血清可溶性白介素2受体水平与急性移植物抗宿主病关系的研究
首发时间:2014-02-18
摘要:目的:研究患者血清可溶性白细胞介素2受体(sIL-2R)水平与急性移植物抗宿主病(aGVHD)的发生、严重程度及疗效间的关系。方法:ELISA方法检测患者血清中sIL-2R的水平;根据患者应用CD25单克隆抗体前后GvHD积分的改善情况判定疗效。结果:1、患者血清sIL-2R水平在aGVHD时明显升高,aGVHD好转后则降低,且随aGVHD的加重而升高,III -IV aGVHD患者与另外二组相比时有明显统计学差异。2、出现aGVHD患者,在应用CD25单克隆抗体治疗后,有效患者的血清sIL-2R水平明显下降,部分无效患者则在一过性的降低后出现升高。结论:血清sIL-2R水平与aGvHD的严重程度有关。连续检测血清sIL-2R水平对于重度aGvHD的诊断和CD25单克隆抗体疗效的评价有一定帮助作用。

Study of relationship between serum levels of interleukin 2 soluble receptor and acute graft versus host disease
Abstract:Objective: To investigate whether the serum levels of sIL-2R were associated with the severity and the therapeutic efficacy of acute graft-versus-host disease. Methods: The therapeutic efficacy of GVHD was determined by the improvement of the symptoms and lab test. The serum levels of sIL-2R were tested with ELISA kit. Results: Serum levels of sIL-2R increased after transplantation and achieved plateau during aGVHD and decreased after regression of aGVHD. Serum levels of sIL-2R were also related to the severity of aGVHD and decreased after complete response following treatment with CD25 monoclonal antibody. On the contrary, in those that didn't response to the treatment, the levels of sIL-2R increased after transient descent. Conclusions: sIL-2R level in serum is related to the severity of aGvHD. CD25 monoclonal antibody can significantly decrease the serum levels of sIL-2R in patients who achieved complete response. These results demonstrate that continuous detection of serum levels of sIL-2R may be helpful to the diagnosis of aGVHD and the evaluation of the therapeutic efficacy of the agent.
