• A triple antioxidant protocol combining alpha-lipoic
acid, selenium, silymarin can improve outcomes in patients
with hepatitis C, in some cases averting the need for
conventional interferon/ribavirin treatment or liver
transplant, said Burt Berkson, MD, at the annual meeting
of the American Holistic Medical Association.
' I’ve never seen someone with frank hepatitis
cured on conventional therapy”, said Dr. Berkson,
who practices in Las Cruces, New Mexico. “Viral
loads may drop, but they quickly bounce back when treatment
is stopped.
Standard therapy with pegylated interferon and ribavirin
give clinically meaningful reductions in viral load
in less than 50% of all patients. And that’s foe
the more susceptible HCV types 2 and 3. The numbers
are under 20% for HCV type 1. These drugs also carry
a significant side effects burden of severe flu-like
symptoms, anemia, depression, thrombocytopenia, autoimmune
reaction, renal problems, hair loss, and neuropsychiatric
symptoms.“This is definitely a situation in which
the treatment is often worse than the disease. We need
something else. We need to try non-toxic protocols first”,
said Dr. Berkson.
For the past decade, Dr. Berkson has utilized an antioxidant
protocol consisting of alpha-lipoic acid (ALA), 300mg,
twice a day; oral selenium, 200 mcg, twice a day; and
oral silymarin (Milk Thistle), 300 mg per day. “I
put all people infected with HCV on this combination,
even if they are asymptomatic. I think you can prevent
progression to frank liver damage.”
The antioxidant combination increases platelet count,
increases albumin production, reduces ALT and slows
prothrombin times to near normal. In some cases, abdominal
ascites are resorbed. In addition to the ALA, silymarin
and selenium, Dr. Berkson also recommends a good B vitamin
complex because high dose ALA will deplete thiamine,
niacin and riboflavin.
This combination of nutrients forms the nucleus of a
comprehensive nutrition and lifestyle approach that
emphasizes a vegetable and grain-rich diet, stress reduction,
avoidable of highly processed foods, iron-rich foods
(iron promotes hepatic damage), and elimination of tobacco,
alcohol and other substances of abuse. He often advises
patients to take coenzyme Q10, omega-3 fatty acids,
psyllium fiber, and beta-carotene, while avoiding over-the-counter
medicines like Tylenol that can be very damaging to
the liver.
A study by US Army researchers looking at hepatitis
C in Korean War era veterans showed that lifestyle factors
were a major predictor of poor outcomes. Poor diet,
high stress and frequent alcohol use were strong predictors
of disease progression and death (Seeff LB et al. Ann
Int Med 2000; 132(2): 105-11).
Dr. Berkson initially published his triple-antioxidant
protocol in 1999, in the content of a pilot study involving
three patients with cirrhosis, portal hypertension,
and esophageal varies related to HCV. All three were
candidates for liver transplant. After a year on ALA,
selenium and silymarin, all were healthy, showed improved
hepatic function, were able to return to work, and most
importantly, avoided transplant (Branson BM. Med Kiln
(Munch) 1999; 94 suppl.; 83-9).
Assessment and Evaluation
There are many different lab tests that can be used
to assess the hepatic and overall health status of a
patient with HCV. Unfortunately the numbers often lead
to more confusion than clarity. Dr. Berkson relies on
four key measures: platelet count, albumin levels, alanine
aminotransferase (ALT), and viral load.
Platelet Counts: Progression of hepatitis-related
liver damage leads to hepatic congestion and portal
vein hypertension. This, in turn, leads to splenomegaly.
As this occurs, platelets sequester, leading to measurable
thrombocytopenia.
Albumin Levels: As virally induced
apoptosis continues in the liver, albumin production
tends to drop, making this a good marker for overall
liver damage.
Alanine Aminotransferase (ALT): Elevated
ALT may or may not be predicted of severity or poor
outcome in hepatitis C. However, an abnormally low level
of this enzyme is a clear indicator of end-stage cirrhosis.
“They just don’t have enough liver cells
left to produce the ALT enzyme,” said Dr. Berkson.
Consequently, it is an important value to keep an eye
on.
Viral Load: While it is important to
track viral load, it is essential to remember two things:
First, there is no clear correlation between serum HCV
levels and the degree of liver damage. Second, viral
testing methodologies, especially those based on polymerase
chain reaction (PCR) technology, give highly variable
and often exaggerated results. Particle estimates based
on PCR are, “an artificial amplification of the
actual amount of virus present in the blood, often by
many millions,” said Dr. Berkson. Any single measurement
of viral count is essentially meaningless; only by tracking
viral load over time, using a consistent method, can
one assess viral activity.
Lab tests should be part of a comprehensive assessment
that includes careful history, and diet and lifestyle
assessment.
Careful physical evaluation is also important. In particular,
clinicians should be on the lookout for ascites. The
portal hypertension secondary to cirrhosis often causes
a ballooning of the small vessels of the digestive tract.

Alpha
Lipoic Acid
Dr. Berkson’s interest in ALA extends back to
the 1970’s. In 1979, he published an article describing
use of ALA, then called thioctic acid, as a rescue therapy
for acute hepatotoxicity caused by ingestion of Phalloides
mushrooms (Berkson BM. N Engl J Med 1979; 300(7); 371).
ALA is one of nature’s strongest antioxidants,
particularly in neutralizing superoxide, free radicals.
“I figured that if it could be used in acute liver
disease, it might be useful for chronic liver disease
as well.
ALA, a veritable sponge for free radicals, is produced
naturally by the body in large quantities when we are
young, but tends to drop off with age. In inflammatory
disease, especially with a lot of macrophage activity,
there are a lot of superoxide free radicals to sop up
(Sigalou AB. Antioxid Redox Signal 2002 Jun; 4(3): 553-7.).
“ In Russia, they use ALA for people with myocardial
infarctions, to limit ischemic damage.”
ALA is also a key co-factor in the enzymatic process
by which pyruvate is converted to acetyl co-A (Roche
TE, Cate Rl. Biochem Res Commun 1976; 72(4): 1375-83.).
“Without it, we get no energy from our cells.”
Organ meats are a rich dietary source of ALA, though
it would be difficult to get therapeutic levels from
diet alone. The majority of ALA supplements are derived
from either tissue culture or they contain synthetic
ALA.
For most HCV patients, oral supplementation with 300
mg ALA, twice daily, is sufficient to control free radical
damage in the liver, said Dr. Berkson. He stressed the
importance of selecting products carefully. “Use
a good one. Make sure it is from European source materials,”
to rule out contamination or sub-therapeutic dose levels.
He recommended ALA products by Metabolic Maintenance
(www.metabolicmaintenance.com) and Bio Tech Pharmacal
(www.bio-tech-pharm.com), though he has no financial
ties with either company and acknowledged there are
other high-quality products on the market as well.
Some patients with advanced disease, especially those
with severe cirrhosis, require intravenous ALA. Dr.
Berkson, gives this as 100 mg IV, twice daily for five
days. The main difficulty with IV ALA is that the product,
Thioctacid 600T, is not available in the US. It is made
by a German company called AstaMedica. “Aventis
was going to come out with it in 2006, but it looks
like that’s not going to happen. You have to write
prescriptions for each patients, and have them order
from pharmacies in the US can make it, but you need
to ask about the source. It must be IV prescription
grade.”
Selenium
This trace element is, “almost like a birth control
pill for retroviral replication,” said Dr. Berkson.
When selenium is low, viral replication increases. As
you raise the selenium level, you reach a point at which
viral replication just stops. The mechanism behind this
effect is not entirely clear.
In treating patients with HCV, he recommends 200 mcg
oral selenium as selenium methionine, twice daily. There
is also an intravenous form, called Selinase, which
is available in Germany, But he seldom uses it. “We’ve
had such wonderful results with the oral selenium that
there’s really no need to go IV.”
It is very important to keep the daily dose around 400
mcg. Higher levels will add nothing to improve antiviral
efficacy, and a daily intake of 800 mcg can be toxic.
“You don’t want to go too high or people
will start feeling sick, develop skin problems and in
some cases lose their hair.”
Silymarin
Silmarin is an aggregation of flavonolignans derived
from the Milk Thistle plant (silybum marianum), and
it is the most commonly used botanical medicine for
liver disease.
According to a summary from the Agency for Healthcare
Research and Quality (AHRQ), Silymarin has anti-oxodant
and antifibrotic effects in the liver. It also appears
to block the entry of toxins also liver cells, and down-regulates
inflammation (Agency for Healthcare Research and Quality
2000. US DHHS, Publication 01-E024).
There are three well-designed clinical trials of silymarin
in hepatitis patients in the medical literature; all
shows measurable benefit, through in one of the three,
the finding were not statistically significant. (For
a review of silymarin and other natural therapies for
Hepatitis, join www.holisticprimarycare.net and download
our article, “Nutritional Therapies, Botanicals
Can Improve Outcomes in Chronic Hepatitis” in
our July 2003 edition).
As part of his triple antioxidant protocol, Dr. Berkson
recommends a total of 1,800 mg of a standardized silymarin
product, to be taken in divided doses. Typically, this
involves taking three 300-mg capsules with breakfast
or lunch, and another three capsules at dinner.
The triple antioxidant regimen is a long-term treatment
strategy, through many patients reported rapid improvements.
According to Dr. Berkson, “People say they feel
better after one week, and after one month they fell
great. Even those who continue to drink alcohol seem
to do pretty well on this protocol.”
