Efficacy of Fecal Microbiota Transplantation: Current Evidence on Clinical Cure for FMT for the Treatment of Recurrent C. difficile Infection

Controlled clinical trials and observational studies of Fecal Microbiota Transplantation (FMT) as a treatment for C. difficile infection (CDI) have reported cure rates ranging from 68%-100%. However, such trials and studies have varying definitions of recurrent C. difficile, use different FMT formulations and delivery methods, and treat different patient populations. This paper reviews important points to consider when extrapolating existing efficacy data to the unique situation of an individual patient.
