Spondyloarthritis & psoriatic arthritis
How good is the agreement between clinical diagnoses and classification criteria fulfilment in axial spondyloarthritis? Results from the SPARTAKUS cohort
Authors' conclusion
We found an overall good concordance between clinical axSpA diagnoses and classification criteria fulfilment, with 83% fulfilling ASAS axSpA and/or mNY criteria.
Study context
- Population
- Patients with prevalent, clinical axial spondyloarthritis (axSpA) attending a rheumatology clinic (SPARTAKUS cohort)consecutively included
- Participants
- 239 patients
- Exposure
- Clinical axSpA diagnoses vs fulfilment of ASAS axSpA and modified New York (mNY) classification criteria; r-axSpA/ankylosing spondylitis (AS) vs nr-axSpA
- r-axSpA/ASn = 141
- nr-axSpAn = 57reference
- Outcome
- Agreement between clinical axSpA diagnoses and fulfilment of ASAS axSpA and mNY classification criteria

Main finding
As reported in the abstract
- Fulfilling ASAS axSpA and/or mNY criteria
- 83%
- Agreement between r-axSpA and mNY criteria fulfilment
- 94%
- PPV of clinical AS diagnosis for mNY criteria fulfilment
- 71%
- PPV of u-axSpA diagnosis for nr-axSpA criteria fulfilment

Observational data: associations, not effects.
Further findings
Disease/health status, r-axSpA/AS vs nr-axSpA
- r-axSpA/AS patients were older, more often men, and had longer disease duration, more uveitis and worse spinal mobility than nr-axSpA
- nr-axSpA patients had more enthesitis and dactylitis
