Serum cholinesterase activity (ChE) was studied in 84 patients with chronic liver diseases (cirrhosis, chronic hepatitis, chronic cholecystocholangiohepatitis, hepatolenticular degeneration). Most pronounced alterations were found in cirrhosis. Significant difference is not established between cardiac and "noncardiac" cirrhosis but is well established between decompensated and compensated cirrhosis. As a rule ChE is normal in chronic hepatitis and cholecystocholangio-hepatitis. The values in agressive and persisting hepatitis do not differ significantly. Essential correlation of ChE with serum albumins is established. The diagnostic ChE value is confronted with that of the routine laboratory indices. Critical values are established (1500 ME, 1100 ME resp) that may be helpful in the differentiation of cirrhosis from chronic hepatitis, compensated from decompensated cirrhosis resp.

The levels of C3, cholinesterase, albumin and prothrombin were determined in 46 patients (27 males and 19 females) - 26 with cirrhosis of the liver, 9 with acute hepatitis, 6 with chronic aggressive hepatitis, 1 with chronic persistent hepatitis and 4 with fatty liver. In all patients and, particularly in those with cirrhotic liver, it was shown that the normal or pathological level of serum C 3 is related both qualitatively and quantitatively to the normal or pathological levels of cholinesterase, albumin, and prothrombin. The percentage in which the levels of these four parameters were pathological was considerably higher in the cases with hepatic coma than in the cases without hepatic coma. The determination of the range of confidence for the 4 parameters showed that, in the patients with hepatic coma, cholinesterase reacted most sensitively to liver damage (0.5 - 0.94) followed by C3 and prothrombin (0.33 - 0.81). Also in the cases without hepatic coma, cholinesterase was the most sensitive indicator (0.05 - 0.29), followed by prothrombin (0.03 - 0.24), albumin and C3 (0.00-0.16).

The liver and spleen volume ratio (S/L ratio) was estimated with X-ray computed tomography. Clinical usefulness of S/L ratio was evaluated by comparison with other liver functions (retention rate of ICG, total bilirubin, serum albumin and cholinesterase activity) in 42 hepatocellular carcinoma patients with liver cirrhosis. The correlation between S/L ratio and retention rate of ICG, total bilirubin, serum albumin or cholinesterase activity was good (r = 0.870, r = 0.719, r = -0.691, or r = -0.606, respectively p less than 0.001). Positive correlation was observed between S/L ratio and retention rate of ICG or total bilirubin. Negative correlation was observed between S/L ratio and serum albumin or cholinesterase activity. In conclusion, the measurement of S/L ratio on computed tomography was considered to be useful as an evaluation for the degree of severity in liver cirrhosis by considering both effective hepatic blood flow and portal hypertension.

From April 1978 through December 1989, a total of 17 patients with unresectable hepatocellular carcinoma (HCC) were treated with radiation therapy alone or radiation therapy in conjunction with percutaneous ethanol injection (PEI), transarterial infusion chemotherapy (TAI), or transarterial embolization (TAE) at the National Medical Center Hospital. The median survival of all patients was 13.8 months. The survival values determined at 1, 2, and 3 years were 58.8%, 26.1%, and 9.8%, respectively. Only the pretreatment liver function affected the survival value. Between patients who did not have liver cirrhosis (LC) as well as those who had LC of Child's class A and patients who had LC of Child's class B or C, the differences observed in the 1-year survival value and the median duration of survival were statistically significant (P < 0.05). The serum cholinesterase (ChE) level seemed to be a good indicator of liver function during the radiation therapy. A field size of 150 cm2 and a total dose of 5000 cGy (TDF 82) seemed to be well tolerated by patients who did not have LC and those who had LC of Child's class A. The field size determined whether patients with poor liver function such as LC of Child's class B or C would develop severe hepatic deterioration after undergoing radiation therapy.

The concentration of plasma vitronectin was determined and compared with various parameters of liver function including the blood coagulation system in patients with liver diseases. The severity of cirrhosis was graded according to Child's criteria and compared with the plasma vitronectin level. Furthermore, the distribution of vitronectin in the liver of patients with liver diseases was studied by light and electron microscopy using the indirect immunoperoxidase method. The plasma vitronectin level was low in all liver disease groups as compared with the healthy controls. The difference from the controls was significant in patients with hepatocellular carcinoma and decompensated cirrhosis. Moreover, the plasma vitronectin level was positively correlated with the levels of serum cholinesterase, albumin, plasma alpha 2 plasmin inhibitor-plasmin complex and the prothrombin time and results of the hepatoplastin test. Plasma vitronectin decreased with increasing severity of cirrhosis according to Child's criteria. These results suggest that the plasma vitronectin level is a useful parameter of hepatic synthetic function in patients with liver diseases; it may also reflect the severity of cirrhosis. Light microscopy revealed vitronectin in the area of focal necrosis and the portal tracts in the liver of patients with acute viral hepatitis, in the area of piecemeal necrosis in the liver of patients with chronic hepatitis and along the area of fiber deposition in the liver of patients with cirrhosis. Immunoelectron microscopy showed vitronectin in the rough endoplasmic reticulum of hepatocytes. Moreover, vitronectin was seen around inflammatory cells, endothelial cells, Ito cells and hepatocytes in the perisinusoidal area near focal necrosis and piecemeal necrosis and on collagen fibers.(ABSTRACT TRUNCATED AT 250 WORDS)

Various liver function tests were evaluated in regard to a quantitative estimation of the impairment of liver function related to the Child-Pugh classification in 32 patients with cirrhosis. Only the ICG-test revealed significant differences between healthy subjects and cirrhotic patients in stadium Child A, B and C. When ICG-dye retention values were plotted as a function of the individual score units of the Child-Pugh classification, a linear relationship with a correlation coefficient of 0.7 was obtained. In contrast to the ICG-test, the MEGX- and galactose elimination capacity (GEC)-test as well as static parameters of liver function (cholinesterase activity, prealbumin concentration, coagulation factor V and VII) resulted in less significant differentiation of the various Child classes. The MEGX-test, GEC, concentration of prealbumin, coagulation factor V and VII were only weakly correlated to the score units of the Child-Pugh index. The results of this study indicate that of all evaluated parameters only the ICG-test is suitable for objective and graduated analysis of liver function in patients with cirrhosis.

We determined serum growth hormone-binding protein (GHBP), insulin-like growth factor-I (IGF-I), and growth hormone (GH) levels in patients with cirrhosis and in age-matched control subjects, and investigated their relationships. Serum GHBP levels in cirrhotic patients (14.6% +/- 3.9%) (means +/- SD) were significantly lower than those in normal subjects (20.4% +/- 4.7%). GHBP levels had positive correlations with cholinesterase (r = .58, P less than .001) and Normotest (r = .66, P less than .001), both of which represent liver function in cirrhotic patients. Basal GH levels in cirrhotic patients (range, 0.35 to 13.0 micrograms/L; median, 3.9 micrograms/L) were significantly higher than those in normal subjects (0.015 to 6.0 micrograms/L; 0.19 microgram/L). GHBP levels in cirrhotic patients correlated positively with IGF-I levels (r = .39, P less than .01), and negatively with GH levels (r = -.33, P less than .01). These results may indicate that the serum GHBP level reflects the number of hepatic GH receptors, and that the high basal GH level observed in cirrhotic patients is, at least in part, attributable to decreased clearance of GH by these receptors.

Indirect measurement of portal pressure and hepatic venography using the balloon catheter technique were investigated to assess the stage of chronic alcoholic liver disease, especially, to diagnose cirrhoses. 80 patients were studied and were categorised in 4 groups according to their liver histology: normal liver (N, n = 6), fibrosis (F, n = 27), incomplete cirrhosis (F/C, n = 11), complete cirrhosis (C, n = 36). Medians of wedged hepatic venous pressure gradient P (= WHVP-FHVP) and of a semiquantitative venographic score S showed increasingly higher values with more severe stages of the disease. Portal pressure (P) and venographic appearance (S) were correlated significantly (r = 0.778, p less than 0.0001). P was most useful to diagnose cirrhosis: Precirrhotic forms were associated with pressure gradients P less than or equal to 5 mm Hg in 97%. Incomplete cirrhoses were distributed in about 50% above and below P = 5 mm Hg, for complete cirrhoses P greater than or equal to 8 mm Hg was found in 97%. Pressure gradients P greater than or equal to 5 mm Hg indicated cirrhotic disease with a specificity of 97%. Sensitivity for complete cirrhoses was also high (97%), for incomplete cirrhoses however low (47%). Venography and measurement of portal pressure as diagnostic tools to predict cirrhoses of alcoholic origin were clearly more useful than biochemical tests (serum bilirubin, quick and cholinesterase). In comparison to laparoscopy the acceptance by patients is higher and the risk is lower if patients with known adverse reactions to contrast materials and risk of thyreotoxicosis induced by iodine are excluded.

A 64-year-old man was admitted to our hospital because of possible liver cirrhosis. His serum cholinesterase was anomalously low with a delta pH of 0.1 (normal range; 0.8-1.1). His enzyme was more heat-labile than the normal controls. Km value of his enzyme for benzoylcholine was 1.1 x 10(-5) mol/l, while that for normal controls was 2.3 x 10(-6) mol/l. In addition, isozymic alteration of his enzyme was observed. Sequencing of the white blood cell DNA of the patient showed a point mutation at nucleotide 1093 (GGA to CGA), which changes codon 365 from glycine to arginine.

To evaluate abnormal secretion of growth hormone (GH) in cases of liver diseases, the authors performed a loading test of growth hormone-releasing factor (GRF) and approximately one week later, a loading test of thyrotropin-releasing hormone (TRH), and measured serum GH in 15 cases of liver cirrhosis (LC), 5 with chronic active hepatitis (CAH), and 5 controls. In the TRH test, 8 of 15 LC patients showed a peak GH value of 6 ng/ml or more and were classified as the TRH-responder group (LC-R). Seven other LC patients showing a peak GH value of less than 6 ng/ml were classified as the TRH-non-responder group (LC-NR). None of the CAH cases or controls showed a peak GH value of 6 ng/ml or more. In GRF test, the response of GH was poor in all 8 in the LC-R group. The responses in the LC-NR group were significantly greater than those in the LC-R group from 15 to 90 minutes after the GRF loading. In the LC-R group, greater impairment of liver function was indicated by total bilirubin, serum protein and cholinesterase values compared to the LC-NR group. Fischer's ratio was significantly lower in the LC-R group. In cases of liver diseases, Fischer's ratios negatively correlated with the peak GH values in the TRH test (r = -0.679, P less than 0.01). These results suggest that in LC cases showing a paradoxical GH response to TRH, the GH response to GRF which is a GH stimulatory hormone, is decreased.(ABSTRACT TRUNCATED AT 250 WORDS)
