Remission in rheumatoid arthritis: is it all the same?

Area of Science:

• Rheumatology
• Immunology
• Medical Imaging

Background:

• Remission is the primary treatment objective in rheumatoid arthritis (RA), aiming for optimal patient outcomes.
• Current clinical remission criteria, based on composite disease activity scores, are standard in practice and trials.
• Biologic therapies and treat-to-target strategies have enhanced clinical remission rates in RA.

Purpose of the Study:

• To review the historical evolution of remission criteria in rheumatoid arthritis.
• To evaluate emerging concepts and future directions for defining RA remission.
• To address the discrepancy between clinical remission and persistent structural/functional damage.

Main Methods:

• Literature review of remission criteria evolution in rheumatoid arthritis.
• Evaluation of advanced assessment methods beyond clinical scores.
• Exploration of novel biomarkers and imaging modalities for remission assessment.

Main Results:

• Despite improved clinical remission rates, many RA patients experience ongoing structural and functional deterioration.
• Clinical remission criteria's validity is questioned due to persistent disease activity.
• Imaging modalities like ultrasound and immuno-pathological assessments show promise for more accurate remission evaluation.

Conclusions:

• Current clinical remission criteria for rheumatoid arthritis may be insufficient.
• Advanced imaging and immuno-pathological assessments offer superior evaluation of RA remission.
• Further research is essential to develop precise biomarkers for defining true rheumatoid arthritis remission.
