Glucocorticoids are essential for treating asthma by reducing bronchial inflammation. However, understanding individual patient sensitivity to these steroids remains a challenge for effective treatment.
Area of Science:
- Pulmonology
- Pharmacology
- Immunology
Background:
- Bronchial inflammation is a key factor in asthma, leading to bronchoconstriction and hyperreactivity.
- Glucocorticoids are the primary treatment for asthma, targeting multiple inflammatory pathways.
- Inhaled corticosteroids are widely recommended for early asthma management.
Purpose of the Study:
- To explore the mechanisms of glucocorticoid action in bronchial inflammation.
- To address the challenges in evaluating individual patient sensitivity to glucocorticoids.
- To understand the variability in glucocorticoid response among asthma patients.
Main Methods:
- Review of molecular and cellular mechanisms of glucocorticoid action.
- Analysis of glucocorticoid interaction with inflammatory and structural cells.
- Examination of gene transcription modulation via cytoplasmic receptors.
Main Results:
- Glucocorticoids affect all inflammatory and structural cells in the airways.
- The mechanism involves binding to cytoplasmic receptors and influencing DNA transcription.
- While most patients respond, a small subset shows insensitivity, necessitating further investigation.
- Individual variability in glucocorticoid sensitivity exists but is not fully understood in asthmatics.
Conclusions:
- Glucocorticoids are crucial for managing asthma by targeting bronchial inflammation.
- Individual sensitivity to glucocorticoids varies, and identifying non-responders requires further research.
- Defining and adapting criteria for glucocorticoid responders and non-responders is essential for personalized asthma care.

Asthma: Pathogenesis and Management
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: Leukotriene Modifiers
Leukotriene modifiers work through two distinct mechanisms:
Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
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...
