Allergic Reactions: Anaphylaxis

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),...

Background:

Olive pollen is a major cause of seasonal respiratory allergies in Mediterranean countries.
Olive fruit and oil allergies, including contact dermatitis, are also documented.
Knowledge of olive allergens is growing, with increasing scientific publications.

Purpose of the Study:

To review current knowledge on olive allergens.
To discuss allergen extraction, production, and characterization methodologies.
To summarize studies on olive pollen and fruit allergens.

Main Methods:

Literature review of scientific studies on olive allergens.
Analysis of methodologies for allergen extraction and production.
Evaluation of physicochemical and immunological characterization techniques.
Revision of studies on olive pollen and fruit allergen analysis.

Main Results:

Twelve allergens identified in olive pollen.
One allergen identified in olive fruit.
Established methodologies for olive allergen characterization exist.

Conclusions:

Olive allergens are significant contributors to allergic diseases.
Further research is needed to fully understand olive allergens and develop effective treatments.
This review consolidates current knowledge, providing a basis for future studies.
