概括
在脏再移植患者中识别重复质细胞不匹配 (DREMM) 和预先形成的捐赠者特异性抗体 (DSA) 可以预测抗体介导排斥和移植损失. 需要进一步的研究来确认它们的临床实用性.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 免疫学 免疫学 免疫学
- 移植科学 移植科学
背景情况:
- 脏再移植比第一次移植带来更高的风险,通常是由于HLA敏感化.
- 反复发生的质细胞不匹配在再移植结果中的作用仍未得到充分研究.
研究的目的:
- 评估抗体中介排斥 (ABMR) 和与预先形成的供体特异性抗体 (DSA) 相关的移植损失的风险,以向脏再移植中的重复质不匹配 (DREMM).
- 研究DREMM对敏感患者临床结果的影响.
主要方法:
- 对45名脏再移植患者的回顾性分析,对第二个捐赠者进行了预先形成的DSA.
- 使用HLAMatchmaker®在片水平上分析了HLA不兼容性和DSA特异性.
- 评估结果包括ABMR和死亡审查的移植存活率.
主要成果:
- 反复的不匹配在片水平 (87%) 比抗原水平 (22%) 更常见.
- 60%的患者患有DREMM,这与较高的ABMR率 (70%与28%) 和较低的移植存活率 (P=0.01) 相关.
- 多变量分析没有证实DREMM作为ABMR风险的独立预测因素.
结论:
- 在脏再移植中识别DREMM可能会提供对拒绝风险的临床见解.
- 需要进行更大规模的研究,以准确确定DREMM对ABMR和移植存活的预测价值.

Tissue Transplantation
338
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.
