Abstract:
Chronic obstructive pulmonary disease (COPD) and bronchiectasis represent chronic airway diseases associated with significant morbidity and mortality. Bacteria and viruses are commonly implicated in acute exacerbations; however the significance of fungi in these airways remains poorly defined. While COPD and bronchiectasis remain recognized risk factors for the occurrence of Aspergillus-associated disease including chronic and invasive aspergillosis, underlying mechanisms that lead to the progression from colonization to invasive disease remain uncertain. Nonetheless, advances in molecular technologies have improved our detection, identification and understanding of resident fungi characterizing these airways. Mycobiome sequencing has revealed the complex varied and myriad profile of airway fungi in COPD and bronchiectasis, including their association with disease presentation, progression, and mortality. In this review, we outline the emerging evidence for the clinical importance of fungi in COPD and bronchiectasis, available diagnostic modalities, mycobiome sequencing approaches and association with clinical outcomes.
Insights
Fungi play a significant role in chronic obstructive pulmonary disease (COPD) and bronchiectasis exacerbations. Understanding airway mycobiomes improves diagnosis and treatment for these chronic airway diseases.
Area of Science:
- Pulmonology and Medical Mycology
Background:
- Chronic obstructive pulmonary disease (COPD) and bronchiectasis are major causes of illness and death.
- Fungal roles in exacerbations of these chronic airway diseases are not well understood.
- Aspergillus species are linked to COPD and bronchiectasis, but progression from colonization to invasive disease is unclear.
Purpose of the Study:
- To review the clinical significance of fungi in COPD and bronchiectasis.
- To discuss diagnostic methods and mycobiome sequencing for airway fungi.
- To explore associations between airway fungi and clinical outcomes.
Main Methods:
- Review of emerging evidence on fungal infections in chronic airway diseases.
- Analysis of diagnostic modalities for fungal detection.
- Examination of mycobiome sequencing data and its clinical correlations.
Main Results:
- Advances in molecular technology enhance the detection and identification of airway fungi.
- Mycobiome sequencing reveals diverse fungal profiles in COPD and bronchiectasis.
- Fungal presence is associated with disease presentation, progression, and mortality.
Conclusions:
- Fungi are clinically important in COPD and bronchiectasis.
- Mycobiome analysis offers insights into disease mechanisms and outcomes.
- Further research is needed to clarify fungal roles and optimize management strategies.
