From the book, Why Do I Still Have Thyroid Symptoms When My
Lab Tests Are Normal ?
By Dr. Datis Kharrazia
Although the book is written with emphasis on thyroid
auto-immune issues, this book is a most excellent introduction to the immune
system and auto-immunity. Nothing that I
quote here, however, can do the complex systems involved justice because these
are just bits and pieces of bigger picture that really needs to be understood
in its entirety in order to to understand how these bits and pieces fit into
it. I highly advise anyone with thyroid
issues, with immune system issues or needs, or who is facing auto-immune issues
get and read this book. It is in our
library system, however, it is one of those books that you may find yourself
really wanting to underline and highlight because there is just so much in this
book. Anyways, enough said...
Notes From The Book On Supporting/Building One’s Immune
System:
Dr. Kharrazian likens the function of the immune system to
the metaphor of a burglar breaking into your house.
1. The first aspect
of one’s immune system are the barriers (walls of the house): namely your skin
and the lining of your intestines, lungs, and brain…and he mentions holes in
the barriers.
2. When these have
holes in them, what gets in (the burglar) are “antigens” and “haptens."
3. The first
responders on the scene (security guards with no guns) are the “macrophages,”
Greek for “big eater,” are stationed in body tissue always on the lookout for
intruders. The macrophages envelope the
invader creating an “Antigen Presenting Cell” or “APC” that acts like a burglar
alarm.
4. The first
responders to the call for help are “T-Helper Cells” who organize the
attack. The T-helper cells send
messengers to bring the elite police force the “Natural Killer Cells” and
“Cytotoxic T-Cells” to swarm the intruder and destroy it.
5. Back at the police
station (sergeants), “T-Regulatory Cells” monitor the scene to ensure there are
enough T-helper cells and “T-Suppressor Cells” which stop the immune reaction
once the intruder is disarmed.
6. Since the immune
system wants to take no chances of a second attack, it assumes that every
burglar is a member of organized crime.
T-helper cells also fetch the detectives, “B-Cell Antibodies,” which
attach to the intruder and put all its information in a memory bank which will
allow the natural killer cells and cytotoxic T-cells to become increasingly
efficient at destroying the burglar if it ever comes around again.
A breakdown can happen in any of these areas, or combination
areas, of the immune system. Since each
aspect of our immune system requires different support, it is therefore vital
to first figure out where the breakdown is occurring.
Some of the possible scenarios are:
1. Some people do not
make enough T-suppressor cells so the immune system’s attack goes on and on and
innocent bystanders can often be mistaken for the enemy.
2. Some people make
too much “Interleukin 2” or “IL-2,” which is a chemical messenger that deploys
the natural killer cells and cytotoxic T-cells.
When these are in over abundance, like in the first scenario, innocent
tissue is at risk.
3. Some people make
too much “Interleukin 4” or “IL-4,” a chemical messenger that deploys
B-cells. An overabundance of B-cells
just looking for intruders may mistakenly tag innocent bystanders.
Then there are other causes of immune system breakdowns,
such as:
1. People eating high
carbohydrate diets which affects blood sugar, causing insulin surges that
stimulate overproduction of B-cells.
2. A parasitic
infection and/or multiple food intolerances drive up IL-4, causing an
overproduction of B-cells.
3. A chronic viral
infection drives up IL-2 causing an overproduction of natural killer cells and
cytotoxic T-cells.
So it could be systemic, or idiopathic, meaning for some
unknown reason the body is doing this, or it could be driven by something we
ourselves are doing…or, not-doing, as the case may be. So, to ask the question, is it an actual
auto-immune disease or is it something that we are doing causing something that
looks like an auto-immune disease?
Auto-immune is “not based on the tissue being attacked, but
on how the immune system is behaving.”
“It is not always possible to pinpoint what exactly triggers
a person’s genes to turn on an auto-immune disease.” And…“Once the gene for auto-immune disease
has been turned on, it cannot be turned off.”
“The trick,” he says, “is to discover which side of your
immune system is more active – the side that deploys natural killer cells and
cytotoxic T-cells, or the side that deploys B-cell antibodies.” If you are “producing too many natural killer
cells and cytotoxic T-cells […] then you are TH-1 dominant.” If you are “producing too many B-cells […] you are TH-2 dominant.”
TH = T-Helper Cells
Cytokines are like hormones – they are
chemical messengers that make things happen.
You “determine whether someone is TH-1 or TH-2 dominant by
measuring cytokines.”
“Also, it is important to note that not all auto-immune
diseases can be traced to a TH-1 or TH-2 dominance; other possible causes
include immune defects and deficiencies.
In other words, no cookbook recipes exist for managing an auto-immune
disease. Instead, a basic understanding
of immunology is key.”
The TH-1 Cytokines include:
- IL-2
- IL-12
- TNFa (tumor necrosis factor alpha)
- Interferon
The TH-2 Cytokines include:
- IL-4
- IL-13
- IL-10
“When addressing auto-immune disease, the goal is to restore
balance to the immune system.”
Beyond all the various things he addresses in his patients,
he states:
STEP ONE: SUPPORT THE
T-REGULATORY CELLS
- Emulsified Vitamin D (cholecalciferol). Emulsification is important so that someone
with poor digestion can absorb the nutrient.
It also prevents toxicity at higher doses. He does not recommend Cod Liver Oil,
stating: “Cod liver oil, although high
in vitamin D and possessing necessary cofactors for its absorption, does not
provide enough of the vitamin to modulate an auto-immune disease.” He also states, “The EPA and DHA in fish oil
also supports the T-regulatory cells.
(Taken in large amounts, cod liver oil delivers too much EPA and DHA,
which has blood thinning properties).”
He goes on to state, “Vitamin D supplementation is important for another
reason: Studies have shown that more
than 90 percent of people with autoimmune thyroid disease have a genetic defect
affecting their ability to process vitamin D.
Therefore, they need higher amounts of vitamin D to maintain
health. This can be the case even if a
blood test shows sufficient vitamin D: The defect is at the cellular receptor
site, so not enough vitamin D can gain entry into the cells.”
- Glutathione Cream.
“Glutathione works best when delivered intravenously or absorbed through
the skin.”
STEP TWO: BALANCE THE
TH-1 AND TH-2
“I do this by stimulating the side of the immune system that
is not dominant.”
Compounds That Stimulate TH-1
(NOTE: “These dampen a TH-2 dominance and will worsen the
auto-immune condition of a TH-1 dominant person.”):
- Astragalus
- Echinacea
- Beta-Glucan Mushroom
- Glycyrrhiza (from licorice)
- Melissa Officinalis (Lemon Balm)
Compounds That Stimulate TH-2
(NOTE: “These dampen a TH-1 dominance and will worsen the
auto-immune condition of a TH-2 dominant person.”):
- Caffine
- Green Tea Extract
- Grape Seed Extract
- Pine Bark Extract
- White Willow
Bark
- Lycopene
- Resveratrol
- Pycnogenol
Compounds That Modulate BOTH TH-1 and TH-2
- Probiotics
- Vitamin A
- Vitamin E
- Colostrum
Compounds That Dampen IL-1 Activating BOTH TH-1 and TH-2
- Boswellia
- Pancreatic Enzymes
- Tumeric (Curcumin)
“I always use immunological lab tests to determine whether a
person is TH-1 or TH-2 dominant so that I know how to properly tame and support
her overactive and poorly regulated immune system.”
^ I think this is important, and am a bit irritated that a
number of things on his lists are regular parts of Lyme protocols (hence, why I
cannot express deeply enough the importance of first understanding the
biological pathways you are working with)…and this is also, no doubt, a big
part of the answer why some protocols work for some and not others. It also suggests a good argument for
antibiotic-only treatments because in cases of auto-immune issues it is not
tripping any of the triggers (or not in the same way).
He goes on to say, “How do I know if the protocol for immune
modulation is working? Monitoring
symptoms is important of course, but I also use blood tests to monitor
cytokines and T and B cell populations along the way, too. They should begin to reach normal levels and
antibody test should become negative.
That doesn’t mean that the condition is cured, but it is dormant.”
“NOTE: A challenge test should only be done under the
supervision of a licensed health care professional. Also, some people develop auto-immune
reactions to brain and nerve tissue […]. It is important to NOT use this
protocol when destruction of nerve or brain tissue is at risk.”
“Quite often I will find that a specific antigen – a food,
mold, bacteria, chronic virus, or parasite – is provoking the autoimmune attack.”
“People can also develop an immune response to haptens,
which are environmental chemicals or heavy metals that provoke an immune
response. It is important to note that
not everyone will develop an autoimmune response to antigens or hapten. For instance, we all have varying degrees of
heavy metal toxicity, but not everyone’s immune system will mount an attack
against mercury, lead, cadmium, or other metals.”
Antigen = organic compoundsHapten = inorganic compounds
^ He tends to use “antigen” to refer to both.
“When an antigen is to blame for stimulating an autoimmune
attack, an immune panel of tests may show both the TH-1 and TH-2 cytokine are
high and T-suppressor cells are low.
This indicates that the body is currently in a heated battle against
something the immune system recognizes as an enemy.”
“Another essential immune panel measures the ratio of
T-helper cells to T-suppressor cells.
This is the CD4/CD8 test (CD4 measures T-helper cells and CD8 measures
T-suppressor cells).”
“Another clue that a hapten may be responsible for driving
an autoimmune disease is when a person’s response to both TH-1 and TH-2
stimulators makes them feel worse.”
Restoring the Immune Barriers
"Sometimes the active antigen infection can be due to a
heavy metal such as mercury. Although
most people have some degree of mercury in their bodies, not everyone’s immune
system will respond as if it is an infectious agent. If mercury or other environmental compounds
are creating an autoimmune response, this can be verified by antibody tests
against that particular compound. If the test comes back positive, removing the
compound is one way to address Hashimoto’s.
A recent study, for instance, looked at the impact of dental amalgams on
Hashimoto’s disease in people having an immune response to mercury. The researchers concluded that the removal of
mercury-containing dental amalgams contributed to the successful management of those
with the thyroid disorder.”
^ I think it is important to note, that there is a simple
test to see if your mercury fillings are affecting you. If they are, then that would be your answer
on removing them…and if not, it is unlikely that they are having anything to do
with why you are not improving. It is
important, I think, to note the pathway of things like mercury. When the body has too much it stores it
safely away in the body so that it can no longer hurt you. Some people feel that they need to go to
great lengths to try to get the stored toxins out of the body, but doing so can
do more harm than good. Anyways, he goes
on to state:
“In other cases, however, liberating stored mercury with
methods like chelation can exacerbate an autoimmune response. A good example involves autism. Many doctors peg autism on heavy metal
toxicity and prescribe chelation. I, on
the other hand, think that an immune response to mercury can trigger an
autoimmune attack on nerve or brain tissue, causing autism. Chelation releases stored mercury into the
system and can exacerbate an autoimmune autistic condition, causing more tissue
death and a worsening of symptoms.”
Later on he says, “It is better to live in peace with mercury than
permanently destroy brain tissue in an attempt to eliminate it.”
