Hepatitis E virus (HEV) causes self-limiting acute hepatitis in humans that can eventually result in acute liver failures or progress to chronic infections. While in tropical and sub-tropical areas, HEV infections are associated with important waterborne epidemics, in Northern countries, HEV infections are autochthonous with a zoonotic origin. In the past decade, it has become clear that certain HEV genotypes are zoonotic and that swine, and more generally Suidae, are the main reservoir. Zoonotic transmissions of the virus may occur via direct contact with infected pigs, wild boars or consumption of contaminated meat...

Background & Aims: San huang yin chi decoction(SHYCD) is derived from the yin chen hao decoction, a well-known and canonical Chinese medicine formula from the "Treatise on Febrile Diseases". Over the past decade, SHYCD has been used to treat and prevent the liver cirrhosis and liver failure. In the present study, we investigated the effects of SHYCD for acute on chronic liver failure(ACLF) and explored its potential mechanism. an ACLF rat model, which induced by carbon tetrachloride (CCl4) combined with D-galactosamine (D-GalN) and lipopolysaccharide(LPS), was used and confirmed by B-ultrasound analysis...

Drug induced liver injury is responsible for 50% of acute liver failure in developed countries. Ayurvedic and homeopathic medicine have been linked to liver injury. This case describes the first documented case of Punarnava mandur and Kanchnar guggulu causing drug induced liver injury. Drug induced liver injury may be difficult to diagnosis, but use of multi-modalities tools including the ACG algorithms, causative assessment scales, histological findings, and imaging, is recommended. Advanced imaging, such as magnetic resonance cholangiopancreatography, may possibly have a greater role than previously reported in literature...

BACKGROUND AND AIMS: Patients with cirrhosis frequently present with high serum ferritin and low transferrin concentrations, reflecting impaired liver function and inflammation. Recent studies have shown that transferrin and its saturation with iron are MELD-independent predictors of mortality in patients with acute on chronic liver failure or decompensated cirrhosis. The aim of this study was to evaluate the prognostic utility of serum iron parameters in relation to markers of liver function and immune activation...

Liver transplantation is the accepted treatment for patients with acute liver failure and liver-based metabolic disorders. However, donor organ shortage and lifelong need for immunosuppression are the main limitations to liver transplantation. In addition, loss of the native liver as target organ for future gene therapy for metabolic disorders limits the futuristic treatment options, resulting in the need for alternative therapeutic strategies. A potential alternative to liver transplantation is allogeneic hepatocyte transplantation...

Wilson's disease is a rare, inherited autosomal recessive disease of copper metabolism, in which the causative gene, ATP7B, results in absent or reduced function of the ATP7B transporter important for biliary excretion of copper and incorporation of copper into caeruloplasmin. Affected patients accumulate excessive copper within the liver, brain and other tissues. A disease mainly of children, adolescents and young adults; clinical features vary from the asymptomatic state to chronic liver disease, acute liver failure, and neuropsychiatric manifestations...

Mice deficient in the toll-like receptor (TLR) or the myeloid differentiation factor 88 (MyD88) are resistant to acute liver failure (ALF) with sudden death of hepatocytes. Chalcone derivatives from medicinal plants protect from hepatic damages including ALF, but their mechanisms remain to be clarified. Here, we focused on molecular basis of piperidylmethyloxychalcone (PMOC) in the treatment of TLR/MyD88-associated ALF. C57BL/6J mice were sensitized with D-galactosamine (GalN) and challenged with Escherichia coli lipopolysaccharide (LPS, TLR4 agonist) or oligodeoxynucleotide containing unmethylated CpG motif (CpG ODN, TLR9 agonist) for induction of ALF...

Immunotherapy with immune checkpoint inhibitors (ICIs) may be considered as a treatment option for various types of tumors, but the transplant recipient population as well as patients requiring long-term systemic immunosuppression for other reasons have been systematically excluded from clinical trials involving ICIs. We report a case of successful treatment with ICI in a liver transplant recipient diagnosed with a rare subtype of melanoma. This patient had not required any modification to her antirejection immunosuppression before or during immunotherapy, had not experienced any serious immune-related adverse event, and had a durable objective response for nearly 1...

Hepatotoxicity due to acetaminophen (APAP) overdose is a leading cause of drug-induced acute liver failure in clinic. Chlorogenic acid (CGA), a dietary polyphenol, was reported to prevent APAP-induced liver injury in our previous studies. This study aims to investigate the protection provided by CGA against APAP-induced hepatotoxicity via focusing on nuclear factor erythroid 2-related factor 2 (Nrf2) and extracellular regulated protein kinases (ERK)1/2. CGA prevented APAP-induced oxidative liver injury and enhanced Nrf2 activation in mice and in hepatocytes in vitro...

Due to the lack of adequate organs, the number of patients with end-stage liver diseases, acute liver failure or hepatic malignancies waiting for liver transplantation is constantly increasing. Accepting aged liver grafts is one of the strategies expanding the donor pool to ease the discrepancy between the growing demand and the limited supply of donor organs. However, recipients of organs from old donors may show an increased post-transplantation morbidity and mortality due to enhanced ischemia reperfusion injury...

BACKGROUND: N-acetylcysteine (NAC) has many uses in medicine; notable in the management of paracetamol toxicity, acute liver failure and liver surgery. The aim of this review was to critically appraise the published literature for the routine use of NAC in liver resection surgery. METHODS: An electronic search was performed of EBSCOhost (Medline and CINAHL database), PubMed and the Cochrane Library for the period 1990-2016. MeSH headings: 'acetyl-cysteine', 'liver resection' and 'hepatectomy' were used to identify all relevant articles published in English...

Natural antisense transcripts (asRNAs) that do not encode proteins are transcribed from rat, mouse, and human genes, encoding inducible nitric oxide synthase (iNOS), which catalyzes the production of the inflammatory mediator nitric oxide (NO). In septic shock, NO is excessively produced in hepatocytes and macrophages. The iNOS asRNA interacts with and stabilizes iNOS mRNA. We found that single-stranded 'sense' oligonucleotides corresponding to the iNOS mRNA sequence reduced iNOS mRNA levels by interfering with the mRNA-asRNA interactions in rat hepatocytes...

Neutrophils are the most abundant leukocyte in the human circulation. These short-lived cells are constantly produced from hematopoietic stem cells (HSC) within the bone marrow from which they daily reach the blood and perform major roles in innate immunity. Neutrophils are the first cells to reach inflamed tissues and are armed with a plethora of enzymes that help both with their trafficking within tissues and the killing of pathogens. Damaged or infected organs are rapidly invaded by neutrophils. Their erroneous activation within parenchyma or the vasculature is involved in the pathogenesis of several inflammatory diseases including arthritis, colitis, sepsis, acute lung injury and liver failure...

James Neuberger
Liver allocation policies determine how those livers that are offered for transplantation are allocated to those who have met the criteria for liver transplantation and are fit enough to undergo the procedure. The goals of allocation policies are based on varying combinations of need (reducing mortality awaiting a graft), benefit (maximising the outcomes of candidates on the list) or utility (maximising the life-years gained). Improvement in quality of life is rarely included in the setting of allocation policies...
