CDI4 is a monocyte/polymorphonuclear cell receptor for lipopolysaccharide (LPS)-LPS Binding Protein (LBP), which mediates most of the toxic effects exerted by such a bacterial component in the host. Here, we provide evidence that sCD14 and interferon (IFN)-gamma serum levels are significantly higher in chronic hepatitis C (CH-C) patients than those detected in normal donors. On the other hand, CD4+/CD8+ antibacterial activity is depressed, thus facilitating entry of bacteria into the host. Of note, all these immune parameters are not modified by in vivo IFN-alpha administration over a period of one year. Finally, after 12 months of IFN-alpha treatment number of CH-C patients with detectable levels of plasmatic LPS increased, thus indicating a continuous release of LPS into the host and also suggesting a putative pathogenetic role for sCD14 LPS-LBP complex in subjects affected by CH-C virus infection.
