Filter by:Solid organ transplant candidates will undergo serological screening for HHV8 at time of listing and transplantation. In the event of a recipient/donor mismatch R-/D+ or in the presence of a seropositive recipient (R+), blood levels of HHV8 DNA will be monitored together with specific IGRA for HHV8.
This study measures the safety, feasibility, and efficacy of viral-specific T cells (VST) against BK Virus (BKV) in adult kidney transplant recipients. Participants are expected to be on study for 52 weeks.
The working hypothesis is that hypertension during the first post-transplant trimester is partly explained by the patient's hypervolemia. The main objective of the single-center observational study "HTA ô Connect" is to study the relationship between hypertension and extracellular hyperhydration, thanks to repeated self-measurements of blood pressure and impedancemetry between the 30th and the 90th day post-transplant, in 150 incident kidney transplant patients from our department, the ITUN (Institute of Urology-Nephrology Transplantation). The study population involves 150 incident kidney transplant patients, presenting to the Nantes University Hospital Transplant Institute for 1 month (D30), and presenting with hypertension ≥ 140/90mmHg and not treated with a diuretic. Data collected at the patients' homes will be used to establish a relationship between blood pressure and extracellular water volume. The data collected will not be used to follow up patients who participated in the study in this first stage of exploration.
This study is a multicentric randomized controlled trial comparing two groups of patients undergoing single or dual kidney transplantation from deceased donors. To reduce perioperative complications optimal fluid management is essential in patients undergoing kidney transplantation. Heart rate, Medium Arterial Pressure (MAP), Central Venous Pressure (CVP), and urine output have been proposed in the literature to guide perioperative fluid therapy. These criteria are routinely applied in clinical practice; however these criteria have shown low sensitivity and poor predictive of postoperative complication, especially if used alone. The traditional approach in renal transplantation is the volume infusion guided whit CVP to the point of no further fluid responsiveness, but this can lead to excess fluid which can damage the endothelial glycocalyx and lead to organ failure for a fluid shift into the interstitial space. As a way to reduce postoperative complications in surgical patients, in recent years, several studies have examined Perioperative Goal Directed Therapy (PGDT) as fluid administration guided by optimization of preload with the use of algorithms based on fluids, inotropes and/or vasopressors to achieve a certain goal in stroke volume (SV), cardiac index (CI), or oxygen delivery (DO2). However results regarding the potential role of PGDT cannot be considered definitive, because the various studies on the subject have not all conformed to the same methods and have not uniformly applied the same measurements, so their results regarding the potential role of PGDT cannot be considered definitive. The aim of this work is to compare the effects of PGDT with conventional fluid therapy in patients undergoing kidney transplantation achievable through implementation of the non invasive monitoring.
Due to organ shortage in kidney transplantation (KT) several strategies have been implemented in an attempt to increase donor pool utilization, including transplantation of extended criteria donor (ECD) allografts. While the transplantation of ECD organs saves patients from waiting-list dropout, these pre-damaged organs exhibit an increased susceptibility to further injury during organ storage and transplantation. Static cold storage (SCS) involves the transportation of procured donor kidneys on ice and has remained the gold standard for organ preservation for decades. SCS relies on hypothermia to reduce cellular metabolism and oxygen demand while achieving a prolonged preservation time of organs. Upon reperfusion, the reintroduction of oxygen to the ischemic kidney leads to a respiratory burst with massive production of mitochondrial reactive oxygen species and subsequent sterile inflammation of the entire organ. This ischemia-reperfusion injury (IRI) is a central predictor of graft and patient survival. Current clinical preservation strategies are unable to meet the challenges of ECD allograft transplantation and there is a great demand to optimize preservation techniques for such high risk ECD allografts. Currently, two main paradigms prevail in the clinical approach to kidney allograft machine perfusion (MP) in regard to optimized preservation techniques: while end-ischemic hypothermic (HMP) and hypothermic oxygenated MP (HOPE) may be seen as dynamic alternatives of the traditional organ preservation based on hypothermia-induced deceleration of metabolism could not proof a beneficial effect on delayed graft function or primary graft failure, the impact of normothermic perfusion (NMP) on ECD kidney allografts is still missing. NMP aims at re-equilibration of cellular metabolism by preserving the organ at physiological temperatures whilst ensuring sufficient oxygen and nutrient supply. The present trial was therefore designed to provide first level-II evidence for NMP in human KT after donation after brain death (DBD). In total, 194 human kidney grafts will be randomized to either 4 hours of NMP directly before implantation (intervention group; n = 97) or to SCS (control group; n = 97) prior to transplantation. The primary endpoint will be kidney function after 6 months (6-months eGFR). Secondary endpoints include kidney function after 3 and 12 months, incidence of delayed graft function (DGF), primary non-function (PNF) and surgical complications assessed by the comprehensive complication index (CCI).
This study will evaluate the safety, PK, and efficacy of AT 1501 in patients undergoing kidney transplantation.
Assessment of changes of renal hemodynamics by multiparametric MRI after closure of AVF access.
Lower serum bicarbonate levels, even within the normal laboratory range, in kidney transplant recipients (KTRs) are associated with an increased risk of graft loss, cardiovascular events and mortality. Because acid retention is common in KTRs, it is plausible that alkali therapy in KTRs may also result in improved vascular and graft function. The investigators will perform a randomized, double-blinded, placebo-controlled, 12 month study in 120 KTRs to examine the effect of sodium bicarbonate therapy on surrogate markers of CVD and graft function. The overall hypothesis is that treatment with bicarbonate will improve indicators of vascular and graft function in KTRs by decreasing complement activation.
Cardiovascular diseases are among the most common causes of death in kidney transplant patients. Physical activity is of great importance in preventing cardiovascular diseases after transplantation. Although regular physical activity is recommended in international guidelines to prevent post-transplant mortality and morbidity in kidney transplant patients, studies have shown that patients do not follow regular physical activity instructions.The aim of our project is to examine the effect of pedometer-assisted physical activity on metabolic parameters after kidney transplantation.
This study will be a randomized, double-blind, placebo-controlled clinical trial comparing the SGLT2 inhibitor dapagliflozin to placebo in 52 kidney transplant recipients (KTR) with or without pre-existing type 2 diabetes (T2D) or post-transplant diabetes mellitus (PTDM). The primary outcome of the trial is to determine if dapagliflozin is superior to placebo in reduction of blood pressure in KTR.
