目的探讨儿童过敏性鼻炎(allergic rhinitis,AR)和支气管哮喘(bronchial asthma,BA)患儿外周血高迁移率族蛋白B1(high mobility group box 1,HMGB1)水平与辅助性T细胞17(T helper 17 cell,Th17)和调节性T细胞(regulatory T cell,Treg)...目的探讨儿童过敏性鼻炎(allergic rhinitis,AR)和支气管哮喘(bronchial asthma,BA)患儿外周血高迁移率族蛋白B1(high mobility group box 1,HMGB1)水平与辅助性T细胞17(T helper 17 cell,Th17)和调节性T细胞(regulatory T cell,Treg)的比例(Th17/Treg)的相关性。方法采用前瞻性研究方法,选取2023年3月至12月在解放军总医院第七医学中心门急诊就诊患儿及健康体检者共113例作为研究对象,按照临床症状分成健康对照组(n=25)、过敏性鼻炎组(AR组,n=28)、支气管哮喘组(BA组,n=31)和两者并有组(AR+BA组,n=29),比较4组肺功能、免疫球蛋白E(immunoglobulin E,IgE)、白细胞介素(interleukin,IL)-17、HMGB1水平和Th17/Treg比例。统计学方法采用t检验、方差分析和Pearson相关性分析。结果各组的第1秒用力呼气容积(forced expiratory volume in the first second,FEV1)的结果显示,健康对照组高于AR组、BA组和AR+BA组[(96.4±2.5)%、(90.7±4.9)%、(88.6±4.1)%、(82.1±5.5)%,F=47.193,P值均<0.001],显示AR和BA患儿肺功能可能变差。AR组、BA组和AR+BA组HMGB1水平高于健康对照组[(30.4±12.4)mg/L、(47.2±17.8)mg/L、(51.4±21.8)mg/L、(4.3±2.1)mg/L,F=48.896,P值均<0.001]。AR组、BA组和AR+BA组Th17/Treg比例高于健康对照组(0.68±0.14、0.71±0.14、1.36±0.40、0.30±0.07,F=105.547,P值均<0.001)。Pearson相关性分析结果显示,HMGB1与Th17(r=0.521,P<0.001)、Th17/Treg(r=0.419,P<0.05)、IgE(r=0.502,P<0.05)、IL-17(r=0.472,P<0.05)呈正相关,与FEV1(r=-0.645,P<0.001)呈负相关。结论在儿童AR合并BA的发病过程中,HMGB1水平及Th17细胞百分比增加,而Treg细胞百分比降低,Th17/Treg比例存在失衡的情形,HMGB1水平与Th17细胞百分比、Th17/Treg比例、IgE、IL-17及FEV1存在一定的相关性,HMGB1和Th17/Treg的动态平衡可能通过影响细胞因子的表达而起到一定的调节作用。展开更多
