Etiological Analysis Of 1321 Hospitalized Children With Community Acquired Pneumonia

Objective To understand the hospital pediatric community-acquired pneumonia(CAP)distribution of pathogens,and provide reference forclinical rational use of drugs.Methods Collected in the respiratory department of our hospital inSeptember 2015 to 2016 August meet the diagnostic criteria of small cap 1 month to 14 years old hospitalized children 1321 cases,divided by age is less than or equal to 1 years old,1～3 years old,is more than or equal to 3 year old group,the qualified sputum specimens for bacterial culture and drug sensitive test,fiberoptic bronchoscopy finger syndrome,specimens from the alveolar lavage fluid for bacterial culture and drug sensitivity test and fluorescence quantitative PCR detection of mycoplasma pneumoniae DNA.At the same time detect virus and mycoplasma pneumoniae DNA by nasophary swabs.Results1.The following data were combined with clinical excluding false positive cases results:1321 cases,pathogen positive cases for 803 cases and positive rate of pathogen was 60.79%and simple pathogen infection in 539 patients(40.80%),mixed with the other pathogen infection 264 cases(19.99%),the unexplained 518 cases(39.21%).Virus positive rate was 37.17%(491),which only virus positive rate of 21.27%(281).Bacterial positive rate was 25.28%(334),which only bacteria positive rate of 7.49%(99),Mycoplasma positive rate for 27.78%(367),including simple Mycoplasma positive rate of 12.04%(159).2.Bacterial pathogen mainly Streptococcus pneumoniae,follow Escherichia colinon,Fermentative gram-negative.virus pathogen mainly respiratory synthetic syncytial virus,follow Parainfluenza viruses Ⅲ.3.On the age distribution,total bacteria and virus detection rate were statistically significant,bacteria mainly detected in over 3 years of age age groups,the virus mainly under 1 year old age group checked out.4.0n the season distribution,respiratory syncytial virus and influenza a virus is mainly detected in winter;Adenovirus in July,the highest detection rate;Streptococcus pneumoniae detection mainly in November;E.coli mainly in July and August.5.Mycoplasma pneumoniae detection rate differences in age and season all have statistical significance,1 year old of age detection rate lowest;Mycoplasma pneumoniae detection mainly in spring and winter.Conclusion1.Community-acquired pneumonia pathogen in children with viral pathogen is given priority to,and given priority to with respiratory syncytial virus,mainly popular in winter;Bacteria are mainly composed of streptococcus pneumoniae,popular in fall and winter;Mycoplasma pneumoniae mainly popular in spring and winter.2.Children under the age of 1 original mainly for virus pathogenic community for sexually transmitted diseases,more than 3 years old mainly for bacteria pathogenic and Mycoplasma pneumoniae.
