Hepatitis B virus associated with severe acute respiratory syndrome coronavirus 2 infection: a case report

The patient's history of well-controlled hepatitis B suggests that, in this case, liver dysfunction was secondary to coronavirus disease 2019 manifestations such as the cytokine storm, respiratory failure, and drug-induced hepatotoxicity. The patient eventually recovered, and there was no demonstrable reactivation of hepatitis B after discharge. Coronavirus disease 2019 can thus affect liver function severely and primarily, yet without necessarily interacting with adequately managed hepatitis B.
