Abstract
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.
