ABSTRACT

Objective:To explore the relationship between viral respiratory tract,mycoplasmal pneumonia,Chlamydia pneumonia infection and actue attack of asthma in children.Methods:7 viruses including respiratory syncytial virus(RSV),adenovirus(Adv),influenza virus A(InfA),influenza virusB(InfB),and parainfluenza virus 1.2.3(PInfl.2.3) from the nasopharyngeal aspirate of the patients were rapidly diagnosed by immunofluorescence method and MP.CP-IgM in serum were detected with ELISA.Results:18 cases could reach the definite etiological diagnosis among 45 infant asthmatic patients (40%).Of them RSV was discovered in 13 cases (accounting for 28.9%),ranking the first,second CP in 3 cases (6.7%),MP in 1 case (2.2%) and Plnf3 in 1 case (2.2%).13 cases (35.1%) were detected positively in 37 asthmatic patients of children.Of them MP was discovered in 9 cases (24.3%),ranking the first,second RSV in 4 cases (10.8%).Conclusion:The results indicate that infant asthma exacerbation is related closely to RSV and CP infections,but in children acute asthma exacerbation is related closely to MP infection.
