The prevalence and incidence of peripheral arthritis in patients with inflammatory bowel disease, a prospective
1Department of Rheumatology, Østfold Central Hospital, N-1701 Sarpsborg, Norway.
Objectives:
To estimate the occurrence of peripheral arthritis (PA) 6 yr after diagnosis of inflammatory bowel disease (IBD).
Methods:
In a population-based cohort of 654 patients with a definite diagnosis of IBD, 521 patients (80%) were clinically examined by a rheumatologist 6 yr after IBD diagnosis.
Results:
PA related to IBD (PAIBD) was detected at examination in four patients (point prevalence 0.8%). If the patients' own reports of PA were accepted, 12% of the cases had developed such manifestations. The striking difference may be explained by the nature of PAIBD exhibiting a short-lasting, self-limiting, non-destructive course and by possible differences in the validity of both methods of ascertainment.
Conclusion:
Our results indicate that PAIBD occurs in a considerable number of IBD patients during the first years after diagnosis, but the point prevalence of PAIBD is low.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
