NZ Man Left for Dead by Doctors, Cured by Vitamin C

Posted by on August 26, 2010 23 comments

Modern doctors are often deeply over-invested in the use of drugs, and amazingly ignorant of the power of the human immune system, when supported by a healthy diet and optimal nutrition, to defeat disease.

They sometimes exhaust their repertoire of drugs without ever considering using nutritional supplements to support the patient’s immune defense.

An extraordinary illustration comes from New Zealand. It began when Alan Smith, a New Zealand farmer, contracted swine flu:

He caught the Swine Flu (probably while on a fishing trip in Fiji), so badly that his lungs had “white out”, which is to say they were so full of fluid that they didn’t show up on an x-ray. The doctors also said he had got leukemia and he ended up being put on a life support machine.

The doctors told the family the machine should be turned off … [1]

The diagnosis of leukemia is suspicious. Both infections and leukemia lead to “leukocytosis” or a very high white blood cell count. In one case the white blood cells are multiplying to fight the infection, in the other a malignant population is multiplying. The difference is that in leukemia the population is monoclonal, i.e. all the new white blood cells are genetically identical, while in normal people with infections the white blood cells are created with genetic diversity. (Keywords for those who wish to investigate: T-cell antigen repertoire and B-cell immunoglobulin repertoire.)

As subsequent events showed, the leukemia “diagnosis” was mistaken. I wonder if it was made just for “family management” – in order to help persuade the family his case was hopeless and support the recommendation to end life support.

… but the family asked that he be given high dosages of Vitamin C. After a fight (one of many), one of the doctors agreed. Alan began getting better; his lungs showed pockets of air. Then he began to get worse and the family found out the doctors had stopped the Vit C.

Many more fights ensued, the patient getting better while having the Vit C, and getting worse when he was taken off. Alan’s wife describes one of the doctors sitting back in his chair, arms folded, rolling his eyes, looking at the ceiling, telling her that no way could the vitamin C be helping. The family hired a lawyer, forcing the doctors to continue the vit C treatment (albeit in slow dosage, until he got better enough to eat and his wife brought along sachets of large dosage herself for him to take).

Eventually Alan fully recovered, no trace of leukemia even. [1]

He should have been given high doses of vitamin D and iodine as well. Iodine supports leukocyte respiratory bursts of reactive oxygen species which destroy pathogens; vitamin C supports respiratory bursts by recycling glutathione and providing antioxidant protection for leukocytes against their own respiratory bursts, and also supports anti-viral immunity; vitamin D creates antimicrobial peptides that kill many pathogens.

Other possibly beneficial supplements in cases of elevated leukocyte counts due to infection: selenium, to support both glutathione and iodine/thyroid function; iron, for myeloperoxidase (respiratory burst enzyme) and catalase (antioxidant defense); N-acetyl cysteine (for glutathione production) and glutathione; zinc and copper (for the anti-oxidant zinc-copper superoxide dismutase).

Thank goodness the family had the sense to try vitamin C, and that that was enough for him to recover. It would have been a shame if he died for lack of vitamin D and iodine.

New Zealand was a pioneer of socialized medicine in the English-speaking world. Economists say that people respond to incentives; one wonders if the doctors were more motivated to tend to the interests of the bureaucrats who controlled their budgets, than to the health of the family and patient who weren’t paying them. Perhaps “free” medical care has unexpected costs.

Retroviruses and Chronic Fatigue Syndrome

Posted by on August 24, 2010 29 comments

One of the themes of this blog is that chronic infections, exacerbated by bad diets and malnutrition, are at the root of nearly all health problems.

With the invention of new tools for microbiology over the last 20 years, scientists are for the first time able to study chronic parasitic infections, albeit with difficulty. I mentioned a few weeks ago that this should be the dawn of a “golden era of antimicrobial medicine.” And maybe it is: careful studies are now linking specific pathogens to chronic diseases and discovering the mechanisms by which they cause disease.

A good example of emerging science is the progress made since 2002 in understanding a retrovirus family that is now firmly linked to cancer and chronic fatigue syndrome and may soon be linked to other diseases.

Beginning of the Story:  Human Anti-Viral Immunity and Chronic Fatigue Syndrome

Our story begins back in the 1970s with studies of the role of interferons in defending human cells against viruses. Interferons are a key part of the immune defense against intracellular pathogens – the ones that cause most human chronic diseases.

Following the effects of interferons, researchers discovered an enzyme known as ribonuclease L (RNase L). RNase L is upregulated by interferons and its function is to degrade RNA, both viral and human, to stop viral replication. [1]

Aside: High levels of RNase L destroy so much human RNA that the cell dies. This is probably adaptive for the host, since cell apoptosis also kills many pathogens within. However, it shortens lifespan. RNase L knockout mice have extended lifespans. [1]

In 1997, RNase L was found to be strongly upregulated in chronic fatigue syndrome patients. [2] This showed that chronic fatigue patients usually have viral infections. Whether the viruses were causing chronic fatigue, or just “hitchhiking” with a disease that suppressed the immune system (perhaps via a bacterial infection?), remained an open question.

A Link Between RNase L and Prostate Cancer

By the early 2000s it was established that a common (allele frequency 35%) gene mutation, the “R462Q” mutation which substitutes a glutamine for an arginine in the “hereditary prostate cancer 1” locus, raised the risk of prostate cancer. A man with two copies of this mutation has twice the risk of prostate cancer; one copy raises the risk by 50%. About 13% of prostate cancer cases were attributable to this mutation. [1, 3, 4]

It was important, therefore, to determine which protein this locus coded for. A breakthrough finding, made in 2002, was that the “hereditary prostate cancer 1” locus was the gene for RNase L. [5]

It was soon shown that the R462Q mutation decreased the effectiveness of RNase L at cleaving viral RNA. This placed prostate cancer in a new light: it implied that an unknown virus against which RNase L defends was a probable cause of prostate cancer. When RNase L function was impaired by the R462Q mutation, the infection became more virulent, and prostate cancer rates were higher. [1]

The search for this unknown virus was on.

The discovery of “xenotropic murine leukemia virus-related virus” (XMRV)

The strategy was basically to take prostate tumors and search for viral RNA, looking for viruses that were most common in patients who had the double R462Q mutation.

In 2006 one of these searches yielded fruit.  A new gamma retrovirus was found in 8 of 20 prostate cancer patients with double R462Q mutations, but only 1 of 66 patients without the double mutation. [6]

This gamma retrovirus shared a lot of RNA with a family known as the xenotropic murine leukemia viruses (MuLVs). It was dubbed “xenotropic murine leukemia virus-related virus” (XMRV). Despite the sound, it is not a murine (mouse) leukemia virus; it merely shares a lot of nucleic acids with those viruses.

Back to chronic fatigue syndrome

In 2009 a paper was published in Science reporting that XMRV was found in peripheral blood cells of 67% of chronic fatigue patients but only 3.7% of healthy controls. [7] This study was done by a group at the Whittemore Peterson Institute in Reno, Nevada.

Aside:  The Whittemore Peterson Institute has a nice Q&A about this virus and its role in chronic fatigue syndrome here.

A number of researchers tried and failed to reproduce these results. For instance, a group from the Centers for Disease Control failed to detect XMRV proteins in 51 chronic fatigue and 53 healthy patients. [8]

Perhaps proteins are just not the right molecules for detecting this virus. A new paper has just appeared that links XMRV more strongly than ever to chronic fatigue. It looked at DNA for viral genes inserted into the human genome and found XMRV sequences in 86.5% of chronic fatigue patients but only 6.8% of controls. [9] This paper was held back from publication since June because of its conflict with the CDC paper (see “Why I Delayed XMRV Paper”), but has now been released.

These percentages are impressive and, if they hold up, would seem to make it unlikely that XMRV is merely a “passenger” virus hitchhiking on a suppressed immune system. It may be causal for chronic fatigue.

Will anti-retroviral therapies be effective?

Clinical trials are extremely expensive and the drug companies seem to be waiting for XMRV to be proven as the cause of chronic fatigue before undertaking trials. From the Wall Street Journal:

Norbert Bischofberger, chief scientific officer at Gilead Sciences Inc., the leading maker of HIV drugs, said the company might consider a small pilot trial but would like to see stronger evidence that the viruses cause CFS before launching a large trial. Still, “I’m very open, and this would be a great opportunity,” he said.

A spokesman for Merck & Co., another major manufacturer of HIV drugs, said: “A clinical trial program would be possible to develop only after further substantial evidence of an association with CFS.” [10]

But some aren’t waiting for trials. Anti-retroviral drugs developed for AIDS are being prescribed off-label:

Jamie Deckoff-Jones, 56 years old, a doctor and CFS patient in New Mexico, has been blogging about her experiences and those of her 20-year-old daughter. Both tested positive for XMRV and are taking a combination of three anti-retrovirals.

Dr. Deckoff-Jones said a year ago she could only get up for short periods during the day. After five months on the drugs, she flew last week to Reno for an XMRV conference. Her daughter was able to go to a party and is enrolling in community college. “This is all very new, and there is no way to know if improvement will continue,” Dr. Deckoff-Jones wrote in an email, “but we appear to be on an uphill course.” [10]

Chronic fatigue patients are celebrating the progress:

Many [CFS patients] were ecstatic at news that the second study was being published.

“We’re really hoping this will blow the lid off,” said Mary Schweitzer, a historian who has written and spoken about having the illness. “Patients are hopeful that now the disease itself might be treated seriously, that they’ll be treated seriously, and that there might be some solution.” [11]

It’s sad that for decades many haven’t taken chronic diseases seriously. The absence of a known cause reflected only the lack, until recently, of microbiological tools capable of detecting and characterizing intracellular pathogens.

Had doctors taken these diseases seriously, the accumulating evidence that these were chronic infectious diseases caused by intracellular parasites might have encouraged them to look for the sort of dietary and nutritional therapies for chronic disease that we advocate on this blog. Though diet and nutrition by themselves will probably not cure these diseases, they can greatly slow disease progression and improve the odds of a cure.

A new name for XMRV: Human Gamma Retrovirus

The Whittemore Peterson Institute recently hosted the first official scientific symposium on XMRV. Dr. Joseph J. Burrascano reported from the symposium:

We formed a working group to be in constant touch and we plan to meet regularly because advances are coming so rapidly.

Big news that everyone should know and adopt is that we have proposed a name change for the virus.

This virus is a human, not mouse virus, and it is the first and so far only gamma-retrovirus known to infect people. Also, it is clearly not an “endogenous” retrovirus (one that is present in all genomes due to ancient infection).

Because of all of this, and because of the desire to begin on the right track, the new name of the virus is HGRV- Human Gamma Retro Virus. The illness caused by this infection is named HGRAD- Human Gamma Retrovirus Associated Disease.

We plan to announce this at the upcoming NIH retroviral conference this September.

Definitely stay tuned- the volume of new and important information about this virus and its disease associations is increasing rapidly and in my opinion should be a concern to every patient with chronic neuro-immune diseases, including those with chronic Lyme. [12]

It sounds like some exciting findings may be on the way.

Conclusion

This case is a fascinating illustration of the twisting turns that scientific research can take. The early discovery of a link between anti-viral immunity and prostate cancer may now lead to a cure for chronic fatigue syndrome. At least, we can hope so.

As one of the pioneers, Dr. Robert Silverman, describes it,

One of the remarkable aspects of being a scientist, is that you never know where your scientific journey will lead. [1]

Science takes a lot of patience, diligence, and persistence. It’s gratifying when all that work is rewarded by discovery.

Vitamin D Dysregulation in Chronic Infectious Diseases

Posted by on August 21, 2010 45 comments

Commenter qualia recently got his serum 25-hydroxy vitamin D levels tested and found a surprising result: He had doubled his vitamin D intake from 5,000 IU to 10,000 IU per day, but his 25(OH)D levels didn’t budge – they were at 61 and 62 nmol/l, equivalent to 24.4 ng/ml in American units.

24 ng/ml is well below the optimal level for healthy people of 40 ng/ml. When a healthy person supplements vitamin D, the serum 25(OH)D level usually rises linearly with dose up to about 40 ng/ml, then it rises very slowly thereafter as the body tries to keep 25(OH)D from rising by putting vitamin D into storage.

So it was natural for qualia to expect his serum 25(OH)D level to rise when he doubled his dose.

But it didn’t. The stability of his 25(OH)D levels suggests that his body has reached an equilibrium at 24 ng/ml. Instead of plateauing at 40 ng/ml with abundant vitamin D3 as a healthy person would, he is plateauing at a lower level.

Why does that happen?

Well, I don’t know. But I would like to provide qualia with a little bit of background, because this could be a clue that helps diagnose his condition and optimize treatments.

Normal vitamin D regulation strictly controls 1,25D levels

I suggested in the comment thread that qualia get his 1,25D levels measured as well as 25(OH)D.

Levels of 1,25D are not routinely measured, even in scientific studies, because they rarely vary. Blood levels of 1,25D control calcium homeostasis and are tightly regulated. In healthy people, as vitamin D intake rises from zero, serum 1,25D levels shoot up to normal levels before 25(OH)D levels reach 12 ng/ml. They then stay in a normal range no matter how high 25(OH)D levels rise. The kidney is the primary controller of blood 1,25D levels. The normal range is about 16 to 42 pg/ml (42 to 110 pmol/L).

While all human cells can convert 25(OH)D to 1,25D, most cannot release 1,25D into the blood. 25(OH)D freely crosses cell membranes and maintains the same level throughout the body; but 1,25D does not cross membranes. This allows every cell in the body to “personalize” its 1,25D levels to its own needs.

Both 25(OH)D and 1,25D are active ligands for the Vitamin D Receptor (VDR), a nuclear receptor.  [1] When either 25(OH)D or 1,25D binds to the VDR, the compound is imported into the nucleus, where it combines with a vitamin A-activated Retinoid X-Receptor (RXR) to form a transcription factor which, among other roles, upregulates production of antimicrobial peptides (AMPs) that are crucial for cellular defense against intracellular pathogens.

The difference between 25(OH)D and 1,25D is that 1,25D is about fifty-fold more likely to bind to the VDR than 25(OH)D. So by converting more 25(OH)D to 1,25D, cells can upregulate their VDR activation and upregulate their immune defense against pathogens. Meanwhile, uninfected cells can keep their 1,25D levels low. Across human cells, there is a thousand-fold variation in the rate of conversion of 25(OH)D to 1,25D. [1]

In chronic infectious diseases, blood 1,25D is dysregulated

However, in people with chronic infectious diseases, 1,25D levels range all over the map, and are largely uncorrelated with 25(OH)D levels.  Here is a scatter plot from a paper by Dr. Greg Blaney [2]:

The patients in this sample were 100 chronic disease patients: 29 with fibromyalgia, 27 with chronic fatigue syndrome, 12 with post-treatment Lyme Disease, 9 with metabolic disease, 6 with osteoarthritis, 4 with irritable bowel syndrome, 4 with psoriatic arthritis, 3 with multiple sclerosis, 3 with seronegative arthritis, and 27 with other diseases.

Probably all of these diseases are caused by chronic parasitic infections.

A few things to note from this plot: (1) 25OHD levels in a lot of chronic disease patients cluster around the 61 nmol/L level that qualia has; and (2) most chronic disease patients have 1,25D levels well above the normal range, even though their 25OHD levels are mostly below the optimal level in healthy people.

What Causes 1,25D Dysregulation?

Here’s where we get into speculation. There just hasn’t been research exploring this question. Researchers are only just realizing that these diseases are infectious in origin and that vitamin-D-mediated innate immunity is critical to the intracellular immune defense.

Rather than speculate, I’m just going to mention a couple of possibilities.

First, in granulomatous diseases like sarcoidosis, it’s common to have low 25(OH)D and very high 1,25D. Granulomas are nodules where immune cells have been unable to eliminate some foreign matter and instead have built a barrier around it that walls it off from the body.  Granulomas often release 1,25D to the body. Some other granulomatous diseases: 

  • Tuberculosis
  • Leprosy
  • Schistosomiasis
  • Histoplasmosis
  • Cryptococcosis
  • Crohn’s disease

These are all infectious diseases, some of them protozoal in origin.

Second, nearly all human pathogens manufacture proteins or RNA that interfere with the innate immune response. Some are known to interfere with the VDR or with other aspects of vitamin D biology. (The HIV virus blocks the VDR entirely, one reason why it predisposes AIDS patients to infections.) It’s possible that vitamin D dysregulation is brought about by direct pathogen actions to disrupt cellular vitamin D pathways.

Conclusion

The only thing we can conclude with confidence from qualia’s vitamin D tests is that he must have a chronic infectious disease … but he knew that already.

Qualia would be best served by getting advice from an infectious disease specialist with experience in chronic diseases. Such a doctor might be able to narrow down the diagnosis. A diagnosis would help determine which antibiotics might be appropriate to help fight the infection.

Until a doctor’s diagnosis or qualia’s personal experience indicates otherwise, it’s probably prudent to continue with a reasonable intake of vitamin D and to increase iodine as quickly as possible. (Even this is not certain: the standard advice is to minimize vitamin D in granulomatous diseases.) Other infection-fighting supplements, like vitamin C, N-acetylcysteine, and glutathione are likely to be helpful also.

Finally, I always recommend that anyone with a chronic disease find a good discussion forum, like the one at http://cpnhelp.org, and try to find people with similar disease histories and learn from their experiences.

Best of luck, qualia, and please keep us posted.

Why You Shouldn’t Supplement Calcium

Posted by on August 20, 2010 47 comments

Much of the advice handed out by medical doctors is unreliable.  One reason is that the research on which that advice is based is often conducted by specialists who overlook effects beyond their scope of professional interest.

We’ve mentioned previously the example of statin research. Statin studies are generally performed by cardiologists and in the U.S., many statin studies reported only heart attacks and other cardiovascular events as endpoints, not total mortality, cancer, or infectious disease. This method of evaluating drugs would show a lethal neurotoxin to be the best cardiac treatment ever:  In the neurotoxin group not a single patient would die of a heart attack!

A similar myopia has occurred in osteoporosis research, where doctors have focused on the effect of calcium supplements on bone density or fracture rates but often do not evaluate the effect of the supplements on overall health.

But other effects have to be considered, given that:

  • Calcification of coronary arteries may be the best single indicator of heart attack risk. [1]
  • In the Nurse’s Health Study, supplementation of calcium increased the risk of calcium oxalate kidney stones by 20%. [2]
  • Calcium is a strong promoter of biofilm formation in most pathogenic bacterial species. [3] It also likely promotes formation of Candida albicans (fungal) biofilms. As a result, it can aggravate bowel disorders and infectious diseases.

Clearly, calcium in the wrong places – a problem that could be exacerbated by calcium supplementation – is a major health risk.

What causes calcium to go in the wrong places? Deficiencies of vitamin D and vitamin K2 are common reasons. Deficiencies of both are widespread. Vitamin K2 deficiency is a known cause of vascular calcification.

A few years ago, a group of New Zealand researchers conducted a randomized clinical trial that found that over five years, older women taking calcium supplements doubled their risk of heart attack compared to women taking a placebo. [4]

Now, the same group has conducted a systematic review of calcium supplementation studies which confirms the link between calcium supplementation and heart attacks. Dr. Mark Bolland of the University of Auckland, New Zealand, and colleagues report that calcium supplementation increases the risk of heart attack by 31%, the risk of stroke by 20% and the risk of death by 9%. [5]

In an accompanying editorial, Dr. John Cleland writes:

Calcium supplements, given alone, … are ineffective in reducing the risk of fractures and might even increase risk, they might increase the risk of cardiovascular events, and they do not reduce mortality. They seem to be unnecessary in adults with an adequate diet. Given the uncertain benefits of calcium supplements, any level of risk is unwarranted. [6]

We concur. A healthy diet, including dairy and green leafy vegetables, not to mention a daily multivitamin (ours contains 200 mg calcium), should provide a sufficiency of calcium as long as vitamin D levels are normal. If you’re worried about bone health, supplement with vitamins D, K2, and magnesium citrate – not calcium.
