BACKGROUND: Although remote ischemic post-conditioning (RIPC) has been shown to prevent contrast-induced acute kidney injury (CIAKI) in patients with acute coronary syndrome, its efficacy in patients with ST-segment elevation myocardial infarction (STEMI) remains unclear. We examined the relationship among balloon inflations and deflations (BID) times, SYNTAX score of infarction-related artery (SI), periprocedural complications, and CIAKI in STEMI patients undergoing primary percutaneous coronary intervention (pPCI)...

BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) is one of the most common causes of iatrogenic kidney injury and, therefore, its prevention is an important issue. However, whether the administration of 0.9% saline is the optimal prophylaxis method remains uncertain due to its supra-physiologic chloride component. In particular, recent studies suggest that chloride-restricted solutions showed superiority over 0.9% saline in several clinical settings. METHODS/DESIGN: The investigators designed a multicenter randomized controlled trial to compare the efficacy of a balanced salt solution and 0...

BACKGROUND: Renal toxicity induced by cisplatin (CisPt) is a clinical issue in patients with or without chronic kidney disease (CKD). Proximal tubular injury can result in acute kidney injury (AKI), which may compromise the course of chemotherapy and the prognosis. The purpose of this study was to investigate the time course of urinary markers of acute tubulotoxicity and to assess the usefulness of such monitoring in a routine clinical setting. METHODS: This work is an open prospective pilot study carried out among 23 patients receiving a platinum-based chemotherapy...

Destabilized heme proteins release heme, and free heme is toxic. Heme is now recognized as an agonist for the TLR4 receptor. This study examined whether the TLR4 receptor mediates the nephrotoxicity of heme, specifically, the effects of heme on renal blood flow and inflammatory responses. We blocked TLR4 signaling by the specific antagonist TAK-242. Intravenous administration of heme to mice promptly reduced renal blood flow, an effect attenuated by TAK-242. In vitro, TAK-242 reduced heme-elicited activation of NF-κB and its downstream gene MCP-1; in contrast, TAK-242 failed to reduce heme-induced activation of the anti-inflammatory transcription factor, Nrf2, and its downstream gene HO-1...

Contrast-induced acute kidney injury is a phenomenon that has been extensively studied throughout the years. There is a large volume of literature documenting this risk, and most radiology departments and radiologists use this information when making decisions regarding contrast administration. A review of the current information on the topic of contrast-induced acute kidney injury is necessary to ensure that the risks of intravenous contrast are properly weighed against the benefits of a contrast-enhanced computed tomography scan...

Mitochondrial aldehyde dehydrogenase 2 (ALDH2) is closely associated with organ injury. The aim of the present study was to investigate the change of ALDH2 expression in a rat model of sepsis-induced acute renal injury, and to observe the effect of ALDH2 inhibition on the kidney. A model of sepsis syndrome was established in Sprague-Dawley (SD) rats by cecal ligation and puncture (CLP). The rats were divided into sham, CLP and CLP + cyanamide (CYA, an ALDH2 inhibitor) groups. The hemodynamic parameters heart rate (HR) and mean arterial blood pressure (MABP) were measured...

Contrast-induced acute kidney injury (CI-AKI) is the acute impairment of renal function further to the intravascular administration of iodinated contrast media, and occurs most frequently after coronary angiography, percutaneous coronary intervention, and contrast-enhanced computed tomography. CI-AKI has been associated with the development of acute renal failure, worsening of chronic kidney disease, requirement for dialysis, prolonged hospital stay, and higher mortality rates and health care costs. Recently, a number of studies suggested that contrast media exposure might not be the causative agent in the occurrence of acute kidney injury, particularly in stable patients who receive small to moderate amounts of contrast media...

OBJECTIVES: To assess, whether cardiac catheterization via radial access prevents contrast-induced nephropathy. BACKGROUND: Contrast-induced nephropathy (CIN) is a major clinical problem which accounts for more than 10% of acute kidney injury cases in hospitalized patients. Protective measures such as the infusion of isotonic saline solution or acetylcysteine have not consistently been proven to prevent acute kidney injury (AKI). However, there is growing evidence that radial access for coronary angiography and coronary intervention is associated with a lower incidence of AKI compared to femoral access...

In this study, we tested the hypothesis that fasudil, a Rho kinase inhibitor, would protect against contrast-induced acute kidney injury (CI-AKI) in a mouse model and attempted to elucidate the mechanism involved. Mice subjected to unilateral ligation of the left anterior renal pedicle were divided into four groups: (1) control group, (2) CI-AKI induced by contrast media (CM group), (3) CI-AKI plus low-dose fasudil (LD group) and (4) CI-AKI plus high-dose fasudil (HD group). Animals from groups 2-4 received iodixanol (4...

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...

Inflammation plays a crucial role in acute kidney injury (AKI). The current study was designed to analyze the influence of prednisolone treatment on the inflammatory reaction during the first 96 h after AKI induction in a rat model. AKI was induced by unilateral clipping of the renal vessels. The treatment group received prednisolone 5 mg/kg s.c. daily. Infiltration rates of macrophages, leukocytes, and T-cells (24, 96 h) as well as plasma concentrations of the inflammatory markers intercellular adhesion molecule, interleukin-1 beta (IL-1β), IL-18, IL-6, and tumor necrosis factor-alpha (0, 6, 24, 96 h) were determined by fluorescence-activated cell sorting (FACS) analysis only...

Contrast medium (CM) is widely used in cardiac catheterization; however, it may induce acute kidney injury or renal failure, although the underlying mechanism remains to be elucidated. MicroRNA‑21 (miR‑21) is involved in renal disease and has been indicated to regulate cellular apoptosis and fibrosis, although its role in CM‑induced renal cell injury is unknown. The present study examined the expression and potential targets of miR‑21 in human renal proximal tubular epithelial (HK‑2) cells following CM treatment...

BACKGROUND New renal biomarkers such as neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) show promise in early diagnosis of contrast media induced acute kidney injury (CI-AKI). The purpose of our study was to compare the subclinical nephrotoxicity (a condition without changes in standard renal biomarkers) of gadolinium-based contrast media (Gd-DTPA, gadopentetate dimeglumine) and iodinated-based contrast media (iopromide) in pediatric patients with normal kidney function...

BACKGROUND: Contrast-induced acute kidney injury (CIAKI) is a common cause of hospital-acquired acute kidney injury (AKI). S100A8/A9-TLR4-NLRP3 inflammasome pathway triggers inflammation, apoptosis and tissue injury in several AKI models. Nevertheless, the underlying mechanism of S100A8/A9-TLR4-NLRP3 inflammasome pathway in CIKAI is not clear. We aimed to investigate the possible role of S100A8/A9-TLR4-NLRP3 inflammasome in the pathophysiology of CIAKI. METHODS: We treated male rats and NRK-52E cells by iopromide to establish in vivo and in vitro models of CIAKI...

Renal Artery Stenosis (RAS) is an important cause of treatment-resistant hypertension. Uncontrolled hypertension with RAS can cause progressive chronic kidney disease (CKD) leading to end-stage kidney disease. Therapeutic revascularisation can be helpful in appropriate circumstances where pharmaceutical intervention has failed and significant renovascular disease contributes to resistant hypertension. We present an interesting case of a Caucasian male with peripheral vasculopathy, abdominal aortic aneurysm (AAA), single functioning kidney and ostial RAS caused by stent struts from an endovascular AAA stent graft...
