Investigation of the Relationship between Aspirin-Sensitivity and Poor Response to Medical Management in NSAIDs-exacerbated Respiratory Disease Patients with Sinonasal Polyposis.
BACKGROUND: NSAID-exacerbated respiratory disease (N-ERD) is a highly heterogeneous disorder with various clinical symptoms. The aspirin challenge test is a gold standard method for its diagnosis, and there are still no reliable in vitro diagnostic biomarkers yet. Oral challenge tests are time-consuming and may be associated with a risk of severe systemic reactions. This study aimed to evaluate whether patients with poor responses to medical management are more susceptible to being aspirin-sensitive.
METHODS: In this cohort study, after CT scanning of all patients and subject selection, conventional medical treatment was started as follows and continued for three consecutive months: at first, saline nose wash twice per day, intranasal beclomethasone spray one puff in each nostril twice per day, montelukast 10 mg tablet once daily, a ten-day course of oral prednisolone starting with the dose of 25 mg per day and taper and discontinued thereafter. Sinonasal outcome test 22 (SNOT22) was used for the evaluation of symptom severity. Statistical analyses were performed with SPSS version 23, and data were analyzed using an independent samples T-test, paired T-test, and Receiver operating curve analysis.
RESULTS: 25 males and 53 females were enrolled in this study, with an average age of 41.56 ± 11.74 years old (18-36). Aspirin challenge test results were positive in 29 (37.2%) patients. The average SNOT22 scores before the treatment were 52.97 ± 17.73 and 47.04 ± 18.30 in aspirin-sensitive and aspirin-tolerant patients, respectively, and decreased to 27.41 ± 16.61 and 24.88 ± 16.72 in aspirin-sensitive and aspirin-tolerant patients after the treatment, respectively. There was no significant difference in SNOT22 scores between the groups.
CONCLUSION: The severity of symptoms before treatment and clinical improvement after treatment are not good predictors of N-ERD.
