Abstract
Objective: The present study determined if vitamin D defi-ciency is a potential risk factor for increased carotid in-tima-media thickness (CIMT) in patients with rheumatoid arthritis (RA).
Methods: This cross-sectional study analyzed 50 consecutive female RA patients without cardiovascular disease history at the Pusan National University Hospital between September and December of 2013. CIMT was measured us-ing a high-resolution ultrasonography. Serum 25-hydroxy vitamin D (25-OHD) levels were assessed by radioimmuno-assay, and vitamin D deficiency was defined as serum 25-OHD levels £¼20 ng/mL. Stepwise multivariable linear regression analyses were performed to evaluate the associa-tion between vitamin D deficiency and increased CIMT.
Results: The median 25-OHD level (inter-quartile range) was 14.0 (11.0¡20.7) ng/mL, and 74% of patients had vita-min D deficiency. The mean¡¾standard deviation of CIMT was 0.58¡¾0.08 mm. RA patients with vitamin D deficiency had significantly higher CIMT than those without this fea-ture (0.59¡¾0.07 vs 0.54¡¾0.05, p=0.028). In univariable line-ar regression models, vitamin D deficiency (¥â(SE)=0.047 (0.021), p=0.028), older age (¥â(SE)=0.003 (7.2-4), p£¼0.001) and higher disease activity score 28-erythrocyte sed-imentation rate (¥â(SE)=0.021 (0.010), p=0.034) and Korean version of health assessment questionnaire score (¥â(SE)=0.051 (0.015), p=0.002) were significantly asso-ciated with increased CIMT. Vitamin D deficiency re-mained statistically significant in multivariable regression models after adjusting for confounders.
Conclusion: Vitamin D deficiency was associated with in-creased CIMT in female RA patients. Our finding suggests that hypovitaminosis D can be a risk factor for athero-sclerosis in RA patients.
