Research abstract:

Prevalence and correlates of low mood, poor quality of life and high symptom impact in adolescents attending a tertiary service for chronic fatigue syndrome/myalgic encephalomyelitis, by FK Neale, TY Segal, DS Hargreaves in Archives of Disease in Childhood Vol 103, Suppl 1, G13, March 2018

Background:
Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is a condition characterised by persistent fatigue that reduces activity and affects everyday life. It is associated with mood disorders, such as depression and anxiety, and a reduction in quality of life.

Aims:
This project describes the demographic of adolescents with CFS/ME being treated at a specialist service and their mood, quality of life and symptom impact. It assesses whether sex, age, Body Mass Index, household income and illness duration are associated with low mood, poor quality of life and greater symptom impact. It investigates the similarity
between the adolescents’ and their parents’ views of the impact of CFS/ME.

Methods:
69 adolescents, (10.4-18.0 years), were assessed at their initial clinic appointment using a three-part questionnaire. Their parents received one part of this questionnaire separately. The questionnaire was comprised of three survey instruments which had been previously validated for use in adolescents. Additional data about the adolescents was collected from
their clinic assessment form.

Results:
69.6% of the adolescents were female, 13.0% were obese or very obese and mean illness duration was 25.3 months. 36.2% of the adolescents came from a household within the 10% most affluent in the country. Moderate, severe or extreme anxiety or depression symptoms were reported by 39.1%, severe levels of worry by 43.5% and high or very high symptom impact by 69.1%. Long illness duration was significantly associated with low mood (p=0.006) but no other associations were significant. There was minimal  agreement between the adolescents’ and parents’ answers (mean kappa score=0.373) with the parents reporting CFS/ME to cause greater difficulties.

Conclusions:
Adolescents from high-income backgrounds are over-represented amongst adolescents attending this specialist clinic. This may represent higher prevalence or greater access to specialist services in high-income families. More than a third of adolescents attending this clinic reported significantly reduced quality of life and/or low or anxious mood symptoms; more than two thirds reported that the condition has a major impact on their daily life. Parents report CFS/ME to cause greater difficulties than their children do.

Research abstract:

Immunoadsorption to remove ß2 adrenergic receptor antibodies in Chronic Fatigue Syndrome CFS/ME, by Carmen Scheibenbogen, Madlen Loebel, Helma Freitag, Anne Krueger, Sandra Bauer, Michaela Antelmann, Wolfram Doehner, Nadja Scherbakov, Harald Heidecke, Petra Reinke, Hans-Dieter Volk, Patricia Grabowski in PLoS One. 2018 Mar 15;13(3):e0193672

INTRODUCTION:
Infection-triggered disease onset, chronic immune activation and autonomic dysregulation in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) point to an autoimmune disease directed against neurotransmitter receptors. We had observed elevated autoantibodies against ß2 adrenergic receptors, and muscarinic 3 and 4 acetylcholine receptors in a subset of patients. Immunoadsorption (IA) was shown to be effective in removing autoantibodies and improve outcome in various autoimmune diseases.

METHODS:
10 patients with post-infectious CFS/ME and elevated ß2 autoantibodies were treated with IA with an IgG-binding column for 5 days. We assessed severity of symptoms as outcome parameter by disease specific scores. Antibodies were determined by ELISA and B cell phenotype by flow cytometry.

RESULTS:
IgG levels dropped to median 0.73 g/l (normal 7-16 g/l) after the 4th cycle of IA, while IgA and IgM levels remained unchanged. Similarly, elevated ß2 IgG antibodies rapidly decreased during IA in 9 of 10 patients. Also 6 months later ß2 autoantibodies were significantly lower compared to pretreatment. Frequency of memory B cells significantly decreased and frequency of plasma cells increased after the 4th IA cycle. A rapid improvement of symptoms was reported by 7 patients during the IA. 3 of these patients had long lasting moderate to marked improvement for 6-12+ months, 2 patients had short improvement only and 2 patients improved for several months following initial worsening.

CONCLUSIONS:
IA can remove autoantibodies against ß2 adrenergic receptor and lead to clinical improvement. B cell phenotyping provides evidence for an effect of IA on memory B cell development. Data from our pilot trial warrants further studies in CFS/ME.

On CFS & nosological categories (historical review of CFS & relationship to other conditions)

Research abstract:

On chronic fatigue syndrome and nosological categories, by Sharif K, Watad A, Bragazzi NL, Lichtbroun M, Martini M, Perricone C, Amital H, Shoenfeld Y. in Clin Rheumatol. 2018 Feb 7.  [Epub ahead of print]

Chronic fatigue syndrome (CFS) is a heterogeneous disease which presents with pronounced disabling fatigue, sleep disturbances, and cognitive impairment that negatively affects patients’ functional capability. CFS remains a poorly defined entity and its etiology is still in question. CFS is neither a novel diagnosis nor a new medical condition. From as early as the eighteenth century, a constellation of perplexing symptoms was observed that resembled symptoms of CFS.

Commencing with “febricula” and ending with CFS, many names for the disease were proposed including neurocirculatory asthenia, atypical poliomyelitis, Royal Free disease, effort syndrome, Akureyri disease, Tapanui disease, chronic Epstein-Barr virus syndrome, and myalgic encephalitis. To date, it remains unclear whether CFS has an autoimmune component or is a condition that precedes a full-blown autoimmune disease.

Research suggests that CFS may overlap with other diseases including postural orthostatic tachycardia syndrome (POTS), autoimmune syndrome induced by adjuvants (ASIA), and Sjögren’s syndrome. Additionally, it has been postulated that the earliest manifestations of some autoimmune diseases can present with vague non-specific symptoms similar to CFS.

Sometimes only when exposed to a secondary stimulus (e.g., antigen) which could accelerate the natural course of the disease would an individual develop the classic autoimmune disease. Due to the similarity of symptoms, it has been postulated that CFS could simply be an early manifestation of an autoimmune disease. This paper will provide a historical background review of this disease and a discussion of CFS as an entity overlapping with multiple other conditions.

Functional status & well-being in people with ME/CFS compared with people with MS & healthy controls

Posted on 03/15/2018 by wames

Research abstract:

Functional Status and Well-Being in People with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Compared with People with Multiple Sclerosis and Healthy Controls, by Caroline C. Kingdon, Erinna W. Bowman, Hayley Curran, Luis Nacul, Eliana M. Lacerda in PharmacoEconomics Open 2018 pp 1-12  [Online: 13 March 2018]

Background:
People with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) continue to struggle to have their condition recognised as disabling in the face of public and professional prejudice and discrimination.

Objective:
The aim of this study was to compare the functional status and well-being of people with well-characterised ME/CFS with people with multiple sclerosis (PWMS), as well as healthy controls (HCs).

Methods:
In this cross-sectional study, we used data collected as part of the UK ME/CFS Biobank to compare actual participant scores from the Medical Outcomes Survey Short Form-36 v2™ (SF-36v2™) between groups, as a proxy for impact of disability, and from a bespoke questionnaire seeking data on employment and income.

Results:
People with ME/CFS scored significantly lower than PWMS or HCs in almost all SF-36v2™ areas. Prominent were lower scores for people with ME/CFS in the Physical Component Summary and Role Physical and Social Function domains, while the smallest differences were seen in the Mental Health domain. Responses to the bespoke questionnaire indicated that people with ME/CFS in this study work fewer hours and have lower incomes compared with people in the other two groups.

Conclusions:
Using SF-36v2™ scores as a proxy, people with ME/CFS were measurably more disabled than PWMS or HCs in this study population. Furthermore, employment and income data are consistent with loss of functional status. These findings should encourage the health community to recognise the disabling effects of ME/CFS, to advocate for the needs of people with ME/CFS, and to investigate strategies to address the cost of the disease to both individuals and society.

Key Points for Decision Makers:

  • This study suggests that at a group level people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) are more disabled than people affected by multiple sclerosis (MS), as measured by the SF-36v2™.
  • ME/CFS is associated with a reduction in time spent at work and lower income, compared with people affected by MS.
  • Further efforts should be made to identify and address the impact of ME/CFS to individuals and society.

Treating patients suffering from (ME/CFS) with sodium dichloroacetate: a pilot trial

Posted on 03/14/2018 by wames

Research abstract:

Treating patients suffering from myalgic encephalopathy/chronic fatigue syndrome ME/CFS) with sodium dichloroacetate: An open-label, proof-of-principle pilot trial, by Frank Comhaire in Medical hypotheses May 2018 Vol 114, Pp 45–48

Twenty-two consecutive patients suffering from refractory myalgic encephalitis/chronic fatigue syndrome (ME/CFS) were treated with an innovative nutriceutical containing sodium dichloroacetate in a proof-of-principle, pilot, open-label prospective cohort trial.

Ten patients experienced significant improvement of their health condition with reduction to almost half of their score in the fatigue severity scale. In twelve patients treatment failed to exert any beneficial effect. In the latter patients several other diseases have commonly been revealed by extensive biological and imaging investigations.

These preliminary findings sustain the hypothetical role of mitochondrial hypo-metabolism due to inhibition of the activity of the pyruvate dehydrogenase in the pathogenesis of primary ME/CFS, and suggest a possible benefit of nutriceutical treatment by sodium dichloroacetate.

Managing fatigue in postural tachycardia syndrome (PoTS): The Newcastle approach

Posted on 03/13/2018 by wames

Managing fatigue in postural tachycardia syndrome (PoTS): The Newcastle approach, Victoria Strassheim, Jenny Welford, Rob Ballantine, Julia L Newton in Auton Neurosci. 2018 Feb 22. pii: S1566-0702(17)30328-4 [Epub ahead of print]

Highlights:

  • Fatigue is a common symptom described by those with PoTS.
  • Chronic Fatigue Syndrome is often co-diagnosed with PoTS.
  • Management of fatigue in PoTS is best delivered as a multidisciplinary approach.

Research abstract:

Fatigue is a significant symptom that is frequently reported by those with postural tachycardia syndrome (PoTS). There are a variety of reasons why those with PoTS might experience fatigue and as a consequence an individualised approach to management is most appropriate.

In this chapter we will examine the prevalence of fatigue in those with PoTS, its overlap with conditions such as chronic fatigue syndrome and describe a clinical approach to the management of fatigue in those with PoTS.

Extract:

Managing fatigue
Managing fatigue is possible, but it is not easy. It takes commitment, persistence, trial and error with no immediate quick fix. There is no medication that will cure fatigue in general, or specifically in those with PoTS and a multi-disciplinary approach is needed to aid its management.

First, it is important to find a stable start point. In our fatigue clinic, in Newcastle UK (Hackett et al., 2016; Lambson et al., 2015) we frequently ask people to complete activity diaries and to grade whether their activities are high, medium or low, defining periods when they are resting or asleep. When people do this, they can often see patterns in their activity that highlight how they may be booming and busting, or pacing their activity appropriately.

The management booklet that we use in Newcastle is available via http://www.ncl.ac.uk/medicalsciences/research/centres/fatigue/, and the components of our multidisciplinary approach shown in Fig. 2.

When managing fatigue in PoTS patients, much of the advice that we use in our clinical practice is generic and some extrapolated from information available in the CFS literature (Chronic Fatigue Syndrome/ Myalgic Encephalomyelitis (Encephalopathy); Diagnosis and Management, NICE 2007). However, by understanding the mechanisms that might lead to symptoms in PoTS, exacerbations can be avoided in order to help find a stable base line from which to manage and improve.

We consider fatigue management as being a package of advice that we provide for PoTS patients, it is unlikely that one thing alone will make the difference people want, it is most likely that approaching management of fatigue from multiple perspectives will have the best result.

It is our group’s experience that once PoTS physiology improves, people with CFS/ME are then able to exercise, suggesting that it is the orthostatic intolerance keeping PoTS patients less active rather than an unwillingness to exercise in the first place.

Does the microbiome & virome contribute to ME/CFS?

Posted on 03/12/2018 by wames

Review abstract:

Does the microbiome and virome contribute to myalgic encephalomyelitis/chronic fatigue syndrome? by Fiona Newberry, Shen-Yuan Hsieh, Tom Wileman, Simon R. Carding in Clinical Science Vol 135, #5, pp 523-542 [Published online March 9, 2018]

Myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) (ME/CFS) is a disabling and debilitating disease of unknown aetiology. It is a heterogeneous disease characterized by various inflammatory, immune, viral, neurological and endocrine symptoms.

Several microbiome studies have described alterations in the bacterial component of the microbiome (dysbiosis) consistent with a possible role in disease development.  However, in focusing on the bacterial components of the microbiome, these studies have neglected the viral constituent known as the virome.

Viruses, particularly those infecting bacteria (bacteriophages), have the potential to alter the function and structure of the microbiome via gene transfer and host lysis. Viral-induced microbiome changes can directly and indirectly influence host health and disease. The contribution of viruses towards disease pathogenesis is therefore an important area for research in ME/CFS. Recent advancements in sequencing technology and bioinformatics now allow more comprehensive and inclusive investigations of human microbiomes.

However, as the number of microbiome studies increases, the need for greater consistency in study design and analysis also increases. Comparisons between different ME/CFS microbiome studies are difficult because of differences in patient selection and diagnosis criteria, sample processing, genome sequencing and downstream bioinformatics analysis. It is therefore important that microbiome studies adopt robust, reproducible and consistent study design to enable more reliable and valid comparisons and conclusions to be made between studies.

This article provides a comprehensive review of the current evidence supporting microbiome alterations in ME/CFS patients. Additionally, the pitfalls and challenges associated with microbiome studies are discussed.

Association of CFS with premature telomere attrition (& accelerated ageing)

Posted on 03/09/2018 by wames

Research abstract:

Association of chronic fatigue syndrome with premature telomere attrition, by Mangalathu S. Rajeevan, Janna Murray, Lisa Oakley, Jin-Mann S. Lin, Elizabeth R. Unger in Journal of Translational Medicine Vol 16, #1, p 44 [Published: 27 February 2018]

Background:

Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), is a severely debilitating condition of unknown etiology. The symptoms and risk factors of ME/CFS share features of accelerated aging implicated in several diseases. Using telomere length as a marker, this study was performed to test the hypothesis that ME/CFS is associated with accelerated aging.

Methods:

Participant (n=639) data came from the follow-up time point of the Georgia CFS surveillance study. Using the 1994 CFS Research Case Definition with questionnaire-based subscale thresholds for fatigue, function, and symptoms, participants were classified into four illness groups: CFS if all criteria were met (n=64), CFS-X if CFS with exclusionary conditions (n=77), ISF (insufficient symptoms/fatigue) if only some criteria were met regardless of exclusionary conditions (n=302), and NF (non-fatigued) if no criteria and no exclusionary conditions (n=196).

Relative telomere length (T/S ratio) was measured using DNA from whole blood and real-time PCR. General linear models were used to estimate the association of illness groups or T/S ratio with demographics, biological measures and covariates with significance set at p<0.05.

Results:

The mean T/S ratio differed significantly by illness group (p=0.0017); the T/S ratios in CFS (0.90 p/m 0.03) and ISF (0.94 p/m 0.02) were each significantly lower than in NF (1.06 p/m 0.04). Differences in T/S ratio by illness groups remained significant after adjustment for covariates of age, sex, body mass index, waist-hip ratio, post-exertional malaise and education attainment.

Telomere length was shorter by 635, 254 and 424 base pairs in CFS, CFS-X and ISF, respectively, compared to NF. This shorter telomere length translates to roughly 10.1-20.5, 4.0-8.2 and 6.6-13.7 years of additional aging in CFS, CFS-X and ISF compared to NF respectively. Further, stratified analyses based on age and sex demonstrated that the association of ME/CFS with short telomeres is largely moderated by female subjects<45 years old.

Conclusions:

This study found a significant association of ME/CFS with premature telomere attrition that is largely moderated by female subjects<45 years old. Our results indicate that ME/CFS could be included in the list of conditions associated with accelerated aging. Further work is needed to evaluate the functional significance of accelerated aging in ME/CFS.
