Summary
Immediate hypersensitivity to corticosteroids is rare but potentially fatal. This case highlights confirmed corticosteroid allergy in an asthmatic patient, emphasizing the need for careful diagnosis and alternative treatment strategies.
Area of Science:
- Clinical immunology
- Allergy and immunology
- Pharmacology
Background:
- Corticosteroids are vital anti-inflammatory and immunomodulatory agents.
- Immediate hypersensitivity to corticosteroids is uncommon but clinically significant.
- Sulfite intolerance is a known sensitivity, but corticosteroid allergy requires specific diagnostic consideration.
Observation:
- A 38-year-old male with asthma and sulfite intolerance developed urticaria after antibiotic and corticosteroid (Group A) ingestion.
- Allergy workup confirmed beta-lactam and Group A corticosteroid allergy.
- Positive intradermal skin tests with methylprednisolone and hydrocortisone confirmed immediate hypersensitivity.
Findings:
- Skin tests were negative for corticosteroids in Group B and C.
- Betamethasone administration was well-tolerated, indicating a viable alternative treatment.
- The diagnostic process involved clinical history and specific skin testing across different corticosteroid groups.
Implications:
- Corticosteroid allergy, though rare, can be life-threatening, particularly in patients with asthma or aspirin intolerance.
- Accurate diagnosis through clinical evaluation and group-specific skin testing is crucial.
- Identifying specific corticosteroid allergens enables the selection of safe alternative therapies.
