Human immunodeficiency virus (HIV)-infected persons manifest decreased antibody responses to pneumococcal polysaccharide vaccines. Since human antibody responses to polysaccharides are often restricted, the molecular structure of antibodies elicited by a 23-valent pneumococcal vaccine was analyzed. Anti-idiotypic reagents were used to detect V(H)1, V(H)3, and V(H)4 gene usage by antibodies to pneumococcal capsular polysaccharides in HIV-uninfected and HIV-infected subjects by ELISA. HIV-uninfected persons generated beta-mercaptoethanol-sensitive and -resistant antibodies to pneumococcal capsular polysaccharides expressing V(H)3 determinants recognized by the D12, 16.84, and B6 monoclonal antibodies; antibodies expressing V(H)1 determinants were not detected, and V(H)4 determinants were expressed by beta-mercaptoethanol-sensitive antibodies only; and HIV-infected subjects had significantly lower capsular polysaccharide-specific and V(H)3-positive antibody responses. These findings confirm decreased antibody responses to pneumococcal vaccination in HIV-infected persons and suggest that their poor responses may result from HIV-associated depletion of restricted B cell subsets.
