Hepatic manifestations of COVID-19 and effect of remdesivir on liver function in patients with COVID-19 illness.

COVID-19 has emerged as a major global health crisis since the first cases were reported in China in December 2019. Remdesivir is the only broad-spectrum antiviral approved by the US Food and Drug Administration to treat hospitalized patients with COVID-19 infection. Although the adverse effects of remdesivir are largely unknown, data from randomized controlled trials have demonstrated its deleterious effect on the liver. This review briefly addresses the hepatic manifestations of COVID-19 infection and the data regarding the efficacy and adverse effects of remdesivir on liver function when used in patients hospitalized with COVID-19. Through a literature search, we identified five randomized controlled trials, two case reports, and one case series, including a total of 2375 patients. Although mild transaminase elevation has been reported as a feature of COVID-19, there has been a concern of hepatotoxicity associated with the use of remdesivir. Based on the limited available data regarding the adverse effects of remdesivir on hepatic function, it is prudent to exercise caution by evaluating baseline liver function, avoiding the use of potentially hepatotoxic drugs, and closely monitoring liver function when using remdesivir in patients hospitalized with COVID-19.
