概括
贝拉塔塞普特有效地降低了肺移植接受者的捐赠者特异性抗体 (DSA). 这种治疗还防止了新的DSA发展和抗体介导排斥 (AMR).
科学领域:
- 免疫学 免疫学 免疫学
- 移植医学 移植医学
- 药理学 药理学是指药理学的学科.
背景情况:
- 众所周知,贝拉塔塞普通过消除捐赠者特异性抗体 (DSA) 来改善移植的结果.
- 它对接受肺移植 (LTx) 患者的新型DSA的影响需要进一步调查.
- 了解贝拉塔塞普特在LTx中的作用对于管理移植后免疫反应至关重要.
研究的目的:
- 评估贝拉塔塞普特对肺移植 (LTx) 患者新生捐赠者特异性抗体 (DSA) 的作用.
- 为了评估抗体中介排斥 (AMR) 在接受贝拉塔塞普特治疗的LTx患者中的发生率.
- 分析Belatacept开始后DSA平均光强度 (MFI) 的变化.
主要方法:
- 在2018年1月至2023年8月期间,对LTx患者进行了多机构的回顾性审查,这些患者新发病了DSA并接受了Belatacept.
- 使用线性混合效应模型分析DSA MFI在Belatacept前后的变化.
- 对二次结果的评估,包括AMR的发生.
主要成果:
- 在44名患有DSA的LTx患者中,贝拉塔塞普导致57%的DSA解决,16%的减少.
- 在贝拉塔塞普治疗期间没有新的de novo DSA发展,治疗后MFI显著下降 (p < 0.001).
- 在接受贝拉塔塞普特治疗期间,没有患者出现AMR,而在开始治疗之前的AMR为57%.
结论:
- 贝拉塔塞普的使用与肺移植接受者的DSA显著减少有关.
- 这项研究代表了研究贝拉塔塞普特在LTx患有DSA的患者中疗效的最大队列.
- 贝拉塔cept在控制免疫反应和预防肺移植后AMR方面表现出潜力.

Kidney Transplant I: Introduction
307
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

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.
