AIMS: We aimed to compare the diagnostic efficacy of serum cystatin C (sCyC) for contrast induced nephropathy (CIN) in Western Indians undergoing cardiac catheterization. We also aimed to propose a clinically applicable cut-off of sCyC for early identification of CIN in this ethnic group. METHODS: In this prospective study, 253 patients undergoing coronary angiography and/or percutaneous coronary intervention were enrolled. The demographic and risk factor details, levels of sCr at baseline, 24 and 48h after the procedure, whereas baseline and 24h levels of sCyC were noted...

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)...

Diabetic nephropathy (DN) is one of the most common and lethal microvascular complications of diabetes. This study aimed to explore whether coenzymeQ10 (CoQ10) as an antioxidant combined with ultrasound-targeted microbubble destruction (UTMD) could reverse the progress of early diabetic nephropathy (DN). CoQ10 has great potential to treat early DN. However, the clinical application of CoQ10 has been limited because of its low aqueous solubility and non-specific distribution. Therefore, CoQ10-loaded liposomes (CoQ10-lip) were prepared and combined with ultrasound microbubbles for the early theranostics of DN...

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...

BACKGROUND: Contrast-induced nephropathy (CIN) is a major drawback in percutaneous coronary intervention (PCI). Significant uricosuria has been reported following contrast exposure. Allopurinol-a xanthine oxidase inhibitor-has been suggested to prevent the formation of oxygen-free radicals, which may contribute to CIN. The aim of the present study was to evaluate the possible efficacy of allopurinol in preventing CIN. METHODS: In this double-blind placebo-controlled trial, patients with an estimated glomerular filtration rate ≥60 mL/min who were admitted for elective PCI, were randomized to receive either allopurinol 600 mg or a placebo administered 24 h before the procedure, and again immediately before the procedure...

OBJECTIVE: This study aimed to test the association of both the baseline values and post-procedural variations of urinary and serum Neutrophil Gelatinase-Associated Lipocalin (NGAL) and Cystatin C (CysC) with contrast induced nephropathy (CIN) occurrence in patients undergoing percutaneous coronary invasive procedures (PCIP), and compare them to serum creatinine and the estimated glomerular filtration rate (eGFR). METHODS: In 43 patients admitted to our Cardiac Step-Down Unit and submitted to PCIP, we measured serum creatinine and eGFR as the standard markers for CIN diagnosis, and compared them to both serum and urinary NGAL as well as serum CysC, assessed before and 4 hours after PCIP...

BACKGROUND: Contrast-induced nephropathy (CIN) in native kidneys is associated with a significant increase in mortality and morbidity. Data regarding CIN in renal allografts are limited, however. We retrospectively studied CIN in renal allografts at our institution: its incidence, risk factors, and effect on long-term outcomes including allograft loss and death. METHODS: One hundred thirty-five renal transplant recipients undergoing 161 contrast-enhanced computed tomography (CT) scans or coronary angiograms (Cath) between years 2000 and 2014 were identified...

Diabetic nephropathy (DN) is among the most severe complications of diabetes mellitus, and may lead to end-stage renal disease. Sustained exposure to advanced glycation end products (AGEs) typically causes renal tubular epithelial cells (TECs) to suffer from an epithelial-to-mesenchymal transition (EMT). However, there remains no consensus regarding the mechanism underlying the cause of EMT in TECs as induced by AGEs. In the present study, we investigated the promotion of EMT in TECs by AGEs, and the activation of Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling...

BACKGROUND AND PURPOSE: Because of the perceived risk of contrast-induced acute kidney injury (AKI), many centers require pre-imaging serum creatinine levels, potentially delaying care. We performed a systematic review and meta-analysis evaluating AKI rates in patients with acute ischemic stroke receiving computed tomographic angiography (CTA) and computed tomographic perfusion (CTP). METHODS: We searched MEDLINE, EMBASE, and the Web of Science through December 2016 for studies reporting on AKI in patients with acute ischemic stroke receiving CTA/CTP...

Contrast-induced nephropathy (CIN) is an important complication following diagnostic radiographic imaging and interventional therapy. It results from administration of intravascular iodinated contrast media (CM) and is currently the third most common cause of hospital-acquired acute kidney injury. CIN is associated with increased morbidity, prolonged hospitalization and higher mortality. Although the importance of CIN is widely appreciated, and its occurrence can be mitigated by the use of pre- and post-hydration protocols and low osmolar instead of high osmolar iodine-containing CM, specific prophylactic therapy is lacking...

BACKGROUND: Contrast induced nephropathy (CIN) may be defined as Acute Renal Failure (ARF) that occurs within 24-72h of exposure to intra-venous or intra-arterial iodinated contrast media that cannot be attributed to other causes. CIN occurs in up to 5% of hospitalized patients with normal renal function prior to injection of contrast media. It occurs more frequently in patients with renal impairment particularly if associated with diabetic nephropathy. Among all procedures utilizing contrast agents for either diagnostic or therapeutic purposes, coronary angiography and percutaneous coronary interventions are associated with the highest rates of CIN...

Clinical guidelines recommend prophylactic hydration to reduce the risk of contrast-induced nephropathy in high-risk patients, including those with chronic kidney disease. A recent single-center randomized trial showed no significant difference in the incidence of contrast-induced nephropathy in ambulatory patients with stage 3 chronic kidney disease who were randomized to no prophylactic hydration versus normal saline hydration. While these results may identify patients who are less likely to benefit from prophylactic hydration, nephrologists and interventionalists should carefully consider the generalizability of these results to individual patients...
