Anti-low-density lipoprotein antibodies in alcoholics without and with liver disease and in social drinkers.

Antibodies directed to native and to in-vitro acetaldehyde-modified (ethylated) low-density lipoproteins (LDL) were determined in 28 alcoholic subjects divided into two groups: one with no clinical nor laboratory evidence of liver involvement and the second with histologically proven alcohol-related liver disease. The control group consisted of 18 individuals who drank alcohol socially. In the individuals with alcoholic liver disease IgG reactivity against both native and ethylated LDL was significantly higher than in alcoholic individuals without liver injury. High levels of IgG reactivity in individuals with alcoholic liver disease were also observed against malondialdehyde-modified, methylated, acetylated and carbamylated LDL. A selective high anti-ethylated LDL IgG reactivity was observed in 11% of control subjects.

Comparative analysis of plasma lipoprotein components assessed by ultracentrifugation in primary biliary cirrhosis and chronic hepatitis.

UNLABELLED: The evaluation of lipid and lipoprotein profiles in liver diseases has important cognitive aspects and provides practical information contributing to the diagnosis of liver pathology. There are few studies of this problem using the ultracentrifugation method. AIM OF THE STUDY: A comparison of lipid profile (obtained by plasma ultracentrifugation) in patients with primary biliary cirrhosis (PBC) and chronic hepatitis (CH). MATERIAL AND METHODS: 103 percutaneous liver biopsies were routinely performed from 1994 to 1997. Blood samples were taken from all the patients at the time of biopsy for further evaluation of lipid profile. 15 patients with PBC and 15 patients with CH (of HBV or/and HCV etiology) were studied. RESULTS: In patients with CH mean total, esterified and free cholesterol levels (166 mg%, 117.6 mg% and 48.1 mg%, respectively) were significantly lower (p < 0.002; p < 0.004; p < 0.006, respectively) than in patients with PBC (237.5 mg%, 165.7 mg% and 71.8 mg%, respectively). The phospholipid concentration in sera of patients with PBC were significantly higher (271.1 mg%, p < 0.0004) than in patients with CH (187.6 mg%), whereas apolipoprotein B and apoAII were significantly lower. Total, esterified and free cholesterol levels in LDL fraction were significantly higher in patients with PBC (175.3 mg%, p < 0.007; 117.9 mg%, p < 0.02; 57.6 mg%, p < 0.01, respectively) than in patients with CH (113.7 mg%, 78.7 mg% and 35 mg%, respectively). The concentration of phospholipids in LDL fraction in patients with PBC was significantly higher (166.8 mg%; p < 0.003) in comparison with patients with CH (96.3 mg%). The differences in other lipoprotein fractions (VLDL and HDL) were not statistically significant. CONCLUSIONS: High levels of total, free and esterified cholesterol as well as phospholipids, apolipoprotein B and AII were observed by us in patients with PBC in comparison with patients suffering from CH. The increase of cholesterol (total, esterified and free) and the phospholipid concentration in serum, are a manifestation of their higher concentration in LDL fraction.

Significance of serum lipoproteid-X (LP-X) determination for the diagnosis of cholestasis in chronic liver diseases.

Among 179 patients with various chronic diseases of the liver the authors found in 20 cases histological evidence of intrahepatic cholestasis and in all these cases lipoproteid X (LP-X) was present in the serum. In the group of 159 patients without evidence of cholestasis in microscopic examination of liver tissue LP-X was demonstrated only in two cases (1.3%). The results of investigations confirm the view that detection of LP-X in the serum is a specific and sensitive index of cholestasis and its value in the diagnosis of this condition is greater than that of determinations of alkaline phosphatase, gamma-glutamyl-transpeptidase, leucinamino-peptidase activity or cholesterol in the serum.

Diagnostic importance of lipoprotein-X (LP-X) in the diagnosis of cholestasis.

In 317 patients with diseases of the liver and bile tract the authors determined LP-X in the serum and the obtained results were compared with the morphological findings in liver tissue or intraoperative examination of the extrahepatic bile ducts. Int he same patients serum bilirubin, total cholesterol, alkaline phosphatase activity, gamma-glutamyltranspeptidase and leucylaminopeptidase activity were determined. In the light of these results the authors believe that detection of LP-X in the serum is a sensitive and specific method in the diagnosis of cholestasis and that it is of greater usefulness than determination of alkaline phosphatase activity. Determinations of other biochemical parameters is of small diagnostic importance in these cases.

["Hepar"--the clinical computer system and its diagnostic and didactic use].

The possibilities of application of the "Hepar" computer system in medical didactics are discussed. The usefulness of hepatological diagnosis assistance with information++ systems is described and the multistage schema of diagnostic management is presented. In the conclusions the advantages of this system in medicine teaching is stressed and its usefulness in clinical practice is outlined.

[Primary biliary cirrhosis--analysis of clinical material].

The analysis is presented of 67 patients with primary biliary cirrhosis treated in the years 1971-1988. The group consisted of 60 women (89.5%) and seven men (10.5%). Presenting symptoms were mostly itching (66%) and jaundice (12%). The time between the onset of the first symptoms and the diagnosis was three years, on the average. Autoantibodies to mitochondria were present in 86% of patients. In 27% of cases markers of HB virus infection were found. Cholelithiasis was present in 19 patients (28%). Primary biliary cirrhosis was diagnosed with delay. Third degree of histological changes was observed in 38.8% of cases and in 18% of patients it was already fourth degree. Eighteen patients (27%) died after six years, on the average, from the onset of symptoms. The direct causes of death were, most frequently, liver failure and haemorrhage from oesophageal varices.

[Activity of beta-hexosaminidase in serum of patients with alcoholic and nonalcoholic liver diseases].

The total activity and thermostable activity of serum beta-hexosaminidase were determined in alcohol-dependent patients with liver damage, in non-drinking hepatic patients, in alcohol-dependent presently drinking patients who had no hepatic symptoms and signs, and in healthy persons drinking alcohol occasionally in moderate quantities who served as the control group. The enzyme activity was determined by the spectrofluorometric method using 4-methylumbelliferone derivative as substrate. The activity of beta-hexosaminidase in both groups with liver disease of both alcoholic and non-alcoholic origin exceeded significantly the control values. In those alcohol-dependent patients with liver disease who did not stop drinking, the activity was higher after recent drinking in relation to that after a period of abstinence. The determination can thus serve as a marker of alcohol abuse also in alcohol-dependent patients with liver damage. The share of thermostable component in the total increase of beta-hexosaminidase activity in alcohol-abusing persons was higher than that in the case of hepatic diseases of non-alcoholic origin.
