Association between preoperative statin use and acute kidney injury biomarkers in cardiac surgical procedures.

چکیده
BACKGROUND Acute kidney injury (AKI) is a serious complication of cardiac operations for which there remains no specific therapy. Animal data and several observational studies suggest that statins prevent AKI, but the results are not conclusive, and many studies are retrospective in nature. METHODS We conducted a multicenter prospective cohort study of 625 adult patients undergoing elective cardiac operations. All patients were taking statins and were grouped according to whether statins were continued or held in the 24 hours before operation. The primary outcome was AKI as defined by a doubling of serum creatinine or dialysis. The secondary outcome was the peak level of several kidney injury biomarkers. The results were adjusted for demographic and clinical factors. RESULTS Continuing (vs holding) a statin before operation was not associated with a lower risk of AKI, as defined by a doubling of serum creatinine or dialysis (adjusted relative risk [RR] 1.09; 95% confidence interval [CI] 0.44, 2.70). However, continuing a statin was associated with a lower risk of elevation of the following AKI biomarkers: urine interleukin-18, urine neutrophil gelatinase-associated lipocalin, urine kidney injury molecule-1, and plasma neutrophil gelatinase-associated lipocalin (adjusted RR 0.34; 95% CI 0.18, 0.62), (adjusted RR 0.41; 95% CI 0.22, 0.76), (adjusted RR 0.37; 95% CI 0.20, 0.76), (adjusted RR 0.62; 95% CI 0.39, 0.98), respectively. CONCLUSIONS Statins may prevent kidney injury after cardiac operations, as evidenced by lower levels of kidney injury biomarkers.

متن کاملHigh‐Density Lipoprotein Cholesterol Concentration and Acute Kidney Injury After Cardiac Surgery
BACKGROUND Acute kidney injury (AKI) after cardiac surgery is associated with increased short- and long-term mortality. Inflammation, oxidative stress, and endothelial dysfunction and damage play important roles in the development of AKI. High-density lipoproteins (HDLs) have anti-inflammatory and antioxidant properties and improve endothelial function and repair. Statins enhance HDL's anti-inf...

Cardiac surgery associated acute kidney injury (CSAAKI) is a considerable complication with the incidence of 8.9%-39% according to current studies (1-10). It is the second cause of acute kidney injury (AKI) development in the intensive care patients at er sepsis, as well as an independent risk factor for mortality (11-13). Although the incidence of postoperative AKI development is higher in pat...
متن کاملDuration of cardiopulmonary bypass is an important confounder when using biomarkers for early diagnosis of acute kidney injury in cardiac surgical patients
Objectives: Acute kidney injury is an important complication in patients undergoing cardiac surgery. Recently, several biomarkers to facilitate early detection of acute kidney injury have been proposed, among them Neutrophil-gelatinase-associated-lipocalin, Kidney-injury-molecule-1, and LFatty-acid-binding-protein. The expression of these markers is increased by ischemia-reperfusion injury and ...
