Vitamin D, Insulin Resistance and Inflammation in ESRD
Phase 2
Completed
- Conditions
- End Stage Renal Disease
- Registration Number
- NCT00656032
- Lead Sponsor
- Vanderbilt University
- Brief Summary
The broad goal of this study is to understand the mechanisms by which Vitamin D receptor activation leads to changes in insulin signaling in advanced uremia. We hypothesize that 1,25-Dihydroxyvitamin D3 deficiency due to advanced chronic kidney disease leads to insulin resistance and that administration of a vitamin D3 analog will restore insulin sensitivity in End Stage Renal Disease patients.
