Background
Joint pain is common in subjects affected by Inflammatory bowel disease (IBD) and is linked to several factors including spondyloarthritis (SpA), drug therapy, concomitant osteoarthritis and fibromyalgia (FM). The primary aim of this study was to estimate the prevalence of primary FM and concomitant FM and SpA in a cohort of IBD patients. The secondary aim was to assess the impact of FM on clinimetric scores and ultrasonographic features.
Methods
Consecutive cases with IBD attending two IBD Units were assessed by a rheumatologist for ASAS criteria for SpA or the 2010 ACR criteria for FM. The rheumatological assessment included a 66 swollen joint count (SJC) and 68 tender joint count (TJC), Maastricht Ankylosing Spondylitis Score (MASES), Leeds Enthesitis Index (LEI) and the FM tender points examination, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI). One hundred and fifty-eight patients seen at Reggio Emilia centre underwent US entheseal examination. MRI and HLA-B27 determination were requested if needed for diagnostic confirmation.
Results
301 patients were enrolled with 148 completing the clinical and imaging/laboratory assessment if requested for diagnostic purpose. A total of 37 IBD patients (12%) met the ACR criteria for FM: 27 patients (9%) presented the criteria for primary FM and 10 patients (3.3%) presented FM and SpA. Patients who met FM criteria were mostly female (81%,
Conclusion
FM is common among IBD patients and more prevalent in females and patients aged ≥ 45 years old. In this subgroup of patients SpA disease activity indices performed poorly for distinguishing patients with disease activity from those with functional impairment. On the contrary, US examination showed a promising discriminating capacity in SpA patients.
