摘要
目的:探讨慢性淋巴细胞白血病(CLL)患者外周血CD4+CD25+调节性T细胞(Treg细胞)表达及其与预后的相关性。方法:采用流式细胞仪检测50例健康者(对照组)及30例CLL患者(CLL组)治疗前后CD4+CD25+Treg、CD4+CD25+Foxp3+Treg水平。结果:初诊CLL组患者外周血T淋巴细胞数量、CD4+CD25+Treg、CD4+CD25+Foxp3+Treg水平均显著高于对照组,差异有统计学意义(P<0.05)。治疗后,CLL组患者外周血T淋巴细胞数量、CD4+CD25+Foxp3+Treg水平显著降低,与初诊时比较差异有统计学意义(P<0.05),但仍高于对照组(P<0.05)。CLL患者中,Binet临床分期A期患者CD4+CD25+Foxp3+Treg水平显著低于B/C期患者,差异有统计学意义(P<0.05)。Spearman相关分析结果显示,Binet临床分期与CD4+CD25+Foxp3+Treg水平呈正相关(r=0.511,P<0.05)。结论:CD4+CD25+Foxp3+Treg水平可能是评估CLL患者预后的有效指标。
Objectlves:To evaluate the sifnificance of CD4+ CD25+ regulatory T cells for the prognosis of chron- ic lymphocytic leukemia. Method:CD4+ CD25+ Treg and CD4+ CD25+ Foxp3+ Treg level before and after treatment of 50 cases healthy subjects and 30 cases CLL patients were detected by flow cytometry. Resultt The peripheral blood T lymphocytes, CD4+ CD25+ Treg and CD4+ CD25+ Foxp3+ Treg levels of initial diagnostic patients were significantly higher than that of healthy group(P〈0.05). After treatment,the number of peripheral blood T lym phocytes and CD4+ CD25+ Foxp3+ Treg levels of CLL patients were significantly reduced, compared with initial diagnosis(P〈0.05), but still higher than that of healthy group (P〈0.05). In CLL group, the CD4+ CD25+ Foxp3+ Treg of patients with Binet stage A significantly lower than patients with Binet stage B/C(P〈0.05). Spearman correlation analysis showed that Binet stage was positively correlated with CD4+ CD25+ Foxp3+ Treg levels (r= 0. 511, P〈0.05). Conclusion.. CD4+ CD25 + Foxp3+ Treg may be an effective index to evaluate the prognosis of CLL patients.
