A recent article, posted online, described a woman in her 50s who had traditional symptoms of COVID-19 at first but then developed an altered mental state. She was studied by MRI that reportedly showed capillary hemorrhage (no stroke) involving a part of the brain known as the thalamus. Another article reported the radiological study of 56 patients with the thiamine deficiency brain disease known as Wernicke encephalopathy (WE). MR imaging findings reported that “80 % of the patients had evidence of symmetrical lesions in the medial thalami”, part of the brain which might justifiably be referred to as the part that computes a defensive, adaptive response.

Experimental thiamine deficiency in animals is a classical model for the study of metabolic encephalopathy and selective cell loss of the brain resulting from a generalized low-grade oxidative deficit. Late stages are characterized by hemorrhage in the brain and on day 13 of the experiment, tissue damage and hemorrhage was found in the thalamus. In a study of experimentally induced thiamine deficiency in mice, petechial hemorrhage was found in the brain tissues. Of course, it is not possible to tie these references together to indicate that the encephalopathy resulting from COVID-19 is due to thiamine deficiency. However, taken as a whole, they support the idea that the mental symptoms might well be a reflection of a brain energy deficit arising from a failed initiation of an automatic, defective defense program.

The question then arises: is there evidence for thiamine deficiency in other virus diseases? Wernicke encephalopathy has been described in AIDS patients, a disease that has been associated with viral cause. However, the lifestyle and diet of such patients is often questionable and may confuse the issue. Chronic hepatitis B, a viral disease, is an international health concern that results in liver failure and death. Indirect evidence suggested a relationship between thiamine treatment and aminotransferase levels (a laboratory test that indicates faulty energy metabolism), a report begging for clinical trial with megadose thiamine. Patients with sepsis are frequently thiamine deficient. This deficiency can cause congestive heart failure, peripheral neuropathy, Wernicke encephalopathy and gastrointestinal beriberi concomitantly, because it results in energy deficit. This should alert emergency room physicians to such a possibility with COVID-19, particularly with the more severe symptoms.

The point that I am trying to make here is that our conventional approach to disease may be catastrophically wrong. The symptoms, particularly those that are obviously related to brain function, arising from COVID 19 may be just expressions of a defensive war where failure spells death and recovery spells victory. The potential involvement with thiamine metabolism strongly suggests energy deficit as the underlying mechanism and that treatment should be aimed at “supporting the defense” by providing its stimulation instead of trying to find a means of killing the virus.

Drug Related Thiamine Deficiency

Drug-nutrient interactions have the potential to cause serious adverse events but unfortunately they receive little attention during drug development. Their importance was highlighted when the clinical trial of a drug had to be terminated because it was found that it interfered with thiamine absorption. The authors screened 1360 compounds, including many clinically used drugs and identified 146 that had this inhibitory reaction. The antibiotic metronidazole (Flagyl) is converted to a thiamine analog (a nearly identical formula), with consequent vitamin B1 antagonism, thus explaining how “toxicity” is produced by this drug. Serum thiamine levels were significantly lower in a group of patients with neurological symptoms receiving chemotherapy for gastrointestinal cancer. Perhaps the use of pharmacotherapy is another example of a fundamentally inappropriate treatment of symptoms without addressing the real issue.

We are beginning to understand that the organizational capacity of the brain in setting up a defense against a lethal microorganism requires an enormous amount of energy. Perhaps it is the present preoccupation with finding a name for a disease, based on its locality in the body that diverts our attention. A good example was published some years ago in Japan. Since the early 1960s a peculiar neurological disease became prevalent throughout Japan. It went by the name of subacute myelo-optico-neuropathy (SMON), later to be found due to the prescription of a drug called clioquinol for diarrhea. Apparently the cause of the disease had been ascribed to a virus as early as 1978. It should be apparent that discussing differences in the cause of disease would not matter nearly as much if a nutraceutical approach to treatment were to be adopted. The concept is reinforced by the information on television that 70% of COVID deaths occur in the black community where poverty and malnurition tend to go hand in hand. It would explain the reason why some people have only mild symptoms while others succumb, why concomitant disease and aging are risk factors. Could it be that all disease is just a temporary lack of ATP (sometimes referred to as the energy currency) arising from nutritional error, coupled with genetic risk: that nutraceuticals are the ubiquitous treatment for all?

What Can Selye Tell Us About COVID-19? Survival Requires Energy

Host Defenses

Most people are aware that Louis Pasteur played a major part in the discovery of microorganisms, particularly those that affect our health. He is purported to have said on his deathbed “I was wrong: it is the terrain that matters”. He meant, of course, the natural defenses with which the human body is equipped. In fact, he was stating something that is simple to understand. All members of the animal kingdom, including humans, live in a hostile environment, the major contributor to which are the microorganisms that result in disease. I like to think of them as “the enemy” that represents a war-like attack that tests our naturally endowed defensive mechanisms. The paradigm in medicine that exists at present is quite simple, “kill the enemy”. What Louis Pasteur was saying applied to the idea that the attack by the enemy is automatically met by a complex of defenses. Each attack by the microorganism can be viewed as much like a war. The question is, what we can do to make sure that the defenses are as vigorous as Mother Nature intended them to be. In order to answer that question, I turn to the work of Hans Selye.

Selye and Stress

As I have mentioned in previous posts on this website, Selye was a medical student in Hungary. One thing that professors of medicine do for students is to present them with patients suffering from the various diseases with which they have been diagnosed. Well, Selye was not listening to the professor. He was observing the facial expression of each of the patients as they were presented. He came to the conclusion that they all looked very much the same, that it was a response to the stress imposed by the illness from which they were suffering.

After graduation, he immigrated to Canada and set up an Institute in Montréal with a specific intention to study the effects of stress. Selye defined “stress” as anything that attacked the status quo of an animal. It included infection and trauma. In the modern world, stress is considered as purely a mental phenomenon. That is incorrect. Stress is anything that requires physiological energy to resolve. It can come in the form of mental or life stress, but the energetic demands remain the same as if it were the stress of an illness.

Selye set out to try to discover its mechanisms. His studies were performed on thousands of rats which he injured in various ways. He concluded that if the animal was fit, it would adapt to or resist whatever stress was imposed. If it failed to adapt, or if the stress was overwhelming (for humans, as in a car accident), the animal would die. He explained this under the heading of what he called the General Adaptation Syndrome (GAS). He found that the various laboratory studies on the blood and tissues of the injured animals exactly replicated the information obtained from laboratory studies done on humans suffering from illness. He called human diseases “the diseases of adaptation”.

One of his remarkable conclusions was that this adaptation through the GAS required huge amounts of energy, although at that time, little was known about how this energy was generated. However, one of his students knew that vitamin B1 (thiamine) was an important part of energy generation and he was able to show that deficiency of this vitamin resulted in a replication of the GAS, without traumatizing the animal. We can conclude that a severe lack of thiamine might be the cause of what we call “shock” and a complete lack would be lethal. Today we have detailed knowledge concerning the role played by thiamine in the generation of cellular energy and this particularly applies to the part of the brain that organizes and controls our adaptive ability through the autonomic and endocrine systems. We know that the immune system is controlled by the automatic brain and a deficiency of the required energy surge would encourage a successful attack by the “enemy”.

COVID-19 and Other Viral Pandemics

In the case of the current viral pandemic, the coronavirus – COVID-19, infection and trauma are considered as the “enemy” requiring an energy dependent defensive reaction organized and controlled by the brain. Does Selye’s work apply to COVID-19 or any other viral pandemic? The answer to that question, based on convincing evidence, is that it does indeed apply. A recent discovery is that a combination of hydrocortisone, ascorbic acid and thiamine (HAT therapy) given intravenously, is a successful treatment for sepsis, a condition that is almost uniformly lethal. This is clearly an assistance in supporting the defensive mechanisms by damping down the associated inflammation and regulating oxidative metabolism in the production of energy. Recently, thiamine has been found to be useful in the treatment of people with chronic disease, strongly suggesting that defective energy metabolism is an important part of the pathology. It has been reported that in-patients, being treated for psychiatric symptoms, are at risk for developing the serious symptoms of a brain disease known as Wernicke Encephalopathy, well known to be due to thiamine deficiency. Finally, a report from the Department of Infectious Diseases, Wenzhous Central Hospital, Zhejiang Province, China describes the symptoms of the patients with COVID-19 treated in that hospital. One of the major findings was hypokalemia (low concentration of potassium in the blood). Nausea and vomiting were described in some of the patients. There are pumps in the cell membrane that pump potassium into the cell and sodium out of it. These pumps are energy dependent and are inherently vital to the function and life of all cells in the body. It is failure in this pump mechanism that is responsible for a low potassium and that is why hypokalemia occurs in the vitamin B1 deficiency disease beriberi, perhaps the best known condition primarily associated with energy failure. Nausea and vomiting, perhaps nonspecific as they are, also occur in beriberi.

It is proposed here that stimulating energy metabolism might improve the defensive action organized and conducted by the brain, obeying the dictum suggested by Louis Pasteur. It assumes of course that the genetics of the patient decide the intricacies of the defense program, but the relatively new science of epigenetics shows that energy, derived from nutrition, can improve genetic status. We believe that we have shown evidence that thiamine and magnesium supplementation are inherently necessary in a population in which nutrition is imperfect. In light of the success using thiamine and vitamin C in sepsis, one of the many negative outcomes of COVID-19, might a similar approach be employed in the treatment here. Moreover, if we consider the requisite ‘energy’ required to stave off any illness, might we also consider bolstering the nutrient stores e.g. host defense in at-risk populations, as a way to reduce the risk and severity of the illness? Doing so may help ensure the adequacy of energy in meeting the unseen enemy.
