Allergic Drug Reactions

1.5K
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...

Allergic Reactions: Anaphylaxis01:30

Allergic Reactions: Anaphylaxis

62
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,...

Hypersensitivity Reactions: Immune-Complex Reactions01:19

Hypersensitivity Reactions: Immune-Complex Reactions

62
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum...

Drug Toxicity: Allergic Reactions

59
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...

Hypersensitivities01:30

Hypersensitivities

7.9K
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...

Area of Science:

  • Allergy and Immunology
  • Molecular Diagnostics

Background:

  • Component-resolved diagnostics (CRD) analyzes IgE-mediated sensitizations using defined allergen molecules.
  • Hymenoptera venom allergy (HVA) diagnosis benefits from molecular-level analysis.

Purpose of the Study:

  • Review recent studies on CRD in HVA.
  • Discuss the benefits and limitations of CRD in HVA management.

Main Methods:

  • Review of recent scientific literature on CRD in HVA.
  • Analysis of IgE reactivity to specific venom allergens and panels.
  • Correlation of sensitization profiles with clinical outcomes and immunotherapy response.

Main Results:

  • CRD in HVA has advanced from single allergens to comprehensive panels.
  • Detection of specific IgE aids in differentiating primary sensitization from cross-reactivity, improving venom immunotherapy (VIT) rationale.
  • Identified distinct sensitization profiles in honeybee venom allergy linked to VIT side effects or failure.
  • CRD currently lacks reliable markers for differentiating sensitizations within Vespidae family.

Conclusions:

  • CRD enhances understanding of HVA sensitization complexity and cross-reactivities.
  • Potential for identifying biomarkers for risk stratification in VIT.
  • Enables personalized VIT preparation selection based on individual sensitization profiles, aligning with precision medicine goals.
