[ASA-intolerance syndrome and persistent rhinosinusitis : Differential diagnosis and treatment].
BACKGROUND
A differential diagnosis of persistent chronic rhinosinusitis is ASA-intolerance syndrome (AIS), also known as Aspirin®‑exacerbated respiratory disease (AERD), Samter-Trias (Samter's disease, Morbus Widal). Particularly in cases of frequent recurrency of nasal polyps in combination with bronchial asthma and hypersensitivity reactions to acetylsalicylic acid (ASA) and other nonsteroidal anti-inflammatory drugs (NSAR) can often be referred to an underlying AIS. The pathogenesis of this syndrome is attributed to a misallocation of the arachidonic acid metabolism, resulting in an increased leukotriene production.


METHODS
The diagnosis may be difficult in the early stages of the disease with incomplete triad of symptoms.


RESULTS
Therapy may consist of paranasal sinuses surgery, drug therapy and adaptive deactivation as the only causal treatment option for patients with AIS.


CONCLUSIONS
For adaptive desactivation, positive effects were actually shown even in patients with long-term recurrent or persistent complaints of chronic rhinosinusitis.
