Cognitive behaviour therapy for the chronic fatigue syndrome. Essential elements of the treatment must be identified

Comment on: Cognitive behaviour therapy for the chronic fatigue syndrome: a randomized controlled trial. [BMJ. 1996]

 

EDITOR,-We have several practical and theoretical concerns about Michael Sharpe and colleagues’ study of cognitive behaviour therapy in the chronic fatigue syndrome.’ The authors managed to obtain almost 100% uptake of treatment and compliance among patients who were attending an infectious diseases clinic and were strongly convinced that their chronic fatigue had a physical cause. We would struggle to engage our patients similarly, even with two hours for an initial appointment, and we could not offer them anything approaching an hour of treatment a week for four months. The difference between what was provided in the study and what clinicians can routinely offer their patients makes it important to identify the essential elements of the treatment.

The package given included cognitive techniques such as “question[ing] a simple disease explanation,” “strategies to reduce excessive perfectionism and self criticism,” and a problem solving approach of “gradual and consistent increases in activity.” The continuing improvement after the end oftreatment is unusual for the cognitive psychotherapies and suggests that the behavioural component was most effective. We find it puzzling, therefore, that the authors attribute the beneficial effects of treatment to “a specific effect on illness perpetuating beliefs and coping behaviour,” particularly as these attitudes did not change substantially. The patients would inevitably report less avoidance of exercise if they were complying with the study. After treatment at least half of the patients still believed that the illness was physical (from tables 2 and 5), and the vast majority still applied the damaging label of “myalgic encephalomyelitis”2 to their condition.

Cognitive behaviour therapy for the chronic fatigue syndrome. Cognitive behavior therapy should be compared with placebo treatments

Comment on: Cognitive behaviour therapy for the chronic fatigue syndrome: a randomized controlled trial. [BMJ. 1996]

 

EDITOR,-Lest Michael Sharpe and colleagues’ paper lends respectability to the notion that the chronic fatigue syndrome is a diagnostic entity or suggests that cognitive behaviour therapy has any value specific to the condition,1 I wish to make three points.

Firstly, the disorder that the authors treated is heterogeneous, the only defining criteria used being fatigue, impaired daily activities, and the absence of signs of physical disease or “severe depression.” Claims for a specific effect in any diffuse symptom complex are dangerous. Quinine is effective in many cases of cramp, but neither the symptom nor the benefit is specific.

Secondly, cognitive behaviour therapy and any comparable substitute were denied the control patients, who were therefore matched only on pretreatment criteria regarding their clinical state and not controlled in respect of a comparable treatment. Despite the authors’ claim for a “specificity of treatment effect” the benefits shown are consistent with the provision of much attention, encouragement, and a positive attitude to the nature of the illness and the strategies to counter it.’

Cognitive behaviour therapy for the chronic fatigue syndrome. Use an interdisciplinary approach

Comment on: Cognitive behaviour therapy for the chronic fatigue syndrome: a randomized controlled trial. [BMJ. 1996]

 

EDITOR,-From their randomised trial in the chronic fatigue syndrome Michael Sharpe and colleagues conclude that cognitive behaviour therapy is more effective than “medical care” in improving day to day function.1 It is not clear that the data presented justify this conclusion. Firstly, the authors do not compare like with like: the group given cognitive behaviour therapy received 16 hours of therapy while the “medical” group received no intervention. Secondly, the “medical” group of patients were “advised to increase their level of activity by as much as they felt able,” which may have had adverse effects if the activity was unsupervised and inappropriate.2 This could have affected the results by making the group given cognitive behaviour therapy seem to improve by more than they did. Thirdly, all patients, and particularly those with the chronic fatigue syndrome, need detailed discussion of their problems. Many doctors will not have been aware that in providing such discussion-surely the duty of all doctors-they were in part providing cognitive behaviour therapy.

Cognitive behaviour therapy for the chronic fatigue syndrome. Patients were not representative of all patients with the syndrome.

Comment on: Cognitive behaviour therapy for the chronic fatigue syndrome: a randomized controlled trial. [BMJ. 1996]

 

EDITOR,-Michael Sharpe and colleagues conclude that cognitive behaviour therapy leads to a sustained reduction in functional impairment for patients with the chronic fatigue syndrome.1 The levels of disability of the 60 patients who took part in the study suggest, however, that these patients do not represent a comprehensive cross section of patients with the syndrome. The 60 patients scored 60-78 on the Karnofsky scale assessing disability and so represent a different population from the 143 patients reported on by Case History Research on ME (myalgic encephalomyelitis), who would have scored 30-60 (R Gibbons et al, first world congress on chronic fatigue syndrome and related disorders, Brussels, Nov 1995). Fifty nine of these 143 patients reported functional deterioration after sustained, incrementally increased physical exertion.

The authors did not assess other symptoms common in the chronic fatigue syndrome, such as pain, nausea, muscle weakness, or balance problems-a measure of the reduction of which was taken as a standard for “success” in an earlier trial.2 The lack of evidence of significant changes in other measures besides “the principal complaint of severe fatigue” in the authors’ study tends to diminish the validity of their conclusions.

Cognitive behaviour therapy for the chronic fatigue syndrome. Evening primrose oil and magnesium have been shown to be effective

EDITOR,-In their paper on cognitive behaviour therapy for the chronic fatigue syndrome Michael Sharpe and colleagues state that many pharmacological treatments have been suggested but none are of proved value.1 Last year Lewith stated that the only two treatments that had been properly evaluated were evening primrose oil and magnesium by injection.2 Intramuscular magnesium supplements have been given to patients with low red cell magnesium in a double blind placebo controlled trial; myalgia and fatigue improved in about 70% of subjects.3 Evening primrose oil has been used to treat myalgic encephalomyelitis and is the only other treatment that has been adequately tested in a controlled trial. High doses in randomised controlled trials have been shown to have a significant effect in 70-80% of patients with myalgic encephalomyelitis or the chronic fatigue syndrome.4 I would be interested to hear Sharpe and colleagues’ comments about these papers.

Cognitive behaviour therapy for the chronic fatigue syndrome: a randomized controlled trial

Abstract:

OBJECTIVE: To evaluate the acceptability and efficacy of adding cognitive behaviour therapy to the medical care of patients presenting with thechronic fatigue syndrome.

DESIGN: Randomised controlled trial with final assessment at 12 months.

SETTING: An infectious diseases outpatient clinic.

SUBJECTS: 60 consecutively referred patients meeting consensus criteria for the chronic fatigue syndrome.

INTERVENTIONS: Medical care comprised assessment, advice, and follow up in general practice. Patients who received cognitive behaviour therapy were offered 16 individual weekly sessions in addition to their medical care.

MAIN OUTCOME MEASURES: The proportions of patients (a) who achieved normal daily functioning (Karnofsky score 80 or more) and (b) who achieved a clinically significant improvement in functioning (change in Karnofsky score 10 points or more) by 12 months after randomisation.

RESULTS: Only two eligible patients refused to participate. All randomised patients completed treatment. An intention to treat analysis showed that 73% (22/30) of recipients of cognitive behaviour therapy achieved a satisfactory outcome as compared with 27% (8/30) of patients who were given only medical care (difference 47 percentage points; 95% confidence interval 24 to 69). Similar differences were observed in subsidiary outcome measures. The improvement in disability among patients given cognitive behaviour therapy continued after completion of therapy. Illness beliefs and coping behaviour previously associated with a poor outcome changed more with cognitive behaviour therapy than with medical care alone.

CONCLUSION: Adding cognitive behaviour therapy to the medical care of patients with the chronic fatigue syndrome is acceptable to patients and leads to a sustained reduction in functional impairment.

Chronic fatigue syndrome: a cognitive approach

Abstract:

Observations concerning the characteristics of patients who presented to a medical clinic with a principal complaint of chronic medically unexplained fatigue (Chronic Fatigue Syndrome or CFS) are described, including the cognitions (thoughts and assumptions) elicited from a sample of these patients who were treated using cognitive behavioural therapy. On the basis of these observations a cognitive theory of the aetiology of CFS is proposed. These observations have implications for the treatment of patients with CFS.

Chronic fatigue syndrome. Clinical, social psychological problems and management

Abstract:

Fatigue chronic syndrome (SFC) is the heir-at-law of neurasthenia. Both are seen like physical diseases and share certain therapeutic measures, such as sleep; they have the same symbolic function and enable patients as well as doctors reluctant to psychological dimensions of pathology, to get and express sympathy and attention. A strong controversy developed these last years concerning the SFC physiopathology particularly concerning the responsibility of viral infectious agents or psychiatric troubles.

The SFC fatigue is unlikely hysterical or neuromuscular but it probably depends on several associated factors; cerebral neurobiochemistry anomalies (possibly induced by an infection or immune reactions), effort perception trouble, affective trouble, lack of physical activity. The handicap seems to be worse on account of unsuitable care and inefficacious treatment. Especially sleep, which is often beneficial in a short term, is source of ulterior chronicisation. Antidepressants are the only justified pharmacological treatment for SFC at the moment. Referring to the existence and the nature of cognitive distortions, the author suggests a cognitive-behavioural therapy, whose aim is a progressive activity resumption.

Therapeutic guidelines in chronic fatigue syndrome

Abstract:

The treatment of CFS is not definitive up till now and it is limited both by ignorance of its causes and by different applicable operative case definitions. It has been etiopathologically related to infectious agents, neuromuscular illnesses, neuro-endocrinous-immunologic alterations and to different psychiatric disorders, particularly depressive disorders. Consequently, a great variety of therapeutic strategies have been tried, most of them with insufficient results. Among the medicamentous ones: immunity activator agents such as recombinant interleukin-2, nonspecific immunitary modulators such as seric gamma globulin, antivirus drugs such as acyclovir, muscular relaxants such as ciclobenzaprine, H2 receptor blockers and steroid and nonsteroid anti-inflammatory drugs such as ibuprofen, naproxen and fulbiprofen. Better results seem to have been obtained with antidepressants, and amfebutamone and serotonin-reuptake selective inhibitors are specially promising. Among the nonmedicamentous strategies, cognitive behavioural treatment can be effective and the so called “psychiatric management of the patient with CFS” has been proposed as a global, pragmatic, individualized, comprehensive approach which must be completed with other interdisciplinary interventions on the patient and his environment.

A comparison of cognitive behavioral treatment for chronic fatigue syndrome and primary depression

Abstract:

To evaluate the effect of cognitive behavioral intervention on chronic fatigue syndrome (CFS), we studied three patient groups: a CFS-treatment group (n = 22), a primary depression-treatment group (n = 20), and a no-treatment control group of subjects with CFS (n = 22). For the CFS-treatment group, a trend toward reduced depression-symptom scores was noted, but there were no significant changes in stress-related symptoms or fatigue severity.

For the most depressed treated subjects with CFS, significant score reductions were observed in measures of depression, stress, fatigue severity, and fatigue-related thinking. In the depression group, significant reductions in depression, stress, and fatigue severity scores were found. No significant changes in any measure were observed in the CFS control group.

A new fatigue-related cognitions scale, developed to assess cognitive and emotional reactions to fatigue, showed a significant reduction in such reactions in the CFS-treatment group, a finding suggesting that depression in this group was mediated by maladaptive thinking. The results suggest that a subset of CFS patients with cognition-related depressive symptomatology may respond to short-term behavioral intervention.
