概括
血池的病原体减少治疗 (PRT) 维持了XVIII因子水平,但减少了纤维素原体. 接受PRT治疗的血显示sCD40L增加,血液组分布影响因子VIII和IL-18度.
科学领域:
- 输血医学 输血医学
- 血液产品安全 血液产品安全
- 免疫学 免疫学 免疫学
背景情况:
- 法国的一项标准化病原体减少治疗 (PRT) 程序将5个单位的全血血集成为两个体积.
- 这一过程产生了6个新鲜冷等离子体,经过5个原生等离子体的Amotosalen和紫外线A (FFP-A/UVA) 处理.
- 益处包括治疗时间缩短,成本降低,产品标准化,通过稀释过敏原和炎症调解剂减少不良事件.
研究的目的:
- 为了比较A/UVAPRT或没有A/UVAPRT的ABO同组或通用血池中的VIII因子,纤维素和可溶性炎症因子度.
- 评估小型池 (5个单位) 和大型池 (10个单位) 中等离子体单位的配置和标准化.
主要方法:
- 对可溶性炎症生物标志物 (如sCD40L,IL-18) 和循环免疫复合物的分析.
- 第八因子和纤维素原水平的量化.
- 未经治疗和接受PRT治疗的非血单元的比较.
主要成果:
- 第八因子水平保持稳定;纤维素素水平显著下降,但在PRT血中保持在2g/L以上.
- 在个体接受PRT治疗的血中,sCD40L显著增加,而IL-18水平保持不变.
- 迷你和巨型池中的血型分布影响了因子VIII和IL-18度,但不影响纤维素素或sCD40L. 在聚合血中观察到较少的个体间变异.
结论:
- 建议采用迷你池方法来生产通用等离子体或更大的体积混合物.
- 血型分布至关重要,因为sCD40L和IL-18会影响免疫反应,并可能减少输血后的过敏反应.
- 需要进一步的临床研究,包括输血后的随访,以确认这些发现的临床相关性.

The ABO Blood Group
2.3K
The ABO blood group system is a critical element of transfusion medicine, essential for determining blood compatibility in transfusions and organ transplants. It is based on specific antigens, or agglutinogens, present on the surface of red blood cells (RBCs) and corresponding antibodies, or agglutinins, in the blood plasma.
Antigens in the ABO Blood Group System
Antigens are substances that can trigger an immune response, leading to the production of antibodies. In the ABO blood group system,...
