The recent outbreak of coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has resulted in a world-wide pandemic. Disseminated lung injury with the development of acute respiratory distress syndrome (ARDS) is the main cause of mortality in COVID-19. ⋯ The spectrum of liver injury in COVID-19 may range from direct infection by SARS-CoV-2, indirect involvement by systemic inflammation, hypoxic changes, iatrogenic causes such as drugs and ventilation to exacerbation of underlying liver disease. This concise review discusses the potential pathophysiological mechanisms for SARS-CoV-2 hepatic tropism as well as acute and possibly long-term liver injury in COVID-19.

Rate of SARS-CoV-2 infection and impact of liver fibrosis stage upon infection rates in persons with hepatitis C virus (HCV) infection are unknown. ⋯ Testing rates among persons with HCV are very low. Persons with infection are more likely to be Black, have a higher body mass index and diabetes or stroke. The degree of liver fibrosis does not appear to have an impact on infection rate.
