Active clinical trials for "Acute Kidney Injury"

This a prospective, double-blind, sham-controlled, randomized clinical trial to study the effects of remote ischemic preconditioning on contrast-induced acute kidney injury, vascular and renal biomarkers in patients with non-ST elevation myocardial infarction and unstable angina undergoing cardiac catheterization and percutaneous coronary intervention.

This purpose of this pilot and feasibility study is to determine whether attending an acute kidney injury (AKI) clinic after discharge from the hospital impacts prescription medicine use, blood pressure and recovery of kidney function as compared to usual care.

Kidney injury is a common complication following liver transplantation and is associated with a higher complication rate and increased risk of death. While there are many factors that likely contribute to kidney injury in the perioperative period, a relative low serum level of angiotensin 2 (Ang 2) (a protein hormone that causes blood vessels to narrow) found in patients with liver cirrhosis (late stage of liver damage) may increase their risk of developing acute kidney injury (sudden episode of kidney failure or damage). We propose to investigate how early administration of Ang 2, a new vasopressor drug approved by the FDA in December 2017 for patients with low blood pressure, during the intra-operative period of liver transplant surgery affects the rate of kidney injury after transplantation. Patients who are deemed appropriate candidates for the study will be randomized 1:1 to the treatment and control groups. The intervention period of the study will occur in the operating room during transplant surgery and will be performed by their anesthesiologists. In the Treatment group, patients will receive Ang 2 infusions in addition to other standard vasopressors while patients in the control group will receive standard vasopressors alone. The infusion of Ang 2 in the treatment group will continue through the duration of the surgery and will be stopped prior to leaving the operating room. Both the treatment group and the control group will then be followed for 14 days to evaluate rates of kidney injury and to look for any complications. The follow up period will be extended to 28 days to look at in-hospital mortality rates in both groups. The daily follow up analysis will occur while the enrolled patients are inpatient following their transplantation surgery and will be done by looking at lab values and other data that is routinely gathered by their managing teams. This study will serve as a pilot study to evaluate feasibility of our protocol and to collect some preliminary data on the use of Ang 2 in this patient population. As such we plan to enroll approximately 30 patients who have accepted an offer to receive a donor liver. We hope to reach our goal enrollment within 5 months of starting the study.

Ultomiris (Ravulizumab), is a monoclonal antibody that specifically targets terminal complement products and is proposed for the treatment of COVID-19 induced microvasculature injury and endothelial damage leading to thrombotic microangiopathy (TMA) causing acute kidney injury (AKI). Ravulizumab is to be used for participants with a confirmed diagnosis of COVID-19 who clinically or diagnostically present with deteriorating renal function. Ravulizumab causes immediate and sustained inhibition of the terminal complement cascade. The use of ravulizumab could ameliorate COVID-19 induced kidney injury due to TMA, shorten hospital stay, and improve the overall survival.

This clinical trial aims to carry out research on the effect on hemoglobin and renal function of intravenous administration of iron dextran as a repletion strategy in patients with iron deficiency anemia and acute kidney injury, in which the patient may benefit from this drug as it is expected to correct anemia, ferropenia and renal function parameters, when compared with a control group (placebo), the safety of the drug will also be assessed by recording adverse effects. The investigators will point out with the patient the risks and benefits of their inclusion in this type of study and the investigators will attend to all the doubts that are generated, as well as immediately report to the research ethics committee any serious adverse effects. The results will be presented at national and international conferences and will be published in high-impact journals, and will also be the subject of a thesis to achieve the title of specialist.

OCE-205 is being tested to treat participants who have developed Hepatorenal Syndrome-Acute Kidney Injury as a complication of cirrhosis with ascites. The study aims are to evaluate the safety and efficacy of OCE-205 at various doses. Participants will receive treatment by intravenous infusion. Participants will continue with this treatment until participants meets primary endpoint or any discontinuation criteria.

Acute kidney injury (AKI) is a frequent disease in conventional hospital departments and in intensive care units. It's associated with a high risk to develop chronic kidney disease (CKD), even after a single small AKI episode. It's also associated with an important morbi-mortality, particularly cardiovascular (CV). Some studies have already showed a link between AKI and CV risk but pathologic mechanisms implicated are still unknown. In AKI and CKD, numerous substances, called uremic toxins (UT) are accumulating in blood. In CKD, those toxins, and particularly Indoxyl sulfate (IS), are known to have cardiac and vascular deleterious consequences. However, in AKI, whether acute accumulation of UT may trigger CV complications is unknown. The purpose of this study is that during AKI, a high UT concentration, in particular IS, would be associated with early vascular and cardiac dysfunctions that can be characterized by the persistence of an accelerated pulse wave velocity (PWV). The main objective is to evaluate the correlation between UT concentrations (especially IS) and arterial stiffness (PWV measurement) at three months of an AKI episode in conventional hospital departments and in the intensive care unit of nephrology.

Kidney disease in its chronic or acute form shares many risk factors for initiation, progression and prognosis with an increase in morbidity and mortality, the length of hospitalization and the cost associated with stages of increasing severity. Its overall estimated prevalence in the general population is 13% and 0.5% from stage 4, for which referral to a nephrologist is recommended to reduce mortality, slow progression of renal disease and better prepare for treatment by renal replacement. Acute kidney injury (AKI) is defined as a sudden increase in serum creatinine (Scr) with a prognostic classification of increasing severity. The population with chronic kidney disease (CKD) is often hospitalized and is frequently complicated by AKI, however CKD is asymptomatic for a long time, requiring structure screening in populations at risk. Performing Scr assays during hospitalization is an opportunity to screen patients with severe CRD or ARI requiring specialized treatment during and after hospitalization. A nephrological opinion is recommended for patients with severe CKD and AKI. Based on preliminary studies "MRC GARD" (NCT02938611) and "ARI TARGET" (NCT03192189), the study investigators identified the frequency of patients with increased Scr corresponding to stages ≥4 of CKD and to stage1b of ARI during their hospitalization. They found that 50% of patients hospitalized with a severe AKI had a CKD prior to their hospitalization. The use of dosages of Scr during hospitalization has been studied for AKI but without targeting high-risk subgroups and with discordant results. The study investigators plan to carry out a pragmatic study to show that an intervention combining alerts with Scr dosage to detect severe forms of CRD and AKI during hospitalization associated with the systematic intervention of a specialized dedicated team associating nephrologist and pharmacist to the scale of a GHT will improve patient and renal survival 1 year after screening.

Acute kidney injury (AKI), or worsening kidney function, is a common complication after liver transplantation (20-90% in published studies). Patients who experience AKI after liver transplantation have higher mortality, increased graft loss, longer hospital and intensive care unit stays, and more progression to chronic kidney disease compared with those who do not. In this study, half of the participants will have their body temperature cooled to slightly lower than normal (mild hypothermia) for a portion of the liver transplant operation, while the other half will have their body temperature maintained at normal. The study will evaluate if mild hypothermia protects from AKI during liver transplantation.

Multiple lines of evidence support a central role of iron in causing acute kidney injury (AKI), including the finding that prophylactic administration of iron chelators attenuates AKI in animal models. Patients undergoing cardiac surgery may be particularly susceptible to iron-mediated kidney injury due to the profound hemolysis that often occurs from cardiopulmonary bypass. The investigators will test in a phase 2, randomized, double-blind, placebo-controlled trial whether prophylactic administration of deferoxamine decreases the incidence of AKI following cardiac surgery.
