An Intragastric Fecal Microbiota Transplantation Program for Treatment of Recurrent Clostridium difficile in Children is Efficacious, Safe, and Inexpensive

Objective To assess the safety, efficacy, and relative expense of a nurse-led fecal microbiota transplantation (FMT) program for the treatment of recurrent Clostridium difficile infection (CDI). Study design Retrospective cohort study design in children aged 1-18 years with recurrent CDI. The intervention was an intragastric FMT with stool derived from a donor stool bank. Primary outcome was resolution of diarrhea at 3 months post-transplantation. A secondary analysis compared charge data associated with FMT by intragastric delivery vs administration by colonoscopy or nasoduodenal tube. Results A total of 47 intragastric FMT procedures were performed in 42 children (median age 9 years) with recurrent CDI. Response to treatment varied by disease status, with 94% success in previously healthy children, 75% in medically complex children, and 54% in children with inflammatory bowel disease ( P  = .04). FMT via intragastric delivery showed lower facility and professional charges by 85% and 78% compared with delivery via colonoscopy and radiology-placed nasoduodenal tube, respectively. The use of stool derived from a donor stool bank decreased charges by 49% compared with charges associated with the use of a donor who was a relative. Conclusion A nurse-led intragastric FMT procedure using stool derived from a donor stool bank is a relatively inexpensive and efficacious treatment for recurrent CDI in children. Intragastric FMT success in children was attenuated by the presence of underlying disease, particularly inflammatory bowel disease.
