Detailed Description
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.
Methodology
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.

Experimental: Fecal Transplantation
patients receiving the fecal transplant (fecal microbiota from a healthy donor)
|
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

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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. |
