Humoral immune response to the E2 protein of hepatitis G virus is associated with long‐term recovery from infection and reveals a high frequency of hepatitis G virus exposure among healthy blood donors

M Tacke, S Schmolke, V Schlueter, S Sauleda, J I Esteban, E Tanaka, K Kiyosawa, H J Alter, U Schmitt, G Hess, B Ofenloch‐Haehnle, A M Engel – 30 December 2003 – The second envelope protein (E2) of the hepatitis G virus (HGV) was expressed in Chinese hamster ovary (CHO) cells and showed a molecular weight of approximately 60 to 70 kd, with 15 to 25 kd of the size contributed by N‐linked glycosylation. An enzyme‐linked immunosorbent assay (ELISA) using HGV‐E2 was developed to test for antibodies to this protein (anti‐E2) in human sera.

A randomized, controlled trial of a 24‐month course of interferon alfa 2b in patients with chronic hepatitis B who had hepatitis B virus DNA without hepatitis B e antigen in serum

P Lampertico, E Del Ninno, A Manzin, M F Donato, M G Rumi, G Lunghi, A Morabito, M Clementi, M Colombo – 30 December 2003 – Short‐term interferon treatment of serum hepatitis B e antigen (HBeAg)‐negative carriers with serum hepatitis B virus (HBV) DNA and histological features of chronic hepatitis B has been largely unsuccessful. In a pilot study of long‐term treatment, 42 such patients were randomly assigned to 6 million units of interferon alfa 2b (IFN‐α2b) three times per week for 24 consecutive months (n = 21, 4 with cirrhosis) or to no therapy (n = 21, 3 with cirrhosis).

Nucleotide sequence variations in the internal ribosome entry site of hepatitis C virus‐1b: No association with efficacy of interferon therapy or serum HCV‐RNA levels

C Yamamoto, N Enomoto, M Kurosaki, S Yu, J Tazawa, N Izumi, F Marumo, C Sato – 30 December 2003 – The extreme 5′‐proximal sequences of the hepatitis C virus (HCV) genome including the 5′untranslated region (5′UTR) and the first 30 nucleotides of the core region are highly conserved, and serve as an internal ribosome entry site (IRES) that initiates the cap‐independent translation of HCV polyprotein. Mutations in the IRES sequence have been shown to cause changes in the efficiency of protein translation in vitro.

Factors associated with gallstone disease in the MICOL experience

A F Attili, R Capocaccia, N Carulli, D Festi, E Roda, L Barbara, L Capocaccia, A Menotti, L Okolicsanyi, G Ricci, L Lalloni, S Mariotti, C Sama, E Scafato – 30 December 2003 – The epidemiological associations of gallstone disease were evaluated in a general population sample of 29,584 individuals (15,910 men and 13,674 women; age range, 30‐39 years) belonging to 14 cohorts examined between December 1984 and April 1987.

Pathology of chronic hepatitis C in children

M Kage, T Fujisawa, K Shiraki, T Tanaka, T Fujisawa, A Kimura, K Shimamatsu, E Nakashima, M Kojiro, M Koike, Y Tazawa, D Abukawa, M Okaniwa, H Takita, A Matsui, T Hayashi, T Etou, S Terasawa, K Sugiyama, H Tajiri, A Yoden, Y Kajiwara, M Sata, Y Uchimura – 30 December 2003 – Limited information is available regarding the histology of hepatitis C virus infection in children. The aim of this study was to determine the histological pattern of chronic hepatitis C (CHC) in children, and liver biopsy specimens from 109 pediatric patients with CHC were examined.

Biochemical and virological outcome of patients with chronic hepatitis C treated with interferon alfa‐2b for 6 or 12 months: A 4‐year follow‐up of 211 patients

E K Manesis, C Papaioannou, A Gioustozi, G Kafiri, J Koskinas, S J Hadziyannis – 30 December 2003 – To compare two interferon (IFN) schedules for the treatment of chronic hepatitis C, we followed 211 patients who received 3 million units IFN‐α2b thrice weekly for either 6 months (group 1; 85 patients) or 12 months (group 2; 126 patients), with a median follow‐up of 3.4 (0.1‐ 8.4) and 4.2 (0.7‐8.7) years, respectively. The biochemical and virological responses at the end of treatment were 34.1% and 16.5% versus 62.7% and 41.2% for the 6‐ and the 12‐month regimens, respectively.

Transport of reduced glutathione in hepatic mitochondria and mitoplasts from ethanol‐treated rats: Effect of membrane physical properties and S‐adenosyl‐L‐methionine

A Colell, C Garcia‐Ruiz, A Morales, A Ballesta, M Ookhtens, J Rodes, N Kaplowitz, J C Fernandez‐Checa – 30 December 2003 – Ethanol intake depletes the mitochondrial pool of reduced glutathione (GSH) by impairing the transport of GSH from cytosol into mitochondria. S‐Adenosyl‐L‐methionine (SAM) supplementation of ethanol‐fed rats restores the mitochondrial pool of GSH. The purpose of the current study was to determine the effect of ethanol feeding on the kinetic parameters of mitochondrial GSH transport, the fluidity of mitochondria, and the effect of SAM on these changes.

Multivesicular stellate cells in primary biliary cirrhosis

R G Cameron, M G Neuman, L M Blendis – 30 December 2003 – Stellate cells have only recently received attention in patients with primary biliary cirrhosis (PBC). We used electron microscopy and morphometry to perform a qualitative and quantitative examination of lipid‐storing activity of stellate cells in liver biopsies of 26 patients with noncirrhotic and cirrhotic PBC. Parallel with this study, a comparative analysis of the morphology of stellate cells in 51 patients with livers of normal histology was performed.

Pre‐S2 defective hepatitis B virus infection in patients with fulminant hepatitis

T Pollicino, A R Zanetti, I Cacciola, M A Petit, A Smedile, S Campo, L Sagliocca, M Pasquali, E Tanzi, G Longo, G Raimondo – 30 December 2003 – Controversial data were recently published concerning the association of hepatitis B virus (HBV) variants with fulminant hepatitis (FH). In this study, we first analyzed the complete nucleotide sequences of HBV genomes isolated from serum samples from a surgeon and his mother, who was accidentally infected by the son; both died of FH.
