Psoriatic arthritis develops in approximately 20 to 30 per cent of patients with psoriasis, yet predicting which patients will make the transition and when, has remained one of the most clinically challenging questions in rheumatology. A study presented at EULAR 2026 provides the most granular ultrasound characterisation yet of the journey from psoriasis, through subclinical disease, to early clinical PsA. The study identifies the specific

MAS, the most severe complication of Still’s disease, is increasingly recognized as a cytokine-driven hyperinflammatory state centered on interferon gamma (IFNγ). Therapeutic advances presented at EULAR 2026 demonstrate both consolidation of established pathways and expansion into novel biologic strategies.

The last day in London was exciting as both the Late-Breaking abstracts and new EULAR guidelines were presented. Guidelines presented addressed several significant unmet need areas including PMR, GCA, Takayasu’s arteritis, Vaccinations in Rheumatic patients, Imaging in spondyloarthritis and classification criteria for the Anti-Synthetase Syndrome. Here are but a few of my favorites from a list of many quality sessions.

B-cell targeting has moved to the centre of IgG4-related disease treatment, with inebilizumab, a CD19 depleter, as the recent benchmark. At EULAR 2026, INDIGO tested whether the disease can be controlled by switching B cells off rather than depleting them.

Systemic sclerosis is a rare connective tissue disorder characterised by autoimmune features with vascular manifestations, causing fibrosis of the skin and internal organs. EULAR is focused on systemic sclerosis as the rheumatic disease with the highest morbidity and mortality. New data presented at the EULAR 2026 Congress underscore key complications, and offer hope for a possible new therapeutic strategy.

CD19-directed CAR T-cell therapy has rapidly moved into autoimmune disease, driven in large part by striking reports in SLE, where sustained drug-free remission has raised the possibility of a true immune reset. In RA, where multiple effective therapeutic classes already exist, the relevance of such deep immune interventions remains uncertain.

ASAS and the SPARTAN have updated their key classification criteria for axial SpA (axSpA). EULAR has also recently revised their recommendations on the role of imaging in the diagnosis and clinical management of spondyloarthritis (SpA). Both were presented at the EULAR 2026 annual Congress in London.

Day 3 was an interesting mix of posters, oral presentations, and review sessions on many practical subjects like osteoarthritis, large vessel vasculitis, systemic sclerosis, and pregnancy. Here are a few of my recommended abstracts from Friday at EULAR 2026.

Idiopathic inflammatory myopathies (IIM) are a heterogenous group of autoimmune conditions with substantial morbidity. EULAR in collaboration with the American College of Rheumatology (ACR) introduced classification criteria for the major subgroups in 2017,1 but there is a need for contemporary real-world data to understand the burden – and well as new ways of assessing disease activity.

Day two at EULAR 2026 was jammed with sessions on advances in immune checkpoint inhhbitors (and irAEs), Lupus, Scleroderma, RA and IgG4 related disease.  Here are a few of my favorites from Day 2. 

RA-ILD remains one of the most serious extra-articular manifestations of RA, contributing substantially to morbidity and mortality. Two abstracts presented at EULAR 2026 add important insights into identifying patients at risk for RA-ILD and understanding the genetic mechanisms that may underpin disease development.

Presented at EULAR 2026 London, Brepocitinib dual TYK2/JAK1 inhibitor with successful Phase 3 VALOR trial demonstrating significant improvement in skin and muscle symptoms in dermatomyositis (DM).

Glucocorticoids are the cornerstone of initial vasculitis treatment, used to rapidly control inflammation and protect vital organs. EULAR has recommendations that cover glucocorticoid use in ANCA associated vasculitides (AAV) and large vessel vasculitis, including giant cell arteritis (GCA).1,2 But the evidence base continues to grow about their use – especially over the long term.

EULAR works with the network of national organisations of People with Arthritis/Rheumatism in Europe (PARE) to ensure the voices of people with RMD are heard and have influence – creating powerful alliances that make a real difference. Artificial intelligence is another potential ally in that fight. At the EULAR 2026 Congress in London, work was presented from three PARE initiatives that showcase how digital tools can be used in treatment

People with rheumatic and musculoskeletal diseases (RMD) are at risk of a number of comorbidities, from cardiovascular diseases to cognitive impairment and fractures. The 2026 EULAR Congress showcased new data and ideas around various comorbidities and drug safety issues in people with an RMD – highlighting the need for integrated care. Here are five abstracts to consider.
