Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose: Estimates of axial involvement in PsA vary from 25% to 70% depending on the inclusion criteria. Three sets of criteria are available for defining inflammatory back pain (IBP) in Ankylosing Spondylitis (AS): Calin, Rudwaleit and ASAS criteria. We aimed to determine whether these criteria are useful screening tools for axial involvement in PsA and to describe the clinical features in PsA patients with IBP, mechanical back pain (MBP), no Back Pain (BP) and silent BP.
Conclusion: Patients with PsA report less back pain than AS patients. The low level of agreement between physician assessment and radiological presence of axial PsA indicates that we should consider axial imaging in all patients with PsA regardless of the presence of the nature of BP.
