Treatment‐driven peripheral blood transcriptomic remodelling and baseline predictors of ESSDAI and STAR response to B‐cell therapy in Sjögren's disease

open access: yesArthritis &Rheumatology, Accepted Article.
Objective To characterise whole‐blood transcriptomic profiles in adults with active Sjögren's disease (SjD) treated with anti‐CD20 or BlyS/BAFF inhibition, identify markers of clinical response, and define inflammatory pathways linked to non‐response. Methods Whole‐blood RNA sequencing was performed at baseline and week‐24 in participants (n=43) from a
