Antibody to human immunodeficiency virus (HIV) and suboptimal response to hepatitis B vaccination.

To analyze the relation between human immunodeficiency virus (HIV) infection and the antibody response to plasma-derived hepatitis B vaccine. Open-label longitudinal cohort study; blinded laboratory studies. University-affiliated municipal hospital. Homosexually active men with negative assays for hepatitis B surface antigen (HBsAg), hepatitis B core antigen, and antibody to HBsAg; recruited in a sexually transmitted disease clinic or referred from community practitioners. Immunization with 20 micrograms of plasma-derived hepatitis B virus vaccine intramuscularly, repeated after 1 and 6 months; standardized evaluation at entry and at 1, 2, 6, and 7 months. Low antibody response or nonresponse to vaccination occurred in 7 of 16 HIV-seropositive patients, compared with 6 of 68 HIV-seronegative patients (P = 0.002). Median levels of antibody to HBsAg 7 months after the first vaccine dose were 205.3 sample ratio units for HIV-seronegative patients and 15.5 sample ratio units for HIV-seropositive patients. By multivariate analysis, vaccine response was associated with HIV antibody status and not with cytomegalovirus infection, lymphocyte subset results, or impaired cutaneous delayed hypersensitivity. Infection with HIV is associated with suboptimal antibody response to plasma-derived hepatitis B virus vaccine. Determination of antibody levels after vaccination in HIV-seropositive patients may be warranted.
