| delta agent | A rare form of viral transfusion hepatitis. A defective viral agent that occurs only in association with hepatitis B infection. The delta agent may also increase the severity of hepatitis B infection. Complications include chronic persistent hepatitis and fulminant hepatitis. A test known as anti-delta agent antibody is positive and used to confirm the diagnosis. Treatment is the same as for hepatitis B. (27 Sep 1997) |
