Serial assays for immunoglobulin M antibody to hepatitis B core antigen (IgM anti-HBc) were performed in 51 patients with antibody to hepatitis B e antigen (anti-HBe) in their sera. IgM anti-HBc was detected periodically and persistently in 8 (53%) of 15 patients with chronic hepatitis whose serum glutamic pyruvic transaminase (GPT) levels were elevated and was not detected in 36 patients with normal serum GPT levels. Antibody to delta agent was not detected in any of the patients. Of the eight patients positive for IgM anti-HBc, four had a high titer of IgM anti-HBc and either developed liver cirrhosis (three cases) or died due to massive hepatic necrosis (one case); the other four showed a low level of IgM anti-HBc and either recovered (two cases) or developed chronic persistent hepatitis (two cases). Of seven patients negative for IgM anti-Hbc, two had a fatty liver, and five, who had a history of blood transfusion, had chronic hepatitis. Thus, even though anti-HBe may be present, if the titer of IgM anti-HBc is high, the histological activity can be expected to increase, and the prognosis will be poor. If the titer of IgM anti-HBc is low, the histological activity may be expected to decrease, and the prognosis may be good. In patients with abnormally high serum GPT but without IgM anti-HBc, another type of hepatitis or a secondary form of liver disease should be considered.

Serum N-terminal procollagen type III peptide (sPIIIP) levels were evaluated in 58 patients affected by chronic liver disease, in order to assess the usefulness of sPIIIP as a marker of hepatic fibrosis. In 45 patients sPIIIP was also correlated to liver histology; biopsies were scored by two of the authors, without knowledge of diagnosis. Compared to normal controls, sPIIIP concentration was found to be significantly elevated in chronic active hepatitis (CAH) and in cirrhosis, but not in fatty liver. Patients affected by chronic persistent hepatitis (CPH) had values of sPIIIP higher than normal in four of 11 cases considered. A close correlation was found between sPIIIP values and histological parameters of inflammation, necrosis, and degeneration, while the relationship between sPIIIP levels and fibrosis was weaker. These data suggest that sPIIIP determination may reflect the extent of inflammatory changes in the liver; but it cannot be considered a reliable index of hepatic fibrosis.

1000 consecutive blood donors had their liver functions studied. 110 donors (11%) were found to have raised ALT of more than twice normal levels. 29 donors had liver biopsies done. Histologically 23 had fatty change, 5 had chronic persistent hepatitis and 1 had liver cirrhosis. Fourteen out of the 23 donors with fatty change also had hypercholesterolemia and hypertriglyceridemia. Viral serology of the 110 donors showed that 3 donors were HBsAg positive, 5 donors were Anti-HAV (IgM) positive and 20 donors were Anti-HBc (IgM) positive. Majority of donors with raised ALT had fatty liver on biopsy with only 6 donors having significant findings of chronic persistent hepatitis and cirrhosis. Serologically, most of the donors (74.5%) with raised ALT had no markers of Hepatitis A, Hepatitis B, CMV or EBV. An interesting finding is the high incidence (18%) of positive, Anti HBc (IgM) in donors with raised ALT.

In search of a practical biochemical test that will reflect hepatic steatosis, we assessed the significance of serum cholinesterase activity in 48 patients with nonalcoholic fatty liver, 16 obese subjects without fatty liver, 30 cases of chronic persistent hepatitis, 38 cases of chronic active hepatitis, and 20 cases of liver cirrhosis. Increased cholinesterase activity was observed in nonobese as well as obese patients with fatty liver, whereas obese subjects without fatty liver showed levels in the upper normal range. When we set a cutoff level above the upper normal limit, half of the patients with fatty liver showed values above it, with only a few overlaps with other patients. When obese patients with fatty liver took a low-caloric diet, cholinesterase activity decreased, clearly reflecting improvement of hepatic steatosis. Thus, measurement of cholinesterase activity is of diagnostic value and an alternative to computed tomography in hepatic steatosis, and will provide a practical measure for the assessment of effects during follow-up.

An enzyme-linked immunosorbent assay was developed to detect insoluble liver cell membrane antigen (LMAg) which gives rise to serum LMA (anti-LM) in HBsAg-negative patients. The optical density (OD) ratio of the average LMAg level of normal subjects was less than 1.2. In HBsAg-positive cases, high LMAg levels (OD ratio greater than 2.4) were noted in 8 of 8 patients with acute hepatitis (AH), 3 of 8 with chronic persistent hepatitis (CPH), 5 of 10 with moderate chronic aggressive hepatitis (CAH), 7 of 10 severe CAH and 4 of 8 with liver cirrhosis (LC). In HBsAg-negative cases, however, high LMAg levels were noted in only 6 of 8 patients with AH, 1 of 10 with CPH, 1 of 10 with moderate CAH, 1 of of 10 with severe CAH, 0 of 8 with LC, 0 of 8 with fatty liver and 5 of 10 with alcoholic hepatitis. In micro-immunodiffusion experiments, intensively absorbed rabbit anti-rat LM precipitated two organ-specific components of rat liver homogenate, one of which was identical to liver specific protein (LSP). In immunohistochemical demonstrations of LMAg and LSP, anti-LM, prepared from the serum of a HBsAg-negative CAH patient, bound to both human and rat acetone-fixed liver cell membranes, but not to those of human or rat kidneys. Absorbed rabbit anti-rat LM also bound to liver cell membranes, but absorbed anti-rat LSP lacked organ-specificity when assayed with the immunofluorescence technique using acetone-fixed liver sections. In conclusion, the appearance of serum LMAg was associated with high-SGPT patients and HBsAg-positive CAH patients.

Serum guanase activity was measured in 20 healthy adults and in 62 patients with acute viral hepatitis, chronic active hepatitis, chronic persistent hepatitis, liver cirrhosis and fatty liver. Guanase and gamma-GT in patients were elevated in 87 and 64%, respectively. Elevated guanase activities were found in most cases of acute viral hepatitis, as well as in chronic hepatopathies. In patients with acute viral hepatitis pathologic activities of guanase were found following partial or total normalization of other liver function tests.

Serum levels of TSH, thyroxine-binding globulin (TBG), T4, T3 and reverse T3 (rT3) were measured in 36 patients with fatty liver disease, 11 patients wih chronic persistent hepatitis, 17 patients with chronic active hepatitis, and 29 patients with liver cirrhosis. TBG was significantly above normal levels in both groups of chronic hepatitis, the slight concomitant T4 and T3 increase was significant only for T4 in chronic persistent hepatitis. A significant decrease in T4 and T3 concentration was found in fatty liver disease and in hepatic cirrhosis. A shift in T4 conversion to rT3 could exclusively be demonstrated for the group of hepatic cirrhosis, reflected by a significant increase in rT3. As our findings indicate normal TSH levels and a lack of clinical signs of hypothyroidism in chronic liver disease, the possibility of diverse regulating changes must be considered.

Serum angiotensin-converting enzyme activity was measured in various diseases of the liver. Activity increased in progressive order in patients with chronic persistent hepatitis, chronic aggressive hepatitis, and liver cirrhosis. Activity was increased also in patients with acute hepatitis. On the other hand, patients with fatty liver had normal angiotensin-converting enzyme activity and patients with extrahepatic obstructive jaundice showed subnormal activity. Although the mechanism for these enzymatic changes in diseases of the liver remains to be elucidated, serum angiotensin-converting enzyme determination may be useful in the diagnosis of diseases of the liver under certain conditions.

The presence of serological markers of hepatitis B virus (HBV) infection and of hepatocellular HBV DNA were investigated in 19 HBsAg-negative patients with clinically and histologically significant chronic liver disease. Four cases negative for antibodies to HBsAg (anti-HBs), to the core antigen (anti-HBc), and to the e antigen (anti-HBe) were classified as non-A, non-B hepatitis. The remainder, positive for one or more of the three antibodies, were classified as hepatitis B. Histologic diagnosis was chronic active hepatitis in five, chronic persistent hepatitis in 11, micronodular cirrhosis in two, and fatty liver in one patient. The DNA extracted from limited amounts of liver biopsies, without cleavage by restriction endonucleases, was analyzed by the Southern blot technique for the presence of episomal HBV DNA. Autoradiographs showed a single band of less than 4.0 kilobase (kb) corresponding to the monomeric form of HBV DNA in five patients, several bands of larger forms (4.0 to 18.0 kb) in three patients, both the monomeric and the larger forms in eight patients, and no HBV DNA in three patients. While HBV DNA was detected in the hepatocellular DNA of six patients who underwent splenectomy, hybridization was negative with the DNA extracted from their spleens. The episomal viral DNA larger than 4.0 kb may represent concatemeric forms or free oligomers which could not be distinguished from rearranged and/or integrated viral DNA in the limited analyses of the hepatocellular DNA hydrolyzed with HindIII or EcoRI. Our observations suggest the presence of HBV-like agents in the liver of serologically HBsAg-negative patients with chronic liver disease.

In two prospective studies including 962 patients and one retrospective study including 165 patients the problem was investigated, to what extend ultrasonography might change the diagnostic value of clinical examination, peritoneoscopy, guided liver biopsy and blind liver biopsy. It turned out, that liver biopsy is the method of choice in diffuse-parenchymatous disease (e.g. chronic active hepatitis, chronic persistent hepatitis, fatty liver), whereas laparoscopy is to be preferred if focal lesions (e.g. liver carcinoma) are present. Diffuse liver disease was present in 80% of the cases investigated; in this group of patients the diagnostic value of blind biopsy is equivalent to the diagnostic value of guided biopsy. Thus, blind biopsy does yield satisfactory results in most patients if it is possible to differentiate between diffuse and focal disease by ultrasonography. Such differentiation could be achieved in 77-98% of our cases, thus ultrasonography could intake a decrease in numbers of peritoneoscopies and an increase of blind liver biopsy.
