Brief Summary:
The goal of this pilot study is to test whether Fecal Microbiota Transplant (FMT) would be an effective antibacterial treatment for managing Adherent-invasive Escherichia coli (AIEC) colonization in Crohn's disease (CD) patients.
It aims to assess the safety of FMT in patients with clinically inactive or mild to moderate CD and to determine the presence of AIEC before and after FMT.
Participants will receive FMT via colonoscopy and have a follow-up colonoscopy at the end of the study.

Detailed Description:
Experimental and observational data suggest that intestinal inflammation in Crohn's Disease (CD) arises from abnormal immune response to intestinal microbiota in genetically susceptible individuals. Genes that regulate innate immune response, intestinal barrier function and bacteria killing of intracellular pathogens have been associated with an increased risk for developing CD in Caucasian populations. The search for specific pathogens in CD has identified in the intestinal mucosa of patients several candidates. One with much supporting evidence is the adherent invasive Escherichia coli (AIEC). Since its discovery in 1998, several groups have reported a higher prevalence of AIEC in CD patients compared to healthy subjects and confirmed their pro-inflammatory potential. A growing body of work indicates that different host environments can select such AIEC pathobiont. AIEC colonization in mice leads to strong inflammatory responses in the gut suggesting that AIEC could play a role in CD immunopathogenesis.
Faecal microbiota transplantation (FMT) represents a clinically feasible way to restore the gut microbial ecology and has proven to be a breakthrough for the treatment of recurrent Clostridium difficile infection. Clinical trials are being conducted to evaluate its use for other conditions including inflammatory bowel disease, irritable bowel syndrome, diabetes mellitus, non-alcoholic steatohepatitis and hepatic encephalopathy. Efficacy of FMT on CD endoscopic lesions and AIEC colonization remains to be demonstrated.
