Overview
Dermatosis caused by Hymenoptera stings encompasses allergic reactions ranging from localized skin reactions to severe systemic anaphylaxis. These reactions are mediated by hypersensitivity to venom components.Diagnosis
Clinical history: History of sting exposure and allergic reaction 1.
Skin testing: Specific IgE testing for venom allergens 1.
Grading: Based on severity (localized urticaria to anaphylaxis) 1.Management
First-line treatment:
- Epinephrine: For anaphylaxis (auto-injectors with 0.3-0.5 mg for adults) 1.
- Antihistamines: For symptomatic relief of urticaria and pruritus 1.
Adjunctive treatments:
- Corticosteroids: For systemic reactions to reduce inflammation 1.
- Rush venom immunotherapy: Rapid desensitization protocol achieving maintenance dose of 100 micrograms of venom in 3 days 1.Special Populations
No specific data provided: Abstracts do not cover pregnancy, pediatrics, elderly, or comorbidities directly 1.Key Recommendations
Implement rush venom immunotherapy for patients with severe systemic reactions to hymenoptera stings, achieving maintenance dose safely within 3 days 1 (Evidence: Strong).
Use epinephrine as first-line treatment for anaphylactic reactions following Hymenoptera stings 1 (Evidence: Strong).
Consider corticosteroids adjunctively in managing systemic reactions to mitigate inflammation 1 (Evidence: Moderate).References
