Sonographic enthesitis associated with sonographic synovitis and tenosynovitis in PsA

Key clinical point: Sonographic enthesitis showed strong association with sonographic synovitis and tenosynovitis in patients with psoriatic arthritis (PsA), suggesting the clinical significance of sonographic enthesitis as a potential marker for inflammation in other musculoskeletal domains.

Major finding: Sonographic enthesitis was significantly associated with sonographic synovitis (β 0.19; P  =  .004) and sonographic tenosynovitis (β 0.1; P  =  .003) and showed strong correlation with patient-reported outcomes, such as Health Assessment Questionnaire (P  =  .003), morning stiffness (P  =  .002), and others.

Study details: This study prospectively recruited 158 patients with PsA who underwent sonographic assessment of 52 joints, 40 tendons, and 14 entheses points along with clinical evaluation.
