Abstract

Background. Blood and plasma donor screening for hepatitis B virus (HBV) DNA, HBV surface antigen (HBsAg), and antibodies to surface (anti-HBs) and core (anti-HBc) antigens allows identification of individuals who acquired HBV despite previous HBV vaccination.

Methods. Of 14 HBV acute infection donor panels (HBV-DNA-positive/anti-HBc-negative), 6 donors were previously vaccinated (anti-HBs+). We investigated the differences in viral kinetics and immune responses in vaccinated and nonvaccinated individuals. Serial specimens were characterized for HBV DNA and serological markers and 39 cytokines.

Results. The rate of viral load increase was blunted, and virus was cleared more rapidly in vaccinated individuals (P = .004). In unvaccinated individuals, induced protein 10 (IP-10), interleukin 10 (IL-10), macrophage inflammatory protein 1β (MIP-1β), and soluble interleukin 2Rα (sIL-2Rα) levels were commonly elevated at the time of peak viremia. In contrast, vaccinated individuals had earlier peaks in IL-10 and IP-10 responses that occurred at much lower viral loads and coincided with anamnestic anti-hepatitis B surface (HBs) responses and clearance of viremia.

Conclusion. There is earlier engagement of innate and adaptive immunity in infected subjects with previous vaccination, possibly explaining suppressed viremia in vaccine breakthrough infections. Although breakthrough infections occur in partially protected vaccine recipients, vaccination likely contributes to early control of replication, limiting immune activation and preventing development of clinically significant acute and chronic HBV infection.

摘要

背景。血液和血浆供体筛查乙型肝炎病毒(HBV )的DNA ,乙肝病毒表面抗原(HBsAg )和抗体表面(抗-HBs )和核心(抗-HBc )抗原可以识别谁收购了乙肝病毒,尽管以前乙肝疫苗接种的个人。

方法。 14乙肝病毒急性感染供体面板( HBV-DNA-positive/anti-HBc-negative )中, 6捐助者以前接种过疫苗(抗-HBs + ) 。我们调查的病毒动力学和免疫反应的差异在接种和未接种的个体。连续的标本进行了表征为HBV DNA和血清学标志物和39细胞因子。

结果。病毒负荷增加的速度减弱,而病毒在接种的个体( P = 0.004 )的清除速度更快。在未接种疫苗的个体,诱导蛋白10 (IP -10) ,白细胞介素-10(IL -10),巨噬细胞炎性蛋白1β( MIP-1β )和可溶性白细胞介素2Rα (中sIL -2Rα )水平通常升高至峰值病毒血症的时间。与此相对,接种的个体中有IL-10和其在低得多的病毒负荷发生和正好与回忆抗乙肝表面( HBs)中的反应和病毒血症的间隙中IP-10的反应早期峰值。

结论。有较早的感染者与以前的疫苗接种先天和适应性免疫的参与,可能解释在疫苗的突破感染抑制病毒血症。虽然突破感染发生在部分保护接种者,接种疫苗可能有助于早期控制的复制,限制了免疫激活和防止临床上显著急性和慢性HBV感染的发展。
