Angiotensin 2 for Hepatorenal Syndrome
Hepatorenal SyndromeCirrhosis2 moreHepatorenal syndrome (HRS) is a disease in which patients with cirrhosis (end stage liver failure) develop secondary kidney injury and failure. The current treatment available in the United States is a combination of octreotide and midodrine, which are meant to decrease the release of those hormones and raise the blood pressure, respectively, which would increase blood flow to the kidneys. Angiotensin 2 (Ang2) is a new vasopressor drug that was approved by the FDA in December 2017 for patients with low blood pressure and has been shown to have similar effects to octreotide and midodrine. This study will investigate whether Ang2 reverses HRS among patients admitted to the intensive care unit (ICU) at Ronald Reagan Medical Center. Our study population will be patients with HRS who are already or will be admitted to the ICU. HRS will be defined by new internationally accepted guidelines published by the International Club of Ascites. All patients who are consented will undergo an Ang2 response trial, where low-dose Ang2 will be administered for 4 hours to see how the patients respond. This will help us characterize the nature of the patients' kidney failure for later analysis. Patients will then be randomized into the control group or the study group. Patients in the control group will receive octreotide (a subcutaneous injection) and midodrine (an oral drug). Patients in the study group will continue receiving intravenous infusion of Ang2. Patients in both groups will also receive albumin, a protein found commonly in human blood. Treatment will continue in both groups for four days, until complete reversal of HRS, dialysis, or death. Our primary outcome will be rate of reversal of HRS, defined as improvement in kidney function.
Comparison of Slow Efficiency Daily Dialysis (SLEDD) With Unfractionated Heparin Versus Citrasate...
Acute Kidney InjuryHemodialysisThe purpose of this study is to compare the feasibility, safety and efficacy of hemodialysis with unfractionated heparin compared to hemodialysis with Citrasate in Critically Ill Patients.
Angiotensin in Septic Kidney Injury Trial
Acute Renal FailureSepsis1 moreThe purpose of this study is to determine the effect of a systemic infusion of angiotensin II on haemodynamics and urine output in critically ill patients with severe sepsis/septic shock and acute renal failure. It will also help determine the feasibility of conducting a definitive and adequately powered randomised controlled trial of angiotensin II in such patients that would assess mortality and need for renal replacement therapy as endpoints.

Angiotensin-Converting Enzyme Polymorphism and Acute Renal Failure (ECAREA)
Kidney FailureAcute1 moreAssociations between angiotensin-converting enzyme gene polymorphism and occurrence and outcome of ARDS, and with respiratory complications post cardiopulmonary bypass have already been demonstrated. Based on physiological effects of angiotensin II, we hypothesized that the I allele of the angiotensin-converting enzyme Insertion/Deletion polymorphism may be associated with a higher risk of acute renal failure in critically ill patients.
Trial for the Early Identification of Acute Kidney Injury
Acute Kidney InjuryPrevise is a novel, software-based clinical decision support (CDS) system that predicts acute kidney injury (AKI). Previse uses machine learning methods and information drawn from the electronic health record (EHR) to identify the early signs of acute kidney injury; by doing so before the clinical syndrome of AKI is fully developed, Previse can give clinicians the time to intervene with the goals of preventing further kidney damage, and decreasing the sequelae of AKI. It has been demonstrated in retrospective work that Previse can predict AKI with high accuracy at long prediction horizons, but the tool has yet to be validated in prospective settings; therefore, in this project, the clinical utility of Previse will be assessed through an individually randomized controlled multicenter trial.
A Study of Cell Therapy in COVID-19 Subjects With Acute Kidney Injury Who Are Receiving Renal Replacement...
COVID-19Acute Kidney Injury1 moreThe purpose of this study is to assess the safety and tolerability of the investigational product, SBI-101, in subjects with an infectious etiology of Acute Kidney Injury (AKI). SBI-101 is a biologic/device combination product designed to regulate inflammation and promote repair of injured tissue using allogeneic human mesenchymal stromal cells. SBI-101 will be integrated into the renal replacement circuit and patients will be treated for up to 24 hours.
The Protective Effect of Pentoxifylline on Acute Kidney Injury
PentoxifyllineAcute Kidney InjuryAcute kidney injury (AKI) has a frequency of 7.0 % in hospital inpatients and is especially common in critically ill patients, in whom the prevalence of acute kidney injury is greater than 40% at admission to the intensive care unit if sepsis is present. Therefore, alternative strategies are required to confer better or more complete renoprotection for those who suffered from AKI. There had been many studies demonstrated that the phosphodiesterase inhibitor pentoxifylline (PTX) is a potent anti-inflammatory, anti-proliferative, and anti-fibrotic agent capable of attenuating experimental renal disease such as drugs, ischemic and sepsis induced AKI. We thereby design this controlled, non-randomized clinical trial, aiming at investigating the potential renoprotective efficacy of PTX, as compared to placebo, in 200 patients with AKI.
Minimizing Contrast Utilization With IVUS Guidance in Coronary Angioplasty to Avoid Acute Nephropathy...
Acute Kidney InjuryAcute Renal Failure1 moreContrast-induced acute kidney injury (CI-AKI) is an important adverse effect of percutaneous coronary interventions. Despite various efforts, very few preventive measures have been shown effective in reducing its incidence. The final volume of contrast media utilized during the procedure is a well- known independent factor affecting the occurrence of CI-AKI. Intravascular ultrasound (IVUS) has been largely used as an adjunctive diagnostic tool during percutaneous coronary intervention (PCI). When fully explored, IVUS provides precise information for guiding PCI, thereby reducing the usage of contrast media. Accordingly, the recent MOZART study demonstrated that IVUS may lead to a 2-3-fold decrease in the volume of contrast media during PCI. In the present study, the hypothesize that IVUS guidance, and its consequent reduction in the volume of contrast media, will in decrease the risk of CI-AKI after PCI, in comparison to standard angiography-guided intervention.
Effects of DPP4 Inhibitor on Cisplatin Induced Acute Kidney Injury
CancerCisplatin Adverse ReactionCisplatin is a potent chemotherapeutic agent, however, its nephrotoxicity manifested by acute kidney injury (AKI) often limits applicability. Dipeptidylpeptidase-4 (DPP4) inhibitors are well known to improve glucose intolerance by augmentation of endogenous glucagon like peptide (GLP-1) and glucose-dependent insulinotropic peptide (GIP). DPP4 inhibitor also has the potential anti-apoptotic and renoprotective effect in a mouse model of cisplatin-induced AKI. This is a single-center, randomized, double-blind, parallel-group, placebo-controlled, prospective study to investigate the renoprotective effect of DPP4 inhibitor on cisplatin-induced AKI. A total 182 patients, who are scheduled to treat with cisplatin, will be recruited and randomly assigned to either Gemigliptin or placebo groups. Subjects will take study drugs for 8 days starting from one day before cisplatin treatment. Serum creatinine (Cr) and estimated glomerular filtration rate (eGFR) will be measured at 7 days after cisplatin treatment.
