Evolution and Treatments of Chronic Inflammatory Systemic Diseases

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.
