摘要： 目的研究抗体筛查阳性输血患者的抗体与Rh抗原分布情况。方法收集2019年10月1日—2022年12月31日中山大学孙逸仙纪念医院34 796例患者的不规则抗体筛查结果,以及抗体筛查阳性患者的抗体鉴定与Rh抗原分型结果,记录34 796例患者的年龄、性别、妊娠史、输血史等基本资料,分析各血型系统不规则抗体产生的阳性率及相关影响因素。结果 34 796例患者中,不规则抗体筛查阳性的患者237例,抗体筛查阳性率为0.68%。共检出不规则抗体260例,其中MNS系统83例（占31.93%）,Rh血型系统抗体70例（占26.93%）,Lewis血型系统14例（占比5.39%）。同种非特异性抗体79例,阳性率30.38%。同种特异性抗体中抗-E的占比最高,为20.77%;其次是抗-Mia,为20.39%。对237例抗体筛查阳性患者进行Rh抗原分型,CCDee抗原表型占比最高,为52.74%,其次是CcDEe占比29.16%。抗体筛查阳性率与性别、输血史、妊娠史有关,女性、有输血史、有妊娠史者的抗体筛查阳性率较高（P>0.05）。不同科室间抗体筛查阳性率比较差异有统计学意义（P>0.05）,其中风湿免疫科与血液科患者阳性率最高。结论抗-E、抗-Mia为主要的红细胞不规则抗体,不规则抗体的产生与性别、输血史、妊娠史有关,输血前进行不规则抗体筛查、鉴定及Rh抗原分型,有利于提高输血安全。

Abstract: Objective To explore the distribution of antibodies and Rh antigens in transfusion patients with positive antibodies screened in our hospital．Methods From October 1,2019 to December 31,2022,there were 34,796 patients undergoing irregular antibody screening in Sun Yat-sen Memorial Hospital of Sun Yat-sen University,antibody identification and Rh blood typing results of positive patients were collected．Meanwhile,the age,sex,pregnancy history,blood transfusion history and other basic data of 34 796 patients were collected,and the positive rate of irregular antibody production and related influencing factors of blood group system were analyzed．Results Among the 34,796 patients,237 patients were screened positive for irregular antibodies,and the antibody screening positivity rate was 0.68%．A total of 260 cases of irregular antibodies were detected,83 cases of MNS system,accounting for 31.93%;70 cases of Rh blood group system,accounting for 26.93%;14 cases of Lewis blood group system,accounting for 5.39%．There were 79 cases of homozygous non-specific antibodies,with a detection rate of 30.38%．The highest percentage of homo-specific antibodies was anti-E,accounting for 20.77%,followed by anti-Mia,accounting for 20.39%．Rh antigen typing was performed in 237 antibody-screening positive patients,and the highest percentage of CCDee antigen phenotype was 52.74%,followed by CcDEe with 29.16%．Antibody screening positive rate was correlated with gender,blood transfusion history and pregnancy history,and the positive rate was higher in female,patients with blood transfusion history and pregnancy history,and the difference was statistically significant（P>0.05）．There were differences in the positive detection rate of antibody-screening in different departments,and the differences were statistically significant（P>0.05）,and the highest positive rates were in Department of Rheumatology and Immunology and Hematology．Conclusions Anti-E,anti-Mia are the main erythrocyte irregular antibodies,and the production of irregular antibodies is related to gender,transfusion history and pregnancy history,and irregular antibody screening,identification and Rh antigen typing before transfusion are beneficial to improve transfusion safety．
