Prospective study of 6 newly Dx RA pts starting MTX shows MTX causes a decline in T follicular helper (Tfh) cells and plasmablasts (@ wk 3 before clin response), selectively in responders but not nonresponders. MTX shifts cellular & gene expression towards a more physiological https://t.co/scmfAAE9XA

Where are we with Biomarkers in Rheumatoid Arthritis?

Jack Cush, MD

Biomarker interest has grown considerably in the last 2 decades, owing to advances in genetics, imaging, protein, and multiomics. Despite these advances, biomarkers as the predictive holy grail of RA therapeutics and prognostication have not yet advanced beyond rheumatoid serologies and C-
