Hepatitis E virus (HEV)‐specific T‐cell responses are associated with control of HEV infection

Pothakamuri Venkata Suneetha, Sven Pischke, Verena Schlaphoff, Jan Grabowski, Paraskevi Fytili, Anna Gronert, Birgit Bremer, Antoaneta Markova, Jerzy Jaroszewicz, Christoph Bara, Michael P. Manns, Markus Cornberg, Heiner Wedemeyer – 17 October 2011 – Hepatitis E virus (HEV) infection is usually self‐limited but may lead to acute hepatitis and rarely to fulminant hepatic failure. Persistent HEV infections have recently been described in organ transplant recipients receiving immunosuppressive medications, suggesting that HEV is controlled by adaptive immune responses.

Thrombocytopenia, splenomegaly, and portal blood flow in patients who have undergone liver transplantation for cirrhosis

Daniel Eyraud, Benjamin Granger, Christian Ionescu, Silvia Fratéa, Sabine Darnat, Jean‐Christophe Vaillant, Jean‐Michel Siksik, Laurent Hannoun, Pierre Coriat – 17 October 2011 – The platelet count (PC), the spleen size (SS), and the portal blood flow (PBF) have been independently studied in the perioperative period after orthotopic liver transplantation (OLT) for cirrhosis, but these parameters have not been described and analyzed in combination.

Accuracy and disagreement of computed tomography and magnetic resonance imaging for the diagnosis of small hepatocellular carcinoma and dysplastic nodules: Role of biopsy

Thomas Sersté, Vincent Barrau, Violaine Ozenne, Marie‐Pierre Vullierme, Pierre Bedossa, Olivier Farges, Dominique‐Charles Valla, Valérie Vilgrain, Valérie Paradis, Françoise Degos – 17 October 2011 – Liver macronodules, ranging from benign to low‐grade or high‐grade dysplastic nodules (LGDNs/HGDNs) and hepatocellular carcinoma (HCC), may develop during chronic liver diseases (CLDs).

A phase 2, randomized, double‐blind, placebo‐controlled study of GS‐9450 in subjects with nonalcoholic steatohepatitis

Vlad Ratziu, Muhammad Y. Sheikh, Arun J. Sanyal, Joseph K. Lim, Hari Conjeevaram, Naga Chalasani, Manal Abdelmalek, Anezi Bakken, Christophe Renou, Melissa Palmer, Robert A. Levine, B. Raj Bhandari, Melanie Cornpropst, Wei Liang, Benjamin King, Elsa Mondou, Franck S. Rousseau, John McHutchison, Mario Chojkier – 17 October 2011 – In nonalcoholic steatohepatitis (NASH), the extent of hepatocyte apoptosis correlates with disease severity. Reducing hepatocyte apoptosis with the selective caspase inhibitor GS‐9450 has a potential for altering the course of the liver disease.

Biochemical and immunologic effects of rituximab in patients with primary biliary cirrhosis and an incomplete response to ursodeoxycholic acid

Masanobu Tsuda, Yuki Moritoki, Zhe‐Xiong Lian, Weici Zhang, Katsunori Yoshida, Kanji Wakabayashi, Guo‐Xiang Yang, Toshio Nakatani, John Vierling, Keith Lindor, M. Eric Gershwin, Christopher L. Bowlus – 17 October 2011 – The aim of this study was to determine the safety and potential efficacy of B‐cell depletion with the anti‐CD20 monoclonal antibody rituximab in patients with primary biliary cirrhosis (PBC) and an incomplete response to ursodeoxycholic acid (UDCA).

Prospective biopsy‐controlled evaluation of cell death biomarkers for prediction of liver fibrosis and nonalcoholic steatohepatitis

Diana Joka, Kristin Wahl, Sarah Moeller, Jerome Schlue, Bernhard Vaske, Matthias J. Bahr, Michael P. Manns, Klaus Schulze‐Osthoff, Heike Bantel – 12 October 2011 – Fibrosis and steatosis are major histopathological alterations in chronic liver diseases. Despite various shortcomings, disease severity is generally determined by liver biopsy, emphasizing the need for simple noninvasive methods for assessing disease activity.

CD133+ liver tumor‐initiating cells promote tumor angiogenesis, growth, and self‐renewal through neurotensin/interleukin‐8/CXCL1 signaling

Kwan Ho Tang, Stephanie Ma, Terence K. Lee, Yuen Piu Chan, Pak Shing Kwan, Carol M. Tong, Irene O. Ng, Kwan Man, Ka‐Fai To, Paul B. Lai, Chung‐Mau Lo, Xin‐Yuan Guan, Kwok Wah Chan – 12 October 2011 – A novel theory in the field of tumor biology postulates that cancer growth is driven by a population of stem‐like cells, called tumor‐initiating cells (TICs). We previously identified a TIC population derived from hepatocellular carcinoma (HCC) that is characterized by membrane expression of CD133.
