The objective of this study is to evaluate the effect of high fiber multigrain supplementation on the level of clinical disease severity measures, blood inflammatory molecules, and nutritional status changes in RA patients.
Rheumatoid Arthritis (RA) is a chronic inflammatory, autoimmune rheumatic disease, resulting in progressive joint inflammation and destruction. At present, there is no known cure for this disease. As a consequence of the potential side effects, many RA patients turn to other alternative remedies such as specialised diets and/or dietary supplements in a bid to relieve their symptoms. Therefore, the current study aims to examine the effectiveness of high fiber multigrain supplementation on the level of clinical disease severity measures, blood inflammatory molecules, together with the nutritional status changes in RA patients, as compare with conventional drug treatments.

| Disease Activity Score-28 (DAS-28) | The DAS-28 is a system developed and validated by the EULAR (European League Against Rheumatism) to measure the progress and improvement of Rheumatoid Arthritis. DAS-28 values range from 2.0 to 10.0, while higher values mean a higher disease activity. The complex mathematical calculation is calculated by incorporating the value of erythrocyte sedimentation rate (ESR) and Visual Analog Scale (VAS). ESR (mm/hr) determines the severity of inflammatory response and monitor the effect of treatment. VAS is an indicator for pain intensity and patient global health, and the following cut points have been recommended: no pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm), and severe pain (75- 100 mm). DAS-28 = 0.56 * sqrt(tender28) + 0.28 * sqrt(swollen28) + 0.70 * ln(ESR) + 0.014 * GH The scale categorises RA manifestations as mild (DAS-28: <3.2), moderate (DAS-28: 3.2-5.1) or severe (DAS-28: >5.1) | Baseline and 12 weeks |
| Health Assessment Questionnaire-Disability Index (HAQ-DI) | The HAQ-DI is used to measure physical functionality. The HAQ-DI is usually analyzed by calculating scores. The single scales range from 0 (no difficulty) to 3 (unable to do). The total score ranges from 0-24, and higher score indicates severe disability. | Baseline and 12 weeks |
