Summary
Chronic urticaria can be triggered by nickel in food. Dietary nickel restriction led to complete healing in a patient with persistent hives, confirmed by allergy tests.
Area of Science:
- Allergy and Immunology
- Dermatology
- Clinical Nutrition
Background:
- Chronic urticaria is a common dermatological condition characterized by recurrent hives.
- Identifying specific triggers is crucial for effective management of chronic urticaria.
Observation:
- A patient with chronic urticaria presented with persistent symptoms.
- Allergy testing revealed both type I and type IV sensitization to nickel.
- An oral challenge test with nickel was positive.
Findings:
- The patient's chronic urticaria was directly linked to dietary nickel intake.
- A strict nickel-restrictive diet resulted in complete and long-standing remission of symptoms.
Implications:
- Dietary nickel restriction is a viable and effective treatment strategy for select patients with chronic urticaria.
- This case highlights the importance of considering food allergens, specifically nickel, in the etiology of chronic urticaria.
- Further research into nickel allergy and its role in chronic urticaria is warranted.
