  Objectives: To determine the necessity of methotrexate (MTX) in patients with rheumatoid arthritis (RA) achieving clinical remission treated by tocilizumab (TCZ) and MTX (TCZ+MTX). Methods: A 3 year, multicenter, observational cohort study was performed. RA patients were treated by TCZ with or without MTX depending on the attending doctor’s decision. Of the patients treated with TCZ+MTX, the patients who discontinued MTX after achieving clinical remission (discontinued group: DISC) were compared with those who maintained the same dose of MTX after achieving clinical remission (maintained group: MAIN). Results: The DISC and MAIN consisted of 33 patients and 37 patients, respectively. The mean DAS28-ESR was significantly lower in the DISC than in the MAIN at 3 months, 6 months and 9 months (3 months: 1.8 &plusm.. View More»
