Ankylosing spondylitis (AS) is a type of arthritis in which there is a long-term inflammation of the joints of the spine.[2] Typically the joints where the spine joins the pelvis are also affected.[2] Occasionally other joints such as the shoulders or hips are involved.[2] Eye and bowel problems may also occur.[2] Back pain is a characteristic symptom of AS, and it often comes and goes.[2] Stiffness of the affected joints generally worsens over time.[2][4]
Although the cause of ankylosing spondylitis is unknown, it is believed to involve a combination of genetic and environmental factors.[2] More than 90% of those affected in the UK have a specific human leukocyte antigen known as the HLA-B27 antigen.[5] The underlying mechanism is believed to be autoimmune or autoinflammatory.[6] Diagnosis is typically based on the symptoms with support from medical imaging and blood tests.[2] AS is a type of seronegative spondyloarthropathy, meaning that tests show no presence of rheumatoid factor (RF) antibodies.[2] It is also within a broader category known as axial spondyloarthritis.[7]
There is no cure for ankylosing spondylitis.[2] Treatments may improve symptoms and prevent worsening.[2] This may include medication, exercise, and surgery.[2] Medications used include NSAIDs, steroids, DMARDs such as sulfasalazine, and biologic agents such as TNF inhibitors.[2]
Between 0.1% and 1.8% of people are affected.[3] Onset is typically in young adults.[2] Males are more often affected than females.[2] The condition was first fully described in the late 1600s by Bernard Connor, but skeletons with ankylosing spondylitis are found in Egyptian mummies.[8] The word is from Greek ankylos meaning to unite or grow together, spondylos meaning vertebra, and -itis meaning inflammation.[2]
