概括
找到匹配的无血缘关系捐赠者的机会很小的患者仍然可以使用替代捐赠者策略实现血造干细胞移植 (HCT). 供体可用性很少会延迟HCT,疾病或患者健康是延迟的主要原因.
科学领域:
- 造血干细胞移植 (HCT) 的方法
- 免疫遗传学 免疫遗传学
- 移植免疫学 移植免疫学
背景情况:
- 供体选择对于HCT成功至关重要.
- 接受者搜索预后 (SP) 根据找到一个8/8匹配的非相关捐赠者 (MUD) 的可能性对患者进行分层.
- 替代捐赠者 (Alt-D) 战略越来越重要.
研究的目的:
- 在BMT CTN 1702试验的二次分析中,分析基于受体搜索预后 (SP) 的供体搜索和选择策略.
- 评估在MUD匹配可能性较低的患者中使用替代捐赠者的有效性.
主要方法:
- 对1751名患者的分析分为三个SP群:非常可能,不太可能和非常不可能.
- 评估基线供体偏好,优先级排名的变化,以及为什么没有选择类型供体的原因.
- 评估HCT率,时间表,以及SP组间延迟原因.
主要成果:
- 较少/非常不太可能的SP组中的患者使用了更多的Alt-D类型,包括平分异性和不匹配的无血缘捐赠者 (MMUD).
- 不选择的原因包括HLA不匹配和捐赠者特异性抗体,根据SP不同.
- 65%的患者达到HCT; 94%的很可能SP使用MUD,而91%的很不可能SP使用Alt-D.
- HCT延迟发生在29%的患者中,主要是由于疾病或患者的健康状况,而不是因为有供体可用性.
结论:
- 一个早期的以供体为中心的替代策略允许MUD匹配可能性较低的患者以可比的速度和类似的努力达到HCT.
- 往往无法达到HCT的目标时间,延迟主要是由疾病或患者健康状况引起的.
- 在所有搜索预后组中,供体可用性不是HCT延迟的常见原因.

Kidney Transplant I: Introduction
349
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Bone Marrow Sampling and Transplants
910
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.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Tissue Transplantation
928
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.

Kidney Transplant II: Surgical Procedure
325
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...
