Outcome and prognostic markers in severe drug‐induced liver disease

Einar Björnsson, Rolf Olsson – 15 July 2005 – The combination of high aminotransferases (hepatocellular injury) and jaundice has been reported to lead to a mortality rate of 10% to 50% for different drugs, a phenomenon known as “Hy's rule.” However, Hy's rule has never been validated, and limited data exist on predictors for outcome in hepatocellular and other forms of drug‐induced liver disease. All reports of suspected hepatic adverse drug reactions received by the Swedish Adverse Drug Reactions Advisory Committee (1970‐2004) were reviewed.

Treatment of advanced hepatitis C with a low accelerating dosage regimen of antiviral therapy

Gregory T. Everson, James Trotter, Lisa Forman, Marcelo Kugelmas, Arthur Halprin, Barbara Fey, Catherine Ray – 15 July 2005 – Patients with advanced hepatitis C virus (HCV) are at risk of death and are candidates for liver transplantation. After transplantation, HCV recurs and may rapidly progress to cirrhosis and graft loss. Treatment is needed to prevent progression of disease and minimize recurrence after liver transplantation.

Early response of α2(I) collagen to acetaldehyde in human hepatic stellate cells is TGF‐β independent

Gianluca Svegliati‐Baroni, Yutaka Inagaki, Ana‐Rosa Rincon‐Sanchez, Cindy Else, Stefania Saccomanno, Antonio Benedetti, Francesco Ramirez, Marcos Rojkind – 15 July 2005 – Acetaldehyde is fibrogenic and induces the expression of type I collagen genes in hepatic stellate cells. Some of these acetaldehyde‐dependent events are mediated by H2O2 and thus establish a direct connection between oxidative stress and collagen upregulation.

Antisense oligonucleotide reduction of DGAT2 expression improves hepatic steatosis and hyperlipidemia in obese mice

Xing Xian Yu, Susan F. Murray, Sanjay K. Pandey, Sheri L. Booten, Dingjiu Bao, Xiu‐Zhen Song, Susan Kelly, Songyuan Chen, Robert McKay, Brett P. Monia, Sanjay Bhanot – 6 July 2005 – In this study, we investigated the role of acyl‐coenzyme A:diacylglycerol acyltransferase 2 (DGAT2) in glucose and lipid metabolism in obese mice by reducing its expression in liver and fat with an optimized antisense oligonucleotide (ASO). High‐fat diet‐induced obese (DIO) C57BL/6J mice and ob/ob mice were treated with DGAT2 ASO, control ASO, or saline.

Intrahepatic gene expression profiles and alpha‐smooth muscle actin patterns in hepatitis C virus induced fibrosis

Daryl T.‐Y. Lau, Bruce A. Luxon, Shu‐Yuan Xiao, Michael R. Beard, Stanley M. Lemon – 28 June 2005 – To gain insight into pathogenic mechanisms underlying fibrosis in hepatitis C virus (HCV)‐mediated liver injury, we compared intrahepatic gene expression profiles in HCV‐infected patients at different stages of fibrosis and α‐smooth muscle actin (α‐SMA) staining patterns. We studied 21 liver biopsy specimens: 5 had no fibrosis (Ludwig‐Batts stage 0); 10 had early portal or periportal fibrosis (stages 1 and 2); and 6, advanced fibrosis (stages 3 and 4).
