title: Clinical features of inflammatory joint and spine manifestations in Crohn's disease.
abstract: 167 patients with Crohn's disease were investigated for joint and spine inflammation. Arthritis was observed in 23 patients (14%), sacroiliitis in 24 (14%), and sacroiliitis in combination with arthritis in 11 patients (7%). 15 patients (9%) had ankylosing spondylitis; 9 of them were HLA-B27 positive (60%). A parallel pattern in the course of bowel disease and joint inflammation was observed in 22 out of 34 patients with arthritis (59%). An association between the localization of Crohn's disease and the type of spondylarthritis could not be demonstrated. Patients with arthritis alone developed erythema nodosum (35%) or aphthous stomatitis more often (21%) than patients without spondylarthritis+ (6% and 12%, respectively). Other extra-intestinal manifestations of Crohn's disease did not reveal any association with the development of spondyloarthritis.
