Pneumococcal Polysaccharide Vaccination in Pediatric Inflammatory Bowel Disease

Le résumé fourni par la source

According to current recommendations, in addition to 13-valent pneumococcal conjugate vaccine (PCV13) series, all children with inflammatory bowel disease (IBD) aged ≥2 years, with planned or current immunosuppression, should receive pneumococcal polysaccharide vaccine (PPSV23). The primary aim was to determine the PPSV23 immunization rates in our pediatric IBD patients. The secondary aim was to determine the incidence of invasive pneumococcal disease in these patients. The IBD database at Le Bonheur Children’s Hospital was retrospectively reviewed to identify all cases diagnosed from 2003 to 2015. Out of 190 IBD patients, 106 on immunosuppressive drugs, whose immunization records could be obtained from the state database, were included in the study. Medical records were reviewed to determine infections seen in these patients from the time of diagnosis to date. IBD patients in our study ranged from age 2 to 18 years. Only 4 of 106 (3.7%) patients had received PPSV23 vaccine. Only 1 patient (0.9%) had probable pneumococcal disease and none with invasive pneumococcal disease. Clostridium difficile (11 patients) and Cytomegalovirus colitis (4 patients) were more commonly encountered. All our patients received the recommended PCV13 vaccine. The majority of our pediatric IBD patients did not receive PPSV23 vaccine. Fortunately, we did not see a high rate of invasive pneumococcal disease in our patients suggesting that they may be protected by the primary PCV13 vaccine series. Non-pneumococcal infections were more common in this population.
