Core Tip

Core Tip: Severe acute respiratory syndrome coronavirus 2 infection is linked to significant liver injury, emerging from the facilitated entry of the virus into liver cells, including cholangiocytes and endothelial cells, due to increased receptor expression. This invasion triggers critical cellular alterations such as mitochondrial swelling, endoplasmic reticulum dilation, and hepatocyte apoptosis. Confirmed by biopsy or autopsy, the presence of viral particles in liver tissues correlates with extensive histological damage, characterized by necrosis, steatosis, cholestasis, and inflammation. Such findings highlight the acute hepatic impact of coronavirus disease 2019 (COVID-19) and signal the risk of severe long-term complications, such as COVID-19-associated sclerosing cholangitis, emphasizing the profound and enduring effect of the virus on liver health.
