- 移植手术 移植手术
- 免疫学 免疫学 免疫学
背景情况:
- 由于间歇性肺炎导致肺功能迅速下降的患者需要紧急的肺移植.
- 一位潜在的活体捐赠者检测出B型肝炎表面抗原 (HBsAg) 呈阳性,造成B型肝炎病毒 (HBV) 传播的高风险.
研究的目的:
- 评估活体捐赠者叶叶肺移植 (LDLLT) 的安全性和有效性,对接受者具有乙型肝炎表面抗原阳性捐赠者.
- 评估在接受者和捐赠者接受LDLLT后采取预防措施后,HBV传播和重新激活的风险.
主要方法:
- 接受者接受了人类抗HBV表面免疫球蛋白和恩特卡维尔的预防性治疗.

- 在移植后六个多月内,在接受者和捐赠者中持续监测HBV活性.
主要成果:
- 接受者在整个术后期间保持HBsAg和HBsAb阴性,表明没有HBV感染.
- 在接受者身上没有观察到HBV重新激活的迹象,即使在接受急性细胞排斥的皮质类固醇脉冲疗法之后.
- 无论是接受者还是捐赠者,在LDLLT后六个多月内都没有显示出HBV再激活的证据.
结论:
- 在使用适当的预防策略时,活体捐赠者叶叶肺移植在HBsAg阳性捐赠者接受者中是可行的和安全的.
- 使用抗HBV免疫球蛋白和恩特卡维尔的预防有效地防止HBV的传播和在接受者和捐赠者中重新激活.
- 精心选择供体,风险评估和术后管理对于在高风险的HBV场景中成功移植至关重要.

Kidney Transplant I: Introduction
14
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...
