Role of the coinhibitory receptor cytotoxic T lymphocyte antigen‐4 on apoptosis‐Prone CD8 T cells in persistent hepatitis B virus infection

Anna Schurich, Pooja Khanna, A. Ross Lopes, Ki Jun Han, Dimitra Peppa, Lorenzo Micco, Gaia Nebbia, Patrick T.F. Kennedy, Anna‐Maria Geretti, Geoffrey Dusheiko, Mala K. Maini – 25 February 2011 – An excess of coinhibitory signals has been proposed to drive the T‐cell exhaustion characteristic of persistent viral infections. In this study we examined the contribution of the coinhibitory receptor cytotoxic T lymphocyte antigen‐4 (CTLA‐4) to CD8 T cell tolerance in chronic hepatitis B virus (HBV) infection (CHB).

Significance of isolated hepatic veno‐occlusive disease/sinusoidal obstruction syndrome after liver transplantation

Mylène Sebagh, Daniel Azoulay, Bruno Roche, Emir Hoti, Vincent Karam, Elina Teicher, Laurence Bonhomme‐Faivre, Faouzi Saliba, Jean‐Charles Duclos‐Vallée, Didier Samuel – 23 February 2011 – After liver transplantation (LT), hepatic veno‐occlusive disease (VOD), which is also known as sinusoidal obstruction syndrome (SOS), has been reported initially in relation to azathioprine use and subsequently in relation to acute rejection (AR). Isolated veno‐occlusive disease (iVOD)/SOS raises some questions about its significance and especially its treatment.

Incidence of primary sclerosing cholangitis: A systematic review and meta‐analysis

Natalie A. Molodecky, Hashim Kareemi, Rohan Parab, Herman W. Barkema, Hude Quan, Robert P. Myers, Gilaad G. Kaplan – 23 February 2011 – Incidence studies of primary sclerosing cholangitis (PSC) are important for describing the disease's burden and for shedding light on the disease's etiology. The purposes of this study were to conduct a systematic review of the incidence studies of PSC with a meta‐analysis and to investigate possible geographic variations and temporal trends in the incidence of the disease.

Immune response to pandemic H1N1 2009 influenza a vaccination in pediatric liver transplant recipients

Wolfram Haller, Jim Buttery, Karen Laurie, Kathe Beyerle, Winita Hardikar, George Alex – 23 February 2011 – After the announcement of a worldwide pandemic in June 2009, a single dose of a monovalent pandemic H1N1 2009 influenza A (pH1N1/09) vaccine was advocated for all Australians who were 10 years and older because of excellent immunogenicity trial results for healthy children and adults. Immunocompromised patients have previously been shown to have lower seroconversion rates after routine vaccinations.
