title: Hepatitis in clinical practice. 2. Non-A non-B and delta hepatitis.
abstract: Non-A non-B (NANB) hepatitis has at least two distinct causative agents. NANB hepatitis can lead to chronic liver disease, cirrhosis, and hepatocellular carcinoma. No definitive policy exists to exclude this disease as a cause of posttransfusion hepatitis. Delta agent is epidemiologically linked to hepatitis B virus (HBV) infection, either as a coinfection or as a superinfection in chronic hepatitis B surface antigen carriers. Recognition of hepatitis due to delta agent will probably increase as testing for this agent becomes more available and its presence becomes more generally well known throughout the medical profession.
