Renin Angiotensin Aldosterone System In Septic Kids

Recruiting
Conditions
Acute Kidney Injury (Nontraumatic)
Sepsis
Acute Kidney Injury Due to Sepsis
Registration Number
NCT06295393
Lead Sponsor
Northwell Health
Brief Summary

Prospective observational cohort study; pediatric sepsis vs. healthy pediatric subjects and pediatric sepsis with acute kidney injury (AKI) vs without AKI.

Blood samples and renal ultrasound will be collected on sequential days for septic subject and one time for the healthy patients.

Enzyme-linked immunosorbent assays (ELISA) with be run on serum plasma to compare the renin-angiotensin-aldosterone system (RAAS) between groups.

Detailed Description

Prospective observational cohort study; pediatric sepsis vs. healthy pediatric subjects and pediatric sepsis with AKI vs without AKI.

Powered to collect 74 patients total (37 sepsis,37 healthy) with enrollment ratio 1:1 and expected different of 50% in renin levels, this provides 80% power at an alpha of 0.05.

Sepsis identified as pediatric Sequential Organ Failure Assessment (pSOFA) \>/= 2 + infection and/or Phoenix sepsis criteria.

Collecting blood samples on subsequent days of hospitalization. For healthy patients, a one-time blood draw will be obtained .

Renal ultrasound will be performed on day 1, 2 and 3 of hospitalization.

Blood will be collected and plasma stored at -80 degrees Celsius.

Plasma thawed in batches and ELISAs for RAAS components.

Demographic data will be collected.

NameTimeMethod
Difference in serum renin in sepsisFor sepsis cohort point 1 collection within the first 48 hours from of meeting sepsis criteria, point 2: 48-72 hours and point 3: 72-94 hours. For the healthy cohort blood drawn at a single time point up to 24 hours

Comparison between healthy and septic subjects serum renin levels

Secondary Outcome Measures
