Tissue Analysis of Liver Grafts as a Predictor of Transplant Outcome.

Overview

Despite the good clinical results in terms of outcome with the application of HOPE prior to liver transplantation, very little is still known about the phenotypic and molecular changes that occur during perfusion/preservation during HOPE, particularly with regard to endothelial trophism and activation. Delving into these aspects would be very useful to allow personalised perfusion treatments in the future, thus improving the outcome of transplantation.

The primary aim of the study is the identification of specific 'endothelial signatures' (markers on tissue with immunohistochemistry and gene expression with RT-PCR) in liver grafts after HOPE treatment, predictive of transplant outcome. Interventional study without drug, including two cohorts of patients: (1) liver donors, on whom an allocation biopsy for organ quality will be performed (as standard of care); (2) liver recipients (from donors in cohort 1) on whom a study-specific biopsy will be performed as soon as the transplant has taken place (after vascular anastomoses with organ revascularisation). The study-specific biopsy constitutes the intervention of the study; patients will be treated according to the judgement of the physician and the information reported in the Technical Data Sheet of each product of any concomitant therapies administered according to clinical practice.
