In a group of 205 patients with alcoholic diseases of liver the diagnostic relevance of biochemical tests (GOT, GPT, AP, GGTP, BSP) was reconsidered with discriminatory process (separation of diagnosis). The group contained 16 patients with nutritional-caused and 41 cases with alcoholic-caused fatty-infiltration of liver. 148 patients showed a toxic chronic liver disease; 52 a chronic hepatitis and 96 cirrhosis of liver. Laparoscopy and morphology guaranteed the clinical diagnosis and therefore the accuracy of biochemistry in separation of diagnosis was given. The biochemical tests were not able to offer a separation of fatty-infiltration with reference to cause, changes of the process in toxic hepatitis and cirrhosis were announced. Intersection in several cases was noticed and biochemical tests were not able to substitute endoscopy and morphology for clinical and diagnostic use in all cases. In every regard the enzyme-tests,--above mentioned--, and determination of sulfobromthalein are aptly to development of diseases and deficiency of alcohol.

In 131 patients on a medical service and 97 patients on a surgical service, in whom a diagnosis of hepatobiliary disease was verified in the hospital, the diagnostic value of routine liver tests performed soon after admission was evaluated by stepwise discriminant analysis. By measurements of alanine aminotransferase, alkaline phosphatases, gamma globulin, prothrombin time, bilirubin, and albumin, half of the medical patients were correctly classified into one of seven diagnostic categories. Aminotransferase contributed most to the classification, being twice as effective as random allocation. Decreasing the number of diagnostic categories to three (hepatitis, fatty liver, and chronic liver disease) increased the frequency of correct allocation to 80%. The allocation of all the patients to seven medical and four surgical diagnostic categories by means of four tests (aminotransferase, alkaline phosphatases, prothrombin time, and bilirubin) was significantly improved by each step with a misclassification rate of 55% when all tests were used. A reduction of the diagnostic groups to five (hepatitis, fatty liver, chronic liver disease, duct obstruction and tumor) increased the frequency of correct allocation to 63%. The analysis demonstrates the limited diagnostic effectiveness of routine liver tests when used alone. The absolute discrimination values depend on the a priori frequencies of the diagnostic groups investigated, and therefore may vary from time to time and from place to place.

A number of clinical, biochemical, immunological and morphological variables were recorded at first admission of 500 consecutive patients with biopsy verified acute viral hepatitis in the period February 1969-June 1972. In February 1973, 28 of these patients had a morphologically documented chronic liver disease: 4 cirrhosis of the liver, 15 chronic aggressive hepatitis, and 9 chronic persistent hepatitis. 74 patients were followed up until morphological normalization took place. The initially recorded variables in the two groups were compared, and the following factors were significantly higher in the group with subsequent development of chronic liver disease:--frequency of drug addicts, median of the highest gammaglobulin, ANA, SMA, partial destruction of the limiting membrane, incidence of piecemeal necrosis, and pronounced plasma cell infiltration in the portal tracts. These preliminary results suggest that factors in the initial phase of acute viral hepatitis can be helpful to some extent in predicting the course and prognosis of the disease.

Chronic liver disease developing after acute hepatitis type B is well documented, but is not thought to occur after acute hepatitis due to other viruses. However, follow-up of 29 patients in a haemodialysis unit who contracted HBsAg-negative acute hepatitis during 1968-70 revealed 8 cases with raised serum-aminotransferase levels dating from that time. Liver biopsy in 7 of these disclosed chronic aggressive hepatitis in 3, of whom 2 had already progressed to advanced cirrhosis. Chronic persistent hepatitis was present in 2 others, and the remaining 2 had non-specific hepatitis in association with massive iron overload. Immunological studies demonstrated a higher frequency of cellular immunity to HBsAg in those who had previously had acute hepatitis than in those who had not, although the prevalence of humoral antibody was similar in the two groups. One possible explanation for these findings is the presence of immunological cross-reaction at a cellular level between the hepatitis B virus and that responsible for the initial outbreak.

"e" is a serum antigen associated with type-B hepatitis. It is found only in hepatitis B surface antigen (HBsAg) positive sera, but is antigenically distinct from HBsAg. e antigen was not detected in the serum of any of 99 cases of acute type-B hepatitis who recovered normally. Its antibody, anti-e, was found in 14 (14%). The antibody usually appeared before clearance of HBsAg and before appearance of HBsAb. Serum e was not detected in any of 29 symptom-free carriers of HBsAg, but 21 (73%) showed anti-e. Serum e was found in chronic active hepatitis (44%) and chronic persistent hepatitis (31%). The antibody, however, was detected in only 2 of 79 patients with chronic active hepatitis but in 7 (44%) of chronic persistent hepatitis. Serum e was not found in 5 patients with primary liver-cell carcinoma or 5 with inactive HBsAg-positive cirrhosis. The antibody was, however, found in all 5 of those with inactive cirrhosis and in 4 of the 5 with primary cancer. These results suggest that the presence of e antigen is associated with active and usually continuing liver disease. Anti-e, however, is associated with inactive liver disease and asymptomatic carriage of HBsAg, and its presence must be regarded as a valuable sign in predicting those who will escape progressive chronic liver disease.

To examine the association between e antigen and hepatitis-B surface antigen (HBs Ag) we studied 90 inpatients with acute viral hepatitis type B. e Antigen was present in 24 of the patients; these patients had detectable levels of HBs Ag for significantly longer than the 66 with no e antigen in their serum. The HBs Ag subtypes D (adw) and Y (ayw) were similarly distributed among patients with e antigen and among those without, and no differences in the results of biochemical liver function tests were observed between the two groups during the acute phase of illness. Three of the five patients who developed clinical and histological signs of chronic liver disease were positive for e antigen, a finding which supports the hypothesis that e antigen has a prognostic value in hepatitis B.

The effect on abnormal coagulation tests of infusions of fresh-frozen plasma (F.F.P), prothrombin complex concentrates, and a combination of these treatments was compared in 30 patients with chronic liver disease undergoing needle biopsy. A single dose of F.F.P. (12 ml/kg body-weight) was found to be the least effective therapeutic regimen. The concentrate containing factors II, IX, and X was also not adequate, but the additional administration of factor-VII concentrate corrected the prothrombin-time (P.T.) and "Normotest" (N.T.) in most patients. However, this regimen did not correct the prolonged kaolin activated partial thromboplastin-time (K.P.T.T.). The results of tests for exploring both the extrinsic (P.T. and N.T.) and intrinsic (K.P.T.T.) coagulation systems only became normal after the combined administration of a lower dose of F.F.P. (8 ml/kg body-weight) and of both concentrates (12 units/ml). There was no clinical or laboratory evidence of thrombotic complications. No patient developed acute hepatitis or hepatitis-B surface antigen in the twelve months after biopsy. These results indicate that prothrombin-complex concentrates in combination with F.F.P. may therefore be used to allow liver biopsy to be performed safely in patients presenting with severe coagulation defects.

Progression of acute type B hepatitis to chronic liver disease and cirrhosis is well recognized, whereas no progression of acute type A hepatitis has as yet been documented. The natural history of acute non-A, non-B hepatitis has not been previously characterized. Ten cases of chronic liver disease were identified in 44 cases of acute non-A, non-B post-transfusion hepatitis. Age, sex, severity of acute illness, and prevalence of preoperative antibodies to known hepatitis-producing agents did not differ between the group whose hepatitis progressed to chronicity and the group whose hepatitis resolved. Less progression of acute hepatitis to chronic liver disease was seen in those patients receiving immune serum globulin preoperatively than in those receiving an albumin placebo (P = 0.009). Only 3 patients had clinical symptoms of hepatitis at the time of liver biopsy, and elevations of liver enzymes and gamma-globulin were mild. However, liver biopsy specimens in 8 of 10 patients showed chronic active hepatitis and an additional biopsy specimen showed cirrhosis. Acute non-A, non-B post-transfusion hepatitis often progresses to chronic active hepatitis. Preoperative gamma-globulin prophylaxis significantly reduces this progression. Identification and characterization of this viral agent(s) will further aid in the prevention of this undesirable complication of blood transfusion.

Using a radioimmunoassay technique serum alpha-fetoprotein could be detected in healthy adults in concentrations of less than 20 microgram/l. Of patients with acute, viral hepatitis 43% exhibited a transient rise of serum alpha-fetoprotein, the peak occurring eight to nine days after the maximum recorded serum aspartate transaminase activity. Patients with hepatic damage due to paracetamol poisoning were also shown to have transiently raised levels, the peak occurring earlier than in subjects with viral hepatitis. Six subjects with fatal fulminant hepatitis were studied; the three with the more protracted illness were noted to have increased levels before death. Twenty of 163 cases of chronic liver disease also had raised serum alpha-fetoprotein concentrations. In four, primary liver cell cancer developed; in two of these the serum alpha-fetoprotein levels rose progressively, and in two it remained raised but at low levels.

Serum samples from 94 Finnish hospital patients with hepatitis B were investigated for subtypes of HBsAg. Subtype ay predominated in patients with acute hepatitis (77%). All drug abusers had the ay subtype. Of 11 patients with chronic liver disease, 10 (91%) had the ad subtype. Five of 7 hepatitis cases associated with blood transfusion had subtype ay, although this determinant has not been detected among Finnish non-paid blood donors. These results suggest that blood donors who incubate hepatitis B (HBsAg not yet detectable) are an important source of transfusion hepatitis.
