The report of the Chief Medical Officer’s CFS/ME working group: what does it say and will it help?

Abstract:

Chronic fatigue syndrome (CFS) sometimes known as myalgic encephalomyelitis or encephalopathy (ME) has long been a controversial topic. This year has seen the publication of a report from an independent working party set up by the UK Chief Medical Officer (CMO) to make recommendations for the management of the condition. The report makes a number of general recommendations about the provision of appropriate care and services. The more controversial issues of what to call the illness, the nature of the illness and what treatment should be recommended are all addressed, but in the form of compromise rather than resolution. To the extent that this report is a step towards highlighting the needs not only of patients with CFS but the larger group of patients with symptom-defined conditions, it is to be welcomed. As a guide to management it raises as many questions as it answers. Much remains to be resolved before guidance that is both evidence based and acceptable to all parties is achieved.

Interpretation of symptoms in chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome (CFS) is an illness characterised by fatigue and other symptoms. Both psychological and biological aetiological factors have been proposed, but the disorder is of uncertain origin. The aetiology of the symptoms is therefore ambiguous. It has been suggested (a) that patients with CFS tend to interpret their symptoms as indicating physical illness and (b) they tend not to interpret these symptoms in terms of negative emotion.

In order to test these hypotheses we developed a self-report questionnaire to assess the interpretation of symptoms in patients with CFS. It was administered to patients with CFS, patients with depression, patients with multiple sclerosis (MS), and normal controls. Preliminary results suggest that the measure has acceptable psychometric properties.

Patients with CFS were more likely than either depressed patients or normal controls to interpret symptoms (characteristic of CFS) in terms of physical illness, but did not differ in this from the MS patients. When compared with all three other groups (including the MS patients), the patients with CFS were least likely to interpret symptoms in terms of negative emotional states. The theoretical and clinical implications of the findings are discussed.

Health-related quality of life in patients with chronic fatigue syndrome: an international study

Abstract:

OBJECTIVE: Chronic fatigue syndrome (CFS) has been reported worldwide. Our objectives were to determine if patients from different countries have similar profiles of impairments.

METHODS: Health-related quality of life (HRQoL) was assessed in 740 CFS patients in the US, 82 in the UK, and 65 in Germany using the eight subscales of the Short-Form General Health Survey (SF-36). To examine the internal structure, factor analyses were performed.

RESULTS: Overall, there was a remarkable similarity in HRQoL among all CFS patients, regardless of location. Patients scored two to three standard deviations below normal on six subscales and one standard deviation below normal on the other two subscales. Factor analysis suggested a two-factor model where the same six subscales constitute the first factor and the two others the second factor.

CONCLUSION: HRQoL is poor in CFS patients from three countries. This study is a first step towards conducting further comparative cross-cultural and international studies.

Personality dimensions in chronic fatigue syndrome and depression

Abstract:

Chronic fatigue syndrome (CFS) is a poorly understood condition. Possible etiological factors include infectious agents, psychiatric disorders, and personality characteristics. We examined personality dimensions in 30 nondepressed patients with CFS, 20 patients with major depressive disorder (MDD), and 15 healthy controls. On the NEO-FFI, patients with CFS scored significantly lower than healthy controls on the extroversion subscale. On the neuroticism dimension of the Eysenck Personality Questionnaire (EPQ), patients with MDD scored higher than those with CFS, who in turn scored significantly higher than the healthy controls. CFS patients rated themselves as higher on neuroticism and less extroverted when ill than when they were well. Our results suggest that high scores on neuroticism and low scores on extroversion in CFS could be a reaction to chronic illness.

Cognitive behavior therapy for chronic fatigue syndrome: efficacy and implications

Abstract:

Cognitive behavior therapy (CBT) is a form of non-pharmacologic treatment. It is based on a model of chronic fatigue syndrome (CFS) that hypothesizes that certain cognitions and behavior may perpetuate symptoms and disability–that is, act as obstacles to recovery. Treatment emphasizes self-help and aims to help the patient to recover by changing these unhelpful cognitions and behavior.

There is now good evidence from 2 independent randomized clinical trials to support the efficacy of CBT in patients with CFS. The treatment effect is substantial, although few patients are cured. The urgent clinical need is to make this form of treatment available to patients with CFS. One approach is to incorporate the principles of CBT into routine clinical practice. The preliminary evaluation of these simpler forms of CBT are promising, although the results of controlled trials are awaited. At present, intensive individual CBT administered by a skilled therapist remains the treatment of choice for patients with CFS.

Putting the rest cure to rest—again

Go home and rest” is still the advice given to many patients who complain of chronic fatigue. The refrain is echoed in self help books and magazines and adopted by many patients. What are the origins of rest as a treatment, does it work, and what evidence is there on which to base our advice to patients?

Victorian physicians diagnosed them as neurasthenia and routinely prescribed rest. This approach was typified by Silas Weir Mitchell’s “rest cure,” which was so popular as to be described as “the greatest advance of which practical medicine can boast in the last quarter of the century.” Despite such accolades, the popularity of the rest cure was short lived. By the turn of the century the same private clinics that once provided it were changing to more active treatments and to the newer psychotherapies. The years that followed saw the end of the rest cure; Karl Menninger poured scorn on the lack of psychological sophistication shown by its proponents, while Richard Asher drew attention to the “the dangers of going to bed.”

Basal activity of the hypothalamic-pituitary-adrenal axis in patients with the chronic fatigue syndrome (neurasthenia)

Abstract:

BACKGROUND: Impairments in both basal activity and activation of the hypothalamic-pituitary- adrenal axis (HPA) have been reported in chronic fatigue syndrome (CFS; neurasthenia). We sought to replicate these findings and examined basal activity of the HPA in a carefully selected sample of patients with CFS.

METHODS: Basal activity of the HPA was assessed using salivary and urinary cortisol collection over a 24-hour period in 22 (12 male; 10 female) patients meeting criteria for CFS and appropriate controls.

RESULTS: Salivary and urinary cortisol measures did not differ between CFS patients and controls.

CONCLUSIONS: Basal activity of the HPA was not reduced in CFS patients. Reasons for the failure to replicate previous findings are discussed.

Do patients with “pure” chronic fatigue syndrome (neurasthenia) have abnormal sleep?

Abstract:

OBJECTIVE: To determine whether patients with “pure” chronic fatigue syndrome (neurasthenia) have sleep abnormalities which may contribute to subjective measures of daytime fatigue.

METHOD: Sleep characteristics of 20 patients meeting research criteria for chronic fatigue syndrome (CFS) but not depression, anxiety, or sleep disorder were compared with sleep characteristics of 20 healthy subjects matched for age and sex. Measures of sleep included a) subjective interview reports and sleep diaries and b) home-based polysomnography.

RESULTS: Patients with CFS complained of poor quality unrefreshing sleep. They also napped during the day. Polysomnograph data showed no difference in actual nocturnal sleep time between the two groups although patients with CFS spent significantly longer in bed (p < .01), slept less efficiently (p < .03), and spent longer awake after sleep onset (p < .05). The polysomnographs of seven patients with CFS and one healthy subject were regarded as significantly abnormal. Five patients and one healthy subject had difficulty maintaining sleep. One patient had a disorder of both initiating and maintaining sleep and one patient woke early.

CONCLUSIONS: Patients with “pure” CFS complain of unrefreshing sleep but only a minority have a clearly abnormal polysomnograph. The most common abnormality is of long periods spent awake after initial sleep onset. Although sleep abnormalities may play a role in the etiology of CFS, they seem to be unlikely to be an important cause of daytime fatigue in the majority of patients. However, pharmacological and behavioral methods that improve sleep quality may be an important component of a pragmatically based treatment package for patients who do have abnormal sleep.

Increased brain serotonin function in men with chronic fatigue syndrome

Recent neuroendocrine studies suggest that patients with chronic fatigue syndrome may have increased brain serotonin activity.1 2 This could be relevant to the pathophysiology of chronic fatigue syndrome because serotonin pathways have a role in mediating central fatigue.3 Currently, however, the existence of abnormal serotonin neuroendocrine function in patients with chronic fatigue syndrome is controversial because of contradictory findings from samples of heterogeneous patients 4 5 and the use of serotonin probes such as buspirone, which are of doubtful pharmacological specificity.1 We aimed to measure the increase in plasma prolactin after administration of the selective serotonin releasing agent d-fenfluramine in men rigorously diagnosed as having the chronic fatigue syndrome and carefully matched healthy controls.

Cognitive behavior therapy for functional somatic complaints. The example of chronic fatigue syndrome

Abstract:

Somatic complaints such as pain and fatigue that are unexplained by conventional disease are common in medical practice and are referred to as functional, somatoform, or somatization symptoms. Despite frequent chronicity, disability, and high associated medical costs, patients with these complaints are rarely offered either constructive explanations or effective treatment. In this perspective, a cognitive-behavioral approach to the problem is described, using chronic fatigue syndrome as an example. It is concluded that the utility of the cognitive-behavioral theory and the proven effectiveness cognitive behavior therapy provide the basis for a new evidence-based approach to psychosomatics.
