Using the single radial immunodiffusion method, the serum levels of IgG, IgA, Ig M, transferrin, haptoglobin, alpha2-macroglobulin, alpha1-antitrypsin and alpha1-acid glycoprotein were estimated in healthy subjects and patients with liver diseases consisting of chronic active and inactive hepatitis, incipient cirrhosis, cirrhosis and primary liver cancer. The results obtained from the statistical analysis of the data were as follows: i) Immunoglobulins and alpha2-macroglobulin in all diseases were higher than those of healthy subjects. ii) The increased transferrin levels were found in chronic active and inactive hepatitis, and the increased alpha1-antitrypsin levels were observed in chronic inactive hepatitis, in incipient cirrhosis in cirrhosis and in primary liver cancer was higher than those of the other liver diseases. iii) Haptoglobulin levels in all diseases except for chronic inactive hepatitis were decreased. iv) alpha1-acid glycoprotein in chronic active hepatitis, in incipient cirrhosis and in cirrhosis were lower than that of healthy subjects. The evaluation of significance for difference of each protein level among disease groups clarified that the decrease of haptoglobin in cirrhosis and the increase of alpha1-antitrypsin in primary liver cancer were characteristic change respectively.

A new method, radio-crossed immunoelectrophoresis, demonstrates alpha-fetoprotein (AFP) in sera with a sensitivity of 1 mug/1. By this method AFP with alpha mobility was not found in sera from healthy individuals, patients with chronic active hepatitis and cirrhosis, primary biliary cirrhosis, secondary liver cancer and cystic fibrosis. In some of the sera, AFP was elevated when measured by conventional radioimmunoassay method and the sera contained an AFP-like substance with gamma mobility when analyzed by radio-crossed immunoelectrophoresis. The nature of this gamma substance is still obscure and needs further investigation.

A 57 year old man with auto-immune chronic active hepatitis, regularly treated with immunosuppressive therapy, had hepatocellular carcinoma (HCC) 10 years after diagnosis of the hepatitis. Assays of the hepatitis C virus antibodies against capsid and non-structural proteins revealed seronegativity in serial serum samples of this patient stored in the previous 10 years during follow up. The seronegative hepatitis C antibodies excluded hepatitis C virus as the cause of the HCC. The occurrence of HCC in this case suggests the necessity of surveillance for early detection of liver cancer in patients with auto-immune chronic active hepatitis undergoing long-term immunosuppressive therapy.

Tissue plasminogen activator (t-PA) levels in plasma or serum were studied in 416 patients with liver diseases: acute hepatitis (AH, n = 30); fulminant hepatitis (FH, n = 36); chronic inactive hepatitis (CIH, n = 57); chronic active hepatitis (CAH, n = 39); compensated liver cirrhosis (cLC, n = 78); decompensated liver cirrhosis (dLC, n = 84); hepatocellular carcinoma (HCC, n = 64); advanced hepatocellular carcinoma (aHCC, n = 28); and compared with that of a control group (n = 106) of healthy subjects. The t-PA levels showed significant increase in patients with AH, FH, CAH, cLC, dLC and HCC, compared with normal controls. The abnormal rates in t-PA levels (higher than 8.3 ng/ml) for each type of liver diseases were 86.1% in FH, 46.2% in CAH, 50% in cLC, 85.7% in dLC, 67.2% in HCC, and 89.3% in aHCC. t-PA levels tended to be higher in more advanced liver diseases. t-PA levels significantly correlated positively with plasminogen activator inhibitor (PAI-1) in AH, cLC, dLC, HCC and aHCC, and negatively with plasmin alpha 1-plasmin inhibitor complex (PIC), plasminogen (Plg), FDP, AT III and alpha 2-plasmin inhibitor (alpha 2-PI) in dLC, prothrombin time (PT) and fibrinogen (Fbg) in HCC. t-PA levels in patients with FH, CAH and dLC were significantly higher than those in patients with AH, CIH and cLC, respectively. Moreover, the changes of t-PA levels in the clinical courses of various liver diseases revealed that t-PA levels increased sensitively with progression of liver diseases or in advanced liver diseases.(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence of antibodies to hepatitis C virus (HCV) was investigated in 129 patients with chronic liver disease (85 with chronic active hepatitis and 44 with cirrhosis) and 53 patients with hepatocellular carcinoma. The commercially available second generation anti-HCV enzyme immunoassay kit was used. Antibodies to hepatitis C virus were detected in 16.2% of the patients with chronic liver disease and in 15.1% with hepatocellular carcinoma. Of the HCV positive patients in all groups 51.7% were positive for hepatitis B virus (HBV) markers indicating present or past infection. Prevalence of HBV markers in all the three groups (CAH, cirrhosis and HCC) was higher as compared with anti-HCV prevalence. These results suggest that HCV infection may not be a major cause of chronic liver disease and hepatocellular carcinoma in India and indicate the presence of other aetiological agents.

PAP technique and rabbit anti-X serum were used to detect the X protein in tumor and nontumor liver tissues from 34 patients with HCC. The positive rate of the X protein in both tissues were 94.1% and 84.4% respectively. Of the 34 patients with HCC, 27 were complicated by liver cirrhosis, in whom 92.6% were X protein positive in liver cells. It was found that almost all of the liver cells adjacent to the tumor tissue showed strong positive staining. The high frequency and predominant expression of X protein in HCC and liver cirrhosis tissues indicated that X protein may play an important role in hepatocarcinogenesis. X protein was detected in 17.2% of the patients with CAH, which suggested the risk of transformation from CAH to cirrhosis and/or HCC. X protein was first found in bile duct epithelial cells in 59.4% of the patients with HCC, and 6 of 34 HCC were combined with bile duct carcinoma, and some cancer cells were found positive for X protein. It seems that X protein may also be a potential factor in the oncogenesis of bile duct carcinoma.

To study the relationship between duck hepatitis B virus (DHBV) infection and duck hepatocellular carcinoma (DHCC), histological examination and DHBV DNA hybridization were performed in 875 ducks from three flocks in Qidong County. Among them, 34 suffered from hepatoma, including 23 hepatocellular carcinoma, 8 cholangiocarcinoma and 3 hepatocellular-cholangiocarcinoma. Of the 34 ducks with hepatoma 27 were positive for DHBV DNA in the liver and/or serum. DHBV DNA was demonstrated in neoplastic nodules of 22 ducks. Southern blot analysis showed that 13 cases were of the integrated pattern of DHBV DNA in neoplastic nodules. The paratumor tissues of 14 ducks with massive tumor were analysed at the same time. Five cases showed integrated pattern, 4 cases free pattern and the other 4 cases both integration and free pattern of DHBV DNA. The hybridization pattern of DHBV DNA in tumor nodule was different from that in paratumor regions in 11 cases and identical in 3 cases. DHBV antigen was positive in 13 tumor nodules and 21 paratumor tissues in the 34 ducks with hepatic tumor by both victoria blue and orcein stain methods. Advanced liver diseases were found in 30 out of the 34 ducks with hepatoma, including 12 cirrhosis and 18 chronic active hepatitis. In southern blot analysis of 122 DHBV DNA positive Qidong ducks without hepatoma, only free pattern of DHBV was seen, while 44 control ducks from Changchun were negative for DHBV DNA. Neither hepatic tumor nor liver diseases were seen in the control ducks. The results suggest that hepatocellular carcinoma in ducks is similar to that in human HCC. They have a high frequency of viral DNA integrated into the host genome and a liver disease background.

To evaluate the role of IgM specific antibody in the diagnosis and monitoring of the patients with chronic hepatitis C, sera from 114 cases with chronic hepatitis C and liver cirrhosis were tested. IgM antibody to hepatitis C virus was detected in 40.0% of CAH, as compared with 21.4% of CIH, 17.4% of LC, 20.0% of LC with HCC. IgM antibody was also detectable in cases with high level of s-ALT. Patients with positive this antibody have high titer of IgG antibody to hepatitis C virus. In summary, testing for this antibody may be useful to evaluate the recurrence or disease activity and may also be helpful in IFN therapy.

Forty-nine liver disease patients (7 chronic persistent hepatitis, CPH; 10 chronic active hepatitis, CAH; 13 liver cirrhosis, LC; 9 primary hepatocellular carcinoma, PHC, without LC; and 10 PHC with associated LC) and 20 controls were assessed for their serum alpha-L-fucosidase (ALF) and alpha-fetoprotein (AFP) levels and several routine liver injury parameters. Tumor diameter in those with hepatic cancer was assessed by angio-CT. Only ALF and AFP were significantly greater in patients with PHC and PHC + LC patients as compared to patients with LC alone. At an accepted cutoff level of 500 ng/ml, the AFP level provided 43% false negative tests. On the other hand, an ALF level exceeding 740 mumol/hr/ml provided a sensitivity of 84% with a specificity of 94%. No relationship between the ALF level and Child's criteria or with any liver injury parameter was evident. Considering all individual values, the ALF, rather than the AFP, correlated with tumor size. This finding suggests the ALF level may be of value in the early detection of PHC as well as in the follow-up of patients treated for PHC.

The rate of micronucleus formation in lymphocytes was determined in 42 patients (including 10 acute icteric hepatitis B, 15 chronic active hepatitis B (CAH), 8 liver cirrhosis and 9 liver cancer) and 13 normal subjects. The results showed that the rate of micronucleus formation in lymphocytes in the patients with CAH (12.267 +/- 5.298%), liver cirrhosis (12.375 +/- 8.551%) or liver cancer (19.444 +/- 13.324%) was markedly higher than that in those with acute icteric hepatitis B (5.400 +/- 1.430%) or normal subjects (3.308 +/- 1.284%) (P less than 0.01). The rate of micronucleus formation in lymphocytes is higher in the liver cancer group than that in the CAH group or cirrhosis group (P less than 0.05). The rate of presence of two or more micronuclei in the lymphocytes was obviously higher in the liver cancer group (3.667 +/- 4.743%) than that in the liver cirrhosis group (1.500 +/- 1.690%), CAH group (1.467 +/- 1.807%), acute icteric hepatitis B group (0.600 +/- 1.075%) or healthy group (0.462 +/- 0.660%) (P less than 0.01 or less than 0.05). This method is much simpler than the measurement of chromosomal damage, and its reliability is as good as the latter. Measurement of micronuclei in lymphocytes can reflect the degree of liver damage in patients with the infection of hepatitis B virus. It may be used as the subclinical marker of the patients with liver cancer too.
