Abstract:
Objective:To investigate the correlation between interleukin-6 (IL-6) single nucleotide polymorphism (SNP) and the occurrence and prognosis of hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF).
Methods:Patients with chronic hepatic diseases diagnosed as HBV infection in the Hepatology Center of the First Affiliated Hospital of Fujian Medical University from July 2012 to March 2018 were divided into HBV-ACLF and non-ACLF group. SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) was determined by the improved multi-temperature ligase detection reaction (imLDRTM) technique. Simultaneously, case data were reviewed with the 3-months followed up survival condition of the ACLF group. Normally distributed data were expressed as arithmetic means and SDs, and t-test was adopted. Data with skewed distribution were expressed as medians with interquartile range, and were measured by non-parametric test. Multivariate logistic regression analysis was used to analyze the relative risk of genetic polymorphism and HBV-ACLF as well as the relationship between IL-6 SNPs with the occurrence and prognosis of HBV-ACLF.
Results:Four hundred patients were included in the study, with 122 (30.5%) in the HBV-ACLF and 278 (69.5%) in the non-ACLF group. There were significant differences in total bilirubin, albumin, and white blood cell count, percentage of neutrophils, platelet count, alanine aminotransferase, aspartate aminotransferase, prothrombin time and international standardized ratio, creatinine and the model for end-stage liver disease score between the two groups (P < 0.001). The genotype of IL-6 genes (rs1800795, rs1800797, rs2069827, and rs2069830) of all subjects showed no mutation or the mutation rate under 1%. There was no significant difference in the genotype of IL-6 (rs1524107, rs2069837, rs2069840 and rs2069845) between the two groups (P > 0.05). Multivariate logistic regression analysis showed that the SNPs in the above four loci of IL-6 gene was not associated with HBV-ACLF risk, nor had significant correlation with the 3-months prognosis.
Conclusion:The SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) is unrelated to the occurrence and short-term prognosis of HBV-ACLF.
