Chantal Housset, Stanislas Pol, Françoise Carnot, Frédéric Dubois, Bertrand Nalpas, Bruno Housset, Pierre Berthelot, Christian Brechot – 1 April 1992 – To evaluate the factors determining the severity of chronic hepatitis B virus infection and the interactions of human immunodeficiency virus and hepatitis delta virus infections, we retrospectively analyzed 260 patients, 146 of whom were followed for a mean of 31.4 ± 1.8 mo.

Gavin M. Jonas, Timothy R. Morgan, Kengathevy Morgan, Inthirany Thillainadarajah, Cynthia Hornacek – 1 April 1992 – The atrial natriuretic peptide hormonal system is altered to a variable degree in patients with cirrhosis. Portal pressure and portal‐systemic shunting are also varied in cirrhosis. We used a portal vein–ligated rat model with predictable portal hypertension to study the effects of portal hypertension alone on the atrial natriuretic peptide hormonal system. Sham‐operated rats were used as controls.

Irene Virgolini, Christian Müller, Josef Höbart, Werner Scheithauer, Peter Angelberger, Helmar Bergmann, John O'Grady, Helmut Sinzinger – 1 April 1992 – Twelve patients with recently diagnosed acute viral hepatitis underwent serial 99mTc‐galactosyl neoglycoalbumin scanning of the liver (for up to 8 mo). Injection of 99mTc‐galactosyl neoglycoalbumin (150 mBq) at a rate of 3.5 mg (50 nmol; 1 ml) revealed that the liver is the exclusive site of tracer uptake.

Carla Colombo, Maria Rita Castellani, William F. Balistreri, Ettore Seregni, Maria Luisa Assaisso, Annamaria Giunta – 1 April 1992 – We have previously documented that ursodeoxycholic acid exerts a beneficial effect on liver function and bile acid metabolism in patients with cystic fibrosis. We hypothesized that the mechanism of action may be related in part to the choleretic properties of the administered bile acid.

Peter J. Scheuer, Parvin Ashrafzadeh, Sheila Sherlock, David Brown, Geoffrey M. Dusheiko – 1 April 1992 – To determine the histologic pattern of hepatitis C, 54 liver biopsy specimens from 45 patients with a clinicopathological diagnosis of hepatitis C were studied. All patients were seropositive for antibody to hepatitis C virus by second‐generation testing. Both transfusion‐related and sporadic cases were included. More than half the samples showed chronic hepatitis without cirrhosis, whereas 44% showed developing or fully established cirrhosis.

Sylvie Ricard‐Blum, Solange Bresson‐Hadni, Dominique‐Angèle Vuitton, Gerard Ville, Jean‐Alexis Grimaud – 1 April 1992 – Liver samples from patients with three different types of liver diseases, alveolar echinococcosis (a dense and irreversible fibrosis), hepatocellular carcinoma and alcoholic cirrhosis, were analyzed for their content in hydroxypyridinium cross‐links found in mature collagen. We demonstrated the presence of small amounts of pyridinoline in control livers (0.27 ± 0.06 pmol/pmol of collagen).

Silvia Fargion, Clara Mandelli, Alberto Piperno, Bruno Cesana, Anna L. Fracanzani, Mirella Fraquelli, Paolo A. Bianchi, Gemino Fiorelli, Dario Conte – 1 April 1992 – Two hundred twelve Italian patients with genetic hemochromatosis (181 men, mean age 50 ± 11 yr; and 31 women, mean age 49 ± 10 yr) were followed for a median period of 44 mo (range = 3 to 218 mo). Alcohol abuse was present in 31 subjects (15%), and chronic HBV and HCV infection were seen in 19 (9%) and 35 (24%) of 145 cases tested, respectively. Twenty‐four patients (11%) had concomitant p‐thalassemia trait.

Markus Meyer, Klaus Hermann Wiedorn, Peter Hans Hofschneider, Rajen Koshy, Wolfgang Helmut Caselmann – 1 April 1992 – Chronic hepatitis B virus infection is often associated with major structural rearrangements of both the integrated viral DNA and the associated cellular sequences. We present here the structure of a single‐copy hepatitis B virus insert cloned from human hepatocellular carcinoma DNA recently reported to encode a novel transcriptional trans‐activator function.
