Definitions

Acute Liver Failure

Evidence of coagulation abnormality (INR ≥1.5) and any degree of alteration in mental status in the absence of pre exisiting chronic liver disease, cirrhosis and any illness of <26 weeks duration is defined as acute liver failure.[1][2] Few exceptions that are included in spite of their presentation with cirrhosis are Wilson disease, vertically-acquired HBV, and autoimmune hepatitis if they have been recognized for <26 weeks. When the above presentation duration is up to 26 weeks, acute liver failure is the better terminology to be used when compared to terms like fulminant hepatic failure, fulminant hepatitis or necrosis, hyperacute, acute and subacute liver failure.

Hepatic Encephalopathy

Based on their clinical manifestation, different grades of hepatic encephalopathy are defined as follows[3]

Grades Clinical Features
I Changes in behavior, minimal changes in level of consciousness
II Inappropriate behavior, gross disorientation, drowsiness, possibly asterixis
III Marked confusion, incoherent speech, mostly sleeping but arousable to vocal stimuli
IV Comatose, unresponsive to pain, decorticate or decerebrate posturing
