| More on Compensated Liver disease
The signs of compensated cirrhosis include a large, hardened liver,
small, star-shaped vessels (spider angiomata) on the skin of the upper
torso, blotchy redness on the palms (palmar erythema), whitened nails, thin
silky hair, loss of body hair, prominent veins on the abdomen (abdominal
collateral veins), irregular or absent menstruation in pre-menopausal women,
and small testes and enlarged, sometimes painful breasts (gynecomastia) in
men. The signs of decompensated cirrhosis include all the above except that
the liver may be shrunken and there may be swelling of the legs (edema),
accumulation of fluid in the abdomen (ascites), bleeding from veins in the
esophagus (varices), and mental confusion (hepatic encephalopathy).
Most chronic liver disease damages the liver over time by forming scar in
the liver that replaces normal liver tissue. When there is enough scar, we
call this cirrhosis. Cirrhosis is an advanced form of scarring or liver
damage. However, even a cirrhotic or badly scarred liver can often still
perform all the functions that a liver needs to do and in fact, it often
continue to perform these functions quite well even for decades. This is
because we are all given excess liver capacity which allows the liver to
function well even if a significant amount of the liver is damaged. When a
liver is diseased or cirrhotic but is still functioning well we say this is
compensated liver disease.
This is a critical distinction because many people with hepatitis C will
have cirrhosis but have no signs of liver failure. We call this compensated
cirrhosis. Many of these people will be stable for years and many will be
candidates for therapy. They typically do not have to be considered for
liver transplant unless the liver starts to fail or their disease “decompensates”.
Signs of decompensated liver disease include jaundice, marked fluid
retention in the abdomen (ascites), episodic confusion or a specific type of
gastro-intestinal bleeding.
I do want to say that when the liver starts to fail with chronic liver
disease, it almost never happens suddenly, unless some one is drinking
heavily or gets another insult to the liver like hepatitis A. People with
chronic liver disease often feel they will feel fine one day and then be
close to death the next and this is not the way things work. In fact,
typically, liver specialists can start to see signs of liver failure in
tests months or years before the patients themselves notice them.

Cirrhosis--A Liver Problem
What is cirrhosis?
If the liver is damaged, scars can form. When the liver has a lot of scar
tissue, blood will not easily flow through it. Cirrhosis is the name for a
scarred liver. (Say this: sir-oh-sis.) Cirrhosis keeps the liver from
working the way it should. A liver with cirrhosis can't make enough of some
proteins your body needs. It can't remove enough harmful toxins (poisons)
from your blood. It can't help your blood to clot normally.
What causes cirrhosis?
Cirrhosis is most often caused by heavy use of alcohol or by an infection
(usually with the hepatitis B or hepatitis C virus). Some medicines and
chemicals can hurt the liver. Diseases that weaken the immune system and
some inherited diseases can damage the liver.
What problems can cirrhosis cause?
a.. People with cirrhosis bruise easily because their blood does not clot
the right way. When these people have a cut, it may bleed for a long time.
b.. Blood vessels around the esophagus (in the throat) and the intestines
can stretch and become thin. If these blood vessels burst open, the result
is a dangerous amount of bleeding.
c.. Because the liver is not working right, toxins build up in the blood.
They can hurt your brain. People with cirrhosis are also more likely to get
liver cancer.
d.. If the cirrhosis is so bad that the liver stops working, the only
treatment is a liver transplant.
e.. Cirrhosis can cause death. According to the American Liver
Foundation, cirrhosis is the 8th leading cause of death in the United
States.
Can any of these problems be prevented?
If you have cirrhosis, it may be possible to avoid, or at least slow
down, many of the problems caused by cirrhosis. Here are some things you can
do to feel better for a longer time:
a.. Don't drink any amount of alcohol of any kind.
b.. Ask your doctor about getting important vaccines, like hepatitis A
vaccine, hepatitis B vaccine, pneumococcal vaccine (to help prevent
pneumonia) and influenza vaccine (to help prevent the flu). Hepatitis A
infection is very dangerous for people with liver damage.
c.. Tell your doctor about every medicine, vitamin and herbal remedy you
are taking. Many medicines and herbal remedies are dangerous to people with
cirrhosis.
d.. Follow a low-fat, "heart-smart" diet. Foods that are low in fat, oil,
and salt are good for your liver and your heart.
e.. Work with your doctor to set up a health care routine. In addition to
your regular doctor visits, you will need tests at least once a year to
check your liver and your risk for bleeding problems.

Treatment of Chronic Hepatitis C in Decompensated Cirrhotics
Gregory T. Everson,
M.D. University of Colorado School of Medicine, Denver, CO
May 20 2002
There are two main reasons to treat patients with
decompensated cirrhosis. First, effective treatment could clear the virus
prior to transplantation and avoid post-transplant recurrence of hepatitis
C. Second, viral eradication may halt disease progression and possibly
avoid the need for transplantation.
Currently, hepatitis C is the leading indication for
liver transplantation in the United States and the proportion of patients
with end stage liver disease due to hepatitis C is increasing. Many
studies
have demonstrated that patients who are HCV RNA positive prior to
transplant will experience post-transplant recurrence of infection and
many of these may require retransplantation due to progressive hepatitis
and cirrhosis. Post-transplant treatment of recurrent hepatitis C is
problematic due to effects of immunosuppression and intolerance to side
effects of interferon-based treatment. For these reasons, pre-transplant
treatment and viral eradication is potentially the most effective strategy
in limiting the impact of post-transplant recurrence of hepatitis C.
Combination therapy with standard interferons plus
ribavirin in clinically stable populations without advanced liver disease
clears hepatitis C RNA in 50% to 60% on treatment, and clearance is
sustained in approximately 40%. Results with peginterferon plus ribavirin
are even more encouraging with on-treatment clearance rates of 70 to 80%
and sustained viral clearance of approximately 55%.
Most studies, but not all, have indicated that rates of
viral clearance are lower in cirrhotic patients, due, in part, to dose
reductions and side effects of treatment. Nonetheless, many cirrhotic
patients experience both on-treatment and sustained response. Those that
clear virus may experience reduction or abolition of liver inflammation,
arrest of disease progression, and even resolution of fibrosis. The
published experience has mainly focused on compensated cirrhotics as
interferon-based treatment has generally been considered to be
contraindicated in those with clinical evidence of advanced liver disease.
Colorado Experience
The expanding numbers of patients with hepatitis C on
the waiting list coupled with the problems of post transplant recurrence
of disease, stimulated us to consider treatment of decompensated
cirrhotics. Our treatment protocol was dubbed LADR (low-accelerating dose
regimen) to indicated initiation of therapy at half doses of IFN and
ribavirin followed by dose increases based upon patient tolerance. G-CSF
and erythropoietin analogue, were used to treat cytopenias. Efficacy was
defined by clearance of HCV RNA and tolerance was assessed by occurrence
of side effects, adjustments in dose of interferon and ribavirin,
frequency of dropouts from treatment, and use of G-CSF or erythropoeitin
to correct cytopenias.
Our initial group of 86 candidates for treatment was
male-predominant with 50% reporting significant past alcohol use or abuse.
The population was enriched in hepatitis C genotype 1 and 86% had either
biopsy-proven or obvious clinical signs of cirrhosis. The remaining 14%
had bridging fibrosis on biopsy or other features suggesting advanced
disease (spider telangiectasia (a vascular lesion formed by dilatation of
a group of small blood vessels), thrombocytopenia). Sixty three percent had experienced clinical decompensation with either variceal hemorrhage,
ascites, spontaneous bacterial peritonitis, or encephalopathy. Two-thirds
of patients who had upper endoscopy, had esophageal varices.
Treatment was difficult in this patient population.
There were 21 dropouts, mainly for side effects of fatigue, neuropsychiatric symptoms, or cytopenias. The rate of serious
inter-current illness was what one might expect in this population. 28%
required G-CSF and only 1 required erythropoeitin.
Eleven of the 86 patients elected not to enroll in the
trial. Of the remaining 75, 21 dropped from treatment due to side effects,
29 were nonresponders. 25 cleared RNA on treatment. Of the 25 on-treatment
responders, 12 relapsed. RNA was positive by 3 months in all who relapsed.
The other 13 remain RNA negative but 4 were still on treatment and 3
others were followed for less than 6 months post-treatment. Overall, the
on-treatment rate of clearance of RNA was 29% for all eligible patients,
33% for enrolled patients, and 46% for those who enrolled and did not drop
from treatment. Responders and nonresponders were similar in terms of age,
gender distribution, % with obvious cirrhosis, or frequency of clinical
decompensation.
In this initial experience, two factors seemed to be
most important in determining response. Nonresponders were enriched in
genotype 1 and a lower percentage of responders were able to achieve full
doses of treatment for at least 3 months. The effect of dose on response
was observed primarily in genotype 1.
Of the 57 patients with genotype 1, 23 never achieved
full dose for at least 3 months. Only 2 of these 23 patients cleared RNA
on treatment and neither sustained this response. The only sustained responses in patients with genotype 1 occurred in those who were able to
take at least 6 months of full dose treatment. In contrast to patients
with genotype 1, those with other genotypes cleared RNA more frequently
and there was less dependency upon dose. In fact, 2 sustained responders,
who were treated for 12 months, never received full dose therapy for over
3 months.
Outcome in LADR Patients who were Transplanted.
Twenty six patients treated by LADR underwent
transplantation. Six were sustained responders prior to transplantation
and none have experienced post-transplant recurrence. Seven had
on-treatment response but relapsed prior to transplant. One was retreated,
became HCV RNA negative, was transplanted, and remains HCV RNA negative
for one year post-transplant. The other 6 relapsers were not retreated,
underwent transplant, and all recurred. All thirteen
non responders have post-transplant recurrence of
hepatitis C.
Implications for Living Donor Liver Transplantation.
Twenty eight patients infected with HCV have received
LDLT (living donor liver
transplantation) at our center between 8/97 - 4/2001.
Fourteen received no treatment and remained HCV positive pre- and
post-transplant. Two of the remaining twelve were non responders to
interferon monotherapy and recurred post-transplant. The 12 remaining
patients received either standard combination therapy or LADR. Four of the
12 were complete responders on- treatment (33%) and remain free of HCV 6
months or more post-transplant.
Summary
HCV RNA can be cleared in at least 33% of cirrhotics
with advanced liver disease using the LADR protocol. Best response is
achieved in non-1 genotypes and in genotype 1 patients able to take full
dose treatment for at least 3 months. Relapse, after discontinuation of
treatment, is more frequent in this group of patients but retreatment of
relapse prior to transplantation may clear virus and prevent
post-transplant recurrence. Those who experience sustained response will
not relapse post-transplant. LADR treatment may be well-suited for
application in the setting of LDL T where the timing of transplantation in
relation to treatment can be fixed. Treatment is difficult in this
population, dropouts are common, serious complications can occur, and G-CSF
or erythropoeitin may be needed.
Conclusions
LADR may be warranted in decompensated cirrhotics, but
genotype 1 patients who become RNA negative should be maintained on
treatment until time of transplantation. In addition, if treatment is withdrawn in a responder, HCV RNA should be monitored for relapse and
consideration of reinstitution of therapy. We also speculate that
clearance or suppression of hepatitis C RNA will slow disease progression,
improves hepatic function, and possibly reduces the need for
transplantation.
