Steatosis: Co‐factor in other liver diseases

Elizabeth E. Powell, Julie R. Jonsson, Andrew D. Clouston – 16 June 2005 – The prevalence of fatty liver is rising in association with the global increase in obesity and type 2 diabetes. In the past, simple steatosis was regarded as benign, but the presence of another liver disease may provide a synergistic combination of steatosis, cellular adaptation, and oxidative damage that aggravates liver injury.

Oxidative mitochondrial DNA damage and deletion in hepatocytes of rejecting liver allografts in rats: Role of TNF‐α

Yuichi Nagakawa, George Melville Williams, Qizhi Zheng, Akihiko Tsuchida, Tatsuya Aoki, Robert A. Montgomery, Andrew S. Klein, Zhaoli Sun – 16 June 2005 – An orthotopic liver transplant model in the rat was used to evaluate the role of tumor necrosis factor alpha (TNF‐α) in liver transplant rejection. There were significantly increased levels of TNF‐α mRNA and parallel increases in 8‐hydroxy‐2′ deoxyguanosine (8‐OHdG) indicative of oxidative DNA damage present 7 to 12 days after transplantation.

A viral kinetic study using pegylated interferon alfa‐2b and/or lamivudine in patients with chronic hepatitis B/HBeAg negative

Vassiliki‐Anastasia Sypsa, Konstantinos Mimidis, Nicholas C. Tassopoulos, Dimitrios Chrysagis, Themistoklis Vassiliadis, Antonios Moulakakis, Maria Raptopoulou, Caterina Haida, Angelos Hatzakis – 16 June 2005 – We studied viral dynamic parameters in 44 chronic hepatitis B/hepatitis B e antigen (HBeAg)(−) patients treated with pegylated interferon alfa‐2b (PEG‐IFN) 100 or 200 μg weekly or lamivudine 100 mg daily or the combination of PEG‐IFN 100 or 200 μg with lamivudine.

Viral and host factors in early hepatitis C virus infection

James W. Mosley, Eva A. Operskalski, Leslie H. Tobler, William W. Andrews, Bruce Phelps, Janel Dockter, Cristina Giachetti, Michael P. Busch – 13 June 2005 – Since 1980, the Transfusion‐transmitted Viruses Study (TTVS) (1974–1980) has continued to maintain its computerized database and stored sera to enable ongoing study of new transfusion events since the 1970s. Most recently, we have used this resource to study parameters of acute hepatitis C virus (HCV) infection among 94 donor–recipient pairs in which there was transmission.

Characterization of small nodules in cirrhosis by assessment of vascularity: The problem of hypovascular hepatocellular carcinoma

Luigi Bolondi, Stefano Gaiani, Natascia Celli, Rita Golfieri, Walter Francesco Grigioni, Simona Leoni, Anna Maria Venturi, Fabio Piscaglia – 13 June 2005 – In a prospective study, we examined the impact of arterial hypervascularity, as established by the European Association for the Study of the Liver (EASL) recommendations, as a criterion for characterizing small (1‐3 cm) nodules in cirrhosis. A total of 72 nodules (1‐2 cm, n = 41; 2.1‐3 cm, n = 31) detected by ultrasonography in 59 patients with cirrhosis were included in the study.

Autoimmune hepatitis: Effect of symptoms and cirrhosis on natural history and outcome

Jordan J. Feld, Huong Dinh, Tamara Arenovich, Victoria A. Marcus, Ian R. Wanless, E. Jenny Heathcote – 13 June 2005 – Although the natural history of autoimmune hepatitis (AIH) has been characterized, little is known about patients who present asymptomatically. Consequently, whether they require immunosuppressive therapy with its associated complications is unclear. To compare the natural history of asymptomatic AIH with symptomatic AIH, a large cohort of patients from a single center was examined.
