Hepatitis A Treatment
If you think you’ve been exposed to
hepatitis A, contact a doctor or your local health department.
You could help prevent the spread of hepatitis to other people.
Hepatitis A infection usually clears up
on its own. It may take a few weeks. There is no specific
treatment for hepatitis A. Some doctors may prescribe medications
or actions that will help reduce the symptoms of the infection.
Get lots of rest, drink water, and avoid alcohol or other
chemicals that could harm the liver.
If you have chronic hepatitis B or C and
are exposed to hepatitis A, call your doctor. The illness
could be more serious in people with liver disease.
The best way to treat hepatitis A is to
prevent it; consult a healthcare provider about vaccination
against hepatitis A!

Hepatitis B Treatment
Today, there are a number of treatment options
for Hepatitis B. These treatments were developed and improved
in the past 10-15 years, so if in the past your doctor told
you that there are no treatments for hepatitis B, ask again!
If you were infected recently (within the
last 6 months) you may want to see if you get rid of the
virus on your own before starting treatment.
Before treatment is started, it is important
to make sure there is indeed a current hepatitis B infection.
It sounds silly, but tests for Hepatitis B are often misinterpreted-
even by doctors. Some blood tests will be positive if a person
was vaccinated against Hepatitis B or was infected with Hepatitis
B and recovered. Make sure the test for hepatitis B surface
antigen (HBSg) is positive before you consider taking hepatitis
B treatment.
Not all cases of hepatitis B need to be
treated and treatment usually doesn’t need to be started
right away. Your doctor may want to do a liver biopsy before
deciding about treatment. The biopsy will allow the doctor
to see if liver scarring or fibrosis is present.
There are pluses and minuses for each treatment
so take some time to learn about the treatments and discuss
the details with a doctor experienced in treating Hepatitis
B.
The treatments help reduce the amount
of virus in the body - which reduces damage to the liver.
The less damage to the liver, the better the liver can
function. Preventing more damage and improving the health
of the liver is the goal of the current hepatitis B treatments.
There are a few treatment options: interferon
and anti-viral medications.
Interferon is
a protein that the body produces in very small amounts
to help fight off infections. Interferon is also manufactured
and available as a medication to treat health conditions
including Hepatitis B and Hepatitis C. Interferon for Hepatitis
B is currently prescribed in two forms : Interferon-alpha
and pegylated interferon. Interferon-alpha is currently
sold under the names of Intron A, Infergen, and Roferon.
Interferon-alpha is injected under the skin daily or a
few times a week. Pegylated interferon is currently sold
with the names Pegasys and PegIntron. It is injected once
a week. Pegasys was recently approved by the FDA for hepatitis
B treatment.
There are side effects to interferon treatment,
but there appears to be no risk of viral mutations. Side
effects usually include flu-like symptoms (fatigue, headache,
bodyaches), depression, and headaches. Many of these side
effects can be managed by drinking more water, getting more
exercise, sleep, and eating a balanced diet. Medications
can also help relieve the side effects. If you have side
effects, you should talk with your doctor about ways to eliminate
or manage them.
Lamivudine (sometimes
called 3TC) is a pill or oral solution that is taken everyday
for about 1 year, though sometimes longer. It is currently
sold under the names of Epivir-HBV, Heptodin, and Zeffix.
Lamivudine directly attacks the virus makes it hard for
it to replicate. This medication has been used at higher
doses for years to treat HIV.
There are few side effects from this
medication, but the virus can mutate and become resistant
to the medication and possibly harder to control. Sometimes
hepatitis gets worse when treatment is stopped. It is important
to be very compliant with the treatment. Treatment with
a combination of interferon and lamivudine is being studied.
Adefovir dipivoxil (HEPSERA) is a pill that
is taken once a day for a year or more. Like lamivudine,
it interferes with the viruses ability to replicate. Adefovir
appears to produce fewer mutant viruses than lamivudine,
though long-term studies are still under way. Like lamivudine,
hepatitis can get worse when treatment is stopped. Some people
who developed mutants on lamivudine are prescribed Adefovir.
It is very important to be compliant and
take the medication as prescribed. This will help you reduce
the amount of virus in the body and reduce the likelihood
of mutant formation.
Entecavir is another antiviral medication
that is available as a pill or oral solution. It was very
recently approved by the FDA and is currently sold under
the name Baraclude. The medication is taken every day for
a year or more. Like the other antiviral medications, it
is possible for hepatitis to get worse after treatment is
stopped.
Talk with your doctor about length
of treatment and medication doses. While there are standard
recommendations, each patient’s circumstance is different.

Hepatitis C Treatment
Hepatitis C treatment has improved substantially
during the past few years. The treatments today are easier
to manage and more effective than just a few years ago. If
your doctor told you in the past that there are no treatments
for hepatitis C, ask again!
Before treatment is started it is important
to make sure there is indeed a current hepatitis C infection.
Some people do recover from hepatitis C infection on their
own, so make sure that both the antibody screening test is
positive and virus is detected before treatment is started.
Who should receive treatment
If you were recently infected with hepatitis
C, your doctor may want to wait to see if you fight off the
virus on your own before starting treatment.
Not all people need to be treated for hepatitis
C and some health conditions like heart disease or psychiatric
conditions may be affected by the treatment. Doctors will
consider a number of things before prescribing treatment
such as:
- Fibrosis or nodule formation in their
liver biopsy. Patients with these conditions usually progress
to cirrhosis. Elevated liver enzymes (ALT and AST)
- Other health conditions
- Detectable hepatitis C virus (remember
that any amount of detectable virus means a person is infected)
- Ability to follow the treatment plan
Some people and doctors consider waiting
until the hepatitis “gets worse” before starting
treatment. It is important to note that the more fibrosis
in the liver, the less effective the treatment. So, waiting
until there is significant fibrosis in the liver reduces
the chances of a positive response to the therapy.
Talk with your doctor about your situation.
Consider getting a second opinion.
Interferon and ribavirin:
Interferon has been used for years to treat
hepatitis. The treatments have improved over the years. Initially,
interferon-alpha was taken by itself and injected 3 times
per week. Interferon taken alone is called interferon monotherapy.
Interferon monotherapy was improved by the addition of ribavirin.
Ribavirin improved the effectiveness of the interferon therapy.
The next improvement to therapy was the
introduction of pegylated interferon. Pegylation is the addition
of a molecule to the interferon to extend it’s survival
in the body. Pegylated interferon is injected once a week
and the level of interferon in the blood fluctuates less.
Use of pegylated interferon alone is monotherapy. Pegylated
interferon is also used in combination with ribavirin. The
effectiveness of pegylated interferon is improved with the
addition of ribavirin.
Trade names for interferon include Intron
A, Infergen, and Roferon. Two pegylated interferons are approved
for hepatitis C treatment. PegIntron is pegylated Intron
A. Pegasys is pegylated Roferon.
Trade names for ribavirin include Rebetol
and Copegus. Generic ribavirin is also available.
Length of treatment
The recommended length and dose of treatment
varies by genotype of the virus, treatment history, weight,
and in some cases amount of damage to the liver.
In general, recommended length of treatment
for genotype 2 and 3 is 24 weeks. The general recommended
length of treatment for genotype 1 and 4 is 48 weeks. If
a patient was treated with interferon and ribavirin in the
past and relapsed, doctors will sometimes retreat the patient
and continue for a longer period of time. It is important
to stay on treatment for the recommended time period and
not stop if the virus is undetectable! Compliance with recommended
therapy is the best chance for success.
Dose of medication varies by the product
used and sometimes the weight of the patient and treatment
history. Some may want to reduce the dose of their medication
if side effects appear. It is important to discuss and try
side effects prevention or management rather than reduce
the treatment dose. Getting a second opinion about side effects
management or joining a support group can often help.
How well does the treatment work
Response to therapy is measured by
reduction in the level of hepatitis C virus in the blood.
Patients respond differently therapy. It is hard to predict
how any one individual will respond to the therapy at the
start, but your doctor will follow your response by checking
your viral load periodically through treatment.
Most patients will experience a reduction
in viral load. A couple of factors influence how well the
treatment works. These factors include the virus genotype
(patients with genotypes 2 and 3 generally respond better
than those with genotypes 1 and 4), how well a patients complies
with the treatment, and the extent of fibrosis or scarring
in the liver.
Treatment response is typically measured
at 12 weeks, 24 weeks, at the end of therapy, and at 6 months
after treatment.
- Early Viral Response (EVR):
This is the response measured at 12 and/or 24 weeks. Most
people who will go on to clear the virus will see a significant
drop in the level of virus in the blood at this point.
Doctors and insurance companies typically expect to see
at least a 2-log drop in viral load (this means for example,
from 2 million iu/ml to 20,000iu/ml). Sometimes the virus
has dropped enough to be undetectable. It is possible for
people who do not see this drop to go on and clear the
virus, but it is not common. Some insurance companies
are cutting off payment for treatment if the 2 log drop
is not achieved. Do all you can to take all
the medication all the time to increase your chance of
an EVR! Talk with your doctor about ways to reduce
side effects without reducing the dose of medication. Make
sure you have all your pharmacy and lab issues addressed
before starting treatment. You don’t want to miss
doses because you don’t have the medication on hand!
If you do not see an EVR, talk with your doctor about the
continuation of treatment.
- End of Treatment Response
(ETR): This is the response measure at
the end of treatment. Ideally, the virus will be undetectable
at this point. If it is not, your doctor may recommend
continuing treatment for an additional period of time.
You should discuss pros and cons with your doctor.
Remember that even if you still have some detectable
virus, the treatment will have helped your liver fight
off the virus and that your liver is likely is healthier
than before.
- Sustained Viral Response
(SVR): This is the response measured
6 months after completion of treatment. If the virus
is undetectable at this point, it is called sustained
viral response. Most, about 95%, of people who achieve
SVR stay that way. Some doctors say the SVR patient
is “cured”. Other people do not use that
term, for they fear the virus may still be there but
at very low levels that can’t be measured. At
this point we know that those who achieve SVR, do not
appear to have any additional damage to the liver!
- Relapse: The
virus becomes undetectable during treatment but comes back
once treatment stops. Some believe that the virus may remain
in some liver cells during treatment and when treatment
is stopped, the virus starts to replicate again. Patients
who relapse should discuss other treatment protocols (including
increasing dosage or length of treatment) with their doctor.
- Nonresponse: Virus
is detectable during and after treatment. Patient who do
not respond to the therapy should talk with their doctor
about altering treatment protocols. Some patients who do
not respond have had difficulty taking all their medication
due to side effects or life events. These patients may
respond if all the medication on time for the entire time.
Others just do not respond to treatment even if they are
very compliant. These patients should discuss options with
their doctor. Some doctors will suggest waiting for new
treatments, others may suggest changing the treatment protocol,
others still may recommend that the patient continue to
take interferon at a low dose for a long period of time.
This “maintenance therapy is believed to help prevent
liver damage.
What is the expected level of response? Medical
treatments have improved greatly in the past few years,
and the percentage of patients who are Sustained Viral
Responders has also increased. The data below is compiled
from a number of sources. It is not possible to predict
how any one patient will respond until treatment has started.
There are factors that influence success of treatment (see
influences section below).
- When interferon-alpha is used alone,
about 15% of patients will achieve SVR.
- When pegylated interferon is used alone
about 30% of patients will achieve SVR.
- Combination therapy (interferon-alpha
and ribavirin) raises the SVR percentage to about 40%.
- Combination therapy (pegylated interferon
and ribavirin) increases the SVR percentage to over 50%.
- More than 95% of patients who achieve
SVR have no evidence of the virus 5 years after treatment.
What influences treatment success ? Some
things improve the chance of responding to therapy:
Genotype of virus.
Genotypes 2 and 3 may require only 6 months of treatment
and the likelihood of achieving SVR are about 80%!!
Baseline Viral Load. Starting
treatment with a viral load of 800,000 iu/ml or higher
is less favorable.
Race. For
reasons that are not understood, African Americans
do not respond to treatment as well.
Obesity. Obese
patients do not respond as well to treatment as those
who are not obese.
Cirrhosis. Patients
who have cirrhosis or advanced fibrosis do not respond
as well to treatment.
It is impossible to change most of
these factors. You can’t change your viral genotype
or race, for instance. But ,if you are very overweight,
you might lose weight before starting treatment to improve
your chances of responding.
The liver can benefit from treatment
even if the virus is not eliminated. Sometimes doctors
stop treatment if they don’t see the virus go away.
Consider discussing the benefits of continued treatment
with your doctor.
Treatment side effects
Many patients experience side effects
from the two medications used to treat hepatitis C. The
side effects can range from slight discomfort, to inconvenience,
or disability. Most of the side effects can be prevented
or managed, so don’t let fear of side effects interfere
with treatment decisions.
Interferon side effects
Some side effects from interferon show
up soon after treatment is started (early side effects)
other appear later in the course of treatment or stay with
the patient during treatment (persisting side effects).
Early Side Effects
- Flu-like (Inflammatory) symptoms
- Fever
- Chills
- Body Aches
- Headache
- Nausea
- Treatment – Anti-Inflammatory Medications
- Ibuprofen
- Naproxyn sodium (12-hour anti-inflammatory)
TIP:When you begin taking
interferon take the anti-inflammatory medications for the
flu-like symptoms BEFORE flu-like symptoms
appear. It will be more helpful in reducing symptoms. Think
of a snowball rolling down a hill – it’s much
easier to stop at the top of the hill than halfway down.
- Fluids – Dehydration can make flu-like
symptoms worse. Adequate hydration can help reduce side
effects.
- Drink enough water to keep your urine
a very pale yellow
- Stop drinking a couple of hours before
bedtime to reduce the need for nighttime bathroom visits
- Caffeine is a diuretic (pulls fluids
from the body), so avoid or limit caffeine while on interferon
therapy
TIP: Morning headaches
can be relieved by drinking a large glass of juice or water.
Persisting Side Effects
The side effects that appear later in interferon
use can be difficult to deal with. They usually begin a couple
of weeks or several months into treatment. The side effects
are usually not severe enough to stop therapy and these side
effects can be relieved with use of other medications. Talk
with a doctor about the side effects and try not to reduce
or stop therapy.
- Neutropenia (suppression
of neutrophils, a type of white blood cell)
- Neutrophils fight infection
- Dealing with neutropenia – a
medication called Neupogen can help
reduce neutropenia.
- Treatment is considered when neutrophil
count falls below 750,000 per ml (some may wait until
count goes below 500,000)
- Neupogen is usually taken once per
week
- Most effective when used a day or
two before interferon injection
- Some physicians may choose to reduce
the dose of interferon to stop suppression of neutrophils.
However, this can reduce the effectiveness of interferon
therapy, so patients should discuss the use of Neupogen
with their doctors.
- Psychiatric Side Effects
- Depression – interferon
therapy can cause true depression as well as these depression-related
symptoms like
- Insomnia
- Short-tempered/irritability
- Fatigue
- Crying episodes
- Loss of appetite
- Treatment of depression--
Antidepressants
Doctors and nurses may suggest taking an antidepressant
if symptoms appear. Some even suggest that you take antidepressants
BEFORE interferon therapy is started since it takes a
few weeks for antidepressants to become effective. Sometimes
depression gets worse as treatment continues. Increasing
the dose of antidepressants can help. Consulting a psychologist
can also help.
- If serious depression occurs, intervention
of a psychiatrist is helpful. The doctors can work together
so that hepatitis therapy can continue.
- Although rare, more serious psychiatric
conditions occur, such as severe, suicidal depression.
In this case immediate psychiatric intervention is needed,
and interferon should be stopped.
A few other side effects may occur. While
unpleasant, they usually are not dangerous and gradually
return to normal after therapy stops. They include:
- thinning hair,
- change in hair texture
- weight loss
Ribavirin side effects
- May cause birth defects
- Women who may become pregnant must
use reliable birth control.
- Pregnant women may not take ribavirin.
- Women should not become pregnant for
six months following the end of ribavirin therapy.
- If a woman is pregnant and her male
partner uses ribavirin she should make sure he uses a
condom with every act of intercourse – ribavirin
is found in seminal fluid.
- Anemia
- Can be treated with medication called erythropoietin.
Names for erythropoietin are Epogen and Procrit.
- Most patients see some improvement
after two doses, but it takes several weeks before the
full effect is felt.
- Some physicians may reduce the amount
of ribavirin; this can reduce the effectiveness of treatment
so consider use of erythropoietin.
- Nausea
- Take ribavirin with food to reduce
this side effect
- Rashes
- Physicians may suggest skin creams
or antihistamine
- A dermatologist can be consulted
- Allergy – ribavirin
treatment must be stopped.
Please discuss all side effect
concerns with a doctor.
Nonresponders and Relapsers
For those who have taken treatment for
hepatitis C and have not achieved an SVR, there are new approaches
to therapy. There are no “breakthrough” treatments
available, but many doctors are trying techniques to improve
response. This could be retreating again for a longer period
of time for people who relapse. For some people who are nonresponders,
a different type of interferon called consensus interferon
is sometimes used with ribavirin. This interferon is not
available pegylated, so patients who take this interferon
(also called Infergen) must have an interferon injection
every single day. Studies are underway to see how well this
treatment works, focusing on the patients who are the most
difficult to treat. These are usually people with genotype
1, have a high viral load, and many times are African American.
Many of these patients have cirrhosis or advanced fibrosis.
If you are a nonresponder to pegylated interferon and ribavirin,
talk to your doctor about whether you might benefit from
Infergen. If you or your doctor want references for this
treatment please contact HepTREC at info@heptrec.org.
Maintenance Therapy
Nonresponders with cirrhosis might benefit
from maintenance treatment. This consists of pegylated interferon
at a lower dose than usual (half or one-third) without ribavirin.
Doctors think that interferon can help “cool down” inflammation
in the liver and might prevent liver failure and liver cancer.
This approach is currently being studied in three large nationwide
trials. Talk to your doctor if you are a nonresponder, or
have cirrhosis. In some cases people with advanced cirrhosis
who are not able to take full-dose pegylated interferon and
ribavirin might be able to take lower dose peginterferon.
If your doctor is not familiar with this treatment, check
into the studies. If you or your doctor want references for
this treatment please contact HepTREC at info@heptrec.org.
Future Treatments for Hepatitis C
Many organizations are working to develop
better treatments for hepatitis C. Most work toward supplementing
or modifying existing treatments; some are testing drugs
that were developed for other conditions to be used against
HCV.
You can monitor clinical trial activity
for HCV at www.centerwatch.com and
the HCV Advocate web page
