摘要
Coronavirus disease 2019(COVID-19)poses an extremely serious global impact on public healthcare for individuals of all ages,including children.Increasing evidence has shown that liver abnormalities are commonly found in children with COVID-19,and age-related features in innate and adaptive response have been demonstrated.However,there are few reports and studies on COVID-19 related liver injury in children,and the data are scattered.So that many contradictions have arose.This situation is not only due to the serious ethical issues in studying pediatric patients with COVID-19,but also because of the short duration and wide coverage of the COVID-19 epidemic,the severity and complexity of clinical cases varied,as did the inclusion criteria for case reporting and patient outcomes.Therefore,we totaled the incidences,characteristics and pathomechanism of liver injury in children since the COVID-19 outbreak.The etiology of COVID-19-related liver injury is divided into three categories:(1)The direct mechanism involves severe acute respiratory syndrome coronavirus 2 binding to angiotensin-converting enzyme 2 in the liver or bile duct to exert direct toxicity;(2)the indirect mechanisms include an inflammatory immune response and hypoxia;and(3)COVID-19-related treatments,such as mechanical ventilation and antiviral drugs,may cause liver injury.In summary,this minireview provides fundamental insights into COVID-19 and liver dysfunction in children.
