Recurrence of Hereditary Hemorrhagic Telangiectasia After Liver Transplantation: Clinical Implications and Physiopathological Insights

Jérôme Dumortier, Sophie Dupuis‐Girod, Pierre‐Jean Valette, Alexander Valent, Olivier Guillaud, Jean‐Christophe Saurin, Valérie Hervieu, Philip Robinson, Henri Plauchu, Pierre Paliard, Olivier Boillot, Jean‐Yves Scoazec – 14 December 2018 – Liver transplantation (LT) has been proposed as a curative treatment in hereditary hemorrhagic telangiectasia (HHT) with severe hepatic involvement. We provide a long‐term evaluation of graft status after LT for HHT, with a focus on the risk of recurrence.

Combatting Fibrosis: Exosome‐Based Therapies in the Regression of Liver Fibrosis

Li Chen, David A. Brenner, Tatiana Kisseleva – 13 December 2018 – Hepatic fibrosis results from chronic injury and inflammation in the liver and leads to cirrhosis, liver failure, and portal hypertension. Understanding the molecular mechanisms underlying hepatic fibrosis has advanced the prospect of developing therapies for regression of the disease.

Alpha‐Fetoprotein Decrease from > 1,000 to < 500 ng/mL in Patients with Hepatocellular Carcinoma Leads to Improved Posttransplant Outcomes

Neil Mehta, Jennifer L. Dodge, John P. Roberts, Ryutaro Hirose, Francis Y. Yao – 13 December 2018 – High alpha‐fetoprotein (AFP) > 1,000 ng/mL is associated with poor outcomes after liver transplantation (LT) for hepatocellular carcinoma (HCC). A new national policy has been implemented for AFP > 1,000 ng/mL requiring a decrease to < 500 ng/mL before LT, but there is a paucity of data on the optimal AFP threshold before LT.

Hedgehog Signaling Modulates Interleukin‐33‐Dependent Extrahepatic Bile Duct Cell Proliferation in Mice

Nataliya Razumilava, Junya Shiota, Nureen H. Mohamad Zaki, Ramon Ocadiz‐Ruiz, Christine M. Cieslak, Kais Zakharia, Benjamin L. Allen, Gregory J. Gores, Linda C. Samuelson, Juanita L. Merchant – 11 December 2018 – Hedgehog (HH) signaling participates in hepatobiliary repair after injury and is activated in patients with cholangiopathies. Cholangiopathies are associated with bile duct (BD) hyperplasia, including expansion of peribiliary glands, the niche for biliary progenitor cells.
