Vitamin D
One hundred RA patients and 50 healthy controls, sex- and age-matched, were recruited. Disease Activity Score of 28 joints and Health Assessment Questionnaire scores were assessed. Baseline serum 25(OH)D
Vitamin D deficiency (<50 nmol/L) was found in 63% of RA patients and 76% of healthy controls. Chinese RA patients and healthy controls had significantly more sufficient 25(OH)D
Vitamin D deficiency is prevalent in Malaysian RA patients. This study suggests that vitamin D is not associated with disease activity or serum IL-6 levels but it may have a role in functional disability in RA patients.
