20 coagulation parameters were investigated in 144 patients with different liver diseases. The groups of acute hepatitis, chronic active hepatitis and liver cirrhosis were compared and the prognostic value of the coagulation analyses investigated. It is clear that the determination of the factor V activity is a good and easy test for detection of actual liver function. Repeated controls over several weeks revealed with a statistical significance (p less than 0.0005) that all patients with a factor XIII below 35% and a plasminogen below 19% will die in liver coma, if they have not died beforehand from acute gastrointestinal haemorrhage, acute infection or cardiac arrest. Plasminogen is also lower in the group of non-survivors but the values of the two groups are overlapping and of no prognostic help in a single case. The possible causes of the diminution of factor XIII activity are discussed.

Antipyrine half-life (AP t1/2) was measured in 62 patients with, and 10 control patients without, liver disease to ascertain possible factors which may be useful in identifying patients with abnormal drug metabolism. Antipyrine metabolism was normal or marginally impaired in patients with compensated cirrhosis or acute hepatitis, whereas it was frequently abnormal in those with chronic active hepatitis or advanced alcoholic liver disease. A high degree of correlation was found among AP t1/2 and prothrombin time, hepatic encephalopathy, and ascites. Of patients with severely impaired drug metabolism, 80% had one or more of these features. The severity of histological changes in liver biopsies was of additional help in predicting impaired drug metabolism. Concurrent drug ingestion enhanced antipyrine metabolism in most patients with liver disease as well as in control patients. Inadequate diet was associated with prolongation of AP t1/2, but other environmental factors such as alcohol ingestion, cigarette smoking, and coffee consumption did not affect rates of drug metabolism in patients with liver disease. Consideration of all of the above factors allows qualitative predictions of the rate of hepatic drug metabolism in patients with liver disease, as assessed by the AP t1/2.

To determine the clinical significance of serum bile acid measurements, changes in the serum bile acid composition in liver diseases and endogenous bile acid clearance due to test meal loads were investigated. In the case of changes in the serum bile acid composition, a characteristic pattern of a remarkable increase of chenodeoxycholic acid (CDCA) was found in fulminant hepatitis. In patients with acute hepatitis, increases in CDCA were somewhat greater than those of cholic acid (CA) and there was tendency for these changes to precede changes in other liver function tests. In cases of extrahepatic obstructive jaundice, the CA/CDCA ratio was a large value exceeding 1.0. In investigations of endogenous bile acid clearance, serum bile acid concentration two hours after the text meal load clearly reflected the hepatic disorder and it was useful in differentiating between active and inactive form in chronic hepatitis and compensation and decompensation in liver cirrhosis.

Chronic hepatitis was diagnosed on liver biopsy of 76 patients; 52 (68%)had HBsAg. Of the 52 patients with HBsAg, 23% had HBsAg shown by immunofluorescence on the liver, while it could not be detected with radioimmunoassay on the serum; 77% had HBsAg detectable in liver and in serum, and none had HBsAg in serum only. HBsAg was detected more frequently in chronic aggressive hepatitis and active cirrhosis than in chronic persistent hepatitis and cirrhosis with little activity. No correlation was found in the different forms of chronic hepatitis between the HBsAg status on the one hand, and levels of transaminases, gammaglobulins, and auto-antibodies on the other. Acute hepatitis was diagnosed on liver biopsy of 24 patients; 50% had HBsAg. Liver tissue positivity was very low in the fully developed stage compared to serum positivity. In 146 patients with other liver ailments, both liver and serum were negative for HBsAg.

One hundred liver biopsies from 100 hepatitis patients were examined by the indirect immunofluorescent technique for the detection of HBsAg. Of the 60 positive specimens 52 were diagnosed as various types of chronic hepatitis and 8 were acute hepatitis. Four main distribution patterns of HBsAg were obtained: full cytoplasmic fluorescence with diffuse lobular distribution; cytoplasmic fluorescence with spotty distribution; peripheral fluorescence in the cell membrane and/or cell peripheries; and focal cytoplasmic positivity. There was an inverse relationship between the number of positive hepatocytes and the extent of liver cell necrosis. The distribution patterns of HBsAg were distinctive in each type of chronic hepatitis and in acute hepatitis. Homogeneous full cytoplasmic fluorescence, distributed diffusely in the whole liver lobule, was observed in chronic persistent hepatitis and in cirrhosis with little activity whereas peripheral liver cell membrane and/or peripheral cytoplasmic fluorescence associated with cytoplasmic positivity in a smaller number of hepatocytes was a characteristic finding in chronic aggressive hepatitis, active cirrhosis, and acute hepatitis with possible transition to chronicity. Focal cytoplasmic fluorescence was observed in acute hepatitis and a group of biopsies in chronic hepatitis in which HBsAg was detected in the liver but no antigen was detectable in the serum. The results show that the different patterns of distribution of HBsAg in the liver biopsy are helpful for the histological diagnosis of different types of HBAg positive viral hepatitis and are consistent with the hypothesis of the role of specific immune response in the pathogenesis of type B viral hepatitis.

This paper describes immunofluorescence studies on liver cell surface localization of hepatitis B surface antigen (HBsAg) and of IgG in acute and chronic hepatitis and in cirrhosis. In acute hepatitis B, HBsAg was found at the surface of hepatocytes in an early phase of the disease, but not during the recovery. This finding is consistent with the hypothesis that immune reactions to HBsAg may be responsible for the liver cell lysis. In HBsAg-positive chronic hepatitis and cirrhosis the antigen was found in the cytoplasm, but not on the surface of the hepatocytes, while in HBsAg-negative cases the antigen could not be detected in the liver cells. Both in HBsAg-positive and in HBsAg-negative chronic active hepatitis (CAH) and cryptogenic cirrhosis IgG bound to the membrane of the hepatocytes could be detected, suggesting a role of antibodies in the pathogenesis of the disease.

The incidence of HBAg in viral hepatitis, in chronic active hepatitis and in cirrhosis has been investigated by using immunological methods and a solid-phase radioimmunoassay. RIA demonstrated as positive: 90% of 20 patients with posttransfusion hepatitis; 88% of 50 patients with acute viral hepatitis; 100% of 13 patients with chronic active hepatitis and 35% of 20 patients with cirrhosis; whereas the frequency of HBAg in the same patients appeared to be lower by AGD, CIEP and CF. The measure of antigenaemia has been obtained by use of HBAg (ad) dose response standard curve. The quantitative HBAg data of an eight-week follow-up of fully recovered 15 patients with acute hepatitis are reported. In the first week it appeared a distribution of the HBAg levels into three classes of values. The concentration of HBAg in the serum became lower week by week and in 8th week the antigen was no longer detectable. The radioimmunoquantitation of HBAg in the serum of patients suffering from chronic acitve hepatitis and cirrhosis showed wide levels of antigenaemia ranging between 17 and 5100 ng ad equivalent/ml. The use of a dose response standard curve in order to quantify HBAg in the serum represents a further increased sensitivity of RIA.

Monomeric IgM could be found rather frequently in acute hepatitis and chronic aggressive hepatitis and occasionally also in chronic persistent hepatitis. Earlier it was reported in lympho-proliferative-, autoimmune diseases, some infectious diseases and in cirrhosis of the liver. The occurence of monomeric IgM in chronic aggressive hepatitis correlates with the detection of several autoantibodies (ANA, SMA, RF). The 7S-IgM-test may be used as an easily measurable additional criterium for diagnosis and course of chronic liver diseases.

Increased liver copper concentration and raised serum ceruloplasmin were demonstrated in primary biliary cirrhosis and disorders of the biliary tract, and occasionally in chronic active hepatitis and cirrhosis of the liver. Eight of 13 patients with primary biliary cirrhosis had liver copper content as high as seen in patients with hepatolenticular degeneration (is greater than 250 mjg/g dry weight). Normal liver content was found in patients with acute hepatitis, steatosis of the liver, hepatic amuloidosis, haemochromatosis, and Gilbert's syndrome. The urinary copper excretion was increased (is greater than 75 mjg/24 h) in half the patients with primary biliary cirrhosis and occasionally in the other patient groups. Serum ceruloplasmin was raised in more than half of all patients, and none had levels below the reference range. Raised heaptic copper content did not always coincide with enhanced urinary copper excretion, but was significantly correlated with this parameter and also with ceruloplasmin, alkaline phosphatases, and vitamin-K-dependent clotting factors, but not with ALAT. Combination of laboratory data, as found in typical cases of hepatolenticular degeneration, was not observed in this study, including 66 patients.

The serum immunoglobulin (Ig) G, A, and M levels were investigated with respect to their differential diagnostic significance, pathogenesis and estimation of prognosis of different forms of liver disease. The sera of 204 patients with acute hepatitis, fatty liver I and II, and cirrhosis, and of 110 healthy adutls were quantitatively determined for immunoglobulins. 1. IgG- and IgA-concentrations higher than 2000 mg% and 330 mg%, respectively, indicate chronic aggressive hepatitis or cirrhosis, and exclude all other groups. 2. A clear correlation between HBsAG (Australia Antigen) and immunoglobulin content could not be demonstrated in any group; 3. A significantly elevated level of IgA was observed in alcoholic cirrhosis when compared to non-alcoholic cirrhosis. No such differences were found inhe other groups. 4. Acute and chronic persistent hepatitis show a similar increase of immunoglobulins. Thus persistent high levels of Ig following acute hepatitis indicate the development into a chronic hepatitis. 5. A relative increase of IgA rather than IgG corresponds to the degree of inflammatory activity of a liver process.
