Q

what is thought to be the cause of acute pancreatitis in cats and what are some risk factors for disease?

A

we dont know what causes it

no association with breed, gender, diet, obesity, or drugs

being middle aged to older, bacterial infection more common but can be secondary, IBD, cholangitis, hepatic lipidosis secondary

Q

briefly explain the pathophys of acute pancreatitis

A

pancreatic enzymes like trypsinogen inside the acinar cells become activated INSIDE the pancreas. Net result is intracellular digestive enzyme activation

Q

you do a CBC/chem on Duchess Snugglepaws McFlooferton who you think could have pancreatitis. What results do you expect?

A

neutrophilia +/- left shift, hemoconcentration, thrombocytopenia (can cause DIC so make sure you investigate this!!)

increased liver enzymes, hyper or hypo albuminemia, azotemia, hypocholesterolemia, hypocalcemia

Q

true or false: serum lipase and amylase can be used to reliably diagnose pancreatitis in dogs.

A

false! they are not sensitive enough! lipase is normal in 60% of cases and amylase is normal in 50% of cases! they are also not specific enough! both can increase with hepatic or GI disease OR increased due to decreased renal clearance

Q

you decide to do abdominal radiographs on Duchess Snugglepaws McFlooferton, who you suspect has pancreatitis. what are some things you suspect to see? if you see nothing on radiographs, then what?

A

decreased abdominal contrast/abdominal effusion, “signal loop” of duodenum.

if we see nothing this is still helpful because we can rule out other diseases!

Q

you decide to do an abdominal ultrasound on Duchess Snugglepaws McFlooferton, who you think has pancreatitis. what do you expect to see?

A

hypoechoic pancreas

BUT this is HIGHLY dependent on operator skill and experience, can miss it!

Q

Duchess Snugglepaws McFlooferton’s owner is a human nurse and is well versed in medical terminology, and she asks you if you could do an aspirate of the pancreas. What do you say to her?

A

there are some risks, you’re poking an already angry pancreas, and even if it comes back negative/no inflammation, this doesn’t mean there is no pancreatitis present because the inflammation can be localized

17
Q

what is technically the gold standard for diagnosing acute pancreatitis but is almost never done?

A

a pancreatic biopsy usually via ex lap (incisional)

18
Q

Duchess Snugglepaws McFlooferton’s radiographs and cPL test comes back suggestive for acute pancreatitis. What treatment options will you offer?

A

first tier: fluids, antiemetics, analgesia, nutrition

second tier: antibiotics, plasma

third tier: surgery

19
Q

why are fluids indicated for pancreatitis?

A

a perfused pancreas is a happy pancreas! fluids keeps the microcirculation open and helps limit progression of disease. You can also supplement electrolytes like potassium.

20
Q

what antiemetic options are there for Duchess Snugglepaws McFlooferton? (pancreatitis)

A

maropitant, metoclopramide, ondansetron

21
Q

what is the proper way to provide nutrition for Duchess Snugglepaws McFlooferton? (panreatitis)

A

early feeding is beneficial (historically it was thought that fasting was the way to go)

ideally voluntary intake, but dont hesitate to place a feeding tube

use a low fat diet like royal canin GN or purina OM

22
Q

what is specific about giving cats with pancreatitis nutrition?

A

palatability is more important than fat content, and make sure to consider other concurrent disease like IBD, cholangiohepatitis, hepatic lipidosis, when choosing a diet

23
Q

why is plasma indicated for treatment of acute pancreatitis?

A

it provides alpha 2 macroglobulin, coagulation factors, and albumin

it is controversial and studies have mixed results, but you should consider it minaly in cases of DIC

24
Q

the brand new drug, Fuzapladib, has become recently available and could potentially help treat pancreatitis. how does it work?

A

it blocks neutrophil activation, adhesion, and migration, and may limit progression of pancreatitis and associated systemic inflammation in dogs

25
Q

chronic pancreatitis in dogs shows concurrent evidence of _____

A

endocrine and/or exocrine pancreatis function, like diabetes or EPI

26
Q

with chronic pancreatitis in dogs, what concurrent diseases can they have because of this?

A

hepatic lipidosis, cholangitis/cholangiohepatitis, diabetes mellitus, IBD, CKD

27
Q

what is the cause of EPI in dogs and cats?

A

in dogs, it can be from chronic pancreatitis, or it can be from pancreatic acinar atrophy (like in GSD)

in cats, it is ALWAYS from chronic pancreatitis

28
Q

a dog named Fido Fluffernutter comes to you with chronic diarrhea paired with polyphagia. when you ask what his diarrhea looks like, the owner describes it as yellow and “fluffy”, like a slushie. what is your number 1ddx?

A

EPI

29
Q

how will you confirm EPI in Fido Fluffernutter?

A

a TLI test: highly sensitive and specific

if the result is low, you have EPI

30
Q

Fido Fluffernutter’s TLI comes back really low and you diagnose him with EPI. What treatment will you offer?

A

dried porcine pancreatic extract as a replacement therapy for the digestive enzymes, it’s a powder that you can sprinkle on your food

recommend a high quality diet

consider cobalamin supplementation
