In patients with rheumatoid arthritis (RA), attaining remission is highly specific for attaining low disability and normal health-related quality of life (HRQoL), a new study found. Researchers studied 571 patients in 2 clinical trials, and 1,693 patients in a 10-year routine care cohort. They assessed the frequency and sustainability of remission and low-disease activity (LDA)/remission, variability in DAS28-ESR after remission, sensitivity/specificity of remission, and LDA/remission at identifying patients with low disability levels and normal HRQoL. Among the findings:
- Point remission and remission/LDA were common but were rarely sustained.
- Following attaining remission, DAS28-ESR levels varied substantially.
- Most patients attaining point remission were in remission at study end-points.
- Attaining a DAS28-ESR ≤3.2 had a better balance of specificity and sensitivity for attaining positive outcomes.
