Synovio-entheseal inflammation and the tipping point from PsO to PsA

Save

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 imaging features that distinguish patients whose arthralgia is progressing toward arthritis from those who remain stable.

Lessons on Non-adherence

Save

Dr. Sun et al. from Duke University presented abstract POS0692 during one of the poster sessions entitled, “Lupus patients with concurrent inflammatory activity and symptom burdens have the lowest medication adherence and experience distinct adherence barriers.” They evaluated differences in self-reported medication adherence and reasons for nonadherence across Type 1 & 2 SLE classification groups, with a prespecified focus on comparing the Mixed Activity group to all other groups.

Seeing more or seeing too much? Ultrasound vs MRI in preclinical RA

Imaging in the preclinical phase of RA is moving fast—arguably faster than our ability to interpret what we are actually seeing.

What’s New in Macrophage Activation Syndrome Therapeutics

Save

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.

Hot topic: menopause and inflammatory arthritis outcomes in RA and PsA

Save

Across EULAR 2026 abstracts this year and presented in a session called “this is a woman’s world”, strong signals are emerging that the menopausal transition is associated with changes in disease phenotype, disease activity, and treatment response in both RA and PsA.

New Oral Option for axSpA: Filgotinib for Radiographic and Non-Radiographic Disease

Save

The Janus kinase inhibitor (JAKi) class has been increasingly used in the management of axial spondyloarthritis (axSpA) over the past five years, offering effective oral alternatives to injectable biologics. But are all JAK inhibitors the same?

Day 4 EULAR Report

The last day in London was exciting as both the Late-Breaking abstracts and new EULAR guidelines were presented.

INDIGO: Switching B Cells Off, Not Out, in IgG4-Related Disease

Save

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.

Obinutuzumab drives histologic remission in lupus nephritis

Save

At EULAR 2026, investigators are presenting perhaps the most biologically compelling data yet from the REGENCY trial, with evidence that obinutuzumab induces deep intrarenal B-cell depletion alongside markedly higher rates of histological remission.

RA-ILD in the Age of Treat-to-Target: Put the Probe on the Chest

Save

At EULAR 2026, speakers of the session “Catching Your Breath: Unravelling RA Associated Interstitial Lung Disease (ILD)” noted RA-ILD is one of the few outcomes not improving in the biologic era. Three abstracts reinforce that message and make the case for a practical, low-cost screening tool that is already in most rheumatologists’ hands.

Improving Understanding in SSc

Save

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.

Immune Dimming or Immune Reset in RA: How Far Should We Go?

Save

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.
