Abstract
Patients with cystic fibrosis (CF) have several risk factors for Clostridium difficile colonization such as frequent hospitalization and exposure to a broad array of antibiotics utilized for the control, eradication, and prophylaxis of respiratory pathogens. However, despite this high rate of colonization, the occurrence of C. difficile infection (CDI) in CF is rare. We report three children with CF who presented with severe community-associated CDI. All three children had complicated courses and one died. These children were in good health without significant morbidities, and were not frequently hospitalized nor did they receive frequent antibiotic courses. The occurrence of 3 severe cases within a 15-month period prompted us to report these cases and review the literature in regard to CDI. We reviewed the CF GI tract as possible risk factors for a high rate of C. difficile colonization in individuals with CF. Since a high percentage of individuals with CF are on gastric acid blocking agents, we also focused on gastric acid suppression as a potential risk factor for CDI.
