Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

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...

Allergic Reactions: Anaphylaxis

Allergic Reactions: Anaphylaxis

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, heparin),...

Allergic Drug Reactions

Allergic Drug Reactions

Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...

Antibody Structure

Antibody Structure

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Asthma I: Introduction

Asthma I: Introduction

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...

Summary

Family pet ownership is linked to socio-economic factors, not typically to a child's asthma or allergies. Pet avoidance correlates with allergic rhinitis, but not asthma, highlighting the need for prospective pet-keeping data.

Area of Science:

Environmental Health
Epidemiology
Pediatrics

Background:

Pet ownership is a common factor in households with children.
Previous studies on pet keeping and allergic disease development have yielded conflicting results.
Pet avoidance in families with allergic disease history may confound study findings.

Purpose of the Study:

To investigate the association between pet keeping and socio-economic factors in families with children.
To examine the relationship between pet ownership and the development of asthma and allergies in children.
To assess the impact of allergic disease on pet ownership and pet removal.

Main Methods:

A cohort of 1019 children in Oslo was followed until 10 years of age.
Data collected included pet ownership, socio-economic factors, and family history of allergic disease.
Retrospective reporting of pet keeping was analyzed, with attention to recall error.

Main Results:

A family history of asthma or rhinoconjunctivitis was not significantly associated with pet ownership at birth or pet removal by age 10.
Acquiring cats and dogs was less likely in children with allergic rhinoconjunctivitis, but not associated with asthma.
Socio-economic factors, including single parenthood and parental smoking, significantly influenced pet acquisition decisions.

Conclusions:

Allergic disease in a child does not commonly lead to pet removal.
Pet avoidance is linked to allergic rhinitis symptoms, but not asthma.
Socio-economic factors are strong predictors of pet keeping, underscoring the need for prospective data collection.
