Abstract

|
The natural history of asthma is quite variable, not easy to predict. Infant may have complete remission of wheezing while growing up, but the chance decreases, if the wheezing develop or persist after age of six years or the child had positive skin test. Familial history is suggested consistently as the risk factor of wheezing and asthma. In adolescent, remission is also possible, and in fact, 50∼60% of asthmatics can have remission. However, the remission rate was only 15% in severe asthma, and sensitization to allergen also decreases the possibility. In the long term, lung function of asthmatics is lower than healthy people. In relevant to this, asthma is the risk factor of chronic obstructive pulmonary disease (COPD).
