Bronchiectasis in women may act more virulently. Identified gender and sex differences range from increased exposure risks to altered inflammatory responses. Common among the most well-documented examples is a differential immune response. There is sufficient evidence to suggest that chronic airway infection, most notably non-CF bronchiectasis, is a more common and more virulent disease in women. This is particularly evident in CF-and non-HIV-related environmental mycobacterial respiratory tract infections. Whether this represents an inflammatory-immune process, or environmental, anatomic, or other genetic difference remains to be detailed fully.

Retrospective cross-sectional study on bronchiectasis in adult Aboriginal Australians: disease characteristics and comparison with ethnically diverse global bronchiectasis registry cohorts.
BMJ Open Respir Res
January 2025
Darwin Respiratory and Sleep Health, Darwin Private Hospital, Darwin, Northern Territory, Australia.
Background: Globally, adult Indigenous people, including Aboriginal Australians, have a high burden of chronic respiratory disorders, and bronchiectasis is no exception. However, literature detailing bronchiectasis disease characteristics among adult Indigenous people is sparse. This study assessed the clinical profile of bronchiectasis among adult Aboriginal Australians and compared against previously published international bronchiectasis registry reports.

Department of Epidemiology, University of Groningen, University Medical Center Groningen, Groningen, The Netherlands.
Objective: To assess the co-occurrence of incidental CT lung findings (emphysema, bronchiectasis, and airway wall thickening) as well as associated risk factors in low-dose CT (LDCT) lung cancer screening in a Chinese urban population.
Methods: Data from 978 participants aged 40-74 years from the Chinese NELCIN-B3 urban population study who underwent LDCT screening were selected. CT scans were reviewed for incidental lung findings: emphysema, bronchiectasis and airway wall thickness.
Eosinopenia in bronchiectasis: A novel biomarker for morbidity and mortality.
Chron Respir Dis
January 2025
Pulmonary Institute, Rabin Medical Center - Beilinson Hospital, Petach Tikva, Israel.
Background: The paradigm of bronchiectasis is shifting away from its exclusive characterization as a neutrophilic condition. Patients with bronchiectasis and high eosinophil levels have been found to have a specific phenotype, but the clinical effect of eosinopenia remains unclear.
Method: A retrospective, single-center, observational study was conducted at a tertiary medical center.
Autoantibodies targeting interferons and GM-CSF are associated with adverse outcome risk, comorbidities, and pathogen in community-acquired pneumonia.

Department of Clinical Immunology, Copenhagen University Hospital, Rigshospitalet, Copenhagen, Denmark.
Introduction: Cytokine autoantibodies (c-aAb) have been associated with pulmonary diseases, including severe novel coronavirus disease 2019 (COVID-19) and pulmonary alveolar proteinosis. This study aimed to determine c-aAb association with community-acquired pneumonia (CAP) etiology (SARS-CoV-2, influenza, or bacteria) and c-aAb associations with CAP-related clinical outcomes and pulmonary comorbidities.
Methods: In a cohort of 665 patients hospitalized with CAP, c-aAb targeting interferon α (IFNα), IFNβ, IFNγ, interleukin-1α (IL-1α), IL-6, IL-10, and granulocyte-macrophage colony-stimulating factor (GM-CSF) were measured in plasma samples.
