Immunosuppressive drugs can be completely withdrawn in up to 20% of liver transplant recipients, commonly referred to as 'operationally' tolerant. Immune characterization of these patients, however, has not been performed in detail, and we lack tests capable of identifying tolerant patients among recipients receiving maintenance immunosuppression. In the(More)
AIMS This prospective study investigated the effect of genetic polymorphisms in a biotransformation enzyme (CYP3A5) and a transporter protein (ABCB1) on tacrolimus (Tac) whole blood concentrations in renal transplantation, and more specifically on peripheral blood mononuclear cell (PBMC) drug concentrations, after renal transplantation.

Cord blood (CB) transplantations are associated with low graft-versus-host disease (GVHD). The pathophysiology of GVHD involves interaction and activation of different cell types, as lymphocytes and monocytes, and results in a cascade of cytokine production. After antigen or mitogen stimulation, CB monocytes release lower levels of cytokines than adult(More)
Hepatocyte transplantation is an investigational alternative to orthotopic liver transplantation to treat liver based inborn errors of metabolism. We report successful hepatocyte transplantation in a 4-year-old girl with infantile Refsum disease. Hepatocytes were isolated from the left liver segment of two male donors using a classic two-step perfusion(More)
OBJECTIVE To assess the respective impact of surgical and immunologic factors on patient/graft outcome and rejection after pediatric liver transplantation. SUMMARY BACKGROUND DATA Orthotopic liver transplantation (OLT) constitutes a validated therapeutic modality for acute liver failure and end-stage liver disease in children. Only a few large studies of(More)
BACKGROUND Tacrolimus (Tac) metabolism is mainly mediated by the cytochrome P450 3A (CYP3A) subfamily. Recently, it has been reported that kidney transplant recipients carrying the CYP3A4*22 decrease-of-function allele require lower Tac doses and are more at risk of Tac overexposure than CYP3A4*1/*1 patients. This effect was shown to be independent of the(More)
Xenoreactive natural antibodies (XNA) and complement activation are thought to be the 2 main factors responsible for the hyperacute vascular rejection (HVR) of discordant xenografts. The aim of this work was to study the role of IgM XNA in the HVR of guinea pig to rat cardiac xenografts, a discordant model. Adult LOU/C rats were depleted of circulating IgM(More)
