Core Tip

Core Tip: There have been numerous reviews evaluating the causative relationship between coronavirus disease 2019 (COVID-19) and liver pathology, given an emerging number of cases reporting COVID-19 induced liver injury. There are few reports noting the onset of hepatorenal syndrome (HRS) in the face of COVID-19 infection. Occurrence of HRS in any circumstance is typically an indicator of severe and perhaps life-threatening disease, potentially requiring liver transplantation. With a paucity in literature compilation on the associations between COVID-19 and HRS, we provide a review which discusses the purported pathophysiological mechanisms of COVID-19 induced HRS, and propose clinical assessment and management approaches in this scenario.
