Liver Failure Associated to Hepatitis A in the Presence of Infection by Cytomegalovirus : Two Case Reports

Liver failure may occur due to extensive liver damage. Several etiologies may be associated to liver failure, in most cases, inducing strong or persistent inflammatory response, whose outcome is the extensive parenchymal loss. Some hepatotropic or nonhepatotropic viruses may induce severe liver damage, between them hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis E (HEV) and members of the Herpesviridae family. Here, we describe two cases of liver failure due to previous active infection by human cytomegalovirus (HCMV) followed by hepatitis A that occurred in immunocompetent individuals.
