Open thoracoabdominal aortic aneurysm (TAAA) repair includes aortic clamping that interrupts antegrade blood flow to distal organs. Ischemia involving the kidneys can lead to renal failure and poor outcomes. To this end, prevention of ischemic kidney damage has led to several perfusion strategies that protect the kidneys during TAAA surgery. Options for renal perfusion include the use of passiv...
BACKGROUND Preservation of renal function is an important objective of renal artery stent procedures. Although atheroembolization can cause renal dysfunction during renal stent procedures, whether adjunctive use of embolic protection devices or glycoprotein IIb/IIIa inhibitors improves renal function is unknown. METHODS AND RESULTS One hundred patients undergoing renal artery stenting at 7 ce...
Erythropoietin (Epo) induces erythrocytosis by suppressing erythroid progenitor cell apoptosis through the Janus-activated kinase-signal transducers and activators of transcription (JAK-STAT) pathway. Since apoptosis contributes to cisplatin (CP)-induced nephrotoxicity and Epo receptors (EpoR) are expressed in the kidney, we examined the role of antiapoptosis in recombinant human erythropoietin...
background: simvastatin is a widely used medication in cardiac care. here we evaluate the role of atp sensitive potassium (katp) channels in simvastatin induced renal protection after renal ischemia/reperfusion (i/r) injury. methods: a total of 81 male wistar rats, were treated with simvastatin (10 and 20mg/kg/day gavage, one week). some groups received glibenclamide (katp channel inhibitor ...
Hypertension, impaired renal function, and proteinuria are commonly associated to the presence of diabetes. They play a major role in the development of cardiovascular and renal damage. Effective antihypertensive treatment reduces the progression of diabetic nephropathy and improves cardiovascular prognosis. Accordingly, tight BP control (<130/80 mmHg) is currently recommended in diabetic patie...
Renal failure from ischemia contributes to morbidity and mortality. Ischemic preconditioning (IP) represents a powerful strategy for kidney protection, and recent advances in transgenic mice may help elucidate its molecular mechanisms. However, murine IP is technically challenging and experimental details significantly influence results. Thus we developed a novel model for renal IP using a hang...
Acute kidney injury (AKI) is one of the most relevant complications after major surgery and is a predictor of mortality. In Western countries, patients at risk of developing AKI are mainly those undergoing cardiovascular surgical procedures. In this category of patients, AKI depends on a multifactorial etiology, including low ejection fraction, use of contrast media, hemodynamic instability, ca...
Renal ischemia-reperfusion injury is a major cause of acute kidney injury. We previously found that renal A(1) adenosine receptor (A(1)AR) activation attenuated multiple cell death pathways including necrosis, apoptosis, and inflammation. Here, we tested whether induction of cytoprotective sphingosine kinase (SK)-1 and sphingosine-1-phosphate (S1P) synthesis might be the mechanism of protection...
Implication for health policy/practice/research/medical education: Metformin protects against tubular injury by modulation of oxidative stress on the tubules and restoring the biochemical alterations. While in diabetes, glycosuria causes tubular cell injury. Furthermore metformin is able to protect podocytes in diabetic nephropathy. These findings may suggest the clinical use of metformin in th...
