Purpose of review: Clostridiodes difficile infection (CDI) has unique challenges for diagnosis and treatment in pediatrics. Though new antibiotics and biologics are being approved or developed for adults, most of the pediatric therapies still rely on multiple or extended antibiotic courses. This review aims to highlight emerging evidence and our clinical experience with CDI in children and can help inform readers' approach to pediatric CDI.
Recent findings: Use of fidaxomicin for CDI in pediatrics has been shown to be to be non-inferior to vancomycin and is associated with higher global cure rates and decreased risk of recurrence. Fecal microbiota transplant is a successful emerging therapy with cure rates of up to 90%, though safety alerts should be noted. Diagnostic laboratory testing for C. difficile remains a challenge as it still cannot definitively distinguish between colonization and true infection, and this is particularly relevant to pediatric patients as they have the highest rates of colonization.
Summary: The diagnosis and treatment of C. difficile infection in pediatrics remain challenging and recommendations lag behind advances made in the adult field. Recent data suggests that use of fidaxomicin both as treatment of first episode or recurrences may be beneficial in pediatrics just as in adults. At an experienced center, FMT is associated with high cure rates. Bezlotuxumab a monoclonal antibody to toxin B that is already recommended for use in adults is being studied in children and should be available for clinical use soon. Oral vancomycin prophylaxis is also an emerging strategy for high-risk patients. Finally, a possible vaccine may be on the horizon for pediatrics.
