Isoenzyme V of 5'-nucleotide phosphodiesterase (5'-NPD-V) is present in the peripheral sera of patients with hepatic metastases. A total of 122 patients underwent prospective serologic analysis followed by operation for primary tumors of the gastrointestinal tract and careful evaluation of the liver. A positive 5'-NPD-V assay was found in fifty-nine of sixty patients with liver metastases. A negative 5'-NPD-V assay was found in forty-three of sixty-two patients with no evidence of hepatic metastases. The accuracy of the test was 84 per cent, and the predictive value was 75 per cent. Serum 5'-NPD-V was abnormal significantly more frequently in patients with metastatic liver disease than were liver scans or carcinoembryonic antigen (CEA), alpha fetoprotein, serum glutamic oxalacetic transaminase (SGOT), and total serum bilirubin or serum alkaline phosphatase levels.

A prospective study of the natural history of acute hepatitis B was performed in 38 patients. Fatigue started median 4 weeks, abdominal symptoms median 3 weeks and signs of cholestasis median 2.5 weeks before peak SGPT values were reached. Extrahepatic manifestations occurred throughout the prodromal stage, the presence of arthropathy, urticaria or skin rashes was not related to the biochemical severity of liver disease. The higher the the maximal values of serum bilirubin and/or the older the patient, the longer the period of bilirubin elevation; a maximal bilirubin elevation less than 20 X the upper limit of normal was associated with normalisation of serum bilirubin within 6 weeks. No such correlations were found between the height of serum glutamic pyruvic transaminase, alkaline phosphatase, thymol turbidity and cholesterol levels and the subsequent duration of their abnormality. The elevation of alkaline phosphatase as well as the abdominal complaints might partly be caused by gastro-intestinal involvement. Immobilisation before peak SGPT was attained was associated with normalisation of serum glutamic pyruvic transaminase levels within 8 weeks after peak levels. 37 patients recovered completely. In one HBs-antigenemia and slight SGPT elevation persisted. Long term follow up was possible in 33 patients for 4 to 7 years, median 5 years.

Serum bile acids were measured in 28 patients with established liver disease. The peak serum level after a meal was as sensitive an index of liver disease as a combination of serum bilirubin, aspartate amino transferase, alkaline phosphatase and gamma glutamyl transpeptidase and was more often abnormal than any one of the four tests. Serum bile acid measurements may be of most value in detecting cirrhosis when the activity of disease is minimal.

We used the previously described [Clin. Chem. 19, 1114 (1973)] and evaluated [Clin. Chem. 19, 1122 (1973)] computer-controlled instrument system for sequential chemical testing to select and perform tests of hepatic status, to aid the clinician in the diagnosis of liver disease. Results for total bilirubin, aspartate aminotransferase, and alkaline phosphatase obtained from the continuous-flow analysis (SMA 12/60) admission screen were used by the instrument system to determine selectively the values for gamma-glutamyltransferase, alanine aminotransferase, creatine kinase, and total and direct bilirubin. Kit methods for the latter four tests were evaluated on the system; results were similar to manual procedures. A software, enzymatic ratemeter was found to be better than the previously described hardware ratemeter. The follow-up tests of serum prescribed by the system are compared to clinician-prescribed follow-up tests and discharge diagnoses. In 10 of 19 cases, the system and clinician ordered similar follow-up tests; in three cases follow-up differed, and in six cases, the system ordered follow-up tests and the clinician ordered none.

As part of a double-blind, randomized, controlled trial to evaluate the effect of colchicine on liver cirrhosis, 43 cirrhotic patients were assigned to either a placebo (20 patients) or a colchicine (23 patients) treatment group. Colchicine 1 mg and an indistinguishable placebo were administered orally on a daily dose 5 days a week. In the colchicine group, 12 were males and 11 females, while in the control group 13 were males and 7 females. The time elapsed between diagnosis and inclusion in the study was 14.1 mo for the controls and 14.5 mo for the patients on colchicine. Mortality related to the liver disease occurred in 4 patients on colchicine and 8 patients on placebo. Although the probability of surviving in the colchicine group was greater than that of the placebo, the difference did not reach statistically significant levels. Of the colchicine-treated patients, in three a remarkable decrease in liver fibrosis was observed in serial biopsies. In two other patients, carcinoma of the liver developed. Six of the survivors on colchicine have improved clinically, noticing disappearance of ascites and edema, as well as a decrease in the size of the spleen. All the survivors on placebo continue to show clinical deterioration. In contrast to the usual drop of serum albumin seen in the cirrhotic patients, those receiving colchicine increased and maintained their serum albumin levels throughout the study. Serum proline values were elevated only in the alcohol cirrhotic patients. Serum alkaline phosphatase increased only in those patients receiving colchicine. The results indicate that in some cases, liver fibrosis could be modified by treatment with antifibrotic drugs. The use of colchicine at present should remain within controlled studies.

High molecular weight alkaline phosphatase activities have been measured in the sera of 72 patients with a variety of forms of liver disease, 14 patients with bone disease and 8 healthy volunteers. These measurements have been compared with measurements of other indices of hepatic function in order to establish the place of this enzyme in the diagnosis of liver disease. High molecular weight alkaline phosphatase proved to be a sensitive and specific tests for detecting liver disease, particularly obstructive liver disease. It was better than all the other liver function tests in distinguishing liver metastases from other hepatobiliary diseases. It may therefore prove especially useful in the early detection of liver metastases.

1. The activity of dopamine-beta-hydroxylase (DBH) was assayed in the serum of 102 patients, mostly with varying degrees of hepatic dysfunction. 2. DBH activity was not elevated in those with liver disorder and did not correlate with serum bilirubin, transaminase, lactic dehydrogenase, alkaline phosphatase or creatine phosphokinase. 3. It is concluded that the liver is not necessarily involved in the inactivation of DBH.

For the evaluation of certain differences in the diminution of export proteins of the liver we examined some exactly defined groups of liver diseases with the aim of further differentiation of the pathogenetic mechanisms. We measured the activity of glutamate-oxalacetate transaminase, glutamate-pyruvate transaminase, glutamate dehydrogenase, lactate dehydrogenase, alkaline phosphatase, cholinesterase and lecithin-cholesterol acyltransferase, the Quick value, the coagulation factors I, II, V, VII, VIII, IX and X. Clotting factors were determined by a Schnitger-Gross Coagulometer. Prothrombin, antithrombin III, plasminogen, factor VIII associated antigen and activated factor XIII were measured by immunoelectrophoresis according to Laurell. Lipoprotein electrophoresis in agarose gel was performed to evaluate changes in lecithin-cholesterol acyltransferase activity. Except of the rising diminution of export proteins in the course of liver disease from acute hepatitis to cirrhosis we found also specific changes of the patterns of the plasma specific enzymes. These proteins were diminished dependent on their half life time and the inflammatory activity--measured as the height of the transaminases. Lecithin cholesterol acyltransferase and factor VIII did not participate in the general diminution of the most export proteins; some details were found to explain this differing behaviour. Results are critically discussed with regard to new aspects in the biochemistry of the damaged liver cell.

The mean plasma carcinoembryonic antigen (CEA) level was found to be significantly increased in 66 patients with alcoholic liver disease (4.4 micrograms/1) compared with the mean CEA level in 164 healthy blood donors (1.6 micrograms/1, p less than 0.001). Eighteen of the patients (27%) had values above our upper normal values of 5 micrograms/1, compared with 3 of 41 (7%) in a group of patients with non-alcoholic liver diseases. On the other hand, the mean CEA values in the two groups did not differ significantly. The CEA level remained unchanged in patients who continued drinking. However, in 20 patients who stopped drinking, the mean CEA levels dropped significantly from 6.6 micrograms/1 to 3.7 micrograms/1. Concomitant fluctuations were seen in CEA, gamma-glutamyltranspeptidase (gamma-GT), asparate aminotransferase (ASAT), and alkaline phosphatase, although a significant correlation was found only between CEA level and the level of gamma-GT (r = 0.32, p less than 0.02). The correlation between CEA and gamma-GT was best in 41 patients without complicating disorders (r = 0.55, p less than 0.001). CEA was significantly increased in patients with complicating disorders. Much of the increase of CEA in many patients with alcoholic liver disease might be secondary to complicating disorders in the respiratory and/or gastrointestinal tracts. This could possible explain why patients with alcoholic liver disease more often than other patients with benign diseases have elevated CEA.

Admission serum triiodothyronine (T3) values in 124 patients hospitalized for alcoholic liver disease were correlated with clinical and laboratory indices of liver function and commonly used determinants of thyroid function. Patients with low admission serum T3 levels had significant alterations in serum albumin, bilirubin, prothrombin time, and alkaline phosphatase associated with clinical signs of portal hypertension and collateral circulation, with little difference in serum glutamic-oxaloacetic transaminase, serum gamma glutamyl transpeptidase, or serum ornithine carbamyl transferase. This group also had a significant decrease in free T3 index despite an increase in T3 uptake; the slight reduction in total thyroxine (T4) was associated with an increase in free T4 index and no change in serum thyrotropin (TSH). For patients with alcoholic liver disease, low admission serum T3 and free T3 index values when accompanied by normal serum T4, free T4 index, and TSH levels appear to be indicative of severe liver dysfunction and increased mortality risk.
