‘The real me shining through M.E.’: visualizing masculinity & identity threat in men with ME/CFS

‘The real me shining through M.E.’: Visualizing masculinity and identity threat in men with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome using photovoice and IPA, by Lucina Wilde, Kerry Quincey, I.R Williamson in Psychology of Men & Masculinity, April 30, 2019

 

Research abstract:

Phenomenological research in the context of Myalgic Encephalomyelitis (M.E.) or Chronic Fatigue Syndrome (CFS) has predominantly explored women’s accounts. Due to the paucity of research highlighting men’s experiences of living with M.E./CFS, the aim of this research was to explore their visual and verbal accounts to gain a more in-depth understanding of how they make sense of their diagnosis and dual identity as a man with a stigmatized and often misunderstood chronic illness.

Working within a critical health psychology framework the study utilised a phenomenological approach and an adapted version of Photovoice to gather and interrogate self-authored photographs and interview accounts from ten men living with M.E./CFS.

An Interpretative Phenomenological Analysis of the integrated visual and verbal data led to the development of three themes:

  • ‘Loss of Masculine Identity as Man with M.E./CFS’,
  • ‘Marginalization attached to M.E./CFS and Masculinity’ and
  • ‘Coping with Dual Identity by Adjustments, Assimilation and Acceptance’.

The findings show how men with CFS cope with identity threat across personal, social, and cultural contexts, whilst making adaptations in their perceptions and performances of masculinity. We argue that participant-authored photographs could be used by researchers, activists and practitioners to facilitate increased understanding of and support for men with M.E./CFS.

CFS/ME & FM: the foundation of a relationship

Chronic fatigue syndrome (CFS)/Myalgic Encephalomyelitis (ME) and Fibromyalgia (FM): the foundation of a relationship, by Pamela G Mckay, Colin R Martin, Helen Walker, Mick Fleming in British Journal of Pain Oct 2019 [doi.org/10.1177/2049463719875164]

Research abstract:

Introduction:
Chronic fatigue syndrome (CFS)/Myalgic Encephalomyelitis (ME) and fibromyalgia (FM) are both debilitating syndromes with complex polysymptomatology. Early research infers that a relationship may exist even though the diagnosis provided may influence the management trajectory. In the absence of a diagnostic test and treatment, this study aims to confirm the symptoms and their severity, which may infer a relationship and influence future research.

Method:
A quasi-experimental design was utilised, using Internet-based self-assessment questionnaires focusing on nine symptom areas: criteria, pain, sleep, fatigue, anxiety and depression, health-related quality of life, self-esteem and locus of control.

The questionnaires used for data collection are as follows: the American Centre for Disease Control and Prevention Symptom Inventory for CFS/ME (American CDC Symptom Inventory); the American College of Rheumatology (ACR) Criteria for FM; Fibromyalgia Impact Questionnaire (FIQ); McGill Pain Questionnaire (MPQ); Multidimensional Fatigue Inventory (MFI); Pittsburgh Sleep Quality Index (PSQI); Health-Related Quality of Life SF-36 V2 (HRQoL SF-36 V2); Hospital Anxiety and Depression Scale (HADS); Multidimensional Health Locus of Control (MHLOC) and the Rosenberg Self-Esteem Scale (RSES).

Setting and participants:
Participants were recruited from two distinct community groups, namely CFS/ME (n = 101) and FM (n = 107). Participants were male and female aged 17 (CFS/ME mean age 45.5 years; FM mean age 47.2 years).

Results:
All participants in the CFS/ME and FM groups satisfied the requirements of their individual criteria. Results confirmed that both groups experienced the debilitating symptoms measured, with the exception of anxiety and depression, impacting on their quality of life. Results suggest a relationship between CFS/ME and FM, indicating the requirement for future research.

Low-dose naltrexone in the treatment of ME/CFS

Low-dose naltrexone in the treatment of myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS), by Olli Polo, Pia Pesonen, Essi Tuominen in Fatigue: Biomedicine, Health & Behavior Nov 19, 2019 [doi/full/10.1080/21641846.2019.1692770]

 

Research abstract:

Background:
Myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) is a common medical condition that limits physical and cognitive functions, with no known effective medical treatment.

Methods:
We report on the safety and effectiveness data accumulated in clinical practice when treating ME/CFS with low-dose naltrexone (LDN, 3.0-4.5 mg/day). The medical records from 218 patients who received ar diagnosis of ME/CFS and LDN treatment during 2010-2014 were retrospectively analyzed.

Results:
Outcome data were available in 92.2% of patients with an average follow-up time of 1.7 years. A positive treatment response to LDN was reported by 73.9% of the patients. Most patients experienced improved vigilance/alertness and improved physical and cognitive performance. Some patients reported less pain and fever, while 18.3% of patients did not report any treatment response to LDN. Mild adverse effects (insomnia, nausea) were common at the beginning of the treatment. Neither severe adverse effects nor long-term adverse symptoms were reported.

Conclusions:
The high frequency of treatment response and good safety profile observed in this retrospective open label study could prompt prospective controlled studies to confirm the feasibility of LDN in alleviating ME/CFS symptoms.

Relationship satisfaction, communication self-efficacy & CFS

Relationship satisfaction, communication self-efficacy, and chronic fatigue syndrome-related fatigue, by Sara F Milrad, Daniel L Hall, Devika R Jutagir, Emily G Lattie, Sara J Czaja, Dolores M Perdomo, Gail Ironson, Brian D Doss, Armando Mendez, Mary Ann Fletcher, Nancy Klimas, Michael H Antonia in Social Science & Medicine Vol 237, Sep 2019 [https://doi.org/10.1016/j.socscimed.2019.112392]

 

Research highlights:

  • Relationship satisfaction and depression can impact CFS-related fatigue.
  • Patient symptom disclosure satisfaction (PSDS) is a hypothesized intermediate.
  • Depression and PSDS were examined as intermediary variables of this relationship.
  • Relationship satisfaction was related to fatigue severity via depression and PSDS.
  • This underscores the importance of considering these factors in the context of CFS.

Research abstract:

Rationale
Relationship dissatisfaction has been linked with worse health outcomes in many patient populations, though the mechanism(s) underlying this effect are unclear. Among patients with chronic fatigue syndrome (CFS) and their partners, there is evidence for a bi-directional association between poorer relationship satisfaction and the severity of CFS-related fatigue.

Objective
Here, we hypothesized that relationship dissatisfaction negatively impacts fatigue severity through greater depression and less patient satisfaction about communication about symptoms to partners.

Method
Baseline data were drawn from diagnosed CFS patients (N = 150) participating in a trial testing the efficacy of a stress management intervention. Data derived from fatigue severity (Fatigue Symptom Index, FSI), depression (Center for Epidemiologic Survey-Depression, CES-D), relationship quality (Dyadic Adjustment Scale, DAS) and communication satisfaction (Patient Symptom Disclosure Satisfaction, PSDS) questionnaires were used for bootstrapped indirect effect analyses using parallel mediation structural equation modeling in Mplus (v8). Age and BMI were entered as covariates.

Results
Greater relationship satisfaction predicted greater communication satisfaction (p < 0.01) and lower CES-D scores (p < 0.01), which in turn were each significantly related to greater fatigue severity (p < 0.05). Tests of the indirect paths indicated that relationship satisfaction had a significant effect on fatigue severity through both constructs, but primarily via depression. There was no direct association between relationship satisfaction and fatigue severity after the intermediate variables (depression, communication satisfaction) were included in the model.

Conclusion
Results highlight the importance of considering depression and communication-related factors when examining the effects of relationship satisfaction on CFS symptoms such as fatigue. Further mechanism-based, longitudinal research might identify relationship-related mediating variables that can be targeted therapeutically.

Assessing CFS: self-reported physical functioning & correlations with physical testing

Assessing chronic fatigue syndrome: Self-reported physical functioning and correlations with physical testing, by  Jan Eyskens, Jela Illegems, Luc De Nil, Jo Nijs, Jarl K Kampen, Greta Moorkens in Journal of Bodywork and Movement Therapies Vol 23, No. 3, Jul 2019, pp 598-603 [https://doi.org/10.1016/j.jbmt.2019.03.006]

 

Abstract of Cross-Sectional Study:

The pathophysiology of chronic fatigue syndrome (CFS) remains unclear; no biomarkers have thus far been identified or physical tests designed to underpin its diagnosis. Assessment mainly uses Fukuda’s criteria and is based on the exclusion of symptoms related to other diseases/syndromes, subjective self-reporting, and outcomes of self-report questionnaires.

In order to improve the baseline assessment and progress evaluation of individuals suspected of CFS and using an association-oriented research strategy and a cross-correlational design, this study investigates possible associations between the performance on two physical tests, i.e. ‘Timed Loaded Standing’ (TLS), assessing trunk-arm endurance, and the ‘Stops Walking with Eyes Closed while performing a secondary Cognitive Task’ (SWECCT), measuring impaired automaticity of gait, and the results of two self-report questionnaires, the Checklist Individual Strength (CIS, total score and fatigue subscale score) and the physical functioning and vitality subscales of the Short Form Health Survey (SF-36) to gauge the participants’ subjective feelings of fatigue and beliefs regarding their abilities to perform daily-life activities.

Comparisons of the outcomes obtained in 27 female patients with a confirmed diagnosis of CFS revealed that trunk-arm endurance as measured with the TLS correlated with the SF-36 physical functioning subscale only (raw p value: 0.004).

None of the other correlations were statistically significant. It is concluded that the TLS may have potential as an objective assessment tool to support the diagnosis and monitoring of treatment effects in CFS.

ME/CFS as a hyper-regulated immune system driven by an interplay between regulatory T cells & chronic human herpesvirus infections

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome as a hyper-regulated immune system driven by an interplay between regulatory T cells and chronic human herpesvirus infections, by Nuno Sepúlveda,  Jorge Carneiro,  Eliana M Lacerda and  Luis C Nacul in Front. Immunol. 21 Nov 2019 [https://doi.org/10.3389/fimmu.2019.02684]

 

Hypothesis & theory article abstract:

Conceptual scheme of the cross-regulation model

Autoimmunity and chronic viral infections are recurrent clinical observations in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), a complex disease with an unknown cause.

Given these observations, the regulatory CD4+ T cells (Tregs) show promise to be good candidates for the underlying pathology due to their known capacity to suppress the immune responses not only to body components but also against infections. Here we discussed the overlooked role of these cells in the chronicity of Human Herpes Virus 6 (HHV6), Herpes Simplex 1 (HSV1) and Epstein-Barr virus (EBV), as often reported as triggers of ME/CFS.

Using simulations of the Cross-regulation model for the dynamics of Tregs, we illustrated that mild infections might lead to a chronically activated immune responses under control of Tregs if the responding clone has a high autoimmune potential. Such infections promote persistent inflammation and possibly fatigue.

We then hypothesized that ME/CFS is a condition characterized by a predominance of this type of infections under control of Tregs. In contrast, healthy individuals are hypothesized to trigger immune responses of a virus-specific clone with a low autoimmune potential.

According to this hypothesis, simple model simulations of the CD4+ T-cell repertoire could reproduce the increased density and percentages of Tregs observed in patients suffering from the disease when compared to healthy controls. A deeper analysis of Tregs in the pathogenesis of ME/CFS will help to assess the validity of this hypothesis.

A systematic review of natural killer cells profile & cytotoxic function in ME/CFS

A systematic review of natural killer cells profile and cytotoxic function in myalgic encephalomyelitis/chronic fatigue syndrome, by Natalie Eaton-Fitch, Stanley du Preez, Hélène Cabanas, Donald Staines & Sonya Marshall-Gradisnik in Systematic Reviews vol 8, no: 279 (2019)

 

Review abstract:

Background:
Compromised natural killer (NK) cell cytotoxic function is a well-documented and consistent feature of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Other outcomes evaluated in NK cells of ME/CFS patients, however, remain equivocal. The aim of this study was to conduct a systematic review of the literature regarding NK cell phenotype, receptor expression, cytokine production and cytotoxicity in ME/CFS patients and determine the appropriateness as a model for ME/CFS.

Methods:
Medline (EBSCOHost), Scopus, EMBASE and PubMed databases were systematically searched to source relevant papers published between 1994 and March 2018. This review included studies examining NK cells’ features in ME/CFS patients compared with HC following administration of specific inclusion and exclusion criteria. Secondary outcomes included genetic analysis in isolated NK cells or quality of life assessment. Quality assessment was completed using the Downs and Black checklist in addition to The Joanna Briggs Institute checklist.

Results:
Seventeen eligible publications were included in this review. All studies were observational case control studies. Of these, 11 investigated NK cell cytotoxicity, 14 investigated NK cell phenotype and receptor profiles, three examined NK cell cytokine production, six investigated NK cell lytic protein levels and four investigated NK cell degranulation. Impaired NK cell cytotoxicity remained the most consistent immunological report across all publications. Other outcomes investigated differed between studies.

Conclusion:
A consistent finding among all papers included in this review was impaired NK cell cytotoxicity, suggesting that it is a reliable and appropriate cellular model for continued research in ME/CFS patients. Aberrations in NK cell lytic protein levels were also reported. Although additional research is recommended, current research provides a foundation for subsequent investigations. It is possible that NK cell abnormalities can be used to characterise a subset of ME/CFS due to the heterogeneity of both the illness itself and findings between studies investigating specific features of NK function.

The longitudinal effects of seated isometric yoga on blood biomarkers, autonomic functions, & psychological parameters of patients with CFS

The longitudinal effects of seated isometric yoga on blood biomarkers, autonomic functions, and psychological parameters of patients with chronic fatigue syndrome: a pilot study, by Takakazu Oka, Tokusei Tanahashi, Battuvshin Lkhagvasuren, & Yu Yamada in BioPsychoSocial Medicine vol 13, no: 28 (2019)

 

Research abstract:

Background:
In a previous randomized controlled trial, we found that practicing seated isometric yoga regularly for 2 months improved the fatigue of patients with chronic fatigue syndrome (CFS) who are resistant to conventional therapy. The aim of this pilot study was to investigate the possible mechanisms behind this finding by comparing blood biomarkers, autonomic nervous function, and psychological indices before versus after an intervention period of seated isometric yoga practice.

Methods:
Fifteen patients with CFS who did not show satisfactory improvements after at least 6 months of conventional therapy practiced seated isometric yoga (biweekly 20-min sessions with a yoga instructor and daily practice at home) for 2 months. The longitudinal effects of seated isometric yoga on fatigue, blood biomarkers, autonomic function, and psychological state were investigated by comparing the following parameters before and after the intervention period: Fatigue severity was assessed by the Chalder fatigue scale (FS) score. Levels of the blood biomarkers cortisol, DHEA-S, TNF-α, IL-6, prolactin, carnitine, TGF-β1, BDNF, MHPG, HVA, and α-MSH were measured. The autonomic nervous functions assessed were heart rate (HR) and HR variability. Psychological indices included the 20-item Toronto Alexithymia Scale (TAS-20) and the Hospital Anxiety and Depression Scale (HADS).

Results:
Practicing seated isometric yoga for 2 months resulted in significant reductions in the Chalder FS (P = 0.002) and HADS-depression (P = 0.02) scores. No significant changes were observed in any other parameter evaluated. The change in Chalder FS score was not correlated with the change in HADS-depression score. However, this change was positively correlated with changes in the serum TNF-α levels (P = 0.048), the high frequency component of HR variability (P = 0.042), and TAS-20 scores (P = 0.001).

Conclusions:
Regular practice of seated isometric yoga for 2 months reduced the fatigue and depressive symptom scores of patients with CFS without affecting any other parameters we investigated. This study failed to identify the markers responsible for the longitudinal fatigue-relieving effect of seated isometric yoga. However, considering that the reduced fatigue was associated with decreased serum TNF-α level and TAS-20 scores, fatigue improvement might be related to reduced inflammation and improved alexithymia in these patients.

Developing & pretesting a new patient reported outcome measure for paediatric CFS/ME

Developing and pretesting a new patient reported outcome measure for paediatric Chronic Fatigue Syndrome/Myalgic Encephalopathy (CFS/ME): cognitive interviews with children, by Roxanne M. Parslow, Alison Shaw, Kirstie L Haywood, Esther Crawley in Journal of Patient-Reported Outcomes Vol 3, p 67 [First Online 09 November 2019]

 

Research abstract:

Background:
There is a lack of patient derived, child specific outcome measures to capture what health outcomes are important to children with Chronic Fatigue Syndrome/ Myalgic Encephalopathy (CFS/ME). We developed a new Patient Reported Outcome Measure (PROM) for paediatric CFS/ME through qualitative research with children. This study aimed to pre-test the new measure through cognitive interviews with children with CFS/ME.

Methods:
Cognitive interviews were undertaken in children’s homes or over Skype. The Three-Step Test-Interview (TSTI) method was used to assess the quality of the draft PROM with children with CFS/ME to identify problems with initial content and design and test modifications over subsequent interview rounds. Children were purposively sampled from a single specialist paediatric CFS/ME service in England.

Results:
Twenty-four children and their parents took part. They felt the new measure captured issues relevant to their condition and preferred it to the generic measures they completed in clinical assessment. Changes were made to item content and phrasing, timeframe and response options and tested through three rounds of interviews.

Conclusions:
Cognitive interviews identified problems with the draft PROM, enabling us to make changes and then confirm acceptability in children aged 11-18. Further cognitive interviews are required with children 8-10 years old to examine the acceptability and content validity and provide evidence for age related cut offs of the new PROM to meet FDA standards. This study demonstrates the content validity of the new measure as relevant and acceptable for children with CFS/ME. The next stage is to undertake a psychometric evaluation to support the reduction of items, confirm the structure of the PROM and provide evidence of the data quality, reliability and validity.
