RESUMEN

BACKGROUND: Aspirin-exacerbated respiratory disease (AERD) is characterized by chronic eosinophilic rhinosinusitis, nasal polyps, asthma, and respiratory sensitivity to aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs). In addition to sensitivity to aspirin and NSAIDs, the majority of patients with AERD have been reported to have respiratory intolerance associated with the consumption of alcohol. METHODS: A multicenter prospective cohort study was performed. Patients with AERD confirmed by aspirin challenge were eligible to participate. Those who described themselves as able to tolerate alcohol consumption were excluded. Patients underwent aspirin desensitization following endoscopic sinus surgery. A questionnaire was distributed to patients before and after desensitization to determine pre-desensitization and post-desensitization symptoms associated with alcohol ingestion. RESULTS: Forty-five patients were enrolled and 37 patients completed the study. The most common pre-desensitization symptoms were nasal congestion (95.6%), rhinorrhea (46.7%), and wheezing (40%). Improvement in the ability to tolerate alcohol was noted in 86.5% of participants (95% confidence interval [CI], 75.5% to 97.5%) and 70.3% of participants (95% CI, 55.5% to 85.0%) described desensitization to be "very helpful" or "extremely helpful" for their ability to tolerate alcohol. CONCLUSION: The majority of patients with AERD who experience respiratory symptoms with alcohol consumption describe improvement in this domain following aspirin desensitization.

RESUMEN

Background Aspirin-exacerbated respiratory disease (AERD), also known as Samter's triad or aspirin (ASA)-intolerant asthma, affects 7% of asthmatics and has a higher prevalence in those with chronic rhinosinusitis and concomitant nasal polyposis. ASA desensitization with daily ASA therapy is a uniquely beneficial treatment for this disease entity and has been shown to have a significant impact on symptom scores, polyp disease, and need for systemic corticosteroids. However, no long-term studies have demonstrated whether or not ASA therapy remains safe and beneficial for these patients beyond 5-10 years. Objective This study was designed to determine the clinical course of AERD patients desensitized between 1995 and 2010. Methods A 20-question survey was distributed to patients who successfully completed ASA desensitization between January 1995 and April 2010. The questions were designed to assess ASA safety and longitudinal effects of ASA therapy in AERD. Results Of the 285 patients contacted, 92 (32%) completed the questionnaire. Average length of follow-up was 15 years. Of survey responders, 35 patients had discontinued ASA therapy. Although adverse reactions occurred, many also discontinued due to lack of efficacy or need for surgery. For those remaining on ASA (62%), significant improvement in sense of smell, asthma, sinus, and allergic rhinitis scores were noted ( P ≤ .001). The majority of ASA patients (68%) had a positive response to treatment and did not require further sinus surgery. However, ASA therapy did not delay the time to next sinus/polyp surgery ( P = .27) or reduce total number of sinus surgeries ( P = .56) compared to those who stopped treatment. Nearly 85% of AERD patients on ASA therapy found it to be helpful in improving airway disease and quality of life. Conclusion Aspirin desensitization followed by daily maintenance ASA therapy appears to be safe and effective even after 10+ years of continuous use.

RESUMEN

BACKGROUND: Aspirin desensitization is an effective treatment option for aspirin-exacerbated respiratory disease. Aspirin desensitization protocol modifications have improved the safety and efficiency of this procedure, yet some providers remain reluctant to perform it. OBJECTIVE: The primary objective of this study was to evaluate the safety and outcomes of outpatient aspirin desensitization procedures. A secondary objective was to assess clinical characteristics that might predict reaction severity during aspirin desensitization. METHODS: Two hundred seventy-five patients underwent aspirin desensitization at Scripps Clinic between January 2009 and August 2015. Baseline patient characteristics and reaction results were analyzed in the 167 patients who reacted during desensitization. RESULTS: All of the 167 reactors, including 23 who were classified as severe reactors, were successfully desensitized in the outpatient setting. The average desensitization duration among reactors was 1.67 days, and the average duration for gastrointestinal reactors was 2.29 days. The mean baseline Sino-Nasal Outcome Test score was higher in severe reactors compared with nonsevere reactors (P = .05). Overall, patients receiving omalizumab had a similar reaction profile to those not receiving omalizumab. CONCLUSIONS: Most patients undergoing aspirin desensitization will have symptoms. It remains difficult to predict the severity of these symptoms. However, desensitization can be done safely and efficiently in an appropriately equipped outpatient setting. This treatment option should be made available to all patients with aspirin-exacerbated respiratory disease. The Sino-Nasal Outcome Test score might be able to predict more severe reactions and merits further study. Eight of the 9 patients receiving omalizumab reacted during desensitization, suggesting that it does not block reactions during aspirin desensitization.

RESUMEN

Aspirin-exacerbated respiratory disease (AERD) is characterized by chronic rhinosinusitis with nasal polyps, asthma, and reactions to cyclooxygenase-1-inhibiting drugs. This condition is often refractory to standard medical treatments and results in aggressive nasal polyposis that often requires multiple sinus surgeries. Aspirin desensitization followed by daily aspirin therapy is an important treatment option, and its efficacy has been validated in multiple research studies. Aspirin desensitization is not without risk, but specific protocols and recommendations exist to mitigate the risk. Most patients with AERD can undergo aspirin desensitization in an outpatient setting under the supervision of an allergist.

RESUMEN

Aspirin-exacerbated respiratory disease is a clinical entity comprising chronic rhinosinusitis with nasal polyposis, asthma and intolerance to COX-1 inhibiting drugs. The pathogenesis is not completely understood at this point, but abnormal arachidonic acid metabolism is a key feature in this syndrome. The diagnosis is confirmed only by direct drug challenge. Aspirin desensitization followed by daily aspirin therapy is a useful treatment option in these patients. In this review article are discussed the important characteristics and treatment of aspirin-exacerbated respiratory disease.

RESUMEN

Aspirin-exacerbated respiratory disease (AERD) is a clinical condition which results in adverse upper and lower respiratory symptoms, particularly rhinitis, conjunctivitis, bronchospasm, and/or laryngospasm, following exposure to cyclooxygenase-1 (COX-1) inhibiting drugs, namely aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs). A provocative aspirin challenge is the gold standard for diagnosis of AERD. Aspirin desensitization and continuous aspirin therapy has been highly efficacious in those patients with suboptimal control of their disease on current available pharmacotherapy or those with other underlying conditions (i.e., cardiovascular disease) who may require frequent treatment with aspirin or NSAIDs. This review article focuses on aspirin desensitization and the management of patients with AERD with a particular emphasis on outcomes in those patients with chronic rhinosinusitis and nasal polyposis.
