COVID-19 is currently considered a systemic disease affecting the immune system, primarily, lungs, heart, central nervous system, kidneys, intestines, liver and spleen. Impaired liver function and the presence of biochemical changes in liver can be found in approximately 14-53% of adults infected with SARS-CoV-2. Impaired liver function in patients infected with COVID-19 may occur due to a direct effect of the virus on hepatocytes, as well as being secondary to factors such as a systemic inflammatory response of the infected host, the onset of hypoxia (associated with lung damage), multiple organ failure, or due to abusive treatment using overlapping and hepatotoxic drugs.
