AbstractWheezing disorders are very common in preschool children and most of these episodes are related to viral infections. The majority children with asthma would present with symptoms in the first few years of life. Most children with wheezing in the first few years will not develop asthma in the childhood years. Although there have been many regional or international guidelines for the treatment of asthma, most of them are primarily related to older children and adults, recent studies have documented that there are different phenotypes of wheezing disorders in the preschool years and several organizations have attempted to produce consensus guidelines for wheezing disorders in this age groups. The difficulties have been the lack of clear definition of diagnosis, the absence of affordable and reliable investigations in the preschool age as well as the lack of effective medications. The use of ICS will not change the natural history of those who are at high risk of subsequent development of asthma. Viral infections such as human Rhinovirus infections and RSV are the most common precipitant of wheezing attacks in young children. Systemic steroid has not been found to be effective in the management of acute attacks. Daily or as needed use of ICS are have not been found to be effective in reducing future risk of wheezy attacks unless the patients are positive for the Asthma Prediction Index (PEAK trial). Further studies are needed to clearly identify the best treatment options for patients with different wheezing phenotypes. For now, the best treatment is close follow up to observe the natural history as the majority will outgrow the problem. Judicious use of ICS in those with from atopic families or personal atopic history may be warranted.
