Abstract

Objectives

To identify baseline predictors of remission and low disease activity (LDA) in early rheumatoid arthritis (RA) from the GLADAR (Grupo Latino Americano De estudio de la Artritis Reumatoide) cohort.

Methods

Patients with 1- and 2-year follow-up visits were included. Remission and LDA were defined by DAS28-ESR (< 2.6 and ≤ 3.2, respectively). Baseline predictors examined were gender, ethnicity, age at diagnosis, socioeconomic status, symptoms’ duration, DMARDs, RF, thrombocytosis, anemia, morning stiffness, DAS28-ESR (and its components), HAQ-DI, DMARDs and corticosteroid use, and Sharp-VDH score. Multivariable binary logistic regression models (excluding DAS28-ESR components to avoid over adjustment) were derived using a backward selection method (α-level set at 0.05).

Results

Four hundred ninety-eight patients were included. Remission and LDA/remission were met by 19.3% and 32.5% at the 1-year visit, respectively. For the 280 patients followed for 2 years, these outcomes were met by 24.3% and 38.9%, respectively. Predictors of remission at 1 year were a lower DAS28-ESR (OR 1.17; CI 1.07–1.27; p = 0.001) and HAQ-DI (OR 1.48; CI 1.04–2.10; p = 0.028). At 2 years, only DAS28-ESR (OR 1.40; CI 1.17–1.6; p < 0.001) was a predictor. Predictors of LDA/remission at 1 year were DAS28-ESR (OR 1.42; CI 1.26–1.61; p < 0.001), non-use of corticosteroid (OR 1.74; CI 1.11–2.44; p = 0.008), and male gender (OR 1.77; CI 1.2–2.63; p = 0.036). A lower baseline DAS28-ESR (OR 1.45; CI 1.23–1.70; p < 0.001) was the only predictor of LDA/remission at 2 years.

Conclusions

A lower disease activity consistently predicted remission and LDA/remission at 1 and 2 years of follow-up in early RA patients from the GLADAR cohort.

Key Points

In patients with early RA, a lower disease activity at first visit is a strong clinical predictor of achieving remission and LDA subsequently.

Other clinical predictors of remission and LDA to keep in mind in these patients are male gender, non-use of corticosteroids and low disability at baseline.

Not using corticosteroids at first visit is associated with a lower disease activity and predicts LDA/remission at 1 year in these patients.
