Abstract

Many children with recurrent sinopulmonary infections fail to mount an adequate humoral response following immunization with polysaccharideantigens. At present there are no controlled studies comparing responses to pneumococcal immunization in children with recurrent infectionsand a healthy, age-matched cohort. Immunological evaluation was performed on 66 children with recurrent sinopulmonary infections, aged 2-5 years (mean 3.06 +/- 0.92). A control group included 28 healthy, age-matched controls (mean 3.14 +/- 0.88 years). Both groups were immunizedwith 23 valent pneumococcal vaccine, and titers were measured before and 4 weeks after immunization. Antibody levels to 12 pneumococcal serotypes were measured via radioimmunoassay. Geometric preimmunization mean titers in the control group were 215.5 +/- 157 ngAbN/ml rising to 989.5 +/- 745 ngAbN/ml compared to 77.71 +/- 38.4 ngAbN/ml increasing to 446.7 +/- 406 ngAbN/ml in the study group (p < .05). Serotypes 3, 4, 7F, 8, 9N, and 18C were the most immunogenic, while serotypes 6A and14 were the least. Overall, the control group responded to 7.71 +/- 1.24 serotypes versus 5.1 +/- 2.0 in the study group (p < .05), where postimmunization titers at least doubled and rose to greater than or equal to 300 ngAbN/ml. All controls responded to at least five or more serotypes, 26/28 responded to 6 or more. In contrast, only 38/66 (57%) of study patients responded to five or more serotypes, and only 27/66 (41%) responded to at least 6 of 12. Preimmunization titers of greaterthan 300 ngAbN/ml were present in 30% (102/336) of the control serotypes; however, only 53 of these (52%) doubled post immunization; 22% ofthe elevated titers decreased post immunization. Markedly elevated titers greater than or equal to 500 ngAbN/ml were present in 20% (69/336) of the preimmunization serotypes, only 39% of these doubled post immunization. Twenty-three valent pneumococcal vaccine is immunogenic in young, healthy children. A significant percentage of children with recurrent sinopulmonary infections fail to produce adequate serotype specific antibodies following pneumococcal immunization.
