Clostridium difficile-associated diarrhea in a pediatric hospital

This retrospective cohort analysis examined the risk factors, symptoms, and severity of disease associated with C. difficile in pediatric inpatients. Risk factors for a C. difficile-positive test were an oncologic diagnosis, diarrhea of more than 2 days' duration, and gastrointestinal symptoms, especially abdominal pain. Over a 3.5-year period, there was a total of 22 C. difficile-positive patients, and most had mild, self-limiting diarrheal illness. No cases of C. difficile diarrhea were identified. Seventy-eight percent of the C. difficile-positive patients were found to have alternate risk factors for diarrhea. Our data indicate that C. difficile rarely causes severe diarrhea in pediatric inpatients and that C. difficile-positive testing should be limited to patients with severe prolonged diarrhea and abdominal pain.
