摘要: 目的 探索血小板抗体初筛强阳性患儿抗体效价分布情况及影响因素。方法 收集北京儿童医院2019年1月~2021年3月期间采用固相凝集法检测血小板抗体共21 230例,结果其中抗体强阳性(4+)患儿60例。对强阳性血清倍比稀释后采用同样方法检测血小板抗体效价。按性别、年龄、有无输血史、疾病进行分组并比较各组效价差异。结果 60例患儿效价分布范围2~64,其中效价为2、4、8、16、32、64的患儿分别为5例(8.33%)、8例(13.33%)、15例(25.00%)、21例(35.00%)、 9例(15.00%)、2例(3.33%);血小板抗体效价在不同年龄、性别、输血史和不同疾病组间差异均无统计学意义(P>0.05)。结论 儿科患者血小板抗体效价为8~16者占比较多,但效价高低与性别、年龄、有无输血史和临床疾病差异无统计学意义。

Abstract: Objective To explore the titer distribution and influencing factors of children with preliminary positive platelet antibody screening. Methods A total of 21 230 cases of platelet antibodies were detected by solid phase agglutination method from January 2019 to March 2021 in Beijing Children's Hospital,and 60 children were strong positive (4+) of platelet antibody screening. The titers of the positive samples were tested by continuous dilution and solid phase agglutination. Then the differences of the titers were compared in different groups which were divided according to gender, age, blood transfusion history and diseases. Results The titer distribution range of 60 children was 2, 4, 8, 16, 32 and 64, which were 5 cases (8.33%), 8 cases (13.33%), 15 cases (25.00%), 21 cases (35.00%), 9 cases (15.00%) and 2 cases (3.33%) respectively. No significant differences among these groups (P>0.05) were found. Conclusion The titer range of children with strong positive platelet antibody is 8 to 16, but the level of titer is not statistically related to gender, age, blood transfusion history and clinical diseases.
