Diagnosis of acute kidney injury (AKI) relies on a late marker, namely serum creatinine (SCr). New biomarkers are considered for early and sensitive detection of CIN. In particular, uNGAL has been used for early detection of AKI in the emergency department, after cardiopulmonary bypass or following CM administration.

This study will be conducted to assess the possible value of urinary Neutrophil Gelatinase-Associated Lipocalin (uNGAL) as an early detector of contrast-induced nephropathy (CIN) in a large sized cohort of patients undergoing percutaneous coronary procedures (PCP) and whether or not uNGAL correlates with the volume of contrast medium (CM) used.

Official Title: Is Urinary Neutrophil Gelatinase-Associated Lipocalin (uNGAL) the "Renal Troponin" in Invasive Cardiology?

Further study details as provided by University of Freiburg:

Primary Outcome Measures:
  • to assess the value of uNGAL measurement 4 to 6 hours after PCP as a possible early detector of CIN [ Time Frame: 4-6 hours after PCP ] [ Designated as safety issue: No ]
    cf title

Secondary Outcome Measures:
  • to study the relationship between the volume of contrast medium used for PCP and the uNGAL levels measured 4 to 6 hours thereafter [ Time Frame: 4-6 hours after PCP ] [ Designated as safety issue: No ]

Estimated Study Completion Date: February 2013
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
consecutive, PCP patients
All patients requiring percutaneous coronary procedures, such as coronary angiography or intervention

Detailed Description:

Methods. We will enroll all consecutive patients undergoing PCP with iomeprolum during a 3-month period at our institution. CIN will be defined as a ≥25% increase in SCr from baseline when measured 2-4 days after PCP. uNGAL will be measured at its peak with the Abbott ARCHITECT assay.
