Filter by:This study was designed to compare 3 immunosuppression regimens: sirolimus and tacrolimus versus everolimus and tacrolimus versus mycophenolate and tacrolimus. The primary outcome is the incidence of cytomegalovirus infection / disease, a relevant medical need in the absence of pharmacological prophylaxis.
The purpose of this study is to assess relationship between tacrolimus concentrations determined via whole blood MITRA assay method with those determined using the established and validated whole blood venepuncture method using samples taken from liver and kidney transplant participants.
The pharmacokinetics of tacrolimus (TAC) are characterized by high inter- and intra-individual variability with narrow therapeutic range. Currently, the limiting point of Tac drug monitoring is the inability to individualize doses during the first few days after transplantation. Our group developed a population pharmacokinetic model (PPK) identifying CYP3A4 * 22 and CYP3A5 * 3 polymorphisms and hematocrit as explanatory variables of the observed variability in pre-dose (Co) concentrations. According to this model, the proportion of patients that do not reach the therapeutic target is 40
Previous studies have shown that elderly patients experience higher trough levels of tacrolimus and are more sensitive to the effects of medications, they experience higher occurrence and severity of such medication related toxicities. Therefore, the investigators hypothesize that by transitioning patients from tacrolimus immediate release to Envarsus ®, the peak-dose effect will be eliminated or attenuated, leading to a significant decrease in neurocognitive toxicities in the older patient population.
Metabolic acidosis is associated with vascular endothelial dysfunction and is a common complication in patients who have received a kidney transplant. Kidney transplant recipients (KTR) with lower serum bicarbonate levels, even within the normal range, have an increased risk of graft loss and mortality. The investigators propose a prospective, double-blind, randomized, placebo-controlled, 18-week crossover pilot study to examine the effects of sodium bicarbonate on vascular endothelial function, graft function, and cognitive function in 20 KTR patients.
It was previously suggested an improvement of graft survival in ABO/HLA incompatible kidney transplantation (KT) compared with HLA (human leukocyte antigen) incompatible transplantation. Here, the investigators would analyse clinical, biological and histological results of ABO/HLA incompatible kidney transplant recipients, comparing with ABO or HLA compatible kidney transplantation.
Antibody mediated rejection (ABMR) is a unique, significant and often severe form of allograft rejection. This single center, phase I/II, open label single-arm exploratory study focuses on enrolling ten patients with biopsy proven chronic antibody medicated rejection and/or donor specific antibody present at time of biopsy. Patients who qualify will be receiving clazakizumab (anti-IL6 monoclonal antibody) monthly x six doses. A protocol biopsy will be performed at 6 months and if improvement is seen, patients will continue another six doses for up to 12 months. For those completing 12 doses, there will be a 12 month protocol biopsy. For those who only received six doses, the next and last study visit will be at 12 months from enrollment. Total study duration is 12 months.
Our primary goal is to investigate any hidden burden upon the grafted kidney from the increase of serum fluoride resulted from sevoflurane, versus isoflurane.
The primary objective of this study is to demonstrate the safety and efficacy of cellular immunotherapy with MDR-101 for induction of functional immune tolerance in recipients of human leukocyte antigen (HLA)-matched, living donor kidney transplants.
