Abstract

Passive immunization with polyclonal hyper immunoglobulin (HIG) therapy represents a proven strategy by transferring immunoglobulins to patients to confer immediate protection against a range of pathogens including infectious agents and toxins. Distinct from active immunization, the protection is passive and the immunoglobulins will clear from the system; therefore, administration of an effective dose must be maintained for prophylaxis or treatment until a natural adaptive immune response is mounted or the pathogen/agent is cleared. The current review provides an overview of this technology, key considerations to address different pathogens, and suggested improvements. The review will reflect on key learnings from development of HIGs in the response to public health threats due to Zika, influenza, and severe acute respiratory syndrome coronavirus 2.

摘要

被动免疫接种多克隆高免疫球蛋白(HIG)治疗代表了一种通过将免疫球蛋白转移给患者来提供针对多种病原体(包括传染性病原体和毒素)的即时保护的成熟策略。与主动免疫不同,这种保护是被动的,免疫球蛋白将从系统中清除;因此,必须维持有效剂量的给药以进行预防或治疗,直到自然适应性免疫反应建立或病原体/抗原被清除。本综述概述了该技术,解决不同病原体的关键注意事项以及提出的改进建议。本综述将从应对寨卡病毒、流感和严重急性呼吸综合征冠状病毒 2 等公共卫生威胁时开发 HIG 的经验中吸取关键教训。
