Systemic vasculitis: one year in review 2025

Abstract

Systemic vasculitides encompass a spectrum of inflammatory disorders affecting several organs and districts, with significant implications for morbidity and mortality. This annual review provides an updated overview of key advancements in vasculitis research, including emerging biomarkers, novel insights into pathogenesis, and therapeutic innovations in both large and small vessel vasculitis. Particular attention is given to emerging concepts, including the role of cellular senescence and stromal cells in vascular inflammation, the expanding spectrum of single-organ vasculitis, and the growing recognition of VEXAS syndrome as a vasculitis-related entity.
