摘　　要：目的 探讨反复输血地中海贫血儿童血清免疫球蛋白水平变化及其与迟发性溶血性输血反应(delayed hemolytic transfusion reactions, DHTR)的相关性。方法 收集2022年6月-2023年4月期间到本院接受输血治疗的地中海贫血儿童(观察组)及健康体检儿童(对照组)血清标本,运用流式细胞仪CBA多因子定量检测技术,检测血清免疫球蛋白(IgG亚类、IgM、IgA、IgE、IgD)水平,比较2组儿童血清免疫球蛋白差异;按照不同输血次数分为4组:≤10次、11~30次、31~50次、>50次,各组采用单因素方差分析比较不同输血次数与血清免疫球蛋白水平之间的差异;将DHTR的地中海贫血儿童分为溶血组,未发生DHTR的地中海贫血儿童分为非溶血组,比较2组儿童血清免疫球蛋白(IgG亚类、IgM、IgA、IgE、IgD)之间的变化,探讨反复输血的地中海贫血儿童血清免疫球蛋白与DHTR的相关性。结果 血清免疫球蛋白IgG1、IgG3、IgG4、IgA观察组明显高于对照组,分别增加了(2.07±2.12)、(0.67±2.03)、(0.30±0.37)、(6.04±11.40)mg/mL,IgD观察组明显低于对照组,降低了(0.03±0.01)mg/mL,P<0.05;IgG2、IgM、IgE 2组之间,P>0.05。输血次数与血清免疫球蛋白之间的相关性:随着输血次数增加,IgG1、IgG4均明显增高,4组IgG1依次增加(0.30±0.62)、(0.41±0.51)、(3.60±3.48)mg/mL,IgG4依次增加(0.12±0.13)、(0.22±0.07)、(0.21±0.38)mg/mL,IgG2、IgM、IgD明显降低,4组IgG2、IgM、IgD依次降低(0.91±1.50)、(0.14±0.10)、(0.05±0.05)mg/mL,与输血次数之间有显著差异性,P<0.05;IgG3、IgA、IgE与输血次数之间无显著差异性,P>0.05。IgG1、IgG3、IgG4溶血组明显高于非溶血组,分别增加了:IgG1(4.44±3.41),IgG3(0.73±1.26),IgG4(0.52±0.40)mg/mL,IgD溶血组明显低于非溶血组,降低了(0.00±0.06)mg/mL,P<0.05;IgG2、IgM、IgA、IgE溶血组与非溶血组之间,P>0.05。结论 反复输血的地中海贫血儿童血清免疫球蛋白水平异常;反复输血的地中海贫血儿童不Objective To study the changes in serum immunoglobulin levels in children with thalassemia who undergo repeated blood transfusions and explore their correlation with delayed hemolytic transfusion reactions(DHTR).Methods Serum samples from children with thalassemia who received blood transfusion treatment from June 2022 to April 2023(observation group)and healthy children who underwent physical examination(control group)in our hospital were collected.The levels of serum immunoglobulins(IgG subtype,IgM,IgA,IgE and IgD)were detected using flow cytometry CBA multi-factor quantitative detection technology,and the differences between the two groups were compared.The children were divided into 4 groups according to different transfusion numbers:≤10 numbers,11-30 numbers,31-50 numbers and>50 numbers,and the differences between different blood transfusion numbers and serum immunoglobulin levels in each group were compared using one-way analysis of variance(ANOVA).Children with thalassemia with DHTR were in the hemolysis group,and children with thalassemia who did not experience DHTR were in the non-hemolysis group.The changes in serum immunoglobulins(IgG subtypes,IgM,IgA,IgE and IgD)between the two groups were compared to explore the correlation between serum immunoglobulins in thalassemia children with repeated transfusion and DHTR.Results The levels of IgG1,IgG3,IgG4 and IgA in the observation group were significantly higher than those in the control group,with the increase of(2.07±2.12),(0.67±2.03),(0.30±0.37)and(6.04±11.40)mg/mL,respectively,while the level of IgD in observation group was significantly lower than that in the control group,with a decrease of(0.03±0.01)mg/mL,P<0.05.No significant difference was noticed in IgG2,IgM and IgE between the groups(P>0.05).IgG1 and IgG4 both significantly increased with the number of blood transfusions.The IgG1 in the 4 groups increased sequentially as(0.30±0.62),(0.41±0.51)and(3.60±3.48)mg/mL,and IgG4 increased sequentially as(0.12±0.13),(0.22±0.07)and(0.21±0.38)m
