Research: COVID infection reactivates viruses more strongly in people with ME/CFS

Posted on 11/02/2022 by wames

COVID reactivates viruses in ME/CFS

 

Swedish researchers searched for viruses in the blood and saliva of 95 non-vaccinated ME/CFS patients and 110 healthy people following a Covid-19 infection. Dormant viruses in both groups were reactivated, but more strongly in the saliva of ME/CFS patients i.e. herpesviruses (EBV, HHV6) and endogenous retrovirus (HERV-K). ME/CFS patients are more susceptible and have stronger reactions to a Covid-19 infection. This provides further evidence for altered immune responses in ME/CFS.

Saliva antibody-fingerprint of reactivated latent viruses after mild/ asymptomatic COVID-19 is unique in patients with myalgic-encephalomyelitis/ chronic fatigue syndrome, by Eirini Apostolou, Muhammad Rizwan, Petros Moustardas, Per Sjögren, Bo Christer Bertilson, Björn Bragée, Olli Polo and Anders Rosén in Front. Immunol., 20 October 2022 [doi.org/10.3389/fimmu.2022.949787]

Research abstract:

Background:

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic disease considered to be triggered by viral infections in a majority of cases. Symptoms overlap largely with those of post-acute sequelae of COVID-19/long-COVID implying common pathogenetic mechanisms. SARS-CoV-2 infection is risk factor for sustained latent virus reactivation that may account for the symptoms of post-viral fatigue syndromes.

The aim of this study was first to investigate whether patients with ME/CFS and healthy donors (HDs) differed in their antibody response to mild/asymptomatic SARS-CoV-2 infection. Secondly, to analyze whether COVID-19 imposes latent virus reactivation in the cohorts.

Methods: 

Anti-SARS-CoV-2 antibodies were analyzed in plasma and saliva from non-vaccinated ME/CFS (n=95) and HDs (n=110) using soluble multiplex immunoassay. Reactivation of human herpesviruses 1-6 (HSV1, HSV2, VZV, EBV, CMV, HHV6), and human endogenous retrovirus K (HERV-K) was detected by anti-viral antibody fingerprints in saliva.

Results:

At 3-6 months after mild/asymptomatic SARS-CoV-2 infection, virus-specific antibodies in saliva were substantially induced signifying a strong reactivation of latent viruses (EBV, HHV6 and HERV-K) in both cohorts. In patients with ME/CFS, antibody responses were significantly stronger, in particular EBV-encoded nuclear antigen-1 (EBNA1) IgG were elevated in patients with ME/CFS, but not in HDs. EBV-VCA IgG was also elevated at baseline prior to SARS-infection in patients compared to HDs.

Conclusion: 

Our results denote an altered and chronically aroused anti-viral profile against latent viruses in ME/CFS. SARS-CoV-2 infection even in its mild/asymptomatic form is a potent trigger for reactivation of latent herpesviruses (EBV, HHV6) and endogenous retroviruses (HERV-K), as detected by antibody fingerprints locally in the oral mucosa (saliva samples). This has not been shown before because the antibody elevation is not detected systemically in the circulation/plasma.

Comments:

Believed and safe: A new discovery about enigmatic fatigue

“The bottom line then is that patients with ME/CFS are more sensitive and have much stronger reactions to a mild COVID-19 infection. Their dormant virus is awakened and chews up the energy and the result is more fatigue, more exhaustion and feverishness, rather than typical flu symptoms… Time and again, the power plants are shut down. And you get worse general condition and poorer immune system. Not only has it been infected by a new virus, it has also awakened an army of sleeping past sinners who are being reactivated.”

MEA: Comment

“I do hope these results are followed up, as these findings have the potential for the development of new treatments looking at boosting the antiviral immune response as well as a role in immunological tests for diagnosis.”

Doctors use more negative language about ME/CFS online than other illnesses

Posted on 10/31/2022 by wames

Doctors’ attitudes to medical conditions

 

On an online medical forum physicians were found to discuss ME/CFS, depression and Lyme disease with more negative language than 21 other diseases. The results for ME/CFS included over 4 times more negative words than the results for depression.

 

Doctors’ attitudes toward specific medical conditions, by Brooke Scoles, Catia Nicodemo in Journal of Economic Behavior & Organization Vol 204, Dec 2022, pp 182-199 [doi.org/10.1016/j.jebo.2022.09.023]

Research abstract:

This study uses machine learning and natural language processing tools to examine the language used by healthcare professionals on a global online forum. It contributes to an underdeveloped area of knowledge, that of physician attitudes toward their patients.

Using comments left by physicians on Reddit’s “Medicine” subreddit (r/medicine), we test if the language from online discussions can reveal doctors’ attitudes toward specific medical conditions. We focus on a set of chronic conditions that usually are more stigmatized and compare them to ones well accepted by the medical community.

We discovered that when comparing diseases with similar traits, doctors discussed some conditions with more negative attitudes. These results show bias does not occur only along the dimensions traditionally analyzed in the economics literature of gender and race, but also along the dimension of disease type.

This is meaningful because the emotions associated with beliefs impact physicians’ decision making, prescribing behavior, and quality of care.

First, we run a binomial LASSO-logistic regression to compare a range of 21 diseases against myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), depression, and the autoimmune diseases multiple sclerosis and rheumatoid arthritis. Next, we use dictionary methods to compare five more chronic diseases: Lyme disease, Ehlers-Danlos syndrome (EDS), Alzheimer’s disease, osteoporosis, and lupus.

The results show physicians discuss ME/CFS, depression, and Lyme disease with more negative language than the other diseases in the set. The results for ME/CFS included over four times more negative words than the results for depression

The role of mental health practitioners for Long COVID & ME/CFS

Posted on 10/24/2022 by wames

A new challenge: mental health practitioners can learn from ME/CFS when supporting the long-term effects of COVID-19

 

A research paper from a team of researchers including Prof Leonard Jason and Dr Nina Muirhead believes that:

Mental Health Practitioners (MHPs) have a unique opportunity to provide resources and support to those suffering from Long COVID (LC), the post infectious illness that often follows an acute SARS-CoV-2 infection.

In working with these individuals, MHPs can learn from the experiences of patients with another post-infectious disease known as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

ME/CFS was once thought to be a psychologically mediated disorder caused by deconditioning and the fear of exertion following a precipitating event such as a viral infection.

Research now shows that LC and ME/CFS are biomedical, multisystem, complex physiologic diseases. This article provides a framework to MHPs for the treatment of LC patients using knowledge derived from three decades of research on ME/CFS.

The paper includes information on the role of mental health therapists:

  • Understanding the illness.
  • Proper interviewing when considering biomedical and/or psychological diagnosis.
  • Proper interviewing when considering biomedical and/or psychological diagnosis.
  • Proper interviewing when considering biomedical and/or psychological diagnosis.
  • Proper interviewing when considering biomedical and/or psychological diagnosis.
  • When to refer to psychopharmacology.

Mental Health Practitioners can offer support with:

  • Coping
  • Post-exertional malaise (PEM) and pacing
  • Sleep disturbances
  • Dealing with individuals unfamiliar with LC or ME/CFS
  • Role of social media and support

World ME Alliance asks WHO to recognise ME

Posted on 10/19/2022 by wames

World ME Alliance calls on WHO Director General to recognise ME alongside Long Covid

 

On Wednesday 12th October Dr Tedros Ghebreyesus, Director General of the World Health Organization, wrote an op-ed in the Guardian. In it, he lays clear the devastation that Long Covid is causing around the world and sets out five key elements of a plan to drive change.

It is vital that the impact of Long Covid is recognised at the highest levels, and the World ME Alliance congratulates Dr Ghebreyesus on this stance.

However, as more research is undertaken, it is becoming clearer that a large proportion of those with Long Covid now meet the criteria for an ME/CFS diagnosis. The WHO must recognise this as efforts to find treatments and a cure continue.

The World ME Alliance has written to Dr Ghebreyesus calling on him to meet with representatives.

Dr Ghebreyesus has previously committed to reaching out to ME experts, and we hope that through collaborative efforts we can learn from ME and ensure that progress for people with Long Covid doesn’t leave the millions already suffering with ME behind.

Read the full letter from the World ME Alliance and its 19 members, which includes WAMES, representing Wales.

 

Dear Dr Ghebreyesus,

Our World ME Alliance read your recent Guardian article “The data is clear: long Covid is devastating people’s lives and livelihoods” with great interest.

We would like to congratulate you and the World Health Organization for taking this issue so seriously. In particular, we appreciate your acknowledgement of the devastation Long Covid is causing, the need to listen to patient groups, and the need for sustained investment to expand our scientific understanding so better treatments and clinical management can be developed.

While we congratulate the efforts to innovate around Long Covid, we also see that people with myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS), many of whom have already suffered decades of the same devastation you have described, face a lack of recognition and global response.

The most prevalent Long Covid symptoms — crippling fatigue, post-exertional malaise, widespread inflammation, and cognitive dysfunction — mirror those of ME/CFS. As more research is undertaken, it is becoming clearer that a large proportion of those with Long Covid now meet the criteria for an ME/CFS diagnosis, also known to be a viral-associated disease.

Additionally, many studies1, 2, 3, 4, 5 are making key scientific connections between ME/CFS and Long Covid.

This is not new. Outbreaks of viruses such as swine flu (H1N1) and Ebola, as well as common viruses including Epstein-Barr Virus (EBV), demonstrate that chronic illness triggered by viral infections, including ME/CFS, are a recurrent phenomenon.

We would welcome a meeting with you to follow up on past commitments to establish contact with ME/CFS experts and patient organisations. We believe this could fast track support for people with ME/CFS and also those with Long Covid, ensuring learnings from ME/CFS are taken advantage of, and that progress for people with Long Covid doesn’t leave those with ME/CFS behind.

Yours sincerely,
Sonya Chowdury, Co-Chair of the World ME Alliance, CEO of Action for M.E.

Research: DNA changes during a relapse and recovery cycle in ME/CFS

Posted on 10/17/2022 by wames

Dynamic epigenetic changes during a relapse and recovery cycle in Myalgic Encephalomyelitis/ Chronic Fatigue Syndrome

 

Epigenetics is the study of how your behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence. (CDC)

A New Zealand research team led by Prof Warren Tate explored changes in the genes of 2 patients with ME/CFS during a relapse which resulted in “functionally important changes in their DNA methylomes that, while differing between the two patients, led to very similar compromised physiology.

 

Conclusions
This study shows the benefits of precision medicine for individual patients with a disease as physiologically complex as ME/CFS.

Precision medicine – an emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person. (NLH)

Currently, ME/CFS patients can respond quite differently to specific medications, for example supplements like vitamin B12, and to anti-inflammatory drugs like naltrexone, and to physiological states like pregnancy, with some showing marked improvement, some marked deterioration, and some seemingly no change in their condition.

By considering individual patients over the course of their ME/CFS disease we can better understand not only the similarities within the overall patient group, but also develop an in depth understanding of the fluctuations for each patient that relates to their specific pathophysiology.

Variable methylation of regulatory regions associated with the relapse condition has in this study identified a number of genes with key functional roles in immune, inflammatory, metabolic and mitochondrial pathways.

For a disease that has proven challenging to diagnose and characterise, with the delay in diagnosis detrimental for the affected person, this kind of analysis provides not only further evidence of serious biological dysfunction, but importantly also ongoing systematic molecular changes that inform future targets for individual treatment or symptom management as we continue to unravel and understand the complex nature of ME/CFS.

Dynamic Epigenetic Changes during a Relapse and Recovery Cycle in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, by Amber M Helliwell, Peter A Stockwell, Christina D Edgar, Aniruddha Chatterjee, Warren P Tate in Int J Mol Sci. 2022 Oct 6;23(19):11852 [doi: 10.3390/ijms231911852]

Research abstract:

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex disease with variable severity. Patients experience frequent relapses where symptoms increase in severity, leaving them with a marked reduction in quality of life.

Previous work has investigated molecular differences between ME/CFS patients and healthy controls, but not the dynamic changes specific to each individual patient. We applied precision medicine here to map genomic changes in two selected ME/CFS patients through a period that contained a relapse recovery cycle.

Method

DNA was isolated from two patients and a healthy age/gender matched control at regular intervals and captured the patient relapse in each case. Reduced representation DNA methylation sequencing profiles were obtained spanning the relapse recovery cycle. Both patients showed a significantly larger methylome variability (10-20-fold) through the period of sampling compared with the control.

Results

During the relapse, changes in the methylome profiles of the two patients were detected in regulatory-active regions of the genome that were associated, respectively, with 157 and 127 downstream genes, indicating disturbed metabolic, immune and inflammatory functions.

Severe health relapses in the ME/CFS patients resulted in functionally important changes in their DNA methylomes that, while differing between the two patients, led to very similar compromised physiology.

DNA methylation as a signature of disease variability in ongoing ME/CFS may have practical applications for strategies to decrease relapse frequency.

Research: Orthostatic Intolerance & neurocognitive impairment overlap in ME/CFS

Posted on 10/13/2022 by wames

Orthostatic Intolerance & neurocognitive impairment overlap in ME/CFS

 

Prof Jason Leonard and US colleagues investigated the relationship between Orthostatic Intolerance and neurocognitive impairment in ME/CFS

Orthostatic intolerance (OI) is the development of symptoms when standing upright that are relieved when reclining (Wikipedia)

Conclusions

Neurocognitive symptoms and OI overlap in ME/CFS, and our results do not support the IOM’s inclusion of neurocognitive impairment and OI as interchangeable symptoms. Furthermore, our findings highlight the need for a uniform method of defining and measuring OI via self-report in order to accurately study OI as a symptom of ME/CFS.

Neurocognitive domains. The DSM-5 defines 6 key domains of cognitive function – Sachdev et al

 

Orthostatic intolerance and neurocognitive impairment in Myalgic Encephalomyelitis/ Chronic Fatigue Syndrome (ME/CFS), by Caroline L Gaglio, Mohammed F Islam, Joseph Cotler and Leonard A Jason in Epidemiologic Methods October 10, 2022 [doi.org/10.1515/em-2021-0033]

Research abstract

Objectives
The Institute of Medicine (IOM 2015. Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Redefining an Illness. Washington: The National Academies Press) suggested new criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), which requires an endorsement of either neurocognitive impairment or orthostatic intolerance (OI) in addition to other core symptoms.

While some research supports the inclusion of OI as a core symptom, others argue that overlap with neurocognitive impairment does not justify the either/or option. The current study assessed methods of operationalizing OI using items from the DePaul Symptom Questionnaire (DSQ-1 and -2) as a part of the IOM criteria. Evaluating the relationship between OI and neurocognitive symptoms may lead to a better understanding of diagnostic criteria for ME/CFS.

Methods
Two-hundred and forty-two participants completed the DSQ. We examined how many participants met the IOM criteria while endorsing different frequencies and severities of various OI symptoms.

Results
Neurocognitive impairment was reported by 93.4% of respondents. OI without concurrent neurocognitive symptoms only allowed for an additional 1.7–4.5% of participants to meet IOM criteria.

Conclusions
Neurocognitive symptoms and OI overlap in ME/CFS, and our results do not support the IOM’s inclusion of neurocognitive impairment and OI as interchangeable symptoms.

Furthermore, our findings highlight the need for a uniform method of defining and measuring OI via self-report in order to accurately study OI as a symptom of ME/CFS.

Research review: Genetics of COVID-19 & ME/CFS

Posted on 10/11/2022 by wames

Genetics of COVID-19 and ME/CFS: a systematic review

 

Greek researchers found 71 studies for COVID-19 and 26 studies for ME/CFS that looked at genes. They concluded:

Venn diagram regarding the significant genes of COVID-19 and ME/CFS.

“In spite of the fact that COVID-19 and ME/CFS present with some similar symptoms, especially physical and mental fatigue, genetic association, and cohort studies indicate that these two complex diseases share only a few common genes. These… appear to be involved in the regulation of immune processes.

This finding supports the notion that the pathogenesis of both syndromes may derive from some aberrant and lasting immune response, possibly involving mast cells and microglia, which have been recently implicated in both diseases.

Understanding the basis of this immune dysfunction could help with the diagnosis, prognosis, and treatment of these debilitating conditions.

 

Genetics of COVID-19 and myalgic encephalomyelitis/chronic fatigue syndrome: a systematic review, by Maria Tziastoudi, Christos Cholevas, Ioannis Stefanidis, Theoharis C Theoharides in Ann Clin Transl Neurol. 2022 Oct 6 [doi: 10.1002/acn3.51631]

Review abstract:

COVID-19 and ME/CFS present with some similar symptoms, especially physical and mental fatigue. In order to understand the basis of these similarities and the possibility of underlying common genetic components, we performed a systematic review of all published genetic association and cohort studies regarding COVID-19 and ME/CFS and extracted the genes along with the genetic variants investigated.

We then performed gene ontology and pathway analysis of those genes that gave significant results in the individual studies to yield functional annotations of the studied genes using protein analysis through evolutionary relationships (PANTHER) VERSION 17.0 software. Finally, we identified the common genetic components of these two conditions.

Seventy-one studies for COVID-19 and 26 studies for ME/CFS were included in the systematic review in which the expression of 97 genes for COVID-19 and 429 genes for ME/CFS were significantly affected. We found that ACE, HLA-A, HLA-C, HLA-DQA1, HLA-DRB1, and TYK2 are the common genes that gave significant results.

The findings of the pathway analysis highlight the contribution of inflammation mediated by chemokine and cytokine signaling pathways, and the T cell activation and Toll receptor signaling pathways. Protein class analysis revealed the contribution of defense/immunity proteins, as well as protein-modifying enzymes. Our results suggest that the pathogenesis of both syndromes could involve some immune dysfunction.

Research: Fitbit trackers & PROMs help monitor ME/CFS activity

Posted on 09/29/2022 by wames

Activity monitoring and patient-reported outcome measures in ME/CFS patients

A small Norwegian study from the team led by Prof Olav Mella and Dr Oystein Fluge trialled wearable activity trackers and questionnaires to monitor heart rate and activity to aid pacing for people with ME/CFS:

In this study we have observed the course of 27 ME/CFS patients during 6 months’ follow-up without any intervention. It is feasible to use activity trackers for the continuous registration of steps and resting heart rate in a study with ME/CFS patients.

According to feedback from patients, the Fitbit trackers were easy to use, and gave a fair reflection of their physical activity levels…

PROMs – self-report questionnaires which measure the severity or impact of symptoms [MEpedia]

After exploring different combinations of PROMs, activity measures and clinical assessment, we found that the combination of lower SF36-PF and higher DSQ-SF defined patients with more stable symptoms during follow-up in this study with no intervention.

The knowledge from this study could be useful for the design of study protocols and assessments of outcome measures in future interventional studies. We propose including a run-in period with activity tracking and PROMs pre-intervention to evaluate normal fluctuations of the disease in individual patients.

Due to the complexity of symptoms, it is necessary to combine the activity measures with patient-reported outcome measures to assess different aspects of disease.

Research article:

Activity monitoring and patient-reported outcome measures in Myalgic Encephalomyelitis/ Chronic Fatigue Syndrome patients, by Ingrid G Rekeland, Kari Sorland, Ove Bruland, Kristin Risa, Kine Alme, Olav Dahl, Karl J Tronstad, Olav Mella, Oystein Fluge in PLoS One Vol 17, #9, Sep 19, 2022

Research abstract:

Introduction

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disease with no validated specific and sensitive biomarker, and no standard approved treatment. In this observational study with no intervention, participants used a Fitbit activity tracker. The aims were to explore natural symptom variation, feasibility of continuous activity monitoring, and to compare activity data with patient reported outcome measures (PROMs).

Materials and methods

In this pilot study, 27 patients with mild to severe ME/CFS, of mean age 42.3 years, used the Fitbit Charge 3 continuously for six months.

Patients wore a SenseWear activity bracelet for 7 days at baseline, at 3 and 6 months. At baseline and follow-up they completed the Short Form 36 Health Survey (SF-36) and the DePaul Symptom Questionnaire-Short Form (DSQ-SF).

Results

The mean number of steps per day decreased with increasing ME/CFS severity; mild 5566, moderate 4991 and severe 1998. The day-by-day variation was mean 47% (range 25%-79%). Mean steps per day increased from the first to the second three-month period, 4341 vs 4781 steps, p=0.022.

The maximum differences in outcome measures between 4-week periods (highest vs lowest), were more evident in a group of eight patients with milder disease (baseline SF-36 PF>50 or DSQ-SF<55) as compared to 19 patients with higher symptom burden (SF-36 PF<50 and DSQ-SF>55), for SF-36 PF raw scores: 16.9 vs 3.4 points, and for steps per day: 958 versus 479 steps.

The correlations between steps per day and self-reported SF-36 Physical function, SF-36 Social function, and DSQ-SF were significant. Fitbit recorded significantly higher number of steps than SenseWear. Resting heart rates were stable during six months.

Conclusion

Continuous activity registration with Fitbit Charge 3 trackers is feasible and useful in studies with ME/CFS patients to monitor steps and resting heart rate, in addition to self-reported outcome measures.
