Non-steroidal anti-inflammatory drug exacerbated respiratory disease

Last revised by Joshua Yap on 31 Aug 2022

Non-steroidal anti-inflammatory drug (NSAID) exacerbated respiratory disease refers to the clinical constellation of 1,2:

Non-steroidal anti-inflammatory drug (NSAID) exacerbated respiratory disease is also known as Samter syndrome (or triad)Widal syndrome, aspirin-induced asthma, aspirin exacerbated respiratory disease (AERD), and analgesic-induced asthma.

In adults, prevalence ranges between 8-20% among those given an oral provocation test (OPT), and around 3-5% among patients who self-report that they have the triad 5.

Treatment is largely centered around avoiding aspirin, treating underlying asthma, and occasionally sinonasal polypectomy (surgical or medical). Unfortunately recurrence is common 2.  

Aspirin desensitization has also been tried with at least some short term improvement 2

The name Samter triad or syndrome was named after the American allergy physician Max Samter (1908-1998) 7 who was the first to comprehensively describe this clinical triad in 1968 6.
