About this study
Official title: Long Term Impact of Pediatric Acute Renal Injury in Severe Sepsis in Young Adults - IMPRESS YA
Sepsis is the most common cause of childhood death worldwide. Millions of children survive, but are left with impaired health. Sepsis-related Acute Kidney Injury (sAKI) is increasingly recognized as a significant factor associated with long-term mortality among different patient populations. Renal dysfunction and subsequent chronic kidney disease is implicated in the development of hypertension and cardiovascular disease. The investigators overall hypothesis is that, in the pediatric population, sepsis-related AKI will have unrecognized, long-term consequences with regard to kidney function, endothelial function, blood pressure control, and overall health.
Read the detailed description
This will be a two-arm cross-sectional control-cohort outpatient evaluation. Subjects with sAKI and a random selection of non-sAKI subjects who agree to participate in another study of quality of life survey will be asked to participate in the outpatient study. Subjects will be asked to come in to the Clinical Research Center for 24-hour monitoring and participate in the outpatient study where urinary and serum studies to measure glomerular filtration rate, renal plasma flow followed by blood pressure monitoring, peripheral arterial and applanation tonometry.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
IodohippurateDrug
Also called RPF filtration
An injection of non-radioactive iodohippurate (0.07 mL/kg) will be administered to determine renal plasma flow (RPF)
24 hour ambulatory Blood PressureProcedure or surgery
Ambulatory blood pressure (BP) monitoring will be performed using a commercially available device (TIBA Ambulo 2400) for 24 hours with measurements every 30 minutes while awake and every hour during sleep.
Peripheral Arterial TonometryProcedure or surgery
The peripheral arterial tonometry (PAT) device measures changes in the cutaneous circulation that correlate with flow-mediated dilatation.
Pulse Wave VelocityProcedure or surgery
Carotid-femoral and carotid-radial pulse wave velocities (PWV), validated markers of individual cardiovascular risk, will be determined by applanation tonometry using SphygmoCorVx technology (AtCor Medical). PWV is an index of the overall stiffness of a vascular segment between measurement sites 59. Thus, while carotid-femoral PWV is an index of the overall stiffness of proximal (central) arteries, the overall stiffness of peripheral arteries contributes relatively more to carotid-radial PWV.
GadoliniumDrug
Also called Magnevist Gadolinium (GD), Glomerular Function Rate (GFR) filtration
Magnevist Gadolinium (GD)-diethylene-triamine-pentaacetic acid-bis-oleate (0.07 to 0.14 mL/kg) will be used to determine GFR.
| Study group | Role | What they receive |
|---|---|---|
| Sepsis with Severe AKI | This group will have a history of pediatric admission with sepsis-related Acute Kidney Injury (sAKI) which lead to classification of "injury" or "failure". The following test will be performed: urinary and serum studies to measure glomerular filtration rate by using gadolinium, renal plasma flow by using an injection of non-radioactive iodohippurate, followed by cardiovascular assessments using 24 hour ambulatory blood pressure monitoring, peripheral arterial tonometry and pulse wave velocities (PWV). Receives: Drug: Iodohippurate; Procedure: 24 hour ambulatory Blood Pressure; Procedure: Peripheral Arterial Tonometry; Procedure: Pulse Wave Velocity; Drug: Gadolinium | |

What is being measured
The primary outcome is the main question the study is designed to answer.
Glomerular Function Rate (GFR) filtration
Magnevist Gadolinium (GD)-diethylene-triamine-pentaacetic acid-bis-oleate (0.07 to 0.14 mL/kg) will be used to determine GFR.
Measured: Day 2
Renal plasma flow (RPF) filtration
An injection of non-radioactive iodohippurate (0.07 mL/kg) will be administered to determine renal plasma flow (RPF) filtration.
Measured: Day 2
Proteinuria will be measured in the urine
Proteinuria may be a sign of renal (kidney) damage. Since serum proteins are readily reabsorbed from urine, the presence of excess protein indicates either an insufficiency of absorption or impaired filtration. People with diabetes may have damaged nephrons and develop proteinuria.
Measured: Day 2
Cystatin C will be measured in the blood
Cystatin C can be measured in a random sample of serum (the fluid in blood from which the red blood cells and clotting factors have been removed) using immunoassays such as nephelometry or particle-enhanced turbidimetry.
Measured: Day 2
Microalbuminuria will be measured in the urine
The level of albumin protein produced by microalbuminuria can be detected by special albumin-specific urine dipsticks. A microalbumin urine test determines the presence of the albumin in urine. In a properly functioning body, albumin is not normally present in urine because it is retained in the bloodstream by the kidneys.
Measured: Day 2
Secondary outcomes (3)
24 hour ambulatory Blood Pressure
Ambulatory blood pressure (BP) monitoring will be performed using a commercially available device (TIBA Ambulo 2400) for 24 hours with measurements every 30 minutes while awake and every hour during sleep.
Measured: 24 hours
Peripheral Arterial Tonometry
The peripheral arterial tonometry (PAT) device measures changes in the cutaneous circulation that correlate with flow-mediated dilatation.
Measured: 24 hours
Pulse Wave Velocity
Carotid-femoral and carotid-radial pulse wave velocities (PWV), validated markers of individual cardiovascular risk, will be determined by applanation tonometry using SphygmoCorVx technology (AtCor Medical). PWV is an index of the overall stiffness of a vascular segment between measurement sites 59. Thus, while carotid-femoral PWV is an index of the overall stiffness of proximal (central) arteries, the overall stiffness of peripheral arteries contributes relatively more to carotid-radial PWV.
Measured: 24 hours

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Kidney Injury and Chronic Kidney Disease, run by University of Florida.
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 10 inclusion and 8 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: withdrawn, as of the sponsor's last update on 27 Mar 2020. 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. 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 was withdrawn before enrolling participants, so there are no results.
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?
Glomerular Function Rate (GFR) filtration (time frame: Day 2). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 27 Mar 2020.
