Background Chronic viral hepatitis is histologically characterized by predominantly periportal infiltration of mononuclear cells, including lymphocytes and monocytes/macrophages. Intralobular infiltration of these inflammatory cells is an ominous sign of deterioration and a criterion for disease activity. Objective To assess the monocyte inflammatory milieu, monocytes adhesion molecules, their endothelial receptors, cytokines and chemokines in patients with HCV induced chronic liver disease, in an attempt to clarify the role of blood monocytes in induction of inflammation and fibrogenesis in chronic hepatitis C liver disease. Subjects and Methods The current study included 60 patients with chronic liver disease categorized into 2groups: Patients chronic hepatitis C (CHC) and patients with liver cirrhosis (LC), 15 patients each; 15 healthy subjects were included as normal controls. Immunophenotype characterization was carried out by flowcytometric analysis for identification of CD11a, CD11b and CD49d monocyte surface antigen expression in different groups studied. The circulating levels of the soluble adhesion molecules (sE-selectin, sICAM-1 and sVCAM-1), cytokines (TNF-α and IL-1) and chemokines (MCP-1) were also assessed by immunoassays. Results Data demonstrated a significant increase (p |
