The purpose of this study is to investigate the effect of vitamin D repletion on disease activity and disability in patients with rheumatoid arthritis.

The investigators hypothesize that rheumatoid arthritis (RA) patients with vitamin D deficiency have greater disease activity and disability, compared to RA patients with normal vitamin D levels. The investigators also hypothesize that vitamin D treatment in these deficient patients will result in a decrease in RA disease activity and disability.

Arms Assigned Interventions
Placebo Comparator: placebo group

RA Patients with vitamin D deficiency will be randomized to placebo and active intervention arms.

Patients in the placebo arm will receive I placebo pill per week for 16 weeks. After completing this arm, they will cross-over to the active treatment arm.

Drug: Placebo sugar pill
Intervention includes 1 sugar pill once a week for 16 weeks dispensed as a capsule.
Other Name: Placebo
Active Comparator: Ergocalciferol
Patients with vitamin D deficiency will be randomized to either active or placebo group. In the active group, patients will receive ergocalciferol 50,000 IU per week for 16 weeks.
Drug: Ergocalciferol
Ergocalciferol 50,000 IU per week for 16 weeks
