Allergen immunotherapy

Area of Science:

• Immunology
• Allergy and Clinical Immunology

Background:

• Allergen immunotherapy (AIT) is an effective treatment for allergic rhinitis, allergic asthma, and stinging insect hypersensitivity.
• Patient selection for AIT involves a comprehensive evaluation, including allergy testing and discussion of goals, risks, benefits, and commitment.
• Factors like symptom severity, medication use, and patient preferences influence the decision for AIT in allergic rhinitis and asthma.

Purpose of the Study:

• To review the indications, contraindications, and patient selection criteria for AIT.
• To detail the administration, safety, and efficacy of AIT for allergens other than foods.
• To provide guidance for physicians on prescribing and administering AIT.

Main Methods:

• Review of current literature and clinical guidelines on allergen immunotherapy.
• Analysis of factors influencing AIT decision-making in patients with allergic rhinitis and asthma.
• Discussion of safety protocols and management of anaphylaxis during AIT.

Main Results:

• AIT is a potentially disease-modifying therapy for specific allergic conditions.
• Careful patient selection and thorough discussion are crucial for successful AIT.
• AIT administration, particularly subcutaneous immunotherapy, requires medical supervision due to the risk of anaphylaxis.

Conclusions:

• Allergen immunotherapy is a valuable treatment option when indicated and administered correctly.
• Physician training and appropriate clinical settings are essential for safe AIT.
• This review focuses on AIT for non-food allergens, with food immunotherapy discussed separately.
