- We are always subjected to antigenic burdens. The important question has to do with our ability to limit the
- inflammatory response to these burdens.
- </p>
- <p>
- In MS, it is clear that the inflammatory process itself is destructive, and that estrogen is a major
- predisposing factor. Unsaturated fatty acids, and dietary imbalance of amino acids interact closely with
- hyperestrogenism and hypothyroidism to produce the autoimmune degenerative diseases.
- </p>
- <p>
- Reduction of the mediators of inflammation is better than augmenting a single antiinflammatory agent such as
- cortisol. Although immunosuppressive drugs, including the "essential fatty acids," do alleviate inflammatory
- symptoms temporarily, they probably contribute to the underlying pathology.
- </p>
- <p>
- People with MS have chronically increased production of cortisol. This creates a distortion of protein
- assimilation, resembling a nutritional protein deficiency. Excessive serotonin and estrogen cause a
- relatively uncontrolled production of cortisol. A vicious circle of inflammatory mediators and amino acid
- imbalance can result.
- </p>
- <p>
- Depression, lupus, migraine, menopause, diabetes, and aging have several important metabolic features in
- common with MS.
- </p>
-
- <p>
- Popular therapies are illogical, and are likely to cause disease progression.
- </p>
- <p>
- High quality protein, thyroid, pregnenolone and progesterone tend to correct the underlying pathology. These
- are antiinflammatory, but they are not immunosuppressive or catabolic.
- </p>
- <p>
- High altitude and sunny climate are associated with a low incidence of MS.

- Multiple sclerosis (MS), like other autoimmune diseases, affects women more often than men (about 2 to 1),
- has its onset during the reproductive years (especially after the age of 30, when estrogen is very high), is
- often exacerbated premenstrually, and is sometimes alleviated by pregnancy (Drew and Chavez, 2000), when
- progesterone is very high. Women with a high ratio of estrogen to progesterone have been found to have the
- most active brain lesions (Bansil, et al., 1999). Most of the mediators of inflammation that are involved in
- MS--mast cells, nitric oxide (NO), serotonin, prolactin, lipid peroxidation, free fatty acids,
- prostaglandins and isoprostanes, and the various cytokines (IL, TNF)--are closely associated with estrogen's
- actions, and in animals, autoimmune diseases can be brought on by treatment with estrogen (Ahmed and Talal).
- </p>
-
- <p>
- The strong association of MS with estrogen has led to an illogical, but popular and well-publicized medical
- conclusion that estrogen is protective against MS, and some have claimed that estrogen has beneficial
- therapeutic effects. This strange way of thinking has its equivalent in the idea that, since women are much
- more likely than men to develop Alzheimer's disease, estrogen is protective against it; or that, since women
- have more fragile bones than men do, and their progressive bone loss occurs during the times of their
- greatest exposure to estrogen, estrogen prevents osteoporosis.
- </p>
- <p>
- In this medical environment, close associations between estrogen and degenerative diseases are acknowledged,
- but they are given a meaning contrary to common sense by saying that the association occurs because there
- isn't enough estrogen. The stove burns you because it isn't hot enough.
- </p>
- <p>
- As Dave Barry would say, I'm not making this up. Recently well publicized articles have suggested that
- estrogen protects the brain (even against stroke!) because it increases serotonin and NO. There is something
- almost esthetically pleasing when so many major errors are concentrated into a single article. Nitric oxide
- and serotonin are both neurotoxic (Joseph, et al., 1991; Skaper, et al., 1996; Parkinson, et al., 1997;
- Santiago, et al., 1998; Barger, et al., 2000), as a result of suppressing mitochondrial respiration. NO
- plays a major role in lipid peroxidation and demyelination. It's interesting to see serotonin and NO openly
- associated with estrogen, whose mitochondrial toxicity has been carefully hidden from public view.
- </p>
- <p>
- There are several theories about the cause of MS, old theories about genes and viruses, and newer theories
- about bacteria, vitamin deficiencies, oil deficiencies, poisons, and reactions to vaccinations (especially
- for hepatitis B and influenza). The only theory that has been abandoned is the 19th century psychiatric
- theory about "hysterical paralysis," though occasionally someone does still talk about emotional causes of
- multiple sclerosis; the term "female hysteria" has evolved into "conversion disorder."
- </p>
- <p>
- Each of the main theories has a few facts that seem to support it, but neglects to account for many other
- facts. Everyone agrees that the immune system is involved in MS in some way, but that's really where the
- problem starts, because of the idea that inflammation is an intrinsic part of immunity. If "inflammation is
- necessary and good," then it becomes a problem to define exactly where the boundary is between an
- appropriate reaction and a degenerative process. Edema, reduced cellular respiration, loss of normal
- functions, fibrosis in its various degrees, each component of inflammation can be seen in a good light, as
- part of a "defensive immune reaction." When tissue injury leads to repair, it "must" be seen as beneficial,
- even if it leads to the formation of a scar in place of functional tissue, because the comparison is between
- an imagined worst possible outcome, and an imperfect recovery, rather than comparing the inflammatory
- process with the possibility that a potentially noxious agent might have done no harm at all.
- </p>
- <p>
- The simplest illustration of how inflammation relates to the organism's resources was an experiment in which
- blood glucose was varied, while an animal was exposed to chemicals that varied from mildly irritating to
- potentially deadly. When the animal had very low blood sugar, the mildest irritant could be deadly, but when
- its blood glucose was kept very high, even the deadly antigens were only mildly irritating. Varying the
- blood sodium concentration had similar, but weaker, effects.
- </p>
- <p>
- There is a tendency to see inflammation not only as a normal part of immunity, but to see it as being
- proportional to the nature of the antigen, except when the immune system has been primed for it by previous
- contact, in which case the organism will either not react at all (because it has become immune), or it will
- react much more violently than it did on the first exposure, because it has become allergic. But, in
- reality, the mere concentration of glucose and sodium in the blood (and of thyroid, and many other
- substances that aren't considered to be part of the immune system) can make a tremendous difference in the
- degree of "immunological" reaction.
- </p>
- <p>
- In the excessively sensitive condition produced by hypoglycemia, several things happen that contribute to
- the maladaptive exaggerated inflammatory response.
- </p>
- <p>
- Adrenaline increases in hypoglycemia, and, if the adrenaline fails to convert glycogen into glucose, it will
- provide an alternative fuel by liberating free fatty acids from fat cells.
- </p>
-
- <p>
- If the liberated fatty acids are unsaturated, they will cause serotonin to be secreted, and both serotonin
- and the unsaturated fatty acids will suppress mitochondrial respiration, exacerbating the hypoglycemia. They
- will stimulate the release of cytokines, activating a variety of immunological and inflammatory processes,
- and they will cause blood vessels to become leaky, creating edema and starting the first stages of fibrosis.
- Both adrenaline and serotonin will stimulate the release of cortisol, which mobilizes amino acids from
- tissues such as the large skeletal muscles. Those muscles contain a large amount of cysteine and tryptophan,
- which, among other effects, suppress the thyroid. The increased tryptophan, especially in the presence of
- free fatty acids, is likely to be converted into additional serotonin, since fatty acids release tryptophan
- from albumin, increasing its entry into the brain. Free fatty acids and increased serotonin reduce metabolic
- efficiency (leading to insulin resistance, for example) and promote an inflammatory state.
- </p>
- <p>
- Fats in the blood-stream have easy access to the brain, and the unsaturated free fatty acids produce brain
- edema (Chan, et al., 1983, 1988). When brain edema is caused by vascular leakage, proteins that are normally
- excluded can enter. The stimulated, excited and fatigued brain exchanges glutamine for tryptophan,
- accelerating its uptake from the blood.
- </p>
- <p>
- When a tissue is injured or stressed, antibodies are formed in response to the altered components of that
- tissue. Therefore, we could call a bruise or a sprain an autoimmune condition, but there are no commercial
- tests for bruised-shin antibodies. The availability of tests for specific antibodies seems to be the
- essential factor in classifying a condition as autoimmune, as in "autoimmune thyroiditis." Unfortunately,
- this way of using language is nested in a culture that is full of unrealistic ideas of causality, and
- thousands of people build their careers on the search for the "mutated genes that are responsible for the
- disease," and for the drugs that will correct the defect.
- </p>
- <p>
- Early in the study of immunology, the focus was on antibodies. Even earlier, inflammation had been
- conceptualized in terms of the "humors," and other prescientific ideas. As soon as multiple
- sclerosis/hysterical paralysis was classified as an autoimmune disease, primitive ideas about the nature of
- the immune system, interacting with primitive ideas about the nature of the brain and the structure of
- cells, blended into the various theories of what the disease is.
- </p>
- <p>
- Rather than seeing immunological nerve damage as the cause of all the other features of multiple sclerosis,
- I think it's important to look at some of the general features of the condition, as contexts in which to
- interpret the events in the nerves.
- </p>
- <p>
- It has been known for a long time that the incidence of MS tends to increase with distance from the equator.
- Incidence is low in sunny dry climates, and at high altitudes. Two clear dietary influences have been found:
- eating pork, and horsemeat.
- </p>
- <p>
- People with MS don't regulate their body temperature very well. Their nerve conduction is slow, and in
- normal people, conduction is faster at higher temperatures, but in people with MS the conduction is slower
- at the normal temperature of 98.6O F than at lower temperatures. A subnormal temperature is also associated
- with old age, and with the hot flashes of menopause.
- </p>
- <p>
- Brain metabolism of glucose is very low in multiple sclerosis, and in my own observations, the general
- metabolic rate is subnormal. However, some people reason that the hypometabolism is caused by the lesions,
- rather than vice versa.
- </p>
-
- <p>
- Animals that lack the unsaturated fatty acids have a higher metabolic rate and ability to use glucose,
- converting it to CO2 more readily, have a greater resistance to toxins (Harris, et al., 1990; even cobra
- venom: Morganroth, et al., 1989), including endotoxin (Li, et al., 1990)--preventing excessive vascular
- leakage--and to immunological damage (Takahashi, et al., 1992), and to trauma, and their neuromuscular
- response is accelerated while fast twitch muscles are less easily fatigued (Ayre and Hulber, 1996).
- </p>
- <p>
- In people with MS, the blood is more viscous, and the platelets tend to clump together more easily. Their
- cortisol level is higher than normal, and their pituitary adrenal-cortex-stimulating hormone is harder to
- suppress. This is a condition that is also seen in depression and old age. Despite the chronically elevated
- cortisol, people with MS typically have hypoglycemia. They are occasionally found to have low blood sodium,
- hyponatremia, but this is hard to determine when the blood's water content is variable. Their prolactin is
- likely to be high, and this can result from high estrogen, high serotonin, low sodium, or low thyroid.
- Drinking too much water can increase prolactin, and can damage the nerves' myelin enclosures; too much
- serotonin tends to cause excessive drinking. Disturbances of blood glucose, sodium, and water content can
- disrupt the brain's myelin structure. High estrogen disturbs the blood osmotically, making it retain too
- much water in relation to the solutes, and this relates to many of estrogen's effects; since simple osmotic
- variations can damage the myelin structures, it seems that this mechanism should be investigated thoroughly
- before it is assumed that the immunological events are primary.
- </p>
- <p>
- Mast cells, which promote inflammation by releasing substances such as histamine and serotonin (and make
- blood vessels leaky), are more numerous in the brain in multiple sclerosis than in normal brains. Since
- platelet clumping releases serotonin, and also because serotonin excess is suggested by so many other
- features of MS, serotonin antagonists (ondansetron and ketanserin, for example) have been used
- therapeutically with success.
- </p>
- <p>
- Estrogen causes mast cells to release their inflammatory mediators, and it causes platelets to aggregate,
- releasing their serotonin. Since estrogen dominance is closely associated with the presence of active brain
- lesions, antiestrogen therapy would seem obvious in MS. Progesterone counteracts estrogen's effects on both
- mast cells and platelets.
- </p>
-
- <p>
- Aspirin protects against a variety of inflammatory processes, but it's most famous for the inhibition of
- prostaglandins. While aspirin is often used to relieve pain in MS, and another inhibitor of prostaglandin
- synthesis, indomethacin, has been used therapeutically in MS, it would seem appropriate to investigate more
- carefully aspirin's possible role in preventing or relieving MS.
- </p>
- <p>
- A simple protein deficiency has many surprising effects. It lowers body temperature, and suppresses the
- thyroid, but it increases inflammation and the tendency of blood to clot. Since the brain and heart and
- lungs require a continuous supply of essential amino acids if they are to continue functioning, in the
- absence of dietary protein, cortisol must be produced continuously to mobilize amino acids from the
- expendable tissues, which are mainly the skeletal muscles. These muscles have a high concentration of
- tryptophan and cysteine, which suppress the thyroid. Cysteine is excitoxic, and tryptophan is the precursor
- for serotonin. Presumably, their presence in, and stress-induced release from, the muscles is one of the
- mechanisms that reduce metabolic activity during certain types of stress.
- </p>
- <p>
- When pregnant animals are deprived of protein, the newborn animals have abnormally high levels of serotonin,
- and the enzymes responsible for that excess tend to maintain the serotonin excess even when they are grown
- and have adequate protein. This is analogous to the effect of excess estrogen early in life, which creates a
- tendency to develop breast or prostate cancer in adulthood. It would be interesting to study the gestational
- experience, e.g., length of gestation and birth weight, of the people who later develop MS.
- </p>
- <p>
- Although people in the northern countries aren't normally protein-starved, they do tend to get a large part
- of their protein from the muscle meats. In traditional cultures, all parts of the food animals were
- eaten--chicken feet, heads, and necks, animals' ears and eyeballs, etc.--and so the amino acid balance was
- favorable for maintaining a high metabolic rate and preventing stress.
- </p>
-
- <p>
- The observation that multiple sclerosis is associated with the consumption of pork and horsemeat, but not
- beef, lamb, or goat, is very interesting, since the fat of those animals is essentially like the fats of the
- plant materials that they eat, meaning that it is extremely high in linoleic and linolenic acids. The rumen
- of cows, sheep, and goats contains bacteria that convert the polyunsaturated fats into more saturated fats.
- Unsaturated fats inhibit the enzymes that digest protein, and MS patients have been reported to have poor
- digestion of meat (Gupta, et al., 1977).
- </p>
- <p>
- The polyunsaturated fats are in themselves toxic to mitochondria, and suppress glucose oxidation, and
- inhibit the thyroid function, with the same suppressive effect on the ability to oxidize glucose, but they
- are also turned, enzymically, into the prostaglandins, and non-enzymically, by spontaneous lipid
- peroxidation, into the toxic isoprostanes. The isoprostanes, and some of the prostaglandins, are elevated in
- the brain and other tissues of people with MS.
- </p>
- <p>
- Lipid peroxidation is very high in multiple sclerosis. Nitric oxide (whose synthesis is promoted by estrogen
- in most parts of the brain) is a free radical that activates peroxidation.
- </p>
- <p>
- Lipid peroxidation selectively destroys, naturally, the unstable polyunsaturated fats. In atherosclerosis,
- the blood vessel plaques contain very little unsaturated fat. This is because they are peroxidized so
- rapidly, but their high ratio of saturated to unsaturated fats has been used to argue that the
- polyunsaturated oils are "heart protective." Similar arguments are often made in MS, though some studies
- don't support the idea that there is a lack of any of the unsaturated fats. Since lipid peroxidation is very
- high, it would be reasonable to assume that there was an abundance of polyunsaturated fats being peroxidized
- through reactions with catalysts such as iron (S.M. LeVine, 1997) and nitric oxide and peroxynitrile.
- </p>
- <p>
- I believe that an important aspect of the intolerance for heat so often reported in people with MS could be
- the tendency of relative hyperthermia to release increased amounts of free fatty acids into the blood
- stream. Women, because of estrogen's effects, usually have much higher levels of free fatty acids in the
- blood than men do. Estrogen increases the release of free fatty acids from stored fat, and the unsaturated
- fats synergize with both estrogen and prolactin, increasing their effects.
- </p>
- <p>
- Temperature regulation apparently involves some nerve cells that sense temperature very accurately, and
- change their activity accordingly. Water has a remarkably high heat capacity, meaning that it takes a
- relatively large amount of heat to change its temperature. The "disappearing heat" is being consumed by
- structural changes in the water. Proteins have the same sort of structural complexity as water, and together
- they can make effective temperature transducers, "thermometers." (Other substances tend to undergo major
- structural changes only as they melt or vaporize. The famous "liquid crystals" have a few distinct
- structural phases, but cytoplasm is like a very subtle liquid crystal.) The "thermostat cells" are actually
- responding to a degree of internal structure, not to the temperature in the abstract. So things that change
- their internal structure will modify their temperature "set-point."
- </p>
-
- <p>
- Increased estrogen causes an animal to lower its temperature, and it probably does this by increasing the
- "structural temperature" of the thermostat cells, "melting" their internal structure. Progesterone causes
- the animal to increase its temperature, and it apparently does this by increasing the structure/decreasing
- the structural temperature of the thermostat cells. If you put ice in the thermostat, the room gets hot.
- </p>
- <p>
- A cell's internal structure is equivalent to its readiness to work. Fatigue represents a slightly "melted"
- state of the cell, in which structure appears to have been consumed along with the chemical energy reserves.
- Experiments that demonstrated this effect were very clear, but they were ignored because they didn't fit
- people's stereotyped idea of the cell. With a very sensitive thermometer, it's possible to measure the heat
- produced by a nerve when it is stimulated. That's not surprising. But it's surprising that, when the nerve
- is recovering from the stimulation, it absorbs heat from its environment, lowering the temperature locally.
- That even violated some people's conception of "entropy," but it can easily be demonstrated that changing
- the form of some materials changes their heat capacity, as when a rubber band is stretched (it gets hot), or
- contracts (it gets cooler).
- </p>
- <p>
- The excitants, estrogen and cortisol, slow the conduction of nerves, because they cause its internal
- structure to be dissipated. They create a "pre-fatigued" state in the cell.
- </p>
- <p>
- In experiments with rabbit hearts, Szent-Gyorgyi showed that estrogen decreased the heart's readiness to
- work, and that progesterone increased its readiness to work, and he said it did this by "building
- structure." He pointed out that, for a given drug or other stimulus, cells have a characteristic response,
- becoming either more activated or more inhibited, but he showed that, outside the normal concentration or
- intensity range of the stimulus, a cell's response is often reversed.
- </p>
- <p>
- If this is the situation in the nerves in MS, it explains the strange behavior, in which warming the nerve
- reduces its function. The implication is that internal structure (and energy) must be restored to the
- nerves. In experiments that I have described in previous newsletters, increasing sodium, ATP, carbon
- dioxide, and progesterone, and increasing the ratio of magnesium to calcium, have been found to increase
- cellular energy and structure. The thyroid hormone is ultimately responsible for maintaining cells' energy
- and structure, and responsiveness, but if it is increased suddenly without allowing all the other factors to
- adjust, it will raise the temperature too suddenly. It needn't take a long time, but all the factors have to
- be present at the same time.
- </p>
-
- <p>
- Serotonin, melatonin, estrogen, and polyunsaturated fats all tend to lower body temperature. Since estrogen
- and the unsaturated fats are cellular excitants, the actual decrease in body temperature helps to offset
- their excitatory effects.
- </p>
- <p>
- Both bright light and high altitude tend to reduce serotonin's effects. The tissue carbon dioxide retained
- at high altitude reduces the incidence of many diseases, and multiple sclerosis might be affected as heart
- disease and cancer are. It is known that carbon dioxide is involved in myelin's regulation of its own water
- content. Hyperventilation, by causing a loss of carbon dioxide, releases both histamine and serotonin,
- making blood more viscous, while making blood vessels more permeable, and causing them to constrict.
- </p>
- <p>
- If people with MS have developed it through the interactions of excessive estrogen, serotonin, unsaturated
- fats, iron, and water, and deficient thyroid, and deficient pregnenolone produced in the myelin-forming
- cells (oligodendrocytes), there are many things that can be done to stop its progress, and possibly to
- reverse it.
- </p>
- <p>
- Since a sudden increase in temperature will release increased amounts of the pro-inflammatory fats, things
- should be changed gradually. Increased salt is thermogenic, but increased magnesium is protective against
- hyperthermia, so increased magnesium (epsom salts baths, for example, coffee, fruits, some vegetables and
- meats) would be helpful. Magnesium is rapidly lost from cells in hypothyroidism. Sugar, when accompanied by
- fats and minerals, as in milk, is needed to lower cortisol, and to maintain thyroid activity. Balanced
- proteins, such as cheese, potatoes, eggs, and beef- or lamb-broth (for the gelatin and mineral content in
- particular) will prevent the tryptophan excess that suppresses the thyroid and is potentially a nerve toxin.
- Saturated fats, used regularly, reduce the immediate toxic antimetabolic effects of the stored unsaturated
- fats, but it takes a long time to change the balance of stored fats.
- </p>
- <p>
- Since aspirin lowers temperature, is antiinflammatory, in some situations antiestrogenic, and is a powerful
- antioxidant, it is likely that it would alleviate symptoms and prevent progression of MS, as it does in
- other degenerative diseases. Since platelet aggregation is likely to be involved in the focuses of
- inflammation, aspirin might help to prevent the formation of new areas of damage.
- </p>
-
- <p>
- While the glucocorticoids are useful for their antiinflammatory actions, cortisol is known to promote the
- killing of brain cells by excitotoxicity. Since estrogen decreases GABA, and both estrogen and serotonin
- activate the excitatory amino acid transmitters, the addition of synthetic glucocorticoids to the
- pre-existing cortisol excess is likely to damage parts of the brain in addition to the inflamed areas.
- </p>
- <p>
- The excess cortisol of depression, old age, and hyperestrogenism often comes down with use of a thyroid
- supplement, but pregnenolone has a very direct action (in opposition to serotonin) that can quiet the
- pituitary, reducing ACTH and cortisol. Progesterone has some similar effects, and is protective against
- excess cortisol, and is a major factor in nerve and brain restoration. Thyroid, progesterone, and
- pregnenolone are all involved in the formation of new myelin, and in the prevention of the edema that
- damages it.
- </p>
- <p>
- Since thyroid and progesterone decrease the formation of estrogen in inflamed tissue, while cortisol
- stimulates its formation, it would seem wise to use thyroid and progesterone for their immediate
- antiinflammatory effects, which include the inhibition of NO formation (Drew and Chavez, 2000), and their
- lack of the excitotoxic, estrogen-stimulating effects of the glucocorticoids. While the glucocorticoids are
- catabolic and liberate cysteine and tryptophan from muscles, thyroid and progesterone are not catabolic, and
- protect against the toxic consequences of those amino acids.

- functions in rats. Ayre KJ, Hulbert AJ The effects of manipulating dietary levels of essential
- polyunsaturated fatty acids on the function of isolated skeletal muscles in male Wistar rats were examined.
- Three isoenergetic diets were used: an essential fatty acid-deficient diet (EFAD), a diet high in essential
- (n-6) fatty acids [High (n-6)], and a diet enriched with essential (n-3) fatty acids [High (n-3)]. After 9
- wk, groups of rats on each test diet were fed a stock diet of laboratory chow for a further 6 wk. Muscle
- function was examined by using a battery of five tests for soleus (slow twitch) and extensor digitorum
- longus (EDL; fast twitch). Tests included single muscle twitches, sustained tetanic contractions,
- posttetanic potentiation, sustained high-frequency stimulation, and intermittent low-frequency stimulation.
- Results for muscles from the High (n-6) and High (n-3) groups were very similar. However, the EFAD diet
- resulted in significantly lower muscular tensions and reduced response times compared with the High (n-6)
- and High (n-3) diets. Peak twitch tension in soleus muscles was 16-21% less in the EFAD group than in the
- High (n-6) and High (n-3) groups, respectively [analysis of variance (ANOVA), P < 0.01). During
- high-frequency stimulation, EDL muscles from the EFAD rats fatigued 32% more quickly (ANOVA, P < 0.01)].
- Also, twitch contraction and half-relaxation times were significantly 5-7% reduced in the EFAD group (ANOVA,
- P < 0.01). During intermittent low-frequency stimulation, soleus muscles from the EFAD group generated
- 25-28% less tension than did the other groups (ANOVA, P < 0.01), but in EDL muscles from the EFAD group,
- endurance was 20% greater than in the High (n-6) group (ANOVA, P < 0.05). After 6 wk on the stock diet,
- there were no longer any differences between the dietary groups. Manipulation of dietary fatty acids results
- in significant, but reversible, effects in muscles of rats fed an EFAD diet.
