NCT02194114

Brief Summary

The primary purpose of this study is to assess dietary protein requirements in clinically stable maintenance hemodialysis (MHD) patients. It is hypothesized that the average dietary protein intake (DPI) that will maintain nitrogen balance is 1.00 g protein/kg/day, but that a safe intake that maintains balance in almost all MHD patients is about 1.25g protein/kg/day.
