Hepatitis C in a French population‐based survey, 1994: Seroprevalence, frequency of viremia, genotype distribution, and risk factors

F Dubois, J Desenclos, N Mariotte, A Goudeau, The Collaborative Study Group – 30 December 2003 – The aims of this study were the following: (1) to estimate the prevalence of hepatitis C virus (HCV) antibody (anti‐HCV) in a population‐based survey of French residents not selected for risk factors; (2) to investigate the association between anti‐HCV seropositivity, viremia, the infecting HCV genotype, and the alanine transaminase (ALT) level; and (3) to identify risk factors for HCV infection by a nested case control study within this survey sample.

Survival after liver transplantation in cirrhotic patients with and without hepatocellular carcinoma: A comparative study

J Figueras, E Jaurrieta, C Valls, C Benasco, A Rafecas, X Xiol, J Fabregat, T Casanovas, J Torras, C Baliellas, L Ibanez, P Moreno, L Casais – 30 December 2003 – Cumulative recurrence after surgical resection for hepatocellular carcinoma (HCC) is very high. Several retrospective analyses have shown that liver transplantation was more effective than resection for patients with HCC at early tumor stages.

The low‐dose monoethylglycinexylidide test: Assessment of liver function with fewer side effects

C Reichel, A Nacke, T Sudhop, G Wienkoop, C Luers, C Hahn, C Pohl, U Spengler, T Sauerbruch – 30 December 2003 – The hepatic metabolism of lidocaine (1 mg/kg intravenously) to its metabolite monoethylglycinexylidide (MEG‐X) is the basis of the standard MEG‐X test. To reduce the lidocaine‐induced side effects, we evaluated the MEG‐X formation after 0.5 and 1 mg/kg lidocaine intravenously in subjects with normal (n = 5) and severely impaired liver function (n = 7) (study I).

The expression of endosomal rab proteins correlates with endocytic rate in rat liver cells

L K Juvet, T Berg, T Gjoen – 30 December 2003 – Hepatic endocytosis is characterized by a division of labor between the different cell types with respect to endocytosis, which is mediated by receptors expressed on their cell surface. We have investigated the expression of GTPases of the rab family in rat liver parenchymal and endothelial cells. Small GTPases of the rab protein family control distinct steps of intracellular transport both in the secretory and the endocytic pathway.

Regulation of cyclin‐dependent kinase inhibitor p21WAF1/Cip1/Sdi1 gene expression in hepatic regeneration

J H Albrecht, A H Meyer, M Y Hu – 30 December 2003 – WAF1/Cip1/Sdi1 (p21) is the prototype of a family of proteins that inhibit cyclin‐dependent kinases and regulate cell cycle progression in eukaryotic cells. In addition to normal cell cycle progression, p21 is involved in growth suppression mediated by p53 and transforming growth factor β (TGFβ), differentiation, and apoptosis. To gain insight into the possible involvement of p21 in liver cell growth, the expression and regulation of the p21 gene was evaluated in rodent models of liver regeneration and specimens of human liver diseases.

Autoimmune hepatitis in childhood: A 20‐year experience

G V Gregorio, B Portmann, F Reid, P T Donaldson, D G Doherty, M McCartney, A P Mowat, D Vergani, G Mieli‐Vergani – 30 December 2003 – To determine the clinical, biochemical, and histological features, and outcome of childhood autoimmune hepatitis (AIH), we reviewed the medical records of 52 children with AIH, 32 (median age: 10 [2‐15] years) anti‐nuclear and/or smooth muscle antibody (ANA/SMA) positive, 20 (7 [0.8‐14] years) liver/kidney microsomal antibody (LKM‐1) positive, with median follow‐up of 5 years (range 0.3‐19).

Ursodeoxycholic acid therapy in pediatric patients with progressive familial intrahepatic cholestasis

E Jacquemin, D Hermans, A Myara, D Habes, D Debray, M Hadchouel, E M Sokal, O Bernard – 30 December 2003 – Progressive familial intrahepatic cholestasis (PFIC) is a lethal inherited childhood cholestasis of hepatocellular origin. Different subtypes of PFIC have been described according to serum gamma‐glutamyl transpeptidase (GGT) activity. There is currently no effective medical therapy available for children with PFIC. We report on 39 patients with PFIC who received ursodeoxycholic acid (UDCA) orally (20‐30 mg/kg b.w./day) for a period of 2 to 4 years.

Treatment of chronic hepatitis C with interferon alfa‐n3: A multicenter, randomized, open‐label trial

D M Simon, S C Gordon, M M Kaplan, R S Koff, F Regenstein, G Everson, Y M Lee, F Weiner, A Silverman, T Plasse, D Fedorczyk, M Liao – 30 December 2003 – We studied the antiviral effectiveness and safety of interferon alfa‐n3, a natural alpha interferon which contains multiple interferon species, in the treatment of previously untreated patients with chronic hepatitis C. Seventy‐seven patients were randomized to receive either 1.0, 2.5, 5.0, or 10.0 million units (MU) of interferon alfa‐n3 three times a week for 24 weeks and were then followed for an additional 24 weeks.

Membrane potential of hepatic mitochondria after acute cocaine administration in rats—The role of mitochondrial reduced glutathione

A Masini, D Gallesi, F Giovannini, T Trenti, D Ceccarelli – 30 December 2003 – Cocaine hepatotoxicity may be mediated by oxidative damage, possibly involving mitochondrial injury. The effect of an acute dose of cocaine in rats on the mitochondrial level of reduced glutathione, nicotinamide adenine dinucleotide (NADH) and nicotinamide adenine dinucleotide phosphate (NADPH), important determinants in cellular defense against oxidative stress, was investigated.

Kupffer cells generate superoxide anions and modulate reperfusion injury in rat livers after cold preservation

H Shibuya, N Ohkohchi, K Seya, S Satomi – 30 December 2003 – This study was designed to determine the source of reactive oxygen species (ROS) and whether Kupffer cells modulate the injury of perfused rat liver after cold preservation. The livers of male Lewis rats pretreated with schizophyllan glucan (SPG) (10 mg/kg, SPG group) or gadolinium chloride (5 mg/kg; Gd group) and untreated rats (control group) were preserved in University of Wisconsin solution for 0, 12, and 24 hours at 4 degrees C and then perfused for 60 minutes with oxygenated Krebs‐Henseleit bicarbonate buffer.
