Axial disease in psoriatic arthritis

Curr Rheumatol Rep. 2007 Dec;9(6):455-60. doi: 10.1007/s11926-007-0074-2.


The definition of axial disease in psoriatic arthritis has varied from isolated unilateral grade 2 sacroiliitis to criteria similar to those used for ankylosing spondylitis. Depending on the definition used, the prevalence of axial disease varies from 25% to 70% of patients with psoriatic arthritis. This article reviews the prevalence, clinical and radiologic features, pathogenesis, prognosis, and treatment of psoriatic spondylitis.
