Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Ileocecal surgical resection is required in some patients with complicated or refractory CD. Unfortunately, post-surgical disease recurrence happens in up to 40% of cases, probably defining a subgroup of CD patients with a particular aggressive form of the disease. The complete microbiome (in gastrointestinal and extraintestinal sites) in CD patients that develop early post-surgical recurrence, as well as the association to innate immunity alterations, has not yet been studied.
The primary aim of the study is to explore the bacterial microbiome of CD patients and its association with early post-surgical recurrence and clinical or genetic variables related to innate immunity. To achieve this, the bacterial DNA present in mesenteric fat and ileal tissue (inflamed and non-inflamed) from surgical resection samples as well as blood samples from CD patients will be studied. Genetic polymorphisms, relevant clinical data and disease recurrence will also be evaluated.
The investigators hypothesize that bacterial translocation to the mesentery fat near the inflamed intestine is one of the mechanisms for perpetuation and chronicity of inflammation and therefore post-surgical recurrence in CD. The investigators expect to find a distinctive bacterial profile (in quantity and quality) in the mesenteric fat of patients with early post-surgical recurrence and/or with genetic variants that cause alterations in innate immunity.
The study of the microbiome in CD could help to identify the patients with a more aggressive disease form that will probably present early post-surgical recurrence, and could raise the possibility of microbial modulation as therapy for CD.
