Identification of Fecal Microbiota Biomarkers of Spondyloarthritis in Patients Suffering From Crohn's Disease. Identification de Biomarqueurs de SPondylArthrite Chez Les Patients Atteints de Maladie de CROhn présents Dans le MICrobiote fécal.
The MICROSPA project aims to compare gut microbiota, serum cytokines, and PBMC of patients suffering from Crohn's disease (CD) associated or not to spondylarthritis (SpA). 3 groups of patients will be analyzed: patients suffering from CD alone, patients suffering from SpA alone, patients suffering from CD and SpA. One group of healthy controls will be analysed as a comparator. Fecal microbiota will be determined by bacteriome, virome and fungome NGS sequencing
