Study Notes
Allergic Skin Disease Overview
- Allergy is a hypersensitivity response to allergens, commonly causing pruritus in dogs and cats.
- Allergic skin disease (ASD) is multifactorial, influenced by genetic, environmental, and immunological factors.
Key Triggers of Allergic Skin Disease
- Environmental Allergens:
- Canine: Environmental atopic dermatitis
- Feline: Feline atopic skin syndrome (FASS)
- Food Allergens:
- Canine: Food-induced atopic dermatitis (food allergy)
- Feline: Feline food allergy (FFA)
- Ectoparasites:
- Flea allergic dermatitis
- Insect bite hypersensitivity
- Mite hypersensitivity, particularly Sarcoptes
- Contact Allergens
- Micro-organisms:
- Malassezia hypersensitivity
- Drugs
Hypersensitivity Responses
- Type I hypersensitivity is the most common, involving IgE-mediated degranulation of mast cells, leading to tissue inflammation.
- Requires sensitization through repeated allergen exposure; subsequent exposure results in an excessive immunological response.
Common Forms of Allergic Skin Disease
- Canine Atopic Dermatitis (CAD):
- Chronic, relapsing condition presenting with pruritus and inflammation.
- Traditionally linked with IgE antibodies to environmental allergens.
- Feline Atopic Syndrome:
- Includes FASS and FFA, exhibiting similar clinical features as CAD.
Learning Objectives for ASD Sessions
- Describe history and clinical signs of ASD through prior immunological knowledge.
- Choose appropriate diagnostic tests, understanding the pros and cons of serological and intradermal tests.
- Select treatments considering acute and chronic needs, factoring cost, practicality, and efficacy.
Session Plan Highlights
- Lectures on pathogenesis and clinical signs.
- Group work on diagnostic tests for food-induced and environmental atopy.
- Discussion of treatment options.
- Case studies for practical application.
