Host Immune Response to Clostridium difficile Infection in Inflammatory Bowel Disease Patients

Abstract

Patients with UC have lower IgA levels to C. difficile toxins compared with those with Crohn's disease and those after IPAA. Patients with IBD with prior CDI failed to demonstrate any increase in antitoxin IgG. Our findings suggest that IBD patients may benefit from immunization strategies targeting C. difficile toxins.
