Trial Summary

What is the purpose of this trial?

Kidney failure has been recognized as one of the most costly chronic conditions among United States Veterans. Approximately 13,000 Veterans develop kidney failure each year, and most require hemodialysis initiation. Hemodialysis patients suffer significantly increased risk of death and hospitalizations, and excessive body fluid is a major cause of this. While empiric aggressive fluid removal during dialysis is one approach to limit fluid overload, this can cause dangerous decreases in blood pressure during dialysis that independently contribute to the high death rate. In this study, I aim to test a new strategy that prescribes fluid removal based on a patient's recent blood pressure patterns during dialysis. This clinical trial will compare my strategy to standard care and assess the outcomes of overall blood pressure change between dialysis treatments in addition to the number of times the blood pressure becomes dangerously low during dialysis. Another aim is to determine how differences in the structure and function of the heart influence blood pressure during dialysis.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it excludes those who routinely use certain blood pressure medications during dialysis. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the treatment IBPS-Guided Ultrafiltration for Kidney Failure?

Research shows that slow continuous ultrafiltration can be effective for patients with acute kidney failure, especially those who are unstable, as it helps manage fluid levels and blood pressure better than traditional methods. Additionally, ultrafiltration is used in heart failure patients to manage fluid overload, improving symptoms and quality of life.12345

Is IBPS-Guided Ultrafiltration generally safe for humans?

Research on ultrafiltration, a process used in kidney treatments, shows that it can be safe when done slowly and carefully, as it helps maintain stable blood pressure and doesn't require blood thinners. However, doing it too quickly can cause low blood pressure, which is a common side effect.26789

How is IBPS-Guided Ultrafiltration treatment different from other treatments for kidney failure?

IBPS-Guided Ultrafiltration is unique because it uses a noninvasive method to monitor blood volume, which can help manage fluid overload more precisely. This approach may offer greater blood pressure stability and ease of operation compared to traditional hemodialysis, especially in patients who are hemodynamically unstable (have unstable blood pressure).27101112

Eligibility Criteria

This trial is for Veterans with kidney failure who are on hemodialysis and have high blood pressure before or after treatments. They must not be pregnant, have a pacemaker, metallic implants, or severe low blood pressure issues. Also excluded are those new to dialysis, using certain blood pressure medications during dialysis, or non-adherent to antihypertensive meds.

Inclusion Criteria

I am on hemodialysis.
My average blood pressure before or after dialysis is above the normal range.

Exclusion Criteria

Your blood pressure before or after dialysis is consistently higher than 180 mmHg.
I have not consistently taken my blood pressure medication as prescribed.
I have been on hemodialysis for less than 2 months.

Treatment Details

Interventions

  • IBPS-Guided Ultrafiltration (Behavioural Intervention)
Trial OverviewThe study tests a new method of removing fluid during dialysis based on patients' recent blood pressure trends compared to standard care. It aims to see if this can manage overall blood pressure better and reduce dangerous drops in blood pressure that occur during the treatment process.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: IBPS (Intradialytic Blood Pressure Slope) ArmExperimental Treatment1 Intervention
IBPS participants will have their target weight adjusted each month by the study investigator based on recent assessment of intradialytic blood pressure slopes.
Group II: ControlActive Control1 Intervention
Participants in the control group will have their blood pressure, fluid status, as well as all other aspects of clinical care managed in entirety by their treating nephrologists.

Extracorporeal ultrafiltration (UF) is effective for short-term management of patients with congestive heart failure (CHF) who have severe fluid overload, leading to significant improvements in symptoms and quality of life.
Peritoneal dialysis (PD) may be more suitable for long-term treatment of CHF, but further research is needed to determine if these therapies can improve survival rates in patients with refractory CHF.

Ultrafiltration failure is a growing concern in patients on peritoneal dialysis, leading to increased cardiovascular risks and often resulting in the discontinuation of this treatment method.
This review highlights various strategies for preventing and treating ultrafiltration failure, emphasizing the importance of ongoing research to improve clinical outcomes for the increasing number of patients requiring renal replacement therapy.

In a study of 53 patients with intradialytic hypotension (IDH) and water retention, the combination of ultrafiltration (UF) and haemodialysis (HD) significantly improved treatment outcomes, including greater water removal and weight loss compared to conventional HD.
The sequential UF and HD treatment also resulted in a lower incidence of IDH (0% in the treatment group vs. 75% in the control group), indicating a safer approach for managing patients who struggle with dehydration and fluid overload.
