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...

Estimates of the incidence of radiocontrast-associated nephropathy vary widely and suffer from misclassification of the cause of AKI and confounding. Using the Nationwide Inpatient Sample, we created multiple estimates of the risk of radiocontrast-associated nephropathy among adult patients hospitalized in the United States in 2009. First, we stratified patients according to the presence or absence of 12 relatively common diagnoses associated with AKI and evaluated the rate of AKI between strata. Next, we created a logistic regression model, controlling for comorbidity and acuity of illness, to estimate the risk of AKI associated with radiocontrast administration within each stratum...

AIM: To compare a fixed-dose intravenous iodinated contrast medium protocol with weight-based dosing protocols for abdominal computed tomography (CT). MATERIALS AND METHODS: Fifty patients were scanned using a fixed-dose protocol, 50 patients were scanned using a full-dose weight-based contrast dosing protocol, and 13 patients were scanned using a reduced dose weight-based protocol. Radiodensity was measured at the portal vein, aorta, spleen, and liver. These values were plotted against contrast medium dose per unit weight...

Contrast media are considered to cause acute kidney injury by activating various factors that induce renal vasoconstriction. We analysed the renal microvascular haemodynamic response using the Doppler flow wire method. Then changes in urinary liver-type fatty acid-binding protein levels following contrast medium administration were compared between groups with or without a micro-injury of the kidney. In the group without renal micro-injury, the average peak velocity (APV) decreased significantly, whereas the renal artery resistance index (RI) increased significantly following contrast medium administration...

Contrast-induced acute kidney injury (CI-AKI) is a common cause of hospital-acquired acute kidney injury (AKI). We evaluated the evidence that uric acid (UA) plays a pathogenic role in CI-AKI. Ten studies were eligible for inclusion for meta-analysis. Hyperuricemia predicted risk for cases with AKI in prospective cohort studies. Higher levels of serum UA (SUA), as defined by the authors, were associated with a 2-fold increased risk to develop AKI (pooled odds ratio 2.03; 95% confidence interval [CI] 1.48-2...

INTRODUCTION: Radiographic contrast administration is a major cause of acute kidney injury (AKI), worldwide. Currently, contrast induced acute kidney injury (CI-AKI) is the third leading cause of hospital acquired renal failure in the United States. Over 50% of these cases are the result of contrast exposure during cardiac catheterization. The predictive risk factors for and clinical impact of AKI following coronary procedures have been extensively studied and documented in the literature...

INTRODUCTION: Despite the patient and medical staff exposure to radiation in endovascular aneurysm repair, the benefits of this abdominal aortic aneurysm type of surgical management are justified by minor recovery time and hospitalization, as well as an option for patients not elected to conventional open repair. In this minimally invasive surgical approach, time of procedure and radiation doses can be substantial--and the increasing frequency of these procedures and it's complexity have impelled vascular surgeons to face additional and successive risk to occupational radiation exposure...

BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) is associated with significantly increased mortality after primary percutaneous coronary intervention (pPCI) for ST-segment elevation myocardial infarction (STEMI). The prognostic value of CI-AKI depends on the definitions used to define it. We compare the predictive accuracy of long-term mortality of two definitions of CI-AKI on consecutive patients undergoing pPCI for STEMI. METHODS: Incidence, risk factors and long-term prognosis of CI-AKI were assessed according to two different definitions: the first as an increase in serum creatinine ≥ 25% or ≥ 0...

Contrast-induced nephropathy after endovascular aortic aneurysm repair (EVAR) in kidney transplant recipients (KTRs) can have devastating consequences. The Vascular Quality Initiative (VQI) database was queried to select all KTRs who underwent EVAR between January 2003 and December 2014. Our primary outcome was renal dysfunction, defined as acute kidney injury (AKI; elevation of serum creatinine >0.5 mg/dL from baseline) or new postoperative hemodialysis requirement. Within the EVAR VQI dataset, 40 patients were KTRs (40 of 17 213, or 0...

BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) is a potential complication in coronary angiography (CAG) and percutaneous coronary interventions (PCI). Prior randomized controlled trials (RCTs) have suggested that statins may play a role in reducing rates of CI-AKI, however it is not clear how firm the current evidence is. OBJECTIVES: The aim of this study was to conduct a meta-analysis and trial sequential analysis to determine the effects of statins in lowering CI-AKI rates in CAG and PCI...

Contrast-induced nephropathy (CIN) is the third leading cause of acute kidney injury in hospitalized patients. The prevalence of CIN is reported to range from 0% to 50%, depending not only on patient condition and the procedure used but also the definition of CIN applied. We aimed to determine the best diagnostic indicator of CIN in patients with normal serum creatinine. This study included 206 patients with normal serum creatinine who underwent coronary angiography/angioplasty. Serum creatinine level and glomerular filtration rate (GFR) were measured before and on the second and fifth days after contrast administration...

Patients with chronic kidney disease (CKD) frequently require radiographic examinations. We investigated the impact of repeated contrast administrations on short- and long-term kidney function and mortality in kidney transplantation candidates. In a prospective study, 81 predialysis transplantation candidates underwent computed tomography angiography (CTA) and invasive coronary angiography (ICA) as part of a pretransplant cardiovascular evaluation. Postcontrast plasma creatinine (P-creatinine) changes were compared with a precontrast control period...

INTRODUCTION: Contrast-induced nephropathy is one of the main causes of acute kidney injury and increased hospital-acquired morbidity and mortality. The use of sodium bicarbonate for nephroprotection has emerged as a preventative strategy; however, its efficacy is controversial compared to other strategies, such as hydration using 0.9% saline solution. OBJECTIVE: To compare the effectiveness of sodium bicarbonate vs. hydration using 0.9% saline solution to prevent contrast-induced acute kidney injury...

Contrast-associated acute kidney injury (CAAKI) is a common iatrogenic condition. The principal risk factors for CAAKI are underlying renal impairment; diabetes in the setting of kidney disease; and intravascular volume depletion, effective or absolute. CAAKI is associated with serious adverse short-term and long-term outcomes, including mortality and more rapidly progressive chronic kidney disease, although the causal nature of these associations remains unproved. Patients with chronic kidney disease and other risk factors for CAAKI who present with acute coronary syndrome should undergo indicated angiographic procedures...
