The inability to accurately predict the outcome of infants with recurrent wheezy bronchitis makes the early use of inhaled corticosteroids (ICS) controversial. Data from bronchoalveolar lavages and epidemiological surveys suggest a persistent inflammation of the airways in the more severe cases. Prospective studies, mostly with nebulized corticosteroids, have demonstrated clinical ...

Infants who wheeze are likely to have narrowed or overly compliant airways rather than atopy. After around 3 years of age, airway responsiveness and atopy are associated with the development of wheeze and the diagnosis of asthma. Anti- or proinflammatory genes are likely to be responsible for at least part ...
Fahy J V - - 2000
An important advance in our understanding of the pathophysiology of asthma has been the discovery that airway inflammation is not confined to severe asthma but also characterizes mild and moderate asthma. Inflammation in asthma may be the result of a peculiar type of lymphocytic inflammation whereby Th2 lymphocytes secrete cytokines ...
