Topography of entheseal lesions on ultrasound: a comparative study between axial spondyloarthritis, psoriatic arthritis and healthy controls.

ABSTRACT:

Objectives

To determine which anatomical sites and which ultrasonographic entheseal lesions are best able to discriminate between spondyloarthritis (SpA) patients and healthy controls (HC).

Methods

We included patients with psoriatic arthritis (PsA) and axial SpA (axSpA), from six Swiss hospital outpatient clinics, as well as HC. Participants completed quality of life and physical activity questionnaires and underwent a clinical examination of both joints and entheses, followed by a detailed musculoskeletal ultrasound examination including nine entheseal sites bilaterally. Entheses were scored according to the Outcome Measures in Rheumatology criteria, with an additional evaluation of bursae and power Doppler (PD) in the 2-5 mm zone.

Results

Overall, 121 participants
