CFS/ME in children aged 5 to 11 years: a qualitative study

Chronic fatigue syndrome/myalgic encephalomyelitis in children aged 5 to 11 years: a qualitative study, by Amberly Brigden, Alison Shaw, Emma Anderson, Esther Crawley in Clinical Child Psychology and Psychiatry Oct 2020 [doi:10.1177/1359104520964528]

 

Research abstract:

Treatments for paediatric chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) have not been designed or evaluated for younger children (5–11-years). The development of a complex intervention for this population requires an in-depth understanding of the perspectives and psychosocial context of children and families.

Children with CFS/ME (5–11-years) and their families were recruited from a specialist CFS/ME service, and interviewed using semi-structured topic guides. Data were analysed thematically. Twenty-two participants were interviewed; eight parents, two children (aged nine and ten) and six parent-child dyads (aged 5–11-years).

Theme 1: CFS/ME in younger children is complex and disabling.

Theme 2: Children aged eight and over (in comparison to those under eight) were more able to describe their illness, engage in clinical consultation, understand diagnosis and self-manage.

Theme 3: Parents of children under eight took full responsibility for their child’s treatment. As children got older, this increasingly became a joint effort between the parent and child.

Parents felt unsupported in their caring role. Clinicians should consider different treatment approaches for children under eight, focusing on: parent-only clinical sessions, training parents to deliver treatment, and increasing support for parents. Children over eight may benefit from tools to help them understand diagnosis, treatment and aids for self-management.

The lonely, isolating & alienating implications of ME/CFS

The lonely, isolating, and alienating implications of Myalgic Encephalomyelitis/ Chronic Fatigue Syndrome by Samir Boulazreg and Ami Rokach in Healthcare 2020, 8(4), 413; [doi.org/10.3390/healthcare8040413]

 

Review abstract:

This article provides a narrative review on myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) through a psychosocial lens and examines how this impairment affects its sufferers during adolescence and adulthood, as well as how it impacts family caregivers and healthcare professionals’ mental health.

Since there has been a lack of investigation in the literature, the primary psychosocial stressor that this review focuses on is loneliness. As such, and in an attempt to help establish a theoretical framework regarding how loneliness may impact ME/CFS, loneliness is comprehensively reviewed, and its relation to chronic illness is described.

We conclude by discussing a variety of coping strategies that may be employed by ME/CFS individuals to address their loneliness. Future directions and ways with which the literature may investigate loneliness and ME/CFS are discussed.

4.1. Summary

To reiterate, chronic illnesses that affect the central nervous system such as ME/CFS does produce psychosocial impairment in 40% of individuals [37]. Though this impairment varies from individual to individual, the age at which sufferers deal with the illness dictates broader and commonly reported themes. For example, adolescents plagued with this disorder miss significant amounts of schooling, which impedes social functioning and future career development skills and can lead to a loss of identity, all of which make young ME/CFS individuals question the meaning of life.

Additionally, a family who receives a diagnosis of ME/CFS for one of its members may experience disruptions of the family dynamic including sibling jealousies and rivalries, guilt, and, strained parent-child relationships resulting from parents and children needing to step into differing roles when assisting (e.g., a parent taking on the role of teacher when homeschooling or a child taking on the role of a parental figure when advising recommendations on what not to do). ME/CFS suffers who are single with no guardians and no dependents also have their own shares of concerns that they must deal with. This includes rumination and stress related to the financial impact of the disorder (e.g., the loss of work and the cost of treatment), fear about being unable to live a normal life and start a family, and decreased autonomy and an increase in reliance on a caregiver. Furthermore, the stigmatization of this illness results in dismissiveness and skepticism from peers, from authority figures (e.g., teachers and employers), and sometimes even from family members.

Concerning loneliness, the main focus of this article, we have provided a brief explanation of what loneliness is, how it may result in distress, unhealthy coping behaviors, and how it relates to chronic illness. In doing so, we have highlighted Leventhal et al.’s [78] study, which showed how one’s conceptualization of illness—e.g., the labeling of the illness and the perception of it, control over how one feels about it, expected consequences, and level of hopefulness—can greatly aid or vastly worsen one’s experience with their illness.

Several coping strategies that caregivers and sufferers of ME/CFS may benefit from were also mentioned, including empathetic behaviors, the attempt to stay in touch with the outside world, peer counseling, support groups, solitude, and the cognitive-behavior approach to how to think about the illness. Additionally, we emphasized the important role healthcare professionals can have with their patients and spoke about the power of spirituality and religiousness as a buffer to ME/CFS-induced loneliness.

4.2. Future Directions
As we previously mentioned at the beginning of this article, there is a lack of investigation surrounding loneliness and how it affects individuals with ME/CFS. As such, we would like to raise some questions that would be of interest and offer insights into conducting research studies with this population.

Questions that glaringly present themselves are: can adequately managed and prolonged exposure to social support networks mitigate symptoms of pain in ME/CFS patients? Additionally, would being in a support group amongst other ME/CFS individuals offer the same buffers to loneliness non-ME/CFS groups? Might these effects be observable via online support groups (e.g., Zoom, Skype, etc.) and would they produce similar outcomes as in-person groups?

The length of illness and how it relates to loneliness are also of interest. For example, since ME/CFS symptoms are present for a minimum of six months and up to, in some cases, more than two years [21], a longitudinal study that tracks loneliness and how one perceives their diagnosis of ME/CFS (including pain, irritability, feelings of control) would be of great interest and could afford insight on whether or not lesser amounts of loneliness translate to a shorter length of pronounced distress faced by the illness.

A specific look at personality traits, such as extraversion and introversion, and questionnaires related to perceptions of joy derived from outings, past job experiences/hobby enjoyment (e.g., Quality of Life Enjoyment and Satisfaction Questionnaire [125], The Minnesota Satisfaction Questionnaire [126], etc.) should also be noted and looked at for further perspectives on illness perception. For example, Davey et al. [122] found that individuals who ranked higher on openness to experience were more accepting of their own inner experiences dealing with chronic illness, resulting in significantly lower pain perception.

Additionally, while difficult, it would be fruitful to sample a comprehensive sample that includes many different cultures and/or backgrounds. Since different cultures are affected and tend to view loneliness differently [127,128,129], it would be interesting to observe if and how these cultural differences fare with respect to coping with ME/CFS. Answers to these questions would undoubtedly result in better treatment protocols and healthcare expectations.

5. Conclusions
Considering that loneliness, its accompanying stigma, and illness conceptualization have a devastating impact in exacerbating chronic illness, we deem the current lack of investigation between loneliness and ME/CFS a major omission in the ME/CFS literature. In closing, we wish to end this article on a quote from Williams-Wilson [10], a researcher who suffers from ME/CFS herself and who investigated the qualitative experiences of adolescents with ME/CFS; drawing from one of the emergent themes of her study, and her personal experiences, she remarked, “finding other people in the same situation as you, with the same struggles and daily trials makes one feel less alone and different from the rest of the world; it provides a sense of affinity and justification and helps alleviate feelings of isolation and loneliness.” (p. 317).

It is thus a healthcare imperative that we take the necessary steps to study and demystify the illness’ alienating and isolating aspects so that those suffering with ME/CFS can feel empowered and compassion from the medical community when dealing with the disorder. Future research may explore the assistance that others, family members, friends, and the community at large can offer those who are struggling with ME/CFS loneliness-related stress and emotional pain.

The case of CFS-ME

The case of Chronic Fatigue Syndrome-Myalgic Encephalomyelitis, by Leonard A Jason, Joseph Cotler, Shaun Bhatia, Madison Sunnquist, Chapter 17: Chronic Illness, pp 228-241 in Handbook of Research Methods in Health Psychology Nov 2020

Prof Leonard Jason’s team have contributed a chapter to a book on research methods in health psychology. They discuss the history & terminology controversy in ME & CFS

 

Chapter overview:

Chronic fatigue syndrome (CFS) and myalgic encephalomyelitis (ME) affect approximately 1 million Americans (Jason, Richman, Rademaker, Jordan, Plioplys, Taylor, et al., 199%); while some individuals believe that CFS and ME refer to the same illness, others characterize ME as a more severe, neurological disorder that is discrete from CFS (Twisk, 2013).

This controversy will be reviewed in detail. The widespread, debilitating symptoms of the illnesses include but are not limited to feeling sick after activity (known as post-exertional malaise), memory and concentration problems, and unrefreshing sleep (IOM, 2015).

Some researchers suggest that ME and CFS were first conceptualized under the diagnostic label ‘neurasthenia,’ defined as a neurological disease characterized by muscle weakness or fatigue. Notably, neurasthenia was one of the most frequently diagnosed illnesses in the late nineteenth century. However, use of this term had substantially decreased by the mid-twentieth century (Wessely, 1994)

Throughout the twentieth century, several outbreaks of idiopathic, fatigue-related illneses occurred, including ‘atypical poliomyelitis’ at Los Angeles County Hospital in 1934 (Meals, Hauser, & Bowe 1938), ‘encephalomyelits’ at the Royal Free Hospital in London in 1955 (Crowley, Nelon, & Stovi 1957), and ‘chronic mononucleosis-like syndrome’ in Lake Tahoe, Nevada, in 1984 (Barnes, 1986). After the Lake Tahoe outbreak, national attention began to focus on this illness (Wessely, 1994), and in 1988, it was named chronic fatigue syndrome by the Centers for Disease Control and Prevention (CDC; Holmes, Kaplan, Gantz, Komaroff, Schonberger, Straus, ct al, 1988). For over two decades, the ease definition that the CDC developed (Fukuda, Straus, Hickic, Sharpe, Dobbins, & Komaroff, 1994) has been prominently used in research and clinical practice; however, the Institute of Medicine (10M) recently developed an updated clinical case definition (IOM, 2015).

The annual direct and indirect costs of ME and CFS in the United States are estimated to be between $19 and $24 billion (Jason, Benton, Johnson, & Valentine, 2008). Individuals with ME and CES have an increased risk of cardiovascular-related mortality and a lower mean age of death by suicide and cancer in comparison to the general US population (McManimen, Devendorf, Brow Moore, Moore, & son, 2016). In addition, arthritis, high blood pressure, fibromyalgia, and multiple chemical sensitivities are commonly comorbid (Jason, Porter, Hunnell, Brown, Rademaker, & Richman, 2011).

Although no virus has been identified as the cause of ME and CFS, the immune system may be overactive (Fischer, William, Strauss, Unger, Jason, Marshall, etc, 2014), and there is and fibromyalgia using regression tree analysis and artificial neural network analysis, composed of computer-based models used to evaluate complex correlations. The patients were randomly divided into two groups. One group served to derive classification criteria sets by sophisticated procedures, including artificial neural networks in parallel. These criteria were then validated with the second group.

Symptoms that best differentiated patients with ME and CES from the other patients were acute onset of fatigue and sore throat.

Additionally, a recent study highlighted that the duration of post-exertional malaise symptoms can distinguish ME and CFS from other chronic illnesses (Cotler, Holtzman, Dudun, & Jason, 2018). The lesson that is apparent from this section is that it is essential for a consensus on a case definition among investigators for establishing a solid empiric foundation in any illness or disease.

EUROMENE epidemiological research – Dr Derek Pheby invites you to take part

Dr Derek Pheby invites you to take part in EUROMENE research

19th October 2020

Dear fellow members of the ME community,

I wonder if I could, please, request your assistance. I am working with European colleagues in the EUROMENE collaboration, and we have been very successful in stimulating research into ME/CFS throughout Europe.

Researchers in Latvia and Italy have conducted fairly small-scale epidemiological studies, with the intention of producing an international comparison, and would like to be able to compare their results with data from the UK, where most of the epidemiological research into ME/CFS in Europe has been undertaken.

Epidemiology is the study of how often diseases occur in different groups of people and why.                             BMJ

I am very keen to encourage this development, as it is only through epidemiological research that we will be able to quantify the scale of the illness in Europe, which in turn will get added weight to our lobbying for increased resources both for research and for clinical and other services.

I have therefore developed a short survey instrument to enable collection of data which will facilitate the comparison my Latvian and Italian colleagues wish to make. This is necessarily limited in scope, because I am only asking the questions which have been asked in the surveys already carried out in Latvia and Italy. It’s therefore quite short, and it should be possible to complete it in under ten minutes.

If you:

  • are a UK resident,
  • have a medically confirmed diagnosis of ME/CFS, and
  • would like to participate

Take part in the survey https://www.smartsurvey.co.uk/s/GX4HMU/

Please feel free to send this link to anyone else who might be interested and may want to participate.

I would be grateful for responses by the end of October, please.

The survey is of course completely anonymous, but, if you would like to receive a report of this study in due course and leave your email address at the end of the survey, or alternatively email me at derekpheby@btinternet.com I will make sure that this is sent to you.

Yours faithfully,

Professor Derek Pheby, 

Chairman, Socioeconomics Working Group, EUROMENE

Cytokine profiling of extracellular vesicles isolated from plasma in ME/CFS

Cytokine profiling of extracellular vesicles isolated from plasma in myalgic encephalomyelitis/ chronic fatigue syndrome: a pilot study, by Ludovic Giloteaux, Adam O’Neal, Jesús Castro-Marrero, Susan M Levine, Maureen R Hanson in J Transl Med. 2020 Oct 12;18(1):387 [doi: 10.1186/s12967-020-02560-0]

 

Research abstract:

Background:

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating disease of unknown etiology lasting for a minimum of 6 months but usually for many years, with features including fatigue, cognitive impairment, myalgias, post-exertional malaise, and immune system dysfunction. Dysregulation of cytokine signaling could give rise to many of these symptoms. Cytokines are present in both plasma and extracellular vesicles, but little investigation of EVs in ME/CFS has been reported. Therefore, we aimed to characterize the content of extracellular vesicles (EVs) isolated from plasma (including circulating cytokine/chemokine profiling) from individuals with ME/CFS and healthy controls.

Methods:

We included 35 ME/CFS patients and 35 controls matched for age, sex and BMI. EVs were enriched from plasma by using a polymer-based precipitation method and characterized by Nanoparticle Tracking Analysis (NTA), Transmission Electron Microscopy (TEM) and immunoblotting. A 45-plex immunoassay was used to determine cytokine levels in both plasma and isolated EVs from a subset of 19 patients and controls. Linear regression, principal component analysis and inter-cytokine correlations were analyzed.

Results:

ME/CFS individuals had significantly higher levels of EVs that ranged from 30 to 130 nm in size as compared to controls, but the mean size for total extracellular vesicles did not differ between groups. The enrichment of typical EV markers CD63, CD81, TSG101 and HSP70 was confirmed by Western blot analysis and the morphology assessed by TEM showed a homogeneous population of vesicles in both groups. Comparison of cytokine concentrations in plasma and isolated EVs of cases and controls yielded no significant differences.

Cytokine-cytokine correlations in plasma revealed a significant higher number of interactions in ME/CFS cases along with 13 inverse correlations that were mainly driven by the Interferon gamma-induced protein 10 (IP-10), whereas in the plasma of controls, no inverse relationships were found across any of the cytokines. Network analysis in EVs from controls showed 2.5 times more significant inter-cytokine interactions than in the ME/CFS group, and both groups presented a unique negative association.

Conclusions:

Elevated levels of 30-130 nm EVs were found in plasma from ME/CFS patients and inter-cytokine correlations revealed unusual regulatory relationships among cytokines in the ME/CFS group that were different from the control group in both plasma and EVs. These disturbances in cytokine networks are further evidence of immune dysregulation in ME/CFS.

Reductions in cerebral blood flow can be provoked by sitting in severe ME/CFS patients

Reductions in cerebral blood flow can be provoked by sitting in severe Myalgic Encephalomyelitis/Chronic Fatigue Syndrome patients, by C (Linda) MC van Campen, Peter C Rowe and Frans C Visser in Healthcare 2020, 8(4), 394 [doi.org/10.3390/healthcare8040394]

 

Research abstract:

Introduction:

In a large study with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) patients, we showed that 86% had symptoms of orthostatic intolerance in daily life and that 90% had an abnormal reduction in cerebral blood flow (CBF) during a standard tilt test.

A standard head-up tilt test might not be tolerated by the most severely affected bed-ridden ME/CFS patients. Sitting upright is a milder orthostatic stress. The present study examined whether a sitting test, measuring cerebral blood flow by extracranial Doppler, would be sufficient to provoke abnormal reductions in cerebral blood flow in severe ME/CFS patients.

Methods and results:

100 severe ME/CFS patients were studied, (88 females) and were compared with 15 healthy controls (HC) (13 females). CBF was measured first while seated for at least one hour, followed by a CBF measurement in the supine position. Fibromyalgia was present in 37 patients. Demographic data as well as supine heart rate and blood pressures were not different between ME/CFS patients and HC.

Heart rate and blood pressure did not change significantly between supine and sitting both in patients and HC. Supine CBF was not different between patients and HC. In contrast, absolute CBF during sitting was lower in patients compared to HC: 474 (96) mL/min in
patients and 627 (89) mL/min in HC; p < 0.0001. As a result, percent CBF reduction while seated was −24.5 (9.4)% in severe ME/CFS patients and −0.4 (1.2)% in HC (p < 0.0001).

In the ten patients who had no orthostatic intolerance complaints in daily life, the CBF reduction was −2.7 (2.1)%, which was not significantly different from HC (p =0.58). The remaining 90 patients with orthostatic intolerance complaints had a −26.9 (6.2)% CBF reduction.

No difference in CBF parameters was found in patients with and without fibromyalgia. Patients with a previous diagnosis of postural orthostatic tachycardia syndrome (POTS) had a significantly larger CBF reduction compared with those without POTS: 28.8 (7.2)% vs. 22.3 (9.7)% (p = 0.0008).

Conclusions:

A sitting test in severe ME/CFS patients was sufficient to provoke a clinically and statistically significant mean CBF decline of 24.5%. Patients with a previous diagnosis of POTS had a larger CBF reduction while seated, compared to patients without POTS. The magnitude of these CBF reductions is similar to the results in less severely affected ME/CFS patients during head-up tilt, suggesting that a sitting test is adequate for the diagnosis of orthostatic intolerance in severely affected patients.

Short fatigue questionnaire: screening for severe fatigue

Short fatigue questionnaire: screening for severe fatigue, by Adriaan Penson, Sylvia van Deuren, Margreet Worm-Smeitink, Ewald Bronkhorst, Frank HJ van den Hoogen, Baziel GM van Engelen, Marlies Peters, Gijs Bleijenberg, Jan H Vercoulen, Nicole Blijlevens, Eline van Dulmen-den Broeder, Jacqueline Loonen, Hans Knoop in Journal of Psychosomatic Research Vol 137, Oct 2020, 110229 [doi.org/10.1016/j.jpsychores.2020.110229]

 

Highlights:

  • To optimally screen for severe fatigue, a short version of the Checklist Individual Strength was proposed: the Short Fatigue Questionnaire (SFQ)
  • Psychometric properties of the SFQ are satisfying
  • A cut-off score of 18 is recommended to identify severe fatigue
  • Norm values are presented and can be used as reference values
  • The SFQ is an excellent instrument to screen for severe fatigue

 

Abstract:

Objective:

To determine psychometric properties, a cut-off score for severe fatigue and normative data for the 4-item Short Fatigue Questionnaire (SFQ) derived from the multi-dimensional fatigue questionnaire Checklist Individual Strength (CIS).

The Shortened Fatigue Questionnaire (SFQ) [10] consists of four items (‘I feel tired’, ‘I tire easily‘, ‘I feel fit’ and ‘I feel physically exhausted’; see appendix B). Each item is scored on a 7-point Likert Scale, ranging from 1 ‘yes, that is true’ to 7 ‘no, that is not true’. Scores of items 1, 2 and 4 are reversed and then all item scores are added up which results in a total score varying from 4 to 28. Higher scores reflect a higher level of fatigue.

Methods:

Data of previous studies investigating the prevalence of fatigue in ten chronic conditions (n = 2985) and the general population (n = 2288) was used to determine the internal consistency (Cronbach’s alpha) of the SFQ, its relation with other fatigue measures (EORTC QLQ-30 fatigue subscale and digital fatigue diary), a cut-off score for severe fatigue (ROC analysis) and to examine whether the four SFQ items truly measure the same construct. Norms were calculated for ten patient groups and the Dutch general population.

Results:

Cronbach’s alpha of the SFQ were excellent in almost all groups.

Psychometric characteristics of the SFQ were shown to be adequate. Cronbach’s alpha was high for almost all study populations, except for the CFS population. A plausible explanation for the latter could be the fact that the CFS group scored extremely high on the SFQ decreasing the variance of the item- and total scores. The reason why this group scored this high on the SFQ is explained by the fact that one of the criteria to meet the case definition of CFS is scoring above the cut-off score of 35 on the CIS fatigue severity subscale. As the SFQ is derived from the CIS, this will lead to a restricted range of scores. This suggests that the internal consistency itself was not necessarily lower in the CFS population. The relation between the SFQ and other fatigue measures showed the construct validity to be satisfying.

Pearson’s correlations between the SFQ and the EORTC-QLQ-C30 fatigue subscale and a fatigue diary were respectively 0.76 and 0.68. ROC analysis showed an area under the curve of 0.982 (95% CI: 0.979–0.985) and cut-off score of 18 was suggested which showed a good sensitivity (0.984) and specificity (0.826) as well as excellent values for the positive and negative prediction values within all groups using the CIS as golden standard. Factor analysis showed a one factor solution (Eigenvalue: 3.095) with factor loadings of all items on the factor being greater than 0.87.

Conclusion:

The SFQ is an easy to use, reliable and valid instrument to screen for severe fatigue in clinical routine and research.
