Pre-eclampsia, oxidative stress, and Celiac sprue

Pre-eclampsia is a serious complication of pregnancy which can become life threatening to the mother and baby. High blood pressure and severe swelling of the lower legs and face are symptoms of pre-eclampsia. If the condition worsens it is called eclampsia and seizures may be the life threatening risk. The swelling can become severe enough that toxin removal by the kidneys is reduced.

What causes pre-eclampsia is not yet well understood. Providing IV solutions of magnesium sulfate just prior to delivery helps reduce risk of seizures and usually delivery of the baby causes the rest of the symptoms to resolve. However people who’ve experienced IVs of magnesium sulfate shared with me that it feels like fire running through their veins. Background information — magnesium is an electrically active mineral that during normal health is kept in a very narrow range within the blood and is largely found within the interior of cells and within the bones. Calcium is also electrically active and it is in higher concentration within the blood than within the interior of cells.

Skipping ahead, oxidative stress prenatally has been shown to be involved in pre-eclampsia and it causes an increase in calcium flow in the placenta. [1]

While looking for more information about pre-eclampsia I found a Celiac Sprue forum [2] that included questions and comments about whether anyone else with celiac gluten intolerance had also experienced pre-eclampsia or HELLP complications of pregnancy and if so any ideas why they might co-occur. HELLP is a blood coagulation problem which I didn’t look into but Celiac sprue and pre-eclampsia may be likely to co-occur because both involve oxidative stress:

Hi, I’m a dietitian with an autoimmune condition and previous work experience with prenatal health. I’ve been researching why the advice I gave when I was working helped so many women at the time worked – but isn’t in the mainstream medical treatment yet. Increasing magnesium rich foods such as beans, nuts, and seeds helped women that had a history of preeclampsia or high blood pressure to have a normal pregnancy.

In a nut shell – oxidative stress causes the placenta to increase flow of calcium. Too much calcium can cause other cellular reactions and fluid changes. And oxidative stress can be caused by gluten exposure when there is an underlying celiac autoimmune condition or probably other autoimmune conditions.

Re Celiac Sprue and oxidative stress, “long chain omega 3 fatty acids, plant flavonoids and carotenoids” were suggested as antioxidants that may help reduce the “oxidative stress, gene expression & production of inflammatory mediators”:  Celiac disease, inflammation and oxidative damage: a nutrigenetic approach.   Carotenoids include beta-carotene from carrots. Orange, red and dark green fruits and vegetables are generally good sources of carotenoids and plant flavonoids are also found in a variety of colorful fruits and vegetables. Omega 3 fatty acids are found in fish oil supplements or salmon, tuna, sardines – limit as a mercury source however during pregnancy or child bearing years. Vegetarian sources of a precursor omega 3 fat include flax seed meal (ground is digestible, whole flax seeds aren’t really), walnuts, and hemp seed kernels.

Sesame seeds, or tahini, sesame paste, has been shown in sports research to help reduce oxidative stress. The trial subjects ate 2 tablespoons per day of the seeds. Effects of Sesame (Sesamum indicum L.) Supplementation on Creatine Kinase, Lactate Dehydrogenase, Oxidative Stress Markers, and Aerobic Capacity in Semi-Professional Soccer Players.

Dark chocolate has also been shown to be beneficial antioxidant source.

Best wishes to any Celiac sufferers – I avoid gluten due to intolerance, initially for fibromyalgia like symptoms, and later autoimmune thyroid  antibodies were found but not antibodies for Celiac Sprue.

One more link that didn’t make it into the comment, magnesium deficiency in combination with elevated calcium levels may be involved in increasing oxidative stress: Magnesium deficiency and oxidative stress: an update, 2016,  [3]

Who am I? What is my purpose? I am a sick person, with professional health experience, who reads and writes about sickness for my own health and for other sick people — they are the ones who realize just how valuable health is and who may appreciate information whether it has a large price tag & an expensive office — or is shared freely out of love and concern. Pain hurts.

One more link because they’re so informative, the inflammatory system seems to be connected to both pain receptors and other nerve receptors so inflammation, (which leads to oxidative stress) activates pain receptors (nociceptors) – /speculation/ which could be part of the reason fibromyalgia and other inflammatory conditions cause pain – they may simply be causing pain receptors to be over-active due to inflammation: Neurogenic Inflammation – The Peripheral Nervous System’s Role in Host Defense and Immunopathology [4]

The inflammatory process causes oxidative stress: Chronic inflammation and oxidative stress as a major cause of age-related diseases and cancer. [5]

Adequate oxygen intake and flow to all the cells throughout the body is also necessary to prevent oxidative stress. Obesity can make it more difficult for oxygenated blood to reach all cells. [6]

Moderate exercise and deep breathing relaxation exercises may be helpful for improving oxygen intake and blood flow.

A previous article I wrote regarding magnesium and pre-eclampsia also includes information from a research hypothesis suggesting that intrauterine pressure itself may also be a trigger for worsening pre-eclampsia symptoms. [7] Not included in the hypothesis was why — which is likely to be due to the fact that physical (osmotic) pressure can cause TRP ion channels to open. TRP channels are a large group of specialized proteins which control flow of minerals such as calcium into the interior of cells. TRP channels include the ones that were shown to be dysregulated by oxidative stess in the placenta which allowed an increase of calcium to enter, which is described in the research article: Reactive Oxygen Species Inhibit Polycystin-2 (TRPP2) Cation Channel Activity In Term Human Syncytiotrophoblast [1]

Magnesium might help protect against beta amyloid placques

Working on experimental medications for a prenatal population places the infants at risk in addition to the female patients. In my professional experience instructing clients about raw pumpkin seeds and the DASH diet frequently helped prevent preeclampsia or high blood pressure problems from reoccurring for patients with a history of having had the problem during a previous pregnancy. Pumpkin seed kernels are similar to sunflower seeds, both are good sources of magnesium and many other nutrients. The DASH diet promotes eating a serving of nuts, seeds or beans daily as a source of magnesium. DASH stands for Dietary Approaches to Stop Hypertension. [1]

Additional note: *Raw pumpkin seeds were my recommendation because the toasted salted ones can be very salty which would dilute the amount of magnesium naturally available in the seed compared to the large amount of sodium available from the added salt. Excess sodium can cause increased urinary losses of magnesium in the average person and may increase risk of high blood pressure in people who are salt sensitive. [5]

In a recent study conducted in 19 hypertensive patients after 2 months of adherence to a low (50 mmol/d) and high (200 mmol/d) sodium intake, the investigators observed an increase in intracellular (erythrocyte) calcium and sodium concentrations and a reduction in magnesium concentration during salt loading, primarily in salt-sensitive subjects.82 [5]

Nutritional strategies recommended to help prevent Alzheimer’s disease include increasing intake of magnesium. Research has found that low levels of magnesium promoted build up of  beta amyloid protein while high levels of magnesium promoted breakdown of the misshapen proteins.

“Lab studies show that magnesium modulates enzymes involved in amyloid beta production; at low levels, magnesium favors amyloid beta buildup, while at higher levels it favors amyloid beta breakdown.101,102″ [2]

That article also contains good news for coffee drinkers; drinking 3 to 5 cups of caffeinated coffee per day is associated with reduced risk for Alzheimer’s disease. The article suggests that the caffeine content itself seems to provide the protective effects. [2] Coffee is also a good source of magnesium, perhaps that is a coincidence. However three to five cups of coffee is more than is recommended during pregnancy; one cup per day is likely safe while six cups of coffee per day may be harmful for pregnancy. The article also recommends blueberries and curcumin (found in turmeric which is commonly used in mustard and in curry powder) which would be safe during pregnancy.

The misshapen proteins have a protective effect against bacteria and the yeast Candida albicans so a chronic lowgrade infection may be an underlying cause of the accumulation of beta amyloid placques. [3] [4]

Good news about the deficit and about preeclampsia

With so many sad stories in the news it was nice to read an opinion piece with a positive tone. The deficit may seem huge but  it was encouraging to read that in relation to the national Gross Domestic Product (GDP), the national deficit has stabilized over the last few years. [1]

More jobs leads to more income which allows more people to buy more products and services which leads to more jobs to create more products and services  — which increases the GDP.

There was also good news in the prenatal health industry – an inexpensive diagnostic test has been discovered that can detect preeclampsia during early stages of the prenatal condition. Misshapen proteins similar to those found in Alzheimer’s disease were found to be present in the urine of women with preeclampsia. The beta-amyloid proteins have an unusual folded shape which can’t be broken down by enzymes and instead collect in the placenta and disrupt blood flow to the growing infant. [2]

Discovery of an accurate and inexpensive diagnostic test may add to the GDP through direct sales of the paper-based Congo Red Dot urine test and by helping prevent sick days during pregnancy. Preeclampsia can be life threatening for the woman and child but more typically the condition is associated with high blood pressure and increased protein losses in the urine. It is a leading cause of premature delivery which increases risk of low birth weight and other birth defects. [3] The discovery of the presence of beta-amyloid proteins in preeclampsia may also help researchers identify possible causes the condition, which are not known at this time.

Following the clue about the special type of protein found in common between Alzheimer’s and preeclampsia led me to a third condition that is associated with both conditions and with amyloidosis, which is a non-specific term referring to an excess of the misshapen proteins.

Cardiomyopathy can be a diagnosis  or symptom found with Alzheimer’s, preeclampsia, amyloidosis and it also may be associated with hypo- or hyperthyroidism or with infectious conditions such as sarcoidosis. Cardiomyopathy may also occur with starvation and with deficiencies of potassium and magnesium or taurine, carnitine, selenium and thiamine (vit. B1). [4] The amino acid taurine has also been found useful for preventing damage associated with Alzheimer’s disease. [5]

Starvation is certainly bad for pregnancy and so are nutrient deficiencies but at least those problems have known solutions – increase intake of healthy foods. A prenatal person with severe nausea and vomiting might not easily be able to increase their intake but use of targeted supplements or nutrient dense foods might help reduce the severity of symptoms or prevent worsening of an underlying condition.

Detecting who is at risk for preeclampsia before symptoms are severe could provide time to test and treat autoimmune thyroid disease which may not have been detected by standard thyroid lab tests. If sarcoidosis were present then excessive use of vitamin D and calcium might increase risk of there being a deficiency of magnesium and potassium.

Babies are made from nutrients not from medications. So discovering a medication that helps break down beta-amyloid protein might be helpful but finding out why the body is producing the folded malfunctioning protein and how to stop their production would be more helpful.

Interesting news from the pet food industry – It may be better not to feed cats raw fish more than three times per week because some species, when fresh and unheated, may be a source of an enzyme, thiaminase, which can  cause excessive break down of the B vitamin thiamine. And taurine is frequently added to processed foods for pet cats because heat processing causes destruction of the essential amino acid. [6]

Pre-eclampsia, Magnesium Deficiency, or Grass Staggers?

Pre-eclampsia is a frequent and life threatening problem for pregnant and postpartum women that can occur prenatally or up to 48 hours after delivery. The primary cause of the syndrome has been unrecognized in the medical field. However, the treatment and prevention of magnesium deficiency has been well understood in the dairy industry and the symptoms of the two conditions are very similar.

We study animals in medical research because it is unethical to experiment on humans. Farmers and vets care for dairy animals because it is ethical and profitable to help maintain their health. What they learn can help us understand other mammals too – such as humans.

Hypomagnesemia, also known as grass staggers, can occur in the pregnant or postpartum cow, but it can also occur in herds feeding on low magnesium fields. Weakness and falls occur in the cattle and they recover when feed is provided that contains adequate magnesium. The best treatment is prevention by providing extra magnesium if the feed has low levels. [1]

Magnesium deficiency can cause leg cramps, constipation, weakness, falling, cardiac arrythmias, edema and hypertension, anemia and poor immune health, ringing in the ears, irritability and headaches, and when severe seizures are possible. [2] I have had some of these symptoms – including the “wobbles” – feeling weak in the legs and almost stumbling. These symptoms are quite similar to those described for pre-eclampsia and at its most severe seizures are also a risk.

Current care for a human with pre-eclampsia might involve calcium channel blocker pharmaceuticals prenatally for controlling hypertension and intravenous doses of magnesium sulfate in the ER or delivery room for preventing or treating eclamptic seizures. Calcium causes muscle fibers to contract and magnesium allows them to relax.

Calcium channel blockers are patent-able pharmaceuticals trying to perform the job nature assigned to magnesium. The movement of potassium and sodium through ion channels in nerve cell membranes is well understood. A similar interaction is known about calcium and magnesium in the contraction of muscle fibers. Magnesium is the main gate keeper inside of the cell; it can prevent entry of calcium. When low on magnesium the muscles may be flooded with calcium and the constant contraction of the muscle fibers can turn into early labor cramps and possibly seizures.

Puffy ankles (edema) means intracellular fluid is leaking out and more calcium channel blockers are necessary, but more magnesium please. The prenatal woman is low in magnesium because she has been using extra to grow a baby – she can’t grow a baby out of pharmaceuticals.

Eight percent of pregnancies may be affected by pre-eclampsia/eclampsia and the current medical recommendation suggests that calcium and aspirin might help. [4] A different source states that the condition is a problem for up to 10% of women in developing nations and affects between 3-5% of pregnancies for women in the USA. [9]  Pregnant people are already told to consume extra calcium in their diets. If that strategy were working then why do eight percent of pregnancies still have pre-eclampsia problems?

Magnesium supplements have been reported to be helpful for preventing leg cramps during pregnancy in one study but results from another study didn’t replicate the results. [5]  A large study has begun based in Brazil that plans to provide the trial group of prenatal participants with two 150 mg magnesium supplements per day throughout the pregnancy in the hopes of preventing pre-eclampsia and reducing the number of infants born prematurely or at a low birth weight. [10] Another study focused on assessing the difference in long term mineral status of patients who had pre-eclampsia prenatally compared to those who didn’t. The results found that long term calcium status was the same which does not support the current theory that calcium deficiency is involved in the condition. [11]

A different study focused on the difference in current trace mineral status between patients with pre-eclampsia and those without. Blood levels of copper, zinc, selenium, calcium and magnesium were measured. Copper was the only mineral found to have similar levels between the two groups. The blood level of the other four minerals was significantly lower in women who had pre-eclampsia then in the group without the condition during their pregnancy. [12]

When the body is too low in magnesium then the body will increase hormone levels that cause a drop in calcium levels. Too much calcium and too little magnesium in the blood can cause heart symptoms so there are several ways the body can prevent an imbalance between blood levels of calcium and magnesium. A study that looked at whether magnesium sensitive genes were involved in blood pressure control during pregnancy did find that one was more active in pregnancy compared the non-pregnant group.  The gene TRPM6 was more active in the pregnant group than in women in the control group. [13]

Other research regarding the condition has noted an increased risk among close family members (mothers, daughters, sisters – if one has pre-eclampsia, other close female relatives are statistically more likely to also experience it in their pregnancies.)

A study that measured the vitamin D, hormone D, parathyroid hormone, albumin, and calcium blood levels of postpartum women who had had pre-eclampsia and those wh0 hadn’t during their pregnancies and found no significant difference in any of the levels between the two groups. Both groups had low vitamin D levels but normal levels of hormone D, parathyroid hormone, albumin and calcium. [15]

A study at the University of Benin found a significant correlation between low magnesium and increased prevalence of pre-eclampsia. The study concludes with a clear recommendation that consuming magnesium rich foods during pregnancy may improve the outcome:

“Pre-eclampsia and pre-term birth are associated with hypomagnesemia in pregnancy; hence, magnesium supplementation or magnesium-rich diet consisting of green leafy vegetables, soy milk and legumes may improve outcome.  [14]

A review of research regarding magnesium and prenatal health also concluded with a recommendation for pregnant women to consume adequate magnesium rich foods:

This review provides recommendations for further study and improved testing using measurement of red cell magnesium. Pregnant women should be counseled to increase their intake of magnesium-rich foods such as nuts, seeds, beans, and leafy greens and/or to supplement with magnesium at a safe level. [16]

Magnesium sulfate is used during labor and delivery to help prevent seizures in women with pre-eclampsia/eclampsia. I was told that the large dose feels painfully like fire in the veins. Which makes sense because it is an electrically active ion typically found in large amounts only within cell fluid rather than also freely available within the blood plasma. Some clients were very motivated to eat better if it would help prevent blood pressure problems from reoccurring and reduce the possibility of IV magnesium from being necessary. Simple solutions like pumpkin seeds and the DASH diet may be safer too. The high dose of intravenous magnesium sulfate can lead to cardiac problems and patients who receive the treatment are carefully monitored which takes additional staff time and other medical resources. [6]

Ibuprofen or other non-steroidal anti-inflammatory drugs (NAISDs) may help protect the infant during pregnancy if an infection is also part of the problem underlying pre-eclampsia. The ibuprofen helps reduce an increase in cytokines. The cytokine flood is an inflammatory reaction that may be associated with an increased risk to the infant for mental health problems developing later in life. [7]

Pre-eclampsia can be prevented by eating more magnesium rich foods throughout pregnancy. Beans, nuts, seeds and dark green vegetables are rich in magnesium. Chocolate is a good source, and there is a little magnesium in most foods. Whole grains are also good sources except the phytate content reduces mineral absorption. Shelled pumpkin seed kernels are similar to sunflower seeds in texture but they are greenish in color. Both are good sources of magnesium and other nutrients. Pumpkin seeds are a good vegetarian source of zinc, an essential trace mineral.

Mom and baby need magnesium daily. Having a moderate calcium intake will actually help both nutrients to be more usable to the body, baby, and bones. Frequent use of carbonated drinks, coffee, black tea, and acidic juices can cause the kidneys to waste magnesium. A diet high in meats and dairy products is also acid producing during breakdown and bone stores of magnesium may be used during excretion of the waste products if magnesium isn’t available from the diet. Our kidneys actively save calcium while using magnesium to remove the excess acid or excess calcium. Use of calcium rich OTC drugs like Tums or Rolaids frequently may decrease magnesium.

The intestines may not be absorbing magnesium well. Calcium is rare in nature except in dairy products. Our bodies expect lots of magnesium and not much calcium from our day’s intake. Too much vitamin D, when active, can cause even more calcium absorption in the intestines.

Magnesium containing skin creams may reduce leg cramps and other prenatal discomforts. Epsom salt foot soaks or baths can be soothing and nourishing as well.

Herbal teas are very nourishing in general – a few would not be recommended with pregnancy but raspberry leaf tea has been used successfully for generations.

“Raspberry leaves as well as the fruit contain many valuable vitamins needed during pregnancy. As well as containing iron, they are rich in vitamins A, C, B, E, calcium, manganese and magnesium. Magnesium particularly contributes to the strengthening of the uterine muscles.” [18]

The DASH diet was designed for helping prevent or manage high blood pressure rather than for pregnancy but pre-eclampsia can involve high blood pressure and the diet includes more emphasis on magnesium rich foods than the standard diet plans. The DASH diet plan includes a group for beans/nuts/seeds which are all good sources of magnesium. [8]

A prenatal diet plan is primarily different from a standard woman’s diet plan by having one additional dairy serving for extra calcium and the equivalent of one additional mixed snack during the second and third trimesters. During the first trimester calorie needs are similar to standard. Make the additional mixed snack a magnesium rich snack and pre-eclampsia might not become a problem. Corn chips and bean dip, peanut butter toast, or pumpkin seed kernels in a trail mix would all be snacks containing magnesium and other nutrients.

Continuing a diet with more magnesium, zinc, selenium, and adequate calcium intake may also help protect women with a history of pre-eclampsia from experiencing heart disease symptoms later in life. An association has been observed in medical research between a history of having had pre-eclampsia and increased risk of heart disease. [17] The DASH diet was designed to help reduce cardiovascular risks associated with high blood pressure. Continuing to follow the diet plan may help protect against heart disease.

Differences in the TRPM6 gene may underlie both the risk for pre-eclampsia and for heart disease risk. In an animal based study providing adequate magnesium helped protect the animals with differences in the TRPM6 gene. [19] TRPM6 channels are more prevalent in epithelial cells (type of cell that forms the skin and the lining of the GI tract) while TRPM7 channels are common throughout the body. Both types transport magnesium. Evidence suggests the TRPM7 type are involved in hypertension. [20] TRPM7 channels may be more involved in risk of heart attack (myocardial ischemia). [21]

More information about TRP channels is included in this post about Irritable Bowel Syndrome: http://transcendingsquare.com/2016/03/30/and-what-do-osmomechanical-stress-changes-of-temperature-chili-powder-curry-powder-ginger-benicar-hormone-d-steroids-and-cannabinoids-have-in-common/

Which led me to wonder if there is any association between IBS and pre-eclampsia – one study found some co-occurrence that was not statistically significant. There was an increased risk (25-30%) found for miscarriage and having a diagnosis of IBS  and depression/anxiety prior to becoming pregnant (how severe the symptoms was not assessed). [22]

A hypothesis regarding intrauterine pressure and pre-eclampsia mentions that it is associated with cell stress and decreased magnesium levels were noted:

“Jarosz et al. reported that in lab animals exposed to IAH of 25 mmHg, histology of the brain demonstrated evidence of ischemic neuronal cell stress and decreased magnesium levels [73].” [23]

A brief background regarding TRP channels – they act as pressure release valves so that organs leak rather than overfill. As a visual picture think of blowing up a balloon, eventually you have to stop or it will pop. The TRP channels would allow the balloon to leak instead of popping. The channels are located throughout the body and are formed from a large protein or group of proteins that cross the cell membranes. Magnesium is an electrically active mineral that provides the energy required to keep the channels closed and only allow transport of desired chemicals through the channel.

Having too little magnesium available leaves the channels without energy to stay closed and prevent fluid or other chemicals from crossing through the channel. Depending on the difference in pressure fluid and chemicals might rush into the cell from the surrounding fluid (extracellular fluid) or fluid and chemicals might rush out of the cell (intracellular fluid) into the surrounding fluid.

The hypothesis about intrauterine pressure and pre-eclampsia includes background information on the condition but magnesium is only referenced (see the excerpt above), its role in TRP channels was not discussed.

Emergency guidance suggested having the woman experiencing severe symptoms physically get into a kneeling position or lay horizontally on their left side:

Within the limitations of this analysis, data suggest that IAP may be altered throughout pregnancy by modifying the maternal position (altering the force direction), with the lowest pressure values obtained in knee–chest and left lateral positions. The negative pressure values obtained in the knee–chest position are important, as inversion of the maternal abdomen may provide an easily available and effective emergency intervention for PE, should this hypothesis be confirmed.” [23]

The article doesn’t provide further description of the position. My guess is a position that was recommended at the time I was pregnant for helping prevent breech delivery – get on hands and knees and then lower the chest and head to the floor, and then relax and stay there a while, having a pillow and watching TV is okay. Yes, see here, scroll down the page: [24]
