Psychosocial and behavioral factors in acetaminophen-related acute liver failure and liver injury

Acute liver failure including acetaminophen overdose.

Acute liver failure (ALF) is a dramatic, highly unpredictable clinical syndrome defined by the sudden onset of coagulopathy and encephalopathy. Acetaminophen overdose, the leading cause of ALF in the United States, has a 66% chance of recovery with early N-acetylcysteine treatment and supportive care. Cerebral edema and infectious complications are difficult to detect and treat in these patient...

LIVER FAILURE AND LIVER DISEASE LIVER FAILURE Acetaminophen-Induced Acute Liver Failure: Results of a United States Multicenter, Prospective Study

Severe acetaminophen hepatotoxicity frequently leads to acute liver failure (ALF). We determined the incidence, risk factors, and outcomes of acetaminophen-induced ALF at 22 tertiary care centers in the United States. Detailed prospective data were gathered on 662 consecutive patients over a 6-year period fulfilling standard criteria for ALF (coagulopathy and encephalopathy), from which 275 (42...

Chronic acetaminophen exposure in pediatric acute liver failure.

BACKGROUND Acetaminophen (N-acetyl-p-aminophenol [APAP]) is a widely used medication that can cause hepatotoxicity. We examined characteristics and outcomes of children with chronic exposure (CE) to APAP in the multinational Pediatric Acute Liver Failure (PALF) Study. METHODS A total of 895 children enrolled from 2002 to 2009 were grouped by APAP exposure history as: CE (received multiple dos...

Acetaminophen: Most common cause of acute liver failure in US

Acetaminophen-induced acute liver injury in HCV transgenic mice.

The exact etiology of clinical cases of acute liver failure is difficult to ascertain and it is likely that various co-morbidity factors play a role. For example, epidemiological evidence suggests that coexistent hepatitis C virus (HCV) infection increased the risk of acetaminophen-induced acute liver injury, and was associated with an increased risk of progression to acute liver failure. Howev...
