(1) Passive hemagglutination and radioimmunoassay are suitable methods for the detection of AFP in the low concentration range. (2) In 3.72% of the cases a clinically unknown carcinoma was found in an unselected group of patients with liver cirrhosis. (3) 21.9% of the patients showed AFP elevations up to 2000 ng/ml. In 10.6% of this group, increasing titers demonstrated a primary liver cell carcinoma. In 89.4% a transitory rise of AFP was not associated with tumor growth. Levels return to normal values within three months in 90% of the cases. (4) Transitory AFP elevations are not correlated to clinical conditions (praecoma, coma, delirium, bleeding, ascites, shunt) or to biochemical parameters (GOT, GPT, bilirubin, prothrombin complex time, gamma-globulin). (5) A temporary rise in AFP is more frequently observed in groups with high hepatoma incidence than in groups with low hepatoma incidence. (6) Therefore, it may be suggested that a transitory rise of AFP could reflect a "primary reaction" of carcinogenesis. (7) Primary liver cell carcinoma is found to be more frequent in posthepatitic than in postalcoholic, cryptogenic, and other cirrhosis and to be more frequent in australia-antigen positive than in australia-antigen negative cases. (8) Routine serological tumor antigen screening of patients with a precancerous disease is useful.

The turnover of purified radiolabelled plasminogen was studied in four patients with cirrhosis of the liver, and that of radiolabelled prothrombin in six patients with cirrhosis of the liver. The cirrhotic patients showed an increased fractional catabolic rate and a decreased synthetic rate, resulting in subnormal plasma levels of plasminogen and prothrombin. The plasma concentration of the two proteins correlated with the synthetic rate, but not with the fractional catabolic rate. Heparin infusion prolonged the shortened half-life of plasminogen in two cirrhotics from 1.25 to 2.10 days and from 1.45 to 1.90 days, and the half-life of prothrombin in three cirrhotics from 2.25 to 2.70 days, from 2.35 to 2.80 days and from 2.40 to 3.70 days. These results indicate that the abnormal turnover of labelled plasminogen and prothrombin in cirrhosis of the liver is due to two mechanisms; increased breakdown, reversible by heparin administration, and impaired synthesis. The decreased plasma levels are, however, mainly caused by decreased synthesis.

Fifty cystic fibrosis (CF) patients, of whom 9 had multilobular cirrhosis, were observed regularly for a period of 3 years and various liver function tests, indicating cytolysis, cholestasis and cellular insufficiency were performed. Immunoglobulin and prothrombin were assayed. In 9 patients with cirrhosis, the tests were generally abnormal. Two distinct biochemical patterns of cirrhosis were distinguished, one clearly cholestatic and the other of a more cellular type. The distinction was made on the basis of the IgA : Transferrin ratio and of gamma-glutamyl-transpeptidase levels. In the non-cirrhotic patients, a temporary increase of cytolysis and cholestasis was observed in 50% of the cases.

The pharmacokinetics of paracetamol were studied in 11 patients with cirrhosis of the liver and 12 controls. The average biological half-life after oral administration of 1 g paracetamol was significantly prolonged in patients with hepatic cirrhosis compared to the controls (3.7 hr vs.2.1 hr) and, correspondingly, the average plasma clearance was significantly reduced from 337 ml x min-1 in the controls to 162 ml x min-1 in the patients with cirrhosis of the liver. After subchronic dosing of paracetamol with 1 g paracetamol t. i. d. the plasma half-lives of paracetamol remained unchanged. Steady-state levels of paracetamol were significantly increased in the patients with cirrhosis of the liver. A significant correlation between the values of plasma clearance of paracetamol and prothrombin time (r = +0.88), galactose elimination capacity (r = +0.66), plasma albumin (r = +0.85) was found. No clinical or biochemical signs of hepatotoxicity were observed during the study.

In 75 cases of histologically verified liver cirrhosis the plasma amino acids were determined by ion exchange chromatography and the results were correlated with different liver function tests as prothrombin time, pseudocholinesterase, serum albumin, GOT, bilirubin and venous ammonia. Out of these parameters prothrombin time, pseudocholinesterase and serum albumin significantly correlated with the sum of branched-chain amino acids and with the Fischer's quotient (molar ratio of branched-chain and aromatic amino acids). Methionin and aromatic amino acids inversely correlated with these parameters, additionally methionin positively correlated with bilirubin and GOT. By comparing plasma amino acid levels in cirrhotics without and with hepatic encephalopathy (grade 3 or 4) no significant differences were found. "Fischer's quotient" showed an overlap in patients with and without encephalopathy. Therefore the precipitation of hepatic encephalopathy is not fully explained by the changes in plasma amino acids. Therapeutic administrations of specially mixtures of amino acids with a high content in branched-chain and a low content in aromatic amino acids correct the plasma amino inbalance for a short time and improves hepatic encephalopathy.

Thirty patients with cirrhosis were evaluated with the 2-hr [14C]aminopyrine breath test (score) and with conventional liver tests. Of the 30 patients, 24 also had current liver biopsies. There was a good correlation between necroinflammatory activity in the 24 cirrhotic liver biopsies and the 2-hr aminopyrine scores. All five patients who had at least grade 2 necroinflammatory activity on their biopsy had an abnormal prothrombin time (greater than 3.5 sec above control) and their aminopyrine score was less than 2%. The correlation was good between the 2-hr aminopyrine score and the prothrombin time (seconds over control). No correlation was found between the 2-hr aminopyrine score and either the serum aspartate aminotransferase (SGOT) or any other liver test except for the prothrombin time. It seems that the 2-hr aminopyrine score and prothrombin time are more likely to give a quantitative estimate of total functioning parenchymal mass which is left unaffected by hepatocellular disease in cirrhosis, than the other commonly used liver tests.

Levels of serum triiodothyronine (T3), reverse triiodothyronine (rT3), and thyroxine (T4) were determined in 29 patients with alcoholic cirrhosis, seven patients with acute hepatitis, and 14 control patients hospitalized for chronic disease. Serum T3 levels were decreased significantly and serum rT3 levels increased significantly in the patients with alcoholic cirrhosis. Serum T3 and T4 levels were lower and rT3 levels higher in the cirrhotic patients who died within three months of the study compared with those who survived. A combination of prothrombin time, aminopyrine breath test results, and rT3 and T3 determinations gave significant predictive information about survival in patients with cirrhosis. The data suggest that assay of serum thyroid hormone levels together with prothrombin time and the aminopyrine breath test may be helpful in assessing the course and prognosis of patients with liver disease.

Six patients suffering from chronic liver disease attributed to oxyphenisatin ingestion are presented. They seem to be the first such cases reported in France. These patients were between 22 and 69 years old, 5 of them were female. Three patients had a chronic active hepatitis (CAH). In these three subjects the onset of the illness was a jaundice ; alanine transaminase (ALAT) exceeded 5 times the upper limit of the normal value ; smooth muscle antibodies were present in 2 patients and antinuclear antibodies in the third. Two other patients had cirrhosis, without chronic active hepatitis ; none presented autoantibodies. The sixth patient suffered from a subacute hepatitis, suggested by the presence of jaundice and ascites, high levels of serum ALAT and a very prolonged prothrombin time ; smooth muscle antibodies were present. In all cases, HBs Ag was absent from serum. Each patient had ingested laxative pills containing oxyphenisatin for 4 to 25 years ; the total amount ingested was comprised between 12.5 and 350 g. The chronic liver diseases reported in this series closely resemble those published in the literature. The lesions observed make it necessary to look for oxyphenisatin ingestion in every patient having CAH or cirrhosis without known etiology. These chronic liver diseases imply the rapid withdrawal of oxyphenisatin from french market, as already enforced in Australia and the United States.

The present study reported a group of 168 chronically alcoholic patients with a daily ingestion superior to 80 grams. Twenty of these patients (10 percent) did not have liver disease, and 148 (68.5 percent) had different forms of liver disease classified by histopathologic examination. Considering a 97 fi MCV as macrocytosis, we have found in the group of alcoholics without hepatopathy a 50 percent rate of macrocythemia with a mean value of 97.9 fl. In the group of chronic alcoholics with liver disease there was a 64.2 percent macrocytosis with a mean value of 100 fl. We have also studied 43 (21.5 percent) patients with cryptogenetic cirrhosis with a 32.6 percent macrocytosis and a mean value of 93.9 fl. With respect to the alcoholic hepatopathy subgroups, macrocytosis is more frequent in portal fibrosis and acute alcoholic hepatitis, the mean value being higher in the latter. We consider macrocytosis to be frequent among alcoholics, and a good persistence indicator of alcoholic ingestion, pathogenically linked to the now proven dyserythropoietic factor of the alcohol upon the bone marrow. There is no statistically significant correlation between anemia and reticulocytes. We consider macrocytosis to be a more precocious data, and believe that the positive correlation with certain intraerythrocitary enzymes in the juvenile population of red cells corroborates this fact. With respect to the rest of parameters studied there was a correlation with gammaglutamiltranspeptidase, glutamic-oxalacetic transaminase, and the value of prothrombin. The values of mean macrocytosis and elevations of gammaglutamiltranspeptidase and glutamic-oxalacetic transaminase are good persistence indicators of alcoholic ingestion.

The frequent occurrence of abnormal fibrin polymerisation in patients with liver disease has recently been reported. To investigate this further, fibrin polymerisation was studied in 68 patients with cirrhosis or chronic active liver disease. Thirty-three of these patients demonstrated impairment of this phase of blood coagulation. When other tests of liver function were compared in patients demonstrating this abnormality and those in whom fibrin polymerisation was normal, it was found that the former group demonstrated significantly reduced albumin concentrations (p less than 0.0002), raised bilirubin and aspartate aminotransferase levels (p less than 0.0006 and less than 0.003 respectively), and greater prolongation of the one-stage prothrombin time (p less than 0.001) with more marked reduction in factor VII levels (p less than 0.002) compared with the latter patients. It is concluded that defective fibrin polymerisation occurring in patients with liver disease indicates the presence of severely impaired hepatocellular function. This might account for the grave prognosis reported in cirrhotic patients with abnormal fibrin polymerisation who also suffer bleeding from gastro-oesophageal varices.
