概括
血造细胞移植 (HCT) 后常见的流体过载 (FO) 与移植后的环胺 (PTCy). 严重的FO显著增加非复发性死亡率 (NRM) 和降低生存率,突出需要仔细监测.
科学领域:
- 血液学 血液学 血液学
- 移植免疫学 移植免疫学
- 在瘤学瘤学.
背景情况:
- 出血性囊炎 (HC) 是血液细胞移植 (HCT) 后经常出现的早期并发症,该并发症利用移植后的环胺 (PTCy).
- 虽然过水是用来减轻HC的,但它可以导致流体过载 (FO),这种情况与HCT后的非复发性死亡率 (NRM) 的增加有关.
研究的目的:
- 在HCT后的第3天和第8天之间建立FO的分级系统.
- 评估FO对NRM和总生存时间 (OS) 的影响,在接受基于PTCy的移植与宿主疾病 (GvHD) 预防的患者中.
主要方法:
- FO的分级是基于体重增加,利尿剂的使用和器官功能障碍.
- 分析包括了275名在2009年至2018年期间接受PTCy和HCT的患者.
- 根据临床参数,FO从0到4进行分级.
主要成果:
- 98%的患者出现了早期FO (3-8天),8%的患者出现了严重的 (3-4级) FO.
- 3-4级FO与100天NRM (59.1%) 与0-1级 (1.7%) 和2级 (8.8%) 的FO相比显著更高.
- 两年生存期和无病生存期 (DFS) 在患有3-4级FO的患者相比患有0-1级或2级FO的患者要低得多.
- 体重增加5%与NRM增加相关 (HR=1.91).
结论:
- 液体过载 (FO) 在接受PTCy诱导的HC过水的患者中几乎普遍存在.
- 严重的FO (3-4级) 很少发生,但预后不好.
- 监测体重增加可以作为FO和相关风险的早期,可能可修改的指标.

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.

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...

Tissue Transplantation
322
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.
