Chronic kidney disease (CKD) is a significant risk factor for contrast induced acute kidney injury (CI-AKI) after percutaneous coronary intervention (PCI). This study included 1592 CKD patients extracted from a prospective multicenter, all comer-based registry of patients undergoing PCI. In multivariate logistic analysis for CI-AKI development, a significant linear trend was observed between the quartiles of HDL-C (quartile 1 vs. 2: odds ratio [OR], 0.716; 95% confidence interval [CI], 0.421-1.219; quartile 1 vs...

BACKGROUND AND AIMS: Decreased nitric oxide (NO) bioavailability and increased oxidative stress may be involved in the pathogenesis of contrast-induced acute kidney injury (CI-AKI). The relationship between asymmetric dimethylarginine (ADMA), an endogenous NO synthase inhibitor, and CI-AKI is unknown. METHODS: We measured plasma ADMA levels in 664 consecutive subjects undergoing cardiac catheterization. Mehran score for predicting the risk of CI-AKI was calculated...

OBJECTIVE: Remote ischemic preconditioning (RIPC) induces transient episodes of ischemia by the occlusion of blood flow in non-target tissue, before a subsequent ischemia-reperfusion injury. When RIPC is applied before percutaneous coronary intervention (PCI), the kidneys may be protected against ischemia-reperfusion injury and subsequently contrast-induced acute kidney injury (CI-AKI). The aim of this study was to evaluate the efficacy of RIPC for the prevention of CI-AKI in patients with diabetes with pre-existing chronic kidney disease (CKD) undergoing elective PCI...

Iodinated contrast media serves as a direct causative factor of acute kidney injury (AKI) and is involved in the progression of cellular dysfunction and apoptosis. Emerging evidence indicates that NLRP3 inflammasome triggers inflammation, apoptosis and tissue injury during AKI. Nevertheless, the underlying renoprotection mechanism of NLRP3 inflammasome against contrast-induced AKI (CI-AKI) was still uncertain. This study investigated the role of NLRP3 inflammasome in CI-AKI both in vitro and in vivo. In HK-2 cells and unilateral nephrectomy model, NLRP3 and NLRP3 inflammasome member ASC were significantly augmented with the treatment of contrast media...

Contrast-induced acute kidney injury (CI-AKI) is a problem associated with the use of iodinated contrast media, causing kidney dysfunction in patients with preexisting renal failure. It accounts for 12% of all hospital-acquired kidney failure and increases the length of hospitalization, a situation that is worsening with increasing numbers of patients with comorbidities, including those requiring cardiovascular interventional procedures. So far, its diagnosis has relied upon the rise in creatinine levels, which is a late marker of kidney damage and is believed to be inadequate...

BACKGROUND: Hyperuricemia may be associated with an increased risk of contrast-induced acute kidney injury (CI-AKI). In recent years, studies about the relationship between them gradually appeared. We performed a systematic review and meta-analysis to investigate whether hyperuricemia is an independent risk factor for CI-AKI. METHODS: Relevant studies were searched in PubMed, Embase, Cochrane Library, and CBM (Chinese Biomedical Literature database) databases until April 18, 2016, without language restriction...

Contrast medium administration is one of the leading causes of acute kidney injury (AKI) in different clinical settings. The aim of the study was to investigate occurrence and predisposing factors of AKI in cirrhotic patients undergoing contrast-enhanced computed tomography (CECT).Datasets of 1279 consecutively hospitalized cirrhotic patients were retrospectively analyzed. Two hundred forty-nine of 1279 patients (mean age 64 ± 11 years, 165 male) who had undergone CECT were selected on the basis of the availability of serum creatinine (sCr) values evaluated before and after CECT (CECT group)...

Coronary angiography and percutaneous intervention rely on the use of iodinated intravascular contrast for vessel and chamber imaging. Despite advancements in imaging and interventional techniques, iodinated contrast continues to pose a risk of contrast-induced acute kidney injury (CI-AKI) for a subgroup of patients at risk for this complication. There has been a consistent and graded signal of risk for associated outcomes including need for renal replacement therapy, rehospitalization, and death, according to the incidence and severity of CI-AKI...

Carotid artery stenting (CAS) is increasingly offered to patients with carotid artery stenosis. Although CAS is a less invasive (and thus more attractive) alternative compared with carotid endarterectomy, it requires the use of contrast material. A possible side effect from the use of contrast material during CAS is the development of contrast-induced acute kidney injury (CI-AKI). This review discusses the incidence/prevalence and clinical significance of CI-AKI developing after CAS. We also discuss possible measures to reduce the incidence of CI-AKI after CAS...

Hypoxia, reactive oxygen species (ROS) and oxidative stress contribute to contrast-induced acute kidney injury (CI-AKI) and ischemic reperfusion injury (IRI) in the kidney and heart. Imbalance between the increased formation of ROS by hypoxia in the cardiac and renal tissue and the low availability of endogenous antioxidants is a common cause of cellular and tissue damage. Therefore, a strategy to inhibit ROS generation or to scavenger free radicals becomes an important intervention to prevent CI-AKI and myocardial IRI...

Acute kidney injury (AKI) is an increasingly common and feared complication in hospitalized patients. The selection of appropriate primary and secondary end points is critical to the design and eventual success of clinical trials aimed at preventing and treating AKI. In this article, we provide an overview of AKI definitions and suggestions on the rational selection of end points for clinical trials in various settings, including the prevention of contrast-induced AKI, prevention of cardiac surgery-associated AKI, treatment of established AKI, and treatment of dialysis-requiring AKI...

BACKGROUND: Recent studies and meta-analysis have shown that complete revascularization (CR) compared with infarct-related artery revascularization (IRA) during percutaneous coronary intervention for ST-segment elevation myocardial infarction (STEMI) is associated with decreased mortality. However, it is unclear if CR versus IRA in STEMI during indexed hospitalization is associated with risk of contrast-induced acute kidney injury (CI-AKI). METHODS: A database search was conducted for all randomized controlled trials that enrolled STEMI patients and compared CR versus IRA and reported CI-AKI...

BACKGROUND: Patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) are at an increased risk of developing contrast-induced acute kidney injury (CI-AKI). Data on the association between transradial (TRA) vs. transfemoral (TFA) access and the risk of CI-AKI in this setting are limited. METHODS: We analyzed data on 1162 patients undergoing primary PCI for STEMI at two tertiary care centers between 2010 and 2014...

Dieting often leads to body weight cycling involving repeated weight loss and regain. However, little information is available regarding rapid-response serum markers of overnutrition that predict body weight alterations during weight cycling. Here, we report the rapid response of serum leukocyte cell-derived chemotaxin 2 (LECT2), a hepatokine that induces insulin resistance in skeletal muscle, during diet-induced weight cycling in mice. A switch from a high-fat diet (HFD) to a regular diet (RD) in obese mice gradually decreased body weight but rapidly decreased serum LECT2 levels within 10 days...

The relative contribution of self-perpetuating versus hemodynamic-induced fibrosis to the progression of chronic kidney disease (CKD) after acute kidney injury (AKI) is unclear. In the present study, male Sprague-Dawley rats underwent right uninephrectomy and were instrumented with a blood pressure radiotelemeter. Two weeks later, separate groups of rats were subjected to 40 minutes renal ischemia-reperfusion or sham surgery and followed up for 4 or 16 weeks to determine the extent to which glomerulosclerosis and tubulointerstitial fibrosis as a result of the AKI-CKD transition (ie, at 4 weeks post AKI) change over time during the progression of CKD (ie, at 16 weeks post AKI)...

Contrast-induced acute kidney injury (CI-AKI) is a common complication of intravascular administration of contrast media used in coronary angiography, percutaneous coronary intervention and other diagnostic and interventional procedures. This review article aims at summarizing the published literature regarding the prevention of CI-AKI, by focusing on available high-quality meta-analyses addressing this matter. Apart from adequate hydration, a number of pharmacologic agents have been proposed as potential candidates to be included in the routine preparation, prior to the patient's arrival in the cardiac catheterization laboratory...

BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) is typically defined by an increase in serum creatinine after intravascular administration of contrast medium. Because creatinine is an unreliable indicator of acute changes in kidney function, we assessed whether circulating microRNAs (miRNAs) could serve as biomarkers for early detection of CI-AKI. METHODS AND RESULTS: Using a rat model of CI-AKI, we first evaluated the miRNA profile of rat plasma and kidney...
