[Cough from an allergological as well as from the ENT aspect].

Cough from an allergological as well as from the ENT aspect Cough is a common problem in the allergological, but less so in the rhinological consultation. The differential diagnostic spectrum for cough is extensive and may range from rhinitis and asthma to eosinophilic esophagitis and rarer diseases. In the case of chronic cough (> 2 months), the four most frequent causes must be sought, or be excluded (upper airway cough syndrome, asthma [cough-variant-asthma], non-asthmatic eosinophilic bronchitis, gastroesophageal reflux disease). Aeroallergens such as pollen, house-dust mites or occupational substances play a major role in allergies. Nevertheless, it is not uncommon for cough to be a main symptom of an antibody deficiency or a Sicca symptom complex. The more chronic the cough, the more thoroughly an investigation is indicated - often interdisciplinary. Therapy depends on the cause of the cough. In allergic respiratory diseases, allergy-specific immunotherapy may be indicated.
