Basophil Activation Test for Investigation of IgE-Mediated Mechanisms in Drug Hypersensitivity
Published on: September 16, 2011
Summary
Contact dermatitis cases linked to lip salve identified phenyl salicylate and geraniol as allergens. One allergen, phenyl salicylate, was removed from the product formulation to prevent further reactions.
Area of Science:
- Dermatology
- Allergology
- Cosmetic Science
Background:
- Contact dermatitis is a common skin reaction.
- Lip salves are frequently used cosmetic products.
- Identifying specific allergens in topical formulations is crucial for patient management.
Observation:
- Six cases of perioral contact dermatitis were reported.
- The dermatitis was associated with the use of a specific lip salve.
- A characteristic ring-like rash around the mouth was observed in affected individuals.
Findings:
- Five patients exhibited allergic contact dermatitis to phenyl salicylate.
- One patient showed an allergic reaction to geraniol, a fragrance component.
- Phenyl salicylate was identified as a significant contact allergen in this lip salve formulation.
Implications:
- Removal of phenyl salicylate from the lip salve formulation is recommended.
- This case series highlights the importance of fragrance and preservative allergen screening in cosmetics.
- Clinicians should consider lip salve ingredients when diagnosing perioral dermatitis.

Overview
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...
01:30Allergic 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),...
01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...
01:19Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
