Summary

The death rate of patients with endstage renal disease (ESRD) on dialysis each year is 20%, with diseases related to the heart and blood vessels causing about half. About 60% of patients on hemodialysis have high blood pressure, which is poorly controlled in most. Normal blood pressure in these patients greatly improves the chance of living. Increased fluid in the body and bloodstream is a major cause of hypertension in patients with ESRD. Fluid removal during hemodialysis is often limited by symptoms of low blood pressure during the procedure. Therefore the increase in fluid and related high blood pressure is ongoing for many of these patients. Arginine vasopressin (AVP) is a hormone naturally produced by the body which has little effect on blood pressure in healthy people, but acts as a powerful vasoconstrictor (narrows the blood vessels) when blood pressure is threatened. Recent studies have shown when there is too little AVP, patients are more likely to have low blood pressure during dialysis that limits fluid removal, an effect that can be reversed by giving these patients low doses of AVP. This phase II trial will find out which of two doses of AVP (.15 or .30 mU kg-1 min-1), in combination with standard therapy, works best to change interdialytic 44-hour ambulatory systolic blood pressure after 2 weeks. Patients who enroll in this study will be divided into three groups. One group will be given a 0.15 mU kg-1 min-1 dose of AVP at each dialysis session over a 2-week period; the second group will be given AVP 0.3 mU kg-1 min-1 at the same interval; and a third group will be given normal saline (placebo) at the same interval. All patients will be closely monitored for side-effects.

Conditions

Interventions

DRUG

Vasopressin - Very Low Dose

Intradialytic vasopressin (AVP) infusion. The dose is calculated based upon the individual's weight in kilograms. A kilogram is equal to 2.2 pounds. For example, a person who weighs 70 kg (or 154 pounds) would receive a dose equal to 0.15 mU \* 70 kg, or 10.5 mU of AVP per minute by infusion at their thrice-weekly dialysis treatments.

DRUG

Vasopressin - Low Dose

Intradialytic vasopressin (AVP) infusion. The dose is calculated based upon the individual's weight in kilograms. A kilogram is equal to 2.2 pounds. For example, a person who weighs 70 kg (or 154 pounds) would receive a dose equal to 0.30 mU \* 70 kg, or 21 mU of AVP per minute by infusion at their thrice-weekly dialysis treatments.

DRUG

Placebo Comparator

Participants in Group 3 will receive an equal volume of normal saline (placebo) infusion during their standard thrice-weekly dialysis treatments.
