Psoriatic arthritis

Imaging and Early Detection in Psoriatic Arthritis At EULAR 2025, there have been new developments in imaging in PsA. Two key poster presentations (POS0104 and OP0179) provide important insights into the role of imaging in the management and early detection of psoriatic https://t.co/41fgXj5WnN

Predicting Psoriatic Arthritis in Psoriasis: How Close Are We?

Nelly Ziade

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.

Methotrexate and Leflunomide combination in RA/PsA: Is it safe?

Aurelie Najm, MD, PhD

I asked the EULAR twitter sphere how they feel about combination of methotrexate (MTX) and leflunomide (LEF). The opinions are differing so far, with 50% reporting prescribing this combination often while 50% are worried of side effects. Several abstracts presented this year are providing

From Domains to Decisions: Personalizing PsA Care with Data

Jiha Lee, MD

At EULAR 2025, Dr. Laura Coates (Oxford) took the plenary stage to reframe how we think about treating psoriatic arthritis. The message was clear: in 2025, PsA treatment is no longer about following a linear algorithm; it’s about understanding the unique constellation of domains, comorbidities,
