gamma-Glutamyl transpeptidase activity was measured in liver and serum from 110 patients undergoing diagnostic liver biopsy, including patients with alcoholic liver disease, fatty liver not due to alcohol, primary biliary cirrhosis, persistent hepatic disease, chronic active hepatitis and normal livers. Serum gamma-glutamyl transpeptidase was markedly elevated in patients with alcoholic liver disease and primary biliary cirrhosis while mean hepatic gamma-glutamyl transpeptidase activity was significantly increased only in the alcoholic liver disease group. There was considerable overlap of individual enzyme values among the different disease groups. There was no inhibitors or activators of liver gamma-glutamyl transpeptidase in any of these disorders. The increased liver activity was not related to the degree of hepatic fibrosis or cirrhosis. There was no correlation between hepatic and serum gamma-glutamyl transpeptidase activity. Hepatic and serum gamma activities were equally increased in individuals with alcoholic liver disease whether or not they were drinking at the time of the study. The data suggest that increased hepatic gamma-glutamyl transpeptidase activity is neither specific for alcoholic liver disease nor essential for serum GGTP to be elevated.

To evaluate the diagnostic significance of the collagen Type III (Col 1-3) N-terminal propeptide of procollagen Type III, with respect to activity and degree of liver fibrosis, Col 1-3 serum concentrations were measured in 111 patients with chronic liver diseases and in 60 patients were correlated with liver histology and morphometry. Col 1-3 was measured by a specific radioimmunoassay. Biopsies were read without knowledge of diagnosis. Periportal and intralobular lesions were assessed semiquantitatively by allocating 1 of 4 severity grades to each parameter. All portal areas were measured morphometrically. Compared to 27 normal controls, Col 1-3 concentrations were significantly elevated in patients with untreated chronic active hepatitis, cirrhosis and primary biliary cirrhosis, but not in chronic persistent hepatitis or fatty liver. Morphometrically measured portal tract area significantly correlated with Col 1-3 plasma levels. Among the semiquantitatively measured periportal lesions, the number of fibroblasts exhibited the closest relationship with Col 1-3 levels; there was no relationship between Col 1-3 levels and intralobular lesions. These data suggest that Col 1-3 serum levels reliably reflect the activity and degree of liver fibrosis and are useful along with liver biopsy in follow-up of patients with chronic liver disease.

Medroxyprogesterone acetate (MPA) elimination rate was investigated in 25 patients with primary biliary cirrhosis, alcoholic cirrhosis and fatty liver. The serum and urine concentrations of MPA were measured by RIA after a single oral administration of the drug. Biochemical liver tests and antipyrine kinetics were determined as indicators of the liver function. The antipyrine test, a reflector of the activity of hepatic drug-metabolizing enzyme system, was impaired only in alcoholics. The results demonstrate that the elimination rate of MPA is reduced in subjects with alcoholic cirrhosis, whereas the values of the patients with fatty liver and primary biliary cirrhosis are in the normal range. The findings show that the MPA elimination is impaired only in cases with far advanced liver disease.

The precision of CA 19-9 RIA kit was evaluated by recovery, reproducibility and dilution test with very satisfactory results. The CA 19-9 value in sera from 52 healthy individuals and from 224 patients with gastric intestinal cancer and other benign disease, showed an increased positive rate in several cases of gastric intestinal cancer. For example, the positive rate in pancreatic cancer, bile duct cancer, colo-rectal cancer, gastric cancer, esophagus cancer, primary biliary cirrhosis diabetes mellitus, liver cirrhosis and chronic hepatitis was 60%, 75%, 55.6%, 45.6%, 20%, 28.6%, 22.7%, 13.7% and 1.7% respectively. By contrast, values from patients with acute hepatitis, fulminant hepatitis, fatty liver, gastric duodenal ulcer, pancreatitis, and primary liver cancer were within the normal range. In this study, CA 19-9 RIA were found to be significant as an adjunct in the management of patients with gastrointestinal cancer, especially pancreatic cancer, and bile duct cancer.

Plasma, obtained just prior to diagnostic liver biopsy in 71 patients with various liver diseases, was examined by electroimmunoassay using immunoglobulin against human fibronectin and purified plasma fibronectin as standard. The plasma fibronectin concentration was not significantly different from age- and sex-matched healthy controls in patients with chronic persistent or chronic active hepatitis (n = 7), primary biliary cirrhosis (n = 8), alcoholic fatty liver (n = 9), alcoholic hepatitis (n = 10), and alcoholic cirrhosis (n = 16). Patients with acute viral hepatitis (type A (n = 2); type B (n = 7); type non A, non B (n = 1] had significantly (P less than 0.01) raised plasma fibronectin concentrations (median 506 mg/l (range 339-804] compared to controls (median 399 mg/l (range 304-462]. Morbidly obese patients with fatty liver (n = 11) had significantly (P less than 0.001) raised plasma fibronectin concentrations (median 610 mg/l (range 429-862] compared to controls (median 361 mg/l (range 303-419].

The serum concentrations of prealbumin, transferrin and immunoglobulins, as well as their concentration ratios, were determined in patients with fatty liver, alcoholic cirrhosis and primary biliary cirrhosis to evaluate the usefulness of these measurements in the differentiation between these diseases, and in the evaluation of the severity of the liver injury. Alcoholic cirrhosis was characterized by high IgA/prealbumin and IgG/prealbumin ratios, whereas in fatty liver these ratios remained normal or close to normal. The IgG concentration and the ratio of IgG/prealbumin were markedly higher in advanced than in early alcoholic cirrhosis, IgG/prealbumin being the most sensitive indicator. None of the assays reflected the degree of fatty degeneration. In primary biliary cirrhosis the mean IgG concentration was 93% higher than in alcoholic cirrhosis. One of ten patients with primary biliary cirrhosis had a normal IgM level, whereas 2 of 10 patients with alcoholic cirrhosis had a value above normal (greater than 2.9 g/l). IgM alone did not differentiate between alcoholic and primary biliary cirrhosis, while the ratio of IgA/IgM seems useful: a value over 2.0 was found in all patients with alcoholic cirrhosis but in none of those with primary biliary cirrhosis.

The authors report the case of a 32-year old woman admitted for hepatomegaly, weight loss, and moderate diarrhea. Liver function tests showed anicteric cholestasis with slight increase in serum level of transaminases. Liver biopsy demonstrated massive steatosis. Biological and radiological investigations of the small intestine showed a malabsorption pattern. Stool fat excretion was 54 g per day. Duodenal biopsies disclosed total villous atrophy. A ten-day treatment with metronidazole (1,5 g per day), followed by a gluten-free diet, resulted in rapid improvement of hepatic and intestinal symptoms. This case report shows that: 1) adult celiac disease may be the cause of severe steatosis; 2) anicteric cholestasis with or without hepatomegaly during the course of adult celiac disease may be secondary to steatosis, as well as primary biliary cirrhosis or malignant infiltration of the liver; 3) bacterial overgrowth should be searched and eventually treated in the case of massive fatty liver occurring in adult celiac disease.

We have measured antibodies to the enterobacterial common antigen (ECA) in sera of 86 patients with various liver diseases. ECA is a component of the cell wall of all enteric bacteria, and ECA antibodies are a specific indication of the presence of enterobacterial components. Patients with alcoholic cirrhosis with or without signs of alcoholic hepatitis had significantly raised anti-ECA titres compared with healthy control subjects. Other groups of patients (alcoholic hepatitis and/or fatty liver, primary biliary cirrhosis, chronic active hepatitis, or liver metastases) did not differ significantly from controls in the height of their anti-ECA titres. The results support the concept that Gram-negative bacterial components may have some role in the pathophysiology of alcoholic cirrhosis.

The medical records of 49 consecutive patients with primary biliary cirrhosis of the liver were screened for informations about medical examinations during the years before the diagnosis was established. In 15 cases previous medical reports could be found. Evidence of liver disease (slight elevation of transaminases and gamma-GT) was documented up to 18 years before the diagnosis was proven. In 6 patients liver biopsies had been performed: normal 1 x, fatty liver 1 x, fibrosis 1 x, non-specific hepatitis 1 x, chron. pers. Hep. 2 x. The characteristic increase of alkaline phosphatase often occurred within a few months. Antimitochondrial antibodies became positive independent of the beginning of cholestasis. It can be concluded that early stage primary biliary cirrhosis must be considered in patients with long standing slight elevation of liver enzymes even without cholestasis when other causes can be excluded.

Liver granulomas have long been known to pose diagnostic problems for pathologists; however, their prevalence and associated etiologic factors have not been studied in liver transplant patients. We reviewed 3632 liver biopsy specimens from 563 patients at two institutions and identified 42 patients with posttransplant granulomas. A possible or probable etiologic factor was identified in 30 (71%) cases. Most were epithelioid granulomas and microgranulomas located in the parenchyma associated with hepatocyte necrosis (21 cases, 50%). Portal-based granulomas were associated with recurrent primary biliary cirrhosis (5 cases, 12%), acute cellular rejection (2 cases, 4.8%), and a foreign body-type reaction (1 case, 2.4%). One case was associated with tuberculosis (2.4%), 4 cases occurred in a fatty liver (9.5%), and 8 patients had liver granulomas but no other significant abnormality. The granulomas were most frequent in the first 7 months after transplantation when the patients were biopsied more often and underwent episodes of rejection or acute hepatitis. Portal-based granulomas in this period were usually associated with acute cellular rejection. After 7 months, the frequency of granulomas as well as the number of biopsies decreased and portal-based granulomas associated with recurrent primary biliary cirrhosis were most common (5 cases, 12%). Rare, late-appearing parenchymal granulomas were also seen (3 cases) and consisted of 1 lipogranuloma and 2 cases of epithelioid granuloma. The latter were thought, in 1 patient, to be associated with parenchymal hepatocyte necrosis; the others were of unknown etiology.
