Eclampsia in the Real Organism: A Paradigm of General Distress Applicable in Infants, Adults, Etc.
</h1>
<article class="posted">
<p>
To prevent the appropriation and abuse of our language by academic and professional cliques, I like to
recall my grandparents' speech. When my grandmother spoke of eclampsia, the word was still normal
English, that reflected the Greek root meaning, "shining out," referring to the visual effects that are
often prodromal to seizures. The word was most often used in relation to pregnancy, but it could also be
applied to similar seizures in young children. The word is the sort that might have been coined by a
person who had experienced the condition, but the experience of seeing hallucinatory lights is seldom
mentioned in the professional discussion of "eclampsia and preeclampsia."
</p>
<p>
Metaphoric thinking--using comparisons, models, or examples--is our natural way of gaining new
understanding. Ordinary language, and culture, grow when insightful comparisons are generally adopted,
extending the meaning of old categories. Although the free growth of insight and understanding might be
the basic law of language and culture, we have no institutions that are amenable to that principle of
free development of understanding. Institutions devoted to power and control are naturally hostile to
the free development of ideas.
</p>
<p>
Among physicians, toxemia (meaning poisons in the blood) has been used synonymously with preeclampsia,
to refer to the syndrome in pregnant women of high blood pressure, albumin in the urine, and edema,
sometimes ending in convulsions. Eclampsia is reserved for the convulsions themselves, and is restricted
to the convulsions which follow preeclampsia, when there is "no other reason" for the seizure such as
"epilepsy" or cerebral hemorrhage. Sometimes it is momentarily convenient to use medical terms, but we
should never forget the quantity of outrageous ignorance that is attached to so many technical words
when they suggest the identity of unlike things, and when they partition and isolate things which have
meaning only as part of a process. Misleading terminology has certainly played an important role in
retarding the understanding of the problems of pregnancy.
</p>
<p>
In 1974, when I decided to write Nutrition for Women, I was motivated by the awful treatment I saw women
receiving, especially during pregnancy, from physicians and dietitians. Despite the research of people
like the Shutes and the Biskinds, there were still "educated" and influential people who said that the
mother's diet had no influence on the baby. (That strange attitude affects many aspects of behavior and
opinion.)
</p>
<p>
How can people believe that the mother's diet has no effect on the baby's health? Textbooks used to talk
about the "insulated" fetus, which would get sufficient nutrients from the mother's body even if she
were starving. To "prove" the doctrine, it was pointed out that the fetus gets enough iron to make blood
even when the mother is anemic. In the last few years, the recognition that smoking, drinking, and using
other drugs can harm the baby has helped to break down the doctrine of "insulation," but there is still
not a medical culture in which the effects of diet on the physiology of pregnancy are appreciated. This
is because of a mistaken idea about the nature of the organism and its development. "Genes make the
organism," according to this doctrine, and if there are congenital defects in the baby, the genes are
responsible. A simple sort of causality flows from the genes to the finished organism, according to that
idea. <strong>It was taught that if "the genes" are really bad, the defective baby can make the mother
sick, and she contributed to the baby's bad genes.</strong> The idea isn't completely illogical, but
it isn't based on reality, and it is demonstrably false. (Race, age and parity have no effect on
incidence of cerebral palsy<strong>;</strong> low birth weight and complications of pregnancy are
associated with it<strong>: </strong>J. F. Eastman, "Obstetrical background of 753 cases of cerebral
palsy," Obstet. Gynecol. Surv. 17, 459-497, 1962.)
</p>
<p>
Although Sigmund Freud sensibly argued in 1897 that it was more reasonable to think that an infant's
cerebral palsy was caused by the same factors that caused the mother's sickness, than to think that the
baby's cerebral palsy <em>caused</em> maternal sickness and premature labor, <strong>more than 50 years
later people were still taking seriously the idea that cerebral palsy might cause maternal
complications and prematurity.</strong> (A.M. Lilienfield and E. Parkhurst, "A study of the
association of factors of pregnancy and parturition with the development of cerebral palsy," <em>Am. J.
Hyg. 53,</em> 262-282, 1951.)
</p>
<p>
Medical textbooks and articles still commonly list the conditions that are associated with
eclampsia<strong>: </strong> Very young and very old mothers, a first pregnancy or a great number of
previous pregnancies, diabetes, twins, obesity, excessive weight gain, and kidney disease. Some authors,
observing the high incidence of eclampsia in the deep South, among Blacks and on American Indian
reservations, have suggested that it is a genetic disease because it "runs in families." If poverty and
malnutrition are also seen to "run in families," some of these authors have argued that the bad genes
which cause birth defects also cause eclampsia and poverty. (L. C. Chesley, et al., "The familial factor
in toxemia of pregnancy," Obstet. Gynec. 32, 303-311, 1968, reported that women whose mothers suffered
eclampsia during their gestation were likely to have eclampsia themselves. Some "researchers" have
concluded that eclampsia is good, because many of the babies die, eliminating the "genes" for eclampsia
and poverty.)<strong>*</strong> Any sensible farmer knows that pregnant animals must have good food if
they are to successfully bear healthy young, but of course those farmers don't have a sophisticated
knowledge of genetics.
</p>
<p>
The inclusion of obesity and "excessive weight gain" among the conditions associated with eclampsia has
distracted most physicians from the fact that malnutrition is the basic cause of eclampsia. The
pathologist who, knowing nothing about a woman's diet, writes in his autopsy report that the subject is
"a well nourished" pregnant woman, reflects a medical culture which chooses to reduce "nutritional
adequacy" to a matter of gross body weight. The attempt to restrict weight gain in pregnancy has
expanded the problem of eclampsia beyond its association with poverty, into the more affluent classes.
</p>
<p>
Freud wasn't the first physician who grasped the idea that the baby's health depends on the mother's,
and that her health depends on good nutrition. Between 1834 and 1843, John C. W. Lever, M.D., discovered
that 9 out of 10 eclamptic women had protein in their urine. He described an eclamptic woman who bore a
premature, low-weight baby, as having "...been living in a state of most abject penury for two or three
months, subsisting for days on a single meal of bread and tea. Her face and body were covered with
cachectic sores." ("Cases of puerperal convulsions," <em>Guy's Hospital Reports, Volume 1, series 2,</em
> 495-517, 1843.) S. S. Rosenstein observed that eclampsia was preceded by changes in the serum (<em
>Traite Pratique des Maladies des Reins,</em> Paris, 1874). L. A. A. Charpentier specifically documented
low serum albumin as a cause of eclampsia (<em>A Practical Treatise on Obstetrics, Volume 2,</em>
William Wood &amp; Co., 1887). Robert Ross, M.D., documented the role of malnutrition as the cause of
proteinuria and eclampsia (<em>Southern Medical Journal 28,</em> 120, 1935).
</p>
<p>
In outline, we can visualize a chain of causality beginning with a diet deficient in protein, impairing
liver function, producing inability to store glycogen, to inactivate estrogen and insulin, and to
activate thyroid. Low protein and high estrogen cause increased tendency of the blood to clot. High
estrogen destroys the liver's ability to produce albumin (G. Belasco and G. Braverman, <em>Control of
Messenger RNA Stability,</em> Academic Press, 1994). Low thyroid causes sodium to be lost. The loss
of sodium albuminate causes tissue edema, while the blood volume is decreased. Decreased blood volume
and hemoconcentration (red cells form a larger fraction of the blood) impair the circulation. Blood
pressure increases. Blood sugar becomes unstable, cortisol rises, increasing the likelihood of premature
labor. High estrogen, hypoglycemia, viscous blood, increased tendency of the blood to clot cause
seizures. Women who die from eclampsia often have extensive intravascular clotting, and sometimes the
brain and liver show evidence of earlier damage, probably from clots that have been cleared. (Sometimes
prolonged clotting consumes fibrinogen, causing inability to clot, and a tendency to hemorrhage.) <em>M.
M. Singh, "Carbohydrate metabolism in pre-eclampsia," Br. J. Obstet. Gynaecol. 83, 124-131. 1976.

</p>
<p>
But the simple chain of causality has many lines of feedback, exacerbating the problem, and the
nutritional problem is usually worse than a simple protein deficiency. B vitamin deficiencies alone are
enough to cause the liver's underactivity, and to cause estrogen dominance, and a simple vitamin A
deficiency causes an inability to use protein efficiently or to make progesterone, and in itself mimics
some of the effects of estrogen.
</p>
<p>
Anything that causes a thyroid deficiency will make the problem worse. Thyroid therapy alone has had
spectacular success in treating and preventing eclampsia. (H. O. Nicholson, 1904, cited in Dieckman's
<em>Toxemias of Pregnancy,</em> 1952; 1929, Barczi, of Budapest; Broda Barnes, who prescribed thyroid as
needed, delivered more than 2,000 babies and never had a case of pre-eclampsia, though statistically 100
would have been expected.)
</p>
<p>
The clotting which sometimes kills women, can, if it is not so extensive, cause spotty brain damage,
similar to that seen in "multiple sclerosis," or it can occur in the liver, or other organ, or in the
placenta, or in the fetus, especially in its brain and liver. Some cases of supposed "post-partum
psychosis" have been the result of multiple strokes. When large clots occur in the liver or placenta,
the fibrinogen which has been providing the fibrin for disseminated intravascular coagulation can appear
to be consumed faster than it is produced by the liver. I think its disappearance may sometimes be the
result of the liver's diminished blood supply, rather than the "consumption" which is the way this
situation is usually explained. It is at this point that hemorrhages, rather than clots, become the
problem. The undernourished liver can produce seizures in a variety of ways--clots, hemorrhages,
hypoglycemia, and brain edema, for example, so eclampsia needn't be so carefully discriminated from "the
other causes of seizures."
</p>
<p>
Because I had migraines as a child, I was interested in their cause. Eating certain foods, or skipping
meals, seemed to be involved, but I noticed that women often had migraines premenstrually. Epilepsy too,
I learned, often occurred premenstrually.
</p>
<p>
In my experience of migraine, nausea and pain followed the visual signs, which consisted of a variable
progression of blind spots and lights. When I eventually learned that I could stop the progression of
symptoms by quickly eating a quart of ice cream, I saw that my insight could be applied to other
situations in which similar visual events played a role, especially "eclampsia" and "epilepsy." For
example, a woman who was 6 months pregnant called me around 10 o'clock one morning, to say that she had
gone blind, and was alone in her country house. She said she had just eaten breakfast around 9 AM, and
wasn't hungry, but I knew that the 6 month fetus has a great need for glucose, so I urged her to eat
some fruit. She called me 15 minutes later to report that she had eaten a banana, and her vision had
returned.
</p>
<p>
Early in pregnancy, "morning sickness" is a common problem, and it is seldom thought to have anything to
do with eclampsia, because of the traditional medical idea that the fetus "causes" eclampsia, and in the
first couple of months of pregnancy the conceptus is very small. But salty carbohydrate (soda crackers,
typically) is the standard remedy for morning sickness. Some women have "morning sickness"
premenstrually, and it (like the nausea of migraine) is eased by salt and carbohydrate. X-ray studies
have demonstrated that there are spasms of the small intestine (near the bile duct) associated with
estrogen-induced nausea.
</p>
<p>
Hypoglycemia is just one of the problems that develops when the liver malfunctions, but it is so
important that orange juice or Coca Cola or ice cream can provide tremendous relief from symptoms.
Sodium (orange juice and Pepsi provide some) helps to absorb the sugar, and--more basically--is
essential for helping to restore the blood volume. Pepsi has been recommened by the World Health
Organization for the rehydration of babies with diarrhea, in whom hypovolemia (thickening of the blood
from loss of water) is also a problem.
</p>
<p>
The problem of refeeding starving people has many features in common with the problem of correcting the
liver malfunction and hormone imbalances which follow prolonged malnutrition of a milder sort. The use
of the highest quality protein (egg yolk or potato juice, or at least milk or meat) is important, but
the supplementation of thyroid containing T 3 is often necessary. Intravenous albumin, hypertonic
solutions of glucose and sodium, and magnesium in an effective form should be helpful (magnesium sulfate
injected intramuscularly is the traditional treatment for eclampsia, since it is quickly effective in
stopping convulsions). While the sodium helps to restore blood volume and to regulate glucose, under
some circumstances (high aldosterone) it helps to retain magnesium<strong>;</strong> aldosterone is not
necessarily high during eclampsia.. Triiodothyronine directly promotes cellular absorption of magnesium.
Hypertonic glucose with minerals is known to decrease the destruction of protein during stress<strong

Katherina Dalton observed that her patients who suffered from PMS (and were benefitted by progesterone
treatment) were likely to develop "toxemia" when they became pregnant, and to have problems at the time
of menopause. In these women, it is common for "menstruation" to continue on the normal cycle during the
first several months of pregnancy. This cyclic bleeding seems to represent times of an increased ratio
of estrogen to progesterone, and during such periods of cyclic bleeding the risk of miscarriage is high.
Researchers found that a single injection of progesterone could sometimes eliminate the signs of toxemia
for the remainder of the pregnancy. Katherina Dalton, who continued to give her patients progesterone
throughout pregnancy, later learned that the babies treated in this way were remarkably healthy and
bright, while the average baby delivered after a "toxemic" pregnancy has an IQ of only 85.
</p>
<p>
Marian Diamond's work with rats clearly showed that increased exposure to estrogen during pregnancy
reduced the size of the cerebral cortex and the animals' ability to learn, while progesterone increased
the brain size and intelligence. Zamenhof's studies suggested that these hormones probably have their
effects largely through their actions on glucose, though they also affect the availability of oxygen in
the same way, and have a variety of direct effects on brain cells that would operate toward the same
end.
</p>
<p>
If Katherina Dalton's patients' IQs averaged 130, instead of the expected 85, the potential social
effects of proper health care during pregnancy are enormous.
</p>
<p>
But there is evidence that healthy gestation affects more than just the IQ. Strength of character,
ability to reason abstractly, and the absence of physical defects, for example, are strongly associated
with weight at birth.
</p>
<p>
Government studies and Social Security statistics suggest the size of the problem. The National
Institute of Neurological Diseases and Stroke found that birth weight was directly related to IQ at age
four, and that up to half of all children who were underweight at birth have an IQ under 70.(Chase.)
According to standard definitions, about 8% of babies in the U.S. have low birth weight.
</p>
<p>
Among people receiving Social Security income because of disability that existed at the age of 18, 75%
were disabled before birth. In 94% of these cases, the abnormality was neurological. (HEW.)
</p>
<p>
A study of 8 to 10-year-old children found that abstract verbal reasoning and perceptual/motor
integration are more closely related to birth weight than they are to IQ. (Wiener.)
</p>
<p>
National nutritional data show that in the U.S. <strong>the development of at least a million babies a
year is "substantially compromised" by prenatal malnutrition.</strong> Miscarriages, which are also
causally related to poor nutrition, occur at a rate of a few hundred thousand per year. (Williams.)
</p>

When a muscle is fatigued, it swells, taking up sodium and water, and it is likely to become sore.
Energy depletion causes any cell to take up water and sodium, and to lose potassium. An abnormal excess
of potassium in the blood, especially when sodium is low, affects nerve, muscle, and secretory
cells<strong>;</strong> a high level of potassium can stop the heart, for example. Cellular energy can
be depleted by a combination of work, insufficient food or oxygen, or a deficiency of the hormones
needed for energy production. When the swelling happens suddenly, the movement of water and sodium from
the blood plasma into cells decreases the volume of blood, while the quantity of red cells remains the
same, making the blood more viscous.
</p>
<p>
During the night, as adrenalin, cortisol, and other stress hormones rise, our blood becomes more viscous
and clots more easily. In rats, it has been found that the concentration of serum proteins increases
significantly during the night, presumably because water is moving out of the circulatory system. Even
moderate stress causes some loss of water from the blood.
</p>
<p>
If a person is malnourished, a moderate stress can overcome the body's regulatory capacity. If tissue
damage is extreme, or blood loss is great, even a healthy person experiences hypovolemia and shock.
</p>
<p>
C.A. Crenshaw, who was a member of the trauma team at Parkland Hospital in Dallas that worked on Kennedy
and Oswald, had been involved in research with G. T. Shires on traumatic shock. In his words, "we made
medical history by discovering that death from hemorrhagic shock (blood loss) can be due primarily to
the body's adjunctive depletion of internal salt water into the cells." (Shires' work involved isotopes
of sodium to show that sodium seems to be taken up by cells during shock.)
</p>
<p>
According to Crenshaw, "Oswald did not die from damaged internal organs. He died from the chemical
imbalances of hemorrhagic shock. From the time he was shot<strong>...</strong>until the moment fluids
were introduced into the body<strong>...</strong>" [19 minutes] "there was very little blood circulating
in Oswald's body. As a result, he was not getting oxygen, and waste built up in his cells. Then, when
the fluids were started, the collection of waste from the cells was dumped into the bloodstream,
suddenly increasing the acid level, and delivering these impurities to his heart. When the contaminated
blood reached the heart, it went into arrest<strong>....</strong>" The "waste" he refers to includes
potassium and lactic acid. Crenshaw advocates the use of Ringer's lactate to replace some of the lost
fluid. Since the blood already contains a large amount of lactate because the body is unable to consume
it, this doesn't seem reasonable. I think a hypertonic version of Locke's solution, containing glucose
and sodium bicarbonate as well as sodium chloride, would be better, though I think the potassium should
be omitted too, and extra magnesium would seem desirable. Triiodothyronine, I suspect, would help
tremendously to deal with the problems of shock, causing potassium, magnesium, and phosphate to move
back into cells, and sodium to move out, helping to restore blood volume and reduce the wasteful
conversion of glucose to lactic acid..
</p>
<p>
Albumin has been used therapeutically in preeclampsia (Kelman), to restore blood volume. Synthetic
polymers with similar osmotic properties are sometimes used in shock, and might also be useful in
eclampsia, but simply eating extra protein quickly restores blood albumin. For example, in a group of
women who were in their seventh month of pregnancy, the normal women's serum osmotic pressure was 247
mm. of water, that of the women with nonconvulsive toxemia was 215 mm., and in the women with eclampsia,
the albumin and osmotic pressure were lowest, with a pressure of 175 mm. In the eighth month, the
toxemic women who ate 260 grams of protein daily had a 7% increase in osmotic pressure, and a group who
ate 20 grams had a decline of 9%.(Strauss) In a group of preeclamptics, plasma volume was 39% below that
of normal pregnant women.
</p>
<p>
If the physiology of shock has some relevance for eclampsia, so does the physiology of heart failure,
since Meerson has shown that it is a consequence of uncompensated stress. The failing heart shifts from
mainly glucose oxidation to the inefficient use of fatty acids, which are mobilized during stress, and
with its decreased energy supply, it is unable to beat efficiently, since it remains in a partly
contracted state. Estrogen (which is increased in men who have had heart attacks) is another factor
which decreases the heart's stroke volume, and estrogen is closely associated with the physiology of the
free unsaturated fatty acids. The partly contracted state of the heart is effectively a continuation of
the partly contracted state of the blood vessels that causes the hypertension, and reduced tissue
perfusion seen in shock and eclampsia. Since shock can be seen as a generalized inflammatory state, and
since aspirin has been helpful in protecting against heart disease, it's reasonable that aspirin has
been tried as a treatment in pre-eclampsia. It seems to protect the fetus against intrauterine growth
retardation, an effect that I think relates to aspirin's ability to protect in several ways against
excesses of uunsaturated fatty acids and of estrogen. But, since aspirin can interfere with blood
clotting, its use around the time of childbirth can be risky, and it is best to correct the problem
early enough that aspirin isn't needed.
</p>
<p>
Besides protein deficiency and other nutritional deficiencies, excess estrogen and low thyroid can also
limit the liver's ability to produce albumin. Hypovolemia reduces liver function, and (like hepatic
infarcts) will reduce its ability to maintain albumin production..
</p>
<p>
The studies which have found that hospitalized patients with the lowest albumin are the least likely to
survive suggest that the hypovolemia resulting from hepatic inefficiency is a problem of general
importance, and that it probably relates to the multiple organ failure which is an extremely common form
of death among hospitalized patients. A diet low in sodium and protein probably kills many more people
than has been documented. If old age is commonly a hypovolemic condition, then the common salt
restriction for old-age hypertension is just as irrational as is salt-restriction in pregnancy or in
shock. Thyroid (T 3), glucose, sodium, magnesium and protein should be considered in any state in which
weakened homeostatic control of the composition of plasma is evident.

<strong>*Note:</strong> Although Konrad Lorenz (who later received the Nobel Prize) was the architect of
the Nazi's policy of "racial hygiene" (extermination of those with unwanted physical, cultural, or
political traits which were supposedly determined by "genes") he took his ideas from the leading U.S.
geneticists, whose works were published in the main genetics journals. Following the Nazis' defeat, some
of these journals were renamed, and the materials on eugenics were often removed from libraries, so that
a new historical resume could be presented by the profession. <strong></strong>

modalities of prescription after the publication of the later trials]. Presse Medicale, 1996 Jan 6-13,
25(1):31-6. Aspirin, an inhibitor of cyclo-oxygenase, is prescribed in a number of conditions related to
abnormal production of prostaglandins including gravidic hypertension. Results of the most recent trials
demonstrate that in patients with a past history of pre-eclampsia or intra-uterine growth retardation, a
pathological Doppler examination of the uterus, a pathological angiotensin test or an antiphospholipid
syndrome, prescription of aspirin at the dose of 100 mg/day can prevent recurrence or development of
pre-eclampsia or intra-uterine growth retardation. Treatment should begin as soon as possible during
pregnancy, certainly before development of clinical manifestations. After history taking and
identification of possible contraindications, bleeding time (Ivy method) is recorded before and after
prescription and should be lower than 8 minutes. In case bleeding time exceeds 10 minutes 10 to 15 days
after initiating aspirin, doses may be reduced to 50 mg per day or even 50 mg every two or three days to
reach the target level. Treatment should generally be continued up to 36 weeks gestation.

alcohol-induced birth defects and prostaglandin E levels in mice. Teratology, v.44, n.5, (1991):
521-530. The purpose of the present study was threefold. The first purpose was to determine if aspirin
(ASA) decreases alcohol-induced birth defects in mice in a dose-dependent fashion. The second purpose
was to see if the antagonism of alcohol-induced birth defects afforded by ASA pretreatment was related
to dose-dependent decreases in prostaglandin E (PGE) levels in uterine/embryo tissue. The third purpose
was to determine if ASA pretreatment altered maternal blood alcohol level.” In experiments 1 and 2,
pregnant C57BL/6J mice were administered ASA (0, 18.75, 37.5, 75, 150, or 300 mg/kg) on gestation day
10. One hour following the subcutaneous injection of ASA, mice received alcohol (5.8 g/kg) or an
isocaloric sucrose solution intragastrically. In experiment 1 the incidence of birth defects was
assessed in fetuses delivered by caesarean section on gestation day 19. In experiment 2 uterine/embryo
tissue samples were collected on gestation day 10 1 hr following alcohol intubation for subsequent PGE
analysis. In experiment 3 blood samples were taken at five time points following alcohol intubation from
separate groups of alcohol-treated pregnant mice pretreated with 150 mg/kg ASA or vehicle The results
from the three experiments indicated that ASA dose-dependently reduced the frequency of alcohol-induced
birth defects in fetuses examined at gestation day 19, ASA decreased the levels of PGE in gestation day
10 uterine/embryo tissue in a similar dose-dependentfashion, and ASA pretreatment did not significantly
influence maternalblood alcohol levels. These results provide additional support for the hypothesis that
PGs may play an important role in mediating the teratogenic actions of alcohol.

thromboxane A2 production plays a central role in the pathogenesis of these disorders. Low-dose aspirin
appears to reverse the above functional balance resulting in increased prostacyclin to thromboxane
ratio. The efficacy and safety of low-dose aspirin in preventing preeclampsia and fetal growth
retardation were tested in several randomized and uncontrolled trials. The data in the literature
suggest that low-dose aspirin is effective in reducing preterm birth due to the above complications in
selected high-risk pregnant women.

effects of estrogen in the anterior pituitary gland of the rat. Journal of Endocrinology, v.121, n.3,
(1989): 513-520. Two inhibitors of prostaglandin synthesis, indomethacin and aspirin, blocked the
increase of oestrogen-binding sites in the nuclear subcellular fraction, an increase which occurs after
the administration of oestradiol.
