Purpose of the study. To study lipid metabolism in chronic hepatitis C and to assess its impact on the formation of insulin resistance, steatosis and progression of liver fibrosis.Materials and methods. The study included 205 patients with chronic hepatitis C (CHC). Conducts research, depending on the genotype C, viral load and body mass index (BMI) of the patients.Results. CHC patients revealed a combined hyperlipoproteinemia on the background of op-pression synthesis of apolipoproteins A1 and B. Formation of hepatic steatosis was associated with HCV genotype 3 virus-induced viral load at ≥ 6 log10 IU/ml and metabolic in VL < 6 log10 IU/ml. In patients with chronic hepatitis C genotype 1, high viral load leads to inhibition of protein synthesis conveyor ApoA1 and increased synthesis of cholesterol, accompanied by abdominal obesity and the formation of insulin resistance. CHC patients with BMI < 25 kg/m2 viral load ≥ 6 log10 ME/ml was associated with dyslipidemia IV type on D. Fredriskson (1970), hyperglycemia, insulin resistance and diabetes. The advanced stage of liver fi brosis (F ≥ 3 on a scale METAVIR) and non-response to treatment were associated with a decrease in HDL cholesterol below normal. With an increase in viral load > 5 log10 ME/ml signifi cantly increased the risk of lipid and carbohydrate metabolism.

An inefficient immune response against the hepatitis C virus (HCV), combined with viral evasion mechanisms, is responsible for the chronicity of infection. The need to evaluate the innate mechanisms of the immune response, such as TLR3 and IFN-λ3, and their relationship with the virus–host interaction is important for understanding the pathogenesis of chronic hepatitis C. The present study aimed to investigate the gene expressions of TRL3 and IFNL3 in liver tissue, seeking to evaluate whether these could be potential biomarkers of HCV infection. A total of 23 liver biopsy samples were collected from patients with chronic HCV, and 8 biopsies were collected from healthy control patients. RNA extraction, reverse transcription and qPCR were performed to quantify the relative gene expressions of TLR3 and IFNL3. Data on the viral load; AST, ALT, GGT and AFP levels; and the viral genotype were collected from the patients′ medical records. The intrahepatic expression of TLR3 (p = 0.0326) was higher in chronic HCV carriers than in the control group, and the expression of IFNL3 (p = 0.0037) was lower in chronic HCV carriers than in the healthy control group. The expression levels of TLR3 (p = 0.0030) and IFNL3 (p = 0.0036) were higher in the early stages of fibrosis and of necroinflammatory activity in the liver; in contrast, TLR3 and IFNL3 expressions were lower in the more advanced stages of fibrosis and inflammation. There was no correlation between the gene expression and the serum viral load. Regarding the initial METAVIR scale scores, liver transaminase levels were lower in patients with advanced fibrosis when correlated with TLR3 and IFNL3 gene expressions. The results suggest that in the early stages of the development of hepatic fibrosis, TLR3 and IFN-λ3 play important roles in the antiviral response and in the modulation of the tolerogenic liver environment because there is a decrease in the intrahepatic expressions of TLR3 and IFNL3 in the advanced stages of fibrosis, probably due to viral evasion mechanisms.
