Patients with chronic inflammatory diseases (CID) followed in gastroenterology, dermatology and rheumatology have physiopathological, epidemiological and therapeutic focal points. The pathologies concerned are inflammatory bowel diseases (IBD - Crohn's disease [MC] and ulcerative colitis [RCH]), chronic inflammatory skin diseases (psoriasis or Verneuil's disease) and chronic inflammatory rheumatic diseases (rheumatoid arthritis [RA] and spondyloarthritis [SpA] including psoriatic arthritis [PsA]). Presenting one of these diseases is associated with a higher risk of having a second inflammatory pathology, whether the latter is ophthalmological, dermatological, rheumatological or gastroenterological. An association of extra-articular manifestations is observed in 10 to 30% of patients with SpA, and an association of extra-intestinal manifestations is observed in approximately 30% of patients with IBD. No common database for chronic systemic inflammatory diseases currently exists in France.
