Official title
Inhibition of Lipid Peroxidation During Cardiopulmonary Bypass
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Acute kidney injury is a major complication of cardiac surgery requiring cardiopulmonary bypass (CPB). Hemolysis and rhabdomyolysis frequently occur during CPB. Hemolysis leads to an increase in free hemoglobin, whereas rhabdomyolysis leads to an increase in myoglobin. Free plasma hemoglobin and myoglobin have been shown to be independent predictors of the acute kidney injury that results from CPB. When these hemeproteins are released into the plasma, they undergo redox cycling, generating radical species that initiate lipid peroxidation and a cascade of oxidative damage to cellular membranes, notably in the kidney. F2-isoprostanes and isofurans are sensitive and specific markers of oxidative stress in vivo, and are increased after CPB, particularly in those patients with acute kidney injury. Acetaminophen inhibits the lipid peroxidation catalyzed by myoglobin and hemoglobin. Moreover, in an animal model of rhabdomyolysis-induced kidney injury, acetaminophen significantly attenuated the decrease in creatinine clearance compared to control. The current proposal tests the central hypothesis that acetaminophen will attenuate the lipid peroxidation associated with the hemolysis and rhabdomyolysis that occur in patients undergoing CPB. Demonstration that acetaminophen inhibits the lipid peroxidation resulting from CPB would provide a rationale for a prospective randomized trial to test the hypothesis that acetaminophen will reduce the acute kidney injury that results from CPB.
