminase (AST) was correlated with a history of liver disease age over 30 years. There was a correlation between AST ≥ 2× the upper limit of normal and a longer vital shedding time.
Research conclusions
Obesity and a history of liver disease are risk factors for liver test abnormalities. Liver test abnormality in asymptomatic and mild COVID-19 patients has clinical correlation with the viral shedding time.
Research perspectives
Attention should be given to liver tests in asymptomatic and mild COVID-19 patients, which has crucial clinical significance for evaluating the viral shedding time.
