Abstract

BACKGROUND

It has previously been shown in an uncontrolled study that the IgE response to vaccine antigens is downregulated by co-vaccination with cellular Bordetella pertussis vaccine.

METHODS

In the present study, we compared in a controlled trial the humoral immune response to diphtheria toxoid (D) and tetanus toxoid (T) in relation to co-vaccinated cellular or acellular B pertussis vaccine. IgE, IgG4, and IgG to D and T were analyzed at 2, 7, and 12 months of age in sera of children vaccinated with D and T (DT, N = 68), cellular (DTPw, N = 68), 2- or 5-component acellular B pertussis vaccine (DTPa2, N = 64; DTPa5, N = 65).

RESULTS

One month after vaccination, D-IgE was detected in 10% sera of DTPw-vaccinated children, whereas vaccination in the absence of whole-cell pertussis resulted in 50%-60% IgE positivity. Six months after vaccination, the IgE antibody levels were found to be more persistent than the IgG antibodies. These diphtheria findings were mirrored by those for tetanus. Only minor differences between vaccine groups were found with regard to D-IgG and T-IgG. No immediate-type allergic reactions were observed.

CONCLUSION

Cellular (but not acellular) B pertussis vaccine downregulates IgE to co-vaccinated antigens in infants. We assume that the absence of immediate-type allergic reactions is due to the high levels of IgG antibodies competing with IgE antibodies.

摘要

背景

先前的一项非对照研究表明,细胞百日咳疫苗与疫苗抗原共同接种可下调对疫苗抗原的 IgE 应答。

方法

在本研究中,我们通过对照试验比较了在婴儿中同时接种细胞型或无细胞型百日咳疫苗与全细胞型百日咳疫苗时,对白喉类毒素(D)和破伤风类毒素(T)的体液免疫应答。在接种 D 和 T(DT,N=68)、细胞型(DTPw,N=68)、2 或 5 组分无细胞型百日咳疫苗(DTPa2,N=64;DTPa5,N=65)的儿童血清中,于 2、7 和 12 月龄时分析 IgE、IgG4 和 IgG 对 D 和 T 的应答。

结果

接种 DTPw 疫苗的儿童中,1 个月后有 10%的血清中可检测到 D-IgE,而全细胞百日咳疫苗缺失时,IgE 阳性率为 50%-60%。接种 6 个月后,发现 IgE 抗体水平比 IgG 抗体更持久。这些白喉发现与破伤风的发现相似。关于 D-IgG 和 T-IgG,各组之间仅发现了微小差异。未观察到即刻型过敏反应。

结论

细胞型(而非无细胞型)百日咳疫苗可下调婴儿共同接种的抗原的 IgE。我们假设即刻型过敏反应缺失是由于 IgG 抗体水平高,与 IgE 抗体竞争所致。
