摘要: 目的 探讨HBV相关慢加急性肝衰竭患者外周血调节性T淋巴细胞(Treg)、辅助性T淋巴细胞(Th)17细胞表达特点及其与HBV前C区/BCP区变异的相关性。方法 选择HBV相关慢加急性肝衰竭和肝衰竭前期患者各41例,采用ELISA 检测外周血IL-17、TGF-β1、IFN-γ、IL-1β及IL-21水平,流式细胞术检测Treg和Th17表达水平,直接测序法检测HBV前 C 区及BCP区基因,统计学处理用t检验。结果 肝衰竭患者Treg、Th17、IL-17、TGF-β1、IFN-γ、IL-1β水平、HBV变异位点中A1762T/G1764A双突变、G1896A突变比例分别为(9.28±1.12)%、(0.23±0.05)%、(151.83±35.22) pg/mL、(153.24±34.15) pg/mL、(177.61±29.25) pg/mL、(77.46±13.15) pg/mL、22/19、23/18,均高于肝衰竭前期患者的(7.47±0.74)%、(0.19±0.03)%、(134.02±34.39) pg/mL、(130.76±35.13) pg/mL、(130.68±22.87) pg/mL、(60.12±15.67) pg/mL、13/28、12/29,差异均有统计学意义(t’值分别为8.594、4.609、2.316、2.939、8.094、5.429,χ2值分别为4.038、6.032,均P<0.05);而Treg/Th17比值、IL-21水平在两组中差异无统计学意义(t=0.902,P=0.370;t=0.294,P=0.769)。HBV BCP区A1762T/G1764A双突变和G1896A突变的患者Treg、Th17水平均高于野生型,差异有统计学意义(t=2.932,P=0.004;t=2.339,P=0.022;t=3.232,P=0.002;t’=2.990,P=0.004),而Treg/Th17比值在突变型和野生型中差异均无统计学意义(t=0.030,P=0.976;t’=0.272,P=0.787)。结论 Treg细胞及Th17细胞变化,HBV BCP区A1762T/G1764A双突变、G1896A突变可能与HBV相关慢加急性肝衰竭相关。

Abstract: Objective To investigate the expression characteristics of peripheral T regulatory cell (Treg) and T help cell 17 (Th17) in patients with hepatitis B related acute-on-chronic liver failure (HBV-ACLF), and their correlation with HBV pre-C/BCP mutations.Methods Forty-one HBV-ACLF patients and 41 early ACLF patients were enrolled. Levels of serum interleukin (IL)-17, transforming growth factor (TGF)-β1, interferon (IFN)-γ, IL-1β and IL-21 were determined using enzyme-linked immuno sorbent assay (ELISA). Expression of Treg and Th17 were determined using flow cytometry. Sequencing for mutations of HBV pre-C/BCP region was performed. Results Levels of Treg, Th17, IL-17, TGF-β1, IFN-γ and IL-1β, A1762T/G1764A double mutations and G1896A mutation were significantly higher in HBV-ACLF patients than those in early HBV-ACLF patients (t' = 8.594, P<0.001; t = 4.609, P<0.001; t=2.316, P=0.023; t=2.939, P=0.004; t=8.094, P<0.001; t=5.429,P<0.001; χ2=4.038, P=0.044; χ2=6.032, P=0.01), respectively. There were no significant difference in the ratio of Treg/Th17 and IL-21 level between HBV-ACLF and early HBV-ACLF group (t=0.902, P=0.370; t=0.294, P=0.769). Treg and Th17 levels in patients with A1762T/G1764A double mutations or G1896A mutation were both significantly higher than those with no mutations (t=2.932, P=0.004; t=2.339, P=0.022; t=3.232, P=0.002; t'=2.990, P=0.004). There were no significant difference in the ratio of Treg/Th17 between mutation and non-mutation groups (t=0.030, P=0.976; t'=0.272, P=0.787). Conclusion Changes of Treg and Th17, A1762T/G1764A double mutations in HBV BCP region and G1896A mutation in pre-C region might play roles in pathogenesis of HBV-ACLF.
