Toward a Sonographic Composite Index for Diagnosis in Psoriatic Arthritis: Highlights From the GRAPPA Ultrasound Workshop

The ability to visualize musculoskeletal structures with high-resolution ultrasound is an asset to understanding the complexity of psoriatic arthritis (PsA). During the 2021 Annual Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) meeting, 3 topics were presented and discussed in the ultrasound workshop: (1) the progress on the Diagnostic Ultrasound Enthesitis Tool (DUET) project;(2) the sonographic evaluation of joints in PsA GRAPPA joint project; and (3) extrasynovial lesions in PsA. The ultrasound group aims to develop sonographic, tools that are feasible and can be used in standard care to diagnose PsA early. The discussions around these topics will shape the group's work toward developing acomposite index to diagnose PsA early.

Automated summary

The use of high-resolution ultrasound is crucial for understanding the complexity of psoriatic arthritis. Recent discussions at the GRAPPA meeting focused on developing ultrasound tools for diagnosis, sonographic evaluation of joints, and extrasynovial lesions in psoriatic arthritis.
