    Hereditary alpha-1-antitrypsin deficiency is linked to progressive bronchiectasis without emphysema in three patients. This finding expands understanding of lung disease in alpha-1-antitrypsin deficiency beyond typical emphysema associations.

    Area of Science:

    • Pulmonology
    • Genetics
    • Internal Medicine

    Background:

    • Hereditary alpha-1-antitrypsin deficiency is commonly associated with pulmonary emphysema and chronic bronchitis.
    • Bronchiectasis without emphysema is a rare manifestation of alpha-1-antitrypsin deficiency, with only one prior report.
    • Progressive lung disease necessitates a comprehensive understanding of its varied clinical presentations.

    Observation:

    • Three patients presented with progressive bronchiectasis.
    • These patients showed no radiographic evidence of emphysema.
    • All three patients were diagnosed with alpha-1-antitrypsin deficiency.

    Findings:

    • This case series highlights progressive bronchiectasis as a potential manifestation of alpha-1-antitrypsin deficiency.

  • The absence of emphysema in these cases is notable, contrasting with typical presentations.
  • This suggests a broader spectrum of lung disease in alpha-1-antitrypsin deficiency.

    • Implications:

    • Clinicians should consider alpha-1-antitrypsin deficiency in patients with unexplained bronchiectasis, even without emphysema.
    • Further research is warranted to understand the mechanisms linking alpha-1-antitrypsin deficiency to bronchiectasis.
    • Early diagnosis and management of alpha-1-antitrypsin deficiency can potentially mitigate severe lung damage.
