Clostridium difficile Infection in Children.

Clostridium difficile is an important cause of health care associated infections. The epidemiology of C. difficile infection (CDI) in children has changed over the past few decades. There is now a higher incidence in hospitalized children, and there has been an emergence of community-onset infection. A hypervirulent strain, North American pulse type 1, has also developed. Neonates and young infants have high rates of colonization but rarely have symptoms. The well-known risk factor for CDI in children age 2 years or older is antibiotic use. Inflammatory bowel disease and cancer are associated with increased incidence and severity of CDI. Nucleic acid amplification tests are now widely used for diagnosis given their rapid turnover and higher sensitivity and specificity. The treatment for an initial episode and first recurrence is oral metronidazole. Oral vancomycin is reserved for second recurrence or severe cases. A new treatment option, fecal bowel transplant, has been reported to be safe and effective in adults, and studies are now being conducted in children. [Pediatr Ann. 2018;47(9):e359-e365.].
