What is Allergic Reaction? Over reaction to common environment substance –Mite 、 pollen 、 hair 、 fungi –Soybean 、 wheat 、 milk 、 pork etal. Over reaction to common environment substance –Mite 、 pollen 、 hair 、 fungi –Soybean 、 wheat 、 milk 、 pork etal.

What Causes for Allergies? Type I acute anaphylactic reaction –IgE - degranulation of Mast cell –Mediator released –Atopy 、 Dermatitis 、 Asthma Type I acute anaphylactic reaction –IgE - degranulation of Mast cell –Mediator released –Atopy 、 Dermatitis 、 Asthma

IgE - Degranulation of Mast Cells Cell-bound form IgE

Mediator Released

Atopic Canine Atopic Dermatitis (AD) –inhalent or GI-intake? Age of the onset: 1-3 years Clinical presentation: pruritus 、 erythema 、 chewing 、 licking 、 salivary staining Atopic Dermatitis (AD) –inhalent or GI-intake? Age of the onset: 1-3 years Clinical presentation: pruritus 、 erythema 、 chewing 、 licking 、 salivary staining

Clinical presentation

Health Care of Atopic Pet Rule out other disease Avoid second infection Pet’s serum specific IgE profile Food design based on allergen result immunotherapy Rule out other disease Avoid second infection Pet’s serum specific IgE profile Food design based on allergen result immunotherapy

Traditional Diagnosis Clinical signs and history Skin test Serological test –ELISA/ –RAST(radioallergosorbent test) Clinical signs and history Skin test Serological test –ELISA/ –RAST(radioallergosorbent test)

What defect about skin test? Shaved the hair Dangerous to pet Food allergen unable 8-10 allergen could be tested at one time Shaved the hair Dangerous to pet Food allergen unable 8-10 allergen could be tested at one time

What defect about traditional serological test? Too many false negative results –Sensitivity is not enough Too many false positive results –Specificity is not enough Score is confused – Signal range is too small Too many false negative results –Sensitivity is not enough Too many false positive results –Specificity is not enough Score is confused – Signal range is too small
