Keywords

FMT, IBD

Brief summary

In this study the investigators will evaluate patients with IBD and and at least 2 confirmed c.difficile infections who will be undergoing FMT. The investigators will assess patients before FMT and then follow patients prospectively post FMT at week 1, 8 and 12 to assess for recurrence of c.difficile infection and IBD outcomes.

Interventions

DRUGFecal Microbiota Transplantation

Patients with at least 2 episodes of CDI and IBD will undergo a single FMT
