Fecal microbiota transplantation (FMT) is becoming an increasingly accepted treatment for recurrent Clostridium difficile infection (CDI).
Overall resolution rates in the range of 90% have been reported in the literature1-3 though multiple doses may be necessary to achieve this cure rate.4-5
There are still many unknowns about the therapy including questions about donor vs. patient factors in therapy success.
Conventional procedure has been to use a second donor in case of treatment failure.
The relative importance of the donor was assessed in the context of a Phase 2 study of a next-generation FMT drug.
