Persistence of antibodies to pneumococcal vaccine in patients with chronic renal failure

Abstract

Antibody response to the 14-valent pneumococcal capsular polysaccharide vaccine was measured by the enzyme-linked immunosorbent assay (EIA) in 17 renal allograft recipients, 29 azotemic, 11 hemodialysis, and 33 control patients. The IgG, IgM, and IgA antibodies were measured against six pneumococcal antigen types 1, 3, 4, 6A, 8, and 19F. The control patients had the best antibody responses in the IgG and IgA antibody classes and the renal allograft recipients in the IgM class. The renal allograft recipients had significantly stronger antibody responses than the azotemic and hemodialysis patients. The hemodialysis patients had significantly weaker antibody responses than the control patients and the renal allograft recipients, and they also lost their antibodies most rapidly. Thus, the hemodialysis patients and probably some azotemic patients should be considered for revaccination.
