Serum immunoglobulin levels and naturally occurring antibody titres against Streptococcus pneumoniae were measured in seven children aged 1-1.9 years with recurrent pneumococcal acute otitis media (AOM). Three of them had low IgG2 levels. Mean antibody levels of anti-pneumococcal IgG1 and anti-pneumococcal IgG2 were significantly lower in patients when compared to those of healthy controls and children who had less frequent episodes of AOM. Following treatment with intravenous immunoglobulin (IVIG) for 6 months, anti-pneumococcal IgG1 and IgG2 antibody levels increased and the number of episodes of AOM decreased in all patients. Following the discontinuation of IVIG therapy, no AOM episode occurred. Serum levels of anti-pneumococcal IgG1 and IgG2 were normal, which were measured in three subjects at 5, 6, and 12 months after the cessation of IVIG therapy. These results suggested that delayed maturation of anti-pneumococcal antibody production caused recurrent AOM and this condition was corrected by IVIG therapy.
