Standardized Frozen Preparation for Transplantation of Fecal Microbiota for Recurrent Clostridium difficile Infection

While fecal microbiota transplantation (FMT) is historically known to be an effective means to treat recurrent Clostridium difficile infection (CDI) refractory to standard antibiotic therapies, the procedure is rarely performed. At least some of the reasons for limited availability are those of practicality, including aesthetic concerns and costs of donor screening. The objective of this study was to overcome these barriers in our clinical FMT program.

We report clinical experience with 43 consecutive patients who were treated with FMT for recurrent CDI since inception of this program at the University of Minnesota. During this time, we simplified donor identification and screening by moving from patient-identified individual donors to standard volunteer donors. Material preparation shifted from the endoscopy suite to a standardized process in the laboratory, and ultimately to banking frozen processed fecal material that is ready to use when needed.
