  Purpose

Patients will be treated with hemodiafiltration (HDF) in postdilution mode, as a control therapy, during 9 weeks. During week 5 the 1st intervention treatment, predilution hemofiltration (HF) or predilution HDF, will be performed as a midweek session. After 4 additional weeks of control therapy the other intervention treatment will be performed. Samples will be taken during week 4, 5 and 9: from inlet blood flow (0, 30, 60, 120 and 240 min), from outlet blood flow and dialysate outflow (30, 60, 120 and 240 min).

Primary Outcome Measures:
  • To evaluate what is more effective for convective removal of protein-bound solutes - predilution or postdilution of blood? [ Time Frame: Samples taken at week 4, 5 and 9. Bloodsamples taken at 0, 30, 60, 120 and 240 min. Dialysate taken at 30, 60, 120 and 240 min. ] [ Designated as safety issue: No ]
  • To check which respective roles diffusion and convection play in the removal of protein-bound uremic toxins? [ Time Frame: Samples taken at week 4, 5 and 9. Bloodsamples taken at 0, 30, 60, 120 and 240 min. Dialysate taken at 30, 60, 120 and 240 min. ] [ Designated as safety issue: No ]
