    Abstract
  •   Objective  To summarize and analyze the features of liver function in pediatric patients infected with Delta variant versus Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).  Methods  In this study, an analysis was performed for the liver function test results of the locally transmitted or imported pediatric patients with SARS-CoV-2 infection during isolation who were admitted to Guangzhou Eighth People's Hospital, Guangzhou Medical University, since May 21, 2021, and the clinical data and the constituent ratio of liver injury were compared between the pediatric patients infected with Delta variant and those infected with Omicron variant. The independent samples t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups.  Results  A total of 85 pediatric patients infected with SARS-CoV-2 were enrolled, among whom there were 32 (37.6%) pediatric patients infected with Delta variant and 53 (62.4%) pediatric patients infected with Omicron variant, and there were no significant differences between the two groups in age, sex, body height, body weight, and comorbidities (all P > 0.05). There were no significant differences between the two groups in alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase, total bilirubin, albumin, and cholinesterase (all P > 0.05), and the pediatric patients infected with Omicron variant had a significantly higher level of total bile acid (TBA) than those infected with Delta variant (Z=-2.336, P=0.020). However, the median values of TBA were within the normal range and the ratios of abnormal TBA were no significant difference between the two groups (P > 0.05). Among the 85 pediatric patients, 10 (11.8%) had a mild increase in liver function parameters, among whom 7 had an increase in TBA, 1 had an increase in ALT, 1 had increases in ALT and AST, and 1 had an increase in ALP. The analysis of liver injury in the pediatric patients infected with Delta variant or Omicron variant showed that there was no significant difference in the constituent ratio of liver injury caused by the two variants (6.3% vs 15.1%, χ2=0.691, P=0.406).  Conclusion  Mild liver injury is observed in pediatric patients infected with Delta and Omicron variants of SARS-CoV-2, but further studies are needed to evaluate the long-term influence of such infection on liver function.
