The sting

Area of Science:

• Allergy and Immunology
• Toxicology
• Public Health

Background:

• Anaphylactic reactions to insect stings affect approximately 0.4% of the general population.
• Individuals with a family history of beekeeping have a higher prevalence, up to 20%, of experiencing these reactions.
• Systemic reactions can escalate in severity with repeated stings, and insect stings cause an estimated four to five deaths annually in Canada.

Purpose of the Study:

• To evaluate the effectiveness of venom immunotherapy for treating insect sting allergies.
• To assess the utility of various diagnostic tests in managing hymenoptera allergies.
• To provide insights into the epidemiology and clinical course of anaphylaxis due to insect stings.

Main Methods:

• Review of efficacy data for venom immunotherapy.
• Analysis of diagnostic methods including skin tests, in vitro assessment of venom-specific IgE (allergy antibody) and IgG (blocking antibody).
• Evaluation of leukocyte histamine release assays as a diagnostic and monitoring tool.

Main Results:

• Venom immunotherapy demonstrates a high efficacy rate of approximately 95%.
• Skin tests and in vitro assessments of IgE and IgG antibodies are valuable for diagnosing hymenoptera allergy.
• Leukocyte histamine release assays serve as effective monitors for treatment effectiveness.

Conclusions:

• Venom immunotherapy is a highly effective treatment for insect sting-induced anaphylaxis.
• Allergy testing, including specific IgE and IgG antibody measurements, is crucial for diagnosis and monitoring treatment.
• Understanding the epidemiology and utilizing appropriate diagnostic tools can improve patient outcomes for hymenoptera allergies.
