TY - JOUR T1 - Therapies for axial disease in psoriatic arthritis. A systematic review. JF - The Journal of Rheumatology JO - J Rheumatol SP - 1431 LP - 1434 VL - 33 IS - 7 AU - Peter Nash Y1 - 2006/07/01 UR - http://www.jrheum.org/content/33/7/1431.abstract N2 - Prevalence rates for axial involvement in psoriatic arthritis (PsA) vary from 40% to 74% depending upon criteria for diagnosis. In the absence of trial evidence to assess axial involvement in PsA, the GRAPPA group, by consensus, has suggested that outcome measures and therapies for axial disease in ankylosing spondylitis (AS) be used. This systematic review addresses the management of axial disease in PsA, and provides treatment recommendations based on the AS literature. ER -
