Abstract

Objective

The aim of our study was to assess the disease activity in patients with rheumatoid arthritis (RA) using Rheumatoid Arthritis Disease Activity Index-5 (RADAI-5) questionnaire and to find its correlation with Disease Activity Score-28 (DAS28), quality of life, pain, and functional status.

Patients and methods

A total of 40 patients with RA were included. Quality of life was evaluated by Quality of Life–Rheumatoid Arthritis scale. The severity of pain was measured by 100-mm visual analog scale-pain. Health Assessment Questionnaire Disability Index was used to evaluate functional status. Disease activity was measured by using the DAS28 and RADAI-5.

Results

Mean RADAI-5 score was 4.2±1.7 (moderate disease activity). A total of seven (17.5%) patients were in remission, four (10%) patients had mild disease activity, 19 (47.5%) patients had moderate disease activity, and 10 (25%) patients had high disease activity. RADAI-5 was significantly correlated with DAS28, quality of life scale, pain scale, and functional status (r=0.9, P<0.001; r=0.9, P<0.001; r=0.4, P=0.02; and r=0.6, P<0.001, respectively). Moreover, RADAI-5 was found to be significantly correlated with morning stiffness duration, Ritchie articular index, tender 28-joint count, swollen 28-joint count, erythrocyte sedimentation rate, anticyclic citrullinated peptide, and rheumatoid factor positivity (r=0.3, P=0.03; r=0.8, P<0.001; r=0.9, P<0.001; r=0.7, P<0.001; r=0.6, P<0.001; r=0.6, P<0.001; and r=0.4, P=0.008, respectively).

Conclusion

RADAI-5 is a simple and low-cost self-report questionnaire that reflects patients’ perception of signs and symptoms. The correlations of RADAI-5 with DAS28, quality of life, pain, and functional status reflect its value in the assessment of disease activity in patients with RA.
