Highlights from today included presentations on imaging in vasculitis, a debate on whether to treat high risk pre-clinical RA, and EULAR Recommendations on a) Treatment of interstitial lung disease (ILD); b) Physical Activity in people with arthritis; and c) EULAR disease activity score for antiphospholipid syndrome and d) the management of SLE nephritis. Below are a few others that caught my eye today.

At a EULAR 2025 session titled “What makes ‘Difficult-to-treat RA’ so difficult to treat? And what can we do?”, Drs. Paula David and Dennis McGonagle introduced the emerging concept of polyrefractory rheumatoid arthritis (RA), a term now being used to describe a subset of patients who have failed to respond to five or more biologic or targeted synthetic DMARDs. This new classification, derived from recent multinational registry data, represents a significant step in refining our understanding and management of the most treatment-resistant forms of RA.

New work presented at the 2025 annual EULAR congress in Barcelona focuses on the recombinant zoster vaccine (RZV), which contains recombinant glycoprotein E – the major target of CD4+T-cells.
