Article Synopsis
  • This study explored the molecular mechanisms of Fontan-associated liver disease (FALD) by examining gene expression differences in liver fibrosis among patients.
  • Researchers analyzed data from 106 adults with the Fontan circulation, identifying upregulated genes in those with advanced fibrosis and assessing clinical outcomes.
  • Findings revealed that patients with advanced fibrosis had increased inflammation and vascular development gene activity, but these did not predict clinical outcomes like serious complications.

Ischemia-reperfusion injury and its relationship with early allograft dysfunction in liver transplant patients.

Am J Transplant

February 2021

The Dumont-UCLA Liver Transplant Center, Division of Liver and Pancreas Transplantation, Department of Surgery, David Geffen School of Medicine at UCLA, Los Angeles, California, USA.

Ischemia-reperfusion injury (IRI) is believed to contribute to graft dysfunction after liver transplantation (LT). However, studies on IRI and the impact of early allograft dysfunction (EAD) in IRI grafts are limited. Histological IRI was graded in 506 grafts from patients who had undergone LT and classified based on IRI severity (no, minimal, mild, moderate, and severe).

Although CEACAM1 (CC1) glycoprotein resides at the interface of immune liver injury and metabolic homeostasis, its role in orthotopic liver transplantation (OLT) remains elusive. We aimed to determine whether/how CEACAM1 signaling may affect hepatic ischemia-reperfusion injury (IRI) and OLT outcomes. In the mouse, donor liver CC1 null mutation augmented IRI-OLT (CC1-KO→WT) by enhancing ROS expression and HMGB1 translocation during cold storage, data supported by in vitro studies where hepatic flush from CC1-deficient livers enhanced macrophage activation in bone marrow-derived macrophage cultures.

aDepartment of Medicine, Nephrology Division, Kidney Transplant Program bDepartment of Surgery, Division of Liver and Pancreas Transplantation, David Geffen School of Medicine at UCLA, The Dumont-UCLA Liver Transplant Center, Los Angeles, California, USA.

Purpose Of Review: There have been no well defined guidelines to determine whether a kidney transplant should be offered to liver transplant candidates who have chronic kidney disease (CKD) or prolonged acute kidney injury while awaiting a liver transplant. This article provides a review of current literature on risk factors for CKD progression after liver transplantation alone (LTA) in patients with pretransplant renal dysfunction and the utility of cystatin C (Cyst C) to assess renal function in cirrhotic patients. Studies evaluating risk factors for transplant futility are also discussed.

Intrahepatic cholangiocarcinoma (ICCA) comprises 10% of all cholangiocarcinoma (CCA). It can be divided into three macroscopic subtypes, the least common of which is characterized by intraductal growth and believed to be more amenable to good outcomes with surgical resection compared to other ICCA. Recently, the rare finding of oncocytic differentiation has been described in this subtype and termed <> (IOPN), but it remains unclear if the presence of oncocytes confers a different tumor behavior.

Objective: Hepatitis C (HCV) is now the most common indication for orthotopic liver transplantation (OLT). While graft reinfection remains universal, progression to graft cirrhosis is highly variable. This study examined donor, recipient, and operative variables to identify factors that affect recurrence of HCV post-OLT to facilitate graft-recipient matching.

October 2006

Dumont-UCLA Liver Transplant Center, David Geffen School of Medicine at UCLA, Department of Surgery, 10833 LeConte Ave, 77-132 CHS, Los Angeles, CA 90095, USA.

The hepatitis C virus (HCV) infects 3% of the world's population, or approximately 170 million people. Most of those acutely infected progress to chronic infection and are unresponsive to existing antiviral treatment. Over a 20-year period, chronic HCV infection leads to cirrhosis and the sequelae of end-stage liver disease, including hepatic encephalopathy, ascites, variceal haemorrhage and hepatocellular carcinoma.
