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

EXPERIMENTAL

12 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.

Other: blood sampleOther: stool samplesOther: food questionnaireOther: colonoscopyOther: VOCs profile

mirror group

ACTIVE COMPARATOR

A 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.
