The development of Assessment of SpondyloArthritis international Society classification criteria for axial spondyloarthritis (part II): validation and final selection
The new ASAS classification criteria for axial SpA can reliably classify patients for clinical studies and may help rheumatologists in clinical practice in diagnosing axial spondyloarthritis in those with chronic back pain.
The development of Assessment of SpondyloArthritis international Society classification criteria for axial spondyloarthritis (part I): classification of paper patients by expert opinion including
The ASAS group has developed candidate criteria for the classification of axial SpA that include patients without radiographic sacroiliitis, and the candidate criteria need to be validated in an independent international study.
ASAS/EULAR recommendations for the management of ankylosing spondylitis
Ten key recommendations for the treatment of ankylosing spondylitis were developed and assessed using a combination of research based evidence and expert consensus.
How to diagnose axial spondyloarthritis early.
This approach can help clinicians to diagnose with a high degree of confidence axial SpA at an early stage in patients with IBP who lack radiographic sacroiliitis.
New criteria for inflammatory back pain in patients with chronic back pain: a real patient exercise by experts from the Assessment of SpondyloArthritis international Society (ASAS)
A new approach with real patients defines a set of IBP definition criteria using overall expert judgement on IBP as the gold standard, which are robust, easy to apply and have good face validity.
Entheses and enthesitis: a histopathologic review and relevance to spondyloarthritides
In these complex pathologic conditions, no single abnormality can thus far be designated as a unique hallmark, and no single immunologic target can be identified.
Enthesitis in spondyloarthropathy.
The importance of enthesitis as a skeletal phenomenon in spondyloarthropathies has gained further support from transgenic models in which either tumor necrosis factor-alpha or bone morphogenetic protein-6 overexpression result in entheseal-associated polyarthropathy.
The SAPHO syndrome.
An acronym, the SAPHO syndrome (which stands for Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis) is proposed for this group of diseases because of the similarity of musculoskeletal manifestations in patients with severe acne and pUSTulosis.
Selection of instruments in the core set for DC-ART, SMARD, physical therapy, and clinical record keeping in ankylosing spondylitis. Progress report of the ASAS Working Group. Assessments in
To select specific instruments for each domain of the core set for endpoints in ankylosing spondylitis (AS), we gathered all instruments described in the literature to assess the domains chosen as
Scientific contributions of ankylosing spondylitis patient advocacy groups.
The speed at which spinal ankylosis progresses is slower in female patients, but women are in a significantly worse situation than men in terms of pain and the need for drug therapy, even though the women in the German Ankylosing Spondylitis Society sample are, on average, younger than the men and have a shorter average disease duration.
