Angiotensin-Converting Enzyme Polymorphism and Acute Renal Failure (ECAREA)

Evaluation of the Impact of the Angiotensin-Converting Enzyme Insertion/Deletion Polymorphism on the Development of Acute Renal Failure in Critically Ill Patients

Associations between angiotensin-converting enzyme gene polymorphism and occurrence and outcome of ARDS, and with respiratory complications post cardiopulmonary bypass have already been demonstrated. Based on physiological effects of angiotensin II, we hypothesized that the I allele of the angiotensin-converting enzyme Insertion/Deletion polymorphism may be associated with a higher risk of acute renal failure in critically ill patients.
