We have studied the cytotoxicity against rabbit liver cells of lymphocytes from the peripheral blood of 71 patients with various liver diseases. The group with chronic active hepatitis and three patients with acute alcoholic hepatitis showed significantly higher mean values of lymphocytotoxicity (P less than 0.001) compared with the other patients with chronic persistent hepatitis, post-necrotic fibrosis and cirrhosis. Wilson's disease, and prolonged viral hepatitis. The mean cytotoxicity of these last groups did not differ significantly from controls. In four out of six patients with chronic active hepatitis a significant decrease of lymphocytotoxicity was found after immunosuppressive therapy with oral prednisolone. A good correlation between the lymphocytotoxicity test and histological signs of activity suggests that a cell-mediated immune aggression is present in this disease.

Immunohistochemical evaluation of Cu, Zn- and Mn-superoxide dismutase (SOD) activity in various viral liver diseases was performed by the peroxidase-conjugated antibody indirect method. Anti-human Cu, Zn-SOD (rabbit) and anti-human Mn-SOD (guinea-pig) derived and purified from SOD of human erythrocytes and placentas were used to determine SOD distribution in liver tissues. SOD in the liver tissues was detected in 68 inpatients of our unit. They consisted of 23 cases with chronic hepatitis caused by hepatitis B virus (13) and hepatitis C virus (10), 24 with liver cirrhosis caused by hepatitis B virus (5) and hepatitis C virus (19) (15: compensatory, 9: decompensatory) and 21 with hepatocellular carcinoma caused by hepatitis B virus (2) and hepatitis C virus (18) complicated of liver cirrhosis. In viral liver diseases, SODs in the liver tissues were distributed to hepatocytes mainly in the pattern of cytoplasmic diffusion. The incidence of immunohistochemical Cu, Zn-SOD and Mn-SOD were 47.8% and 56.5% in chronic hepatitis, 93.3% and 86.7% in compensated liver cirrhosis, 11.1% and 22.2% in decompensated liver cirrhosis, respectively. The aggression of viral liver disease was accompanied with the decrease of SOD concentration in the liver tissues. Hepatocellular carcinoma cells were negative for Mn-SOD in all cases, and weakly positive for Cu, Zn-SOD in 2 out of 21 cases. Comparatively strongly positive SOD findings were obtained from normal regions neighboring carcinomas. A close relationship between the depletion of SOD in liver tissues and carcinogenesis in viral liver diseases was observed.

From a series of 100 patients hospitalized for chronic hepatitis B infections (HBV), 51 chronic carriers of the HBs antigen without elevated aminotransferases or circulating HBV DNA were studied retrospectively. They had no unusual epidemiological or clinical features compared to the other patients, but were distinguished by their normal liver function tests, except for 5 cases of isolated hypergammaglobulinemia. Hepatic biopsies performed on 28 patients showed minor lesions or normal tissue in 61% of the cases and persistent chronic hepatitis (PCH) in 39% of them. No clinical or biological abnormality was significantly associated with PCH, which was attributed to a delta hepatitis (HDV) superinfection in only one case. There were no cases of active chronic hepatitis or cirrhosis. The significance of the histological lesions in the absence of HBV replication or other symptoms of hepatocyte aggression was not elucidated; their longterm prognosis is not known even if no other difference, identifiable by usual methods, seems to exist between these "pseudo-healthy" carriers and real healthy carriers of HBV.

Primary biliary cirrhosis (PBC) of the liver is considered to be an autoimmune liver disease in which an immune aggression is directed against small biliary ducts--mitochondrial antigens of a biliary epithelium. The targets of an immune aggression in PBC may also be the histocompatibility antigens of the biliary ducts epithelium. This makes PBC resembling so-called disease "graft against host". The destruction of bile ducts in PBC is brought about through the mechanisms of an immune cytolysis and is manifested morphologically by the symptoms of the delayed hypersensitivity response. Cholangiole proliferation develops along the ductal destruction, sclerotic changes and cholestasis increase in their intensity. Small-nodular cirrhosis develops at the final stage of disease. Systemic manifestations of PBC are associated with a circulation of immune complexes containing hepatobiliary antigens. Cross-immune reactions are also of importance in the mechanisms of extrahepatic lesions.

A 54-year-old woman with obesity, type II diabetes mellitus, hyperlipidemia, and massive hepatomegaly was found to have severe steatosis and cirrhosis on liver biopsy. Complete evaluation led to the diagnosis of fatty cirrhosis associated with obesity and diabetic mellitus. She underwent four months of fasting with a protein-carbohydrate and vitamin-mineral liquid supplement to control her weight and metabolic abnormalities and to evaluate the effect of this diet on her liver disease. She lost 40 pounds to ideal body weight, normalized her serum glucose and lipids, and decreased total liver height by one third. Liver biopsy at the completion of her diet showed inactive cirrhosis and complete resolution of steatosis. Supplemented fasting with only modest weight loss can safely resolve fatty liver in obese diabetics with nonalcoholic steatosis and cirrhosis. Aggressive dietary approaches to achieve long-term weight loss deserve study in this subgroup of diabetics with unexplained chronic liver disease.

To establish the impact of transplantation on the course of chronic hepatitis B liver disease we performed a prospective study of the clinical and pathological sequelae of hepatitis B disease in all 22 patients who had renal allografts that functioned for more than 1 year and who were hepatitis B surface antigen (HBsAg)-positive following transplantation. No patient converted to HBsAg-negative. During a mean follow-up of 83 months serial liver biopsies were performed in 20 patients and 1 liver biopsy was available in the remaining 2 patients. Eleven patients died of liver disease, 5 of whom died of hepatic failure, 3 with hepatoma, 2 of gastrointestinal hemorrhage, and 1 of ascites with pleuroperitoneal fistula. Aggressive liver disease was observed in the vast majority of patients: 12 ultimately developed cirrhosis, (mean follow-up 81 months), 6 chronic active hepatitis (mean follow-up 93 months), 3 chronic persistent hepatitis (mean follow-up 89 months), and in 1 patient the presence of HB virus in hepatocytes was the sole morphologic alteration (follow-up 42 months). There was a marked tendency to progression in that 82% of patients with virus only, reactive hepatitis, or chronic persistent hepatitis on initial biopsy subsequently developed chronic active hepatitis or cirrhosis. For comparison, 10 HBsAg-positive patients whose renal failure had been treated by hemodialysis were also studied over a comparable period. Four patients converted to the negative state. Biochemical evidence of persistent liver dysfunction occurred in only 1 patient and no patient has died from complications of liver disease. We conclude that in the immunosuppressed renal transplant patient HB infection often results in the development of cirrhosis, leading to death from hepatoma and hepatic failure. This course is worse than that in dialysis patients. Renal transplantation of HBsAg-positive patients with end-stage renal failure may be inadvisable.

The aim of this study was to test the effect of cholestyramine on the hepatotoxic reactions due to paracetamol overdose. Wistar rats receiving a 5% aqueous solution of paracetamol at a dose of 750 mg/kg intraperitoneally showed a extensive necrosis within 24 hrs, whereas the addition of 4% cholestyramine to the diet inhibited the hepatic aggression. The protective mechanisms of cholestyramine against paracetamol overdose were admitted to be identical to those observed in the inhibition of liver cirrhosis induced by CCl4. The authors' hypothesis is that the paracetamol aggression and cholestyramine protection are both bile salts related.

Histological features of chronic active and chronic persistent hepatitis were observed in mice, rabbits and non-human primates infected with either Schistosoma mansoni and Schistosoma japonicum. In early infection hepatitis appeared as a reactive change due to liver damage caused by the deposition of schistosome eggs, but portal and septal cellular infiltrations tended to remain long after parasite aggression had diminished or disappeared, either spontaneously with time or after chemotherapy. In rabbits, and to a lesser degree in monkeys, a picture of chronic active hepatitis was present, with evolution to cirrhosis in the former. The experimental findings indicate that schistosomiasis has the potential to induce chronic hepatitis and suggest that the current assumption that chronic hepatitis seen in humans with schistosomiasis is always due to concomitant viral infection should be reviewed.

A 53-year-old man with alpha-1-antitrypsin deficiency had an 8-year history of progressive dyspnoea and two episodes of bleeding oesophageal varices with liver decompensation. After the diagnosis of terminal pulmonary emphysema (Fig. 1) and liver cirrhosis with progressive liver failure was made, he was accepted for combined lung and liver transplantation. METHODS. Anaesthesia was induced with thiopentone and fentanyl and maintained with fentanyl, midazolam, and isoflurane. After relaxation with succinylcholine, the patient's trachea was intubated with a left endobronchial double-lumen tube. Haemodynamic monitoring included arterial, central-venous, pulmonary-artery, and capillary-wedge pressures and cardiac output measurement. Ventilatory monitoring consisted of pulse oximetry, side-stream spirometry, and continuous measurement of arterial and mixed-venous blood oxygen saturation with fibreoptic catheters. A left single-lung transplantation was performed under one-lung ventilation without cardiopulmonary bypass. Prostacyclin was infused to reduce pulmonary vascular resistance. The transplant was ventilated separately with 50% oxygen and positive end-expiratory pressure of 8-10 cm H2O, and then liver transplantation was carried out. The institution of veno-venous bypass during the anhepatic phase failed because of portal-vein and axillary-vein thrombi. RESULTS. Total operation time was 6 h 30 min. Clamping of the left pulmonary artery lasted 45 min and the duration of the anhepatic phase was 92 min. Ventilation and oxygenation during lung transplantation caused no problems (Table 1). Clamping of the left pulmonary artery caused a slight increase in pulmonary vascular resistance (104 to 124 dyn.s.cm-5) and mean pulmonary artery pressure (25 to 27 mm Hg) without a decrease in cardiac index (Table 2). During the anhepatic phase with exclusion of the portal vein and inferior vena cava, a marked decrease in cardiac index (-27.2%) was seen (Table 4). The operation required substitution with 10 units packed red blood cells, 12 units fresh frozen plasma, and 5 platelet concentrates. The post-operative course showed normal liver graft function (Table 5). Acute pulmonary rejection on the 7th day was treated successfully with methylprednisolone. The patient's trachea has extubated 10 days after transplantation and he was discharged from the intensive care unit 2 weeks later. CONCLUSION. The management of this combined lung and liver transplantation was performed according to the experience with isolated lung and liver transplants in our hospital. Aggressive haemodynamic and ventilatory monitoring, including systemic and pulmonary arterial fibreoptic catheters, seems of particular importance in such high-risk procedures.
