In eight patients with clinical sure Vogt-Koyanagi Harada-syndrome (VKHS) immunological examinations were performed. We tested whether there were signs of former or present infections (measles HHT and complement fixation test (C.F.T.), rubella HHT, hepatitis HBs-antigen, adenovirus AG, varicella-zoster C.F.T., herpes simplex C.F.T., cytomegaly IgM and IgG, toxoplasmosis immunofluorescence, tuberculosis Middlebr. Dubois). In none of all cases we could find HLA B12. The rheumatic tests, LDH, albumin an electrophoresis, coeruloplasmin and haptoglobin were negative. The uveal pigment failed to stimulate the leucocyte cultures from VKHS-patients in leucocyte-migration-inhibition-test and in leucocyte-adherence-inhibition-test.

The glycoproteins (GP) of 329 patients with liver diseases and 60 clinically healthy subjects were complexly studied: sialic acid, orozomucoid, haptoglobin, ceruloplasmin, cholinesterase, hexosamine and fucose. Modern laparoscopic, bioscopic, histochemical and histomorphological methods were used in making the diagnosis and determination of the disease phase; The liver diseases are characterized by quantitative and qualitative differences in the character of the GP changes in serum. GP are mostly changed in acute viral hepatitis, cirrhosis, extrahepatic cholestasis and liver tumours, less in chronic aggressive hepatitis and no change in chronic persistent hepatitis and steatosis. The complex GP study is of significance in the characteristic of the activity of the pathological process, in the specification of the liver function as well as for the prognosis of a certain disease.

Acetaldehyde in non-toxic doses (15.6 micrograms per start) causes in the inhibition test of the migration of leucocytes an inhibition of the migration in 6/13 of the patients with alcoholic hepatitis, a stimulation of the migration in 6/11 of alcohol cirrhoses. Healthy (n = 16) persons, patients with alcoholic fatty degeneration of the liver (n = 3) as well as non-alcoholic liver diseases (chronic persisting hepatitis, n = 11; chronic active hepatitis, n = 8, cirrhosis, n = 7) did not show this cellular immune reagibility. The inhibition of the migration and the stimulation of the migration, respectively, might develop by hapten autoantigen complexes (altered cytoskeleton?) with release of the factors of inhibition of migration and stimulation of migration, in which case the role of a hapten belongs to acetaldehyde. The results of the tests did not correlate with functional and histological findings of the liver, with the actual consumption of alcohol and also not with haptoglobin phaenotypes. When it is postulated that by acetaldehyde also the release of further lymphokines is mediated, origin and progression of alcoholic hepatitis and alcoholic cirrhosis might be explained immunopathogenetically.

Forty-three women who had viral hepatitis one or more years ago and 35 healthy women who were age and parity matched were given an oral contraceptive containing 0.05mg ethinyl estradiol and 0.5mg levonorgestrel for six consecutive months. Liver function tests (serum bilirubin, SGOT, SGPT and serum alkaline phosphatase) and serum proteins (total, albumin, globulins, ceruloplasmin, haptoglobin and alpha-1 antitrypsin) were measured before beginning treatment and after three and six months of use. Past hepatitis women experienced increased unconjugated bilirubin, SGOT, SGPT and alkaline phosphatase levels throughout the six months while the control women showed less pronounced changes during the first three months with tendency to reversion to normal during the subsequent three months; the group X time of test interactions were significantly different between the two groups. Serum haptoglobin decreased significantly in both groups but the past-hepatitis group showed a more persistent change with time. Changes also occurred in serum albumin, alpha-1 and beta globulins, ceruloplasmin but without group effect or group X time interactions.

The study was aimed at the assessment of the immune system function of a large group of patients with early phase of acute viral type B hepatitis, who were subsequently follow-up in order to select those developing chronic forms of the infection. It was assumed that re-assessment of their initial immunological status with regard to further evolution of the infection would show some factors predictive of chronic active hepatitis development. Chosen immunological parameters: circulating blood lymphocyte sets and subsets, immunoglobulin concentrations, presence of non-specific immune complexes and concentrations of randomly chosen acute phase proteins (ceruloplasmin, transferrin, haptoglobin, alpha-acid glycoprotein, C3 and C4 complement components) were evaluated in 104 acute viral type B hepatitis patients, aged 18-50, on the days 8, 10, 15, 30, 40, 60, 80 and 130 of the illness. After mean of 744 days, 56 patients reported to final follow-up examination, 15 of whom presented with symptoms of chronic sequelae of acute HBV infection (elimination phase of chronic aggressive hepatitis, chronic persistent hepatitis, or integration phase of HBV infection). Behaviour of cellular immunity parameters, immunoglobulin concentrations, presence of immune complexes or non-specific antibodies, however varied in individual patients, showed no correlation predictive of chronic sequelae of the infection. Significant differences between patients who subsequently developed chronic active or chronic persistent hepatitis were found, however, with regard to all the acute phase proteins tested, most prominent in case of C3 and C4 complement components, haptoglobin, transferrin and ceruloplasmin.(ABSTRACT TRUNCATED AT 250 WORDS)

A panel of four novel human hepatoma cell lines was isolated from a single tumor from a male individual. BC1, B16 and B16A2 lines were well differentiated, while cells of the B9 line were only poorly differentiated, being essentially negative for the functions analyzed. These cell lines have been surveyed for expression of a large set of plasma proteins, accumulation of liver-specific mRNAs and DNA-binding activity of ubiquitous and liver-enriched transcription factors. BC1 cells expressed the highest levels of albumin mRNA, whereas B16 and B16A2 cells accumulated the largest amounts of haptoglobin mRNA. In addition, B16 and B16A2 cells were unique in that they expressed CYP2E1 mRNA, a species absent from the available human liver cells, including HepG2 hepatoma cells, and 3-methylcholanthrene-inducible CYP1A2 mRNA. The activities of genes encoding transcription factors were evidenced in all four cell lines which expressed mRNAs for nuclear factor interleukin 6 and hepatocyte nuclear factor 1 (HNF) together with the DNA-binding activity of NFY and AP1 nuclear proteins. Strikingly, HNF-1 and HNF-4-like DNA-binding activities were restricted to BC1, B16 and B16A2 cells, supporting the idea of the potential role of these (or closely related) factors in the maintenance and/or in the establishment of the differentiated phenotype. B9 cells contained variant HNF1-like DNA-binding activity, similar to dedifferentiated rat hepatoma cells of the H5 line. CCAAT/enhancer-binding protein and HNF-3-like activities were found in all cell lines, although at a lower level and/or activity in B9 cells. Finally, transfection experiments of plasmids containing the whole hepatitis-B virus genome demonstrated that B16 cells, but not B9 cells, were able to support hepatitis-B virus replication and virion production, in agreement with the notion that HNF-1 activity is necessary for viral replication. We believe that the specific complement of transcription factors expressed in the differentiated BC1, B16 and B16A2 cells, and in the poorly differentiated B9 cells, will allow studies on the regulation of hepatic gene expression in these human lines, and will also aid the analysis of xenobiotic metabolism and the biology of hepatitis-B virus replication.

Haptoglobin phenotypes have been shown in human medicine to be related to the prevalence of various diseases. Furthermore, abnormal glycosylation of haptoglobin has been reported as a consequence of liver disease, cancer and immunological disorders in man. To our knowledge, similar findings have not, so far, been reported in canine disease. The present paper describes a method for investigation of canine haptoglobin phenotypes and of microheterogeneity caused by altered glycosylation. The method consisted of isoelectric focusing (IEF) of dog serum, followed by immunoblotting. The results indicated the existence of only one canine haptoglobin phenotype with a characteristic microheterogeneity pattern in healthy dogs. Changes in this pattern were found in serum from dogs with liver disease, predominantly chronic progressive hepatitis, and with different kinds of anaemia. Pretreatment of serum with neuraminidase or glycopeptidase F (PNGase F) resulted in identical IEF patterns of haptoglobin from healthy and diseased dogs. Moreover, a fucose-specific lectin was capable of binding to some of the abnormal haptoglobin fractions, mainly those found in association with anaemia. The changes described were interpreted as alterations of the carbohydrate content, with or without fucosylation, of some haptoglobin fractions.

Serum haptoglobin levels have been measured in 115 cases of widely differing liver disease. Although low levels were found in some cases of cirrhosis and a number of patients with obstructive jaundice had increased levels, 70% of the values fell within the normal range. The estimation was of no help in distinguishing between intra- and extrahepatic obstructive jaundice. A characteristic pattern was observed in infective hepatitis, and a falling serum haptoglobin in the presence of increasing jaundice is diagnostic of the latter condition. The cause of these changes is uncertain. Low levels could not be accounted for by increased red cell breakdown and there was no correlation with the serum albumin level. Prednisolone therapy produced a rise in serum haptoglobin level in cirrhosis, which was accompanied by an improvement in liver function. Temporary rises in level were observed in intrahepatic obstructive jaundice and were probably due to a non-specific effect of prednisolone. In the latter condition norethandrolone therapy was often associated with high levels.

In an effort to identify proteins involved in the disease process of acute liver failure (ALF), we investigated changes in the plasma proteome associated with d-galactosamine/lipopolysaccharide (GalN/LPS) treatment of BALB/c mice. The plasma samples from mice with ALF and control were screened for potential differences using two-dimensional electrophoresis followed by liquid chromatography-electrospray ionization-tandem mass spectrometry or matrix associated laser desorption ionization-time-of-flight mass spectrometry. The expression levels of candidate protein named phosphatidylethanolamine binding protein (PEBP) in plasma and liver, brain tissues were confirmed by western blot and RT-PCR analyses. Results were confirmed in plasma samples of human beings. Seven proteins existed in plasma of GalN/LPS-treatment animals only but not in controls. They included PEBP, regucalcin, Cu/Zn superoxide dismutase, glyoxalase 1, malate dehydrogenase, proteasome subunit alpha type 1, and HPMS haptoglobin precursor. Two proteins, proteasome subunit alpha type 5 and apolipoprotein A-I precursor, were up-regulated by GalN/LPS, and one protein, HPMS haptoglobin precursor, was down-regulated by this treatment. Western blot analysis confirmed the results that PEBP protein levels increased significantly in plasma and liver tissues only in ALF mice, but not in surviving mice treated with GalN/LPS. Further analysis revealed that GalN/LPS also induced up-regulation of PEBP mRNA levels in liver tissues. Importantly, plasma obtained from ALF patients, but not from healthy volunteers or from hepatitis patients, also contained detectable levels of PEBP. The present study show that PEBP may be a potential plasma biomarker for ALF diagnosis and participate in the pathphysiological process of ALF.

Human cytomegalovirus (HCMV) is a widespread pathogen, the most common congenital viral infection, and the leading cause of infant hepatitis syndrome. In this study, serum samples were collected from 20 HCMV-infected infants with hepatitis and 25 controls. Of the 25 infants in the control group, 5 were infected with HCMV but without hepatitis, 10 had hepatitis but no HCMV infection, and 10 were healthy. Proteomic expression in the serum was detected by WCX2 chips and surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS), to identify serum protein biomarkers in infants with hepatitis syndrome resulting from HCMV. Fifteen protein peaks were distinctly different among the four groups in the mass range from 2,000 to 20,000 Da. Of these 15 peaks, 4 at 4,349.8, 5,808.7, 7,935.6, and 8,885.9 Da were significantly different between the congenital HCMV-infected infants with hepatitis and the controls. Five peaks were distinctly up-regulated in the infants with HCMV infection (3,266.8, 5,638.5, 5,909.1, 7,771.4, and 15,835.6 Da) compared to those without HCMV infection. Two proteins at 4,600.1 and 5,704.3 were up-regulated in infants with HMCV infection but no hepatitis. Four protein peaks were markedly different (7,567.0, 13,744.8, 15,100.7, and 15,915.0 Da) between the infants with hepatitis and the other controls. Comparison of the differentially expressed proteins' properties with those available on an international database suggest that specific serum proteins such as the augmenter of liver regeneration, pre-albumin, and haptoglobin closely related to liver function, and cytokines such as beta-defensins 31 and 8, and macrophage-derived chemokine, among others, are involved in HMCV infection and the pathogenesis of HMCV-induced hepatitis in infants.
