摘要
目的了解该地区孕妇ABO血型抗A(B)IgG抗体效价异常率,分析其在新生儿溶血病(HDN)中的意义。方法采用微柱凝胶法对4000例孕周20周以上、O型血孕妇(丈夫为非O型血)进行血清抗A(B)IgG抗体效价检测;对抗体效价大于1:64者所分娩新生儿进行HDN试验检测,分析抗体效价与HDN发病率的关系。结果 4000例孕妇中,血清抗A(B)IgG抗体效价大于1:64者有432例,异常率为10.8%(432/4000);295例血清抗A(B)IgG抗体效价大于1:64者所分娩的新生儿中,HDN发病率为53.9%(159/295)。结论随着血清IgG抗A(B)效价增高,HDN发病率也增高;产前抗体效价检测是可用于判断HDN发病风险的筛查指标。
Objective To analyze the abnormal rate of ABO blood group anti-A(B) IgG antibody titer in gravida in this area and its relationship with hemolytic disease of the newborn(HDN).Methods Microcolumn gel method was performed for the detection of antibody titer in 4 000 cases of gravidas.Neonatus,delivered by gravida with antibody titer more than 1:64,were detected with HDN tests.Relationship between antibody titer and the incidence rate of HDN was analyzed.Results The abnormal rate of antibody titer was 10.8%(432/4 000).In neonatus,delivered by gravida with abnormal antibody titer,the incidence rate of HDN was 53.9%(159/295).Conclusion The incidence rate of HND could increase with the increasing of the titer of anti-A(B) antibody in gravida.Detection of antibody titer before delivery might be an effective indicator for the screening of HDN.
