This study is looking at the detection of vasoactive peptides in portal hypertension.
Investigate vasoactive medicators in portal hypertension on stored sera
The purpose of this study is to learn whether timolol is useful in preventing or delaying the appearance of gastroesophageal varices, a complication that may develop in the future as a consequence of liver disease. Cirrhosis causes an increased resistance of blood flowing through the liver. This leads to an increased pressure in the portal vein (the vein that takes blood to your liver). High portal pressure is responsible for the appearance of complications of chronic liver disease such as varices and variceal bleeding (bleeding from veins in your esophagus). Timolol belongs to a group of medications called beta-blockers. Beta-blockers decrease high portal pressure and previous studies have shown that beta-blocker pills are useful in preventing bleeding from varices in patients who already have varices. A more desirable effect would be if these pills could prevent not only bleeding from varices but the appearance of varices (and therefore of bleeding).
OBJECTIVES: I. Assess the effect of lactulose on the circadian rhythm of plasma melatonin in patients with subclinical hepatic encephalopathy. II. Assess the intrasubject variability of circadian melatonin levels and neuropsychological tests. III. Assess which elements of the neuropsychological test battery show the response to lactulose.
