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.
