[Evaluation of association between an acute attack of childhood bronchial asthma and Chlamydia pneumoniae infection].
OBJECTIVE
To identify whether there is an association between an acute attack of childhood bronchial asthma and Chlamydia pneumoniae (CP) infection.


METHODS
Serum specific antibodies IgM and IgG to CP were detected by ELISA in 120 asthmatic children with an acute attack and 82 healthy children.


RESULTS
Anti-CP IgM was demonstrated in 22 cases (18.3%) and anti-CP IgG was demonstrated in 32 cases (26.7%) out of the 120 asthmatic patients. The incidence of CP infection in asthmatic children was significantly higher than that in healthy controls (3.7%) (P < 0.01). Glucocorticoid inhalation treatment alone resulted in a remission of an acute attack of asthma in 15 cases out of the 32 cases with CP infection, but 17 cases required glucocorticoid inhalation treatment together with anti-CP infection treatment (macrolide antibiotics, eg. azithromycin) for remission of asthma attack.


CONCLUSIONS
There may be a link between an acute attack of childhood asthma and CP infection. It is thus necessary to detect the CP-specific antibodies in asthmatic children for proper treatment.
