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...

OBJECTIVES: To investigate the protective effect of different atorvastatin doses on contrast-induced acute kidney injury and the related mechanism. METHODS: Healthy male Sprague-Dawley (SD) rats were randomly divided into the blank control group, experimental control group and different-dose atorvastatin groups. A rat model of contrast-induced acute kidney injury was established. We detected changes in serum creatinine (Scr) and blood urea nitrogen (BUN) before and after model establishment, observed and scored renal tubular injury, analyzed rat renal cell apoptosis, and measure the expression of signal pathway proteins and downstream inflammatory factors...

BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) may led to both a transient and a persistent serum creatinine (sCr) increase. OBJECTIVES: To assess whether serum cystatin C (sCyC) and urine and serum neutrophil gelatinase-associated lipocalin (uNGAL, sNGAL) are useful in the early identification of persistent sCr increase following CI-AKI. METHODS: One hundred and eighteen patients who developed CI-AKI were included into the study...

Several clinical studies have proposed a protective role for vitamin E (α-tocopherol) against contrast-induced acute kidney injury (CIAKI). The aim of study was to assess the effects of vitamin E for the prevention of CIAKI. A systematic review and meta-analysis was conducted using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. Randomized controlled trials (RCTs) reporting the effects of vitamin E on CIAKI development and measurements of renal function were included. Four trials including 623 participants were analyzed in the meta-analysis...

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...

High-dose atorvastatin pretreatment was proved reducing the risk of contrast-induced acute kidney injury (CI-AKI), especially in patients with high C-reactive protein (CRP) levels. We evaluated the effects of common atorvastatin doses (double vs usual) on the risk of CI-AKI and mortality.We recorded outcomes from 1319 patients who were administered periprocedural common doses of atorvastatin. The risks of CI-AKI and mortality between double-dose (40 mg/d) and usual-dose atorvastatin (20 mg/d) were compared using multivariable regression models in all patients or CRP tertile subgroups...

Preexisting renal impairment and the amount of contrast media are the most important risk factors for contrast-induced acute kidney injury (CI-AKI). We aimed to investigate whether the product of contrast medium volume and urinary albumin/creatinine ratio (CMV × UACR) would be a better predictor of CI-AKI in patients undergoing nonemergency coronary interventions. This was a prospective single-center observational study, and 912 consecutive patients who were exposed to contrast media during coronary interventions were investigated prospectively...

Cells lining the proximal tubule (PT) have unique membrane specializations that are required to maintain the high capacity ion transport and endocytic functions of this nephron segment. PT cells in vivo acutely regulate ion transport in response to changes in glomerular filtration rate (GFR) to maintain glomerulotubular balance. PT cells in culture upregulate endocytic capacity in response to acute changes in fluid shear stress (FSS); however it is not known whether GFR modulates PT endocytosis to enable maximally efficient uptake of filtered proteins in vivo Here we show that cells cultured under continuous FSS develop an expanded apical endocytic pathway as well as increased endocytic capacity and lysosomal biogenesis...

Diabetes mellitus is a major risk factor for acute kidney injury (AKI). Here, we hypothesized that suppression of autophagic response underlies aggravation of renal ischemia/reperfusion (I/R) injury by type 2 diabetes mellitus (T2DM). In OLETF, a rat model of T2DM, and its non-diabetic control, LETO, AKI was induced by unilateral nephrectomy and 30-min occlusion and 24-h reperfusion of the renal artery in the contralateral kidney. Levels of serum creatinine and blood urea nitrogen and tubular injury score after I/R were significantly higher in OLETF than in LETO...

BACKGROUND: Guidelines recommend prophylactic hydration for all patients with compromised renal function undergoing contrast exposure. However, the AMACING study published recently showed a noninferior result of hydration compared with no prophylaxis in high-risk patients and led to a heat discussion. This study aimed to validate the effectiveness of prophylactic hydration in different subsets of patients undergoing a contrast procedure. METHODS: We carried out a meta-analysis of randomized-controlled trials to assess pooled estimates of relative risk (RR) and 95% confidence intervals (CIs) for incidences of contrast-induced acute kidney injury (CI-AKI), in-hospital all-cause mortality, and need for dialysis...

Acute kidney injury (AKI) is characterized by tubular cell death and interstitial inflammation. TWEAK promotes experimental kidney injury and activates the transcription factor NF-κB, a key regulator of genes involved in cell survival and inflammatory response. In search of potential therapeutic targets for AKI, we compared a transcriptomics database of NF-κB-related genes from murine AKI-kidneys with a transcriptomics database of TWEAK-stimulated cultured tubular cells. Four out of twenty-four (17%) genes were significantly upregulated (false discovery rate, FDR<0...

OBJECTIVES: Contrast-induced acute kidney injury is a prevalent cause of renal failure, and the noninvasive tools to monitor its progress are lacking. We applied intravoxel incoherent motion (IVIM) DWI to measure the progressive changes in kidney diffusion and perfusion of CI-AKI. METHODS: Twenty-four rats received Iopromide (370 mg/ml, 1600 mg iodine/kg) to induce CI-AKI. IVIM DWI was performed on rats (n = 6) at 24 h prior to and 12, 24, 48, 72, and 96 h after the injection using a 3...

Contrast-induced acute kidney injury (CI-AKI) is associated with increased mortality, morbidity, and prolonged hospitalization. Patients with acute coronary syndrome (ACS) have a 3-fold higher risk of developing CI-AKI. The aim of our study was to evaluate the predictors of CI-AKI and long-term prognosis in patients with ACS who developed CI-AKI (1083 patients were enrolled). Contrast-induced acute kidney injury was defined as an increase of ≥0.5 mg/dL and/or an increase of ≥25% of pre-percutaneous coronary intervention (PCI) to post-PCI serum creatinine levels within 48 to 72 hours after the procedure...

BACKGROUND: Acute kidney injury (AKI) following primary percutaneous coronary intervention (pPCI) is frequently interpreted as contrast-induced AKI but may result from other insults. We aimed to determine the causal association of contrast material exposure and the incidence of AKI following pPCI using a control group of propensity score-matched patients with ST-segment-elevation myocardial infarction who were not exposed to contrast material. METHODS AND RESULTS: We studied 2025 patients with ST-segment-elevation myocardial infarction who underwent pPCI and 1025 patients receiving fibrinolysis or no reperfusion who were not exposed to contrast material during the first 72 hours of hospital stay (control group)...

Contrast-induced nephropathy (CIN) is reversible acute renal failure observed following administration of iodinated contrast media (CM) during angiographic or other medical procedures such as urography. There are various mechanisms through which CM develop their nephrotoxic effects, including oxidative stress and apoptosis. CIN is a real-life, albeit not very rare, entity. Exact pathophysiology remains obscure and no standard diagnostic criteria apply. The Acute Kidney Injury Network criteria was recently employed but its incidence/clinical significance warrants further clarification based on recent methodological advancements, because most published studies to date were contaminated by bias...
