Brief Summary
Spondyloarthritis and inflammatory bowel diseases are common diseases, frequently met together in overlap syndromes. Their physiopathology remains puzzling. A strong role of gut microbiota has been recently put forward to explain the development of inflammatory bowel diseases, and is suspected to play an important role in rheumatoid diseases. Anti-Tumor Necrosis Factor (anti-TNF) alpha are effective and safe drugs in the treatment of both digestive and rheumatoid inflammatory diseases. The way they work is unclear, and the clinical response to this treatment is variable. A better understanding of the pathophysiology of inflammatory bowel diseases and of the action of anti-TNF alpha is essential to an optimized care. Our hypothesis is that the efficacy of anti-TNF alpha in spondyloarthritis and in inflammatory bowel diseases is at least partly due to its restoring action of homeostasis at the interface between gastrointestinal mucosa and intestinal microbiota, either by primary action on the digestive epithelium, allowing it to regain its control and tolerance functions toward mucosal microbiota, either by direct action on the intestinal microbiota, via an inter-reigns regulation. The main objective of our study is to assess quantitative and qualitative changes in fecal microbiota before (D0) and 3 months after initiation of anti-TNF alpha.

Study Arms (2)
Patients with anti-TNF alpha
EXPERIMENTAL12 spondyloarthritis and 24 inflammatory bowel diseases patients (12 Crohn's disease and 12 ulcerative colitis), in which a first anti-TNF alpha treatment is indicated.
mirror group
ACTIVE COMPARATORA mirror group of 12 spondyloarthritis and 24 inflammatory bowel diseases patients (12 Crohn's disease and 12 ulcerative colitis), in which an "all but anti-TNF alpha or biotherapy" treatment is indicated will be included to distinguish the specific effects on microbiota of anti-TNF alpha.
Interventions
14 ml whole blood for Peripheral blood mononuclear cell (PBMC) and monocytes isolation
food questionnaire on the seven days before the collection
Only for patients with ulcerative colitis (in routine care)
Volatile Organic Compounds (VOCs) profile obtained by mass spectrometry
Eligibility Criteria
You may qualify if:
- Patients aged over 18 years
- Patients with the following conditions :

- Crohn's disease (CD) fulfilling the ECCO criteria
- Axial or peripheral spondyloarthritis (SpA) fulfilling the Assessment of SpondyloArthritis (ASAS) criteria
- Patients naïve to anti-TNF alpha, justifying the initiation of an anti-TNF alpha treatment according to current guidelines (ECCO Inflammatory bowel disease (IBD) recommendations, the recommendations of the French Society of Rheumatology for SpA)
- Patients agreeing to sign the informed consent
