Severe asthma imposes a significant burden on patients, families and healthcare systems. Management is difficult, due to disease heterogeneity, co‐morbidities, complexity in care pathways and differences between national or regional healthcare systems. Better understanding of the mechanisms has enabled a stratified approach to the management of severe asthma, supporting the use of targeted treatments...
Background
While the clinical characteristics and outcomes of asthma‐chronic obstructive pulmonary disease (COPD) overlap (ACO) have been frequently compared with those of COPD or asthma, the prevalence and features of ACO in patients with severe asthma are unclear.
Objectives
Evaluation of the prevalence and clinical features of ACO using the Korean severe asthma registry.
Methods
At the time...
Background
Recent evidence demonstrates that activated eosinophils undergo a distinct form of lytic cell death, accompanied by formation of DNA‐based eosinophil extracellular trap (EET) and degranulation, enhancing inflammatory immune responses in asthmatic airways. We previously showed that human blood eosinophils undergo degranulation in response to lysophosphatidylserine (LysoPS), an inflammatory...
Dupilumab, a fully human monoclonal antibody against interleukin‐4 receptor α, is approved as add‐on maintenance treatment for inadequately controlled type 2 severe asthma. This systematic review evaluated the efficacy, safety and economic impact of dupilumab compared to standard of care for uncontrolled severe asthma. PubMed, EMBASE and Cochrane Library were searched for RCTs and health economic...
Background
Activated eosinophils release extracellular traps (EETs), which contribute to airway inflammation in severe asthma (SA). However, the role of EETs in innate immunity has not yet been completely determined. The present study aimed to demonstrate the mechanism of airway inflammation in SA mediated by EETs.
Methods
Peripheral counts of EET+ eosinophils and type 2 innate lymphoid cells (ILC2s)...
