Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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
