Brief Summary:
The purpose of the study to determine whether the level of inflammation may be decreased, the lifespan of red blood cells increased and the clearance of waste products in the blood improved through the use of the Allient System as compared to conventional hemodialysis.

Condition or disease Intervention/treatment Phase
End Stage Renal Disease Chronic Kidney Failure Device: Allient System Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Non-Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Uremic Toxin Removal, Blood Cell Kinetics, and Inflammatory Response in Patients Treated With the Allient System
Study Start Date : November 2008
Actual Primary Completion Date : February 2011
Estimated Study Completion Date : January 2014

Arm Intervention/treatment
Experimental: A
Subject will continue conventional hemodialysis therapy for one week ("no intervention" phase) and then swtich to the Allient system for two weeks ("active comparator" phase).
Device: Allient System
The Allient System uses a different type of blood pump and a lower volume of dialysate.

Primary Outcome Measures :
  1. Clearance of specific waste products from blood determined through subject blood and dialysate samples [ Time Frame: 3 weeks ]

Secondary Outcome Measures :
  1. Inflammation as determined by levels of specific inflammatory markers [ Time Frame: 3 weeks ]
  2. Red blood cell lifespan determined through a measurement of CO in the subject's breath [ Time Frame: 3 weeks ]
