Clostridium difficile Carriage and Serum Antitoxin Responses in Children with Inflammatory Bowel Disease

Abstract

Asymptomatic toxigenic C. difficile carriage was increased in pediatric outpatients with IBD compared with controls. Proton pump inhibitor use was associated with increased carriage. Antibody responses to C. difficile toxins were increased in IBD, potentially promoting asymptomatic colonization. Future studies should identify the risk factors for symptomatic C. difficile in pediatric IBD.
