Cirrhosis of the
liver
Question: Hello Dr. Richards,
I have written to you a couple of times and your answers have been so
helpful in my coping with Cushing's disease.
Well, my Bichon Muffin who has Cushing's disease was diagnosed this
week with cirrhosis of the liver. She had been trembling and
I knew something
was wrong. Her Cushing's has been under control with the use
of anipryl,
so her vet did another physical and a bile acid test. She had
a physical
just this March and her albumin number was 3.2; however this time,
we were at
2.9 (below normal). Her bile acid test was below 20 on the pre,
but 35 on
the post. So we went on to an ultra sound and this is where the
cirrhosis
showed up. Her adrenal gland was perfect. I found this
doctor via the
Internet at the University of Missouri, at their liver institute, who
studies
currently are on cirrhosis and I called him. I was so afraid
that maybe I had
chosen the wrong medication for Cushing's disease, so I asked him if
excess
cortisol could cause cirrhois and he said no. That made me feel
a lot better.
She is now going to have a needle guided biopsy ultra sound.
Also without my
knowledge, I found that the men who mow by lawn have been putting down
Roundup. I called animal poison control and they told me they
did not
think this could be the reason but opened up a case history on her.
I know
I may never find the reason, but also I can't find anything in detail
about
cirrhosis in dogs on the Internet. My own vet is still in the
process
of consulting and studying and wants to get everything together before
we
start doing whatever we have to do. He did change her over to
the L/D diet
and she has been on silymarin for her Cushing's anyway. She has
never lost
any fur or had hind leg weakness from her Cushing's and still to look
at her,
she looks normal for a 13 year old dog, never mind one who has Cushing's
disease.
No change in eating and water consumption is normal. She
is not
jaundice in any way. I guess my big question to you is
what can I expect from
cirrhosis, and can you direct me to any detailed information (books,
the
Internet, etc.) on this disease.
By the way, this is a wonderful service that you offer and I use your
site very often whenever I have a question. Your site has pulled
me
through many anxious moments.
Thank you,
Cathy
Answer: Cathy-
Cirrhosis of the liver can occur as the end result of several liver
diseases, which may be why it is hard to find information on this
condition as a separate entity. Cirrhosis can occur in copper storage
diseases of
the liver, as the end result of idiopathic chronic hepatitis (also
called
chronic active hepatitis, chronic canine inflammatory hepatic disease
and probably other names), as a breed related disorder (several terrier
breeds, Dobermans, Labs, cockers and standard poodles), due to anti-seizure
medications and possibly due to carprofen and oxibendazole (a
dewormer). It is sometimes the end result of infectious illnesses,
especially
leptospirosis and infectious canine hepatitis (pretty rare now).
Of these conditions, the one that usually shows up without much warning
is the idiopathic chronic hepatitis. This condition can sometimes go
on
for long periods of time with no really obvious clinical signs and
affected
patients may have markedly decreased liver size and function when the
condition finally causes clinical signs. Even at this point it is often
possible to help make patients feel better for some time, though. The
usual recommendations are to use a low to moderate protein diet to
try to
decrease the liver's work load, use metronidazole or neomycin orally
if
there are signs of central nervous system disturbance, to give
lactulose for the same reason, to consider the use of cholchicine,
ursodiol
(Actigal Rx), SAMe (Denosyl SD-4 Rx), copper chelating agents if necessary
and
to provide general supportive care, such as gastrointestinal protects
if
GI ulceration occurs, fluid therapy if there is dehydration, Vitamin
K if
blood clotting problems occur, and possibly Vitamin E as an
anti-oxidant. In liver disease, at least if copper toxicosis is possible,
it is best
to avoid Vitamin C supplementation as it can make the copper toxicity
worse.
As the diseases mentioned above progress, they slowly destroy liver
cells, resulting in scarring and an increase in fibrosis in the liver,
or
cirrhosis. Some patients live for extended periods of time even
after
it is clear that they have reached the stage that liver cirrhosis is
occurring. I can think of two or three patients who lived for two or
more years in our practice and seemed to have a good quality of life
during
that time. Other patients don't do as well but it is still worth trying
to
control the secondary problems and to make the liver's job as easy
as
possible and then to see what happens.
It can be pretty hard to go back at at the time that there is cirrhosis
and to figure out why it occurred, so when the liver disease is discovered
at this stage, it may not be possible to give you information on the
underlying disease and thus the diagnosis of cirrhosis, rather than
a
more specific diagnosis.
I hope that Muffin is one of the patients who does do well. It may be
hard to find information on cirrhosis itself, but if you want
to read good
descriptions of liver disease that might lead to it, there are pretty
good chapters in several of the veterinary textbooks, such as the "Textbook
of Veterinary Internal Medicine" by Ettinger and Feldman and the "Handbook
of Small Animal Practice" by Morgan. There was a good review
of liver
disease in one of the Clinics of North America (I can't remember exactly
when),
if your vet subscribes to this journal.

Cirrhosis of the
liver
Question: Dear Dr.: Last weekend my 10yr old ibezan hound
had a distended abdomen. After doing
x-rays, lab work (all her liver enzymes were elevated) an ultrasound
and an ekg, my vet
diagnosed cirrhosis of the liver. He felt a biopsy was not needed.
He kept her in the hospital for
several days on iv fluids antibiotics and diurectics. He sent her home
on lasix, amoxicillin and a
kd diet. Wouldn't an l/d diet be better for her, and doesn't she need
K+ when she is on lasix? I
am considering taking her to a specialist, is there such a thing as
an internist for dogs, and do
you think this would be a good idea? I do love her so.
Thanks in advance, A.
Answer: A.-
There are specialists for dogs. In this case, a board certified internal
medicine specialist would probably be the best choice. I strongly support
referral when the client desires it because specialists usually have diagnostic
capabilities, such as being able to do ultrasound guided biopsies, that
general practices do not have. If there is not a board certified specialist
close to you, then considering going to one of the veterinary schools is
a good idea.
I think that Hill's would recommended l/d over k/d in most cases but
k/d actually does meet the requirements for low protein, but high quality,
protein that is the strongest dietary recommendation in pets with liver
diseases other than hepatic lipidosis. The newer diet, l/d, does have some
other ingredients, such as the essential fatty acids, that may be more
beneficial in liver disease.
Most of the time in dogs potassium depletion does not seem to be a problem
with the use of furosemide (Lasix Rx). I do not routinely advise potassium
supplementation when using furosemide, either. This is a possible side
effect, though, and there is no harm in supplementing potassium that I
am aware of.
It is always reasonable to ask your vet about referral to a specialist.
He or she may not feel that this is necessary but if you desire a second
opinion this is the best way to ensure getting a knowledgeable one that
I know of.
