New AGA guideline: Use FMT for the majority of recurrent C. diff patients

While we’ve expanded use of FMT for recurrent C. diff, we do not recommend fecal microbiota-based therapies for IBD and IBS.

AGA has published the first comprehensive evidence-based guideline on the use of fecal microbiota-based therapies for gastrointestinal disease. The guideline was published in Gastroenterology. 

Key takeaways 

  • Prevention with fecal microbiota-based therapies can be considered in patients after the second recurrence (third episode) of C. difficile infection (CDI) or in select patients at high risk for either recurrent CDI or a morbid CDI recurrence. 
  • In adults hospitalized with severe or fulminant CDI not responding to antimicrobial therapy, consider select use of conventional FMT as adjuvant treatment. 
  • Conventional fecal microbiota transplant as treatment for IBD or IBS should only be considered in the context of clinical trials. 

This guideline covers the use of conventional fecal microbiota transplant (FMT), performed most commonly via colonoscopy, as well as recently FDA approved therapies such as fecal microbiota live-jslm (REBYOTA) delivered via enema and fecal microbiota spores live-brpk (VOWST) delivered in an oral capsule.  

The guideline recommends FMT therapies only within the context of C. diff infection.
