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,

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. The abstract describes the tolerability and safety of RZV in patients with inflammatory rheumatic and musculoskeletal diseases (iRMD), showcasing interim data from an ongoing study.

Social determinants of health (SDH), such as socioeconomic status and educational background are factors that are increasingly recognised as critical contributors to health outcomes in chronic diseases. Understanding how certain factors impact different RMDs is important, and new research into this for both systemic lupus erythematosus (SLE) and inflammatory arthritis was presented at the 2025 annual EULAR congress in Barcelona.

Day 2 was a full agenda for those attending EULAR 2025 in Barcelona with sessions on the management of RA, Behcets, Lupus and Hand Osteoarthritis. Clinical overviews on MAS, Ehlers-Danlos, Difficult to treat RA and PsA offered a wide variety of options to rheumatologists. Here are a few interesting presentations from today.
