Loss of detectable antibody to hepatitis B surface antigen in immunized patients with hemophilia but without human immunodeficiency virus infection.
We investigated the loss of detectable antibody directed against the hepatitis B surface antigen after immunization with hepatitis B vaccine in 55 patients who were seronegative for the human immunodeficiency virus and had hemophilia. Twenty percent of patients lost detectable antibody at a mean of 4.6 years after completion of immunization. Monitoring of hepatitis B serostatus or routine revaccination may be necessary.
