Allergic Reactions: Anaphylaxis01:30

Allergic Reactions: Anaphylaxis

116
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,...

Allergic Drug Reactions

1.6K
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...

Drug Toxicity: Allergic Reactions

100
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

8.1K
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
  • Toxicology
  • Ethnobotany

Background:

  • Semecarpus anacardium, known as marking nut, is recognized for causing contact hypersensitivity due to its pigment.
  • The plant is sometimes consumed as a component of traditional Hindi cuisine.
  • Anaphylaxis is a severe, potentially life-threatening allergic reaction.

Observation:

  • This report details the first documented instance of anaphylaxis attributed to the ingestion of marking nut.
  • The patient experienced a severe allergic response following consumption of food containing Semecarpus anacardium.
  • Contact hypersensitivity is a known effect, but systemic anaphylaxis is a novel observation.

Findings:

  • Ingestion of marking nut (Semecarpus anacardium) can lead to systemic anaphylaxis.
  • This represents a significant expansion of the known clinical manifestations of Semecarpus anacardium toxicity.
  • The study identifies a new potential trigger for severe food allergy.

Implications:

  • Clinicians should consider Semecarpus anacardium as a potential cause of anaphylaxis, especially in individuals consuming traditional Indian foods.
  • Further research is warranted to understand the allergenic mechanisms of marking nut.
  • Dietary awareness regarding Semecarpus anacardium is crucial for preventing severe allergic reactions.
