异基因造血干细胞移植是一种治疗多种血液学和免疫学疾病的潜在疗法。此外,异基因干细胞移植后的部分或全部供者造血嵌合可能足以保证对来自同一供者的实体器官的免疫耐受,而不需要任何长期的药物免疫抑制。尽管allSCT的潜力很大,但该程序受到两个主要限制的困扰。第一个涉及该程序的毒性,包括预适应方案的毒性、移植物抗宿主病(GVHD)和感染。第二个限制是缺乏组织相容的捐赠者。对于高达40%的患者来说,人类白细胞抗原(HLA)匹配的同胞或无血缘关系的供者无法快速识别。从历史上看,来自部分不相合或单倍体相合的同种异体干细胞移植的亲属移植排斥反应、严重移植物抗宿主病和无复发死亡的发生率高得令人难以接受。最近,我们的团队开发了一种方法,通过移植后在狭窄的窗口内给予高剂量的环磷酰胺,选择性地耗尽体内的同种异体反应性细胞。使用大剂量的移植后环磷酰胺(PT/Cy),在异基因干细胞移植中跨越人类白细胞抗原屏障现在是可行的,几乎所有患者都可以找到供者。本文就大剂量PT/Cy预防移植物排斥反应和移植物抗宿主病(GVHD)的历史、近期临床结果和免疫学机制作一综述。
Allogeneic hematopoietic stem cell transplantation (alloSCT) is a potentially curative therapy for many hematologic and immunologic diseases. Further, partial or full donor hematopoietic chimerism following alloSCT may be sufficient to guarantee immunologic tolerance to solid organs from the same donor, obviating any requirement for prolonged pharmacologic immunosuppression. Despite alloSCT’s potential, the procedure is beset by two major limitations. The first relates to the procedure’s toxicity including conditioning regimen toxicity, graft-versus-host disease (GVHD), and infection. The second limitation is the lack of histocompatible donors. A human leukocyte antigen (HLA)-matched sibling or unrelated donor cannot be identified expeditiously for up to 40% of patients. Historically, alloSCT from partially HLA-mismatched or HLA-haploidentical relatives has been complicated by unacceptably high incidences of graft rejection, severe GVHD, and non-relapse mortality. Recently, our groups have developed a method to selectively deplete alloreactive cells in vivo by administering high doses of cyclophosphamide in a narrow window after transplantation. Using high-dose, post-transplantation cyclophosphamide (PT/Cy), crossing the HLA barrier in alloSCT is now feasible and donors can be found for nearly all patients. This review discusses the history of HLA-haploidentical SCT, recent clinical results and immunologic mechanisms of action of high-dose PT/Cy for prevention of graft rejection and GVHD.
