Katherine James, Elisa Bertoja, James O'Beirne, Susan Mallett – 23 December 2009 – Budd‐Chiari syndrome (BCS) is the end result of a number of disease states resulting in hepatic venous outflow obstruction. We report a Janus kinase 2–homozygous patient with BCS who thrombosed a transjugular intrahepatic portosystemic shunt (TIPS) despite treatment with warfarin (international normalized ratio = 3.0), aspirin, and clopidogrel.

Allen, Eleanor Barnes, Michael Roggendorf, Hubert E. Blum, Robert Thimme – 23 December 2009 – Human leukocyte antigen B27 (HLA‐B27) is associated with protection in human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infection.

A. Janssen, Dominique Valla, European Network for Vascular Disorders of the Liver (EN‐Vie) – 23 December 2009 – Current recommendations for early anticoagulation in acute portal vein thrombosis unrelated to cirrhosis or malignancy are based on limited evidence.

Samantha DeLair, Thomas Hugh Feeley, Hyunjung Kim, Juan del Rio Martin, Leona Kim‐Schluger, Dianne LaPointe Rudow, Mark Orloff, Patricia A. Sheiner, Lewis Teperman – 23 December 2009 – The number of liver donors has not measurably increased since 2004 and has begun to decrease. Although many waitlisted patients may be suitable candidates to receive a living donor graft, they are often reticent to discuss living donation with close friends and family, partly because of a lack of knowledge about donor health and quality of life outcomes after donation.

Serena Chang, Karen Kodys, Gyongyi Szabo – 23 December 2009 – Hepatitis C virus (HCV) interferes with interferon (IFN)‐mediated innate immune defenses. Toll‐like receptor (TLR) 7 agonists robustly inhibit HCV infection. We hypothesize that HCV infection may interfere with the expression and/or function of TLR7, a sensor of single‐stranded RNA. We identified reduced TLR7 RNA and protein levels in hepatoma cells expressing HCV (full‐length, BB7‐subgenomic, and JFH‐1 clone) compared with control HCV‐naïve cells.

Baba, Guido Gerken, Ali Canbay – 23 December 2009 – Stress‐induced soluble major histocompatibility complex class I–related chains A/B (MIC A/B) are increased in chronic liver diseases and hepatocellular malignancy. We investigated the impact of these molecules on liver injury, apoptosis, and fibrosis in nonalcoholic steatohepatitis (NASH).
