HEPATIC MANIFESTATIONS IN COVID-19: APPROACHES ON THE MECHANISMS, LIVER INJURIES AND DRUG INTERACTIONS

Abstract

The current pandemic caused by SARS-CoV-2 originated in the city of Wuhan, China with an outbreak of pneumonia. The reported symptoms were mostly respiratory, but mounting evidence began to indicate that COVID-19 could reach other organs and systems. Among the gastrointestinal symptoms, liver involvement appears to be more common, with changes in liver enzymes (ALT and AST) being the first sign. Therefore, the present study aims to evaluate and discuss the hepatic manifestations in COVID-19 as the infection, manifestations, and drug effects. The study was based on a literature review, of a qualitative nature and an exploratory type. The mechanism that SARS-CoV-2 uses to reach the liver is still uncertain, there are currently 3 hypotheses: ACE2 receptors in cholangiocytes, cytokine storm, and drug-induced liver injury, due to the increase in the indiscriminate use of hepatotoxic drugs without scientific comprovation, hydroxychloroquine can lead to fulminant hepatic failure and azithromycin potentiates these effects, the role of remdesivir on the liver are still uncertain. Liver damage in mild cases of COVID-19 can be transient, but doctors should monitor and be alert to any changes in liver enzymes. When severe liver damage occurs, liver protective drugs have usually been given to these patients. Thus, this review provides a review of hepatic impairment and the management of patients considering the main studies carried out to date.
