Impact of IL-6 and IL-6r variants on HIV-1 susceptibility and progression to AIDS: a case-control study in a Moroccan population. NUCLEOSIDES, NUCLEOTIDES & NUCLEIC ACIDS 2024:1-20. [PMID: 38830242 DOI: 10.1080/15257770.2024.2359593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 05/16/2024] [Indexed: 06/05/2024]
Abstract
Interleukin-6 (IL-6), a pro-inflammatory cytokine, is an important regulator of the inflammatory immune response. We aimed to assess the association of common single nucleotide polymorphisms (SNPs) in IL-6 (rs1800795 G > C, rs1800797 A > G) and interleukin-6 receptor (IL-6R) (rs2228145 A > C) genes with HIV-1 infection, AIDS progression, and response to treatment. In this case-control study involving 199 individuals living with HIV-1 and 200 HIV-uninfected controls, we conducted genotyping of IL-6/IL-6R SNPs using TaqMan real-time PCR assays. Soluble IL-6 levels were measured using ELISA. No associations were found between the investigated SNPs and HIV infection. However, a significant association was noted between the C-G and G-A haplotypes and susceptibility to HIV-1 infection. Additionally, a significant association was revealed between HIV-1 RNA viral loads and IL-6 SNP G > C in the post-treatment HIV group. Interestingly, we observed a significant association between the investigated SNPs and protection against progression to AIDS, namely the IL-6 G > A SNP in its recessive model and the IL-6R A > C SNP in its codominant and dominant models. Nevertheless, we found no significant differences between IL-6 levels and the different genotypes and alleles of the IL-6 gene either before or after combination antiretroviral therapy. IL-6 promoter haplotypes are associated with susceptibility to HIV-1 infection. Furthermore, IL-6 A > G and IL-6R A > C polymorphisms have been associated with protection against AIDS progression. Interestingly, the IL-6 G > C SNP may affect the response to treatment in people living with HIV-1.

Abstract
Chronic inflammation triggered by hepatitis B (HBV) and hepatitis C (HCV) viruses elevates interleukin 6 (IL-6) levels, activating pathways that cause liver damage and contribute to hepatocellular carcinoma (HCC) development. In this study, we assessed IL-6 levels and explored the correlation between the rs1800795 and rs1800797 variants of the IL-6 gene and the risk of developing HCC. We conducted a case-control study involving 314 participants. Among them, 157 were HCC patients (94 anti-HCV, 22 HBsAg and 41 metabolic dysfunction-associated steatotic liver disease [MASLD]) and 157 controls. Genotyping for IL-6 rs1800795 and rs1800797 polymorphisms was performed using real-time polymerase chain reaction (PCR). Additionally, plasma IL-6 levels were determined using enzyme-linked immunosorbent assay. The IL-6 levels were notably higher in patients compared to controls (p < .0001). Among HCC patients, those with MASLD exhibited higher plasma IL-6 levels than those with HCV and HBV (p = .003). In male HCC patients, IL-6 levels were significantly elevated compared to controls (p < .0001). Similarly, female patients showed significantly higher IL-6 levels compared to female controls, though still lower than in male HCC patients (p = .023). However, no significant difference was observed in IL-6 levels between male and female HCC patients (p = .129). Contrastingly, the genotype and allele distributions of the rs1800795 and rs1800797 polymorphisms in the IL-6 gene displayed no association with HCC development (all p > .005). In Moroccan HCC patients, chronic liver inflammation is characterized by elevated levels of IL-6, potentially playing a role in the progression of liver disease and tumourigenesis.

Abstract
Background The relationship between viral infections and host factors holds high hopes for identifying the role of Interferon Lambda 3 (IFNL3) and Interleukin 6 (IL-6) polymorphisms in the development of Chronic Liver Disease (CLD) in patients infected with hepatitis Delta virus (HDV) in the Western Brazilian Amazon. Methods Cross-sectional study conducted with a cohort of 40 chronic HDV patients, 27 with CLD and 13 without evident liver damage. Biological samples from the participants were analyzed using the polymerase chain reaction (PCR) technique, followed by sequencing by the automated Sanger method. Results The rs8099917 T allele, from the IFNL3 gene, showed a higher frequency in both groups; however, it was not possible to establish an association with HDV infection [OR = 1.42 (0.42 - 4.75; p = 0.556 (95% CI). For IL-6, the rs1800795 G allele was superior to rs1800795 C. Analyzing both distributions in the studied groups, any association with HDV was absent (p > 0.05). Conclusion The results suggest that the rs8099917 T/G (IFNL3) and rs1800795 G/C (IL-6) polymorphisms are not associated with the evolution of HDV in the studied population.

Abstract
Hepatitis B and C viruses (HBV and HCV) are common causative pathogens of viral hepatitis. Progression of both infections is determined by virus- and host-related factors. Cytokines are important host genetic factors that may have a predisposing role in HBV and HCV infections. This case-control study evaluated the genetic association of IL4RA+1902 (rs1801275), IL6-174 (rs1800795), IL6-597 (rs1800797), and IL12B-1188 (rs3212227) variants with chronic HBV and HCV infections among Iraqi patients. A total of 220 viral hepatitis patients were enrolled in the study (113 HBV and 107 HCV), together with 141 healthy subjects. Sequence-specific primer polymerase chain reaction assay was the genotyping method. Results revealed that under a dominant genetic model, IL6-174 variant was significantly associated with HBV infection, whereas no association with the HCV risk was reported. However, the risk for both infections was markedly associated with IL6-597 variant under recessive, dominant, and codominant genetic models. Estimation of IL6-174 -IL6-597 haplotypes depicted that G-A haplotype was significantly associated with an increased risk to develop HBV infection, whereas a significantly decreased risk was associated with G-G and C-G haplotypes. For HCV, G-G and C-A haplotypes were significantly associated with risk of HCV infection. IL4RA+1902 and IL12B-1188 variants showed no association with HBV or HCV risk. Analysis of variance revealed no significant association between genotypes of the four determined single-nucleotide polymorphisms and HBV or HCV viral load. In conclusion, the study supports the concept that IL6-597 variant is associated with susceptibility to HBV and HCV infections among Iraqis. The risk of HBV infection is further associated with IL6-174 variant.
