Study Summary

The purpose of this study is to describe the circadian rhythm of serum and salivary phosphorus in patients with chronic kidney disease and determine its' modification in response to changes in dietary phosphate load.

Primary Outcome

After 1 week of a controlled phosphorus diet patients will be hospitalized for 24 hours and serum phosphorus will be obtained every 4 hours. After a 4 day washout, each subject will cross over to a low phosphorus diet (for 1 week) followed by a 4 day washout and cross over to a high phosphorus diet for 1 week. At the end of each weekly diet a 24 hour hospitalization will occur with samples collected every 4 hours.
