We investigated the anti-inflammatory effects of 3α-hydroxy-lup-20(29)-en-23, 28-dioic acid (HLEDA)-a lupane-type triterpene isolated from leaves of Acanthopanax gracilistylus W. W.Smith (AGS), as well as the underlying molecular mechanisms in lipopolysaccharide (LPS)-induced RAW264.7 cells. Our results demonstrated that HLEDA concentration-dependently reduced the production of nitric oxide (NO), significantly suppressed LPS-induced expression of TNF-α and IL-1β at the mRNA and protein levels in RAW264...

BACKGROUND: The outcome of medical treatment is worse in fulminant liver failure (FLF) developing on acute or chronic ground. Recently, liver transplantations with the use of living and cadaveric donors have been performed in these diseases and good results obtained. In this study, we aimed to present the factors affecting the recovery of cerebral functions after liver transplantation in hepatic encephalopathy (HE) developing in FLF, to identify irreversible patient groups and to prevent unnecessary liver transplantation...

Background: Fulminant form of hepatitis B related acute liver failure (FHB-ALF) is a rare but highly fatal outcome of acute hepatitis B virus (HBV) infection. Its related host factors have not been studied. Methods.: To identify functionally relevant biological pathway(s) in FHB-ALF pathogenesis, pathway enrichment analysis was conducted on a dataset of rare case-specific variants derived from exomic sequencing of ten unrelated cases. Key variants in identified pathways were validated using 312 HBV disease controls...

BACKGROUND: Infection with hepatitis B virus (HBV) can be symptomatic or asymptomatic. Apart from chronic HBV infection, the complications related to acute HBV infection are severe acute viral hepatitis and fulminant hepatitis characterised by liver failure. The optimal pharmacological treatment of acute HBV infection remains controversial. OBJECTIVES: To assess the benefits and harms of pharmacological interventions in the treatment of acute HBV infection through a network meta-analysis and to generate rankings of the available treatments according to their safety and efficacy...

Hepatitis E virus (HEV) is responsible for more than 50% of acute viral hepatitis cases in endemic countries. Approximately 2 billion individuals live in hepatitis E-endemic areas and, therefore, are at risk of infection. According to World Health Organization, HEV causes about 20.1 million infections and 70 000 deaths every year. In developing countries with poor sanitation, this disease is transmitted through contaminated water and is associated with large outbreaks, affecting hundreds or thousands of people...

We report a rare case of acute liver failure from acute hepatitis E virus (HEV) in a non-pregnant woman without comorbidities who survived after liver transplantation. The source was likely consumption of partially cooked pig liver. HEV genotype 3 is the second most common genotype causing acute hepatitis E in developed countries. Fulminant hepatitis E rarely occurs without a risk factor, as in our patient. Vigilant monitoring for chronic hepatitis E in post-transplant immunocompromised patients is needed.

BACKGROUND: Autoimmune hepatitis (AIH) is a rare and chronic inflammatory disorder associated with extrahepatic autoimmune diseases, including, infrequently, multiple sclerosis (MS). Short Reports: We report five cases of MS and AIH association. One patient developed AIH while under interferon beta-1b and the remaining while off disease-modifying therapy, although after methylprednisolone bolus in three. All presented a liver biopsy compatible with AIH. Hepatitis resolution was achieved with immunosuppressive treatment, but one patient died after a fulminant hepatitis requiring liver transplant...

Although chronic hepatitis C is still the leading indication for liver transplantation (LT) in the United States and Europe, acute liver failure caused by to hepatitis C is distinctly uncommon and transplantation for fulminant hepatitis C virus (HCV) has not been documented in the United States. We present a case report of fulminant hepatic failure caused by genotype 2a/c HCV not only treated with LT, but also complicated by severe, rapid recurrence of HCV within 6 days of transplantation. The risk factor for the infection was likely sexual, as there were no other concomitant causes of liver disease pre-transplant or explanations for acute hepatitis post-transplant...

A 20-year-old woman presented with acute exacerbation of ulcerative colitis. After treatment with infliximab, she developed a fulminant liver failure. Under supportive therapy and steroid medication, recovery of symptoms and transaminases occurred. A few case reports about hepatic side effects of anti-TNF-α antibodies in patients with inflammatory bowel disease have been published. These side effects ranged from asymptomatic increase of transaminases to fulminant liver failure necessitating transplantation...

Toll-like Receptor 9 (TLR9) is an innate immune receptor recognizing microbial DNA. TLR9 is also activated by self-derived DNA, such as mitochondrial DNA, in a variety of inflammatory diseases. We show here that TLR9 activation in vivo is controlled by an anti-TLR9 monoclonal Ab (mAb). A newly established mAb, named NaR9, clearly detects endogenous TLR9 expressed in primary immune cells. The mAb inhibited TLR9-dependent cytokine production in vitro by bone marrow-derived macrophages and conventional dendritic cells...

The energy sensor AMP-activated protein kinase (AMPK) is crucial for energy homeostasis. Recent studies have revealed that AMPK is involved in various energy-intensive pathological processes such as inflammation and apoptosis. The physiological functions of hepatic AMPK have been well studied, but the pathological significance of AMPK in liver disorders remains largely unknown. In the present study, the phosphorylation status and the roles of AMPK were investigated in mice with lipopolysaccharide (LPS)/d-galactosamine (D-Gal)-induced fulminant hepatitis...

Hemophagocytic lymphohistiocytosis is a rare immunologic disorder affecting small children. It is characterized by an excessive and injurious immune response which turns rapidly fatal unless promptly and effectively treated. The main clinical signs are prolonged fever, hepatosplenomegaly, bleeding and laboratory findings of pancytopenia, increased serum transaminases, hypertriglyceridemia and hypofibrinogenemia. Four genes responsible for familiar hemophagocytic lymphohistiocytosis, which is inherited in autosomal recessive manner, have been identified so far...

BACKGROUND: Acute pancreatitis (AP) in patients with fulminant viral hepatitis is well recognized and its mortality depends on the severity of hepatitis rather than pancreatitis. Acute pancreatitis associated with non-fulminant acute hepatitis A (AHA) has been rarely described, and is considered to have a benign course with good response to conservative management. OBJECTIVE: To perform a systematic review of the frequency and prognosis of AP associated with fulminant or non-fulminant AHA...

Hepatic encephalopathy (HE) is a neuropsychiatric syndrome resulting from acute liver failure. Previously, we demonstrated hepatoprotective effects of genistein in D-galactosamine (D-GalN)-induced fulminant hepatic failure (FHF). In this study, we evaluated behavioural and neuroprotective effects of genistein in rat model of HE. HE was induced by intraperitonial administration of D-GalN (250 mg/kg BW) twice a week for 30 days Genistein was given as co-treatment through oral gavage daily at dose of 5 mg/kg BW...

BACKGROUND: Living donor liver transplantation is now an established technique for treating children with end-stage liver disease. Few data exist about liver transplantation for exclusively young infants, especially infants of <3 months of age. We report our single-center experience with 12 cases in which living donor liver transplantation (LT) was performed during the first 3 months of life and compare the results with those of older infants who underwent LT. All of the patients were treated at the National Center of Child Health and Development, Tokyo, Japan...

Stem cell-based therapies have potential for treatment of liver injury by contributing to regenerative responses, through functional tissue replacement or paracrine effects. The release of extracellular vesicles (EV) from cells has been implicated in intercellular communication, and may contribute to beneficial paracrine effects of stem cell-based therapies. Therapeutic effects of bone-marrow derived mesenchymal stem cells (MSC) and vesicles released by these cells were examined in a lethal murine model of hepatic failure induced by d-galactosamine/tumor necrosis factor-α (TNF-α)...

Glycyrrhetinic acid (GA), the main active ingredient of licorice, reportedly has anti-inflammatory and hepatoprotective properties, but its molecular mechanisms remain be elusive. In the present study, Balb/c mice were pretreated with GA (10, 30, or 100mg/kg) 1h before lipopolysaccharide (LPS)/d-galactosamine (D-GalN) administration. In other in vitro experiment, RAW264.7 macrophages were pretreated with GA before LPS exposure. The mortality, hepatic tissue histology, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed...

Many papers have reported on pregnancy and delivery after liver transplantation, but there have been no reports on pregnancy after ABO-incompatible liver transplantation. This paper reports the first successful pregnancy and delivery of a newborn after ABO-incompatible liver transplantation for fulminant hepatic failure. The patient was a 39-year-old female. She had an ABO-incompatible liver transplantation, donated from her husband, due to subacute fulminant hepatitis of unknown etiology. She was taking tacrolimus, methylprednisolone, and mizoribine orally for the maintenance of immunosuppression at the time of discharge...

Acetaminophen (APAP) overdose accounts for half of the cases of acute liver failure worldwide. We previously reported that 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...
