Until now, the hepatitis B virus has been thought to play a minor role in the aetiology of chronic liver disease in Australia. This is a report of 21 patients with cirrhosis and/or primary hepatocellular carcinoma with hepatitis B antigenaemia. Primary hepatocellular carcinoma occurred in six patients, five of whom had underlying cirrhosis. The disease occurred mainly in non-Australian born males, and was not often associated with a previous history of hepatitis. The death of 16 patients within 12 months of presentation is in contrast to previous concepts of the benign nature of hepatitis B associated cirrhosis.

Family member of 13 patients with hepatitis B surface antigen (HBsAg) positive primary hepatocellular carcinoma (PHC) were tested for the presence of hepatitis B virus-associated antigens and antibodies. Of the 122 members examined, circulating HGsAg was detected in 47 (39%), antibody to HBsAg (anti-HBs) was found in 37 (30%), and antibody to hepatitis B core antigen (anti-HBc) alone was present in 13 (11%). The relatives with the highest frequency of HBsAg positivity were the offspring of the propositus, followed by the nieces and nephews and the grandchildren. Anti-HBs and anti-HBc were detected most often in the spouses and non-blood relatives. Evidence for past and present hepatitis B virus (HBV) infection was more frequently found in the Asian family members when compared to the non-Asians. The e antigen (HBeAg) was present in 38% of the HBsAg positive individuals, including four with PHC; antibody to HBcAg (anti-HBe) was rarely detected. These results indicate that clustering of HBV infection was commonly present in family members of patients with PHC. The HBsAg positive individuals may be major contributors to the endemic pool of the virus, and may themselves be potential cases of chronic active type B hepatitis, cirrhosis, and PHC.

A retrospective study has been performed in 149 subjects with present or past HBs antigenemia. The group consisted of 8 asymptomatic carriers, 90 with acute hepatitis, 7 with fulminating hepatitis, 27 with chronic hepatitis, 16 with cirrhosis and 1 with hepatoma. The changes from one clinical condition to another, the sources of infection, the percentage of acute hepatitis in the history of chronic hepatitis cases and the working capacity an average of two years after the infection were studied. HBe antigen and the corresponding antibody were detected by immunodiffusion and the results compared with the clinical course.

The plasma lecithin: cholesterol acyltransferase was determined in patients with various liver diseases and the relationship between this enzyme activity and the other liver function tests were studied including long term observations. Lecithin: cholesterol acyltransferase activity in fulminant hepatitis and liver cirrhosis showed a significant decrease in comparison with normal volunteers. Although the enzyme activity of hepatoma showed significant decrease, they were ascribed to the influence of concomitant liver cirrhosis. The enzyme activity showed insignificant changes in the acute and chronic hepatitis and alcoholic liver disease. Lecithin: cholesterol acyltransferase activity was correlated with the concentration of cholesterolester rather than with the ratio of esters to cholesterol. In addition, it was well correlated with pseudocholine esterase and serum albumin. The lecithin: cholesterol acyltransferase activity in the cases during follow-up period varied in good parallel with cholesterol-esters concentration and pseudocholine esterase in the cases with acute hepatitis; with serum albumin in the cases with liver cirrhosis. Furthermore, it varied inversely with SGPT in the cases with acute hepatitis. In a case with hepatoma, lecithin: cholesterol acyltransferase activity decreased more sharply than the cholesterolesters concentration and serum albumin immediately before death.

The HBeAg was detected in 5 of 24 patients with acute type B hepatitis (20.8%), 33 of 95 with chronic hepatitis (34.7%), 6 of 33 with liver cirrhosis (18.2%), and 3 of 39 with hepatocellular carcinoma (7.7%). On the other hand, anti-HBe was found in 4.2% of acute hepatitis, 18.9% of chronic hepatitis, 9.1% of liver cirrhosis, and 12.8% of hepatocellular carcinoma. We found that an early detection of HBeAg in patients with acute hepatitis is of no prognostic value, but its persistence may provide the earliest evidence of potential chronicity. In chronic liver diseases, HBeAg-positive cases showed remarkable fluctuations of serum transaminase levels, severe histological changes and poor responses to treatment. Many of the HBeAg-positive patients lost their initial positivity of HBeAg within six months or one year and in some cases serocoverted to anti-HBe after acute exacerbation. Follow-up study more than several years revealed that the presence of anti-HBe reflect an inactive stage and a more favorable outcome, whereas persistence of HBeAg may provide an active and continuing hepatocellular damage. From these results, we believed that serial measurements of HBeAg/anti-HBe system are useful prognostic marker in patients with HBsAg-positive liver disease.

Aleutian disease is a chronic persistent viral infection of mink characterized by hypergammaglobulinema, generalized plasmacytosis, sclerosing glomerulonephritis, polyarteritis, and plasma cell hepatitis with bile duct proliferation. The development of hepatic lesions was studied both light- and electron-microscopically in mink experimentally infected with Aleutian disease virus. Fifteen normal and 99 mink experimentally infected with Aleutian disease virus were used. Experimental mink were killed in intervals from 3 weeks to 23 months after infection, and liver sections were processed for both light- and electron-microscopic studies. Experimentally infected mink developed portal and intralobular lymphocytic and plasmacytic infiltrates in the liver 3 weeks after infection. Four to five weeks after infection there was evidence of early bile duct proliferation that began as an outgrowth of the portal bile ducts. Three to five months after infection a marked bile duct proliferation was present in some of the portal triads and adjacent liver lobules; but there was no tendency of these lesions to progress into biliary cirrhosis. Ultrastructural characteristics of proliferating bile duct cells were marked deformation, formation of multiple cell layers, reduction in the number of microvilli and desmosomes, and infiltration of the epithelial cells by lymphoid cells and plasmacytes. The hepatic lesions either develop by direct virus stimulation or by the deposition of virus-antibody complexes.

Lipoprotein-X (LP-X) in the serum of infants with persistent jaundice is indicative of cholestasis. In early infancy biliary atresia and biliary agenesis are the most common cause of cholestasis, whereas neonatal hepatitis is a less frequent cause of cholestasis. The authors introduced and described the qualitative and quantitative methods of LP-X determination for diagnostic purposes. LP-X estimations were carried out in 9 children with persistent jaundice. LP-X was found to be present in 4 infants-in 2 with complete absence of extrahepatic biliary tracts, in 1 with extrahepatic biliary atresia and in 1 with hypoplastic extrahepatic biliary tract. LP-X was also found in a 5 year old boy with mechanical occlusion of bile ducts caused by a malignant tumor ( rhabdomyoblastoma ), and in 3 year old girl with inborn enzymatic liver dysfunction. In this case LP-X concentration was estimated before and after 3 week course of cholestyramine, after which there was a 35% decrease in the LP-X concentration. In a 4 month old child LP-X was not found in spite of the absence of extra and intrahepatic biliary tracts. This finding may be explained by the far advanced hepatic cirrhosis. The authors stress the importance of introducing of LP-X estimation in the differential diagnosis of jaundice in early infancy.

Increased incidence of renal insufficiency is observed in severe damage of liver parenchyma such as fulminant hepatitis, decompensated cirrhosis of the liver, septic cholangitis and the different forms of obstructive jaundice. Functional circulatory disturbances of the kidney, especially of the renal cortex, are of importance in the aetiology of this condition. Dopamine, at a dosage as low as 3 gamma/kg/min leads to an improvement in renal blood flow and also to an increase in hepatic blood flow. These observations are of therapeutic importance. Some important circulatory and functional parameters of both these organs, which influence each other under normal and pathological conditions, were studied in the presence of dopamine and the following results were obtained: 1. An investigation of the intrarenal haemodynamics with 133 Xenon in patients with severe cirrhosis of the liver and in patients with obstructive jaundice resulted in an increase of 91% in the mean renal blood flow. The blood flow in the renal cortex increased by 36.2% and in the renal medulla 18.5%, whereas the renal fat tissue showed no change. Compartment I, which was diminished as compared with the control value, also increased. The percentage contribution of the mean renal blood flow and the blood flow of the renal cortex towards the cardiac output was greater under the influence of dopamine; hence a greater part of the cardiac output flows into the kidney under dopamine. 2. The glomerular filtrate and the renal plasma flow increased under dopamine (13.5% and 43.1%, respectively). The increase was greater in compensated than in decompensated cirrhosis. In patients with obstructive jaundice there was a smaller increase in both these parameters than in patients with cirrhosis in the presence of dopamine. No connection was found between the increase in renal plasma flow with dopamine and the blood levels of bilirubin, cholinesterase, GOT and the Normotest. 3. The urinary output of sodium increased by 191.4% with dopamine. Patients with an initial renal plasma flow value of over 300 ml/min had a higher sodium output. These patients also eliminated more sodium under the influence of dopamine than those with an initial renal plasma flow value of under 300 ml/min. 4. Blood flow determinations in the portal vein and the hepatic artery in man, obtained during operation, showed an increase in portal flow of 28.5% and hepatic artery flow of 6.3% in response to dopamine. The percentage contribution of portal blood flow towards the cardiac output increase on dopamine administration. The functional hepatic blood flow, analyzed with 131-J-BSP, did not change. The wedged hepatic vein pressure, which is a good measure of portal pressure, increased on average by only 7% with dopamine at a dosage of 3 gamma/kg/min, but by 20.3% with twice the dosage. Dopamine did not cause a change in hepatic blood volume; hence, blood sequestration in the liver can be excluded in response to the dopamine-evoked increase in portal blood flow. 5...

Liver enzymes were followed in 99 patients treated with D-penicillamine for rheumatoid arthritis. In six abnormalities were found which consisted of elevated levels of lactic dehydrogenase. ALAT/ASAT, alkaline phosphatases or combinations of these. The changes were reversible on stopping the drug with one possible exception. No evidence of biliary cirrhosis, chronic active hepatitis or HBag-associated hepatitis was found. Liver biopsy was performed in 4 cases--one was taken 2 months after the treatment was discontinued, and was normal. One biopsy showed mild inflammatory changes, whereas in two histologic evidence of toxic liver necrosis was present. Liver damage should be included among possible complications of D-PA treatment.

Five patients with alpha-1-antitrypsin deficiency (PiZ) are reported. All these patients presented with the neonatal hepatitis syndrome and two fo them had developed cirrhosis at ages 5 and 8 years, respectively. Three patients, ages 1, 9 and 21 years, are asymptomatic. The oldest patient, 21 years of age, has only mild histologic changes in the liver. The prognosis for patients with alpha-1 antitrypsin deficiency (PiZ) presenting with neonatal hepatitis is not necessarily grave, a finding that differs from previous observations.
