Active clinical trials for "Acute Kidney Injury"

Acute renal injury (AKI) is a common complication after cardiac surgery and is associated with worse outcomes. It is now realized that intraoperative hypotension is an important risk factor for the development of AKI. In a recent randomized controlled trial of patients undergoing major noncardiac surgery, intraoperative individualized blood-pressure management reduced the incidence of postoperative organ dysfunction. The investigators hypothesize that, for patients undergoing off-pump CABG, targeted blood-pressure management during surgery may also reduce the incidence of postoperative AKI.

This is a multicenter, randomized, open-label phase II clinical trial to evaluate alprostadil liposomal injection in the prevention of contrast-induced acute kidney injury in patients undergoing percutaneous coronary intervention.

The protective nitric oxide (NO) effects are mediated by selective pulmonary vasodilation and improvement of arterial oxygenation in hypoxemic patients by reducing intrapulmonary shunting and improving ventilation-perfusion coordination. Inhaled NO has been used for years to treat acute respiratory failure and pulmonary hypertension in anesthesia and intensive care. The nephroprotective role of NO was studied in an experimental model of contrast-induced nephropathy. The primary aim of this prospective, double-blind, randomized, parallel-group, controlled trial is to test the hypothesis that perioperative conditioning of patients with NO at a dose of 80 ppm, obtained by plasma-chemical synthesis technology, through a ventilator and an extracorporeal circulation circuit reduces the incidence of acute kidney injury (AKI) in patients with an initially high risk of kidney damage due to the presence of preoperative chronic kidney disease (CKD). The study is interventional. Examination and treatment of patients is carried out in accordance with the approved standards of medical care for the relevant diseases. During the study, no experimental or unregistered (not approved for use) medical or diagnostic procedures in the territory of the Russian Federation will be carried out. The study includes patients admitted to the Cardiac Surgery Department of Cardiology Research Institute of Tomsk NRMC for elective surgery with high risk of AKI in the perioperative period

Justification: Studies in recent years have shown that suffering an episode of acute kidney injury (AKI) is an independent risk factor for developing chronic kidney disease (CKD), which is associated with cardiovascular complications, increases medical care costs, and decreases survival. These AKI to ERC transition cases add to the growing number of CKD cases already being seen globally. It is for them that in recent years therapeutic strategies have been sought to reduce or stop this process of transition from AKI to CKD. Objective: To evaluate the efficacy and safety of the use of dapagliflozin plus standard medical treatment (TMS), compared with only TMS for 21 days, in hospitalized patients with a diagnosis of severe AKI (KDIGO 3) in reducing the incidence of CKD to 18 months of follow-up. Design: Randomized, single center, open study. 100 hospitalized patients with a diagnosis of AKI KDIGO 3, without previous CKD, will be randomized to receive 10 mg of dapagliflozin every 24 h for 21 days + TMS or only TMS. During their follow-up, baseline blood and urine samples will be taken and at 3, 6, 12 and 18 months. At 18 months, the development of CKD will be assessed using the KDIGO clinical criteria and with the determination of urinary biomarkers (Serpina A3, HSP72, KIM 1 and NGAL).

Acute kidney injury (AKI) is common in intensive care unit (ICU) and inducing a high morbidity and mortality. In severe forms of AKI (more than 25% of AKI patients admitted to the ICU), renal replacement therapy (RRT) is often necessary. Although RRT is a cornerstone of therapy, it can lead to serious adverse effects, such as intradialytic arterial hypotension. Indeed, arterial hypotension during the session - intra-dialytic arterial hypotension (IDH) - occurs frequently complication and so regardless of the RRT modality used. Its occurrence may worsen significantly the outcome as previously reported. It is therefore of parmount importance to prevent such an adverse effect. The investigators hypothesize that a decrease in the central venous oxygen saturation (SvcO2) measured related to a decreased cardiac output could precede the onset of IDH. The aim of this study is collect IDH in AKI patients and to measure continuously SvcO2 during RRT session in order to investigate its role in predicting IDH.

Multi-centre, triple-blinded (patients, physicians, investigators), parallel-group, balanced (1:1), stratified (male-female 50-50), randomized, controlled (placebo), phase IV clinical trial to investigate the potential of preoperative initiation (from day 1 before surgery) and perioperative continuation (until day 2 after surgery) of the SGLT2 inhibitor dapagliflozin 10 mg once daily to prevent AKI according to the KDIGO criteria (an increase in serum creatinine by 0.3 mg/dl (26.5 mmol/l) within 48 hours; or an increase in serum creatinine to 1.5 times baseline, within 7 days; or a urine output <0.5 ml/kg/h for >6 hours) in adult (>18 years old) patients undergoing cardiopulmonary bypass surgery.

The use of contrast media (CM) poses a risk of post-contrast acute kidney injury (PC-AKI), especially among patients chronic kidney disease (CKD). International guidelines recommend intravenous (IV) hydration with isotonic 0.9% NaCl for three-four hours pre-contrast and four-six hours post-contrast. Recent studies have proven that oral hydration or no hydration is non-inferior to IV hydration in patients with mild to moderate CKD (eGFR 30-60 mL/min/1.73 m2). However, no randomized controlled trials have evaluated alternative hydration methods against the guideline-recommended hydration protocol for the prevention of PC-AKI in high-risk patients with severe CKD (eGFR < 30 mL/min/1.73 m2). Thus, the main focus of this trial is to evaluate IV hydration vs. oral hydration for their efficacy to prevent of PC-AKI in patients with severe CKD, who are scheduled for an elective contrast-enhanced CT-scan (CECT) with IV contrast-administration. Our research hypotheses consist of the following: Oral hydration with bottled tap water is non-inferior to IV-hydration with isotonic 0.9% NaCl as renal prophylaxis to prevent PC-AKI in patients with severe CKD referred for an elective IV CECT. NGAL and cfDNA are early and precise plasma and urinary biomarkers of PC-AKI with excellent diagnostic and prognostic accuracy for PC-AKI, dialysis, renal adverse events, hospitalization, progression in CKD-symptoms, and all-cause mortality.

The development of acute kidney injury (AKI) during septic shock is frequent and is associated with a high mortality rate. The reason of this increased mortality despite the use of renal replacement therapy is still unknown. The deleterious effects of uremic toxins (solutes accumulating with the loss of kidney function) has risen for the last decade in chronic kidney disease patients. Among those solutes, indoxyl sulfate (IS) is associated with the development of cardiovascular complications and impairment of immune response. The role of uremic toxins and particularly IS in the prognostic of septic kidney injury is unknown. The investigators propose to analyze the relation between the serum concentration of IS and the mortality of patients hospitalized for a septic shock who developed an AKI.

The use of imaging is increasing in clinical practice, either for diagnosis or intervention. In these imaging processes, contrast medium (CM) is widely used. However, CM administration can induce contrast-induced nephropathy (CI-AKI). CI-AKI is the third most common cause of renal insufficiency, and its incidence varies from 2% to 50% depending on patient risk factors; in addition, studies have shown that CI-AKI occurs in 2% to 25% of patients undergoing coronary intervention. CI-AKI is associated with significant mortality and morbidity in patients undergoing coronary angiography or other diagnostic contrast studies. We assessed the latest promising evidence on the ability of remote ischemic preconditioning (RIPC) to reduce the incidence of CI-AKI in patients undergoing Coronary Angiogram (CA) or diagnostic contrast studies such as CT angiogram, while at the same time being a non-invasive, low cost, easy, and safe method with absence of adverse effects. However, more randomized controlled trials are needed to confirm these preliminary results. The aim of this study is to minimize the incidence of CI-AKI at the University of Texas Medical Branch (UTMB). If found to be an effective method, RIPC would help minimize the incidence of CI-AKI in all institutions across the globe, who would adopt this intervention. The primary objective: i) reduce the rise in creatinine to < 0.5 mg/dL post-CA in moderate to high risk patients and ii) reduce the incidence of renal replacement therapy post-CA in moderate to high risk patients; iii) we also aim to establish that RIPC is safe and effective. We hypothesize that the use of RIPC, when added to standard medical therapy (pre-and post-CA hydration), will mitigate the effects of contrast on the renal vasculature and lessen the incidence of CI-AKI in moderate to high risk patients at the University of Texas Medical Branch. The use of iodinated contrast to visually enhance target vasculature is a widely used diagnostic technique that is performed daily at UTMB, and around the world, for the diagnosis and management of a variety of conditions. A common complication of this procedure is acute kidney injury (AKI), generally referred to as contrast-induced nephropathy (CI-AKI). This complication can range from an isolated rise in serum creatinine to severe renal dysfunction necessitating renal replacement therapy. The incidence of CI-AKI has been reported as approximately 2-50%, depending upon the definition and sensitivity of assay employed to assess GFR in the hospital setting. In addition, CI-AKI is associated with significant mortality and morbidity. If proven to be beneficial, RIPC will bring about a reduction in incidence of CI-AKI, and thus help to reduce hospitalization and mortality from renal etiology following a given contrast procedure.

This study is a single-center, prospective, randomized, double-blinded, placebo-controlled phase II clinical trial to evaluate the efficacy of "NAD+ supplementation" with Basis™ (Nicotinamide Riboside and Pterostilbene) in preventing acute kidney injury (AKI) in patients undergoing complex aortic aneurysm repair and open aortic arch reconstruction.
