Key clinical point: Ultrasound detected active enthesitis and synovitis in a non-negligible proportion of patients with psoriatic arthritis (PsA) who achieved remission or low disease activity with biological or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARD).
Major finding: Despite achieving the Disease Activity Index for Psoriatic Arthritis (DAPSA) treatment target, 21.6% patients had at least one painful enthesis on clinical examination. Ultrasound showed evidence of active enthesitis in 19.6% and active synovitis in 15.7% patients.
Study details: This cross-sectional study included 51 patients with PsA who met the DAPSA treatment target after at least 6 months of therapy with b/tsDMARD and underwent bilateral ultrasound and clinical examination of entheses and joints.
Disclosures: This study did not receive any external funding. The authors declared no conflicts of interests.
