摘要 目的观察重型再生障碍性贫血(SAA)患者外周血中CD4^+CD25^+T细胞(Treg)百分比及其分泌的细胞因子IL-10、IL-35、TGF-β水平变化,并探讨Treg与患者预后的关系。方法 66例SAA患者,新发30例(新发组),经免疫抑制剂初次治疗后恢复的SAA患者36例(缓解组)。应用流式细胞仪检测两组外周血Treg及其他T细胞亚群;应用ELISA法检测血清IL-10、IL-35、TGF-β。采用Pearson相关分析各T细胞亚群的相关性,应用多元Logistic回归分析评估各T细胞亚群百分比及血清IL-10、IL-35、TGF-β水平与预后的相关性。结果与新发组相比,缓解组Treg细胞、CD8^+T细胞百分比及Treg/CD4^+T高,CD4^+T细胞百分比及CD4^+ T/CD8^+T均低(P均<0.05)。缓解组血清IL-10、IL-35、TGF-β水平高于新发组(P均<0.05)。SAA患者Treg百分比与CD4^+T细胞、CD4^+T/CD8^+ T呈负相关(r分别为-0.689、-0.724,P分别为0.035、0.029),与网织红细胞百分比呈正相关(r=0.667,P=0.038)。多元Logistic回归分析显示,Treg百分比及Treg/CD4^+ T与SAA患者预后有关(P均<0.05)。结论与缓解期SAA患者比较,新发SAA患者外周血Treg百分比及血清IL-10、IL-35、TGF-β水平降低。外周血Treg百分比与SAA患者预后有关。
