摘要

目的：探讨江苏苏州地区呼吸道感染住院患儿肺炎支原体（MP）流行病学特征，为临床合理诊治MP感染提供参考。方法：收集2015-2020年苏州大学附属儿童医院12 401例呼吸道感染住院患儿的痰标本，采用荧光定量聚合酶链式反应（PCR）法检测MP-DNA，酶联免疫吸附试验（ELISA）法检测血清特异性MP抗体IgM，并分析MP检出情况。结果：12 401例住院患儿中，MP检出率30.76%（3 814/12 401），其中女性患儿MP检出率高于男性（c2=72.585，P<0.01）。<6个月、≥6个月~1岁、>1~3岁、>3~7岁、>7岁患儿MP检出率分别为8.72%、20.89%、34.57%、48.98%、65.21%，MP检出率随年龄增长逐渐升高（c2=1 883.359，P<0.01）。春夏秋冬MP检出率分别为26.61%、32.85%、35.98%、27.02%，夏秋季MP检出率高于冬春季（c2=92.064，P<0.01）。2015-2020年，2016年夏季为MP检出率最高季节（52.89%），2020年冬季为MP检出率最低季节（15.79%）。苏州地区2016年MP检出率45.06%为近6年来最高，2020年22.42%为最低。结论：苏州地区住院患儿呼吸道MP感染处于较高水平，随年龄增长MP检出率逐渐升高，夏秋季为MP感染高发季，新发呼吸道传染病可能对传统呼吸道病原体流行有一定影响。

Abstract

Objective: To probe into the epidemiological characteristics of Mycoplasma pneumoniae (MP) in hospitalized children with respiratory tract infection in Suzhou

Jiangsu

and provide reference for the rational diagnosis and treatment of MP infection. Methods: Sputum specimens of 12

401 cases of hospitalized children with respiratory tract infection from 2015 to 2020 in Children’s Hospital of Soochow University were collected. MP-DNA was detected by fluorescence quantitative polymerase chain reaction (PCR). Serum specific MP antibody IgM was detected by enzyme-linked immunosorbent assay (ELISA)

and the detection of MP was analyzed. Results: Among the 12

401 hospitalized children

the detection rate of MP was 30.76% (3

814/12

401)

and the detection rate of MP in female children was higher than that in male children (2=72.585

P<0.01). The detection rates of MP were respectively 8.72%

20.89%

34.57%

48.98% and 65.21% in children <6 months

≥6 months to 1 year old

>1 to 3 years old

>3 to 7 years old

and >7 years old

MP detection rate increased with age (2=1

883.359

P<0.01). The detection rate of MP in spring

summer

autumn and winter were respectively 26.61%

32.85%

35.98% and 27.02%. The detection rate of MP in summer and autumn was higher than that in winter and spring (2=92.064

P<0.01). From 2015 to 2020

the summer of 2016 was the season with the highest detection rate of MP (52.89%)

and the winter of 2020 was the season with the lowest detection rate of MP (15.79%). The detection rate of MP in Suzhou in 2016 was 45.06%

which was the highest in the past 6 years

and the lowest in 2020 at 22.42%. Conclusion: Respiratory tract MP infection in hospitalized children in Suzhou is at a high level

and the detection rate of MP gradually increases with age. Summer and autumn are the peak seasons of MP infection. New respiratory infectious diseases may have a certain impact on the prevalence of traditional respiratory pathogens.
