Spondyloarthritis & psoriatic arthritis
Evaluation of the agreement between the ACR 1990 fibromyalgia tender points and an enthesitis score in patients with axial spondyloarthritis
Authors' conclusion
These results suggest a significant overlap between both scores in patients with axSpA, including in those without concomitant FM.
Study context
- Population
- Patients with axial spondyloarthritis (axSpA) (rheumatologist diagnosis) with an indication to start a TNF blocker; screened for FM by the FiRST questionnaire202 (38%) with FM
- Participants
- 526 patients
- Exposure
- MASES enthesitis score vs ACR 1990 fibromyalgia tender points
- Outcome
- Agreement between MASES and ACR 1990 TPs by intraclass correlation coefficient (ICC), also stratified by presence/absence of FM (FiRST)
Methodological detailsancillary analysis of the Predict-SpA study, A physician assessed 31 anatomically described sites in random order, blinded to which instrument each site belonged
