A EUVAS-sponsored expert panel of 37 specialists across rheumatology, nephrology, dermatology and pathology has published evidence-based guidelines for adult-onset IgA vasculitis (IgAV), which behaves very differently in adults compared to usually self-limited childhood form.

A new study may add fuel to the fire already burning around avacopan (Tavneos), approved in 2021 to treat anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV), which the FDA wants drugmaker Amgen to pull from the U.S. market.

This review article addresses the recognition, prevention and management of glucocorticoid toxicity in rheumatic patients.

High fever, strange rashes, scary labs often lead to a consideration of Still's disease (AOSD or systemic JIA). Yet the dramatic onset of a systemic disorder may overlap with another, and possibly as rare, systemic disorder that should not be misdiagnosed or mistreated. A current case review by Zhu et al. presents six cases initially diagnosed as systemic JIA, teaching several important lessons.

RA confers a 50–100% excess risk of venous thromboembolism (VTE) compared with the general population, with adjusted hazard/odds ratios ranging from 1.3–2.2 across large cohort studies (Vojinovic, Askling, Antovic; Rheumatology, 2026).

Shoulder pain affects 16% of adults annually and is the third most common musculoskeletal presentation in primary care. This new review reframes the diagnostic and therapeutic approach, moving away from pathoanatomic labels (rotator cuff tendinopathy, impingement, bursitis) toward the umbrella term subacromial pain, since structural findings on imaging correlate poorly with symptoms and are common in asymptomatic people.

Today Argenx announced the results of their Phase 3 "ALKIVIA" study; demonstrating efficacy and safety of subcutaneous efgartigimod for Idiopathic Inflammatory Myopathy (IIM, AKA inflammatory myositis).

A review article assesses and integrates mechanistic, imaging, and clinical evidence to examine whether effective treatment of psoriasis may modify the future risk of psoriatic arthritis (PsA).

The phase 3 ZEUS trial (published in JAMA Dec. 2025)  tested the IL-6 ligand inhibitor ziltivekimab in over 6,000 patients with atherosclerotic cardiovascular disease, chronic kidney disease, and elevated hsCRP—a population enriched for an inflammatory driver of risk.

Patients from wealthier European countries tend to start treatment with biologics earlier but also stop or switch treatment earlier. They also experience lower disease activity at treatment start than patients in middle- and low-income countries.

POETYK PsA-1 trial tested the disease modifying efficacy of deucravacitinib, a tyrosine kinase 2 (TYK2) inhibitor, in psoriatic arthritis (PsA) patients and was shown to be superior vs to placebo for clinical responses, patient-reported outcomes, and structural damage inhibition in PsA.

Eosinophilic granulomatosis with polyangiitis (EGPA) has long been managed by extrapolating results from microscopic polyangiitis and granulomatosis with polyangiitis clinical trials. But new insights into EGPA's has lead to advances in therapy and new treatment paradigms.
