title: The impact of molecular biology in the diagnosis and management of viral hepatitis.
abstract: In recent years molecular biology techniques allowed an extraordinary progress in knowledge of hepatitis viruses. New informations have accumulated on the mechanisms of virus replication and on the pathogenesis of liver damage. In the clinical setting, simple noninvasive methods that use the same technological approach provide a useful diagnostic tool for infections of hepatitis B virus (HBV) and hepatitis delta virus (HDV). Using these tests we may define whether a carrier of hepatitis B surface antigen has a liver damage due to HBV or HDV or to other, non-virological causes. Detection of HBV-DNA and HDV-RNA in serum and liver can also be used as a guide for prognosis and therapy.
