Background: Nonsteroidal anti-inflammatory drug (NSAID) exacerbated respiratory disease (N-ERD) is a triad with asthma, chronic rhinosinusitis with nasal polyps, and NSAID intolerance. Uncontrolled N-ERD forms a major public health problem due to frequent and difficult-to-treat exacerbations and/or requiring putatively frequent endoscopic sinus surgeries (ESS). Our aim was to study factors affecting control of N-ERD.

Methods: Retrospective patient record data (patient characteristics, prior sinus surgeries, follow-up data in 2020) from 167 N-ERD patients undergoing consultation at three tertiary hospitals from 2001 to 2017 was used. Outcome measurements reflecting uncontrolled N-ERD were revision ESS, corticosteroids/biological therapy, and antibiotic courses during 2016-2020. Associations were analyzed by using nonparametric tests, Cox's proportional hazard, and binary logistic regression models.

Results: Nasal polyp eosinophilia increased the risk of revision surgery during the follow-up (adjusted hazard ratio [aHR] 3.21, confidence interval 1.23-8.38). Also baseline oral corticosteroids (OCS; HR, 1.73, 1.04-2.89) and baseline surgery without total ethmoidectomy increased the risk of revision ESS (HR, 2.17, 1.07-4.42) in unadjusted models. In addition, both baseline OCS (adjusted odds ratio [aOR] 2.78, 1.23-6.26) and a history of ≥4 previous ESS (aOR, 2.15, 0.98-4.70) were associated with the use of OCS/biological therapy during the follow-up, but not with high number of antibiotics.

Conclusions: Nasal polyp eosinophilia, baseline OCS, and a history of recurrent ESS predict uncontrolled N-ERD. These factors might be clinically useful in risk-estimation of uncontrolled disease and for organizing follow-ups. Prospective cohort studies with larger sample size are needed to further study the factors affecting the upper airway control of N-ERD.

High Discontinuation Rates of Peroral ASA Treatment for CRSwNP: A Real-World Multicenter Study of 171 N-ERD Patients.

Background: Nonsteroidal anti-inflammatory drug (NSAID) exacerbated respiratory disease (N-ERD) consists of chronic rhinosinusitis with nasal polyposis (CRSwNP), asthma, and NSAID intolerance. Acetylsalicylic acid treatment after desensitization (ATAD) is a treatment option for uncontrolled N-ERD.

Objective: To evaluate peroral ATAD's long-term effectiveness on CRSwNP disease control. Read More

Can nasal acetylsalicylic acid challenge predict the severity of non-steroidal anti-inflammatory drugs (NSAIDs)-exacerbated respiratory disease (N-ERD)?

Allergol Select 2020 23;4:135-143. Epub 2020 Dec 23.

CVK Department of Otorhinolaryngology, Head and Neck Surgery, Charité - Universitätsmedizin Berlin, Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Berlin.

Background: Non-steroidal anti-inflammatory drugs (NSAIDs)-exacerbated respiratory disease (N-ERD) complicates the clinical course of chronic rhinosinusitis with nasal polyps (CRSwNP) and severe asthma. We aimed to determine the detection rate of NERD in patients with CRSwNP, asthma, and history of NSAID intolerance using nasal challenge with acetylsalicylic acid (ASA) and the relationship between the severities of response to ASA challenges and the grade of N-ERD.

Materials And Methods: Three groups of patients were included: CRSwNP with asthma and clinical history of analgesics intolerance (CRSwNP-AAI n = 18), CRSwNP with asthma but without a clinical history of analgesics intolerance (CRSwNP-A n = 20), and CRSwNP without asthma or analgesics intolerance (n = 18).
