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.)

We have studied the pharmokinetics of cis-trans, trans-trans and cis-cis mivacurium in 10 healthy subjects and 11 patients with mild or moderate hepatic cirrhosis, during nitrous oxide-oxygen-isoflurane anaesthesia. Mivacurium 15 micrograms kg-1 min-1 was infused for 10 min (total dose 0.15 mg kg-1) and the plasma concentration of the three isomers measured at regular intervals for 190 min. The electromyographic response to the drug was also measured. Compartmental analysis of the resulting isomer profiles was undertaken: one- and two-compartment models were fitted to derive clearance, volume of distribution and half-life. Clearance of the cis-trans and trans-trans isomers was reduced significantly in the cirrhotic compared with the healthy group: cis-trans (median (range)) 44 (15-121) ml kg-1 min-1 vs 95 (57-213) ml kg-1 min-1 (P < 0.05); trans-trans 32 (12-64) ml kg-1 min-1 vs 70 (34-101) ml kg-1 min-1 (P < 0.05). The difference in the clearance of the cis-cis isomer in the cirrhotic (4.2 (2.9-12.1) ml kg-1 min-1) compared with the healthy group (5.2 (2.9-8.9) ml kg-1 min-1) was not significant with this sample size. Clearance of each isomer correlated significantly with plasma cholinesterase activity: cis-trans r = 0.73, P < 0.001; trans-trans r = 0.69, P < 0.001; cis-cis r = 0.48, P < 0.05.(ABSTRACT TRUNCATED AT 250 WORDS)

The noninvasive determination of effective hepatic blood flow, intrahepatic shunted blood flow, intrahepatic shunt index, and total hepatic blood flow was investigated by using the sequential single photon emission computed tomography. This method was performed for a period of 10 minutes following an intravenous injection of 99mTc-(Sn)-N-pyridoxyl-5-methyltryptophan and a venous blood sampling. This study comprised 8 healthy volunteers, 16 patients with chronic hepatitis, and 33 patients with liver cirrhosis. The intrahepatic shunt index measured with this method coincided with the intrahepatic shunt index determined by catheterization, indicating the high reliability of this procedure. The effective hepatic blood flow in patients with liver cirrhosis was significantly lower than that in the healthy controls and the chronic hepatitis group. The intrahepatic shunted blood flow was significantly higher in patients with liver cirrhosis compared with the flow in healthy controls. The intrahepatic shunt index was also significantly higher in patients with liver cirrhosis compared with the index of healthy controls and those with chronic hepatitis. No substantial differences were noted in the total hepatic blood flow among the three groups. The effective hepatic blood flow, the intrahepatic shunted blood flow, and the intrahepatic shunt index, correlated with the serum albumin concentration, the serum cholinesterase level, and the plasma indocyanine green attenuation rate. From these results, it was concluded that the present procedure constitutes a reliable and effective method for the noninvasive determination of hepatic blood flows. Consequently, it will be of high clinical value for assessing the functional and the pathological alterations of the liver.

We measured urokinase-type plasminogen activator (u-PA) plasma levels in patients with various chronic liver diseases, including hepatocellular carcinoma (HCC), also measuring these levels in healthy volunteers. Plasma u-PA levels in the group of patients with decompensated liver cirrhosis (mean modified Pugh score of 14 points) were markedly elevated and significantly higher than those in the patients with decompensated liver cirrhosis with HCC (modified Pugh score of 10 points), those with compensated liver cirrhosis with HCC, and those with compensated liver cirrhosis. Patients in all these three latter groups had moderately and significantly elevated u-PA levels compared to levels in the chronic hepatitis group and the healthy volunteers, but the levels were not significantly different from each other. There was no relationship between u-PA plasma level and the type of HCC tumor invasion or number or size of tumors. Significant correlations were found between u-PA plasma levels and the results of seven different liver function tests in three groups without associated HCC; u-PA antigen and prothrombin time (%), hepaplastin test (%), serum cholinesterase, serum albumin, serum total cholesterol, and indocyanine green clearance correlated negatively, while u-PA antigen and serum total bilirubin correlated positively. These results suggest that plasma u-PA is associated with deterioration of liver function but not with HCC invasion.

The authors measured immunoenzymatically circulating intercellular adhesion molecule-1 (cICAM-1) concentration in 135 patients with liver disease of either viral or toxic etiology: 13 had acute hepatitis; 58 had mild chronic liver disease; and 64 had cirrhosis (superimposed in 30 by hepatocellular carcinoma). Forty patients with extrahepatic diseases (19 with malignancies) and 28 healthy blood donors were tested as controls. One-way analysis of variance demonstrated a significant variability of cICAM-1 concentration among groups (F = 76.67, P < .0001), the highest value being recorded in acute hepatitis (Bonferroni's test for pairwise comparisons, P < .01). Total bilirubin showed a strong correlation with cICAM-1 (R = 0.766, P < .001). By stepwise multiple regression analysis the independent predictors of cICAM-1 concentration were chosen in the following order: total bilirubin; aspartate aminotransferase; cholinesterase; alpha-1-antitrypsin; and immunoglobulins. Thus, in addition to inflammation, cholestasis and decline of functioning hepatic mass may influence cICAM-1 concentration.

Cocaine was the first drug to be used as a local anaesthetic. It was introduced into medicine in 1884 by Koller. Other drugs soon followed, for example, ethyl chloride spray, tropocaine, eugenol (oil of cloves) and Nupercaine. A wide range of uses for local anaesthetics soon developed and the term 'regional anaesthesia' was first used by Cushing in 1901 to describe pain relief by nerve blockade. Local anaesthetic drugs are water soluble salts of lipid soluble alkaloids. Each molecule is composed of an aromatic portion, intermediate chain and an amide portion. The portions are joined by either amide or ester linkages. Ester-linked drugs are hydrolysed in the plasma by plasma cholinesterase and their half-life varies from one to eight minutes. Amide-linked drugs are degraded by oxidative dealkylation in the liver. The half-life of these drugs varies from 1.5 to more than three hours. The addition of a vasoconstrictor, such as adrenaline, will prolong the duration of action of both the amide- and ester-linked drugs. Degradation of the amide-linked drugs depends on factors such as hepatic blood flow and liver conditions, such as cirrhosis, and congestive cardiac failure. Anaphylactic reactions are more common with ester-linked drugs than amide-linked drugs. The drugs are usually available for injection as hydrochlorides in a salt solution with small amounts of fungicides or preservatives added to give stability.

Protein S is a vitamin K-dependent glycoprotein acting as a cofactor for activated protein C and thereby exerting an antithrombotic effect. When compared to values recorded in the 10 healthy normal weight normolipidemic control subjects (80.1% +/- 5.16; mean +/- SEM), plasma protein S-antigen (PS:Ag) level was found to be significantly (p < 0.01) decreased in the 11 patients with decompensated cirrhosis of the liver (54.72% +/- 4.89) and in the 12 surgical patients in critical condition (59.2 +/- 4.96), while obviously (p < 0.001) increased plasma levels were noted in the group including 20 overweight and hyperlipidemic subjects (113% +/- 3.1). Since the low PS:Ag level was associated with a decreased serum cholinesterase (CHE) activity, while both plasma PS:Ag and serum CHE activity were increased in overweight and hyperlipidemic subjects it is considered that impaired or respectively enhanced hepatic protein synthesis is at least partially responsible for changes affecting this antithrombotic plasma protein.

We examined the serum levels of testosterone (T), androstenedione (delta 4-A), estrone (E1), estradiol (E2), and dehydroepiandrosterone sulfate (DHEA-S) in the non-alcoholic cirrhotic male patients when divided into compensated or decompensated state. Serum level of T was significantly elevated in compensated cirrhotic patients (9.63 +/- 1.00 ng/ml, mean +/- SE) compared to that in decompensated cirrhotic patients (5.63 +/- 0.69 ng/ml, p < 0.01) and in aged-matched normal controls (4.95 +/- 0.38 ng/ml, p < 0.01). Serum levels of E1, E2 and delta 4-A tended to be increased in decompensated cirrhotic patients, while there was not a significant difference decompensated cirrhosis compared to those of normal controls. Serum concentration of cholinesterase, indicative one of the representative residual liver function, showed a good positive correlation to T (r = 0.53, p < 0.01), and a negative correlations to E1 (r = -0.67, p < 0.01), E2 (r = -0.77, p < 0.01), delta 4-A (r = -0.57, r = p < 0.01). Also, we examined the relationship of the serum levels to gynecomastia or esophageal varices. The cirrhotics with gynecomastia showed significantly higher serum levels of E1, E2, and delta 4-A, and lower level of T than those without gynecomastia. And the cirrhotics with esophageal varices showed the greater level of T than those without esophageal varices. Our study suggests that low serum testosterone level of men with nonalcoholic cirrhotic is not a common finding, especially in compensated state.(ABSTRACT TRUNCATED AT 250 WORDS)
