The prevalence and natural history of untreated isolated central perivenulitis in adult allograft livers

Alyssa M. Krasinskas, A. Jake Demetris, John J. Poterucha, Susan C. Abraham – 23 April 2008 – Central perivenulitis (CP) in the allograft liver can be associated with portal‐based acute cellular rejection and autoimmune hepatitis or can occur in isolation (isolated CP). Although several studies have demonstrated the significance of CP, the prevalence and natural history of untreated isolated CP have not been well studied. We examined 100 adult allograft liver recipients who had long‐term follow‐up, had routine protocol biopsies, and received no treatment for isolated CP.

A novel role for adiponectin in regulating the immune responses in chronic hepatitis C virus infection

Clovis Palmer, Taline Hampartzoumian, Andrew Lloyd, Amany Zekry – 21 April 2008 – Adipose tissue releases pro‐inflammatory and anti‐inflammatory mediators, including adiponectin, which elicit a broad range of metabolic and immunological effects. The study aim was to determine in subjects infected with chronic hepatitis C virus (HCV) the effects of total adiponectin and its high‐molecular‐weight (HMW) and low‐molecular‐weight isoforms on HCV‐specific immune responses. Serum levels of total adiponectin and its isoforms were determined by immunoassay.

Defective hepatitis B virus DNA is not associated with disease status but is reduced by polymerase mutations associated with drug resistance

Scott Preiss, Margaret Littlejohn, Peter Angus, Alex Thompson, Paul Desmond, Sharon R. Lewin, Joe Sasadeusz, Gail Matthews, Gregory J. Dore, Tim Shaw, Vitini Sozzi, Lilly Yuen, George Lau, Anna Ayres, Chloe Thio, Anchalee Avihingsanon, Kiat Ruxrungtham, Stephen Locarnini, Peter A. Revill – 21 April 2008 – Defective hepatitis B virus DNA (dDNA) is reverse‐transcribed from spliced hepatitis B virus (HBV) pregenomic messenger RNA (pgRNA) and has been identified in patients with chronic HBV (CH‐B).

Nuclear receptor cofactor receptor interacting protein 140 controls hepatic triglyceride metabolism during wasting in mice

Mauricio Berriel Diaz, Anja Krones‐Herzig, Dagmar Metzger, Anja Ziegler, Alexandros Vegiopoulos, Martin Klingenspor, Karin Müller‐Decker, Stephan Herzig – 18 April 2008 – In mammals, triglycerides (TG) represent the most concentrated form of energy. Aberrant TG storage and availability are intimately linked to the negative energy balance under severe clinical conditions, such as starvation, sepsis, or cancer cachexia. Despite its crucial role for energy homeostasis, molecular key determinants of TG metabolism remain enigmatic.

Selection of high‐avidity CD8 T cells correlates with control of hepatitis C virus infection

Bérangère Neveu, Emilie Debeaupuis, Klara Echasserieau, Béatrice le Moullac‐Vaidye, Michelle Gassin, Loïg Jegou, Jérémie Decalf, Matthew Albert, Nicolas Ferry, Jérôme Gournay, Elisabeth Houssaint, Marc Bonneville, Xavier Saulquin – 18 April 2008 – Both strong antigenic avidity and acquisition of proper effector functions contribute to the efficacy of antiviral T cell responses.

Accuracy and reproducibility of transient elastography for the diagnosis of fibrosis in pediatric nonalcoholic steatohepatitis

Valerio Nobili, Francesco Vizzutti, Umberto Arena, Juan G. Abraldes, Fabio Marra, Andrea Pietrobattista, Rodolfo Fruhwirth, Matilde Marcellini, Massimo Pinzani – 18 April 2008 – Transient elastography (TE) has received increasing attention as a means to evaluate disease progression in chronic liver disease patients. In this study, we assessed the value of TE for the prediction of fibrosis stage in a cohort of pediatric patients with nonalcoholic steatohepatitis. Furthermore, TE interobserver agreement was evaluated.
