Key Points
• Aspirin-exacerbated respiratory disease (AERD) consists of the triad of asthma,
chronic rhinosinusitis with nasal polyposis, and respiratory reactions to COX-1 inhibitors/allergy to nonsteroidal anti-inammatory drugs.
• Aspirin desensitization in patients with AERD is an effective means to control
inammatory symptoms.
• Aspirin therapy after desensitization improves sinus and respiratory symptoms,
reduces polyp formation, and reduces the need for oral and inhaled corticoste­roids and revision sinus surgery.
• Aspirin therapy is affordable and cost-effective as rst-line therapy after com-
plete endoscopic sinus surgery.

inammatory syndrome characterized by the combination of asthma, chronic rhino­sinusitis with nasal polyposis (CRSwNP), and acute respiratory reactions following exposure to cyclooxygenase (COX)-1 inhibitors. Table23.1 lists the medications that are known to inhibit COX-1 and COX-2 enzymes. In AERD patients, chal­lenges with highly selective COX-2 inhibitors have demonstrated that these medica­tions are well tolerated [1]. There is variable cross-reactivity among the weakly selective COX-1 inhibitors, and these reactions tend to be less severe. Settipane demonstrated 34% cross-reactivity in AERD patients with acetaminophen doses at or above 1000mg [2]. Lower doses did not seem to trigger respiratory reactions.
AERD is often rst noted following an upper respiratory infection in early adult­hood, with progression to chronic rhinosinusitis and recurrent nasal polyposis. As the sinus disease develops, lower respiratory tract symptoms also begin, and asthma is diagnosed. In some cases, respiratory symptoms are more notable, and asthma may be diagnosed before nasal polyposis. Respiratory sensitivity to COX-1­inhibiting NSAIDs often manifests after the establishment of upper and lower respi­ratory disease. The syndrome can take 2–4years to clinically manifest its full triad, thereby leading to diagnostic confusion and delays [3]. Rarely, a patient with AERD does not demonstrate clinical asthma, the so-called upper airway variant. When patients with AERD ingest aspirin or an NSAID, they develop acute upper and/or lower respiratory symptoms. Other clinical associations include anosmia or hypos­mia, respiratory reactions to alcoholic beverages especially beer and wine, atopic disorders, and peripheral blood eosinophilia. AERD affects between 7% and 15% of patients with asthma and up to 16% of patients with CRSwNP [4, 5]. Atopy is pres­ent in a higher-than-expected number of AERD patients; however, the clinical sig­nicance of this nding is still unclear [6]. Exposure to passive cigarette smoke in early life and a personal history of smoking have been associated with more than a threefold increase in the odds of developing AERD [7]. Atopy, cigarette smoke, and

viral or bacterial insults to the sinonasal epithelium could be initial catalysts in igniting the dysregulated inammation seen in AERD.Unfortunately, despite an avalanche of recent publications, AERD is often underdiagnosed due to a lack of physician recognition [8].
Pathophysiology
Arachidonic acid metabolism is chronically dysregulated in AERD (Fig. 23.1). There is overproduction of cysteinyl leukotrienes (LTC4, LTD4, LTE4) and PGD2, which leads to the development of bronchospasm, increased mucus production, increased vascular permeability, and recruitment of inammatory cells [911]. Levels of PGE2, which has anti-inammatory effects and suppresses leukotriene production, are reduced in AERD [11]. Abnormal aggregates of platelets and leuko­cytes (i.e., neutrophils, eosinophils, and monocytes) can share metabolic processes (i.e., through transcellular transfer of metabolic intermediates) to produce high amounts of inammatory leukotrienes [12]. Eosinophils and mast cells have been

shown to be primary sources of excess leukotrienes in patients with AERD [1315]. Basophils have also been demonstrated to contribute to AERD pathogenesis, although their involvement in AERD pathophysiology remains unclear [16]. Recently, it has been demonstrated that there may be inammatory heterogeneity within AERD, which can be differentiated into three inammatory sub-endotypes: (1) low inammatory burden, (2) very high type 2 cytokines (IL-4, IL-5, IL-13), and (3) low type 2 cytokines with high levels of type 1 (IFN-γ) and type 3 cytokines (IL-17A). The concept of sub-endotypes within AERD may explain some of the differential responses to treatments.

Radiographic andHistologic Findings
CT imaging of the sinuses reveals pan-sinus opacication in most AERD patients secondary to diffuse mucosal inammation [6]. Bony thickening of the intersinus septum and sphenoid bone is also seen in increased frequency [17]. The evolution of sinus polypoid opacication typically starts in the ethmoid and frontal sinuses [18]. Normal preoperative imaging of the sinuses rules out the diagnosis of AERD.Histologically, AERD is characterized by increased inammation within the upper and lower respiratory tracts. Bronchial and nasal/sinus tissue examination reveals an increased number of eosinophils and degranulated mast cells [13, 19].
Diagnosis
A clinical diagnosis of AERD can be made based on a history of asthma and nasal polyposis, in addition to adverse reactions caused by aspirin, NSAIDs, or other COX-1 inhibitors. Many patients do not have a clear history of adverse reactions to COX-1 inhibitors or other NSAIDs. In patients without a clear history, aspirin chal­lenge can conrm or exclude hypersensitivity and is considered the gold standard for diagnosing AERD [20]. Urinary leukotriene E4 measurements are poorly pre­dictive of AERD [21]. Diagnostic aspirin challenges should be offered to patients with suspected AERD prior to endoscopic sinus surgery to increase diagnostic accu­racy and to minimize the risk of false-negative aspirin challenges, which are some­times seen in the early postoperative period [22].

Aspirin Challenge

Indications forAspirin Challenge
An aspirin challenge should be considered in all chronic rhinosinusitis with nasal polyposis patients with an unclear clinical presentation. A list of clinical scenarios where an aspirin challenge should be considered is shown in Table23.2.

Indications for aspirin challenge
A common clinical scenario that would warrant an aspirin challenge includes patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) and asthma without a previous exposure to aspirin or COX-1 inhibitor during the time of the inammatory disease. Leukotriene receptor antagonists can modify upper airway symptoms in AERD and can decrease nasal symptoms with aspirin exposure, which can potentially mask an underlying hypersensitivity. Therefore, an aspirin challenge can be considered in patients with CRSwNP and asthma who have tolerated aspirin or COX-1 inhibitors while receiving concomitant leukotriene or 5-lipoxygenase inhibitor treatment [23]. There is also a subset of patients who are desensitized to aspirin through low-dose daily use; these patients would also benet from an aspirin challenge after holding their daily aspirin for 10days [24]. An aspirin challenge may also be considered in patients who are poor perceivers of symptoms, patients with suggestive radiographic or histopathologic ndings, and patients with refrac­tory sinus disease. It is possible to have AERD without asthma; therefore, aspirin challenge can be considered in carefully selected patients with a history of chronic pansinusitis alone.
A study by Dursun etal. evaluated 243 consecutive referrals for aspirin chal­lenges and desensitization. They found that patients with at least two prior aspirin­and NSAID-associated respiratory reactions had an 89% chance of having a positive oral aspirin challenge [25]. Therefore, aspirin challenge is typically unnecessary in patients with CRSwNP and asthma who report a history of two previous hypersen­sitivity reactions to aspirin or COX-1 inhibitors. In this same study, patients who had one serious respiratory reaction associated with aspirin/NSAID ingestion had a 100% likelihood of a positive challenge, thereby eliminating the need to challenge patients with this history.
