title: Clinical management of severe therapy-resistant asthma.
abstract: Severe therapy-resistant asthma is an area where there has been recent advances in understanding that is percolating into improvements in management. Areas covered: This review covers the recent definition and approach to the diagnosis of severe asthma and its differentiation from difficult-to-treat asthma. The recent advances in phenotyping severe asthma and in ensuing changes in management approaches together with the introduction of new therapies are covered from a review of the recent literature. Expert commentary: After ascertaining the diagnosis of severe asthma, patients need to be treated adequately with existing therapies. The management approach to severe asthma now comprises of a phenotyping step for the definition of either an allergic or eosinophilic severe asthma for which targeted therapies are currently available. This will lead to a precision medicine approach to the management of severe asthma.
