摘要
目的:分析ABO以外不规则血型抗体导致的新生儿溶血病(ABO-HDFN)的抗体特异性分布特征、实验室检测情况及其与临床的相关性。方法:选取2012年10月至2021年12月本院送检的非ABO-HDFN病例为研究对象,随机选取同期确诊为ABO-HDFN的病例作为对照组,对引起HDFN抗体特异性分布、总胆红素、直抗、母亲孕产史、患儿日龄、有无合并ABO-HDFN、是否换/输血等资料进行回顾性分析,分析江西地区非ABO-HDFN患者的特征。结果:江西地区非ABO-HDFN的检出率逐年升高,187例非ABO-HDFN病例中,检出Rh-HDFN比例最高,为94.6%;与对照组ABO-HDFN相比,非ABO-HDFN的直抗平均积分值更高、总胆红素峰值更高、持续时间长;抗M-HDFN可能出现病情严重但直抗弱阳性/阴性的情况,临床上易被漏检而延误治疗;不规则抗体的特异性、患儿性别、母亲既往生育史、有无合并ABO-HDFN等指标与是否需要换/输血治疗之间均无相关性(P>0.05)。结论:江西地区引起非ABO-HDFN的不规则抗体以Rh血型系统为主,MNS血型系统次之。了解HDFN疾病的特征、血清学特点及与临床指标的相关性,将有助于及时发现、治疗非ABO-HDFN,降低并发症危害。
Objective: To analyze the characteristics of antibody-specific distribution, laboratory detection results of hemolytic disease of the fetus and neonatal(HDFN) caused by irregular blood group antibodies other than ABO, and its correlation with the clinical situation. Methods: The non-ABO-HDFN cases in our hospital from October 2012 to December 2021 were selected as the research objects, and the cases diagnosed with ABO-HDFN in the same period were randomly selected as the control group, and the data of antibody specific distribution, total bilirubin, direct antibodies, maternal history, age of the children, the presence or absence of combined ABO-HDFN, and whether to exchange/transfuse blood were retrospectively analyzed. The characteristics of non-ABO-HDFN in Jiangxi province were analyzed. Results: The detection rate of non-ABO-HDFN in Jiangxi province increased. Among 187 non ABO-HDFN cases, the highest percentage of Rh-HDFN was detected(94.6%). Compared with the control group of ABO-HDFN, the non-ABO-HDFN had higher mean integral value of direct antibody, higher peak total bilirubin, and longer duration. Anti-M-HDFN may have severe disease but the direct antibody weak positive/negative, it was easy missed in clinical and delayed the treatment. There is no correlation between the specificity of irregular antibodies, the sex of the child, the mother′s previous childbirth history, the presence or absence of combined ABO-HDFN and the need for blood exchange/transfusion(P>0.05). Conclusion: The irregular antibodies of causing non ABO-HDFN in Jiangxi area are mainly Rh blood group system, followed by MNS blood group system. Understanding the characteristics of HDFN disease, serological features and the correlation with clinical indexes will help to detect and treat non ABO-HDFN in time and reduce the risk of complications.
