Primary Outcome Measures:
  • Number of dialysis complicated by at least one hypotension [ Time Frame: six months ] [ Designated as safety issue: No ]

    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

Secondary Outcome Measures:
  • Blood Pressure Intradialytic symptoms [ Time Frame: six months ] [ Designated as safety issue: No ]
    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.

Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Standard
Standard constant (no profiled) sodium dialysate used during endogenous hemodiafiltration
Device: Standard sodium dialysate
Standard constant (no profiled) sodium dialysate used during endogenous hemodiafiltration
Other Name: Standard HFR
Experimental: Automated profiled
Automate sodium profiling in 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.
Other Name: HFR-Aequilibrium

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.
