(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)\n\nNGAL 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)"}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '20 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'all male and female patients with coronary artery disease who are recently exposed to PCI (20\\_70 years old )', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* patients exposed to percutaneous coronary intervention\n\nExclusion Criteria:\n\n* 1.Diabetes mellitus 2.Liver disease 3.Chronic Kidney Disease 4.Renal Replacement Therapy 5.Previous kidney transplant 6.Chronic infection'}, 'identificationModule': {'nctId': 'NCT03266367', 'briefTitle': 'Neutrophil Gelatinase Associated Liocalin in Predicting AKI in Coronary Artery Disease', 'organization': {'class': 'OTHER', 'fullName': 'Assiut University'}, 'officialTitle': 'The Role of Serum Neutrophil Gelatinase Associated Lipocalin in Predicting Acute Kidney Injury in Patients With Coronary Artery Disease', 'orgStudyIdInfo': {'id': 'NGAL in AKI'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'patients', 'description': 'NGAL and renal functions will be measured two hours after Percutaneous coronary intervention and two days later as a follow up', 'interventionNames': ['Diagnostic Test: Neutrophil gelatinase-associated lipocalin (NAGL)']}, {'label': 'Healthy Group', 'description': 'control group', 'interventionNames': ['Diagnostic Test: Neutrophil gelatinase-associated lipocalin (NAGL)']}], 'interventions': [{'name': 'Neutrophil gelatinase-associated lipocalin (NAGL)', 'type': 'DIAGNOSTIC_TEST', 'description': 'Serum level of Neutrophil gelatinase-associated lipocalin (NAGL) using the enzyme linked immunosorbent assay kits (ELISA)', 'armGroupLabels': ['Healthy Group', 'patients']}]}, 'contactsLocationsModule': {'centralContacts': [{'name': 'Basant R Mohamed, Dr', 'role': 'CONTACT', 'email': 'touch_my_heart12345@yahoo.com', 'phone': '01008669457'}, {'name': 'Zeinab A Abdelhamed', 'role': 'CONTACT', 'email': 'zeinabdoctor@yahoo.com', 'phone': '01003233267'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Assiut University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Resident Doctor', 'investigatorFullName': 'Bassant Rashad', 'investigatorAffiliation': 'Assiut University'}}}}
