Treatment of Vitamin D Deficiency in Patients With Rheumatoid Arthritis - Full Text View

Purpose

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.

Primary Outcome Measures:

Disease Activity Score (DAS) 28 [ Time Frame: Baseline and 16 weeks (end of Randomized Controlled Trial (RCT)) ]
We measured disease activity as measured by DAS 28 at baseline and at the completion of Randomized Controlled trial, both in the placebo and the active treatment group.

We used DAS-28 scores to indicate disease activity. The DAS -28 scale has a minimum of 0 and a maximum of 10, with higher numbers indicating higher disease activity.

We used the following cut-offs: Remission (< 2.6), low disease activity (< 3.2), moderate disease activity (< 5.1) and high disease activity (> 5.1).

Secondary Outcome Measures:

Physical Function as Measured by Arthritis Impact Measurement Scales - Short Form (AIMS2 - SF) [ Time Frame: Baseline and 16 weeks (end of RCT) ]
In each dimension and component of AIMS2-SF, item scores are from 0 to 10 with 10 being worst health.

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 Drug: Ergocalciferol Ergocalciferol 50,000 IU per week for 16 weeks Other Name: Vitamin D
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 Other Name: Vitamin D
