Abstract

Background It is stated that low-dose glucocorticoids (GCs) should be considered as part of the initial treatment strategy with rheumatoid arthritis (RA), but should be tapered as rapidly as clinically feasible in overarching principles with EULAR recommendations 2013 [1].

Objectives To assess treatment outcome tapering glucocorticoids (GCs) in accordance with EULAR recommendations 2013 with Tocilizumab (TCZ) treatment for 24 months by using multi-center registry for the treatment of RA with biologics in Japan (Tsurumai Biologics Communication Registry; TBCR) [2].

Methods 276 RA patients treated with TCZ for at least 24 months in Nagoya University Hospital and 12 affiliated institutes (TBCR Study Group) were enrolled in this study. We compared three groups which are TCZ treatment without GCs at the baseline (n=95), with stopping GCs by 24 months (n=78) and with persistence of GCs for 24 months (n=103). Difference in baseline characteristics was summarized in Table.1. We assessed disease activity with DAS28-ESR, retention rate of drug continuity with Kaplan-Meier method for 24 months and the proportion of achievement with low disease activity and remission on DAS28-ESR. The last observation carried forward (LOCF) method was used in each analysis.

Results In GCs(-) group, GCs withdrawal group and GCs continuation group, the values of DAS28-ESR at the baseline were 5.39, 5.57, 5.77, respectively. Although each group significantly improved in DAS28-ESR, it is significantly different in the three groups at 24 months by one-way ANOVA (Fig. 1). The continuation rate of TCZ treatment associated with inadequate response (IR) and adverse events (AEs) was significant difference between GCs withdrawal group and GCs continuation group (Log-rank test: p=0.007; IR p=0.006; AEs) (Fig. 2). The two years continuation rate associated with IR is 88.0, 95.8, 82.6% in each group. The proportion of achievement with low disease activity and remission on DAS28-ESR is 65.5, 67.1, 45.1% in each group at 24 months (Fig.3).

Conclusions We confirmed that the good outcome of TCZ treatment by stopping GCs with effectiveness and safety.
