Conclusion
IL-4, IL-17 and CD163 were associated with HCV severity. Their expression in HCC suggests their important role in HCC development. Blocking of these proteins may be a good target to control inflammation in HCV and can hinder progression to cirrhosis then to HCC. On the other hand, IL6-572 promoter gene polymorphism is neither associated with HCV infection nor with HCC development and its progression.<br />.
Methods
Sixty HCC specimens and 60 adjacent hepatic tissue with HCV of different grades of necro-inflammation and different stages of fibrosis. In addition to 55 HCV, 60 HCC and 50 healthy venous blood samples for evaluation of IL6-572 C/G gene polymorphism.
Objective
To assess the expression of IL-4, IL-17 and CD-163 as well as study of IL6-572 C/G gene polymorphism in chronic HCV and HCC on top of HCV.
Results
high expression of IL-4, IL-17 and CD163 in higher grades of activity, late stages of fibrosis and higher degrees of steatosis of HCV. IL-4 and CD163 showed higher expression in advanced grades of HCC, while IL-17 more expressed in lower grades. No significant difference in IL6-572 C/G gene polymorphism among studied groups regarding G/C, G/G, C/C frequencies or G and C allele's frequencies.
