The specific activity of coumarin-7-hydroxylase was measured in liver microsomes from normal subjects and patients with liver disease. Liver specimens were obtained by needle biopsy and the microsomal fraction was separated by differential centrifugation. Its freedom from mitochondria was demonstrated by the absence of succinic dehydrogenase, a marker enzyme for mitochondria. Liver from healthy subjects showed variation in the specific activity of coumarin-7-hydroxylase from 0.16 to 0.65 nmol-mg-1-min-1, which is probably due to genetic factors. Patients with cirrhosis of the liver, chronic fatty hepatitis (chronic alcoholic hepatitis) and chronic active hepatitis showed a significantly lower mean hydroxylase activity. There was no significant difference in the mean level of hydroxylase between patients with subacute viral hepatitis or chronic persistent hepatitis and the normal controls.

To document the sequelae of acute hepatitis among recipients of commercial and volunteer blood and to assess factors influencing the development of chronic hepatitis (CH), 47 patients with post-transfusion hepatitis were followed prospectively from the time they received their transfusions. Twenty-nine had prolongation of at least 2-fold serum glutamic pyruvic transaminase (T) elevations for more than 20 weeks, and were classified as CH. When the patients with CH were compared to those with only acute hepatitis (abnormal T for less that 20 weeks), no difference was found with respect to age, sex, number of units transfused, incubation period, presence or absence of symptoms, occurrence of jaundice, maximum T, receipt or development of hepatitis B surface antigen or antibody, underlying illness, or area of the hospital where the patient was treated. Liver biopsies in 15 of the 29 revealed chronic-active hepatitis in 9, chronic persistent hepatitis in 2, unresolved hepatitis in 4. Five of the 9 patients with chronic active hepatitis were without symptoms. None of these died or have developed cirrhosis. Because chronic liver disease frequently developed after acute post-transfusion hepatitis among multiply transfused hepatitis B surface antigen negative blood recipients, close follow-up, including liver biopsy, is warranted in such patients with prolonged transaminase elevations.

Patients with chronic liver disease were tested for delayed hypersensitivity to the outer and the inner membranes of mitochondria (OMM and IMM) and the insoluble hepatocyte-surface membranes (IHSM), prepared from rat livers, by means of leucocyte migration inhibition technique. Positive reaction to OMM was found in 37% of patients with chronic persistent hepatitis and 35% of those with chronic active hepatitis and 43% of those with liver cirrhosis (P less than 0-05). That to IMM was 55%, 43% and 36% (P less than 0-05) and to IHSM was 37%, 47% and 45% respectively (P less than 0-05). IHSM was found to contain liver-specific components and patients with positive response to IHSM did not reveal at all a positive reaction to rat renal cell-surface membranes. The incidence of positive response to IHSM was significantly higher (54-2%) in patients with the present or previous infection with HBAg than in HBAg-non-infected patients (21-4%) (P less than 0-05). And there seemed to be a good correlation between a degree of cellular response to purified HBsAg and that to IHSM in these HBAg-infected patients. No correlation, however, was found between that to purified HBsAg and that to OMM or IMM in the same patients. This suggested that the cellular response to either HBsAg or IHSM, both related closely, may play a role in the perpetuation of chronic liver disease.

Radioisotope studies of iron kinetics carried out in patients with chronic hepatitis yielded the following results. Serum iron level and free iron binding capacity showed little difference from the normal mean value. All three types studied (chronic persistent hepatitis, chronic active hepatitis, chronic active hepatitis with cirrhosis) revealed an abnormal distribution of iron in the first 24 hours. Normalization of iron distribution ensued in persistent hepatitis and in chronic active hepatitis with cirrhosis, but in chronic active hepatitis the abnormal distribution persisted, as reflected by a decreased iron utilization and an increased iron storage in the liver. The cause of this is attributed to a transitory accumulation of ferritin in the liver.

The preliminary results of the HB, Ag and HBs Ab assay, performed with radioimmunological techniques in 31 cases of chronic hepatitis, 13 of whom carriers of chronic aggressive hepatitis (C.A.H.), 9 of chronic persistent hepatitis (C.P.H.) and 9 of cryptogenetic hepatic cirrhosis (C.H.C.) of both sexes, are reported. The highest number of HBs Ag positive cases was observed both in C.A.H. (69%) and C.H.C. (55%); very lower the HBs Ag positivity both in C.A.H. (33%) and C.H.C. (33%). No correlation between HBs Ag positive and HBs Ab positive was observed.

Serum samples from 103 HBsAg positive and 69 negative patients were examined in Ouchterlony double diffusion in agarose for the presence of e antigen and anti-e antibody. e antigen was found in 66% of the cases of active chronic hepatitis, 18% of those of active cirrhosis, and 12% of those of acute hepatitis. Anti-e antibody was found only in asymptomatic chronic carriers; it occurred in 56% of HBsAg-positive individuals with normal livers at biopsy. No e reactivity was found in 6 subjects with inactive disease and in 3 with chronic persistent hepatitis. The e system seems a valuable diagnostic tool utilizing the presence of the antigen to differentiate patients with chronic progressive disease from healthy carriers who, in contrast, often have circulating anti-e antibodies; its clinical value, however, is at present limited by the low sensitivity of the technique used for antigen detection. A significant association between e antigen and the intrahepatic expression of the core determinant of the HB virus was observed inthis study, suggesting they have a similar role in pathogenicity and infectivity; the association between anti-e antibody and HBsAg appeared uncertain, HBsAg being present in the liver irrespective of e reactivity.

Serum cholesterol, triglyceride, total lipids and the lipoprotein pattern were studied in 169 cases chronic liver disease confirmed by biopsy. On the ground of the immunological and morphological results the patients were classified into five groups. In chronic persistent hepatitis no significant abnormality was found. In chronic aggressive hepatitis and in cirrhosis of the liver the serum cholesterol level was significantly reduced. In fatty infiltration of the liver the serum cholesterol, triglyceride and total lipid concentrations were significantly increased, as compared with the normal values and with the figures obtained in the cases of chronic inflammatory liver disease. In the cases of cirrhosis with additional diabetes the lipid values were likewise increased. In chronic aggressive hepatitis and in cirrhosis of the liver the levels of pre-beta and alpha lipoprotein were decreased, in fatty infiltration of the liver those of beta and pre-beta lipoprotein were increased.

Chronic hepatitis was diagnosed on the basis of biochemical, immunological and morphological criteria in 153 cases. On the evidence of observations for a mean period of four years the prognosis of chronic persistent hepatitis is regarded as favourable, no progression to chronic aggressive hepatitis or to cirrhosis having been observed in any of the cases. On the other hand, chronic aggressive hepatitis was found to progress to cirrhosis in 12 out of 65 cases. Cirrhotic transformation was more frequent in hyperactive processes (8 out of 25 cases). The sera of patients with primary hepatocellular carcinoma showed low immunoglobulin concentrations, with increased coeruloplasmin and reduced transferrin levels.

Eight male subjects who were initially studied in 1972 with liver biopsy because of HBsAg carrier status were re-studied two years later with liver biopsy, clinical examination and standard liver function tests. Three of the eight subjects remained antigen positive and had continuing liver disease, this being either chronic active hepatitis or chronic persistent hepatitis. two subjects became HBsAg negative and their liver biopsies returned to normal. One subject became HBsAg negative but his biopsy disclosed chronic active hepatitis with cirrhosis in the presence of normal liver function tests. While persistence of the antigenaemia is associated with persisting liver disease, the converse is not true in that the disappearance of the antigen does not necessarily imply an improvement in liver disease. Liver biopsy remains the only reliable means of assessing liver disease as biochemical tests of liver function and the clinical findings may be of little value.

Sera of altogether 282 patients with different forms of hepatitis and cirrhosis were screened for cold reacting complement dependant auto-lympho-cytotoxins (CoCoCy). These antibodies are 19S-IgM-immunoglobins and have no HLA-antigen-specificity. CoCoCy occurred in 48% of the patients with chronic aggressive hepatitis (CAH), in 14% of the patients with chronic persistent hepatitis (CPH) and in intermediate rates in the sera of patients with acute hepatitis. No correlations was found between CoCoCy and hepatitis B-antigen (HB-Ag). CoCoCy could be demonstrated also in 20% of the sera of a HB-Ag-positive and in 6% of a HB-Ag-negative control group. The serum concentration of CoCoCy is low. CoCoCy seems to be of T-cell-specificity and to reflect the overall-immunoreactivity without relation to the specificity of the antigenic stimulus. Thus demonstration of CoCoCy may be of pathogeneic and pathodynamic rather than of diagnostic interest.
