Abstract
Objective. To evaluate the association between rheumatoid arthritis (RA)-related autoantibodies and plasma 25,OH vitamin D in subjects at risk for RA. Methods. In 1210 subjects without RA, 76 were positive for anti-cyclic citrullinated peptide antibodies or for at least 2 rheumatoid factors (RF; by nephelometry: RF-IgM, RF-IgG, RF-IgA). 25,OH vitamin D was measured in these cases and 154 autoantibody-negative controls from this cohort. Results. 25,OH vitamin D levels did not differ between cases and controls (adjusted OR 1.23, 95% CI 0.93-1.63). Conclusion. Vitamin D concentrations are not associated with RA-related autoimmunity in unaffected subjects at increased risk for RA. The Journal of Rheumatology
