Summary

Acute Kidney Injury (AKI) is a common and severe complication in critically ill patients which is associated with increased morbidity and mortality as well as high costs of medical care.

NGAL (neutrophil gelatinase-associated lipocalin, lipocalin-2, siderocalin) is a biomarker, that is expressed in several tissues including the kidneys. Renal expression of NGAL is dramatically increased in kidney injury from a variety of causes, and NGAL is released into both urine and plasma. NGAL levels rise within two hours of the insult, making NGAL an early and sensitive biomarker of kidney injury, with the potential to assist clinicians in managing patients at risk of kidney injury.

This study is designed to validate the assigned NGAL cutoff value by comparing to clinical diagnosis of AKI as determined by current clinical practice in the US.

The study sites will enroll consecutive ICU patients. Patients are given standard clinical care and lab-work. Each day, one additional urine and two additional plasma samples will be drawn and frozen. These additional samples are shipped to Sponsor for retrospective NGAL measurements.

The duration of each subject´s participation will be until discharge from the ICU, or for a maximum 8 days, whichever comes first. In addition serum creatinine values will continue to be collected manually from the hospital data system for 48 hours after discharge from the ICU. (If subject has been in ICU for 8 or more days, the follow up values are collected while the patient is still in the ICU).

250 subjects will be enrolled in total at the three investigator sites. At least 40 patients must be enrolled at each site.

The NGAL value will be matched to the "clinical diagnosis" of acute kidney injury (AKI) as specified by KDIGO® guidelines. The clinical diagnosis will be assigned by a three-person adjudication panel based on the entries in the eCRF by the investigators. Adjudicators are blinded for investigation site, AKI-diagnosis by treating physician, and NGAL values.

A comparison of AKI diagnosis based on the cutoff value 250 ng/mL and clinical diagnosis as assigned by the majority of the adjudication panel will be conducted.
