All are true about aspirin sensitive asthma excpet –
## **Core Concept**
Aspirin-sensitive asthma, also known as aspirin-exacerbated respiratory disease (AERD), is a condition where patients have chronic rhinosinusitis, asthma, and sensitivity to aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs). This condition is associated with an abnormal metabolism of arachidonic acid.
## **Why the Correct Answer is Right**
In AERD, the inhibition of cyclooxygenase-1 (COX-1) by aspirin and other NSAIDs leads to a shift in the metabolism of arachidonic acid towards the production of cysteinyl leukotrienes, which are potent bronchoconstrictors and pro-inflammatory mediators. This results in bronchoconstriction, rhinitis, and other respiratory symptoms. The correct answer involves understanding the pathophysiological mechanism of AERD.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is not provided, but typically, correct statements about AERD might include its association with chronic rhinosinusitis, asthma, and the role of COX-1 inhibition.
- **Option B:** Similarly, without the content, we assume this could relate to the pathophysiology or clinical presentation of AERD, such as the involvement of cysteinyl leukotrienes.
- **Option C:** This might relate to the management or characteristics of AERD, such as the use of leukotriene modifiers as part of the treatment.
- **Option D:** The statement in option seems to be missing; however, given that is marked as the correct answer, we infer that provides an incorrect statement about AERD.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that patients with AERD often have a triad of asthma, chronic rhinosinusitis with nasal polyps, and sensitivity to aspirin/NSAIDs. The use of leukotriene-modifying agents can be beneficial in managing this condition.
## **Correct Answer: D.**
