Allergic Reactions

Overview
Hypersensitivities01:30

Hypersensitivities

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...
Allergic Reactions: Anaphylaxis01:30

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),...
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs01:25

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...
Drug Toxicity: Allergic Reactions01:30

Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
Allergic Drug Reactions01:27

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...

Summary

Occupational allergy to wheat flour can be treated with subcutaneous specific immunotherapy (SCIT), allowing most bakers to continue their work with improved quality of life and reduced symptoms.

Area of Science:

  • Immunology
  • Occupational Health
  • Allergology

Context:

  • Occupational allergy to wheat flour causes rhinitis and asthma in bakery workers.
  • IgE-mediated immune mechanisms are involved.
  • Specific immunotherapy (SCIT) using wheat flour extract is now available.

Purpose:

  • To evaluate the long-term effectiveness of SCIT in allergic bakery workers.
  • To assess the impact of SCIT on workers' ability to continue their profession.
  • To determine if SCIT reduces allergic symptoms and improves quality of life.

Summary:

  • An observational study followed 41 sensitized workers undergoing SCIT for 4+ years without job avoidance.
  • After 5-10 years, 34/41 workers remained employed with acceptable quality of life and work efficiency.
  • Both previously treated and currently treated groups showed positive outcomes, with symptom reduction and decreased medication use in the majority.

Impact:

  • SCIT appears to be a viable treatment for occupational wheat flour allergy.
  • This immunotherapy can help prevent job relocation and improve workers' lives.
  • SCIT may be combined with environmental prevention strategies for enhanced workplace safety.
