Hypersensitivities

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: 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),...

Allergic Drug Reactions

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...

Immunological Memory

Immunological Memory

Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...

Summary

Many children can outgrow peanut and tree nut allergies, with oral food challenges being the definitive test for resolution. Research is ongoing into new tolerance induction methods.

Area of Science:

Allergy and Immunology
Clinical Nutrition
Pediatric Medicine

Background:

Peanut and tree nut allergies have risen significantly in Western countries.
Food-allergic reactions cause over half of fatal anaphylaxis cases.
Previously considered permanent, some young patients now outgrow peanut (20%) and tree nut (10%) allergies.

Purpose of the Study:

To review current understanding of peanut and tree nut allergy resolution.
To discuss predictors of allergy outgrowing and methods for determining resolution.
To explore emerging strategies for inducing tolerance.

Main Methods:

Literature review of studies on peanut and tree nut allergy prevalence, resolution, and treatment.
Analysis of factors associated with tolerance, including T regulatory cells and IgE levels.
Evaluation of diagnostic methods like skin prick testing, IgE analysis, and oral food challenges.

Main Results:

Resolution of peanut and tree nut allergies is possible in a subset of young patients.
Allergen-specific IgE and skin prick tests are unreliable for predicting resolution.
Oral food challenge is the gold standard for confirming allergy resolution in a clinical setting.

Conclusions:

While predictors are lacking, oral food challenges confirm resolution of peanut and tree nut allergies.
Oral immunotherapy and sublingual immunotherapy are experimental but promising for inducing long-term tolerance.
Recurrence of peanut allergy is possible, necessitating careful monitoring.
