Aspirin-exacerbated respiratory disease (AERD) consists of chronic rhinosinusitis with nasal polyps (CRSwNP), asthma, and hypersensitivity to aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs). Asthma is associated with increased risk of atherosclerotic cardiovascular diseases (ASCVD). However, there is lack of data on association between AERD and ASCVD.
To investigate the relationship between AERD and subsequent risk of ASCVD.
An algorithm to find patients with AERD was generated and validated through chart review at our home institution. This algorithm was applied to a national insurance claims database to obtain data for a retrospective cohort study. Demographic and comorbidity data were obtained for propensity matching. Several methods of analysis were performed on the data.
A total of 571 patients met criteria for AERD; 3909 met criteria for asthma, CRSwNP, and no allergy to aspirin or NSAIDs (group 1); and 75,050 met criteria for asthma, CRS without nasal polyps, and no allergy to aspirin or NSAIDs (group 2). After covariate adjustment, AERD was significantly associated with ASCVD, including severe ASCVD, over groups 1 and 2 regardless of asthma severity.
Patients with AERD are at higher risk of ASCVD than patients with asthma and CRSwNP or CRS without nasal polyps, underscoring the need for early ASCVD screening and a consideration for aspirin desensitization or use of a nonaspirin antiplatelet agent in the setting of AERD and comorbid ASCVD.

Aspirin exacerbated respiratory disease (AERD) is a condition caused by increased bronchoconstriction in people with asthma after taking aspirin or another NSAID. Molecular analysis of the human genome has opened up new perspectives on human polymorphisms and disease. This study was conducted to identify the genetic factors that influence this disease due to its unknown genetic factors. We evaluated research studies, letters, comments, editorials, eBooks, and reviews. PubMed/MEDLINE, Web of Sciences, Cochrane Library, and Scopus were searched for information. We used the keywords polymorphisms, aspirin-exacerbated respiratory disease, asthma, allergy as search terms. This study included 38 studies. AERD complications were associated with polymorphisms in ALOX15, EP2, ADRB2, SLC6A12, CCR3, CRTH2, CysLTs, DPCR1, DPP10, FPR2, HSP70, IL8, IL1B, IL5RA, IL-13, IL17RA, ILVBL, TBXA2R, TLR3, HLA-DRB and HLA-DQ, HLA-DR7, HLA-DP. AERD was associated with heterogeneity in gene polymorphisms, making it difficult to pinpoint specific gene changes. Therefore, diagnosing and treating AERD may be facilitated by examining common variants involving the disease.

OBJECTIVE: Previous studies have suggested that patients with aspirin-exacerbated respiratory disease (AERD) have a high likelihood of alcohol intolerance. The purpose of this systematic review is to identify if there is sufficient evidence to confirm this correlation and the impact of medical therapy on subsequent alcohol tolerance.
METHODS: PubMed, EMBASE, SCOPUS, EBSCO, Google Scholar, Cochrane Library, and Grey literature. We also performed snowballing on the identified observational studies (OS) for additional data.
METHODS: A systematic review was conducted from 1968 to 2022 to identify those studies describing AERD symptomatology triggered by alcohol intake. The primary outcome was to analyze the current literature for the association between alcohol intolerance and AERD symptoms. The secondary outcome looked for improvement in alcohol tolerance after aspirin desensitization or biological therapy.
RESULTS: A total of 775 studies were identified and 40 abstracts were evaluated. From these, 5 studies met the inclusion criteria. Of the 5 manuscripts, there was 1 case-control, 2 cohort, and 2 cross-sectional studies. A total of 522 participants with AERD and a history of alcohol consumption were included, with 52.8% reporting at least 1 sinopulmonary exacerbation after alcohol intake. One of 3 studies noted improvement in alcohol tolerance after medical therapy with aspirin desensitization.
CONCLUSIONS: The current literature suggests that patients with AERD have a high risk of alcohol intolerance. Additionally, aspirin desensitization may improve alcohol tolerance in this patient population.

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.

BACKGROUND: The clinical approach to upper and lower respiratory diseases from a joint perspective, known as united airways disease (UAD), is challenging for health care professionals owing to a paucity of specific studies.
OBJECTIVE: This study reviews recent scientific evidence on the management of asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) from a UAD perspective.
METHODS: A systematic search of PubMed, Scopus, and Web of Science was conducted for 9 research questions, and studies published from January 2015 to July 2021 were included. Quality assessment was performed with the Critical Appraisal Skills Programme.
RESULTS: In total, 32 publications met the inclusion criteria. Control of type 2 inflammation in UAD (reported in 9 studies) was associated with biologic therapies, for which an impact on asthma, CRSwNP, and/or aspirin/nonsteroidal anti-inflammatory drug-exacerbated respiratory disease outcomes was described in 9 studies. However, there was a lack of scientific evidence on clinical and/or biochemical markers associated with response to biologics in patients with UAD. The benefit on corticosteroid reduction in patients receiving biologics was reported in 9 studies. Three publications reported a positive impact of surgery on asthma and/or CRSwNP outcomes, and the effect of biologics on reducing the need of surgery was consistent across 6 studies.
CONCLUSIONS: Our results underscore an overall scarcity of scientific evidence on the treatment strategies for these frequent coexisting entities from an UAD approach but also identify several research gaps and unmet needs that should be addressed to ensure optimal diagnosis, management, and follow-up of these patients.

Aspirin-exacerbated respiratory disease (AERD) represents an aggressive form of chronic rhinosinusitis with nasal polyposis that is notoriously challenging to treat. There is evidence to suggest desensitization to aspirin may improve symptomatology and disease control in these patients. The goal of our study was to critically appraise the literature on this topic and assess the effect of desensitization on sinonasal symptomatology.
We searched EMBASE, CINAHL, MEDLINE, and the Cochrane Library for relevant literature. Studies were included if they were observational studies or randomized, controlled trials, had n > 1, and were published in English or French. Studies were excluded if they were systematic reviews. We assessed study for quality and presence of common sources of bias.
Twenty-four studies met the inclusion criteria. In general, polyp size, polyp recurrence, nasal symptom scores, sense of smell, number of acute rhinosinusitis episodes, and systemic steroid use improved when patients were desensitized. The vast majority of studies recommend desensitization.
There is mounting evidence that aspirin desensitization is a valuable adjunct to treat sinonasal symptoms in the treatment of patients who have AERD.

OBJECTIVE: Samter\'s triad is the combination of asthma, aspirin sensitization, and nasal polyposis. Few data are available on the use of omalizumab in this disease. The study aimed to describe the impact of omalizumab on clinical and functional parameters and the quality of life of a series of patients with Samter\'s triad. Moreover, we aimed to provide a review of the literature on this topic.
METHODS: We retrospectively described four patients with Samter\'s triad undergoing omalizumab therapy. Clinical, functional, and immunological data of these patients were collected at baseline and follow-up.
RESULTS: Reduction of asthma exacerbations and salbutamol rescue therapy were observed in all patients after anti-IgE treatment together with an improvement in the quality of life. A significant improvement in FEV1, FVC, and FEF25-75 was observed. No major side-effects were observed. A total of 14 studies regarding omalizumab in aspirin-exacerbated respiratory diseases were included in the review, comprising 78 patients. All studies reported a good efficacy in improving asthma control; restoration of aspirin tolerance was repeatedly reported.
CONCLUSIONS: The results of our case series and review of the literature suggest that omalizumab effectively improves asthma control, lung function tests, and quality of life in patients with Samter\'s triad.

Aspirin desensitization is increasingly recommended for the treatment of aspirin-exacerbated respiratory disease (AERD). The objective of this study is to systematically review the efficacy and safety of aspirin desensitization in patients with AERD.
We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and World Health Organization (WHO) International Clinical Trials Registry Platform from inception to January 5, 2019. We included randomized trials and comparative observational studies in any language. Data extraction and risk of bias assessment were performed in duplicate independently.
Five randomized controlled trials (RCTs) enrolled 233 patients with AERD. Compared to placebo, aspirin desensitization (mean daily dose 800 mg) improved quality of life (risk ratio [RR] 2.00; 95% confidence interval [CI], 1.31 to 3.06; heterogeneity measure [I2 ] = 0%; risk difference [RD] +24%; 22-item Sino-Nasal Outcome Test [SNOT-22] scale [0 to 110, higher worse]; mean difference [MD] -10.27 [95% CI, -6.39 to -14.15]; moderate-certainty); and respiratory symptoms (RR 2.20 [95% CI, 1.55 to 2.73], I2 = 34%, RD +36%; American Academy of Otolaryngology (AAO) scale [0 to 20, higher worse]; MD -2.56 [95% CI,-1.12 to -3.92]; high-certainty). Aspirin desensitization increased adverse events severe enough to cause treatment discontinuation (major bleeding, gastritis, asthma exacerbation, or rash causing drug discontinuation, RR 4.39 [95% CI, 1.43 to 13.50], I2 = 0%, RD +11%, moderate-certainty), and gastritis (RR 3.84 [95% CI, 1.12 to 13.19], I2 = 0%, RD +9%, low-certainty). Findings were robust to sensitivity analyses. Two available observational studies were not informative because they lacked adjustment for confounders and/or contemporaneous controls.
In patients with AERD, moderate-certainty and high-certainty evidence shows that aspirin desensitization meaningfully reduces symptoms of rhinosinusitis and improves quality of life, but results in a significant increase in adverse events.

Aspirin-exacerbated respiratory disease comprises a series of signs and symptoms mainly involving the upper and lower posterior airway after the consumption of cyclooxygenase enzyme inhibitors. Adverse reactions that occur are not considered to be an allergy and are common to all non-steroidal anti-inflammatory drugs, and cross-reactivity between these agents is therefore common. The description of 3 clinical cases serves to review key aspects of this condition, such as epidemiology, pathophysiology, clinical manifestations, diagnosis and management. Adequate diagnosis and education on the use or elimination of all different NSAIDs is essential, as well as availability of different analgesic options, verified with challenge tests. Aspirin-exacerbated respiratory disease management includes surgical procedures for nasal polyp control, pharmacological treatment for asthma control and desensitization with aspirin in selected individuals.
La enfermedad respiratoria exacerbada por aspirina comprende un conjunto de signos y síntomas que involucran principalmente la vía aérea superior e inferior posterior al consumo de inhibidores de la enzima ciclooxigenasa. Las reacciones adversas que se presentan no se consideran una alergia y son comunes a todos los antiinflamatorios no esteroideos, por lo que la reactividad cruzada entre estos es común. La descripción de tres casos clínicos con diferentes situaciones sirve para revisar aspectos clave de la enfermedad como la epidemiologia, fisiopatología, manifestaciones clínicas, diagnóstico y manejo. El adecuado diagnóstico y educación en el uso o eliminación de los diferentes AINE es fundamental, al igual que la disposición de opciones analgésicas alternativas, comprobadas mediante pruebas de provocación. El manejo de la enfermedad respiratoria exacerbada por aspirina incluye procedimientos quirúrgicos para el control de los pólipos nasales, tratamiento farmacológico para el control del asma y desensibilización con aspirina en individuos seleccionados.
