Evaluate Alternative Therapies for Hepatitis C
A new study evaluating the effectiveness of complementary
and
alternative therapies for
hepatitis C has concluded that they may
be "promising" treatments.1
No Definite Conclusions
Complementary therapies have been widely promoted as treatments for
hepatitis C. But their efficacy is controversial, and are not regulated by
the Food and Drug Administration.
A 2002 survey found that, among nearly 1000 patients
being treated for various liver diseases at six U.S. clinics, as many as
39 percent had used some form of alternative therapy, mostly herbals and
botanicals.2
Consequently, doctors at Peninsula Medical School at the
Universities of Exeter and Plymouth in Exeter, England wanted to find out
which complementary therapies, if any, might have potential against
hepatitis C.
Confirming Study Findings
Joanna Thompson-Coon, Ph.D., and Edzard Ernst, M.D., Ph.D., both of
the School of Complementary Medicine at Peninsula, researched the medical
literature for previous studies testing the efficacy of a range of
alternative therapies for HCV.
"Systematic searches were conducted in six databases,
reference lists of all papers were checked for further relevant
publications, and information was requested from experts," the two
researchers reported.
Coon and Ernst found 27 previously published clinical
trials that were relevant, all involving herbal products and supplements.
In about half of the trials, patients had received interferon-alfa
treatment along with a complementary therapy. But only 11 of these trials
were of sufficient quality, making their results plausible. The other
trials, Coon and Ernst determined, had questionable outcomes because their
designs were also questionable.
Effective CAM
In each of the previous trials, patients had been divided into two groups;
one, taking the active therapy, and the second group (control group)
taking a non-active treatment as a comparison. "Compared with the control
group, significant improvements in virological and/or biochemical response
were seen in trials of vitamin E, thymic extract, zinc, traditional
Chinese medicine, Glycyrrhiza glabra, and oxymatrine," the researchers
concluded.
Vitamin E
Vitamin E has been shown to reduce the ill-effects of oxidative
stress in the livers of people with hepatitis C.3 In fact, this
vitamin is known as an antioxidant, nutrients that act to protect your
cells against the effects of free radicals, molecules that are damaging
by-products of the body's metabolism. Free radicals can cause cell damage
that can contribute to disease.4
Thymic Extract
Thymic extract is made from the thymus of cows. The thymus has an
important role in immune function by enticing white blood cells to become
T cells that recognize particular foreign invaders in the body, and become
part of the body's defenses against infection.5
While one study at the University of Alabama found
thymic extract monotherapy was not effective against hepatitis C,6
other studies using thymosin (a hormone of the thymus) combined with
interferon-alfa as combination treatment
for HCV was effective at reducing viral load.7 And one pilot
study showed this combination treatment was more effective than
interferon-alfa monotherapy.8
Zinc
Zinc, an antioxidant like vitamin E, has been shown to enhance patients'
responses to interferon therapy.9,10
Chinese Medicine
Traditional Chinese medicine has involved the use of schisandra, a plant
whose effects have been studied mostly in animals. The studies have
suggested that fruit from the plant can protect the liver, benefits liver
enzymes, and provides an antioxidant effect.11,12 But other
herbs used in this category have also been implicated as a possible
treatment.
Glycyrrhiza glabra is also known as a licorice plant.
Its dried root contains a potentially therapeutic substance known as
glycyrrhizin, and has been used for centuries as part of traditional
Chinese medicine.13
While some previous research has only involved lab
studies, it has suggested that glycyrrhizin may have antiviral properties.14
But a review of previous clinical trials found glycyrrhizin has the
potential to reduce long-term complications in chronic hepatitis C in
patients who have not responded previously to interferon.15
And a study in 1997 suggested glycyrrhizin may help
prevent liver cancer in chronic HCV patients.16
Oxymatrine
Oxymatrine is a substance found in sophora roots. In a comparison of
oxymatrine versus vitamins in one study, nearly half of 43 patients had
reduced their viral load to non-detectable levels, compared to only one
patient taking vitamins, researchers at the University of Shanghai in
China reported.17
However, while liver enzyme levels were higher in the
treatment group after two months of treatment, they were generally the
same between both groups after 3 months, the researchers reported.
In the end, Coon and Frist "identified several promising
complementary therapies", but definitive conclusions couldn't be drawn
because of questionable designs of the studies they had researched.
"More research is warranted to establish the role of
these and other therapies in the treatment of hepatitis C," they wrote.

| Complementary and
Alternative Medicine for Hepatitis Patients - By: Christopher
Maloney, N.D. |

If your current
treatment plan isn’t working, find one that will |

| Story: |

There are many
treatments available to those who suffer from hepatitis, but some are
more effective while some have more side effects than others.
The standard
therapies include interferon (which boosts the immune system) and
ribavirin (an antiviral drug). Adding ribavirin to interferon
increases the chances of suppressing the hepatitis. The new, longer
lasting pegylated interferons have a greater effect, while thymosin
and glucocorticoids (steroids) have no benefit.
The standard
therapies come with a promise of benefit for up to 60 percent of
patients, but they also have significant side effects. Depression,
autoimmune reactions, blood changes and infectious disorders may
prevent up to 25 percent of patients from continuing therapy.
More importantly,
patients may not be good candidates for interferon therapy. In a
German study of hepatitis C patients, 73 percent of patients did not
meet the criteria for treatment. The reality of multiple medical
diagnoses makes it necessary to find alternatives for these patients.
For many patients
there are no standard medical options, and patients are left to wait
for the next medical breakthrough or to look for alternatives on their
own. Most doctors are able to provide little guidance beyond the
standard treatments.
3
simple rules
Once beyond the
confines of the hospital, a patient is likely to be bombarded by
supplements and plans that claim everything under the sun. Consumers,
therefore, should follow three basic rules when considering
alternative treatments. The first rule is that if an individual is
receiving money from selling something, he or she is unlikely to be a
good source of objective information. The second rule is that if
something is supposed to cure everything, it doesn’t. The third rule
is that natural does not mean harmless, and if side effects occur, a
person should discontinue use immediately.
Too often
alternative medicine is surrounded by magical thinking, where normal
body processes are ignored. Simply because something was prayed over
or came from a shamanic recipe, patients will continue to take it long
after it has proven to be ineffective and/or is causing significant
side effects.
A physician needs to
be informed of any experimentation. Patients who are embarrassed to
tell their doctors about experimentation need to realize that their
reluctance may be life threatening. The safest choices are either to
stop experimenting or to find a doctor with whom they feel comfortable
speaking freely.
Doctors familiar
with and open to alternative therapies are far more available now than
they were even 10 years ago. The American Association of Naturopathic
Physicians and the American Holistic Medical Association are two
sources of licensed doctors.
Got
milk thistle?
Any alternative
treatment for hepatitis should include milk thistle (Silymarin
marianum). Long-term studies of alcohol cirrhosis found that taking
420mg of milk thistle daily decreased death rates by 7 percent. Milk
thistle halves the death rate from acute mushroom poisoning and
prevents lead poisoning destruction of the liver. Animal studies show
that milk thistle prevents destruction and preserves liver function.
Milk thistle has no antiviral effect and has a side effect picture
equivalent to placebo. It is nontoxic and can prevent death at a cost
far lower than standard drug regimens.
While milk thistle
blocks fibrotic damage, bile salts (UDCA) cut the elevation of liver
enzymes in half. In combination therapy with interferon, UDCA halved
the relapse rate of those responding. The bile salts provide raw
materials to the liver, lowering inflammatory buildup. The addition of
licorice to bile salts also significantly lowered GGT inflammatory
levels, but licorice can have significant side effects.
In 22 randomized
trials, the plants from the phyllanthus plant family were found to be
equivalent to interferon in removal of hepatitis B markers in the
blood, although no large trials of the plants have been done.
A huge number of
other plants have been shown effective against the hepatitis viruses.
In Sudanese medicinal plants, 34 of 71 plants had antiviral effects
against hepatitis C. Of these, eight had a greater than 90 percent
inhibition. No human or animal trials have been done, despite the fact
that in the , standard treatment is unavailable.
A variety of Chinese
formulations also are effective in lowering hepatitis C markers, and
both rosemary and tomatoes have been shown to be protective of the
liver. Gingko biloba has antioxidant properties and was liver
protective in a short-term trial. It is also a vasodilator that may
affect bleeding, so it should be used under supervision.
Diet’s important
Within the diet,
specific changes should be instituted immediately. Several studies
have shown that low-iron-intake diets have been effective in lowering
inflammatory markers for patients with hepatitis. Patients in had
significant inflammatory drops without anemia. In , inflammation was
halved when iron intake was halved. None of these patients had been
diagnosed with hemochromatosis (massive liver iron overload).
Looking at the liver
function provides a context for the results of medical studies. The
destruction of the liver from hepatitis results from chronic,
long-term inflammation. Standard medical treatment increases the
immune response with interferon while providing support (with
ribavirin). If successful, the virus is destroyed. If unsuccessful,
standard treatment tries the same thing, expecting different results.
Liver function is not optimized beyond restricting alcohol.
Complementary
medicine increases day-to-day liver functioning. Milk thistle provides
antioxidant support while blocking toxin uptake by liver cells. Bile
salts speed the processing of the liver and decrease its need to
create bile salts. Rosemary and a host of other herbs provide
antiviral support. But adding supplements without removing other
impacts on the liver is like putting fingers in a dike.
Maximizing liver
function involves the idea of a liver load. At a given time, the liver
can process only so much material. Within standard medicine we see the
overload of the liver as drug side effects and the occasional drug or
alcohol overdose. But like an overworked office worker, the liver
experiences various levels of load long before it quits. Daily living
places a tremendous strain on the liver, which processes everything we
eat. It must take care of last weekend’s buffet in addition to the
constant sleep deprivation and stress hormones. Add a chronic virus
and the necessity for rest and repair in a frantic world, and you have
a recipe for fibrosis. A constant routine, eating a very healthy diet
and minimizing unnecessary drug and supplement intake (including
vitamin megadoses) will go a long way in preserving liver function.
One of the effects
of decreased liver function is called hepatic encephalopathy. The
backup of unprocessed body toxins, including ammonia, affects brain
function. Increasing bowel clearance (which removes processed toxins
excreted by the liver and gall bladder from the body) has been shown
to be effective in decreasing symptoms. Another therapy is decreased
protein intake, done under a doctor’s supervision. The use of
probiotics (good intestinal bacteria) may also be helpful in
minimizing liver load.
Prior to
experiencing brain symptoms, it would be wise to treat the body like
it has a chronic viral infection. Patients are familiar with viral
infections in the shape of colds or flus, and may forget that the
viral response of the body to a liver virus is similar. Rather than
waiting for interferon to boost the immune system, simple treatments
(hot packs over the liver, avoidance of sweets, plenty of fluids,
etc.) will certainly not harm and will help prevent other illness.
While there are no studies on garlic and hepatitis, garlic is twice as
effective as drug antivirals against the flu and also acts as a
broad-spectrum antibiotic. Patients taking garlic capsules had half
as many flus and the flu symptoms lasted half as long. In treating
viral load, one should look at the body as a whole, rather than
fixating on the liver load alone.
Money matters
Chronic disease is a
great drain on financial resources. Individuals too ill to work may be
unable to support themselves, adding that tremendous stress to the
viral illness. After exhausting standard treatments, an individual
might partner with a doctor to treat themselves for a chronic viral
illness. A possible treatment plan requiring no extra money would
include eating brown grains, very good quality oils, nuts and seeds,
and a rainbow of fruits and vegetables. A patient could learn to do
lymphatic drainage massage and stretching exercises, including tai chi
or yoga. Liver processing could be maximized by regular small meals,
more bitter tasting food (which stimulates bile excretion) and by
gentle massage of the liver and abdomen or hot and cold packs over the
area. Strong smelling household spices, including rosemary, would be
used freely.
An individual
without a lot of money would be wise to research any supplement prior
to purchase. Products with independent laboratory testing are
available to all naturopathic physicians. Any product purchased should
be put through an individual objective trial for symptom resolution
and lowering of liver inflammatory levels. Three months would be the
maximum trial, with improvement often seen within days. Milk thistle
and bile salts would be high on my list of possible choices, which
also would include the phyllanthus plant family from reputable Eastern
importers. The bottom line: If your current treatment plan is not
working for you, find one that will. |
