Brief Summary:
The purpose of this study is to collect clinical and epidemiological data as well as serum, plasma, urine, tissue and DNA samples on individuals who have acute liver failure and on individuals who have acute liver injury, a less severe group of patients who have coagulopathy but do not reach the threshold of encephalopathy.

Condition or disease
Acute Liver Failure Fulminant Hepatic Failure Acute Liver Injury

Detailed Description:

Although ALF is truly an orphan disease affecting only about 2,000 persons per year, its severity, its frequency among young adults, and its high resource utilization justifies the attention paid to it. In addition, ALF has captured the interest and attention of researchers because of its unique pathogenesis and extreme severity, encouraging us to understand the processes underlying all forms of liver injury, by focusing on this most lethal manifestation.

The etiologies associated with ALF have continued to change further over the years with an apparent decline in viral hepatitis, and a remarkable increase in acetaminophen toxicity to its current level of ~44-50% of cases. A further problem in studying ALF is that the number of cases of a specific etiology observed at any one institution are vanishingly small. The earliest goals of the ALF Study then were to more carefully define the etiologies of ALF on a national scale, and to finally allow in-depth study of specific ALF causes such as autoimmune ALF, viral hepatitis and Wilson disease (WD).

A second group of patients worthy of study are those with acute liver injury.It would be of value to study patients destined to possibly have ALF earlier in their illness for several reasons: first, we might be able to better predict who will progress to full liver failure; second, the current definition requiring encephalopathy limits the number of patients available for study at any site; finally, therapeutic trials might have greater efficacy if begun at earlier disease stages.

Patients who are enrolled are referred to ALFSG clinical sites by gastroenterologist/hepatologist and fellows. Detailed clinical data and bio-specimen (sera, urine, plasma, DNA and tissue if available) are collected. Subjects are followed long-term at 6 months and 12 months. Detailed clinical data and sera are collected.
