This review summarizes our current knowledge on the innate and adaptive immune responses induced by hepatitis C virus, and on the genetic polymorphisms that may determine the outcome of the disease. In addition, the authors discuss the role of reactive oxygen species and oxidative stress in hepatitis C virus-related pathogenic processess, such as hepatitis, fibrosis, hepatocellular carcinoma, steatosis and insulin resistance.

The paper is devoted to an analysis of the problem of the significance and mechanisms of inflammation and oxidative stress participation in the development of cardiovascular pathology, first of all – in heart and vascular wall damaging and remodeling and in the development of arterial hypertension. An interrelation is traced between the reninangiotensin, sympathoadrenal and immune systems in the development of oxidative stress as a component of innate and adaptive immune responses.

Background: Cytokines and chemokines are critical regulators of innate and adaptive immunities during viral infection. We examined innate and adaptive immune responses to hepatitis C virus (HCV) and hepatitis B virus (HBV) at baseline and against controls. Methods: Twenty-seven cytokines were evaluated before treatment in 27 patients with chronic hepatitis C(CHC) [genotype1 (n=20), genotype2 (n=7), HCVRNA 5.72IU/ml] and 12 chronic hepatitis B(CHB) [e-antigen (Ag) (+) (n=5), e-Ag (-) (n=7), HBVDNA 6.191.31Logcopies/ml] and against controls(n=5). Results: Th1 and Th2 cytokines were significantly higher (p<0.05) in CHB than in CHC. The levels of IL-IL10 in CHC and CHB, and IL15 in CHC(genotype2) and CHB were significantly lower (p<0.05) than in controls. The levels of CXCL8 in CHC and CHB, IL12 in CHC and CHB [e-Ag (-)] and CXCL10 in CHC and CHB were significantly higher (p<0.05) than in controls. IFN-γwas higher in CHB than in controls. Conclusion: Cytokines levels differed between CHB and CHC before treatment. Innate immune responses were impaired in CHB with HBeAg(-) and CHC, but not in CHB with HBeAg(+) with high viral loads. Adaptive immune responses were impaired in CHB and CHC and appear to reflect the distinct state of virus-host immune interactions between CHB and CHC.
