Abstract
HIV-infected individuals have excess rates of invasive pneumococcal disease. We investigated risk factors for nasopharyngeal pneumococcal colonization at baseline and after 9 months in 96 HIV patients immunized twice with 7- valent pneumococcal conjugate vaccine ±1mg CPG 7909.
In total, 22 patients (23%) were colonized, 11 at baseline only, four at both baseline and 9 months, and seven at 9 months only. Compared to non-colonized patients, more colonized patients were smokers, had lower CD4+ nadir and had an AIDS-diagnosis. Immunization, antiretroviral treatment and the CPG adjuvant had no impact on colonization. These results suggest preventive strategies in addition to pneumococcal immunization.
