Treatment of Vitamin D Deficiency in Patients With Rheumatoid Arthritis

January 27, 2017 updated by: Johns Hopkins University

Vitamin Therapy in Rheumatoid Arthritis

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 and Interventions

Participant Group / Arm
Intervention / Treatment
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.

Intervention includes 1 sugar pill once a week for 16 weeks dispensed as a capsule.
Other Names:
  • Placebo
Ergocalciferol 50,000 IU per week for 16 weeks
Other Names:
  • 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.
Ergocalciferol 50,000 IU per week for 16 weeks

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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).

Baseline and 16 weeks (end of Randomized Controlled Trial (RCT))

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Baseline and 16 weeks (end of RCT)
