AB1312 Effects of vitamin d on disease activity, functional disability and serum interleukin-6 in rheumatoid arthritis
2018
Background Vitamin D may have a potential role in rheumatoid arthritis (RA) pathogenesis by inhibiting the expression of pro-inflammatory cytokines including interleukin-6 (IL-6) 1–2 . Objectives The aim of this study is to determine the clinical factors of vitamin D deficiency in a multi-ethnic Malaysian RA patients and its association with disease activity, functional disability and serum IL-6 level. Methods One-hundred RA patients and 50 healthy controls, age- and sex-matched were recruited. DAS28 and HAQ score were assessed. Baseline serum vitamin D and IL-6 were measured in all subjects. RA patients who were vitamin D deficient were given loading dose of vitamin D3 and repeated assessments were done. Results Vitamin D deficiency ( Conclusions Vitamin D deficiency is prevalent in Malaysian RA patients. This study suggests that vitamin D does not have a role in disease activity or serum IL-6 but it may have a role in functional disability in RA patients.
