  • The condition impacts up to 2% of white populations in the EU and North America1
  • Men are 2.5 times more likely to be affected by any form of SpA than women1
  • SpA is closely related to the presence of the HLA-B27 gene2

Terminology

  • · Spondyloarthritides is the plural for Spondyloarthritis - a group of inflammatory arthritic diseases sharing common clinical and genetic features1
  • · SpAs are characterized by the following:1
    • Axial SpA – involving inflammation of the spine or sacroiliac joints. This includes the most severe form - ankylosing spondylitis (AS)2
    • Peripheral SpA – characterised by peripheral arthritis, enthesitis (heel pain) and dactylitis (swelling of the finger)1

  • · Men are 2.5 times more likely to be affected by women1
  • AS is the most frequent and severe sub-type, affecting 0.3–0.5% of people2

Risk Factors

  • Carriers of the HLA-B27 gene which is present in more than 90% of AS patients2
  • Psoriatic skin lesions2
  • Colitis due to inflammatory bowel disease (IBD)2

Symptoms

  • Inflammatory back pain lasting more than three months1
  • Morning stiffness in the spine, lasting more than 30 minutes1
  • Alternating buttock pain1
  • Arthritis2
  • Eye inflammation (uveitis)3
  • Fatigue3

  • Pharmacotherapy:3
    • Non-steroidal anti-inflammatory drugs (NSAIDs)
    • Steroids
    • Disease-modifying anti-rheumatic drugs (DMARDs)
    • Biologic drugs
  • Non-medicinal:3
    • Ice packs and heat pads to relieve joint pain and swelling
    • Use of a transcutaneous electrical nerve stimulation machine (TENS)
    • A healthy diet
    • Exercise such as swimming to relax joints
