Mitochondrial injury contributes to renal dysfunction in several models of renal disease, but its involvement in human hypertension remains unknown. Fragments of the mitochondrial genome released from dying cells are considered surrogate markers of mitochondrial injury. We hypothesized that hypertension would be associated with increased urine mitochondrial DNA (mtDNA) copy numbers. We prospect...

The aim of the present study was to analyze the diagnostic value of neutrophil gelatinase-associated lipocalin (NGAL) in renal injury in asphyxiated preterm infants. In total, 48 cases of asphyxiated preterm infants, 45 cases of premature infants and 45 cases of normal newborn infants were included in the study. Using ELISA we evaluated the level of urine NGAL, kidney injury molecule-1 (KIM-1),...

INTRODUCTION Preoperatively elevated serum creatinine (SCr) is considered an independent risk factor for morbidity and mortality after cardiac surgery. The aim of this study was to apply the Kidney Disease Improving Global Outcomes classification for acute kidney injury in a population of patients with preoperatively elevated serum creatinine who underwent cardiac surgery (coronary artery bypas...

BACKGROUND In patients with heart failure, renal dysfunction is associated with a poor outcome. We aimed to assess the prognostic value of plasma neutrophil gelatinase-associated lipocalin (NGAL), a novel marker of renal tubular damage, in patients with heart failure with or without renal dysfunction, and compare it with 2 frequently used biomarkers of chronic kidney disease. METHODS AND RESU...

background: l-carnitine may prevent the incidence of aki by its antioxidant effects and improving circulation in ischemic conditions. the goal of this trial was to evaluate the impact of l-carnitine on contrast-induced nephropathy in patients undergoing elective pci. methods: totally, the patients were randomly allocated to 2 groups. the treatment group received 1 g of l-carnitine orally 3 time...

Background: Acute kidney injury (AKI) is a common problem in critically ill patients and is independently associated with increased morbidity and mortality. Recently, serum cystatin C has been shown to be superior to creatinine in early detection of renal function impairment. We compared estimated GFR based on serum cystatin C with estimated GFR based on serum creatinine for early detection of ...

Purpose. Contrast-induced nephropathy (CIN) can contribute to acute kidney injury (AKI) in patients undergoing endovascular aortic aneurysm surgery. We evaluated the incidence of AKI together with the evolution of early biomarkers of renal injury in patients receiving bicarbonates or NaCl 0.9%. Methods. This study involved endovascular aortic aneurysm surgery patients. Group A (n = 17) received...

OBJECTIVE The objective of this study was to evaluate whether remote ischemic preconditioning can protect kidney function in children undergoing operation for complex congenital heart disease. METHODS Children (n = 113) aged 0 to 15 years admitted for complex congenital heart disease were randomly allocated according to age to remote ischemic preconditioning and control groups. After exclusio...

OBJECTIVES To explore the correlation between serum cystatin C level and elderly hypertension with coronary heart disease patients. METHODS 500 hypertensive patients combined coronary heart disease were selected by coronary angiography. 321 of them were elderly patients with hypertension (male 204, female 117), and 400 of them were elderly patients with coronary heart disease (male 257, femal...

BACKGROUND Acute kidney injury (AKI) following cardiac surgery is a major complication resulting in increased morbidity, mortality, and economic burden. In this study, we assessed the usefulness of estimating serum neutrophil gelatinase-associated lipocalin (NGAL) as a biomarker in predicting AKI in patients with stable chronic kidney disease (CKD) and undergoing off-pump coronary artery bypass...
