JCC:重组带状疱疹疫苗在炎症性肠病患者中是安全的

2022-05-18 xuyihan MedSci原创

带状疱疹是一种常见病多发病,这是由水痘-带状疱疹病毒引起的疾病。这个病毒仅仅在我们人类之间传播。

疫苗作为医学史上最重要的发明之一,在人类与疾病的抗争进程中发挥了巨大作用。在新冠肺炎流行期间,疫苗也有力地遏制了其在人群中的传播。然而,由于疾病的影响,部分人群的疫苗接种相比于一般人群有所差别,比如进行免疫抑制治疗的炎症性肠病(IBD)患者。 炎症性肠病(IBD),即克罗恩病(CD)和溃疡性结肠炎(UC),是累及小肠和结肠的慢性炎症性疾病。作为一种免疫介导性疾病,IBD的治疗常常需要免疫抑制疗法。但是,免疫抑制可以增强一系列传染性病原体的易感性。炎症性肠病 [IBD] 患者感染带状疱疹 [HZ] 的风险增加。然而,IBD 患者中 HZ 的疫苗接种率很低。一个促成因素可能是害怕与疫苗接种相关的 IBD 发作。因此,本项研究目的是评估重组带状疱疹疫苗 [RZV] 是否与 IBD 发作有关。

这是一项回顾性队列研究,使用的数据来自退伍军人事务医疗保健系统 [VAHS]。主要的干预措施是接受RZV治疗。研究人员将这些暴露与RZV的患者与未暴露的个体随机匹配。主要观察结果是RZV后 90 天内 IBD 发作的发作情况。使用连续变量的t检验和分类变量的卡方检验比较组间的基线特征。条件逻辑回归用于估计优势比 [OR] 和 95% 置信区间 [CI]。

 

研究结果显示在符合条件的研究队列中,1677名患者接受了RZV。36 名患者(暴露组 20 人,未暴露组 16 人)通过病历回顾确认有疾病复发。IBD 发作的 90 天累积发病率在接种组和未接种组之间没有差异[暴露组为 1.2%,未接种组为 1.0%,p=0.503]。与 RZV 疫苗接种相关的 IBD 发作的 OR为 1.25 [95% CI:0.65–2.41]。

 

本项研究证实在 IBD患者队列中,RZV 的给药与 90 天内 IBD 发作的风险无关。这些发现应该会促使人们进一步使用这种高效疫苗。
