The incidence and clinical characteristics of chronic hepatitis in the elderly patient over age 61 were studied in 680 biopsied cases from 1978 to 1984. Twenty four cases of chronic hepatitis in the elderly (4% of the total cases and 8% of all chronic hepatitis patients) were detected; the incidence is much lower than liver cirrhosis. Most of these cases (96%) showed active hepatitis. They had a long-term history of liver damage and negative HBsAg and HBeAg tests. Sixty seven percent of the patients showed block formation of the liver surface and low K(ICG) values (an average of 0.12). Twenty three cases are in good performance status 3 years and 3 months following the diagnosis, but ten cases still show marked fluctuation of serum GOT and GPT activities (greater than 60 IU). K(ICG) values in 16 cases improved from 0.12 to 0.14 on average 3 years after the diagnosis, suggesting that these cases might not progress to liver cirrhosis at least in the near future.

An early detection of the progress to chronic stages of the acute diseases has particular pathogenic and therapeutic implications in hepatology. A complex clinical, biologic and morphologic study has been carried out in 86 patients with persistent acute hepatitis, recently released after 4-8 weeks of hospitalization for acute viral hepatitis, who were submitted to sequential investigations and follow up for a mean period of 16 months (range 2-24 months). All the patients have shown signs of activity of the liver injury, more than three months after the viral hepatitis onset (GOT/GPT 134 +/- 41 KU/219 +/- 59 KU, gammaglobulins 24.2 +/- 2.4%) and a characteristic immune pattern. In some cases, the morphologic investigations (endo-histologic and infrastructural) have revealed elements of acute and chronic active hepatitis. In 70% of the case the disease had a favourable course, while 30% of them showed a tendency to chronicization and even to cirrhosis, within a period of two years.

GOT and GPT activities were measured in percutaneous needle biopsy specimens of human liver tissue from 98 cases including normal subjects and patients with various liver diseases. Hepatic GOT activity was markedly decreased in liver tissue of patients with nonalcoholic liver cirrhosis. Hepatic GPT activity was markedly decreased in liver tissue of patients with alcoholic liver cirrhosis. The GOT/GPT ratio in liver tissue was increased in patients with alcoholic liver cirrhosis (5.32 +/- 2.03) and alcoholic liver disease (4.78 +/- 2.43). The increased SGOT/SGPT ratio in patients with alcoholic liver disease is due to primarily to the increased LGOT/LGPT ratio.

Subchronic treatment of male rats with carbon tetrachloride (CCl4, twice weekly 0.2 ml/kg p.o.) and feeding a 5% alcohol solution instead of drinking water led to a nearly complete liver cirrhosis in all animals within 4 weeks. This was also documented by a three fold increase in hepatic total hydroxyproline content. Steatosis was quantified by enhanced liver triglyceride concentrations and acute necroses by increments of serum enzyme activities (GPT, SDH). Daily oral treatment with malotilate (100 mg/kg) totally prevented the development of liver cirrhosis, hepatic hydroxyproline accumulation and increases in serum enzyme activities induced by CCl4-alcohol. In cianidanol-treated rats (100 mg/kg p.o.) only portoseptal fibrosis was seen, however hydroxyproline and triglyceride accumulation as well as enhanced serum enzyme activities were not suppressed. D-penicillamine (300 mg/kg p.o.) and colchicine (50 micrograms/kg i.p.) failed to protect rats against CCl4-alcohol induced fibrosis, necrosis and steatosis in this model.

Secretory immunoglobulin A (sIgA) in serum was measured in patients with various liver diseases using enzyme immunoassay specific to sIgA. Marked elevation of the serum sIgA concentrations was found in liver diseases especially in intrahepatic or extrahepatic cholestasis. In chronic hepatitis and liver cirrhosis serum sIgA correlated significantly with leucine aminopeptidase (r = 0.69), GOT (r = 0.66), alkaline phosphatase (r = 0.55), and direct bilirubin (r = 0.42). In acute hepatitis their levels correlated significantly with total bilirubin (r = 0.59) and GPT (r = 0.55). In acute hepatitis and acute exacerbation of chronic hepatitis the major peaks of serum sIgA were observed later than those of liver enzymes. These results suggest two mechanisms working to elevate the serum sIgA levels in liver diseases. In chronic hepatitis, liver cirrhosis, and intrahepatic and extrahepatic cholestasis the raised serum sIgA probably reflects reflux of bile, a rich source of secretory component and sIgA, into circulation. In acute or chronic massive liver necrosis elevation of sIgA may be associated with liver regeneration. Serial measurement of serum sIgA with other conventional parameters will contribute much to the understanding of the pathophysiology of liver diseases.

We assayed type III procollagen peptide in the sera of 213 patients with various liver diseases and 23 normal controls by radioimmunoassay. The non-cancerous limit of the serum level of type III procollagen peptide was defined as the mean +/- 2 SD of the patients with chronic hepatitis, liver cirrhosis and alcoholic liver disease; it was 50 ng/ml. The percentage of type III procollagen peptide in sera exceeding this limit was 22.2% in patients with hepatocellular carcinoma and 17.4% in metastatic liver cancer. Only patients with liver cirrhosis accompanied by alcoholic hepatitis exceeded this limit. In patients with hepatocellular carcinoma with peptide concentrations above 50 ng/ml, the serum level of GOT, GPT, LDH, T. Bil., LAP, gamma-GTP and T. Chol. was significantly higher than in patients with hepatocellular carcinoma whose serum peptide level was below 20 ng/ml.

Relationships between Normotest, prothrombin time, albumin, gamma-globulin, GPT, and the hepatic fractional clearance of 198Au-colloids as a measure of effective hepatic blood flow were studied by correlation analysis, in 50 patients with liver diseases, including chronic hepatitis or cirrhosis. Simple correlation coefficients were highly significant between Normotest, prothrombin time, albumin, and the hepatic fractional clearance; however, not between GPT or gamma-globulin and the other parameters. Further correlation analysis revealed a highly significant partial correlation coefficient between Normotest and albumin and the hepatic clearance; however, not between Normotest and albumin. As effective hepatic blood flow is considered to be proportional to the liver parenchymal volume, the above results indicate that vitamin-K-dependent clotting factors, as well as albumin, reflect the liver cell mass.

Assay conditions of human liver glutathione S-transferase and its activity in human serum from liver disease patients were investigated. One mmol/l reduced glutathione, and 1 mmol/l-1-chloro-2,4-dinitrobenzene, pH 6.5, were used for the measurement, because of the very low non-enzymatic conjugation. Glutathione S-transferase activity was inhibited by bilirubin, but this inhibition was counteracted by the presence of a low concentration of albumin. The normal human serum glutathione S-transferase activity was 5.2 +/- 2.4 I.U./l (mean +/- S.D.), and was not influenced by any differences of age, sex or leukocyte count. A significant increase in serum enzyme activity was noted in cases of acute hepatitis with GPT exceeding 200 I.U./l, primary hepatoma and metastatic liver cancer. Some of the cases with fulminant hepatitis showed extremely high values. The degree of correlation between serum glutathione S-transferase and GOT or GPT was high in acute hepatitis, with GOT or GPT exceeding 200 I.U./l, in fulminant hepatitis, primary hepatoma and gall stones, while in chronic hepatitis and liver cirrhosis it was low. In cases of acute hepatitis and fulminant hepatitis, the disappearance of serum glutathione S-transferase from the blood was much faster than that of GOT and GPT. Serum glutathione S-transferase measurements will provide new and unique information for the diagnosis of acute liver diseases.

The relationship between glutaraldehyde-treated polymeryzed human serum albumin (pHSA) and HBe antigen (HBeAg)-positive serum was examined by the use of a new enzyme-linked immunosorbent assay (ELISA). The author succeeded in measuring the pHSA binding activity (pHSA-BA) of HB surface antigen (HBsAg) particles in the present ELISA method using horseradish peroxidase-labelled pHSA after fixation of HBsAg on an anti-HBs-coated well of polystyrene microplates. In HBeAg-positive group, the pHSA-BA of sera of 40 asymptomatic carriers and 2 chronic persistent hepatitis (CPH) patients were higher than those of 8 chronic active hepatitis (CAH) (p less than 0.01) and 8 liver cirrhosis sera (p less than 0.05). On the contrary, in the anti-HBe-positive group the pHSA-BA of 17 asymptomatic carriers and 3 CPH sera were lower than those of 8 CAH (p less than 0.005) and 10 liver cirrhosis patient sera (p less than 0.005). In the both-negative group the pHSA-BA of 8 asymptomatic carrier and 3 CPH sera were also lower than that of 8 CAH (p less than 0.05). In acute exacerbation of HBsAg-positive CAH the pHSA-BA elevated one to two months before the peak of S-GPT level, being correlated with the DNA-polymerase activity. Because of its apparent reproducibility, it is concluded that low cost and some advantages may have clinical utility in the same setting as the HBeAg is now used.

Liver damage influenced by alcohol is already associated with the development of a portal hypertension at an early stage. With the aid of laparoscopic transhepatic manometry we determined the pressure levels in the branches of the portal and hepatic veins in 15 patients (16 examinations) comprising 14 men and 1 women, with alcoholic toxic liver damage. It was shown that already with alcoholic parenchymal damage associated with portal and centrolobular fibrosis, a portal hypertension is initiated, the greatest manifestation of which is found in the group with histological changes taking the form of a remodelling (distorsion of architecture) or cirrhosis. The level of alcohol consumption has no direct influence on the level of pressure in the vascular systems investigated. Ther is, however, a correlation between the level of alcohol consumption, extent of fibrosis and portal hypertension. For the clinico-chemical parameters investigated (Gamma-glob., GOT, GPT, GLDH, gamma-GT, alkaline phosphatase, bilirubin) no significant differences were found dependent on the level of alcohol consumption or the degree of fibrosis.
