摘要 目的探讨糖尿病酮症酸中毒(DKA)患儿外周血调节性T细胞(Treg)和胰岛B细胞功能的变化情况及两者的关系。方法 34例1型糖尿病患儿,根据有无并发DKA分为DKA组(24例)、非DKA组(10例),20例正常健康儿童作为正常对照组。采用流式细胞术检测外周血CD4+CD25+Treg百分率,化学发光法检测血清空腹C肽(FC-P)、胰岛素及糖化血红蛋白(HbA1c)水平。结果 DKA组和非DKA组外周血CD4+CD25+Treg百分率、胰岛素、FC-P低于正常对照组,HbA1c高于正常对照组(P<0.05);DKA组外周血CD4+CD25+Treg百分率、胰岛素和FC-P低于非DKA组,HbA1c高于非DKA组(P<0.05)。相关分析显示,CD4+CD25+Treg百分率与胰岛素、FC-P呈正相关(r=0.627、0.532,P<0.05),与HbA1c水平呈负相关(r=-0.708,P<0.05)。结论 DKA患儿外周血CD4+CD25+Treg百分率减低,可能参与了儿童DKA的发生和发展,与胰岛B细胞功能相关。
