Acute-on-chronic liver failure: a retrospective review of cases at a transplantation center in Brazil.

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.

Exercise training as an intervention for frailty in cirrhotic patients on the liver transplant waiting list: A systematic review.

Background: The existing literature suggests that exercise for cirrhotic patients is safe and favours significant improvement to their physical capacity. However, exercise training for this population and how to deliver activities, especially in severe stages of the disease and while waiting for a liver transplant (LT), remain undefined.

Aim: To review the existing exercise prescriptions for cirrhotic patients on the waiting list for LT, their results for frailty evolution and their effect on clinical outcomes.

Establishing a HOPE Program in a Real-life Setting: A Brazilian Case Series.

Background: Although hypothermic oxygenated perfusion (HOPE) improves posttransplant outcomes, setting up machine perfusion programs may be subjected to specific obstacles under different conditions. This study aims to describe the establishment of HOPE in a real-life setting in Brazil.

Methods: Extended criteria donors in donation after brain death organs preserved by HOPE were accepted for higher-risk candidates needing expedited transplantation, perceived as those who would benefit most from the technique because of its limited availability.

Current and future perspectives on acute-on-chronic liver failure: Challenges of transplantation, machine perfusion, and beyond.

Acute-on-chronic liver failure (ACLF) is a syndrome that occurs in patients with chronic liver disease and is characterized by acute decompensation, organ failure and high short-term mortality. Partially due to the lack of universal diagnostic criteria, the actual ACLF prevalence remains unclear; nevertheless, it is expected to be a highly prevalent condition worldwide. Earlier transplantation is an effective protective measure for selected ACLF patients.

Update on the management and treatment of viral hepatitis.

This review aims to summarize the current evidence on the treatment of viral hepatitis, focusing on its clinical management. Also, future treatment options and areas of potential research interest are detailed. PubMed and Scopus databases were searched for primary studies published within the last ten years.

Minor salivary gland biopsy for the diagnosis of familial amyloid polyneuropathy.

The diagnosis of Val30Met familial amyloidotic polyneuropathy (FAP) is based on genetic tests, clinical manifestations, familial history and biopsy of peripheral tissues (e.g. rectum, abdominal fat pad, sural nerve, and minor salivary gland) to confirm the presence of amyloid deposits.

Diagnostic Accuracy of Transient Elastography for Detecting Liver Fibrosis After Liver Trannsplantation: A Specific Cut-Off Value Is Really Needed?

Introduction: Liver transplant recipients often perform liver biopsy (LB), specially in the context of potentially recurring diseases, such as hepatitis C infection. However, the LB has risks of complications, despite being the gold standard. Transient elastography (TE) is a noninvasive method comparable to the LB to evaluate liver fibrosis in various settings, but its accuracy among transplant recipients is not fully understood.

List and liver transplant survival according to waiting time in patients with hepatocellular carcinoma.

The time that patients with hepatocellular carcinoma (HCC) can safely remain on the waiting list for liver transplantation (LT) is unknown. We investigated whether waiting time on the list impacts transplant survival of HCC candidates and transplant recipients. This is a single-center retrospective study of 283 adults with HCC.

Liver transplant outcome: a comparison between high and low MELD score recipients.

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 > or = 30, MELD < 30, and hepatocellular carcinoma.

Hepatocellular carcinoma recurrence among liver transplant recipients within the Milan criteria.

Introduction: Orthotopic liver transplantation (OLT) is an excellent option for patients with unresectable hepatocellular carcinoma (HCC) within the Milan criteria. Recurrence of HCC has a severe impact on post-OLT survival. In this study, we performed an analysis of post-OLT recurrence pattern of HCC.

Clinical profile and liver explant findings in patients with and without pretransplant downstaging for hepatocellular carcinoma.

Introduction: Since August 2010, The Brazilian National Transplantation System has allowed performance of liver transplantation (OLT) for patients with hepatocellular carcinoma (HCC) beyond the Milan criteria (MC) who have been successfully treated with preoperative downstaging (DS). Herein we sought to compare the clinical profiles and liver explant findings among patients with versus without preoperative DS.

Methodology: Prospective cohort of patients with HCC within and beyond the MC undergoing OLT.

Results of retransplantation for primary nonfunction in a single center.

Introduction: Early graft dysfunction has a negative impact on allograft and patient survivals, evolving to retransplantation or death in the majority of cases. The outcome of a second liver transplant is usually worse than the first procedure. Considering the increasing number of recipients on the waiting list, and the discrepancy between the number of accessible donors and recipients, we sought to analyze the results of retransplantation at our institution and at those within the State of Sao Paulo.

Antibody-mediated rejection: hyperacute rejection reality in liver transplantation? A case report.

Hyperacute rejection is rare among ABO-compatible liver transplantations. The mechanism is donor preformed antibodies causing graft loss within a few days. Herein, we have described a case of an ABO-compatible liver transplantation that underwent hyperacute rejection, needing retransplantation for treatment.

Twenty years of liver transplantation in Brazil.

This paper summarizes the 20 years of liver transplantation in Brazil, in the context of the Western world scenario. More than 5000 liver transplantations have been performed in the country since September 1, 1985. The living-donor liver transplantation, one of the landmarks in liver transplantation, was first described by our team in 1989.
