The galactose elimination capacity, a measure of the functional liver cell mass, and liver volume were measured in 50 normal subjects of five different age groups (less than 50, 51 to 60, 61 to 70, 71 to 80 and greater than 81 years). The volume of the liver was evaluated by ultrasonography. All subjects had normal routine liver function tests and no(More)
Ultrasonography and upper gastrointestinal endoscopy were prospectively used to study 100 consecutive patients with liver cirrhosis. After a period of 20 months to 55 months, 21 patients had died, 23 were lost at follow-up, and 56 patients were reevaluated. In the patients who died during follow-up, the entry liver volume, measured by means of the hepatic(More)
The prognostic value of portal hemodynamics, measured by pulsed echo-Doppler, was prospectively evaluated, together with clinical, biochemical and endoscopic parameters, in a series of 50 consecutive patients with compensated cirrhosis. After a mean follow-up of 6 years, 25 patients had died, all from complications of liver disease. Among conventional(More)
A method is described to calculate liver volume at US using real-time equipment. The method is based on the measurement of the 3 maximum diameters of the liver. Equations were derived by correlation vs CT volume measurement using the 3 diameters (multiple regression) or their product (simple regression) as independent variables in 20 subjects with and(More)
Chronic infection with hepatitis C virus (HCV) is regarded as a risk factor for hepatocellular cancer, mostly in patients with liver cirrhosis. We looked for HCV genomes in the livers of patients with hepatocellular cancer who did not have cirrhosis to see whether HCV was directly oncogenic. Cancerous and non-cancerous liver tissue, and serum samples from(More)
BACKGROUND Contrasting data have so far been reported on the utility and efficacy of screening patients with cirrhosis for early detection of hepatocellular carcinoma (HCC). The goal of this study was to evaluate the efficacy of a regular ultrasonographic and laboratory follow-up for the early detection of small HCC, and to identify parameters correlated(More)
Direct immunofluorescence with an avidinbiotin system was used to investigate the expression of MHC molecules HLA-DR and HLA-A,B,C on bileducts in cryostat sections from 10 primary biliary cirrhosis (PBC) patients. Needle biopsy specimens from 55 patients with various chronic liver disorders, surgical biopsy specimens from 2 patients with recurrent(More)
In a randomized cross-over comparison, the effects of a mainly vegetable protein diet were compared with an animal protein diet in eight patients with cirrhosis and chronic permanent encephalopathy, under optimum lactulose therapy. After a run-in period, patients were fed two equi-caloric, equi-nitrogenous diets for 7 days (71 g total proteins), containing(More)
The effect of euglycemic hyperinsulinism on branched-chain amino acids (BCAA; valine, isoleucine and leucine) was evaluated in five obese subjects and five controls. A continuous intravenous insulin infusion raised plasma insulin to a steady-state level. An artificial endocrine pancrease that infused glucose was used to sustain euglycemia. Basal and(More)
It has been reported that myofibroblasts contain actin and that Ito cells are positive for desmin. The distribution of desmin and actin detected by immunofluorescence, of vitamin A autofluorescence and of Sudan III staining of lipid droplets has been evaluated in sequential stages of experimental liver fibrosis induced in rats by intraperitoneal injections(More)
