12h fasted serum TLI
33
What measures of TLI indicate EPI in dogs? In cats?
Dogs <2.5ug/L | Cats <8.5ug/L
34
How can an animal's feces aid in EPI diagnosis?
Fecal elastase is produced exclusively in the pancreas (<10ug/g is diagnostic)
35
Do EPI animals usually have weight loss with a good or poor appetite ?
Usually good
36
What nutritional deficiency is seen in 82% of EPI cases?
Cobalamin deficiency
37
Why is cobalamin deficient in dogs with EPI?
Lack of pancreatic proteases to release cobalamin from transport proteins
38
What are fat soluble vitamins that may become deficient with EPI?
Vit A, D, E, K
39
Does fat absorption ever return to normal in EPI cases?
No
40
What antibiotic therapy can treat SIBO if there is a poor response to enzyme treatment?
Metronidazole or tylosin
41
Why are gastric blockers used concurrently to treat EPI/
Reduce stomach acidity (incr. pH) to prevent enzyme supps from being inactivated
42
What is the prognosis of EPI?
20% euthanized d/t expense of treatment | 60% show good response to initial treatment
43
What cobalamin level is assoc. w/a shorter survival time of EPI?
<100ng/L
44
Develops as a result of pancreatic auto-digestion
Pancreatitis
45
What mechanisms are in place to prevent pancreatic autodigestion?
Trypsin inhibitor, alpha macroglobulin, enzymes are stored as inactive
46
What breeds are most predisposed to pancreatitis?
Mini Schnauzers and mini poodles
47
What usually causes pancreatitis?
Dietary indiscretion
48
What endocrine disorders can predispose to pancreatitis?
DM, hyperadrenocorticism, hypothyroidism
49
Why might melena result from pancreatitis?
Duodenal inflammation 2* to pancreatitis can cause GI bleeding
50
Why might hematochezia result from pancreatitis?
Proximity of an inflamed pancreas to colon causes trauma to the colon
51
What is "prayer position"?
Rear end up, forelimbs extended in front (looks like stretching)
52
Why might pancreatitis produce a thrombocytopenia?
2* to PLT consumption d/t severe inflammation
53
What type of diet is indicated for canine pancreatitis?
Low fat diet
54
Do cats require a low-fat diet or a period of NPO for pancreatitis?
No
55
What other condition commonly accompanies a pancreatitis cats?
DKA
56
How long should a pancreatitis dog be NPO and why?
24h, fasting will rest the pancreas

58
Why will an inflamed pancreas appear hypoechoic on ultrasound?
Edema

Why will an EPI dog lose weight despite having a ravenous appetite?
Lose ability to digest fat and protein
