Liver ultrasound evaluation of acutely increased liver function tests of COVID-19 hospitalized patients.

Background: The incidence of hepatic abnormalities has been notably higher following the coronavirus disease 2019 (COVID-19) infection, attributed to the virus's entry into cells via angiotensin-converting enzyme 2 (ACE2) surface expression. The gastrointestinal tract's significant ACE2 expression, alongside a lesser degree in the biliary epithelium, has been implicated in gastrointestinal symptoms and liver injury.

Purpose: The aim of this study was to determine whether specific ultrasonographic findings in the liver correlate with acute increases in liver function tests (LFTs) among hospitalized patients.
