ABSTRACT
To identify features associated with long-term persistent remission in rheumatoid arthritis (RA) patients on tapered biological disease-modifying antirheumatic drugs (bDMARD) (tap-bDMARD) therapy. We carried out a 40-month (m) extension follow-up study of 77 RA patients from a previous 12 m tap-bDMARD study. Disease activity was assessed at baseline and every 3 months. Doppler US investigation of 42 joints for the presence and grade (0-3) of B-mode synovial hypertrophy (SH) and synovial power Doppler signal (i.e., Doppler synovitis) was performed before starting the tap-bDMARD strategy by a rheumatologist blinded to clinical and laboratory data. At the 40 m mark, 44 (57.1%) patients failed the tap-bDMARD strategy, while 33 (42.9%) succeeded. Patients who presented a failed tap-bDMARD had significantly longer disease duration, a longer time from symptom onset to synthetic (s) DMARD start, longer duration of sDMARD treatment, a greater number of sDMARDs, and a higher baseline DAS28 and SDAI than patients with successful tap-bDMARD at 40 months. In logistic regression analysis, the presence of baseline Doppler synovitis, a DAS28 ≥ 2.2, and the presence of rheumatoid factor were identified as predictors of tap-bDMARD failure at 40 m. In those patients who succeed tap-bDMARD at 12 m, a smoking habit was significantly more frequently found in tap-bDMARD failures at 40 m. Our results showed that DAS28 and the presence of Doppler synovitis, RF and a smoking habit predicted long-term tap-bDMARD failure.
