Component-resolved diagnostics in pet allergy: Current perspectives and future directions

Area of Science:

• Allergy and Immunology
• Environmental Health

Background:

• Furry mammals are significant sources of pet allergens.
• Increasing global prevalence of sensitization to animal dander.
• Characterization of various mammalian allergens and availability of component-resolved diagnostics (CRD).

Purpose of the Study:

• To review mammalian aeroallergens, focusing on cat, dog, and horse allergens.
• To discuss the role of CRD in refining allergy diagnosis and immunotherapy.
• To highlight CRD's utility in predicting asthma risk and severity.

Main Methods:

• Literature review of mammalian aeroallergens and component-resolved diagnostics.
• Focus on allergens from domestic animals like cats, dogs, and horses.
• Discussion of CRD's application in clinical diagnostics and immunotherapy.

Main Results:

• Mammalian allergens, particularly from cats, dogs, and horses, are prevalent.
• Component-resolved diagnostics (CRD) enhance diagnostic accuracy.
• CRD serves as a valuable marker for predicting asthma risk and severity.

Conclusions:

• CRD refines the diagnosis of allergies to furry animal allergens.
• Component-resolved diagnostics (CRD) are crucial for personalized allergy management.
• Future implications of CRD in understanding and treating furry animal allergies are significant.
