Comparison of radiographic spinal changes and their progression in patients with axial spondyloarthritis vs. psoriatic arthritis with inflammatory axial involvement.

ABSTRACT:

Background

Psoriatic arthritis with inflammatory axial involvement (PsA-ax) and axial spondyloarthritis (axSpA) are distinct entities within the spectrum of spondyloarthritides. Despite overlapping clinical and imaging features, the extent and pattern of radiographic spinal progression in PsA-ax relative to axSpA remain insufficiently characterized.

Objective

To describe and analyse differences in radiographic spinal progression between axSpA and PsA-ax.

Methods

In this retrospective cohort study, 246 patients (axSpA: n=172; PsA-ax: n=74) with lateral radiographs of the cervical, thoracic, and/or lumbar spine were included. Radiographic progression was quantified using the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). An adjusted linear mixed-effects mo
