摘 要:目的回顾性分析53例孕产妇Rh血型系统外的6个血型系统不规则抗体情况,分析其与新生儿溶血病发生的关联。方法微住凝胶检测技术结合抗人球蛋白(IgG+C3d)对19473名孕产妇进行不规则抗体筛查,对不规则抗体筛查阳性标本进行不规则抗体确认试验,得出不规则抗体类型及不规则抗体效价;不规则抗体类型确定实验:巯基乙醇(2-Me)对不规则抗体阳性标本血清进行灭活后测定IgG型不规则抗体效价,对比2次不规则抗体效价水平进行IgG,IgM类型确定。分娩时采集脐血进行溶血3项试验及总胆红素检测分析黄疸水平及新生儿溶血病发生。结果19473名孕产妇检测出53例Rh血型系统以外不规则抗体,阳性比例为0.27%,以MNS血型系统,Lewis血型系统为主;新生儿溶血病(HDN)发生率39.6%(21/53),不规则抗体类型分布:单独IgM型27例,单独IgG型7例,IgM+IgG混合型19例。低效价组(≤8)与高效价组(>8)总胆红素检测对比:高效价组显著高于低效价组(P<0.05);IgG抗体亚型情况:高效价组IgG1明显增高(P<0.05),低效价组IgG3增高明显(P<0.05),IgG1,IgG3和总胆红素之间均存在显著的正相关关系;IgG1+IgG3联合诊断HDN的曲线下面积为0.953,敏感度0.900,特异度0.967。结论孕产妇Rh血型系统以外不规则抗体分布以MNS血型系统,Lewis血型系统为主;Kell,Duffy,kidd 3个血型系统产生不规则抗体后发生新生儿溶血病比例较高;不抗体类型多以单独IgM型或IgM+IgG混合型,发生新生儿溶血性的几率不高;高效价或低效价有不良孕产史患者早期可以分型IgG分型,IgG1,IgG3结果异常的应纳入高危产妇围产期管理,定期检测。Objective To retrospectively analyze the irregular antibodies in 6 blood group systems other than the Rh blood group system in 53 pregnant women and analyze its correlation with the occurrence of hemolytic disease of the newborn(HDN).Methods 19473 pregnant women were screened for irregular antibodies by microgel detection technology combined with anti-human globulin(IgG+C3d),and the positive samples screened out were further confirmed to understand the types and titers of irregular antibodies.Irregular antibody type determination experiment:IgG type irregular antibody titer was determined after mercaptoethanol(2-Me)inactivated the serum of the irregular antibody positive specimen,and then IgG and IgM type were determined by comparing the titer levels of irregular antibody.Three hemolysis tests and total bilirubin tests were performed on umbilical cord blood during delivery to analyze the level of jaundice and the occurrence of HDN.Results 53 cases of irregular antibodies other than the Rh blood group system were detected in 19473 pregnant women,with a positive rate of 0.27%,mainly MNS and Lewis blood group system.The incidence of HDN was 39.6%(21/53).There were 27 cases of IgM,7 IgG,and 19 IgM+IgG.Comparison of total bilirubin detection between the low titer group(≤8)and the high titer group(>8):the latter was significantly higher than the former(P<0.05);IgG antibody subtypes:IgG1 of the latter significantly increased(P<0.05),and so was IgG3 in former(P<0.05).There was a significant positive correlation between IgG1,IgG3 and total bilirubin.The area under the curve of IgG1+IgG3 for HDN diagnosis,the sensitivity and specificity were 0.953,0.900,and 0.967,respectively.Conclusion Other than Rh blood group system,irregular antibodies are mainly distributed in MNS and Lewis blood group system.The incidence of HDN is higher in Kell,Duffy and Kidd blood group systems after producing irregular antibodies.Non-antibody types are mostly IgM type or IgM+IgG mixed,and the incidence of HDN is not high;Patients with poor mate
