Differences in ME & CFS symptomology in patients with normal and abnormal exercise test results

Differences in ME and CFS symptomology in patients with normal and abnormal exercise test results, by Stephanie L McManimen and Leonard A Jason in International Journal of Neurology and Neurotherapy 2017, vol 4 issue 1, 4:066 [Published: March 21, 2017]

Research abstract:

Post-exertional malaise (PEM) is a cardinal symptom of myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS), which often distinguishes patients with this illness from healthy controls or individuals with exclusionary illnesses such as depression. However, occurrence rates for PEM fluctuate from subject to how the symptom is operationalized. One commonly utilized method is exercise testing, maximal or submaximal. Many patients with ME and CFS experience PEM after participating in these tests, and often show abnormal results.

However, some patients still exhibit normal results after participating in the exercise testing. This study examined the differences between two patient groups with ME and CFS, those with normal results and those with abnormal results, on several PEM-related symptoms and illness characteristics. The results suggest those that displayed abnormal results following testing have more frequent and severe PEM, worse overall functioning, and are more likely to be bedbound than those that displayed normal results.

Excerpt from research article:

These findings suggest there is a subgroup of patients with ME and CFS that is more functionally impaired than the rest of the patient population. Although both groups of
participants endorsed PEM-related symptoms, the group with the abnormal results displayed higher frequency and severity for the symptoms. Since this group appears to
be more impaired, they may have a lower threshold for exertion, which could result in them experiencing PEM more quickly than the group with normal test results.

Conversely, the group with normal test results may require more exertion before the results would differ from those of healthy controls as they are not as functionally impaired
as the group with abnormal test results.

This finding result in a heterogeneous patient population for research involving exercise testing, which may help explain the discrepant results found in previous studies.

Additionally, since the group with abnormal exercise test results is more likely to be bedbound or housebound, it is possible that they are unable to make it to a tertiary
clinic to participate in these research studies. As a result, the more severely impaired group patients with ME and CFS may be excluded from analyses comparing the full patient population to healthy control populations. This could prevent researchers from finding significant differences between patients and controls if the more impaired patients
are unable to participate in research.

This study has several limitations. First, this study used an international convenience sample. All participants had a self-reported, current diagnosis of ME or CFS so there was no standardized diagnostic criteria necessary to participate in this study. The study also included participants from many settings and countries. Previous research has shown differences in patient populations between US and UK samples.

However, this may actually be seen as an advantage as it would allow for us to generalize the results across various settings (i.e. tertiary care, community, and primary care samples) and geographic locations.

Additionally, we do not have information on the types of tests that were performed, submaximal or maximal. The participants self-reported that they had previously
received normal or abnormal exercise test results. Future research should examine the functional and symptomatic differences between the patients with normal and abnormal
results in a controlled, standardized study to form a more homogenous patient sample.

WAMES supports proposal to continue classifying ME as neurological

WAMES supports proposal to classify ME as neurological

WAMES has submitted our comment on a proposal for the revision of the World Health Organisation’s International Classification of Diseases (ICD):

The Welsh Association of ME & CFS Support (WAMES) supports the proposal for the ICD-11 revision submitted by Chapman and Dimmock on 27th March 2017.

WAMES agrees that Myalgic encephalomyelitis (ME) and Postviral fatigue syndrome should continue to be classified at G93.3 in the chapter on Diseases of the nervous system.  Although research has found dysfunction in a number of the body’s systems (e.g. neurological, immune, endocrine, autonomic) there is significant Central Nervous System involvement and unless research provides a clearer and different picture of the aetiology of the condition, it should not be moved. In addition, the symptoms often present in a similar way to other neurological conditions (e.g. MS) so it fits naturally in this category.

We agree that the term “Chronic Fatigue Syndrome” and “Myalgic encephalomyelitis” should be the concept titles, with separate codes, as the terms are not always used to mean the same thing and are likely to be increasingly identified with different subgroups of illness.  We agree that “Postviral fatigue syndrome” should be removed as a lead term because not all cases are postviral. We also agree that the ICD-10 term “benign myalgic encephalomyelitis” should be modified to “myalgic encephalomyelitis” as the condition is not benign. It is complex and leads to considerable debility.

WAMES believes it is important that ICD-11 should not contribute to the current confusion amongst many health professionals between, on the one hand Myalgic encephalomyelitis (ME) and Chronic Fatigue Syndrome (CFS), and on the other hand idiopathic chronic fatigue, bodily distress disorder (BDD) / medically unexplained symptoms (MUS) etc. Exclusions for ME and CFS should be noted in the revised section on somatoform disorders in the Mental health section of ICD-11.

  • 549 individuals or organisations have agreed with the proposal
  • over 380 comments have been submitted
  • 53 organisations from around the world have responded

ME Awareness – Missing years

Missing years – ME/CFS Awareness

These squares have been lovingly crafted in a bid to raise awareness of the little understood but devastating diseases known as ME (Myalgic), Chronic Fatigue Syndrome and Fibromyalgia. They show the number of years that sufferers have lost to these illnesses and will be featured on the Missing years Facebook page throughout May.

Many contributors are too unwell to leave their homes (and sometimes their beds) very often, too ill to work or take part… in sporting or social activities. They range in age between 17 and 69 years old and live mostly in the UK, the USA and Australia.

The total number of years lost to illness by the 55 people who participated, depicted in the squares, is 1109. On average that is 20 years and 2 months per person.

This is even more shocking when you consider that some people have only included the more severely affected years when life as they once knew it changed completely, ignoring those times when they were experiencing symptoms but still able to push on regardless. The squares depict lengths of illness ranging from 4 to 45 years, though one participant has been ill for all of her 69 years: she couldn’t bear to put such a high number.

Making the Squares

A few of the techniques used to make the squares include: paper cutting, digital portraiture, marbling, collage, ink and wax, coloured pencils, chalk, pre-loved birthday cards, buttons, flowers, photography, knitting, crochet, sewing, cross stitch, origami and a pretend concrete block.

Some people required help from more able participants to make their square. Out of the hundred people who intended to make a square, only about 40 managed to complete one even with the offer of help. Several people noted how difficult it was to complete the square physically even over a period of months, and many found it emotionally challenging.

We have found it moving looking at other people’s squares, we hope you will too.

How are you planning to mark ME awareness day / week / month this year? Tell us and we will let everybody know.

Regular use of saline may reduce symptoms, boost energy in POTS (& ME/CFS?)

Health rising blog post by Cort Johnson, 15 April 2017: Regular use of saline may reduce symptoms, boost energy in POTS (& ME/CFS?)

ME/CFS and POTS patients have used saline for years to feel better and recover from relapses. That’s really no surprise. The documented low blood volume in both groups suggests that saline would be an excellent temporary help. One chronic fatigue syndrome (ME/CFS) patient suffered a relapse after surgery that lasted and lasted until she got on saline, after which she recovered quickly. That, in retrospect, was no surprise, either. Anesthesia can be dehydrating and most of us are, as Dr. Klimas says, a quart or so low in blood volume.

Saline is no panacea: it often helps but does not cure ME/CFS or POTS and its effects don’t last long. Still, it’s a kind of secret weapon that many ME/CFS practitioners use to give their patients temporary relief.

That appears to be unusual for a disease. Check out a web page on saline and you probably won’t see any diseases mentioned.  (Search “saline IV” on Bing, however, and the first disease that pops up is Chronic Fatigue Syndrome.)  Saline IV’s are generally used in medicine when patients can’t take water by mouth or when they’re dehydrated or to transmit medicines,.  Almost always used in “acute” situations where blood volume has dropped precipitously due to blood loss or other reasons, saline IV’s are rarely used chronically.  In fact, the authors of the study below stated that medical authorities do not recommend other than temporary use of saline

Although saline has been used in ME/CFS/POTS for decades by ME/CFS experts. research has been minimal.   A 1997 study found that giving 1200 mg sodium chloride daily for three weeks enabled half of the ME/CFS patients with low blood pressure upon standing (orthostatic hypotension) who had failed a tilt table test to pass it.  (Those who did not improve had problems with low renin levels). Similarly, Burklow, in a 1999 study, found that giving adolescents saline allowed all of them to pass a 30 minute tilt table test without fainting.

More recently, a 2014 study found that a single saline infusion did not significantly improve POTS patients’ ability to exercise a couple of hours later. (The authors speculated that POTS patients might feel better but still not be able to exercise, and that repeated infusions might be needed to help with exercise.)

Now comes a 2017 saline study in POTS which suggests that regular saline use might be very helpful indeed.

The Study

Effects of intermittent intravenous saline infusions in patients with medication — refractory postural tachycardia syndrome. Mohammed Ruzieh1,2 & Aaron Baugh1 & Osama Dasa1 & Rachel L. Parker1 & Joseph T. Perrault1 & Anas Renno1 & Beverly L. Karabin1 & Blair Grubb1. J Interv Card Electrophysiol (2017) 48:255–260 DOI 10.1007/s10840-017-0225-y

In this study the average patient received between 1.1 and 2.1 L of saline every 10 days or so for three to six months. The Orthostatic Hypotension Questionnaire (OHQ) which evaluates symptoms and functionality, and the short-form SF-36 which evaluates quality of life were used to assess the effects of the saline. No control group was used.

Mostly younger females with idiopathic POTS participated, but a significant number (25%) also had Ehlers Danlos Syndrome (EDS).   They were followed for 3-12 months and were allowed to have infusions when requested.

Results

In conclusion, intermittent IV infusions of saline dramatically reduce symptoms in patients suffering from postural tachycardia syndrome. Paired with its relative safety and low cost, this makes it an ideal candidate for bridge therapy to allow the implementation of long-term interventions in highly symptomatic patients.  The authors

 The results were impressive. Over 90% of the participants experienced significant improvement in symptoms lasting an average of three days. The average OHO score dropped in half (from 6.6 to 3.1). Dizziness symptom scores dropped from 7.2 to 2.8, fatigue scores from 8.2 to 4.3, weakness from 6.3 to 3.4.  The patients’ ability to stand for a long time and walk for a short or long time about doubled.

The consistentcy of the response was remarkable given the high failure rate of other medications in this condition. Almost 70% had tried and failed to improve on beta blockers. Fifty percent had failed with midodrine, 44% with SSRI’s and SNRI’s, 42% with desmopressin and 30% with fludrocortisone.  Each patient had tried and failed to improve on almost four drugs.

At some point 50 of the participants reported no need for further infusions, except during times of stress, within six months of starting the infusions.

A Bridge Therapy?
So how did the authors believe that IV infusions every ten days or so which provided symptom relief for about three days translate into long-term relief? They didn’t know, but their best idea was that IV infusions gave the POTS patients a window to increase their activity levels and relieve the effects of deconditioning that often come with the disease. Ultimately, many didn’t feel the need to have more IV infusions at all.

The authors noted that deconditioning is common in POTS and poses significant problems. Plus, reduced stroke volume – a common finding in POTS – can be improved by exercise.

The exercise situation in POTS, though, is complex. Because many people’s POTS symptoms get worse during exercise or any activity that involves standing, they very naturally stop those activities altogether, which can lead to deconditioning and symptom worsening.

Exercise is commonly used as a therapeutic intervention in POTS.  That’s not to say that exercise is easy to accomplish in this illness or that it works in all POTS patients. POTS patients are told at one clinic that it will take five weeks of exercise before they’ll feel better and that they will feel worse at first. That’s obviously a tough gig. Why exactly it works isn’t clear. (I’ve been told that some researchers believe long-term exercise programs cause epigenetic changes in the immune response.) One study found 71% of POTS patients experienced a remission of their symptoms during exercise therapy, but almost 25% dropped out.

Earlier Health Rising reported the story of a young man with infection induced POTS who found that iron infusions helped him exercise again. (He was unable to tolerate much exercise before the infusions.)  The final step in that young man’s journey to health, though, was a long-term stay at a Mayo clinic that featured, among other things, regular exercise.

Have doctors been missing the boat on saline IV’s and POTS?
The authors of this study believe that the relief experienced after the IV infusions may have allowed the POTS patients to increase their activity levels, which then allowed them to improve further.  (Exercise, interestingly, does increase blood volume). The POTS patients were not well; they still experienced symptom problems from their POTS, but their symptoms scores suggested their orthostatic intolerance, fatigue, weakness and other symptoms were much improved.

This study has some significant limitations. Because no placebo-controlled group was present, placebo effects may have contributed to the patients’ symptom reduction. The study group was also relatively young (average age mid-30’s) and healthy (few other comorbidities).  It’s not clear if ME/CFS/POTS patients were part of the study or not.

Because there was no attempt to assess exercise levels, no objective evidence backs up the authors’ belief that IV infusions increased exercise levels, which then had additional positive effects. Because medication use was not tracked, it’s possible (but not likely) that other medications contributed to their improved health as well.

Saline IV’s Largely Ignored as POTS Treatment
Despite the blood volume depletion and several intriguing study results, saline IV’s – even for temporary relief – aren’t  recommended or even discussed in several POTS journal  and web overviews.

Time to Rethink Saline?
Is it time to consider regular use of saline in POTS and chronic fatigue syndrome (ME/CFS)? Bigger and better studies are clearly needed, but saline IV’s are cheap and safe (when PICT Lines are not needed).  Because blood volume is low in ME/CFS a similar result – a positive feedback loop resulting in increased activity levels over time – might be possible.  If increasing blood volume allows more activity or exercise and if activity/exercise in turn increases blood volume then might some consistent improvement emerge?

There are other ways to increase blood volume. Medow recently scored an NIH grant to assess the effects of oral rehydration solution in ME/CFS/POTS.  The World Health Organization formula for oral rehydration solution is stunningly cheap and easy to make.

ME/CFS linked to imbalanced microbiome

Columbia University Mailman School of Public Health Press release, 26 April 2017: Chronic fatigue syndrome linked to imbalanced microbiome

Scientists identify abnormal levels of specific gut bacteria in individuals with chronic fatigue syndrome, including those with and without co-morbid IBS

Scientists at the Center for Infection and Immunity (CII) at Columbia University’s Mailman School of Public Health have discovered abnormal levels of specific gut bacteria related to chronic fatigue syndrome/myalgic encephalomyelitis, or ME/CFS, in patients with and without concurrent irritable bowel syndrome, or IBS. Findings are published in the journal Microbiome.

The study is among the first to disentangle imbalances in the gut bacteria in individuals with ME/CFS and IBS. ME/CFS is a complex, debilitating disorder characterized by extreme fatigue after exertion and other symptoms including muscle and joint pain, cognitive dysfunction, sleep disturbance, and orthostatic intolerance. Up to 90 percent of ME/CFS patients also have IBS.

The researchers followed 50 patients and 50 matched healthy controls recruited at four ME/CFS clinical sites. They tested for bacterial species in fecal samples, and for immune molecules in blood samples.

They report:

  • Levels of distinct intestinal bacterial species–Faecalibacterium, Roseburia, Dorea, Coprococcus, Clostridium, Ruminococcus, Coprobacillus–were strongly associated with ME/CFS; their combined relative abundance appeared to be predictive of diagnosis
  • Increased abundance of unclassified Alistipes and decreased Faecalibacterium were the top biomarkers of ME/CFS with IBS; while increased unclassified
  • Bacteroides abundance and decreased Bacteroides vulgatus were the top biomarkers of ME/CFS without IBS
  • An analysis of bacterial metabolic pathways associated with disturbances in gut bacteria revealed distinct differences between ME/CFS and ME/CFS subgroups relative to healthy controls
  • In ME/CFS subgroups, symptom severity measures, including pain and fatigue, correlated with the abundance of distinct bacterial types and metabolic pathways
  • No changes were observed in immune markers–a finding that may reflect the dearth of participants who had been ill for a short time; earlier research suggests immune changes may only be evident when comparing short and long duration cases

“Individuals with ME/CFS have a distinct mix of gut bacteria and related metabolic disturbances that may influence the severity of their disease,” says co-lead investigator Dorottya Nagy-Szakal, postdoctoral research scientist at CII.

“Our analysis suggests that we may be able to subtype patients with ME/CFS by analyzing their fecal microbiome,” says co-lead investigator Brent L. Williams, assistant professor of Pathology and Cell Biology at CII. “Subtyping may provide clues to understanding differences in manifestations of disease.”

“Much like IBS, ME/CFS may involve a breakdown in the bidirectional communication between the brain and the gut mediated by bacteria, their metabolites, and the molecules they influence,” says senior author W. Ian Lipkin, director of CII and John Snow Professor of Epidemiology at Columbia’s Mailman School. “By identifying the specific bacteria involved, we are one step closer to more accurate diagnosis and targeted therapies.”

The Stanford Paradox: elevated energy production found in ME/CFS

Health rising blog post, by Cort Johnson, 18 April 2017: The Stanford Paradox: Elevated Energy Production Found in Chronic Fatigue Syndrome (ME/CFS)  

Producing energy is a big problem in Chronic Fatigue Syndrome (ME/CFS). In fact it’s probably the problem in ME/CFS, which is why the findings of mitochondrial dysfunction and lowered ATP production have made sense. When the metabolomics studies suggested that chronic fatigue syndrome (ME/CFS) was a hypometabolic state, the field seemed set: energy production (ATP) was low and the mitochondrial activity probably was too. Fatiguing disease and low ATP production: it seemed to make so much sense.

Then came the study with the eye-catching title: “Elevated Energy Production in Chronic Fatigue Syndrome Patients.” It suggested that far from being low, cellular energy production was actually abnormally high in ME/CFS patients. Even for a field that’s had more than its share of inconsistent findings, that was a real lu-lu.

The results, though, could not be ignored. They didn’t come from a small research group but from the Xinnan Wang Lab at Stanford.  Last year the lab – which is devoted entirely to studying the mitochondria – made headlines with its potentially seminal finding in Parkinson’s disease.  It uncovered a defect that prevented Parkinson’s patients from removing their mitochondria as their mitochondria start to wear out. That defect left those mitochondria pumping toxins into the brain.  Because the defect was present in different types of Parkinson’s patients, it suggested that a “mitochondriopathy” might lie at the core of the disease.

Plus the patient samples in the Wang ME/CFS study came from some of our best ME/CFS experts. Plus it was funded by an ME/CFS group – the Chronic Fatigue Initiative – that hires only the best researchers. There was no looking past this result.

A content analysis of CFS & ME in the US news from 1987 to 2013

Research abstract:

A content analysis of chronic fatigue syndrome and myalgic encephalomyelitis in the news from 1987 to 2013, by Zachary A Siegel, Abigail Brown, Andrew Devendorf,  Johanna Collier, Leonard Jason in Chronic Illness [Preprint April 2017]

Objectives:
The aim of this study was to analyze the content of American newspaper articles (n=214) from 1987 to 2013, in order to understand how the public digests information related to Chronic Fatigue syndrome, a controversial and misunderstood illness.

Methods:
A novel codebook derived from the scientific literature was applied to 214 newspaper articles collected from Lexis Nexis Academic(r). These articles were coded quantitatively and frequency tables were created to delineate the variables as they appeared in the articles.

Results:
The etiology was portrayed as organic in 64.5% (n=138) of the articles, and there was no mention of case definitions or diagnostic criteria in 56.1% (n=120) of the articles. The most common comorbidity was depression, appearing in 22.9% (n=49) of the articles. In 55.6% (n=119) of the articles, there was no mention of prevalence rates. In 50.9% (n=109) of the articles, there was no mention of any form of treatment for the illness. A total of 19.4% (n=42) of the headlines mislabeled the name of the illness.

Discussion:
Based on descriptive statistics of all 214 coded articles, media communicated mixed messages for salient variables such as the name of the illness, its etiology and treatment.

CFS and the immune system

Review summary:

Chronic fatigue syndrome and the immune system: Where are we now?, by Fane Kojo Fosu Mensaha, Amolak Singh Bansal, Brian Ford, Geraldine Cambridge in Neurophysiologie Clinique/Clinical Neurophysiology [Available online 12 April 2017]

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterised by multiple symptoms including fatigue, headaches and cognitive impairment, which have a significantly adverse effect on the normal functioning and well-being of the individual. These symptoms are often triggered or worsened following physical or mental exertion.

ME/CFS has long been thought of as having a significant immunological component, but reports describing changes in immune function are often inconsistent between study groups. Although the wide range of physical, neurocognitive and autonomic symptoms reported have seriously hampered attempts to understand pathophysiological pathways, investment in biomedical research in ME/CFS is finally increasing with a number of novel and promising investigations being published.

The onset of ME/CFS may often be linked to (viral) infections which would be consistent with a variety of alterations in natural killer (NK) cell function as described by a number of different groups.

Consistency in cytokine data has been lacking so far, although recently more sophisticated approaches have led to more robust data from large patient cohorts. New hope has also been given to sufferers with the possibility that therapies that deplete B cells can result in clinical improvement.

To understand the pathogenic mechanism in this complex condition, it is important to consider repeated analysis in different cohorts. In this review, we will discuss the potential of different components of the immune system to be involved in the pathogenesis of ME/CFS.
