Abstract:
Objective To explore the relationship between asthma exacerbation and respiratory tract infections of viruses,Mycoplasma pneumoniae(MP),Chlamydia pneumoniae(CP)in children.Methods Seven viruses including respiratory syncytial virus(RSV),adenovirus(AdV),influenza virus A(IFVA),influenza virus B(IFVB) and parainfluenza virus Ⅰ,Ⅱ,Ⅲ(PFVⅠ,Ⅱ,Ⅲ) from the nasopharyngeal aspirate of 74 patients with asthma were rapidly diagnosed by direct immunofluorescence assay,as well as the serum MP-IgM,CP-IgM were detected by the granule agglutinating method and indirect solid-phase enzyme immunoassay(EIA),respectively.Results Pathogens were detected in 29 out of 74 cases(39.2%) with asthma exacerbation.Of whom 14 cases(43.8%) were in infant and another 15 cases(18.8%) were in preschool and school children.RSV was the leading pathogen in infant,it was discovered in 6 cases(accounting for 18.8%).The se-cond pathogen was PFVⅢ which was discovered in 4 cases(12.5%).MP,AdV and CP accounted for 6.25%,3.1%,3.1%,respectively.But in preschool and school children,MP was the most common pathogen which were discovered in 9 cases(21.4%),the following pathogen was CP which was discovered in 3 cases(7.1%),PFVⅢ and RSV only accounted for 4.8%,2.4%,respectively.There was significant differences statistically between two groups in viral respiratory tract and atypical-microorganism infections rate(Pa
