Volume,Sodium and Blood Pressure Management in HD — VSBP  

End Stage Renal Failure Clinical Trial

Official title:
Fluid-Weight, Volume, Sodium, Blood Pressure Management in Hemodialysis by Limiting Intradialytic and Inter-dialytic Exposure to Sodium and Protocol-based Challenge of Post-dialysis Target Weight: A Pilot and Feasibility Trial

Clinical Trial Summary

The purpose of this study to conduct a pilot, randomized trial in stable HD patients to evaluate the effect of gradual, step-wise reduction of post-hemodialysis target weight, combined with diligent dietary sodium restriction and reduction in dialysate sodium exposure on hydration/volume status and blood pressure (BP) control.

Clinical Trial Description

Fluid-weight management is critical for dialysis patients 1, 2. Previous clinical trials have not comprehensively addressed the application of a strategy combining both sodium restriction and a progressive, but gradual challenge of post dialysis target weight for BP and fluid-weight management in hemodialysis (HD). The investigators postulate that a protocolized, stepwise and gradual challenge of post-hemodialysis target weight when combined with diligent dietary sodium restriction <2000mg sodium/day, will lead to better hydration/volume status and BP control in HD patients. A randomized, two parallel arm trial (n=40) among HD patients is proposed, that compares this comprehensive strategy in one group versus 'usual' HD volume/hydration and BP management in the control group. The two primary outcomes are change in volume/hydration status (assessed by bioelectrical impedance analysis-BIA) and change in BP (pre-dialysis in-center readings, home self-monitored readings as well as 44-hour interdialytic BP). Secondary outcomes include change in target post-dialysis weight, slope of on-line relative plasma volume monitoring (using Crit-line monitors), utilization and change, if any, in antihypertensive regimen, change in interdialytic weight gain, objectively assessed salt-appetite, thirst score, frequency of intradialytic hypotension, cramps and duration of post-dialysis fatigue and recovery, time to achievement of dry weight and laboratory parameters (hemoglobin, albumin, brain natriuretic peptide-BNP, aldosterone and hsCRP). The trial will be 14-weeks in duration and will involve comprehensive assessment of study parameters at baseline, middle and end of the trial. It is anticipated that the trial will lead to the the development of a simple and practical approach for volume and BP control in HD patients that will subsequently need to be studied on a larger scale, i.e., a larger, multicenter study with hard endpoints of death and hospitalization. ;
