Management of acute liver failure

Area of Science:

• Hepatology
• Critical Care Medicine
• Transplantation

Background:

• Acute liver failure (ALF) presents significant management challenges.
• High mortality rates are associated with complications like cerebral edema and renal failure.
• Diverse etiologies contribute to ALF, including drug toxicity and viral infections.

Purpose of the Study:

• To review the experience in treating 620 patients with severe acute liver failure (grade 3 or 4 encephalopathy).
• To identify key complications, effective treatments, and survival rates in ALF patients.
• To explore emerging treatment options like liver transplantation.

Main Methods:

• Retrospective analysis of 620 ALF patients treated between 1973 and June 1985.
• Documentation of primary etiologies, common complications, and interventions.
• Evaluation of treatment outcomes and survival data.

Main Results:

• Paracetamol-induced necrosis, viral hepatitis, halothane hepatitis, and drug reactions were principal causes.
• Cerebral edema (treated with mannitol) and renal failure (managed with hemodialysis) were major concerns.
• Survival rates varied: 47-60% for paracetamol/viral hepatitis A/B, but only ~15% for non-A/non-B hepatitis and drug-induced ALF.

Conclusions:

• Effective management of ALF requires addressing cerebral edema, renal failure, electrolyte imbalances, and hemodynamic instability.
• Charcoal hemoperfusion showed promise in improving survival, particularly in early stages of encephalopathy.
• Liver transplantation is a critical consideration for ALF patients with poor prognosis, especially those with drug- or non-A/non-B hepatitis-induced failure.
