【摘要】:目的探讨不同HCV基因分型与丙型肝炎肝硬化患者血清中白细胞介素(IL)17、IL-6及维生素D的关系。方法选取2012年1-12月解放军第三〇二医院收治的76例丙型肝炎肝硬化患者,根据基因型不同分为1b型47例和2a型29例。采用ELISA法检测患者血清中IL-17、IL-6及维生素D水平。计量资料组间比较采用t检验,计数资料组间比较采用χ2检验,采用Spearman分析血清中IL-17、IL-6及维生素D与基因分型的相关性。结果在Child-Pugh改良分级结果中,1b型患者中A级所占比例相对于2a型差异具有统计学意义(χ2=4.97,P<0.05);1b型患者的AFP、HCV RNA滴度、IL-17、IL-6、TNF α均高于2a型,差异均有统计学意义(t值分别为2156、16.51、12.31、10.71、7.23,P值均<0.05),而IFN γ、25-OH-D、1,25(OH)2D低于2a型,差异均有统计学意义(t值分别为3.98、6.32、4.88,P值均<0.05);Spearman相关性分析发现,AFP、HCV RNA滴度、IL-6、IL-17与1b型、2a型基因均呈正相关(P值均<0.05),而IFNγ、TNFα和25-OH-D与1b型、2a型基因呈负相关(P值均<0.05)。结论1b型患者血清中IL-17、IL-6、AFP及HCV RNA水平均高于2a型患者,而维生素D低于2a型患者,血清中IL-17、IL-6、25-OH-D、AFP及HCV RNA与基因分型有一定的相关性,而1,25(OH)2D则与基因分型无关。
【Abstract】:ObjectiveTo investigate the association between different hepatitis C virus (HCV) genotypes and serum interleukin-17 (IL-17), interleukin-6 (IL-6), and vitamin D in patients with HCV-related cirrhosis. MethodsSeventy-six patients with HCV-related cirrhosis, who were admitted to 302 Hospital of PLA from January to December, 2012, were enrolled in the study, and they were divided into type 1b group (n=47) and type 2a group (n=29) according to the genotypes. The levels of serum IL-17, IL-6, and vitamin D were determined by enzyme-linked immunosorbent assay. Comparison between the two groups was made by t test, and Spearman correlation analysis was used to investigate the association between serum IL-17, IL-6, and vitamin D and genotypes. ResultsThe findings in improved Child-Pugh classification showed that there were significant differences in the percentage of grade A patients between type 1b group and type 2a group (χ2=4.97, P<0.05); when compared with type 2a group, type 1b group showed significantly higher lentiviral titers of alpha-fetoprotein (AFP) and HCV RNA and levels of IL-17, IL-6, and tumor necrosis factor-α (TNFα) (t=21.56, 16.51, 1231, 10.71, and 7.23, respectively, all P<0.05), but significantly lower levels of interferon-γ (IFNγ), 25(OH)D, and 1,25(OH)2D (t=3.98, 6.32, and 4.88, respectively; all P<0.05); Spearman correlation analysis showed that the lentiviral titers of AFP and HCV RNA and the levels of IL-17 and IL-6 were positively correlated with genotype 1b and genotype 2a (all P<0.05), while the levels of IFNγ, TNFα, and 25-OH-D were negatively correlated with genotype 1b and genotype 2a (all P<0.05). ConclusionCompared with those with genotype 2a, HCV-related cirrhosis patients with genotype 1b have higher serum levels of IL-17, IL-6, AFP, and HCV RNA, but a lower level of vitamin D; the results suggested that there are correlations between serum IL-17, IL-6, 25-OH-D, AFP, and HCV RNA and genotype, but no significant correlation between 1,25(OH)2D and genotype.
