Summary
Allergic contact dermatitis (ACD) in children is often caused by nickel sulfate. Patch testing is crucial for diagnosis, with higher relevance in younger children, indicating age shouldn't prevent testing.
Area of Science:
- Dermatology
- Pediatric Allergy
Background:
- Allergic contact dermatitis (ACD) is a prevalent condition in children.
- Patch testing is the gold standard for identifying contact allergens in suspected ACD cases.
- Current data on common allergens in pediatric ACD is limited.
Purpose of the Study:
- To identify common allergens responsible for ACD in children and adolescents.
- To evaluate the clinical relevance of patch test results in this age group.
Main Methods:
- Patch testing was performed using the Indian Standard Series.
- Additional allergens were included based on patient history.
- Seventy-four pediatric patients with suspected ACD were recruited; 70 were analyzed.
Main Results:
- Over half of the patients (54.3%) showed one or more positive patch test reactions.
- Nickel sulfate was the most frequently identified allergen.
- Clinically relevant reactions were observed in 78.94% of positive cases.
- Positive patch test relevance was significantly higher in younger children (3-9 years) than adolescents (10-19 years) (P=.030).
Conclusions:
- ACD is a significant health issue impacting children's quality of life.
- Patch testing is effective in diagnosing ACD in children and adolescents.
- Age should not be a barrier to performing patch testing for ACD diagnosis.

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...

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...

01:30Allergic Reactions: Anaphylaxis
110
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,...
