摘要
It is hypothesized that liver impairment caused by coronavirus disease 2019(COVID-19)infection might play a central role in severe clinical presentations.Liver injury is closely associated with severe disease and,even with antiviral drugs,have a poor prognosis in COVID-19 patients.In addition to the common hepatobiliary disorders caused by COVID-19,patients with pre-existing liver diseases demand special considerations during the current pandemic.Thus,it is vital that upon clinical presentation,patients with concurrent pre-existing liver disease associated with metabolic dysfunction and COVID-19 be managed properly to prevent liver failure.Careful monitoring and early detection of liver damage through biomarkers after hospitalization for COVID-19 is underscored in all cases,particularly in those with pre-existing metabolic liver injury.The purpose of this study was to determine most recent evidence regarding causality,potential risk factors,and challenges,therapeutic options,and management of COVID-19 infection in vulnerable patients with pre-existing liver injury.This review aims to highlight the current frontier of COVID-19 infection and liver injury and the direction of liver injury in these patients.
