Overview
Acute liver failure is classified into three subcategories; hyperacute , acute, and subacute depending upon the time lapsed between the appearance of jaundice, to the development of encephalopathy. In can also be classified into fulminant and subfulminant based upon the time that has lapsed from the start if illness to the onset of encephalopathy.
Classification
The 1993 classification defines [1] It reflects the fact that the pace of disease evolution strongly influence prognosis. Underlying aetiology is the other significant determinant of outcome.[2] It is based upon the duration between onset of jaundice to onset of encephalopathy.
| Time | Classification |
|---|---|
| 1 week | Hyperacute |
| 1 week - 1 month | Acute |
| 1 week - 3 months | Subacute |
Acute liver failure can be classified into fulminant or subfulminant. Both the forms have poor prognosis. It is based upon the duration between onset of hepatic illness to development of encephalopathy.[3]
| Classification | Time for Hepatic Encephalopathy |
|---|---|
| Fulminant | within 2 months |
| Subfulminant | within 2 months to 6 months |
