Abstract

Background: Remission nowadays is the guiding target of management of rheumatoid arthritis (RA). However, no gold standard definition of remission exists and the inclusion of patient global assessment (PGA) in remission definitions is debated (1). Objectives: To determine the impact of excluding PGA from the ACR/EULAR Boolean remission criteria, upon prediction of radiographic outcome of RA. Methods: Meta-analyses using individual patient data from randomized controlled trials (identified through PubMed and Clinicaltrials.gov until 2017) testing the efficacy of biological agents on radiographic outcomes at ≥2 years. Remission was defined using the ACR/EULAR remission criteria with 4 variables (Figure 1): (i) tender and swollen 28-joint counts (TJC28/SJC28), C-reactive protein (CRP, mg/dl), and PGA (0-10=worst) all ≤1 (4V-remission), (ii) the same, except PGA>1 (4V-near-remission) (iii) 3V-remission (similar to 4V, but without PGA, i.e. equal to the combination of i and ii), and (iv) non-remission (TJC28 and/or SJC28 and/or CRP >1). Meta-analyses were performed using the DerSimonian-Laird random-effects method. Good radiographic outcome (GRO) was defined as an increase of ≤0.5 modified Total Sharp score (mTSS) units. The relationship between the most stringent remission class achieved at 6 or 12 months and GRO during the second year was analysed. The pooled probabilities of GRO for the different definitions of remission were estimated and compared. Results: Individual patient data (n=5,792) from eleven trials were analysed. 4V-remission was achieved by 23% of patients (95%CI: 18-28%) and 4V-near-remission by 19% (95%CI: 15-22%) and thus, 3v-remission by 42% (95%CI: 36-48%). The probability of GRO in the 4V-near-remission group was similar to that of 4V-remission (78 vs 81%, ns) and significantly higher than that for non-remission (72%; difference 6%; 95%CI: 2-10%) (Table 1). These results were confirmed by meta-analyses of odds ratios of obtaining GRO of these groups (Graph 1). 3V-remission showed a higher predictive value for GRO (51%, 95%CI: 47-55%) than 4V-remission (41%, 95%CI: 35-46%) (Figure 2). Conclusion: 4V-near-remission and the original 4V-remission are similarly predictive of GRO, therefore combining these in the 3V-remission definition potentially reduces the risk of overtreatment compared to the 4V definition. This supports the use of 3V-remission as the target for immunosuppressive therapy. The patient's perspective, which must remain central, requires a separate treatment aim: a dual-target approach.
