About this study
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
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.
Read the detailed 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lower sodium interventionBehavioural
- Lower sodium intervention:
- Dietary sodium restriction of ≤2.0 g/day or ≤85 mmol/day (approximately >180-200mmol/day in the average American diet). Sodium restriction will be implemented using intensive dietary counseling performed weekly by a registered study dietitian using the motivational interviewing technique.
- Lower dialysate sodium at 137 mmol/L, if perchance a different concentration of dialysate is used for the enrolled individual, although this is unlikely in both the UM associated units, where for some time now, dialysate concentration of 137 mmol/L is currently being used as standard practice. Investigators will ensure that this sodium concentration is indeed used for all study participants.
Progressive Challenge to Post Dialysis WeightOther
The existing target post-HD weight will be progressively challenged by removing additional fluid in small increments, unless clinical evidence of volume depletion or hypotension precludes this challenge in the intervention arm. To avoid the occurrence of intradialytic hypotension, the ultrafiltration rate shall not exceed15 ml/kg/hour and post dialysis weight will not be reduced by more than 0.5 kg per dialysis session. In some patients, this may warrant prolongation of the treatment time to achieve lowering of target post dialysis weight, and this process of target weight reduction may need to continue up to and through the interim assessment phase (6-8 weeks).
| Study group | Role | What they receive |
|---|---|---|
| Treatment | Experimental | 1. Lower sodium intervention:
Dietary sodium restriction of ≤2.0 g/day or ≤85 mmol/day
Lower dialysate sodium at 137 mmol/L.
2. Progressive Challenge to Post Dialysis Weight:
The existing target post-HD weight will be progressively challenged by removing additional fluid in small increments. Receives: Behavioral: Lower sodium intervention; Other: Progressive Challenge to Post Dialysis Weight |
| Control | No intervention | Usual care in addition to Blood pressure monitoring and and Hydration status monitoring |

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?
Blood Pressure (time frame: Pre-dialysis BP measure at Baseline, 6 Weeks and 12 weeks. ABPM measured at baseline and 12 Weeks. Home BP measure through out the 12week period on non-dialysis days). 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 NCT01766882, which also lists 16 linked publications.
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 15 Jul 2016.
