High levels of serum-soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) have been noted in patients with chronic hepatitis C. This study aimed to measure serum levels of sICAM-1 and sVCAM-1 in asymptomatic hepatitis C virus carriers and clarify the clinical significance of measuring soluble forms. Serum levels of sICAM-1 were significantly higher than in healthy controls but serum sVCAM-1 levels did not differ statistically from those in healthy controls. Liver biopsy obtained from 12 asymptomatic hepatitis C virus carriers showed evidence of hepatitis. Estimating sICAM-1 and sVCAM-1 in asymptomatic carriers may be helpful, especially in cases in which liver biopsy is not possible.
