Recent studies suggest that some particular viral infection and/or bacterial infection/colonization exacerbates wheezy condition across all age groups in children.
In this study we examine the association between viral infection and/or bactrerial colonization in nasopharyngeal secretions in patients who experience at least one wheezing episode confirmed by pediatrician, then,
evaluate the suitable way for management of wheezing condition(i.e. the efficacy of leukotriene receptor antagonist, inhaled corticosteroids, and antibiotics)
Efficacy
the results of viral isolation and bacterial culture in nasopharyngeal secretions
Severity of wheezing episodes (need for hospitalization)
The points of Childhood asthma control test,
The points of Japanese Pediatric Asthma Control Program,
length of hospital stay,
length of oxygen requirement,
lowest oxygen saturation,
incidence of systemic administration of corticosteroids,
the result of blood test

Respiratory syncytial virus is detected in patients with no history of wheezing.
Other viruses such as human rhinoviruses,human metapneumoviruses, human bocaviruses, and human parainfluenza viruses are dominant in patients with such history.
The patients who require hospitalization are colonized with Moraxella catarrhalis as well as Haemophilus influenza and Streptococcus pneumonia.
The patients with bacterial colonization in nasal cavity tend to experience exacerbation of wheezy episode.
Bacterial colonization in nasopharynx contributes to exacerbation of wheezing episode.
Haemophilus influenza and Streptococcus pneumonia are frequently detected during wheezing episode.
The coexistence of viral infection and the bacterial infection/colonization increases the severity of wheezy condition.
Leukotriene receptor antagonists inhibit repetition of wheezing episodes.
Inhaled corticosteroids inhibit exacerbation of wheezing episodes in children over the age of 5 years old.
