概括
移植后淋巴增殖障碍 (PTLD) 是心脏移植接受者的重大风险,通常与爱斯坦-巴尔病毒 (EBV) 和免疫抑制有关. 早期诊断和减少免疫抑制疗法是有利结果的关键.
科学领域:
- 移植免疫学和瘤学.
- 了解移植后并发症和淋巴增殖性疾病.
背景情况:
- 恶性病是心脏移植后的一种严重并发症.
- 移植后淋巴增殖性疾病 (PTLD) 是移植受体中常见的恶性瘤,特别是在儿童中.
- 移植器官的PTLD发病率因移植器官而异,由于免疫抑制强度,胸部器官的发病率更高 (高达10%).
研究的目的:
- 突出心脏移植患者中PTLD的发病率和风险因素.
- 讨论PTLD的诊断和治疗策略.
- 在心脏移植接受者中呈现PTLD病例.
主要方法:
- 关于PTLD发病率,病变发生和治疗的文献综述.
- 一个心脏移植接受者的病例报告,他患上了PTLD.
- 讨论包括组织学检查在内的诊断方法.
主要成果:
- 胸部器官移植的PTLD发病率高于胸部器官移植 (高达10%),而不是脏移植 (1-2%).
- EBV感染和长期的免疫抑制疗法是PTLD发展的关键因素.
- 早期发病的PTLD通常是与EBV相关的B细胞淋巴瘤,对降低免疫抑制和rituximab反应良好.
结论:
- 及时诊断和干预,包括减少免疫抑制疗法 (IST),对于PTLD管理至关重要.
- 虽然早期的PTLD有更好的预后,但高级淋巴瘤的五年生存率为30%,EBV阴性病例的情况更糟.
- 收养T细胞转移显示出对抗性PTLD病例的前景.

Kidney Transplant I: Introduction
29
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...

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.

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...
