Good news/Bad news about Multiple sclerosis research
The good news about Multiple sclerosis (MS) research is that there seems to have been a major breakthrough in treatment, the bad news is that research regarding demyelinating disorders which includes MS seems to have slowed down (1) - finding a solution, a medical answer, that isn't politically approved of or one that is able to be easily patent protected may be the reason for the bad news. Finding an answer that you don't like shouldn't mean we stop asking the question. Work is progressing on genetic modification of mitochondrial DNA differences that can cause demyelination disorders and success has been seen in animal models for disease. Aging increases the risk for different types of mitochondrial DNA changes that can cause a variety of symptoms and diseases. (mitoTALENS/session by Moraes/28)
(Ubiquitin (a protein, not the same as CoQ10/ubiquinone, an electron carrying quinone involved in energy metabolism, 29) is needed for identifying which mitochondria are damaged and need to be recycled in the normal way, by autophagy/mitophagy, which involves the debris being taken into a container particle called lysosomes - imagine a cellular vacuum cleaner that can then recycle any useful material and discard any non-useful, potentially toxic material. See the session on Mitochondria in Parkinson's Disease/Youle: 28)
Cannabinoids seem to be the good news treatment for MS in humans, whether as purified extracts of medical marijuana or as the whole product which can contain many cannabinoids and medically active terpenes. An overview published in 2016 regarding the role of cannabinoids in neurology in various types of autoimmune disease: (2). An overview of the role of cannabinoids in neuroinflammatory conditions published in 2008: (3). An opinion article published in 2018 regarding the potential role of cannabidiol ( a non-euphoric cannabinoid) to improve mobility for patients with Multiple sclerosis: (4).
What is Multiple sclerosis?
Multiple sclerosis is a chronic condition that seems to be autoimmune in nature where the body is breaking down the protective coating around the branching segments between nerves. The coating is called the myelin sheath and it acts a little like the plastic coating around an extension cord. Myelin on a nerve fiber or plastic on an extension cord keeps the electrical signals on the inside and out of danger of creating sparks elsewhere along the path of the cord or nerve fiber.
What are cannabinoids?
Cannabinoids are directly involved in making strong and flexible cell membranes as they are building blocks that make up portions of the membrane, like bricks in a wall. They can also be signaling chemicals that can be activated when released from the membrane. Excess calcium inside of a cell can be a signal that causes the release of cannabinoids. Once they are released they break down into their two basic components, phospholipids and a free fatty acid, often arachidonic acid. The problem is two part - 1) both of the components of cannabinoids once they are released from the membrane can become signaling chemicals that can lead to increased inflammation, NSAID pain killers (aspirin, naproxen, ibuprofen helped reduce level of fatigue experienced by MS patients) may help block the negative effects of excess free arachidonic acid (21); 2) if too many bricks are released from the wall, then the wall may no longer function - the plastic coating on the extension cord may allow sparks through that can be a risk for an electrical fire. In the case of Multiple sclerosis the nerve damage and lack of myelin sheathing around nerve fibers causes difficulties with muscle control and the patient may have increasing difficulty walking and doing other normal daily tasks.
Preventing the increased release of cannabinoids from the membrane walls would likely to the best plan for preventing the resulting increase in inflammatory signaling chemicals they form and the reduction in membrane function. The amount of cannabinoids present can cause opposite effects, small or medium amounts can have beneficial effects while large amounts may have significantly different effects. Mitochondria are the main energy production center of the cell, where sugar is turned into a usable form of energy with the chemical shorthand name ATP or ADP. Both are phosphochemicals differing in the number of phosphate groups, adenosine tri-phosphate and adenosine di-phosphate. The amount of calcium within the cell and within the mitochondria may be different and cannabinoid can affect the movement across the mitochondrial membrane and cause differenct effects depending on the amount of calcium in each area and the amount of cannabinoids that are present. It's complicated is the short story. This article goes into a longer but still simplified description of the chemistry. (23)
And part of the point is that having adequate cannabinoids and adequate phosphonutrients and adequate but not excessive calcium are all important for cellular health and the ability to produce energy - and to not be fatigued - excessively tired all of the time. And in order to have adequate calcium but not excessive the cells need adequate magnesium and adequate protein and phosphonutrients in order to hold it ready for use - like taxicabs circling the block ready to discharge magnesium as a free ion when and where it is needed. The topic of magnesium, and the need for protein and phosphonutrients was introduced in a recent post. Magnesium blocks entry of excess calcium from being able to enter the interior of the cell, where it can cause increased release of cannabinoids from their storage positions within the cell membranes. Ibuprofen, but not other NSAIDs such as naproxen, also help reduce the amount of breakdown of cannabinoids. (pp 82-83, 24)
What are oligodendrocytes?
A type of specialized brain cell called oligodendrocytes are responsible for building or repairing the myelin sheath. Multiple sclerosis involves increased loss of oligodendrocytes. The specialized cells have calcium permeable glutamate receptors and are more susceptible to oxidative stress than average cells so they are particularly at risk for being damaged by ongoing emotional or physical stress or a traumatic brain injury. (6) Sphingomyelin is one of the building blocks of the myelin sheath, (7), and is formed by oligodendrocytes. (8)
The body is complicated and needs many/all of the nutrients for optimal health. More nutrients and other lifestyle issues that may benefit myelin production or increase risk are discussed in a list of tips for regenerating myelin, phosphatidylserine, a phospholipid, is one of the recommendations; other conditions that may include myelin breakdown besides Multiple sclerosis are also mentioned: (22).
Problems with vitamin D availability may also be involved in the body being more prone to autoimmune reactions by the immune system (attack on our own healthy cells instead of only attacking foreign or damaged cells); and on the natural building or repair of the myelin sheath. (5) And just to keep things interesting - iron is important but too much within the oligodendrocytes may increase risk for MS; polyunsaturated fats are also important but their reactivity may increase risk to the oligodendrocytes from oxidative stress; lack of Nrf2 may be involved in the susceptibility to oxidative stress in the development of MS due to damage to the oligodendrocytes; and the oligodendrocytes have an abundance of calcium permeable glutamate receptors so excess glutamate may increase risk of excess calcium entry into the cells which can lead to cell death. (8)
Summary points for protecting oligodendrocytes -
all nutrients are important, (22), but balance is also important.
Avoid excess emotional and physical stress if possible.
Adequate iron is important because the oligodendrocytes need more than average in order to be able to make the myelin sheath. Some patients may have an underlying genetic difference that leads to their needing supplementation of a well absorbed form of iron throughout their life. Genetic screening and individualized metabolic guidance may be needed for optimal treatment of patients with MS as it may have differing causes. A true autoimmune antibody/antigen has not been identified. (10)
In general however, avoid excess iron (fortified breakfast cereals and meats for example; men and menopausal women who eat large servings of very iron-fortified foods or large servings of iron rich meats can be more at risk for iron overload. Donating blood occasionally can benefit society and may help protect against the risk of iron overload for people who do not menstruate. Food sources of iron and more information about donating blood: (9) Iron overload can be a cancer risk and tends to be more common than iron deficiency in the non-menstruating population.(11))
and avoid excess free glutamate (frequently used in seasonings and naturally found in fermented products such as soy sauce. It is in many processed foods, (12)).
Eat a balance of omega 3, (22), and omega 6 polyunsaturated fatty acids.
Eat plenty of antioxidant rich foods regularly that also include Nrf2 promoting phytonutrients and other phospholipid containing nutrients. Here is some Nrf2 promoting foods and menu ideas: G10: Nrf2 Promoting Foods.
And cannabinoids or other phospholipid/phosphonutrient containing foods include these, many of which are also Nrf2 promoting foods:
Food Sources of Phospholipids and other phospho-nutrients, a partial list:
Hemp seed kernels and oil; Artemisia turanica/wormwood leaf; amaranth seed; asparagus; avocado fruit or the inner kernel, dried and powdered; beans/legumes; cardamom seeds and powder; carrots; celery stalks and leaves; cocoa beans and cocoa powder, baker’s chocolate, dark chocolate and to a lesser amount milk chocolate and chocolate syrup; coconut; cumin seed/powder; fennel seed, flax seed, pine nuts; sesame seeds, pumpkin seed kernels, squash seeds; butternut squash and pumpkin; gingko leaf; grapefruit and orange juice with the pulp; Jerusalem artichoke (this is a root vegetable rather than a green artichoke); lettuce, spinach and mustard leaves and other leafy green vegetables and herbs; nuts/peanuts, cashews, walnuts; oats; okra seeds; onion root, leek leaves, garlic; parsnip root; pomegranate seeds and pomegranate peel extract;rice, white or brown but the bran is the best source; rosemary; sorghum; sweet potato or yam; buckwheat (a seed botanically that is not wheat and is gluten free); wheat. (G.26)
The current treatments for Multiple sclerosis are very costly, and may not help all patients while also tending to cause negative side effects.
Returning to the original question - why has the ratio of research being published about demyelinating disorders declined since 2013? It is possible that the answer might be that medical marijuana or a recommendation to eat more dark cocoa and beans, nuts, and seeds is not as profitable as the older MS treatments may average $60,000 per year and newer treatments cost 25-60% more than that, (13), which would be an average prescription cost of $75,000-96,000 per year per patient with Multiple sclerosis. Good quality cocoa is expensive but can fit within most grocery budgets. Being a medical marijuana patient might cost around $12,000 per year for a patient using it several times each day. Use of ibuprofen daily might cost a few hundred dollars per year depending on the amount used and whether it was a name brand or off brand. (21) (24) (Note - long term use of ibuprofen may cause intestinal problems, ginger (about 1/2 teaspoon) can be healing for the intestines and help with pain relief as well as ibuprofen and provided better pain relief when used in combination with ibuprofen in a study with arthritis patients. Ginger may be reducing inflammation by reducing the amount of cannabinoid breakdown to free arachidonic acids and preventing transformation into inflammatory eicosanoids. (27))
Efficacy and negative side effects are also worth considering - for that $60,000-96,000/year price tag only half of the patients may gain health benefits while many will experience negative side effects in addition to needing time and copays for office visits to receive some types of treatments. Fewer than half of patients receiving interferon-β treatment were found to benefit medically and many experienced side effects. (13)
The pharmaceutical industry frequently does medical research involving new drug treatments. The use of medical marijuana for the treatment of Multiple sclerosis or other demyelinating disorders is not legal at the Federal level as the herb is still scheduled as a substance with no medical benefit. Private research in states that have legalized medical use could possibly be performed however. Enrolling patients would likely need to be by self selection though, and for comparison purposes an experimental group of patients could be given a phospholipid rich diet plan to follow and a control group of patients receiving standard pharmaceutical treatments could also be followed to compare health outcomes with the current standard of care.
How many patients have Multiple sclerosis?
More math - there are about 400,000 people in the U.S. with Multiple sclerosis and about 10,000 newly diagnosed patients each year. (14) Averaging the cost of standard treatments to $78,000 per year would mean the 400,000 patients require $31,200,000,000 per year in pharmaceutical care. Thirty one billion dollars would buy a lot of cocoa. The number of patients living with the condition globally is estimated to be around 2.3 million people. (15) If they all received treatment at the average U.S. cost it would require $179.4 billion in care.
People living farther from the equator tend to have a greater risk for developing Multiple sclerosis so vitamin D deficiency may be involved.
Looking at the global distribution map on the link does visually suggest that vitamin D deficiency may be involved - it is not as much of a risk for nations around the equator where more sunshine would consistently be available. Genetic differences may also be involved as it is more of a risk for Caucasians and people of central and northern European descent. It is rare for Inuits, Aborigines and Maoris. (14) (The Inuit native diet is rich in vitamin D from seafood sources.) A map of distribution risk across the U.S. also suggests a sunshine factor - rates below the 37th parallel are reduced compared to farther north. (15)
Sphingomyelin is found in the diet but needs to be made by the oligodendrocytes.
Why discuss eating cocoa or sources of phospholipids or vitamin D? Why not just eat sphingomyelin? We do eat some but our digestive systems break it down into smaller types of fats, (16), and then our oligodendrocytes have to rebuild it. Sphingomyelin tends to be found with cholesterol within the body, and both can affect the digestion of the other. (16)
Genetic differences may be involved in risk for MS. Variations in genes involved in Vitamin D metabolism may be a risk factor. There also may be differences in the cannabinoid metabolism involved or in other metabolic pathways.
Vitamin D can be made out of cholesterol when our skin is exposed to adequate sunshine. Genetic differences in vitamin D metabolism may be why some people are more prone to developing multiple sclerosis than others - speculatively. Genetic differences in vitamin D metabolism have been studied in relation with multiple sclerosis risk and a correlation was found however studies with supplementation have been inconclusive. (17) One nutrient solutions can not solve multiple nutrient problems - adequate iron but not too much, adequate balance of polyunsaturated fats to promote health without increasing inflammation, avoiding excess free dietary glutamate, and having adequate phospholipids and Nrf2 promoting foods in the diet may also all be important - in addition to having adequate vitamin D in the diet or from sunshine or tanning lights.
Vegetarian based diets include many foods that help reduce inflammation & protect against oxidative stress, & may save money.
Some more good news - a vegetarian based diet can provide many of those dietary factors and save money (about $750/year, (18)) compared to a meat based diet (which tends to be more inflammatory - i.e. oxidative stress promoting). More math - the economical vegetarian diet (2015 U.S. prices) was estimated to cost about $2,762/year which would add up to $6,353 million per year for the 2.3 million global population of people with MS instead of the $179.4 billion that would be needed for current pharmaceutical treatments for Multiple sclerosis. Phosholipid rich, Nrf2 promoting foods can also provide a good balance of omega 3 fatty acids and include sources of vitamin D and iron and tend to include many high quality vegetarian sources of protein such as nuts, beans, and seeds.
Cocoa has been found to reduce fatigue for MS patients and is a good source of phospholipids and Nrf2 promoting flavonoids.
Better news - cocoa, which is made from a bean that is rich in flavonoids, which are Nrf2 promoting phytonutrients, G10: Nrf2 Promoting Foods, and is a good source of phospholipids, (G.26), has been found to help reduce fatigue levels in patients with Multiple sclerosis while not increasing high blood sugar risk factors. (19)
Skip the sugar if possible, Insulin resistance may increase breakdown of the myelin sheath.
I add a spoonful of dark cocoa powder (unsweetened Baking cocoa) to my coffee - like mocha coffee without the syrup. Once you stop using sugar your taste buds adjust to not needing as much sweet taste - or add a little sugar or honey but artificial sweeteners may not be that helpful because the sweet taste is still signaling the body to increase insulin levels which then increases appetite and studies have found snacking calories are then increased -resulting in no overall reduction in calorie intake. Avoiding insulin resistance, frequently a problem with Type 2 Diabetes and Metabolic Syndrome, may also help protect against Multiple sclerosis risk as it may have something to do with the breakdown of the myelin sheath.
