Hypersensitivities

540
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

241
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...

Antibody Structure

59.6K
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...

Allergic Drug Reactions

818
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...

Area of Science:

  • Pediatric Allergy and Immunology
  • Food Science and Nutrition

Background:

  • Legumes are a vital global protein source, with increasing food industry interest in their use as cereal substitutes.
  • Legume consumption is associated with IgE-mediated allergies, and rising intake may increase allergy incidence.
  • The prevalence and common causative legumes in allergies vary regionally, with distinct patterns in Western countries versus the Mediterranean and India.

Purpose of the Study:

  • To review the scientific literature on legume allergy in children.
  • To propose a diagnostic workup for pediatric legume allergy.
  • To outline a therapeutic approach for managing legume allergy in children.

Main Methods:

  • Systematic review of scientific literature on legume allergy in pediatric populations.
  • Analysis of epidemiological data on legume allergy prevalence and regional variations.
  • Synthesis of current diagnostic criteria and therapeutic strategies for legume allergy.

Main Results:

  • Peanuts and soybeans are primary allergens in Western countries, while lentils, peas, and chickpeas are more common in the Mediterranean and India.
  • IgE-mediated allergy is a known risk associated with legume consumption.
  • The review consolidates information on the presentation and management of legume allergies in children.

Conclusions:

  • Legume allergy is a significant concern in pediatric populations, with regional differences in causative agents.
  • A standardized diagnostic workup and therapeutic approach are essential for effective management.
  • Further research may be needed to fully understand and mitigate the impact of increasing legume consumption on allergy incidence.
