Introduction : Crohn's disease (CD) is an relapsing inflammatory bowel disease relatively frequent. Its prevalence is about 1 for 700 in France, affecting predominantly young adults. Its treatment is based on immunosuppressants that might be associated with potentially severe complications such as infection and cancers. Moreover, these treatments are expensive. The gut microbiota being involved in the disease pathogenesis, it can be considered as a potential therapeutic target.
CD pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota (called dysbiosis) in predisposed hosts. The complete replacement of a dysbiotic microbiota by a "healthy" one is thus an attractive strategy. Fecal transplantation (FT) has been used with success for a long time in the context of Clostridium difficile.
Hypothesis : Fecal transplantation allow the replacement of a dysbiotic microbiota by a " healthy " one with favorable impact on CD evolution.
Primary endpoint : In CD patient with colonic or ileo-colonic involvement put in remission with corticosteroids, Evaluate if FT can modify a dysbiotic fecal microbiota to be closer of the one of a healthy donor.
For the Receiver :
Once corticoid-induced remission will be achieved, the patient will be included and randomised to receive either FT or sham transplantation during a colonoscopy. The patient will be evaluated at week 2, 6, 10, 14, 18 and 24. At week 6, a colonoscopy will be performed.
For the Donor :
Donors will be recruited by poster advertising. When a receiver will be included, 3 donors will be contacted to attend an inclusion visit including physical examination as well as blood and stool screening for pathogen. The 3 donors will then come the day of the FT to donate their stool.

|Official Title:||Impact of Fecal transPlantAtion on MiCrobotia and hosT in Crohn's Disease|

Experimental: Fecal Transplantation
patients receiving the fecal transplant (fecal microbiota from a healthy donor)
Other: Fecal Transplantation
Fecal microbiota (50-100g of stool from donor resuspended in 250-350ml of physiological serum and filtered) given by infusion in coecum during colonoscopy
Sham Comparator: Sham Transplantation
patients receiving the vehicle (Physiological serum)
Other: Sham Transplantation
250-350ml of physiological serum given by infusion in coecum during colonoscopy
- FT success defined by : Sorensen's index [receiver 6 weeks after FT vs donor] > Sorensen's index [receiver 6 weeks after FT vs receiver before FT]) with Sorensen's index [receiver 6 weeks after FT vs donor] ≥ 0.6. [ Time Frame: 6 weeks after FT ]
In other words, FT success is reached if the fecal microbiota of the receiver 6 weeks after FT is closer of the fecal microbiota of the donor that of the receiver before FT.
Fecal microbiota composition will be assessed by 454 pyrosequencing (16S RNA) and microbiota comparison will be done using Sorensen's index.
- FT feasibility [ Time Frame: 6 weeks after FT ]evaluate the feasibility of the FT procedure (frequency of evaluable patients in each group)
- Clinical relapse rate in the 24 weeks following FT procedure [ Time Frame: 24 weeks following FT ]Clinical relapse defined by a Crohn's disease activity index (CDAI) > 220 points, or by a CDAI between 150 and 220 with an increase >70 compared with baseline, or by the need of surgery or to start a medical treatment for CD.
- Effect of FT compared to sham transplantation on CRP [ Time Frame: 6 weeks after FT ]Effect of FT compared to sham transplantation on CRP level.
- Effect of FT compared to sham transplantation on Leukocytes level [ Time Frame: 6 weeks after FT ]Effect of FT compared to sham transplantation on: Leukocytes level
- Effect of FT compared to sham transplantation on fecal calprotectin [ Time Frame: 6 weeks after FT ]Effect of FT compared to sham transplantation on: fecal calprotectin
- Effect of FT compared to sham transplantation on Crohn's Disease Endoscopic Index of Severity [ Time Frame: 6 weeks after FT ]Effect of FT compared to sham transplantation on: Crohn's Disease Endoscopic Index of Severity
- Effect of FT compared to sham transplantation on fecal microbiota composition [ Time Frame: 6 weeks after FT ]Effect of FT compared to sham transplantation on: fecal microbiota composition
- Effect of FT compared to sham transplantation on lymphocytes population in blood [ Time Frame: 6 weeks after FT ]Effect of FT compared to sham transplantation on: lymphocytes population in blood
- Effect of FT compared to sham transplantation on lymphocytes population in colon [ Time Frame: 6 weeks after FT ]Effect of FT compared to sham transplantation on: lymphocytes population in colon.
- Effect of FT compared to sham transplantation on colon transcriptomics [ Time Frame: 6 weeks after FT ]Effect of FT compared to sham transplantation on: colon transcriptomics.
