Liver support systems offer survival benefits for patients with liver insufficiency by removing toxic substances. Advanced extracorporeal therapies like MARS and Prometheus show promise, with stem cells representing future hope.

Area of Science:

  • Hepatology
  • Biomedical Engineering
  • Nephrology

Background:

  • Liver insufficiency leads to toxic substance accumulation and multi-organ involvement.
  • Patients often face mortality due to organ scarcity while awaiting transplantation.
  • Current treatments aim to bridge patients to transplantation or support organ recovery.

Purpose of the Study:

  • To review existing and novel liver support systems for managing liver insufficiency.
  • To evaluate the efficacy of extracorporeal detoxification technologies.
  • To discuss the potential of bioartificial livers and stem cell therapy.

Main Methods:

  • Review of extracorporeal liver support technologies, including charcoal hemoperfusion, resins, plasma exchange, and selective plasmapheresis.

  • Detailed examination of molecular adsorbent recirculation system (MARS) and Prometheus systems for enhanced detoxification.
  • Discussion of bioartificial liver concepts and emerging stem cell therapies.

    • Main Results:

    • Extracorporeal systems can perform detoxification, with bioartificial options potentially adding synthesis and regulation functions.
    • MARS has shown efficacy in treating hepatic encephalopathy, though survival data is limited.
    • Prometheus demonstrates promising initial results for broad detoxification, with large trials pending.

    Conclusions:

    • Liver support systems can provide survival benefits for patients with liver insufficiency.
    • Novel systems like MARS and Prometheus offer improved detoxification, particularly for protein-bound toxins.
    • Stem cell therapy holds significant future potential for end-stage liver disease.
