Endotoxin and interleukin‐1 related hepatic inflammatory response promotes liver failure after partial hepatectomy

Marja A. Boermeester, Irene H. Straatsburg, Alexander P. J. Houdijk, Catharina Meyer, Wilma M. Frederiks, Robert I. C. Wesdorp, Cornelis J. F. van Noorden, Paul A. M. van Leeuwen – 1 November 1995 – Impairment of various functions of the liver and concomitantly increased levels of parameters of liver damage, a clinical entity termed liver failure, is commonly seen after partial hepatectomy. We investigated in a rat model whether damage of the remnant liver was due to local inflammatory responses, and related to endotoxin or interleukin‐1 (IL‐1).

An investigation of whether polymorphisms of cytochrome P4502E1 are genetic markers of susceptibility to alcoholic end‐stage organ damage in a chinese population

You‐Chen Chao, Tong‐Ho Young, Wei‐Kuo Chang, Hung‐Shang Tang, Chung‐Te Hsu – 1 November 1995 – The human cytochrome P4502E1 gene (P4502E1), coding for an ethanol‐inducible nitrosamine‐metabolizing P‐450, is involved in the metabolism of ethanol and many known carcinogens. Recently, restriction fragment length polymorphisms (RFLps) within the P4502E1 have been suggested as genetic markers of susceptibility to alcohol‐induced liver disease but the previous studies disagree whether alcoholics with c1 or c2 allele are more susceptible to alcohol‐induced liver disease.

Integration of hepatitis B virus and alteration of the 1p36 region found in cancerous tissue of primary hepatocellular carcinoma with viral replication evidenced only in noncancerous, cirrhotic tissue

Daniela Simon, Brian I. Carr – 1 November 1995 – We have studied the genetic profile of the host genome and hepatitis B virus (HBV) in HBV‐associated primary hepatocellular carcinoma (HCC). Comparative analyses of HCC cell line Hep 40 and the original biopsy specimens showed the episomal and replicating form of HBV only in the biopsy specimen from nontumor (NT) cirrhotic liver tissue, where a molecular change in the 1p36 region was detected (NT tissue showed a normal 46XY karyotype). In contrast, only integrated HBV was detected in HCC tumor (T) tissue and Hep 40 cells.

Inhibition of nitric oxide synthesis in the forearm arterial bed of patients with advanced cirrhosis

Bernard Campillo, Pierre‐Etienne Chabrier, Gabriel Pelle, Said Sediame, Guy Atlan, Paul Fouet, Serge Adnot – 1 November 1995 – Increased vascular production of nitric oxide (NO) may contribute to the peripheral vasodilation and hyperdynamic state complicating advanced liver cirrhosis.

T‐cell–mediated autologous hepatocytotoxicity in patients with chronic hepatitis C virus infection

Yun‐Fan Liaw, Ching‐Song Lee, Sun‐Lung Tsai, Bo‐Wen Liaw, Tse‐Ching Chen, I‐Shyan Sheen, Chia‐Ming Chu – 1 November 1995 – Virus‐specific cytotoxic T lymphocytes (CTLs) have been suggested to be responsible for the liver injuries in patients with hepatitis C virus (HCV) infection. However, there has been no report of direct evidence to substantiate this hypothesis. In this study, we performed in vitro autologous hepatocytotoxicity assay in 45 patients to examine a possible role of CTLs to HCV‐in‐fected liver cells.

Efficacy of interferon alfa therapy in chronic hepatitis C patients depends primarily on hepatitis C virus RNA level

Gotaro Yamada, Masahiro Takatani, Fumitoshi Kishi, Michiko Takahashi, Toshihiko Doi, Takao Tsuji, Sadahito Shin, Masashi Tanno, Mickey S. Urdea, Janice A. Kolberg – 1 November 1995 – To clarify the viral factors that may predict the therapeutic effect of interferon (IFN) in chronic hepatitis C (CHC) patients, we investigated the quantitative serum hepatitis C virus (HCV) RNA level, genotype, and liver biopsy histological features in 60 patients who were treated with 360 × 106 U of natural IFN‐α for 36 to 48 weeks and for more than 12 months after therapy.

Vascular adhesion molecule–1 and intercellular adhesion molecule–1 expression on rat liver cells after lipopolysaccharide administration in vivo

Marijke van Oosten, Erika van de Bilt, Helga E. de Vries, Theo J. C. van Berkel, Johan Kuiper – 1 November 1995 – During sepsis the infiltration of leukocytes plays a pivotal role in tissue damage. Induction of septic shock results in an early accumulation of polymorphonuclear leukocytes in the liver (after 3 hours), which is followed by an infiltration of mononuclear phagocytes (after 30 hours). Expression of adhesion molecules may contribute to the migration of leukocytes to the site of inflammation.

Transforming growth factorβ1 increases the number of apoptotic bodies and decreases intracellular pH in isolated periportal and perivenular rat hepatocytes

Antonio Benedetti, Antonio di Sario, Gianluca Svegliati Baroni, Anne Marie Jezequel – 1 November 1995 – Transforming growth factor beta 1 (TGFβ1) is involved in promoting cell death by apoptosis in the liver, whereas the activation of Na+/H+ exchanger has been related to cell proliferation. The aim of this study was to gain information on the effects of TGFβ1 on intracellular pH and Na+H+ exchange activity in isolated periportal (PP) and perivenular (PV) rat hepatocytes using the pH‐sensitive dye BCECF in a perfused subconfluent hepatocyte monolayer.

Specific targeting of adriamycin conjugates with monoclonal antibodies to hepatoma associated antigens to intrahepatic tumors in athymic mice

Ruth Adler, Esther Hurwitz, Jack R. Wands, Michael Sela, Daniel Shouval – 1 November 1995 – Doxorubicin (adriamycin), once considered the treatment of choice for hepatocellular carcinoma (HCC), is known to cause cardiotoxicity and myelotoxicity. To reduce the systemic toxicity of adriamycin by direct delivery of the drug to the tumor site, we established a panel of monoclonal antibodies (MAbs) to hepatoma associated antigens that were conjugated to adriamycin by a dextran bridge.

Primary sclerosing cholangitis in 32 children: Clinical, laboratory, and radiographic features, with survival analysis

Michael Wilschanski, Peter Chait, Judy A. Wade, Lori Davis, Mary Corey, Patrick St. Louis, Anne M. Griffiths, Laurence M. Blendis, Stanley P. Moroz, Linda Scully, Eve A. Roberts – 1 November 1995 – The clinical presentation and outcome of 32 children with primary sclerosing cholangitis (PSC) are reviewed, the largest North American series. The majority of patients were diagnosed in their second decade (median age: 13 years). Four children presented before the age of 2 years, but none in the neonatal period.
