深圳市5918例呼吸道感染患者9种呼吸道病原体IgM抗体检测分析

目的分析深圳市患者9种呼吸道病原体的感染特点和流行趋势。方法收集该院就诊的具有急性呼吸道感染症状的患者5 918例,采用间接免疫荧光法检测9种呼吸道病原体的IgM抗体,包括嗜肺军团菌1型(LP1)、肺炎支原体(MP)、Q热立克次体(COX)、肺炎衣原体(CPn)、腺病毒(ADV)、呼吸道合胞病毒(RSV)、甲型流感病毒(INFA)、乙型流感病毒(INFB)、副流感病毒(PIVs),并对结果进行统计学分析。结果 5 918份血清标本中共检出IgM抗体阳性1 376份,总阳性率为23.25%,其中MP阳性率最高(15.19%),其次为INFB(8.11%),其余几种病原体阳性率较低,混合感染阳性率为4.29%。女性患者中MP、INFB和PIVs IgM抗体的阳性率显著高于男性患者(P0.001)。MP、INFB和PIVs在不同季节中的阳性率不同,其差异具有统计学意义(P0.001)。0~14岁组MP、ADV和INFB IgM抗体阳性率显著高于14~60岁组和60岁(P0.05)。婴幼儿(0~14岁)患者MP、CPn、ADV、RSV、INFB和PIVs的阳性率与年龄密切相关(P0.05)。结论引起深圳市人群非典型肺炎的主要呼吸道病原体,以MP和INFB为主,9种病原体具有各自的感染特点和流行趋势。

Nine pathogens IgM antibody detection of 5918 respiratory tract infections in Shenzhen city

Objective To analyze the infection characteristics and epidemic trend of 9 respiratory pathogens in Shenzhen popula-tion .Methods The 5918 patients with acute respiratory tract infection were collected ,indirect immunofluorescence was used to de-tect the IgM antibody of 9 respiratory pathogens ,including legionella pneumophila type 1 (LP1) ,mycoplasma pneumoniae (MP) , rickettsia Q (COX) ,rickettsia and chlamydia pneumoniae (CPn) ,adenovirus (ADV) ,respiratory syncytial virus (RSV) ,influenza A virus (INFA) ,influenza B virus (INFB) ,parainfluenza virus (PIVs) ,the results were analyzed statistically .Results A total of 1376 samples were detected at least one pathogen in 5918 serum samples ,the total positive rate was 23 .25% .The positive rate of MP was the highest (15 .19% ) ,followed by the INFB (8 .11% ) .The positive rates of other pathogens were relatively low .The mixed infection positive rate was 4 .29% .The positive rates of MP ,INFB and PIVs in women were significantly higher than those in men(P<0 .001) .The positive rates of MP ,INFB and PIVs were different in different seasons ,the differences were statistically sig-nificant(P<0 .001) .The positive rates of MP ,ADV and INFB in 0 to 14 years old group were significantly higher than those in >14 to 60 years old group and >60 years old group(P<0 .05) .The positive rates of MP ,CPn ,ADV ,RSV ,INFB and PIVs were closely related with age in infant and children (0 to 14 years old)(P<0 .05) .Conclusion The main respiratory pathogens of SARS in Shenzhen city were MP and INFB ,the 9 pathogens had their own infection characteristics and epidemic trend .
