Viral Hepatitis B and C

Chronic hepatitis B (HBV) and C virus (HCV) infection can lead to liver cirrhosis, hepatocellular carcinoma and death. Treatment of these worldwide prevalent infectious diseases is subject to intensive research efforts with development of new antiviral substances and optimization of treatment strategies using molecular markers. The goal of HBV and HCV treatment is control and elimination of viral replication, respectively, thereby preventing hepatitis-associated complications. While interferon alfa is used less frequently to treat hepatitis B today, it is still (in the pegylated or albumin-fused form) an essential component of hepatitis C therapy. The growing number of targeted therapies such as new nucleos(t)ide analogs, HCV protease and RNA polymerase inhibitors and other new compounds has added complexity to the treatment of viral hepatitis. This update summarizes the current standard of care as well as new developments in chronic hepatitis B and C therapy.
