New Take Tens on Psoriatic Arthritis

IPC Councilor Anna Lopez Ferrer, MD, PhD, reviews PURE-4, a four-item tool that helps dermatologists screen psoriasis patients for psoriatic arthritis (PsA) risk. She traces its evolution across three studies (2018–2026) into a validated predictor of early PsA.

IPC Councilor André Lucas Ribeiro, MD, reframes PsA as a slow transition from psoriasis, not a sudden event, opening the door to disease interception. He outlines the steps needed to get there, from harmonizing definitions to reducing inflammatory burden.
