'Day in the Life of ME' Awareness Feature

The purpose of this blog entry is to introduce a new feature the blog is trialling, named A Day in the Life of ME. This area is designed for raising awareness of ME/CFS online.  Stories, written by people with the disease from all over the world; will be published as regularly as they are submitted (within 24 hours).  One of the main focuses will be on individuals activities of daily living and how these are affected/adapted/managed with regard to ME/CFS.  Submissions are encouraged from individuals with ME/CFS as well as carers, significant others, friends, or medical practitioners (presented in the form of vignettes/case studies, with no identifying information).

Some points to consider for your submission:

What you did before you became sick with ME/CFS.
How long you've been sick with ME/CFS.
How ME/CFS affects you participating in your activities of daily living.
If you have family members who are also sick with ME/CFS, other autoimmune diseases, lymphomas, heart disease or Autism Spectrum Disorders
If you've tested positive for XMRV/MLV's, what does this mean for you?
What a cure would mean for you.

There are a number of ways in which this may pan out, it could remain a feature on this blog, or take on a life of it's own, depending on the response, of course.  But for now, the feature will be located at the top right of this blog page.  Remember, again, this is a public forum, once information is posted, cfsandxmrv.blogspot.com has no control over how that information is used, so keep yourself safe! Emails, addresses, last names, will not be published. Email your paragraph, (try to avoid it being too long, so as it fits in the feature space), to dayinthelifeofme@hotmail.com and lets help raise more awareness! 

Stories are already beginning to come in, and I've decided to post the first one here, as it's quite long, but absolutely amazing, beautiful and touching. 

A Day in the Life of ME, Amberlin.
1.  Things were really going along quite nicely. Normal as normal can get at the very least and oftentimes I would say things were much better than normal. I particularly loved my dog when I was a child and we'd explore the dry yellowed hilltops behind my house together.  Middle school was good. I had a best friend named Amber which was wonderfully uncanny. There really are few things in life that are as special as your best friend in 7th grade. That person knows absolutely everything about you and you do her and you never even are struck with the wondering if someone is going to be there to have your back or hear your story because you have a best friend who is all of that and more.
High school was mostly storybook. I was on the drill team and my boyfriend was the drum major not to mention an icon of apple pie. John Baker, with the blond hair, the blue eyes and the white picket fence to prove it. I got good grades, and school was easy enough.
College was amazing. I was surrounded by all of these incredible minds and kind hearts, silent snow falls and dance classes through the changing seasons. We took ice skating classes and camped in below freezing weather in the woods. Graduation came and then the exploration of career opportunities. I couldn't decide between doctor or dancer so I was doing a lot of both. I was in love with life.

2.It was one year after graduation when I was somehow approached by someone lugging behind them a hefty 2 foot by 2 foot box."I'm terribly sorry," I was informed,"but you will have to live in this box from now on."
While being very apologetic, this person made it absolutely clear that there were no other options. I left my backpack leaning up against a tree and stepped into the box. It was much too warm and much too small. I had to tuck my head down tightly for the lid to fit and then it was sealed, I was totally and completely sealed in. The disorientation was overwhelming. What was I doing in here? How was I going to make it to rehearsal and class? It was hot and I felt feverish. My legs and back began to cramp. The more I tried to move about, the more exhausted I became.
Slowly, I settled into a most fitful sleep. I'd had walking pneumonia previous to this life in a box and shortly after, my cough came back. I would cough all day and then through the night, my box a mess of robutussin and kleenex. I coughed so much I had to go to the emergency room. "Your rib is broken but there is not much we can do about that," is what the doctor told me. "As for the box, well, we don't address that sort of thing here."
I had no idea what that meant, except that I wasn't going to get any help. Meanwhile, living in this box wasn't what it sounds. It shuddered and shook like an angry beehive nearly all the time and had violent temperature fluctuations. I'd be sweating one moment and then visually turn blue with chill. It was as if it was tied to a roller coaster and I would cry out in pain from all of the diarrhea and nausea, which would, of course, just restart the coughing.  My parents were horrifically concerned. Why was I in there and who was going to get me out? Nobody seemed to hear our desperate pleas for help. Other people pretended that there was no box. They'd invite me salsa dancing and then say, "Oh, you're still not feeling well? Call me when you're better then." My heart beat out the words loneliness and despair.
I tried to keep my spirits up. I'd draw on the walls and continued to roll my ankles 50 times in each direction every day, so that they wouldn't be too de-conditioned when I was out of there and ready to get back to dancing. My ankles were always my weak point. I stopped doing that after about four years.
I learned to knit and crochet, sew and paint. I became very sensitive to light, so I'd often turn off the lights and choreograph in my head. The studio in my mind was huge and softly lit by the sun. I was a stronger dancer in that studio than I had ever been in any other. I spent a lot of time there.
And that was how it was for me, pressed in a box that was slightly smaller than I was. I lived there for about 6 years with the medical diagnosis: cramped lifestyle syndrome, not otherwise specified. We were in and out the doors of hundreds of doctors, healers, shamans, anyone who claimed they could do anything, practically. I could hear the whispers as we left the doctor offices , "She really needs to try harder. Perhaps she's trying to get attention or needs to see a psychiatrist." The alternative healers were telling me things like, "I think you may be dying." I wasn't sure which was worse.  I finally found a wonderful doctor who refused to give up. The first time I walked into her office she looked at me and said, "Good Lord, you are living in the tiniest box I have ever seen. You're not the only one, you know." I stared back at her, shocked. She tested me for everything. I did not test abnormal in any way, but my life was completely different in every way.

3.One day, there was the wheeze. It was around the 6 year mark that my marvelous doctor heard the tiniest of wheezes in my left lung. Off to the pulmonologist we went. He, too, noted the constraints of the box. "How is it that you are you surviving in there?" he asked. "I don't know if I am," I replied.
More tests. Finally, it came back that my lungs were as big as those of an Olympic swimmer, making my breathing tests look normal, but with the slightest contact with any kind of allergen, they would tighten up, hardly allowing me to breathe. Which allergens? The allergy doctor said that my entire back swelled up like a giant welt during the test. I was basically allergic to the planet, or at the very least, to most of California. I was put on the highest dosage of every allergy and asthma medication available.
Slower than a sloth, I began to feel a little more space in the box. I could untangle my legs just a bit and my brain didn't feel like it had quite so much lint in it all the time. I decided to take a class at a local graduate school. I would bring a pillow and curl up in the corner of the room. I often left class early or didn't go at all. If I got overtired the box would clamp down tight around me. My fever would soar and the pain and cramping were unbearable.
Over the next four years, the box gave me slowly enough space to work part-time, live on my own and take care of myself. I even started roller blading and jogging a bit. Jogging surprised me since I never liked to jog. So why did I do it? Because I could, and every time I did, it felt like a miracle was taking place. As long as I remained hyper-vigilant of the space I was allowed, I did all right. If I tried for more room, say a dance class or something, the box would shrink up and seal me in its cement cage. I learned the rules and ways of that box in such strategic detail, that I was able to travel alone, and so I did that, too. It wouldn't tolerate crossing time zones, so I traveled my skinny strip of the planet and learned Spanish, which was the gateway into the beautiful and bright world of Latin America. I fell in love with Ecuadorian food, the coast of Costa Rica, and even a Mexican man.

4.In 2007, 12 years after the kick off of my illness the relapse began. In the six years that I had been granted a bit more space, I had finished graduate school, bought a house, become a licensed therapist, was working in the schools and running a private practice. Perhaps, it was too much. Maybe it was the stress of moving. No one will ever know, but three weeks into working with the high school I called in sick and never went back. This time, the box shrunk in tighter than a shoe box.
I had migraines that spanned days on end. I couldn't tolerate and kind of sensory stimulus and so I lived in silent, painful, darkness. My mind was so clouded I couldn't remember which line was for my name on a check. Sometimes, I was too tired to pee or roll over. I had diarrhea for 18 months straight. I woke up every morning feeling that I had been electrocuted and beaten by clubs.
...I can't write anymore. The thought of it catches my breath. All I can say is that things got infinitely worse. Worse than anything I could ever have imagined. The hospital has become my second home, and the illness rages on in this body.   We're too close to now at this point and I don't know how to write about now. Maybe in five years or so, I can tell that story. So, this is where I'll have to stop for the time being. I guess that what keeps the story short.

I Hope You Dance fundraiser gala

The Whittemore Peterson Institute's annual fundraiser gala, I Hope You Dance, was held on 10 September 2010.  During this event, three new promotional videos for the Whittemore Peterson Institute were played for the audience.

During the gala, Andrea Whittemore-Goad presented Heidi Dunlap Bauer with the title of Outstanding Patient Advocate. Heidi has done outstanding work over the past year in promoting awareness of ME/CFS, educating around the plight of patients worldwide, while maintaing family life and managing her own ME/CFS.

Here is a video of Heidi's moving acceptence sppeech (Thank-you to Jenni Saake).

Q&A from the First International XMRV Conference

On the 07 and 08 of September 2010, the first international XMRV conference took place at the National Institutes of Health.  Watching the conference Q&A videos (listed below), and reading the transcripts, one can feel the almost combatative tensions between the scientists who had identified a correlation between ME/CFS and XMRV, and those who argue that this potential link could be explained by murine contamination of the equipment used in the respective experiments.
The Q&A was moderated by Dr Jonathan Stoye, Virologist, whom didn't appear to have a great deal of control over the conference proceedings. Dr Stoyle did, however, verify Kirsten White's (Gilead Sciences) comment, which remains somewhat unanswered:

"My question is about the different clades of potentially human pathogenic XMRV’s.  We heard about the X and the P, and I was hoping you could summarize, are there four we’re looking at, are there two, are there three, and what we should call them?'.

Mindy Kitei (of CFS Central) represented patients by asking more practical questions, such as  when drug trials will commence; what drugs are likely candidates; and what sort of timeframe this may occur in.  Mindy went on to challenge Dr Stoye later during the Q&A, suggesting that although it was understood drug trials were premature, scientists were seeking what they want to seek with regard to the absence of XMRV in certian experiements.  Mindy continued, stating it was importat for scientists to 'really see things as they are and not how we want them to be'.  Dr Coffin demonstrated why it was premature to begin drug trials, although it is something to work towards.

There was a tense exchange between Dr Mikovits (Whittemore Petersone Institute) and Dr (Proffessor) McClure (Imperial College in London), with Dr McClure disagreeing outright with Mikovitz, about finding positive samples in the UK.  Dr Mikovitz responded:

"I had at least 50 positives right from the London area and many more besides that using the techniques that we validated in our paper and clinically and that have been used throughout this room.".

Dr McClure stated she was now 'happy' to recieve positive samples, transported via independent phlebotomy services.

Summary of Meeting with Patients and NIH Officials

On the 07 September 2010, prior to the commencement of the First International Workshop on XMRV, nine people with ME/CFS, and their families, met with highly regarded officials from the National Institutes of Health.  It appears that this is the first time such a meeting has taken place.

The officials from the NIH included:

Michael Gottesman, M.D.    Dr Gottesman is the chief of NCI's Laboratory of Cell Biology and Director of the NIH Office of Intramural Research.  Michael is known for identifying the human gene responsible for resistance of cancer cells to many of the most common anticancer drugs.

Paul Holtz, M.D.  Dr Holtz is the chief of the Arthritis and Rheumatism Branch at NIH. Paul is interested in myositis and other muscle diseases, including Pompe Syndrome, which continues to dominate his interest.

Roland Owens, Ph.D  Dr Owens is the Assistant Director of the NIH Office of Intramural Research and he is also chief of the Molecular Biology section in the Laboratory of Molecular and Cellular Biology in the National Institute of Diabetes and Digestive and Kidney Diseases at NIH.  Dr. Owens is a co-inventor on two patents involving AAV gene therapy applications.

The meeting was organized by ME/CFS patient Robert Miller.  Robert opened the session, which was originally scheduled for 30 minutes, but went for 1 hour, with his own testimony, which highlighted the two key issues which the majority of people with ME/CFS identify; the fostering of trust between patients and the medical community, and the need for more funding in the area of ME/CFS research.

During the question and answer period, Dr Gottesman explained that his department received 10% of the funding that was issued to the NIH.  The Office of Intramural Research was where internal research within the NIH took place, and that the associated funding was used to complete what he termed as 'higher risk' research.

It was discussed how patients were already looking at options for antiretroviral treatment and were on these drugs due to desperation.  Gottesman reiterated how dangerous it is for individuals to investigate and try antiretrovirals as clinical trials have yet to take place.

According to Rivika Solomon, who shared a transcript of the meeting, (link below), Patients and NIH officials plan to meet again in three months. If anyone has further information regarding this meeting, please don't hesitate to add comments, links or notes below.

Request for a post

Thanks to those who have sent messages and emails through this morning; I didn't really think to post here, but I got a few requests, so I'll briefly note what I know, but I suggest people check Google or TVNZ, for more accurate information.

I live In Dunedin, New Zealand, almost 300 kilometers south of Christchurch. At 4.35 am this morning, we were awoken by a rather large (7.1 - downgraded from 7.4) magnitude earthquake (I was stuck in bed as it usually takes me half an hour to get up in the mornings, as my back and legs seize up - combination of ME and cerebral palsy) which seemed to go for about 10 minutes. TV says it went for closer to 15 minutes.

My father, step-family, best mates, Saul's extended family, all live around Chch, and are getting aftershocks every 20 minutes. A state of emergency was put in place just a wee while back. Up there, the Central Business District is closed and currently being evacuated with severe damage; water mains are busted, sewage pipes have ruptured in some towns and suburbs, roads have been badly damaged, as have houses, vehicles, businesses, some TV stations are not reporting, as they're buggered. Cell phone towers are on reserve battery, which is running low. Landlines and internet are down, and flooding in some suburbs from burst pipes. Massive cracks in the ground with parts of earth risen, or fallen, .

Many people are isolated in their own homes, but apparently welfare stations are being set up in the suburbs.  The imminent concerns are water safety (due to sewage etc) and infrastructure stability. There are only a couple of people with serious injury, and no reported fatalities.  Watching the news, all the support services look to be working really smoothly together, there doesn't appear to be anyone panicking; and the news isn't being sensationalist or anything.

Thanks again for people concern, our thoughts are with those in and around Christchuch.

Not just XMRV anymore.

In October, 2009, a paper by Lombardi, V., et al., ‘Detection of an Infectious Retrovirus, XMRV, in Blood Cells of Patients with Chronic Fatigue Syndrome’ was published in a leading   research journal, ‘Science’. This paper demonstrated evidence that a Murine Leukemia Virus (MLV) species, XMRV, was associated with ME/CFS in some (yet to be determined) manner, with the results showing the virus was present in 95% of CFS patient samples (Lombardi, V., et al., 2009).  This study also found that the XMRV virus was present in 4% of the healthy control samples (Lombardi, V., et al., 2009).

In January 2010, a paper by a group of UK scientists, from both the Faculty of Medicine of the Imperial College and Department of Psychological Medicine, Institute of Psychiatry, Kings College, published findings that failed to identify any association between XMRV and ME/CFS (Earlwin, et al,. 2010). This paper, Failure to Detect the Novel Retrovirus XMRV in Chronic Fatigue Syndrome, was published in the Public Library of Science, is discussed briefly in the blog entry dated 07 January 2010. 

In February 2010, another study came out of the UK, which again failed to find an association between XMRV and ME/CFS.  The findings of the Groom, H., et al (2010) paper, Absence of xenotropic murine leukemia virus-related virus in UK patients with chronic fatigue syndrome, were published in the journal Retrovirology.  The results of this paper are discussed in the blog entries dated 20 February 2010 and 25 April, 2010.
In the Netherlands, Kupperfield, F., et al (2010), published ‘Prevalence of xenotropic murine leukemia virus-related virus in patients with chronic fatigue syndrome in the Netherlands: retrospective analysis of samples from an established cohort’ in the British Medical Journal.  Again, this study failed to identify XMRV in the CFS samples used in the research (Kupperfield, F., et al. 2010).

Increasingly, during the period of time since the publication of the Lombardi, V., et al., (2009) paper, patients, families, carers, medical professionals, researchers, have debated the possibilities for such conflicting results.  Judy Mikovits at the WPI, stated that XMRV was notoriously hard to find, stating that the virus is
'...in too low a copy number in the genomic DNA (that is the provirus..integrated into the cells DNA) ..there may be less than 10 copies of provirus in 10 million cells..so unless you amplify the 1 microgram of genomic DNA from uncultured cells you might miss it' (Johnson, C., 2010).

Further to this, press releases from the Whittemore Peterson Institute detailed differences in the way the experiments were carried out which demonstrated why these studies were not true replications of the Lombardi, V., et al., (2009) study.  The Whittemore Peterson Institute sent a letter specifically to Dr Myra McClure, of the Earlwin, O., et al (2010) paper, suggesting that differing techniques and equipment were being used, as well as ME/CFS sample cohorts defined by criteria different to that which the Whittemore Peterson Institute used.  A discussion of this is available in the blog entry posted 20 Feburary, 2010.

On the 22 of June, 2010, a press release was published which stated that a combined team of scientists from the Food and Drug Administration, (FDA) and the National Institutes of Health, (NIH), had completed a replication of the Lombardi, V., et al., (2009) study, which not only confirmed the original findings, but expanded on them. It was soon announced, however, that due to conflicting results with a paper published by the CDC, a halt was placed on the Lo, S., et al (2010) publication.  Again, debate about the studies was further fuelled by involved parties; researchers, patients, doctors, and support organisations.

At 7am, New Zealand time, on August 24, the press embargo was lifted, and the Lo, S., et al (2010) paper was finally available online.

Lo, S., et al (2010) used 37 whole-blood and serum samples which had been collected from individuals with ME/CFS in the mid 1990's.   Lo, S., et al (2010)  also obtained repeat blood samples from 12 of the initial 37 patients; 4 of which were collected two years after the first samples were taken, and the remaining 8 were collected again in 2010.  Alongside this, blood samples were collected from 44 healthy controls.  Lo, S., et al (2010) reported that they used nested PCR techniques to target the gag gene of any XMRV DNA sequences present, as well as other MLV-like DNA.

The results of the Lo, S., et al (2010) demonstrated that 32 of 37 (86.5%) samples from ME/CFS patients revealed positive amplification of MLV-like viral gene sequences in the nested PCR, compared with  3 of 44 (6.8%) volunteer blood donors.  On testing of the 8 repeat samples collected in 2010, 7 remained positive, although all 8 reportedly remain symptomatic. 

In reading the results and discussion of the Lo, S., et al (2010) paper, one thing becomes glaringly obvious.  The results fail to report any specific findings of XMRV, that mouse virus variation which many people have taken great pains to undertsand over the past several months.  Instead, Lo, S., et al (2010) reports finding MLV's, (Murine Leukemia Viruses), which are a genus of gamma retroviruses, of which, XMRV is a species.  In fact, Lo, S., et al (2010) identified 4 variations of MLV's, not all of them xenotropic (warranting the XMRV label).  Judy Mikovits reports presenting a paper at the Cold Spring Harbor RNA tumor virus meeting in May 2010 demonstrating samples in the Lombardi, V. et al (2009) paper had Xenotropic (as in XMRV) and polytropic MLV variants as well as at least one more variant.  (Ketei, M., 2010). Furthermore, in comparing the 8 samples collected in 2010 with samples collected from the same 8 individuals with ME/CFS 15 years ago, it was apparent that the MLV had gone through significant mutation (Lo, S., et al. 2010).  “That’s just what you’d expect from a retrovirus,” said Alter. “That’s more evidence that this is a real agent, not a sequence floating around in the lab.” (Ketei, M., 2010).

Aside from the different variations of MLV identified in the Lo, S., et al (2010) publication, is the startling evidence that almost 7% of the controls, all of whom are blood donors, tested positive for these MLV variants.  This is indicative that these variations of MLV's are likely in the public blood supply, at least in the USA, where the samples were taken.  Mindy Kitei, of CFS Central, reports that Harvey Alter is commencing studies to determine if the MLVs identified in the Lo, S., et al (2010) paper, are potentially transmitted by blood (Ketei, M., 2010).

It is important to state that at this stage, there is not sufficient evidence to suggest MLV's are causative or co-morbid pathologies to ME/CFS.

News of the publication of the long awaited Lo, S., et al (2010) paper spread quickly across the internet, with discussions, blog posts, news articles and opinions being printed and reprinted through social mediums such as facebook.  It appears, however, that in some areas of the world, namely the UK, the news has been much slower off the press. Andrea Pring, writer and fellow ME/CFS patient, reports on her blog, Dancing with the Sandman, some of the contextual factors possibly contributing to the lack of news coverage in the UK, including the involvement of Professor Simon Wessley in the advisory panel of the Science Media Centre (Pring, A., 2010).  For further detail on this, please read Andreas blog post titled 'The Truth Behind the Headlines (August 29, 2010).

I would now like to take this opportunity to print a public thank-you to all the researchers, medical professionals, advocates, organisations, carers, families and supporters who have worked tirelessly over the decades, in the search for explainations and answers to this illness. It is far from over; the exploration continues, but we can be graterful of the advance in knowledge of this disease that has been made in the past few months.

Specifically, I woould like to thank Annette and Andrea Whittemore; Annette, in her quest as a mother to give her daughter the opportunity of quality of life and improved health, has given hope of a greater quality of life and health to all sufferers of ME/CFS across the globe.  And Andrea, in advocating for her own health, as well as advocating for the work of the Whittemore Peterson Institute, has given a voice to all ME/CFS patients, worldwide.  For this, we thank you both.

Alter Paper

I am unable to write the commentary on this that I am so desperate to post, however, here are some of the key links I've had a look at over the past few days.

I will return to this, as my health allows, and discuss it, as I've done previously. If only for my own and my families benefit.

I encourage people to contribute to this list, and to discuss their interpretations and what it means for them, for us and for the rest of the world. 

There are challenges already with getting the news out about this finding, and suggest that if you live in an area where you don't feel there is adequate coverage of these groundbreaking findings, inform your local news agencies, educate your government representatives, print off copies of the paper and take it to your GP.

As I stated, I would like the opportunity to discuss this paper, specifically the science, and hopefully in a few days, the opportunity will arise.  There are going to be all sorts of aspects to this scientific development, political, social, and historical.  Not being from the UK or USA, I don't feel well enough informed to address some of these adequately on my own, so I do welcome any contributions, particularly in the political and historical areas.

XMRV name change: the benefits and detriments.

There is a blog entry dated 29 December 2009, which addresses, very briefly, the names ME, CFS, Post Viral Fatigue, and so  forth.  it is beneficial for people to have a read of that entry, and it's attached links, as a background to this entry.  However, this entry discusses the proposed change from XMRV to HGRV, and HGRAD.

For the first time on this blog, apart from the blog entry about my personal story (dated 28 December, 2009), the  information discussed will be somewhat more subjective than usual, because of the nature of the discussion, and my own  interest and understanding of it.  What is presented here, therefore, are my own opinions, and must be interpreted as only  that.  People will not always agree with each others opinions and views, no more so mine than anyone elses, but I do ask that  people take time to read and understand the rationale behind such opinions, and use that to further develop their own ideas and values, whether in agreement or disagreement.

On 19 August 2010, a notice began circulating on ME/CFS websites and blogs from Rich Van Konynenburg, PhD, on behalf of Dr. Burrascano, MD, who attended the first official XMRV symposium of the Whittemore-Peterson Institute (Prohealth, 2010). The notice states firstly that a working group has been established to regularly meet and appraise the developments around what we are currently referring to as XMRV and it's association with ME/CFS.  The notice goes on to report that a new name has been proposed for XMRV and it's association with ME/CFS, and this announcement is expected to be made at the NIH retroviral conference this September Institute (Prohealth, 2010).  Reflecting on this, provides a good opportunity to reflect on the XMRV label, how it has been used, and  the benefits, detriments of changing this.

XMRV or Xenotrophic Murine virus-Related Virus, has been been used in ME/CFS circles since the news broke in October 2009 that a possible link had been identified between it and ME/CFS.  Before that, it had been identified in 2006 as potentially involved with both hereditary and spontaneous prostate cancer (Schlaberg R., et al. 2009). The name Xenotrophic Murine virus-Related Virus tells us that this virus that the WPI connected with ME/CFS in October 2009 is related to a retrovirus that originates from mice.  It does not cause disease in it's original hosts (the mice), but once it is transferred to another species, say humans, and inserted into their DNA genome, it can code for a provirus, which causes either active or latent infection (Belshaw, R., et al. 2004).  For further information on this replication process, have a look at the entry dated 28 December, 2009).

The new name proposed for what we are currently calling XMRV is Human Gamma Retrovirus (HGRV), and for the consequential symptoms and disease pathology, Human Gamma Retrovirus Associated Disease (HDRAD).  This would suggest that the signs and symptoms people experience as a result of the infection, would be referred to as HGRAD.  This would indicate, assuming that XMRV, or HGRV is causative to ME/CFS, that people who currently have a diagnosis of ME/CFS will therefore have a diagnosis of HGRAD, a disease process associated with the Human Gamma Retrovirus.

There are a number of thoughts and perspectives on this proposed change of name.  Of course,  it hasn't even been one year since the WPI announced their XMRV findings, people with ME/CFS are still getting used to the possible XMRV connection and label.  This disease already has a number of different names attached to it, and to have yet another name added to the list, is going to cause confusion.  Especially so because people have already started using the term XMRV for educational and promotional purposes.  Another reason is that this is yet another opportunity for the CDC and the Wessley subscribers to to continue to deny that ME/CFS is pathophysiological disease process, and promote their CBT and GET therapies.

However, and this next part is my own opinion, feel free to challenge it.  The label XMRV never differentiated between the infections that it had potentially been linked to; prostate cancer and ME/CFS.  It fails to acknowledge this retrovirus as the first gamma retrovirus known to infect humans, which is the genus that differentiates it from HIV.  In terms of a medically terminological label, HGRV, is a much more accurate informative and accurate label for the retrovirus known currently as XMRV.  Yes, the retrovirus is still related to xenotropic murine virus, but that isn't clinically relevant in the infection process, or treatment of prostate cancer or ME/CFS. 

HGRV highlights that this is a (the first) gamma retrovirus discovered that effects humans, and HGRAD allows the flexibility for it to be used to cover various disease processes caused by the retrovirus; namely prostate cancer and ME/CFS currently.  There will need to be work done in terms of education and promotion that ME/CFS is one and the same as HGRAD for those who test positive for the disease.  As we would for any new name given to the disease.  People must to continue to advocate for acknowledgment from those organizations who have mistreated and misrepresented people with this illness, and ensure that a change of name does not negate it's history of management.  In the meantime, we are still awaiting evidence of whether this retrovirus is causative of, or co-morbid to ME/CFS, evidence which hopefully will come out shortly in the form of a science paper published in the Journal of the Proceedings for the National Academy of Sciences.

The Echos of Silencing Science

Science is beginning to verify the fact that my body isn't so well.  That my DNA, and that of a couple of my family members, is possibly ravaged by a retrovirus.  Politics is telling me that I needn't waste my time on such nonsense, and that this isn't an issue I should dwell upon.

On 06 July, a blog entry titled FDA/NIH Paper in Limbo; Patients Unite, authored by freelance science reporter Mindy Kitei on her blogsite CFS Central, (see link on right of screen), is published, suggesting that the NIH/FDA paper was in fact halted by high level government officials in the Department of Health and Human Services (Kitei, M., 2010).

Kitei. M., (2010), reports that Dr Steve Monroe of the High Consequence Pathogens and Pathology at the CDC stated that "When CDC, FDA, and NIH learned that separate studies had been conducted with differing results, a collective decision was made to try and account for these differences.”.  Marcus, A. D., (2010) reported similarly on the halted papers, quoting editor-in-chief Kuan-Teh Jeang, of the journal Retrovirology, as saying "My understanding was HHS [Department of Health and Human Services] wanted to get it straightened out. Both reports are from different branches of the government," (Marcus, A. D., 2010).  

Since then, however, it hes been reported by Kitei. M., (2010), that the CDC is responsible for halting the NIH/FDA Paper.   'Sources have told CFS Central that higher-ups in the Department of Health and Human Services (HHS) made the ultimate decision to hold up the study.' Kitei. M., (2010).  Kitei. M., (2010) goes on to state that the FDA/NIH paper was in final proofs when it was halted.

This, no doubt, will cause much angst among the ME/CFS community of patients and advocates, as it had been leaked that the FDA/NIH paper had found a positive correlation between ME/CFS and XMRV, and further addressed the issue of public blood supply infection.  The positive findings of the NIH/FDA paper will be some of the first which verify the findings of the Whittemore Peterson Institute.

I'm not sure about anyone else, but I prefer the sound of science, to politics.

Science vs Silence

The previous blog entry, dated 25 June, discussed a press release which indicated that a research team, headed by a Harvey Alter, a medical researcher, virologist, physician, and chief of the infectious disease centre at the National Institute of Health, had submitted for publication the results of a study into the incidence of XMRV in blood samples taken from individuals with ME/CFS.  Dr Alter reportedly stated that the findings of this study, to be published in the journal Proceedings of the National Academy of Sciences of the USA (PNAS), reinforced the findings of the Whittmore Peterson Institute in identifying the Gammaretrovirus XMRV in blood samples of individuals with ME/CFS. For further detail about this release, refer to the previous blog entry.

Five days later, on 30 June, it was reported in several publications that the Centers for Disease Control had also completed a study into the incidence of XMRV in ME/CFS.  Their results, however, failed to find XMRV in blood samples taken from individuals with 'Chronic Fatigue Syndrome'.  Two different government agencies; two different results. So each publication, respectively, went on hold.

Ashley Truxon, media coordinator for the journal Proceedings of the National Academy of Sciences of the United States of America, (PNAS), stated that the paper submitted for publication by the FDA/NIH had been placed on hold, with no further comment (Marcus, A. D., 2010).  Meanwhile, editor-in-chief Kuan-Teh Jeang, of the journal Retrovirology, stated that the paper submitted by the CDC had been through the peer-review process, and had been accepted for publication, however, Dr. Jeang received a call from the authors of the paper, requesting be held.  "My understanding was HHS [Department of Health and Human Services] wanted to get it straightened out. Both reports are from different branches of the government," Dr. Jeang said (Marcus, A. D., 2010).  

In the process of scientific discovery, publication of scientific results is an integral part of the scientific method.  To be published, a paper must endure significant peer review, and provide substantial detail enabling the research to be repeated by independent researchers.  The pursuit of scientific inquiry requires that research submitted for publication by a journal meets rigorous criteria, in order for it to be published, and a part of scientific record.  As such, although it isn't unheard of for submissions to be halted after the peer-review process, it is highly unusual.

24 hours later, on 01 July, and the journal Retrovirology goes ahead with it's publishing of the Switzer, W. M., et al paper, 'Absence of evidence of Xenotropic Murine Leukemia Virus-related virus infection in persons with Chronic Fatigue Syndrome and healthy controls in the United States'.  A discussion of this paper will be attempted in a future blog entry. 

Meanwhile, we are left wondering what happened to the NIH/FDA paper.  Kaiser. J., (2010) reports that the authors of the PNAS paper have decided it needs more work. NIH spokesperson John Burklow explained to Insider that the paper had been accepted by the journal PNAS, but Alter and his co-authors decided to "pull it back" and revise it in response to questions raised by reviewers (Kaiser. J., 2010).  Harvey Alter of the NIH Clinical Center, Stated on 30 June "Our paper has not yet been accepted for publication. My colleagues and I are conducting additional experiments to ensure that the data are accurate and complete. Our goal is not speed, but scientific accuracy."

As of the printing of this blog entry, the NIH/FDA paper has yet to be published.

Again, a future blog entry will discuss the paper published by the CDC in the journal Retrovirology, however, in the meantime, I have included a link to a statement made by the Whittemore Peterson Institute in response to the reported findings.  I have also added a link to a discussion written by Andrea Martell, of the Blue Ribbon Campaign for ME.  Also included is a link to the facebook page, XMRV Press releases.

The topography of scientific enquiry, Part Three

"We (FDA & NIH) have independently confirmed the Lombardi group [which published the original Science paper] findings.”  Harvey Alter, chief of the Infectious Disease Department, NIH.

“It’s what we’ve been waiting for" Annette Whittemore, of the Whittemore Peterson Institute.

The publication of a paper in the Journal 'Science', in October 2009, brought about an excited and hopeful response from ME/CFS patients worldwide - even here in New Zealand. Initial research, conducted at the Whittemore Peterson Institute, by a team of retrovirologists, indicated that a retrovirus, XMRV (Xenotropic Murine leukaemia virus-Related Virus) was present in initially 67% of ME/CFS patient blood samples. Subsequent studies by the same researchers, Lombardi, et al., eventually identified the virus in 95% of CFS patient samples.  After decades of lack of treatment, no diagnostic criteria, and apathy and dismissal from the medical community, this was
the moment that few of us had dared to hope for. 

In the past several months since the Lombardi, et al. paper was published, a number of supposed replication studies have been conducted which have challenged the findings of the WPI.  As discussed in the previous blog entries titled 'Topography of scientific enquiry', and 'Topography of scientific enquiry - part two', in response to any new avenue of research, the scientific community has a responsibility to replicate and correlate the results, in order to validate the initial hypothesis and consequent findings.  In this case, there was a responsibility to acquire a cohort of well-defined ME/CFS-positive blood samples, test them for XMRV, and establish if the WPI were plucking at straws, or had indeed really identified something big.  This replication process requires an accurate understanding and implementation of the same techniques, protocols and procedures used by Lombardi, et al., and equally importantly, to have a motive towards understanding the medical mystery which is ME/CFS

Right form the outset, the stakes have been high for everyone involved, careers have been built on the establishment of ME/CFS as a psychosomatism, or Neuralgia, plenty of money has been withheld in the form of benefits for those who cannot work, children have been sectioned, individuals have been put through detrimental graded exercise programs, and worst of all, lives have been lost.  So when the initial, so-called replication study, published in PLoS, came back negative, it wasn't surprising to the patient/advocate community, nor did it contribute any further scientific insight, or hypothesis, to the understanding of ME/CFS.  Instead, what has since followed in the past few months, has been a rather public controversy.  Judy Mikovits, research scientist at WPI suggested that XMRV is unusually difficult to find, McClure, et al., responded that it was their belief that the discrepancies in their published findings indicated a different pathology of the disease in the UK, from that which was in the USA. It was suggested that the samples and/or equipment, used by the WPI was contaminated, WPI publicly offered to send some XMRV-positive samples to the UK, and so on and so on. Meanwhile, ME/CFS patients and advocacy groups, continued to wait, watch and hope.

As of 22 June, 2010, it seems that the exact thing we are waiting, watching and hoping for is about to be officially published.  A press release, dated 22 June 2010, states that  Harvey Alter, a medical researcher, virologist, physician, and chief of the infectious disease centre at the National Institute of Health, made a presentation on blood supply, in May 2010.  Alter made a slide show presentation which addressed potential contamination of the blood supply, and protecting the supply from disease.  The presentation was made in Zagreb, to select individuals, and included a slide that referred to the XMRV-CFS association as "extremely strong and likely true, despite the controversy" (Marcus, 2010).  The slide went on to state that the connection between XMRV and ME/CFS “is very strong, but causality not proved.”.  Furthermore, Alter and his research team estimate XMRV and related viruses to be present in three to seven percent of blood donors, in comparison to the four percent cited in the Lombardi, et al. paper.  At the end of the slide, was the statement “We (FDA & NIH) have independently confirmed the Lombardi group [which published the original Science paper] findings.” (Marcus, 2010). A spokesperson for the NIH has confirmed the authenticity of this presentation, however, there has been no further formal comment or release from the NIH, and Alter himself has made no comment, except to confirm the paper containing this data is to be published soon.

Error Preceeds Truth

 'In all science, error precedes truth, and it is better that it goes first than last' Hugh Walpole

Previous blog entries over the past three or four months, both here and elsewhere, have called upon science to prevail in the endeavor to further identify and understand any correlation between XMRV and ME/CFS.  The blog entry titled 'The Topography of Scientific Inquiry' and 'The Topography of Scientific Inquiry - Part 2' address the necessity of producing replication studies when a new scientific discovery is made, for the purposes of verification.

At this stage of the game, there continues to be dispute over the findings of the original paper published by scientists at the Whittemore Peterson Institute, National Cancer Institute and Cleavland Clinic.  There is a lot at stake, after all.  Money is always a factor, careers will potentially be made or destroyed in the research field, medical arena and even in the journalism profession, based on who covers the story and what bias they take. Insurance companies stand to increase payouts, and at the very center of the debate, the quality of life for those individuals who have a diagnosis of ME/CFS, could be set to improve. Dramatically.

In January 2010, in response to the initial study published by the Whittemore Peterson Institute, McClure, et al published research they had conducted which failed to replicate the results published by the Whittemore Peterson Institute. It has since, however, become increasingly apparent that the McClure et al study failed to replicate the initial Whittemore Peterson Institute study. This also appears true of two further studies, including one published in the Netherlands by Van Kuppeveld et al, which also published a failure to detect XMRV in individuals with a diagnosis of ME/CFS.  Since these publications, the Whittemore Peterson Institute have produced press releases which suggest reasons why none of these studies can be deemed as replications, due to the use of different equipment, different procedures, different cohorts.

But what about if these UK studies did find evidence of XMRV in their ME/CFS cohorts?

'We would also like to report that WPI researchers have previously detected XMRV in
patient samples from both Dr. Kerr’s and Dr. van Kuppeveld’s cohorts prior to the
completion of their own studies, as they requested. We have email communication that
confirms both doctors were aware of these findings before publishing their negative
papers. In addition, Dr. van Kuppeveld asked for and received reagents and a positive
patient sample to determine if his testing procedures could in fact detect XMRV in a
positive blood sample before he published his paper. We wonder why these materials
were not used in his study which also failed to detect XMRV.'(Whittemore Peterson Institute, 2010).

'The negative studies were technically flawed in that their methods were demonstrated NOT to be capable
of detecting XMRV. Their patient populations likely did not satisfy CCC criteria and they looked only by PCR on genomic DNA the least sensitive way of detecting XMRV. To date none one has attempted to replicate our study. It is very clear that the prevalence of XMRV in UK is NOT ZERO and that XMRV has been detected in CFS patients in the UK. (Whittemore Peterson Institute, 2010).

Meanwhile, we are beginning to see the emergence of the initial findings of the Whittemore Peterson Institute into the mainstream.

We are now reading about bans being put in place on blood from donors who have or who have had diagnosis of ME/CFS. Please refer to the blog entry dated April 23 2010, 'A Question of Blood'.

A study published in the Journal of Virology, titled: Inhibition of Xenotropic Murine Leukemia Virus-Related Virus by APOBEC3 Proteins and Antiviral Drugs, indicates that the use of antiretroviral drugs such as Tenofovir, AZT and Raltegravir, currently used in the management of HIV, would possibly be effective against XMRV infection (Paprotka T, 2010).

The pharmacutical company, Glaxo Smith Kline, has announced that they are funding a replication study that will attempt to replicate the Whittemore Peterson Institute's XMRV findings.  “Ethics board approval is pending, but we expect this study to begin shortly. GSK will obtain specimens for this study from [patients diagnosed by] Hunter-Hopkins Center (Charlotte, NC) as well as Drs. Klimas (Miami), Bateman (Salt Lake) and Gluckman  (Philadelphia) in order to sample subjects from diverse geographic locations. Samples will be provided anonymously by the new SolveCFS BioBank, recently funded by the CFIDS Association…” (Prohealth, 2010).

A question of blood.

It has been a while since the last blog entry, not due to lack of developments and newsworthy events in the ME/CFS and XMRV arena, however.

This month has so far seen the beginning stages of a reaction by public health officials to the Whittemore Peterson Institute research findings of October 2009, in which a retrovirus, XMRV, was identified as having a potential connection with the disease process of ME/CFS. Of course, many of us have since witnessed the follow up studies carried out in Europe which have failed to replicate these findings, however please see earlier blog entries regarding the reasons why these fail to contend as replication studies.

Up until this point, people with a diagnosis of ME/CFS have not faced great scrutiny, at least in New Zealand, with regards to donating blood.  Granted, during an ME/CFS relapse, the majority of individuals, due to the symptoms of the disease, may choose, understandably, not to donate blood.  Some may be advised by members of their respective medical team, not to give blood, on account of the potential further detriment to health and wellbeing.  

This makes a lot of sense, because there is notable evidence to say that individuals with ME/CFS have a reduced circulating blood volume compared to healthy controls (Bell, s., 2000), which would obviously be further reduced by the donation of blood.  Specifically, one of the signs associated with a diagnosis of ME/CFS, Postural Orthostatic Intolerance (low blood pressure upon transfer from lying to sitting, sitting to standing etc) would be further exacerbated by giving blood. Some individuals with ME/CFS have difficulty even with blood draws for testing, let alone a full donation. (Please refer to the Canadian consensus document, and the links at the end of this entry,for further information specific to Orthostatic Intolerance).

At the end of the day, despite the detriment to the health of these individuals, up until now, individuals who have, or who have had, a diagnosis of ME/CFS have not been rejected specifically for the purpose of public safety because of their illness status.  This, we can now see, is beginning to change. In Canada, earlier this month, a lifetime ban was placed on any individual who had a past or present diagnosis of ME/CFS (Toronto Sun, April 07 2010). This was followed soon after by New Zealand (Stuff.co.nz, April 21), and blood donor policy is currently under review in Australia with regards to ME/CFS.  These moves appear to have been instigated by the findings published in the Science Journal in October 2009, which identify a potential link between XMRV and ME/CFS.

At this stage, both Canadian and New Zealand authorities are stating that this is a precautionary measure, we still don't have that replication study of the the initial research conducted at the Whittemore Peterson Institute.  However, if XMRV does have a role to play in ME/CFS, then the hypothesis of transmission of the retrovirus by the Whittemore Peterson Institute, is that 'XMRV is thought to be transmitted through body fluids such as blood, semen, and mother’s breast milk but is not transmitted through the air. (It is not known whether XMRV is more easily transmitted than other human retroviruses).' Whittemore Peterson Institute, 2010.
It shall certainly be interesting to see if the moves made so far by both the Canadian and New Zealand Public Health authorities, begin a domino effect, and increased perseverance by the medical community to act on the findings of the Whittemore Peterson Institute, and follow up with some replication studies.

On another note, I am planning to write a blog entry on the letter sent by the Whittemore Peterson Institute addressing the McClure et al study, which failed to identify XMRV in individuals with ME/CFS. In the meantime, I have put a link up to the letter itself.

Topography of Scientific Inquiry, Part 2

It may be beneficial for some to have a look at the blog entry dated 7th January, 2010, which was a short analysis of the study published in PLoS, and the requirement, within scientific endeavor, to replicate studies.

This blog entry, once again, is an update and discussion around the latest research paper regarding the presence of XMRV in individuals with ME/CFS to come our of the UK. The aim is to provide factual information about the study and the response from the WPI, who first iderntified XMRV in relation to ME/CFS. The purpose is to generate discussions around this disease process, to further educate others and to continue to promote awareness of this disease process.

Please feel free to use any of the referenced information provided here to engage in these discussions in visible forums, as we work together towards ensuring our families, friends, communities, and medical professionals of this disease process and the desperate need for further research.

The study:

The UK study, conducted by Groom, H., et al (Retrovirology, 2010) aimed at looking for evidence of XMRV in two UK cohorts, and comparing them to controls. There were 170 samples collected from individuals with chronic fatigue syndrome, and 395 control samples from individuals without the disease. The research looked for evidence of XMRV in these samples by either identifying the presence of viral nucleic acids of XMRV, using PCR techniques, or by identifying serological responses in the samples, using a virus neutralisation assay (Groom, H., et al 2010).

First of all, the research looked for evidence of the viruses genetic code in the samples using PCR (Polymerase Chain Reaction). PCR is a method of amplifying a sequence of DNA and then looking for the specific genetic code of XMRV. (There's an simplified example of PCR at http://learn.genetics.utah.edu/content/labs/pcr/ which demonstrates this process in terms that even I can understand!) The research then looked for serological responses in the samples, evidence of XMRV antibodies, which would indicate that the immune system had been activated by XMRV, and had rallied up specific antibodies to fight the virus.

The results:

The results of the study undertaken by Groom, H., et al (2010) failed to identify XMRV by PCR methods in any of the samples.

26/565 samples tested positive for serological activity in response to XMRV, however, according to Groom, H., et al (2010), 25 of these samples were from individuals in the control group. This means only one individual who had a diagnosis of CFS demonstrated neutralising activity towards the virus XMRV. In other words, that sample had antibodies which could target XMRV.

I say 'could' because most of the 26 samples which tested positive for these antibodies, also demonstrated the ability to nutralise the virus particle if it was wrapped in an alternative viral protien coat. So, remembering that a virus is a length of viral DNA wrapped in a protien coat, when the researchers changed that usual protien coat on the virus to a protien coat from a different virus, the samples continued to show a neutralising serelogical response. This may indicate that another virus could have elicited these responses, and thus the antibodies residing in these samples were not necessarily responding to the XMRV.

There was detection of a serological response in 4 samples that was not elicited by a psuedotyped virus, meaning there were 4 samples which elicited a serological response to XMRV only


The conclusions drawn by this research was that there may be a danger in getting accrate results from serological surveys, because the antiviral response to XMRV may also be elicited by other viruses.

One reason why this was deflating for many individuals hoping to see positive results, is because of the involvement of Dr Jonathan Kerr. One of the researchers involved in this research paper, is Dr Jonathan R Kerr BSc, MBBCh, MD, PhD, FRCPath. Dr Jonothan Kerr received his medical qualification from Queens University of Balfast in 1987, and in 1995, he completed his qualifications at a microbiologist, has worked as a microbiologist in Balfast, Mnachester, and London, where, in 2001, he became the consultant senior lecturer in Microbiology at the Imperial College, and in 2005 became the Clinical Senior Lecturer in Inflammation at St Gorges University (IACFS/ME, 2010). Dr Jonathan Kerr worked on a study of parvovirus B19 infection, demonstrating a percentage of cases had developed 'CFS' which lasted for several years, and subsequently became interested in 'Chronic Fatigue Syndrome' (IACFS/ME 2020). IACFS/ME (2010) reports that "he is now the principal investigator in a programme of research on CFS", and is is interested in the genetics of "CFS", and potential relationship with microbial infections.

A discussion of the study:

Of the study, Kate Bishop, one of the researchers, stated "We are confident that, although we were unable to replicate the detection, our PCR assay is more sensitive than the earlier method and possessed the necessary sensitivity to detect XMRV had it been present" (Redorbit, 2010). However, this study fails to provide detail to allow interpretation of how many white blood cells were analyzed, and as a result, this may have impacted the results. The Whittemore Peterson Institue, (2010), have stated that "Insufficient number of cells analyzed may result in failure to detect a low copy virus like XMRV, regardless of the sensitivity of the assay'

The Whittemore Peterson Institute (2010) also stated a difference in collection, preparation and storage of DNA. Neither this UK study, or that published in PLoS, had any data on blood harvesting, storage, or quantity of isolated cells, and technologies used. The research paper published in Science had used "PCR on nucleic acids from both un-stimulated and stimulated white blood cells; XMRV protein expression from stimulated white blood cells; they completed virus isolation on the LNCaP cell line; and a specific antibody response to XMRV" (Whittemore Peterson Institute, 2010). Furthermore, the Whittemore Peterson Institue, (2010), 'When using PCR alone, the Science authors found that four samples needed to be taken at different times from the same patient in order for XMRV to be detected by PCR in freshly isolated white blood cells. More importantly, detection methods other than PCR showed that patients whose blood lacks sufficient amount of XMRV detectable by PCR are actually infected'.

In conclusion, this study is not a replication study. Realistically, a replication study requires the same environmental conditions and technologies are used. The Whittemore Peterson Institue, (2010) have stated that they have provided information and reagents to research groups in different areas to assist accurate replication studies to occur, however, neither this study, or the one published bu PLoS, 'requested positive control blood, plasma or nucleic acids'. This demonstrates that there is still a need for direct replication studies to take place before any concrete statements about the corrolation between ME/CFS and XMRV (causative or coexistant) can be made.

Post exertional malaise

This is a revised blog entry.  There was some ambiguity identified in the previous post, which I have aimed to address.  Thank-you to each of those people who assisted with this, who have chosen not to identify themselves.  I am most grateful for your support and assistance.

Post exertional malaise is a familiar to many individuals with ME/CFS, and for those who have had this disease for several years or longer, it is likely to be a facet of the disease which is very disabling.  Some of us have learned to live within the confines of this symptom of ME/CFS, however it does pose many unseen limitations to how an individual may participate in their activities of daily living (housework, for example) personal activities of daily living (personal care).

Malaise is the term used by the Canadian Consensus Document to describe the onset of exacerbated signs and symptoms of ME/CFS, including cognitive function deterioration, and increased pain and fatigue. The term malaise is described in most literature as a vague feeling of general unwellness.   Encyclopedia.com states that malaise is a 'medical term for a general condition of unease, discomfort, or weakness' (Retrieved 10 February 2010), and the Oxford Nurses Dictionary, (4th ed.), defines malaise as 'the general feeling of being unwell. The feeling may be accompanied by a feeling of physical discomfort, and may indicate the presence of disease' (McFerran, 1998).

Individuals with ME/CFS identify this 'malaise' as the onset of exacerbated signs and symptoms of the disease, following a period of physical or mental exertion. For individuals with ME/CFS, it is common for this feeling to follow active physical exertion, such as going for a walk, hanging out the washing, cooking a meal, etc. Post exertional malaise typically lasts 24 hours or more following an activity or exercise.

For the purposes of this post, I will be using the word activity, and delineating it from the word exercise.  I will use the word 'activity' to describe the engagement of the body or the mind in tasks associated with daily living, as opposed to 'exercise'; the engagement of physical training to develop fitness and improve health.  I will not be addressing exercise or aerobic training.

There are physical signs associated with the symptom of post exertional malaise, which can be demonstrated by comparing an individual with ME/CFS with a healthy individual after participating in physical activity. An individual without ME/CFS will often experience anti depressant effect as a result of physical activity. This is caused by the increase of oxygen-carrying blood to the whereas individuals with ME/CFS show a decrease in oxygen and blood to the brain, which contributes to the feeling of malaise (van de Sande, 2009).  Individuals with ME/CFS demonstrate hypo-profusion of blood through particular areas of the brain, which means a decreased blood flow through the brain tissue, which is further decreased as a result of physical activity (van de Sande, 2009). This is the opposite of the effect of physical activity on the brain tissue of an individual who does not have ME/CFS (van de Sande, 2009). Body temperature normally increases with physical activity, however individuals with ME/CFS demonstrate a decreased body temperature after exercise (van de Sande, 2009).  A table of this can be found on page four of the Canadian Consensus document.

A further effect of the decrease of blood circulation in the brain is the decrease of the effect of endorphins on how an individual feels after exercise.  Endorphins are the body’s natural analgesics, (pain killers), which contribute to a increased sense of wellbeing in individuals without ME/CFS, after participating in physical exertion.

Although on average individuals with ME/CFS have an elevated resting heart rate, they typically demonstrate a significantly reduced heart rate when they are participating in an activity at their maximum workload. Individuals with ME/CFS also demonstrate 'an inability to reach the age-predicted target heart rates (van de Sande, 2009). Van de Sande, (2009), refers to a study completed by De Becker, et al (2000) which demonstrated that the maximum oxygen uptake and maximum workload attained by individuals with ME/CFS was approximately half that of sedentary controls. This could be attributed to autonomic dysfunction and/or heart dysfunction, which means that it is advisable for individuals who have ME/CFS not to try to attain age-predicted heart rates(van de Sande, 2009).  Other dysfunctions which are common for individuals with ME/CFS to experience after physical activity include impaired cognitive function, orthostatic intolerance and gait disturbance (van de Sande, 2009).

A dysfunction found in individuals with ME/CFS is Mitochondrial Myopathy.  The National Institute of Neurological Disease and Stroke define mitochondrial myopathy as a neuromuscular disease ‘caused by damage to the mitochondria—small, energy-producing structures that serve as the cells' "power plants” (May 2007).  Dr Cheney stated that in ME/CFS there is so much injury to the mitochondria that CFS could be called a mitochondrial disease (Seiverling, 2001).  This does not mean that the individual does not have ME/CFS, but that mitochondrial dysfunction plays a role in the disease pathology.  There is a link at the bottom of this blog entry which contains further information on mitochondrial myopathy, as discuss by Dr Cheney.

The following discussion on management techniques, which in some areas are used as part of generalized Cognitive Behaviour Therapeutic approaches.  This blog aims to discuss these techniques in isolation from any CBT intervention, as techniques which need to be carried out with care and support from a well educated medical team.  Again, the management techniques of pacing and grading will be discussed with regard to ADL’s and PADL’s, and not with reference to aerobic exercise programs.  Please use this for information and education purposes only, and do not embark on any physical exertion program without medical advice and support.

For individuals with ME/CFS, the subject of physical exertion can be a very sensitive and difficult one to address.  This is due to the nature of ME/CFS, where the disease is an exertional one (Lapp, 2006). There are small management techniques which individuals with ME/CFS may implement with support from a medical team, that can be used to help achieve activities.  Needless to say, this requires much forethought and planning. 

One of these managing techniques is grading.  Grading is the SLOW building up of tolerance to a realistic activity which has a predefined end point from the outset.  This end point is different for each individual.  The endpoint at which grading an activity stops, is the point at which participating in an activity can occur without ill effect, or post exertional malaise.  For example, an individual with ME/CFS might begin vacuuming for one minute every two days and build up to five or six minutes every two days before having a rest period. 
It is important to note that this is not a treatment technique, and does not lead to remission of ME/CFS signs and symptoms. Over four weeks, Black, et al (2005) found that  individuals with ME/CFS were able to increase their activity level, however, studies fatigue, muscle pain, and overall mood did not improve with increased activity. Black, et al., (2005) established from this that there is a limit to activity/exertion tolerance.  This means that an individual with ME/CFS may build up from a period of one minute to a period of six minutes of vacuuming over four weeks.  At six minutes on a good day, the activity is managed whilst still feeling a sense of wellbeing and absence of complete relapse, however this may remain the threshold, and any subsequent activity without a substantial rest period would tip the balance.

A good measure for a starting point of activity participation, is the amount of activity an individual with ME/CFS is able to tolerate on a bad day.  For some individuals, the extent of this may be getting out of bed and going to the bathroom and returning to bed for a rest.

Pacing of activity is another management strategies, where an activity, say hanging out the washing, is broken up into manageable chunks. An example may be hanging out three towels (the heaviest items) and having a break (for some people five minutes, for some people thirty minutes). The next would be hanging up two or three pairs of jeans, break, sweaters, break, then the socks, break, and underwear (lightest of the washing), so that as the activity proceeds, less and less exertion is required as the fatigue and ‘malaise’ sets in.

In the absence of being able to participate in an activity, i.e., for individuals who are bed bound, some techniques which may be beneficial include active and passive stretching of joints through range of motion.  Active stretching is the participation in a stretching activity independently; passive stretching requires that the individual is relaxed while someone moves each joint through a range of motion.  Even rolling over in bed is a form of stretching. 

In summary, individuals with ME/CFS should not view activity or exercise as a means by which they will recover.  Exercise done without support from properly educated medical professionals can be dangerous.  Instead, physical movement should be seen as an opportunity to avoid muscle atrophy and further weakness.  This means, once again, individuals with ME/CFS are in a position where they may need to take on a role of education within their medical teams.  I have included some resources below to assist with this.
