摘要:

目的 探讨血清白细胞介素33(IL-33)水平及其基因多态性与乙型肝炎病毒(HBV)感染临床转归之间的相关性。方法 选取HBV感染患者341例,其中自限性HBV感染者93例(自限性感染组)、无症状慢性HBV携带者91例(HBV携带组)、慢性乙型肝炎(CHB)患者90例(CHB组)、乙型肝炎相关肝硬化患者67例(肝硬化组)。检测所有患者丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、总胆红素(TB)、IL-33、IL-33基因rs10975519位点单核苷酸多态性及HBV DNA载量。采用Pearson相关分析评估IL-33与ALT、AST及TB的相关性。结果 自限性感染组、HBV携带组、CHB组、肝硬化组ALT、AST、TB及IL-33水平依次升高(P<0.05)。Pearson相关分析结果显示,IL-33水平与ALT、AST及TB水平均呈正相关(r值分别为0.447、0.459、0.512,P值分别为<0.001、<0.001、0.018)。根据各项指标的参考区间上限分别对CHB组及肝硬化组进行分组并比较血清IL-33水平。在CHB组中,HBV DNA>1×105者血清IL-33水平高于HBV DNA≤1×105者(P<0.05),ALT>40 U/L者与ALT≤40 U/L者之间、AST>40 U/L者与AST≤40 U/L者之间、TB>20 μmol/L者与TB≤20 μmol/L者之间血清IL-33水平差异均无统计学意义(P>0.05);肝硬化组中,HBV DNA>1×105者、ALT>40 U/L者、AST>40 U/L者及TB>20 μmol/L者血清IL-33水平分别高于HBV DNA≤1×105者、ALT≤40 U/L者、AST≤40 U/L者及TB≤20 μmol/L者(P<0.05)。各组IL-33基因rs10975519位点基因型及等位基因分布频率差异均有统计学意义(P<0.05)。TT基因型在自限性感染组中分布频率最高,肝硬化组最低;而TC及CC基因型在自限性感染组中分布频率最低,肝硬化组最高。结论 IL-33水平与HBV感染临床转归密切相关,IL-33基因rs10975519位点C等位基因可能会增加CHB进展为肝硬化的风险。

Abstract:

Objective To investigate the correlation between the level of serum interleukin 33(IL-33)and its gene polymorphism and the clinical outcome of hepatitis B virus(HBV) infection. Methods Totally,341 patients with HBV infection were enrolled,including 93 patients with self limited HBV infection(self limited infection group),91 asymptomatic chronic HBV carriers(HBV carrying group),90 patients with chronic hepatitis B(CHB)(CHB group) and 67 patients with hepatitis B related cirrhosis(liver cirrhosis group). The single nucleotide polymorphisms of alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TB),IL-33,IL-33 gene rs10975519 and HBV DNA load were determined. Pearson correlation analysis was used to evaluate the correlation between IL-33 and ALT,AST and TB. Results The levels of ALT,AST,TB and IL-33 increased successively in self limited infection group,HBV carrying group,CHB group and liver cirrhosis group(P<0.05). Pearson correlation analysis showed that the level of IL-33 was positively correlated with the levels of ALT,AST and TB(r values were 0.447,0.459 and 0.512,P<0.001,<0.001 and 0.018,respectively). According to the upper limit of the reference interval of each index,CHB group and liver cirrhosis group were classified,and the levels of serum IL-33 were compared. In CHB group,the level of serum IL-33 in patients of HBV DNA>1×105 was higher than that in patients of HBV DNA≤1×105P<0.05). There was no statistical significance in serum IL-33 levels among ALT>40 and ≤40 U/L,AST>40 and ≤40 U/L,TB>20 and ≤20 μmol/L groups(P>0.05). In liver cirrhosis group,the level of serum IL-33 in HBV DNA load>1×105,ALT>40 U/L,AST>40 U/L and TB >20 μmol/L patients was higher than that of HBV DNA load≤1×105,ALT≤40 U/L,AST≤40 U/L and TB≤20 μmol/L patients(P<0.05). There was statistical significance in genotype and allele distribution frequency of rs10975519 of IL-33 gene in each group(P<0.05). The distribution frequency of TT genotype was the highest in self limited infection group,and it was the lowest in liver cirrhosis group. The distribution frequencies of TC and CC genotypes were the lowest in self limited infection group,and they were the highest in liver cirrhosis group. Conclusions The level of IL-33 is related to the clinical outcome of HBV infection. The C allele at rs10975519 of IL-33 gene may increase the risk of CHB progression to liver cirrhosis.
