儿童百日咳IgG抗体水平检测结果相关分析

Children pertussis IgG antibody levels analysis

目的了解儿童中血清百日咳IgG抗体水平及百日咳IgG抗体阳性患者的血常规中白细胞和淋巴细胞百分比的变化,以便于根据患者的临床症状与检查结果进行诊断与治疗。方法随机选取山东省立医院就诊的485例儿童作为检测对象,对其进行百日咳IgG抗体(PT-IgG)检测及血细胞检测。结果 PT-IgG水平阳性为90例,阳性率为18.6%,其中以8~<10岁儿童百日咳IgG抗体水平最高,2~<4岁次之,10~14岁最低,百日咳抗体水平阳性的患者中白细胞总数达到20×109/L以上及淋巴细胞百分比达到60%以上的为19例,阳性率为21.1%,其中6~<8岁阳性率最高,10~14岁最低。结论 PT-IgG抗体水平高在10岁以下儿童发生率较高,白细胞及淋巴细胞的变化主要在8岁以下儿童,一般此病病程可长达2~3个月,因此需要及早进行诊断与治疗,对儿童进行百日咳疫苗的加强免疫也是非常有必要的。

Objective In order to know the changes of serum pertussis IgG antibody level and the percentage of white blood cells and lymphocytes in blood routine of children with IgG antibody positive,it is easy to diagnose and treat according to the clinical symptoms and examination results of children.Methods 485 cases of children in Shangdong Provincial Hospital were randomly enrolled as the test subjects,and pertussis antibody IgG(PT-IgG)detection and blood cell detection were carried out.Results The levels of Pertussis IgG antibody were positive in 90 cases,the positive rate was 18.6%,pertussis IgG antibody level of children aged 8-<10 years old was the highest,2-<4 years old took the second place,10-14 years old were with the lowest levels.Among the patients with positive pertussis antibody levels,white blood cells in total were more than 20×10 9/L and lymphocyte percentage reached more than 60%in 19 cases,the positive rate was 21.1%,of which 6-<8 years old the highest positive rate was 10-14,the lowest.Conclusion IgG antibody of pertussis incidence is higher in children under 10 years old,the changes of white blood cells and lymphocytes mainly in children under the age of 8,the general course of the disease can be up to 2-3 months,so the need for early diagnosis and treatment,strengthen the immunity of pertussis vaccine is very necessary for children.
