Hepatic ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and acute/chronic rejection as well as a key obstacle to expanding the donor pool in orthotopic liver transplantation (OLT). Although glucocorticoid receptor (GR) signaling may enhance cytoprotective programs, clinical use of glucocorticoid is limited due to adverse effects, while clinical relevance of GR-facilitated cytoprotection in OLT remains unknown. We aimed to evaluate the significance of hepatic GR in clinical OLT and verify the impact of recombinant human relaxin (rhRLX), which may function as GR agonist in tissue/disease-specific manner...

Both AMP-activated protein kinase (AMPK) agonist and inhibitor have been reported to protect against fulminant hepatitis, implying that AMPK may play a complicated role in the development of fulminant hepatitis. In this study, we exploited whether the novel AMPK agonist N6-(3-hydroxyphenyl)adenosine (named as M1) exerted protective effects on fulminant hepatitis and whether its beneficial effects were AMPK-dependent. Results showed that intraperitoneal injection of M1 improved liver function, ameliorated liver injury and finally raised the survival rate in D-galactosamine/lipopolysaccharide (GalN/LPS)-treated mice...

Stem cells derived from placental tissues are an attractive source of cells for regenerative medicine. Amniotic epithelial cells isolated from human amnion (hAECs) have desirable and competitive characteristics that make them stand out between other stem cells. They have the ability to differentiate toward all three germ layers, they are not tumorigenic and they have immunosuppressive properties. Although liver transplantation is the best way to treat acute and chronic hepatic failure patients, there are several obstacles...

The use of N-acetylcysteine is of unknown significance when it comes to acute liver failure of other origin but for paracetamol overdose. Current data state its beneficial use when added to standard treatment for acute alcoholic hepatitis, whereas this attitude is less clear for hepatitis of variable other origin. This review of literature attends to evaluate and reveal the possible interest of adding N-acetylcysteine to standard care of acute liver failure due to alcoholism or other non-paracetamol linked causes...

Alcoholic liver disease (ALD) comprises a clinical-histologic spectrum including fatty liver, alcoholic hepatitis (AH), and cirrhosis with its complications. Most patients are diagnosed at advanced stages and data on the prevalence and profile of patients with early disease are limited. Diagnosis of ALD requires documentation of chronic heavy alcohol use and exclusion of other causes of liver disease. Prolonged abstinence is the most effective strategy to prevent disease progression. AH presents with rapid onset or worsening of jaundice, and in severe cases may transition to acute on chronic liver failure when the risk for mortality, depending on the number of extra-hepatic organ failures, may be as high as 20-50% at 1 month...

Acute febrile illness is a common entity in tropics and often is challenging due a host of pathogenic bacteria, viruses and fungi. Extensive work up is required for better management. Rickettsiosis is uncommon and hence comes lower down in the differentials of multiorgan failure being superseded by the more common diseases as malaria, enteric fever and Dengue. We document a case of young male presenting with high grade fever, multiorgan dysfunction (hepatic, renal, neurological and respiratory involvement), conjunctival suffusion, retiform rash and without lymphadenopathy...

Dengue has a significant impact on the disease burden in the population residing in tropical countries. It is transmitted by the bite of Aedes mosquito. The virus have got some hepatotoxic effects. Most of the cases are asymptomatic. However, it should be considered as one of the causes of Acute Liver Failure in endemic countries. Our article focuses on the pathogenesis, manifestations, investigations and, the treatment options for dengue related hepatic dysfunction.

Overdose of acetaminophen (APAP) results in acute liver failure. We have investigated the role of a post-translational modification of proteins called O-GlcNAcylation, where the O-GlcNAc transferase (OGT) adds and O-GlcNAcase (OGA) removes a single β-D-N-acetylglucosamine (O-GlcNAc) moiety, in the pathogenesis of APAP-induced liver injury. Hepatocyte specific OGT knockout mice (OGT KO), which have reduced O-GlcNAcylation, and WT controls were treated with 300 mg/kg APAP and the development of injury was studied over a time course from 0-24 hr...

Autoimmune hepatitis (AIH) and type 1 diabetes mellitus (T1DM) are thought to be induced by autoimmunity, but their coexistence has rarely been reported. We herein report a case in which a patient with T1DM developed acute-onset AIH. A 26-year-old woman, who had been diagnosed with T1DM in childhood, was transferred to our hospital because of acute liver failure of unknown etiology. The administration of corticosteroids including steroid pulse therapy was effective. Based on the histological finding of massive centrilobular necrosis and a good response to steroid therapy, we diagnosed the patient with acute-onset AIH...

Objective Patients with acute hepatitis B sometimes develop acute liver failure (ALF), which has a poor prognosis. The efficacy of nucleoside analogue (NA) monotherapy for ALF due to transient hepatitis B virus infection (HBV-ALF) remains controversial. Further investigations are necessary in nations with a shortage of donor livers for liver transplantation. In the present study, we aimed to clarify the efficacy of combination therapy with corticosteroid (CS) and NA in the treatment HBV-ALF. Patients We examined the clinical and biochemical features of 19 patients with HBV-ALF who were treated in the early stage of the disease between 2000 and 2015...

BACKGROUND: Acute liver failure (ALF) is a life-threatening disease with a high mortality rate. However, there are limited treatments or devices available for ALF therapy. Here, we aimed to develop a new strategy for ALF treatment by transplanting functional liver organoids (LOs) generated from single donor-derived human induced pluripotent stem cell (hiPSC) endoderm, endothelial cells (ECs), and mesenchymal cells (MCs). METHODS: First, we isolated ECs and MCs from a single donor umbilical cord (UC) through enzyme digestion and characterized the UC-ECs and UC-MCs by flow cytometry...
