Filter by:The major hypothesis to be tested is that there was no difference in the clinical outcome between 7(short-course) and 14(traditional-course) days of antibiotic treatment for asymptomatic bacteriuria early after kidney transplantation.
The purpose of this study is to investigate local activation of the coagulation system in the kidney graft during organ preservation and during early reperfusion in adult kidney transplantation. Generation of thrombin and fibrin as well as activation and inhibition of fibrinolysis will be investigated. Influence of these events on delayed graft function (DGF) and acute cell-mediated rejection will be evaluated.
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 investigate the efficacy and safety of allogeneic bone marrow-derived mesenchymal stem cells (BM-MSCs) on chronic antibody-mediated rejection (cAMR) after kidney transplantation. Chronic AMR is diagnosed according to Banff criteria 2013 based on renal graft biopsy and donor specific antibodies (DSA) examination. cAMR patients are assigned to MSCs group or control group. Patients in control group are prescribed to current desensitization therapy including at least one of the following treatments: plasmapheresis (PP), intravenous immunoglobulin (IVIG), rituximab or Bortezomib, depending on individual pathological and immunological features (eg. DSA type and titer) of each study subjects. Patients in MSCs group receive additional BM-MSCs therapy besides desensitization treatments as in control group. Allogeneic BM-MSCs (1*10^6/kg) are intravenously administered every two weeks for four consecutive doses. All cAMR patients are followed up for one year. Renal function, DSA level, pathological features, patient/graft survival, and severe adverse events are monitored during the follow-up period. Immunological features of patients in both groups are consecutively examined.
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.
The purpose of this study is to transition patients who have been stable on Belatacept for one year after kidney transplant from standard 4-week to an investigational 8-week belatacept dosing schedule. The investigators hypothesize that renal function and acute rejection rates will be non-inferior with 8-week belatacept dosing.
A study to evaluate changes over time in renal function from baseline (time of conversion) up until five years post conversion in kidney transplant patients converted from tacrolimus twice daily (BD) formulations to a once daily formulation as Advagraf.
Endothelial lesions within the transplanted kidney are a major determinant of chronic allograft nephropathy. Epoxyeicosatrienoic acids (EETs) are endothelium-derived hyperpolarizing factors with anti-inflammatory, antiproliferative and vasodilator properties. The main goal of the investigators' study is to evaluate whether genetic polymorphisms of specific enzymes responsible for the bioavailability of EETs are associated with post-transplant kidney function. To this end, 80 kidney transplant recipients will be included. Prespecified genetic polymorphisms of CYP 2J2, CYP 2C8, CYP 2C9, CYP 2C9, CYP 2C19 and EPHX2 will be determined. Kidney function will be recorded 3, 6, 12 and 36 months after transplantation. Flow-mediated dilatation, EETs and circulating biomarkers of endothelial function will be measured in the radial artery. The expected results of this study to provide preliminary evidence supporting a beneficial role of an increase in the bioavailability of EETs in kidney transplant recipients.
The aim of this prospective, randomized study is to assess a subject's immunological status against hCMV before kidney transplantation by an hCMV-specific interferon (INF)-γ ELISPOT technique confirming previous results and establishing their statistical validity in order to determine whether this test could be used routinely in clinical practice to assess the risk of developing hCMV infection after renal transplantation and, ultimately, identify the most effective individual antiviral therapeutic strategy against hCMV.
The renal transplant patient is at high cardiovascular risk compared to the general population. The cardiovascular mortality represents one of the most important causes of late graft loss. Cardiovascular risk prediction tools applied to the general population, however, are caught failing on the population of kidney transplant and tend to underestimate the actual risk. Central blood pressure is the pressure imposed at large artery (aorta, carotid) and is directly related to the target organ (heart, kidney, brain). Central blood pressure could be a cardiovascular risk factor more robust and powerful than brachial blood pressure. Central blood pressure may in part explain the increased risk of cardiovascular disease in the population of kidney transplant patients. A cohort of 250 kidney transplant patients will be constituted with a measure of concomitant central hemodynamic monitoring to the annual review will be conducted. The main objective of this study is to describe the central blood pressure measured by oscillometric method in renal transplanted population.
