摘要:

目的 探讨急性髓性白血病(AML)患者淋巴细胞中CD39+CD4+CD25+T细胞比例与预后的相关性。方法 选取AML患者157例(AML组),并将其按AML 5种亚型分为AML-M1、AML-M2、AML-M3、AML-M4和AML-M5 5个亚组,以41名体检健康者作为正常对照组。采用流式细胞术检测所有对象外周血CD39+CD4+CD25+T细胞和+CD4+CD25+T细胞占淋巴细胞的比例。分别根据CD39+CD4+CD25+T细胞或CD4+CD25+T细胞占淋巴细胞的比例将AML患者分为低、中、高水平组。结果 AML组及各亚组CD39+CD4+CD25+T细胞比例均明显高于正常对照组(P<0.05)。AML组与正常对照组之间CD4+CD25+T细胞比例差异无统计学意义(P>0.05),但AML-M1组明显低于正常对照组(P<0.05)、AML-M2组明显高于正常对照组(P<0.05)。CD39+CD4+CD25+T细胞低水平组、中水平组和高水平组髓外浸润比例及骨髓原始细胞CD34、CD7阳性率依次升高,各组间差异有统计学意义(P<0.05)。CD4+CD25+T细胞低水平组、中水平组和高水平组之间髓外浸润及CD34、CD7阳性率差异均无统计学意义(P>0.05)。与CD39+CD4+CD25+T细胞低水平组比较,中水平组和高水平组的下次治疗时间(TTT)较短(P<0.05);而CD4+CD25+T细胞低水平组、中水平组和高水平组之间TTT差异无统计学意义(P>0.05)。结论 CD39+CD4+CD25+T细胞比例升高与AML预后较差有关。CD39或可作为AML疾病发展的标志物。

Abstract:

Objective To investigate the correlation between the percentage of CD39+CD4+CD25+ T cells in lymphocytes and prognosis in patients with acute myeloid leukemia(AML).Methods A total of 157 patients with AML(AML group) were enrolled and classified into 5 subtype groups (AML-M1,AML-M2,AML-M3,AML-M4 and AML-M5),and 41 healthy subjects were enrolled as healthy control group. By flow cytometry,the percentages of CD39+CD4+CD25+ T cells and CD4+CD25+ T cells in lymphocytes were determined. AML group was sub-classified into low-,middle- and high-level groups according to the percentage of CD39+CD4+CD25+ T cells or CD4+CD25+ T cells in lymphocytes.Results Compared to healthy control group,the percentages of CD39+CD4+CD25+ T cells in lymphocytes were higher in AML group and its 5 subtype groups(P<0.05). There was no statistical significance for the percentages of CD4+CD25+ T cells between AML and healthy control groups(P>0.05),but the percentage of AML-M1 subtype group was lower than that in healthy control group(P<0.05),and the percentage of AML-M2 subtype group was higher than that in healthy control group(P<0.05).The proportion of extramedullary infiltration and the positive rates of CD34 and CD7 of blast cells in low-,middle- and high-level groups according to the percentages of CD39+CD4+CD25+ T cells in lymphocytes were gradually increased(P<0.05),but there was no statistical significance among low-,middle- and high-level groups according to the percentages of CD4+CD25+ T cells in lymphocytes(P>0.05). Patients with high- and middle-level CD39+CD4+CD25+ T cell percentages had a shorter time to next treatment (TTT) compared with patients with low-level CD39+CD4+CD25+ T cell percentage(P<0.05). However,patients with low-,middle- and high-level CD4+CD25+ T cell percentages had no statistical significance for TTT(P>0.05).Conclusions The increasing percentage of CD39+CD4+CD25+ T cells in lymphocytes is correlated with poor prognosis,and CD39 may be a marker for the disease development of AML.
