Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

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: Pathogenesis and Management01:20

Asthma: 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.

Asthma-I: Introduction01:29

Asthma-I: Introduction

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...

Drugs Used in Lower Respiratory Disorders: Overview

Lower respiratory tract disorders present challenges that often require skilled and nuanced approaches for effective management. Common ailments, such as asthma and chronic obstructive pulmonary disease (COPD), have prompted the development of intricate treatment strategies involving bronchodilators and anti-inflammatory drugs, each tailored to ease breathing and revitalize the lungs.
Bronchodilators, the first step of respiration enhancement, come in various forms, each with its own mechanism...

Allergy prevention is shifting from avoiding risks to promoting tolerance in infants. Early life interventions aim to modulate the immune system, potentially reversing rising allergy trends.

Area of Science:

  • Pediatrics
  • Immunology
  • Public Health

Background:

  • Allergic diseases and atopy are increasing in children, becoming a 21st-century epidemic.
  • Current public health concerns focus on the rising prevalence of atopy and asthma in industrialized nations.
  • Limited understanding of atopic sensitization, dermatitis, and allergic airway disease hinders effective prevention.

Purpose of the Study:

  • To explore a paradigm shift in allergy prevention strategies for infants and young children.
  • To investigate the potential of immune modulation and tolerance induction for preventing allergies.
  • To identify necessary risk factors and determinants for effective early-life allergy interventions.

Main Methods:

  • Review of current allergy prevention strategies, contrasting risk avoidance with protective factor introduction.

  • Analysis of the shift towards immune modulation and tolerance induction in early life.
  • Emphasis on the need for understanding natural history and risk factors for intervention development.

    • Main Results:

    • A paradigm shift in allergy prevention is emerging, focusing on early immune modulation.
    • Providing protective factors to infants may induce tolerance to allergens.
    • Understanding risk factors is crucial for developing effective preventive interventions.

    Conclusions:

    • Early-life interventions focusing on immune modulation and tolerance are promising for allergy prevention.
    • Reversing the rising trend of allergic diseases requires a focus on protective factors in infancy.
    • Further research into the natural history of atopic sensitization is essential for public health strategies.
