The presence of human immunodeficiency virus (HIV) antibody in hemophilia patients was correlated with the loss of existing antibody to hepatitis B surface antigen (HBsAb) or the inability to develop an antibody to hepatitis B after receiving commercially available hepatitis B vaccine. Of the 137 patients studied 66 were HIV-positive and 71 were HIV-negative. Evidence of HBsAb (n = 44) or exposure to hepatitis vaccine (n = 12) was found in 85% of HIV positive patients at some time during their care in our clinic. However, 20% demonstrated subsequent antibody loss and/or did not respond to hepatitis vaccine. Loss of HBsAb or vaccine nonresponse was restricted to patients less than 21 years of age (72% of all patients). This result contrasted to only a 3% loss of HBsAb or vaccine nonresponse in the HIV-negative patients who had acquired the HBsAb (n = 23) or were given the hepatitis vaccine (n = 29). This result suggests that loss or alterations of hepatitis B immunity occur in association with HIV infection or exposure.
