Clinical use of a bioartificial liver in the treatment of acetaminophen-induced fulminant hepatic failure.

Patients with acetaminophen-induced fulminant hepatic failure (FHF) who meet the King's College Hospital criteria have a high mortality risk (>90%) if they do not undergo liver transplantation. We have developed a treatment strategy for these patients based on the use of an extracorporeal bioartificial liver (BAL) support system. In this study, we report the results of the clinical application of BAL support in patients with acetaminophen-induced FHF.

Intracranial pressure during liver transplantation for fulminant hepatic failure.

During orthotopic liver transplantation (OLT) for fulminant hepatic failure (FHF), some patients develop cerebral injury secondary to intracranial hypertension. We monitored intracranial pressure (ICP) and cerebral perfusion pressure (CPP) before and during OLT in 12 FHF patients undergoing transplantation. All four patients who had normal ICP preoperatively maintained normal ICP/CPP throughout OLT.

Treatment of severe liver failure with a bioartificial liver.

Orthotopic liver transplantation (OLT) is the definitive therapy for severe liver failure. However, many patients die before an organ becomes available, mostly from cerebral edema. To provide temporary liver support, we developed a bioartificial liver (BAL) based on porcine hepatocytes and a charcoal column.

Clinical experience with a bioartificial liver in the treatment of severe liver failure. A phase I clinical trial.

Objective: The purpose of this study was to develop a bioartificial liver (BAL) to treat patients with severe liver failure until they can be either transplanted or recover spontaneously.

Summary Background Data: Severe acute liver failure is associated with high mortality. Liver transplantation has emerged as an effective therapy for patients who did not respond to standard management.
