Campath-1H诱导在小肠移植免疫抑制中的作用

Effect of Campath-lH induction on immunosuppression in small intestine transplantation

目的探讨Campath-1H诱导在小肠移植免疫抑制中的作用。方法回顾性总结1例小肠移植患者的临床资料。结果术中采用Campath-1H静脉注射诱导，术后予以FK506加MMF加激素三联免疫抑制方案。Campath-1H诱导后淋巴细胞及白细胞数目明显减少．经提升白细胞治疗和调整免疫抑制剂用量后逐渐恢复正常。术后早期，患者未发生急性排斥反应及移植物抗宿主病（GVHD），无严重感染症状，患者顺利渡过围手术期，康复出院。结论Campath-1H术中诱导．术后小剂量FK506加MMF加激素三联免疫抑制方案．可有效控制小肠移植术后早期排斥反应和GVHD的发生。

Objective To investigate the effect of Campath-1H induction on immunosuppression in small intestine transplantation. Methods Clinical data of a patient who underwent small intestine transplantation were retrospectively summarized. Results Intraoperative Campath-1H induction by intravenous injection was administered. Triple immunosuppression （FK506, MMF and methylprednisolone） was used postoperatively. The lymphocyte and leukocyte decreased significantly following Campath-1H induction, and returned to normal after adjusting the dose of immunosuppressant and use of colony stimulating factor. There were no acute rejection, graft versus host disease, or severe infection during the immediate postoperative period. The patient recovered and discharged. Conclusion Intraoperative Campath-1H induction and postoperative triple immunosuppression using FK506, MMF, and methylprednisolone may prevent rejection and graft versus host disease in the early stage after small intestine transplantation.
