Hepatitis B vaccination is strongly recommended for all infants and children but also for adults who are at risk of HBV infection. Attempts to immunize patients with liver cirrhosis have been proven relatively ineffective, and several strategies have already been used to improve the immune response in this group. The primary aim of this review is to examine, discuss, and summarize the immunogenicity of hepatitis B vaccination in patients with liver cirrhosis. MEDLINE search identified 11 studies (n = 961). The dose of the vaccine and the schedule of the vaccination varied. The response rates to the HBV vaccination ranged from 16% to 87% among patients with cirrhosis regardless of the number and vaccine dose. In particular, patients who received the standard dose of vaccination achieved seroprotection rates ranged from 16% to 79% (mean response rate 38%) and those who received a double dose achieved relatively better seroprotection rates (range: 26%-87%; mean response rate 53%). The overall mean response rate to the HBV vaccination was 47%. In conclusion, cirrhotic patients achieve lower seroprotection rates after the completion of HBV vaccination series. Several strategies have tried to improve the immunogenicity; however, there is a great need for additional studies to further explore (1) the immune response in relation to poor vaccination responsiveness confounding factors, (2) novel strategies to improve immunogenicity, and (3) the immune mechanism underlying the differences in response rates to HBV vaccination.
乙型肝炎疫苗强烈建议为所有婴儿和儿童接种,但也建议为有乙型肝炎病毒感染风险的成年人接种。尝试为肝硬化患者进行免疫接种已被证明效果相对较差,已经使用了几种策略来改善该人群的免疫反应。本综述的主要目的是检查、讨论和总结乙型肝炎疫苗在肝硬化患者中的免疫原性。通过 MEDLINE 搜索确定了 11 项研究(n=961)。疫苗剂量和接种方案各不相同。无论接种疫苗的次数和剂量如何,肝硬化患者的乙型肝炎疫苗接种反应率范围为 16%至 87%。特别是,接受标准剂量疫苗接种的患者获得血清保护率范围为 16%至 79%(平均反应率为 38%),而接受双倍剂量疫苗接种的患者获得相对较好的血清保护率(范围:26%-87%;平均反应率为 53%)。乙型肝炎疫苗接种的总体平均反应率为 47%。总之,肝硬化患者在完成乙型肝炎疫苗接种系列后获得的血清保护率较低。已经尝试了几种策略来提高免疫原性;然而,非常需要进一步的研究来进一步探讨(1)与疫苗接种反应不良相关的混杂因素的免疫反应,(2)改善免疫原性的新策略,以及(3)对乙型肝炎疫苗接种反应率差异的免疫机制。
