Key clinical point: Entheseal power Doppler (PD) signal, entheseal bone erosions, and gray scale (GS) joint synovitis were indicative of severe psoriatic arthritis (PsA) in terms of ultrasound (US)-detected joint bone erosion.
Major finding: At least 1 joint bone erosion was found in 45.2% of patients and was associated with PD signal at enthesis (odds ratio [OR] 1.74; P < .01), entheseal bone erosions (OR 3.17; P = .01), and GS synovitis (OR 2.59; P = .02).
Study details: Findings are from a cross-sectional study including 104 patients with PsA.
