Psoriatic arthritis (PsA) affects approximately 30% of patients with psoriasis (PsO), and diagnostic delays are associated with worse prognosis, making early detection crucial. At EULAR 2025, several studies highlighted progress in prediction strategies. Here's my review of three of them.

As earlier diagnosis and treatment of rheumatoid arthritis (RA) have resulted in greatly improved clinical outcomes, the focus of current research has now shifted to preventing the development of RA altogether. At EULAR 2025, several oral presentations explored this objective, highlighting data from three key prevention trials: APIPRA, ARIAA, and TREAT EARLIER. Each trial targeted individuals considered to be “at-risk” for developing RA, investigating whether early immunomodulatory interventions could delay or prevent progression to classifiable RA.

At EULAR 2025, there have been new developments in imaging in PsA.
