结局指标

主要结局

Delay between the date of transplantation and the date of the Clinical and endoscopic relapse defined by a Pouchitis Disease Activity Index (Appendix) ≥ 7 points.

Delay between the date of transplantation and the date of the Clinical and endoscopic relapse defined by a Pouchitis Disease Activity Index (Appendix) ≥ 7 points.

次要结局

  • Relapse at week 24 defined as a Pouchitis Disease Activity Index (PDAI) superior or equal to 7 at week 24
  • Relapse at week 52 defined as a Pouchitis Disease Activity Index (PDAI) superior or equal to 7 at week 52
  • Delay within the transplantation and the instauration of an antibiotherapy or alternative treatment (immunosuppressive and/or biotherapy and/or corticotherapy)
  • Registered of adverse events defined by Common Terminology Criteria for Adverse Events (4.3) during 104 weeks post-transplantation according to ANSM recommendation.
  • Fecal microbiota engraftment at 8 weeks defined by : Sorensen’s index [receiver 8 weeks after FMT vs donor] > Sorensen’s index [receiver 8 weeks after FMT vs receiver before FMT]) with Sorensen’s index [receiver 8 weeks after FMT vs donor] = 0.6. To assess this endpoint, fecal microbiota composition will be analyzed for donor sample, receiver sample before FMT and 8 weeks after FMT, using 16S sequencing (Illumina Miseq technology)
  • IBD Disability Index at weeks -2, baseline, 8, 24, 52 and unscheduled visit
