The immune response to pneumococcal capsular polysaccharides (CPSs) and to the pneumococcal surface proteins cell wall-associated serine proteinase A (PrtA), pneumococcal surface protein A (PspA), and Streptococcus pneumoniae pullulanase A was evaluated in 45 patients with invasive pneumococcal disease compared with healthy adults. In serum from patients with meningitis and pneumonia, CPS antibody levels were low, compared with healthy adults; antibody levels did not differ between groups and did not change between phases. Levels of immunoglobulin G directed against the investigated pneumococcal surface proteins in patients with invasive pneumococcal disease were in the same range as in healthy adults. However, median PrtA and PspA antibody levels tended to increase during early convalescent phase. Low levels of CPS antibody, rather than of antibodies directed against the pneumococcal surface proteins, may predispose to invasive pneumococcal infection.
