Relationships between Chronic Cough and Asthma Control and Quality-of-Life in Patients with Severe Asthma: A 6-Month Longitudinal Analysis.
Background: The prevalence and clinical implications of chronic cough (CC) in patients with severe asthma receiving asthma treatment remain relatively unknown.
Objective: This study aimed to evaluate the relationships between CC and asthma control and quality-of-life (QoL) in patients with severe asthma through longitudinal analysis.
Methods: Baseline and 6-month follow-up data from the Korean Severe Asthma Registry were analyzed. CC was defined as a cough visual analog scale (VAS) score of ≥40 at both baseline and 6-months. Demographic parameters and clinical outcomes were compared between patients with severe asthma and CC and those without CC. Generalized estimating equation (GEE) analysis was performed to identify associations of CC with asthma control and QoL scores.
Results: Of the total 286 participants with severe asthma, 116 (40.6%) were defined as having CC. Patients with CC had higher baseline cough and wheeze severity VAS scores (all P<0.001), poorer asthma control (P<0.001), and worse QoL (Severe Asthma Questionnaire [SAQ] and Euro-QoL 5-dimension [EQ-5D] index, all P<0.001), compared to those without CC. During follow-up, patients with CC were more frequently exposed to oral corticosteroids (58.6% vs. 38.6%, P=0.010) and experienced more frequent asthma exacerbations (48.3% vs. 28.6%, P=0.009) than those without CC. GEE analysis revealed that CC was independently associated with poor asthma control, lower SAQ scores, and lower EQ-5D index after adjusting for confounders.
Conclusion: The presence of CC was associated with worse asthma control and QoL in patients with severe asthma. Further studies are warranted to better evaluate and manage CC in these patients.
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.
