Investigation of humoral immunity against hepatocellular membrane antigens in patients with chronic active hepatitis and other liver diseases showed two different immunofluorescence patterns of IgG on hepatocyte membranes. A linear pattern was seen in HBsAg-negative hepatitis, but HBsAg-positive cases and some of protracted, acute hepatitis B had a granular pattern. In patients with IgG bound to hepatocytes, continuing necrosis of parenchymal liver cells was seen. Conversely, hepatocytes without bound IgG were found in cases of chronic active hepatitis in remission, acute viral hepatitis without HBsAg and chronic persistent hepatitis, in "healthy" HBsAg-carriers and in patients with fatty liver or alcoholic cirrhosis. A liver-membrane autoantibody in serum, proved by fixation on membranes of isolated rabbit hepatocytes, could be demonstrated only in HBsAg-negative chronic active hepatitis with elevated IgG-concentrations. The results support the existence of different pathogenetic types of chronic active hepatitis, a so-called autoimmune type and a hepatitis virus-B-induced type.

On routine hospital admission, 23,714 patients received a 28-test serum metabolic profile. The 33 most common diseases (4,132 patients) of liver, pancreas, and gallbladder (LPG) had unique chemical templates averaging 15 significant serum deviations. Each LPG disease differed from all others by elevations of both leucine-aminopeptidase (LAP) and alkaline phosphatase (AP) levels. LAP level was low or normal and serum glutamic oxaloacetic transaminase (SGOT) and AP levels were elevated in 43 non-LPG diseases. Patients with acute and chronic pancreatitis had elevated amylase levels. The four nonmalignant diseases of the gallbladder were associated with normal levels of amylase and lactic dehydrogenase (LDH); except for silent cholelithiasis, each showed elevated total bilirubin (BIL) levels. Patients with solitary or scattered lesions of the liver had normal bilirubin levels (2,115 patients), and those with diffuse interstitial or parencymal disease had elevated BIL levels. Cancer patients had elevated LDH and alpha1 globulin (A1G) levels, but low albumin levels. The importance of comprehensive liver profiles in the treatment of psychoses is emphasized by significant liver damage in a number of these patients. A1G was normal and LDH was elevated in patients having mononucleosis, hepatitis, lupus erythematosus, alcoholism, and alcoholic cirrhosis.

The occurrence of hematologic changes has been studied in 256 patients with various liver diseases. Macrocytosis on smears and by MCV was found in 50% of acute and in over 70% of chronic liver diseases. MCV increased from 98 +/- 8 mu3 (acute hepatitis) up to 108 +/- 12 mu3 in alcoholic cirrhosis. Anemia, which occurred rarely in hepatitis but in 67% of cirrhosis, was always macrocytic, not correlating with reticulocyte counts. Target cells were found in 20% of acute hepatitis and 41% of cirrhosis. In patients with chronic liver disease target cells were associated with macrocytosis and increased bilirubin. Thrombocytopenia was found in 11% of acute, in 53% of chronic inflammatory and in over 60% of cirrhotic liver disease.

Electron microscope studies of liver biopsies in 32 cases of hepatitis with Australia antigen (aggressive chronic hepatitis, polyarteritis, hepatitis on alcoholic cirrhosis and in kidney transplants) showed original intranuclear formations. They are different from the usual viral type particles connected with Australia antigen and appear to be formed of dense, granulofilamentous accumulations, scattered at random in the nucleus, sometimes in close proximity of nucleoles and nuclear bodies. Within these accumulations outlines of complete or partial rounded particles have been observed the morphology of which resembled that of the usual intranuclear particles. Comparison with former descriptions of the chronological aspects of viral replication allowed the author to refer to these formations by the term of "viroplasms". Thus, they are considered representative of an intermediate stage in the formation of the nuclear particles. This interpretation would add an argument to the notion of nuclear replication of the particles related to Australia antigen.

Among the several methods employed for the detection of hepatitis B antigen (HBAg) and hepatitis B antibody (HBAb), radioimmunoassay is considered to be the most sensitive and specific. This paper describes a radioimmunoprecipitation test (RIP) for HBAg and HBAb standardized in our laboratory; it consists of a double-antibody precipitation test in a micro-titer system employing 125I-labeled HBAg. The test is compared with double immunodiffusion (ID) and with counterimmunoelectrophoresis (CEP) in the detection of HBAg and HBAb in healthy persons and in patients with acute and chronic liver disease. RIP is 20,000 times more sensitive than ID and 2,500 times than CEP when HBAg is tested, and 40,000 times more sensitive than ID and 10,000 times than CEP for the antibody detection. Moreover the method is reproducible and specific for HBAg and HBAb. With this test the frequency of HBAg in healthy persons was 0% in subjects without any known contact with antigenic material, 0.80% in hospital personnel and 1.17% in high risk personnel (laboratory technicians, blood products workers, ecc.). In acute viral hepatitis the frequency of HBAg was 90% at the admittance to the hospital and 70% at the dimission, while CEP detected a frequency of 85% and 20% respectively. In chronic liver disease the frequency of HBAg with the RIP method was 83.3% in chronic persistent hepatitis, 42.8% in chronic aggressive hepatitis, 23% in cryptogenic cirrhosis and 16.6% in alcoholic cirrhosis. The frequency of HBAb detected with RIP was 4.50% in subjects without any known contact with antigenic material, 6.45% in hospital personnel, 0.41% in high risk personnel, 20% in acute viral hepatitis at the admittance to the hospital and 50% at the discharge, 25% in chronic persistent hepatitis, 14.2% in chronic aggressive hepatitis, 15.3% in cryptogenic cirrhosis and 50% in alcoholic cirrhosis. The high frequency of antibody in healthy persons with no history of hepatitis or parenteral exposure to blood transfusion suggests a widespread diffusion of hepatitis B infection and the possibility of a nonparenteral route transmission. The frequency of HBAg and HBAb in chronic liver disease as detected by a very sensitive method rises the question of a possible role of hepatitis B virus in the pathogenesis of the disease.

In the last four years, 551 liver transplantations have been performed at the Paul Brousse center, for a total of 840 liver transplantations performed from 1984 to 1992. Several changes have been observed in the field of liver transplantation in the past years. The field of immunosuppression was marked mainly by the advent of FK506 as a preventive treatment of rejection and as a treatment of cortico-resistant rejection. Results are still under analysis. From the surgical viewpoint, the main modification was the advent of UW solution, which extends cold ischemic time. However, our policy was to maintain the cold ischemic time at less than 12 hours. Primary indications for liver transplantations have changed with an increase in the rate of patients transplanted for cirrhosis related to hepatitis virus infection: from 24% in the period 1984-1988 to 42% in the period 1989-1992. The difference was due mainly to HCV-related cirrhosis, which increased from 8% to 20%. Alcoholic cirrhosis was a rare indication in the period 1989-1992 (3.4%); however, it was an increasing indication in the last 2 years. In order to improve the long-term results, major attention was given to the recurrence of initial liver disease. In patients transplanted for HBsAg-positive liver disease, long-term passive anti-HBs immunoprophylaxis was administered, which reduced the rate of HBV recurrence in patients without HBV replication before transplantation.(ABSTRACT TRUNCATED AT 250 WORDS)

To assess the role of the hepatitis C virus in patients with unexplained chronic liver disease, we tested for the presence of anti-hepatitis C antibody (anti-HCV) in the stored serum of patients with cryptogenic cirrhosis and a variety of other chronic liver diseases. The anti-HCV assay was performed by both the enzyme-linked and recombinant immunoblot methods in 16 patients with cryptogenic cirrhosis. Eight of these 16 patients (50%) were seropositive. Six of these eight patients were born outside of the United States, compared with only one of eight seronegative patients (p = 0.021). Of the anti-HCV-positive cryptogenic cirrhotic patients, 50% also had markers of previous hepatitis B infection, compared with only 12.5% of seronegative patients. Evidence of anti-HCV positivity was found in 10%, 19%, 0%, and 0% in patients with alcoholic cirrhosis, autoimmune hepatitis, primary biliary cirrhosis, and primary sclerosing cholangitis, respectively. We conclude that in a suburban American population, hepatitis C accounts for a significant percentage of patients with presumed cryptogenic cirrhosis. Unrecognized risk factors may account for a higher prevalence of HCV in foreign-born patients with cryptogenic cirrhosis. A low prevalence of anti-HCV positivity is found in other forms of chronic liver disease.

There have been many reports on renal lesions of alcoholic cirrhosis, but not on those of post-hepatitis cirrhosis (PHC) up to present. A clinical and pathological observation on PHC was carried out prospectively in 18 and retrospectively in 34 cases. Renal specimens were examined with light and electron microscopy and immunopathological methods (immunofluorescence and peroxidase anti-peroxidase). Clinically, recurrent gross hematuria was observed in 2 and wild urinary abnormality in 17 cases. One case developed renal failure and the remaining 32 cases had no clinical evidence of renal involvement. Light microscopy showed wild mesangial lesions in 44 cases and glomerular basement membrane (GBM) thickening with segmental splitting in 29 and diffuse splitting in 2 cases. Massive protein deposition was found in the GBM, mesangium (Ms) and tubular basement membrane as well as the epithelium and endothelium. Immunopathological examination showed massive deposition of various immunoglobulins and complements in GBM and Ms, with IgG dominant in 8, IgM dominant in 7, IgA dominant in 6 and "full house" in 11 cases. HBsAg was detectable in GBM and Ms in 5 cases (9.6%) and HBcAg in one. Focal interstitial fibrosis and lymphocytic infiltration were found in 15 (28.3%). Our data revealed that renal lesions of post-hepatitis cirrhosis are different from those of the so-called "cirrhotic glomerulonephritis" in certain aspects. They are characterized by definite GBM involvement and massive deposition of immunoglobulins and complements. Its pathogenesis may be more complicated than that of other types of liver cirrhosis.

The pathogenesis of alcoholic liver disease is unclear. The recent literature on pathogenic factors, including direct effects of ethanol and its proximate metabolite acetaldehyde, associated nutritional factors, the formation of acetaldehyde-protein adducts, associated immune alterations, and the potential for liver injury due to coexisting hepatitis virus infection, is highlighted. The therapy of patients with advanced alcoholic liver injury, especially alcoholic hepatitis, is also controversial. It seems reasonable that all patients should receive adequate nutrition even if parenteral or enteral supplementation is required. Corticosteroid administration may benefit those patients with alcoholic hepatitis who have coexisting spontaneous hepatic encephalopathy and no gastrointestinal bleeding. For patients with complications from end-stage alcoholic cirrhosis, liver transplantation should be considered, as the patient with alcoholic cirrhosis does as well after liver transplantation as those patients with other forms of end-stage liver disease.

The purpose of the study was evaluation of the usefulness of selected indices of humoral immune responsiveness in the differential diagnosis of post-alcoholic hepatocellular damage. The study was carried out in 105 patients: 10 patients with a history of alcohol abuse without clinical and biochemical evidence of hepatocellular damage, 2) patients with alcoholic cirrhosis, 3) patients with post-inflammatory cirrhosis. The prognostic usefulness of the determinations of serum IgM, C3 and C4 complement components and circulating immune complexes in early diagnostic of alcoholic liver disease was demonstrated. It was noted also that increased serum IgA level may be a useful index differentiating of cirrhosis after hepatitis from alcoholic cirrhosis.
