ACE gene polymorphisms are known to influence serum angiotensin converting enzyme level. Contrast nephropathy develops after exposure to intravascular contrast media that influence vascular hemodynamics. ACE gene polymorpisms may have an enhancing role in contrast media related renal injury. The aim of the study: The aim of this study was to investigate the impact of ACE insertion/deletion (I/D) polymorphism in contrast-induced nephropathy (CIN) development. Methods: 194 patients with chronic kidney disease that were administered iodinated contrast media were examined. Patients were monitored for at least 7 days for CIN development after parenteral contrast exposure. Control and patient groups were divided in terms of CIN development status. Polymerase chain reaction was performed for the genotyping of the ACE gene polymorphism from DNAs that were isolated from peripheral blood of the patients. Results: 83 patients with CIN (34 women, 49 men) and 111 control patients without CIN (43 women, 68 men) were enrolled. Gender was not statistically different between the two groups (p = 0.75). The average age of the CIN group (71) was greater than that of the control group (68). No association was detected between ACE gene polymorphism (II, ID AND DD genotypes) and CIN in both patients and controls. Conclusion: ACE gene polymorphisms does not influence contrast induced nephropathy development.en10.1016/j.mgene.2021.100992info:eu-repo/semantics/closedAccessContrast NephropathyRenal FailureGene PolymorphismPolymerase Chain ReactionAngiotensin-Converting-EnzymeInsertion-Deletion PolymorphismCoronary-Artery-DiseaseEndothelial DysfunctionKidney-DiseaseAssociationProgressionGenotypeLinkageRiskArticle31N/AWOS:0007203427000092-s2.0-85118592128Q4
