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), six donors were previously vaccinated (anti-HBs+). We investigated the differences in viral kinetics and immune responses in vaccinated and non-vaccinated 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=0.004). In unvaccinated individuals, IP-10, IL-10, MIP-1β and 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-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.

抽象

背景。 B型肝炎病毒(HBV) DNA , HBV表面抗原( HBsAg)的,表面的抗体(抗-HBs )和核心抗原(抗-HBc )血液和血浆供体筛查允许收购HBV尽管以前的乙肝疫苗的个体识别。

方法。 14 HBV急性感染捐助的面板( HBV-DNA-positive/anti-HBc-negative ) , 6个捐助者以前接种过(抗-HBs ) 。我们研究了病毒动力学和免疫反应的接种和未接种疫苗的个体差异。串行样品进行了表征, HBV DNA和血清学标志物和39因子。

的结果。病毒负荷增加的速率减弱,并更迅速地清除病毒接种的个体(P = 0.004 ) 。在未接种疫苗的个体中, IP -10, IL-10, MIP-1β和sIL -2Rα水平通常在病毒血症高峰时间升高。相比之下,接种疫苗的人士有更早的峰值发生在低得多的病毒载量,恰好与回忆的抗-HBs反应和清除病毒血症IL-10和IP - 10的回应。

结论。有先天和适应性免疫与以前接种的感染者,可能解释抑制病毒血症疫苗的突破感染的早期干预。虽然突破感染发生在部分保护的疫苗接种者,接种疫苗可能有助于早期控制的复制,免疫激活限制,防止临床显着的急性和慢性HBV感染者发展。
