BACKGROUND/AIMS: Acute liver failure (ALF) is a rare but severe medical emergency. To date, there is no established treatment for non-acetaminophen-induced acute liver failure (NAI-ALF) other than liver transplantation, and little is known about the use of N-acetylcysteine (NAC) in NAI-ALF. A randomized case control study was conducted with the aim to determine the effect of NAC on the mortality of NAI-ALF patients, as well as to evaluate the safety and efficacy of NAC use. PATIENTS AND METHODS: A total of 80 patients diagnosed with NAI-ALF were included in the study...

Chemokine C-X-C ligand 16 (CXCL16), a single-pass Type I membrane protein belonging to the CXC chemokine family, is related to the inflammatory response in liver injury. In present study, we investigated the pathophysiological role of CXCL16, a unique membrane-bound chemokine, in acetaminophen (APAP)-induced hepatotoxicity in mice. Mice were injected with APAP, and blood and tissue samples were harvested at different time points. The serum high-mobility group box 1 and CXCL16 levels were quantified by sandwich immunoassays...

CONTEXT: Paracetamol (acetaminophen) poisoning is the most common cause of acute liver failure in the developed world. A paracetamol treatment nomogram has been used for over four decades to help determine whether patients will develop hepatotoxicity without acetylcysteine treatment, and thus indicates those needing treatment. Despite this, a small proportion of patients still develop hepatotoxicity. More accurate risk predictors would be useful to increase the early detection of patients with the potential to develop hepatotoxicity despite acetylcysteine treatment...

Acute liver failure (ALF) is a rare, but life-threatening disease that is characterized by the acute onset of jaundice, coagulopathy, and hepatic encephalopathy (HE) in patients without pre-existing liver disease. Main causes in Germany are drug toxicity, acetaminophen overdose, and viral hepatitis (A, B, E). For the initial assessment of patients with ALF and the diagnostic algorithm, the early detection of HE, exclusion of liver cirrhosis, immediate diagnosis of the underlying etiology, and evaluation for the necessity of liver transplantation (LT) are critical...

OBJECTIVES: Acute liver failure (ALF) is classically defined by coagulopathy and hepatic encephalopathy (HE); however, acute liver injury (ALI), i.e., severe acute hepatocyte necrosis without HE, has not been carefully defined nor studied. Our aim is to describe the clinical course of specifically defined ALI, including the risk and clinical predictors of poor outcomes, namely progression to ALF, the need for liver transplantation (LT) and death. METHODS: 386 subjects prospectively enrolled in the Acute Liver Failure Study Group registry between 1 September 2008 through 25 October 2013, met criteria for ALI: International Normalized Ratio (INR)≥2...

Paracetamol, also known as acetaminophen, is the most commonly used antipyretic and pain reliever and since 1955 it is available over-the-counter as a single formulation or in combination with other substances and, as indicated by the World Health Organization, it can be used in all the three steps of pain intensity. Paracetamol toxicity is one of the most common causes of poisoning worldwide. While paracetamol is described as relatively nontoxic when administered in therapeutic doses, it is known to cause toxicity when taken in a single or repeated high dose, or after chronic ingestion...

BACKGROUND & AIMS: Patients with acute liver failure (ALF) have defects in innate immune responses to microbes (immune paresis) and are susceptible to sepsis. Cytotoxic T-lymphocyte-associated protein 4 (CTLA4), which interacts with the membrane receptor B7 (also called CD80 and CD86), is a negative regulator of T-cell activation. We collected T cells from patients with ALF and investigated whether inhibitory signals down-regulate adaptive immune responses in patients with ALF. METHODS: We collected peripheral blood mononuclear cells from patients with ALF and controls from September 2013 through September 2015 (45 patients with ALF, 20 patients with acute-on-chronic liver failure, 15 patients with cirrhosis with no evidence of acute decompensation, 20 patients with septic shock but no cirrhosis or liver disease, and 20 healthy individuals)...

Acetaminophen (APAP) overdose is a leading cause of acute liver failure worldwide, in which mitochondrial DNA (mtDNA) released by damaged hepatocytes activates neutrophils through binding of Toll-like receptor 9 (TLR9), further aggravating liver injury. Here, we demonstrated that mtDNA/TLR9 also activates a negative feedback pathway through induction of microRNA-223 (miR-223) to limit neutrophil overactivation and liver injury. After injection of APAP in mice, levels of miR-223, the most abundant miRNAs in neutrophils, were highly elevated in neutrophils...

Extracorporeal liver support can be classified into cell-free, artificial methods (artificial liver support, ALS) and cell-based bioartificial methods (bioartificial liver support, BLS). ALS improves biochemical parameters of liver failure by the simultaneous removal of protein-bound and water-soluble substances. Here, the MARS therapy belongs to the most studied methods with a proved beneficial effect on hepatic encephalopathy (HE), hepatorenal syndrome (HRS) or hyperbilirubinemia. However, a general survival advantage of any liver support for liver failure has not been shown yet and is restricted to meta-analyses or patient subgroups...

Drug-induced liver injury (DILI) is the most common cause of acute liver failure in the Unites States and accounts for 10% of acute hepatitis cases. We report the only known case of diphenhydramine-induced acute liver injury in the absence of concomitant medications. A 28-year-old man with history of 13/14-chromosomal translocation presented with fevers, vomiting, and jaundice. Aspartate-aminotransferase and alanine-aminotransferase levels peaked above 20,000 IU/L and 5,000 IU/L, respectively. He developed coagulopathy but without altered mental status...

BACKGROUND: The recent outbreak of acute liver failure caused by herbal/dietary supplements (HDS) in Hawaii prompted evaluation of those patients who underwent emergency liver transplantation (LT) for HDS in the United States. METHODS: We queried the Scientific Registry of Transplant Recipients (2003-2015) to identify patients who underwent urgent LT for acute hepatic necrosis (AHN) and identified those with HDS use. This group of patients was then characterized...

Acetaminophen (APAP) overdose accounts for half of the cases of acute liver failure worldwide. We previously reported that Sestrin2 (Sesn2) protects against d-galactosamine/lipopolysaccharide-induced acute fulminant liver failure. In this study, we demonstrated that Sesn2 protects APAP-induced liver injury in mice, using a recombinant adenovirus encoding Sesn2 (Ad-Sesn2). First, we found that treatment of mice with toxic levels of APAP significantly reduced Sesn2 expression. Tail-vein injection with Ad-Sesn2 inhibited APAP-induced serum alanine aminotransferase and aspartate aminotransferase levels and markedly reduced hepatocyte degeneration and inflammatory cell infiltration...

BACKGROUND: Acetaminophen (APAP) is a conventional drug widely used in the clinic because of its antipyretic-analgesic effects. However, accidental or intentional APAP overdoses induce liver injury and even acute liver failure (ALF). Astaxanthin (ASX) is the strongest antioxidant in nature that shows preventive and therapeutic properties, such as ocular protection, anti-tumor, anti-diabetes, anti-inflammatory, and immunomodulatory effects. The aim of present study was to determine whether ASX pretreatment provides protection against APAP-induced liver failure...

We report here the successful treatment of hepatitis C virus (HCV) transmitted from a nucleic acid testing (NAT)-negative donor to three HCV-negative recipients-two renal transplants and one liver. Both renal recipients underwent standard deceased-donor renal transplantation with immediate graft function. The liver recipient underwent standard orthotopic liver transplantation and recovered uneventfully. The donor was a 39-year-old woman with a terminal serum creatinine of 0.7 mg/dL. She was high risk for bloodborne pathogens, based upon a history of sexual contact with an HCV-infected male partner...

Bacterial lipopolysaccharide (LPS)-induced acute liver failure (ALF) is a common severe clinical syndrome in intensive care unit. No other methods are available for its prevention apart from supportive treatment and liver transplantation. Tamoxifen (TAM) was reported to attenuate ALF induced by excessive acetaminophen, while its effect on LPS-induced ALF remained unknown. For this, in the present study, we comprehensively assessed whether TAM can attenuate ALF induced by LPS/galactosamine (GaIN). Mice were given TAM once a day for three times...

Acetaminophen (APAP) overdose is a common cause of acute liver failure, and beta-blockers are commonly used drugs in clinical practice. This study aimed to evaluate the effect of two different beta-blocker agents as nebivolol and atenolol against APAP-induced hepatotoxicity. Male Wistar rats were treated with APAP (2 g/kg/day, p.o.) to induce hepatotoxicity. Our results showed that nebivolol and atenolol reduced heart rate and blood pressure. Nebivolol (5 mg/kg/day, p.o.) for 14 days has a hepatoprotective effect shown by significant decrease in hepatic injury parameters (serum AST and ALT) with significant suppression of hepatic malondialdehyde (MDA) and nitric oxide (NO) which were elevated with APAP administration...

Acetaminophen is the leading cause of acute liver failure (ALF) in many countries including the United States. Hepatic glucuronidation by UDP-glucuronosyltransferase (UGT) 1A subfamily enzymes is the major route of acetaminophen elimination. Reduced glucuronidation may predispose some individuals to acetaminophen-induced ALF, but mechanisms underlying reduced glucuronidation are poorly understood. We hypothesized that specific microRNAs (miRNAs) may reduce UGT1A activity by direct effects on the UGT1A 3'-UTR shared by all UGT1A enzyme transcripts, or by indirect effects on transcription factors regulating UGT1A expression...

REVIEW
Eric Yoon, Arooj Babar, Moaz Choudhary, Matthew Kutner, Nikolaos Pyrsopoulos
Hepatic injury and subsequent hepatic failure due to both intentional and non-intentional overdose of acetaminophen (APAP) has affected patients for decades, and involves the cornerstone metabolic pathways which take place in the microsomes within hepatocytes. APAP hepatotoxicity remains a global issue; in the United States, in particular, it accounts for more than 50% of overdose-related acute liver failure and approximately 20% of the liver transplant cases. The pathophysiology, disease course and management of acute liver failure secondary to APAP toxicity remain to be precisely elucidated, and adverse patient outcomes with increased morbidity and mortality continue to occur...
