Frequency of Remission, Low Disability in RA Studied

Semin Arthritis Rheum; ePub 2018 Dec 28; Scott, et al

Attaining remission in rheumatoid arthritis (RA) is highly specific for attaining low disability and normal health-related quality of life (HRQOL), although many patients with more active disease also have good function and HRQOL, a recent study found. Furthermore, attaining a Disease Activity Score 28-erythrocyte sedimentation rate (DAS28-ESR) ≤3.2 has a better balance of specificity and sensitivity for attaining these outcomes, with the benefit of being more readily achievable. Researchers studied 571 patients in 2 clinical trials, and 1,693 patients in a 10-year routine care cohort. They found:

  • Point remission and remission/low disease activity (LDA) were common (achieved by 35-58% and 49-74% of patients, respectively), but were rarely sustained (sustained remission and remission/LDA achieved by 5-9% and 9-16% of patients, respectively).
  • Following attaining remission, DAS28-ESR levels varied substantially.
  • Despite this, of those patients attaining point remission, the majority (53-61%) were in remission at study end-points.
  • While remission was highly specific at identifying patients with low disability (85-91%), it lacked sensitivity (51-57%); similar findings were seen for normal HRQOL (specificity 78-86%; sensitivity 52-59%).
