Effect of colesevelam on liver fat quantified by magnetic resonance in nonalcoholic steatohepatitis: A randomized controlled trial

Thuy‐Anh Le, Joshua Chen, Christopher Changchien, Michael R. Peterson, Yuko Kono, Heather Patton, Benjamin L. Cohen, David Brenner, Claude Sirlin, Rohit Loomba, for the San Diego Integrated NAFLD Research Consortium (SINC) – 20 March 2012 – Bile acid sequestrants (BAS) lower plasma low density lipoprotein levels and improve glycemic control. Colestimide, a BAS, has been claimed by computed tomography to reduce liver fat. Therefore, we examined the efficacy of colesevelam, a potent BAS, to decrease liver fat in patients with biopsy‐proven nonalcoholic steatohepatitis (NASH).

Hepatitis C virus infection enhances TNFα‐induced cell death via suppression of NF‐κB

Junseong Park, Wonseok Kang, Seung‐Wook Ryu, Woo‐Il Kim, Dong‐Yeop Chang, Dong Ho Lee, Do Youn Park, Youn‐Hee Choi, Kyungsun Choi, Eui‐Cheol Shin, Chulhee Choi – 20 March 2012 – Hepatitis C virus (HCV) infection results in liver injury and long‐term complications, such as liver cirrhosis and hepatocellular carcinoma. Liver injury in HCV infection is believed to be caused by host immune responses, not by viral cytopathic effects. Tumor necrosis factor‐alpha (TNF‐α) plays a pivotal role in the inflammatory processes of hepatitis C.

Transcriptomic analysis of the woodchuck model of chronic hepatitis B

Simon P. Fletcher, Daniel J. Chin, Yongmei Ji, A. Leonardo Iniguez, Bruce Taillon, David C. Swinney, Palanikumar Ravindran, Donavan T. Cheng, Hans Bitter, Uri Lopatin, Han Ma, Klaus Klumpp, Stephan Menne – 20 March 2012 – The Eastern woodchuck (Marmota monax) is naturally infected with woodchuck hepatitis virus (WHV), a hepadnavirus closely related to the human hepatitis B virus (HBV).

Impaired intrahepatic natural killer cell cytotoxic function in chronic hepatitis C virus infection

Stefania Varchetta, Dalila Mele, Stefania Mantovani, Barbara Oliviero, Eleonora Cremonesi, Serena Ludovisi, Giuseppe Michelone, Mario Alessiani, Riccardo Rosati, Marco Montorsi, Mario U. Mondelli – 20 March 2012 – Hepatitis C virus (HCV) persistence in the host results from inefficiencies of innate and adaptive immune responses. Most studies addressing the role of innate immunity concentrated on peripheral blood (PB) natural killer (NK) cells, whereas only limited information is available on intrahepatic (IH) NK cells.
