HCV has also been found to be “indolent” in nature,
meaning the virus is slow to. This phenomenon appears to be
associated to a number of possibilities. Firstly, cellular
reproduction of HCV can and is influenced by the longevity of
the host cells therefore influencing reproduction processes.
Secondly, HCV is genetically unstable therefore the reproduction
process is predominantly faulty. HCV also tends to proliferated
in to a variety of weak virus particles often referred to as “virions”.
These HCV virons have different RNA structures and variations
that over an extended period of time partially develop into more
viable HCV RNA patterns thus spreading more vigorously as the
disease progresses. This could explain why many infected
individuals remain symptom free for such long periods of time
after contracting the disease.
Despite the ongoing investigations, opinions are many on the
absolute mechanism of indolence with others researchers
suggesting that the slow rate of HCV reproduction is more likely
to be influenced by the fact that the rate of infected cellular
destruction by the immune system is predetermined by it's
viability. In other words the rate at which infected cells are
destroyed may virions replicate in sites beyond the reach of
antibodies making it difficult for the phagocytic process to
occur.
In
comparison to other viruses, HCV is exceptionally tiny. It
circulates in particularly low amounts and is extremely
virulent. The virus is highly infectious and is easily passed on
where there is an opportunity via blood-blood contact. HCV is
also extremely resilient, making it difficult for the body to
kill. It is classified as an RNA virus meaning that its genetic
material is made up Ribo Nucleic Acid as opposed to DNA. It is
therefore less genetically stable than the DNA viruses and prone
to rapid mutation creating varieties of the HCV strain. The
various types are distinguished by variations in their genetic
map evolving into different strains which are largely, but not
exclusively, associated to various regional parts of the world.
HCV is also a fragile virus which mutates while present in
individual patients. This results in a high degree of
heterogeneity which is associated with greater resistance to
drug therapy. The longer the persistence of the infection the
more variations are likely to be present. This results in these
quasi species presenting a more complex problem to the immune
system.
Unlike hepatitis B, HCV is not a retrovirus. Retroviruses by their
nature, invade the host cells as well as attempt to integrate
their own genetic structure into that of the host cell. This of
course, causes further disruption and has the effect of
corrupting the healthy DNA and using the infected cells to
further the proliferation process.
Symptoms of Hepatitis C.
The general symptomatology of HCV is
not to dissimilar to that of "CFS" (ME) and where a case
presents with CFS type symptoms that have not been investigated
and who fall into a high risk category (eg.. IV drug users or
health workers), differential diagnosis may be required.
Generally speaking though, many infected individuals remain
symptom free or will experience only a few of the symptoms
discussed below that will come and go.
• Flu like illness with alternate with chills and fever.
• Pains in the liver region.
• Digestive and bowel disturbances (eg.. IBS, bloating, diarrhoea,
etc)
• Joint and muscle pains.
• Night sweats.
• Depression, mood swings and mental fatigue.
• Cognitive dysfunction.
• Chronic fatigue and/ or sudden attacks of exhaustion.
• Adverse reactions to alcohol.
• Frequent urination especially at night.
• Loss of appetite.
• Digestive disturbances
• Frequent or continuous headaches.
• Sleep disturbances.
• Chest pain and palpitations.
• Pronounced fluid retention.
• Itchy skin.
• Blood sugar irregularities
• Dizziness and peripheral vision problems.
• Small red patterns of inflamed blood vessels known as "Spider
Naevi".
• Irregular menses
• Severe premenstrual tension
• Lower libido.
Generally speaking, the majority of patients with chronic HCV
experience fluctuations in their sense of wellbeing. This is
sometimes reflected by the liver function tests, which often
demonstrate a classic pattern of sharply fluctuating liver
enzyme levels. However, these patterns do not necessarily
correlate to the severity of symptoms, and they are far from
being a conclusive indicator of liver damage.
Clinical Presentations and phases.
From a clinical perspective, the symptoms of HCV can be classified
into two categories. Firstly, the disease can both hepatotrophic
and lymphatotrophic thus causing progressive liver disease and
chronic lymphatic disorders. The second category is caused by
the disordered response by the immune system to the virus. This
category is also divided into two general types, autoimmune type
conditions which are bought about by the immune system attacking
body tissue and the second type being various ME or CFS like
syndromes which seem to affect a broader part of body function.
Generally speaking, very few people with HCV realise anything is
wrong with them at or around the time they contract the disease.
Unlike other forms of hepatits, less than 5% will suffering from
the classic acute symptoms such as jaundice, diarrhoea and
nausea. Even them the symptoms are mild.
As discussed, the majority of patients that contract HCV tend to
experience symptoms associated to the chronic form of the
disease. The rate at which infected patients go on to experience
these symptoms may vary considerably. For example, some
individuals develop serious problems within 5 years while others
take up to 13 to 15 years. Age appears to have a large influence
on the progression of the disease. Those who get infected later
in life tend to deteriorate more rapidly than those infected in
their youth. Those infected at a reasonably young age are more
likely to develop liver disease such as cirrhosis and liver
cancer as their life expectancy is much greater.
Interestingly, it is estimated that as many as 20% of those
exposed to HCV may have the ability to clear the virus. Some
individuals for example are antibody positive but PCR negative
(Polymerase Chain Reaction test) and therefore not currently
infected. This suggests that the Human Leucocyte Antigen (HLA)
of patients determines the likelihood of their being able to
mount a detectable T-cell mediated response to the virus. Not
all patients with HLA type manage to do this and it seems that
very few manage to have an immediate spontaneous response once
they have become chronically infected.
In clinical terms, HCV infection usually begins to cause problems
in the liver between 5 to 10 years after infection. It is
thought that some patients may not develop anything more serious
than mild liver disease throughout their lives, while a few
patients progress to cirrhosis within 5 years. There is some
anecdotal evidence to suggest that people who are infected in
later life deteriorate much more rapidly.
Patients with chronic hepatitis are sometimes classified according
to the degree and type of injury found in their livers. This is
relatively easy to assess in cases of Hepatitis B, where liver
function test results give reasonably accurate indications of
liver function and histological health. However, with HCV these
indicators unfortunately only give the practitioner a brief
glimpse of the possible damage created by the virus. Together
with this one could be experiencing little or no symptomatology
in relationship to the damage caused by the disease. Often liver
biopsy’s are recommend to accurately ascertain the true damage
to the liver.
Mortality rate.
In reality the quality of information is not yet good enough to
give accurate long term prognosis expectations of those
suffering from HCV. Keeping this in mind, information currently
available suggests that the mortality rate of HCV related liver
failure is estimated to be around 5 to 10% and more likely 7%.
However, it is important to note that this group often have
poorer health than others and a higher viral load than the
average. There are also a number of other variables which are
thought to influence the long term prognosis which are difficult
to measure. These include lifestyle factors such as diet,
exercise, etc (which are difficult to factor in to the
equation).
Cirrhosis
Cirrhosis of the liver also plays a large part in the long term
prognosis of a patient and can lead to a variety of additional
symptoms especially those associated to circulatory changes of
the blood. These can include the development of varices
(especially of the esophagus, which are indirectly caused by
poor blood flow through the liver), Encephalopathy, where by
patients may develop impaired mental function due to the liver
not breaking down waste products in the blood as efficiently as
it should or as an end result of the blood bypassing the liver.
These events can eventually cause the liver to fail.
As mentioned, Cirrhosis can lead to a variety of problems because
blood is unable to flow freely through the liver. The first
symptom is ascites, which is a swelling of the abdomen due to a
build up of fluid. This needs to be treated with a low salt
diet, and possibly a diuretic to help the kidneys excrete more
salt and water. The second problem is enlarged distended blood
vessels around the stomach and gullet. They tend to develop due
to blood trying to find its way around the scarred liver. When
this occurs, blood vessels tend to bleed into the stomach and
may require urgent treatment. The third problem, which is
fortunately rare, is the development of liver cancer, (hepatocellular
carcinoma. HCC).
There is also a possible pattern of differing natural history
according to the sex of the patient. For example, women may be
more susceptible to autoimmune phenomena, while men may
experience more severe liver problems. This may be linked to
menstruation in women and the level of iron in hepatocytes in
males.
Liver cancer
In the case of HCV patients it is often said that about 5% of
those with cirrhosis progress to HCC over the subsequent ten
years. If this is the case then 1 % of HCV patients may be
expected to develop HCC as against an average incidence of about
0.05% in Western countries. Thus HCV significantly increases the
likelihood of developing HCC. It is important to stress that
there is not yet enough data to provide exhaustive figures at
stage.
Lymphatic Disease
Although HCV frequently infects the lymphatic system this is
currently thought to cause few instances of serious illness.
However enlarged lymph nodes in the liver are detectable in most
chronic patients and many experience occasional sub clinical
symptoms of lymphatic infections such as swollen glands.
Autoimmune Disease
A number of autoimmune diseases are linked to hepatitis C,
although it should be stressed that apart from autoimmune
thyroid disease, their occurrence is quite sporadic. It may
affect perhaps 20% of patients at most during the course of the
disease and generally effecting females only. They include such
conditions as cryoglobulinemia, autoimmune thyroid disease,
autoimmune hepatitis, membrane proliferative glomerulonephritis,
polyarthritis, porphyria cutanea tarda,. Sjogrens syndrome etc
which can affect virtually all organs.
It also seems that a large number of other diseases may be
connected to HCV though they have not yet been scientifically
linked. Such diseases as systemic lupus erythematosus occur
suspiciously frequently in populations which are known to have
high incidences of HCV. Despite all the evidence, the
understanding of HCV and the development of autoimmune disease
is still not fully understood.
HCV & Myalgic Encephalomyelitis
(ME)
It is not uncommon for hepatitis C patients to have been
previously diagnosed as having M. E. (CFS). This does not
necessarily mean that they have been misdiagnosed since the two
conditions are not mutually exclusive. It would appear a
significant number of patients presenting with symptoms
definitely qualify as candidates for chronic fatigue syndrome.
Such symptoms as "problems with memory sequencing, spatial
disorganisation, trouble giving and following directions,
difficulty processing problems, slow intellectual speed,
difficulty processing visual and auditory information,
forgetfulness, irritability, mental confusion, inability to
concentrate, impairment of speech and/or reasoning, light
headedness, mental fogginess, word finding problems,
distractibility, difficulty processing more than one thing at a
time, inability to perform simple maths functions, problems with
verbal recall, related motor problems, disturbances in abstract
reasoning, sequencing problems, memory consolidation, short term
memory distortions, fatigue, etc", are all common experiences of
both groups of patients. Taking this into consideration and the
fact that symptoms are commonly shared between the two groups it
would be prudent to consider a differential diagnosis.
Especially where the suffer is in what is considered to be in
high risk life style situation. This would include IV drug
users, health care workers, etc.
Depression
Another common symptom is depression. Researchers hypothesises
that this may be linked to viraly induced disruption of
serotonin production. Other researchers have also speculated
that fatigue, depression and mental dysfunction associated to
the condition, may be caused by poor cerebral blood circulation.
HCV patients for example, undergoing interferon therapy and
complaining of depression, have been shown to suffer from poor
cerebral blood circulation. It is also generally accepted that
depression is linked to poor sleep quality, a symptom reported
by both groups of patients.
Transmission.
Generally speaking, HCV is transmitted via blood to blood contact.
Its is known to survive in dried blood for longer periods than
many other virus (eg. HIV). HCV is uncommonly small and often
inhabits blood cells. The virus will remain intact as long as
these cells remain in tact. Transmission is usually by the
following mechanisms. For example, patients can be infected by
via blood transfusions, operations and infected blood products.
The majority of cases though, at least in western countries, are
infected via intravenous drug use. This represents approximately
75% of all recorded cases.
Sexual transmission represents a small group of those infected
with the available information suggesting a very low rate of
sexual transmission regardless of the sex practiced.
Household contact may account for more cases than sexual
transmission (2%). Because the virus is so difficult to kill and
can be harbored in invisible films of blood the opportunities
for it to jump to a new host within the home can be high. This
may vary of course according to the practices of family members
and may be linked to cultural factors. For example, the
combination of bleeding gums and tooth brush sharing is a good
candidate for transmission. The use of the same razor by more
than one family member is another candidate for possible
transmission.
Occupational transmission represents about 2% of those who have
contracted HCV. Dentists who practice oral surgery and health
workers who administer intravenous injections are at an
increased risk. The percentage of mothers with HCV passing on
the virus to their child appears to be very low. It is likely
the point of transmission is via the birth process not via the
womb.
Blood tests for hepatitis C.
Generally speaking, the discovery of HCV normally occurs through
routine tests done on liver function (LFT'S). However they are
not always good indicators of the health of the liver in HCV
patients. Alanine aminotransferase (ALT) and aspartate
aminotranferase (AST) are the two most common indicators used
and when above normal range further investigation is instigated.
ALT is thought to be a more accurate reflection of liver
inflammation and health while AST indicators can sometimes be an
unreliable as it can be produced by other organs such as the
heart.
Alkaline phosphatase is the test most often used to detect
obstruction of the bilary system, though it can be associated to
progressive liver disease.
Bilirubin, a bile pigment usually extracted from the blood by the
liver can also indicate a decreased efficiency of the liver.
Albumin, a major protein found in the blood generally
corresponds to the livers effectiveness in forming protein. Low
levels usually indicate problems with protein synthesis which
can correspond to liver damage. Prothrombin time is a test which
assesses the efficiency of blood clotting. When the liver is
damaged it may fail to produce blood clotting factors.
Viral load testing also plays a big part in the detection of the
disease. These include a variety of antibody detection and virus
detection tests that indicate the presence or absence of HCV
itself in the blood or other body tissue.
These include such tests as the ELISA Ill (Enzyme liked
Immunosorbent Assay) and the RIBA (Recombinant Immunoblot Assay
III) which are used to confirm the presence of HCV antibodies.
RIBA (Recombinant Immunoblot Assay III) is seen as a highly
accurate test but still cannot be reliable to 100%. Because the
RIBA Ill test is more expensive than ELISA it tends to be used
as confirmatory tool.
The matrix test is another variation on the antibody test using a
prodedure which uses a technique known as "in vitro enzyme dot
blot immunoassay" and considered to be highly accurate.
Unfortunately, it takes up to six months for antibodies to HCV
to form in the blood. People seeking an early diagnosis after a
suspected exposure should seek retesting after six months of the
initial antibody test.
Virus detection and analysis tests try to assess the presence or
absence of HCV itself . They are more definative than the
antibody tests but usually more expensive to their sophisticated
detecting minute traces of any organic substance in any given
medium (in this case blood). In the case of HCV it works by
taking a sample of blood from the patient being tested and
amplifying the nucleic acid associated with the virus many
millions of times. This brings the detectable levels up enabling
experience technicians to assess how much of the original
material is present in the sample. Although PCR has limitations,
it is probably the most useful single test. The b-DNA test for
HCV, which is sometimes referred to as Quantiplex tests,
searches for the presence of the virus in the blood but is less
sensitive than the PCR test. It generates an estimate of viral
loads above a certain level.
Nutritional and dietary
considerations.
Diet is an essential but controversial issued for HCV suffers.
Dietary recommendations vary from one nutritional expert to the
next and are handed out to patients with frequency resulting in
a sense of confusion and despondency. More often than not,
unhealthy diets rich in fats, carbohydrates and sugars are
commonly consumed by newly diagnosed patients which only
contribute to the over all sense of sickness. On the other hand,
there is also a group of individuals who adopt extremely strict
health diets prior to diagnosis, knowing that something is wrong
but not being able to identify the problem.
From a perspective of the patient, Its important that each
individual appreciate that chronic HCV is a dynamic condition
associated with a number of varied clinical profiles. It would
therefore be safe to say that there is no such thing as
"Hepatitis C DieC. For example, a patient with normal liver
enzymes and a good appetite will have very different
requirements to one who is under weight and has advance
cirrhosis of the liver.
Keeping this in mind, some basic nutritional understandings need
to be considered. For example, protein plays a vital part in
many metobolic functions in the body and therefore considered an
important part of the diet. As the liver plays a unique role in
protein metabolism any impairment of the liver may influence the
production of such substances as albumin, prothrombin and
transferrin. Therefore, cutting back on protein will result in
insufficient building blocks being available to the liver for
protein production and may over an extended period of time, as
shown in experimental animal studies, lead to hepatitic necrosis
and fibrosis.
The importance of adequate protein in the diet to proper immune
function is also another consideration. For example, the most
severe effects of protein malnutrition are on cell mediated
immunity, although all facets of the immune function are
ultimately effected.
The other side of the protein debate is the type of proteins to be
considered. It is well understood by the experienced clinician
that heavy red meat protein for example can labour a weakening
digestive system. Typically HCV suffers experience many symptoms
associated to this particular problem and purely from a point of
view of comfort it may be best avoided. If protein digestion
remains a problem after dietary intervention, Betain
Hydrochloric Acid may have to be considered. Papain, an extract
of papaya will also assist in the digestive process.
Supporting the reduction of red meat in the diet for HCV sufferer
is the view that iron in too high a level can cause increased
concentrations of sustainable iron deposits in liver cells. This
is mainly due to fact that HCV suffers have a reduction in liver
iron loss due to hepatic damage caused by the virus. Therefore,
low levels of iron rich food decrease the possibility of hepatic
build up which can lead to further complications.
Carbohydrates are another important issue to be addressed as they
play an important role in the energy production process. Keeping
this in mind, many individuals with HCV suffer from a range of
symptoms associated to poor carbohydrate digestion and
assimilation. To further complicate the issue there is generally
an increase potential for gut dysbiosis and leaky gut syndrome.
Generally speaking, these conditions are possibly due more
towards lifestyle and eating habits than the disease it self.
For example, bloating and abdominal discomfort are commonly
experienced when refined carbohydrates and/or yeast containing
foods are consumed, though not an uncommon experience when more
complex carbohydrates are included as a part of the diet. This
in turn often leads to further depress energy levels as well as
increased feelings of depression. Reductions in symptoms can be
reduced by modifying the intake of refined carbohydrates and
yeast based foods such as breads, etc. Pancreatic enzyme
supplements can be taken after each meal. In many cases this
simple approach can have a positive impact on not only the
symptomatology associated to gut dysfunction, but also on the
energy levels of the sufferer. Gut dysbiosis should also be
addressed with prebiotic and probiotic therapy combined with
treatment protocols for gut repair.
As far as carbohydrate consumption is concern, there are also
those who have trouble maintaining their body weight. A low
carbohydrate diet could very well contribute to substantial
weight loss and a reduction in available energy in these
individuals. Underlying food intolerances will also contribute
to poor nutritional uptake impacting on weight. The damaged
liver also has to be considered as a contributing factor in
maintaining weight as it plays such a vital role in energy
metabolism. As as shown in numerous experimental studies for
example, where there is chronic liver injury there is less
glycogen stores in the liver. This in turn forces the body to
use other energy sources therefore increasing the breakdown of
protein and fats to provide energy which causes weight loss and
in time muscle wasting.
Dietary fats are an important factor in the well being of those
suffering from HCV. Saturated fats for example will often cause
nausea and uncomfortable digestive responses. Even those who
have asymptomatic responses to saturated fat consumption
increase risk of developing fatty infiltration and or stasis of
bile in the liver and gallbladder. High levels of saturated fats
will also influence an already weakened digestive system and as
well as cause long term abnormalities in liver function and
health. Increased blood levels of cholesterol, free fatty acids,
triglycerides and bile acids also inhibit various immune
functions including the ability of lymphocytes proliferate and
produce antibodies. The ability of neutrophils to migrate to
areas of infection and engulf and destroy infectious organisms
are also impaired. Alternatively when taken in moderation, oils
containing eicosapentaenoic acids (EPA), linolenic and linoleic
acid which are found predominantly in cold water fish, Flaxseed
and Evening Primrose Oil do not cause liver abnormalities or
have an adverse effect on the immune function and will
contribute to the overall wellbeing of the individual.
Sodium consumption is another factor that needs to be taken into
consideration. Sodium should be reduced in the diet of those
suffering from HCV, especially where there is an abnormal
accumulation of fluid retention in the abdomen (ascities). This
commonly occurs in states of advance cirrhosis and should be
taken seriously. Patients without ascites should not over
indulge in table salt, although their restrictions may not be as
severe.
Aflatoxins are also thought to be a co-factor in contributing to
liver stress and damage. These substances are produced by fungi
which grow on nuts stored in hot and humid conditions and it
advised that patients with HCV avoid all nuts, especially
peanuts.
Sugar
Sugar consumption, even in small amounts, can impair immune
function. This appears to be due to the fact that glucose (blood
sugar) and vitamin C compete for transport sites into the white
blood cells. Decreased vitamin C levels due to excessive sugar
consumption may result in a significant reduction in white blood
cell function. This is based on evidence that vitamin C and
glucose appear to have opposite effects on immune function and
the fact that both require insulin for membrane transport into
many tissues.
Studies have shown for example, the ingestion of 100 gram portions
of carbohydrate as glucose, significantly reduced the ability of
neutrophils to engulf and destroy bacteria. In contrast, the
ingestion of 100 grams of starch had no effect. These effects
started less than 30 minutes after ingestion and lasted from two
to five hours. Typically there was at least a 50 per cent
reduction in neutrophil activity two hours after ingestion.
Since neutrophils constitute 60 -70 per cent of the total
circulating white blood cells, impairment of their activity
leads to depressed immunity.
In addition, ingestion of 75 grams of glucose has
also been shown to depress lymphocyte activity. Other parameters
of immune function are also undoubtedly affected by sugar
consumption.
Alcohol
Alcohol is a potent toxin to the liver. Increasing evidence has
shown that alcohol intaken by individuals suffering from HVC
have an increased risk of cirrhosis of the liver. A combination
of alcohol and HCV has been shown to accelerate the progression
of the disease.
Iron
The liver plays an important role in the metabolism of iron and is
the primary storage organ. The average daily diet contains
approximately 10 to 20mg of iron daily with about 10% of this
iron being eliminated from the body. Patients with Hepatitis C
also have increased difficulty excreting iron and as a result,
can be venerable to the possibility of hepatitic overload. As a
consequence of this, iron overload can cause liver damage as
well as increase the overall deterioration rate of the organ.
Iron over load also reduces the response rate of the immune
system in patients with Hepatitis C. Evidence suggest the iron
over load may also contribute to the reduction in response rate
of immune building therapy including the use of herbs.
Iron supplementation therefore should be avoided. Iron rich foods
such red meat, liver, cereals fortified with iron reduced while
iron and iron coated utensils replaced. Levels of organic iron
found in dark green leaf plants such as spinach and parsley have
been found not to contribute to iron overload.
Overweight
Being over weight can increase abnormalities related to the liver
in individuals suffering from HCV. These include elevated ALT
and AST readings (against those who are of normal weight with
HCV), fatty deposits in the liver (steatosis), fatty
inflammation and fatty cirrhosis. Studies suggest that over
weight individuals with fatty liver related conditions and
Hepatitis C who reduce weight have liver related abnormalities
improve.
Summary
Diet obviously plays an important role in the long term management
of HCV. Foods should be fresh, of good quality, and rich in
vitamins and minerals. Include plenty of low fat proteins as
well as suitable live yogurt cultures where no dairy sensitivity
exists. Freshly squeezed vegetable and fruit juices can be taken
daily and plenty of purified water consumed. Fried and highly
heated oils should be avoided while oils such as oilve oil,
flaxseed and omega 3 oils be included in the daily menu. Alcohol
is to be avoided where possible coffee, table salt, nuts,
especially peanuts, sugar, carbonated and glucose fortified
drinks, chocolate, food additive and artificial colours.
Herbal, Vitamin and Mineral
Considerations.
Herbs, vitamins and minerals play an important role in the
management of HCV. They will in time have a positive impact on
viral load and liver assays as well as the general health of the
sufferer, especially where diligence is applied. While most
people with HCV will require on going treatment this is not a
reflect on the efficacy of the herb and nutrients but rather a
reflection on the nature of the disease itself. Most sufferers
at some stage will be addressing a range of symptoms and health
difficulties with natural healthcare playing an important roll
in treatment protocols during these various stages.
St Marys Thistle (Silybum marianum)
The biological activity of silymarin and silybin in particular has
been the subject of numerous scientific studies. Early interest
focused on the hepatoprotective activity of silymarin against
liver damage caused by carbon tetrachloride (M4) and the Amanita
mushroom poisons. Subsequently, the hepatoprotective action of
silymarin was shown also to extend to ethanol and other types of
poisoning. The principal mechanism underlying the
hepatoprotective effects of milk thistle and silymarin is a
protective effect on the cell membrane, mediated by a strong
free radical scavenging and antioxidant action. Silymarin has
been found to protect against ethanol- induced hepatic lipid
peroxidation by increasing hepatic glutathione levels, as well
as increasing superoxide dismutase (SOD) expression and activity
in cells taken from patients with chronic liver disease. Silybin
has been shown to increase the activity of both SOD and
glutathione peroxidase in human erythrocytes.
Silybin can accelerate the regeneration of hepatocytes in damaged
livers through activation of the DNA-dependent RNA polymerase,
resulting in an increased rate of protein synthesis and mitosis.
Silybin did not stimulate proliferation of fast growing cell
lines (hepatoma cells, Hela and Burkitt lymphoma cell lines) in
vitro, a finding that alleviates concern that milk thistle might
stimulate the proliferation of malignancies.
Empirically, the herb is well documented. This is especially so in
Europe (mainly Germany), where Silymarin concentrates have been
used extensively by the medical profession for the treatment of
liver disease and jaundice. Histological, clinical and
laboratory findings in both human and animal studies, have shown
silymarin to have a beneficial effect in the treatment of the
following disorders. Alcohol and chemical induced fatty liver,
Chronic viral hepatitis (of all types), Cirrhosis, Viral and
chemical induced hepatic damage, and Jaundice. Based on the
information provided by clinical research and studies to date,
Silymarin marianum provides a safe alternative in the management
and treatment of liver disease.
Dandelion Root. (Taraxacum
officinale)
The common dandelion (root) is recognised by herbalists all over
the world as an excellent liver remedy. It is rich in many
nutrients, being particularly high in vitamins, minerals,
protein, choline, inulin and pectin's. Studies in humans and
laboratory animals have shown that dandelion enhances the flow
of bile, improving such conditions as liver congestion, bile
duct inflammation, hepatitis and jaundice. Together with this,
the herb has a positive impact on digestion. This is due to the
bitter aspect of the herb which stimulates taste buds in the
mouth. Their stimulation leads to the release from the gut wall
into the blood stream of gastrin. Some bitters have not only
been found to stimulate appetite and digestion through this
mechanism, but also stimulate the liver and bile flow.
Dandelion's beneficial effects on such a wide variety of
conditions is probably closely related to its ability to improve
the functional capacity of the liver.
Dandelion has also been found to stimulate the elimination of bile
from the liver. This is a very important property in that if
bile is not being eliminated from the liver, the liver is at
increased risk of damage. Clearing of bile from the liver is
very important in the treatment Hepatitis and other liver
diseases since it assists the decongestion of the liver.
The primary therapeutic actions of dandelion are due to the bitter
principle taraxacin and inujin (bitter glycosides). Other
constituents include resin, levulin, pectin, taraxanthin,
sesquiterpenes, fatty acids, flavonoids, vitamins and mineral
salts.
Astragalus. (Astragalus membranaceus)
Astragalus is a highly valued Chinese herbal tonic. Like Ginseng,
its pharmacological properties are varied including immuno-
potentiating effects, anti-bacterial and anti-viral properties,
the ability to promote nucleic acid synthesis in the liver and
spleen, hepatoprotective, anti- inflammatory activity,
cardiovascular tonic effects such as hypotensive and
vasodilatory action as well as a possible blood glucose
balancing action. The herb has also been found to increase
superoxide dismutase activity thus acting as a powerful
anti-oxidant as well as promoting cartilage growth in vitro.
Experiments also show astragalus to be liver cell protective in
laboratory induced hepatitis by preventing liver glycogen
reduction caused by carbon tetrachloride exposure. In
conjunction with Silybum marianum (St Marys Thistle), it would
appear that astragalus, with its anti-viral and liver protective
action, may contribute many benefits in the treatment of
Hepatitis C. Together with the above actions, other research has
found that the herb to be very useful in the treatment of kidney
disease having the ability to reduce urinary protein in chronic
and acute nephritis. These effects appear to be mainly due to
the saponins and polysaccharides found in the herb.
Whole root extracts have also been shown to have a profound effect
on phagocytic and macrophage activity. In a variety of studies
involving mice, Astragalus was shown to enhance phagocytic
activity and increase super-oxide production and acid
phosphatase activity of peritoneal macrophages. These benefits
appear to also be passed onto the humoral immunity. Oral doses
of the dried extract when given to humans were shown to increase
levels of anti- bodies such as lgE and lgM. In another study,
two months of oral treatment in subjects susceptible to the
common cold, greatly increased levels of lgA and IgG in nasal
secretions. Oral doses of Astragalus were also found to increase
serum levels of IgG as well as conversion percentage of
lymphocytes when given to mice.
The herb has also been observed to exert a marked antiviral
action. This is most likely to be due to increased immunity and
possibly the enhancement of interferon production. Together with
this observation, numerous studies have shown protective effects
of Astragalus with both parainfluenza virus type 1 and Coxsackie
B virus infection of myocardial cells in vitro and vivo after
injection. In vitro, studies have also confirmed that the herb
has anti-microbial effects against Shingella dysenteriae,
Streptococcus haemolyticus, Diploccus pneumonia and
Staphylococcus aureus.
Cordyceps
Historically, Cordyceps has been used to soothe the lungs,
replenish the kidney, arrest bleeding and resolve phlegm.
According to Traditional Chinese Medicine philosophy, the effect
of cordyceps runs through the lung and the kidney meridians. It
is said to have a positive impact on deficiency syndromes of the
lung, phthisical (tuberculosis) cough and haemoptysis (cough
containing blood), deficiency of yang (vital function) of the
kidney as well as seminal emission and premature ejaculation.
Cordyceps is also said to promote vital energy which can be
given to patients recovering from weakness caused by severe
illness and persons of advanced age. Cordyceps is well known for
its effect in strengthening the body and restoring energy.
Cordyceps has also been employed as a tonic for strengthening the
testes and ovaries acting as an aid in fertility . Nocturnal
emissions have been also treated with the herb. Other actions
attributed to cordyceps are homeostatic, laxative (especially in
chronic constipation), and as a sedative and support for the
adrenal glands.
More modern interpretations centre around the herb's effects on
the respiratory system (specifically the lungs), the kidneys,
immune system, liver and the glandular system.
Since the 1980's, pharmacologists have succeeded in defining the
herbs constituents into several unique substances. These include
such constituents as Coryceps essence, Cordyceps acid,
glycocordy cepiglycan, cordycepin, glutamic acid, phenylalanine,
proline, histadine, valine, oxyvaline, arginine, alanine,
adenosine, d-mannitol and vitamin B12. Some of the substances
have been found to improve the immune function within the human
body and reinforce the resistance to various pathogenic bacteria
and tumors. Studies have also attributed the herb to other
pharmacological actions with effects being observed on the body
including the nervous, respiratory, immune, cardiovascular,
glandular systems and the liver.
In one particular study for example, patients with liver cirrhosis
were given a combination of cordyceps and peach seeds (prunus
persica). Following treatment with the herbal combination, low
immune cell functions in the cirrhosis patients were improved
with Helper T-cells, suppressor-T cells, Natural Killer cell (NK)
function, and serum levels of complement returning
to normal. Researchers concluded that the herbal treatment may be
useful in preventing cellular decay of the liver an issue which
is of great importance to those suffering from HCV.
Research studies have als shown that Cordyceps stimulates the
growth of such active cells as T-cell, NK cell, mononuclear
macrophagocyte as well enhance the secretion of various
lymphokines. The immune system compounds in cordyceps
responsible for this action are the polysaccharides. With the
impact of Cordyceps on the body, it appears from a variety of
studies that the vitality of NK-cells can be increased and the
phagocytosis percentage of the mononuclear macrophagocyte can be
raised. The herb has also been found to stimulate an increase in
immunoglobulins G and M along.
Cordyceps has also been shown to help lower high serum cholesterol
levels which commonly occurs in those suffering from HCV. In a
large, well controlled clinical trial in China, researchers
found that cordyceps caused a significant lowing of cholesterol
(LIDIL, total cholesterol and total tryglycerides). It was also
observed that all the patients in the trial had a significant
elevation of high density lipoprotein (HIDIL). The patients
received 330rng of cordyceps three times daily for sixty days.
Bupleurum falcatum.
Bupleurum root is an important component of a variety of TCM
formulations particularly in remedies for inflammatory
conditions. The main active ingredient of Bupleurum are
steroidal-like compounds known as saikosaponins. These compounds
have diverse pharmacological activity including significant
anti-inflammatory action. Bupleurum saikosaponins have other
therapeutic activities which include lowering cholesterol
levels, preventing liver damage, improving liver functions in
chronic hepatitis and mild sedativelpain relieving action on the
central nervous system.
The anti-inflammatory activity of the saikosaponins seems to be
related to an increase in the release of glucocorticoid hormones
by the adrenal gland. This release of glucocorticoids by the
adrenal gland is stimulated by the pituitary hormone
adrenocorticotropic hormone (ACTH). Bupleurum thus increases the
release of glucocorticoids by increasing the pituitary release
of ACTH in turn increasing the functional ability of the adrenal
cortex.
Over recent years scientific interest has grown sustantially in
the possible use of Bulpeurum in the management of viral induced
liver disease. A number of clinical trials using Bupleurum in
chronic active hepatitis using oral doses of saikosaponins at a
low dose showed reductions of serum liver enzymes over a period
of time. This resulted in statistically significant changes at
3, 6 and 12 months. Other studies showed satisfactory results
both in acute hepatitis and chronic hepatitis with good clinical
results reported.
Chinese or Korean Ginseng (Panax
Ginseng).
Perhaps the most famous medicinal plant in Chinese Medicine is
Panax Ginseng the herb has been traditionally used to restore
and tonify the "yang" or warmth quality within the body. It is a
sweet, slightly bitter and warm herb, replenishing the vital
energy of the body and increasing the production of body fluids.
It has been used for centuries as a tonic for it's revitalising
properties, especially after long illness.
Classified as an adaptogen by Western Herbal standards, the term
denotes a common quality of many herbal remedies. It is this
adaptogenic effect of ginseng that gives the herb it's
reputation, realising it's potential as a general tonic,
especially in debilitated and feeble individuals.
Ginseng posses immuno stimulating activity, as evidenced by its
ability to enhance antibody response, cell mediated immunity,
natural killer cell activity, the production of interferon, and
lymphocyte and reticulendothelial system proliferate and
phagocytic viability. Studies using Ginseng have also found the
herb prevented viral infections in animals, presumably due to
the combination of its immuno stimulating effects. Together with
this, enhancement of cellular proliferation and function was
shown on a variety of cell types including epithelial, hepatic,
lymphocyte, fibroblast, thymic and neural cells.
Research studies an animals have confirmed the possible use of
Ginseng in the treatment of hepatic disease. The studies are
promising but have yet to be confirmed by clinical trials. To
date, scientists have found Ginseng affects the liver in several
ways. Firstly, ginseng enhances the activity of the livers
specialised macrophages known as Kupffer cells. Secondly, it has
being shown that the herb enhances hepatic protein synthesis
which would be extremely beneficial for the elderly where this
synthesis process is often reduced. Finally, Ginseng has also
been shown to reverse diet-induced fatty liver as well as
possessing significant protection to the liver against damage to
chemicals. The clinical implications for the use of the herb in
the treatment of hepatic disease are quite broad and support its
use as a general tonic.
Pharmacologically speaking, ginseng is classified as an adaptogen,
enhancing the ability of the body to cope with various
stressors, both physical and mental. It's complex chemistry
appears to act mainly on the hypothalamus, resulting in a
sparing action on the adrenal cortex which is believed to be
mediated through the anterior pituitary and Adrenocorticotropic
Hormone (ACTH) release. This action, thus regulates the adrenal
cortex response, so that the first phase of the body's
non-specific response to stress is more efficient. This means
that the response is stronger and quicker with the feedback
control mechanism being more effective. As a result,
glucocorticoid steroid levels return more rapidly back to normal
as the stress decreases. During more prolonged stress or adrenal
demand, it has been found that glucocorticoid production is
reduced by the herb, while at the time increasing adrenal
capacity. Numerous studies over the last forty years have
confirmed the herbs use as a medicinal agent for the treatment
of fatigue, enhancement of mental performance and general well
being.
Slippery Elm. (Ulmus rubra, U.
fulva)
Mild to moderate inflammatory bowel complaints are common among
those suffering from HCV. Slippery elm will often provide relief
from uncomfortable abdominal discomfort and pain, soothing the
irritated gastrointestinal mucosa of the stomach and small
intestines. The herb is classically referred to as a demulcent
having additional nutrient qualities. It has an affinity with
most gut complaints and an affinity for the mucous membrane of
the gastrointestinal tract. The key action of the herb is its
mucilage action on the surface with which it comes in direct
contact where the herb produces a coating of slime, so to speak,
that acts to sooth and protect exposed surfaces.
This explains why the herb historically has a long use in
gastrointestinal inflammations, lesions and ulcers. Slippery elm
has also been found to reduce the irritant symptoms associated
to excessive stomach acids or digestive juice secretions.
Slippery elm powder, for example, is a very popular remedy for
relieving the effects of acid dyspepsia or gastric reflux after
a heavy meal.
From an active constituent point of view, slippery elm has no real
pharmacological action in the body and is used mainly for its
mucilage effects. Research into the herb has found a variety of
constituents in low levels which include galactose, 3-methyl
galactose, rhamose and glacturonic acid residues.
Vitamin A
Vitamin A should be used carefully as excessive use of the
supplementation can exert a toxic effect and cause damage to the
liver. Doses over 2,500 daily should be avoided.
Vitamin B Complex.
The B complex group of vitamins are involved in hundreds of
biochemical functions and reactions in the body. Where the diet
is poor or deficient, vitamin B deficiencies become obvious and
include tiredness, irritability, nervousness, and depression. A
poor appetite, insomnia, anemia, constipation or high
cholesterol can also be indicators of vitamin B deficiency. They
are an active group of vitamins in that they provide the body
with energy, basically by converting carbohydrates into glucose.
They are also vital in the metabolism of fats and protein and
necessary for the normal function of the nervous system. They
are essential for the maintenance of muscle tone in the
gastrointestinal tract and for the health of the skin, hair,
eyes, mouth and liver. For example , vitamin B complex is
important for the liver, in that it supports the cytochrome P450
system, which governs the liver's detoxification process.
Vitamin B12 has also been found to be important to hepatitis
suffers in that even when serum levels of B12 are normal the
diseased liver of these individuals is unable to absorb the
vitamin normally from the serum.
The requirements for vitamin B complex vary from one individual to
the next. For individuals with chronic illness such as those
suffering from hepatitis C, high dose B complex can be useful
for improving general health, energy, and stamina. High doses of
oral vitamin B complex in some individuals may cause nausea or
headaches. In these cases low dose vitamin B therapy may be
tolerated.
Vitamin C
Vitamin C functions biochemically as an antioxidant. It is
required for the hydroxylation of proline to hydroxyprolione
which is a step in the synthesis of collagen, the protein of
connective tissue and intracellular cementing substances.
Collagen is important in maintaining the health of bones, teeth,
gums, cartilage, capillaries, connective tissue and the healing
of wounds and fractures. Vitamin C is also required for the
synthesis of serotonin, noradrenaline and certain steroid
hormones. It promotes the absorption of iron, maintaining the
immune system and the normalisation of cholesterol.
Vitamin C has a long history in the treatment of viruses.
Biological studies have confirmed that the concentrate of
ascorbate in leukocytes is one of the highest known in the body
and is considered to be second only to that found in the
adrenals. These high concentrations within the leukocytes are
rapidly depleted by acute disease, infection and trauma, which
indicate a high requirement for the vitamin during a disease
state.
In clinical studies, large doses of vitamin C (40 to 1 0Ograms
orally or intravenous) were found to improve acute viral
hepatitis substantially within two to four days, while clearing
the symptoms of jaundice within six days. Other studies found
similar results, though one particular controlled study failed
to confirm and validate similar effects claimed of vitamin C.
However, Linus Pauling and colleagues claimed that systematic
errors invalidated this study. In another controlled study, the
researchers found that 2 grams or more of vitamin C per day
appeared to increase resistance in hospitalised patients to
hepatitis B. While 7% of the control patients developed
hepatitis, none of the treated patients did.
From the perspective of chronic liver disease, patients with
cirrhosis of the liver and Hepatitis C have an increased
potential for the development of high concentrations of
sustainable iron deposits in liver cells. This in turn can
contribute to a rapid depletion in health and the long term
survival rate of individuals with the disease, especially those
who are experiencing cirrhosis of the liver. As high doses of
vitamin C taken for long periods of time increases the potential
for iron uptake it is recommended that doses above 500 mg daily
not be taken unless for the management of acute symptoms.
Vitamin E
Vitamin E, also known as tocopherol is a powerful anti oxidant. It
is particularly useful in combating fatigue, as well as
supporting the immune system. Together with this it is thought
to boost cell mediated immunity . Vitamin E deficiency is also
been found to be linked to cirrhosis of the liver and poor
metabolism of fats. It works closely with selenium to assist in
some of the bodies metabolic actions.
Its capacity to reduce oxidative stress in patients with HCV has
attracted the attention of researchers. There appears to be
clear evidence that vitamin E prevents molecular changes which
are associated to with the development of cirrhosis of the
liver. Together with this, the research has been providing
insights into the molecular mechanisms of fibrogenesis as well
as the potential therapeutic approaches for patients with
chronic hepatitis C
Lactobacillus Acidophilus.
The microflora of the gastrointestinal tract has been described as
a complex ecosystem consisting of anaerobic and aerobic
micro-organisms. When gastrointestinal dysbiosis occurs in
individuals with HCV, a variety of gut disturbances can dominate
the health of the individual. These symptoms of course are
generally not associated to the disease itself, but certainly a
by product of the overall ill health of the individuals
concerned. Re-establishment of proper bowel micro flora,
especially using Lactobacillus acidophilus, therefore becomes
crucial.
Probiotics of this type, work by adhering to specific receptors on
the mucosal cells of the small and large intestine. As a result
they tend to suppress the attachment of other bacteria that
causes gastrointestinal imbalance. They also inhibit the
proliferation of less beneficial bacteria by creating an acid
environment through the production of acetic, formic and lactic
acids. In hepatic encephalopathy, the administration of
lactobacillus alter bacterial flora by lowering the number of
gram-negative rods which produce ammonia and amines.
Other beneficial effects of probiotics include improving the
production of factors which have anti- tumour activity, the
inhabiting of cholesterol production, the suppression of toxin
production by putrefactive bacteria in the intestine, the
reduction of beta-glucosidase and other enzyme activity, and the
production of natural antibiotics which are active against a
wide variety of gram- positive and gram -negative organisms.
Lactobacillus acidophilus has also been shown to inhibit the
formation of germtubes by candida albicans which in turn
contributes to minimise the invasive action of candida of the
throat, intestine and vaginal epithelium.
Other Beneficial Supplementation.
Bifidobacterium Longum
Bifidobacterium longum is an inhabitant of the large intestine. It
aids in the production of B-complex vitamins as well as provide
nutrients for liver health. Bifidobacterium is involved in the
inhibition of invading opportunistic microorganisms such as
bacteria and yeast, deterring their reproduction and
colonisation. It competes for both nutrients and receptor sites
along the large bowel wall preventing pathogenic invasions.
Together with this, bifidobacteria produce acids that lower the
pH resulting in an increase in acidity in the region. Low pH
balances impact on the capacity of harmful bacteria to
proliferate as they prefer a more alkaline environment. This in
turn effects the number of undesirable bacteria proliferating
resulting in a reduction in the conversion of nitrates which are
normally found in food being converted to carcinogenic nitrites
in gastrointestinal tract.
Choline
Choline is considered to be one of the B-complex vitamins. It
functions with inositol as a basic constituent of lecithin. The
richest source of choline is lecithin. Choline appears to be
associated primarily with the utilization of fats and
cholesterol in the body. It prevents fats from accumulating in
the liver and facilitates the movement of fats into the cells.
Choline combines with fatty acids and phosphoric acid within the
liver to form lecithin and is essential for the health of the
liver and kidneys. Choline is also essential for the health of
the myelin sheaths of the nerves and therefore plays an
important role in the transmission of the nerve impulses. It
also helps to regulate and improve liver and gallbladder
function thus assisting in the prevention of gallstones.
Folic Acid.
Folic acid functions as a coenzyme with vitamins B12 and vitamin C
in the breakdown and utilization of proteins. Folic acid
performs its basic role as a carbon carrier in the formation of
heme, the iron containing protein found in hemoglobin which
necessary for the formation of red blood cells. It also is
needed for the formation of nucleic acid, which is essential for
the processes of growth and reproduction of all body cells.
Folic acid is necessary for proper brain function, being
concentrated in the spinal and extracellular fluids being
essential for mental and emotional health. It also increases the
appetite and stimulates the production of hydrochloric acid. In
addition, it aids in performance of the liver.
Inositol
Inositol is closely associated with choline and biotin. Like
choline, Inositol is found in high concentrations in lecithin.
Vitamins B6, folic acid, pantothenic acid, and PABA also have a
close working association with inositol. Inositol is effective
in promoting the body's production of lecithin. Fats are moved
from the liver to the cells with the aid of lecithin; therefore
inositol aids in the metabolism of fats and helps reduce blood
cholesterol. In combination with choline, it prevents the fatty
hardening of arteries and protects the liver, kidneys, and
heart. Large quantities of inositol are found in the spinal cord
nerves and in the brain and cerebral spinal fluid and needed for
the growth and survival of cells in bone marrow, eye membranes,
and the intestines.
Magnesium
As discussed, digestion is often poor amongst those who suffer
from HCV and as result magnesium levels may be depressed.
Magnesium is an essential mineral that is involved in many
essential metabolic processess. Primarily, most magnesium is
found inside the cell where it activates enzymes necessary for
the metabolism of carbohydrates and amino acids. By countering
the stimulative effect of calcium, magnesium plays an important
role in neuromuscular contractions. It also helps regulate the
acid-alkaline balance in the body. Magnesium helps promote
absorption and metabolism of other minerals, such as calcium,
phosphorus, sodium, and potassium. It also helps the body
utilize vitamin B complex, vitamins C and E in the body. It aids
during bone growth and is necessary for proper functioning of
the nerves and muscles, including those of the heart. Sufficient
amounts of magnesium are needed in the conversion of blood sugar
into energy.
Magnesium deficiency can occur in patients with diabetes,
pancreatitis, chronic alcoholism, cirrhosis of the liver,
arteriosclerosis, kidney malfunction, a high-carbohydrate diet,
or severe malabsorption. Symptoms of magnesium deficiency may
include apprehensiveness, muscle twitch, tremors, confusion,
irregular heart rhythm, depression, irritability, and
disorientation.
Zinc
Zinc is one of the most important minerals for the immune system
as it is involved in so many immune mechanisms. These include
both cell-mediated and anti body-mediated immunity, thymus gland
function and thymus hormone action. When zinc levels are low the
number of T cells through out the body is reduced, thymic
hormone levels are lower and many white blood functions critical
to the immune response are severely lacking. All of these
effects are reversible upon adequate zinc administration and
absorption.
Chlorella and Spirulina.
An excellent source of numerous
micro nutrients rich in vitamins, minerals, amino and fatty
acids. It contains a range of substances that are thought to be
good for the immune system, blood and the liver, as well as
being partially rich in detoxification agents. It may be
particularly useful to vegetarians as it contains such nutrients
as B12 which may deficient in their diet.
