ABSTRACT
AIM:
To increase the number of available grafts.METHODS:
This is a single-center comparative analysis performed between April 1986 and May 2016. Two hundred and twelve liver transplantation (LT) were performed with donors ≥ 70 years old (study group). Then, we selected the first cases that were performed with donors < 70 years old immediately after the ones that were performed with donors ≥ 70 years old (control group).RESULTS:
Graft and patient survivals were similar between both groups without increasing the risk of complications, especially primary non-function, vascular complications and biliary complications. We identified 5 risk factors as independent predictors of graft survival recipient hepatitis C virus (HCV)-positivity [hazard ratio (HR) = 2.35; 95% conï¬dence interval (CI) 1.55-3.56; P = 0.00]; recipient age (HR = 1.04; 95%CI 1.02-1.06; P = 0.00); donor age X model for end-stage liver disease (D-MELD) (HR = 1.00; 95%CI 1.00-1.00; P = 0.00); donor value of serum glutamic-pyruvic transaminase (HR = 1.00; 95%CI 1.00-1.00; P = 0.00); and donor value of serum sodium (HR = 0.96; 95%CI 0.94-0.99; P = 0.00). After combining D-MELD and recipient age we obtained a new scoring system that we called DR-MELD (donor age X recipient age X MELD). Graft survival significantly decreased in patients with a DR-MELD score ≥ 75000, especially in HCV patients (77% vs 63% at 5 years in HCV-negative patients, P = 0.00; and 61% vs 25% at 5 years in HCV-positive patients; P = 0.00).CONCLUSION:
A DR-MELD ≥ 75000 must be avoided in order to obtain the best results in LT with donors ≥ 70 years old.Palavras-chave
