Serum Selenium Levels in Korean Hepatoma Patients
The aim of this study was to determine serum selenium (Se) levels during the development of liver disease as well as the possible Se supplementation benefits in liver disease patients. Serum was collected from 187 patients with liver diseases and 120 normal healthy people living in Seoul. The samples were collected at the Kangnam St. Mary’s Hospital College of Medicines, The Catholic University of Korea, in accordance with procedures approved by the Institutional Review Board of the Catholic University of Korea. Serum Se levels were quantified by inductively coupled plasma mass spectrometry and were compared between healthy and liver diseases patients. Se levels were 92.65 ± 32.50 μg/l in hepatitis infection, 92.33 ± 30.66 μg/l in hepatitis B virus infection and 96.41 ± 51.50 μg/l in hepatitis C virus infection, 96.42 ± 32.80 μg/l in cirrhosis, and 67.47 ± 14.30 μg/l in hepatoma patients. Findings were significantly lower in hepatitis and hepatoma as compared with the healthy participants (P < 0.001). The Se level of the healthy population was 108.38 ± 29.50, 119.37 ± 28.31 for males and 97.87 ± 26.99 μg/l for females. Our data shows the same parallelism between liver disease progression and decrease of Se levels except in the case of liver cirrhosis. And also, our study confirms the previous findings of significantly lower Se levels in Korean hepatoma patients. Se levels that decrease parallel to liver disease progression should be further integrated and analyzed with liver function blood biomarkers.
