摘 要:目的慢性乙型肝炎(乙肝)急性肝衰竭(慢加急性肝衰竭,ACLF)的发病机制尚不清楚,本文主要研究ACLF患者的免疫特点及其与预后的关系。方法选取ACLF患者75例,慢性乙型肝炎(CHB)患者31例,乙型肝炎肝硬化(LC)患者36例,健康志愿者30例,采用流式细胞仪检测外周血CD3+、CD4+、CD8+T细胞、NK细胞、NKT细胞等细胞亚群计数,用SPSS10.0软件对其进行统计学分析。结果ACLF组外周血淋巴细胞总数、CD4+、CD8+T细胞、NKT细胞与健康对照组及慢性乙肝组相比,均具有显著性差异(P<0.001或P<0.01或P<0.05)。ACLF组外周血NK细胞与健康对照组相比,具有显著性差异(P<0.01)。ACLF患者死亡组中淋巴细胞总数、CD4+、CD8+T细胞、NK细胞计数均低于存活组各细胞计数,二者具有显著性差异(P<0.05)。结论ACLF患者外周血免疫活性细胞的减少可能是ACLF病情急剧进展的驱动因素。Objective Since the immunological alterations in acute-on-chronic liver failure ( ACLF ) in chronical hepatitis B virus ( HBV ) -infected patients remain poorly understood, this study attempts to investigate the characterization of immunologically competent cells ( ICCs ) in ACLF and its relationship with the prognosis in those patients. Methods Circulating ICCs, such as CD3^+, CD4^+, CD8^+ T-cells, NKT and NK cells were examined in ACLF patients ( n = 75 ), as well as in patients with chronic hepatitis B ( CHB, n = 31 ), hepatitis B-related liver cirrhosis ( LC, n = 36 ), and normal controls ( NC, n = 30 )with a FACS Calibur Flow Cytometer. SPSSIO.O software was used to make analysis. Results The peripheral blood ( PB ) lymphocytes, CD4^+, CD8^+T-celIs and NKT cells markedly decreased in ACLF patients compared with NC and CHB patients ( P〈 0 .01 or 〈0.01 ,or〈0.05 ). ACLF patients displayed a significant increase in NK cells compared with NC ( P〈 0.01 ). Furthermore, there was a significant increase in the peripheral blood ( PB ) lymphocytes, CD4^+, CD8^+ T cells and NK cells of the non-survivors compared with the survivors in ACLF group ( P〈 0.05 ). Conclusions The decrease of circulating ICCs probably serves as a factor for the progressive development of ACLF.
