1197例患者呼吸道感染病原体IgM检测结果分析

Analysis on detection results of IgM of pathogens causing respiratory infections in 1197 patients

目的探讨9项呼吸道感染病原体IgM抗体检测在成人急性呼吸道感染中的作用,为临床提供早期诊断依据。方法选取成都军区昆明总医院呼吸道感染患者1 197例,通过9项呼吸道感染病原体IgM抗体试剂检测住院成人患者血清病原体抗体,分析9项呼吸道感染病原体在不同年龄段及性别患者血清中的检出情况。结果1 197例患者血清IgM抗体阳性共371例,总阳性率为30.99%(371/1 197);肺炎支原体(MP)阳性率最高,为16.96%(203/1 197);其次为乙型流感病毒(IFB),阳性率为16.21%(194/1 197);副流感病毒(PIV)、甲型流感病毒(IFA)阳性率分别为10.03%、7.44%。病原体合并感染170例,阳性率为14.20%(170/1 197),占阳性病例的45.82%(170/371)。结论昆明地区呼吸道感染的病原体主要为MP、IFB、PIV及IFA等,且病原体的检出率和年龄具有相关性。

Objective To investigate the role of 9 items of respiratory tract infectious pathogens IgM antibodies in adult respiratory tract infection to provide a basis for early diagnosis in clinical practice.Methods A total of 1197 patients of respiratory tract infection in our hospital were selected.The 9items of respiratory tract infectious pathogens serum IgM antibodies were detected and the detection results in different age periods and genders were analyzed.Results Among 1 197 adult patients,371 cases were the serum IgM antibody positive of respiratory pathogens,the total positive rate was 30.99%（371/1 197）.Mycoplasma pneumonia（MP）had the highest positive rate[16.96%（203/1 197）],followed by influenza virus type B（IFB）[16.21%（194/1 197）],respiratory parainfluenza virus（PIV,10.03%）and influenza virus type A（IFA,7.44%）.The pathogens combined infections were found in 170 cases with positive rate of 14.20%（170/1 197）,which accounted for 45.82%（170/371）of the positive cases.Conclusion MP and various type of influenza virus are the main pathogens in respiratory tract infection in Kunming area,moreover the detection rate of pathogens is correlated with age.
