ABSTRACT Purpose: Acute-on-chronic liver failure (ACLF) is a leading cause of death in cirrhotic patients. This study aims to describe the outcomes of in-patients with ACLF at a liver transplantation (LT) center in Brazil. Methods: Retrospective study analyzing patient data from 2017 to 2022. Re-transplant cases and patients without previous chronic liver disease were excluded. The ACLF diagnosis was based on the European Association for the Study of the Liver-Chronic Liver Failure criteria and assessments repeated on days 3 and 7 after the initial diagnosis. Results: Among 381 patients, 10.49% (n = 40) were diagnosed with ACLF. Bacterial infection was the most common precipitating factor (45%). Kidney failure occurred in 65% of the cases. The 28-day mortality rate was 35% and varied according to ACLF severity at diagnosis, from single organ failure (ACLF-1) at 22% to three organ failures (ACLF-3) at 60%. Eighteen patients (45%) were transplanted with a 100% 28-day survival rate. For ACLF-3 cases at diagnosis (n = 15), the 28-day and 1-year survival rates with a transplant (n = 4) were 100% and 80%, respectively, and without transplant (n = 11), 10 and 0%, respectively. Conclusions: ACLF was associated with high mortality rates. LT was an effective therapeutic option, particularly for ACLF-3 cases.

OBJETIVO: Comparar MELDs altos e baixos, sua relação com a disfunção renal e o efeito no resultado do transplante. MÉTODOS: Realizou-se coleta prospectiva de dados em 237 transplantes de fígado (216 pacientes) entre março de 2003 e março de 2009. Pacientes com cirrose submetidos a transplante foram divididos em três grupos: MELD > 30, MELD < 30, e carcinoma hepatocelular. Insuficiência renal foi definida como uma diminuição de ± 25% na taxa de filtração glomerular estimada, observada 1 semana após o transplante. As medianas do MELD foram 35, 21, e 13 para os grupos MELD > 30, MELD < 30, e de carcinoma hepatocelular, respectivamente. RESULTADOS: Receptores com MELD > 30 tiveram mais dias na Unidade de Terapia Intensiva, maior período de internação, e receberam mais transfusões de sangue. Além disso, sua função renal melhorou após o transplante de fígado. Os demais grupos apresentaram diminuição da função renal. A mortalidade foi semelhante em todos os grupos, mas a função renal foi a variável mais importante associada com morbidade e tempo de internação hospitalar. CONCLUSÃO: Em receptores com escores MELD altos houve melhora da taxa de filtração glomerular 1 semana após o transplante de fígado.

OBJECTIVE: To compare low and high MELD scores and investigate whether existing renal dysfunction has an effect on transplant outcome. METHODS: Data was prospectively collected among 237 liver transplants (216 patients) between March 2003 and March 2009. Patients with cirrhotic disease submitted to transplantation were divided into three groups: MELD > 30, MELD < 30, and hepatocellular carcinoma. Renal failure was defined as a ± 25% decline in estimated glomerular filtration rate as observed 1 week after the transplant. Median MELD scores were 35, 21, and 13 for groups MELD > 30, MELD < 30, and hepatocellular carcinoma, respectively. RESULTS: Recipients with MELD > 30 had more days in Intensive Care Unit, longer hospital stay, and received more blood product transfusions. Moreover, their renal function improved after liver transplant. All other groups presented with impairment of renal function. Mortality was similar in all groups, but renal function was the most important variable associated with morbidity and length of hospital stay. CONCLUSION: High MELD score recipients had an improvement in the glomerular filtration rate after 1 week of liver transplantation.
