Protocol to Assess the Severity of Acute Kidney Injury (AKI)

This study has been completed.

The principal objective is to safely determine if we can identify the severity of Acute Kidney Injury (AKI) early in the course of the disease. Once enrolled, we will draw blood and urine for relevant biomarkers. Our goal is to validate if any of these biomarkers can predict the course of AKI (recovery v. RRT v. death)

Condition Intervention
Acute Kidney Failure Drug: Furosemide

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Protocol to Assess the Severity of Acute Kidney Injury

Primary Outcome Measures:
  • Patients meeting the definition for stage 3 of Acute Kidney injury as defined by the Acute Kidney Injury Network (AKIN-3) system. [ Time Frame: 14 days or discharge (whichever occurs first) ]

Enrollment: 44
Study Start Date: April 2008
Study Completion Date: December 2013
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: Furosemide
One dose: 1 mg/kg (iv)if the patient is furosemide naive or 1.5 mg/kg (iv) if patient is not furosemide naive.
Other Name: Lasix

Detailed Description:

AKI is a very common disease in the intensive care unit. However, despite advances in supportive care, patients with AKI carry a high mortality rate (50% to 70%). The established AKI affects nearly 5 percent of hospitalized persons and as many as 15 percent of critically ill patients. Currently, there are no FDA approved therapeutic agents for the treatment of AKI.

Retrospective studies suggest that the early initiation of renal replacement therapy (RRT) improves outcome. Many clinicians tend to take a "wait and see" approach because they do not want to dialyze a patient who is destined to recover renal function without the need for RRT. Therefore, it is vitally important to know early in the course which patients with AKI are likely to progress to RRT.

    • Defined by fractional excretion of Na of < 1% AND no evidence of the urinary casts, or
    • Patients that are under-resuscitated as deemed by treating clinical team or
    • Patients who are actively bleeding
  • Patients with a clinical syndrome of post-renal AKI

    • Any radiological study that shows hydro-ureter, or
    • Clinical scenario wherein the obstruction is considered a likely possibility of the cause of AKI
