Abstract

Nonsteroidal anti-inflammatory drugs (NSAID)-exacerbated respiratory disease (NERD) is defined by intolerance to cyclooxygenase 1 inhibitors, chronic rhinosinusitis with recurrent nasal polyps, and/or intrinsic bronchial asthma. Long-term administration of acetylsalicylic acid (ASA) after desensitization has been used to mitigate these sequelae, but the optimal dose and balancing symptom relief and side effects remain unsettled. Retrospective data analysis of 85 patients with NERD receiving maintenance therapy of 300 mg ASA was followed by questionnaires (our own, not validated and the Sino-Nasal Outcome Test-20). We received responses from 55 patients and examined 30 of them clinically. Patients with no ASA-associated side effects were 56.4% (56 of 85 patients) of the cohort. In this study, 60% (33 of 55 patients) continued prophylaxis of 300 mg ASA daily for an average of 34.7 months. Elective surgery was the most frequent cause of discontinuation of ASA (21.8%; 12 of 55 patients). Rhinomanometry values were significantly improved with ASA (P < .05; Wilcoxon), but there was no significant reduction in nasal polyposis or improvement in olfaction at the time of follow-up examination. Minor clinical improvements were identified. Side effects were well tolerated by most patients, and no serious sequelae occurred. The indications for long-term ASA therapy in NERD patients remain unsettled.
