  Purpose

The proposed controlled, randomized study aims to compare pre-dilution hemodiafiltration (HDF) and low flux hemodialysis (HD) regarding acute changes in the brain.

The study consist of two examination days placed one week apart. 12 HD patients will be recruited to the study. The patients will be randomly placed in two groups: Pre-dilution hemodiafiltration during the first examination and low flux hemodialysis during the second day or vice versa.

Brain Magnetic Resonance Imaging (MRI) will be obtained before and after both treatments. The MRI-data will later be processed to estimate brain volume changes during the two types of treatment.

End Stage Renal Disease Procedure: HDF during the first examination Procedure: HD during the first examination

Further study details as provided by University of Aarhus:

Primary Outcome Measures:
  • Percent Brain Volume Change (PBVC) [ Time Frame: Brain volume before and after one hemodialysis session (4,5 hours) and one session of hemodiafiltration (4,5 hours). Dialysis sessions are performed one week apart. ]

    Brain volume before and after one hemodialysis session (4,5 hours) and one session of hemodiafiltration (4,5 hours). Dialysis sessions are performed one week apart. Randomization determines the order of treatment (hemodialysis vs hemodiafiltration).

    MRI-data will later be processed to estimate the PBVC.

Arms Assigned Interventions
Active Comparator: First treatment HDF
The patient will receive treatment with pre-dilution hemodiafiltration during the first examination day. During the second examination day the patient will receive treatment with low flux hemodialysis.
Procedure: HDF during the first examination

The patient will receive treatment with pre-dilution hemodiafiltration during the first examination.

During the second examination the patient will receive treatment with low flux hemodialysis.

MRI of the brain will be performed before and after the treatment. The MRI-data will later be processed to determine the degree of brain volume change due to the treatment.

Active Comparator: First treatment HD
The patient will receive treatment with low flux hemodialysis during the first examination day. During the second examination day the patient will receive treatment with pre-dilution hemodiafiltration.
Procedure: HD during the first examination

The patient will receive treatment with low flux hemodialysis during the first examination.

During the second examination the patient will receive treatment with pre-dilution hemodiafiltration.

MRI of the brain will be performed before and after the treatment. The MRI-data will later be processed to determine the degree of brain volume change due to the treatment.
