Active clinical trials for "Kidney Tubular Necrosis, Acute"

The goal of this pilot, randomized, single-blind clinical trial is to estimate the effect size of a high and low mean arterial pressure (MAP)-target algorithm among cirrhosis patients hospitalized with acute kidney injury. The main aims to answer are: • Does an algorithm that has low (<80 mmHg) and high (≥80) MAP-targets lead to significant differences in mean arterial pressure? • Are there any serious adverse events (e.g., ischemia) in a high blood pressure algorithm as compared to a low blood pressure algorithm? • Are there any differences in the incidence of AKI reversal in the high v. low MAP-target groups? Participants will be: 1) Randomized to a clinical algorithm that will either target a low (<80 mmHg) or high (≥80 mmHg) MAP. 2) Depending on their group, investigators will titrate commonly used medications to a specific MAP target. Researchers will compare the high and low MAP-target groups to see if these algorithms lead to significant changes in MAP, if they have any impact on AKI reversal, and if there are any adverse events in the high MAP-target group.

Ischemic acute tubular necrosis (ATN) is one of the main cause of acute kidney injury (AKI) in intensive care units (ICU). Sepsis and cardio-pulmonary bypass (CPB) are major providers. There is no validated tool to predict the evolution of AKI is ICU. Furosemide Stress Test (FST) may predict evolution of ATN-related AKI outside ICU in terms of progressive AKI, need for renal replacement therapy (RRT) or inpatient mortality with improved performance comparing to biomarkers. FST has not been validated in a prospective cohort in ICU in the settings of ischemic ATN. FURTHER aim to determine whether FST would be a useful tool to identify patients with slight to moderate AKI (KDIGO stage 1 and 2) who will evolve towards need for RRT following AKIKI (The Artificial Kidney Initiation in Kidney Injury ) delayed initiation criteria.

The purpose of this trial is to determine if the administration of allogeneic MSCs at defined doses is safe in patients who are at high risk of developing significant Acute Kidney Injury (AKI) after undergoing on-pump cardiac surgery.

This study is designed to investigate whether allogeneic bone marrow-derived mesenchymal stem cells (BM-MSCs) can promote function recovery in patients with poor early graft function after kidney transplantation from Chinese Donation after Citizen Death (DCD). DCD kidney transplant recipients with poor early graft function (with or without dialysis) post transplant are equally randomized into MSCs group or control group. Patients in MSCs group are administered MSCs treatment. Allogeneic BM-MSCs (1*10^6/kg) from third party are given intravenously for four consecutive doses every week after enrollment. Patients in control group receive placebo. Renal allograft function (eGFR), rejection, patient/graft survival and severe adverse events up to 12 months post enrollment are monitored.

This study is designed to determine the efficacy and safety of allogeneic bone marrow-derived mesenchymal stem cells in kidney transplantation from Chinese donation after citizen's death (DCD). A pair uremia patients receiving kidney grafts from a same donor are randomized into two groups: MSCs group and control group. Besides routine induction therapy (ATG or Basiliximab) and maintenance immunosuppressive drugs (low-dose Tacrolimus + MPA + prednisone), patients in MSCs group are administered MSCs treatment (1*10^6/kg). Allogeneic bone marrow-derived MSCs (1*10^6/kg) are given intravenously at day 0 (post renal reperfusion during surgery), day 7, day 14 and day 21. The renal allograft function, rejection, patient/graft survival and severe adverse events within 12 months post-transplant are monitored.

Acute Renal Failure (ARF) is defined by a severe, and usually reversible, glomerular filtration rate decreasing. Acute Tubular Necrosis (ATN) remain the major cause of ARF involving distress and destruction of tubular cells. This specific typology of ARF may evolve toward Chronic Renal Failure (CRF) concretizing a major public health issue. Predict the progression of ARF towards CRF appears essential. The investigators believe that the PIIINP and urinary NGAL biomarkers may constitute robust biomarkers of progression risk towards CRF.
