Welcome! This blog contains research & information on lifestyle, nutrition and health for those with MS, as well as continuing information on the understanding of the endothelium and heart-brain connection. This blog is informative only--all medical decisions should be discussed with your own physicians.

The posts are searchable---simply type in your topic of interest in the search box at the top left.

Almost all of MS research is initiated and funded by pharmaceutical companies. This maintains the EAE mouse model and the auto-immune paradigm of MS, and continues the 20 billion dollar a year MS treatment industry. But as we learn more about slowed blood flow, gray matter atrophy, and environmental links to MS progression and disability--all things the current drugs do not address--we're discovering more about how to help those with MS.

To learn how this journey began, read my first post from August, 2009. Be well! Joan

Boosting Immune Cells

Anne Kingston, reporter and senior writer at Maclean's Magazine, has just published a fantastic interview with pioneering neuroimmunologist Michal Schwartz.   I've recommended Dr. Schwartz's new book, Neuroimmunity: A New Science That Will Revolutionize How We Keep our Brains Healthy and Young, on this blog.  I'm thrilled that Anne not only read the book,  but got in touch with Dr. Schwartz and interviewed her, to learn even more.
http://www.macleans.ca/society/health/a-healthy-immune-system-is-the-key-to-a-healthy-mind/

I found this particular question especially insightful.

Anne Kingston: Your research indicates the immune system needs to be boosted, not suppressed. Doesn’t that run contrary to the immunosuppressant therapies routinely prescribed for many autoimmune diseases?

Dr. Schwartz: I’ve told everyone for a while to be careful when prescribing any anti-inflammatory drug for any neurodegenerative disease. They understand, but don’t have an alternative.


In other words, since there's nothing better, neurologists haven't changed their treatment target.  They understand that immune suppressing drugs (also known as anti-inflammatory) are keeping helpful immune cells away from the brain, but they don't have anything else they can prescribe which is FDA approved.  Here's more on the FDA pay to play system, which is maintaining the current $20 billion a year MS treatment industry.
http://ccsviinms.blogspot.com/2013/10/the-fda-and-multiple-sclerosis.html 

The last several years of research have directly questioned the current MS treatments.   Recent discoveries of the brain's lymphatic vessels and connection to the immune system and the neuroprotective role of immune cells.  The fact that the brain is not immune privileged and needs immune cells to repair the blood brain barrier.  The glaring fact that this immune cell and lymphatic cleansing system is relient on functioning venous drainage system  ---- in light of all of this research, the continued silence of the MS community is deafening.  They carry on as if nothing has changed, still prescribing immune cell sequestering and ablating medications, without a second thought.  They ignore vascular issues and the compounding evidence that cardiovascular lifestyle intervention can modify disease progression.   

Why?  They understand the science, but they don't have an FDA-approved alternative to sell MS patients.

Readers of this blog know that the current mouse model for MS, called experimental autoimmune encephalomyelitis (EAE) is not an appropriate model for MS.  EAE it is initiated by injecting the mice with lots of stuff we certainly don't find in the CNS of humans with MS, in order to create an inflammatory reaction.

Did you know that the MS drug Copaxone was originally created in an attempt to CAUSE the animal model of MS?   It was formulated to give mice EAE?  That's right.
http://www.ncbi.nlm.nih.gov/pubmed/20106343 

Glatiramer acetate (GA) was created in a lab over 40 years ago to cause EAE.   It consists of four synthetic protein compounds combined together to replicate myelin basic protein (MBP.)  Myelin basic protein is what the immune system damages in MS.  So, the idea was, inject the animals with this myelin-like formulation, and the immune system would go to town and attack ---creating an MS-like disease process, and disabling the mice.

What actually happened, however,  was the exact opposite. The animals injected with GA could not develop EAE.  What happened was that this formulation did indeed activate t-cells and boosted an immune reaction,  but these t-cells were not damaging, they were protective.
http://www.jimmunol.org/content/186/4/1887.full.pdf

This is how Copaxone was developed to treat humans--what MS researchers like to call serendipity, I think is essential to understand.  Copaxone is not an immune ablating or suppressing drug, it is an immune boosting drug.

Glatiramer acetate, now called Copaxone, was created in a lab at the Weizmann Institute in Israel. Not coincidently, this is the same institute where Dr. Schwartz has been conducting her research.  It would be the discovery of how GA increased the body's t cells and protected axons which would coincide and overlap with her studies.

Boosting immune cells, instead of suppressing them, protects the central nervous system. 

Granted, we now know Copaxone is most certainly not a cure for MS.  Although it blocked EAE in mice, its longterm efficacy in humans with MS is more of a mixed bag.  But what the creation of Copaxone should have instigated, at least in mind, were questions regarding the long-term safety of serious immune ablating treatments for MS and the development of immune boosting and modulating treatments.

"They understand, but they do not have an alternative."

Let's continue to put pressure on MS researchers for alternatives.  For immune modulating treatments, for venous treatments, for cardiovascular therapies, for immune boosting treatments. It's vitally important to study the endothelium, the connection between the vascular and immune systems.

Until we understand more, please be careful with serious immune cell sequestering MS drugs (like Tysabri, Gilenya, Tecfidera) or immune ablating chemotherapies (like Campath and Lemtrada.)   Do everthing you can do to live your best vascularly, endothelially, heart-healthy life.

The research keeps coming in.  And we do not know what we do not know.

be well,

The brain needs immune cells

In 2010, Dr. Alasdair Coles, an academic neurologist at Cambridge University, said to the press:
'We know MS is an auto-immune disease because if you block the immune response with drugs, people get better.'
This now infamous quote from Dr. Coles came when he was asked to comment on Jeff's treatment for CCSVI, as reported in the UK's Daily Mail.

In my mind, linking the cause of MS to how the drugs work (for some) is akin to saying, 
"We know the earth is flat because we don't fall off!"
The relationship between the brain and immune system is much more complex than ever imagined.

Labeling MS a classic autoimmune disease is a serious misnomer--since we see the same immune cell reaction to myelin after hypoxic injury and stroke.

Demyelination and axonal injury are characteristics of MS but are also observed in stroke. Conversely, hallmarks of stroke, such as vascular impairment and neurodegeneration, are found in MS. However, the most conspicuous common feature is the marked neuroinflammatory response, marked by glia cell activation and immune cell influx
http://www.ncbi.nlm.nih.gov/pubmed/26527183
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4162361/

There are no antigen specific antibodies in MS. There is no specific immune target in Multiple Sclerosis.  
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1168912/ 
http://www.ncbi.nlm.nih.gov/pubmed/26265268?dopt=Abstract

And, thanks to new research, we now know that immune cells are vital to a functioning brain.  

1.They provide healing after a break of the blood brain barrier, as we see in MS.
http://www.pnas.org/content/113/4/1074.abstract
2.They aid healing of axons after injury to the central nervous system, via glial scar formation
http://www.ncbi.nlm.nih.gov/pubmed/24756949
3.The "autoimmune" t cells often ablated in MS treatment are also responsible for neuroprotection.
http://www.ncbi.nlm.nih.gov/pubmed/12374425

At the time of his quote, Dr. Coles was bringing his life's work to market--the chemotherapy drug Alemtuzumab, repackaged for MS as Lemtrada.  Cole's overarching premise in his research is that the immune cells in multiple sclerosis are completely damaging to the brain, and need to be entirely removed.

And his theory then that "people get better" when the immune system is ablated is actually not true.  Yes, inflammation is tamped down in those with RRMS.  But, just like swatting a pesky fly with a sledgehammer, there is a lot of residual damage.   Immune ablation with chemotherapy has a host of horrific side effects, including fatal cancers, fatal viral and bacterial infections, worse autoimmune reactions in other parts of the body including kidney failure, lung tissue swelling, and hypothyroidism.  Not necessarily "all better!"  Which is why this medication has a black box warning, 
http://www.fda.gov/downloads/Drugs/DrugSafety/UCM426512.pdf

Meanwhile, Dr. Coles is busy trying to create an antidote to stop the new autoimmune diseases his drug has caused.  That's right...Lemtrada actually causes autoimmune disease!
The principal adverse effect of alemtuzumab (Lemtrada) is autoimmunity, which arises when reconstitution of the immune repertoire after alemtuzumab occurs by homeostatic expansion of residual lymphocytes. Therefore we are now testing the ability of keratinocyte growth factor to promote thymic lymphopoiesis and so prevent autoimmunity after alemtuzumab, in a MRC-funded clinical trial.
http://www.neuroscience.cam.ac.uk/directory/profile.php?Alcool

Even worse,  the MS disease process does not stop with Dr. Cole's Lemtrada.  Cerebral atrophy and disability continue, even without any new lesions.

Unfortunately, this did not lead to a clinical improvement in the disability in these patients. In fact, their disability worsened with time at a rate of 0.02 EDSS points for each patient each year. Evidence for continued neurodegeneration in these patients was shown by progressive cerebral atrophy on follow-up MRI scanning. 
http://europepmc.org/articles/PMC3629751


In the past decade, a narrative developed in the MS drug industry by MS researchers like Dr. Coles:  the idea that the immune system is at fault, and needs to be halted.   This has led to the creation of a class of drugs which create "lymphocyte sequestration" and "lymphocyte depletion"---meaning they keep the white blood cells walled off in the lymph tissue or deplete them, keeping them out of the body's circulation.  Instead of allowing immune cells protective entry into the body and around the brain, they are held back.  This new class of more powerful disease modifying drugs include Tysabri, Gilenya and Tecfidera.  

Not surprisingly, there is a price to pay when you hold back immune cells, deplete them, and don't let them do their job.  And one of those side effects is the reactivation of latent viruses and bacterial infections, including the John Cunningham virus (JCV).  This virus causes the deadly brain infection, progressive multifocal leukoencephalopathy (PML).  

Neurologists have comforted their patients regarding their PML risk and Tysabri use, telling them that if they were tested as JC virus negative, they would remain that way and not to worry.   But this was simply not true.  

The JC virus is very common in the general population, infecting almost 90% of us in childhood.  It stays under control and latent because our immune system keeps it in check.  This means we have a JC negative status.  The virus is able to cross the blood brain barrier where it attacks myelin and destroys brain tissue.  

New research shows that the risk of JCV reactivation due to Tysabri use is ten times higher than previously estimated.  That not 1%, but 10% of all patients on Tysabri were seen to go from JCV negative status to JCV positive status while taking Tysabri.  The drug is apparently what turns people from JC virus negative to positive.  This makes sense, if you understand that what Tysabri is doing is holding back immune cells, and rendering them unable to stop a virus from reactivating.
http://nn.neurology.org/content/3/1/e195.full

It also makes sense as to why Tecfidera and Gilenya have now been linked to PML...and I fear it's only a matter of time until real world reporting comes in showing JCV reactivation on these drugs.
                                                              +++++++++++++  

Dr. Michal Schwartz has been publishing on the importance of immune cells for brain health for decades.  Both she and Dr. Nedergaard are two of my research heros.  They are brilliant, determined women who have challenged the neurological status quo and are actively publishing their findings.

Dr. Schwartz explains her decades long search in understanding the importance of the immune system for the brain in her new book,  Neuroimmunity: A New Science That Will Revolutionize How We Keep Our Bodies Healthy and Young.
http://www.weizmann-usa.org/media/2015/09/22/prof.-michal-schwartz-will-change-your-mind

This book is simply wonderful!  It is written clearly and simply, so that lay people might understand her research.  But it is also in-depth enough to appeal to researchers.  All of her publications are cited.

Scientists long believed that there was no communication between the brain and the immune system; in fact, it was thought that any infiltration of immune cells into the brain was a major threat to our health. Based on this assumption, the standard treatment for inflammation associated with neurodegenerative diseases, such as Alzheimer’s, was to totally suppress the body’s immune system.

Prof. Schwartz turned this theory on its head by proving that the immune system and the brain do “speak” to each other – and that, in fact, neurodegenerative diseases are the result of a communication breakdown between the brain and the immune system. Instead of suppressing the immune system, she argues that the most effective way to treat Alzheimer’s and other chronic neurodegenerative diseases is to do the opposite: boosting targeted immune cells in the brain. 

The brain needs immune cells.

Please, if you have MS--- until we understand more about the immune system and brain health, make sure to discuss this new research with your neurologist, especially if they are putting pressure on you to try these new immune ablating and lymphocyte depleting drugs for MS.  New research is coming in every single day, showing that this method might not be the best approach for long-term brain health.

Be well, be curious.
The earth is not flat.

Independent review of new MS Drugs--Must Read

Prescrire ("to prescribe" in French) is a French medical journal, which uses evidence based science to make recommendations on drugs.  It is written by health care professionals for health care professionals,  but it is unique in that it does not accept any pharmaceutical monies for advertising or for payment to reviewers.  This journal makes money by having 33,500 subscribers---medical professionals who turn to this journal for unbiased information. This is a completely independent journal---they have signed a "Non, Merci" (no, thank you) charter to maintain no conflicts of interest.  
http://english.prescrire.org/en/82/173/0/0/About.aspx

Prescrire’s subject matter mainly consists of critical reviews of medicines and other treatment options. Prescrire’s editorial staff is made up of healthcare professionals, most of whom are in active practice. Editors are specially trained and are free from any ties to pharmaceutical or other companies doing business in the healthcare arena. Prescrire’s reviews therefore help healthcare professionals to prescribe for their patients in an informed and fully independent manner.

Prescrire is also completely independent of all national and supernational institutions that determine or implement healthcare policy. Prescrire is therefore free to make recommendations in matters of ethics, public health and national and international healthcare policy.
Prescrire is written and edited by and for healthcare professionals. You could say that it’s just what the doctor ordered.

http://english.prescrire.org/en/82/169/0/322/About.aspx


And Prescrire's March issue has some startling information on MS drugs.  The reviewers names are not published (to keep them safe?) but they stand behind their recommendations.  Each article submitted has been reviewed by 20-40 other peer-reviewers.   And what they say is that when looking at all of the data we now have, these new drugs are too dangerous, with too many side effects and known and unknown risks.  That people with MS are much better off using the first line meds (interferon and copaxone), because these new, more powerful drugs have had biased trials, and have not proven any long term benefit.


1.  Tysabri and MS.  With longer follow-up:  even more toxic than suspected.
http://www.ncbi.nlm.nih.gov/pubmed/25897454
Post-marketing data confirm the adverse effects identified in clinical trials, including serious and life-threatening opportunistic infections, particularly progressive multifocal leukoencephalopathy in about two per thousand treated patients (an incidence twice as high as initially estimated), and potentially severe hypersensitivity reactions. An increased risk of cancer in the long term cannot be ruled out. Post-marketing data also show that natalizumab can cause severe liver damage. In addition, natalizumab withdrawal because of progressive multifocal leukoencephalopathy almost always triggers an immune reconsti- tution syndrome that can lead to neurological complications or even death. In practice, regardless of the severity of multiple sclerosis, it does not seem reasonable to expose patients to the many serious adverse effects of natalizumab for such an uncertain benefit.

2. Lemtrada and MS.  Biased evaluations, evidence of serious risks
Clinical evaluation in multiple sclerosis is based on three unblinded trials comparing alemtuzumab with interferon beta-1a. These trials were all biased in favour of alemtuzumab and thus fail to establish the potential value of this immunosuppressant. Overall, adverse effects, including the most severe, were more frequent with alemtuzumab than with interferon beta-1a. The adverse effects of alemtuzumab reported in these trials had already been observed in cancer patients. They included potentially severe reactions to the infusion, as well as a risk of infections and cancer due to profound and prolonged immunosuppression. At the dosage authorised in multiple sclerosis, autoimmune disorders such as thyroid disorders and immune thrombocytopenic purpura are particularly frequent and serious. In practice, patients with multiple sclerosis already have difficulty coping with the troublesome consequences of their underlying disease. They should not be subjected to the serious adverse effects of alemtuzumab, especially given the absence of any proven benefit.

3. Aubagio and MS.  just a metabolite of leflunomide.
Clinical evaluation of teriflunomide is based on a comparative trial versus interferon beta-1a in 324 patients and on two placebo-controlled trials in a total of about 2300 patients lasting 1 to 2 years. In these trials, oral teriflunomide at a dose of 14 mg per day led to a statistically significant decrease in the average annual number of relapses compared to placebo, but teriflunomide may be less effective than interferon beta. No impact on the progression of disability has been shown during less than 2 years of follow-up. The burdensome adverse effect profile of teriflunomide is similar to that of leflunomide and includes hepatotoxicity, infections, leukopenia, arterial hypertension, peripheral neuropathy and alopecia. The long half-life of teriflunomide (about 19 days) complicates the management of its adverse effects and multiple drug interactions, and has important implications for patients wishing to have children. Teriflunomide is teratogenic in animals and should not be used by pregnant women. Fetal toxicity via semen cannot be ruled out. In practice, the adverse effects of teriflunomide in multiple sclerosis are disproportionate to its efficacy. It is better to choose interferon beta, despite its limitations.

Their April issue includes a paper called "Tecfidera and MS: Too many Long-term Unknowns

I'm thankful that the researchers of Prescrire are speaking out and publishing their findings.   But I wonder how many neurologists will heed their warnings and inform their patients?  While the MS drug machine continues to crank along, now making 20 billion dollars a year in profits, people with MS are rarely given the facts.  These new drugs are exceedingly dangerous, and they do not prevent disease progression. 

Please spread the word in your own community and help others understand the risks of these drugs are known, while the benefits remain unproven. 

Take care of yourselves and be well,
Joan

Oxidative Stress, MS and CCSVI


September 21, 2012 at 9:07am

We've just learned that one target of BG-12/Tecfidera, the new oral super drug /furniture fungicide, and Nrf2 activator from Biogen,  is oxidative stress.  This drug uses the Nrf2 pathway to combat oxidative stress.
link

What is oxidative stress, and how does it impact multiple sclerosis?

I first started reading about oxidative stress when I began researching the Endothelial Health program to help my husband Jeff.  I did this because his blood and body showed signs of oxidative stress.  The following info is from the program. 


+++++++++++++++++++++++++++++++++++++++++++++++

Oxidative stress
Our bodies constantly react with oxygen as we breathe and as our cells produce energy. However, our use of oxygen is a double-edged sword: we need oxygen to survive, but as a consequence of using oxygen, highly reactive molecules, known as “free radicals,” are produced. 

Free radicals are atoms or molecules with electrons which have lost their partner electron, often as a result of our respiratory or metabolic process, or from outside influences. Free radicals can disrupt the balance of nitric oxide, damage the endothelium and leave it overly permeable, allowing toxins to pass into our tissues9. 

In most instances, our body has an adequate supply of antioxidants obtained from food to neutralize these free radicals, but if the body is depleted, or if there are too many coexistent factors, injury to the endothelium and a change in the balance of NO may occur.

++++++++++++++++++++++++++++++++++++++++++++

People with MS have lower levels of antioxidants in their blood.  It's a scientific fact, pwMS have serious oxidative stress.

Oxidative stress in patients with multiple sclerosis.
We have investigated the oxidative stress in the blood (plasma, erythrocytes and lymphocytes) of 28 patients affected with multiple sclerosis (MS) and of 30 healthy age matched controls, by performing a multiparameter analysis of non-enzymatic and enzymatic antioxidants--

 In conclusion, the blood of patients with MS shows the signs of a significant oxidative stress. The possibility of counteracting it by antioxidant administration plus an appropriate diet, might represent a promising way of inhibiting the progression of the disease. 
Oxidative stress in multiple sclerosis
Accumulating data indicate that oxidative stress (OS) plays a major role in the pathogenesis of multiple sclerosis (MS). Reactive oxygen species (ROS), leading to OS, generated in excess primarily by macrophages, have been implicated as mediators of demyelization and axonal damage in MS. ROS cause damage to main cellular components such as lipids, proteins and nucleic acids (e.g., RNA, DNA), resulting in cell death by necrosis or apoptosis. In addition, weakened cellular antioxidant defense systems in the central nervous system (CNS) in MS, and its vulnerability to ROS effects may augmented damage. Thus, treatment with antioxidants might theoretically prevent propagation of tissue damage and improve both survival and neurological outcome. Central nervous system is particularly susceptible to ROS-induced damage due to the high oxygen demands of the brain and low concentration of endogenous antioxidants.
http://www.ncbi.nlm.nih.gov/pubmed/20120717


There are many more published papers on MS and oxidative stress, and all of the end with something to the effect of ---gosh, we really should have more studies done on how antioxidants help keep pwMS  healthy!  

But no one does these studies, because there is NO MONEY TO BE MADE!!  

You can simply go and eat more fresh fruits and vegetables, take some antioxidant supplements, vitamin D, stop smoking and drinking, exercise and take care of yourself.  
This is what I explained to Jeff when our family started doing the Endothelial Health Program together.  Dr. Terry Wahls, Dr. George Perlmutter and Dr. George Jelinek would tell you to do the same.  

Now---how does oxidative stress fit into the CCSVI scenario?  

Oxidative stress is actually found in all neurodegenerative disease---Alzheimer's, Parkinsons, MS and dementia.  These diseases share two things that contribute to oxidative stress:

1. Iron deposition in brain tissue
2. Hypoperfusion, or slowed blood flow through the brain.

So, we can see that pharma is figuring out there's more to MS treatment. They've seen the papers on CCSVI research, hypoperfusion, oxidative stress and gray matter atrophy.  But they will never tell you that in those words, because the want to keep selling you Tysabri, chemotherapies and other immune ablating drugs.  They will, however, figure out a way to sell you a pill that addresses oxidative stress.  

And you can bet your bottom dollar they are working on a drug to increase cerebral perfusion.

That's why we have to share this information, and help each other and those newly diagnosed with MS.  
Because there is hope, but there will be no miracle pill.
be well,
Joan
