BACKGROUND
This study had sought to assess the seroreactivity to the fish nematode spp. in a puerperal population, as well as to ascertain whether a correlation exists between maternal and cord blood levels.
METHODS
Blood samples were obtained from puerperal women and cord blood to measure specific anti- antigen IgG and IgE by ELISA. Non-parametric tests were used to compare two or more independent and related samples.
RESULTS
Of the 99 maternal serum samples assessed, 21 were positive on ELISA (21.2%). There were no significant differences in the mean ranks of IgG optical density levels between women who ate fish and those who did not (p = 0.456), those who ate raw fish and those who did not (p = 0.479), or between those who had allergic complaints and those who did not (p = 0.431).
CONCLUSION
Transplacental passage of antibodies occurred, leading to moderate correlation between maternal and cord blood serum levels.
背景
本研究旨在评估产后人群对鱼类线虫 spp. 的血清反应性，并确定母血和脐血水平之间是否存在相关性。
方法
采集产后妇女和脐血的血样，通过酶联免疫吸附测定法（ELISA）测量特异性抗抗原 IgG 和 IgE。采用非参数检验比较两个或多个独立及相关样本。
结果
在评估的 99 份母血样本中，21 份 ELISA 检测呈阳性（21.2%）。吃鱼的妇女与不吃鱼的妇女之间（p = 0.456）、吃生鱼的妇女与不吃生鱼的妇女之间（p = 0.479），以及有过敏症状的妇女与没有过敏症状的妇女之间（p = 0.431），IgG 光密度水平的平均秩次均无显著差异。
结论
抗体发生了经胎盘传递，导致母血和脐血血清水平之间存在中度相关性。
