Methods Among early arthritis patients included in the ESPOIR cohort, patients with early RA were evaluated. 25OH vitamin D2D3 level was measured at baseline. Baseline associations between vitD level and DAS28-ESR, Health Assessment Questionnaire Disability Index (HAQ-DI) and van der Heijde-modified total Sharp score (mTSS) were assessed. Bivariate analysis was used to assess the association between vitD level and radiographic progression (mTSS increased by ≥1 point) or disability (HAQ-DI ≥0.5) over 12 months. Forward stepwise multiple logistic regression was used to evaluate the independent association of baseline variables and outcomes. Results Among 813 patients with early arthritis, data for 645 RA patients were analyzed. VitD level was <10 ng/ml (deficiency, group 1), 10-30 ng/ml (low level, group 2) and ≥30 ng/ml (normal, group 3) for 114 (17.7%), 415 (64.6%), and 114 (17.7%) patients, respectively. At baseline, DAS28-ESR and HAQ-DI were higher with vitD deficiency as compared with groups 2 and 3 combined (p=0.007 and p=0.001, respectively) as was mean mTSS but not significantly (p=0.076). On multivariate analysis, baseline vitD deficiency was associated with HAQ-DI at 6 months (OR=1.70) and mTSS at 12 months (OR=1.76). Conclusion VitD deficiency was associated with more active and severe disease at baseline and may predict disability and radiographic progression over 1 year in early RA patients.
