[A Difficult-to-Treat Asthma Bronchiale Is Not Necessarily a Severe Asthma]

A Difficult-to-Treat Asthma Bronchiale Is Not Necessarily a Severe Asthma Abstract. New biologicals offer the opportunity for treatment of 'difficult-to-treat' asthma. Before prescribing these medications, each 'difficult-to-treat' asthma bronchiale has to be checked for factors aggravating asthma control (e.g. insufficient inhalation technique and adherence, persistent allergen exposure) and asthma-related comorbidities (e.g. rhinosinusitis, gastro-esophageal reflux disease or obstructive sleep apnea) rendering the asthma 'controlled'. Asthma phenotyping s essential for the understanding of different treatment modalities.
