1、中国现代医生2014年11月第52卷第31期·临床研究·肺炎支原体肺炎患儿免疫功能的临床分析陆晓萍孙飞袁哲锋z1.浙江省嘉兴市第一医院儿科,浙江嘉兴314000;2.浙江大学医学院附属儿童医院,浙江杭州310003【摘要】目的研究不同程度的肺炎支原体肺炎患儿T细胞亚群、免疫球蛋白水平变化,探讨其免疫功能以为临床治疗提供依据。方法用流式细胞仪检测肺炎支原体肺炎患儿急性期(重症组、普通组)和正常对照组儿童外周血T细胞亚群,用免疫比浊法检测血清IgA、IgM、IgG水平。结果肺炎支原体肺炎重症组T细胞亚群CD3+、CD4+.CD4+/CD8低于普通组和对照组(P2、CD3、CD4+.CD47CD8低于对照组(P<0.01);CD8重症组高于普通组(P<0.O1),而在普通组和对照组差异无统计学意义(P>0.05)。普通组和重症组肺炎血清IgA、IgM、IgG水平均高于正常对照组(P<0.01),但IgG重症组低于普通组,差异有统计学意义(P<0.01)。结论肺炎支原体肺炎患儿存在细胞免疫和体液免疫功能失调,检测T细胞亚群、免疫球蛋白水平,有利于判断肺炎支原体肺炎患儿病情,为临床应用免疫调节剂提供理论依据。[关键词】肺炎支原体肺炎;T细胞亚群;免疫球蛋白;儿童[中图分类号】R725.6【文献标识码】B【文章编号】1673—9701(2014)31—3、0015—03ClinicalsignificanceofimmunefunctionofthechildrenwithmycoplasmapneumonlaepneumoniaLUXiaopinfSUNFeilYUANZhefen1.DepartmentofPediatrics,theFirstHospitalofJiaxingCityinZhejiangProvince,Jiaxing314000,China;2.Children’SHospitalAfiliatedtoZhejiangUniversityMedicalCollege,Hangzhou310003,China[Ab4、stract】0bjectiveTostudythelevelsofT-LymphocytesubsetsandImmunoglobulinofchildrenwithvaryingde-greesofmycoplasmapneomoniaepneumonia,discussedtheimmunityfunctionandprovideabasisforclinicaltreat—ment.MethodsPeripheralbloodsampleswerecollectedfromthechildrenwithmycoplasmapneumoniaepneumoniaandhealth5、ychildren.ThenT-Lymphocytesubsetsweredetectedbyflowc)rtometry,andtheIgA,IgM,IgMandIgGweretestedbytheimmunoturbidimetrieassay.ResultsThepercentagesofT-LymphocytesubsetsCD3,CD4,CD4qCD8inseveremycoplasmapneumoniaepneumoniagroupwerelowerthanthoseincontrolandmildgroup(P<0.O1),thepercentagesofT-Lympho6、cytesubsetsCD3,CD4,CD4YCD8inmildgroupwerelowerthanthoseincontrolgroup(P<0.01),CD8inseveremycoplasmapneumoniaepneumoniagroupwerehigherthanmildgroup(P<0.01),butthepercentagesofCD8werenotsignificantlydifferentbetweencontrolandmildgroup(O.05).TheconcentrationsofIgA,IgMandIgGinsevergroupandmildgroupw7、erehigherthanthoseincontrolgroupf尸l<0.01).ButthepercentagesofIgGinsevergroupwerelowerthanthoseincontrol,thedifferencewerestatisticallysignificantW
