More than 20 years after the discovery of the HCV, it is now well established that HCV is of global importance affecting all
countries, leading to a major global health problem that requires widespread active interventions for its prevention and
control. Chronic hepatitis C was linked to the development of cirrhosis and hepatocellular carcinoma (HCC) in many areas
of the world. WHO reported that Egypt has the highest prevalence (22%) in the world which explained by the past practice
of parenteral therapy for schistosomiasis. T cells that produce IL-17 have recently been identified as a third distinct subset of
effector T cells, and emerging data implicate Th17 cells as important in the pathogenesis of chronic hepatitis C infection by
regulating innate and adaptive immunity, including autoimmunity. So the present study was conducted to determine the role
of IL-17, with its potent pro-inflammatory properties, among chronic hepatitis C cases with or without cirrhosis and HCC
aimed at future immune-therapy. The study was conducted on 60 subjects with chronic hepatitis C infection before starting
antiviral therapy; 20 chronic hepatitis C, 20 cirrhotic patients and 20 HCC HCV positive as well as 10 healthy subjects negative
for HCV, HBV and HIV served as controls. IL-17 was quantitated after mitogen stimulated whole peripheral venous blood by
commercial enzyme linked immunosorbant assay (ELISA).Our results demonstrated a significant increase in serum levels of
IL-17 among cirrhotic and HCC patients infected with HCV. While in chronic hepatitis C virus cases, elevated IL-17 values were
non-significant compared to controls. It can be conclude that IL-17may play an important role in HCV immunopathogenesis.
It might be used as an indicator for cirrhosis and HCC as it promotes tumor growth by facilitating angiogenesis in tumor
microenvironment. Also, its therapeutic application needs to be furtherly evaluated by in vivo studies in experimental animals
aiming at future immunotherapy.
Keywords: Chronic HCV, Cirrhosis, ELISA, HCC, Interleukin (IL )-17, T-helper 17 cell (Th17).
