The chronic viral hepatitis C is widely prevalent disease with prolonged persistence of virus and obliterated clinical picture. The present techniques of diagnostic of degree of fibrosis of liver and prognosis of course of disease have particular shortcomings. Hence, search of safe low invasive methods based on blood biomarkers is an actual task. The cytokines/chemokines (mediators of chronic inflammation) directly involved into immunopathogenesis of chronic viral hepatitis C can act in the capacity of biomarkers. The study was carried out to comprehensively analyze content of cytokines/chemokines in peripheral blood of patients with chronic viral hepatitis C at various stages of disease and infected by different genotypes of virus of hepatitis C. The concentration of cytokines/chemokines was identified in blood plasma of patients with chronic viral hepatitis C (n = 73) and conditionally healthy donors (n =3 7): IFNα, IFNγ, IFNλ/IL28α, TNFα, CCL2/MCP-1, CCL3/MIP-lα, CCL4/MIP-lβ, CCL5/RANTES, CCL8/MCP-2, CCL20/AIP-3α, CXCL9/MIG, CXCL10/P-10, CXCLII/ITAC. The multiplex analysis using technology xMAP was applied. The increasing of level of TNFα, CCL2/MCP-1, CCL4/ MIP-l, CCL8/ACP-2, CCL20/MIP-3α, CXCL9/MIG, CXCL10/IP-10, CXCL11/ITA C was established in blood plasma of patients with chronic viral hepatitis C as compared with control group. The levels of analyzed interferons IFNα, IFNγ, IFNλ/IL28α had no difference in studied groups. As far as chronic viral hepatitis C progresses and fibrosis of hepatic tissue develops the concentrations of TNFα, CCL2/MCP-1, CCL20/MIP-3α, CXCL9/MIG, CXCL10/IP-l0, CXCL11/ITAC increased significantly. The concentrations of chemokine CXCL11/IT4 C can be used as informative indicator for differentiating diagnostic of early stages of liver fibrosis. Depending on genotype of virus of hepatitis C, in patients with chronic viral hepatitis C change in content of CCL8/MCP-2 was established. Hence, detection in blood plasma of patients with chronic viral hepatitis C concentration of particular cytokines/chemokines using multiplex analysis technique permit analyzing additional information concerning degree of liver fibrosis, activity of process of damage of hepatic tissue under chronic viral hepatitis C that indicates indirectly on genotype of virus of hepatitis C.
