概括
查固体器官移植接受者的人类疹病毒8 (HHV8) 可能不需要. 一项试点研究发现,从捐赠者传播到接受者的HHV8风险很低,这表明目前的查可能是不合理的.
科学领域:
- 病毒学 病毒学
- 免疫功能低下的患者
- 固体器官移植 实体器官移植
背景情况:
- 人类疹病毒8 (HHV8),也称为卡波西肉瘤相关疹病毒 (KSHV),是一种全球流行病毒.
- HHV8对免疫功能受损的个体构成重大威胁,特别是固体器官移植 (SOT) 接受者,它可以导致危及生命的并发症.
- 在SOT接受者中,来自捐赠者的HHV8感染与高死亡率有关,因此需要早期检测策略.
研究的目的:
- 在一个中心评估HHV8在捐赠者和接受者群体中的血清流行率.
- 在SOT程序中估计HHV8从捐赠者传播到接受者的风险.
- 评估当前对SOT候选人的HHV8查协议的有效性和必要性.
主要方法:
- 进行了一项试点研究,涉及144名捐赠者和145名SOT接受者.
- 间接光检测被用来检测HHV8的Lytic IgG抗体.
- 在捐赠者和接受者队列中确定了血清流行率.
主要成果:
- 在捐赠者中,HHV8血清流行率为2.8%,在接受者中为10.3%.
- 捐赠者-阳性/受体-阴性 (D+R-) 组合的计算风险为2.5%.
- 预计少数D+R-组合会发展出症状的HHV8疾病.
结论:
- 根据试点研究数据,在这个中心可能不需要进行常规的HHV8查.
- 低传播风险表明,目前的查策略可能需要重新考虑.
- 建议进行进一步的多中心研究,以更好地了解SOT患者症状性HHV8感染的风险.

Kidney Transplant I: Introduction
65
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...
