Does Nesiritide Provide Renal Protection
Study Details
Study Description
Brief Summary
This project evaluates whether nesiritide, human recombinant brain natriuretic peptide, confers renal protection during cardiovascular surgery by attenuating the inflammatory response.
Condition or Disease | Intervention/Treatment | Phase |
---|---|---|
|
Phase 2 |
Detailed Description
This will be a randomized, prospective blinded pilot study comparing nesiritide to placebo in patients undergoing aortic arch, ascending aorta, aortic valve or mitral valve surgery with baseline GFR 30-90ml/min. Patients were randomized to either placebo or nesiritide (administered prophylactically starting in the operating room prior to incision at 0.01 mcg/kg /minute with no bolus and continued for 48 hours).

Outcome Measures
Primary Outcome Measures
- Measure Neutrophils to Measure Kidney Injury [30 days from the start of infusion]
0.35 mL of whole blood from each patient was applied to a microfluidics chip to isolate neutrophils. Total RNA was subsequently isolated and gene expression (for all genes listed below) was measured with an Affymetrix gene chip. Data was normalized using RMA (Robust multi-array average) and expressed as log2 expression.
- The Examine and Measure Cytokines to Measure Kidney Injury [30 days from the start of infusion]
Serial measurement of serum cytokine profiles were measured with multiplex Luminex plates that enable the simultaneous measurement of 23 cytokines.
- The Examine and Measure Endothelin-1 to Measure Kidney Injury [30 days from the start of infusion]
Serial measurements of Endothelin-1 levels were measured to determine if natriuretic peptides exert their renal protective effects by preserving renal afferent arteriole flow by antagonizing the vasoconstrictive effects of Endothelin-1.
- The Examine and Measure Urinary NGAL to Measure Kidney Injury [A change in urinary NGAL 2 hours after bypass was stopped and 5 minutes after the start of spontaneous circulation was resumed.]
Urinary NGAL,a biomarker for kidney injury was measured.

Study Results
Participant Flow
Recruitment Details | Starting in June 2010 and ending in December 2012, subjects were seen in outpatient clinics or in the hospital. The pre-operative labs were used to screen and enroll subjects. |
---|---|
Pre-assignment Detail | Out of the 37 signed informed consent there were 8 subjects who were consented and did not participate: 2 subjects changed their mind, 5 subjects creatinine level was not within the protocol level for participation, 1 subject surgery was canceled. This left 29 subjects to participate in the study. |

Title | The Examine and Measure Endothelin-1 to Measure Kidney Injury |
---|---|
Description | Serial measurements of Endothelin-1 levels were measured to determine if natriuretic peptides exert their renal protective effects by preserving renal afferent arteriole flow by antagonizing the vasoconstrictive effects of Endothelin-1. |
Time Frame | 30 days from the start of infusion |
