HELLP, Preeclampsia, Antiphospholipid Antibodies and Basic Triplets

Clotted RBCs in Capillary

Some of my research involves the unique properties of milk and the development of the immune system, so I talk to medical people, lactation researchers and occasionally discuss the control of inflammation involved in ovulation, fertilization, implantation, gestation, labor and lactation.  It is clear to me that there are a few trends in disruption of these pregnancy processes resulting from the modern increase in inflammation and gut-related problems linked with immune tolerance.  Infertility is increasing, because women are becoming more chronically inflamed.  Miscarriages and premature births/low birth weight are increasing, because chronic inflammation enhances labor.  Pre-eclampsia (high blood pressure and protein leaking into the urine) results from chronic inflammation and omega-3 fatty acid depletion.  Now an even scarier form of pre-eclampsia, HELLP (Hemolysis, Elevated Liver enzymes, Low Platelets) is on the rise.  I want to discuss HELLP to put all of these pregnancy-related problems into perspective.

HELLP, Cause and Cure Unknown?

HELLP is an autoimmune disease and I have repeatedly discussed the cause of autoimmune diseases:  1) inflammation, 2) deficiency of Tregs (immune tolerance) and 3) antigen basic triplets (antigen presentation).  When HELLP was recently brought to my attention with a sudden rise in local hospitals, I decided to see if it could be easily explained and cured, just by examining the available medical literature.  Wikipedia indicated that the cause and cure was not known and that was confirmed by local doctors, who just treat the symptoms by early deliveries and long stays for the babies in neonatal intensive care units.  My work was cut out for me.

Autoimmune Disease with Unknown Autoantigen 

An examination of the symptoms, rupture of blood cells (fibrin production), liver damage, clotting (low serum heparin), high blood pressure (capillary apoptosis), proteinuria (low heparan sulfate (HS) to prevent protein loss), pointed to some obvious treatments and the causes.  Infertility is often treated by in vitro fertilization/insemination, supported with aspirin and heparin injections to maintain gestation.  These treatments are consistent with high levels of chronic inflammation that block implantation and stimulate labor.  Infertility is also associated with antiphospholipid antibodies.  A closer look at the antiphospholipid antibodies showed that they were directed against β₂-glycoprotein-I.  So, I expected the β₂-glycoprotein-I protein to be the original target for the antibodies, the initiating antigen, but when I looked up the sequence of that protein, it lacked the expected basic triplet I have found in all  other autoantigens and allergens.  This meant to me that there was a different protein with a related sequence that started the HELLP autoimmune disease.

Attack on P-Selectin Starts Immune Autoimmunity

I checked for other proteins with related sequences and basic triplets (RKR in the carboxy terminal sequence below), and found P-selectin that is produced most abundantly in liver and on the surface of blood cells.  A quick search of the literature showed that P-selectin reacts with anti-phospholipid antibodies and has a pair of basic triplets that enhance immune presentation and make this protein a strong candidate for becoming an autoantigen.  Antibodies against P-selectin will cause clotting as seen in HELLP.

Antibiotics and Liver Damage

I suspect that HELLP is caused by a combination of liver damage and prior exposure to antibiotics (or common drugs that have antibiotic activity) that cause gut dysbiosis, i.e. loss of gut bacteria that stimulate development of the suppressive part of the immune system, e.g. deficiency in regulatory T cells, Tregs.  Examples of the type of liver damage that may lead to HELLP are excessive consumption of alcohol (alcoholic fatty liver) or high fructose corn syrup (non-alcoholic fatty liver).

HELLP from Cause to Cure

• Diet and/or infection causes liver inflammation.
• Antibiotics/drugs and/or processed foods lacking prebiotic fiber produce gut dysbiosis.
• Lack of gut bacteria needed for development of the immune system in the gut produces a deficiency of Tregs and dysfunction of immune tolerance.
• Liver inflammation, deficiency of Tregs and availability of antigens with basic triplets leads to antibodies against liver proteins.
• Chronic inflammation leads to decrease in HS production and leaky kidneys/proteinuria.
• Chronic inflammation/liver damage produces fibrin production.
• Fibrin production and low HS enhances clotting and leads to apoptosis/cell death in capillaries.
• Loss of capillaries leads to high blood pressure.
• Cure of HELLP, anti-phospholipid antibodies and pre-ecampsia, involves lowering chronic inflammation (aspirin and heparin treatment) with an Anti-Inflammatory Diet, fixing vitamin D deficiency, increasing omega 3/6 ratio,  and repairing gut dysbiosis to fix immune tolerance.
• Without these interventions, HELLP symptoms will become more severe, especially in subsequent pregnancies and additional autoimmune diseases will develop.

Dr. Oz on Gut Flora Repair

---  the other 200 posts  ---

Where is the hippo? Trying to repair a complex community of a couple of hundred different species of bacteria by just changing diet, is like a zoo trying to add hippos by building a new enclosure and supplying it with fodder. You can wait and wait, but you can't add new species without adding new species. Hippos don't appear by spontaneous generation and neither does E. coli or other gut bacteria. You have to ship in hippos from other zoos and after antibiotic-induced extinction of gut bacteria, you have to introduce or eat missing species of bacteria. Also just adding probiotics will not provide a lasting fix for damaged gut flora any better than adding more elephants or giraffes will improve the diversity of a zoo lacking hippos.

I am amazed that Dr. Oz and the medical industry can encounter symptoms of dysfunctional gut flora, e.g. constipation, food intolerance, autoimmunity, allergy, that are preceded by antibiotic treatment and not address the compromised species diversity of the gut. The involvement of gut bacteria in immune system function is documented in the biomedical literature. The lasting impact of antibiotics on gut bacteria is known. Then why do Dr. Oz and the rest of the medical industry just recommend probiotics, a half dozen different species of bacteria found in fermenting dairy products (think elephants and giraffes), to repair a decimated gut bacterial community? They seem to be perplexed and ask, "Where is the hippo?"

Generalizations about Gut Bacteria

Each healthy human maintains a subset of a couple of hundred of the couple of thousand different species of bacteria found in humans around the globe. The diverse community in each individual may differ in species, but has approximately the same complement of genes in people sharing the same diet.

• 1-200 different species of bacteria per person
• 1-2000 different species of human gut bacteria
• 1 million different genes among the different bacteria
• Most genes are involved in digesting plant carbohydrates, i.e. soluble fiber: inulin, pectin, fructans, algal sulfated polysaccharides, etc.
• Diet diversity, e.g. the Modern American Diet, reduces the diversity of the gut bacterial community, presumably because the rapid change in foods permits survival of only generalist bacteria that can digest many different foods.
• Simple diets produce gut flora diversity, but only if there is access to diverse bacteria.
• Health may result from diverse gut flora developed from a simplified diet and ample bacterial resources.
• Obesity and other diseases may result from simplified gut flora developed from a changing, complex diet and a sterile environment/isolation.
• Vegan and paleo extremes can lead to healthy gut flora diversity, if the gut bacterial community is permitted to adjust to the diet composition by avoiding rapid changes and providing diverse bacterial sources.
• Meat contains complex polysaccharides, e.g. glycosaminoglycans, such as chondroitin sulfate and heparan sulfate proteoglycans, which are bacterial fodder equivalent to soluble fiber.
• Probiotics are unique bacterial species that do not persist in the gut of adults, but dominate the gut of milk eating babies and stimulate development of the gut and immune system.
• Probiotic bacteria can temporarily provide developmental signals for immune system development that are normally provided by a healthy gut flora.
• Antibiotics cripple gut flora needed for development of the immune system.
• Common medicines have significant antibiotic activity and modify gut flora.

Damage to Gut Flora is Not Repaired by Diet Alone
There is little or no effort being made by the medical industry to develop approaches to repair gut flora damaged by disease, unhealthy diets or medical procedures. This is similar to a surgeon stepping away from removal of a diseased organ without closing the wound. Antibiotics leave a gut flora that will remain permanently damaged without systematic, monitored repair. It might also be suspected that disruption of gut flora by antibiotics and the introduction of large amounts of new foods, such as high fructose corn syrup and vegetable oils may contribute to or cause the modern prominence of obesity. After all, gain or loss of weight changes gut flora, obese individuals have damaged gut flora, and trading gut flora between fat and lean animals, trades weight gain/loss behaviors.

Sources of Bacteria to Repair Damaged Gut Flora

• We must eat new bacteria in order to replace bacterial species lost by antibiotics or unhealthy diets.
• Probiotics -- bacteria that aide gut function, commercially from dairy fermentation
• Fresh vegetables -- bacteria are on the surfaces of plants unless the vegetables are cleaned or cooked
• Fermented foods -- Bacterial growth leading to acid or alcohol production has beed used in the preparation and storage of many foods and provides a rich bacterial resource.
• Environment -- Bacteria are transferred to our hands and face from other people, pets and surfaces, unless hands and the body are continually washed. Sanitizers and frequent washing of hands and surfaces eliminate acquisition of environmental bacteria to repair damaged gut flora. Social isolation and hygiene block repair of gut flora.
• Replacement -- experimental replacement of damaged with healthy gut flora (fecal transplant) has been very effective in curing many diseases without significant risks, but is restricted by the medical industry.

Dr. Oz on Sweeteners: Sugar, Fructose, Insulin/Resistance, AGE, FattyLiver

….All 190 posts here….

I was shocked when Dr. Oz recommended a snack made with agave syrup. I had seen a previous program by America's representative of the medical industry in which he revealed the hazards of agave syrup as a new source of fructose. Now he just skipped over the use of this fructose syrup as a "natural" sweetener, even though it is even less healthy than high fructose corn syrup, HFCS. There seems to be a lot of deliberate confusion about sweeteners and since I am trained as a carbohydrate chemist, I will try to tell it as I see it.

General Information 

• Carbohydrates are not needed in your diet, since your liver can make all the blood sugar that you need from protein. Most diabetics can benefit from a low carbohydrate diet. 
•  Glucose, the blood sugar, is primarily responsible for turning on insulin production, so sweeteners (glucose, sucrose, HFCS, corn syrup) or dietary carbohydrates (starch, e.g. cereal, rice, pasta, potatoes, bananas) that are readily converted to glucose, cause blood insulin levels to rise. 
•  Fructose in any form (HFCS, sucrose, agave syrup) contributes to liver damage. Fructose is the most chemically reactive sugar. 
•  Artificial sweeteners, especially in soft drinks, do not contribute dietary calories, but they apparently increase insulin production and contribute to hunger, eating and obesity. 
•  Insulin production removes glucose from the blood, i.e. lowers blood sugar, by increasing glucose transport into fat cells. If glucose is in your blood, but insulin is not present, e.g. type I diabetes, then you get thin. If glucose is in your blood and insulin is present, then you get fat. If you are fat and glucose is still high in the blood and insulin is present, then the fat cells will die unless they shut off the insulin response, i.e. insulin resistance. Lowering the amount of carbohydrates, sweeteners/starch, in your diet makes it easier to control blood sugar levels and avoid hunger. 
•  Decreasing dietary carbohydrates means that calories have to be present in some other form and the answer is saturated fat. Most polyunsaturated fats, e.g. vegetable oils, except olive oil, are not healthy. The fats in meat, butter, eggs and coconut oil are the healthy choices supported by the biomedical literature, and along with vegetables, form the foundation of a healthy, anti-inflammatory diet. 

Central Metabolism Started with Fructose not Glucose 
All organisms convert sugars through a common series of enzymatic steps, called central metabolism, to a simple, three-carbon compound called pyruvate. Pyruvate can be used as a source of energy in mitochondria in the presence of oxygen or converted into alcohol or acids in various forms of fermentation. No matter what sugars are used, e.g. glucose, galactose, mannose, they are all converted in cells into derivatives of fructose. Thus, fructose is common to all organisms and can be considered to be the most primitive. So why is glucose usually considered to be the the start of central metabolism and why is dietary fructose dangerous?

Fructose is too Reactive to Transport 
The first cells used fructose as the starting material to make the building block molecules of cells, e.g. carbs, proteins, fats, nucleic acids, and energy in the form of ATP. Multicellular organisms, such as animals and plants had to move sugars from cell to cell. It would be obvious to transport fructose, since all other molecules could be converted into fructose, but the problem is that fructose is too chemically reactive, i.e. it reacts with proteins to form AGE. It is for that reason that fructose is converted by cells into glucose, which is less than one tenth as chemically reactive. In plants, the reactive groups of glucose and fructose are bonded together to produce sucrose, table sugar, which is much less reactive and can be transported in plant vessels at very high concentrations.

High Blood Sugar is Bad, High Fructose is Worse (AGE-ing) 
High levels of blood sugar, glucose, react with proteins to produce advanced glycation end products, AGE. Fructose in the blood produces these inflammatory compounds more than ten times faster. That is why fructose is a bad sweetener for diabetics. Eating fructose, e.g. agave syrup or sucrose, doesn't directly raise blood sugar/glucose levels, since it raises blood fructose levels, which is worse.

Fructose Fattens Livers 
Fructose is rapidly absorbed in the intestines and transported to the liver. The blood vessels of the liver remove fructose from the blood and it is rapidly converted into fat. Fructose in sweeteners has now surpassed alcohol as the major source of liver disease.

Sweeteners
Fructose is ten times sweeter than glucose, and that is why cheap forms of glucose, such as corn syrup, are treated with enzymes to convert some of their glucose into fructose to produce high fructose corn syrup. Corn syrup is not as sweet as pure glucose, because the syrup contains a mixture of short chains of glucose of different lengths, and the chains decrease in sweetness with length. By changing some of the glucose into fructose, the HFCS can be made as sweet as table sugar, sucrose. Corn subsidies keep corn syrup cheap and make HFCS very profitable. Unfortunately, the HFCS contains fructose and therefore it has the liver toxicity and AGE-forming inflammation of fructose.  Agave syrup is like HFCS on steroids.

Agave Syrup is Fructose 
Agave syrup contains fructose produced by industrial processing of the fructose polysaccharides, inulin, in agave extracts. I cannot understand why anyone would use this commercially processed fructose as a sweetener. It doesn't raise blood sugar as much as sucrose, because there is much more fructose than sugar (like very high fructose corn syrup) it raises blood fructose levels instead, which is much, much worse.

Sugar Makes You Hungry 
The human body can only use simple sugars, e.g. glucose, fructose, sucrose, or starch. Body enzymes convert sucrose into fructose + glucose, and starch into glucose. Other carbs, such as soluble fiber, are only digested by gut bacteria in the colon. The conversion of starches to glucose begins with enzymes in saliva in the mouth and is completed in the upper part of the digestive tract. Starch should be considered as a simple sugar, because it causes a rapid rise in blood sugar, just like glucose. It may actually be faster than table sugar. The rapid rise of blood sugar causes a rapid increase in blood insulin, which in turn rapidly removes sugar into fat cells. The rapid rise and fall of blood sugar provides the experience of hunger. That is why cereal, e.g. oat meal, in the morning produces intense hunger just a few hours later. Actually, oat meal is not quite as unhealthy as most cereals, because it also has some soluble fiber to feed gut flora. A protein and fat breakfast, e.g. bacon and eggs, does not produce rapid hunger, because it does not produce a large insulin rise and glucose fall.

Insulin Resistance is Better than Death by Glucose 
As fat cells accumulate glucose as a result of blood sugar transported into the cells in response to insulin, more and more of the glucose is converted into fructose and on to pyruvate. The pyruvate accumulates in mitochondria and ATP production is saturated. This is potentially lethal for the cells, because the conversion of pyruvate into ATP is accomplished by removing high energy electrons as the pyruvate is converted to carbon dioxide. The high energy electrons accumulate in the inner membranes of the mitochondria and if they are not systematically converted to low energy electrons and dumped onto oxygen to produce water, reactive oxygen species, ROS are produced and the result is inflammatory oxidative stress. Antioxidants would be needed to protect from major cellular and organ damage. The cells protect themselves by responding to the accumulation of high energy electrons on the mitochondria by shutting down the response to insulin and blocking further intracellular glucose accumulation. This is insulin resistance.

Carbs: Never too Low 
Dietary carbs, such as sugars and starches are not needed, because the liver can convert protein into glucose. Thus, diabetics, who have a hard time balancing their dietary intake of carbs with the insulin that they inject, can simplify the process by routinely eating less carbs spread through many meals and triggering some glucose production by the liver. Craving for carbohydrates/sweets can be dramatically reduced simply by eating fewer carbs and avoiding insulin production that can lead to more dramatic swings of blood sugars and hunger. Using this strategy, I am hungry less than once a week.

Healthfulness of Sweeteners 
 --from Most Healthy....

• Stevia - is a diterpene glycoside (I previously made the silly error of listing it as a protein) (erythritol, another simple sugar alcohol is added to make the stevia granular) that is sweet, doesn't raise blood sugar, no insulin spike and no AGE 
• Glucose - raises blood sugar, spikes insulin and produces AGE 
• Xylitol - is a sugar alcohol that inhibits dental bacteria, doesn't raise blood sugar, no insulin spike or AGE 
• Corn Syrup - raises blood sugar, spikes insulin, produces AGE, low sweetness  
• Sucrose - raises blood sugar, spikes insulin and produces AGE, and liver damage 
• Honey - is half fructose and half glucose, raises blood sugar, spikes insulin, produces high AGE and may damage liver  

• Artificial Sweeteners, aspartame, sucralose, saccharin, etc. - don't raise blood sugar or produce AGE, but may have other risks, including hunger 

• HFCS - is high fructose corn syrup, raises blood sugar and spikes insulin, produces very high AGE and causes liver damage 
• Fructose - doesn't raise blood sugar or spike insulin, produces very high AGE and causes liver damage,  does not produce satiety and may encourage consumption of other sugars 
• Agave Nectar - is mostly fructose, doesn't raise blood sugar or spike insulin, produces very high AGE and causes liver damage

Low Carbs Lower Triglycerides

Blood Triglycerides Depend on Diet Carbs, not Fats

I don’t know why the medical community keeps pushing the low fat diets to modify blood lipids. The medical literature shows that a low fat, high carbohydrate diet (more than 50 grams of starch/sugar in a meal) produces high triglycerides, and a low carb diet ( less than 50 grams per meal), regardless of saturated fats and meat, produces lower triglycerides.

In seems reasonable that fats in the diet should mean fats, triglycerides, in the blood, but that ain’t so. It’s the rise in blood insulin in response to a rise in blood sugar due to high glycemic index foods in a meal, that yields high blood triglycerides.

The low carb, low triglycerides facts of life were brought to may attention by my wife’s blood chemistry. She knows better, but refuses to follow my preacherly suggestions about an anti-inflammatory diet. She follows most of the use of supplements and prohibitions about vegetable oils, but loves carbs. She eats two thick slices of bread in a sandwich and I cut a thinner slice and eat mine open-faced. I can’t eat her pancakes or French toast. Ok, I eat lots of dark chocolate, but I don’t have flavored syrup in my lattes.

She was stressed by a high triglycerides (292 mg/dl) in her blood work and her doctor wanted to start her on meds. I was sympathetic. Not really. I actually said, “carbs, carbs, carbs,” until she threatened me. I nagged heavily to just junk the junk and wait on the meds. She started counting grams of carbs with each meal. Actually she tried to average over the whole day, I nagged, she finally relented and stuck to the plan. No more than 50 grams of carbs in any meal. (I think 30 grams, would actually be better.)

One month later, her blood work showed triglycerides down 57% to 127 mg/dl. Individual results may vary, but this is pretty straightforward. Carbs are important -- avoid them. The food pyramid is for chumps. The highest glycemic food you will encounter is a French baguette (95), compared to pastas in the 30s or table sugar at 70.

The facts are:

• Saturated fats in meat are no big deal, and much better than...
• Vegetable oils (most are rich in omega-6 oils, except olive oil) are inflammatory.
• Fish oil (omega-3 DHA/EPA) is anti-inflammatory (unless there is also too much vegetable oil.)
• Starch and sugar increase blood triglycerides and are only needed to gain or keep body fat. Losing weight is much easier without starch/sugar.
• Most people are deficient in vitamin D and C (even with plenty of solar exposure).
• High fructose corn syrup is ten times more damaging than starch/sugar, and is especially bad for diabetics. It doesn’t raise blood sugar as much as starch, it just causes damage, e.g. glycation, at an extraordinarily high rate. It also ages skin by accelerating cross-linking of collagen. Very bad stuff even in fruit juices.
• Eating plant anti-oxidants protects unsaturated fats as they pass through the oxidizing environment of the stomach, so nuts are better unroasted and eaten with veggies.

Diet, Nutrition and Health

These are my generalizations (some would say prejudices) from 40 years of experience in plant biochemistry and molecular biology:

Plant Secondary Compounds Are Defensive and Toxic

The development of plant secondary compounds (all of the compounds that are not part of metabolism or structures) is in response to pathogens, herbivores and pollinator/disseminator attractants -- development of these compounds has nothing to do with humans. Examples: Nicotine and caffeine are very toxic to herbivores and are present in plants for protection. Humans learn to play with toxic plant chemicals, just as they have learned to play with fire and explosives.

Plants Are Not There For Us

People have learned to exploit local plants for protection against local human pathogens, but there is no selective advantage to plants (except for domesticated plants) for useful plants to grow near humans. This logic would suggest that rats and mosquitoes, that flourish near human habitations, are there because of their human utility. Human live near places were useful plants grow.

Grains Are Unhealthy

One of the biggest problems with food processing is separating the inflammatory parts = starch and omega-6 oils, from the nutritive parts, the so-called anti-oxidants, vitamins, proteins, etc. Grains, even so-called whole grains, are simply too enriched for starch and inflammatory oils to be healthy. They are not safe to eat in large amounts. Leafy plant parts are healthy, but even those parts are not good in large amounts from a single plant species. Humans are browsers, because the plant secondary compounds are uniformly toxic, but can be tolerated better in a mixture of different toxicities.

Starch Is Inflammatory

Starchy foods should be treated like a fish. The starch should be pared away and discarded, like the fish gut and bones. (The guts and bones could actually be processed to make them nutritious. Not so with the starch. The starch should be fermented.) The potato skin should be eaten and the rest discarded, just as an aphid secretes as honey dew the extra sugar it sucks in from a plant leaf.

Cereals Are Inflammatory

Breakfast cereals are a dietary abomination. They contribute immensely to obesity, inflammation and chronic disease. Oatmeal for cardiovascular health is a total fraud. The fiber might be useful, but the high starch causes cardiovascular disease. Grains/cereal are the foundation of the chronic disease pyramid.

Fructose is Toxic

Fruit juices are another fraud. The juice (fructose) should be removed and discarded. The fructose is very unhealthy. Mice are given type II diabetes for research purposes by feeding them fructose (especially high fructose corn syrup.) Fructose is avoided in the beef industry, because it causes rapid cross-linking of collagen and leads to tough meat. The same thing happens in humans who eat fructose, it causes aging of the skin and other tissues. High fructose corn syrup is a commercial addiction -- it is hugely profitable as a sweetener -- and that is why it is still used, even though it is grossly unhealthy. It will eventually be removed from the market after the industry is protected from subsequent law suits. It is equivalent to the tobacco industry -- too lucrative to eliminate.

Phytic Acid

The active ingredient in fiber that provides its benefits is phytic acid, the same chemical that people are trying to eliminate. Phytic acid acts as a chelator. I don't think it is actually a problem. The problem comes from extracting cations from the phytic acid before it is eaten. Phytic acid should go in saturated, so that it doesn't contribute to deficiencies. The actual problem is that the diet is already low in minerals, because of eating processed foods that are mineral deficient.

Enzymatic Detoxification: P450, Glycosylation and Secretion

Humans are adapted to plant secondary metabolites by the abiltiy to enzymatically detoxify [using p450 and glycosylating (adding glucuronic acid)] and secrete the toxic compounds. These chemical modifications that occur in the intestines and liver are usually effect. They also work on drugs and that is how we eventually clear these compounds from our systems. Grapefruit and black pepper inactivate these enzymes and alter the way we metabolize plant toxins and drugs. The detox enzymes can also convert innocuous compounds into toxins and carcinogens. That conversion is the basis for using liver enzymes in the Ames Test for carcinogens. The activity of the enzymes is dependent on recent diet, so it would make sense to gradually change the amount and type of vegetables that are eaten in a meal to permit the detox system to adjust.

Glucose and Insulin Cause Fat Accumulation

Fat accumulation is dependent on dietary carbohydrates and insulin. Fat and serum lipids accumulates with a high carbohydrate diet and decrease on a low carbohydrate diet. This is more important than the number of calories consumed.

Inflammation Not Serum Lipids Cause CVD: Statin Are Unnecessary

Inflammation is the source of chronic degenerative diseases. Serum lipids are only secondary factors. Statins lower serum lipids, but do not impact cardiovascular health unless they also lower inflammation. Lowering inflammation lowers serum lipids and decreases cardiovascular disease. Statins appear to be a very expensive way of treating cardiovascular disease dependent on their side effect on inflammation. Modest dietary and lifestyle changes are much more effective, cheap and safe than statins.

Hazards of Air Travel: DVT

Deep Vein Thrombosis (DVT) -- clots in your veins

Air travel during the holidays means sitting quietly for hours while the blood pools in the major veins of your legs. This is a test. How have you been eating lately? If you stuck to an anti-inflammatory diet and got your exercise, just fidgeting a little and flexing your legs ever once in a while should avoid clots. If you are the typical sedentary American with an inflammatory diet, then worry. One tenth of you will typically have clots in your leg veins after a long flight.

Rolling stones gather no moss, and the same is true for rapidly moving red blood cells (RBCs). Keep them moving and they don’t stick together. Slow down RBCs traveling along sticky vessel walls and you have problems. RBCs have no nuclei and since the intracellular secretory system originates from the outer membrane of the nucleus, red blood cells don’t secrete anything. RBCs just age until they are removed by the spleen. So RBCs just move passively with the rest of the blood.

Another player in clot formation is the platelet. Platelets are cell fragments. They are formed by extrusion and shearing. The process is like bubbles forming as you blow air through a child’s bubble wand. Cells in the bone marrow are squeezed through a grid and the extruded fingers of the cells are blown away in the blood flow as platelets. The electron micrograph shows a platelet between and RBC and a white blood cell. Platelets don’t have any active cell machinery, so they are just little bags containing secretory vesicles that can be released by triggering of receptors on their surface. Platelets are only good for one shot of release.

Platelet release of secretory contents is triggered by norepinephrin, ADP and PGI2, an inflammatory prostaglandin produced from the omega-6 arachidonic acid. Norepinephrin is one of the fight-or-flight hormones that prepares the vascular system for damage control. ADP is released from other activated platelets and insures that isolated platelets are not randomly activated.

One of the proteins released is platelet factor 4. I have illustrated PF4 and the strip of basic amino acids (blue) that girdles the protein are readily apparent. PF4 binds strongly to heparin. Since the clotting process is normally under heparin inhibition, PF4 release from platelets removes the heparin inhibition and promotes clotting. ADP is also released and promotes further activation of other platelets.

Clot formation occurs in response to stress (norepinephrin), damage (vascular inflammation) and a consensus of platelets (ADP). Chronic inflammation can mimic this combination of signals through its impact on heparin metabolism. My research suggests that inflammation lowers heparin synthesis. An example of this effect is kidney damage caused by diabetes. High blood sugar causes inflammation of the kidney blood vessels, this reduces heparin production and since heparin lining the vessels is needed to retain proteins as blood is filtered in the kidney, protein is lost into the urine, i.e. proteinuria. Similarly, chronic inflammation can disrupt the blood brain barrier that is also made up of heparin.

A major source of chronic inflammation is an inflammatory diet. A recent research study indicated that a typical inflammatory American diet leads to elevated risk for deep vein thrombosis. Alternatively, an anti-inflammatory diet rich in B vitamins and omega-3 oils minimized DVT. Saturated fats had no impact, consistent with the lack of evidence supporting the shift from saturated fats to toxic omega-6-rich polyunsaturated vegetable oils.

So, the best thing that you can do to protect yourself from clots when you travel over the holidays, is to eat right and get your exercise, before you travel. Avoid starch (in large amounts) and polyunsaturated vegetable oils (except olive oil.) Corn oil, soy oil, cottonseed oil and safflower oil are particularly inflammatory. Eat plenty of veggies and fruits and enjoy the turkey and cranberries. Make sure that the only sweeteners used are sugar and honey (avoid high fructose corn syrup.) Light corn syrup is the stealth form of HFCS -- it may be lower in calories, since fructose is sweeter than sugar, but it is highly inflammatory! (Research also indicates that fructose causes premature wrinkling and skin aging, by enhancing the crosslinking of collagen. HFCS also causes type II diabetes in lab animals.)

More Inconvenient Truths

I am writing this shouting summary of bottom lines in response to recent good news and bad news. The good news is that Michael Pollan is speaking in Boise, near my home town. The bad news is the recent press coverage of the JUPITER study on statins.

Michael Pollan is one of my heros. He speaks simply and clearly about the role of national agriculture policy in promotion of hazardous foods that lead to profits in the healthcare industry, but death and disease for the US population. Pollan also provides wise advice to solve our problems.

A new statin, Crestor, was shown in the JUPITER study to significantly reduce the risk of cardiovascular events, e.g. heart attacks, stroke, death, in a study population with normal LDL and elevated C-reactive protein, an indicator of inflammation. The press supported the drug maker’s interpretation that the statin provided benefit by lowering LDL in a population with chronic inflammation. What is missing is the clarification that lowering LDL is unimportant in reducing cardiovascular risk. Lowering inflammation lowers cardiovascular risk and there are more appropriate ways of lowering inflammation than using very expensive drugs. It is much cheaper, healthier and effective to switch to an anti-inflammatory diet and lifestyle!

After reading thousands of articles in the biomedical research literature, here are a few of my obvious bottom lines. Diet affects your health and the most fragile stages of development and most fragile organs, are the most sensitive to abuse. Therefore, damaging diets are most harmful to fetuses, newborns, brains, the cardiovascular system and reproductive systems.

• Formula promotes inflammatory bacteria in newborn guts resulting in lower intelligence, disrupted immunity, infections, allergies, obesity, degenerative diseases and autoimmune diseases. Breastfeeding is the only anti-inflammatory answer for infants.
• The US diet (hyperglycemic starch/sugar, high omega-6 to omega-3 fatty acid ratio, HFCS, low vegetable anti-oxidants, low vitamin D/sun exposure, low vitamin C, grain-fed meat instead of fish) is inflammatory.
• The Mediterranean Diet (small portions of starch, low omega-6 oils, no HFCS, high vegetable anti-oxidants, routine sun exposure, adequate vitamin C, fish and grass-fed meat) is anti-inflammatory.
• Inflammatory diets lead to infertility (female and male), problems during pregnancy (e.g. preeclampsia is an omega-3 fatty acid deficiency) and prematurity/low birth weight.
• Mental illnesses of many different types benefit from anti-inflammatory diet and lifestyle. Diet-based brain inflammation may be a major predisposing factor.
• All of the prevailing drug therapies for cardiovascular disease benefit from anti-inflammatory diet and lifestyle. Most of the drugs that reduce cardiovascular events rely on anti-inflammatory activities. Inflammation is the primary cause of cardiovascular disease, not elevated blood lipids/cholesterol.
• Vegetable oils (corn, soy, cottonseed, safflower) are rich in omega-6 fatty acids and are dangerously inflammatory. These polyunsaturated oils are less healthy than saturated fats. Olive oil is the most healthy.
• Reasonable routine exposure to the sun could eliminate inflammatory vitamin D deficiencies.
• Obesity is inflammatory, but diet-based inflammation may also be a major contributor to obesity.
• Genetic predisposition to specific diseases is triggered by diet-based chronic inflammation.
• Diseases and disabilities associated with aging are symptoms of mismanaged chronic inflammation typically resulting from decreasing muscle mass and increasing fat.
• Sensible diet and lifestyles could dramatically improve quality of life and reduce healthcare expenditures in the US.

Prescription: eliminate vegetable oils, eliminate HFCS, eliminate trans fats, use olive oil, reduce starch, eat vegetables, eat more fish and less meat, get daily sun, use fish oil supplements, get frequent muscle-building exercise, and stay lean.

Inflammation Score

Most people need some feedback to monitor the impact of their diet and exercise on their health. I tried to point out some of the major contributors to chronic inflammation with a little check list. See how you score (choose one of the list for each category) and give me your feedback on the how you think each part contributes to inflammatory diseases.

If you smoke, add an extra 15 points

Add ‘em up. How much are you stoking the inflammation furnace?
0-5 Cool! You will never look your age.
6-10 You are getting warm. Hope that you don't have any genetic predispositions to disease.
11-15 You may postpone inflammatory illness until middle age. The flame is lit. Pick your disease.
16-25 If you aren’t showing a chronic disease, you will soon.
26+ You can reverse your disease symptoms with the inflammatory diet and exercise.

Cartilage as Rejuvenation

I have studied cartilage secreting (chondrocytes) for the last few years. Chondrocytes are normally derived by differentiation of mesenchymal stem cells (MSCs) that grow in the bone marrow. MSCs can differentiate to produce bone secreting cells (osteoblasts), muscle cells (myoctes), fat cells (adipocytes) and insulin-secreting cells (beta-pancreatic islet cells.) I chose to study a rat chondrosarcoma (RCS) cell line, because this is a type of cell that shares the properties of many other important cells and it will continue to grow in cell culture. Thus, I can dilute some RCS cells in a solution with all of the nutrients required for growth and the cells will stick to the surface of the plastic dishes that I use, grow and differentiate. If you stain the cultures for cartilage, you get the following micrograph.

At first the cells stretch out and move about the surface of the dish. Then they become progressively less adhesive to the surface and more spherical as they start to produce and secrete the polysaccharides (glycosaminoglycans, such as chondroitin sulfate and heparan sulfate) and proteins (collagen) of cartilage. Finally they produce thick layers of cells that are separated and embedded in cartilage. After a little more than a week in culture, the cells are moving through the cartilage matrix by enzymatically degrading the cartilage ahead of them and secreting new cartilage in their wake. The cells that eat their way to the dish surface separate the cartilage layer from the dish and the colonies of cells begin to slough off from the dish surface. Normal chondrocytes would eventually stop dividing under culture conditions, but the cancer line that I use continues to grow quite happily and can be diluted and plated continuously. Chondrocytes in cartilage live in cavities within the cartilage and are surrounded by heparan sulfate attached to proteins of their cell membranes, i.e. heparan sulfate proteoglycans.

Cut cartilage will grow back together as the chondrocytes mine, secrete and gradually knit the two surfaces together with strands of new cartilage. Movement through and renewal of cartilage, e.g. in the connective tissue of skin, is restricted if the collagen fibers that are assembled outside of the secreting cells are cross-linked. This is why sunbathing ages skin. High fructose corn syrup also accelerates cross-linking. This cross-linking is also what makes meat less tender. The cross-linking and toughness can be measured by inserting fluorescence-measuring probes into meat, because the protein cross-links fluoresce in UV light.

A consequence of the development of chondrocytes on the ends of bones, is that the nutrients for the cells change. Initially the chondrocytes enjoy the abundant glucose and oxygen of the blood stream and gradually they are remove further from blood vessels. (Note that cartilage actively inhibits vascularization, so there are no blood vessels in cartilage. This lack of blood vessels and associated enhanced risk of disfiguring infection, is a reason to discourage piercings that involve cartilage.) Chondrocytes snug in their little cartilage cavities no longer eat sugar or breath oxygen, they dine on cartilage and ferment.

What happens if you expose mature chondrocytes to a new source of rich nutrients? I think that the answer is rejuvenation. Quite literally, the chondrocytes regress and return to the lifestyle of their youth. Instead of producing mature, weight-bearing, dense cartilage, these rejuvenated cells start to produce the weaker matrix of their youth. This weak cartilage is readily damaged by abrasion and is not suitable for joint surfaces. This is one of the consequences of arthritis. Inflammation of cartilage brings rejuvenating, damaging nutrients to chondrocytes. The mechanical damage leads to destructive cycles of further inflammation.

Chondrocytes in cartilage also respond to mechanical stress and this stress maintains their maturity. Persistent weight bearing at the same orientation leads to bone production. Thus, after joint injury it is important to use the correct regimen of rehabilitation to maintain mobility of the joint and mineralization of the bone.
