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]

GPI anchors are cell membrane glycoproteins

Glycosylphosphatidylinositol (GPI)-anchored proteins are long and firmly embed within the membrane and leave an extension out over the surface of the membrane. One end of the protein stays embedded firmly within the cell membrane and the other end can attach to a variety of important molecules such as enzymes and antigens. The enzyme or antigen is held above the cell membrane in a position that makes it available to be activated on the cell surface.

The phosphatidylinositol end is lipid (oil or fat) based and dissolves well in the fatty acid rich environment found within the membrane. The glyco- or sugar part of the molecule is able to dissolve in water or form bonds with other proteins or carbohydrates and is found on the end of the molecule that sticks out over the surface of the membrane.

GPI anchor proteins are essential for life. Mice that were experimentally made to lack the gene thought to encode for GPI anchor proteins did not survive. Experimental “knockout” mice are usually observed to see what types of function the knocked out gene might have performed. The experiment showed that GPI anchors were necessary for basic survival of baby mice. (Ref. 1, Brooks, Dwek, Schumacher, 2002, p 225) When a protein is found to be so essential that a “knockout” mouse doesn’t survive than more minor differences are attempted to be made in order to try to find out what types of functions are changed or are missing from the more slightly modified “knockout” mice.

Background information: GPI anchors are found in some types of G-protein couple receptors and may have importance within the cannabinoid receptor system which has been found to play early and essential roles in implantation of the newly fertilized egg within the mother’s uterus.

To termites, trees are like giant sugar cubes

Sugar cubes contain the disaccharide known as sucrose which is made up of one molecule of the monosaccharide most common in fruit called fructose in addition to one molecule of the monosaccharide called glucose which is essential for energy production within the body and brain.

The cellulose portion of trees is made of long fairly straight chains of glucose with no fructose, so trees and sugar cubes aren’t really alike. The bonds between table sugar and tree fiber are at slightly different angles which means a hungry person or animal would require different enzymes in order to be able to break them down during digestion into smaller molecules and atoms for further use as an energy source.

The straighter angle between the simple sugars of plant fiber allow the linked chains of glucose to line up with each other.  When lined up the fibers then can form layers, which might seem a little like sheets of paper stacked on top of each other in a book, except it would be a round cylinder doughnut shaped book. Cellulose is one type of plant fiber, it and other types of plant fiber are found in the cell walls throughout the plant in the leaves, stems and roots.

Chitin is similar strong chain of the simple sugar N-acetylglucosamine. The simple sugars in chitin and cellulose both have the slightly straighter beta angle than the bonds found in energy storage starches or polysaccharides. Termites [3] and the bacteria found in the stomach of grazing animals are able to digest the stronger beta bonds of cellulose.

Humans and most other animals can’t digest the strong beta bonds of cellulose because a specific enzyme is needed. The termites and bacteria in the stomach of grazing animals can make the enzyme from other chemicals but humans and the grazing animals themselves can’t make it.

Energy rich plant starches have alpha type bonds between the simple sugars. Alpha bonds connect at an angle that might twist into a spiral chain similar to the double helix spiral of DNA.

The angled alpha bonds are also found in branching shapes of storage starches like glycogen or amylose. The sugar molecule at the end of each ‘branch’ is available for rapid digestion. Glycogen is the energy storage polysaccharide of glucose in animals and humans and amylose is the form of glucose storage used in plants. Glycogen is slightly more branched than amylose.

Tree bark and tree sap both contain glucose but the bark contains cellulose and the sap would have amylose or a similar alpha bonded energy storage starch. A shiny insect shell or seashells also are a type of sugar but not glucose. Shells contain N-acetyl-glucosamine in the form of chitin.

Supplements of glucosamine may be helpful for reducing joint pain. Clinical research studies with patients have found 1500 mg/day may be beneficial. [2]

Increase in electromagnetic radiation may be associated with increased autism

A graph showing a similar rate of increase in electromagnetic radiation exposure and increased rates of autism can be seen around 42 minutes in the following video, Dr. Erica Mallery-Blythe – Electromagnetic Radiation, Health and Children 2014:

This type of radiation can be from wireless cell phones or laptops or from living very close, within a few miles, of high powered electric lines or power stations.

And even wirelessly connected toys might be harmful to children. [1, 2, 3] A computer or telephone that is not wireless, but is on an old-fashioned landline would not have the same level of electromagnetic radiation.

Tinfoil hats would only act as an antennae and possibly increase radiation absorption, however grounded metal foil might absorb the radiation rather than deflecting it and causing it simply to bounce around more. Water also absorbs this type of radiation which may be part of the reason electromagnetic radiation is dangerous to humans and other life forms – we are water based. [4]

A nonprofit organization of physicians who would like to increase awareness of electromagnetic hypersensitity has more information available on their website and an opportunity to join their group: http://phiremedical.org/tag/pdfs-for-electromagnetic-hypersensitivity/

I’ve filed this under calcium on this site because EMF radiation can cause an increased flow of calcium into the interior of cells which can lead to overexcitement of the cell and may lead to cell death. People with hypersensitivity to electromagnetic radiation have measurable differences in their skin in response to exposure to EMF radiation compared to non hypersensitive people. An increase in mast cells may be part of the difference between the two groups.
