Patients with Crohn's disease, a type of inflammatory bowel disease (IBD) that causes abdominal pain and diarrhea, can also experience joint pain. In Crohn's disease, which affects about 800,000 Americans, the immune system can attack not only the bowels, but the musculoskeletal system as well, leading to spondyloarthritis, a painful condition that affects the spine and joints. Now new research, published in Science Translational Medicine, helps explain the connection between these seemingly unrelated symptoms, and could help physicians identify Crohn's disease patients who are more likely to develop spondyloarthritis, enabling them to prescribe more effective therapies for both conditions.
