Uremic Toxin Removal and Hemodynamics in Long-hour Hemodialysis and Hemodiafiltration

Uremic Toxin Removal and Hemodynamics in Long-hour Hemodialysis and Hemodiafiltration; a Randomized Cross-over Study

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 20 (actual)
• Sponsor: Maastricht University Medical Center · Academic / Other
• Sex: All
• Age: 18 Years – 80 Years
• Healthy volunteers: Not accepted

Summary

Rationale: The mortality of end-stage renal disease (ESRD) patients on dialysis remains high. This may at least be partly due to the insufficient removal of (especially protein-bound) uremic toxins which have been associated with cardiovascular morbidity and mortality. It is unknown whether the combination of long-hour haemodialysis (HD) with convection increases the removal of these toxins. Long-hour HD and long-hour haemodiafiltration (HDF) may also improve haemodynamic stability which is an important factor in treatment quality. The investigators aim to study the removal of uremic toxins in long-hour HD and HDF and to compare the haemodynamics between 4-hour and 8-hour HD and HDF. Objectives: The primary aim is to study the removal of (especially protein-bound) uremic toxins in 4-hour and 8-hour HD and HDF. A secondary aim is to compare the haemodynamic response between 4-hour and 8-hour HD and HDF.

Conditions

• Uremic Toxins
• Haemodynamic Stability

Interventions

Type	Name	Description
OTHER	4-hour HD, 4-hour HDF, 8-hour HD and 8-hour HDF	Prevalent conventional HD (CHD) patients (dialysing 3 days a week during 4 hours per dialysis session) will undergo, in random order, a mid-week 4-hour HD session, a mid-week 4-hour HDF session, a mid-week 8-hour HD session, and a mid-week 8-hour HDF session with a 2-week interval between every session to assess the influence of treatment duration and of convection on the removal of uremic toxins and on the haemodynamic responses and autonomic nervous regulation. In between the study dialysis sessions these patients will receive routine CHD treatments.
