概括
血造细胞移植 (HCT) 后的细胞因子释放综合征 (CRS) 是常见的,特别是在单一的移植中. 温和的CRS可以改善某些HCT接受者的生存率,特别是那些患有髓质恶性瘤的人.
科学领域:
- 血液学 血液学 血液学
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
背景情况:
- 全基性造血细胞移植 (HCT) 是血液恶性瘤的关键治疗方法.
- 移植后循环胺 (PTCy) 越来越多地用于预防移植对宿主疾病.
- 早期移植后细胞因子释放综合征 (CRS) 是一种潜在的并发症,影响HCT结果.
研究的目的:
- 评估552名接受PTCy.治疗的HCT患者中早期CRS的发生率,特征,风险因素和结果.
- 确定CRS对移植与宿主疾病 (GVHD),非复发性死亡率 (NRM) 和整体存活率的影响.
- 分析不同类型的捐赠者和特定患者亚组的CRS影响,包括患有髓质恶性瘤的患者.
主要方法:
- 对552名采用PTCy.治疗的全原性HCT受体进行了回顾性分析.
- 评估CRS发生率,分级 (1-3),以及相关因素.
- 在CRS和非CRS组之间对结果 (GVHD,NRM,生存,复发) 的比较,按捐赠者类型和恶性瘤分层.
主要成果:
- 在182名患者 (33%) 中发生了CRS,其中单一移植 (80%) 与MSD (8%),MUD (23%),MMUD (32%) 的发病率最高.
- 大多数CRS病例是轻微的 (93%的1级,6%的2级);只有一个3级病例.
- 在平分体移植中,CRS与较低的重症慢性GVHD,较低的NRM和改善的生存率相关.
- 在与HLA匹配的患有髓状瘤的接受者中,CRS与复发率降低和生存率改善有关.
结论:
- 在基于 PTCy 的 HCT 后的早期 CRS 是常见的,通常是温和的,但显著影响了生存.
- 在平分异构移植和与HLA匹配的患有骨髓性恶性瘤的患者中,CRS赋予了生存益处.
- 对CRS介导保护机制的进一步研究是有必要的.

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.

Regulation of Hematopoietic Stem Cells
3.1K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
