Active clinical trials for "Acute Kidney Injury"

A study to evaluate the prevalence of Acute Kidney Injury (AKI) in patients with Diabetic Ketoacidosis (DKA) and sepsis using data collected prospectively to a patient registry. The primary objective is to compare the prevalence of AKI in sepsis and DKA in different age groups in children and investigate the difference in the prevalence of hyperchloremia in the two groups.Secondary objectives are Compare the prevalence of AKI in sepsis and DKA in different age groups in children and investigate the difference in the prevalence of hyperchloremia in the two groups.

We aimed to investigate the effect of Acute Kidney Injury (AKİ) on the prognosis of patients hospitalised for COVID-19.

Coenzyme Q10 (CoQ10) is an essential molecule in human body. It acts as an antioxidant, a co-factor for energy conversion in mitochondria and has anti-inflammatory effects capable of improving endothelial function. Our goal is to investigate whether CoQ10 is capable to reduce the incidence of acute kidney injury/failure following cardiac surgery. Cardiac surgery is major risk factor for acute kidney injury/failure (AKI/F).

Patients with severe infection and sepsis are in high risk of hypo perfusion and therefore organ affection. Temporary or permanent kidney failure is a common complication in these patients. Today's golden standard for kidney failure detection is creatinine levels rising and / or oliguria. The investigators hypothesize that an even more sensitive biomarker; neutrophil gelatinase associated lipocalin(NGAL) in urine can predict kidney injury before creatinine levels rise. In recent studies NGAL in urine seem to be a sensitive biomarker in these patient to predict kidney injury, but the time factor for sampling optimally is not known. In this pilot study the investigators sample the urine at admission within the first hour of hospitalization to investigate if NGAL can be used as a predictor in an emergency setting.

This study aims to assess if applying an ischaemic insult to an arm before giving intravenous contrast will help decrease the incidence of developing contrast induced acute renal injury in patients undergoing contrast-enhanced CT Scans. The main research question is 'In adult in-patients undergoing contrast-enhanced CT scans, does remote ischaemic pre-conditioning (RIPC) induced by brief arm ischaemia and reperfusion, when compared to control, reduce the proportion of patients developing contrast-induced acute kidney injury in the first 3 post-scan days? '.

Acute kidney injury (AKI) occurs in 40% of children following heart surgery. Serum creatinine (Scr) is a late biomarker of AKI, rising 24-48 hours after surgery. Thus, for medicines excreted in the urine, AKI could potentially lead to toxic levels in the blood. Urinary biomarkers have the ability to detect AKI earlier. Whether early detection of AKI through urinary biomarkers can predict altered drug levels is unknown. Milrinone is used to improve heart function after surgery, but accumulates in AKI resulting in low blood pressure. Dose adjustments are not currently possible because of the late rise in SCr, and are based on clinical parameters that may lead to clinically relevant over or under-dosing. Thus, this study will address an important knowledge gap being the first to use elevations of AKI biomarker concentrations to anticipate increased milrinone levels.

This research project consists of a prospective diagnostic study conducted on patients with clinical suspicion of rhabdomyolysis admitted to the emergency rooms of the University Hospitals of Nimes, Montpellier, Paris, Nice and Toulon Inter Army Hospital. The main objective of this study is to determine whether the plasma level of Neutrophil Gelatinase Associated Lipocalin (NGAL) may be retained as a predictor of acute renal failure (ARF) occurring within 48 hours after admission for rhabdomyolysis.

Compared to chronic dialysis, kidney transplantation provides recipients with longer survival and better quality of life at a lower cost. In order to meet increasing demands for kidney allografts, kidneys from older and sicker donors are being procured. This has led to greater discard rates of donated kidneys as well as more complications for recipients, including shorter allograft survival. Available clinical models to predict kidney allograft quality have poor prognostic ability and do not asses the degree of kidney allograft injury. However, allograft injury near the time of procurement can lead to major consequences for the transplant recipient: greater risks of delayed graft function, poor allograft function and premature loss of the transplant. Our proposal is based on the hypotheses that novel biomarkers measured in donor urine and transport media at the time of procurement can assess acute and chronic kidney injury and that distinct biomarker patterns will predict allograft survival. In collaboration with five organ procurement organizations, we will collect urine samples from consecutive deceased donors and samples of transport solution for every pumped kidney. We will measure markers of injury, repair, inflammation and fibrosis. We will determine mortality and allograft survival in all patients by linkage to the United Network for Organ Sharing (UNOS) database (Overall Cohort). Additionally, we will perform a detailed chart review of a subset of recipients (detailed cohort) and will also examine associations between biomarkers and longitudinal graft function over five years after transplant. Early, non-invasive and rapid assessment of donor kidney injury could drive better allocation decisions and potentially reduce the rates of post-transplant complications. Further, these new tools could provide a platform for clinical trials of therapies for allografts and kidney transplant recipients aimed at ameliorating allograft injury.

Contrast-induced nephropathy (CIN) represents a potential complication of diagnostic and therapeutic procedures in interventional cardiology, especially in the acute setting of primary PCI. The investigators will test the efficacy of sodium bicarbonate (NaHCO3) and N-acetylcysteine (NAC) on the prevention of acute events and CIN in patients with acute myocardial infarction.

People who undergo coronary artery bypass grafting (CABG) or heart valve surgery may experience acute kidney injury (AKI) after their surgery. Current medical tests cannot identify AKI until approximately 48 hours after it occurs. This study will examine three new biomarkers in blood and urine that may provide a more effective and faster way of predicting AKI in people who undergo CABG or heart valve surgery.
