Clostridium difficile is the leading cause of nosocomial gastrointestinal illness in adult patients in hospitals. Even though C. difficile disease in adults has been well studied, research on pediatric C. difficile disease is still in its infancy. For many years it has been believed that C. difficile was a disease that affected only adults and was not a problem for children. This erroneous belief arose from the observation that neonates acquire C. difficile quickly (within 48 hours of birth) but show no intestinal symptoms (1–4). More recent evidence has been documented in case reports of pediatric C. difficile and outbreaks of C. difficile disease in pediatric populations (5– 7). Pediatric C. difficile disease has also been associated with the occurrence of severe complications and high mortality rates (8–10). The cascade of events in the pathogenesis of C. difficile disease is similar in children and adults. Normal intestinal microflora are disrupted by antibiotic exposure, medications, or surgery. If the child is then exposed to C. difficile (or its spores), colonization may occur, with production of toxins A and B. These toxins act on enterocytes, causing an inflammatory response and morphologic changes that lead to diarrhea or colitis. Host factors (age, diet, immune response) play an important role in determining whether C. difficile develops into asymptomatic carriage or active disease. Treatment for pediatric C. difficile disease usually relies on metronidazole or vancomycin, but clinical guidelines have not been defined for the pediatric population (11). As in adults, recurrent C. difficile disease that does not respond to conventional therapy develops in a proportion of children treated with antibiotic therapy.
