About this trial
Autoinflammatory diseases (AID) are genetic diseases responsible for excessive activation of innate immunity leading to blood inflammation and systemic symptoms. Most patients display digestive involvements that may resemble inflammatory bowel disease. Several studies have found dysbiosis in some AID. Gut microbiota can communicate with the host via gut-derived metabolites (Fatty acids, tryptophan, bile acids) that may have either pro-inflammatory or anti-inflammatory effects. Some metabolites can also activate the Aryl hydrocarbon receptor (AhR) pathway, which enhances gut barrier. Gut barrier dysfunction has already been associated with AID. Therfore, dysbiosis could promote digestive and inflammatory involvements in genetically predisposed patients via perturbations of gut-derived metabolites.
Eligibility criteria
Qualifiers
Patients with autoinflammatory diseases aged >12 years and followed in the CEREMAIA internal medicine department present for consultation or day hospital for a routine care visit.
FMF defined by the Eurofever/PRINTO criteria
or CAPS définie by the Eurofever/PRINTO criteria
or MKD defined by the Eurofever/PRINTO criteria
Disqualifiers
Antibiotic therapy within 3 months prior to inclusion. If antibiotic therapy was initiated between inclusion and stool collection (data collected on the self-administered questionnaire accompanying the stool collection), the analysis data performed prior to antibiotic therapy will be retained, and the stool will not be analyzed.
Current infection on the day of inclusion
