From the Guidelines
Decompensated liver failure requires immediate hospitalization and comprehensive management, focusing on identifying and addressing the underlying cause, supportive measures, and targeted interventions for specific complications, with liver transplantation evaluation initiated promptly for severe cases unresponsive to medical therapy, as recommended by the most recent guidelines 1.
Causes of Decompensated Liver Failure
The causes of decompensated liver failure include an excessive systemic inflammatory response triggered by precipitants such as proven microbial infection with sepsis, severe alcohol-related hepatitis, or other factors 1.
Management of Decompensated Liver Failure
Initial care focuses on:
- Identifying and addressing the underlying cause, such as stopping alcohol consumption, treating viral hepatitis, or discontinuing hepatotoxic medications
- Supportive measures, including:
- Fluid and electrolyte management
- Nutritional support with 1.2-1.5g/kg/day of protein
- Vitamin supplementation, particularly thiamine 100mg daily in alcoholic liver disease Specific complications require targeted interventions:
- Lactulose 25-30mL every 1-2 hours until bowel movement for hepatic encephalopathy, followed by 15-30mL 2-3 times daily
- Large-volume paracentesis with albumin (6-8g per liter removed) for ascites
- Prophylactic antibiotics like norfloxacin 400mg daily for spontaneous bacterial peritonitis prevention
- Endoscopic band ligation for bleeding varices with terlipressin 2mg IV every 4-6 hours or octreotide 50mcg bolus followed by 50mcg/hour infusion Renal dysfunction may require careful fluid management and potentially dialysis.
Liver Transplantation Evaluation
For severe cases unresponsive to medical therapy, liver transplantation evaluation should be initiated promptly, as it may be the only effective therapeutic option for selected patients with end-stage liver disease 1. The decision to proceed with liver transplantation should be made by a team of hepatologists in tertiary care centers equipped with a program of liver transplantation.
Key Considerations
The management of decompensated liver failure requires a comprehensive approach, taking into account the multisystem nature of the disease, and the potential for complications such as acute kidney injury, hepatopulmonary syndrome, and cirrhotic cardiomyopathy 1. Early identification and management of these complications are crucial to improving outcomes in patients with decompensated liver failure 1.
From the Research
Causes of Decompensated Liver Failure
- Decompensated liver cirrhosis can lead to various complications, including ascites, variceal bleeding, and hepatic encephalopathy 2, 3, 4
- Hepatic encephalopathy is a prognostically relevant neuropsychiatric syndrome that occurs in the course of acute or chronic liver disease, triggered by ammonia and inflammation 2
- Portal hypertension is central to the progression of liver disease and decompensation 5
- Malnutrition, frailty, and sarcopenia can lead to poorer outcomes in patients with decompensated liver disease 5
Management of Decompensated Liver Failure
- Initial management of hepatic encephalopathy focuses on supportive care and stabilization, including providing appropriate nutritional support 3
- Identifying and treating precipitating factors, such as infection or hemorrhage, is essential to improve the patient's prognosis 3, 4
- Therapeutic agents available for the management of hepatic encephalopathy include lactulose, rifaximin, and other treatments aimed at lowering the gut nitrogen load and serum ammonia level 2, 3, 6
- Non-selective beta blockers, such as carvedilol, can improve portal hypertension and may have a survival benefit 5
- Procedural techniques, such as shunt embolization, may be beneficial in refractory cases of hepatic encephalopathy 5
- Palliative care interventions can lead to improved quality of life and clinical outcomes in patients with decompensated liver disease 5
