How the Immune System affects Parkinson’s Disease

By Ray Schilling | autoimmune disease, diet, Fitness, immune system, Inflammation, Parkinson’s disease

T cells that react to a damaged protein called alpha-synuclein

There are specific changes in the immune system approximately 10 years before Parkinson’s disease symptoms occur in patients who come down with the disease. Researchers from the La Jolla Institute for Immunology showed that T cells play a key role in causing PD. They react to a damaged protein called alpha-synuclein build up in the dopamine-producing brain cells. Laboratory physicians can assay this through a simple blood test, which becomes a screening tool for early Parkinson’s disease. The reactive T cells stay around for about 10 years, then fade away. There seem to be other immune factors that weaken the initial aggressive phase of the T cells.

The role of inflammation in Parkinson’s

When the immune system malfunctions chronic inflammation can develop. In farmers exposed to pesticides the later development of Parkinson’s disease was observed. The researchers thought that the pesticides caused an irritation of the immune system leading to chronic inflammation. There is evidence that the gut bacteria are different in Parkinson’s disease patients when compared to normal controls. The gut absorbs the metabolites of the abnormal gut bacteria and causes chronic inflammation. In an attempt to stop the inflammatory process, the immune system can develop autoimmune antibodies, which can cross react with cells of the substantia nigra. This in turn can cause Parkinson’s disease.

Lifestyle factors that people can change to prevent PD

Dr. Rebecca Gilbert, vice-president and chief scientific officer for the American Parkinson Disease Association (APDA) commented on the importance of lifestyle changes. She said: “It makes intuitive sense that instituting lifestyle modifications that potentially decrease inflammation may decrease the risk of Parkinson’s disease. Exercise, for example, has been shown to reduce inflammation and is probably one of the many reasons that exercise reduces the risk of Parkinson’s disease and also improves established Parkinson’s disease.” She commented further: “Also, we should avoid things like excessive alcohol and nicotine that we know have negative effects on the immune system,” she added. “And managing our stress as best as possible can slow and help maximize outcomes of many diseases.”

Changing diet can help postpone Parkinson’s disease

With regard to the best diet that will help Parkinson’s disease patients she said: “The MIND diet emphasizes whole grains, vegetables, nuts, legumes, and berries. Fish is the preferred protein and olive oil is the preferred fat. Recently a study showed that adherence to the MIND diet and the Mediterranean diet had an association with later onset of Parkinson’s disease.”

The gut connection to Parkinson’s disease

According to the WHO the global prevalence of Parkinson’s disease has doubled in the last 25 years. At this point we do not know why this is so. But many investigations have shown that there is a significant difference in the gut bacteria composition of healthy controls and Parkinson’s disease patients. There is a 30% difference between the bacterial composition of healthy controls and patients with Parkinson’s disease. This has led to Braak’s Hypothesis of Parkinson’s Disease. This hypothesis says that an unknown pathogen enters through the nose, the person swallows it and it ends up in the gut. Absorption gets it into the gut wall and it migrates through the vagus nerve into the central nervous system where it leads to accumulation off alpha-synuclein in the substantia nigra. This destroys the dopamine producing cells in that region causing the symptoms of PD.

Can any diet fight gut dysbiosis?

In 2022 study they found that flavonoids, the pigments of fruit were associated with a lower mortality of patients with Parkinson’s disease.
In an earlier study of 2018 researchers determined that a protein from fish with the name parvalbumin helped Parkinson’s patients to stop producing alpha-synuclein. PD patients suffer from clumping of alpha-synuclein, which causes their symptoms.
Restriction of refined carbohydrates “especially diets with a low glycemic index, rich of vitamins and polyphenols, a Mediterranean diet for example, can be recommended”.

Regular exercise to prevent Parkinson’s disease

Regular physical exercise maintains body function and muscle strength. Dr. Emer MacSweeney said: “Being physically active is one of the best things you can do for your body. Exercise helps protect against many diseases and keeps the heart, muscles, bones, and brain in optimum condition. Exercise promotes the oxygenation of the brain and stimulation of multiple neurochemicals.”

Several studies showed that patients with PD deteriorate slower, if they exercise regularly. Part of that response is due to the release of endorphins and serotonin, but we do not know all of the positive mechanisms of exercise at this time.

How the Immune System affects Parkinson’s Disease

Conclusion

Recent research changed what we know about Parkinson’s disease (PD). Braak’s Hypothesis of Parkinson’s Disease states that an unknown pathogen enters through the nose, gets swallowed and ends up in the gut. From there it gets taken up into the gut wall and migrates through the vagus nerve into the central nervous system. There it leads to accumulation of alpha-synuclein in the substantia nigra. This destroys the dopamine producing cells in that region causing the symptoms of PD. But we also know that chronic inflammation can aggravate the symptoms of PD patients. When the composition of the gut bacteria deteriorates, this too will make PD patients worse.

Lifestyle changes help to postpone Parkinson’s disease

A healthy diet, like the MIND diet, DASH diet or the Mediterranean diet have beneficial effects on PD patients. Many studies also found that regular physical exercise is a stabilizing factor in PD patients. There are still many gaps in what we know about the causation of PD. But the above summarized factors are a good start.

Cortisol is the Number 1 Longevity Hormone

By Ray Schilling | Cardiovascular disease, Hormones, immune system, Stroke

At the 30^th American Anti-Aging Academy Medicine Conference in Las Vegas one topic was that cortisol is the number 1 longevity hormone. Dr. Thierry Hertoghe, an endocrinologist from Brussels, Belgium gave a comprehensive lecture on Saturday, Dec.10, 2022. He explained that cortisol from our adrenal glands is vital to our health. Certainly, it is important for our quality of life and for health in general. Indeed, cortisol keeps us alive when various circumstances challenge our health. Specifically, cortisol is on the bottom of the hormone cascade of corticotropin releasing hormone (CRH) from the hypothalamus/ Adrenocorticotropic hormone (ACTH) from the pituitary gland/and cortisol from the adrenal glands. It is important to realize that this is the hormone axis of the stress reaction that Dr. Selye first described.

Production of cortisol

Sedentary men produce 30 mg of cortisol per day, women 20 mg/day. Under stressful conditions ACTH production increases and causes an increase of cortisol production in the adrenal glands. To clarify, stressed men produce 40 to 60 mg per day and stressed women produce 30 to 40 mg/day. In addition, the older a person is, mononuclear leukocytes have less type 1 and type 2 glucocorticosteroid receptors.

Action of cortisol

Dr. Hertoghe pointed out that cortisol increases energy and stress resistance. It causes blood sugars to increase and also elevates blood pressure. The immune system gets stronger, allergies and inflammation decrease. Cortisol shapes our bodies: when there is cortisol deficiency the body is thin; with normal cortisol production the body has a normal configuration. Your body develops swelling and obesity with cortisol excess, but when cortisol is missing the body gets frail and thin.

Cortisol deficiency

Low cortisol production leads to low blood sugar and low blood pressure. This diminishes glycogen stores in the liver and muscle mass. A lack of circulating cortisol reduces gluconeogenesis in the liver, which is an alternative pathway of glucose production. One of the hallmark symptoms is mental fatigue, particularly in times of stress. With cortisol deficiency the person feels fatigue in the second part of the day.

Chronic fatigue syndrome

The peak age for chronic fatigue syndrome patients is 31 years. The mean duration of the illness lasts 7 years. 58% of patients have free serum cortisol levels at 20:00 hours, which is less than normal. In 40% of patients the total cortisol level is less than normal.

Burnout

With burnout the urinary free cortisol is diminished. Patients with cortisol deficiency have a hyper sensitivity to stress.

A lack of cortisol leads to feeling no energy and having no stress resistance. The person feels tense and has negative thinking. A person who has sufficient cortisol is full of energy, expresses emotions and handles stress well. With enough cortisol a person is relaxed, has positive feelings and finds solutions everywhere.

Adrenal crisis

Dr. Hertoghe explained that an adrenal crisis happens when there is not enough cortisol production in the adrenal glands to support the metabolism and the cardiovascular system. Gastrointestinal diseases, infectious diseases or stressful events like surgery, exposure to heat, strenuous physical activity, major pain or pregnancy can all trigger an adrenal crisis. When glucocorticoid therapy is withdrawn, this can also cause an adrenal crisis.

Addison’s disease

With Addison’s disease there is a lack of energy, muscle weakness, loss of appetite and unintentional weight loss. The reason for the symptoms is that the adrenal glands are not producing enough cortisol and aldosterone. There was a more than 2-fold increased risk of dying from Addison’s disease compared to a normal population in a Swedish study.

In another study the serum cortisol levels were determined in patients with heart attacks. The ones who had extremely low levels of cortisol were at almost a 9-fold risk of dying within 30 days compared to patients with a normal serum cortisol level. One of the famous patients with Addison’s disease was J.F. Kennedy. He collapsed in London, England and was finally diagnosed correctly in a British hospital after having suffered for several years without the correct diagnosis. This disease is not always easily diagnosed.

Cortisol therapy

With an adrenal crisis or Addison’s disease cortisol therapy can be life-saving. The physician uses physiological doses of glucocorticosteroid hormones (cortisol and others) and in emergency situations higher than normal doses. Dr. Hertoghe said that survival data were gathered with various severe disease conditions as follows.

Coronary heart disease survival

Dr. Hertoghe reported about a study that observed 1090 adults over 11 years. There was a 40% reduction of mortality when patients were treated with cortisol following a heart attack compared to controls who did not get cortisol treatments. The researchers also found that there was a 39% lower stroke risk when treatment with cortisol was instituted.

In a clinical trial with 39 patients who had heart attacks those patients treated with pharmacological doses of methylprednisolone (3 grams daily) experienced a significant reduction in infarction size.

In another study with 1118 patients Dr. Hertoghe reported a 28% reduction in mortality over 28 days compared with a placebo group. In this study medical researchers gave 2-3 grams of methylprednisolone early on into the heart attack. In the same study, after 6 months there was a 33% mortality reduction.

Stroke survival

Following a stroke, low cortisol levels (270 nmol/L) and high cortisol levels (550 nmol/L) both had an association with a poor long-term prognosis 1 year after follow-up. However, the study also showed that patients with normal cortisol levels (between 270 nmol/L and 550 nmol/L) following a stroke had a very good long-term prognosis.

AIDS survival

AIDS patients belong into the group of chronic diseases that are associated with low cortisol levels in the blood. There are also clinical signs of low cortisol, namely dark circles around the eyes, hollow cheeks, brownish pale skin with pigment spots, hand creases that are pigmented and weight loss. Severely ill AIDS patients often have severe lung infections (Pneumocystis carinii pneumonia) due to their immune deficiency. A study involving 23 AIDS patients used methylprednisolone in the treatment group and no methylprednisolone in the placebo group. The clinicians administered 40 mg of methylprednisolone every 6 hours for 7 days in addition to antibiotic treatment for 3 weeks. They compared this to the placebo group without methylprednisolone. 75% of the treatment group survived until the hospital discharge compared to only 18% of the placebo group.

Sepsis and septic shock

Treatment of patients with septic shock with ACTH (the stress hormone) infusions showed that 88% had a cortisol response among survivors. The ultimate non-survivors only had a 27% cortisol response of their adrenal glands when stimulated by intravenous ACTH. Dr. Hertoghe pointed out that this suggests that some patients with septic shock may have relative adrenocortical insufficiency. This would explain why the adrenal glands of septic shock patients can be non-responsive to ACTH. In these cases, it is important that the physician treat with either intravenous cortisol or with synthetic glucocorticoids.

Treating septic shock with intravenous hydro-cortisol

One study showed that treating septic shock with intravenous hydro-cortisol gave the following results compared to placebo:

7- fold higher septic shock resolution when compared to the placebo group
8 – fold survival in the intensive care unit
2 – fold higher hospital survival
2 – fold better septic shock reversal in 7 days
8 – fold better survival in the next 28 days.

Overall, this study clearly revealed that septic shock recovery is much better with intravenous hydro-cortisol treatment.

Cancer survival

A study found that breast cancer patients with metastases had flat saliva cortisol curves when compared to patients without breast cancer. If left alone breast cancer patients with a flat cortisol curve die earlier than those who used cortisol supplementation. The researchers found out that the natural killer cells (NK cells) in these patients were missing. These are special lymphocytes that can kill cancer cells with their enzyme vesicles.

Glucocorticoid treatment

Dr. Hertoghe talked about short-term high-dosed glucocorticoid therapy and the difference between synthetic cortisol equivalents (Dexamethasone etc.) and the natural cortisol. He also talked about adding small amounts of these hormones: DHEA, fludrocortisone (0.1 mg daily orally), and bioidentical vasopressin to optimize cortisol replacement.

Cortisol is the Number 1 Longevity Hormone

Conclusion

One of the vital hormones in our bodies is cortisol, the stress hormone. There is a hormone cascade starting with CRH in the hypothalamus, which stimulates ACTH release from the pituitary gland. This in turn releases cortisol from the adrenal glands. The end product, cortisol is the number 1 longevity hormone. It helps us to survive any stressful event. It gives us energy, stimulates the immune system and helps us to overcome dangerous illnesses. Dr. Hertoghe, an endocrinologist from Belgium gave a detailed lecture at the 30^th American Anti-Aging Academy Medicine Conference in Las Vegas on Dec. 10, 2022. Dr. Hertoghe discussed how to survive a heart attack or stroke, sepsis, AIDS or Addison’s disease (=adrenal gland insufficiency) by adding appropriate cortisol doses or equivalent synthetic glucocorticosteroids. One thing is clear: we all need cortisol until the end of our lives.

Mast Cell Activation Syndrome

By Ray Schilling | alcohol, Allergies, anaphylactic reaction, diet, immune system, Inflammation

Mast cell activation syndrome (MCAS) also goes by the name of systemic macrocytosis. That is to say it is a syndrome where mast cells are multiplying abundantly and secreting the inflammatory substances histamine, leukotrienes and cytokines. Certainly, people who suffer from MCAS can get severe anaphylactic reactions, but an epinephrine injection can often stop this. Indeed, the physician must look for potential triggering factors like alcohol, spicy foods, exercise, insect stings, possible heavy metal accumulation or certain medications. In some cases heavy metal accumulation could also be a factor that triggers mast cells to release histamine. In these cases a series of 20 chelation therapy sessions would be stabilizing.

Symptoms of mast cell activation syndrome

When there is skin involvement in patients with mast cell activation syndrome, they get flushing, itching and skin rashes.
With gastrointestinal involvement patients experience nausea and vomiting, bloating, abdominal pain, diarrhea and reflux (GERD).
Patients with neurological symptoms develop brain fog, headaches, cognitive problems, tremors and anxiety/depression.
When MCAS affects your endocrine glands, you may develop bone pain, bone lesions or weak bones.
Patients where the heart is affected may be fainting, their blood pressure may fluctuate between with high or low readings and they may experience heart palpitations.
When your respiratory system is affected, your lungs may be wheezing and you may develop nasal congestion.
More symptoms
The most dangerous symptom is anaphylaxis. This is a life-threatening allergic reaction where your air way entry could close off.
Any of these symptoms can get triggered by heat, cold or temperature changes. Stress, friction, insect bites or stings can also trigger a reaction. Additional factors can be environmental odors or perfumes, certain foods or medicine, alcohol and contrast dyes.

Diagnosis of mast cell activation syndrome

The most appropriate specialist to see is an allergist or immunologist. Other specialists could be a dermatologist, gastroenterologist, hematologist or endocrinologist. You will need blood tests like a serum tryptase level, which is a marker for mast cell burden. It is best to get a baseline tryptase level and also get a tryptase level after a mast cell reaction. In addition, you need a 24-hour urine collection for a number of mast cell activators. Depending on where your mast cell activation syndrome is located you need a skin or bone marrow biopsy.

More possible tests

The physician may decide to do an endoscopy or colonoscopy of the gastrointestinal tract. The pathologist can do several staining procedures with biopsy material to specifically look at mast cells. If there is a strong family history of mast cell activation syndrome the physician may decide to do genetic tests. In order to assess mast cell damage, your doctor may order a bone density test and bone scans including CT scans of the abdomen and chest.

Treatment of mast cell activation syndrome

The treatment of mast cell activation syndrome consists of a combination of multiple steps. First, if there is a life-threatening anaphylactic reaction, the patient applies an epinephrine injection. The physician taught the patient earlier how to do an epinephrine injection. This stops the sudden, rapid release of mediators from mast cells. After the epinephrine injection the patient needs transport to the nearest ER of a hospital for follow-up care. It is important that any patient with this syndrome should carry injectable epinephrine( an Epi-Pen) at all times.The purpose of treatment against mast cell activation syndrome is to block reactivity of mast cells or to stop the effects of mast cell mediators.

A number of medications are available to do this.

H1 and H2 antihistamines. The difference between these two is explained here.
Mast cell stabilizers (cromolyn sodium, ketotifen). For more on ketotifen follow this link.
Leukotriene inhibitors such as montelukast. You can find more info on leukotriene modifiers here.
Aspirin (under direct physician’s supervision)
Aggressive mast cell disease may require treatment with chemotherapy.

You can lower your risk of getting mast cell activation syndrome by watching your diet. Here is a list of the foods that will protect you:

Mast Cell Activation Syndrome

Conclusion

Mast cell activation syndrome is a complex disease entity. Often there are several factors that contribute to this. Conventional medicine still cannot offer a treatment modality that will cure this condition, the only possibility is to control it. The physician must therefore use a combination of treatment modalities in order to help the patient with this condition. In cases of heavy metal accumulation several treatments with chelation therapy are beneficial. With an acute anaphylactic reaction, the

Mast Cell Activation Syndrome applies an epinephrine injection, which will stabilize the condition. But the patient should now follow this up with a series of blood tests in the emergency department of a hospital.

Treating mast cell hyperactivity

The purpose of treating mast cell activation syndrome is to block reactivity of mast cells or to stop the effects of mast cell mediators. H1 and H2 antihistamines help for gastrointestinal hyperactivity. Cromolyn sodium and ketotifen are mast cell stabilizers. Leukotriene inhibitors such as montelukast help to stabilize the mast cells to not secrete cytokines, which cause inflammation. Aggressive mast cell disease may require chemotherapy treatment, similar to what is needed to treat cancer.

The purpose of treatment is to help the patient control the mast cell hyperactivity. At this time medical science does not have all the answers. Unfortunately, at this point conventional medicine has no cure for this syndrome, but it can be managed with a lot of attention to the symptoms.

New Immunotherapy Approach against Cancer

By Ray Schilling | Cancer, immune system

A recent publication reported about a new immunotherapy approach against cancer. The model it dealt with was a very vicious brain cancer with the name glioblastoma. The results of this research were subsequently transferred to another vicious cancer, osteosarcoma, which is a form of bone cancer with a very poor prognosis. Researchers have to do further clinical experiments to establish this new immunotherapy in osteosarcoma patients. Physicians completed the following experiments and clinical studies.

Oncolytic virus Delta-24-RGD can lead to remission in glioblastoma patients

Researchers at the University of Navarra, Pamplona, Spain together with The University of Texas MD Anderson Cancer Center in the US investigated glioblastoma patients. They found that treatment of glioblastoma patients with oncolytic viruses Delta-24-RGD led to a greater than 3-year remission in 20% of cases. Normally, patients with a glioblastoma survive only 9 months on average. 12% had a greater than 95% reduction in the size of the tumor. This was a phase 1 clinical study with 37 patients who had recurrent malignant glioblastoma. The authors said: “Oncolytic adenoviruses are attractive therapeutic agents because they can kill tumor stem cells and induce cell death by several mechanisms, including direct lysis, expression of toxic proteins, induction of cytokines, and T-cell–mediated immunity.” The particular oncogenic virus that the researchers used was an adenovirus Delta-24-RGD.

Transferring glioblastoma results to a cure for osteosarcoma

The same researchers wanted to see whether the cure rates of treating patients with glioblastoma was transferable to other cancer patients. In particular they were interested in patients with osteosarcoma, which is a similarly vicious cancer. Advanced osteosarcoma has a survival rate of 27% after 5 years. The researchers first did experiments with a human osteosarcoma cell line in tissue culture and at the same time a murine osteosarcoma cell line. Later they tested the action of oncolytic viruses Delta-24-RGD in a mouse model.

Experiments with osteosarcoma cells in tissue culture

The advantage of such experiments is that you can control all the parameters easily in a Petri dish. But critics say that this is far removed from osteosarcoma behavior in humans. Researchers found that the oncolytic virus Delta-24-RGD killed many osteosarcoma cells in vitro. They also were able to insert a new gene into the oncolytic virus, which was equally effective in killing osteosarcoma cells. They called this virus Delta-24-ACT.

Curing osteosarcoma in a mouse model

Next the researchers tested effectiveness of the oncolytic viruses, Delta-24-ACT and Delta-24-RDG in mice. They injected osteosarcoma cells from tissue culture into the tibia of mice. Tumor growth was subsequently measured. The experimental groups were given two oncolytic virus infections, the control group did not. On day 10 and 18 the researchers could see that controls had faster growing tumors compared to the experimental groups. The experimental groups had less tumor side effects. And the experimental mice survived longer than the controls. Further research showed that the oncolytic viruses produced a 4-1BBL protein, which stimulated the animals’ immune system to fight the osteosarcoma.

New immunotherapy approach against cancer: Effector T cells

Researchers could prove that in mice treated with oncolytic viruses it was the special protein (4-1BBL) that stimulated T lymphocytes to become killer T cells. They in turn attacked the osteosarcoma cells.

New immunotherapy approach against cancer: The need for human research

Doing research in humans is more complicated than in a mouse model. But in order to improve survival rates in patients with osteosarcoma human research is absolutely essential. However, research is complex and the effects of oncolytic viruses is only in the 20% range with regard to increasing survival. This requires more research. It may be that instead of oncolytic viruses a stimulatory protein would arm T cells to become killer T cells that fight the cancer.

New Immunotherapy Approach against Cancer

Conclusion

Glioblastoma patients had a better survival after treatment with oncolytic viruses Delta-24-RGD. Researchers translated this type of research to another cancer, osteosarcoma. This also has a poor prognosis, Researchers did experiments in tissue culture and in a mouse model. They were able to show that oncolytic viruses produced a 4-1BBL protein, which stimulated the animals’ immune system to fight the osteosarcoma. Specifically, the protein armed T lymphocytes and turned them into killer T lymphocytes. These destroyed osteosarcoma cells in tissue culture or in the mouse model. It is encouraging to see positive results in a laboratory setting of a tissue culture. The step further in an animal experiment is also a positive achievement. More research will improve the cure rates of osteosarcoma. The effective treatment of osteosarcoma in humans is still far away! The next step is human research that shows improvements in patients’ survival rates.

Tick Bites Can Render You Allergic to Red Meat

By Ray Schilling | Allergies, anaphylactic reaction, immune system, red meat

Tick bites can render you allergic to red meat. This comes from the alpha-gal syndrome, which is a type of food allergy. It is a tick with the name of Lone Star tick that transmits this syndrome in the southeastern United States.

Deer carries the Lone Star tick into other parts of the US. The bite of the tick transfers a sugar molecule called alpha-gal into the person’s body. Subsequently the person develops a sensitivity to red meat, like beef, pork and lamb. Red meat membranes are rich in the sugar alpha-gal. The allergy can also be directed against other mammal-related products like milk protein. Often the person is unaware of this type of allergy, alpha-gal syndrome. In this case people continue to get exposed to red meat and mammal products, and the immune reactions become more severe over time. Anaphylactic reactions that are not due to food allergies have a high probability to be due to alpha-gal syndrome.

More details about the alpha-gal syndrome

Alpha-gal is the abbreviation for Galactose-alpha-1,3-galactose, which is a carbohydrate. It is part of most mammalian cell membranes, except for primates. The immune system in humans recognizes it as a foreign body and produces anti-alpha-gal antibodies. It is the bite of the lone star tick in North America or the castor bean tick in Sweden that can start the allergy to alpha-gal. If a person has frequent anaphylactic reactions, the physician should think of alpha-gal syndrome, which could be the underlying cause.

Sensitization of the human host

When the lone star tick bites mice, rabbits or deer it takes up alpha-gal sugar. Subsequently, when the tick bites a human, the alpha-gal sugar is injected into the human host together with its saliva. This alarms the immune system and antibodies are produced. When the human host later consumes meals with red meat, the body reacts to the previous sensitization to alpha-gal sugar by the tick bite. The antibody response to alpha-gal sugar from further red meat meals becomes even stronger than before. The only relief for human host from immune reactions is to switch to a diet that is free of red meat.

Allergic symptoms

The alpha-gal allergy can manifest itself by skin rashes, welts, skin itchiness, swelling, shortness of breath, headaches, belly aches, diarrhea and vomiting. In serious cases an anaphylactic reaction can occur, which in some cases can be lethal.

Protein allergies versus carbohydrate allergies

Until 2009 medical science believed that allergies would only be due to proteins. One such example are allergic reactions to peanuts. It is the peanut protein that can cause allergies. Subsequently, the alpha-gal allergy became known, which involves the sugar galactose-alpha-1,3-galactose. This was the first sugar molecule that researchers could demonstrate to mount an allergic reaction, from which the human host could turn sick.

Tick Bites Can Render You Allergic to Red Meat

Conclusion

The Lone Star tick in the southeastern US carries the sugar galactose-alpha-1,3-galactose (for short alpha-gal) which originates from bites of mammals that are not primates (cattle, pigs and lambs). When the tick bites a human, the immune system produces antibodies against alpha-gal. This can produce skin rashes, welts, skin itchiness, swelling, shortness of breath, headaches, belly aches, diarrhea and vomiting. But when the person recovers from the tick bite, a lifelong sensitivity against reed meats remains. Every time a sensitized person consumes a red meat meal the same symptoms, as originally experienced from the tick bite, return.

Abstinence from red meat

The only remedy for the alpha-gal syndrome is to abstain from red meat. The cell membranes of the muscle of red meat contain the sugar alpha-gal. Seafood, chicken, eggs and turkey meats are OK for consumption. But the patient has to be diligent about not making any dietary mistakes. If intermittent red meat exposure continues, a more severe allergy can develop. These have the name of “anaphylactic reactions”, where the patient is in danger of suffocating or even die from it.

Immune System Responses against Covid-19 or anti-Covid Vaccination

By Ray Schilling | immune system, Infectious Disease, Prevention, vaccinations

This article is about immune responses against Covid-19 or anti-Covid vaccination.

Investigations of the immune system showed that people who had Covid-19 and subsequently were vaccinated had an immune response that lasted for at least one year. In the following a discussion follows about the details why this is so.

The WHO confirmed more than 430 million cases of Covid-19 since the pandemic started. 4.9 billion people or 63.9% of the world population received at least one vaccination as of late February 2022.

How vaccination against Covid-19 works

The vaccine attacks the spike protein of the Covid-19 virus (SARS-CoV-2). The body produces antibodies through B cell activation. These are lymphocytes that originated from the bone marrow (hence B cells). They are capable of producing large amounts of antibodies that target the spike protein of the virus. It takes at least two vaccinations with the Pfizer vaccine to get a good antibody response. A booster vaccine brings the antibody titer even higher.

Cell-mediated response by killer T cells

When the virus enters a cell, the antibodies are no longer effective. Here the T killer cell comes into play. T killer cells are lymphocytes that were thymus processed (hence the name T cells) and activated by the vaccine. T killer cells function as a second line of defence. These immune cells specialize in detecting virus-infected cells. They immediately destroy these cells before the virus has a chance to replicate and shed more virus copies into the blood stream. It is the T cell response that prevents hospitalizations and deaths. Media coverage misled the public to believe that the bulk of the immune response would be from antibody production. However, the truth is that the T cell response is what is responsible for recognizing Covid-19 variants and why people survive Covid-19 with very little complications.

Long term immunity

When people had a Covid-19 infection the activated B cells that produced antibodies and the T killer cells get converted into memory cells. With a re-infection the memory cells can reactivate themselves to turn again into active B cells producing antibodies and T killer cells. The key for immunity with multiple vaccinations is also the memory cell pool. Those with two Pfizer vaccinations and a booster vaccine are much more immune to Covid-19 than those who only received one or two vaccinations.

Waning immunity

Following an infection with Covid-19 the immunity comes to a peak at 3 months after the start of the infection. The CDC said that people who are 90 days post-infection do not require a quarantine when they meet someone with an active Covid infection. By about 6 months immunity is declining. This is also true for people after double vaccination and a booster vaccine.

Hybrid immunity

The immune response after either a natural infection with Covid or following vaccinations with anti-Covid vaccines lasts only about 6 months. On the other hand, scientists observed that people recovering from Covid infections who subsequently received an anti-Covid vaccine just once had a very strong immune response that lasts for over a year. This is called hybrid immunity. This type of immune response triggers a very strong antibody response that is lasting longer. Immunologists are now researching whether the hybrid immunity is achievable with an improvement to vaccines. Results of this will not be available for several years.

Immune System Responses against Covid-19 or anti-Covid Vaccination

Conclusion

The immune response to Covid lasts for about 6 months; the same is true for the immune response after a vaccination. But when a person comes down with Covid and he or she receives a vaccination one month later, the immune response lasts for over one year. Scientists call this hybrid immunity. At this point experts recommend to have a booster vaccine every 6 months. But immunologists are researching for ways to incorporate the mechanisms of hybrid immunity into vaccines, which likely will not be available for several years.

Avoid deliberate exposure to Covid-19

Some persons who read about the response after a Covid infection and a vaccination misinterpreted this. They took this as an “invitation” to expose themselves to the virus in the hope to boost their immunity. However, a Covid infection remains an illness with potentially serious consequences. There is no way to predict whether the course of an infection will be mild or extremely severe. In addition, a significant number of patients come down with “long covid” and struggle with breathing problems, lack of energy and more. Covid is still here, and our best protection remains the full vaccination including boosters and hygienic measures. This involves masks, frequent hand-washing and disinfection of surfaces in daily life.

T-Cell Immunotherapy Cures Chronic Lymphocytic Leukemia

By Ray Schilling | Cancer, genetic marker, immune system, leukemia

T-cell immunotherapy cures chronic lymphocytic leukemia after 10 years. Researchers were able to use the blood of leukemia patients and modify immune cells to attack their cancer cells. Specifically, they introduced a chimeric antigen receptor into immune cells from patients in the lab. Subsequently they transfused the modified immune cells back into the leukemia patients. After 10 years researchers detected the same active cytotoxic T lymphocytes in both chronic lymphocytic leukemia patients, which contained the chimeric antigen receptor marker. This means that active cytotoxic lymphocytes, that also have the name of killer T cells, continued to eliminate any pathological cells from the lymphocytic leukemia patients.

The immune system explained

The immune system can respond with two major responses. The B lymphocytes originate from the bone marrow and turn into antibody producing plasma cells. With viruses this system works very well as it inactivates viruses that the immune system recognizes don’t belong into the body. The other branch of the immune system are the thymus-processed T cells. These are important to eradicate cancer cells. They are also called CD4 cells or cytotoxic T lymphocytes. Often tumor cells produce specific proteins that suppress the immune cells. But the researchers of these two chronic lymphocytic leukemia patients managed to introduce a chimeric antigen receptor into the CD4 cells that specifically targeted the leukemia cells. The immune system in these patients was working optimally and remained active for 10 years.

Some statistics regarding chronic lymphocytic leukemia

Here are some statistics of chronic lymphocytic leukemia (CLL). There were about 61,090 new cases of leukemia and 23,660 deaths from leukemia in 2021 in the US. Among these were 21,250 new cases of chronic lymphocytic leukemia (CLL). There were about 4,320 deaths from CLL. The average lifetime risk of getting CLL is 1 in 175 people or 0.5% of the population. The risk of getting CLL is slightly higher for men than women. CLL is a leukemia of older people, the average age at the time of diagnosis is 70 years. CLL is rare under the age of 40 and extremely rare in children.

Potential serious side effects of T-cell immunotherapy

Dr. David Porter, one of the authors of the study published in Nature said that this type of immunotherapy can have serious side effects. He added that therapies have become safer over the years. Oncologists are giving immunotherapies like the one which I described to hundreds and thousands of patients.

Here are the more common side effects.

The tumor lysis syndrome: when the tumor cells are all attacked at the same time, there is a lot of tumor cell destruction and the contents of the cells end up in the blood. This makes the patient rather sick for a few days. There can be serious electrolyte abnormalities that have to be countered with intravenous fluids. The toxins can also cause kidney damage, which physicians monitor closely.
Cytokine release syndrome: With this syndrome people develop a high fever, nausea, vomiting, much like a severe flu. They also develop muscle aches and joint pains. Patients can develop extremely low blood pressure. This occurs because fluid leaks into the lungs, which also causes problems breathing.
Neurologic toxicity: There can be a loss of speech and thought disturbances. Seizures can develop and the patients may turn comatose. Nevertheless most patients recover from this spontaneously.

Details of one case of CLL with successful treatment

Doug Olson was one of the patients who was studied in the publication in Nature. His original diagnosis was chronic lymphocytic leukemia when he was 49 years old. For 6 years he did not need much treatment. But then his leukemia flared up and chemotherapy got his CLL into remission for 5 years. Generally, leukemia behaves this way that treatment gets it into remission (meaning the leukemia is controlled). But on another occasion, it gets into a relapse, which means the leukemia flares up again. 11 years after the original diagnosis of the CLL there was a rapid decline due to another relapse. In a bone marrow biopsy 50% of the white blood cells were CLL and 50% were normal.

Infusion of CAR-T cells

He received his first infusion of CAR-T cells in September of 2010. Following this he became very sick and the oncologist hospitalized him for three days. One week later the oncologist could not find any more cancer cells in his body. But the cancer specialists were very reluctant to call it a cure at that time. Fast forward 10 years. And now there are still no cancer cells in Doug’s body. The blood analysis showed that active CAR-T cells are in Doug’s blood monitoring for him that no CLL cells reoccur. Now, 21 years after the initial diagnosis of his CLL the oncologists are convinced that the T-Cell Immunotherapy was what cured Doug.

Discussion

CLL is a special form of blood cancer. Chemotherapy has been successful in increasing survivor rates over the years. But the end of the patient with CLL comes from a final relapse of this leukemia form, which eventually no longer responds to chemotherapy. The researchers in this publication used a novel immunotherapy approach, where they introduced a chimeric antigen receptor into immune cells of patients in the lab. Subsequently they transfused this back into the leukemia patients.

T-cell Immunotherapy used surveillance T cells successfully

These modified immune cells became the “surveillance team” that eradicated new CLL cells and destroyed them on an ongoing basis. This immune therapy is getting rid of the last CLL tumor cell. The two cases described in this paper and investigated thoroughly after 10 years of immunotherapy intervention were completely free of CLL cells in their bone marrow biopsies. Two cases are not enough data, but it is a powerful result for a pilot study. Oncologists have to produce much larger clinical trials with more patients. This establishes that this new immunotherapy is superior to conventional chemotherapy and indeed prolongs survival compared to chemotherapy alone.

T-Cell Immunotherapy Cures Chronic Lymphocytic Leukemia

Conclusion

This pilot study showed that the immune system can be stimulated to suppress and eradicate leukemia (CLL) cancer cells. The authors introduced a chimeric antigen receptor into immune cells that were taken from patients. The researchers obtained blood samples. Then they introduced a chimeric antigen receptor into immune cells in the lab. Subsequently they injected these CAR-T cells back into the CLL patients. In these patients the CAR-T cells behaved like surveillance cells, which eradicated leukemia cancer cells on an ongoing basis. After 10 years of follow-up in two patients in this pilot study the clinicians could not find any CLL cancer cells in their bone marrows, but the CAR-T cells were still present. This type of study is encouraging as it is a model for immunotherapy of other cancers. It is a promising start, but obviously researchers need to do more studies to fine-tune cancer immunotherapy.

Stimulating the Immune System Leads to Better Cancer Survival

By Ray Schilling | immune system, Mortality, Nutrition, omega-3 fatty acids, Vitamins and supplements

Notably, conventional medicine has nothing to offer against advanced cancer, but stimulating the immune system leads to better cancer survival.

Dr. Hoffer’s survival experiment with incurable cancer patients

The following is a description of a 9-year follow-up of incurable cancer patients. They were given supplements known to stimulate the immune system and their survival rates were recorded. Ref. 1 describes the experiment by Dr. Hoffer, the father of orthomolecular medicine. It is important to realize that this is a branch of medicine that uses large doses of vitamins and minerals. This can rectify metabolic changes in various diseases. Dr. Hoffer treated 131 advanced cancer patients between 1976 and 1988 with a mixture of mega vitamins and minerals. There was a control group (not taking any supplements) and the experimental group.

Results regarding incurable cancer patients over 9 years

In fact, the results of this 9-year follow up study are depicted in the image below. The Y-axis represents the % of survival (at the zero point of time 100 % of each group were alive), the X-axis shows the time of survival in years. To clarify, the group of cancer patients taking meta vitamins is depicted with orange columns, the control group with blue columns. At 7 years of follow-up none of the controls survived. Explicitly, there was an 8-year survival advantage of the mega vitamin group versus the control group (control group 28% survival at year 1 of follow-up, mega vitamin group 34% survival at year 9 of follow-up).

List of supplements patients in the experimental group took daily

With this in mind, here is the detailed list of the supplements that Dr. Hoffer instructed his experimental group cancer patients to take daily.

Vitamin C, 10,000 to 40,000 mg orally daily; B3 vitamin (niacin or niacinamide) 300 to 3,000 mg; vitamin B6 (pyridoxine) 200 to 300 mg; folic acid 1 to 30 mg; vitamin E succinate 400 to 1,200 IU; Coenzyme Q10 300 to 600 mg; selenium 200 to 1,000 micrograms daily; zinc 25 to 100 mg; calcium and magnesium supplement (2:1 ratio); mixed carotenoids as carrot juice; multivitamins and minerals.

Ref. 1 (page 347) explains that in this case the Mayo Clinic did a study where they “duplicated” Dr. Hoffer’s study by using only high doses of vitamin C. It is important to realize that they failed to show any cancer fighting effect. However, they neglected to include all of the other cancer fighting supplements listed above. Vitamin C is an antioxidant that stimulates the immune system partially, but does not fight cancer by itself.

Strengthen your immune system by taking 14 supplements

In the following I like to share what I found when I investigated what supplements are necessary for optimal immune responses. The Linus Pauling Institute wrote a detailed review of the literature on the topic regarding “Immunity in depth”. It is published by the Oregon State University.

Essentially, there were 14 supplements that are listed below that were critical for the immune system to fully respond.

In the following I listed the 14 supplements, but, if they were present in Dr. Hoffer’s clinical cancer trial, I inserted them right after each item. 8 out of 14 supplements overlapped between Dr. Hoffer’s supplements and the supplements necessary to stimulate the immune system. There is a total overlap of 57%.

Vitamin A: mixed carotenoids as carrot juice
Vitamin B6: vitamin B6 (pyridoxine) 200 to 300 mg
B12 vitamin
Folic acid: folic acid 1 to 30 mg
Vitamin C: Vitamin C, 10,000 to 40,000 mg
D3 vitamin: Ray Schilling’s answer to Can vitamin D lower your risk of CoVID-19?
E vitamin: vitamin E succinate 400 to 1,200 IU
Iron
Copper
Selenium: selenium 200 to 1,000 micrograms daily
Magnesium: calcium and magnesium supplement (2:1 ratio)
Zinc: zinc 25 to 100 mg
Omega-3 fatty acids
Probiotics

Dr. Hoffer’s additional vitamins and minerals were: multivitamins and minerals; Coenzyme Q10 300 to 600 mg; and vitamin B3 (niacin or niacinamide) 300 to 3,000 mg. The 5 items that were missing in Dr. Hoffer’s clinical trial were vitamin B12, vitamin D3, iron, copper and probiotics.

Discussion

During the Covid epidemic the importance of the immune system for survival became very clear. One of the current mysteries regarding the immune system is why some people develop only very mild symptoms with Covid, while others get deadly sick. The other question has been around much longer: when it comes to cancer survival, why are there long-term survivors with some advanced cancers, but others perish. I believe that the key is how well the immune system is functioning. Dr. Hoffer’s end stage cancer survival trial achieved a 34% survival of cancer patients at year 9 of the clinical trial. At that time 100% of the control group were dead. Indeed, this is a remarkable finding.

Supplementation with vitamins and minerals prolonged cancer survival

The only difference was the supplementation with 57% of the Oregon University list of supplements necessary to stimulate the immune system. One of the more important supplements, namely vitamin D3 was not even included and yet there was a 34% survival in the experimental group after 9 years. Conventional medicine concentrates on surgery, radiotherapy and chemotherapy as the major therapeutic tools to fight cancer, but there is rarely if at all the mention of supplements. Ordinarily end stage cancer patients live on average 3 to 6 months.

Mayo Clinic’s attempt to jeopardize Dr. Hoffer’s cancer survival findings

When the Mayo Clinic got wind of Dr. Hoffer’s clinical trial they quickly attempted to “duplicate” the findings, but they left everything out except mega doses of vitamin C. Then they proclaimed that Dr. Hoffer’s data were flawed. In reality they failed to duplicate the findings, because they were poor copycats. Vitamin C is a powerful antioxidant, but it won’t be of help to cancer patients on its own. As the Oregon State University publication showed, there are 14 supplement that are necessary to work in symbiosis to stimulate to immune system to fight cancer.

It is significant that there was a 57% congruence between Dr. Hoffer’s list and the Oregon State University list of supplements to stimulate the immune system. Future cancer clinicians should revisit Dr. Hoffer’s clinical findings and finetune them to increase the long-term cancer survival times. For one, the supplement list should include vitamin D3, probiotics and omega-3 fatty acids.

Conclusion

Dr. Hoffer did a clinical trial that lasted 9 years between 1976 and 1988. Some patients were recruited earlier than others, but all were observed for a total of 9 years. He treated end-stage cancer patients with vitamin and mineral supplements. A control group that did not take any supplements was included in the trial. After 9 years the experimental mega vitamin group had a survival of 34%. None of the controls that did not take any supplements were still alive after 7 years. The literature by the Oregon University showed that 14 supplements are necessary to support the immune system. Dr. Hoffer’s clinical trial used 57% of these supplements. I am postulating that the good results of the mega vitamin group with respect to cancer survival likely comes from a strengthening of the immune system with the supplements.

The future of cancer treatments

Cancer treatments are entering a new phase where with the help of multiple treatment modalities combined (photodynamic therapy or PDT, immunostimulation, oxygen therapy and low-dose laser activated chemotherapy) it is now possible to cure many cancers that were untreatable in the past. The tunnel vision approach of conventional oncology with only a combination of surgery, chemotherapy and radiotherapy is obsolete for cases where cancer has metastasized. At this point the methods described here are promising, but have to be still considered experimental until larger clinical trials confirm Dr. Hoffer’s findings.

Booster Vaccinations Against Covid-19 Variants are Very Effective

By Ray Schilling | immune system, Infectious Disease, Mortality, vaccinations, Vitamins and supplements

This article will inform you that booster vaccinations against Covid-19 variants are very effective. Studies in patients from Israel who received a third vaccination (booster shot) showed much less omicron infections. Researchers compared the number of omicron infections in patients with only two shots and another group with three vaccinations (regular vaccination+booster shot). In patients who had booster shots infection rates were 10-fold lower.

Antibody titers matter

What seems to be happening is that antibody titers against Covid-19 rise after each vaccination providing more and more protection against the virus. Patients in this study had 90% less Covid-19 infections after a booster (=3 shots with the Pfizer vaccine) when compared to a double vaccinated group. Researchers compared nursing home residents who were previously sick with Covid-19 versus those who were not. They did PCR tests in April or June of 2020 to identify that there was a past history of Covid-19 infection with a subsequent recovery. Within 3 weeks after one dosage of an anti Covid-19 vaccine their antibody tests rose to above 40,000 arbitrary units (AU) per milliliter. The threshold was 50 AU to be positive.

The Israeli experience

An Israeli study was published on Nov. 5, 2021. Researcher determined the antibody titers in blood samples after anti-Covid-19 vaccinations. They investigated the antibody titers after two vaccinations and compared them to antibody titers after three vaccinations. The latter vaccination is often referred to as a booster shot. 97 study participants had blood tests taken after two vaccinations with an average antibody titer of 440 AU/mL. Any value above 50 was considered to be seropositive. However, 10 to 19 days following the booster shot the average antibody titer rose to 25,468 AU/mL, which is an enormous increase.

Older age patients and kidney transplant patients responding to booster shots

After two vaccinations there were lower antibody titers in older patients aged 67-74 compared to patients age 18-55. But after the booster shot this age difference was no longer present. On the sideline the researcher also followed a group of kidney transplant patients. These would be considered to be patients with a chronic disease. Initially, following the standard two vaccinations these patients were negative for an antibody response. But after the third vaccination (booster shot) 49% of the kidney transplant patients showed a positive antibody test.

Antibody titers in patients with past natural Covid-19 infection

Researchers also investigated the antibody response of patients against the spike protein of Covid-19. A publication showed after a natural Covid-19 infection plus one vaccination of the Pfizer/Moderna vaccine the antibody titer was 20,120 arbitrary units per milliliter. In contrast, the other group consisted of two vaccinations of the Pfizer/Moderna vaccine. They had antibody titers of 22,639 arbitrary units per milliliter. This was not significantly different from the first group. It also did not matter whether in the first group the prior natural Covid-19 infection was 1, 2, 3 or more months before the first vaccination with the Pfizer vaccine.

Discussion

New information emerged since the beginning of the Covid-19 pandemic. There was confusion about how often people would need a vaccination before they would be immune against Covid-19. After one vaccination with the Pfizer/Moderna vaccine the protection rate against Covid-19 is around 50%. After two vaccinations the protection rate is around 95%. Experience with the booster vaccination teaches us that the protection rate is almost 100%. There was no difference between the antibody response of the group with the age of 18-55 and the group with the age of 67-74 after the third shot (booster shot).

But there is a proviso: the immune system must be capable of full activation to produce enough antibodies by the B cells. B cells are the lymphocytes that traveled through the bone marrow after which they started producing antibodies against viruses. As the results with the kidney transplant patients showed, only 49% of them were able to produce positive antibody titers. The reason for this is that kidney transplant patients must take immune system suppressing drugs to avoid a rejection of the kidney transplant.

Other reason for poor antibody response

Other patients with chronic diseases (diabetics, autoimmune disease patients etc.) and patients older than 60 can also have a weaker immune system. Part of this can be when one or more of the 14 supplements is missing that are necessary for a full immune response. It is important before the Covid-19 vaccinations to take the 14 necessary supplements to get a good antibody response.

Booster Vaccinations Against Covid-19 Variants are Very Effective

Conclusion

Several studies showed that the antibody response after the anti-Covid-19 vaccine increases significantly. The measurements revealed that after two injections the antibody titer was 440 AU/mL. After the third (booster) injection the antibody titer increased significantly to 25,468 AU/mL. This explains why some people after one or two vaccinations still may be able to come down with Covid-19, but after the additional booster injection (3^rd vaccination) the immune response in terms of antibody production is 58-fold higher than after the second vaccination. This gives the immune system a full response. Some patients with chronic diseases (obesity, diabetes, autoimmune diseases etc.) will have certain immune deficiencies. This explains a higher infection rate among these people as well as a higher mortality rate. We all can take the booster vaccine against Covid-19. In addition, we can take the 14 immune supplements to stimulate our immune system.

Drugs that May be Useful in the Treatment of Covid-19

By Ray Schilling | Drugs, immune system, vaccinations, Vitamins and supplements

This article deals with drugs that may be useful in the treatment of Covid-19. There are several drugs that may be useful in the treatment of Covid-19. Lately an antidepressant like Luvox has been in the limelight. But antiviral drugs like ritonavir from Pfizer and remdesivir from Gilead Sciences also reduced the number of hospitalized patients with Covid-19. Finally, Merck introduced molnupiravir, an antiviral drug against Covid-19. The health authorities in Great Britain recently approved this drug for use in Covid-19 patients in Great Britain. Apart from drugs, vitamin D3 is still an important factor in preventing and treating Covid-19 as I will mention below.

Luvox for better survival from Covid-19

The Lancet published a study on January 2022 about the effect of Luvox on patients with Covid-19 symptoms. 741 patients received the antidepressant Luvox, 756 received placebo pills. In the Luvox group patients received 100 mg of Luvox twice per day for 10 days. From the Luvox treated patients only 11% had to go to tertiary care for treatment. In contrast, from the placebo group 16% had to go to tertiary care. There were 17 deaths in the Luvox group and 25 deaths in the placebo group. The Luvox group definitely showed a positive effect, although the results were not outstanding. In the following I am discussing other drugs that may be useful in the treatment of Covid-19.

Antiviral agent Remdesivir Improving survival from Covid-19

Here is a run-down of the survival statistics with remdesivir. This drug is manufactured by Gilead Sciences in cooperation with Pfizer. 541 patients received a loading dose of 200 mg on day 1. Subsequently they received 100 mg daily for another 9 days. 521 received placebo pills. The median recovery time in patients with remdesivir was 10 days. Those on placebo pills recovered only after 15 days. The mortality rates were 6.7% with remdesivir and 11.9% for the placebo group on day 15. There was a mortality of 11.4% with remdesivir and mortality of 15.2% with placebo pills on day 29. Although the effect between the remdesivir group and the placebo group was significant, the effect would not be enough to stop transmission of the virus on a population basis. Health Canada made the decision to use remdesivir in severe COVID-19 disease cases.

Merck introduced molnupiravir, another antiviral drug against Covid-19

Molnupiravir was approved in the UK as an antiviral drug for early and moderately severe cases of Covid-19. It is difficult to get data on the Merck’s molnupiravir drug. But this publication states that there is a 50% reduction of mild to moderate cases of Covid-19 cases with molnupiravir. Professor Peter Horby from the University of Oxford pointed out “the proportional reduction in the risk of hospitalisation or death is impressive. But it is important to remember that the absolute risks were 14% reduced to 7%, so quite a lot of people need to be treated to prevent one hospitalisation or death.” Others pointed out that the side-effects are very similar between placebo pills and molnupiravir pills. Overall molnupiravir appears to be a useful addition in the treatment of Covid-19.

Higher doses of vitamin D3 effective in treating and preventing Covid-19

Higher doses of vitamin D3 will mitigate the course of influenza and of Covid-19 coronavirus. Researchers outlined 3 mechanisms of how vitamin D works:

Maintaining tight epithelial junctions making it more difficult for the Covid-19 coronavirus to penetrate.“
Killing enveloped viruses through induction of cathelicidin and defensins.” These powerful antiviral polypeptides can kill viruses that have invaded the bloodstream within 1 to 2 days.”
And reducing production of proinflammatory cytokines by the innate immune system, thereby reducing the risk of a cytokine storm leading to pneumonia.” It is people who get the viral pneumonia that are at a high risk of death. By bringing the blood level up to the higher range of normal, between 50 and 80 ng/mL, patients that have encountered Covid-19 coronavirus are more likely to survive.

Drugs that May be Useful in the Treatment of Covid-19

Conclusion

Beside distancing, the wearing of masks and frequent hand washing other methods are emerging to fight the virus that causes Covid-19. Vaccinations are very effective, although they are less effective in patients with a weakened immune system. But there are also drugs that may be useful in the treatment of Covid-19. Newer studies have shown that the antidepressant Luvox has a mild effect on helping Covid-19 patients. Last year remdesivir came into the market. And this year Merck added molnupiravir, another antiviral pill. We should not forget that vitamin D3 is an effective antiviral vitamin. But it is only effective, provided the patient takes enough vitamin D3. The blood level must reach the high normal level of 50-80 ng/mL vitamin D in the blood. Up to now vaccinations and booster shots are the most effective way to prevent Covid-19 infection. Vitamin D3 and molnupiravir are also very effective.
