目的:探讨不同病因所致肝衰竭患者外周血单个核细胞(PBMCs)HLA-DR mRNA 及 Th17和CD4+CD25+Treg细胞水平的变化及其意义。方法本研究纳入肝衰竭患者50例,其中乙型肝炎肝衰竭15例,药物性肝损伤12例,酒精性肝病13例,自身免疫性肝炎10例;慢性乙型肝炎患者17例和正常人10例。采用PCR法检测PBMCs中HLA-DR mRNA水平,使用流式细胞仪检测CD4+CD25+Treg和Th17细胞百分比。结果乙型肝炎肝衰竭患者HLA-DR mRNA水平为(134.5±15.2),显著高于药物性肝损伤组的(17.9±1.2)、酒精性肝病组的(19.6±2.0)和自身免疫性肝炎组的[(11.2±1.2),P<0.05];不同病因肝衰竭患者Th17和CD4+CD25+Treg细胞百分比[分别为(4.4±0.6)%和(3.9±0.6)%左右]的差异无统计学意义(P>0.05),但与慢性乙型肝炎[分别为(3.7±0.2)%和(6.1±0.4)%和正常人(2.1±0.7)%和(7.0±0.9)%比,均有显著性差异(P<0.05);对不同病因肝衰竭患者进行动态观察发现,19例死亡患者CD4+CD25+Treg细胞百分比呈持续下降,直至死亡,而31例生存患者则逐渐恢复至接近正常水平。结论外周血单个核细胞HLA-DR mRNA水平及Th17和CD4+CD25+Treg细胞百分比的变化与肝衰竭患者的病情密切相关,可作为判断肝衰竭严重程度及预后的指标。

Objective To investigate the changes of HLA-DR mRNA,and Th17 and CD4+CD25+Treg cells in peripheral blood mononuclear cells (PBMCs) in patients with liver failure. Methods HLA-DR mRNA was detected by PCR,and Th17 and CD4+CD25+Treg cells were measured by flow cytometry in 50 patients with liver failure,including 15 arisen from hepatitis B,12 from drug-induced liver injury (DILI),13 from alcoholic liver diseases,and 10 from autoimmune liver diseases,and in 17 patients with chronic hepatitis B and 10 healthy persons. Results The HLA-DR mRNA levels in PBMCs in patients with hepatitis B-induced liver failure was (134.5±15.2),much higher than (17.9±1.2)in DILI- ,(19.6±2.0)in alcoholic and [(11.2±1.2),P<0.05] in autoimmune liver disease-induced liver failure;the percentages of Th17 cells and CD4+CD25+Treg cells [(4.4±0.6)%and(3.9±0.6)% or less,respectively] in patients with different etiologic liver failures were not significantly different (P>0.05),while there were a significant difference as compared to (3.7±0.2)% and (6.1±0.4)% in patients with chronic hepatitis B or(2.1±0.7)% and(7.0±0.9)% in normal control (P<0.05);the percentages of CD4+CD25+Treg cells in 19 died patients decreased gradually,while it increased gradually in 31 survived patients. Conclusion The HLA-DR mRNA levels and CD4+CD25+Treg cells are closely related to the illness severity of patients with liver failure,and they may be used as parameters to estimate the clinical prognosis.
