Airway disease: similarities and differences between asthma, COPD and bronchiectasis

Area of Science:

• Pulmonary Medicine
• Respiratory Diseases

Background:

• Airway diseases, including asthma, chronic obstructive pulmonary disease (COPD), and bronchiectasis, are globally prevalent but often underestimated.
• These conditions share common characteristics and pathophysiological pathways, leading to overlapping symptoms and diagnostic challenges.

Purpose of the Study:

• To review and highlight the similarities and differences between asthma, COPD, and bronchiectasis.
• To emphasize the importance of early differentiation for appropriate therapeutic interventions.

Main Methods:

• Literature review focusing on risk factors, pathophysiology, clinical presentation, diagnostic methods, and treatment strategies for asthma, COPD, and bronchiectasis.

Main Results:

• Asthma, COPD, and bronchiectasis exhibit distinct epidemiological profiles, etiological factors, and pathobiological mechanisms.
• Despite overlapping symptoms, key differences in diagnostic markers and treatment responses exist.
• Early and accurate diagnosis is critical for optimizing patient outcomes and managing disease progression.

Conclusions:

• Distinguishing between asthma, COPD, and bronchiectasis early is essential for guiding clinical management and improving patient prognosis.
• Understanding the nuances of these airway diseases facilitates the selection of targeted therapies.
