Restoration of cerebral blood flow autoregulation and reactivity to carbon dioxide in acute liver failure by moderate hypothermia

Rajiv Jalan, Steven W. M. Olde Damink, Nicolaas E. P. Deutz, Peter C. Hayes, Alistair Lee – 30 December 2003 – In patients with acute liver failure (ALF) and uncontrolled intracranial hypertension, moderate hypothermia (32°C) reduces intracranial pressure (ICP) and cerebral blood flow (CBF), and can be used as a bridge to liver transplantation. The purpose of this study was to test the hypothesis that moderate hypothermia reduced ICP by restoring CBF autoregulation. Nine patients with uncontrolled intracranial hypertension and ALF who fulfilled the criteria for poor prognosis were studied.

A randomized 4‐arm multicenter study of interferon alfa–2b plus ribavirin in the treatment of patients with chronic hepatitis C not responding to interferon alone

Giorgio Saracco, Alessia Ciancio, Alda Olivero, Antonina Smedile, Luigi Roffi, Guido Croce, Cosimo Colletta, Giuseppe Cariti, Massimo Andreoni, Alberto Biglino, Guido Calleri, Giovanni Maggi, Gian Franco Tappero, Pier Giulio Orsi, Natalia Terreni, Antonio Macor, Angelo Di Napoli, Enrico Rinaldi, Giovannino Ciccone, Mario Rizzetto – 30 December 2003 – To determine whether a higher dosage of interferon (IFN) associated with ribavirin and/or prolonged time of administration may improve therapeutic efficacy, we conducted a 4‐arm randomized trial on patients with chronic hepatitis C not respondi

Initial amplification of duck hepatitis B virus covalently closed circular DNA after in vitro infection of embryonic duck hepatocytes is increased by cell cycle progression

Christelle Borel, Olivier Schorr, Isabelle Durand, Fabien Zoulim, Alan Kay, Christian Trepo, Olivier Hantz – 30 December 2003 – The relationship between the cell cycle and early amplification of duck hepatitis B virus covalently closed circular (CCC) DNA was studied after in vitro infection of fetal hepatocytes. We first showed that embryonic hepatocytes proliferated for at least 6 days after plating and that complete viral replication including CCC DNA amplification occurred in these proliferating cells.

Increased extracellular matrix remodeling is associated with tumor progression in human hepatocellular carcinomas

Nathalie Théret, Orlando Musso, Bruno Turlin, Dominique Lotrian, Paulette Bioulac‐Sage, Jean‐Pierre Campion, Karim Boudjéma, Bruno Clément – 30 December 2003 – Matrix metalloproteinase‐2 (MMP2) is a key enzyme in the process of extracellular matrix remodeling involved in tumor invasion and metastasis. The activation of MMP2 involves interplay with the membrane type‐matrix metalloproteinase‐1 (MT1‐MMP) and the tissue inhibitor of metalloproteinase‐2 (TIMP2). In vitro, activated hepatic stellate cells are a main source of MMP2 and collagen I induces MMP2 activation.

A potent antiviral effect on hepatitis C viral dynamics in serum and peripheral blood mononuclear cells during combination therapy with high‐dose daily interferon alfa plus ribavirin and intravenous twice‐daily treatment with interferon beta

Yasuhiro Asahina, Namiki Izumi, Masakatsu Uchihara, Osamu Noguchi, Kaoru Tsuchiya, Kosei Hamano, Nobuhiko Kanazawa, Jun Itakura, Shozo Miyake, Takahiro Sakai – 30 December 2003 – Hepatitis C virus (HCV) is known to infect and replicate within peripheral blood mononuclear cells (PBMC), thereby enabling the direct evaluation of antiviral mechanisms by analyzing HCV dynamics in PBMC.

Factors affecting liver fibrosis in human immunodeficiency virus–and hepatitis C virus–coinfected patients: Impact of protease inhibitor therapy

Yves Benhamou, Vincent Di Martino, Marie Bochet, Geneviève Colombet, Vincent Thibault, Amélie Liou, Christine Katlama, Thierry Poynard – 30 December 2003 – Hepatitis C virus (HCV)‐related liver fibrosis progression is accelerated in human immunodeficiency virus (HIV)‐infected patients. The effect of protease inhibitor (PI) therapy on liver fibrosis is unknown. The aim of this work was to analyze the impact of PI therapy on HCV‐related liver fibrosis in HIV/HCV coinfected patients.

Treatment strategy for small hepatocellular carcinoma: Comparison of long‐term results after percutaneous ethanol injection therapy and surgical resection

Junji Yamamoto, Shuichi Okada, Kazuaki Shimada, Takushi Okusaka, Susumu Yamasaki, Hideki Ueno, Tomoo Kosuge – 30 December 2003 – This comparative study was conducted to clarify the efficacy of percutaneous ethanol injection (PEI) and surgical resection in the treatment of small hepatocellular carcinomas (HCC). Thirty‐nine patients treated by PEI and 58 who underwent hepatic resection for small HCC (smaller than 3 cm and 3 or less in number) during the same period were enrolled. The surgery group included more patients with large and multiple bilobar nodules than the PEI group.

Intraductal papillary neoplasia of the liver associated with hepatolithiasis

Tse‐Ching Chen, Yasuni Nakanuma, Yoh Zen, Miin‐Fu Chen, Yi‐Yin Jan, Ta‐Sen Yeh, Cheng Tang Chiu, Tseng‐Tong Kuo, Jun‐ichi Kamiya, Koji Oda, Michinari Hamaguchi, Yoshiyuki Ohno, Ling‐Ling Hsieh, Yuji Nimura – 30 December 2003 – Intraductal papillary growth of neoplastic biliary epithelia with a fine fibrovascular stalk (intraductal papillary neoplasia of liver [IPN‐L]) resembling intraductal papillary mucinous neoplasm of pancreas is occasionally associated with hepatolithiasis.
