Update on equine allergies

Area of Science:

• Veterinary Dermatology
• Equine Allergy Research
• Immunopathology

Background:

• Horses suffer from various allergic skin and respiratory conditions, including pruritic skin diseases, urticaria, allergic rhinoconjunctivitis, and reactive airway disease.
• Allergen-specific immunoglobulin E (IgE) is identified in affected horses, and allergen-specific immunotherapy is a common treatment approach.
• Insect hypersensitivity is the most recognized atopic condition in horses, yet achieving successful treatment outcomes with immunotherapy is difficult.

Purpose of the Study:

• To review current understanding of allergic disease pathogenesis in horses.
• To discuss recent findings in human and canine allergy research.
• To explore the relevance of human and canine data to equine allergic disorders.

Main Methods:

• Literature review focusing on equine allergic diseases.
• Inclusion of recent research on human and canine allergy pathogenesis.
• Comparative analysis of findings across species.

Main Results:

• Allergic conditions in horses share similarities with those in humans and dogs.
• Understanding pathogenesis is key to improving treatment efficacy.
• Further research is needed to refine immunotherapy for equine allergies.

Conclusions:

• Equine allergic diseases require further investigation into their pathogenesis.
• Comparative immunology offers insights into equine conditions.
• Developing effective allergen-specific immunotherapy for horses remains an ongoing challenge.
