What Is Axial Spondyloarthritis?
PRACTICE AID
Axial Spondyloarthritis (axSpA)
• A painful chronic inflammatory disease that primarily affects the spine and sacroiliac joints
(SIJs)1
• Leading symptom: inflammatory back pain that improves with exercise but not with rest1
• Disease onset: usually before age of 45 years3,4
• Prevalence: 0.2%-1.4% of adults have axSpA, which is similar to RA3,5,6; equally prevalent
in both men and women4,7
Often MRI shows
evidence of
inflammation on SIJs
and spine2
AS is most
prevalent in men
(65%)9,10
No definitive SIJ
structural damage
on x-ray2
nr-axSpA is most
prevalent in women
(66%)9,10
10%-12% of patients with nr-axSpA
progress to AS in 2 years9,11
Definitive SIJ
structural damage
on x-ray2
~60%-70% of patients
with AS develop
bony growths that
lead to vertebra
fusion1,8
Nonradiographic axSpA
(nr-axSpA)
The presence or absence of structural
damage to SIJs on x-ray differentiates
nr-axSpA from AS2
Radiographic axSpA
(ankylosing spondylitis [AS])

Fatigue and

• Uveitis: eye inflammation
• Enthesitis: inflammation
of the points of insertion
of tendons and ligaments
into bone
• Peripheral arthritis
• Psoriasis: skin disease
• IBD: chronic inflammation
of the digestive tract
• Dactylitis: inflammation
of the fingers or toes
Patients with nr-axSpA and AS
share common clinical features 2,8,11-13
and experience a significant
and similar disease burden2

Diagnostic Algorithm for
Axial Spondyloarthritis (axSpA)1
PRACTICE AID
ESR: erythrocyte sedimentation rate; HLA-B27: human leukocyte antigen B27; IBP: inflammatory back pain.

4. ASAS-Endorsed Recommendation for PCPs on Early
Referral of Patients With Suspected axSpA1
a
Any set of criteria, preferably ASAS definition of inflammatory back pain. b
Only if imaging is available, not recommended as routine screening parameter. c
According to the definition applied in the classification criteria for axSpA.
d
C-reactive protein serum concentration or erythrocyte sedimentation rate above upper normal limit after exclusion of other causes for elevation.
ASAS: Assessment of Spondyloarthritis International Society; axSpA: axial spondyloarthritis; HLA-B27: human leukocyte antigen B27.

• Inflammatory back paina
• HLA-B27 positivity
• Sacroiliitis on imaging, if available (x-ray or MRI)b
• Peripheral manifestations (arthritis, enthesitis, dactylitis)c
• Extra-articular manifestations (psoriasis, IBD, uveitis)c
• Positive family history for spondyloarthritisc
• Good response to NSAIDsc
• Elevated acute phase reactantsd
