Preformed antibodies detected by cytotoxic assay or multibead array decrease liver allograft survival: role of human leukocyte antigen compatibility.

The significance of human leukocyte antigen (HLA) compatibility and preformed antibodies in liver transplantation remains unclear. The objectives of this study were to evaluate, in a single-center cohort comprising 896 liver transplants, whether the degree of donor-recipient compatibility and preformed antibodies modified graft survival. Univariate Kaplan-Meier analysis demonstrated that donor-recipient HLA compatibility had a marginal impact on allograft survival.

Peripheral blood lymphocyte populations in end-stage liver diseases.

Goals/background: The aim of this study was to decipher whether end-stage liver failure modifies peripheral blood lymphocytes (PBL) in a homogeneous manner, independently of the base pathology, or, if on the contrary, PBL subsets show a different profile in each hepatic disease.

Methods: We studied PBL subsets in 71 patients with end-stage liver disease, before liver transplant, and 74 healthy controls by flow cytometry. The results were statistically compared between patients and controls, and cohorts of patients classified according to their base pathology.
