Functional improvement is accompanied by reduced pain in adolescent chronic fatigue syndrome

Dear Editor:

Chronic fatigue syndrome (CFS) in adolescents is a complex, disabling condition characterized by severe and unexplained fatigue lasting more than 6 months, and often accompanied by pain symptoms. CFS in adolescents has substantial long-term consequences for educational and social development ⇓.

Chronic pain symptoms in CFS are disabling and affect physical and social functioning ⇓. Adult patients with CFS show lower pain thresholds than healthy subjects ⇓.

In a recently published review about pain in patients with CFS, Nijs et al. stated that pain appears to be one out of many symptoms related to central sensitization in adult CFS ⇓. They concluded that pain-catastrophizing thoughts and depression partly account for these pain symptoms. They suggested that it is important to understand the symptoms of pain in CFS better in order to assess whether it requires a specific treatment approach other than the main treatment focused on fatigue ⇓. Previous research has suggested to view the pathophysiological state of pain in CFS as an increase in the excitability and synaptic efficacy of neurons in central nociceptive pathways ⇓. We present original data on pain symptoms in adolescent CFS and their relation to treatment focused on fatigue.

We hypothesized that adolescent CFS patients have a lowered pain threshold at the time of diagnosis and that both pain experience and pain threshold improve when CFS is successfully treated.

Use of an online survey to explore positive and negative outcomes of rehabilitation for people with CFS/ME

Abstract:

PURPOSE:First, to explore the experiences of people with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) of rehabilitation therapies so as to build an understanding of reasons for the discrepancy between the notably mixed experiences regarding effectiveness reported in patient surveys and the RCT evidence about the efficacy of Graded Exercise Therapy (GET). GET is a form of structured and supervised activity management that aims for gradual but progressive increases in physical activity. Second, to review patient experiences of two related rehabilitation approaches, Exercise on Prescription (EoP) and Graded Activity Therapy (GAT).

METHOD: An online survey conducted by the charity Action for ME generated qualitative data about 76 patient experiences of rehabilitation undertaken during or after 2008, examined using thematic analysis.

RESULTS: Both positive and negative experiences of rehabilitation were reported. Positive themes included supportive communication, the benefits of a routine linked with baseline setting and pacing, the value of goal setting, and increasing confidence associated with exercise. Negative themes included poor communication, feeling pushed to exercise beyond a sustainable level, having no setback plan, and patients feeling blamed for rehabilitation not working.

CONCLUSIONS: The negative themes may help explain the negative outcomes from rehabilitation reported by previous patient surveys. The negative themes indicate rehabilitation processes which contradict the NICE (National Institute for Health and Clinical Excellence) Guideline advice regarding GET, indicating that some clinical encounters were not implementing these. These findings suggest areas for improving therapist training, and for developing quality criteria for rehabilitation in CFS/ME.

Implications for Rehabilitation: The insensitive delivery of rehabilitation support for people with CFS/ME can explain negative outcomes reported in patient surveys. Therapist-patient collaboration, establishing a sustainable baseline and agreeing a setback plan are all examples of higher quality rehabilitation indicated by this research. Greater awareness of the positive and negative experiences of rehabilitation therapies should enable avoidance of the potential pitfalls identified in this research.

Positive experiences of rehabilitation therapies include supportive communication with a therapist, treatment which included routines and goals, and value attached to baselines and controlled pacing. By contrast, factors leading to negative experiences include poor communication and support, conflict in beliefs about CFS/ME and rehabilitation, pressure to comply with treatment, worsening of symptoms, baselines experienced as unsustainable, and feeling blamed for rehabilitation not working.

Cost-effectiveness of counselling, graded-exercise and usual care for chronic fatigue: evidence from a randomised trial in primary care

Abstract:

BACKGROUND: Fatigue is common and has been shown to result in high economic costs to society. The aim of this study is to compare the cost-effectiveness of two active therapies, graded-exercise (GET) and counselling (COUN) with usual care plus a self-help booklet (BUC) for people presenting with chronic fatigue.

METHODS: A randomised controlled trial was conducted with participants consulting for fatigue of over three months’ duration recruited from 31 general practices in South East England and allocated to one of three arms. Outcomes and use of services were assessed at 6-month follow-up. The main outcome measure used in the economic evaluation was clinically significant improvements in fatigue, measured using the Chalder fatigue scale. Cost-effectiveness was assessed using the net-benefit approach and cost-effectiveness acceptability curves.

RESULTS: Full economic and outcome data at six months were available for 163 participants; GET = 51, COUN = 58 and BUC = 54. Those receiving the active therapies (GET and COUN) had more contacts with care professionals and therefore higher costs, these differences being statistically significant. COUN was more expensive and less effective than the other two therapies. The incremental cost-effectiveness ratio of GET compared to BUC was equal to £987 per unit of clinically significant improvement. However, there was much uncertainty around this result.

CONCLUSION: This study does not provide a clear recommendation about which therapeutic option to adopt, based on efficiency, for patients with chronic fatigue. It suggests that COUN is not cost-effective, but it is unclear whether GET represents value for money compared to BUC.

Adaptive pacing, cognitive behaviour therapy, graded exercise, and specialist medical care for chronic fatigue syndrome: a cost-effectiveness analysis

Abstract:

BACKGROUND: The PACE trial compared the effectiveness of adding adaptive pacing therapy (APT), cognitive behaviour therapy (CBT), or graded exercise therapy (GET), to specialist medical care (SMC) for patients with chronic fatigue syndrome. This paper reports the relative cost-effectiveness of these treatments in terms of quality adjusted life years (QALYs) and improvements in fatigue and physical function.

METHODS: Resource use was measured and costs calculated. Healthcare and societal costs (healthcare plus lost production and unpaid informal care) were combined with QALYs gained, and changes in fatigue and disability; incremental cost-effectiveness ratios (ICERs) were computed.

RESULTS: SMC patients had significantly lower healthcare costs than those receiving APT, CBT and GET. If society is willing to value a QALY at £30,000 there is a 62.7% likelihood that CBT is the most cost-effective therapy, a 26.8% likelihood that GET is most cost effective, 2.6% that APT is most cost-effective and 7.9% that SMC alone is most cost-effective. Compared to SMC alone, the incremental healthcare cost per QALY was £18,374 for CBT, £23,615 for GET and £55,235 for APT. From a societal perspective CBT has a 59.5% likelihood of being the most cost-effective, GET 34.8%, APT 0.2% and SMC alone 5.5%. CBT and GET dominated SMC, while APT had a cost per QALY of £127,047. ICERs using reductions in fatigue and disability as outcomes largely mirrored these findings.

CONCLUSIONS: Comparing the four treatments using a health care perspective, CBT had the greatest probability of being the most cost-effective followed by GET. APT had a lower probability of being the most cost-effective option than SMC alone. The relative cost-effectiveness was even greater from a societal perspective as additional cost savings due to reduced need for informal care were likely.

Unidentified Chronic Fatigue Syndrome/myalgic encephalomyelitis (CFS/ME) is a major cause of school absence: surveillance outcomes from school-based clinics

Abstract:

Objective To investigate the feasibility of conducting clinics for chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) in schools.

Design School-based clinical project. Participants Children aged 11-16 years were enrolled in three state secondary schools in England.

Main outcome measures Number of children newly diagnosed as having CFS/ME.

Methods Attendance officers identified children missing ≥20% of school in a 6-week term without a known cause, excluding those with a single episode off school, a known medical illness explaining the absence or known to be truanting. Children with fatigue were referred to a specialist CFS/ME service for further assessment. The authors compared children with CFS/ME identified through school-based clinics with those referred via health services. Outcomes of CFS/ME were evaluated at 6 weeks and 6 months.

Results 461 of the 2855 enrolled children had missed ≥20% school over a 6-week period. In 315, of whom three had CFS/ME, the reason for absence was known. 112 of the 146 children with unexplained absence attended clinical review at school; two had been previously diagnosed as having CFS/ME and 42 were referred on to a specialist clinic, where 23 were newly diagnosed as having CFS/ME. Therefore, 28 of the 2855 (1.0%) children had CFS/ME. Children with CFS/ME identified through surveillance had been ill for an amount of time comparable to those referred via health services but had less fatigue (mean difference 4.4, 95% CI 2.2 to 6.6), less disability (mean difference -5.7, 95% CI -7.9 to -3.5) and fewer symptoms (mean difference 1.86, 95% CI 0.8 to 2.93). Of 19 children followed up, six had fully recovered at 6 weeks and a further six at 6 months.

Conclusions Chronic fatigue is an important cause of unexplained absence from school. Children diagnosed through school-based clinics are less severely affected than those referred to specialist services and appear to make rapid progress when they access treatment.

Cognitive behavioural treatment for chronic fatigue syndrome in a rehabilitation setting: effectiveness and predictors of outcome

Abstract:

Cognitive behavioural therapy (CBT) was combined with graded exercise therapy (GET) for patients with chronic fatigue syndrome (CFS) in an uncontrolled implementation study of an inpatient multidisciplinary group therapy.

During the intake procedure, 160 CFS patients completed a questionnaire on fatigue related measurements, physical impairment, depression, somatic and psychological attributions, somatic focus, and sense of control over symptoms. Pre-treatment physical activity level was measured with an actometer. At baseline, post-treatment and 6-month follow-up individual strength, subjective fatigue and physical impairment, were reassessed. Large effect sizes were found on subjective fatigue (1.2 post-treatment; 1.2 follow-up) and physical impairment (-.9 post-treatment; -.9 follow-up).

Clinically significant improvement was found in 33.8% of the participants at post-treatment and 30.6% at follow-up. Individual strength at post-treatment was predicted by level of physical activity before treatment, and by sense of control over symptoms and physical activity at follow-up. Clinically significant improvement in subjective fatigue was predicted by not receiving a disablement insurance benefit, shorter duration of fatigue, higher sense of control over symptoms and, at follow-up by more pre-treatment physical activity. In conclusion, the intervention was effective for CFS patients. Cognitive behavioural factors that perpetuate fatigue symptoms are also predictors of treatment outcome.

Comparison of adaptive pacing therapy, cognitive behaviour therapy, graded exercise therapy, and specialist medical care for chronic fatigue syndrome (PACE): a randomised trial

Abstract:

BACKGROUND: Trial findings show cognitive behaviour therapy (CBT) and graded exercise therapy (GET) can be effective treatments for chronic fatigue syndrome, but patients’ organisations have reported that these treatments can be harmful and favour pacing and specialist health care. We aimed to assess effectiveness and safety of all four treatments.

METHODS: In our parallel-group randomised trial, patients meeting Oxford criteria for chronic fatigue syndrome were recruited from six secondary-care clinics in the UK and randomly allocated by computer-generated sequence to receive specialist medical care (SMC) alone or with adaptive pacing therapy (APT), CBT, or GET. Primary outcomes were fatigue (measured by Chalder fatigue questionnaire score) and physical function (measured by short form-36 subscale score) up to 52 weeks after randomisation, and safety was assessed primarily by recording all serious adverse events, including serious adverse reactions to trial treatments. Primary outcomes were rated by participants, who were necessarily unmasked to treatment assignment; the statistician was masked to treatment assignment for the analysis of primary outcomes. We used longitudinal regression models to compare SMC alone with other treatments, APT with CBT, and APT with GET. The final analysis included all participants for whom we had data for primary outcomes. This trial is registered at http://isrctn.org, number ISRCTN54285094.

FINDINGS: We recruited 641 eligible patients, of whom 160 were assigned to the APT group, 161 to the CBT group, 160 to the GET group, and 160 to the SMC-alone group. Compared with SMC alone, mean fatigue scores at 52 weeks were 3·4 (95% CI 1·8 to 5·0) points lower for CBT (p = 0·0001) and 3·2 (1·7 to 4·8) points lower for GET (p = 0·0003), but did not differ for APT (0·7 [-0·9 to 2·3] points lower; p = 0·38). Compared with SMC alone, mean physical function scores were 7·1 (2·0 to 12·1) points higher for CBT (p = 0·0068) and 9·4 (4·4 to 14·4) points higher for GET (p = 0·0005), but did not differ for APT (3·4 [-1·6 to 8·4] points lower; p=0·18). Compared with APT, CBT and GET were associated with less fatigue (CBT p = 0·0027; GET p = 0·0059) and better physical function (CBT p=0·0002; GET p<0·0001). Subgroup analysis of 427 participants meeting international criteria for chronic fatigue syndrome and 329 participants meeting London criteria for myalgic encephalomyelitis yielded equivalent results. Serious adverse reactions were recorded in two (1%) of 159 participants in the APT group, three (2%) of 161 in the CBT group, two (1%) of 160 in the GET group, and two (1%) of 160 in the SMC-alone group.

INTERPRETATION: CBT and GET can safely be added to SMC to moderately improve outcomes for chronic fatigue syndrome, but APT is not an effective addition.

Health-related quality of life in patients with chronic fatigue syndrome: group cognitive behavioural therapy and graded exercise versus usual treatment. A randomised controlled trial with 1 year of follow-up

Abstract:

Chronic fatigue syndrome (CFS) produces physical and neurocognitive disability that significantly affects health-related quality of life (HRQL). Multidisciplinary treatment combining graded exercise therapy (GET) cognitive behavioural therapy (CBT) and pharmacological treatment has shown only short-term improvements.

Aim: To compare the effects on HRQL of (1) multidisciplinary treatment combining CBT, GET, and pharmacological treatment, and (2) usual treatment (exercise counselling and pharmacological treatment) at 12 months of follow-up.

Design: Prospective, randomized controlled trial with a follow-up of 12 months after the end of treatment.

Method: Patients consecutively diagnosed with CFS (Fukuda criteria) were randomly assigned to intervention (n = 60) or usual treatment (n = 60) groups. HRQL was assessed at baseline and 12 months by the Medical Outcomes Study Short-Form questionnaire (SF-36). Secondary outcomes included functional capacity for activities of daily living measured by the Stanford Health Assessment Questionnaire (HAQ) and comorbidities.

Results: At baseline, the two groups were similar, except for lower SF-36 emotional role scores in the intervention group. At 12 months, the intervention did not improve HRQL scores, with worse SF-36 physical function and bodily pain scores in the intervention group.

Conclusion: Multidisciplinary treatment was not superior to usual treatment at 12 months in terms of HRQL. The possible benefits of GET as part of multidisciplinary treatment for CFS should be assessed on an individual patient basis.

Graded exercise for chronic fatigue syndrome: too soon to dismiss reports of adverse reactions

Sir,

Given there is no formal system to report adverse reactions to non-pharmacological interventions such as graded exercise therapy (GET) for chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), other sources of data need to be considered when evaluating safety. As noted by Clark & White, a large survey conducted in 2001 by the charity Action for ME found that 50% of patients who received graded exercise felt worse (1, 2). They also referred to a subsequent study by the same group suggesting that many patients might not have been treated by experienced therapists (3). However, the sample was small and, as in all surveys, therapist competence was not assessed.

A review of all the surveys conducted to date not only supports the view that a significant proportion of patients experience adverse reactions following GET, but also that it is premature to attribute those reactions to practitioner inexperience or inadequate training (1, 4). For example, the results of a recent survey conducted by the ME Association showed that of the 906 individuals who had received GET, 33.1% felt “much worse” and 23.4% judged themselves to be “slightly worse” (4). Similarly, a survey of patients who had been treated in the previous 3 years, i.e. following the refinement of the protocol as discussed by Clark & White, revealed that 34% of the 722 who had tried GET perceived themselves to be worse (5).

Without details of the training of the therapist and their fidelity to the treatment manual, one can only speculate about the factors associated with poor outcome. Nijs et al. (6) discussed some of the possible reasons. However, there are additional factors that deserve consideration when evaluating the efficacy and safety of GET. Firstly, the survey results may reflect, at least in part, the experiences of patients receiving treatment in a clinical setting. As has been shown in studies on other interventions, the outcomes documented in routine practice may be more realistic than those obtained in randomized controlled trials (7). Secondly, many patients may not be able to complete graded activity schedules for various reasons, including ongoing pathology. For instance, Black & McCully (8) used an accelerometer to measure activity levels before, during and after a 4-week “training period” consistent with GET. They documented an increase in activity counts lasting between 4 and 10 days, and this was associated with higher scores for pain and fatigue. The inability to sustain target activity levels was also noted by Friedberg (9), who followed the progress of one patient during 26 sessions of GET. He recorded a 10.6% decrease in mean weekly step counts, leading Friedberg to speculate that the subjective measures of improvement might have been the result of activity substitution and a corresponding reduction in perceived stress.

Finally, we were surprised that neither of the letters cited the research by White et al. (10). This elegant study supports the growing evidence of abnormal metabolic and immunological reactions to exercise in subsets with CFS. Although their sample was small, White et al. found elevated concentrations of the pro-inflammatory cytokine tumour necrosis factor-alpha at time-points of 3 h and 3 days after exercise. In addition, they documented increased levels of the anti-inflammatory cytokine transforming growth factor-beta after normal exertion. We therefore concur with Nijs et al. (6) as well as other researchers, that GET may not be appropriate for all patients with CFS and that pacing may provide a useful, acceptable and safe alternative (6, 11, 12).

Chronic fatigue syndrome: la bête noire of the Belgian health care system

Abstract:

The World Health Organization acknowledges Myalgic Encephalomyelitis (ME)/Chronic Fatigue Syndrome (CFS) to be a medical illness. ME/CFS is characterized by disorders in the inflammatory and oxidative and nitrosative stress (IO&NS) pathways. In 2002, the Belgian government started with the development of CFS “Reference Centers”, which implement a “psychosocial” model. The medical practices of these CFS Centers are defined by the Superior Health Council, e.g. treatment should be based upon Cognitive Behavioral Therapy (CBT) and Graded Exercise Therapy (GET); and biological assessments and treatments of ME/CFS should not be employed.

Recently, the Belgian government has evaluated the outcome of the treatments at the CFS Centers. They concluded that a “rehabilitation therapy” with CBT/GET yielded no significant efficacy in the treatment of ME/CFS and that CBT/GET cannot be considered to be curative therapies.

In case reports, we have shown that patients who were “treated” at those CFS centers with CBT/GET in fact suffered from IO&NS disorders, including intracellular inflammation, an increased translocation of gram-negative enterobacteria (leaky gut), autoimmune reactions and damage by O&NS.

Considering the fact that these findings are exemplary for ME/CFS patients and that GET may even be harmful, it means that many patients are maltreated by the Belgian CFS Centers. Notwithstanding the above, the government and the CFS Centers not only continue this unethical and immoral policy, but also reinforce their use of CBT/GET in patients with ME/CFS treated at those Centers.
