About this study

Official title: Is the Lower Incidence of Intradialytic Hypotension During Hemocontrol Dialysis in Comparison With Standard Hemodialysis Attributable to Enhanced to Higher Plasma Vasopressin Levels or to Enhanced Sympathetic Activity and/or to Less Nitric Oxide Production

Intradialytic hypotension (IDH) is a frequent and serious complication that may occur during hemodialysis treatment. The investigators and others have shown that the Hemocontrol biofeedback system is associated with improved hemodynamic stability. Hemocontrol is a technique that guides the patients' blood volume along a pre-set trajectory by continuously adjusting the ultrafiltration rate and dialysate conductivity. In a recent pilotstudy, the investigators found significantly higher plasma vasopressin levels during the first hour of dialysis with Hemocontrol in comparison with standard hemodialysis. Increased vasopressin levels may contribute to intradialytic hemodynamic stability during hemodialysis by enhanced vasoconstriction. These results, however, did not prove directly that the improved hemodynamic stability with Hemocontrol is indeed caused by higher initial plasma vasopressin levels. Alternative explanations might be that 1) the higher initial plasma sodium levels with Hemocontrol dialysis enhance activity of the sympathetic nervous system directly, causing vasoconstriction and thereby improved hemodynamic stability and/or 2) that the higher initial plasma levels of sodium in Hemocontrol inhibit the release of nitric oxide by the vascular endothelium. Another goal of this study is to investigate whether vasopressin is removed with hemodialysis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Hemocontrol hemodialysisDevice

    Each participating patient underwent one standard hemodialysis and one hemodialysis with Hemocontrol in random order, both 4 hours in total duration. The Hemocontrol system guides the patients' blood volume along a predefined ideal relative blood volume trajectory, by continuously adjusting ultrafiltration volume and dialysate sodium concentration.

  • Standard hemodialysisDevice

    Each participating patient underwent one standard hemodialysis and one hemodialysis with Hemocontrol in random order, both 4 hours in total duration. During standard hemodialysis, a constant ultrafiltration rate and dialysate conductivity was used.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in plasma vasopressin levels

    Plasma levels of the antidiuretic hormone, i.e. vasopressin

    Measured: Before, after 30, 60, 120 and 180 minutes and after dialysis blood is withdrawn from the dialysis line to determine plasma levels of vasopressin.

Secondary outcomes (4)
  1. Change in systolic and diastolic blood pressure in mmHg

    Measured: Before, after 30, 60, 120 and 180 minutes and after dialysis

  2. Change in heart rate in beats per minute

    Measured: Before, after 30, 60, 120 and 180 minutes and after dialysis

  3. Change in relative blood volume in %

    Measured: Before, after 30, 60, 120 and 180 minutes and after dialysis

  4. Change in plasma sodium levels in mmol/L

    Measured: Before, after 30, 60, 120 and 180 minutes and after dialysis

Questions about this trial

What is this clinical trial studying?

A study testing Standard hemodialysis in people with Patients With End Stage Renal Disease on Hemodialysis, run by University Medical Center Groningen at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in plasma vasopressin levels (time frame: Before, after 30, 60, 120 and 180 minutes and after dialysis blood is withdrawn from the dialysis line to determine plasma levels of vasopressin.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03578510, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 May 2023.
