摘要:

目的 探讨不明原因反复自然流产(URSA)患者外周血调节性T细胞(Treg)中CD4+CD25+CD127lowT细胞的表达情况及经配偶淋巴细胞免疫治疗后的妊娠结局改变,判断其作为流产指标的可能性。方法 用流式细胞术检测73例URSA患者治疗前、76例正常早孕者(正常早孕组)及69名正常未孕体检者(正常未孕组)外周血中CD4+CD25+CD127lowT细胞百分率,分析经配偶淋巴细胞免疫方法治疗2~3个疗程后的51例URSA患者外周血CD4+CD25+CD127lowT细胞百分率的变化情况。结果 URSA组治疗前外周血CD4+CD25+CD127lowT细胞百分率(2.73%±0.56%)明显低于正常未孕组(2.93%±0.60%)和正常早孕组(4.36%±1.07%)(P<0.05)。51例URSA患者治疗后外周血CD4+CD25+CD127lowT细胞百分率(3.72%±1.15%)明显高于治疗前(P<0.05),其中42例患者治疗后妊娠结局较好,有9例失败。结论 URSA患者外周血CD4+CD25+CD1271owT细胞表达明显降低,其有可能作为判断URSA的指标之一。体外配偶淋巴细胞免疫治疗与妊娠结局改善有关。

Abstract:

Objective To investigate the expression of peripheral blood CD4+CD25+CD1271ow T cells in regulatory T cells (Treg) of patients with unexplained recurrent spontaneous abortion(URSA),to analyze the percentages before and after the treatment of paternal lymphocyte induced immunization,and to evaluate its probability as a diagnosis indicator for abortion. Methods By flow cytometry,the percentages of peripheral blood CD4+CD25+CD1271ow T cells were determined in 73 patients with URSA before the treatment,76 healthy women with early pregnancy and 69 healthy women without pregnancy. A total of 51 patients with URSA underwent the treatment of paternal lymphocyte induced immunization for 2-3 treatment courses. Their percentages were determined as well. Results Before the treatment,the percentage of CD4+CD25+CD1271ow T cells in URSA group (2.73%±0.56%) was lower than those in healthy pregnancy and non-pregnancy groups(4.36%±1.07% and 2.93%±0.60%)(P<0.05). After the treatment,the percentage(3.72%±1.15%)was higher than that before the treatment(P<0.05). The pregnancy outcome of 42 patients after the treatment was good,while the treatment for the other 9 patients failed. Conclusions The percentage of peripheral blood CD4+CD25+CD1271ow T cells in URSA patients is lower than those in healthy pregnant and non-pregnant women,which can be as a diagnosis indicator for URSA,and it can be improved by the treatment of paternal lymphocyte induced immunization.
