Abstract

Objectives With early and intensive treatment many patients with early RA attain remission. Aims were to investigate (1) the frequency and time to sustained remission and subsequent tapering in patients initially treated with conventional synthetic disease modifying anti-rheumatic drug ((cs)DMARD) strategies and (2) the frequency and time to flare and regained remission in patients tapering csDMARDs and biological (b)DMARDs during 2 years of follow-up.

Methods Two-year follow-up data from the treatment in the Rotterdam Early Arthritis Cohort (tREACH) cohort were used. Patients were randomised to initial treatment with triple DMARD therapy (iTDT) with glucocorticoid (GC) bridging or methotrexate monotherapy (iMM) with GC bridging. Patients were evaluated every 3 months. In case Disease Activity Score (DAS) was >2.4 treatment was switched to a TNF-blocker. In case DAS<1.6 at 2 consecutive time points, tapering was initiated according to protocol. Outcomes were rates of sustained remission (DAS<1.6 at 2 consecutive time points), flare (medication increase after tapering) and remission after flare (DAS<1.6). Data were analysed using Kaplan-Meier analyses.

Results During 2 years of follow-up, sustained remission was achieved at least once by 159 (57%) of patients, of whom 118 and 23 patients initiated tapering of csDMARDs and bDMARDs, respectively. Thirty-four patients achieved drug-free remission. Flare rates were 41% and 37% and within 1 year, respectively. After flare, 65% of patients tapering csDMARDs re-achieved remission within 6 months after treatment intensification.

Conclusions Regardless of initial treatment strategy, 57% of patients achieved sustained remission during 2 years of follow-up. Flare rates were 41% and 37% within 12 months in patients tapering csDMARDs and bDMARDs, respectively.
