This study was undertaken to evaluate the use of serum alpha 1-antitrypsin (alpha 1AT) in clinical diagnosis of primary hepatic carcinomas with monoclonal antibody-rate nephelometry. BALB/c mice were injected with human alpha 1AT. Spleen cells of the immunized mice and SP2/0 myeloma cells were hybridized in vitro. Monoclonal antibodies against alpha 1AT so obtained were used as detection agents in immuno-chemical monitor system (ICS). In 50 healthy individuals, serum alpha 1AT was 209 +/- 46.04 mg/dl. Serum alpha 1AT was determined in 49 patients with primary hepatic carcinoma, 26 with chronic active hepatitis and 26 with cirrhosis. Their positive rates were 43%, 3.8% and 0, respectively. Serum alpha 1AT level was significantly higher in primary hepatic carcinoma than in chronic active hepatitis and cirrhosis patients (P less than 0.001). No difference was found in alpha 1AT between patients with benign liver diseases and healthy adults (P greater than 0.05). The results indicate that alpha 1AT is useful in the diagnosis of primary hepatic carcinomas.

An immunohistochemical study on 63 hepatocellular carcinomas (HCC) was performed for the demonstration of alpha 1-antitrypsin (AAT), alpha-fetoprotein (AFP) and hepatitis B virus (HBV) antigens. AAT and AFP were also investigated in 54 cases of cirrhosis not associated with HCC. AAT was frequently expressed both in HCC (82.5%) and in cirrhosis (53.7%), whereas AFP was present in 41.2% of HCC and never detected in cirrhosis used as controls. These findings suggest that AFP is the more specific antigen for use as a marker of malignant cellular transformation. The HBsAg-positivity in 31.7% of HCC supports the hypothesis of a close link between virus B infection and the tumor.

We quantitated alpha 1-antitrypsin mRNA in normal, alpha 1-antitrypsin-deficient cirrhotic and biliary cirrhotic livers using two-dimensional electrophoretograms of [35S]methionine-labeled translational products of total hepatic RNA and RNA/DNA hybridization. alpha 1-Antitrypsin precursor product was identified by immunoprecipitation. The relative abundance of alpha 1-antitrypsin product from normal (0.989 +/- 0.197), cirrhotic (0.956 +/- 0.062) and alpha 1-antitrypsin deficient (0.818 +/- 0.12) livers was not significantly different. Although (RNA/DNA) was decreased in the PiZZ cirrhotic livers compared to normal (0.56 +/- 0.045 vs. 0.95 +/- 0.225), it equaled that found in the PiM cirrhotic livers (0.56 +/- 0.055). The concentration of alpha 1-antitrypsin mRNA [relative abundance X (RNA/DNA)], while decreased in PiZZ compared to normal liver, is thus no different in PiZZ cirrhotics than in PiM cirrhotics. We confirmed this observation by quantitation of the alpha 1-antitrypsin mRNA using an alpha 1-antitrypsin genomic probe. By RNA/DNA hybridization, alpha 1-antitrypsin mRNA was equal in PiM cirrhotic and PiZZ cirrhotic (38.48 +/- 4.5 vs. 31.93 +/- 2.1), but significantly decreased from noncirrhotic PiM liver (58.36 +/- 12.7). We conclude that alpha 1-antitrypsin mRNA is decreased in cirrhosis of any etiology, and this decrease appears to represent a general response of the liver to injury. Since the decreased alpha 1-antitrypsin mRNA in PiM cirrhotics is associated with normal serum alpha 1-antitrypsin levels, it is unlikely that the decreased alpha 1-antitrypsin mRNA in PiZZ cirrhotics accounts for their decreased serum levels.

Six acute phase proteins (haptoglobin, alpha 1-acid glycoprotein, alpha 1-antitrypsin, alpha 2-macroglobulin, C reactive protein and transferrin) have been measured in the sera of chronic liver disease (CLD) patients with different aetiology (viral, autoimmune and alcoholic) and histology (steatosis, chronic persistent hepatitis, chronic active hepatitis, cirrhosis), and in patients with liver cancer. 1) The most striking changes concerned alpha 2-macroglobulin (increased) and haptoglobin (decreased) levels. 2) Transferrin was lower in alcoholic liver disease than in viral CLD, CRP was lower in autoimmune than in viral or alcoholic CLD, and alpha 1-acid glycoprotein was lower in viral and alcoholic CLD than in autoimmune CLD. Acute phase protein assay may prove useful in differential diagnosis, particularly when specific markers are not available (autoimmune, non A, non B, alcoholic liver diseases). 3) No significant differences related to aetiology (B, non A non B, D viruses) were observed in viral CLD. 4) Patients who progressed to CLD after acute viral hepatitis type B or non A non B did not show different APP levels from those who had recovered when tested 8-12 months after the acute phase. 5) The pattern of APP changes observed in primary liver cell carcinoma was different from both the cirrhotic pattern and the pattern presented by other tumours with or without liver metastasis.

Serum alpha 1-antitrypsin, alpha 1-antichymotrypsin and alpha 2-macroglobulin increased significantly in patients suffering from liver diseases: hepatoma, amoebic liver abscess, hepatitis, hepatic cirrhosis, cholangiocarcinoma, carcinoma of the head of pancreas including liver fluke infection (opisthorchiasis). Marked increase of alpha 1-antitrypsin and alpha 1-antichymotrypsin were found in cholangiocarcinoma, carcinoma of the head of pancreas, amoebic liver abscess, hepatic cirrhosis and hepatoma. alpha 2-macroglobulin increased markedly in hepatic cirrhosis. The concentrations of protease inhibitors found in opisthorchiasis were only moderately elevated.

The blood concentrations of granulocytic elastase (PMN-E), alpha 1-antitrypsin and alpha 2-macroglobulin were examined to evaluate their clinical significance in patients who underwent hepatectomy due to liver cancer with liver cirrhosis (n = 31, Group A), due to liver cancer with chronic hepatitis (n = 5, Group B) and without hepatic complications (n = 6, Group C) and other major surgeries (n = 10, Group D). In all groups, on the first postoperative day, blood PMN-E increased rapidly more than three times of the preoperative levels. Despite a decreasing tendency from postoperative Day 3, the value in Group A reincreased on Day 5. The peak PMN-E values within 24 postoperative hours showed significant positive correlations (p less than 0.01) with the amounts of hemorrhage and blood transfusion during operation in all groups. Even in 18 cases without blood transfusion, peak PMN-E was positively correlated (p less than 0.05) with the operative time and the amount of blood loss during operation. In Group A, patients in whom blood PMN-E increased after postoperative Day 3 developed infection and adult respiratory distress syndrome. After temporary reduction after operation except for Group C, blood alpha 1-antitrypsin increased from postoperative Day 3. However, alpha 1-antitrypsin in Group A was significantly low (p less than 0.01), compared to the increased levels in Group C and D. Blood alpha 2-macroglobulin showed no tendency of postoperative increase in all groups.

In the light of recent findings concerning the importance of intermediate alpha 1-antitrypsin deficiency in the development of chronic liver disease and of hepatocellular carcinoma, we report the case of a 56-year-old woman affected by cirrhosis with significant features of liver cell dysplasia associated with intermediate alpha 1-antitrypsin deficiency (protease inhibitor SZ phenotype). In our paper we emphasize the importance of a precocious diagnosis and identification of individuals carrying the Z allele, also heterozygous.

Previous studies indicated decreased numbers and depressed clearance function of hepatic macrophages in alcoholic liver disease (ALD). We examined hepatic macrophages by immunohistochemical techniques in 45 liver biopsies from patients with a spectrum of ALD and compared them with 20 histologically normal biopsies from non-alcoholic patients. Antisera against lysozyme, alpha 1-antitrypsin (alpha 1AT) and a cytoplasmic molecule on macrophages (MAC-387) were used and the number of positively staining hepatic sinusoidal macrophages and portal tract macrophages assessed separately. Portal tract macrophage numbers were increased with all three markers in biopsies exhibiting only fatty change (P less than 0.05) and with MAC-387 in all ALD groups. In agreement with previous studies, lysozyme positive hepatic sinusoidal macrophages were decreased in all ALD groups. However, the other markers did not show any significant decrease and MAC-387 positive macrophages were increased in livers with cirrhosis plus hepatitis (P less than 0.01). The use of three markers revealed phenotypic heterogeneity of hepatic macrophages with antibodies to lysozyme and alpha 1 AT staining more hepatic sinusoidal macrophages than MAC-387, but MAC-387 and anti-lysozyme staining more portal tract macrophages than anti-alpha 1AT. Since hepatic macrophages appear to be heterogeneous and capable of diverse functions including the release of cytotoxic mediators, the finding of increased numbers, even in early ALD, suggests they may contribute to the increased numbers, even in early ALD, suggests they may contribute to the tissue damage.

During 1972-1974, 200,000 Swedish infants were screened for alpha 1-antitrypsin deficiency. Of 127 PiZ (Protease inhibitor) children followed from infancy to 12 years of age, four PiZ children with neonatal liver disease have died; two of liver cirrhosis, one was found to have liver cirrhosis at autopsy, having died of aplastic anemia and the fourth died in an accident. Liver microscopy showed a mild increase of periportal fibrous tissue. Another PiZ child died of anaphylactic shock. At 12 years of age, none of the PiZ children have clinical symptoms of liver disease. No PiZ-, PiSZ, PiS- or PiFZ child has had any clinical symptom of liver disease. One PiSZ child died of sudden infant death syndrome. Laboratory analyses from birth through 12 years of age have shown increased S-Bilirubin levels in 11% of the PiZ infants, which normalized within the first half year of life. S-GT was abnormal in about half of the infants, but had normalized when checked at 8 and 12 years of age in all but 6-3% of the PiZ children. The percentage of abnormal S-ALAT test results have decreased from 73% during the first year of life, to about 15% at the age of 12. The range of the abnormal levels also decreased considerably. Abnormal S-GT or S-ALAT levels were found in about 20% of the PiSZ infants, the proportion decreasing to 2% at the age of 12.

The chance coincidence of an X-linked disorder with an autosomal recessive disorder in one child is described. The child had the clinical phenotype of a mucopolysaccharidosis and the activity of iduronate sulphatase was almost absent. Furthermore, fibroblasts from a typical Hunter patient were unable to correct the patient's fibroblasts. However, three 24 h urine samples collected at 18-36 months of age showed a nearly normal excretion of acid mucopolysaccharides. The boy died in liver coma at 3 years of age. Autopsy showed cirrhosis of the liver and changes in liver tissue consistent with alpha 1-antitrypsin deficiency.
