Identification of Fecal Microbiota Biomarkers of Spondyloarthritis in Patients Suffering From Crohn's Disease.

Recruiting now · Not applicable

Conditions studied: Crohn Disease, Spondyloarthritis

In brief

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
