ME/CFS and Adferiad (Recovery) Long COVID

ME/CFS and Adferiad (Recovery) services

 

People in Wales, and further afield, have been expressing concern about plans to place ME/CFS services in existing Long COVID services. The Health Minister announced on the 14th March that there would be additional funding to widen access to Adferiad (Recovery) services to

“better support people with conditions such as ME/CFS and Fibromyalgia to get a diagnosis, manage their symptoms and access rehabilitation services”.

The name confusion

It is important to know that the Adferiad Recovery programme set up by substance abuse and mental health charities is NOT the same as the Welsh Government Adferiad (Recovery) programme for Long COVID. Each Health Board has set up a long COVID service based on common goals of the Adferiad programme which has been assessed regularly. So why do they have the same name? A VERY good question!

Is linking ME/CFS with other conditions a good idea?

We have been assured many times over the years by the Welsh Government and Health Boards that there is NO money for dedicated services. It was also clear that there had also been little will within NHS Wales to champion appropriate services for ME. Whether we like it or not long COVID has shone a light on ME and many with long COVID also meet the ME criteria, boosting numbers considerably and therefore adding to the need for services. [Research suggests 40 – 54% of people with long COVID have developed ME/CFS.]

There is an overlap in both symptoms and underlying dysfunction in ME/CFS, long COVID and Fibromyalgia. WAMES believes that people with ME triggered by COVID deserve a better service, just as people whose ME is triggered by other viruses and causes deserve to be recognised and offered services.

Diagnosis

Accurate diagnosis is where all good healthcare begins, whether that is diagnosis of a condition or acknowledgement of a symptom of unknown cause, that is disruptive to daily life.

All Heath Boards tell WAMES they are encouraging use of the 2021 ME/CFS NICE guideline in primary care. We don’t know yet how successful that is.

This is where you can help

  • Do you have a diagnosis? Is it recorded in your medical notes as ME/CFS?
  • Is it coded in the notes using SNOMED or READ or ICD codes?
  • If not, would you consider asking a GP if they agree with your suspicion that you have ME/CFS by checking it against the NICE guideline?

Until Health Boards know how many people there are living with ME in their area they can’t plan properly for services. They would probably be very surprised at how prevalent ME/CFS is these days!

Can a combined post-viral illness clinic work?

Only if everyone involved has a thorough understanding of the needs of each condition, are constantly updating their skills, if the pathways are clear, they take a patient-centred approach and there is appropriate management support for each condition.

WAMES has been asking Health Boards for their Service to include:

  • Assessment and care and support planning by an ME/CFS specialist team – as outlined at NICE 1.5
  • Managing ME/CFS and symptom management support – as outlined at NICE 1.11 onwards.

We believe that much that will help people with ME can also help people with other overlapping conditions. It would be churlish to refuse to share our hard earned knowledge! And maybe there are self-management approaches we can learn from others.

WAMES has met a number of health professionals throughout Wales who really want to push forward service development for ME/CFS but some have also observed that in their Health Board implementation of the full NICE guideline can only happen in stages, for a variety of reasons.

That is not ideal. However WAMES is keen to offer support to those willing to take the first steps and to keep speaking out where we believe service development continues to fail people with ME/CFS, to ensure the Welsh Government money really does begin to improve diagnosis, management and support for all with ME/CFS and PEM/PESE.

Research: ME/CFS is common in Long COVID patients

ME/CFS is common in PASC / long COVID

 

A US long COVID clinic found that 43% of PASC/ long COVID patients met the criteria for ME/CFS though they acknowledge that a larger more diverse group of patients might alter the figures.

“Fatigue, post-exertional malaise, brain fog, unrefreshing sleep, and daytime sleepiness were the most prevalent and severe symptoms. This commonality between ME/CFS and ME/CFS-PASC may suggest a shared pathobiology. Therefore, defining specific subtypes within the umbrella of PASC/post-COVID conditions can help us understand different pathogenic mechanisms to tailor treatment.”

Flow chart. *Positive SARC-CoV-2 test and over 28 days with symptoms. **Severe fatigue, unrefreshing sleep, PEM, and brain fog or orthostatic intolerance.

Research abstract:

Background:

The global prevalence of PASC is estimated to be present in 0·43 and based on the WHO estimation of 470 million worldwide COVID-19 infections, corresponds to around 200 million people experiencing long COVID symptoms. Despite this, its clinical features are not well-defined.

Methods:

We collected retrospective data from 140 patients with PASC in a post-COVID-19 clinic on demographics, risk factors, illness severity (graded as one-mild to five-severe), functional status, and 29 symptoms and principal component symptoms cluster analysis. The Institute of Medicine (IOM) 2015 criteria were used to determine the Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) phenotype.

Findings:

  • The median age was 47 years,
  • 59.0% were female;
  • 49.3% White, 17.2% Hispanic, 14.9% Asian, and 6.7% Black
  • Only 12.7% required hospitalization.
  • Seventy-two (53.5%) patients had no known comorbid conditions.
  • Forty-five (33.9%) were significantly debilitated. The median duration of symptoms was 285.5 days, and the number of symptoms was 12.

The most common symptoms were;

  • fatigue (86.5%),
  • post-exertional malaise (82.8%),
  • brain fog (81.2%),
  • unrefreshing sleep (76.7%), and
  • lethargy (74.6%).

Forty-three percent fit the criteria for ME/CFS, majority were female, and obesity (BMI > 30 Kg/m2) (P = 0.00377895) and worse functional status (P = 0.0110474) were significantly associated with ME/CFS.

Interpretations: Most PASC patients evaluated at our clinic had no comorbid condition and were not hospitalized for acute COVID-19.

One-third of patients experienced a severe decline in their functional status. About 43% had the ME/CFS subtype.

Research: Symptom-based clusters (sub-groups) in ME/CFS

Finding sub-groups in ME/CFS

 

Prof Leonard Jason worked with Dutch researchers to identify sub-groups of ME/CFS patients by symptom clusters. They used Leonard’s DePaul Symptom Questionnaire and data analysis software SOM. 45 subgroups were identified, some small. The researchers admit there are limitations with the study but have shown that sub-typing is possible.

“Classification of ME/CFS patients according to severity and symptoms patterns might be useful to develop tailored treatment options. Future studies are needed to investigate the relation between the identified symptom clusters and clinically relevant outcomes in patients with ME/CFS, including health-related quality of life and daily functioning.”

Symptom-based clusters in people with ME/CFS: an illustration of clinical variety in a cross-sectional cohort, by Anouk W Vaes, Maarten Van Herck, Qichen Deng, Jeannet M Delbressine, Leonard A Jason, Martijn A Spruit in J Transl Med. 2023 Feb 10;21(1):112 [doi: 10.1186/s12967-023-03946-6]

 

Research abstract

Background:

Myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) is a complex, heterogenous disease. It has been suggested that subgroups of people with ME/CFS exist, displaying a specific cluster of symptoms. Investigating symptom-based clusters may provide a better understanding of ME/CFS. Therefore, this study aimed to identify clusters in people with ME/CFS based on the frequency and severity of symptoms.

Methods:

Members of the Dutch ME/CFS Foundation completed an online version of the DePaul Symptom Questionnaire version 2. Self-organizing maps (SOM) were used to generate symptom-based clusters using severity and frequency scores of the 79 measured symptoms. An extra dataset (n = 252) was used to assess the reproducibility of the symptom-based clusters.

Results:

Data of 337 participants were analyzed (82% female; median (IQR) age: 55 (44-63) years). 45 clusters were identified, of which 13 clusters included ≥ 10 patients. Fatigue and PEM were reported across all of the symptom-based clusters, but the clusters were defined by a distinct pattern of symptom severity and frequency, as well as differences in clinical characteristics. 11% of the patients could not be classified into one of the 13 largest clusters. Applying the trained SOM to validation sample, resulted in a similar symptom pattern compared the Dutch dataset.

Conclusion:

This study demonstrated that in ME/CFS there are subgroups of patients displaying a similar pattern of symptoms. These symptom-based clusters were confirmed in an independent ME/CFS sample. Classification of ME/CFS patients according to severity and symptom patterns might be useful to develop tailored treatment options.

Welsh long COVID services to be opened up to ME/CFS & FM

Funding boost for services for long-term conditions

 

Health Minister Eluned Morgan has announced increased funding for Adferiad (long COVID) services. In 2022 she allocated £5m and this has now been raised to £8.3m for 2023. This will be shared between the 7 health boards in Wales to:

“widen access to Wales’ long-Covid services… to people with other long term conditions whose rehabilitation and recovery are similar – for example, people with myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS), fibromyalgia and other post-viral associated conditions.”

The Adferiad (Recovery) Services have been developed to: “provide diagnosis, treatment, rehabilitation, and care for people experiencing long-term effects of COVID-19. They have been designed to respond to the particular needs of each individual whilst providing care as close to home as possible. People are supported by multi-professional teams including psychologists, physiotherapists, occupational therapists and nurses. If more specialist care is needed, people can be referred for further help and support.”

The Health Minister said:  “We know many people with other, long term conditions have reported feeling ‘misunderstood’ and ‘invisible’. I hope by widening access to Adferiad (Recovery) services we can better support people with conditions such as ME/CFS and fibromyalgia to get a diagnosis, manage their symptoms and access rehabilitation services, which are vital in helping improve physical and mental health and wellbeing.”

WAMES has already begun talking to some health boards about how services based on the NICE guideline and pathway can be effectively incorporated into their existing service model, so that appropriate provision is made for people with PEM/PESE. We will keep you updated on opportunities to give feedback for your area. In the meantime, please pass on to jan@wames.org.uk any information or experiences that will help us explain what people with ME/CFS need from health and wellbeing services in Wales.

  • Do you have a diagnosis?
  • Does your current GP use NICE 2021 to guide her/him?
  • Are there services in your community which understand ME/CFS?

Research: Urine – another way to show inability to cope with exercise in ME/CFS

Urine shows abnormal reaction to exercise in ME/CFS

 

A small study of 8 women gave surprising results when their urine was examined after an exercise test and compared to healthy people.

“Our most unanticipated discovery is the lack of changes in the urine metabolome of ME/CFS patients during recovery while significant changes are induced in controls after CPET, potentially demonstrating the lack of adaptation to a severe stress in ME/CFS patients.”

“…significant differences were discovered between controls and ME/CFS patients in many lipid (steroids, acyl carnitines and acyl glycines) and amino acid subpathways (cysteine, methionine, SAM, and taurine; leucine, isoleucine, and valine; polyamine; tryptophan; and urea cycle, arginine and proline).”

To test the validity of these results researchers say that future studies should ensure BMI of participants is matched, diet is controlled and men are included.

 

Urine metabolomics exposes anomalous recovery after maximal exertion in female ME/CFS patients by Katherine A Glass, Arnaud Germain, Yuhsin V Huang and Maureen R Hanson in Int. J. Mol. Sci. 2023, 24(4), 3685;[doi.org/10.3390/ijms24043685]

Research abstract:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating disease with unknown etiology or effective treatments.

Post-exertional malaise (PEM) is a key symptom that distinguishes ME/CFS patients. Investigating changes in the urine metabolome between ME/CFS patients and healthy subjects following exertion may help us understand PEM.

The aim of this pilot study was to comprehensively characterize the urine metabolomes of eight female healthy sedentary control subjects and ten female ME/CFS patients in response to a maximal cardiopulmonary exercise test (CPET).

Each subject provided urine samples at baseline and 24 h post-exercise. A total of 1403 metabolites were detected via LC-MS/MS by Metabolon® including amino acids, carbohydrates, lipids, nucleotides, cofactors and vitamins, xenobiotics, and unknown compounds.

Using a linear mixed effects model, pathway enrichment analysis, topology analysis, and correlations between urine and plasma metabolite levels, significant differences were discovered between controls and ME/CFS patients in many lipid (steroids, acyl carnitines and acyl glycines) and amino acid subpathways (cysteine, methionine, SAM, and taurine; leucine, isoleucine, and valine; polyamine; tryptophan; and urea cycle, arginine and proline).

Our most unanticipated discovery is the lack of changes in the urine metabolome of ME/CFS patients during recovery while significant changes are induced in controls after CPET, potentially demonstrating the lack of adaptation to a severe stress in ME/CFS patients.

Orthostatic intolerance & chronotropic incompetence in ME

OI and CI in ME

 

Orthostatic intolerance and chronotropic incompetence in patients with Myalgic Encephalomyelitis or Chronic Fatigue Syndrome, by K Miwa in Circulation Reports 2023; 5: 55–61 [doi:10.1253/circrep.CR-22-0114]

Research abstract:

Orthostatic intolerance is a common symptom in ME/CFS, and the symptoms induced by sitting or standing can leave patients bedridden.

Chronotropic incompetence (CI) refers to the inability of the heart to increase its beat rate to a level that is proportionate to the activity being undertaken, or a reduced increase in heart rate during activity.

Previous studies have observed CI in ME/CFS patients. This study aimed to explore the role of POTS and CI in ME/CFS patients during orthostasis.

The recordings of 101 ME/CFS patients (International Consensus Criteria) who completed an active 10-minute standing test at least 3 times from July 2017 to December 2020 at the Miwa Naika Clinic (Japan) were included in this study.

This test involved recumbent rest for 5 minutes, and then standing with feet shoulder width apart for 10 minutes. Inability to reach 10 minutes was recorded as a failure, and postural orthostatic tachycardia syndrome (POTS), orthostatic hypotension or neurally mediated hypotension, were subsequently diagnosed depending on symptom and heart rate responses to the test.

CI was considered positive if a patient failed the test without POTS but, succeeded with POTS on other attempts.

The authors found that 13 participants completed standing tests with and without exhibiting POTS, whilst also completing and failing the test on different occasions. Of these patients, they were categorised as CI positive if test success occurred with POTS and test failure occurred without POTS being exhibited. Amongst these 13 patients, the authors found that 92% were CI positive, and 38% exclusively failed the test without experiencing POTS.

The authors conclude that these results demonstrate that the presence of POTS in ME/CFS patients is essential for the maintenance of orthostasis during 10-minute standing tests. The authors also conclude that some ME/CFS patients experience CI during standing tests, suggesting the presence of impaired sympathetic activation.

Research: Distinguishing ME/CFS & FM

Distinguishing ME/CFS and FM through gene expression

 

Canadian researchers have measured the activity (expression) of genes in people with ME/CFS and Fibromyalgia. 3 of the 11 miRNA were over-expressed in ME/CFS and under-expressed in FM. These three miRNAs could be used as potential biomarkers to distinguish ME/CFS from FM.

microRNA is the name of a family of molecules that helps cells control the kinds and amounts of proteins they make. That is, cells use microRNA to help control gene expression. Molecules of microRNA are found in cells and in the bloodstream. OSUCCC

Research abstract

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), and fibromyalgia (FM) are two chronic complex diseases with overlapping symptoms affecting multiple systems and organs over time. Due to the absence of validated biomarkers and similarity in symptoms, both disorders are misdiagnosed, and the comorbidity of the two is often unrecognized.

Our study aimed to investigate the expression profiles of 11 circulating miRNAs previously associated with ME/CFS pathogenesis in FM patients and individuals with a comorbid diagnosis of FM associated with ME/CFS (ME/CFS + FM), and matched sedentary healthy controls.

Whether these 11 circulating miRNAs expression can differentiate between the two disorders was also examined. Our results highlight differential circulating miRNAs expression signatures between ME/CFS, FM and ME/CFS + FM, which also correlate to symptom severity between ME/CFS and ME/CFS + FM groups.

We provided a prediction model, by using a machine-learning approach based on 11 circulating miRNAs levels, which can be used to discriminate between patients suffering from ME/CFS, FM and ME/CFS + FM.

These 11 miRNAs are proposed as potential biomarkers for discriminating ME/CFS from FM. The results of this study demonstrate that ME/CFS and FM are two distinct illnesses, and we highlight the comorbidity between the two conditions.

Proper diagnosis of patients suffering from ME/CFS, FM or ME/CFS + FM is crucial to elucidate the pathophysiology of both diseases, determine preventive measures, and establish more effective treatments.

The World ME Alliance & the WHO discuss disability health equity

The WMEA engages with the WHO over disability health equity

 

Following the World ME Alliance’s letter to the World Health Organization (WHO) highlighting critical gaps in their “Global report on health equity for persons with disabilities”, we have met with officials to discuss our recommendations.

This was a positive discussion on the importance of including those with energy limiting disabilities in global health responses. We discussed the range and severity of disability experienced by people with ME and other energy limiting disabilities, and the impact this can have on access to healthcare.

The WHO is now working to produce a Guide for Action, to help countries implement the recommendations set out in the “Global report on health equity for persons with disabilities”.

The World ME Alliance will continue to meet with WHO officials as this guide is developed, to ensure people with ME and other energy limiting disabilities are considered throughout.

We extend our thanks to Darryll Barrett (WHO Technical Lead for Disability), Dr Tarun Dua (Head of the Brian Health Unit), Dr Nicoline Schiess and Kaloyan Kamenov for a productive meeting, and look forward to ongoing work together.

This meeting was attended by the co-chairs of the World ME Alliance, Sonya Chowdhury and Oved Amitay, along with Sian Leary, our Head of Advocacy and Communications.

WAMES is an active member of the WMEA along with 20 other organisations around the globe

Research: Different risk factors distinguish ME/CFS from severe fatigue

Severe Fatigue is not the same as ME/CFS

 

US researchers led by Prof Komaroff found that severe fatigue was much more common than ME/CFS in a large group of nurses and the triggers were different. There was an increased risk of ME/CFS in people with a history of mononucleosis (or glandular fever).

Research abstract:

Fatigue is a common reason that patients seek medical care. Only a fraction of these patients meet criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

To determine if ME/CFS is just a more extreme form of fatigue, or a qualitatively different condition, we assessed whether risk factors for ME/CFS and for Severe Fatigue were similar. An email questionnaire that inquired about symptoms of Severe Fatigue and ME/CFS was completed by 41,802 US female nurses from whom detailed medical and lifestyle information had been collected since 1989.

  • 102 met criteria for ME/CFS
  • 522 had Severe Fatigue
  • 41,178 individuals were without significant chronic fatigue.

We used Cox proportional hazards regression to estimate the Hazard Ratio (HR) of Severe Fatigue and of ME/CFS with each of several potential risk factors, according to the level of exposure to each risk factor.

The risk of Severe Fatigue was significantly increased among

  • participants who were older,
  • had a higher BMI in adulthood,
  • used hormone therapy,
  • had increased alcohol intake
  • and decreased caffeine intake.

In contrast, these risk factor associations were not seen in people with ME/CFS. A self-reported past history of acute infectious mononucleosis was associated with a non-significantly increased Hazard Ratio of later ME/CFS (HR 1.77, 0.87–3.61) and, to a lesser extent, of Severe Fatigue (HR 1.28, 0.98–1.66).

The different contribution of various risk factors to Severe Fatigue and ME/CFS suggests that ME/CFS has a qualitatively different underlying biology from the more common state of Severe Fatigue.
