A new bioartificial liver support system using porcine hepatocytes shows promise for bridging patients with acute liver failure to transplantation, improving survival. Further studies are needed for chronic liver disease patients.

Area of Science:

  • Hepatology
  • Biomedical Engineering
  • Transplantation Medicine

Background:

  • Fulminant hepatic failure (FHF) carries a high mortality rate (approaching 90%), with cerebral edema being a primary cause of death.
  • Liver transplantation improves survival but is limited by donor organ shortage, leaving many FHF patients at risk.
  • Existing blood detoxification methods have not achieved wide acceptance due to incomplete understanding of liver failure and inadequate clinical trials.

Purpose of the Study:

  • To develop and evaluate an extracorporeal liver assist system to support patients with liver failure until transplantation or native liver recovery.
  • To assess the efficacy of a porcine hepatocyte-based bioartificial liver support system in patients with acute liver failure and decompensated chronic liver disease.

Published on: September 13, 2014

  • A preliminary clinical study utilizing a porcine hepatocyte-based liver support system.
  • Treatment of patients with acute liver failure awaiting transplantation and patients with acute exacerbation of chronic liver disease.

    • Main Results:

    • The bioartificial liver support system successfully bridged patients with acute liver failure to liver transplantation with excellent survival.
    • No significant benefit was observed in patients with decompensated chronic liver disease, suggesting potential need for earlier or longer treatment.

    Conclusions:

    • Porcine hepatocyte-based liver support systems demonstrate potential as a bridge to transplantation for acute liver failure.
    • Further prospective controlled trials are required to establish efficacy in both acute liver failure and chronic liver disease populations.
