Correlates of somatic causal attributions in primary care patients with fatigue

Abstract:

Researchers in the field of chronic fatigue in tertiary care found that patients’ somatic (e.g. viral) explanations for their condition may lead to chronicity of symptoms. We studied the influence of a somatic attributional bias on outcome and reported symptoms in primary care patients with fatigue.

We compared fatigue scores on a specific scale, and number of presented symptoms, in two groups of primary care patients with ‘functional’ fatigue: 75 with a high score on the somatic subscale of the Fatigue Attribution Scale (S-FAS), and 95 with a low score on the S-FAS. At the index visit, patients with low and high scores on the S-FAS were not different for age, sex, fatigue scores, and levels of depressive symptoms.

Patients with high scores on the S-FAS presented significantly more somatic and psychological symptoms-a total of 36 symptoms for 24 patients (25.3%) in the low-score group, and a total of 52 symptoms for 31 patients (41.3%) in the high-score group.

Forty-two days later, at the follow-up visit, the fatigue scores were similar in both groups. In primary care patients with fatigue not due to somatic illness or major depression, the tendency to attribute fatigue to somatic causes is not associated with a worse outcome, but with a higher number of reported symptoms.

Psychobehavioral and immunological characteristics of adult people with chronic fatigue and patients with chronic fatigue syndrome

Abstract:

The psychobehavioral responses and cellular immune function were investigated in healthy people (control, N = 21), adult people with chronic fatigue (fatigue-non-CFS group, N = 24), and patients with chronic fatigue syndrome (CFS, N = 10).

Based on psychobehavioral responses, the fatigue-non-CFS group had low general activity levels (p < .05) and slightly depressive tendencies (p < .01) compared with the control. They had many life event stresses (p < .05) and sleep disturbances (p < .01), and they could not cope appropriately with stresses.

The fatigue-non-CFS group also showed significantly lower natural killer (NK) cell activity (p < .01) and decreased numbers of CD16+ and CD56+ cells (p < .05). Compared with the fatigue-non-CFS group, patients with CFS had higher degrees of physical fatigue (p < .01) and more life event stresses (p < .05).

They had lower general activity levels and social introversion. They were also in a depressive state. NK cell activity and the numbers of CD16+ and CD56+ cells were significantly reduced in patients with CFS (p < .01).

These findings suggest that adult people with chronic fatigue may be in an intermediate state between the healthy control and patients with CFS in terms of psychobehavioral responses and low NK cell activity. We observed three cases in such an intermediate state in whom CFS subsequently developed.

Research about fatigue in France over the past 20 years

Abstract:

The author reported the works of the “Fatigue Studies Group” founded 20 years ago to explore the different dimensions of “fatigue” complaint. The emphasis is placed on the asthenic syndromes evaluation instrument created by the group, which takes into account the socio-demographic data of the patient, clinical signs and their severity as well as the potential etiological factors. Its first version (GEF-3) enabled to isolate 4 groups of asthenia (overworking, somatic, psychosomatic and psychic), each of them requesting a specific treatment. An ulterior version (GEF-4) has been elaborated to describe better the psychiatric semeiology. Finally, a simplified version (GEF-10) was used as an evaluation instrument in different therapeutic researches. At the same time, the group continued its researches on the fatigue psychosocial dimensions and its nosographic status, especially in comparison with dysthymic disorders.

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.

Neurasthenia, yesterday and today

Abstract:

Neurasthenia was described and explained in very mechanistic terms, at the end of the 19th century, by G.M. Beard to account for physical and mental exhaustion and for varied somatic troubles imputed to failure of too much solicited nervous resources. This concept was then universally adopted and gave rise to diverse interpretations, among which was the Freud’s one. Later, in Occident, came a deterioration, the diagnostic of neurasthenia giving way to those of anxious or affective disorders. In the same time, at least for ideological and cultural reasons, the concept remained lively in Russia and in Asia. During the last decade the western psychiatry has been led to accept that there are clinical situations focussed on fatigue and fatigability, even if it coined for them new terminologies (post-infectious fatigue, chronic fatigue syndrome, etc.) and while DSMs keep on ignoring neurasthenia, the ICD 10 gives it an important place.

Influence of patients’ expectations on disease

EDITOR,-Michael Loudon continues the debate about the contribution of psychological factors to the development of the chronic fatigue syndrome and the influence of patients’ expectations on the prognosis.

I developed glandular fever over a year ago. For three months earlier this year I had considerable but variable difficulty in getting out of bed in the morning, muscle “woodenness” all over, and wobbly legs in association with a still positive PaulBunnell test. Normal activities have not been a problem for some time now, but I am still struggling to resume sporting activities at something like my previous level.

Why do we seek to make general statements? It is so easy to illustrate the futility of trying to generalise. For example, the teenage son of one of my colleagues on the nursing staff at our hospice died of hepatitis arising from the early stages of glandular fever, despite his transfer to a liver unit. By contrast, I had a normal appetite from the beginning of my illness and no abdominal tenderness. If this lad died of hepatitis and I had no hepatitis at all, does anyone suggest that he did not have a helpful attitude to his illness, while I did to mine? I think not. Why not? Because when we understand and can measure we accept that there is a range of organically based illness.

Surely the reason why there is scepticism about whether the chronic fatigue syndrome has an organic basis is because of the implications for long term absenteeism from work as well as the cost to the country in benefits.

Predictors of chronic “postviral” fatigue

Abstract:

We set out to determine the relation between a general practitioner (GP) diagnosis of viral illness and development of chronic fatigue 6 months later. 618 subjects who attended GPs clinics in London, south, and southwest England and who received a diagnosis of viral illness were followed prospectively and fatigue was assessed by questionnaire after 6 months. At presentation, GPs recorded fatigue in 62.6% of subjects, usually since the onset of symptoms. 502 (81.2%) subjects completed the 6-month questionnaire, of whom 88 (17.5%) met criteria for chronic fatigue and 65 (12.9%) had no reported fatigue before the viral illness.

Compared with a similar group of non-postviral GP attenders, the risk ratio for chronic fatigue in the present cohort was 1.45 (95% CI 1.14-2.04). Infective symptoms did not predict fatigue 6 months later. Psychiatric morbidity, belief in vulnerability to viruses, and attributional style at initial presentation were all associated with self-designated postviral fatigue.

Logistic regression showed that somatic attributional style, less definite diagnosis by the GP, and sick certification were the only significant predictors of chronic fatigue after viral infection when other factors were controlled for. Chronic severe fatigue 6 months after GP-diagnosed viral illness is related to symptom-attributional style and doctor behaviour, rather than to features of the viral illness. Some subjects with apparent postviral fatigue had complained of tiredness before their presentation with a viral illness.

A psychodynamic view of the chronic fatigue syndrome. The role of object relations in etiology and treatment

Abstract:

The chronic fatigue syndrome (CFS) is a constellation of physical and psychological symptoms including incapacitating fatigue associated with a marked reduction in activity. Although the etiology of CFS is unclear, reports in the literature suggest the presence of both physical and psychological dysfunction in this patient population. These findings have led to a debate between those who consider CFS to be primarily organic in origin and those who view CFS as a primary psychiatric disorder characterized by somatic preoccupations.

This debate led the authors to develop a working model for CFS designed to integrate the psychological and physiological findings, based on the hypothesis that early object relations have an etiologic relationship to CFS. This hypothesis then formed the rationale for a psychoanalytic treatment approach which will be described.

There are no published case reports describing psychoanalytic psychotherapy as a primary treatment modality for this patient population. The current paper attempts to fill a void. Two case reports of long-term (> 18 months), intensive (2-3 times per week) psychoanalytic psychotherapy with CFS patients referred by infectious disease specialists at a university teaching hospital will be presented.

The following aspects of the treatment will be highlighted: 1) the unique opportunity afforded by this treatment to view the nature of CFS, namely, the intimate relationship over time of fatigue symptoms to disturbances in object relationships, particularly within the transference; (2) the improvement in symptoms when this relationship is seen and understood by the patient; (3) the importance of the patient-therapist bond as a facilitating medium for clinical improvement; (4) the challenges involved in treating CFS patients with psychotherapy.

Cognitive functioning in chronic fatigue syndrome and depression: a preliminary comparison

Abstract:

This study used a brief battery of neuropsychological measures to examine the performance of patients with chronic fatigue syndrome (CFS) (N = 16) and patients in a major depressive episode (N = 23). The overall neuropsychological performance of the CFS group was not significantly different from depressed patients, and both groups scored within normal limits on most measures. Variability of neuropsychologic performance was in general unrelated to level of depressive symptoms. The results are discussed in terms of the validity of the cognitive criterion for the CFS diagnosis. Subjective complaints of cognitive dysfunction by CFS patients in light of the lack of objective evidence for the same are considered in terms of a somatic vigilance hypothesis.

Psychosocial factors and chronic fatigue syndrome

Abstract:

This study investigated the number and severity of life events, Type A behaviour, coping strategies and social support differences between chronic fatigue and irritable bowel syndrome patients prior to illness and between these groups and healthy controls. Although few differences were found between the groups for life events, a number of interesting results emerged with regard to different aspects of Type A behaviour, various coping strategies and social support. These findings are discussed with respect to existing research in the field.
