[Five-year follow-up of clinical and laboratory data of early liver cirrhosis patients confirmed by liver biopsy].

BACKGROUND/AIMS: It is important to evaluate the general status of the liver including the structural and inflammatory aspects, as well as the functional aspects, in order to determine a patient's treatment modality and prognosis. METHODS: 55 Child-Pugh class A liver cirrhosis patients confirmed by liver biopsy have been categorized into 4 groups based on the shunt index and p-value(Y= 3.3431-0.8160 ALT/AST ratio-0.0343 X prothrombin time+2.6963 X shunt index, p = e(y)/(e(y)+1)), which was obtained by Thallium- 201 scan; group I - shunt index less than 0.3 and p-value less than 0.7; group II - shunt index less than 0.3 and p-value more than 0.7; group III - shunt index more than 0.3 and p-value less than 0.7; and group IV - shunt index more than 0.3 and p-value more than 0.7. Statistical analyses used were ANOVA, paired t-test, and Chi-square test. RESULTS: 1. The laboratory data after a 5-year follow-up also showed a significant difference between four groups. 2. In group IV, the Child-Pugh class after 5 years worsened, and complications of liver cirrhosis such as esophageal varix, ascites, and hepatic encephalopathy occurred more frequently. 3. In group II, the laboratory data after a 5-year follow-up indicated some improvement. CONCLUSION: It can be seen that even early in patients with initially the same cirrhosis, the course of the illness can progress to a variety of different situations. The measurement of shunt index and the p-value of cirrhosis will be more helpful in the follow-up evaluation and predicting its prognostic index in liver cirrhosis patients.

[Relationship of propranolol pharmacokinetic parameters with portosystemic shunt in CCl4-induced cirrhotic rats].

BACKGROUND/AIMS: This study was designed to determine the relationship of propranolol pharmacokinetic parameters with portosystemic shunt in CCl4-induced cirrhotic rats. METHODS: Cirrhotic rats(n=6) were induced by intramuscular injection of CCl4 in olive oil(two time per weeks) for 12 weeks. Controls (n=6) were injected intramuscularly with the same dose of olive oil for 12 weeks. We evaluated the amount of portosystemic shunt by thallium-201 per rectal scintigraphy. After intravenous bolus injection of propranolol (2mg/kg) to rats, the serum propranolol concentrations were analyzed by a HPLC-fluorimetric detector system. Pharmacokinetic parameters such as C0, AUC, t1/2(beta), and CLp were determined in each group. Then, a small amount of heptic tissue was obtained and subjected to determination of the hepatic collagen content by quantitating 4-hydroxyproline and were inspected by microscope after hematoxylin and eosin stain. RESULTS: In liver biopsy, liver fibrosis progressed in CCl4-induced cirrhotic rats. The serum concentrations of propranolol were significantly (p < 0.01) elevated in CCl4-induced cirrhotic rats. Mean amount of 4-hydroxyproline, mean H/L ratio, and mean AUC in CCl4-induced cirrhotic rats was significantly (p < 0.01) higher than that in control rats. There was a relationship between AUC, H/L ratio, and amount of 4-hydroxyproline. CONCLUSION: H/L ratio may help in the selection of drug dosage (especially blood flow dependent drug) in pre-clinical studies for chronic liver disease during the drug development process.
