Summary
The three-step sequential method (TSSM) significantly improved corticosteroid-dependent asthma (SDA) by balancing Th1/Th2 immune responses, reducing inflammation, and improving lung function. This approach alleviates symptoms and decreases reliance on corticosteroids.
Area of Science:
- Immunology
- Pulmonology
- Pharmacology
Context:
- Corticosteroid-dependent asthma (SDA) presents a significant clinical challenge.
- Current treatments often involve long-term corticosteroid use, leading to potential side effects.
- Understanding novel therapeutic mechanisms is crucial for managing SDA.
Purpose:
- To investigate the therapeutic mechanism of the three-step sequential method (TSSM) in patients with SDA.
- To evaluate the efficacy of TSSM combined with inhaled corticosteroids compared to inhaled corticosteroids alone.
- To assess the impact of TSSM on immune cell profiles, specifically T-helper cell responses.
Summary:
- Forty patients with SDA were randomized into two groups: one receiving TSSM plus inhaled Pulmicort Turbuhaler, the other receiving Pulmicort Turbuhaler alone.
- Treatment duration was 12-14 weeks, with assessments of asthma symptom scores, corticosteroid dosage, lung function, and T-helper cell cytokine expression (IFN-gamma and IL-4).
- The TSSM group showed significantly greater improvements in symptom scores, reduced corticosteroid dosage, and enhanced lung function compared to the control group.
Impact:
- TSSM effectively regulates the Th1/Th2 immune imbalance in SDA patients.
- The method inhibits inflammatory cytokine generation and reduces airway hyper-responsiveness.
- TSSM improves pulmonary function, alleviates asthmatic symptoms, and reduces corticosteroid dependence.

01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
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...

01:13Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
01:26Asthma-II: Pathophysiology and Classification
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:

01:24Asthma-III: Symptoms and Complications
Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

01:20Asthma: Pathogenesis and Management
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.

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...
