Approche diagnostique et thérapeutique d’un asthme difficile [Diagnostic and therapeutic approach to difficult asthma]

Asthma is a chronic disease and asthma control can be affected by many factors. In case of difficult asthma, intensifying drug therapy is not the key. This type of asthma needs an overall management in order to diagnose and treat each factor known to be associated with poor asthma control. The aim of this article is to describe the structured and systematic approach for these patients.
