Erosive polyarthritis in Crohn's disease. Report of a case.
Erosive polyarthritis in Crohn's disease is rare and raises diagnostic and pathophysiological problems. A case with destructive lesions of the shoulders and hips is reported in a 43-year-old woman with a 26-year history of Crohn's disease. Ankylosis of the spine and hips, motion range limitation of the shoulders and wrists, and boutonnière deformity of the third finger of the right hand were present. Tests were negative for rheumatoid factor and the HLA-B27 antigen. Plain radiographs showed a triple rail pattern at the spine; synostosis of the hips; and destructive lesions of the shoulders, wrists, tarsal bones, and third proximal interphalangeal joint of the right hand. Glucocorticoid therapy was effective in suppressing the bowel symptom flares but only partially improved the joint symptoms, whose treatment relied mainly on nonsteroidal antiinflammatory agents and rehabilitation therapy. Erosive arthritis in Crohn's disease is frequently monoarticular, with the hip being the most common target. It can complicate a spondylarthropathy or reveal granulomatous synovitis. Polyarticular forms pose difficult diagnostic and therapeutic challenges and add to the disability caused by the bowel disease. The potential role of genetic factors remains to be studied.
