Fat Deposits Mean Higher Covid-19 Risk

A new study showed that fat deposits mean higher Covid-19 risk. This study was reviewed here.

The article is based on the June 10, 2020 publication of the British Medical Journal.

They did large population studies showing that obesity is an independent risk factor for severe disease and death from Covid-19. One study with 428,225 participants had 340 admitted to hospital with confirmed Covid-19 coronavirus. 44% of them were overweight and 34% were obese. Another study, the OpenSAFELY study used linked electronic health records. 17,425, 445 participants were included and 5,683 Covid-19 deaths occurred. In this study there were 29% overweight and 33% obese persons. The researchers noted a dose-response relationship between excess weight and severity of Covid-19. The researchers removed confounding factors like age, sex, ethnicity, and social deprivation.

Critical illness and death rates in overweight and obese people

They realized that critical illness caused by Covid-19 was increased compared to normal-weight people as follows.

  • Covid-19 risk 44% higher in overweight people
  • Covid-19 risk 97% higher in people with obesity

This means that the risk for serious illness from Covid-19 was 1.44-fold for overweight persons and 1.97-fold for obese persons compared to normal-weight controls. The OpenSAFELY study also looked at the death rates from Covid-19 for people with obesity. Two obesity categories were investigated: obesity with a BMI of 30-34.9 and BMI of greater than 40 compared to normal-weight controls. Here are the death rates.

  • BMI of 30-34.9: 1.27-fold increased risk
  • BMI of greater than 40: 2.27-fold risk

Possible mechanisms explaining fat deposits mean higher Covid-19 risk

The researchers mentioned three possible mechanisms why overweight and obese people may have higher Covid-19 disease and death rates than normal-weight controls.

First, angiotensin converting enzyme-2 is found with higher frequency in fat cells of overweight and obese persons. Researchers are aware of the fact that the Covid-19 coronavirus uses this enzyme to enter body cells. It may also be the reason that fat cells become reservoirs that can shed virus for much longer than in normal-weight people with less fat cells. They pointed out that others have seen this also and found it with other viruses. In the case of influenza A, obesity prolonged viral shedding by 42% compared to normal-weight controls. And with H1N1 influenza obesity was an independent risk factor for hospitalization and death.

Weaker immune system, more lung resistance

Secondly, any virus can weaken the host’s defence of the immune system. Researchers showed this previously with the influenza virus. But now with Covid-19 coronavirus the cytokine storm due to a weak immune system is a major factor in making the viral infection worse. A lack of vitamin D is another factor in promoting the cytokine storm.

Third, obesity decreases lung function and it is difficult to improve this. There is greater lung resistance in the airways and it is difficult to expand the lungs in obese patients. When the doctor transfers patients with obesity to the intensive care unit, it is more difficult to increase their oxygen saturation with artificial ventilation.

Unhealthy environment, so fat deposits mean higher Covid-19 risk

The researchers point out that we live in a very unhealthy environment. In 2016 there were 1.9 billion people worldwide who were overweight or obese. These figures are rapidly rising. Presently about 65% to 70% are overweight or obese in the UK or the US. Obesity causes high blood pressure, heart disease, strokes, type 2 diabetes and cancer. We are all surrounded by processed food with extra salt, sugar, wheat and other unhealthy ingredients. The high mortality and deaths rates of Covid-19 in overweight and obese people point to the problem that society has.

Reduce salt, sugar and saturated fats in food

The culprits are salt, sugar and saturated fats. Merchants and food producers must reduce them in processed food. In the UK new government regulations have already resulted in lower salt content in foods. As a result, there is less high blood pressure and cardiovascular disease is in decline. All nations need to reduce salt, sugar, and saturated fat. When the weight comes down, we all are less prone to catching dangerous viruses.

Conclusion

The pandemic has taught us a new lesson, namely that overweight and obese people are at higher risk of contracting Covid-19 coronavirus. In a research paper of the British Medical Journal concrete figures showed that the Covid-19 risk is 44% higher in overweight people and that it is 97% higher in people with obesity. The OpenSAFELY study also showed that obese people with a BMI of 30-34.9 have a 1.27-fold increased risk of catching Covid-19. But morbidly obese people with a BMI of greater than 40 have a 2.27-fold risk of catching Covid-19. There is a clear linear dose-response curve between the amount of fat a person accumulates and the risk for Covid-19.

Cut out junk food and decrease your risk for Covid-19

Covid-19 is directly related to the amount of junk food we eat. As a result we can say that eating junk food increases the Covid-19 risk. The opposite is true also: sensible eating and cutting out junk food makes you lose some pounds, and your risk for Covid-19 decreases.

Bioidentical Hormone Replacement

In many previous blogs I have mentioned that bioidentical hormone replacement prolongs life. Here is a more detailed look at what such hormone replacement looks like for both women and men. Before I get into details I want to stress that I am talking about replacing what is missing and replacing only with natural hormones, not some artificial hormone derivative produced by a drug company. The reason this is immensely important is that hormone receptors in the body are distributed all over our vital organs including bones, blood vessels and the nervous system. If there is no lock and key fit (bio-identical hormone fitting the hormone receptor), there is trouble as the Women’s Health Initiative in 2002 has shown. Unfortunately they had used synthetic hormones for HRT that were not fitting the hormone receptors, and this caused many problems (heart attacks, strokes, osteoporosis, cancer).

Physiology of aging

As we age, we gradually produce fewer hormones in our hormone glands, but the various hormone glands deteriorate in their functions at different rates. Beyond the age of 30 we produce less melatonin and less growth hormone. As a result our sleep pattern may change, as melatonin is necessary for a deep sleep. The decreasing growth hormone production means that we are losing some of our muscle mass and accumulate more fat in the subcutaneous tissues. Our adrenal glands produce less DHEA at the age of 35 to 40, a hormone that is a precursor to our sex hormones in males and females. The gonads (testicles and ovaries) also produce fewer hormones, a process which already starts 5 years before menopause and about 5 years before andropause (the male menopause equivalent).

Typically a woman will get into menopause at the age of 45 to 55 at which time the periods stop and postmenopausal symptoms are interfering with her well-being.  Men get into andropause (the male equivalent of menopause) at the age of 55 to 65 at which time erectile dysfunction occurs and often the individual will become the “grumpy old man”.

Other hormones such as thyroid hormones are also affected by the slow down. Hypothyroidism is common in people above the age of 50.

Baseline laboratory tests

In order to know what is going on, the physician or naturopath needs to order a number of tests to assess whether there is inflammation, how your key hormone levels are; the cardiovascular system markers should also be checked, the liver enzymes and vitamin D3 level. Inflammatory markers are fasting insulin levels and C-reactive protein (CRP). Fasting cholesterol and subfractions (HDL, LDL, VDLP, small LDL) and fasting triglycerides are also measured. Thyroid hormones (T3 and T4, TSH) are measured to rule out over or under function. Typically hypothyroidism is found, which would have to be rectified by taking Armour (a mix of T3 and T4 thyroid hormones).

At this point I need to explain that long time ago the research by Dr. Lee has shown that progesterone hormone levels are notoriously unreliable when blood tests are done. All of the other sex hormones, and cortisol are also not that reliable with blood tests. For this reason the saliva hormone tests have been invented that conveniently report a panel of 5 hormones from one saliva sample: DHEAS (which is the storage form of DHEA), estradiol (the major estrogen in a woman), progesterone, testosterone and cortisol. The saliva hormone tests correlate very well with the actual tissue hormone levels. You can order the saliva tests through Dr. Lee’s website. Another longstanding lab in the US is Dr. David Zava’s lab. In Canada the Rocky Mountain Analytical Lab can process your saliva tests.

Women’s hormone replacement

Let us assume that a woman is getting postmenopausal symptoms and bioidentical hormone replacement is being discussed. The physician will want to first rule out that insulin resistance is not present by ordering a fasting insulin level. If this is normal and the other baseline tests are normal as well except for missing estrogen and progesterone, the physician will usually start to replace progesterone first using a bioidentical hormone cream to be applied once or twice per day. If estrogen levels were also low, the next step in 4 weeks or so is to add Bi-Est, a bioidentical estrogen replacement cream. After 8 weeks of hormone replacement the saliva hormone test is repeated to see whether the estrogen and progesterone levels have come up and also, whether the ratio of progesterone to estrogen is at least 200 or more. Dr. Lee has extensively researched this and found that women with a ratio of less than 200 to 1 (progesterone/estrogen ratio) were more prone to breast cancer. He also stated in this link that there are 3 basic rules with regard to bioidentical hormone replacement:

1. only replace hormones, when they were measured to be low.

2. use only bioidentical hormones (never synthetic hormones) and

3. only replace with low doses of bioidentical hormones to bring hormone levels to physiological levels (body levels that were experienced to be normal before).

Many women who are not replaced in menopause have estrogen dominance meaning that the progesterone/estrogen ratio is less than 200:1, which puts these women at risk of developing breast cancer. Women who are overweight or obese also are estrogen dominant (from estrogen produced in excess through aromatase in the fatty tissue, explained further below), which makes them more prone to breast cancer, uterine cancer and colon cancer. Without bioidentical hormone replacement inflammatory processes take place in the joints (causing arthritis), in the nervous system (causing Alzheimer’s and dementia) and in the blood vessels (causing heart attacks and strokes). Rebalancing your hormones to a youthful state by paying attention to the hormone levels and the hormone ratios mentioned will remove the inflammatory reactions and reduce the risk for cancer.

Men’s hormone replacement

Males enter andropause 10 to 15 years later than women are entering menopause. Typically testosterone production slows down leading to hair loss, erectile dysfunction, loss of muscle mass, osteoporosis and Alzheimer’s/dementia. Blood tests (bioavailable testosterone) or saliva tests are both reliable in determining a deficiency. Replacement with bioidentical hormone creams once per day is the preferred method of treatment. Overweight and obese men produce significant amounts of estrogen through an enzyme localized in fatty tissue, called aromatase.

Aromatase converts testosterone and other male type hormones, called androgens, into estrogen. Estrogen causes breast growth, weakens muscles, and leads to abdominal fat accumulation, heart disease and strokes.

Similar to women, where the progesterone/estrogen ratio is important, there is another ratio for men, called testosterone/estrogen ratio. This should be in the 20 to 40 range for a man to feel good and energetic. Unfortunately many men above the age of 55 have testosterone/estrogen ratios much smaller than 20. This makes them more prone to heart disease and prostate cancer (Ref.1).

However, a male also does need a small amount of estrogen and normal thyroid hormones as well as all of the other hormones for his “hormonal symphony” (mentioned in Ref. 2) to function at his best.

Safety of hormone replacement

There are still otherwise reputable websites that state that bioidentical hormones are not safer than standard synthetic hormones. This confuses the consumer and does not serve the public well. I much prefer the text of the Wikipedia, which is a more thorough review regarding safety of hormone replacement and explains what the issues are.

In the US there is a collective experience of about 25 years on thousands of patients, but there have not been any randomized studies, as Big Pharma that would have the money to finance such studies is not interested in proving that bioidentical drugs would be safer than their distorted synthetic hormone copies that will not fit the body’s hormone receptors. There are some noble exceptions as Big Pharma is producing bioidentical insulin and human growth hormone that had toxicity studies done and showed safety. In Europe bioidentical hormones have been used since the 1960’s, on a larger scale since the 1970’s. So the European experience of safety of bioidentical hormones is presently about 40 to 50 years.

The FDA is contributing to the confusion of the public as can be seen from this publication. One example where the FDA is confusing the consumer, is the progesterone product Prometrium, a bioidentical micronized progesterone capsule that can be taken by mouth. By law the manufacturer had to put a warning label on the package identical to progestin, which is the synthetic, non-bioidentical hormone having been shown to have severe side effects. As is explained in this last publication Prometrium should not have been required to have a warning label in it ; the paper explains what I have already stated above, namely that bioidentical hormones are the safest form of hormone replacement and administered in the right ratios will actually prevent cancer and prevent premature cardiovascular and joint deterioration. In other words, bioidentical hormone replacement can add many years of useful life when started early enough before permanent organ damage sets in from the aging process (which would be due to missing hormones).

Why bother about hormone replacement?

Nature has a plan of “knocking us off” to make room for the next generation. The only way that you can change nature’s plan of killing us prematurely through cardiovascular disease, arthritis, dementia and loss of your sexual life is by bioidentical hormone replacement. Of course you also need the other ingredients of known life prolongers such as healthy (preferably organic) foods, exercise and detoxification. Many women are scared to treat the hormone deficiencies that cause their menopausal symptoms because of the Women’s health Initiative results with synthetic hormones. Men who would benefit from testosterone are often anxious that they may get prostate cancer, when in reality it is the exact opposite: testosterone prevents prostate cancer (Ref.3).

Conclusion

I wrote this blog about bioidentical hormone replacement in order to clarify this often-misunderstood topic. Don’t get confused by the FDA, by highbrow medical websites (such as the likes I mentioned). Big Pharma has a powerful lobby that attempts to keep the medical profession in the belief that their products are better than those that nature has provided (I call it “defend your patent rights”). We are still in a flux state where anybody who tells the truth about hormones gets much criticism. In another few decades it will be an accepted fact and people will wonder why the Women’s Health Initiative was done without a control with bioidentical hormones. With bioidentical hormone replacement you can add about 20 years of youthful life without disabilities to the normal life expectancy. Exercise, detoxification and organic food with avoidance of wheat, starch and sugar can add another 5 to 10 years to your life. The baby boomers are lucky that they have this new tool to prolong life. I wonder whether they will put it to good use.

Lowering Cholesterol Aggressively Saves Lives

A 5-year multinational prospective study (“Treating to New Targets or TNT Study” involving top cardiologists from around the world has found significant benefits in using higher doses of statins. They investigated the effects of increasing the statin concentration (a cholesterol lowering medication) and have now come to new insights how to approach the metabolic syndrome, which is the metabolic derangement associated with obesity. Of 10,001 patients aged 35–75 years with clinically proven heart disease 5,584 patients had metabolic syndrome at the same time. Half of them were put on 10 milligrams of Atorvastatin (brand name: Lipitor, made by Pfizer Inc.), the other half on 80 milligrams per day. They were followed for 5 years and many questions were asked, blood tests done and statistics kept. Of particular concern was whether survival rates and numbers of heart attacks or strokes would be different for the various groups. The major focus of interest was on people who were over weight or obese.

As the image above shows, percentages of complications (heart attacks and strokes) were used as clear end points of cardiovascular complications to measure the response to the statin. The results showed that two subgroups of obese patients, those who have at the same time diabetes and those who don’t, were both benefitting from the higher dose of Lipitor in an equal manner (about a 30% relative reduction of risk).

The amazing result was that dosage of the statin mattered very much. In the past it was thought that taking a pill for high cholesterol was all that mattered. However, now we know that physicians need to watch the blood level response of the bad cholesterol (LDL cholesterol) and titrate the abnormal levels down to a normal level by using adequate dosing. The authors came to the conclusion that metabolic syndrome patients with heart disease, and particularly those where diabetes was present at the same time, would need more intensive statin therapy (higher dosage) than patients who were only having cardiovascular disease. The new goal post for lowering the low-density lipoprotein cholesterol (LDL cholesterol) of 1.8 mmol/L (70 mg/dL) was recommended.

5-Year Study Shows Further Reduction of Major Cardiovascular Complications In Patients
(Expressed as %) With Metabolic Syndrome Using Higher Doses of Atorvastatin(P. Deedwania et al. Lancet 368, No. 9539: 919-928, Sept. 9, 2006)
 

 

 

 

 

 

 

 

 

 

This study showed that there was a 44% increase in absolute risk for an adverse outcome in coronary heart disease patients who also have metabolic syndrome than those without metabolic syndrome. This justifies a very aggressive treatment with Lipitor down to the new target blood values indicated above that your doctor needs to monitor. In high risk patients for heart attacks and strokes where more than 3 cardiovascular risk factors are present the patient’s outlook (longer survival) can be improved by several years. This was shown with treatment using the higher dose of Lipitor when blood levels and cardiovascular complications were compared between 5 years of treatment and the treatment results after the first year of the study.

Prostate Cancer Recurrence Linked To Obesity

Prostate cancer affects a significant percentage of male patients in the higher age groups. Early diagnosis and treatment has shown good success rates. Early surgery in the form of a radical prostatectomy has given patients virtually a new lease on life. Radiotherapy as an alternative form of treatment has been an option for those who could not undergo surgery. Once the treatment is completed there is reason for optimism, if the tumor could be removed in total.

Dr. Sara Strom, PhD and research colleagues from the M.D. Anderson Cancer Center in Houston, Texas analyzed findings of 873 patients over the course of 14 years with localized prostate cancer who had received external beam radiotherapy as their sole treatment. The objective was to determine, whether all patients were doing well, or whether some could be more at risk. It turned out that those with normal body weight fared best. 27% of them experienced a recurrence of the disease. Those who were overweight had recurrence rates that jumped to 55%. Those who were obese were most severely affected with recurrence rates of 99%. The researchers believe that there is a difference of tumor behavior between patients with normal body weight and those who are overweight or obese.

Prostate Cancer Recurrence Linked To Obesity

Future studies will be needed to evaluate the relationship of obesity with dietary factors, genetic modifiers of steroid androgen metabolism, insulin and insulin like growth factors. This will clarify the underlying mechanism of action in the development of prostate cancer.
