Inflammatory bowel diseases (IBD), such as Crohn disease and ulcerative colitis, are linked to arthritis through a subset of conditions known as spondyloarthropathies. This complication affects as many as 20 percent of patients with IBD.1

The relationship between these conditions is characterized by the following:

Clinical Presentation: While arthritis associated with IBD typically affects the lower extremities, up to 20 percent of these cases present with symptoms identical to ankylosing spondylitis, which involves inflammation of the spine and sacroiliac joints.12
Exacerbation Patterns: Joint inflammation is usually linked to the activity of the underlying bowel disease. Arthritis symptoms are typically exacerbated in conjunction with IBD flare-ups and generally persist for several weeks after the bowel inflammation has subsided.1

Unlike rheumatoid arthritis, these IBD-associated arthritic conditions are not linked to elevated levels of serum rheumatoid factor.12
