Chronic fatigue syndrome and health control in adolescents and parents

Abstract:

AIMS: To explore the locus of health control in adolescents with chronic fatigue syndrome (CFS) and their parents in comparison with healthy adolescents and their parents.

METHODS: In this cross-sectional study 32 adolescents with CFS were compared with 167 healthy controls and their respective parents. The Multidimensional Health Locus of Control (MHLC) questionnaire was applied to all participants.

RESULTS: There was significantly less internal health control in adolescents with CFS than in healthy controls. An increase of internal health control of one standard deviation was associated with a 61% reduced risk for CFS (OR = 0.39, 95% CI 0.25 to 0.61). Internal health control of the parents was also protective (OR fathers: 0.57 (95% CI 0.38 to 0.87); OR mothers: 0.74 (95% CI 0.50 to 1.09)). The external loci of health control were higher in adolescents with CFS and in their parents. Increased levels of fatigue (56%) were found in the mothers of the adolescents with CFS, in contrast with the fathers who reported a normal percentage of 13.

CONCLUSIONS: In comparison with healthy adolescents, adolescents with CFS and their parents show less internal health control. They attribute their health more to external factors, such as chance and physicians. This outcome is of relevance for treatment strategies such as cognitive behaviour therapy, for which health behaviour is the main focus.

Is the chronic fatigue syndrome an exercise phobia? A case control study

Abstract:

OBJECTIVE: The aim of this study was to test whether patients with chronic fatigue syndrome (CFS) have an exercise phobia, by measuring anxiety-related physiological and psychological reactions to ordinary activity and exercise.

METHODS: Patients and healthy but sedentary controls were assessed over 8 h of an ordinary day, and before, during and after an incremental exercise test on a motorised treadmill. To avoid confounding effects, those with a comorbid psychiatric disorder were excluded. Heart rate, galvanic skin resistance (GSR) and the amount of activity undertaken were measured, along with state and trait measures of anxiety.

RESULTS: Patients with CFS were more fatigued and sleep disturbed than were the controls and noted greater effort during the exercise test. No statistically significant differences were found in either heart rate or GSR both during a normal day and before, during and after the exercise test. Patients with CFS were more symptomatically anxious at all times, but this did not increase with exercise.

CONCLUSION: The data suggest that CFS patients without a comorbid psychiatric disorder do not have an exercise phobia.

Cognitive behaviour group therapy for chronic fatigue syndrome: a non-randomised waiting list controlled study

Abstract:

BACKGROUND: It has been demonstrated that individual cognitive behaviour therapy is an effective treatment for chronic fatigue syndrome(CFS). The aim of the present study was to investigate the effectiveness of cognitive behaviour group therapy (CBGT) in an unselected group of CFS patients. Additionally, pretreatment characteristics of CFS patients who improve after CBGT were explored.

METHODS: In a non-randomised waiting list controlled design, 31 patients were allocated to CBGT and 36 to the waiting list condition. CBGT consisted of 12 two-hour sessions during 6 months. Main outcome measures were fatigue (Checklist Individual Strength) and functional impairment (Sickness Impact Profile).

RESULTS: A moderate effect on fatigue in favour of CBGT was found. For functional impairment, the effect was opposite to what was expected. Patients who improved after CBGT had less complaints at baseline compared to patients who did not improve.

CONCLUSIONS: An explanation for the moderate effect might be that during CBGT, rest and relaxation were too much emphasised. Furthermore, an unselected group of CFS patients and therapists inexperienced in CB(G)T for CFS participated. Suggestions to improve CBGT for future research are given.

Significance of the chronic fatigue syndrome in rehabilitation medicine–status and perspectives

Abstract:

It appears that from a clinical point of view chronic exhaustion or fatigue is an important factor in rehabilitation. This is, however, first of all a phenomenon that can be described as a function in accordance with the International Classification of Functioning, Disability and Health (JCF), caused by chronic illnesses or chronic excessive stress. The clinical and sociomedical ranking of chronic fatigue or exhaustion in respect of rehabilitation was discussed in the framework of a Workshop at the 12th Rehabilitation Science Colloquium, 2003 from the viewpoints of psychiatric rehabilitation, methodology, sociology and practical rehabilitation, and conclusions for future research were drawn. The definition of chronic fatigue is first of all mainly based on the feeling of chronic tiredness but also on phenomena of disturbed concentration, physical discomfort, headache and disorders of “drive” and mood.

A psychiatric diagnosis linked with symptoms of chronic fatigue is neurasthenia, which is arrived at according to precisely defined criteria. Depressive disorder is one of the most important differential diagnoses in this sphere. Examinations by general practitioners revealed that about 90 % of the patients who had been diagnosed as suffering from psychovegetative disorders completely agreed with the diagnosis of neurasthenia. Neurasthenia resulted more often in work disability periods than disorders of somatisation and other psychosomatic diagnoses. Basing on the “IRES” scale “vital exhaustion”, singular of even serious changes become evident in about 50 % to 90 % of the patients undergoing rehabilitation, depending on their individual range of indications. As was to be expected, the majority of pathologic findings concerns patients undergoing psychosomatic rehabilitation, since in such cases there is an overlapping with symptoms of psychosomatic diseases.

It is, however, remarkable that also in somatically oriented orthopaedic rehabilitation symptoms of fatigue are seen in up to 50 % of the patients. Preliminary studies have shown that these symptoms can be definitely ameliorated within the rehabilitation framework, although pathological signs are still abundantly apparent in follow-up examinations. Markedly severe degrees of “vital exhaustion” and “vocational exhaustion” are also seen in rheumatology patients undergoing somatic rehabilitation. This agrees with case history details related by many female and male patients.

Hence, it appears necessary to adapt rehabilitative intervention to both the psychovegetative and the medical behavioural aspects of this symptom. Scientific classification of the entire sphere of chronic fatigue in respect of rehabilitation requires classification of the relevant functions within the ICF framework. To this end it would be necessary to conduct patient inquiries within cross-sectional studies on the one hand and, on the other, a systematic consensus process among experts would have to be used for allocation to the relevant functions. This is the basis for development of suitable assessment tools for use in prospective studies in order to systematically evaluate the impact on functions and especially their effects on activities and participation.

Report from the Health Council of the Netherlands on the chronic fatigue syndrome: moving away from the body-mind dichotomy with a view to effective prevention and treatment

Abstract:

The Health Council of the Netherlands has issued a report on the chronic fatigue syndrome (CFS). CFS is a real and seriously debilitating condition which imposes limitations on an individual’s personal, occupational and social functioning. It is a syndrome of unknown aetiology without physical signs or biological markers. Although there is no disease, patients both feel ill and give the appearance of being ill. There is no consensus on whether CSF patients are able to work or whether they should be entitled to social security benefits. An imbalance between demand and coping is central in CFS, with stress as an important intermediary factor. It is little use concluding that unexplained signs are ‘psychological’ or that ‘I cannot find anything wrong with you so you must be healthy’. The classical view that mind and body are separate systems is outmoded. The bio-psycho-social model of disease may be helpful in describing the interaction between body, mind and circumstance. Putting the CFS patient at ease and explaining the pathophysiology of the symptoms is a useful approach but many patients and patient associations are still very somatically orientated, thereby sustaining the condition. However, in patients who accept that their problems may be stress-induced and are prepared to participate in therapy, some therapies have been proven to be effective, notably cognitive behavioural therapy.

Cognitive behaviour therapy for adolescents with chronic fatigue syndrome: data are insufficient and conclusion inappropriate

Comment on: Cognitive behaviour therapy for adolescents with chronic fatigue syndrome: randomised controlled trial. [BMJ. 2005]

 

Editor—I have concerns about the design and interpretation of the study reported by Stulemeijer et al on cognitive behaviour therapy for adolescents with chronic fatigue syndrome.1 The trial arms were not matched for the number of contacts with healthcare professionals. Experience from larger and more carefully controlled randomised interventional trials of patients with chronic fatigue syndrome has clearly shown that short term improvement in symptoms is related directly to the maintenance of regular contacts with healthcare professionals rather than the therapeutic effect of the intervention itself and consequently, the improvement is not sustained once the contact is lost.2

The authors did not offer patients in their waiting list the opportunity to meet therapists regularly for five months but without having cognitive behaviour therapy. Few follow up data on patients in the intervention arm show that the specific treatment benefit was carried forward without regular contacts with the therapists. A cautious approach is essential in inferring direct benefit from cognitive behaviour therapy in the intervention arm (as opposed to short term benefit from close contact with therapists). The level of activity in some of their participants whom the authors considered to be passive remained unclear.

Predictors of outcome following treatment for chronic fatigue

Abstract:

We explored the role of baseline characteristics of 105 patients who presented with fatigue in primary care in determining outcome following either graded exercise or cognitive-behavioural therapy. Meeting the criteria for chronic fatigue syndrome was the most powerful predictor of poor outcome and this negative effect was enhanced by greater functional impairment or greater perceived negative consequences, but was not further enhanced by both.

Subjective quality of life in patients with chronic fatigue syndrome

Abstract:

The aim of this study was to (1) assess Subjective Quality of Life (SQOL) of patients with Chronic Fatigue Syndrome (CFS) using a generic concept and to compare the findings with those in groups with mental disorders and healthy subjects, and (2) investigate whether and, if so, to what extent socio-demographic and clinical variables predict SQOL in CFS patients.

Seventy-three patients diagnosed with CFS were randomly selected and interviewed from two specialised clinics. CFS was diagnosed using the Oxford Criteria. SQOL was assessed on the Manchester Short Assessment of Quality of Life (MANSA) and Health-Related Quality of Life (HRQOL) on the Medical Outcome Study Short-Form 36 (MOS) SF-36. A battery of mood and symptom questionnaires, including the Symptom Checklist Questionnaire (SCL-90-R), was administered to assess various aspects of symptomatology as potential predictor variables.

Multiple regression analyses were conducted to identify predictors of SQOL. Overall, SQOL was low in CFS patients and less favourable than in groups with mental disorders and healthy subjects. Satisfaction was particularly low with life as a whole, leisure activities and financial situation. Whilst SQOL was only moderately correlated with HRQOL, the SCL-90-R score, especially SCL-90-R Depression scale score, was the best predictor of SQOL explaining 35% of the variance. HRQOL and generic SQOL appear distinct despite some overlap.

The findings underline that SQOL is significantly disrupted in CFS patients. Depressive symptoms are statistically the strongest ‘predictor’ of SQOL, although the direction of the relationship is not established. These data suggest that treatment of depression associated with CFS, regardless of causation, could help to improve SQOL in CFS patients.

The placebo response in the treatment of chronic fatigue syndrome: a systematic review and meta-analysis

Abstract:

OBJECTIVE: The placebo response is conventionally asserted to be high in chronic fatigue syndrome (CFS) because of the latter’s subjective nature and obscure pathogenesis, but no systematic review of placebo responses has been undertaken. We report such a study. Patient expectation is known to be important in the placebo response. It is also known that CFS patients attending specialist clinics often have strong physical attributions regarding causation and hence skepticism about psychological or psychiatric interventions. If so, the placebo response in CFS may be influenced by the type of intervention according to its perceived rationale. We aimed to estimate the summary placebo response in clinical trials of CFS and to determine whether intervention type influences the placebo response in CFS.

METHODS: We searched Medline, Embase, Cochrane Library, PsychInfo, and the references of the identified articles, and contacted experts for controlled trials (randomized or nonrandomized) of any intervention on CFS patients reporting the placebo response as a clinical improvement in physical or general outcomes. Data were extracted from the articles and validity assessment conducted by one reviewer and checked by a second. Meta-analysis and metaregression were performed.

RESULTS: The pooled placebo response was 19.6% (95% confidence interval, 15.4-23.7), lower than predicted and lower than in some other medical conditions. The meta-regression revealed that intervention type significantly contributed to the heterogeneity of placebo response (p = .03).

CONCLUSION: In contrast with the conventional wisdom, the placebo response in CFS is low. Psychological-psychiatric interventions were shown to have a lower placebo response, perhaps linked to patient expectations.

A randomized controlled graded exercise trial for chronic fatigue syndrome: outcomes and mechanisms of change

Abstract:

The aim of this study was to investigate the potential mechanisms underlying the efficacy of graded exercise therapy for chronic fatigue syndrome (CFS). Forty-nine CFS patients were randomized to a 12-week graded exercise programme or to standard medical care. At the end of treatment the exercise group rated themselves as significantly more improved and less fatigued than the control group. A decrease in symptom focusing rather than an increase in fitness mediated the treatment effect. Graded exercise appears to be an effective treatment for CFS and it operates in part by reducing the degree to which patients focus on their symptoms.
