皮下免疫疗法(SCIT)为几种常见的过敏性疾病提供了有效的疾病治疗疗法。在治疗过敏性鼻炎、过敏性结膜炎、过敏性哮喘和昆虫过敏方面,SCIT的安全性和有效性已经得到证实。对于有气源性过敏原过敏的特应性皮炎患者,也可以考虑使用SCIT。

皮下免疫疗法(SCIT)是治疗过敏性鼻结膜炎的一种有效方法。然而,可能会发生不良事件,包括危及生命的全身性反应。近期,有研究人员确定了皮下免疫疗法的全身反应的风险因素,并利用质量改进(QI)框架提供基于实践的解决方案

研究人员在加拿大一家医院过敏诊所开展了一项QI倡议,为期12个月。在12个月内共进行了4242次SCIT的注射。其中,10次注射导致了需要使用肾上腺素的全身反应(即424次注射中有1次发生不良事件,占比0.24%)。8名患者中至少有1个记录在案的全身性反应的风险因素,6名患存在多个风险因素。主要风险因素包括过敏性鼻炎的季节性加重、未受控制的哮喘和给药途径的错误。另外,所有的反应都发生在最高的过敏原提取物浓度下。

对SCIT有全身性反应的相关风险因素

综上所述,这项质量改进措施强调了改善病人和医护人员教育和用药前筛查的必要性。研究提出了SCIT管理的几个注意事项:为患者提供关于安全性的书面信息;在注射前对患者进行筛查,包括审查治疗计划的依从性和哮喘控制情况;调整剂量以减缓最高浓度免疫疗法提取物的积累,特别是对高风险患者;对具有多种风险因素的患者采用额外的安全措施。
