摘要:

背景:骨髓间充质干细胞在体内外均具有免疫调节能力,但其对肾移植受者体内CD4+ T细胞免疫状态的影响目前仍不清楚。
目的:探讨ImmuKnow检测技术对肾移植受者CD4+ T细胞免疫状态的监测作用及骨髓间充质干细胞诱导治疗对受者细胞免疫功能的影响。
方法:选择2011年1月至2013年6月于解放军南京军区福州总医院行同种异体肾移植并接受自体骨髓间充质干细胞诱导治疗的受者24例,以各项移植前指标匹配、接受巴利昔单抗诱导治疗的肾移植受者48例作为对照。两组受者分别于移植前、移植后第14,30,60,90,180天,以及在发生急性排斥或感染时抽取静脉血,以ImmuKnow法检测CD4+ T细胞三磷酸腺苷水平。
结果与结论:移植后6个月内,骨髓间充质干细胞组急性排斥和移植后总感染发生率均低于巴利昔单抗组,但差异无显著性意义。两组受者移植后外周血CD4+ T细胞三磷酸腺苷水平均明显低于移植前(P < 0.05),但两组之间比较差异无显著性意义。骨髓间充质干细胞组12例、巴利昔单抗组26例发生了移植后感染,这些受者发生感染时CD4+ T细胞三磷酸腺苷水平均明显低于病情稳定时(P < 0.01)。结果表明骨髓间充质干细胞诱导治疗可有效降低肾移植受者的细胞免疫功能,而ImmuKnow法检测外周血CD4+ T细胞三磷酸腺苷含量可有效反映受者的细胞免疫状态。

Abstract:

BACKGROUND: Bone mesenchymal stem cells have immunological regulation function both in vitro and in vivo, while the effect of bone marrow mesenchymal stem cells on CD4+ T cell immune function in patients receiving kidney transplantation remains unclear.
OBJECTIVE: To explore the monitoring significance of CD4+ T-cell immune function by ImmuKnow assay and to determine the effect of induction therapy with bone marrow mesenchymal stem cells on cell immune function in patients receiving kidney transplantation.
METHODS: From January 2011 to June 2013, 24 patients receiving allograft renal transplantation with autologous bone marrow mesenchymal stem cells were included and another 48 patients receiving allograft renal transplantation and Simulect induction therapy with various matched preoperative characters served as controls. In both groups, adenosine triphosphate levels in CD4+ T cells in the peripheral blood were determined by the ImmuKnow assay preoperatively and at 14, 30, 60, 90, 180 days postoperatively, as well as during acute rejection and infection episodes.
RESULTS AND CONCLUSION: During the 180 days postoperatively, fewer patients in the bone marrow mesenchymal stem cell group had acute rejection and injection than the Simulect group, but no significant differences were observed. Postoperative adenosine triphosphate levels in CD4+ T cells were significantly lower than those determined preoperatively in both groups (P < 0.05), while no significant differences were observed between the two groups. A total of 12 patients in the bone marrow mesenchymal stem cell group and 26 patients in the Simulect group had infection episodes, and the adenosine triphosphate levels in CD4+ T cells during the infection episodes were lower than clinical stable patients in both groups (P < 0.01). For patients receiving renal transplantation, induction therapy with bone marrow mesenchymal stem cells can effectively decrease the cell immune function, which can be reflected by the adenosine triphosphate levels in CD4+ T cells in the peripheral blood determined by the ImmuKnow assay.
