Physicians perceptions of the spondyloarthropathies are changing. Ankylosing spondylitis (AS), the prototype of this group, has traditionally been considered a rare disease with few therapeutic options. In addition, diagnosis is difficult, sometimes delayed for decades, mainly owing to the lack of sensitivity of the traditional imaging method, radiography, to detect the hallmark of AS, sacroiliitis. Also, the widespread perception of these diseases as "innocuous" or having a good outcome has hampered the development of protocols for defining early disease and identifying those patients who would benefit from early treatment.
It is now clear that these assumptions are incorrect. Ankylosing spondylitis is more common than previously estimated, with some studies suggesting a prevalence as high as 1%.1 Importantly it affects people at a time when they are economically active (most commonly in the third decade), and the disease has a major impact on a persons ability to work.
