Exam 2 - Feline Allergic Skin Disease Flashcards
what common clinical signs are associated with feline pruritus?
excessive grooming!!!!
scratching, licking, etc
what is the big question to consider when presented with a pruritic cat?
what is the pattern
what are feline cutaneous reaction patterns?
commonly recognized lesions - skin response to an inflammatory stimuli that is NOT a definitive diagnosis
what are 4 examples of feline cutaneous reaction patterns?
- pruritic dermatitis - head, neck, pinnal pruritus (cervicofacial dermatitis)
- self-induced alopecia
- miliary dermatitis
- eosinophilic skin lesions - indolent ulcers, eosinophilic plaques, & eosinophilic granulomas
what is this called?
fur mowing
what should you rule out when presented with a pruritic cat?
rule out parasites & infection first
what is the minimum database for working up a pruritic cat?
skin scrapings
impression cytology
woods lamp, DTM, & PCR
T/F: any feline cutaneous reaction pattern can be flea allergy dermatitis
true
if a cat’s face is only affected with skin lesions, what do you think is going on?
food allergy!!!
how is feline atopic skin syndrome diagnosed?
clinical diagnosis based on exclusion of other pruritic skin diseases - no test to diagnose atopic dermatitis
positive serum or skin testing can support the diagnosis & guide therapy
what factors affect feline atopic skin syndrome?
immune system dysregulation
genetics & environment
epidermal barrier dysfunction
what is the major cytokine you would think is involved in feline atopic skin syndrome?
IL-31
can you use cytopoint in cats?
NO - could kill them
can you use apoquel in cats? should you?
yes - maybe not, not labelled for cats & they metabolize it faster, so you have to dose them twice a day and at a higher dose
how long does it take for a cat to clear a bacterial skin infection?
3-4 weeks
what is the most common allergy seen in cats?
flea allergy dermatitis
why not use turkey or duck as a novel protein in a diet trial for a pruritic cat?
they are closely related to chicken which is likely something the cat has eaten before
need something novel
T/F: in feline food allergies, the protein is the most common offender & not the grain
true
why is blood testing for allergens better than the injections in cats?
cats suck at making hives
T/F: we don’t know if cats with atopy have a faulty epidermal barrier
true
what glucocorticoid would you use in an itchy cat? why?
prednisolone - need the active form of the drug because they’re lacking in glucoronidation
this pattern distribution represents what feline cutaneous reaction pattern?
cervicofacial dermatitis
this pattern distribution represents what feline cutaneous reaction pattern?
self-induced alopecia - will get to wherever they can reach
this pattern distribution represents what feline cutaneous reaction pattern?
miliary dermatitis - easier to feel rather than see, little crusted papules
this pattern distribution represents what feline cutaneous reaction pattern?
eosinophilic skin lesions - back of the caudal thighs, ventral chin, & oral lesions
this pattern distribution represents what feline cutaneous reaction pattern?
eosinophilic skin lesions
this pattern distribution represents what feline cutaneous reaction pattern?
eosinophilic plaques - very pruritic
what is the lesion in the picture? what differential are you considering?
eosinophilic plaque - bacterial pyoderma
this pattern distribution represents what feline cutaneous reaction pattern?
indolent ulcer - can be unilateral or bilateral & the animal may or may not have clinical signs
what part of the flea life cycle are you targeting in therapy?
adult - need an adulticidal
do we see evidence of fleas with cats?
not often - cats are great hunters
