Abstract
BACKGROUND: There are limited data on antibody response to vaccination in patients with inflammatory bowel disease (IBD). In this study, we aimed to assess the immunogenicity of a booster dose of pertussis vaccine in pediatric patients with IBD and to compare their response with healthy controls. METHODS: We performed a multicenter, prospective, and controlled trial. Eligible for inclusion were children and adolescents (11-18 year olds), with no history of pertussis booster immunization after the age of 6 years or history of pertussis. Study population was divided into 4 groups: patients with IBD receiving no immunosuppressive therapy (group 1), those on thiopurines only (group 2), those onthiopurines and TNF-α agents (group 3), and healthy controls (group 4). Patients and controls received 1 dose of pertussis vaccine intramuscularly and were asked to record adverse effects for 3 days after vaccination. The primary outcome measure was adequate vaccine response, defined as the concentration of anti-Bordetella pertussis antibodies >11 μg/mL, measured between 4 and 8 weeks after the vaccination. RESULTS: In total, 138 subjects (111 patients and 27 controls) were enrolled in the study. Rates of adequate vaccine response did not differ among the 4 study groups (P = 0.11). Moreover, those patients with IBD who were on immunosuppressive therapy did not differ from those who were not (90.6% versus 88.2%, P = 0.37). No serious adverse effects in relation to the administration of vaccine were noted. CONCLUSIONS: Booster dose of pertussis vaccine was immunogenic and safe in pediatric patients with IBD.
