ABSTRACT BACKGROUND: Liver transplantation (LT) is the only treatment that can provide long-term survival for patients with acute-on-chronic liver failure (ACLF). Although several studies identify prognostic factors for patients in ACLF who do not undergo LT, there is scarce literature about prognostic factors after LT in this population. AIM: Evaluate outcomes of ACLF patients undergoing LT, studying prognostic factors related to 1-year and 90 days post-LT. METHODS: Patients with ACLF undergoing LT between January 2005 and April 2021 were included. Variables such as chronic liver failure consortium (CLIF-C) ACLF values and ACLF grades were compared with the outcomes. RESULTS: The ACLF survival of patients (n=25) post-LT at 90 days, 1, 3, 5 and 7 years, was 80, 76, 59.5, 54.1 and 54.1% versus 86.3, 79.4, 72.6, 66.5 and 61.2% for patients undergoing LT for other indications (n=344), (p=0.525). There was no statistical difference for mortality at 01 year and 90 days among patients with the three ACLF grades (ACLF-1 vs. ACLF-2 vs. ACLF-3) undergoing LT, as well as when compared to non-ACLF patients. CLIF-C ACLF score was not related to death outcomes. None of the other studied variables proved to be independent predictors of mortality at 90 days, 1 year, or overall. CONCLUSIONS: LT conferred long-term survival to most transplant patients. None of the studied variables proved to be a prognostic factor associated with post-LT survival outcomes for patients with ACLF. Additional studies are recommended to clarify the prognostic factors of post-LT survival in patients with ACLF.

ABSTRACT BACKGROUND: Liver transplantation is a complex and valuable therapy. However, complications that burden postoperative quality of life, such as incisional hernia, are to be better elucidated, such as risk factors and prophylactic measures. AIM: This study aimed to define the rate of incisional hernia in patients who underwent liver transplantation in a population in southern Brazil and to assess the related risk factors in order to establish measures for prior optimization and specific prophylactic care in the future. METHODS: Patients undergoing adult Liver transplantation from January 2004 to November 2020 were retrospectively analyzed, assessing demographic features, surgical outcomes, and predisposing factors. RESULTS: Among 261 liver transplantation patients included, incisional hernia was diagnosed in 71 (27.2%). Of the 71 incisional hernia patients, 28 (39.4%) developed IH during the first post-transplant. Majority of the patients were male (52/71, 73.2%); of the 71 patients, 52 had hepatitis C virus (HCV) and 33 (46.5%) had hepatocellular carcinoma (HCC). Male gender (p=0.044), diabetes mellitus (p=0.008), and acute cellular rejection (p

Introdução: Pacientes em acute on chronic liver failure (ACLF) apresentam características distintas daquelas apresentadas por pacientes hepatopatas não ACLF. O grau de ACLF impacta no desfecho com ou sem o transplante, havendo divergências na literatura principalmente no que tange ao prognóstico pós-transplante. Objetivos: Revisar os diferentes aspectos dos pacientes em ACLF, abrangendo os conceitos da síndrome adotados por diversas instituições, o tratamento das complicações, e descrever o conhecimento acerca dos desfechos com ou sem transplante dos portadores da síndrome reportados na literatura. Métodos: Foram incluídos 22 artigos encontrados na busca de bases de dados PubMed, Medline e Biblioteca Eletrônica Científica Online (SciELO) com os descritores “ACLF definitions” e “Liver transplantation ACLF”. Os conceitos e dados apontados nos textos selecionados foram comparados e utilizados como base para redigir este artigo. Resultados: Existem algumas diferenças na definição da síndrome, variando especialmente entre os países do Ocidente e os do Oriente. Pacientes aguardando transplante hepático em ACLF apresentam características distintas daquelas apresentadas por pacientes não ACLF. O grau de ACLF também impacta no desfecho com ou sem o transplante, havendo divergências na literatura principalmente no que tange ao prognóstico pós-transplante dos pacientes em ACLF 3, com tendência cada vez maior na indicação do transplante mesmo para esses pacientes. Conclusões: Os desfechos variam entre pacientes em ACLF de acordo com o grau da doença. O transplante hepático tem sido mais frequentemente indicado em ACLF 3, tendo o tempo de espera impactado os resultados. São necessários mais estudos para definir quais subgrupos de pacientes se beneficiam mais do transplante hepático.
