To determine whether an electronic health record (EHR) system can be used to identify cases of aspirin-exacerbated respiratory disease (AERD) in an area outside of a regional referral center with low rates of aspirin desensitization therapy.
Retrospective chart review single academic tertiary care hospital.
Single-site academic tertiary care hospital.
Using Epic\'s SlicerDicer function, an algorithm was created and applied to all patient charts from 2013 to 2021. The algorithm was as follows: \"Allergy/Contraindication to NSAIDs OR aspirin\" AND \"Diagnosis of Nasal polyp AND \"Diagnosis of Asthma.\" Clinical data including demographics, NSAID reaction, and specialist involvement was collected.
A total of 54 potential cases of AERD were identified. Thirty-two were determined to have AERD after chart review, yet 12 of these patients (37.5%) had no mention of AERD within the chart. The 54 patients were stratified into 2 cohorts based on reaction to NSAIDs: respiratory (n = 29) or unspecified (n = 25). Of the patients in the respiratory reaction group, 26 were found to have clinical AERD, demonstrating a positive predictive values (PPV) of 89.7%. The overall PPV was 59.3%. Those with a respiratory reaction to NSAIDS listed in the EHR were more likely to have clinical AERD (odds ratio 27.44; confidence interval 6.08-123.85; p < 0.0001). Only 2 patients (6.3%) underwent aspirin desensitization.
AERD remains under-diagnosed in the study population. The informatics algorithm presented here has a high positive predictive value for identifying clinical AERD patients in a geographical area with low rates of aspirin desensitization and may aid in identifying candidates for expanded treatment options.

Aspirin-exacerbated respiratory disease (AERD) is characterized by abnormal arachidonic acid metabolism leading to chronic rhinosinusitis with nasal polyposis (CRSwNP), asthma, and upper and/or lower respiratory symptoms after ingestion of cyclooxygenase-1 inhibiting nonsteroidal antiinflammatory drugs. Diagnosis is clinical and may involve an aspirin challenge. Inflammatory biomarkers may be useful for diagnosis and treatment monitoring. Conventional medical management for asthma and CRSwNP is often inadequate. Endoscopic sinus surgery followed by continued medical management with or without aspirin desensitization frequently improves symptoms and objective disease measures. Biological agents targeting eosinophilic inflammation are promising alternatives to conventional management.

Samter\'s triad, also known as aspirin-exacerbated respiratory disease, is characterized by nasal polyposis, bronchial asthma, and aspirin intolerance. Here, we present a case of a 36-year-old woman with a history of Samter\'s triad and recurrent dacryocystitis. After combined dacryocystorhinostomy and endoscopic sinus surgery, pathological specimens of the lacrimal sac showed respiratory fibrosis with chronic inflammation and eosinophilic infiltration. Our case demonstrates that Samter\'s triad is a potential etiology for inflammatory nasolacrimal duct obstruction.

Nonsteroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (N-ERD) has been considered an acquired condition. Positive first-degree family history has been reported in 1% of cases. The geographic and genetic isolation of the Finnish population offers exceptional opportunities for inheritance studies. In this questionnaire study, we explored the familial aggregation of N-ERD in 66 Finnish families of patients with N-ERD. The majority of patients (67%) had a positive family history of NSAID intolerance, asthma, nasal polyposis, or N-ERD. Furthermore, 55% had a positive first-degree family history of asthma, 21% nasal polyposis, 20% NSAID intolerance, and 11% N-ERD. The prevalence of asthma, nasal polyposis, NSAID intolerance, and N-ERD among first-degree relatives was 13%, 5%, 4%, and 2%, respectively. We present the pedigrees of the 44 affected families. According to our findings, Finnish patients with N-ERD seem to have a genetic susceptibility to it.

The pathomechanisms behind NSAID-exacerbated respiratory disease are complex and still largely unknown. They are presumed to involve genetic predisposition and environmental triggers that lead to dysregulation of fatty acid and lipid metabolism, altered cellular interactions involving transmetabolism, and continuous and chronic inflammation in the respiratory track. Here, we go through the recent advances on the topic and sum up the current understanding of the background of this illness that broadly effects the patients\' lives.

Patients with aspirin exacerbated respiratory disease (AERD) experience a severe and recalcitrant form of chronic rhinosinusitis with nasal polyposis (CRSwNP) and asthma, which are exacerbated by aspirin/NSAID ingestion. As compared with aspirin-tolerant CRSwNP, patients with AERD experience more severe olfactory dysfunction, which is one of the key contributors to the observed decrease in quality of life (QOL) in this disease. The objective of this paper is to review the published olfactory outcomes observed with various treatment modalities.

UNASSIGNED: Aspirin-exacerbated respiratory disease (AERD) is a difficult-to-treat syndrome where timely diagnosis and initiation of disease-specific therapies are pertinent to improved patient outcomes.
UNASSIGNED: To characterize the most common timeline for development of the clinical triad [asthma, nasal polyposis, and reactions to nonsteroidal anti-inflammatory drugs (NSAIDs)], identify barriers to prompt diagnosis of AERD, and describe indications for an aspirin challenge to facilitate accurate diagnosis.
UNASSIGNED: Six hundred ninety-seven patients with diagnosed AERD and history of at least one sinus surgery to remove nasal polyps were identified in the Brigham and Women\'s Hospital AERD registry. Patient reported age at disease onset of asthma, nasal polyposis, and age of first NSAID reaction were obtained from 2013 to 2019 at enrollment.
UNASSIGNED: Of the 697 patients identified, diagnosis of asthma preceded diagnosis of nasal polyposis and first NSAID reaction, although there was considerable variability between patients.
UNASSIGNED: Prompt diagnosis of AERD is important for patient and provider education and improved care of this difficult-to-treat population of patients. Consider diagnostic aspirin challenge in patients without historical reactions to NSAIDs who have an otherwise compatible clinical history, specifically in patients who take daily low-dose aspirin, leukotriene modifiers, avoid NSAIDs, or who are severely symptomatic at baseline where it would be difficult to identify an acute worsening of symptoms.

It is well-established that following ingestion of aspirin or any other inhibitor of cyclooxygenase-1, patients with Samter\'s disease, or aspirin-exacerbated respiratory disease (AERD) develop the sudden onset of worsening respiratory clinical symptoms, which usually involves nasal congestion, rhinorrhea, wheezing and bronchospasm. Gastrointestinal distress, nausea, a pruritic rash and angioedema can also occasionally develop. However, the underlying pathologic mechanism that drives these clinical reactions remains elusive. Pretreatment with medications that inhibit the leukotriene pathway decreases the severity of clinical reactions, which points to the involvement of cysteinyl leukotrienes (cysLTs) in the pathogenesis of these aspirin-induced reactions. Furthermore, studies of aspirin challenges in carefully-phenotyped patients with AERD have confirmed that both proinflammatory lipid mediators, predominantly cysLTs and prostaglandin (PG) D2, and the influx of effector cells to the respiratory tissue, contribute to symptom development during aspirin-induced reactions. Mast cells, which have been identified as the major cellular source of cysLTs and PGD2, are likely to be major participants in the acute reactions, and are an attractive target for future pharmacotherapies in AERD. Although several recent studies support the role of platelets as inflammatory effector cells and as a source of cysLT overproduction in AERD, it is not yet clear whether platelet activation plays a direct role in the development of the aspirin-induced reactions. To further our understanding of the pathogenesis of aspirin-induced reactions in AERD, and to broaden the pharmacotherapeutic options available to these patients, additional investigations with targeted clinical trials will be required.

The high levels of eicosanoid production and the clinical efficacy of leukotriene-modifying pharmacotherapies for patients with aspirin-exacerbated respiratory disease (AERD) suggest that other interventions targeting arachidonic acid dysregulation may also improve disease control.
To assess the utility of a high omega-3/low omega-6 diet for the treatment of AERD.
Prospective, nonblinded dietary intervention in 10 adult patients with AERD at Brigham and Women\'s Hospital in Boston, MA. The primary objective was for subjects to reduce dietary omega-6 fatty acid consumption to less than 4 g/d and increase omega-3 intake to more than 3 g/d. The primary outcome was change in urinary leukotriene E4, with changes in other eicosanoids, platelet activation, lung function, and patient-reported questionnaires also assessed.
Of the 10 subjects who screened for the study, all 10 completed the dietary intervention. Urinary leukotriene E4 decreased by 0.17 ng/mg (95% CI, -0.29 to -0.04; P = .02) and tetranor prostaglandin D-M decreased by 0.66 ng/mg creatinine (95% CI, -1.21 to -0.11; P = .02). There was a 15.1-point reduction in the 22-item Sino-Nasal Outcome Test score (95% CI, -24.3 to -6.0; P = .01), a 0.27-point reduction in the 7-item Asthma Control Questionnaire score (95% CI, -0.52 to -0.03; P = .03), and no change in FEV1 % predicted (P = .92) or forced vital capacity % predicted (P = .74). All patients lost some weight over the 2-week intervention period, and there were no diet-associated adverse events.
A high omega-3/low omega-6 diet may be an appropriate adjunct treatment option for patients with AERD.
