Arthritis is a recognized extraintestinal manifestation of several illnesses and conditions, including inflammatory bowel disease (IBD), bacterial infections of the gut, gluten sensitive enteropathy (celiac disease), various parasitic infections, and pseudomembranous colitis; and following intestinal bypass surgery. Other illnesses have a propensity for causing inflammation of joints and the gut. Examples discussed in this review include Behçet’s and Whipple's diseases.
The clinical features of arthritis associated with IBD are discussed in detail here, along with the treatment for synovitis in patients with Crohn's disease and ulcerative colitis. The pathogenesis and treatment of IBD are discussed separately. (See "Mechanisms for the induction of rheumatic symptoms by gastrointestinal disease" and "Immune and microbial mechanisms in the pathogenesis of inflammatory bowel disease" and "Overview of the medical management of mild to moderate Crohn disease in adults" and "Management of severe ulcerative colitis".)
Therapy for reactive arthritis (formerly called Reiter syndrome) and Behçet’s and Whipple's diseases are also discussed separately. (See "Reactive arthritis (formerly Reiter syndrome)", section on 'Treatment' and "Treatment of Behçet’s disease" and "Whipple's disease", section on 'Treatment'.)
PREVALENCE AND ASSOCIATED DISEASES
Arthritis occurs in 6 to 46 percent of patients with inflammatory bowel disease (IBD) [1-7]. Arthritis is somewhat more likely to occur in patients with large-bowel disease and in those patients with complications such as abscesses, pseudomembranous polyposis, perianal disease, massive hemorrhage, erythema nodosum, stomatitis, uveitis, and pyoderma gangrenosum. Among patients with Crohn's disease, those with colonic involvement are at higher risk of developing synovitis than those with isolated small bowel disease. Males and females are affected equally. Both children and adults are at risk for this complication of IBD. In addition, subclinical gut inflammation, documented by endoscopy, has been described in up to two-thirds of patients with spondyloarthropathies .
ULCERATIVE COLITIS AND CROHN'S DISEASE
Ulcerative colitis and regional enteritis (Crohn's disease) are the most frequently encountered types of idiopathic inflammatory bowel disease (IBD) that are associated with arthritis or spondylitis and are discussed first. Other disorders associated with joint pain and/or inflammation are discussed later. (See 'Other diseases with bowel and joint involvement' below.)
