RESUMO

@#Immune responses are largely regulated by cytokines. Genetic polymorphisms of the regulatory coding regions are recognized to impact the expression of cytokines. The abnormal cytokine levels in hepatitis C virus (HCV) infection seems to be involved in disease progression, viral survival, and therapeutic response. The current study assesses the polymorphisms associated with IL-6, IL-10, IL28B, IFN-γ, TGF-β, and TNF-α on the genotypic susceptibility to HCV infection and Ribavirin response to Peg interferon. Droplet digital polymerase chain reaction (PCR) was used to assess the gene polymorphisms associated with IL-6 A/G (rs2069837), IL-10-1082 G/A (rs1800896)], IL28B C/T (rs12979860), IFN-γ +874 A/T (rs2430561), TGF-β 1-509 C/T (rs1800469) and TNF-α-308 G/A promoter (rs1800629) from stored samples of 200 healthy individuals and 300 HCV infected patients. There was a significant association of AG and AA genotypes of IL28B, IFN-γ, TGF-β1, and TNF-α over HCV susceptibility and treatment outcome. However, no association between IL-6 and IL-10 gene polymorphism to HCV susceptibility response to the treatment. The observations indicate IL28B CT, TGF-β1 CT, TT and TNF- AG with AA genotypes influence the cytokine expression, which is related to susceptibility and resistance to HCV infection and combined antiviral therapy.
