Actual (reported)This study aims at determining the patterns of asthma remission, the prevalence of these different patterns, the various factors associated with such remissions and possible recurrences of asthma, in order to determine the mechanisms involved in these processes. The investigators therefore want to document these specificities in subjects in complete remission of their asthma, and those in only symptomatic remission of their asthma, in comparison with mildly symptomatic asthmatic subjects and healthy controls.
