概括
捐赠者衍生的无细胞DNA (dd-cfDNA) 提供了一种非侵入性方法来监测固体器官移植排斥. 这种方法可以安全地减少侵入性活检的需要,使得早期检测移植损伤和个性化免疫抑制.
科学领域:
- 移植免疫学 移植免疫学
- 分子诊断学 分子诊断学
- 植入物监视监视 植入物监视
背景情况:
- 固体器官移植的排斥是移植失败的主要原因,需要可靠的监测方法.
- 目前的黄金标准,侵入性活检,带有风险,并发症和观察者之间的变化.
- 无侵袭性生物标志物对于全移植损伤对于改善患者的治疗结果至关重要.
研究的目的:
- 评估来自供体的无细胞DNA (dd-cfDNA) 测试在监测实体器官移植受体中的有用性.
- 介绍匈牙利初步使用dd-cfDNA进行心脏全移植排斥监测的经验.
- 评估dd-cfDNA在指导免疫抑制疗法和减少侵入性手术方面的潜力.
主要方法:
- 从实体器官移植接受者的血样本中分析dd-cfDNA水平.
- 使用dd-cfDNA作为移植损伤的生物标志物,对轻度和重度损伤有明确的值.
- 在心脏移植患者中,dd-cfDNA水平与内心肌瘤活检 (EMB) 的临床指示的相关性.
主要成果:
- 在心脏移植患者中,80%的dd-cfDNA测量低于损伤值.
- 较高的dd-cfDNA水平促使20个因果内心肌瘤活检,导致诊断了6次排斥发作.
- dd-cfDNA测试使得在16个月内安全避免了88%的例行监测活检.
结论:
- dd-cfDNA测试是监测固体器官移植排斥的有价值的非侵入性工具,特别是在心脏全移植中.
- 这种方法有助于早期检测移植损伤,允许个性化免疫抑制定位.
- 减少常规活检的需要可以提高患者的安全性,并可能防止不可逆转的移植功能障碍.

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.

Tissue Transplantation
350
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.
