Fatigue and Liver Disease
In this article, which is excerpted from my book “ Dr. Melissa
Palmer’s Guide to Hepatitis and Liver Disease” I will discuss one of the
most common and debilitating symptoms among individuals with liver
disease - fatigue. Fatigue is a symptom characterized by a diminished
ability to exert oneself, usually associated with a feeling of being
tired, bored, weak, and/or irritable. It is universal to all types of
liver diseases, and does not necessarily correlate with the severity of
liver disease. In fact, fatigue may be just as debilitating to an
individual in the early stages of liver disease, as in an individual
with advanced cirrhosis.
In some people, fatigue begins several years after the diagnosis of
liver disease has been made. In others, it is the primary reason for
seeking medical attention in the first place. Oftentimes, multiple
visits are made to a variety of different types of doctors in search of
a cause of fatigue before it is connected with liver disease. Some
people even seek psychiatric evaluation since depression often
accompanies fatigue.
Fatigue may occur at any time of day, but it is most common in the
morning. Often, little more than an hour after awakening, a person may
already feel the exhaustion of having worked an entire day. Others
describe weakness and lack of energy throughout the whole day. Their
usual “pep” is now gone. Even little tasks become more trying, and
around 3:00 P.M. they simply must lie down to take a nap.
Fatigue can be caused by the liver disease itself, from other
disorders- such as a thyroid disease or vitamin deficiencies- often
associated with liver disease, or from medication used to treat the
liver disease - such as interferon. Thus, the successful treatment of
fatigue can be multifactorial, and a challenge. The patient’s doctor
must carefully look at all of the factors possibly contributing to his
or her feeling of fatigue, as some factors can be corrected easily.
Anemia is a common cause of fatigue. The primary source of anemia
should be carefully sought, as there are many different potential
causes. Iron deficiency anemia may be due to blood loss from internal
bleeding. Thus, an extensive gastrointestinal evaluation may need to be
done. Simply taking iron supplements, however, is not always a wise
move, and may, in fact, be dangerous. Both iron deficiency and iron
overload may both cause fatigue. Excessive iron in the body of a liver
patient can be extremely dangerous. In excess, iron is toxic to the
liver and can lead to cirrhosis, liver failure and liver cancer.
Furthermore, there is growing evidence that even mildly increased (or
sometimes even normal) amounts of iron may cause or enhance the amount
of injury to the liver in the presence of other liver diseases. This
applies especially to individuals with alcoholic liver disease and
chronic hepatitis C. In fact, iron overload is commonly seen in people
with alcoholic liver disease and chronic hepatitis C, and has been found
to worsen the outcome and to decrease the responsiveness to treatment.
Liver scarring and liver cell damage are directly related to the iron
content of the liver cell. Since a person’s body is unable to eliminate
an overabundance of iron, neither iron supplements nor vitamins
containing iron should be included in the diet of an individual with
liver disease, unless it has been determined that there is an iron
deficiency.
Interferon and/or ribavirin - medications used to treat chronic
hepatitis C, may also result in anemia. Interferon has been shown to
suppress red blood cell production, and ribavirin may cause red blood
cells to burst open and be destroyed– hemolysis. In fact, more than half
of patients on interferon and ribavirin combination therapy have been
shown to decrease their red blood cell count (hemoglobin) and become
anemic. Erythropoietin is a hormone made by predominately by the
kidneys. This hormone stimulates the bone marrow to produce red blood
cells. Recombinant human erythropoietin was first cloned in 1985, and
subsequently became FDA approved in 1989 - Epoetin alfa, Procrit.
Preliminary studies demonstrate increases in hemoglobin levels following
the subcutaneous administration of Epoetin alfa for anemia due to
interferon/ribavirin therapy.
Vitamin B 12 and folate are both crucial to the formation of red
blood cells. Therefore, a deficiency of these vitamins often leads to
anemia and associated fatigue. This explains why individuals with liver
disease who suffer from excessive fatigue, often ask about vitamin B12
injections. However, their expectation that such an injection will
provide an “extra boost ” of energy is misguided. Since vitamin B12 is
commonly found in animal food products such as meat, fish, milk and
eggs, a vitamin B12 deficiency is a very uncommon cause of fatigue in
individuals with liver disease. A few exceptions must be made to this
statement. One exception applies to individuals with alcoholic liver
disease for whom the bulk of nutrients are obtained from alcohol. A
vitamin B12 deficiency may develop among these individuals. Furthermore,
since alcohol interferes with the absorption of vitamin B12, a vitamin
B12 deficiency may develop if a person consumes an excessive amount of
alcohol even if he or she maintains a well-balanced diet. A vitamin B 12
deficiency may also occur in individuals with chronic liver disease who
maintain a strict vegetarian diet for a long period of time, such as is
the case for those suffering with chronic encephalopathy. Finally, the
older a person is, the more likely a B12 deficiency is to develop. This
is because stomach acid is needed to absorb this vitamin from food, and,
as a person ages, the amount of acid in the stomach diminishes.
Therefore, individuals with liver disease who are over the age of sixty,
or individuals with liver disease who are chronically on medications
that block stomach acid - such as H2 blockers (for example Pepcid, Axid,
Tagamet, and Zantac) or proton-pump inhibitors (for example, Prilosec,
Nexium, Prevacid, Aciphex and Protonix) should be checked for a vitamin
B 12 deficiency. As with vitamin B12, a folate deficiency can also
produce anemia. In fact, vitamin B 12 must be present in order to
activate folate, which accounts for the fact that a deficiency of one
tends to simultaneously cause a deficiency of the other.
Thyroid disease commonly coexists with liver disease and may also
cause fatigue. Furthermore, thyroid abnormalities may occur while on
interferon therapy. People who are prone to autoimmune disorders are
more likely to develop a thyroid disorder than people without this
propensity. A patient may develop either a slow-functioning thyroid
(hypothyroidism) or a fast-functioning thyroid (hyperthyroidism).
Thyroid disorders are readily diagnosed by obtaining a thyroid profile
from blood tests. Both hypothyroidism and hyperthyroidism may be easily
treatable with thyroid medication. Thyroid abnormalities that develope
while an individual is on interferon commonly resolve after interferon
is discontinued.
People with liver disease often suffer from sleep disturbances which
is a common cause of fatigue. In fact, approximately thirty-five to
fifty percent of individuals with cirrhosis report having sleep-related
difficulties. Some people have trouble falling asleep, whereas others
have difficulty staying asleep. Many people complain of being tired all
day, yet awake all night. Others complain of erratic sleeping habits
characterized by days of excessive sleep (hypersomnia) alternating with
days of lack of sleep (insomnia). Still others state that they
experience delays of their usual bedtimes and wake-up times. For most
people suffering from these sleep disorders, the sleep they do get is
not refreshing. And, all of these forms of sleep disturbances may cause
fatigue.
The cause of sleeping disorders in individuals with liver disease is
unclear, but most likely relates to alterations in the body’s production
of melatonin (a substance produced by the pineal gland and is involved
in the sleep cycle). Sometimes, sleep disturbances stem from medications
used in the treatment of liver disease. For example, interferon,
ribavirin, prednisone and propanolol are all associated with insomnia.
Also, caffeine, nicotine and alcohol consumption may contribute to
disturbed sleep habits and, as such, abstinence from these substances
will likely assist in the quest for a good night’s sleep. It should be
noted that sleep disturbances may be a sign of impending encephalopathy.
Treatment of sleeping disorders associated with liver disease
consists of both behavioral modification and medical management. People
should use their beds only for sleeping and never for other activities
such as reading, watching television, or eating. These activities should
be performed in other areas of the home. If an individual is unable to
fall asleep within twenty minutes of retiring, he or she should get out
of bed and read a book or perform another relaxing activity in another
room. Lights should be kept low and the television turned off. Only
after becoming tired should he or she return to bed. Also, people should
make an effort to wake up at the same time each day - regardless of the
amount of time he or she spent sleeping during the night. Although long
naps of two to three hours during the day are not recommended, a twenty-
to -thirty minute nap in the early afternoon, if it can be arranged, may
have a salutary effect. In no circumstances should alcohol should not be
used as a sleeping aide. Also, as most prescription and over-the-counter
sleeping pills are broken down by the liver, they should be avoided
unless their use in low doses and only for short periods of time, is
okayed by a liver specialist. Individuals with liver damage may be at
increased risk of prolonged sedative effects if these medications are
used at their generally prescribed dosages. Although used primarily for
the treatment of depression, selective serotonin re-uptake inhibitors (SSRIs)
such as Paxil, Zoloft, Celexa and Prozac are generally safe for most
individuals with liver disease, and may be of some benefit in treating
insomnia. Patients may also try Tylenol PM which contains benadryl prior
to retiring. Supplemental melatonin (1-2mg/day), taken a half hour
before going to bed, may also be helpful, although one must remember
that this supplement is not regulated by the FDA, and therefore the
amount of active ingredient per pill may vary from one bottle to the
next. The herb valerian has been purported to help sleep disorders.
However, this herb may cause serious liver disease and should always be
avoided.
Disorders of other organs, such as the heart or the brain, may also
cause or contribute to fatigue. These potential sources must be searched
for as well. Nutritional deficiencies, such as a lack of protein, as
well as disturbances in fluid and electrolyte balance, such as a low
sodium level, also contribute to exhaustion. Depression may lead to
fatigue and may require pharmacological control. All medications and
drugs that the patient is taking, both prescription, as well as
over-the-counter, must be reviewed by the patient’s physician. All
unnecessary ones should be eliminated, as some medications may also
cause fatigue. Excessive use of caffeine and lack of exercise are all
causes of fatigue which may be rectified via a lifestyle adjustment.
Finally, fatigue may be due to excessive and/or emotional stress. The
demands of a hectic job or harried home life may need to be modified, as
overwhelming stress may cause fatigue even in a person not suffering
from liver disease. Therefore, it is important that the patient’s family
and friends be aware of the increased needs that the patient suffering
from fatigue may have, and attempt to reduce any excessive or
unnecessary obligations or expectations that they may normally have of
the individual. Fatigue may be due to working too many hours. In fact,
some individuals suffer from the physical and mental effects of overwork
without even realizing.
If fatigue continues to persist after ruling out or correcting any
medical conditions, there are a few lifestyle changes that may be
helpful. For example, eating a healthy, low fat, well- balanced diet,
quitting smoking, refraining from all alcohol consumption, and
exercising daily, are all lifestyle changes that can have a beneficial
effect on fatigue. Drinking plenty of water and limitation of caffeine-
containing beverages to one- to -two cups per day are also recommended.
Any excess weight should be eliminated via a sound weight -reducing diet
(never lose more than one-to-two pounds per week). If possible, a
thirty-to-forty-minute daytime nap should be taken daily. This can help
rejuvenate a person with liver disease. In some cases, it may be
necessary to incorporate naps into the daily schedule. Often, a doctor’s
letter to the patient’s employer or supervisor may be in order. A person
with fatigue should feel free to ask his or her doctor for such a note.
Finally, one must remember that the treatment for fatigue cannot be
found in a pill. Be especially wary of any product that boasts,
“improved energy levels” on its label. Because the liver is in charge of
breaking down supplements and medications, more harm than good may
result from taking such a product. And, taking excessive amounts of
vitamins and minerals in an attempt to treat fatigue, especially vitamin
A, niacin or iron, can lead to worsening of liver disease. It is
essential that a person with liver disease consult a hepatologist prior
to taking supplements or any products that promise to cure fatigue.

Combatting HCV Fatigue
Alan Franciscus, Editor-in-Chief
and Fran Carey
http://www.hcvadvocate.org/news/newsLetter/2005/advocate0405.html#2
One of the most vivid memories I have from running a support group is
of a
woman who came to one of our support group meetings complaining of
fatigue
and depression. When we started our check-in, she expressed her
frustration
with the increased bouts of fatigue and the effect they were having
on her
life. This person's story is not that much different from others who
suffer
from fatigue, but I think that she was able to verbalize what many of
us go
through when we are fatigued. She is a single parent of two children.
In
order to put food on the table for her family and a roof over their
heads,
she is required to work long days and devote all of her precious
energy to
work. In the evening when she came home from work she would basically
collapse in front of the TV and would be unable to perform many of
the
functions needed to care for herself and her children. She became
isolated
and started to become depressed. In addition, she was unable to spend
the
necessary time to cook nutritious meals for herself and her children.
The
thought of exercise never occurred to her because she was so tired
all of
the time. For this person, life became a downward spiral and she saw
no way
out. Luckily, she came to a support group. Throughout the evening we
were
able to give her words of encouragement - she was not alone. We were
also
able to help her develop strategies to combat her fatigue. It was one
of
those incredible support group moments when you can start to see a
ray of
hope in someone's eye.
One of the most common symptoms that people with hepatitis C
experience is
fatigue. In fact, in one study 67% of people living with hepatitis C
reported fatigue as a symptom. Fatigue can range from mild to severe
and can
affect every area of life. Fatigue is a difficult symptom to quantify
since
it affects everyone differently. Some people with hepatitis C have
constant
fatigue while others may have fatigue cycles - sometimes they feel
energetic
and at other times they may feel so tired that they might not be able
to
perform basic daily functions, such as going to work, cleaning the
house or
joining in on social events.
It is important to keep in mind that when living with a chronic
illness such
as hepatitis C, energy management should be a top priority. When we
push
ourselves beyond our physical capacity, good judgment declines and
accidents
occur more frequently. In addition, when fatigue sets in, it is easy
to
become depressed or anxious about the future.
One of the most important strategies HCV positive people can adopt is
to
pace themselves and focus on techniques that may decrease the time
spent
doing certain activities and increase the amount of rest. As well,
activities should be prioritized according to their importance. If
the house
needs to be cleaned but you have a dinner date that evening, think
about
saving your energy for the evening and doing the house cleaning later
in the
week. You don't want to sacrifice needless energy at the expense of
more
important areas that will provide more of a balance in your life.
Causes of Fatigue
Fatigue can be caused by many factors including depression, anemia,
poor
diet, and lack of exercise, or by more serious ailments. It is
important to
talk with your medical provider if you are constantly fatigued. If
you feel
too tired to get out of bed for more than 24 hours or if you feel
confused,
dizzy, or have a problem waking up you should notify your health care
provider as soon as possible.
Medical Treatment for Fatigue
There are no approved medications to treat HCV-related fatigue, but
some
physicians are experimenting with a variety of drugs including
Ritalin and
Provigil. However, there is concern about the potential for abuse of
these
drugs - especially Ritalin since it is known to exacerbate substance
use
disorders. Studies are needed to determine the safety and
effectiveness of
these drugs in HCV positive individuals before they are used to treat
HCV-related fatigue.
Rest When Tired
It is important to rest when you get tired or when you have time.
Taking
short naps or rest periods during the day helps most people. Try not
to
sleep too much during the day because this could affect how well you
sleep
at night. Also, too much rest may make you even more tired so try to
find a
balance. Many people report that even just taking a few minutes to
close
down, mediate, pray, listen to music, reading or thinking about a
happy or
positive experience revitalizes them within a very short period of
time. If
you are having trouble sleeping or experience insomnia for more than
a few
days, talk to your medical provider about medicines to help you
sleep.
Plan Activity and Rest
Make a plan for the day, week, and month. Try to alternate activities
so
that you can balance the more difficult activities with the lighter
activities. People normally have certain times during the day or
night when
they have more energy. Save the more difficult tasks for when you are
more
likely to have the energy to perform them. Alternate the difficult
with the
easy tasks. Many people with hepatitis C and other chronic illnesses
report
that they have more energy in the evening. However, be careful that
you don't
overdo it or stay up too late since this can affect how well you
sleep in
the evening and how you will feel the next day.
Breathe
Incorrect breathing can lead to fatigue. When people are stressed out
or
fatigued they have a tendency to hold their breath. Try deep
breathing
exercises and concentrate on how the air goes in and out of your
body.
Massage
People report that massage helps to improve their energy and general
wellbeing. Try massage that uses techniques to encourage lymphatic
flow and
regain energy.
Acupuncture
Acupuncture is based on the idea that "qi" flows through the body in
channels called meridians; each organ system has a set of channels.
Acupuncture has been found to be helpful in relieving pain,
overcoming
addictions and in decreasing fatigue.
Exercise
It may seem counterintuitive, but regular exercise is one of the best
strategies for combating fatigue. Try to stay as active as possible
but don't
overdo it. Exercise comes in many forms and walking is one of the
best
exercises for relieving fatigue. Other forms of exercise include
Pilates,
yoga, swimming, light weight resistance or any other activity that
will
re-energize, but do not exercise to the point of becoming overly
fatigued.
Listen to your body and let it guide you. Start slowly with a 2- or
3-minute
walk and work your way up to 30 minutes of activity 5 days a week. It
is
also recommended that you check-in with your healthcare provider or
an
exercise physiologist to determine what level of activity is right
for you.
Diet
A healthy and nutritious diet based on the recommendations from
health
experts includes finding a balance between the quantities of food you
eat
with the amount of energy expended. Try to stay away from foods that
are
high in fat, sugar and sodium. Eat larger portions of fruits and
vegetables
and drink plenty of water. If possible, consult with a registered
dietician
or nutritionist.
Vitamins & Nutritional Supplement
A well-balanced diet should contain all the essential vitamins and
minerals
you need, but some people also take vitamin supplements. Taking a
megavitamin supplement may be harmful to the liver. Instead choose a
multi-vitamin supplement without iron that meets the daily
requirements.
Is It Important?
Ask yourself -is this task really necessary? Will the benefit
outweigh the
chance that you will become overly fatigued? There are many
alternatives to
common chores, such as to allow dishes to drip dry, to buy permanent
press
or fabrics that need little attention beyond laundering, and to use
frozen
or pre-cut vegetables instead of peeling and cutting.
Ask for Help
Don't be afraid to ask for help from family members or friends. Many
times
people are willing to help but may not want to interfere with your
life. It
never hurts to ask for help and you might be surprised to find that
your
family and friends will be more than happy to help you out. However,
you may
need to set limits so that it doesn't turn into a social exercise
that could
deplete your energy even more. If you have the resources available,
it might
be worth considering using a laundry or house cleaning service. The
key is
to simplify when possible.
Educate Family and Friends
Talk to your friends about what it means for you to be fatigued. Tell
them
that at times you may not be able to participate in social functions
or that
you may need to leave early because of fatigue. Learn to say "no" to
family
and friends who have unrealistic expectations of your energy level.
Organize
Staying organized is sometimes difficult, but it is the key for
putting to
use the limited energy one has. Have organized work centers, with all
supplies for each task stored together:
Keep all of the dry ingredients together including the mixing bowls;
keep
measuring tools together.
Put all of the cleaning supplies in a pail.
Store the can opener in the cupboard with the canned goods.
Store pots & pans near the stove.
Keep items within easy reach.
Avoid bending & reaching.
Eliminate unnecessary clutter.
Utilize organizing equipment such as revolving shelves, stacking
bins,
lazy-susans, etc.
Use wheels to transport: laundry cart, grocery basket, kitchen cart -
to
convey equipment & supplies in one trip. Load the cart with all the
goods
needed to set the table in one trip rather than several.
Use a wagon to transport groceries from car to the house, a cart to
transport the laundry, foods from the fridge to the counter, etc.
There are a lot of strategies that can help conserve energy and
reduce the
likelihood of fatigue induced injuries.
Try some of these simple tips:
Sit whenever possible. Use a tall stool at the sink to wash & prepare
food, use an adjustable ironing board as a work surface to sit at,
wipe down
the bathtub while still sitting in it, or use a shower stool and hand
held
shower for bathing.
Bathe before going to bed rather than in the morning. It takes less
energy
to put on nightwear since there is much less of it and you will have
less to
attend to in the morning. Always sit down while dressing and
undressing.
Use good posture and comfortable work heights. While standing, the
working
surface should be between waist & hips, while sitting, the surface
should be
no more than 3 inches below your elbows. Don't work at a low counter
that
causes you to bend over it. If the kitchen sink is low, place a pan
under
the dishpan to raise it closer to you.
Stand & sit with spine erect.
While you are working avoid stretching & bending. Keep most commonly
used
items within easy reach. Have long handles on the dustpan, bath
brush, and
use tongs to reach for something on the floor.
Work in a well-lighted environment that is at a comfortable
temperature
and has good ventilation. Wear supportive and comfortable shoes.
Use both hands for activities: setting the table, dusting, holding
pots.
Avoid stress and rushing. Frustration and irritation increase
fatigue.
Pace yourself; rushing leads to mistakes and accidents which then
require
extra energy to clean up or resolve, not to mention the potential for
injury.
Flare-ups of symptoms including fatigue are a common experience for
people
with HCV, which can drastically reduce your energy level and quality
of
life. Prepare for these times by storing dried, canned and frozen
foods/meals available for the times when you are not able to get to
the
store. Keep healthy snacks around the house and remember to eat small
frequent healthy meals. Skip unimportant tasks until a better time.
One of the most important strategies is to listen to your body. It is
important that you allow yourself to rest - pushing yourself
unnecessarily
could prolong your "flare-up" and make you feel worse. We all know
that
fatigue can cause depression and anxiety. Be prepared to indulge
yourself in
enjoyable activities that require little energy, such as meditating,
reading, watching a video, knitting, etc.
It is 'ok' to recognize that you are depressed. It is not healthy to
put a
positive spin on everything. Talk to family and friends - a friendly
ear can
help with anxiety and depression. Talk to professionals and seek
guidance.
Consider antidepressants - they can help with depression and energy.
One of
the most important strategies people living with hepatitis C can
adopt for
themselves is to join a support group.
Everyone experiences physical, mental and emotional changes
throughout their
lives and must adapt accordingly in order to safely maintain their
ability
to function. By practicing some of the above techniques you will
reduce your
risk for injuries and conserve your energy for the things in life
that are
most important to you.

Fatty Liver (Steatosis)
The Role of Steatosis
in the Progression of Chronic Hepatitis C
The relationship between HCV infection and steatosis is only
incompletely understood. In particular, it remains to be determined if
steatosis contributes to fibrosis, cirrhosis and ultimately to
hepatocellular carcinoma in individuals of hepatitis C virus infection.
In the March 2004 issue of The Journal of Hepatology, Dr. Francesco
Negro reviews what is currently known about the relationship between
hepatitis C infection and steatosis. Following is an edited version of
his commentary:
The progression of chronic hepatitis C towards cirrhosis is a
relentless process that may evolve over a period of decades. Several
factors may accelerate the rate of progression of liver fibrosis. Many
such factors, like male gender, prolonged alcohol abuse, co-infection
with the immunodeficiency virus, and obesity are now well recognized.
Others, like smoke and, possibly, some genetic polymorphisms, are
slowly being unravelled. In this context, the role played by the liver
steatosis as a disease modifier is suggested by an increasing number of
observations. Indeed, judging from the number of papers appeared on this
subject in recent years, steatosis is viewed as taking an increasingly
important role in many aspects of the hepatitis C virus (HCV) infection:
not only is it a diagnostic tool, but it may also significantly affect
both liver disease progression and response to antiviral treatment.
The diagnostic significance of steatosis in chronic hepatitis C was
proposed by early works, and later confirmed by several authors,
especially when it became clear that in many patients steatosis is a
histological hallmark of a direct toxic effect of HCV on the hepatocyte.
The evidence in favour of this comes from three observations: (1)
steatosis is more frequent and severe in patients infected with the
genotype 3 of HCV, suggesting the existence of specific ‘steatogenic’
sequences proper to this genotype; (2) the degree of fat infiltration
(especially in patients with the genotype 3) is correlated with the
level of HCV replication and protein expression, as measured both in
serum and in liver tissue, and 3) there is a close correlation, at least
in some patients (again, especially among patients with genotype 3)
between the disappearance of fat from the liver and the response to
antiviral therapy. In addition, the recurrence of HCV infection after an
initially successful treatment is accompanied by the reappearance of
steatosis.
That steatosis may correlate with fibrosis was first reported by
Hourigan et al. and then confirmed by several authors. However, recent
data suggest that this interaction is far more complex than previously
thought. Furthermore, it is less and less clear whether steatosis, that
may negatively influence liver disease progression, is due to HCV or
rather to concomitant conditions unrelated to the virus.
This issue is highly relevant, since understanding the histological
findings in pathogenetic terms has always been critical to proper
clinical management. So, we need to address the question: is steatosis
seen in chronic hepatitis C always due to HCV? And, if not, what are the
alternative mechanisms?
Several studies have provided good evidence in favour of the
existence of multiple factors independently underlying the fatty liver
in chronic hepatitis C. There is a ‘viral’ steatosis, i.e. directly
linked to HCV replication and mostly (but not exclusively) seen in
patients with genotype 3, that disappears upon successful antiviral
therapy.
Then, there is a so-called metabolic steatosis. The severity of fat
accumulation, in these cases, is proportional to the body mass index
(BMI), and is not responsive to antiviral therapy. Since obesity
increases with age and patients with genotype 3 are usually younger, the
metabolic type of steatosis is likely to affect more frequently patients
infected with non-3 genotypes. A third, well known component of
steatosis is alcohol abuse, but its contribution to the published series
is variable.
Diabetes and dyslipidemias may also contribute to steatosis of the
liver, and, finally, it is not unexpected that a variable proportion of
patients present with a mixed type steatosis, i.e. where viral and one
or more metabolic factors overlap. This is more likely to occur in
populations where overweight is highly prevalent and tends to affect
younger generations.
As said above, the association between steatosis and fibrosis in HCV
infection has been reported by many authors, including Patton and
co-workers. However, recent data seems to suggest a more complex
interaction. In one study, the association was denied, while in others
it seemed to hold true for only some patients' subgroups. As a matter of
fact, Patton et al. found an association between steatosis and fibrosis
only among patients with genotype 1 infection, i.e. those more likely to
suffer from metabolic steatosis, unresponsive to antiviral therapy.
A relationship between fatty liver and advanced fibrosis in genotype
3-infected patients is also suggested by other studies.
Dr. Negro concludes, “In conclusion, steatosis appears another factor
in affecting chronic hepatitis C progression. Whether it affects all
patients or only some subgroups of them, as a function of pathogenesis,
remains to be elucidated.”
“While prospective studies may address this question, measures aiming
at reducing risk factors of fatty liver seem now an established
acquisition in the clinical management of chronic hepatitis C patients.”

HEPATOLOGY WATCH®
Timely Information for Practicing Physicians
May 2001
Hepatitis C Virus (HCV)
Steatosis and chronic HCV infection. Steatosis is associated with
hepatic fibrosis and is a frequent finding in chronic HCV. Andrew
Clouston and coworkers studied 80 consecutive patients with untreated
chronic HCV for whom a liver biopsy was available for review to
determine the contribution of steatosis to fibrosis. Steatosis was
present in 56 patients (70%) and subsinusoidal fibrosis (SSF) and/or
central vein fibrosis was found in 52 of these patients. The fibrosis
had a chicken-wire appearance similar to that seen in steatohepatitis.
There was an association between more severe grades of steatosis and the
finding of SSF. In addition, the mean body mass index of patients with
focal or extensive SSF was higher (within the overweight range) than
that of patients without SSF. These findings demonstrate that the
occurrence of hepatic SSF during the course of chronic HCV infection is
correlated with steatosis, which in turn is associated with being
overweight. Thus, weight reduction may be an important therapeutic
maneuver for patients with chronic HCV. (Clouston AD, et al. J Hepatol
2001;34:314-320)

Fibrosis, Cirrhosis, and Steatosis
by Liz Highleyman
http://www.hepatitis-c-advocate.org/
Although many people with chronic hepatitis have few or no symptoms
and minimal liver disease progression, others will go on to develop
serious liver damage. This typically takes several years or decades. It
is estimated that 10-25% people with chronic hepatitis C will develop
cirrhosis after 20-30 years; for people with chronic hepatitis B
infection, the estimated rate is 20-30%.
Advanced liver damage may include fibrosis, cirrhosis, and steatosis.
These conditions can result from various types of liver injury, ranging
from viral infection to exposure to alcohol or other toxic substances.
The hepatitis C and B viruses (HCV and HBV) attack liver cells (hepatocytes),
where they multiply, or replicate. HCV and HBV cause liver inflammation
and kill liver cells (necrosis). Inflammation is an immune response to
infection or injury characterized by the infiltration of white blood
cells. The degree of liver inflammation is often reported in terms of
grades—from 0 to 4—or may be described as mild, moderate, or severe.
Fibrosis
Fibrosis refers to the development of fibrous scar tissue within the
liver and occurs when the normal processes involved in tissue repair get
out of control. The death of hepatocytes stimulates inflammatory cells
to release cytokines and other chemicals, which cause cells known as
fibroblasts to form around injured hepatocytes and synthesize fibrous
tissue, a process called fibrogenesis. Hepatic stellate cells have been
shown to play a key role in this process. Collagen, various
glycoproteins, and other components are deposited within the liver. This
connective tissue makes up the extracellular matrix (the structure
between cells) in healthy livers, but it proliferates excessively in
people with fibrosis. In addition, the liver’s normal ability to break
down matrix tissue (fibrolysis) may be impaired, leading to further
collagen build-up. Fibrosis can obstruct blood flow in the liver, lead
to further hepatocyte atrophy and death.
Bridging fibrosis occurs when new linking blood vessels form in an
attempt to restore circulation and fibrotic tissue extends beyond one
area (or portal) of the liver. Over time, fibrosis may progress to
cirrhosis.
Cirrhosis
Cirrhosis is a process in which the normal liver architecture
(structure) is altered by the formation of regenerative nodules
surrounded by scar tissue and fibrous membranes (septa), in an attempt
to repair the damaged organ. Liver cirrhosis may be classified by the
size of the nodules: micronodular (small nodules less than 3 mm in
diameter), macronodular (large nodules over 3 mm), or mixed. The
build-up of scar tissue usually progresses over time as long as the
source of liver injury remains. Eventually, abnormal cell proliferation
may lead to hepatocellular carcinoma, a type of liver cancer.
Compensated cirrhosis occurs when the liver is scarred but can still
work relatively normally; people with compensated cirrhosis typically
exhibit few or no serious symptoms. Decompensated cirrhosis occurs when
the liver is so damaged that it cannot function properly. The Child-Pugh
scoring system is used to grade the severity of cirrhosis on the basis
of symptoms.
Because the liver is responsible for so many important functions,
liver damage can have wide-ranging effects. Extensive scarring can
impair the circulation of blood through the liver, leading to portal
hypertension, or high blood pressure in the vessels that serve the
liver. This in turn can lead to the development of varices (stretched
and weakened blood vessels) in the esophagus and stomach, which may
burst and bleed. If the damaged liver is unable to synthesize adequate
albumin (a blood protein), fluid may accumulate in the abdomen, a
condition known as ascites. Inadequate production of clotting factor by
the liver can lead to prolonged bleeding and easy bruising. If the
liver’s filtering and processing ability is impaired, metabolic
by-products, hormones, and other substances may accumulate in the body.
Some people with decompensated cirrhosis experience jaundice (yellowing
of the skin and whites of the eyes), dark urine, and pale-colored stools
as bilirubin levels increase. The build-up of bile acids in the body can
cause pruritis (itching). An accumulation of estrogen can lead to spider
angiomas (clusters of dilated blood vessels in the skin) and
gynecomastia (breast enlargement in men). The build-up of toxic
substances such as ammonia can affect the brain causing hepatic
encephalopathy, characterized by mental impairment, confusion, lethargy,
personality changes, mood swings, and even coma. In the most severe
cases, frank liver failure may occur, necessitating a transplant.
Steatosis
Steatosis refers to the accumulation of fat within liver cells. It
is often associated with heavy alcohol consumption, but also occurs in
people who drink little or no alcohol (nonalcoholic steatosis). Studies
have shown that steatosis occurs in 30-70% of people with chronic
hepatitis C, although it is not yet known whether HCV infection itself
is directly responsible. The relationship between liver steatosis and
conditions such as obesity, high blood fat levels (hyperlipidemia),
insulin resistance, and diabetes is not well understood, but is
currently under study. Recent research indicates that people with
steatosis are at risk for more rapid development of fibrosis and
cirrhosis.
Several factors impact the rate of liver disease progression,
including alcohol consumption (which accelerates progression), sex (men
develop liver damage more rapidly than women, possibly due to a
protective effect of estrogen), age (younger people progress less
rapidly than older people, especially those over age 50), duration of
infection, and possibly HCV genotype shown in only a few small trials.
Assessing Liver Damage
Liver damage and dysfunction may be indicated by clinical symptoms
and by abnormal lab test results, including elevated levels of certain
liver enzymes (especially alanine aminotransferase, or ALT), reduced
levels of serum albumin, and prolonged prothrombin time (a measure of
blood clotting efficiency). However, some people with liver damage
experience few symptoms and have persistently normal lab results. New,
noninvasive methods for assessing liver disease progression are under
study, including tests that measure levels of collagen byproducts and
cytokines in the blood that may be markers for fibrotic activity.
The “gold standard” for assessing liver disease status is biopsy, in
which a small sample of liver tissue is withdrawn, stained, and examined
under a microscope for evidence of tissue damage. Liver biopsy results
are reported in terms of histological stages (alternative staging and
scoring systems, such as the Knodell Histological Activity Index, also
may be used). Unlike the established inflammation score—which reflects
current disease activity—these stages reflect degree of liver damage.
Stage I refers to liver inflammation without fibrosis. Stage II is
inflammation plus fibrosis confined to one portal of the liver. Stage
III indicates that fibrosis extends over adjacent portals (bridging
fibrosis), but nodules are not yet present. Stage IV is cirrhosis with
loss of normal liver architecture. People progress through these stages
at different rates; often people have early or moderate fibrosis for
many years without developing cirrhosis.
Treatment and Future Prospects
Research indicates that effective treatment with interferon and
ribavirin as well as lamivudine for HBV can slow or halt liver disease
progression, and may actually allow for some degree of repair and
reversal of existing damage, especially if it is not yet advanced.
Ongoing research may lead to the development of therapies that directly
inhibit the fibrotic process. Experts traditionally have discouraged
treatment of people with decompensated cirrhosis—because interferon, in
particular, can lead to a worsening of liver inflammation—but some
studies suggest that treatment of such people may in fact be beneficial.
New combination regimens and drugs in the development pipeline (such as
adefovir for chronic HBV) show promise. At this time, participation in a
clinical trial may be the best option for people with advanced liver
disease.
Fatty Liver Associated with Increased Mortality

Over
recent years I have written numerous times about fatty liver
(NASH) and the risks associated with it. Fatty liver can lead to
liver disease in individuals with or without hepatitis C and B.
Certainly having HCV or HBV may increase the risk for developing
fatty liver and liver disease. Other risk factors include
impaired glucose tolerance (insulin resistance, diabetes),
high-fat diet, elevated lipids, and metabolic syndrome. These
risk factors suggest HIV+ individuals may be at greater risk for
developing fatty liver. In addition, there is some controversy
about whether certain NRTIs may contribute to fatty liver.
Several studies have been conducted & found certain NRTIs did
contribute to fatty liver. You can find these articles and
studies on the NATAP website by using the SEARCH ENGINE on the
website, try searching for fatty liver, NASH. Here is the most
recent published journal articles on this subject.

Assessing the outcome of nonalcoholic steatohepatitis? It's time
to get serious
Hepatology October 2006

The hepatitis C virus (HCV) was discovered in the late 1980s,
and a decade later, drugs became available which could eradicate
the virus in almost half of infected patients. Quantitation of
the hepatitis B virus (HBV) through sensitive commercial assays
became possible only a few years ago; today, a wide range of
powerful antiviral drugs is available. In sharp contrast,
nonalcoholic steatohepatitis (NASH), which was first described a
quarter of a century ago,[1] became a subject of intense
scrutiny and publication in the following decades[2][3] and
although its disease spectrum keeps expanding,[2][4][5] the
overall perception in the majority of cases is still that of a
benign disease. The prognosis of nonalcoholic fatty liver
disease (NAFLD) has recently been rated from remarkably
benign,[6] unimpressive,[7] very unimpressive[8] to the use of
the I word (incidentaloma).[9] Of particular concern is that
most patients at risk for NAFLD are not primarily referred to
hepatologists but to specialists in the endocrine or nutrition
fields who seem to endorse an optimistic view of hepatic
steatosis and its consequences. Intriguingly (and sadly enough),
no single drug development program in NASH is currently
underway, while drugs designed for weight control or diabetes
treatment are, by and large, available and in fierce competition
among pharmaceutical companies.
When contemplating this paradox, one might first consider that,
even in liver diseases already established as leading causes of
liver failure (such as chronic hepatitis B or C, alcoholic liver
disease or hemochromatosis), the assessment of prognosis has all
been controversial.[10][11] Different views and seemingly
contradictory observations stem from the fact that most liver
diseases have considerable inter-individual variability in
presentation and natural course. HCV infection is a good
example: depending on the age of infection, sex, mode of
transmission and comorbid associations,[12] the disease could
take more than a lifetime before evolving to cirrhosis[13] or it
could undergo accelerated fibrogenesis[14] with a heavy impact
on short-term liver-related mortality.[15] HBV infection,
although a leading cause of mortality and liver cancer in
certain parts of the world, has been shown under certain
circumstances to evolve as a benign disease with no mortality or
disease decompensation in large cohorts of patients followed for
more than 30 years.[16] Overall, 20% or less of patients with an
alcohol intake considerably above the one associated with risk
of liver damage will ever go on to develop liver cirrhosis. To
add to this short list, it becomes increasingly unclear whether
in genetic hemochromatosis, iron overload alone could even
result in liver cirrhosis in the absence of other cofactors such
as alcohol, obesity, or HCV infection.
In NAFLD, this potential for individual heterogeneity is also
present, only exacerbated to a higher degree.
Fat accumulation in the liver seems to be a very early
event in the course of insulin resistance. As a result,
different profiles of patients with this disease are encountered
in clinical practice. These range from lean individuals with
minimal excess truncal fat to those with morbid obesity, or from
patients with normal glycemic control to those with full blown,
type 2 diabetes with metabolic complications. Unfortunately,
this also makes it almost impossible to perform adequate
clinical and prognostic studies over the entire spectrum of
liver injury, for several important reasons which are specific
to NAFLD. First, most patients with NAFLD, and probably almost
all of those with normal aminotransferases are not referred to
hepatologists (the opposite being true for patients diagnosed
with viral hepatitis infection) due to the perceived benignity
of steatosis and its silent presentation. Second, there is a
regrettable lack of a simple and specific diagnostic marker for
this disease, and therefore screening of large populations
through the current gold standard, liver biopsy, is impossible,
let alone that non-hepatologists are not at ease with the
procedure. Hence, observations from different populations will
always suffer from ascertainment bias and underreporting silent
NAFLD on a population-based level is inevitable and is expected
to keep feeding controversy. A study with perfect methodology
addressing the prognostic impact of NAFLD in the general
population would certainly be very welcome, but realistically
would be too complex to perform in the foreseeable future. In
the meantime, we should not overlook the accumulated knowledge
which points towards a more severe disease than was originally
thought.
What is the current knowledge of the clinical outcome of NAFLD?
Bland steatosis or steatosis with minimal inflammation
insufficient to qualify as NASH is most likely a nonprogressive
disease when occurring alone.[17][18] It is uncertain whether
the marginal proportion of cirrhosis occasionally
reported[19][20] reflects a real, albeit rare, propensity to
fibrogenesis or simply missed lesions of NASH at the initial
liver biopsy.[21] When steatosis occurs in association with
another liver disease, however, the situation might be different
as this seems to favor progression of fibrosis[22]; in this
case, the distinction between bland steatosis and
steatohepatitis is even harder to make with confidence. A wealth
of experimental data demonstrate a particular vulnerability of
fatty liver to numerous superimposed noxious agents.[23][24]
Caution is in order before concluding that bland steatosis is
benign.
Steatohepatitis on the other hand, can result in advanced
liver fibrosis and cirrhosis[25][26] in a significant
proportion of cases. From the hepatologist's perspective, NASH
is an important cause of advanced liver fibrosis in clinical
practice.[27] In a recent multicentric survey of 272 French
patients with chronic unexplained hypertransaminasemia,[28] 90%
of cases of cirrhosis were found in patients with
steatohepatitis. In fact, the importance of NASH as a cause
of cirrhosis is underestimated, as the diagnosis of NASH at
this stage relies more on exposure to cardiometabolic risk
factors (overweight, diabetes)[29] than on histological
features. Findings from the large UNOS database show a step-wise
increase between the proportion of cryptogenic cirrhosis and
increasing BMI, with cryptogenic cirrhosis being more frequent
in diabetics than in non-diabetics.[30]
The hepatologist's perspective on the importance of NASH can be
challenged due to considerable selection bias. However, an
important body of evidence from large unselected cohort studies
with long follow-up remind us that obesity and diabetes, two
strong prosteatogenic conditions, can induce end-stage liver
disease and its complications. After a mean follow-up of 13
years, obese, nondrinking individuals from the general
population had a 4-fold increased risk of dying from cirrhosis
or of developing its complications when compared to lean
patients.[31] Diabetic patients have at least a 2.5-fold higher
risk of dying from cirrhosis than the general population[32]
(again, a conservative figure considering that some
complications of cirrhosis such as infections can easily be
classified as unrelated). Long-term follow-up data from a
case-control study of diabetic males with a huge sample size
have shown a time-dependent increase in the risk of developing
NAFLD compared to non-diabetics: a 36% increase in those
followed less than 5 years and a 2-fold increase in those
followed more than 10 years.[33] Granted, most of these studies
did not exclude other liver diseases, such as viral hepatitis,
with state of the art molecular diagnostic methods. But it is
highly improbable that the bulk of liver disease in these
patients is explained by causes other than NASH, given the
strong epidemiological association between NAFLD and insulin
resistance. Moreover, numerous studies have now shown that in
countries with both low[34-38] and high[39][40] prevalence of
viral hepatitis, diabetes increases by 2- to 5-fold the risk of
another complication of cirrhosis, namely hepatocellular
carcinoma. Indeed, there is a consistent, dose-response
correlation between fasting and 2h serum insulin with the risk
of death from primary liver cancer in nondiabetic French men[41]
as well as a stepwise increase between fasting glucose levels
and the incidence and risk of death by liver cancer in Korean
men.[40]
A frequent liver disease that results in cirrhosis and liver
cancer should be sufficient as a cause of great concern.
However, arguably, only the demonstration of increased overall
and liver-related death could remove any reasonable doubt. Data
on this aspect are slowly emerging in the field of NAFLD.
NASH-induced cirrhosis reduces survival and predisposes to
decompensation of cirrhosis just as any other etiology.[42] An
important distinction, however, is that decompensation occurs
slowly in Child A cirrhosis, while in Child B or C, once
complications have occurred, the prognosis is particularly
grim.[42] This has been recently confirmed by Sanyal et al., who
further demonstrated that causes of death are liver-related and
predictors of survival are basically the same in NASH-induced
cirrhosis as in any other cirrhosis (MELD score and renal
function).[43] In the end, whether the outcome of NASH-induced
cirrhosis is better or worse than that of HCV-induced
cirrhosis[42-44] does not really matter and will be confounded
anyway by lead-time bias due to current limitations in the
diagnosis of NASH, as outlined above. Rather, we should be
concerned about how to diagnose NASH-induced advanced fibrosis
in high-risk patients and prevent its progression to cirrhosis,
as once decompensation occurs, little can be done to avoid a
fatal outcome in these patients who, for the most part, are
weaker candidates for liver transplantation.[42][43] A more
systematic attempt at reducing selection bias evaluated the
impact of NAFLD-related mortality at a population-based
level.[18] The results of this important study by Adams et al.
are, again, an eye-opener: patients with NAFLD are reported to
have an excess mortality risk of 34% over the general age and
sex-matched population after a mean follow-up of only 7.6 years
which, coherently, increased to 55% with a longer follow-up (10
years). True, this excess mortality is not entirely attributable
to liver failure. But cirrhosis was the third leading cause of
death in the NAFLD cohort versus the 13th in the control
population (which confirms previous findings[19]) with a median
survival shorter than 7 years.[18]
These data have nonetheless fallen short from settling any
controversy and fuel further debate. It has been argued that
since mortality occurs with cirrhosis, excluding these patients
from the survival analysis will show that NAFLD is in fact much
more benign than previously thought.[7] However, all chronic
liver diseases share one common feature, which is that mortality
occurs at the cirrhotic stage and not before. Excluding such
patients from the survival analysis will make chronic HBV and
HCV hepatitis look just as benign as NAFLD. And there is no
reason to exclude such patients when assessing the severity of a
disease that can induce cirrhosis: Adams et al. noted that
cirrhosis occurred during follow-up in 13 of their 21 cases.[18]
Failure to demonstrate impaired survival in noncirrhotic NAFLD
does not mean NAFLD is benign. It simply means that follow-up
was too short to capture the development of cirrhosis and the
occurrence of its complications; this comes as no surprise as
this typically takes 20 to 30 years in chronic hepatitis C.[13]
In line with these arguments, an important addition to the field
is made by Ekstedt et al. in this issue of HEPATOLOGY.[45]
The authors report on the long term clinical and histological
follow-up of a consecutive cohort of NAFLD patients initially
referred for investigation of abnormal liver function tests.
Information on clinical status was available in all 129 patients
and repeat liver biopsy in 68, after a mean follow-up of 13.7
years. Importantly, the authors were able to identify the
pathological form of NAFLD, NASH or simple steatosis, at
inclusion and hence study the natural course based on this
distinction. Patients with NASH had significantly reduced
survival compared to the age and sex-matched general population
and a significantly higher risk of liver-related (2.8% vs.
0.2%, respectively) and cardiovascular-related death (15.5% vs.
7.5%, respectively). End-stage liver disease (ESLD) occurred
in 10% during follow-up, including three cases of hepatocellular
carcinoma. Remarkably, and possibly because of the longer
follow-up, the authors were able to show that even patients
without cirrhosis developed ESLD (18%, 6/34 F2 and F3 patients)
during follow-up, thus refuting the claim that noncirrhotic NASH
is benign. In contrast, patients with steatosis but no NASH
had similar survival and similar causes of death as the general
population and displayed no ESLD. These findings confirm and
extend previous results[20][46] as well as acknowledge the
considerable potential for heterogeneity of the clinical course
in NAFLD and the need to incorporate the distinction between its
different pathological forms in future studies. Another strength
of the study by Ekstedt et al.[45] is the long follow-up period,
which extended well beyond the first decade after diagnosis.
This allowed the authors to document a significant proportion of
progression of fibrosis on repeat liver biopsy: 15 out of the
66 (23%) patients with F0 to F2 fibrosis on initial biopsy
progressed by 2 or more stages and 6 developed cirrhosis during
follow-up.
Last but not least, the study by Ekstedt et al., together with
previously published data[43] point to an intriguing finding
that might be critical for future research: the possibility of
increased cardiovascular mortality in patients with NASH.
Several studies have shown increased risk scores for
cardiovascular events (such as the Framingham score) in patients
with NASH,[47] even after adjustment for BMI, age and other
known risk factors.[48][49] Others have demonstrated a higher
prevalence of carotid plaques,[50][51] endothelial
dysfunction[47] or higher carotid media thickness in patients
with NAFLD.[51][52] A great challenge will be to specifically
evaluate the additional risk conferred by NASH, independent of
the underlying metabolic abnormalities.
Areas of uncertainty regarding the impact of NAFLD on a
population-based level exist, and legitimate questions are still
unanswered. However, it has become clear that for patients we
see in liver clinics, NASH is a disease with serious fibrogenic
potential which can result in liver-related morbidity and
mortality. As such, it should be regarded as a major unmet
medical need. Strategies for screening patients with
cardiometabolic risk factors for liver injury should be
implemented and large therapeutic trials should no longer be
delayed. As far as NASH goes the I word should neither be
incidentaloma nor inaction.

No Correlation Found Between Steatosis and Liver Fibrosis in HCV
Genotype 1 Infection
Liver steatosis
is generally regarded as a risk factor for chronic liver disease.
Moreover, steatosis is considered in HCV-related chronic active
hepatitis (CAH) as an adjunctive factor of progression and evolution
of liver disease. In particular, steatosis is thought to be
specifically related to the course of the disease in
genotype 3a patients with
CAH.
The aim of this
study was to test the role of steatosis in liver damage (fibrosis)
in a consecutive case-study of
genotype 1b patients who
have undergone
liver biopsy because of an
increase of serum ALT.
180 patients (
sex: M98/F82; median age: 51 range 17 - 68) underwent
ultrasound
examination and liver biopsy. Based on
liver histology patients
were divided according to steatosis into four classes: 1 (no
steatosis), 2 (steatosis < 30%), 3 (steatosis 30 – 50 %), 4 (steatosis
> 50 %).
Results:
·
Histological Activity Index (HAI) was evaluated according to ISHAK’
s score.
·
Median fibrosis value was S 2 (ranging 0 – 6; 23
patients showed liver cirrhosis) in all the 4 classes and no
statistical significance was found between groups.
·
Virological and epidemiologic characteristics,
biochemical data, BMI, Apparent Duration of Disease (ADD) of all
patients were recorded and statistical correlation checked.
·
A
univariate and multivariate analysis vs fibrosis were performed in
all the patients and tested statistically significant only for age,
ADD, diabetes and ALT (p< 0.00), but not for steatosis.
Conclusion
The authors
conclude, “Steatosis does not seem to be an independent adjunctive
risk factor of liver disease progression in CAH/genotype 1b HCV-infected
patients….Age,
ADD,
diabetes and
increase of ALT seem to be
the only independent factors associated with liver fibrosis
progression.”

Fatty Liver
Disease, ALT, & Overweight
Determinants of the association of overweight with elevated serum
alanine aminotransferase activity in the United States
Background & Aims: In the absence of other causes, overweight and
obesity increase the risk of liver disease. We examined whether central
adiposity and metabolic markers explain the association of body mass index
(BMI as kg/m2) with abnormal serum alanine aminotransferase (ALT) activity
in a national, population-based study.
Methods: Adult participants (5724) in the third U.S. National Health and
Nutrition Examination Survey (1988-1994) underwent anthropometric measures
and phlebotomy after an overnight fast. Participants with excessive alcohol
consumption, hepatitis B, hepatitis C, iron overload, or known diabetes were
excluded.
Results: Elevated ALT levels were found in 2.8% of the population. In
univariate analysis, factors associated with elevated ALT levels (P < 0.05)
included younger age, male sex, Mexican-American ethnicity, and higher BMI,
waist-to-hip circumference ratio (WHR), and fasting serum leptin,
triglyceride, insulin, and glucose concentrations. The proportion of
elevated ALT activity due to overweight and obesity (BMI 25 kg/m2) was 65%.
In multivariate logistic regression analysis, control for WHR, demographic
factors, and glucose concentration diminished but did not eliminate the
association of higher BMI with elevated ALT activity. After adding leptin
and insulin concentrations, abnormal ALT activity was most strongly
associated with higher WHR (odds ratio [OR], 1.32; 95% confidence interval
[CI], 1.12-1.56) and leptin (OR, 1.12; 95% CI, 1.01-1.24) and insulin (OR,
1.27; 95% CI, 1.01-1.60) concentrations, whereas BMI was not independently
related. Conclusions: In this large, national, population-based study,
central adiposity, hyperleptinemia, and hyperinsulinemia were the major
determinants of the association of overweight with elevated serum ALT
activity.

Defining nonalcoholic fatty liver disease:
Implications for epidemiologic studies
Jeanne M. Clark, Anna Mae Diehl
In the United States, chronic liver disease and cirrhosis are the 10th
leading cause of death overall, and among the top 7 leading causes of death
in men and women ages 45-64. Despite recent advances in technology,
physicians must still rely on the liver biopsy for diagnosing and
particularly for staging liver disease. Liver function tests including serum
transaminases and -glutamyltransferase are often used as screening tests
among both low- and high-risk populations. However, there is ample evidence
that these tests lack sensitivity and specificity for liver disease and
cirrhosis. Thus, despite increased interest in a broad array of liver
diseases, medical research has been hampered by a significant referral bias
because of the need for liver biopsy for accurate diagnosis and staging.
In this issue of GASTROENTEROLOGY, Ruhl and Everhart6 attempt to expand
our understanding of liver disease in the United States population, by
presenting an analysis of data from the Third National Health and Nutrition
Examination Survey (NHANES III). Using this data, they examine the
prevalence of an abnormal alanine aminotransferase (ALT), defined as an
ALT>43 U/L for men or women. By eliminating individuals with
moderate-to-high alcohol consumption, hepatitis B or C, elevated transferrin
saturation or a history of diabetes mellitus, the authors use the elevated
ALT as a surrogate for nonalcoholic fatty liver disease (NAFLD).
After these exclusions, they found that 2.8% of the population had an
elevated ALT. Elevated ALT was associated with younger age, male sex,
Mexican-American ethnicity, impaired glucose metabolism and insulin
resistance, obesity, and measures of central adiposity, as well as higher
leptin, triglycerides, and C-peptide. In multivariate analyses central
adiposity, insulin, and leptin concentrations were the most highly
associated factors. They conclude that these factors are the major
determinants of the association between elevated ALT concentration and
higher body weight.
As with any good research, this article leaves the reader with more
questions than answers. The first major question is how to study the
epidemiology and risk factors of a disease for which the gold standard
diagnostic test is an invasive procedure. Ruhl and other investigators
conducting epidemiologic research have used serum aminotransferases.
However, this has not been universally accepted, despite the lack of a
superior alternative. Accepting that aminotransferases are the best, widely
available serum markers of liver disease, it is unclear if ALT should be
used alone, as in this article, or whether aspartate aminotransferase (AST)
and ALT7,8 or other combinations of liver tests should be used. Furthermore,
the level of elevation that is considered abnormal varies widely and has
recently been brought into question.10 There is also debate as to whether or
not different cutoffs are indicated for men and women. In fact,
gender-specific norms for ALT were defined in the NHANES III manuals.11
Given all the controversy, it is clear that more acceptable and accurate
means of noninvasively diagnosing liver disease in general, and NAFLD in
particular, are needed.
The article by Ruhl and Everhart highlights the impact the current
uncertainty in noninvasive diagnosis can have on epidemiological studies.
Using ALT alone, they estimate the prevalence of NAFLD in the United States
is 2.8%. This estimate is much lower than general population estimates of
NAFLD in other countries, which range from 16%-20% based at least in part on
ultrasound evidence for hepatic steatosis. It is also substantially lower
than that predicted by a recent population-based study of seemingly healthy
Italian blood donors.10 Moreover, using recently suggested lower normal
values for ALT (>30 U/L for men and >19 U/L for women), Ruhl and Everhart
found elevated levels in 12.4% of men and 13.9% of women, estimates
significantly higher than their original 2.8%.
There are several reasons why Ruhl and Everhart may have arrived at a
lower estimate of NAFLD than other population studies. First is their
decision to use ALT alone as a marker for occult liver disease. Although
many have suggested that ALT is higher that AST in NAFLD, an elevated
ALT/AST ratio may be true only of early disease. Furthermore, in NAFLD, as
in most other types of chronic hepatitis, ALT values fluctuate over time.
Thus, diagnostic criteria that rely solely on a single elevated ALT value
could underestimate disease prevalence. In addition, the authors used a
higher cutoff value for normal ALT than many suggest (and one that is higher
than published in the National Center for Health Statistics NHANES III
manuals). Naturally, this would lower the estimated prevalence of occult
liver disease. Furthermore, as the authors themselves acknowledge, ALT
testing in NHANES III was conducted on serum that had been frozen.
Freeze-thawing of samples may affect enzyme activity and artifactually lower
ALT values, leading to an underestimation of disease burden in the
population. Finally, the authors excluded people with known diabetes, a
group who are at high risk for NAFLD. This eliminated a relatively large
subpopulation that is likely to be enriched with fatty liver disease, and
may have biased their conclusions. However, although several common causes
of liver disease were excluded from this study, it is likely that not all of
the remaining elevated ALT values were due to NAFLD. Some were probably
caused by other conditions, such as autoimmune hepatitis. This possibility
is supported by a recent biopsy study that demonstrated histologic proof of
NAFLD or NASH in only about 65%-90% of patients with "cryptogenic"
hepatitis. Nevertheless, Drs. Ruhl and Everhart's estimate of NAFLD
prevalence and the associations they found are likely to be more indicative
of the burden of NAFLD in the general population than information obtained
from patients who are selected for further study based on referral to
gastroenterology clinics. Even if the true prevalence of NAFLD in the United
States population is merely 2.8%, fatty liver disease would be twice a
common as chronic hepatitis C (1.3%).
This leads to the second question: what does a diagnosis of NAFLD really
mean? Stated another way, is this condition merely NAFL, or is it truly
NAFLD? Fatty liver is often considered to be an incidental condition with a
benign prognosis. However, a growing body of literature contests this idea,
indicating that the natural history of NAFLD, at least for some, includes
progression to cirrhosis and to hepatocellular carcinoma. The latter data
defy conventional wisdom, which suggests that most people with this
condition remain asymptomatic for decades. Indeed, the preponderance of
asymptomatic individuals with fatty liver has tempted some to conclude that
fatty liver alone may be a variant of normalcy, rather than a true disease.
However, applying similar logic would force one to conclude that
asymptomatic individuals with a blood pressure of 180/100 mm Hg, a fasting
blood sugar of 180 mg/dL, or low density lipoproteins of 200 mg/dL, while
abnormal, do not have a disease state. Fortunately, epidemiological studies
of hypertension, diabetes, and dyslipidemia have taught us that each of
these diseases is indolently progressive, leading to clinically
significantly morbidity and mortality in a subset of afflicted individuals
decades after disease onset. The knowledge of subsequent serious outcomes
drives the current practice of early therapeutic intervention in individuals
with those diseases.
Certainly, before NAFLD is dismissed as quirk of nature, more studies
are required to clarify its genuine, health-related outcomes. In addition to
elucidating the natural history of portal hypertension-related morbidity and
mortality, these should assess more subtle symptoms that may affect an
individual's quality of life. Our own analysis of NHANES III data, as well
as a recent prospective survey of NAFLD patients who were referred to the
Mayo Clinic, suggest that individuals with NAFLD may not be truly
asymptomatic because they describe their health status as significantly
below average. In addition, if NAFLD is part of the metabolic syndrome, as
these authors and others suggest, then it will be important to determine
what pathogenic role fatty liver plays, relative to the other components of
the syndrome. It will also be important to determine whether or not
treatment of NAFLD improves the other aspects of the metabolic syndrome, and
vice versa. Finally, more work is needed to identify which patients with
fatty livers are most likely to progress from steatosis to steatohepatitis
and cirrhosis. A better understanding of the factors that modulate liver
disease progression is critical, so that we can target selected patients for
more aggressive monitoring, lifestyle interventions, and pharmacotherapy.
In summary, it is important to emphasize that epidemiological studies
are crucial to further our understanding of many diseases, particularly
those that are indolently progressive over decades, like NAFLD. Ruhl and
Everhart6 have made a major advance toward clarifying the burden of liver
disease in the United States population. Their findings suggest that occult
liver disease may be much more common in the general adult population than
we previously suspected, affecting 4 to 5 million people. Moreover, evidence
that such ALT abnormalities associate with other components of the metabolic
syndrome supports the authors' conclusion that most of the abnormalities are
probably due to NAFLD. Given the increasing prevalence of obesity in
children, as well as adults, this has potentially important public health
implications. The cynics among us will argue that these interpretations are
premature without definitive histologic proof of fatty liver. Others remain
skeptical that, even if valid, the diagnosis of NAFLD rarely portends a real
risk for clinically significant adverse health outcomes. The debate is
likely to smolder until better, noninvasive tests to diagnose and stage
NAFLD are developed and used to identify and track afflicted individuals
over time. Until then, it seems prudent to place NAFLD in the same health
risk category as other components of the metabolic syndrome, and to consider
it no more or less worthy of medical attention than its "bed fellows," i.e.,
obesity, diabetes, hypertension, and dyslipidemia. Sometimes, "still waters
run deep."
Steatosis Identified as Risk Factor for
Liver Cancer in HCV-Infected Patients
NEW YORK (Reuters Health) Jul 02 - Hepatic steatosis
appears to be a risk factor for hepatocellular carcinoma (HCC) in
patients with chronic hepatitis C virus (HCV) infection, according to a
recent report by Japanese investigators.
Multiple factors, including cirrhosis, HCV genotype,
and total alcohol intake, have been tied to the risk of developing HCV-associated
HCC. Although hepatic steatosis is a common finding in patients with
chronic HCV infection, it remains unclear whether this liver abnormality
is also risk factor for HCC.
The new findings, which are published in the June 15th
issue of Cancer, are based on a study of 161 patients who were diagnosed
with chronic HCV infection between 1980 and 1999 at Nagasaki University
Hospital. All of the patients had no detectable HCC at enrollment. The
average follow-up period was 6.4 years.
The cumulative incidence rates of HCC at 5, 10, and 15
years after HCV diagnosis were 24%, 51%, and 63%, respectively, senior
author Dr. Katsumi Eguchi, from Nagasaki University School of Medicine,
and colleagues note.
In agreement with previous reports, older age,
cirrhosis, and not receiving interferon therapy were identified as
independent risk factors for HCC, the authors note.
In addition, Dr. Eguchi's team found that hepatic
steatosis was independently linked to an increased risk of HCC (p =
0.0135). Further analysis revealed that this liver abnormality
correlated with body mass index and with serum ALT and triglyceride
levels.
"Our data emphasize the need for the careful
monitoring of patients with chronic HCV and hepatic steatosis for the
development of HCC," the researchers state.
It is possible that the effects of steatosis on cancer
risk may persist even after achieving HCV clearance, Dr. Andrew X. Zhu
and Dr. Raymond T. Chung, from Massachusetts General Hospital in Boston,
note in a related editorial.
"However, before contemplate targeting steatosis as a
strategy to decrease the risk of HCC development in patients with
chronic HCV infection, it will be important to demonstrate that
steatosis is a critical step in the hepatocarcinogenesis pathway," they
add.

Fibromyalgia
By Lucinda Porter, RN
Lucinda K. Porter, RN is a research nurse and patient
educator at Stanford in the area of hepatology. She co-facilitates a support
group and is active in many aspects of hepatitis C education. In addition to
being HCV+, she has a life which include her husband and teenaged daughter.
The most
common complaints of patients with chronic hepatitis C are fatigue and
muscle or joint aches. These same symptoms also occur in patients with
fibromyalgia. Although most patients with hepatitis C who have muscle aches
do not have fibromyalgia, some patients may have both conditions.
Fibromyalgia is believed to affect two to six percent of
the U.S. population.The term fibromyalgia means "pain in the muscles and
fibrous connective tissue". Muscle pain and fatigue are two of the hallmark
characteristics of fibromyalgia syndrome, but these two symptoms can also be
associated with a host of other medical conditions.
For this reason, and because there is no specific test to
confirm this condition, fibromyalgia can be difficult to diagnose. In the
past, fibromyalgia was sometimes dismissed or overlooked by physicians. Some
patients were treated for psychological problems.
However, over the past 10 years, fibromyalgia has become
better understood and the symptoms that constitute an accurate diagnosis are
better defined.
Symptoms
Pain is the most common symptom. The location and description of the pain
can be key in helping a doctor make an accurate diagnosis. In 1990, the
American College of Rheumatology developed criteria for diagnosing
fibromyalgia syndrome. These include:
¥ At least 3 months of widespread pain in all 4 quadrants of the body.
¥ Bilateral pain in 11 of 18 specific trigger points. The trigger points are
located along the neck, shoulder, ribs, collarbone, hip and knee.
The pain associated with fibromyalgia has been described as burning,
gnawing, or aching. Pain is almost always present. Some say it feels like
having the flu. Sleep disturbances, fatigue, morning stiffness and headaches
sometimes accompany fibromyalgia syndrome.
Difficulty concentrating and mood changes may also be reported, although
this may be due to sleep disturbances commonly occurring with fibromyalgia.
Some patients complain of depression, but it is believed that depression is
more often a result of the symptoms caused by the fibromyalgia.
Causes
Although there is a great deal of research being conducted on the causes and
triggers of fibromyalgia, the cause is still unknown. Studies have shown
that people with fibromyalgia syndrome have decreased circulation to the
affected areas. They also have more substance P, a neuropeptide that acts as
a pain transmitter. There is speculation that inappropriate exercise or poor
posture may contribute to the condition. Trauma, infection, sleep
disturbances, stress, and hormonal imbalances have all been suggested as
possible causes.
Treatment
Trial and error is one of the ways that patients learn how to manage
fibromyalgia. Knowing what triggers exacerbations and what bring relief is
key.
Lack of sleep, strenuous exercise, and stress may act as triggers, while
relaxation techniques and moderate exercise may offer relief. Here are some
further treatment options:
¥ Physical therapy
¥ Stretching
¥ Moderate exercise (start very gradually)
¥ Massage (some people say certain types of massage worsens their condition)
¥ Hot baths
¥ Meditation
¥ Medication (Discuss this with your doctor. There are a number of options
to try, such as nonsteroidal anti-inflammatory or anti-depressant drugs.)
If you feel that you might have fibromyalgia, talk to your
physician. Although there may be similarities between the symptoms related
to hepatitis C and those of fibromyalgia, these two conditions are quite
different. Further, there are many other disorders that may cause similar
symptoms.
A well informed primary care doctor, a physiatrist or
rheumatologist can evaluate your situation and make recommendations. If your
physician lacks knowledge on the subject, or does not take your symptoms
seriously, find another doctor.

Fibromyalgia, Hepatitis C Infection and the Cytokine Connection
Fibromyalgia and chronic
hepatitis C infection share many clinical features including prominent
somatic complaints such as musculo-skeletal pain and fatigue. There is a
growing body of evidence supporting a link between cytokines and somatic
complaints.
This review by researchers
in the Division of Arthritis and Rheumatic Diseases, Oregon Health & Science
University, discusses alterations of cytokines in fibromyalgia, including
increased serum levels of interleukin (IL)-2, IL-2 receptor, IL-8, IL-1
receptor antagonist; increased IL-1 and IL-6 produced by stimulated
peripheral blood mononuclear cell in patients with FM for longer than 2
years. Other cytokine alterations discussed include
-
increased gp130, which
is a neutrophil cytokine transducing protein;
-
increased soluble IL-6
receptor and soluble IL-1 receptor antagonist only in patients with
fibromyalgia who are depressed; and
-
IL-1 beta, IL-6, and TNF-a
by reverse transcriptase-polymerase chain reaction in skin biopsies of
some patients with fibromyalgia.
In addition, this review
describes the mechanism by which alterations in cytokines in fibromyalgia
and chronic hepatitis C infection can produce hyperalgesia and other
neurally mediated symptoms through the presence of cytokine receptors on
glial cells and opiate receptors on lymphocytes and the influence of
cytokines on the hypothalamus-pituitary-adrenal axis such as IL-1, IL-6, and
TNF-a activating and IL-2 and IFN-a down-regulating the HPA axis,
respectively.
The association between
chronic hepatitis C infection and fibromyalgia is discussed, including a
description of key cytokine changes in chronic hepatitis C infection. Future
studies are encouraged to further characterize these immunologic alterations
with potential pathophysiologic and therapeutic implications.

Gallbladder
TITLE: The prevalence of gallstones in chronic liver
disease is related to degree of liver dysfunction.
BACKGROUND/AIMS: Earlier studies have indicated an
elevated risk for gallstone disease in patients with cirrhosis. This study
aimed to evaluate the prevalence of gallstones in patients with chronic
liver disease (CLD) with respect to sex, etiology, and severity of liver
disease.
METHODOLOGY: Four hundred and thirteen adults (176 women),
mean age 51.2+/-14 years, with CLD, who had undergone liver biopsy during
1978-1993, and from whom sera were available, were investigated
retrospectively. The results were compared with a population-based
ultrasonography study of 556 healthy men and women, in their 40s and 60s.
RESULTS: The prevalence of gallstones in patients with CLD
did not differ from that in the control population. An increased frequency
was observed in patients with CLD initially classified as cryptogenic, of
whom the majority (60%) later were reclassified as chronic hepatitis C. The
frequency of gallstones was also high in PiZ-heterozygotes for
alpha1-antitrypsin deficiency (5/21, 24%) compared to non-PiZ-carriers
(17/389, 4.8%), (p less than 0.001). In 67 patients with histologic evidence
of cirrhosis, 30% (20/67) had gallstones (vs. 15% in the general population,
p less than 0.01). The prevalence of gallstones increased significantly from
Child's class A (16%) to C (56.2%). The difference was significant in males
(18.2% vs. 62.5%, p=0.033), but not in females. Fifty percent of the
patients with gallstones were symptomatic.
CONCLUSIONS: Progressive liver dysfunction is a risk
factor for gallstones particularly in males. HCV infection and PiZ
carriership may further increase biliary lithogenesis.

Know Your Body: The Gallbladder
What Could Be Worse Than A
Bad Hair Day?
Suddenly, you feel a
sharp, gripping pain in your rib cage from breastbone clear through to
shoulder blade. It eases some then worsens again. You feel nauseas and
begin to sweat. "Oh, God! I'm having a heart attack!", you say to
yourself. When you get to the hospital, the doctor may believe you're
having one, too. However, after exhausting all other tests, he'll often
check for a gallstone that's blocked somewhere in your bile duct and know
the truth.
Then you'll be in bed with a tube in your nose suctioning your stomach and
receiving intravenous injections of vitamins and medication for pain for
it is constant. This will continue until the internal swelling goes down
(maybe a couple of days). Usually, your doctor will tell you your only
viable option is removal of your gallbladder, called a cholestcystectomy.
If your case is not considered too severe, they may do a less radical
surgery and break up the stones but removal is considered the safe bet.
Hopefully, with surgery, you will only risk a large and very unattractive
scar, very little improvement in your ability to eat foods you enjoy and
about 10 days off work with a tube sticking out draining the bile until
your body accustoms itself to the drastic changes it has undergone. Some
people have endured much worse such as a disruption of their liver or
other ducts, wound infection, bleeding, bile leakage, and liver disease
(jaundice).
Have I just presented you with a very unlikely scenario? Am I using scare
tactics? Ask any one of the over 500,000 people experiencing this
nightmare ( cholecystectomy) each year. They'll tell you that there is no
surgery on earth too dangerous, no risk too great to ease this pain.
Autopsies reveal that 80 percent of all people who reach 90 have
gallstones. Estimates rank around 20 million people in the U.S. Of course,
you don't have to have a gall bladder attack to have gallstones. Most of
the symptoms of gall bladder problems are silent or are attributed to
other causes.
Symptoms
Some of the symptoms
include periodic pains much like the ones described above but easing
pretty quickly, chronic indigestion, intestinal gas & cramping and often,
an overall sluggish feeling. Duodenal Ulcers occur when the gall bladder
is unable to get the bile into the duodenum to neutralize the stomach
acid. Hepatitis could also be stone-related since it's basically an
inability for the liver to dump all the poisons it has cleaned from the
blood.
Also, Claude M. Lewis, D.C. reveals a symptom I've never attached to gall
bladder function: High & Low Blood Sugar. When a stone blocks the path to
the duodenum, the bile will reverse course under the pressure of the
muscular contraction and enter the pancreas' "back door". When this
happens, the pancreas will feel irritated and produce insulin since it
doesn't realize this irritation is not a cry for insulin.
According to Dr. Lewis, after doing a gall bladder cleanse, many diabetics
have had to closely monitor their insulin intake since their need for it
drops as much as seventy-five percent! How's that for results?
Sometimes, you have gallstones but none of these symptoms. In a case like
this, you may never know it or it may hit you so suddenly. Anytime.
Anywhere.
Where Is The Gall Bladder
& What Does It Do?
It is pretty well surrounded by the liver in the upper right side of the
abdomen under the rib cage and has small fluid line called a bile duct
connecting it to the liver, pancreas and duodenum. The GB muscle which
attaches to the rib cage produces powerful contraction when irritated.
Basically, it's just a sack that holds fluid composed of water, bile salts
& cholesterol. When it comes out of the liver it is primarily water. The
Gall Bladder just stores it until 95% of the water is drained away and
then ejects it into the duodenum through the bile duct.
What Causes Gall Stones?
Interestingly, there
still isn't much known in the medical community about why a gall bladder
allows the cholesterol to separate from the bile salts. However, it is
known that high cholesterol intake is not necessarily to blame since even
people fasting have been found to have high cholesterol and stones in
their gall bladders.
I learned several very interesting facts in my studies for this article.
For instance, did you know that gallstones can form in the liver even
before it is sent to the gall bladder? Basically, gall stones are made
up of cholesterol and some bile salts. Every once in a while they may have
some calcium in them but not often.
The pain is a result of the gall bladder's large, powerful muscle which is
attached to the rib cage, which is contracting in an effort to release
bile into the duodenum to neutralize the acid from the stomach. Thus, a
stone anywhere in the bile duct, from the liver's exit to the gall
bladder's or the pancreas (which shares a common bile duct). Is capable of
producing deathlike pain.
In the book ARE YOU "STONED"?, Dr. Lewis describes the actions surrounding
the common bile duct as response to irritations. For example, the stomach
is the only part of the body made to run in an acid condition. Th |
