Allergic Drug Reactions

1.3K
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...

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.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

1.6K
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...

Summary
This summary is machine-generated.

Egg allergy affects many young children, but most can tolerate baked eggs. Identifying baked egg tolerance in children with egg allergy can reduce their psychosocial burden.

Area of Science:

  • Pediatric Allergy and Immunology
  • Epidemiology of Food Allergies
  • Public Health Nutrition

Background:

  • Egg allergy is a prevalent food allergy in children under five years old.
  • It significantly impacts children's quality of life and daily functioning.
  • Understanding prevalence and characteristics is crucial for management.

Purpose of the Study:

  • To determine the prevalence and severity of egg allergy in a large US pediatric cohort.
  • To investigate the rate of baked egg tolerance among children with egg allergy.
  • To identify associated factors, including comorbidities and demographic differences.

Main Methods:

  • A national cross-sectional survey was conducted from October 2015 to September 2016.
  • Parent-proxy responses were collected from 38,408 children.
  • Weighted proportions were used to analyze prevalence and compare subpopulations.

Main Results:

  • The prevalence of egg allergy was 0.9% overall and 1.3% in children under five.
  • Black children were disproportionately represented among those with egg allergy.
  • 64.2% of egg-allergic children showed tolerance to baked eggs, and 46.5% had co-occurring asthma.

Conclusions:

  • Egg allergy is common in young children, with a significant portion tolerating baked eggs.
  • Appropriate evaluation is needed to identify comorbid conditions and assess baked egg tolerance.
  • Determining baked egg tolerance can potentially improve the quality of life for affected children.
