The Genetic Profile and Serum Level of IL-8 Are Associated with Chronic Hepatitis B and C Virus Infection
The present study evaluated the <i>IL8</i>-251 A/T polymorphism in samples from 74 patients with chronic hepatitis B (HBV), 100 patients with chronic hepatitis C (HCV), and 300 healthy donors (CG). The correlations of this polymorphism with plasma IL-8 and disease stage were calculated....

The correlations of this polymorphism with plasma IL-8 and disease stage were calculated. Polymorphisms were identified by real-time PCR. IL-8 was measured by enzyme-linked immunosorbent assay. The <i>IL8</i>-251 A/T genotype was not associated with susceptibility to infection by HBV or HCV. The wild-type allele (A) was associated with higher levels of inflammation (<i>p</i> = 0.0464) and fibrosis scores (<i>p</i> = 0.0016) in the HBV group, representing an increased risk for increased inflammatory activity (<i>OR</i> = 1.84; <i>p</i> = 0.0464) and for high fibrosis scores (<i>OR</i> = 2.63; <i>p</i> = 0.0016). Viral load was higher in HBV patients with polymorphic genotypes (TA and TT) at the <i>IL8</i>-251 A/T polymorphism than in those with the wild-type genotype (<i>p</i> = 0.0272 and <i>p</i> = 0.0464, respectively). Plasma IL-8 was higher among patients infected with HBV or HCV than in the control group (<i>p</i> = 0.0445 and <i>p</i> = 0.0001, respectively). The polymorphic genotype was associated with lower IL-8 than the wild-type genotype in the HBV group (<i>p</i> = 0.0239) and the HCV group (<i>p</i> = 0.0372). The wild-type genotype for <i>IL8</i>-251 A/T and high IL-8 were associated with a worse prognosis for infections; therefore, they may contribute to viral persistence and the development of more severe forms of chronic viral liver diseases.Ednelza da Silva Graça AmorasWilliam Botelho de BritoMaria Alice Freitas QueirozSimone Regina Souza da Silva CondeIzaura Maria Vieira Cayres VallinotoRicardo IshakAntonio Carlos Rosário VallinotoMDPI AGarticleHBVHCVIL-8polymorphismplasma levelsMicrobiologyQR1-502ENBiomolecules, Vol 11, Iss 1664, p 1664 (2021) |
