Allergen immunotherapy in polysensitized patient.

Area of Science:

• Allergy and Immunology
• Clinical Medicine

Background:

• Specific allergen immunotherapy (AIT) positively impacts allergic disease natural history.
• Increasing poly-sensitivity in allergy tests presents a challenge for AIT candidacy.
• Distinguishing true polysensitization from panallergen-induced cross-reactivity is crucial.

Purpose of the Study:

• To differentiate true polysensitization from cross-reactivity in allergic patients.
• To guide the appropriate use of allergen immunotherapy (AIT) in poly-sensitized individuals.

Main Methods:

• Review of Czech and Slovak long-term experience in allergy testing.
• Analysis of specific IgE testing and allergy skin tests.
• Evaluation of cross-reactivity patterns related to panallergens.

Main Results:

• Identification of criteria to distinguish true polysensitization from cross-reactivity.
• Clarification of AIT eligibility in complex allergic cases.
• Demonstration of the impact of accurate diagnosis on treatment decisions.

Conclusions:

• Accurate differentiation between polysensitization and cross-reactivity is essential for effective AIT.
• This distinction allows for appropriate AIT application in a broader patient group.
• Leveraging extensive regional experience enhances diagnostic accuracy in allergy immunotherapy.
