Core Tip

Core Tip: There is a diversity of clinical manifestations of the coronavirus 2019 disease (COVID-19), ranging from classical presentations like fever, cough, and dyspnea to non-classical presentations like liver involvement. Direct injury, drug-induced hypoxia, abnormal liver function tests, cytokine storm, and a history of chronic hepatic diseases are the proposed mechanisms of liver involvement during the COVID-19 course. Liver involvement can determine the severity of the disease. Old age and a history of chronic diseases like diabetes mellitus are recognized risk factors for this involvement. Autoimmune hepatitis is an example of liver involvement following COVID-19 vaccination. However, complete vaccination with 3rd and 4th booster doses is required in patients with chronic liver diseases. We aim to summarize the various aspects of hepatic involvement during the COVID-19 course or following its vaccination.
