RESUMO
The purpose of the present study was to measure the amount of antibody to hepatitis B core antigen (anti-HBc) in different populations by the immunoelectroosmophoresis method. High titers of anti-HBc, up to 1/4,096, were found in the acute stage of hepatitis B virus infections and in the chronic carrier state of hepatitis B surface antigen. In cases of acute hepatitis the anti-HBc titers gradually declined to low levels but persisted for the observation time of 5 to 6 years. Individuals positive for antibodies to hepatitis B surface and core antigens selected from a Swedish "normal" population showed still lower anti-HBc titers, indicating that the hepatitis B infection had occurred earlier. The anti-HBc titers in sera drawn at intervals of 4 years from a group of hemophilia patients may indicate previous infection with replicating hepatitis B virus rather than immunization with noninfectious hepatitis B core antigen material.
