Long Term Impact of Pediatric Acute Renal Injury in Severe Sepsis

Withdrawn

• Conditions: Acute Kidney Injury; Hypertension; Chronic Kidney Disease

• Registration Number: NCT02372721
• Lead Sponsor: University of Florida

Brief Summary

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.

Detailed Description

This will be a three-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.

Exclusion Criteria

For all patients:

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Chronic Kidney Disease	Day 2	Obtaining preliminary estimates of glomerular function, renal plasma flow, proteinuria, cystatin C and microalbuminuria in children with and without a history of acute kidney injury in order to assess the presence of chronic kidney disease.

Secondary Outcome Measures

Name	Time	Method
Hypertension	24 hours	Ambulatory blood pressure (BP) monitoring, peripheral arterial and applanation tonometry will be performed. A subject will be considered hypertensive if systolic and/or diastolic blood pressure is \>95th percentile for sex, age, and height.
