Mult Scler:复发缓解型多发性硬化症患者应用单一SARS-COV-2疫苗后血清转换率降低

2021-10-08 从医路漫漫 MedSci原创

服用免疫抑制药物的病人优先接种SARS-COV-2疫苗。几种SARS-COV-2疫苗已在具有免疫能力的个人身上证明有效,强调体液免疫结果。但是,单剂疫苗对B细胞耗尽的患者的疗效尚不清楚。

背景:服用免疫抑制药物的病人优先接种SARS-COV-2疫苗。几种SARS-COV-2疫苗已在具有免疫能力的个人身上证明有效,强调体液免疫结果。但是,单剂疫苗对B细胞耗尽的患者的疗效尚不清楚。为了确定它们是否产生体液免疫反应,我们在疫苗接种后检测了SARS-COV-2IgG血清转换率。

目的:我们的目标是量化奥立珠单抗接受者的疫苗免疫原性。

方法:我们使用高度敏感的Luminex检测奥克雷珠单抗受体接种后的SARS-COV-2免疫球蛋白G (IgG)。

结果:44.1%的患者在一次疫苗接种后21+天检测出SARS-COV-2-IgG,无论疫苗类型(AZD1222 vs BNT162b2,优势比(OR) = 0.62, 95%可信区间(CI) = 0.157-2.32, p = 0.72)。B细胞计数可显著预测血清转化(β1 = 12.38, 95% CI = 4.59 - 20.16, p = 0.0029),但未检测到B细胞并不能排除血清转化。第二种疫苗的血清转换率为53%,这些患者对第一剂疫苗没有反应。

图 (A)在接种前已知为阴性的患者(N=34),在接种1剂疫苗后可检测到SARS-COV-2IgG(通过靶表位)。(B)-(E)单因素分析CD19计数、IgM、IgG和第一次接种疫苗至注射奥立珠单抗的间隔时间(第一次接种前后血型相匹配的亚组,N=34)。(F)疫苗类型的效果(第一针后)。(G)所有患者在接种1剂疫苗后均可检测到SARS-COV-2 IgG(不论接种前结果如何)。(H)对第一剂疫苗没有反应的患者在第二剂疫苗接种后的血清转换(N=15)。S:刺激蛋白;R:受体结合域;N:核衣壳蛋白;AZD1222:牛津-阿斯利康疫苗;BNT162b2:辉瑞-生物科技疫苗。

结论:我们的目标是确定在接种SARSCOV-2疫苗后,接受B细胞耗竭药物ocrelizumab治疗的患者是否产生了可检测到的体液免疫反应。我们观察到该人群在接种一剂疫苗后早期体液免疫反应减弱。CD20耗竭患者接种一剂新冠肺炎疫苗后的体液反应低于预期。这项研究增加了CD20耗竭患者早期体液免疫减弱的越来越多的证据。细胞免疫和加强免疫的贡献仍有待充分评估。
