Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Alanine-infusion
Alanine infusion taking place over a 3 hour period while monitorering metabolic changes in blood samples before and after dialysis
|
During 3 hours, patient will receive alanine-infusion, while amino-acid and urea will be monitored by blood samples.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Urea synthesis rate during alanine infusion
Time Frame: 4 hours. 1 hour of blood sample measuring of baseline urea-synthesis rate and 3 hours of urea-synthesis rate during alanine-infusion
|
Change in the synthesis of urea during a 3 hour period of alanine-infusion in pre and post hemodialysis patients.
We will use a validated method named functional hepatic nitrogen clearance (FHNC) to evaluate the synthesis of urea.
FHNC is calculated using the linear relation between urea nitrogen synthesis rate and blood-amino acid which is measured every hour.
An estimated group of 10 dialysis patients will be included and compared to a clinical healthy group.
The healthy group has also received alanine infusion and blood samples of urea and amino-acids has likewise been measured for every hour of infusion.

4 hours. 1 hour of blood sample measuring of baseline urea-synthesis rate and 3 hours of urea-synthesis rate during alanine-infusion
