About this study
Official title: The Role of Serum Neutrophil Gelatinase Associated Lipocalin in Predicting Acute Kidney Injury in Patients With Coronary Artery Disease
The aim of this work is to assess the clinical significance of serum levels of neutrophil gelatinase-associated lipocalin (NGAL) to predict AKI in patients exposed to PCI.
Read the detailed description
ST-elevated myocardial infarction(STEMI) patients are at a particularly high risk of acute kidney injury (AKI) because of the complexity of hemodynamic disorders and adverse effects associated with the use of radiopaque diagnostic and treatment methods (Smirnov AV.et al.,2009) With wide application of percutaneous coronary intervention (PCI) technology in patients with coronary artery disease (CAD), contrast-induced acute kidney injury (CI-AKI) has become a serious complication and is the third leading cause of AKI in hospitalized patients.(Gleeson.et al. 2004)
To date,AKI diagnosis has been limited to observation of increasing levels of serum creatinine,decrease in urine output,and alterations in urinary chemistry (Bellomo.et al.2004;Mehta.et al. 2007) Nevertheless,serum creatinine levels do not increase significantly until renal function has decreased to 50% in addition,the level of serum creatinine may be affected by the patient's muscle mass,catabolic state,protein intake,weight,sex and tubular secretion of creatinine.Therefore,applying serum creatinine as a biomarker for diagnosing AKI may result in the loss of valuable time (Mishra.et al.2005;Sirota.et al.2011)
Neutrophil Gelatinase-associated lipocalin(NGAL) belongs to the lipocalin family and is produced predominantly by the liver and white blood cells(Hvidberg.et al.,2005).
A small polypeptide, neutrophil gelatinase-associated lipocalin (NGAL), is one of the most promising and best-studied AKI biomarkers (Mishra.et al.,2003; Devarajan.et al 2003) The expression of NGAL was predominantly in proliferating and regenerating tubular epithelial cells, which suggested a role in repair. (Mori.et al.2005) The majority of NGAL, secreted by injured renal tubule epithelial cells, is in a 25kDa monomeric form. In contrast, neutrophils have been claimed to release NGAL primarily as a 45kDa homodimer, i.e. two NGAL monomers linked by a disulfide bridge. It also exists as a 135-kDa heterodimer, covalently conjugated with gelatinase (Cai.et al.2010) NGAL is easily detected in blood and urine due to its small size and resistance to degradation. It can be measured non-invasively using routine laboratory analysers as well as some point of care devices. Furthermore, NGAL concentration in both urine and plasma rises rapidly in a dose-dependent manner that is proportional to the degree of acute kidney damage (Haase-Fielitz.et al.2009)
NGAL has previously been termed the 'troponin-like' biomarker to detect subclinical AKI even in the absence of diagnostic increases in SCr (Devarajan.,2010;Haase,et al.2011) Additionally, NGAL has been reported to be predictive 48 h prior to the actual time of injury; therefore, renal replacement therapy can be planned earlier(Cruz,et al.2010)

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Kidney Injury, run by Assiut University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 5 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Basant R Mohamed, Dr (01008669457, touch_my_heart12345@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The rise of NGAL in AKI after PCI before rise of renal function (time frame: 2 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03266367, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2017.
