摘要
目的 探讨乙型肝炎病毒 (HBV)感染的母亲对新生儿乙型肝炎 (简称乙肝 )基因疫苗免疫接种效果的影响。方法 按母亲是否有 HBV感染 ,将新生儿分为暴露组和非暴露组各 76名 ,追踪观察两组新生儿接种乙肝基因疫苗后 1、2和 7个月龄时的免疫效果 ,采用酶联免疫吸附试验(EL ISA)、聚合酶链反应 (PCR)法和测定吞噬细胞吞噬功能的化学发光法进行血液检测。结果 在两组新生儿系列血清中均未检出 HBV DNA和血清 HBV感染标志物 ,暴露组乙肝疫苗无应答率为 19.74 % (15 /76 ) ,而非暴露组乙肝疫苗免疫无应答率为 6 .5 8% (5 /76 ) ,两组比较 ,差异具有显著性 (χ2 =2 1.5 6 ,P <0 .0 1)。疫苗接种后 2个月和 7个月时 ,暴露组外周血吞噬细胞的吞噬功能明显下降。结论 母亲感染 HBV后对新生儿的吞噬细胞活性和抗 -
Objective To explore effect of maternal HBV infection on neonatal immunization with hepatitis B gene vaccine. Methods Prospective study was conducted in evaluation of immune effects with ELISA?PCR and the cellular phagocytosis was examined by luminolenhanced chemiluminescnce assay. Results Hepatitis B virus nucleotide (HBV DNA) and serological infectious markers were not found in neonatal series serum. The immunization protective rates in exposure and noexposure group were 80.3% (61/76) and 93.4% (71/76), respectively. After hepatitis B vaccinated, the cellular phagocytosis decreased obviously in 2nd and 7th month in exposed group. Conclusions Maternal HBV infection state at parturition might make some effects on neonatal anti HBs positive transformation.
