Allergen-specific immunotherapy in food anaphylaxis

Area of Science:

• Allergy and Immunology
• Immunotherapy Research
• Food Allergy Management

Background:

• Specific immunotherapy (SIT) protocols for food allergens are emerging, initially focusing on oral allergy syndrome due to pollen cross-reactivity.
• Existing studies suggest benefits of SIT for oral allergy syndrome patients.
• Management of true food anaphylaxis, such as peanut allergy, is more complex and often relies on individualized protocols.

Purpose of the Study:

• To review the current landscape of specific immunotherapy for food allergens.
• To highlight the complexities and potential of SIT in managing true food anaphylaxis.
• To emphasize the role of SIT in providing durable protection against severe allergic reactions.

Main Methods:

• Review of published studies on specific immunotherapy for food allergies.
• Analysis of SIT protocols for oral allergy syndrome and true anaphylaxis.
• Evaluation of therapeutic strategies and outcomes in defined cases.

Main Results:

• SIT protocols are recently established for nutritional allergens, particularly for oral allergy syndrome.
• Significant research supports the benefits of SIT in patients with oral allergy syndrome.
• For true anaphylaxis (e.g., peanut allergy), SIT is complex and based on individual protocols, lacking extensive controlled studies.

Conclusions:

• Specific immunotherapy is a promising approach for durable protection against life-threatening risks from accidental food allergen ingestion.
• While SIT for oral allergy syndrome is well-studied, its application in true anaphylaxis requires tailored strategies.
• In select cases, SIT offers a viable therapeutic option for severe food allergies.
