Purpose
The purpose of this program of research is to determine whether curcumin, a natural health product, can prevent acute kidney injury and other complications after elective AAA repair. If proven safe and effective, curcumin is an inexpensive intervention which can be readily applied to almost 50,000 AAA repairs performed worldwide each year. New knowledge about this intervention may also guide its use in other surgical and medical settings to prevent complications to the kidneys, heart and other organs.

Primary Outcome Measures:
- Urine IL-18 [ Time Frame: Post op value ]We will examine the evidence of curcumin on biomarkers and whether it is well tolerated
- NT-ProBNP [ Time Frame: Change in post-operative minus pre-operative plasma NT-Pro BNP ]
- hsCRP [ Time Frame: Change in post-operative minus pre-operative plasma hsCRP ]
- Serum creatinine [ Time Frame: Change in peak post-operative serum creatinine (umol/L) in the 7 days following AAA repair minus pre-op value ]
Secondary Outcome Measures:
- Binary measures of continuous biomarker outcomes [ Time Frame: Continuous ]e.g acute kidney injury defined using accepted criteria
- Safety outcomes [ Time Frame: Peri-operative period ]Anemia, hypoglycemia, diarrhea, bleeding, peptic ulcer, nausea
- Composite clinical outcomes adjudicated by investigators unaware of treatment outcomes [ Time Frame: Within 30 days of AA repair ]New acute dialysis, myocardial infarction, receipt of coronary revascularization, sepsis, pneumonia, non-fatal cardiac arrest, stroke, deep vein thrombosis, pulmonary embolism, lower limb amputation, ischemic bowel, congestive heart failure, death
Other Outcome Measures:
- Other outcome measures [ Time Frame: Peri-operative period ]Study medication adherence, length of hospital stay, pain, blood pressure 3 hours after repair, urine output 3 hours after repair, other urine and blood biomarkers, tracer outcomes

Experimental: curcumin
Patients will take the study medication (500 mg x 4 capsules, twice daily [BID]) for two days leading up to repair, totaling 4000 mg per day. They will take a dose (2000 mg) the morning of repair, at the same time as regular medications not held for surgery. While they are on call to the operating room, they will take another dose of 2000 mg., and then another 2000 mg dose 6 hours after the repair. Final dose (2000 mg)is administered morning after repair.

Detailed Description:
An abdominal aortic aneurysm (AAA) is a ballooning of the abdominal aorta, the major blood vessel of the body. AAA occurs in up to 2% of adults. Surgeons will plan an AAA repair when the aneurysm grows bigger than 5.5cm, because the AAA might burst without repair. Over 47,000 AAA repairs are performed each year. Despite the benefits of AAA repair there are risks, and the kidneys can be severely injured. We will test whether the natural health product curcumin has an effect on biomarkers of inflammation, kidney injury and heart injury from AAA repair. Curcumin appears to fight oxidation and inflammation, which are ways that the body can be injured by surgery. We will study 600 patients who have elective AAA repair. The patients will receive either curcumin or a matching placebo. We will recruit the 600 patients from 10 centres in Ontario. This study will help us determine whether curcumin exerts any biological effect on biomarkers and whether it is well tolerated. If there is evidence of beneficial effects in this 600 patient trial, this will justify a future larger trial to assess the effects of curcumin on outcomes most important to patients, families and their healthcare providers.
