|Hyperuricemia||Drug: Rasburicase Drug: Placebo||Phase 2|
The study will be a prospective, double-blind, placebo-controlled, randomized, clinical trial, initiated and implemented conjointly by the Nephrology and Cardiovascular Surgery Departments at Shands Hospital at the University of Florida in Gainesville, FL. We propose to study whether lowering uric acid provides significant renal and cardiovascular protection in subjects undergoing cardiovascular surgery. Up to 30 patients presenting for elective or urgent cardiovascular surgery with uric acid level > 6.5 mg/dl and estimated glomerular filtration of 30 - 60 ml/min will be included in the study. Patients recruitment will continue until up to 30 patients have completed the study, taking into account expected patient loss due to withdrawal of consent, incomplete study and other reasons.
Patients will be randomized to a control group or rasburicase group. Rasburicase or identical placebo will be administered to each group after randomization. A selected number of patients may undergo additional testing for mechanistic (non-clinical) secondary endpoints.

Active Comparator: Rasburicase
patients receiving rasburicase to lower serum uric acid
Rasburicase (Dose: 7.5mg in 50ml of normal saline administered over 30 minutes) or identical placebo will be administered as an (dosage form)intravenous infusion preoperatively.
Other Name: urate oxidase enzyme
Placebo Comparator: Placebo
patients will receive a placebo
Placebo drug (color-coded to appear identical to study drug) administered as an (dosage form) intravenous infusion preoperatively.
Other Name: inactive ingredient
- Number of Patients With Acute Kidney Injury (AKI). [ Time Frame: Within 48 hours postoperatively ]Acute kidney injury will be defined as an increase in serum creatinine of 0.3mg/dL from baseline or a 50% increase in serum creatinine from baseline values within 48 hours after surgery.
