Summary: This study compared the eosinophil phenotypes in blood and induced sputum among patients with COPD, asthma, and controls. It was found that the eosinophil phenotype in COPD patients' sputum differed from that of the other groups, indicating a distinct phenotype of eosinophils in COPD patients compared to asthma or healthy individuals.

Summary: This study demonstrates a novel mechanism of bronchial smooth muscle (BSM) remodeling in patients with severe asthma following rhinovirus (RV) exacerbation. The specific migration of BSM cells towards RV-infected bronchial epithelium (BE) is driven by the chemokine ligand C-X-C motif chemokine ligand 10. Decreased expression and activation of the CXCR3-B-specific isoform in BSM cells from patients with severe asthma contribute to this mechanism. These findings highlight the potential therapeutic target of the C-X-C motif chemokine ligand 10/CXCR3-A axis in severe asthma.

Summary: Eosinophilic inflammation is a key feature of asthma, with distinct types of eosinophils influencing airway smooth muscle cell proliferation and viability through integrins. In asthma patients, exposure to specific allergens can enhance the pro-proliferative properties of inflammatory eosinophils, while resident eosinophils have a stronger effect on stimulating smooth muscle cell proliferation and viability.

Summary: The study showed that benralizumab can improve symptoms of NP and asthma outcomes in patients with severe, eosinophilic asthma and NP, with better effects observed in patients with high baseline SNOT-22 scores.

Summary: Patients with highly variable sputum eosinophil percentages reported more asthma exacerbations, while those with predominantly elevated eosinophil percentages experienced greater loss of lung function over three years. The presence of neutrophils did not have a significant impact on asthma severity.

Summary: Evaluation and management of severe asthma remains a core focus in pulmonary practice. Advances in clinical phenotyping and molecular tools have greatly enhanced our understanding and treatment of severe asthma. Challenges still exist, but conceptual understanding of the disease has evolved significantly in a relatively short period of time.

Summary: The OSMO study showed that switching to mepolizumab resulted in beneficial responses in nearly all patients with uncontrolled severe eosinophilic asthma previously treated with omalizumab, regardless of baseline characteristics.

Summary: The study shows that bronchial thermoplasty can significantly reduce airway smooth muscle mass and treatment response is associated with serum IgE and eosinophil levels, rather than baseline ASM mass.

Summary: Extracellular vesicles (EVs) from LPS-stimulated neutrophils increased ASM proliferation, regardless of asthma severity. During disease exacerbation, certain proteins were significantly upregulated in neutrophil EVs, indicating an altered proteomic profile due to LPS stimulation.

Summary: Asthma is now recognized as a heterogeneous disease with different phenotypes driven by distinct pathophysiological mechanisms. Eosinophilic asthma is a common phenotype characterized by the presence of eosinophils, which have become a primary therapeutic target. Recent research suggests that different SEA phenotypes may involve differences in eosinophil biology.

Summary: This article presents recommendations for managing severe asthma based on clinical variables and treatment options. Expert opinions were provided on investigating biomarker levels, clinical features, and safety considerations. The current evidence suggests the importance of biomarker measurements and the impact of oral corticosteroid use on biologic selection.

Summary: This article reviews the clinical assessment of a 56-year-old man with difficult-to-control asthma and a history of exacerbations, highlighting the importance of identifying different asthma phenotypes and using biomarkers to guide treatment decisions. The patient was found to have severe asthma with ICS-resistant type 2 airway inflammation, and additional treatment options will be considered in the future.

Summary: A survey of Asian respiratory specialists revealed discrepancies in bronchiectasis management in Asian populations, partly due to limited treatment availability in each country. Developing local guidelines considering phenotypes and practical situations could help standardize and improve bronchiectasis management.
