ABSTRACT
Hepatitis
C (HC) is a major cause of liver disease with 150,000 to 170,000
reported cases annually in the United States.
Up to 80% of HC virus (HCV) infected individuals become
chronic carriers with risk of developing cirrhosis and
hepatocellular carcinoma. Interferon-a
(IFN a) the current and only FDA approved HC
treatment, exhibits a low long-term remission rate (~
20%). IFN-a,
however, is prohibited in acute hepatitis and is not effective in
treating cirrhosis, as well as demonstrates many side effects,
some potentially serious. Chinese herbal medicine provides better
HC treatment with higher remission rate, fewer side effects, and
lower cost when compare to IFN-a.
Traditional Chinese medicine classifies HC into three types: 1) damp
accumulation in liver
and gall bladder. 2)
weaker kidney, and 3) stagnation of liver.
Accordingly, the treatment consists of
1) removing damp,
2) tonifying the kidney,
3) moving Liver qi and
transforming Phlegm, as well
as 4) reducing toxin
accumulation and cooling Blood.
The effects of Chinese herbal medicine has been documented
clinically and experimentally and appeared to be mediated by
inhibiting HCV replication, correcting disordered microcirculation
of liver, restoring aberrant immunologic function, facilitating
hepatocyte regeneration, and providing deficient trace elements. The
effects of Chinese herbal medicine in treating HC can be easily
monitored through sequential measuring blood liver function
enzymes. Formula for
treating individual
patient would be carefully prepared based on individual condition. In summary, HC can be effectively treated by using Chinese
herbal medicine with minimal to no side effects and with a low
cost.
INTRODUCTION
HC
is caused by HCV. Both
cytocidal replications of HCV and immunologically mediated events
have been implicated for its pathogenesis.
The incubation period for HCV hepatitis ranges from 12 to
180 days. Most cases
are considered to be asymptotic.
Symptoms are non-specific and consist mainly of fatigue,
headache, anxiety and drowsiness.
A clinical feature quite characteristic of HCV is episodic
elevations in serum transaminases, with intervening normal or near
normal period. At
least 80% of individuals infected with HCV become chronic carriers
and about 10-20 % of the patients will develop cirrhosis and is at
risk for hepatocellular carcinoma.
CDC estimated that HCV causes about 85,000 new cases of
chronic hepatitis each year in the USA. Indeed, HCV is the leading cause of chronic liver disease in the Western world.
The
histologic hallmark of progressive diseases is piecemeal necrosis.
With continued loss of hepatocytes, subsequent fibrous
septum formation, and accompanied hepatocyte regeneration,
cirrhosis occurs. Liver
biopsy could provide useful staging information in HCV hepatitis.
Approved
drug for the treatment of HCV hepatitis by FDA is alpha interferon
(INF-a). Approximately 40% of patients will respond
to interferon for a six-month treatment, showing the normality of
the liver transaminase
tests and reduced hepatocytes inflammation.
However, among them who responded to the treatment,
approximately 60% will relapse several months following the
therapy. Only about
20% to 30% of the cases treated with INF-a enjoy a long-term remission.
Moreover, patients with cirrhosis are less likely to
respond to INF-a
therapy, and INF-a can not be applied for acute infections.
INF-a could cause many side effects and some of
them are serious. They
include fatigue, muscle pain, flu-like symptoms, autoimmune
disorders, severe depression and psychotic states, poor appetite,
hair loss, insomnia, and bone marrow depression.
It is noteworthy that a relatively high proportion of
patients treated with INF-a showed an increase of serum ALT during or
after therapy, suggesting that INF-a
induce liver damage.
APPROACH OF TRADITIONAL CHINESE MEDICINE FOR TREATMENT OF HC
HC
incidence is high in China, accounting for one third of world HC
cases. Treatment modalities of HC have been extensively studied in
China. It is well
documented that Chinese herbal treatment is more effective than
INF-a
expressed by higher remission rate, long term effect, minimal side
effects, and low cost. Physicians
in China employ an integrated approach for HC.
Diagnosis of HC is made via serology study, enzyme
biochemistry, and liver biopsy.
Herbal medicine in certain formula is applied to patients.
The experiments and clinical observations showed that
extracts of herbs used in treating HC have pharmacological effects
of anti-viral, anti-inflammatory, anti-fibrosis, and correcting
aberrant immunologic function.
Chinese herbal medicine could heal damaged liver cell,
clear jaundice and cease and reverse cirrhosis.
Virus
elimination depends on the host immune system.
It has been documented that extracts of herbs used in
treating HC, Acanthopanax bark, Epimedium, Siberian solomonseal rhizome, Honeysuckle
flower, and Dandelion
can reinforce functions of mononuclear-macrophage system, Astragalus
root, White atractylodes,
and Scrophularia root
can reinforce humoral immunity, Ginseng,
Codonopsis root, Lucid
ganoderma, and lycium fruit can reinforce cellular immunity.
These herbs can facilitate repairing injured hepatocytes
caused by dysfunctioned immune system.
Immune regulatory effects of herbs Licorice
root, oldenlandria, Scutellaria root, Tripterygium wolfed hook
and Millettia stem can
suppress aberrant auto-immunity in chronic active hepatitis.
Another
group of herbs has potent effects in reducing inflammation of liver
and normalizing elevated ALT and AST, by stabilizing damaged cell
membrane of hepatocytes.
Herbs of Schizandre
Fructus, Silybum marianum and Artichoke
are effective in normalizing elevated ALT and AST in 75% of
cases studied and reducing elevated ALT and AST down to 84% to 97
% of patients’ ALT and ASTs. The average time for
reducing or normalizing the enzymes
is about 8 to 12 weeks. By
applying a formula consisting of extracts of Schixandrae
Fructus, Silybum marianum and
Artichoke as principle ingredient together with Salvia root, Lucid ganoderma,
and Liquorice root, I
have experienced a high successful rate in normalizing liver function enzymes within three months.
To clear jaundice, especially during acute stage of HC,
herbal formulae containing Capillaris
Herb could be used. Gardenia
Fruit and Rhubarb
Rhizome are effective in less than three weeks.
Liver
cells have strong ability to regenerate.
The regeneration is closely related to intake of trace
elements, such as zinc and strontium.
HC patients show significantly deficiency of trace elements
in the blood and hair. Enrichment
of trace elements in herbs of Astragalus
root, White attractylodes, Codonopsis
root, Bupleurum root, and Lycium
fruit explains their effectiveness in treating HC.
Herbs
of Chinese angelica root,
Salvia root, Peach seed, and
Curcuma root are effective in decomposing collagen, and
promoting liver cell regeneration. These
herbs then can be used to normalize liver function and prevent
cirrhosis.
It
has been documented that HC patients have obvious microcirculation
disorders, which include increased abnormal vascular loops and
diminished or completely obstructed blood flow in capillaries in
the liver and in other tissues. This is consistence with the
theory of blood stagnancy
in traditional Chinese medicine on HC expressed by purplish
tongue, dark ring around eyes, enlarged capillaries, body ache,
and choppy pulse. By applying herbs of Salvia
root, Millettia stem, Achyranthes root, Ligusticum rhizome,
and Pseudoginseng,
an effect of invigorating circulation and expelling blood
stasis occurs.
CLASSIFICATION
OF HC AND ITS TREATMENT BY CHINESE HERBAL MEDICINE
The
following presents a traditional Chinese medicine approach for
classification and treatment of HC based on differentiation
of HC (characteristics of individual patient). The treatment would
be tailored to individuals based on clinical presentation.
Furthermore, treatments are also modified at different
stages of the patient's disease.
Chronic HC can be classified into three types based on my
experience.
1. Dampness
pathogen accumulation in liver
and gall bladder
The
toxic pathogen of HCV causes obstruction of qi
and leads to illness. HCV
pathogen is not a wen-re/warm-hot
toxic pathogen. Although
it directly enters yin
and blood, there are no clinical manifestations of heat in yin and blood,
which is commonly expressed as rashes, scarlet tongue, delirium,
tendencies to damage the blood or cause bleeding. HC
pathogen is a yin-natured,
toxic, damp-type
pathogen. This
pathogen has an obstructing nature of damp,
and a congealing nature of yin.
It can be accumulated to become toxic, blocking collaterals, damaging qi
and obstructing flow of yang
qi. This is
indicated by knotted mass under ribs, telangiectasis, and darkened
face.
2. Weak Kidney
Weaker
Kidney and Jing qi, weaker
qi and blood, and less efficient channel
and collateral
circulation occur following aging.
Accordingly, when yin
du (contagious pathogen) enters yin
xue (nutritive qi and blood), it then
obstructs yin and blood
in the zang fu (viscera), and resides stubbornly deep within body.
Thus treatment must be effective in tonifying Kidney,
restoring energy and nourishing blood.
Kidney
deficient patients, especially those in middle or old age, are
easily infected by HCV. Studies
in China showed a positive correlation between age and HC, with
patients in the 60-70 age group were most affected.
Studies in Japan showed similar results.
It has been found that predominantly damp-heat
cases were mainly associated with pathological manifestations of
mild hepatitis, whereas those with predominantly stagnation-related
conditions almost all were chronic hepatitis or liver
cirrhosis, and every case in the series was over 40 years of age.
Treatment
modality: Tonifying
Kidneys
The
most common subtype of this group is Kidney
qi deficiency and Kidney yang deficiency,
followed by Kidney yin
deficiency. A
judicious amount of Kidney yang tonics should
be applied by taking Ba Ji Tian (Morindae Officianalis, Radix), Hu
Lu Ba (Trigonellae Foeni-graeci, Semen), Xian Ling Pi (Epimedii,
Herba), Xian Mao (Curculiginus Orchioidis, Rhizoma), Tu Si Zi (Cuscutae,
Semen), and Wu Wei Zi (Schisandrae Chinensis, Fructus).
Some Kidney yin tonics should be added in order to seek yang from within yin.
In general, less Kidney tonics should be used in acute mild case, and more kidney
tonic should be used in chronic case.
Large dose of raw Huang Qi
(Astragali, Radix, 30g) can be very effective to treat HC, because
hepatitis C congeals yin, damages qi and blocks
yang.
3. Stagnation
of Liver Qi
Liver
and Spleen disharmony is
common in HC, expressed by Liver
oppressing a weak Spleen
or Liver qi blockage of Spleen.
Nature of HC pathogen - congealing accumulation, low-grade heat
symptoms, qi blockage, damp
obstruction and phlegm
formation, usually appears with stagnant
blood blocking the collaterals. Toxicity, stagnation,
phlegm and damp occur and
they interact with each other.
Treatment modality is to move liver
qi, transform phlegm by using qi movers
listed below: Chai Hu (Bupleuri, Radix), Chen Pi (Citri
Reticulatae, Pericarpium), Qing Pi (Citri Reticulatae Viride,
Pericarpium), Xiang Fu (Cyperi Rotundi, Rhizoma), and Hou Po (Magnoliae
Officianalis, Cortex). Above
herbs should be combined with following phlegm
cutters: Ban Xia (Pinelliae Ternata, Rhizoma), Zhe Bei Mu (Fritillariae
Thunbergii, Bulbus), and Kun Bu (Algae, Thallus).
Formula should be carefully formulated in order to reduce
any possibility to exacerbate congealing and obstructing. Commonly
used formula to reduce phlegm
accumulation are Er Chen Tang (Two-Cured Decoction or Citrus and
Pinellia), and Xiao Xian Xiong Jia Zhi Shi Tang (Minor Sinking
Into the Chest Decoction plus Zhi Shi).
OTHER MODALITIES USED IN TREATING HC WITH CHINESE HERBAL
MEDICINE
-
Moving and cooling blood
and reducing toxin
accumulation.
When
pathogen enters and works in blood,
herbs being capable of reaching blood
should be used. However
because pathogen tends to congeal yin
and become toxic, these so called blood
herbs should not be too cold, sticky, or passive. Instead, herbs with a property of moving without staying (zou
er bu shou, to move the blood
and open the collaterals)
should be used. When
HC pathogen is not responding to treatment, it is usually because
the illness has entered collaterals, rather than channels.
Collateral-opening
herbs are then needed to reach this area to clear the pathogen.
Ji Xue Teng (Spatholobus), by both nourishing and moving blood,
and opening collaterals,
is effective for this condition.
Anti-toxin herbs,
which can reduce toxic accumulation, move blood
and open collaterals,
are listed below: Bai Hua She She Cao (Oldenlandiae Diffusae,
Herba), Chi Shao (Paeonia Rubra, Radix), Da Huang (Rhei, Rhizoma),
Hu Zhang (Polygonum cuspidatum, Radix), Dan Shen (Salviae
Miltiorrhizae, Radix), Mu Dan Pi (Moutan Radicis, Cortex), Zi Cao
(Lithospermi seu Arnebiae, Radix), and Yu Jin (Curcumae, Tuber).
In
febrile disease, one method used in treatment is to vent heat from yin out to qi,
as the heat can be more easily dispersed, followed from the qi
out to the surface. The
idea is to lead the heat out from its deep position in the body to a more superficial
location and preventing the illness from worsening. Whether this technique should be used for a given hepatitis C
patient depends upon circumstances.
When patients have mild symptoms and with no history of IV
drug use or blood
transfusion, small amounts of herbs, which assist yang
and reduce toxicity in order to bring the pathogen out to the
surface, can be used.
CHANGE OF YOUR LIFESTYPES
Eat
a low-protein, low-fat diet.
Digesting protein puts an inordinate workload on the liver, so I recommend strongly limiting your intake of concentrated
protein foods, such as meat, fish, and diary products.
One ounce serving of tofu will give you all the protein you
need for the day. Eat plenty of starches, vegetables and fruits.
Take
some standard antioxidant formula. You can help your immune system fight the hepatitis C virus by taking
the supplemental formula I recommend to all my patients: 1,000 to
2,000 mg vitamin C and 25,000 IU mixed carotenoids at breakfast;
400 to 800 IU vitamin E and 200 mg selenium at lunch; and 1,000 to
2,000 mg vitamin C at dinner.
Strictly
avoid all alcohol and tobacco. Alcohol is toxic to the liver
and can accelerate liver
disease, while smoking takes a major toll on the immune system.
Try
to avoid all drugs,
whether prescribed, over-the-counter, or illegal. Most drugs are
metabolized by the liver.
Even common painkillers such as acetaminophen, when combined with
alcohol, have been shown to cause severe liver
damage.
Drink
plenty of water. Flushing
your kidneys with lots
of good-quality water will allow your body’s purification system
to do its job and take some of the workload of detoxification off
of the liver.
Take
frequent steam baths or saunas. Sweating
helps the body eliminate toxins
and also reduces the liver’s
workload. Be sure to replace lost fluids by drinking plenty of
pure water at the same time.
Get
plenty of rest. Give
your immune system an edge by cutting down on unnecessary
expenditures of energy, while maintaining a gentle exercise
regime.
Manage
stress. Effectively
coping with stress is considered to be a crucial component in
managing viral and autoimmune chronic hepatitis. Connect with
nature through practicing TAI CHI CHUAN,
APPENDIX:
BLOOD TESTS IN HAPATITIS C
Detection
o f hepatitis:
ALT (SGPT) / AST (SGOT)
These
tests are indicators of the extent of inflammation in liver.
In acute hepatitis, the enzyme level in blood can be up to
thousand units in chronic hepatitis.
Patterns of ALT (single peaks, double peaks and multiple
peaks) reflect progress of HC and its prognosis.
The pattern of ALT peaking and then gradually reducing
indicates remission. If
within the first 3 months of the disease, there are more instances
of double peaks or multiple peaks of ALT activity, there is a
tendency to be chronic.
Alkaline phosphatase/Gamma GTP
These
tests are indicators of inflammation in the bile ducts. They can
be elevated in hepatitis.
Gamma globulin
It
is elevated in hepatitis.
The first of these four tests are sometimes referred to as liver
function tests.
Detection
of `hepatitis C.
RIBA II.
Viral RNA (Measuring
hepatitis C virus in the blood.
It is more sensitive than RIBA II is.
Tests
for functioning of the liver
Protime (PT)
Measuring
ability of blood to
coagulate. It is elevated when the liver
does not synthesize enough of the ingredients that cause blood
to coagulate.
Albumin
A
serum protein synthesized by the liver.
It is low when a damaged liver
is not able to keep up with its synthesis.
Key words:
du/toxin:
a pathogen which has accumulated locally so that its influence is
intense"; it has no relation to "dirtiness
Qi:
Energy.
Differentiation: an analysis of
