Brief Summary:
The purpose of this study is to determine whether patients with liver disease can improve their nutritional selenium status by taking supplemental selenium.

Condition or disease Intervention/treatment Phase
Healthy Liver Cirrhosis Drug: Selenium Supplements (essential nutrient) Not Applicable

Detailed Description:

Selenium is an essential nutrient. Selenium carries out its biological functions through selenoproteins. The most abundant selenoprotein in the plasma is selenoprotein P, which is largely synthesized in the liver. Patients with liver disease often have less than half the selenoprotein P levels of normal individuals. This suggests that people with liver disease are not meeting their selenium requirements and may benefit from additional selenium.

We proposed to compare the effects of two different forms of supplemental selenium on plasma selenium levels among patients with severe liver cirrhosis and healthy individuals (controls). Patients and controls were randomly assigned to one of 3 treatment groups: 200 µg selenium per day as selenate, 200 µg selenium per day as selenomethionine, or a placebo. The intervention lasted 8 weeks. Blood was measured initially and after 2 and 4 weeks of supplementation. Selenium, selenoprotein P and glutathione peroxidase were measured in the plasma. We compared changes in selenium and selenoprotein levels between liver cirrhosis patients and healthy controls.
