3

What will you find on PE in a stable, uncomplicated canine diabetic?

They may be relatively normal and cataracts are common

4

How do cataracts develop?

Unremarkable CBC, hyperglycemia, mild elevation of liver enzymes (ALP > ALT), hypercholesterolemia, and hypertriglyceridemia

6

What will you find on urinalysis in a stable, uncomplicated canine diabetic?

Glucosuria and variable USG

7

Why do 24% of diabetic dogs have bacterial UTIs with no evidence of pyuria?

Glucose may be a substrate for bacteria. Since the immune system is compromized due to the diabetic state, it allows for the bacteria to proliferate

8

insulin - they are 'type 1' diabetics

9

In order to treat stable and uncomplicated canine diabetics, we must provide exogenous sources. What are the exogenous insulin types that can be given to dogs?

FALSE

11

0.25-0.5 units/kg subcutaneously every 12 hours

When should a recheck occur after diagnosis of stable and uncomplicated diabetes in the dog?

In about 1-2 weeks - want to recheck clinical signs, BG curve, and urine

16

Type 2 diabetes - there is a relative insulin deficiency

18

What is an important risk factor for feline diabetes?

obesity

19

What condition is more problematic in the feline diabetic versus the canine diabetic?

stress hyperglycemia - it affects diagnosis and monitoring

20

What complication is more common in the feline diabetic?

diabetic neuropathy

21

Is dietary management more important in the canine or feline diabetic?

the feline

22

What are the goals of therapy in a diabetic feline?

Eliminate clinical signs, reduce risk of complications, and promote diabetic remission if possible

23

What are the first choices of exogenous insulin in the stable feline diabetic?

PZI or glargine

24

What is the initial insulin dosage in the stable feline diabetic?

1 Unit/cat SC BID

25

Aside from insulin therapy, what is important in initial therapy of the stable feline diabetic?

Implement dietary management

26

What oral hypoglycemic dug is an option for feline diabetics?

Glipizide - only successful in 1/3 of cats

27

When is the use of Glipizide indicated in feline diabetic patients?

When the owners are unwilling or unable to give insulin

28

high protein, low-carbohydrate diets

29

What is different between cats and dogs about insulin administration and feeding?
