Time to achieve remission determines time to be in remission

Area of Science:

• Rheumatology
• Clinical Research
• Disease Management

Background:

• Rheumatoid arthritis (RA) treatment aims for remission, but achieving sustained remission in practice remains challenging.
• Early achievement of remission is hypothesized to correlate with its long-term sustainability.

Purpose of the Study:

• To investigate the association between the time it takes to achieve remission and the sustainability of remission.
• To analyze this relationship in a cohort of early rheumatoid arthritis patients managed in a real-world clinical setting.

Main Methods:

• Utilized three-year follow-up data from 753 early RA patients (Nijmegen RA Inception Cohort, 1985-2005).
• Defined remission using Disease Activity Score (DAS)<1.6 and ACR criteria; sustained remission required at least 6 months.
• Employed Cox-regression and longitudinal binary regression for data analysis.

Main Results:

• 52% of patients (N=398) achieved remission, with a median time-to-remission of 12 months.
• Male gender, younger age, and low baseline DAS predicted faster remission.
• Sustained remission (36% of patients, N=142) was solely predicted by a shorter time-to-remission (OR 1.11).

Conclusions:

• A shorter time to remission is significantly associated with the sustainability of remission in rheumatoid arthritis.
• These findings support the clinical strategy of aiming for early remission in RA patients.
