The value of serum bile acid concentrations for predicting prognosis in cirrhotics was compared with the prognostic significance of clinical and laboratory findings in a prospective 1-year study of 76 patients with cirrhosis. A commercial radioimmunoassay for total serum-conjugated primary bile acids was used. Of 76 patients, 16 died within the follow-up period. The concentration of bile acids in serum more closely correlated with mortality in cirrhosis than the commonly used clinical and laboratory parameters such as the Number Connection Test, ascites, albumin, pseudocholinesterase, bilirubin, prothrombin time and nutritional state. Serum bile acids alone yielded a prediction of mortality comparable to the Child classification. When logistic regression analysis was performed, optimal prediction of prognosis was achieved with the combination of serum bile acids and the Number Connection Test. Serum bile acid levels alone or in combination with the Number Connection Test may be a clinically useful prognostic index in cirrhosis.

Sixty male workers in a lindane (gamma-hexachlorocyclohexane)-producing factory were examined with regard to health in comparison with an external control group of 20 clerks. Case history, physical examination, neurologic status, and ECG revealed no significant differences between groups. However, the following significant differences in clinical-chemical blood tests were ascertained: higher polymorphonuclear leukocyte count, lower lymphocyte count, higher reticulocyte count, lower prothrombin (Quick's) test, and lower blood concentrations of creatinine and uric acid. No significant differences were observed in total red and white blood cell as well as platelet counts, hemoglobin content, the other counts of differential blood picture, gamma-GT, GOT, GPT, LDH, cholinesterase, triglycerides, cholesterol, and urea. In spite of a pronounced exposure to the alpha-, beta-, and gamma-isomers of hexachlorocyclohexane, no signs of severe impairment of health were observed; only small deviations in some laboratory tests were found having no pathologic significance. However, biological monitoring and health supervision of HCH-exposed workers should be carried out.

A study was made of the fluorine-ion content in the vegetables and grain grown on experimental plots of land fertilized for 4-6 years with fluorine-containing fertilizers: active slurry potassium tetrafluoroborate and sodium fluorosilicate. It was found that the fluorine-ion content in individual samples of the vegetables and grain was increased 2-32-fold as compared to that in the control samples. As for the diet, the total content of fluorine-ion was increased 6.1-12.3-fold. Experiments were made on rabbits and rats whose diets contained the vegetables and grain from the experimental plots of land. The animals of the experimental groups manifested a lowering of the prothrombin index by the end of the 6th month of the experimental studies. There was a statistically significant fall in the cholinesterase activity and an increase in the activity of glutaminopyruvic aminotransferase (by 35-42 units). The activity of total alkaline phosphatase progressively increased at the expense of the elevated activity of liver and intestinal isozymes.

Patients with severe virus hepatitis and a prothrombin concentration below 25% have a bad prognosis. This is due to direct consequences of hepatic failure and to the rather frequent complications of this disease. The clinical course of such patients is essentially dependent upon the degree of liver regeneration, which again is dependent upon the mass of hepatocytes which are able to regenerate and upon the so called hepatotrophic factors. Patients with severe hepatitis suffer during the first weeks rather frequently from nausea and loss of appetite and for that reason their nutrition is insufficient. In the study recorded here 9 cases were investigated (7 patients with hepatitis B, 2 patients with hepatitis non A non B). The question was asked, if partial parenteral nutrition in addition to a liver diet not containing meat would improve liver function. It could be shown that the prothrombin concentration, which could not be improved by vitamine K1 supplements, was increased during a 7 day parenteral nutrition period from 19,3 +/- 2,9% to 41,5 +/- 8,1% (p less than 0,05), serum albumine and cholinesterase activity improved as well. During the first day of treatment there was a significant fall of ammoniac from 115 +/- 10 mumol to 73 +/- 10 mumol/l (p less than 0,05), at the same time production of urea did not increase. All patients survived. The results show, that parenteral nutrition can improve liver function and decrease the catabolic status of metabolism.

Because of its specific hepatic degradation tryptophan was orally administered (50 mg/kg) to patients with various chronic liver diseases (n = 30) and to healthy volunteers (n = 8) as a test for hepatic function. The plasma half life of tryptophan was determined between 4 and 8 h after the amino acid load. It was found that in patients with cirrhosis (n = 25) the half life of tryptophan was prolonged to 4.7 +/- 0.4 h (means +/- SD), compared to 2.0 +/- 0.1 h in the controls. The tryptophan half life also correlated with the plasma concentration of albumin, bilirubin, cholinesterase and prothrombin time in these patients. In addition a significant correlation was observed with the galactose elimination capacity and the 45 min retention of BSP. Thus, the oral tryptophan loading test may be suitable for a more specific determination of functional impairment of the liver in chronic liver disease. In decompensated cirrhotic patients alterations of the tryptophan metabolism seen to be related to indicators of hepatic encephalopathy. The test may therefore be used to assess the degree and risk of hepatic encephalopathy in such patients.

In vitamin K deficiency or treatment with vitamin K antagonists, a precoagulant of prothrombin (Factor II) called preprothrombin has been established. We measured preprothrombin with Clarke-Freeman electrophoresis in 26 patients with acute viral hepatitis (21 HBS-AG positive) who did not suffer from vitamin K deficiency. Prothrombin and the vitamin-K dependent Factors VII, IX, and X were determined by standard coagulometric methods. Prothrombin was additionally estimated by immunoelectrophoresis according to Laurell. Three patients with acute HBS-AG positive hepatitis showed preprothrombin in their plasma. The activity of Factors II, VII, IX, and X was slightly below normal with normal concentration of Factor II in the immunoelectrophoresis. Liver parenchymal damage and cholestasis were slight; the pseudocholinesterase showed subnormal levels in all three patients. Possible causes for the appearance of preprothrombin in the peripheral blood in acute viral hepatitis and the possible connections with liver cell damage are discussed.

The multicomponent solution, containing 15% of glycerol, 4.5% of proteins, 0.9% of sodium chloride, 0.33% of potassium chloride and water for injections, was proposed. The ferments activity (aminotransferases, cholinesterase, aldolase, alkaline phosphatase), blood coagulating system state (the prothrombin level, plasma tolerance, her recalcification time), the mineral elements contents (potassium, sodium, calcium), the contents of protein and its fractions in blood before and after an acute blood loss compensation with the multicomponent solution, and also its influence on the animals organism in prolonged daily (during 30 days) intravenous injection were studied. The combination of components in the solution permit to store the studying indexes on level close to initial; if the loss of blood compensates in the first hours, high survival of animals is insured. Negative reactions of organism while prolonged intravenous injection of the multicomponent solution are not revealed.

Fosinopril is distinguished from other ACE inhibitors by a pharmacokinetic pecularity in the sense that is can be metabolized either by liver or kidney. This was the rationale of the present research the aim of which was to verify if administered to patients with liver cirrhosis the drug was liable to alter global liver function and ability to metabolize drugs. Eight cirrhotic males, mean age 56 years, also suffering from high blood pressure, were studied. In these patients, liver and kidney function tests (BUN, creatinine blood level, serum and urinary electrolytes, creatinine clearance, calcium and phosphor blood level, transaminases, alkaline phosphatase prothrombin time, cholinesterase, gamma-glutamyl-transpeptidase) were carried out at baseline and after 30 days' fosinopril treatment (1 capsule every morning in the fasting state); in addition total functioning liver mass was assessed by the galactose test, and drug-metabolizing capacity by the antipyrine test. Treatment resulted in a significant improvement of pressure values in all patients (p < 0.01) and did not alter liver and kidney function parameters. Besides, no side effects were registered, especially no case of orthostatic hypotension. The antipyrine test was not influenced by fosinopril treatment. Therefore, short-term treatment with this ACE-inhibitor can be concluded to be effective and not to cause additional alterations of liver function in patients with liver cirrhosis.

This study investigated the relationship between urinary sodium excretion and liver function, as assessed by the aminopyrine breath test (ABT) and conventional parameters, in 62 patients with cirrhosis kept on a constant salt diet. Urinary sodium excretion was related non-linearly to the ABT (r = 0.76). Less significant correlations were observed to the Child-Pugh score (r = -0.65), cholinesterase (r = 0.58), bilirubin (r = -0.56), albumin (r = 0.51) and prothrombin time (r = 0.49). When patients were arbitrarily divided into 6 groups according to the ABT, sodium excretion balanced the sodium intake up to a 50% reduction in ABT. In groups with more than a 50% reduction sodium retention occurred. When patients were grouped according to the Child-Pugh score, urinary salt output was balanced in patients with scores of 5 and 6 and decreased in patients with scores greater six. However, the change in sodium output from normal salt excretion to sodium retention was less pronounced in patients grouped according to the Child-Pugh score than in patients grouped according to the ABT. The results suggest a non-linear relationship between the impairment in hepatic and renal function in cirrhosis. They are compatible with the concept of a threshold of hepatic function necessary to maintain normal renal function.

Assessment of the galactose elimination capacity has appeared to represent an suitable index of the total metabolic capacity of the liver inflicted with chronic hepatopathy. In a more severe disease e.g. cirrhosis hepatis the GEC assessment enabled to judge appropriately the among of hepatic tissue reduction which does not necessarily have to correspond with the grade according to Child-Pugh classification. It represents an helpful criterion also for a smaller decrease of the functional capacity of the liver, e.g. in moderate forms of hepatopathies, as e.g. steatosis and steatofibrosis hepatis, chronic active hepatitis. By means of examinations of the hepatic proteosynthetic function indices it was discovered that the level of prealbumin and the activity of cholinesterase are more sensitive parameters of the functional ability of impaired liver in comparison with albumin, prothrombin complex and transferrin. Assessment of prealbumin and cholinesterase in the group of patients with cirrhosis hepatis enabled the most significant mutual distinction of differently severe grades, in three differing subgroups of cirrhotic patients (Ci A, Ci B and Ci C). The presented parameters were significantly distinct also in groups of patients with chronic active hepatitis, and steatosis and steatofibrosis of the liver. (Fig. 6, Tab. 1, Ref. 29.)
