Liver Transplantation in Patients With CirrHosis and Severe Acute-on-Chronic Liver Failure: iNdications and outComEs

Description

The aim of this study is to compare 1-year graft and patient survival rates after liver transplantation (LT) in patients with ACLF-2 or 3 at the time of LT, with patients with decompensated cirrhosis without ACLF-2 or 3 at the time of LT and also with transplant-free survival of patients with ACLF-2 or 3 not listed for LT.

Secondary objectives are as follows:

* To assess the proportion of patients with ACLF-2 or 3 referred to transplant team who are listed or not and reasons of this decision.
* To evaluate the outcomes of patients listed with ACLF-2 or 3 on the waiting list compared with those of patients listed with decompensated cirrhosis without ACLF-2 or 3.
* To define independent predictive factors of death/delisting on the waiting list for patients listed with ACLF-2 or 3 and develop a new prognostic model based on ACLF criteria to predict mortality on the waiting list and to improve the allocation of organs.
* To compare the characteristics of accepted grafts for patients listed with ACLF-2 or 3 with those of patients listed with decompensated cirrhosis without ACLF-2 or 3 and their impact on post-LT outcomes.
* To explore independent predictive factors of death after LT for patients transplanted with ACLF-2 or 3 to design futility criteria for LT.
* To compare post-LT survival rates of patients with ACLF-2 or 3 at listing and patients without ACLF at listing who develop ACLF-2 or 3 on the waiting list.
* To compare post-LT quality of life (QoL) for patients listed with ACLF-2 or 3 with those of patients listed with decompensated cirrhosis without ACLF-2 or 3.
