Effect of Vitamin D Supplementation on Erythropoietin Dosage in Hemodialysis Patients Who Have Vitamin D Deficiency
An observational study of Vitamin D Deficiency and Anemia, run by Kaiser Permanente at 1 site in United States.
Trial summary
While vitamin D supplementation is safe and effective in repleting vitamin D levels in dialysis patients, the impact on anemia is unknown. The majority of hemodialysis patients require erythropoietin supplementation to maintain their serum hemoglobin between 11 and 12 gm/dL, a drug that is both costly and associated… Read more about this study

About this study
While vitamin D supplementation is safe and effective in repleting vitamin D levels in dialysis patients, the impact on anemia is unknown. The majority of hemodialysis patients require erythropoietin supplementation to maintain their serum hemoglobin between 11 and 12 gm/dL, a drug that is both costly and associated with significant side effects. If repletion of vitamin D significantly decreases erythropoietin requirements in hemodialysis patients, it would result in a substantial reduction in patient care costs. Our aim is to study the impact of ergocalciferol supplementation in hemodialysis patients with 25-hydroxyvitamin D deficiency. The investigators anticipate approximately 30% reduction in erythropoietin dose requirement in our hemodialysis population.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
While vitamin D supplementation is safe and effective in repleting vitamin D levels in dialysis patients, the impact on anemia is unknown. The majority of hemodialysis patients require erythropoietin supplementation to maintain their serum hemoglobin between 11 and 12 gm/dL, a drug that is both costly and associated with significant side effects. If repletion of vitamin D significantly decreases erythropoietin requirements in hemodialysis patients, it would result in a substantial reduction in patient care costs. Our aim is to study the impact of ergocalciferol supplementation in hemodialysis patients with 25-hydroxyvitamin D deficiency. The investigators anticipate approximately 30% reduction in erythropoietin dose requirement in our hemodialysis population.

Questions about this trial
What is this clinical trial studying?
An observational study of Vitamin D Deficiency and Anemia, run by Kaiser Permanente at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 11 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
erythropoietin dosage (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00915317, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2015.
