Real-Life Experience of Biologic Treatment for Asthma on Chronic Rhinosinusitis: A Finnish Cohort.

INTRODUCTION: Biologics are used in the treatment of severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). The purpose of this retrospective study was to evaluate the effects of biologics initiated for asthma on coexistent CRS and the influence of comorbid factors, including aspirin-exacerbated respiratory disease (AERD) and secretory otitis media (SOM). METHODS: A review of electronic health records (2009-2020) at a Finnish tertiary center was conducted to identify CRS patients treated with biologics for their asthma. We identified the type of biologic and treatment response, by comparing nasal polyp score (NPS), sinonasal outcome test (SNOT)-22, need for oral corticosteroids (OCS) and antibiotics, frequency of visits, and endoscopic sinus surgeries (ESS) pretreatment and during treatment. RESULTS: 55 patients were treated with anti-immunoglobulin E (IgE) (n = 18) or anti-interleukin-5/5-receptor (IL-5/5R) (n = 37) biologics. Treatment lasted for an average of 4.1 years. Seventy-five percent (n = 41) had CRSwNP and 25% (n = 14) had CRSsNP. Of all patients, 24% (n = 13) had comorbid AERD and 22% (n = 12) had SOM. Biologic therapy reduced the need for OCS courses (anti-IgE, n = 17, p = 0.03; anti-IL-5/5R, n = 35, p = 0.01) and for daily OCS in anti-IL-5/5R (n = 35, p = 0.001) but not in anti-IgE patients (n = 16, p = 0.07). Biologics also improved NPS by 0.5 point (n = 32, p = 0.009) and SNOT-22 by 14 points (n = 7, p = 0.02) in CRSwNP patients. The overall discontinuation rate was 37.7% (n = 20) and was independent of type of biologic. CONCLUSION: Treatment with anti-IgE and/or anti-IL-5/5R biologics reduced the overall need for OCS medication in individuals with asthma and concomitant CRS, but despite this, the discontinuation rate was high.

Impact of a digital web-based asthma platform, a real-life study.

BACKGROUND: Digital health technology (DHT) is a growing area in the treatment of chronic diseases. Study results on DHT's effect on asthma control have been mixed, but benefits have been seen for adherence, self-management, symptoms, and quality of life. The aim was to evaluate the impact of an interactive web-based asthma treatment platform on asthma exacerbations and health care visits. METHODS: In this real-life study, we retrospectively collected data on adult patients registered on a web-based interactive asthma treatment platform between December 2018 and May 2021. Patients who activated their accounts were active users, and patients who did not were inactive users and considered as controls. We compared the number of exacerbations, total number of exacerbation events defined as the sum of oral corticosteroid (OCS) and antimicrobial courses, emergency room visits, hospitalizations, and asthma-related health care visits before and one year after the registration on the platform. Statistical tests used included the t-test, Pearson's chi-square test and Poisson regression models. RESULTS: Of 147 patients registered on the platform, 106 activated their accounts and 41 did not. The active users had significantly fewer total number of exacerbation events (2.56 per person years, relative decline 0.78, 95% CI 0.6 to 1.0) and asthma-related health care visits (2.38 per person years, relative decline 0.84, 95% CI 0.74 to 0.96) than before registration to the platform, whereas the reductions in health care visits and the total number of exacerbation events were not significant in the inactive users. CONCLUSIONS: An interactive web-based asthma platform can reduce asthma-related health care visits and exacerbations when used actively.
