About this study

Official title: The Effect of Low Sodium Dialysate on Ambulatory Blood Pressure Measurement Parameters in Patients Undergoing Hemodialysis

End stage renal disease (ESRD) is related with increased cardiovascular mortality and morbidity. Hypertension (HT) is an important risk factor for cardiovascular disorder among hemodialysis (HD) patients. The aim of this study going to investigate the effectivity of low-sodium dialysate on the systolic and diastolic blood pressure (BP) levels detected by ABPM and interdialytic weight gain (IDWG) in patients undergoing sustained hemodialysis treatment.

Methods: The study will be included 46 patients who had creatinine clearance levels less than 10 ml/min/1.73 m2 and had been on chronic HD treatment for at least one year. After the enrollment stage, the patients will be allocated low-sodium dialysate or standard-sodium dialysate for six months via computer-generated randomization.

Read the detailed description

Patient Selection The present study is a single-center, randomized controlled and double blinded trial. The patients going to enroll for this study had creatinine clearance less than 10 ml/min/1.73 m2 and had been on intermittent HD treatment for at least one year.

The exclusion criteria for the present study are masking or white coat hypertension, heart failure, cardiomyopathies, acute coronary syndromes, chronic ischemic heart disease, acute or chronic liver disease, endocrine or pulmonary diseases, valvular heart diseases, malignancies, active urinary tract infections, hemoglobin levels below 8 g/dL, and hypotension tendency.

Sixty-four patients going to enroll for eligibility and after the initial assessment. Clinic and laboratory profiles of the patients including cause of renal disease, history of HT and antihypertensive treatments going to record by systematic review of the patient files. After the enrollment stage, the patients going to allocate low-sodium dialysate or standard sodium dialysate for 6 months via computer-generated randomization.

They going to dialyze three times a week with synthetic polysulfone (Hollow-fiber, Low Flux, KUF<20, 1.6 m2) membrane, each session lasting 4 hours with bicarbonate dialysate (with 33mmol/L concentration) and 300-350 ml/min blood-flow. .

Study protocol All patients going to assess before and 6 months after the study. Before initiating the study, all patients were dialyzed with 140 mEq/L sodium concentration. In the low-sodium dialysate group, the dialysate sodium concentration going to reduce from 140 to 137mEq/L. To eliminate the acute effects of hemodialysis on the parameters measured, baseline and end-of-study measurements going to perform in non-dialysis day, 24 hours after the mid-week session.

Ambulatory blood pressure measurement Ambulatory BP measurement during 24-hour going to perform using a Space Labs 90207 oscillometric method (Redmond, Washington, USA). The BP measurements going to perform automatically from non-fistula arm. The confirmation of the device going to check with the standard auscultator method in order to ensure that the changes in BP values between the two methods did not exceed +5 mm Hg.

The device going to set to achieve BP evaluation at 30-minute intervals during the night (11:00 PM to 07:00 AM) and at 20-minute intervals during the day (07:00 AM to 11:00 PM).

''Nocturnal dipping'' going to define as a decrease of greater than 10% (when compared with the daytime values) in the systolic or diastolic blood pressure at night. ''Non-nocturnal dipping'' going to define as a decrease of less than 10% (when compared with the daytime values) in the blood pressure parameters levels at night or did not decrease in the systolic or diastolic blood pressure at night

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 10 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Ambulatory blood pressure measurement (time frame: six months). 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 NCT02621450, which also lists 2 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?
