Active clinical trials for "Acute Kidney Injury"

Chronic kidney disease is widespread in the western world with bacterial infection and sepsis as common complication. It has been shown that innate immune defence, represented by dysfunction of neutrophil granulocytes, is impaired in chronic kidney disease. Another impact of chronic kidney disease on innate immunity is the chronic activation of neutrophils leading to high levels of inflammatory cytokines, thus contributing to protein oxidation. Oxidation of human serum albumin (HSA), the major plasma protein, occurs in chronic kidney disease and leads to further activation of neutrophils. Another important impact of HSA oxidation is the decrease of its binding capacity leading to impaired detoxification ability of albumin. This includes reduced clearance of endotoxin, a major component of the gram negative bacterial cell wall. Circulating endotoxin is recognized by complex formation with lipopolysaccharide binding protein (LBP) followed by binding to CD14 and toll-like receptor (TLR) 4. High systemic endotoxin levels occur in chronic kidney disease and may be the result of decreased clearance ability of HSA and increased gut permeability in combination with intestinal bacterial overgrowth. High systemic endotoxin is associated with worse outcome in several diseases and could be used as predictor for mortality in chronic kidney disease patients. Endotoxemia in renal insufficiency leads to impaired neutrophil function and to increased albumin oxidation. Oxidized albumin is not able to bind endotoxin adequately any more, which leads to a further increase in oxidative stress and neutrophil dysfunction, resulting in a vicious cycle. 195 patients with renal dysfunction will be enrolled and divided into 5 groups. Additionally, samples of 25 age and sex-matched healthy controls will be collected. This concept will change the understanding of several aspects of chronic kidney disease and will potentially help to stratify patients into different groups at risk according to their endotoxin status, and their immune and albumin dysfunction. The results of this study will have important implications into the development of novel therapeutic strategies

The purpose of this study is to determine whether Remote Ischemic Perconditioning is effective on Acute kidney injury in adult valve replacement.

Hypothesis: In patients that present to an urban emergency room, a single urine neutrophil gelatinase-associated lipocalin (NGAL) measurement can classify their kidney disease as stable chronic kidney disease, acute tubular necrosis, urinary outlet obstruction or pre-renal azotemia.

The purpose of this study is to demonstrate the efficacy of erythropoietin for prevention acute kidney injury in CKD patients undergoing cardiac surgery.

Some patients who undergo cardiovascular surgery requiring cardiopulmonary bypass will develop a kidney injury following their surgery. The purpose of this study is to take a blood sample from patients before they have this type of surgery and then at nine time points after their surgery to test their plasma for a biomarker called NGAL and compare the NGAL levels to their creatinine levels. We hypothesize that NGAL is an earlier marker for kidney injury than creatinine.

Introduction: Acute kidney injury (AKI) occurs up to 50% of patients admitted to intensive care unit. Plasma Endostatin, released from basement membrane of Bowman's capsule, rises early during AKI. Aim of Work: To investigate the role of the plasma endostatin in the outcome prediction (renal recovery, ICU stay, mortality) of acute kidney injury in patients with sepsis. Methods: a prospective, observational single center study on 40 patients with Sepsis at the Critical Care Department, Cairo University hospitals between March 2019 and November 2019. Serum plasma endostatin was measured at the day of admission & every 48hrs (3 samples). APACHE II, SOFA scores were calculated. Forced diuresis was used if indicated.

This is a monocentre randomized pilot study. All patients received two consecutive RRT: CVVHD with MCO filter (Ultraflux® EMiC®2) and post-Continuous Veno-Venous Hemodiafiltration (CVVHDF) with HFF(AV1000S®) in a controlled randomized (1:1) blinded manner. Crossover randomized to sequence (A+B or B+A) for 48 h total without washout.

Based on animal studies, it was found that administration of endothelial receptor antagonists before and after renal blood vessels clamp and release results in a significantly reduced renal function injury. On the basis of these results, we chose to divide the study population into 2 groups: control group that would be treated the standard accepted preventive treatment: intravenous injection of Mannitol, cooling of the kidney surface, compared to the treatment group that in addition would receive pre- and post-operative treatment of endothelial receptor antagonists (Ambrisentan (Volibris (10mg). To be noticed that the drug is recognized and is given as a primary indication for patients with pulmonary hypertension. The differences between the renal function and biomarkers for pre- and post-operative renal ischemic injury would be examined in order to disclose if the kidney injury of the treated group was indeed smaller. This information will enable us to protect the operated kidneys from the ischemic damage, especially in those patients with poor basic renal function.

The outbreak of Covid-19 started several clinical trials and treatment experiments all over the world in the first months of 2020. This study investigates reports of adverse events related to used molecules, including but not limited to protease inhibitors (lopinavir/ritonavir), chloroquine, azithromycin, remdesivir and interferon beta-1a. Analyses of reports also include the International classification of disease ICD-10 for treatments in the World Health Organization (WHO) global Individual Case Safety Report (ICSR) database (VigiBase).

The aim of this study was to evaluate, in patients with "normal fluid status" assessed by the bio-impedance analysis, whether two different protocol of IV isotonic saline infusion are associated with different volume expansion and differing risks for Contrast Induced Acute Kidney Injury in patients undergoing coronary angiographic procedure.
