Graded exercise therapy compared to activity management for paediatric chronic fatigue syndrome/myalgic encephalomyelitis: pragmatic randomized controlled trial

Abstract

The MAGENTA pragmatic parallel groups randomized controlled trial compared graded exercise therapy (GET) with activity management (AM) in treating paediatric myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS). Children aged 8-17 years with mild/moderate ME/CFS and presenting to NHS specialist paediatric services were allocated at random to either individualised flexible treatment focussing on physical activity (GET, 123 participants) or on managing cognitive, school and social activity (AM, 118 participants) delivered by NHS therapists.

The primary outcome was the self-reported short-form 36 physical function subscale (SF-36-PFS) after 6 months, with higher scores indicating better functioning. After 6 months, data were available for 201 (83%) participants who received a mean of 3.9 (GET) or 4.6 (AM) treatment sessions. Comparing participants with measured outcomes in their allocated groups, the mean SF-36-PFS score changed from 54.8 (standard deviation 23.7) to 55.7 (23.3) for GET and from 55.5 (23.1) to 57.7 (26.0) for AM giving an adjusted difference in means of -2.02 (95% confidence interval -7.75, 2.70). One hundred thirty-five participants completed the mean SF-36-PFS at 12 months, and whilst further improvement was observed, the difference between the study groups remained consistent with chance.

The two study groups showed similar changes on most of the secondary outcome measures: Chalder Fatigue, Hospital Anxiety and Depression Scale: Depression, proportion of full-time school attended, a visual analogue pain scale, participant-rated change and accelerometer measured physical activity, whether at the 6-month or 12-month assessment.

There was an isolated finding of some evidence of an improvement in anxiety in those allocated to GET, as measured by the Hospital Anxiety and Depression Scale at 6 months, with the 12-month assessment, and the Spence Children’s Anxiety scale being aligned with that finding. There was weak evidence of a greater risk of deterioration with GET (27%) than with AM (17%; p = 0.069).

At conventional UK cost per QALY thresholds, the probability that GET is more cost-effective than AM ranged from 18 to 21%. Whilst completion of the SF-36-PFS, Chalder Fatigue Scale and EQ-5D-Y was good at the 6-month assessment point, it was less satisfactory for other measures, and for all measures at the 12-month assessment.

Conclusion: There was no evidence that GET was more effective or cost-effective than AM in this setting, with very limited improvement in either study group evident by the 6-month or 12-month assessment points.

Therapeutic Potential of Indian Medicinal Herbs and Current Therapeutic Approach used to Mitigate the Symptoms of Chronic Fatigue Syndrome: A Review

Abstract:

Chronic fatigue syndrome (CFS) is a complex condition marked by severe exhaustion that lasts at least 6 months. The global prevalence of CFS ranging between 0.4% and 2.5% is growing. Women are affected by CFS more often than men. It is considered a common condition in developed countries. There is no approved treatment for CFS but symptoms can be managed and controlled persistent exhaustion causes significant impairment in daily routine activities. Lowered ATP synthesis, mitochondrial impairment, decreased oxidative phosphorylation, disruption of the hypothalamic–pituitary–adrenal (HPA) axis, and an imbalance of brain neurotransmitters play a major role in the pathophysiology of CFS.

The purpose of the present study is to figure out the several plants that are used as a source of medication in chronic fatigue syndrome (CFS) and its current therapeutic approach. The Indian medicinal herbs described in this article are very efficacious in the management of chronic fatigue syndrome symptoms due to the presence of phytochemicals.

This review article also covers the current therapeutic approach for chronic fatigue syndrome in a concise form that comprises CBT (Cognitive based therapy), GET (Graded exercise therapy), usage of immunoglobins, psychodynamic counseling, and yoga therapy that includes isometric yoga and yoga nidra are very beneficial in alleviating the symptoms of chronic fatigue syndrome. Antidepressants, immunomodulatory agents, and corticosteroids come under conventional medication for CFS.

This article explores different Indian medicinal herbs, their pharmacological properties, and their potential role and current treatments for reducing the severity of symptoms of chronic fatigue syndrome.

Comparative Survey of People with ME/CFS in Italy, Latvia, and the UK: A Report on Behalf of the Socioeconomics Working Group of the European ME/CFS Research Network (EUROMENE)

Abstract:

Background and Objectives: A comparative survey of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) patients was carried out in three countries, with the aim of identifying appropriate policy measures designed to alleviate the burden of disease both on patients and their families, and also on public institutions. The survey addressed demographic features, the economic impact of the disease on household incomes, patterns of medical and social care, specific therapies, social relationships, and the impact of the illness on quality of life.

Materials and Methods: Parallel surveys were undertaken in Italy, Latvia, and the UK. There were 88 completed responses from Italy, 75 from Latvia, and 448 from the UK. To facilitate comparisons, 95% confidence intervals were calculated in respect of responses to questions from all three countries. To explore to what extent general practitioners (GPs) manage ME/CFS disease, a separate questionnaire for GPs, with questions about the criteria for granting a diagnosis, laboratory examinations, the involvement of specialists, and methods of treatment, was undertaken in Latvia, and there were 91 completed responses from GPs.

Results: The results are presented in respect of sociodemographic information, household income, disease progression and management, perceived effectiveness of treatment, responsibility for medical care, personal care, difficulty explaining the illness, and quality of life. Demographic details were similar in all three countries, and the impact of illness on net household incomes and quality of life. There were significant differences between the three countries in illness progression and management, which may reflect differences in patterns of health care and in societal attitudes. Graded exercise therapy, practiced in the UK, was found to be universally ineffective.

Conclusions: There were similarities between respondents in all three countries in terms of demographic features, the impact of the illness on household incomes and on quality of life, and on difficulties experienced by respondents in discussing their illness with doctors, but also differences in patterns of medical care, availability of social care, and societal attitudes to ME/CFS.

Cost-effectiveness of Interventions for Chronic Fatigue Syndrome or Myalgic Encephalomyelitis: A Systematic Review of Economic Evaluations

Abstract:

Introduction: Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) has profound quality of life and economic consequences for individuals, their family, formal services and wider society. Little is known about which therapeutic interventions are more cost-effective.

Objective: A systematic review was carried out to identify and critically appraise the evidence on the cost-effectiveness of CFS/ME interventions.

Methods: The review protocol was prespecified (PROSPERO: CRD42018118731). Searches were carried out across two databases-MEDLINE (1946-2020) and EMBASE (1974-2020). Additional studies were identified by searching reference lists. Only peer-reviewed journal articles of full economic evaluations examining CFS/ME interventions were included. Trial- and/or model-based economic evaluations were eligible. Data extraction and screening were carried out independently by two reviewers. The methodological quality of the economic evaluation and trial were assessed using the Consensus Health Economic Criteria checklist (CHEC-list) and Risk of Bias-2 (RoB-2) tool, respectively. A narrative synthesis was used to summarise the economic evidence for interventions for adults and children in primary and secondary care settings.

Results: Ten economic evaluations, all based on data derived from randomised controlled trials, met our eligibility criteria. Cognitive behavioural therapy (CBT) was evaluated across five studies, making it the most commonly evaluated intervention. There was evidence from three trials to support CBT as a cost-effective treatment option for adults; however, findings on CBT were not uniform, suggesting that cost-effectiveness may be context-specific. A wide array of other interventions were evaluated in adults, including limited evidence from two trials supporting the cost effectiveness of graded exercise therapy (GET). Just one study assessed intervention options for children. Our review highlighted the importance of informal care costs and productivity losses in the evaluation of CFS/ME interventions.

Conclusions: We identified a limited patchwork of evidence on the cost-effectiveness of interventions for CFS/ME. Evidence supports CBT as a cost-effective treatment option for adults; however, cost-effectiveness may depend on the duration and frequency of sessions. Limited evidence supports the cost effectiveness of GET. Key weaknesses in the literature included small sample sizes and short duration of follow-up. Further research is needed on pharmacological interventions and therapies for children.

Prediction of Discontinuation of Structured Exercise Programme in Chronic Fatigue Syndrome Patients

Abstract:

Purpose: The purpose of this study was to assess differences in the physiological profiles of completers vs. non-completers following a structured exercise programme (SEP) and the ability to predict non-completers, which is currently unknown in this group.

Methods: Sixty-nine patients met the Fukuda criteria. Patients completed baseline measures assessing fatigue, autonomic nervous system (ANS), cognitive, and cardiovascular function. Thirty-four patients completed a home-based SEP consisting of 10-40 min per day at between 30 and 80% actual HR max. Exercise intensity and time was increased gradually across the 16 weeks and baseline measures were repeated following the SEP.

Results: Thirty-five patients discontinued, while 34 completed SEP. For every increase in sympathetic drive for blood pressure control as measured by the taskforce, completion of SEP decreased by a multiple of 0.1. For a 1 millisecond increase in reaction time for the simple reaction time (SRT), the probability for completion of SEP also decreases by a multiple of 0.01. For a one beat HRmax increase, there is a 4% increase in the odds of completing SEP.

Conclusion: The more sympathetic drive in the control of blood vessels, the longer the reaction time on simple visual stimuli and the lower the HRmax during physical exercise, then the lower the chance of SEP completion in ME/CFS.

Graded Exercise Therapy Doesn’t Restore the Ability to Work in ME/CFS. Rethinking of a Cochrane Review

Abstract:

Background: Cochrane recently amended its exercise review for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) in response to an official complaint.

Objective: To determine if the amended review has addressed the concerns raised about the previous review and if exercise is an effective treatment that restores the ability to work in ME/CFS.

Method: The authors reviewed the amended Cochrane exercise review and the eight trials in it by paying particular interest to the objective outcomes. We also summarised the recently published review of work rehabilitation and medical retirement for ME/CFS.

Results: The Cochrane review concluded that graded exercise therapy (GET) improves fatigue at the end of treatment compared to no-treatment. However, the review did not consider the unreliability of subjective outcomes in non-blinded trials, the objective outcomes which showed that GET is not effective, or the serious flaws of the studies included in the review. These flaws included badly matched control groups, relying on an unreliable fatigue instrument as primary outcome, outcome switching, p-hacking, ignoring evidence of harms, etc. The review did also not take into account that GET does not restore the ability to work.

Conclusion: GET not only fails to objectively improve function significantly or to restore the ability to work, but it’s also detrimental to the health of≥50% of patients, according to a multitude of patient surveys. Consequently, it should not be recommended.

The Impact of a Structured Exercise Programme upon Cognitive Function in Chronic Fatigue Syndrome Patients

[Editor’s Note: The dropout rate for this study was 50%. After false discovery rate (FDR) correction, none the results achieved statistical significance.]

Abstract:

BACKGROUND: Cognitive function disturbance is a frequently described symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). In this study, the effects of a structured exercise programme (SEP) upon cognitive function in ME/CFS patients was examined.

METHODS: Out of the 53 ME/CFS patients initiating SEP 34 (64%) completed the 16 week programme. Cognitive function was assessed using a computerized battery test consisting of a Simple Reaction Time (SRT) (repeated three times) and Choice Reaction Time (CRT) measurements, a Visual Attention Test (VAT) and a Delayed Matching to Sample (DMS) assessment.

RESULTS: Statistically significant improvement was noted in the third attempt to SRT in reaction time for correct answers, p = 0.045, r = 0.24. Moreover, significant improvement was noted in VAT reaction time, number of correct answers and errors committed, p = 0.02, omega = 0.03, p = 0.007, r = 0.34 and p = 0.004, r = 0.35, respectively. Non-significant changes were noted in other cognitive tests.

CONCLUSIONS: A substantial number of participants were unwilling or unable to complete the exercise programme. ME/CFS patients able to complete the SEP showed improved visual attention both in terms of reaction time and correctness of responses and processing speed of simple visual stimuli.

Monitoring treatment harm in myalgic encephalomyelitis/chronic fatigue syndrome: A freedom-of-information study of National Health Service specialist centres in England

Abstract:

The use of graded exercise therapy and cognitive behavioural therapy for myalgic encephalomyelitis/chronic fatigue syndrome has attracted considerable controversy. This controversy relates not only to the disputed evidence for treatment efficacy but also to widespread reports from patients that graded exercise therapy, in particular, has caused them harm. We surveyed the National Health Service-affiliated myalgic encephalomyelitis/chronic fatigue syndrome specialist clinics in England to assess how harms following treatment are detected and to examine how patients are warned about the potential for harms.

We sent 57 clinics standardised information requests under the United Kingdom’s Freedom of Information Act. Data were received from 38 clinics. Clinics were highly inconsistent in their approaches to the issue of treatment-related harm. They placed little or no focus on the potential for treatment-related harm in their written information for patients and for staff. Furthermore, no clinic reported any cases of treatment-related harm, despite acknowledging that many patients dropped out of treatment.

In light of these findings, we recommend that clinics develop standardised protocols for anticipating, recording, and remedying harms, and that these protocols allow for therapies to be discontinued immediately whenever harm is identified.

Physical activity patterns among children and adolescents with mild-to-moderate chronic fatigue syndrome/myalgic encephalomyelitis

Abstract:

OBJECTIVE: Chronic fatigue syndromemyalgic encephalomyelitis (CFS/ME) is relatively common among children and adolescents; however, little is known about the physical activity levels and patterns of this population. The aim of this study was to examine the underlying patterns of physical activity among youth with mild-to-moderate CFS/ME. Cross-sectional associations between physical activity patterns with self-reported physical function, pain, fatigue, anxiety and depression were also examined.

DESIGN: Baseline cross-sectional data from the Managed Activity Graded Exercise iN Teenagers and pre-Adolescents randomised controlled trial.

PATIENTS: Children and adolescents (aged 8-17 years) diagnosed with mild-to-moderate CFS/ME who wore an accelerometer for at least three valid weekdays.

ANALYSES: Latent profile analysis was used to identify physical activity patterns. Linear regression models examined associations between physical activity classes and self-reported physical function, pain, fatigue, anxiety and depression.

RESULTS: 138 children and adolescents (72.5% females) had valid data. Overall, participants did less than half the government recommended level of physical activity for children and adolescents, but not all were inactive: three (2.2%) did more than 1 hour of physical activity every day, and 13 (9.4%) achieved an average of 60 min a day. Adolescents (≥12 years) were less active than younger children, but activity levels were similar between genders. Three latent classes emerged from the data: ‘active’, ‘light’ and ‘inactive’. Compared with being ‘inactive’, being in the ‘light’ class was associated with greater self-reported physical function (10.35, 95% CI 2.32 to 18.38) and lower fatigue (-1.60, 95% CI -3.13 to -0.06), while being ‘active’ was associated with greater physical function (15.26, 95% CI 0.12 to 30.40), but also greater anxiety (13.79, 95% CI 1.73 to 25.85).

CONCLUSIONS: Paediatricians need to be aware that physical activity patterns vary widely before recommending treatment.

Graded exercise therapy for myalgic encephalomyelitis/chronic fatigue syndrome is not effective and unsafe. Re-analysis of a Cochrane review

Abstract:

The analysis of the 2017 Cochrane review reveals flaws, which means that contrary to its findings, there is no evidence that graded exercise therapy is effective. Because of the failure to report harms adequately in the trials covered by the review, it cannot be said that graded exercise therapy is safe. The analysis of the objective outcomes in the trials provides sufficient evidence to conclude that graded exercise therapy is an ineffective treatment for myalgic encephalomyelitis/chronic fatigue syndrome.
