This study has been terminated.
(Strong enrollment efforts resulted in few eligible subjects and high screen failures due to CKD patients with higher vitamin D levels than anticipated.)

Hypothesis: The supplementation of Ergocalciferol (Vitamin D2) to those with Vitamin D deficiency in the Chronic Kidney Disease population requiring recombinant human erythropoietin for the treatment of anemia related to kidney disease will reduce the dose of erythropoietin required to maintain a nonanemic state.

Condition Intervention
Chronic Kidney Disease Stages 3-5 Drug: Ergocalciferol supplementation

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Effects of Ergocalciferol on Erythropoetin Stimulating Agent Dose

Primary Outcome Measures:
  • Evaluate if Ergocalciferol Supplementation to Achieve 25-hydroxy Vitamin D Levels > 40ng/ml Will Decrease Erythropoietin Requirements [ Time Frame: 24 Weeks ]

Secondary Outcome Measures:
  • Change in Inflammatory Markers [ Time Frame: 24 Weeks ]
  • Change in Calcium, Phosphorous,Calcium x Phosphorous Product, and Parathyroid Hormone Levels [ Time Frame: 24 Weeks ]
  • Change in Iron Supplementation [ Time Frame: 24 Weeks ]
  • Change in Erythropoietin Adjusted for Change in Inflammatory Markers, Vitamin D Levels and Clinical and Demographic Confounders [ Time Frame: 24 Weeks ]

Enrollment: 6
Study Start Date: August 2010
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ergocalciferol supplementation Drug: Ergocalciferol supplementation
Vitamin D in the form of ergocalciferol will be the drug utilized in the study. This medication is a Vitamin D analog and is normally used in the current study population to help augment those who are deficient in Vitamin D.
