DOCTORS PANEL QUESTIONS
&
ANSWERS
We wish to thank all the
members on our Doctors Panel, for giving us their time answering PBCers
questions. We greatly appreciate all they do for us.

QUESTION 1
I read very little about varices in the PBC
digest. Is this common?
Does the bleeding from varices occur through the
rectum or mouth?
If rectal, how would a person distinguish from the
varices or polyps?
ANSWER 1
"Varices" (I assuem you
man varicose veins between the systemic and portal circulations) occur in
farily advanced cirrhosis. They can occur
in subjects with PBC when cirrhosis (scar
formation and nodules in the liver) has develops. If the pressure in
the portal circulation (the circulation of the gut that then goes to the
liver) increases because of cirrhosis, varicose veins can form in the stomach
and esophagus (gastric and esophageal varices)
and rectum (hemorrhoids). Gastric and esophageal
varices can rupture and bleed massively. The subject
will generally vomit blood or "coffee grounds," which is partially digested
blood. Esophageal varcies can be diagnosed
by upper endoscopy (insertion of a fiber optic
tube into the esophagus and stomach) and rectal
varices by flexible
sigmoidoscoy or colonoscopy (insertion of a fiber
optic tube in the rectum). Sometimes rectal
varices can be felt on manual examination.
Rectal varices are very different from polyps;
if they bleed, they generally bleed more than polyps bleed.
QUESTION 2
Can people have Autoimmune
Cholangiopathy and never really progress?
Please explain.
ANSWER 2
Since "autoimmune
cholangiopathy" is a very ill-defined condition
(if it really is a condition), I cannot answer this question.
QUESTION 3
How should I proceed to be proactive in my approach
to PBC diagnosis and treatment?
ANSWER 3
You should work closely with a good doctor who is
familiar with the condition. You should keep a very positive attitude
as, in many or most cases, having PBC should not significantly
effect your daily life. You should realize
that, if it becomes necessary, liver transplanation
is available as a "life insurance policy" for most individuals with PBC.
QUESTION 4
How do I know if my fatigue is PBC-related or just "normal?" I feel
tired much of the time. Why is fatigue so common in PBC, and not the
same in other liver diseases?
ANSWER 4
Nobody really can answer this question. Fatigue may occur in any subject
with chronic liver disease, not only PBC. Subjects with other chronic
diseases also often suffer from fatigue. Nobody knows why. It
is not clear why some subjects with PBC are sometimes more fatigued than
others. In subjects with chronic liver disease, it is not clear what
is "normal" fatigue (i.e. fatiuge anyone may suffer
from working too hard and being too busy) and what may result from the disease.
QUESTION 5
Please explain the difference in definition and treatment between Autoimmune
Hepatitis and PBC?
Since PBC is thought to be an autoimmune disease is AIH another distinct
disease?
How can you have both? Does treatment differ?
ANSWER 5
Autoimmune hepatitis (AIH) and PBC are distinct diseases. In
the vast majority of cases, PBC and autoimmune hepatitis can be readily
distinguished by an experienced doctor. PBC affects the bile ducts
within the liver and AIH primarily affects the
hepatocytes, or major cell type in the liver.
While some doctors sometimres refer to "overlap"
syndromes between PBC and AIH, this is an ill-defined condition and, if there
is "overlap," it occurs infrequently. Treatments are different.
For AIH, treatment is generally immunsupression
(prednisone or a similar drug with or without
azathioprine). For PBC, the treatment is
ursodiol.
QUESTION 6
Is it possible to have cholestatic
LFTs, neg. AMA ,
a negative biopsy, a mother with PBC and not go on to develop PBC or like
conditions with bile duct damage? Please explain.
ANSWER 6
First of all, "LFTs" are a terrible thing
to call serum ALT, AST and alkaline phosphatase
activities. They do not really tell you about "liver function."
Regarding your question, there are many causes of
"cholestatic LFTs" (I
assume you mean elevated serum alkaline phosphatase
activity). In most cases, elevated serum alkaline
phosphatase actvity does
not indicate PBC but another problem. The problem may not always be
diagnosed by liver biopsy. If someone's mother has PBC, it is still
very unlikely that she will have PBC (however, probably a bit more likely
that for an unrelated person).
