Asthma-II: Pathophysiology and Classification01:26

Asthma-II: Pathophysiology and Classification

2.6K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Asthma: Pathogenesis and Management

359
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

237
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Area of Science:

  • Pulmonology
  • Respiratory Medicine
  • Asthma Research

Background:

  • Small airways, or the lung's silent zone, are critical in asthma management.
  • Dysfunction in small airways correlates with poor symptom control and increased asthma exacerbations.
  • Personalized asthma care is evolving through the 'treatable traits' paradigm.

Purpose of the Study:

  • To review the literature on small airways dysfunction as a treatable trait in persistent asthma.
  • To explore the role of oscillometry in assessing small airways.
  • To examine the impact of advanced therapies on peripheral airway disease.

Main Methods:

  • Literature review of studies on small airways dysfunction in asthma.
  • Analysis of oscillometry techniques (whole- and intrabreath).
  • Evaluation of evidence for extrafine inhaled corticosteroids and systemic biologics in peripheral airway treatment.

Main Results:

  • Small airways dysfunction is a significant factor in persistent asthma.
  • Oscillometry provides valuable insights into airflow resistance and reactance.
  • Extrafine inhaled corticosteroids and systemic biologics show potential in managing peripheral airway obstruction.

Conclusions:

  • Small airways dysfunction represents a key treatable trait in asthma.
  • Oscillometry is a promising tool for diagnosing and monitoring small airways disease.
  • Targeted therapies offer new avenues for personalized asthma management.
