ARCH PATHOL LAB MED:输血传播的巴贝西虫病

2019-02-05 MedSci MedSci原创

巴贝虫病最常由巴贝斯虫(Babesia microti)引起,并通过受感染的Ixodes spp tick 的叮咬传播。然而,巴贝虫也可通过输血传播。在美国,第一例输血传播的巴贝西病发生在1979年,近年来,发病率迅速增加。由于大多数受感染的献血者没有任何症状,因此对血液供应构成重大风险。目前正在进行巴贝虫病史的捐献者推迟但无效。2018年3月,美国食品和药物管理局(FDA)批准了DNA PCR和

巴贝虫病最常由巴贝斯虫(Babesia microti)引起,并通过受感染Ixodes spp tick 的叮咬传播。然而,巴贝虫也可通过输血传播。在美国,第一例输血传播的巴贝西病发生在1979年,近年来,发病率迅速增加。由于大多数受感染的献血者没有任何症状,因此对血液供应构成重大风险。目前正在进行巴贝虫病史的捐献者推迟但无效。20183月,美国食品和药物管理局(FDA)批准了DNA PCR和抗体检测,这些检测在关键试验中用于筛选献血者的微生物; 其他检测方法仍在研究新药方案中进行评估。献血筛查对于降低输血传播的巴贝西虫病风险至关重要,这就是为什么自2010年左右开始在最高风险地区收集的血液中心进行测试的原因。更高灵敏度的研究性NAT检测正在等待FDA审查。此外,在20187月,FDA发布了降低输血传播的巴贝西虫病风险的指南草案。在对所有当前和潜在战略的敏感性和特殊性进行适当评估之前,可能会推迟发布最终指南。
