Abstract
Background: Clinical remission (CR) is a new realistic management goal for patients with asthma, regardless of the disease severity.
Objective: To investigate the rate of achievement of CR in patients treated with inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) and nonbiologics and the characteristics of patients who achieved CR.
Methods: We performed a post hoc analysis from a multicenter, cross-sectional survey in Japan. 3-way CR was defined as the absence of exacerbation, no use of maintenance oral corticosteroids, and the absence of significant asthma symptoms (5-item Asthma Control Questionnaire < 1.5). We defined 4-way CR as 3-way CR plus having normalized lung function (forced expiratory volume in 1 second [%FEV1] ≥ 80%). Deep remission was defined as 4-way CR plus suppressed type 2 airway inflammation (fraction of exhaled nitric oxide [FeNO] < 35 ppb).
Results: The criteria for 3-way CR, 4-way CR, and deep remission were met by 56.9%, 35.0%, and 24.7% of patients, respectively. Compared with patients who achieved the 3-way CR, unachieved patients have lower %FEV1 (77.6% vs 85.4%; P < .0001) and higher FeNO levels (42 ppb vs 34 ppb; P = .0182), and there were more discordances in asthma control perception between patient and physicians (38.5% vs 9.3%; P < .0001). Physician-patient discordance was an independent factor that prevented the achievement of the 3-way CR in the logistic regression analysis, even when adjusted for %FEV1 and FeNO (odds ratio 0.397; P < 0.0001).
Conclusions: Achieving CR in patients treated with ICS/LABA without biologics is challenging. Discrepancies between patient and physician perceptions on asthma control are significant barriers to achieving CR.
期刊介绍：
JACI: In Practice is an official publication of the American Academy of Allergy, Asthma & Immunology (AAAAI). It is a companion title to The Journal of Allergy and Clinical Immunology, and it aims to provide timely clinical papers, case reports, and management recommendations to clinical allergists and other physicians dealing with allergic and immunologic diseases in their practice. The mission of JACI: In Practice is to offer valid and impactful information that supports evidence-based clinical decisions in the diagnosis and management of asthma, allergies, immunologic conditions, and related diseases.
This journal publishes articles on various conditions treated by allergist-immunologists, including food allergy, respiratory disorders (such as asthma, rhinitis, nasal polyps, sinusitis, cough, ABPA, and hypersensitivity pneumonitis), drug allergy, insect sting allergy, anaphylaxis, dermatologic disorders (such as atopic dermatitis, contact dermatitis, urticaria, angioedema, and HAE), immunodeficiency, autoinflammatory syndromes, eosinophilic disorders, and mast cell disorders.
The focus of the journal is on providing cutting-edge clinical information that practitioners can use in their everyday practice or to acquire new knowledge and skills for the benefit of their patients. However, mechanistic or translational studies without immediate or near future clinical relevance, as well as animal studies, are not within the scope of the journal.
