Contrast-induced nephropathy (CIN) is a type of acute kidney injury associated with intravascular administration of iodinated contrast, usually reversible. Contrast agents are an essential component of invasive and noninvasive coronary angiography. These agents have been modified over time to enhance patient safety and tolerability, but adverse reactions still occur. CIN has been variably defined, as a rise in serum creatinine of 0.5 mg/dl, or a 25% increase in serum creatinine above baseline within 24-72 hours after the procedure...

Contrast media (CM)-induced nephropathy (CIN) is a serious complication of intravascularly applied radiocontrast media. At present, no drugs have been approved for the prevention of CIN. The present study aimed to explore the effects and potential mechanisms of atorvastatin on iodinated CM-induced cytotoxicity in the human proximal renal tubular epithelial cells. The cytotoxic effect of iohexol (50, 100 and 200 mg I/ml) and the protective effect of atorvastatin pretreatment (1, 20 and 40 µM) were assessed...

Multiple myeloma (MM) is a malignant disorder characterized by clonal proliferation of plasma cells. Renal impairment is a common complication. Contrast-induced nephropathy (CIN) is a form of acute renal failure that can occur in the setting of IV contrast administration. It is more commonly seen in patients with pre-existing renal impairment. Patients with MM commonly require contrast enhanced procedures. The literature regarding the safety of IV contrast in this cohort is lacking. A retrospective review was carried out in a university hospital to identify the incidence of CIN in patients with MM and to look for associated risk factors...

PURPOSE OF REVIEW: This review will address the clinical conundrum of those who may derive clinical benefit from complete revascularization of coronary stenosis that are discovered at the time of ST segment elevation myocardial infarction (STEMI). The decision to revascularize additional vessels with angiographic stenosis beyond the culprit lesion remains controversial, as does the timing of revascularization. RECENT FINDINGS: STEMI patients represent a high-risk patient population that have up to a 50% prevalence of multivessel disease...

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 times a day, 24 hours before the procedure (3 g before PCI) and 2 g after PCI, whereas the control group did not receive L-carnitine...

It is acknowledged that contrast-induced nephropathy (CIN) is a common cause of acute renal insufficiency after cardiac catheterization and affects mortality and morbidity. To date, it is unknown whether oral N-acetylcysteine (NAC) is able to prevent contrast-induced nephropathy (CIN) in patients undergoing coronary angioplasty. A meta-analysis of randomized controlled trials was performed to assess the effects of NAC in the prevention of CIN in patients following coronary angioplasty. A total of 19 studies published prior to January 2015 that investigated the efficacy of oral NAC for the prevention of CIN were collected from Medline, Cochrane and Embase databases and conference proceedings from cardiology and nephrology meetings...

Matrix metalloproteinase-9 (MMP-9) is dysregulated in chronic kidney diseases including diabetic nephropathy. This study was performed to examine the expression of MMP-9 in renal tubule epithelial cells (TECs) under diabetic conditions and its regulatory mechanisms. We characterized MMP-9 protein in diabetic animals and primary cultured rat TECs exposed to exogenous albumin and high glucose. We also used specific inhibitors to determine if internalization of albumin and/or extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation were required for MMP-9 secretion...

Meprins are membrane-bound and secreted metalloproteinases consisting of α and/or β subunits that are highly expressed in kidney epithelial cells and are differentially expressed in podocytes and leukocytes (macrophages and monocytes). Several studies have implicated meprins in the progression of diabetic nephropathy (DN) and fibrosis-associated kidney disease. However, the mechanisms by which meprins modulate DN are not understood. To delineate the role of meprins in DN, we subjected meprin αβ knockout (αβKO) mice and their wild-type (WT) counterparts to streptozotocin-induced type 1 diabetes...

This study aims to determine the safety and efficacy of complete versus staged-percutaneous coronary intervention (PCI) of nonculprit lesions at the time of primary PCI in patients with multivessel disease. Recent trials had suggested that revascularization of nonculprit lesions at the time of primary PCI is associated with better outcomes, however; the optimum timing and overall safety of this approach is not well known. An observational prospective study was conducted, including 50 patients who presented with ST-segment elevation myocardial infarction and found to have at least an additional nonculprit significant (> 70%) type A or B lesion...

Contrast-induced nephropathy (CIN) is a serious complication in patients undergoing percutaneous coronary intervention (PCI), and is associated with higher morbidity and mortality. The limiting volume of contrast medium is safest and most reliable strategy for CIN prevention. Intravascular ultrasound (IVUS) serves as an attractive alternative imaging tool to angiography in many steps during PCI, thereby reducing the use of contrast agents. Here, we reported a case of successfully treated unprotected left main bifurcation lesion with heavily calcified and diffuse lesion under the IVUS-guided PCI using low volumes of contrast dye of total 12 cc in an elderly patient...

Contrast-induced nephropathy (CIN) is a leading cause of hospital-acquired acute kidney injury as a result of iodinated contrast-media use for diagnostic purposes. Pathophysiology remains unclear. In the present study iopromide was administered to New Zealand white rabbits without any prior intervention. Oxidative stress was assessed in blood and tissue level at three anatomical kidney areas (medullary, cortical, juxtamedullary). Histopathological evaluation was also performed. Serum creatinine and urea increased in the CIN groups over 25% at two hours after administration and returned to baseline at 48 h...

BACKGROUND: Several strategies have been envisioned to reduce the risk of contrast-induced nephropathy, but the most modifiable approach for a treating physician is to minimize contrast administration. To date, there is no report on the use of Osprey Medical's new-generation DyeVert Plus system in coronary or peripheral applications. We aimed to appraise the role of the DyeVert Plus system inclusive of contrast reduction and real-time monitoring in a consecutive series of patients undergoing coronary or peripheral invasive procedures...
