George K. K. Lau, Ming‐Liang He, Daniel Y. T. Fong, Angeline Bartholomeusz, Wing‐yan Au, Albert K. W. Lie, Stephen Locarnini, Raymond Liang – 30 December 2003 – Exacerbation of hepatitis B virus (HBV) is a serious cause of morbidity and mortality in hepatitis B surface antigen (HBsAg)‐positive patients undergoing transplantation. Our aim was to evaluate the effectiveness of lamivudine to prevent hepatitis due to exacerbation of HBV in HBsAg‐positive patients treated with allogeneic hematopoietic cell transplantation.

Béatrice Seignères, Christian Pichoud, Perrine Martin, Philip Furman, Christian Trépo, Fabien Zoulim – 30 December 2003 – To design combination strategies for chronic hepatitis B therapy, we evaluated in vitro the inhibitory activity of 4 nucleoside analogs, (−)FTC, L‐FMAU, DXG, and DAPD, in comparison with lamivudine (3TC) and PMEA.

Zeid Kayali, Victor E. Buckwold, Bridget Zimmerman, Warren N. Schmidt – 30 December 2003 – Approximately 40% of patients with chronic hepatitis C virus (HCV) infection develop detectable serum cryoglobulins or cryoprecipitates (CP), although most do not show clinical or physical signs of syndromic cryoglobulinemia. Although association of HCV with the extrahepatic complications of cryoglobulinemia is widely recognized, the relationship of cryoglobulinemia with liver disease is unclear.

Michael André Kern, Dominic Schubert, Dina Sahi, Mirja Mareike Schöneweiß, Ilona Moll, Anke Maria Haugg, Hans Peter Dienes, Kai Breuhahn, Peter Schirmacher – 30 December 2003 – Recent studies have shown increased levels of cyclooxygenase‐2 (COX‐2) in a variety of human malignancies, including hepatocellular carcinoma (HCC), but so far it is unknown whether COX‐2 contributes to the malignant growth and whether inhibition of COX‐2 function modifies the malignant potential of liver tumors.

Alberto Larghi, Massimo Zuin, Andrea Crosignani, Maria Lisa Ribero, Cristina Pipia, Pier Maria Battezzati, Giorgio Binelli, Francesco Donato, Alessandro Remo Zanetti, Mauro Podda, Alessandro Tagger – 30 December 2003 – We identified 15 patients with acute hepatitis C (AHC) among 29 healthy volunteers participating in 2 consecutive pharmacokinetics studies. Molecular techniques were used to determine the relatedness of viral strains, whereas clinical and virologic follow‐up was started to establish the course and outcome of the acute infection.

Friedman, Hisataka Moriwaki – 30 December 2003 – Acyclic retinoid, a synthetic retinoid analog, as well as interferon alfa (IFN‐α) and IFN‐β induce apoptosis in hepatocellular carcinoma (HCC) cells and are used clinically in the prevention of HCC.

Markus F. Wolschek, Christiane Thallinger, Malgorzata Kursa, Vanessa Rössler, Matthew Allen, Cornelia Lichtenberger, Ralf Kircheis, Trevor Lucas, Martin Willheim, Walter Reinisch, Alfred Gangl, Ernst Wagner, Burkhard Jansen – 30 December 2003 – Systemic tumor‐targeted gene delivery is attracting increasing attention as a promising alternative to conventional therapeutical strategies. To be considered as a viable option, however, the respective transgene has to be administered with high tumor specificity.
