Valor L, et al. - Researchers evaluated the features related to long-term persistent remission in rheumatoid arthritis (RA) patients on tapered biological disease-modifying antirheumatic drugs (bDMARD) (tap-bDMARD) therapy. Significantly more frequently a smoking habit was found in tap-bDMARD failures at 40 m in those patients who succeed tap-bDMARD at 12 m. Long-term tap-bDMARD failure was predicted by DAS28 and the presence of Doppler synovitis, RF and a smoking habit.
