Asthma: Pathogenesis and Management01:20

Asthma: Pathogenesis and Management

529
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.

Asthma-I: Introduction

2.8K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma-II: Pathophysiology and Classification

2.8K
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:

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

405
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
  • Allergy and Immunology
  • Translational Medicine

Background:

  • The traditional asthma management approach based on severity is outdated.
  • Asthma is a heterogeneous syndrome, not a single disease entity, necessitating personalized treatment strategies.

Purpose of the Study:

  • To highlight the underutilization of asthma phenotyping and biomarkers in clinical practice.
  • To emphasize the need for integrating clinical features and biomarkers for advancing precision medicine in asthma.

Main Methods:

  • Review of studies on asthma phenotypes and clusters.
  • Analysis of the role of biomarkers such as eosinophils, fractional exhaled nitric oxide (FeNO), and immunoglobulin E (IgE).
  • Discussion on the importance of clinical features in predicting treatment response and outcomes.

Main Results:

  • Asthma phenotyping using clusters reveals heterogeneity but lacks direct clinical application.
  • Biomarkers like T2 inflammation, eosinophils, FeNO, and IgE are valuable but variably utilized.
  • Clinical features are crucial for phenotypic characterization and predicting therapeutic response.

Conclusions:

  • Precision medicine in asthma requires a shift from a one-size-fits-all approach.
  • Integrating clinical features and biomarkers into composite scores and risk prediction tools is essential for effective asthma management.
  • Further research is needed to identify non-T2 biomarkers and promote wider adoption of phenotyping and biomarker use in clinical practice.
