BACKGROUND: Musculoskeletal symptoms belonging to the spectrum of ‘seronegative spondyloarthritis’ (SpA) are the most common extraintestinal manifestations in patients with inflammatory bowel disease (IBD) and may lead to important disease burden. Patients with suspected SpA should be referred to a rheumatologist for further evaluation.
OBJECTIVE: To investigate the self-reported prevalence of musculoskeletal SpA features in a cohort of patients with IBD and to compare this with actual referrals to a rheumatologist.
METHODS: Consecutive patients with IBD visiting the outpatient clinic were interviewed by a trained research nurse about possible SpA features using a standardized questionnaire regarding the presence or history of inflammatory back pain, peripheral arthritis, enthesitis, dactylitis, psoriasis, uveitis and response to nonsteroidal anti-inflammatory drugs. All patient files were verified for previous visits to a rheumatologist and any rheumatic diagnosis.
RESULTS: At least one musculoskeletal SpA feature was reported by 129 of 350 (36.9%) patients. No significant differences between patients with Crohn disease and ulcerative colitis were found. Review of medical records showed that 66 (51.2%) patients had ever visited a rheumatologist. Axial SpA was diagnosed in 18 (27.3%) patients, peripheral SpA in 20 (30.3%) patients and another rheumatic disorder in 14 (21.2%) patients.
CONCLUSION: Musculoskeletal SpA features are frequently present in patients with IBD. However, a substantial group of patients is not evaluated by a rheumatologist. Gastroenterologists play a key role in early referral of this often debilitating disease.
