Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

2.4K
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

112
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma-II: Pathophysiology and Classification

4.7K
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:

Allergic Reactions: Anaphylaxis01:30

Allergic Reactions: Anaphylaxis

280
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.

Purpose of the Study:

  • To explore the complex interplay between eosinophils and mast cells in various disease contexts.
  • To review the roles of these cells in both allergic/nonclonal and clonal disorders.
  • To discuss current and future therapeutic strategies targeting these cells.

Main Methods:

  • Literature review and synthesis of existing research.
  • Analysis of pathogenetic mechanisms involving eosinophils and mast cells.
  • Discussion of therapeutic interventions and future research directions.

Main Results:

  • Eosinophils and mast cells are frequently found together in both allergic and clonal disorders.
  • Both cell types play significant roles in the pathogenesis of these conditions.
  • The interaction between these cells is crucial but not fully elucidated.

Conclusions:

  • The co-existence and interaction of eosinophils and mast cells are critical in understanding allergic and clonal diseases.
  • Targeting these cells offers potential therapeutic avenues.
