To provide fundamental insights into the mechanism of Hepatitis C virus (HCV), we conduct the present study to improve further understanding of the interaction between HCV and cytokines. Two hundred one patients were enrolled in this study. Seventy-eight patients matching the study group in terms of age and gender with negative serology for hepatitis viruses, HIV virus, and with liver enzyme levels within normal range were selected as the control group. Patients were diagnosed with positive hepatitis C by detection of positive HCV antibodies in serum. Interferon-gamma (IFN-γ) and interleukin (IL)-10 were measured in positive and negative patients. Also liver functions (alanine aminotransferase [ALT], aspartate aminotransferase [AST], gamma glutamyl transferase [GGT], alkaline phosphatase [ALP], urea, total protein, albumin, total and direct bilirubin) were also measured. Our results indicated significant elevation in IL-10 and IFN-γ in positive hepatitis C patients. These elevations were accompanied by significant elevation in liver function biomarkers with significant regression in albumin and total protein content. Furthermore, IFN-γ significantly increased immune response of cellular immunity. IL-10 significantly decreased immune response of cellular immunity by inhibiting IFN-γ and other production of Th. Liver function levels can be used as a marker for HCV. The findings from our study recommend IL-10 pathway in HCV infection and use IFNs to increase immune response for viral hepatitis.
