概括
量子-CMV (QTF-CMV) 试验可以指导高风险移植受体中细胞巨乳病毒 (CMV) 预防的持续时间. 这种细胞介导免疫 (CMI) 测试对接受者血清阳性患者有益,但对捐赠者血清阳性/接受者血清阴性患者不利.
科学领域:
- 移植免疫学 移植免疫学
- 病毒学 病毒学
- 临床医学 临床医学
背景情况:
- 关于使用细胞介导免疫 (CMI) 来指导抗病毒预防的有限的干预研究存在.
- 细胞巨乳病毒 (CMV) 仍然是器官移植受体的一个重大问题.
研究的目的:
- 评估量子素-CMV (QTF-CMV) 试验在指导CMV预防持续时间方面的有用性.
- 评估CMI导向预防对高风险移植受体中CMV病毒病的影响.
主要方法:
- 一项单臂多中心前性研究涉及高风险的脏,胰腺,肝脏和心脏移植接受者.
- QTF-CMV测定用于检测移植后3,4,5和6个月的CMI.
- 预防在阳性CMI时被停止,在阴性CMI时继续,主要终点为CMV病毒血清≥1000 IU/mL.
主要成果:
- 在108名患者中,有89人完成了这项研究. 在供体血清阳性/受体血清阴性 (D+/R-) 患者中,只有2.6%的患者呈阳性CMI.
- 在接受者血清阳性 (R+/ATG) 患者中,66%的CMI为阳性,允许早期停止预防治疗.
- 在R+/ATG患者中,早期停止治疗与较低的CMV病毒性病率 (12.1%与35.3%) 有关.
结论:
- 以QTF-CMV为导向的预防对接受者血清阳性 (R+/ATG) 患者有效,使得量身定制的预防持续时间.
- 这种以CMI为指导的策略对捐赠者血清阳性/接受者血清阴性 (D+/R-) 患者没有好处.

Tissue Transplantation
350
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
