Workup and Clinical Assessment for Allergen Immunotherapy Candidates

Area of Science:

• Allergy and Immunology
• Clinical Medicine

Background:

• Allergen immunotherapy (AIT) effectively treats allergies but has contraindications.
• Assessing AIT candidates for underlying conditions is crucial but lacks standardized guidelines.
• Physicians often rely on clinical experience due to limited research on pre-AIT evaluations.

Purpose of the Study:

• To propose a practical approach for evaluating AIT candidates for contraindicating conditions.
• To address the clinical, ethical, and legal concerns regarding pre-AIT workups.
• To guide allergists in assessing patients without a prior medical history before initiating AIT.

Main Methods:

• Review of existing guidelines and expert opinions on AIT contraindications.
• Discussion of a case-by-case approach to patient evaluation.
• Categorization of potential workup tests into mandatory and optional.

Main Results:

• No universally accepted guidelines exist for evaluating AIT candidates.
• A targeted workup, based on clinical suspicion, is more effective than a blanket approach.
• Specific conditions like neoplastic, autoimmune, cardiovascular diseases, immunodeficiencies, and pregnancy require careful consideration.

Conclusions:

• Pre-AIT medical evaluations should be individualized and based on patient history and clinical examination.
• A thorough, yet judicious, assessment helps identify potential contraindications, ensuring safe and effective AIT.
• The decision for further investigations must be clinically justified to avoid unnecessary testing.
