Synonyms and keywords: Liver failure; fulminating hepatic failure
Overview
Liver failure is the inability of the liver to perform its normal synthetic and metabolic function as part of normal physiology.
Historical Perspective
- The original definition of Acute liver failure by Trey and Davidson was in 1959.[1]
- In the late 1980s and early 1990s, more terminologies of Acute liver failure proposed in.[2][3]
- Term of Acute-on-chronic Liver failure suggested by Jalan and willimas in 2002.[4]
Classification
Three forms are recognized:
- Acute liver failure - development of hepatic encephalopathy (confusion, stupor and coma) and decreased production of proteins (such as albumin and blood clotting proteins) within four weeks of the first symptoms (such as jaundice) of a liver problem. "Hyperacute" liver failure is said to be present if this interval is 7 days or less, while "subacute" liver failure is said to be present if the interval is 5-12 weeks.[3]
- Chronic liver failure - usually occurs in the context of cirrhosis, itself potentially the result of many possible causes, such as excessive alcohol intake, hepatitis B or C, autoimmune, hereditary and metabolic causes (such as iron or copper overload or non-alcoholic fatty liver disease).Encephalopathy develops after 6 months.
- Acute on Chronic Liver Failure - when acute hepatic decompensation observed in patients with preexisting chronic liver disease characterized by one or more extrahepatic organ failures with a significantly increased risk of death.[5]
Pathophysiology
- The pathophysiology depends on the etiology of the Acute liver failure.
- Most cases of Acute liver failure (except acute fatty liver of pregnancy and Reye syndrome) will have massive hepatocyte necrosis and/or apoptosis leading to liver failure. Hepatocyte necrosis occurs due to ATP depletion causing cellular swelling and cell membrane disruption.
- The pathophysiology of cerebral edema and hepatic encephalopathy is seen in Acute Liver Failure is multi-factorial and includes altered blood-brain barrier secondary to inflammatory mediators leading to microglial activation, accumulation of glutamine secondary to ammonia crossing the BBB and subsequent oxidative stress leading to depletion of adenosine triphosphate (ATP) and guanosine triphosphate (GTP). This ultimately leads to astrocyte swelling and cerebral edema.
- Chronic liver failure is the result of Cirrhosis which is is an advanced stage of liver fibrosis that is accompanied by distortion of the hepatic vasculature.[6]

Cardiovascular disease
Autoimmune diseases
Malignant infiltration
Differential Diagnosis
Autoimmune hepatitis must be differentiated from other diseases that cause jaundice, nausea and vomiting, abdominal pain, arthragia, and hepatomegaly such as Hepatitis A,B,C, E, drug induced hepatitis, CMV hepatitis, EBV hepatitis, alcoholic hepatitis, Primary biliary cirrhosis and Primary sclerosing cholangitis.[7][8][9][10][11][12][13][14][15]

Epidemiology and Demographics
- Liver transplantation is the second most common solid organ transplantation, yet less than 10% of global transplantation needs are met at current rates.
- Chronic liver disease and cirrhosis are the 12(th) leading cause of death in the United States.[16]

The King's College criteria (KCC) may be used.
Contraindicated medications
Severe hepatic failure is considered an absolute contraindication to the use of the following medications:
- Carvedilol
- Conjugated estrogens/bazedoxifene
- Diclofenamide
- Dronedarone
- Nebivolol
- Rosuvastatin
- Simvastatin
- Spironolactone
- Sulfamethoxazole/Trimethoprim
- Doxorubicin Hydrochloride
- Tipranavir
The ALFSG index is a newer option that may be more accurate.[17]
