title: Immunoglobulin M antibody to hepatitis B core antigen (IgM anti-HBc) as a marker of interferon therapy in patients with persistent hepatitis B virus infection.
abstract: Immunoglobulin M antibody to hepatitis B core antigen (IgM anti-HBc) was measured by radioimmunoassay in the sera of 96 HBV carriers. IgM anti-HBc was detected in 17 of 66 patients with chronic active hepatitis and in 4 of 11 with liver cirrhosis. This antibody was not present in asymptomatic carriers or in patients with chronic persistent hepatitis. Testing of sequential samples revealed that the presence of IgM anti-HBc indicated active replication of HBV and at the same time an immune response to the virus. The relationship between IgM anti-HBc and the response to interferon (IFN) therapy was also studied. Results showed that IgM anti-HBc is a useful marker of the efficacy of interferon therapy.
