Complete response to anti-interleukin-5 biologics in a real-life setting:results from the nationwide Danish Severe Asthma Register

BACKGROUND: Phase III regulatory trials show that anti-interleukin (IL)-5 biologics efficiently reduce exacerbations and the use of maintenance oral corticosteroids (mOCS) in patients with severe eosinophilic asthma. However, patients eligible for these trials differ significantly compared with real-life severe asthma populations. Therefore, our aim was to explore efficacy in a real-life setting. The Danish Severe Asthma Register (DSAR) is a complete, nationwide register that comprises all Danish patients on biological therapy for severe asthma. METHODS: This prospective study identified patients in the DSAR who were complete responders to anti-IL-5 biologics after 1 year of treatment. A complete response was defined as resolution of the parameter setting the indication, i.e. recurrent exacerbations and/or use of mOCS. RESULTS: A total of 289 out of 502 (58%) patients were complete responders to anti-IL-5 biologics after 12 months. Complete responders had greater improvements in forced expiratory volume in 1 s and Asthma Control Questionnaire (ACQ) score compared with noncomplete responders (Δ 210 versus 30 mL; p<0.0001 and Δ −1.04 versus −0.68; p=0.016, respectively). A complete response was predicted by age at onset, less severe disease at baseline (i.e. no mOCS and lower ACQ score) and higher blood eosinophils. CONCLUSIONS: More than half of Danish patients treated with anti-IL-5 biologics for severe asthma achieve a complete response to treatment, thereby becoming free from asthma exacerbations and the need for mOCS. Complete responders also achieved superior effects on lung function and symptoms compared with noncomplete responders

Analysis of comorbidities and multimorbidity in adult patients in the International Severe Asthma Registry

Q2Q2Pacientes con Asma severaBackground: Investigation for the presence of asthma comorbidities is recommended by GINA as their presence can complicate asthma management. Objective: To understand the prevalence and pattern of comorbidities and multimorbidity in adults with severe asthma and their association with asthma-related outcomes. Methods: This was a cross-sectional study using data from the International Severe Asthma Registry from 22 countries. Thirty comorbidities were identified and categorized a priori as either (1) potentially T2-related, (2) potentially oral corticosteroid (OCS)-related or (3) mimicking/aggravating asthma. The association between comorbidities and asthma-related outcomes was investigated using multivariable models adjusted for country, age at enrollment, and sex. Results: Of 11,821 patients, 69%, 67%, and 55% had ≥1 potentially T2-related, potentially OCS-related, or mimicking/aggravating comorbidities, respectively; 57% had ≥3 comorbidities, and 33% had comorbidities in all three categories. Patients with allergic rhinitis (AR), nasal polyposis (NP), and chronic rhinosinusitis (CRS) experienced 1.12- (p=0.003), 1.16- (p<0.001) and 1.29-times (p<0.001) more exacerbations/year, respectively, than those without. Patients with NP and CRS were 40% and 46% more likely (p<0.001), respectively, to have received long-term (LT) OCS. All assessed potential OCS-related comorbidities (except obesity) were associated with greater likelihood of LTOCS use (ORs: 1.23-2.77) and, except for dyslipidemia, with greater likelihood of uncontrolled asthma (ORs: 1.29-1.68). All mimicking/aggravating comorbidities assessed were associated with more exacerbations (1.24-1.68 times more), all (except bronchiectasis) with increased likelihood of uncontrolled asthma (ORs: 1.57-1.81) and all (except COPD) with increased likelihood of LTOCS use (ORs: 1.37-1.57). Greater number of comorbidities was associated with worse outcome. Conclusion: In a global study, comorbidity or multimorbidity is reported in most adults with severe asthma and is associated with poorer asthma-related outcomes.https://orcid.org/0000-0001-8405-4513https://orcid.org/0000-0002-0100-1940https://orcid.org/0000-0001-6461-2725Revista Internacional - IndexadaA1N
