Gennady P. Ilyin, Sophie Langouët, Maryvonne Rissel, Jean‐Guy Delcros, Andre Guillouzo, Christiane Guguen‐Guillouzo – 30 December 2003 – Ribavirin, a guanosine analog, used in combination with interferon α (IFN‐α) in the treatment of chronic hepatitis induced by hepatitis C virus (HCV) infection, has been shown to improve liver histology and to decrease transaminases even when administered alone. We analyzed the direct effects of ribavirin on the liver by using primary cultures of human and rat hepatocytes.

Herbert L. Bonkovsky, Maureen Poh‐Fitzpatrick, Neville Pimstone, Jorge Obando, Adrian Di Bisceglie, Christine Tattrie, Kristina Tortorelli, Paula LeClair, Mary G. Mercurio, Richard W. Lambrecht – 30 December 2003 – In some, but not all countries, porphyria cutanea tarda (PCT) has been associated with chronic infection with the hepatitis C virus (HCV). Recently, PCT has also been associated with mutations in the HFE gene that are associated with HLA‐linked hereditary hemochromatosis. Until now, few studies of these associations have been reported from North America.

Wenshi Gao, Rex C. Bentley, John F. Madden, Pierre‐Alain Clavien – 30 December 2003 – In livers excised for transplantation, sinusoidal endothelium appears especially vulnerable to injury during organ preservation in the cold and subsequent reperfusion. The degree of endothelial cell injury correlates with functional impairment of the graft following transplantation. The mechanism of injury remains obscure, but endothelial cell damage has been described as coagulative necrosis secondary to irreversible physico‐chemical damage.

Llovet, Jordi Bruix, Josep Fuster, Antoni Castells, Juan Carlos Garcia‐Valdecasas, Lluís Grande, Alex França, Concepció Brú, Miquel Navasa, Maria del Ayuso, Manel Solé, Maria Isabel Real, Ramon Vilana, Antoni Rimola, Josep Visa, Joan Rodés – 30 December 2003 – Tumoral recurrence rate and survival of patients with hepatocellular carcinoma (HCC) treated by orthotopic liver transplantation (OLT) depend on tumor stage.

Koichi Tsuneyama, Naoko Kono, Masahiro Hoso, Hiroyuki Sugahara, Kazuharu Yoshida, Kazuyoshi Katayanagi, M. Eric Gershwin, Katsuhiko Saito, Yasuni Nakanuma – 30 December 2003 – An autosomal recessive murine mutation, coined “aly/aly” or “alymphoplasia,” was recently reported. Homozygotes for aly are defective in both humoral and cell‐mediated immune function and have diffuse lymphoid cell infiltration of various tissues, particularly around the conduit ducts of the pancreas and salivary glands.

Wan‐Cheng Chow, Nathalie Boyer, Michele Pouteau, Corinne Castelnau, Michele Martinot‐Peignoux, Veronique Martins‐Amado, Francoise Degos, Crina Maghinici, Martine Sinegre, Jean‐Pierre Benhamou, Claude Degott, Serge Erlinger, Patrick Marcellin – 30 December 2003 – Treatment of patients with chronic hepatitis C has had limited success because of relapses and nonresponse to interferon alfa therapy (currently the only established therapeutic agent).

Qin Su, Claus H. Schröder, Walter J. Hofmann, Gerd Otto, Rudolf Pichlmayr, Peter Bannasch – 30 December 2003 – Transactivation of cellular genes and functional inactivation of p53 by the hepatitis B virus (HBV) X gene‐encoded protein (HBx) are proposed as alternative mechanisms for induction of hepatocellular carcinomas (HCCs) in chronic HBV infection. Using an immunohistochemical approach, we studied the expression of HBx in 39 explanted livers with HBV‐associated disease.
