Toward Increasing Precision in the Early Diagnosis of Psoriatic Arthritis.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) ultrasound (US) group continued its focus on developing an early diagnostic tool for psoriatic arthritis (PsA). During the annual US workshop at the GRAPPA 2024 annual meeting in Seattle, Washington, participants reviewed preliminary analyses from the Diagnostic Ultrasound Enthesitis Tool (DUET) study and discussed the initial results of a DUET substudy aimed at defining enthesitis at the single enthesis level. Participants also previewed the ongoing systematic review of articular and periarticular manifestations of PsA, with particular attention to smaller joints. A summary of the 2024 US workshop is given herein.
