Hydroxyethyl Starch and Renal Function After Laparoscopic Nephrectomy (VONE)

October 8, 2014 updated by: Erling Bjerregaard Pedersen, Regional Hospital Holstebro

Effect of Hydroxyethyl Starch on Renal Handling of Salt and Water, Blood Pressure-regulating Hormones, Proteins and Circulatory System of Patients Undergoing Kidney Removal by Keyhole Surgery

The purpose of this project is to investigate if hydroxyethyl starch (HES) is potential nephrotoxic and examine the effects on the circulation and kidneys during administration of HES during surgery.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Hydroxyethyl starch (HES) is widely used in hospitals to maintain circulation in critically ill patients. In recent years studies have raised suspicion that HES is nephrotoxic. So far acute kidney injury has been diagnosed based on creatinine measurements, but new technology allows for earlier diagnosis using measurements of biomarkers in urine. The purpose of this project is to investigate HES's potential toxicity and effects on the circulation and kidneys using measurements of biomarkers specific for toxicity and for the sodium/water balance in the urine and by measurements of vasoactive hormones in the blood after administration of HES 130/0.4

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
u-NGAL
Time Frame: 2-4 hours
The main objective for the trial(only patients undergoing elective laparoscopic nephrectomy) is to measure the effect of hydroxyethyl starch on u-NGAL, which is a biomarker of nephrotoxicity
2-4 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
u-Kim1 and u-LFABP
Time Frame: 2-4 hours
Another objective for the trial(only patients undergoing elective laparoscopic nephrectomy) is to measure the effect of hydroxyethyl starch on u-Kim1 and u-LFAPB, which are also biomarkers of nephrotoxicity
2-4 hours
FENa, u-ENaCβ, CH2O, u-AQP2,u-NCC, u-NK2CC
Time Frame: 2-4 hours
