Abstract
Aim: An ineffective immune response resulting from dysregulation of cytokine production might encourage viral persistence and cause chronic viral hepatitis to worsen. This study examined the relationship between alterations in interleukin-6 (IL-6) levels and the IL-6 - 174 G > C (rs1800795) polymorphism, as well as how this polymorphism affects the development and progression of chronic hepatitis brought on by hepatitis B (HBV) and hepatitis C (HCV) into hepatocellular carcinoma (HCC).
Patients and methods: Whole blood samples from 126 Egyptian patients with HCC (111 with HCV and 15 with HBV), as well as 126 age- and sex-matched healthy individuals, were used to extract DNA. Using PCR-based allele-specific amplification (ASA), the existence of the IL-6 G-174C polymorphism was investigated. Additionally, each participant's serum IL-6 levels were determined using an enzyme-linked immunosorbent assay (ELISA).
Results: The primary observations revealed that HCC patients had greater serum levels of IL-6 compared to the control groups (p < 0.001). Patients with the variant (CG and GG) genotype in the HCC group were found to have more disease severity indicated by higher levels of alpha-fetoprotein (AFP) and a higher ascites grade, as well as increased inflammatory activity as defined by higher levels of IL-6 and C-reactive protein (CRP) (p < 0.001 for both) in comparison to patients with the wild-type (CC) genotype (p < 0.001 and p = 0.002, respectively).
Conclusion: The rs1800795 SNP in the IL-6 gene was associated with increased inflammatory activity and high levels of IL-6, indicating that this SNP may play a role in the development of HCC in Egyptian patients with chronic viral hepatitis.
期刊介绍:
As the official publication of the National Cancer Institute, Cairo University, the Journal of the Egyptian National Cancer Institute (JENCI) is an open access peer-reviewed journal that publishes on the latest innovations in oncology and thereby, providing academics and clinicians a leading research platform. JENCI welcomes submissions pertaining to all fields of basic, applied and clinical cancer research. Main topics of interest include: local and systemic anticancer therapy (with specific interest on applied cancer research from developing countries); experimental oncology; early cancer detection; randomized trials (including negatives ones); and key emerging fields of personalized medicine, such as molecular pathology, bioinformatics, and biotechnologies.
