AJCD:特应性皮炎患者接种BNT162b2基因疫苗的决定因素和效果

2022-03-28 医路坦克 MedSci原创

本文评估了BNT162b2信使RNA疫苗在AD患者中的流行率,并评估其在预防严重急性呼吸综合征冠状病毒2(SARS-CoV-2)感染、新冠肺炎相关住院和死亡率方面的有效性。

     虽然目前由严重急性呼吸综合征冠状病毒2型(SARS-CoV-2)引起的新冠肺炎大流行仍在全球造成严重破坏,但随着针对SARS-CoV-2的信使RNA疫苗的批准,新的希望已经出现。两种授权的新冠肺炎基因疫苗,BNT162b2和mRNA1273,是以脂质纳米粒包装的表达SARS-CoV-2灌注尖峰糖蛋白的化学修饰疫苗。超过90%的个体获得了令人满意的体液应答,在具有免疫能力的受试者中,mRNA COVID19疫苗显示出良好的免疫原性和有效性。然而,免疫介导性疾病患者对这些疫苗产生免疫反应的能力尚未确定。此外,免疫抑制药物如何影响疫苗诱导免疫的发展在很大程度上仍不清楚。

     特应性皮炎(AD)是一种慢性免疫介导的皮肤病,影响多达20%-30%的儿童和2%-10%的成年人。在患有严重合并症的AD患者和那些长期接受全身皮质激素治疗的患者中,发现与新冠肺炎相关的住院和死亡率负担增加。新冠肺炎基因疫苗治疗AD的疗效有待观察。在目前的研究中,williamhill asia 旨在评估AD患者接种新冠肺炎疫苗的频率、决定因素和疗效。次要终点是评估不同AD相关治疗方式对新冠肺炎疫苗效用的影响。

     williamhill asia 的目的是评估BNT162b2信使RNA疫苗在AD患者中的流行率,并评估其在预防严重急性呼吸综合征冠状病毒2(SARS-CoV-2)感染、新冠肺炎相关住院和死亡率方面的有效性。另外,一项专门的分析还检查了与AD相关的免疫抑制药物是否会影响疫苗的效力。

     使用以色列Clalit Heath Services的数据库进行了一项基于人群的队列研究,以跟踪成年AD患者。多因素COX和Logistic回归分析用于计算事件结局的调整危险比(HR)和优势比(OR)。

     截至2021年6月26日,以色列77682名成年AD患者中有58582人(75.4%)完成了两剂BNT162b2疫苗接种。成年期AD(调整后OR1.34;95%CI1.28~1.40;p<0.001)和中重度AD(调整后OR1.13;95%CI1.05~1.21;p=0.001)预示接种率增加。接种疫苗的AD患者感染SARS-CoV-2的风险(调整后HR,0.20;95%CI为0.16-0.26;p<0.001)、与新冠肺炎相关的住院风险(调整后HR为0.08;95%CI为0.04-0.18;p<0.001)以及新冠肺炎相关死亡率(调整后HR为0.04;95%CI为0.01-0.20;p<0.001)显著降低。暴露于免疫抑制药物(n=597;0.8%的患者)并未削弱疫苗接种后对SARS-CoV-2感染的保护(调整后的HR为0.95;95%CI为0.13-6.81;p=0.958)。

     在AD患者中,新冠肺炎疫苗接种对一系列与新冠肺炎相关的结果非常有效。在这项回顾分析中,免疫抑制药物没有削弱疫苗预防SARS-CoV-2感染的有效性。
