Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

2.0K
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...

Asthma-I: Introduction

3.6K
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...

Allergic Reactions: Anaphylaxis01:30

Allergic Reactions: Anaphylaxis

62
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin,...

Asthma: Pathogenesis and Management

1.5K
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.

Area of Science:

  • Immunology and Allergy
  • Respiratory Medicine
  • Pharmacology

Background:

  • The efficacy of allergen-specific immunotherapy (AIT) for asthma remains a subject of ongoing debate and research.
  • Recent advancements focus on identifying patient subsets and developing novel vaccine formulations.

Purpose of the Study:

  • To review recent publications (2024-2025) on allergen immunotherapy for asthma.
  • To assess the current evidence regarding AIT's effectiveness and safety in asthma management.

Main Methods:

  • Literature review of studies published in 2024 and 2025 concerning AIT for asthma.
  • Analysis of clinical trial outcomes, genetic associations, and emerging vaccine technologies.

Main Results:

  • House dust mite immunotherapy showed positive results in a subset of patients with specific genetic variants (chromosome 17q12-21).
  • Cockroach immunotherapy yielded negative results in nasal challenge but showed promising T-cell effects.
  • New allergoid and adjuvant vaccines are under development, aiming for fewer injections and improved safety.
  • Trained immunity vaccines (bacterial lysates) demonstrated potential in reducing wheezing in children.
  • Reviews indicate AIT can reduce asthma symptoms and medication needs, but not objective lung function measures.
  • Combining biologics with AIT may enhance safety.

Conclusions:

  • Allergen-specific immunotherapy is valuable for allergic rhinitis and conjunctivitis and can be safely used in well-controlled mild to moderate asthma.
  • Emerging AIT approaches show promise but require substantial further investigation and validation.
