Bronchoscopy With Bronchial Biopsies Sub-study of: Persistence of Airway Inflammation and Remodeling in Asthma Remission
NCT00526344 · Status: WITHDRAWN · Type: OBSERVATIONAL · Enrollment: 36
Last updated 2011-02-14
Summary
This study aims at determining the patterns of asthma remission, the prevalence of these different patterns and the various factors associated with such remissions and possible recurrences of asthma, in order to determine the mechanisms involved in these processes.
We therefore want to document these specificities in studying biopsies of 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.
