HFR A-equilibrium on Cardiovascular Stability (AIMS)

August 26, 2011 updated by: Francesco Locatelli, Azienda Ospedaliera di Lecco

Randomized Controlled Study on the Effect of the Hemodiafiltration Plasma Sodium Biofeedback System on Cardiovascular Stability in Hemodialysis Patients

Aim of the present randomized controlled multinational trial is the comparison of a novel biofeedback system on sodium profiling applied to a endogenous hemodiafiltration therapy, with the standard (no sodium profiling) hemodiafiltration technique on the intradialytic overall and cardiovascular stability.

Detailed Description

Online hemodiafiltration (OL-HDF) has been recently associated with better patient survival in comparison with standard hemodialysis in some large observational studies (Canaud et al, KI, 2006; Vilar et al, CJASN , 2009) supporting the hypothesis that convection can improve patients outcomes. Moreover, it has been demonstrated in randomized controlled trials (Locatelli et al, Journal American Society of Nephrology, 2010) that OL-HDF significantly reduced the frequency of intradialytic hypotension. Nonetheless, the associated comorbidities and ageing of dialysis population require further devices able to improve treatment tolerance. Among these tools, the sodium profiling and biofeedback system seem to be promising to accomplish this task. But the correct intradialytic sodium balance is still far away today to be easily achieved. The use of an automated adaptive system dialysis to the sodium profiling has been investigated in a feasibility trial (Colì et al International Journal Artificial Organs, 2003). They also investigated the impact of such a device on treatment tolerance.

The aim of this randomized multinational multicenter controlled trial is to evaluate the impact of sodium profiling applied to a endogenous hemodiafiltration technique on the intradialytic cardiovascular stability in comparison to standard no profiled endogenous hemodiafiltration.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Active Comparator: Standard
Standard constant (no profiled) sodium dialysate used during endogenous hemodiafiltration

Device: Automated sodium profiling in endogenous hemodiafiltration
Automated sodium profiling during endogenous reinfusion hemodiafiltration technique. The device processes the dialysate sodium and ultrafiltration rate during dialysis to achieve a preset sodium target at the end of the treatment. Sodium dialysate and maximal ultrafiltration rate are constraint within safety limits during dialysis.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of dialysis complicated by at least one hypotension
Time Frame: six months

Hypotension definition:

If predialysis systolic blood pressure greater than100 mmHg then a value during dialysis below 90 mmHg or any systolic blood pressure reduction greater than 25 mmHg in presence of symptoms or If predialysis systolic blood pressure less than 90 mmHg a reduction of at least 10% accompanied by symptoms
six months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Blood Pressure Intradialytic symptoms
Time Frame: six months
Systolic, diastolic blood pressures (SBP, DBP) and heart rate (HR) measured at the beginning of each treatment and every 30 minutes till the end of dialysis; intradialytic symptoms (nausea, vomiting, hypotension, headache, cramps) and related clinical interventions.
