The 2nd International Symposium For CFS/ME Overview By Rosamund Vallings

Reprinted with kind permission of Health Rising.

(Note: The text is by Dr. Rosamund Vallings of New Zealand.  Commentary (in brackets) is from Cort Johnson.)  

December 2013, Gold Coast, Australia. I felt privileged to be invited to attend this symposium, which was combined with the opening of the National Centre for Neuroimmunology and Emerging Diseases (NCNED) at Griffith University. The campus at Griffith is new and adjacent to the new 750-bed Gold Coast Hospital.

The programme for the day began at Griffith University with the Opening Ceremony for the National Centre for Neuroimmunology and Emerging Diseases (NCNED). We were welcomed by Professor Sonya Marshall-Gradisnik, Co-director. She then introduced Professor Allan Cripps, Pro Vice Chancellor Health, Griffith University, who welcomed us, and he then introduced Dr. Elizabeth Unger (USA), who gave a brief opening address before they both unveiled the plaque.

Hugh Perry (Southampton, UK) - Alison Hunter Memorial Foundation address

Hugh Perry (Southampton, UK) gave the inaugural Alison Hunter Memorial Foundation address. However he began his address pointing out that neuro-immunology has a large role to play in the understanding and research associated with ME/CFS. He reiterated how much Christine Hunter (AMHF) had raised so much the awareness of the illness.

The first part of his talk explained the Medical Research Council (MRC) mission. The MRC has been established for 100 years. The mission is to encourage research, produce skilled researchers, disseminate knowledge and bring dialogue to the table. ME/CFS research has been supported since 2003. A strategy document was produced in 2008 – leading to an expert group incorporating external researchers for collaboration. The idea was to bring in new people, new research and new technologies.

One of the big challenges was the unmet clinical need (up to 600,000 sufferers in the UK). Grants were initially low as there was no clear pathology and no targeted therapies. Treatment has been geared towards support and symptom control. There is need to define phenotypes and sub-phenotypes and embrace new technology.

He then outlined a prioritization of topics for research: Autonomic dysfunction, cognitive symptoms, fatigue, immune dysregulation, pain and sleep. There is a need to bring in external expertise. In the medium term there is need to encompass comorbidity and chronicity, susceptibility and resilience, mitochondrial function, use of well characterized cohorts and development of intervention (e.g., cytokine inhibition). In the long term there should be development of imaging technologies, assessment of genetic risk and review of neurobiological changes (e.g., cerebral activity).

The MRC is currently funding new research looking into the mechanism of ME/CFS (1.6 million pounds). There needs to be partnership with new researchers to qualify for grants, and a focus on one of the 6 topics listed above.

So far the following awards have been made:

  • Mitochondrial function

  • Autonomic dysfunction

  • Biological fingerprints of fatigue

  • Slow-wave sleep and daytime function persistent fatigue induced by interferon? (a new model for ME/CFS)

This brings together funders and ME Charities. The MRC acts as an observer. The aim is to collaborate the ME charities and to increase awareness with the research community. The key to success is that research should drive the agenda, the “bottom-up” approach and the engagement of researchers outside the field. This has led to the First UK CMRC Research conference to be held in Bristol in September 2014.

[The MRC's research docket is not large, but it contains some fascinating studies. Below are overviews of a few of them.  

The McCardle Mitochondria Study

"This ... will lead to a definitive answer regarding a mitochondrial defect in muscles of patients with CFS." McCardle

McCardle asserts her study will answer the mitochondria question in ME/CFS… McCardle’s mitochondrial and cytokine skeletal muscle study is using techniques developed in her lab to test the hypothesis that mitochondrial abnormalities produce free radicals that initiate a state of low-level inflammation in ME/CFS.  Free radical activation of the inflammatory mediator NF-kB produces pro-inflammatory cytokines that further dysregulate the mitochondria resulting in a vicious circle of more free radicals, more cytokines, etc. McCardle is very confident of her new approach, stating it will provide a ‘definitive answer’ (!) to the mitochondrial question that’s been dogging researchers for years in ME/CFS.

Dr. Julia Newton and the Autonomic Nervous System  

“This programme will lay a foundation … that will enable a future set of diagnostic tools, system based explanations of dysfunction, a new generation of therapies and ultimately clinical protocols that will counter the biological processes that underpin fatigue in a range of diseases.” Dr. Newton

Dr. Newton’s study is equally exciting. Stating that it will also use ‘novel technologies’,  Newton’s study will attempt to determine whether the autonomic nervous system issues in ME/CFS are driven by problems in the brain or the periphery.

[Newton’s most recently published study suggested that pH handling problems in the muscle could be causing the reduced cerebral blood flow.]

The first part of the study will use “ground breaking dynamic magnetic resonance (MR) modalities” to examine brain functioning. The second part will determine how much cardiovascular dysfunction in the periphery contributes to the blood flow problems in the brain.

Using the Fatigue in Sjogren’s Syndrome to Understand the Immune Problems in ME/CFS – Ng

“By uncovering the abnormalities of the immune system in CFS in detail, it will help make the diagnosis of CFS easier and more accurate as well as give us clues to develop effective treatment of this condition.” Ng

Ng believes the fatigue in disease is primarily immune mediated and is driven by the same immune processes in different disorders. Since the definition of chronic fatigue syndrome is so nebulous and the patients so heterogeneous, he chose to use Sjogren’s Syndrome to get at the heart of immune mediated fatigue in chronic illness. Ng will use gene expression and markers of immune dysregulation from a group of 550 Sjogren’s Syndrome patients to produce a biological profile of immune induced fatigue. He will then look for that ‘biological signature’ or biomarker in people with ME/CFS.]

Perry Part II: Impact of Systemic Inflammation on the Brain

The second part of the address focused on the Impact of Systemic Inflammation on the Brain. He described how diseases “talk” to the brain, and how infection makes you feel “sick”. Inflammation changes behavior. These symptoms can be the same as those experienced by those with ME/CFS.

This highly organized strategy is critical to survival if living in the wild. Systemic inflammation activates selective brain regions. Infection causes a localized inflammatory response, with release of pro-inflammatory cytokines, which then communicate with the brain.

The cytokines act on the endothelial cells, which in turn affect the macrophages in the brain (microglia) – and microglia play a key role in immune/brain communication. This is tightly regulated by the brain/micro-environment.

The microglia may become dysregulated, escaping from CNS control, and this leads to massive pathology and symptoms equivalent to microglial activation. The activated microglia may proliferate, leading to neuro-degeneration. The microglia may be primed by decline (e.g., Alzheimer’s disease).

Macrophages are primed by exposure to Interferon and then triggered by infection, which is the secondary stimulus. In a younger population the microglia can be primed by the environment – living in dirty conditions (animal model) predisposes the brain to give a more robust response to infection, which can lead to microglial activation for months.

Smoking and obesity lead to higher levels of cytokines and this in turn leads to more activation of the microglia as if a peripheral disease exists. Lifestyle, systemic infection and genetics all prime the microglia.

The final conclusion/hypothesis was that systemic infection and inflammation, that normally leads to sickness behavior in an individual with a healthy brain, is a homeostatic mechanism with no long term consequences, is distorted and maladaptive in an individual with primed microglia. The question is to find “inhibitors” to penetrate the brain and downregulate the microglia.

[CJ -The Japanese have presented two findings in conferences indicating microglial activation occurs in the thalamus of chronic fatigue syndrome patients. Perched on top of the brainstem deep inside the brain, the thalamus is the switchboard for sensory signals entering the brain. Every sensory signal (except for smell) is routed through the thalamus to different parts of the brain. A major regulator of sleep, awareness, arousal and wakefulness as well, the thalamus could certainly play a major role in ME/CFS.  The Japanese findings suggest  inflammation in present in the thalamus of people with ME/CFS.]

Elena Gonzalez-Rey (Granada, Spain) – Cortistatin – A Possible Future Therapy for Chronic Fatigue Syndrome

Elena Gonzalez-Rey (Granada, Spain) was the next presenter who addressed the issue of therapeutic and physiological relevance of cortistatin as a key molecule in the development and progression of inflammatory and autoimmune diseases. Cortistatin is a cyclic-neuropeptide produced by the brain cortex and immune cells, with unique function, that shows potent anti-inflammatory activity.

She reiterated that homeostasis leads to survival, and that immune homeostasis is protective. The immune system “talks” to the neuroendocrine system via cytokines and neuropeptides. The therapeutic effect of cortistatin gives a good response. She had looked at mouse models and found a good response in MS (EAE).

Cortistatin improves symptoms, reduces inflammatory response, inhibits demyelination, inhibits Th1/Th17 responses and induces regulatory T cells. It also induces the production of trophic factors, modulates the immune response of resident cells and protects against oxidative stress. Severe disease leads to decrease in cortistatin levels. Low cortistatin leads to anxiety and fear behaviours, affects neurogenic processes and induces cognitive problems. (article published in Arthritis and Rheumatism May 2013). This is a potential treatment for ME/CFS.

[CJ –Cortistatin is a relatively new discovery, and the first research papers on cortistatin date back only to 1999.  Cortistatin is receiving a lot of interest, but animal studies dominate at this point and I was unable to find any cortistatin drugs trials listed in the clinicaltrials.gov database.  Cortistatin is one of several neuropeptides being investigated as anti-inflammatories. These include substances such as vasoactive intestinal peptide, pituitary adenylate cyclase-activating polypeptide, alpha-melanocyte-stimulating hormone, urocortin, adrenomedullin, somatostatin, cortistatin, ghrelin, galanin and opioid peptides.]

Mario Delgado (Granada,Spain) – Vasoactive Intestinal Peptide – A Potential Therapy for ME/CFS?

The therapeutic potential of Vasoactive Intestinal Peptide (in auto-immunology) was discussed by Mario Delgado (Granada, Spain). VIP is widely distributed in the body, produced from many organs. It has a plethora of functions. It has been found to be a pleiotropic immunomodulatory factor with potential for use in inflammatory and auto-immune disorders. It is a key factor. Various auto-immune diseases have been studied. It has been found to reduce experimental auto-immune endocarditis in mice, decreases severity of EAE and restores immune tolerance. Questions asked were: Is VIP needed for a healthy immune system, is it ready for clinical use and could it play a role in ME/CFS?

Endogenous VIP and its signalling are critically involved in maintenance of immune tolerance. Clinical use of VIP (Aviptadil) includes treatment of erectile dysfunction, idiopathic pulmonary hypertension and acute systemic respiratory disease. Inhaled Aviptadil is used for alleviation of lung inflammation in sarcoidosis (Treg cells increase). A published article on ciguatera poisoning (Shoemaker May 2010) found that VIP was decreased leading to many symptoms. In another open label study, patients exposed to contaminated buildings had reduced symptoms with inhaled VIP treatment. Inflammation was corrected, Treg cells were normalized and there was enhanced quality of life in all patients. We need to look to see if VIP is decreased in ME/CFS and also whether a VIP infusion could be helpful.

[CJ - VIP is  getting a lot of study everywhere (RA, IBS, epilepsy, high blood pressure, etc.) it seems, but not in ME/CFS. The NCNED did, however, present findings on VIP at a conference this year.  Mast cell activation that triggered VIP (and Substance P) in a recent study of women with IBS  was intriguing given the possibility that mast cells play a role in ME/CFS.  The greatly increased level of the ciguatera epitope found in ME/CFS several years ago indicates a possible tie-in with VIP.]

Gilles Guillemin (Sydney, Australia) – Tryptophan Metabolism

Gilles Guillemin (Sydney, Australia) presented his work looking at the involvement of the tryptophan mechanism in neuro-inflammation. He explained that the kynurenine pathway is a major route of tryptophan catabolism resulting in the production of several neuro-active intermediates. Tryptophan is one of 20 amino acids and is diet sourced. It is a “calming” neurotransmitter and a sleep inducing hormone. The kynurenine pathway is induced during inflammatory brain diseases leading to tryptophan catabolism, and then production of various neuroactive metabolites , including quinolinic acid (QUIN.) This field of research is growing and there is now a Journal of Tryptophan Research. The foetus protects itself against rejection via this pathway.

Human microglia and macrophages produce QUIN, which acutely can lead to neuronal death and chronically to neuronal dysfunction and neurotoxicity. Neuroinflammation can lead to suicidal ideology, (there may be an imbalance with elevated QUIN). QUIN can induce apoptosis in human primary astrocytes. It also induces oligodendrite apoptosis, and affects chemokine production and expression by astrocytes. It is not specific for any particular neurological diseases. The kynurenine pathway is activated and QUIN rises in neuroinflammation. QUIN also rises in various neurological diseases. This pathway is potentially modifiable, and may be a therapeutic option.

Richard Kwiatek (Adelaide, Australia) – Neuroimaging, Chronic Fatigue Syndrome, Depression and Anxiety: Similarities and Differences

Richard Kwiatek (Adelaide, Australia) has looked closely at neuroimaging to differentiate ME/CFS from anxiety and depression. He explained initially how ME/CFS still has not been scientifically validated, and appears to be a multi-system disorder. There has been hot debate over psychological issues. ME/CFS and fibromyalgia models are closely linked to those of regional pain syndrome and a number of psychiatric disorders. Kwiatek found differences between the brains of people with ME/CFS and people with anxiety and depression.

Disturbed immunological, inflammatory, oxidative and stress pathways have overlapping symptoms. Ventricular lactate has been shown to be increased in ME/CFS compared to generalized anxiety disorder. Cortical levels of glutathione compared to ventricular lactate in depression, ME/CFS and controls found that glutathione correlates tightly with ME/CFS. There is a structural peripheral neuropathy in fibromyalgia patients.

He then discussed voxel based imaging, and had studied 25 ME/CFS patients compared to controls. Changes in forebrain white matter were noted in ME/CFS. The analysis was categorical and correlational. When the Bell score was down the disability was greater. When adjustment for depression was included, T1w signals corresponded to severity and T2w did not.

In ME/CFS, myelination in the prefrontal white matter correlated with severity. Kwiatek concluded that ME/CFS may share biological features with anxiety and depression, but present data suggests there appear to be 2 distinct disorders.

[CJ – Expecting there to be a sharp dichotomy between anxiety and depression and ME/CFS is probably unrealistic given the overlap in symptoms and how the body works. Maes has proposed that similar inflammatory factors underlie depression and ME/CFS (and he separates the two as well.). The fact that an ‘antidepressant’ can reduce depression in depressed patients who are not in pain, and pain in chronic pain patients who are not depressed, indicates that similar basic biological processes are in play in these two different disorders.  Indeed, Kwiatek observes that “Disturbed immunological, inflammatory, oxidative and stress pathways have overlapping symptoms.” Given that ME/CFS is, as Kwiatek notes, a multi-system disorder, it can be expected to overlap with many disorders. And, of course, it shares some characteristics with autoimmune disorders and cardiovascular disorders, yet it is distinct from them as well. ]

Sonya Marshall-Gradisnik (Gold Coast,Australia) – NCNED’s Research Direction

Sonya Marshall-Gradisnik (Gold Coast,Australia) opened the afternoon session and explained the current direction of the research at the National Centre for Neuroimmunology and Emerging Diseases (NCNED).

She outlined the research being undertaken by the various members of her team. She explained the importance of looking at the many changes occurring in the immune system and its cells. The NCNED will operate a clinic through which research projects will be undertaken. They will set up a national patient database, which eventually may become international. The search for biomarkers will continue. NK cells are consistantly depleted and cytokine studies are not consistent.

The projects currently undertaken include: looking at: neutrophils, gamma delta T cells, Tregs, cytokines (not consistent over time in ME/CFS), CD+8T and microRNA, gene expression, NK receptor/gene (longitudinal – seem consistent over time),(9 different miRNAs found). They are now looking at CD107 as a marker of NK cell lysis – this may not actually be released by the cell, so what is the mechanism?

Plasmacytoid dendritic cells may contribute to the inflammatory response through the release of cytokines and chemokines, and activation of lymphocytes. Important new directions include: Redoing T cell subsets, looking at B cell subsets (immature B cells and memory B cells) and exploring microRNAs in key areas.

[CJ – Cytokines Not the Answer? - Note the two statements emphasizing that cytokine results are not consistent in ME/CFS, and that this research program includes cytokines but is mostly looking elsewhere. The infectious onset and the symptoms present in ME/CFS have suggested for over 30 years that cytokines must play a key role in this disorder, but outside of the Klimas/Fletcher lab the results have been variable. Perhaps the most intriguing cytokine finding came from the Dubbo studies suggesting that high cytokine levels early in an infection (but not later!) predicted who would come down with ME/CFS. The NCNED group is mostly looking elsewhere and may be looking deeper into the immune system, in particular NK cells, than any other group.]

Several researchers from the department then presented their work.

Ekua Brenu (Gold Coast, Australia) – Immune System Overview

Ekua Brenu (Gold Coast, Australia) discussed the immune system in ME/CFS. Due to inconsistencies the exact immunological mechanism remains unknown.

Reduced NK cell function worldwide is emerging as an important component. NK function declines further in these patients over time. There are reduced NK lytic proteins in ME/CFS (perforin, granzymeA and significant GranzymeB ). There is increased NK cell fragmentation and increased NK IFN?. The percentage of CD56+ and CD16- is down.

  • Dendritic cell subsets: MDCs slightly up and PDCs down.

  • Neutrophils: phagocytosis normal, but respiratory burst down. HNA’s variable with HNA2 down.

  • B cells: Immature down and memory and plasma cells slightly elevated.

  • T cell subsets focused on cytokine release. Longitudinal assessment was not consistent. Looking at T cell subsets: FoxP3 Tregs significantly elevated, CD39+T slightly elevated, CD73+T significantly elevated.

With CD8 lysis, NK activity and CD8 activity were significantly decreased. Molecular investigations identified significant decreases in MiRNAs that regulate cellular development and apoptosis.

[CJ – NK cells are surely not the be all and end all of ME/CFS, but note how many different facets of NK cell dysfunction are found:  reduced functioning (reduced killing capacity), high levels of ‘broken up’ or fragmented NK cells (because they’ve committed suicide (apoptosis)?), reduced types of NK cells, and, on a rather ominous note, the finding that NK cell functioning tends to decline over time.]

Sharni Hardcastle (Gold Coast, Australia) – Immunological Profile

Sharni Hardcastle (Gold Coast, Australia) outlined the immunological profile of ME/CFS.

She had examined innate immune cells. She explained that NK cells are protective and, in ME/CFS, show decreased cytotoxic activity. Exocytosis of perforin and granzymes leads to cell apoptosis. Studies by their group had studied the illness in severely affected patients, by visiting them in their homes to collect blood.

Using the new flow cytometer, they had been able to look at cell phenotypes and cytotoxic activity. NK cytotoxic activity in the severely ill was markedly down. Follow up with both moderately and severely ill patients showed that the NK activity in the severe remained significantly far worse. There was increase in NK phenotypes, variable KIR receptors, DC and B cell subsets and reduced perforin in CD8+Tcells compared to controls. She stressed the importance of looking at severity both clinically and in the laboratory.

[CJ- Several groups (including the CDC) are now making a special effort to examine the severely ill who are largely unable to make it to doctor’s offices or engage in studies.  This is the first report that I know of to come out of those efforts. The KIR receptors problems suggested their immune systems were more severely suppressed, and these patients’ T cells appeared to have the same malfunction that their NK cells did.]

Samantha Johnston (Gold Coast, Australia) – The Definition Question  

Samantha Johnston (Gold Coast, Australia) discussed the application of case definitions in ME/CFS research. She described the fact that there had been 8 case definitions used over the years, including 1988 Holmes, 1994 Fukuda and more recently the Canadian and then International criteria (ICC). Differences in symptoms and exclusion criteria lead to significant causes of variability. Prevalence using the Fukuda and Canadian criteria varied from 0.19% to 0.03%. Prevalence using the ICC has yet to be reported.

Initially definitions had emphasized fatigue and associated flu-like symptoms. More recent definitions describe an illness with neurological, immune and metabolic dysfunctions. The ICC is designed to be used in clinical settings, but if used in research, it could enable to identification of specific subgroups of the illness. Sensitivity and specificity, in relation to the 2011 International criteria has yet to be established.

[CJ - A recent study by the NCNED found more immune abnormalities, in particular those involving immune suppression, in patients meeting the ICC criteria compared to patients meeting the 1994 Fukuda or CDC criteria. About half the chronic fatigue syndrome patients that did not meet the ICC criteria but still had significant immune problems, suggested that both groups should be included in studies.]

Dan Peterson (Simmaron Research Foundation, Nevada, USA) - Diagnosis and Management

Dan Peterson (Simmaron Research Foundation, Nevada, USA) reviewed the diagnostic and management plan for patients with CFS/ME. He acknowledged that there is insufficient home and medical care for these patients. Prevalence worldwide may be as much as 19 million. The illness seems similar worldwide, but therapeutic responses differ widely.

Drug development can take up to 15 years, but a drug can be “repurposed”, and a biomarker is not necessarily required. Drug trials need to be large to be of value. Drugs can be “biomarkers” in themselves. (e.g., responses to cytokine blockers, immune modulators)

He then went on to discuss immune and antiviral therapies. Past trials have included immunoglobulins, Ampligen and Imunovir. Ampligen needs to be taken long term and is very expensive. Data extraction trials are however ongoing. With antivirals, some subsets respond well to Cidofovir. Valtrex (valgancyclovir) has been used for those who are HHV6 or EBV positive and there has been significant improvement. Other interventions include rituximab, cytokine blockers and GcMAF.

[Dr. Peterson’s assertion that a drug can be a ‘biomarker’ refers to the idea of segregating patients according to their response to treatment, and then digging into their physiology to uncover biomarkers that explain why they responded and others did not. Dr. Peterson’s presentation at the recent HHV-6 conference demonstrating that Cidofovir can be effective in some patients is an example of a possible treatment ‘biomarker’ that could be used to find other biomarkers. Dr. Kogelnik at the OMI and Fluge and Mella in Norway are exploring why some patients respond to Rituximab and/or antivirals.]

Kathy Rowe (Melbourne, Australia) - Prognosis for Adolescents with Chronic Fatigue Syndrome

Kathy Rowe (Melbourne, Australia) runs a large hospital based clinic in Melbourne and has seen many patients since 1991. She presented her work looking at the long term outcome in young people with ME/CFS. Attempts were made to contact 788 young people who had attended her clinic from 1991-2009. 82% (1200) forms were returned, providing feedback biannually. The questionnaire asked for a functional rating out of 10 and included such things as schooling, tertiary education, level of education, work, marriage, childbirth, etc.

Average duration of illness was 5 years (range 1-16 years) and at 5 years, 60% had recovered, and at 12 years, 88% had recovered. 1/3 said they had to consciously manage their workload. Of those recovered, some only rated their health at 8/10, but were leading relatively normal lives.

There were no differences relating to severity or age. Earlier diagnosis and helpful professionals had positive impact. Only 5% of those recovered were not working or studying, and this was often due to factors other than ME/CFS. 90% had completed their education, and a number were married with children. Rates of depression (usually due to not being well) were comparable to Victorian base rates. There was a better rate of recovery for those not depressed. Lack of parental bonding was not significant. 58% were EBV positive, and 20% had serological evidence of EBV infection at onset. 25% had significant ANA antibody titres, but this and positive EBV were no predictors of outcome. (10% went on to develop lupus). She questioned the significance of a positive ANA. But overall these results seem very good.

[CJ – Dr. Cheney, in particular, has referred to higher rates of recovery in adolescents than adults (and in a retrospective study dating back decades, Dr. Bell found that treatment made little difference in who recovered and who did not!).  Rowe finds high rates of very substantial recovery over a long period of time in this study. The fact that 1/3 of patients (after 12 years?) had to consciously manage their workloads for fear of getting sick again indicated their recoveries were not complete. However, the 88% recovery rate, the very high rates of engagement in work or study, and the ‘relatively normal lives’ they now lead indicated that very substantial recovery had occurred in most people who came down with ME/CFS as adolescents.]

Sarah Knight (Melbourne, Australia) – Children with ME/CFS

Sarah Knight (Melbourne, Australia) – reviewed the state of knowledge about ME/CFS and looked at future directions. She is a paediatric psychologist – part of a large team. She stressed the importance of not seeing children as little adults – there are many differences, including attention to developmental changes. There are more challenges ahead for children with CFS/ME. The illness is more common in females and in children over 10. There is significant school absenteeism. Presentations are often complex and heterogeneous. There is an average delay of 15.5 months from onset until they come to the clinic for diagnosis. Co-morbidities are common. The investigations done by the GPs are variable, but all the usual investigations are undertaken at the clinic. Translational research has led to the development of a clinical programme.

Rosamund Vallings (Auckland, NZ) – Educating Doctors

Rosamund Vallings (Auckland, NZ) gave an overview of the approach she takes to educate GPs further about how to diagnose and manage this illness. She pointed out that the average GP has a minimal grasp of immunology and biochemistry, and with time constraints (usually only 15 minute consultations) also finds this illness seemingly too complex to manage. But a very simplified approach to understanding can be taught in medical schools, to GPs in training and at CME sessions. The doctor may need to approach the illness over several short consultations.

Acknowledgement and then education of the patient and family are important issues once a tentative diagnosis has been established. Attention to symptom management (pain, sleep, orthostatic intolerance) can then follow in much the same way as one would manage any chronic illness. The doctor needs access to suitable handouts. The importance of ongoing surveillance, and referring onto other health professionals were stressed, as well as using on-site other professionals such as practice nurses, physiotherapists and psychologists. This illness should be managed in General Practice, but worldwide there is a shortage of doctors with the requisite knowledge, leading to lack of confidence in tackling this complex area of medicine.

Warren Tate (Dunedin, NZ) – Molecular Pathways in ME/CFS

Warren Tate (Dunedin, NZ) is working to provide understanding of the molecular pathways affected in ME/CFS. He stressed the importance of getting a predictive diagnostic test, and his team is working towards that. He is looking at pPKR and pIFalpha as potential predictive tests. He has been interested in a study that looked at the molecular changes in one person over 726 days. Following such changes in a ME/CFS patient over time and throughout relapses could be extremely valuable, but could be very expensive. He is also interested in the relationship to other fatigue syndromes and the different subclasses. He will also look at cytokines, microRNAs, DNA polymorphisms, metabolites etc. He has looked at the plasma microRNAs in Alzheimer’s disease, and the individual molecules were combined and analysed to provide a possible predictive model. This technique could be applied to CFS/ME. The closing addresses then followed.

Ross Humphreys, the chair of the NCNED steering committee spoke briefly and reiterated what a great day it had been, and what a wonderful event we had all witnessed with the opening of the facility.

Dr. Elizabeth Unger – Closing Address

He then introduced Elizabeth Unger (Atlanta, USA) to give the closing address. She said she had learnt a lot that day and had found it very exciting. She acknowledged that ME/CFS is a big public health problem, with epidemiology studies showing great economic impact. Interventions are needed such as education of the public, primary care physicians, nurses etc. Curricula are slowly developing. Many pathways are affected in this illness, and it needs to be dissected apart.

She asked the question as to whether we actually need a case definition, as it does not solve the problem of heterogeneity. We need validated questionnaires. No measures of outcome are readily available. A multisite review of the illness is needed, using a large number of measuring instruments.

She discussed the NIH funded PROMIS initiative (Patient Reported Outcomes Measurement Information System). 471 patients have completed questionnaires. There was less diversity than expected, and most respondents have been white upper class, educated people in the higher income bracket. Illness duration is seen as long. There were some symptoms reported by all, but a wide range of diversity. Results need to be combined with biomarkers, and the study is continuing. Results will also be compared with other illnesses such as Chronic Pain.

Christine Hunter then said a few words on behalf of the Alison Hunter Memorial Foundation (AHMF), and reiterated what we had all felt, that this was indeed a wonderful day. The AHMF now feel they have found a “home” and look forward to watching the development of the unit and ongoing research. Their contribution has resulted in installation of the flow cytometer, which will enable much exciting work to be undertaken.

The symposium was closed by Prof Donald Staines (Co-director of the NCNED)

CFS and GcMAF: 70%
Posted by: dnoakes
Dec 30, 2013
In 70% of cases, GcMAF eradicates 85% of CFS symptoms.

We have several hundred CFS cases on GcMAF with excellent outcomes, but we have a small, scientifically run trial where the results are measured accurately, and the above 70%/85% result is being achieved consistently.

People who have spent most of the last five years in bed have gone back to work.
