Immunization Coverage in Children with Inflammatory Bowel Disease.

Patients suffering from inflammatory bowel diseases (IBD) are at increased risk of infections, mainly due to immunosuppressive treatment. Moreover, infections may cause flares of IBD. Vaccination is the most effective way of preventing many infections. The aim of this study was to evaluate the vaccination status of Polish children with IBD. Individual immunization cards of children with IBD and healthy controls were reviewed. Demographic data such as age, sex, and IBD history, including therapy type, were collected. We enrolled 267 children into the study, including 214 children with IBD and 53 controls. None of the children had completed the full up-to-date routine childhood immunization schedule recommended in Poland. Controls were more than 4 times more likely to be vaccinated than the IBD patients, with the vaccines that enjoy the insurance reimbursed (OR 4.1, 95% CI 2.2-7.9). In conclusion, the study demonstrates a poor vaccination status in children suffering from IBD.
