Abstract:
【Objective】 To observe the distribution of non-ABO-HDN and its clinical relevance, so as to provide reference for clinical diagnosis and treatment. 【Methods】 A total of 287 cases of non-ABO-HDN recorded during January 2012 to August 2022 were enrolled and tested in our laboratory. The correlation between maternal history of blood transfusion, pregnancy, unexpected antibody titers, gender, ABO-HDN and transfusion therapy was analyzed by chi-square test. 【Results】 All 287 cases of non-ABO-HDN involved 13 kinds of unexpected antibodies of 6 blood group systems. Rh-HDN accounted for 96.17% (276/287), and anti-D-HDN accounted for 47.04% (135/287). The proportion of non-ABO-HDN patients without ABO-HDN requiring exchange/transfusion was significantly higher than that of non-ABO-HDN patients with ABO-HDN(P<0.05). The ratio of need for exchange/transfusion in the high titer group (>8) was significantly higher than that in the low titer group (≤8) (P<0.05). There was no significant difference in gender, mother′s history of blood transfusion, pregnancy and whether or not to exchange/transfusion (severity of illness). 【Conclusion】 Understanding the characteristics of non-ABO-HDN and the specific distribution of unexpected antibodies, the correlation between various factors and diseases and their clinical significance are conductive to timely taking necessary intervention measures and reducing the risk of complications.
