Iron‐related markers are associated with infection after liver transplantation

Jennifer K. L. Chow, Tomas Ganz, Robin Ruthazer, Mary Ann Simpson, Elizabeth A. Pomfret, Fredric D. Gordon, Mark E. Westerman, David R. Snydman – 13 July 2017 – Though serum iron has been known to be associated with an increased risk of infection, hepcidin, the major regulator of iron metabolism, has never been systematically explored in this setting. Finding early biomarkers of infection, such as hepcidin, could help identify patients in whom early empiric antimicrobial therapy would be beneficial.

Increased ethanol‐inducible cytochrome P450‐2E1 and cytochrome P450 isoforms in exosomes of alcohol‐exposed rodents and patients with alcoholism through oxidative and endoplasmic reticulum stress

Young‐Eun Cho, Esteban Mezey, James P. Hardwick, Norman Salem, Dahn L. Clemens, Byoung‐Joon Song – 13 July 2017 – This study investigated the role of ethanol‐inducible cytochrome P450‐2E1 (CYP2E1) in enhancing CYP2E1 and other P450 proteins in extracellular vesicles (EVs) from alcohol‐exposed rodents and human patients with alcoholism and their effects on oxidative hepatocyte injury. Female Fischer rats and wild‐type or Cyp2e1‐null mice were exposed to three oral doses of binge ethanol or dextrose control at 12‐hour intervals.

Ribavirin suppresses hepatic lipogenesis through inosine monophosphate dehydrogenase inhibition: Involvement of adenosine monophosphate‐activated protein kinase‐related kinases and retinoid X receptor α

Shinya Satoh, Kyoko Mori, Daichi Onomura, Youki Ueda, Hiromichi Dansako, Masao Honda, Shuichi Kaneko, Masanori Ikeda, Nobuyuki Kato – 13 July 2017 – Ribavirin (RBV) has been widely used as an antiviral reagent, specifically for patients with chronic hepatitis C. We previously demonstrated that adenosine kinase, which monophosphorylates RBV into the metabolically active form, is a key determinant for RBV sensitivity against hepatitis C virus RNA replication. However, the precise mechanism of RBV action and whether RBV affects cellular metabolism remain unclear.

Expanding the Baveno VI criteria for the screening of varices in patients with compensated advanced chronic liver disease

Salvador Augustin, Mònica Pons, James B. Maurice, Christophe Bureau, Horia Stefanescu, Michel Ney, Hélène Blasco, Bogdan Procopet, Emmanuel Tsochatzis, Rachel H. Westbrook, Jaime Bosch, Annalisa Berzigotti, Juan G. Abraldes, Joan Genescà – 11 July 2017 – Patients with compensated advanced chronic liver disease (cACLD) can safely avoid screening endoscopy with a platelet count >150 × 109 cells/L and a liver stiffness measurement (LSM) <20 kPa (Baveno VI criteria). However, the total number of avoided endoscopies using this rule is relatively low.

The presence and severity of nonalcoholic steatohepatitis is associated with specific changes in circulating bile acids

Puneet Puri, Kalyani Daita, Andrew Joyce, Faridoddin Mirshahi, Prasanna K. Santhekadur, Sophie Cazanave, Velimir A Luketic, Mohammad S. Siddiqui, Sherry Boyett, Hae‐Ki Min, Divya P. Kumar, Rohit Kohli, Huiping Zhou, Phillip B. Hylemon, Melissa J. Contos, Michael Idowu, Arun J. Sanyal – 11 July 2017 – The histologic spectrum of nonalcoholic fatty liver disease (NAFLD) includes fatty liver (NAFL) and steatohepatitis (NASH), which can progress to cirrhosis in up to 20% of NASH patients. Bile acids (BA) are linked to the pathogenesis and therapy of NASH.

Ethanol‐induced steatosis involves impairment of lipophagy, associated with reduced Dynamin2 activity

Karuna Rasineni, Terrence M. Donohue, Paul G. Thomes, Li Yang, Dean J. Tuma, Mark A. McNiven, Carol A. Casey – 10 July 2017 – Lipid droplets (LDs), the organelles central to alcoholic steatosis, are broken down by lipophagy, a specialized form of autophagy. Here, we hypothesize that ethanol administration retards lipophagy by down‐regulating dynamin 2 (Dyn2), a protein that facilitates lysosome re‐formation, contributing to hepatocellular steatosis. Primary hepatocytes were isolated from male Wistar rats fed Lieber–DeCarli control or ethanol (EtOH) liquid diets for 6‐8 weeks.

Active immunization for prevention of De novo hepatitis B virus infection after adult living donor liver transplantation with a hepatitis B core antigen–positive graft

Shih‐Ho Wang, Poh‐Yen Loh, Ting‐Lung Lin, Li‐Man Lin, Wei‐Feng Li, Yu‐Hung Lin, Chih‐Che Lin, Chao‐Long Chen – 10 July 2017 – De novo hepatitis B virus (DNHB) infections may occur in recipients who do not receive prophylaxis after liver transplantation (LT) with antibody to hepatitis B core antigen (anti‐HBc)–positive donor grafts. Active immunization has been shown to prevent DNHB in pediatric recipients. Our aim is to investigate the efficacy of HBV vaccination for preventing DNHB in adult living donor liver transplantation (LDLT).
