Summary
Corticosteroids can cause allergic reactions. This review examines their characteristics, diagnosis, and the immunological mechanisms behind these hypersensitivity responses.
Area of Science:
- Immunology
- Pharmacology
- Allergy and Clinical Immunology
Background:
- Corticosteroids are widely used for their anti-inflammatory and immunomodulatory properties.
- They treat diverse conditions, including allergic diseases.
- Hypersensitivity reactions to corticosteroids can occur.
Purpose of the Study:
- To review the epidemiology and clinical features of corticosteroid hypersensitivity.
- To discuss diagnostic challenges associated with these reactions.
- To analyze proposed immunological mechanisms, including cross-reactivity.
Main Methods:
- Literature review of epidemiological and clinical studies.
- Analysis of case reports and immunological data.
- Synthesis of proposed mechanisms of hypersensitivity.
Main Results:
- Corticosteroid hypersensitivity presents with varied clinical manifestations.
- Diagnostic approaches include skin testing and in vitro assays.
- Immunological mechanisms involve both immediate and delayed reactions, with potential cross-reactivity among corticosteroids.
Conclusions:
- Hypersensitivity to corticosteroids is an under-recognized clinical issue.
- Understanding the mechanisms is crucial for accurate diagnosis and management.
- Further research is needed to elucidate cross-reactivity patterns and improve diagnostic strategies.

01:30Hypersensitivities
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...

01:30Drug Toxicity: Allergic Reactions
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 exposure to a...
01:27Allergic 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...
01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

01:30Allergic 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),...
