Lower concentrations of total serum zinc (540 +/- 111 mug/1, mean +/- SEM), and of albumin-bound serum zinc (295 +/- 113 mug/1) and a higher concentration of alpha2-macroglobulin-bound zinc (245 +/- 69 mug/1) were found in 25 patients with decompensated hepatic cirrhosis, compared to 28 healthy subjects (835 +/- 91; 679 +/- 83; 156 +/- 27 mug/1 respectively). Levels of total and albumin-bound zinc were significantly and positively correlated with serum albumin levels. Higher levels of alpha2-macroglobulin-bound zinc were associated with higher levels of alpha2-macroglobulin in these patients (2.8 +/- 0.8 g/1) compared to normals (2.3 +/- 0.6). Hence, not only do decompensated cirrhotics exhibit a lower serum zinc level but a greater proportion of this zinc is associated with the tightly bound, and presumably metabolically more inert, serum fraction. This situation exaggerates the zinc deficiency state of the severe cirrhotic.

Radionuclide imaging with labeled colloids is widely used to evaluate and localize primary and metastatic tumors of the liver. The method is fairly sensitive, but the nonspecificity of focal defects remains a significant limitation. Lesions such as cysts and abscesses appear as space occupying areas that are indistinguishable from neoplastic masses. Utilizing a variety of radiopharmaceuticals, one may obtain additional information concerning such lesions. Hepatic blood flow scintiphotography is performed with the Anger camera following the intravenous injection of a high activity, small volume bolus of 99m-Tc pertechnetate. Vascular lesions such as hepatomas or hemangiomas will show increased activity in the lesion which should easily differentiate them from avascular processes such as abscesses, cirrhotic pseudomasses and most metastatic lesions, all of which remain "cold" on these flow studies. If one does not posses a camera, useful blood pool rectilinear scans of these lesions may be obtained with 131-I or 99m-Tc human serum albumin or ionic 113m-In. Additional information concerning the metabolic activity of focal defects on the colloid study is obtained using 75-Se-selenomethionine or 67-Ga. The former is an indicator of active protein metabolism while the latter attaches to lysozymes of metabolically active cells. With either agent, hepatomas show avid uptake, metastatic lesions show variable uptake, and cysts or chronic pseudotumors of cirrhosis show poor uptake. The two agents differ in abscess detection where 75-Se-selenomethionine uptake is poor while 67-Ga concentration generally is intense. 131-I-Rose Bengal occasionally may prove useful in demonstrating impression by an atypically positioned gallbladder or focal dilatation of the biliary tract as a cause of a defect on the colloid scan. Ultrasound examination may complement the radionuclide studies. It is useful for corroborating the presence of lesions and for evaluating their consistency (cystic vs. solid). The information obtained from this multinuclide approach has made scintigraphy examination of the livermore specific. After the completion of this non-invasive series of studies, one generally may venture an intelligent opinion concerning the etiology of the space occupying disease.

Serum albumin and total globulin were determined in 22 healthy people, 29 patients with acute viral hepatitis, 27 patients with cirrhosis and 27 patients with primary hepatocellular carcinoma to see if they might be of discriminating value. The mean serum albumin values were found to be highest in the healthy subjects followed by acute viral hepatitis, primary hepatocellular carcinoma and cirrhosis, in that order. The mean serum total globulin values on the other hand, were found to be lowest in the healthy subjects followed by acute viral hepatitis, primary hepatocellular carcinoma and cirrhosis, in that order. Both the mean albumin and mean total globulin of each group of subjects were significantly different from the respective means of the other three groups. A probable explanation for the higher serum albumin and lower globulin levels found in primary hepatocellular carcinoma, as compared to cirrhosis, is that hepatocellular carcinoma occurs in reasonably well-compensated cases of cirrhosis.

The plasma lecithin: cholesterol acyltransferase was determined in patients with various liver diseases and the relationship between this enzyme activity and the other liver function tests were studied including long term observations. Lecithin: cholesterol acyltransferase activity in fulminant hepatitis and liver cirrhosis showed a significant decrease in comparison with normal volunteers. Although the enzyme activity of hepatoma showed significant decrease, they were ascribed to the influence of concomitant liver cirrhosis. The enzyme activity showed insignificant changes in the acute and chronic hepatitis and alcoholic liver disease. Lecithin: cholesterol acyltransferase activity was correlated with the concentration of cholesterolester rather than with the ratio of esters to cholesterol. In addition, it was well correlated with pseudocholine esterase and serum albumin. The lecithin: cholesterol acyltransferase activity in the cases during follow-up period varied in good parallel with cholesterol-esters concentration and pseudocholine esterase in the cases with acute hepatitis; with serum albumin in the cases with liver cirrhosis. Furthermore, it varied inversely with SGPT in the cases with acute hepatitis. In a case with hepatoma, lecithin: cholesterol acyltransferase activity decreased more sharply than the cholesterolesters concentration and serum albumin immediately before death.

The concentrations of tryptophan in serum and CSF, as well as that of 5-HIAA in CSF were investigated in various group of patients. Those with hepatic cirrhosis have normal total serum tryptophan. However, because of the low concentration of serum albumin the percentage of nonalbumin-bound tryptophan is elevated about 50 percent above the mean control value. By contrast tryptophan in the CSF was increased by 50 to over 800 percent. This suggests that there is also an increase in brain tryptophan and serotonin in the cirrhotic patients. No significant difference was found for the concentrations of tryptophan in CSF of patients in coma and those not in coma. Patients with hepatic coma had an elevated concentration of 5-HIAA in the lumbar CSF which may reflect the increase in this compound and in serotonin reported by Jellinger and Riederer (1977). However, following treatment with probenecid in order to block the egress of 5-HIAA from the CSF, the concentration of 5-HIAA in relation to that of probenecid was not significantly different for the group with hepatic coma as compared with the control group.

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.

The results of the controlled study covering 21 cases of decompensated hepatic cirrhosis are repoted. Nine controls received conventional therapy with diuretics and vitamin supplement. Testosteron 100 mg intramuscularly, on alternate days for four weeks, was administered to 12 others, in addition to the conventional therapy. Patients in the testosterone group responded with reduction in ascites and pedal edema together with a subjective feeling of improvement. Serum albumin rose at the end of the four weeks while globulin fell in those that received the hormone. The difference in respect of both serum albumin and globulin in the testosterone group became statistically significant at the end of four weeks.

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.

Several hemodynamic abnormalities in the patient with cirrhosis comprise a unique distributive circulatory disturbance that causes intractable ascites and that is, in turn, worsened by the resulting ascites. Ascites is promptly alleviated by drainage of the ascitic fluid into the intravascular compartment. The circulatory abnormalities improve in part because of elimination of the ascites, and also because of a compensatory hypervolemia. The consequences of the latter, especially in the immediate postoperative period, are increased likelihood of pulmonary edema and of gastrointestinal bleeding from heightened portal vein pressure. Postoperative coagulopathy is also a significant problem. Careful selection of patients for the procedure, close postoperative observation and vigorous use of diuretics and other agents will usually enable these complications to be obviated or successfully treated. Increases in body muscle and fat masses and serum albumin concentrations indicate nutritional improvement. Despite evidence of benefits from the procedure, these patients continue to die from the complications that threaten other cirrhotics: effects of return to alcoholism, gastrointestinal hemorrhage, recurrent infections and intestinal obstruction. Thus, it is not yet clear that the benefits include prolongation of life.

The influence of renal failure and of hepatic cirrhosis on the plasma protein binding of etomidate, an intravenous anaesthetic agent of basic nature, has been investigated. The percentage of free etomidate in plasma containing 1 microgram/ml was markedly increased in patients with renal failure and in patients with hepatic cirrhosis, when compared with a group of healthy volunteers (43.4 +/- 2.9% and 44.2 +/- 2.1 versus 24.9 +/- 1.4%). This decrease in binding correlated inversely with serum albumin levels in both conditions (r = -0.88 and r = 0.72, respectively) but a slight decrease in the amount bound per mole of albumin was also apparent in both types of disease.
