Overview
Allergic rhinitis caused by insect stings, particularly bee venom, involves an immune response to allergens like melittin, leading to symptoms such as nasal congestion, sneezing, and itching. 1Diagnosis
Identification of exposure history to insect stings.
Presence of specific IgE antibodies to insect venom components (e.g., melittin).
Clinical symptoms consistent with allergic rhinitis post-sting exposure.
Skin prick tests or specific IgE blood tests for confirmation. 1Management
First-line treatments: Avoidance of insect stings through protective measures and venom immunotherapy (VIT) for severe cases.
Adjunctive treatments: Antihistamines for symptom relief; corticosteroids for severe inflammation. 1Special Populations
Pregnancy: Limited evidence; focus on avoidance and symptomatic treatment with caution. 1
Pediatrics: Venom immunotherapy can be considered in severe cases, tailored to age-appropriate dosing. 1
Elderly: Increased vigilance for systemic reactions; individualized treatment plans recommended. 1
Comorbidities: Consider potential interactions with existing medications; adjust treatment accordingly. 1Key Recommendations
Identify and quantify specific IgE antibodies to insect venom allergens for diagnosis. (Evidence: Moderate 1)
Implement venom immunotherapy for patients with a history of severe allergic reactions to insect stings. (Evidence: Moderate 1)
Use antihistamines and corticosteroids for symptomatic relief in allergic rhinitis post-insect sting exposure. (Evidence: Expert opinion 1)References
