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...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

2.4K
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...

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

1.7K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and...

Hypersensitivities01:30

Hypersensitivities

7.3K
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

280
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,...

    Area of Science:

    • Allergy and Immunology
    • Immunotherapy Research

    Background:

    • Conventional immunotherapy is effective but has drawbacks like systemic reactions, time, and cost.
    • Modifying allergens is a key strategy to enhance immunotherapy safety and efficacy.

    Purpose of the Study:

    • To review different approaches for modifying allergens to improve immunotherapy.
    • To highlight the most promising strategies for allergen modification.

    Main Methods:

    • Review of existing literature on allergen modification techniques.
    • Analysis of three major approaches: impeding release, suppressing IgE, and reducing allergenicity.

    Main Results:

    • Impeding allergen release (e.g., alum precipitation) showed limited success.
    • Suppressing IgE production and inducing tolerance has not been successful in humans.
    • Reducing allergenicity while retaining immunogenicity is the most promising approach.

    Conclusions:

    • Modified allergens, particularly polymerized allergens, allergoids, and glutaraldehyde-treated, tyrosine-adsorbed allergens, offer improved safety and efficacy.
    • Further research into allergen modification holds significant promise for advancing immunotherapy.
