Area of Science:

  • Pulmonology
  • Immunology
  • Pharmacology

Background:

  • Asthma is a chronic respiratory disease characterized by airway inflammation.
  • The role of distal lung inflammation in asthma pathophysiology is increasingly recognized.

Purpose of the Study:

  • To review the current understanding of distal lung inflammation in asthma.
  • To discuss advancements in diagnosis and treatment targeting the distal lung.

Main Methods:

  • Literature review of peer-reviewed publications.
  • MEDLINE database search focusing on pathophysiology, diagnosis, and treatment.
  • Analysis of bibliographies from selected articles.

Main Results:

  • Distal lung inflammation, affecting small airways and alveolar tissue, is crucial to asthma's clinical presentation.

  • Advanced diagnostic methods like transbronchial biopsy and high-resolution computed tomography (HRCT) enhance evaluation of the distal lung.
  • Novel treatments, including ultra-fine particle inhalers and cysteinyl leukotriene receptor antagonists, show promise for targeting distal inflammation.

    • Conclusions:

    • Distal lung inflammation is a key component of overall airway inflammation in asthma.
    • Emerging diagnostic and therapeutic strategies are expanding knowledge and potential treatments for distal lung inflammation in asthma.
    • Targeting distal lung inflammation may become critically important in future asthma management.
