Liver Disease
by Dr. Sandra Cabot
The liver has everything to do with how we live, that’s why it is called
the liver. The state of your liver will have a huge bearing upon how
well you live, how long you will live and how you will look and feel.
In today's world, the liver has to work harder than ever before, and
all over the world we find that liver problems are increasing. Globally,
one in every ten persons suffers with some type of liver, bile duct
or gall bladder disease. Liver cancer is one of the most common cancers
in men and has a poor outlook.
350 million people worldwide suffer from hepatitis B which kills more
than 2 million annually. Hepatitis C is the most rapidly spreading infectious
disease in many countries and is a time bomb waiting to explode. These
problems are increasing, and thousands of people are waiting anxiously
for liver transplants that many of them will never be lucky enough to
receive. There are 25 million Americans with liver disease with thousands
waiting for liver transplants. Unfortunately there are not nearly enough
donor livers to meet the ever-increasing demand and so more than ever
the message is that we need to take care of our livers from an early
age. Thankfully nutritional medicine has been able to give many people
with liver disease, from hepatitis B and C, to auto-immune disease,
a healthy normally functioning liver. It is never too late as the liver
has remarkable powers of healing and regeneration.
A number of diseases can affect the liver such as acute and chronic
hepatitis, cirrhosis and tumors. The underlying causes of these disease
states include viral infections like hepatitis A, B and C alcohol, drugs,
metabolic disorders and immunological factors. Chronic liver disease
passes through a long period of minimal vague symptoms until the final
stages of jaundice and mental confusion appear.
Liver Dysfunction
This is different to liver disease in that the liver has not yet sustained
permanent or sufficient damage to cause gross impairment of its vital
functions. In those with a dysfunctional liver, the routine blood tests
of liver function are generally normal. A dysfunctional liver is not
working efficiently, and is overloaded, toxic or sluggish. Liver dysfunction
is much more common than liver disease, and may be a forerunner to liver
disease. In my experience of over 20 years of clinical medicine, I have
found that approximately one in every three persons has a dysfunctional
liver. Even if the level of dysfunction is only slight, it will still
have a negative impact on your immune system and energy levels.
Many people suffer with the symptoms and signs of a dysfunctional liver
for years, and yet the treating doctor or naturopath does not recognize
the significance of these symptoms. The result is that the symptoms
get treated while the underlying problem of an overloaded, toxic and
inefficient liver is ignored or only partially treated. Inevitably,
the patient’s symptoms deteriorate, and increasing doses of drugs such
as antibiotics, anti-inflammatory medication, immune-suppressants, pain
killers, cholesterol lowering drugs etc, are needed.
The full range of symptoms indicative of “dysfunctional liver syndrome”
can only be defined after a study of Eastern and Western medical disciplines.
Chinese doctors have long considered the liver to be the most important
organ in the body and indeed they call the liver, the “General of the
Army” of the body. I consider the liver to be the most strategic organ
in the body, because by improving its function we are able to help many
other body systems.
Symptoms associated with Liver Dysfunction
Abnormal Metabolism of Fats
Abnormalities in the level of fats in the blood stream, for example,
elevated LDL cholesterol and reduced HDL cholesterol and elevated triglycerides.
Arteries blocked with fat, leading to high blood pressure, heart attacks
and strokes. Build up of fat in other body organs (fatty degeneration
of organs). Lumps of fat in the skin (lipomas and other fatty tumours).
Excessive weight gain, which may lead to obesity. Inability to lose
weight even while dieting. Sluggish metabolism. Protuberant abdomen
(pot belly). Cellulite. Fatty liver. Roll of fat around the upper abdomen
- (liver roll).
Digestive Problems
Indigestion. Reflux. Haemorrhoids. Gall stones and gall bladder disease.
Intolerance to fatty foods. Intolerance to alcohol. Nausea and vomiting
attacks. Abdominal bloating. Constipation. Irritable bowel syndrome.
Pain over the liver - (upper right corner of abdomen & lower right
rib cage).
Blood Sugar Problems
Craving for sugar. Hypoglycaemia and unstable blood sugar levels. Mature
onset diabetes (TypeII) is common in those with a fatty liver.
Nervous System
Depression. Mood changes such as anger and irritability. Metaphysically
the liver is known as the “seat of anger”. Poor concentration and “foggy
brain”. Overheating of the body, especially the face and torso. Recurrent
headaches (including migraine) associated with nausea.
Immune Dysfunction
Allergies - sinus, hay fever, asthma, dermatitis, hives, etc. Multiple
food and chemical sensitivities. Skin rashes and inflammations. Increased
risk of autoimmune diseases.
Chronic Fatigue Syndrome. Fibromyalgia. Increase in recurrent viral,
bacterial and parasitic infections.
External Signs
Coated tongue. Bad breath. Skin rashes. Itchy skin (pruritus). Excessive
sweating. Offensive body odour Dark circles under the eyes. Yellow discolouration
of the eyes. Red swollen itchy eyes (allergic eyes). Acne rosacea -
(red pimples around the nose, cheeks and chin). Brownish spots and blemishes
on the skin (liver spots). Red palms and soles which may also be itchy
and inflamed. Flushed facial appearance or excessive facial blood vessels
(capillaries/ veins).
Hormonal Imbalance
Intolerance to hormone replacement therapy or the contraceptive pill
(eg. side effects).
Menopausal symptoms such as hot flushes may be more severe. Premenstrual
syndrome may be more severe.
NOTE:
All of the above symptoms are common manifestations of a dysfunctional
liver. However, they can also be due to other causes, of a more sinister
nature, so, in all cases of persistent symptoms it is vital to see your
doctor.
Liver Test
The purpose of this page is to assist people to understand the reasons
for the tests that are generally performed and make some sense of the
results. It is not intended to encourage “self diagnosis” A reliable
diagnosis of a liver condition can only be made by a qualified medical
practitioner after many factors have been investigated and ruled out.
This will involve taking a full medical history and more than likely
more tests will need to be performed. Therefore if it is always recommended
to see your physician if you suspect you have a liver problem.
What causes the enzymes to be raised in a Liver Function Test?
The reason why all or some of these enzymes become elevated in cases
of liver disease is that they are normally contained inside the liver
cells (hepatocytes). They only leak into the blood stream when the liver
cells are damaged. Thus measuring liver enzymes is only able to detect
liver damage and does not measure liver function in a sensitive way.
"The Healthy Liver and Bowel Book" Dr Sandra Cabot p 98
Other tests can be done to check the ability of the liver to manufacture
its vital proteins. These are tests for the proteins albumin, prothrombin,
and various globulins and they show characteristic abnormalities in
those whose liver function is abnormal. This may sound rather technical,
however your doctor can easily do all these tests from two or three
small vials of collected blood. In the early stages of liver disease
there may be no dramatic symptoms and thus you and your doctor may be
totally unaware that there is an underlying problem. Often the early
stages of liver disease are found coincidentally on a routine blood
test that includes tests for liver function.
Tests For Liver Function
What is a Liver Function Test?
Blood samples are analyzed for levels of specific enzymes in the blood
stream – there are generally 5 – 6 specific things that are checked.
Collectively these tests are called a “Liver Function Test” or LFT.
These enzymes are what are referred to as ‘markers’ of disease and dysfunction.
This is not to be confused with a 'Functional Detoxification Profile"
which tests the function of the detoxification pathways
How reliable is this test?
The name “Liver Function Test” is actually quite misleading as this
test does not actually measure the ‘function’ of the liver. It is more
a marker of the status of the integrity of the liver cell membranes.
Most of the standard or routine blood tests that your doctor will order
to check “liver function” are in reality only able to detect liver disease.
These tests are not sensitive enough to accurately reflect liver function.
It is possible to still have liver disease even though blood tests
are normal. Therefore the LFT alone is not capable of making a proper
diagnosis of many liver conditions. No test is completely accurate as
it is only an indication of what is happening at the time the test was
taken. It is therefore common practice to perform the test again on
another occasion, especially if any results are abnormal.
This is why it is important for you to consult a specialist in liver
diseases (hepatologist), if you suspect that your liver is unhealthy
and yet conventional blood tests remain normal.
Different diseases of the liver will cause differing types of damage
and affect liver function tests accordingly. It can be possible to give
an idea of which disease may be suspected from a liver function test,
but these tests are not the absolute way of diagnosing liver disease.
They are helpful, but not the whole story. They are also useful for
monitoring someone with liver disease, but are not always accurate.
As the LFT is really only showing the level of enzymes present in the
blood stream it is only showing that some damaging is occurring but
does not give an indication of the extent. This is where other tests
are required to give a more accurate picture of the extent of the damage
after the fact that damage is occurring has been established.
What is checked in a Liver Function Test?
A routine blood test for liver function will be processed by an automated
multichannel analyzer, and will check the blood levels of the following
:-
A Typical Liver Function Test
| Result Unit Reference |
• AP (Alk Phos) U/L (30 to 120)
• GGT (Gamma GT) U/L (5 to 35)
• LD Lactate Dehydrogenase U/L (100-225)
• AST (Aspartate aminotransferase) U/L (5 to 45)
• ALT (Alanine aminotransferase) U/L (5 to 45)
• Albumin g/L (38-55)
• Clotting Studies (Prothrombin Time) Seconds (11 to 13.5)
• Total Bilirubin - Normal range is 3 - 18 umol/L (0.174 - 1.04mg/dL). |
After the result is the laboratories reference range and the units
in which the result is expressed eg: U.L
Each laboratory will provide a “reference range” or ‘normal values’
This is the average reading that is deemed a ‘normal’ reading for the
majority of the population. This will assist the Doctor in determining
if the patients results are abnormal.
The normal values for liver function tests will vary between men and
women, at different times of the day and will change as you get older.
Different laboratories may have slightly differing reference ranges.
Liver Enzymes
• ALT - (alanine aminotransferase) - was previously called SGPT
is more specific for liver damage. The ALT is an enzyme that is produced
in the liver cells (hepatocytes) therefore it is more specific for liver
disease than some of the other enzymes . It is generally increased in
situations where there is damage to the liver cell membranes. All types
of liver inflammation can cause raised ALT. Liver inflammation can be
caused by fatty infiltration (see fatty liver) some drugs/medications,
alcohol, liver and bile duct disease.
• AST - (aspartate aminotransferase) which was previously called
SGOT. This is a mitochondrial enzyme that is also present in heart,
muscle, kidney and brain therefore it is less specific for liver disease.
In many cases of liver inflammation, the ALT and AST activities are
elevated roughly in a 1:1 ratio.
• AP - (alkaline phosphatase) is elevated in many types of liver
disease but also in non-liver related diseases. Alkaline phosphatase
is an enzyme, or more precisely a family of related enzymes, that is
produced in the bile ducts and sinusoidal membranes of the liver but
is also present in many other tissues. An elevation in the level of
serum alkaline phosphatase is raised in bile duct blockage from any
cause. Therefore raised AP in isolation will generally lead a physician
to further investigate this area. Conditions such as Primary Biliary
Cirrhosis and Sclerosing Cholangitis will generally show a raised AP.
Raised levels may also occur in cirrhosis and liver cancer. Alkaline
phosphatase is also produced in bone and blood activity can also be
increased in some bone disorders.
• GT - (gamma glutamyl transpeptidase) is often elevated in
those who use alcohol or other liver toxic substances to excess. An
enzyme produced in many tissues as well as the liver. Like alkaline
phosphatase, it may be elevated in the serum of patients with bile duct
diseases. Elevations in serum GGT, especially along with elevations
in alkaline phosphatase, suggest bile duct disease. Measurement of GGT
is an extremely sensitive test, however, and it may be elevated in virtually
any liver disease and even sometimes in normal individuals. GGT is also
induced by many drugs, including alcohol, therefore often when the AP
is normal a raised GGT can often (but not always) indicate alcohol use.
Raised GGT can often be seen in cases of fatty liver and also where
the patient consumes large amounts of Aspartame (artificial Sweetener)
in diet drinks for example.
• Bilirubin is the major breakdown product that results from
the destruction of old red blood cells (as well as some other sources).
It is removed from the blood by the liver, chemically modified by a
process call conjugation, secreted into the bile, passed into the intestine
and to some extent reabsorbed from the intestine. It is basically the
pigment that gives faeces its brown colour. Bilirubin concentrations
are elevated in the blood either by increased production, decreased
uptake by the liver, decreased conjugation, decreased secretion from
the liver or blockage of the bile ducts. In cases of increased production,
decreased liver uptake or decreased conjugation, the unconjugated or
so-called indirect bilirubin will be primarily elevated. In cases of
decreased secretion from the liver or bile duct obstruction, the conjugated
or so-called direct bilirubin will be primarily elevated.
Many different liver diseases, as well as conditions other than liver
diseases (e. g. increased production by enhanced red blood cell destruction),
can cause the serum bilirubin concentration to be elevated. Most adult
acquired liver diseases cause impairment in bilirubin secretion from
liver cells that cause the direct bilirubin to be elevated in the blood.
In chronic, acquired liver diseases, the serum bilirubin concentration
is usually normal until a significant amount of liver damage has occurred
and cirrhosis is present. In acute liver disease, the bilirubin is usually
increased relative to the severity of the acute process. In bile duct
obstruction, or diseases of the bile ducts such as primary biliary cirrhosis
or sclerosing cholangitis, the alkaline phosphatase and GGT activities
are often elevated along with the direct bilirubin concentration. (See
Gilberts Syndrome)
• Albumin - Albumin is the major protein that circulates
in the bloodstream. As it is made by the liver and secreted into the
blood it is a sensitive marker and a valuable guide to the severity
of liver disease. Low serum albumin concentrations indicate the liver
is not synthesizing the protein and is therefore not functioning properly.
The serum albumin concentration is usually normal in chronic liver diseases
until cirrhosis and significant liver damage is present. There are many
other proteins synthesized by the liver however the Albumin is easily,
reliably and inexpensively measured.
• Platelet count - Platelets are cells that form the primary
mechanism in blood clots. They're also the smallest of blood cells.
They derived from the bone marrow from the larger cells known as megakaryocytes.
Individuals with liver disease develop a large spleen. As this process
occurs platelets are trapped with in the sinusoids (small pathways within
the spleen) of the spleen. While the trapping of platelets is a normal
function for the spleen, in liver disease it becomes exaggerated because
of the enlarged spleen (splenomegaly). Subsequently, the platelet count
may become diminished.
• Prothrombin time (Clotting Studies) The prothrombin time is
tested to evaluate disorders of blood clotting, usually bleeding. It
is a broad screening test for many types of bleeding disorders. When
the liver is damaged it may fail to produce blood clotting factors.
How do the liver cell membranes get damaged in the first place?
Inflammation is a common cause of damage to the delicate liver cell
membranes. Liver inflammation is medically termed Hepatitis (hepato
= liver, itis = inflammation). This has many different causes including
long term alcohol excess, some medications such as long term antibiotics,
cholesterol lowering medications and pain killers, oral synthetic Hormone
Replacement, viral infections of the liver such as Hepatitis A, B &
C, auto-immune hepatitis, hemachromatosis, primary biliary cirrhosis,
exposure to toxic chemicals such as insecticides & pesticides &
organic solvents & incorrect diet.
Fatty liver can cause raised Liver Function Test results
One of the most common causes of liver inflammation is fatty liver
(see Fatty Liver) Fatty liver is also known as NASH, which stands for
Non- Alcoholic Steatorrhoeic Hepatosis. It is very common in overweight
persons, over the age of 30 who have had a long term poor diet high
in processed foods, sugar, saturated fat and dairy products.
Generally an ultrasound of the abdominal area should also be performed.
Many cases of fatty liver can be picked up this way. The ultrasound
will detect areas ‘of increased echogenicity’ meaning that the liver
tissue is beginning to become infused with fat.
What can be done to lower the readings?
In my medical practice where I do a lot of routine blood tests for
hormone levels and liver function in overweight patients, I often find
slight elevations in liver enzymes which signifies mild impairment of
liver function and slight liver damage. This can easily be reversed
with the Liver Cleansing Diet principles and specific dietary supplements
I have found that it is very difficult for many of my overweight patients
to lose weight even though they may be eating only normal amounts, unless
I first improve their liver function. Once they are five to six weeks
into the "Liver Cleansing Diet" their liver-function tests
are usually back to normal and the process of weight loss takes on increased
momentum. Yes, the liver is the strategic organ for those who have found
it very difficult to lose weight or simply just to maintain a healthy
weight as they get older. “The Liver Cleansing Diet” Dr Sandra Cabot
p 20.
TESTS FOR LIVER DISEASE
If you suspect that your liver is not working properly or may be diseased
ask your doctor to check your liver. The liver can be seen with various
imaging techniques, such as ultrasound scanning or CAT scanning, which
are done by a radiologist. An ultrasound scan of the upper abdomen will
show the size and shape of the liver, gallbladder, spleen, and pancreas.
CAT scanning is used to check for cancer or tumors of the liver.
Blood tests can check levels of serum bilirubin and bile acids, which
may be elevated in certain types of liver and gallbladder disease. If
the bilirubin is too high you may also notice that your bowel actions
are very pale and that your urine is a darker color because bilirubin
is diverted from the bowels to the urine.
When diagnosing liver disease, often, but not always the most used
test in each disease is generally:
| Disease
Test or Procedure |
| Fatty liver (NonAlcoholic Steatohepatitis or NASH) |
• Ultrasound
• Liver Biopsy |
| Hepatitis A |
• Antibody Test (Blood Sample) |
| Hepatitis B |
• Antibody & AntigenTests Hepatitis B DNA (Blood Sample)
• [Liver Biopsy if chronic to assess level of liver damage] |
| Hepatitis C |
• Antibody Test/ Hepatitis C RNA (Blood Sample)
• [Liver Biopsy if chronic to assess level of liver damage] |
| Primary Biliary Cirrhosis |
• Biopsy/ Bile duct imaging |
| Primary Sclerosing Cholangitis |
• Biopsy/ Bile duct imaging |
| Autoimmune Hepatitis |
• Liver Biopsy |
| Wilson’s Disease |
• Genetic Analysis/ Copper studies (Blood and Urine Samples) |
| Alcohol Related Liver Disease |
• Liver Biopsy/ Liver Function Tests |
What is a Biopsy?
This procedure involves using a special needle to remove tissue from
the liver to be examined in the laboratory. This will be used to assess
the extent of scarring, fatty infiltration or liver damage.
For the biopsy, you will lie on a hospital bed on your back or turned
slightly to the left side, with your right hand above your head. After
marking the outline of your liver and injecting a local anesthetic to
numb the area, the physician will make a small incision in your right
side near your rib cage, then insert the biopsy needle and retrieve
a sample of liver tissue. In some cases, the physician may use an ultrasound
image of the liver to help guide the needle to a specific spot.
How accurate is this test?
It is still regarded as the most accurate way of assessing the status
of the extent of damage to the liver. You will need to hold very still
so that the physician does not nick the lung or gallbladder, which are
close to the liver. The physician will ask you to hold your breath for
5 to 10 seconds while he or she puts the needle in your liver. You may
feel a dull pain. The entire procedure takes about 20 minutes.
Liver biopsy is considered minor surgery and is done at the hospital.
However it should be noted that this procedure is not without risk –
it is important that it is carried out by a very experienced Doctor.
The risks include puncture of the lung or gallbladder, infection, bleeding,
and pain. The bleeding in particular is a dangerous complication. It
carries about a 1/10000 death rate – some Doctors say its even higher.
Who should NOT have this procedure done?
• People with blood clotting disorders
• People who are on blood thinning medication such as Warfarin, Coumadins,
Ibuprofen, aspirin
• People with hemangiomas (benign liver cyst consisting of twisted congested
blood vessels)
What is an ultrasound or sonograph?
This is a non invasive method of assessing liver health. It is an imaging
procedure of the internal organs of the abdomen, including the liver,
gallbladder, spleen, pancreas and kidneys. The ultrasound machine sends
out high-frequency sound waves, which reflect off body structures to
create a picture. There is no ionizing radiation exposure with this
test. There are many reasons for performing an abdominal ultrasound
including looking for a cause of pain, for stones in the gallbladder
or kidney, or for a cause for enlargement of an abdominal organ. The
reason for the examination will depend on your symptoms.
Functional Tests of the Liver
Recently tests that assess the liver’s function, especially its detoxification
abilities, have become available. These tests are called "Functional
Liver Challenge Tests" or a "Functional Liver Detoxification
Profile". During these tests the liver is challenged with caffeine,
aspirin and paracetamol in safe oral doses. Samples of urine and saliva
are then collected at timed intervals and sent to the laboratory where
their levels of the excreted forms of these drugs are measured. These
tests are non-invasive and assess the ability of the liver to detoxify
and eliminate drugs and other chemicals. These tests are unique in that
they assess the functional capacity of the liver in both phase one and
phase two detoxification pathways. They can be conducted in the patient’s
home and are simple to perform. Your health care practitioner can arrange
them for you.
Functional Liver Detoxification Profile (FLDP)
• This is a non-invasive challenge test to assess the efficiency of
the liver to detoxify and eliminate toxic chemicals. Assessing multiple
path-ways with challenge substances provides clinical information about
individuals with imbalanced detoxification.
• Assess cumulative liver function impairment.
• Evaluate risk of free radical damage due to impaired liver function.
• Provide information on the liver's ability to process toxic loads.
• Monitor effectiveness of detoxification programs.
| The Functional Liver Detoxification
Profile provides valuable information for patients with: |
• Altered Intestinal Permeability
• Autoimmune Disease
• Chronic Fatigue Syndrome
• Encephalopathy
• Food Allergies
• Headaches
• Hepatitis
• Infectious Bowel Disease
• Intestinal Toxaemia
• Chemical Sensitivities
• Pre-Menstrual Tension
• Exposure to Xenobiotics |
Test Principle
Low doses of Caffeine, Aspirin and Paracetamol are taken orally. Saliva
and urine samples are collected at timed intervals and sent to the laboratory
for analysis.
Test Procedure
CAFFEINE / ASPIRIN / PARACETAMOL An average dose of 200mg of caffeine
(equivalent to two cups of strong coffee) is taken in the morning and
its clearance rate (Phase I) is determined by analyzing two saliva samples
taken at prescribed time intervals after ingestion. Aspirin (650mg)
and paracetamol (acetaminophen) (750mg) are taken before going to bed
and urine is collected over the following 10 hours. The total volume
of urine is noted and a sub sample taken off for analysis.
| Please NOTE: |
• Standard liver enzyme tests (LFTs) only assess existing pathological
damage to hepatocytes.
• Administration of therapeutic substances MUST be carried out under
the supervision of a medical practitioner.
• It is important that you read instructions accompanying the special
test kit received from the analytical laboratory and the advice/warning
information thoroughly before proceeding with the test.
• Ensure that you have NOT taken Aspirin or Paracetamol within 48
hours of commencing the test.
• The test is best performed over a 24 hour period.
• Advise your Practitioner if you suffer from asthma/ hay fever.
• Application of this test to children between the ages of 2-12
MUST be conducted under the supervision of a medical practitioner.
Separate test kits are available for adults and children.
General Information
• The test samples can be easily collected in the patient's home.
• Specially prepared specimen collection kits are available from
the recommended laboratories listed.
• Full test details and collection instructions are included in
the test kits. |

ADVICE: The individual doses of Caffeine, Aspirin and
Paracetamol used in this test are lower than the general ADULT therapeutic
course doses prescribes by Medical Practitioners (ie the test calls
for one dose whereas a course dose requires multiple doses at regular
time intervals). The use of these drugs, however, may be contraindicated
in young children, pregnancy, concurrent use of other drugs and in certain
clinical conditions. Please read the following warnings and refer to
your Medical Practitioner if in doubt.
WARNINGS:
CAFFEINE
Test Dose: 100-300 mg depending on body weight.
If your body weight is:
less than 80lbs/36kg then take 1 tablet
from 80lbs/36kg to 130lbs/59kg then take 2 tablets
over 130lbs/59kg then take 3 tablets
NOTE: Each tablet contains 100 mg caffeine which is the equivalent of
one cup of coffee.
Contraindications: None reported.
Adverse Reactions: Although uncommon, some people may experience heightened
nervousness, irritability, sleeplessness and occasionally rapid heart
beat.
ASPIRIN
Test Dose: 750 mg
Contraindications: Bleeding disorders, severe hepatic disease, kidney
disease, uraemia, erosive gastritis, peptic ulcer, asthma, hypersensitivity
to aspirin and other salicylates; patients taking anticoagulant therapy;
concurrent use of alcohol.
Adverse Reactions: Gastro-intestinal disburbances such as nausea, dyspepsia
(same for single dose)
PARACETAMOL
Test Dose: 750 mg
Contraindications: None reported.
Adverse Reactions: While reports of adverse reactions are rare, mild
effects such as dyspepsia, nausea, allergenic and hematological reactions
have been reported. However a causal relationship to the administration
of paracetamol has neither been confirmed or refuted.
DIETARY RESTRICTIONS
The following dietary restrictions must be observed for the Functional
Liver Detoxification Profile. DO NOT consume the following foodstuffs
before or during the test: Coffee, tea, cocoa, chocolate, cola soft
drinks; Medication containing caffeine or salicylates; Fruit, stoned
fruits, dried fruits (eg. sultanas, currants, raisins etc); Liquorice,
aniseed, peppermint (eg. sweets, lollies, gums etc); Spices (eg. curry,
dill, oregano, paprika etc). These foods contain many of the substates
for which the liver is being tested. to keep the test controlled and
make the results meaningful - outside sources of the chemicals must
not be consumed.
Functional Liver Detoxification Profile - FLDP, Interpretive Guide
Phase I - P450 Detoxification
Low caffeine clearance (Phase I) Indicates slow P-450 enzyme activity
and metabolic detoxification difficulty due to enzyme inhibitors e.g.
drugs, toxic metals, enterotoxins, liver damage, and/or insufficient
nutrient co-factors. May also reflect use of medications such as amphetamines,
cimetidine, and oral contraceptives.
High caffeine clearance (Phase I) Reflects excessive P-450 enzyme induction,
possibly due to exposure to cigarette smoking, alcohol, drugs (prescribed
and illicit), and absorption of enterotoxins (i.e. leaky gut). Also
implies greater production of free radicals therefore can indicate an
increased risk of free radical damage.
Low Sulphate/Creatinine Ratio Reflects: Low amount of glutathione and
sulphate available for detoxification.
Excess exposure to xenobiotics. Increased free radical activity. Molybdenum
deficiency (required for conversion of sulphites to sulphates). High
Sulphate/Creatinine Ratio A high sulphate/creatinine ratio suggests
adequate levels of glutathione and efficient sulphation conjugation.
Phase II - Conjugation Pathways
Low Glutathionation: indicates low levels of glutathione available
for removal of toxic intermediate metabolites and increased risk of
free radical activity.
Low Sulphation: inadequate sulphate reserves for conjugation of bio-transformed
molecules especially steroid hormones, drugs, xenobiotics and phenolic
compounds.
Low Glucuronidation: may also indicate low sulphation or glycination.
Glucuronidation is an important pathway when sulphation and/or glycination
are compromised.
Low Glycination: limited glycine available for salicylate conjugation.
Increased risk of free radical activity.
A High Phase II Result: Indicates increased burden for specific conjugation
pathways. Prolonged stress on a particular pathway will cause an increase
in free radical damage which, in turn, will reduce liver function in
the long term.
Low acetaminophen mercapturate, salicyluric acid, acetaminophen sulfate
or acetaminophen glucuronide (Phase II): Indicate inadequate Phase II
conjugation reactions. Low levels may reflect depletion of the particular
amino acids or nutrient cofactors used in the reactions, or diminished
enzymatic capacity for conjugation.
Elevated Phase I/Phase II ratios: May reflect elevated (induced) Phase
I processes or diminished Phase II conjugation reactions. The ratio
of Phase I to Phase II detoxification processes is important in determining
the toxicity of certain drugs, and these ratios may be significant indicators
of the balance of biological processes.
