与传统疫苗相比,Heplisav-B疫苗为炎症性肠病 (IBD) 患者提供了更好的乙型肝炎 (HepB) 保护. 这种2剂量系列显示出更高的血清保护率,使其成为这个脆弱人群的潜在首选选择.
科学领域:
- 免疫学 免疫学 免疫学
- 胃肠病学 胃肠病学
- 疫苗学 疫苗学 疫苗学
背景情况:
- 患有炎症性肠病 (IBD) 的患者经常接受免疫抑制疗法,增加他们患乙型肝炎 (HepB) 等感染的风险.
- 标准的3剂复合型HepB疫苗在成年IBD患者中显示出低于最佳的血清保护率.
- 希普利萨夫-B是一种辅助的2剂量HepB疫苗,在一般成年人群中表现出增强的免疫性.
研究的目的:
- 评估Heplisav-B疫苗在IBD的成年患者中的免疫性和血清保护率.
- 为了比较Heplisav-B与IBD患者之前的HepB疫苗接种反应的疗效.
主要方法:
- 在缺乏HepB血清保护的成年IBD患者中进行了一项前性观察研究.
- 参与者接受了Heplisav-B疫苗系列,随后进行了对HepB表面抗体 (抗HBs) 的血清学测试.
- 血清保护被定义为抗HBs水平≥10 IU/mL;二次结果分析年龄,免疫抑制疗法和之前的疫苗不反应.
主要成果:
- 在85名参与者中,72%的人通过Heplisav-B获得了血清保护,平均抗HBs水平为48.7 IU/mL.
- 接受免疫抑制治疗的患者 (OR:0.34) 和之前对HepB疫苗无反应的患者 (OR:0.26) 实现血清保护的可能性较低.
- 七名没有反应者接受了额外的Heplisav-B剂量,其中2人获得了血清保护.
结论:
- 与传统的3剂量重组HepB疫苗相比,Heplisav-B在IBD患者中显示出更高的血清保护率.
- 2剂量Heplisav-B疫苗可能是成年IBD患者首选的疫苗接种策略.
- 需要进一步研究优化免疫抑制的IBD患者的HepB疫苗接种.
