Abstract
PURPOSE OF REVIEW: We focus on two recent aspects of Clostridium difficile infection (CDI) in children, namely the emergence of community-associated CDI (CA-CDI) and the incidence and prevention of recurrent CDI. RECENT FINDINGS: Current surveys suggest that a large proportion of all pediatric CDI is acquired in the community. Risk factors and frequency estimates of pediatric CA-CDI, however, are confounded in babies and toddlers by a high rate of asymptomatic excretion, whose detection likely is exaggerated by the wide use of highly sensitive nucleic acid amplification tests. Recurrent diarrhea occurs in up to 25% of children with CDI. Preventative strategies for recurrent CDI in adults, namely pulse and taper antibiotic dosing, use of anti-CDI drugs with mild effect on the colonic microbiome, fecal microbiota transplantation, and passive immune therapy, currently are being tested in children. Future studies are required to better characterize community acquisition of CDI in children and to define the safety and effectiveness of preventative strategies for recurrent CDI.
