Clinical significance: |
Hepatitis D virus (HDV) infection requires the surface antigen from HBV and may occur as an acute infection with HBV or as a superinfection of a chronic HBV infection. HDV should be considered in any individual who tests positive for the HBV surface antigen (HBsAg). The presence of HDV RNA in the serum reflects viral replication in the liver. HDV-HBV co-infection is considered the most severe form of chronic viral hepatitis due to more rapid progression towards liver-related death and hepatocellular carcinoma. HDV RNA, quantitative real-time PCR can assist with diagnosis of HDV infection as well as monitoring of treatment. |
