Nutritional strategies for treating chronic fatigue syndrome

Abstract:

Despite considerable worldwide efforts, no single etiology has been identified to explain the development of chronic fatigue syndrome (CFS). It is likely that multiple factors promote its development, sometimes with the same factors both causing and being caused by the syndrome.

A detailed review of the literature suggests a number of marginal nutritional deficiencies may have etiologic relevance. These include deficiencies of various B vitamins, vitamin C, magnesium, sodium, zinc, L-tryptophan, L-carnitine, coenzyme Q10, and essential fatty acids. Any of these nutrients could be marginally deficient in CFS patients, a finding that appears to be primarily due to the illness process rather than to inadequate diets. It is likely that marginal deficiencies not only contribute to the clinical manifestations of the syndrome, but also are detrimental to the healing processes.

Therefore, when feasible, objective testing should identify them and their resolution should be assured by repeat testing following initiation of treatment. Moreover, because of the rarity of serious adverse reactions, the difficulty in ruling out marginal deficiencies, and because some of the therapeutic benefits of nutritional supplements appear to be due to pharmacologic effects, it seems rational to consider supplementing CFS patients with the nutrients discussed above, along with a general high-potency vitamin/mineral supplement, at least for a trial period.

Fibromyalgia, chronic fatigue syndrome, and myofascial pain syndrome

Abstract:

Fibromyalgia and widespread pain were common in Gulf War veterans with unexplained illness referred to a rheumatology clinic. Increased tenderness was demonstrated in the postmenstrual phase of the cycle compared with the intermenstrual phase in normally cycling women but not in users of oral contraceptives. Patients with fibromyalgia had high levels of symptoms that have been used to define silicone implant-associated syndrome. Tender points were found to be a common transient finding associated with acute infectious mononucleosis, but fibromyalgia was an unusual long-term outcome. The common association of fibromyalgia with other rheumatic and systemic illnesses was further explored. A preliminary study revealed a possible linkage of fibromyalgia to the HLA region. Patients with fibromyalgia were found to have an impaired ability to activate the hypothalamic pituitary portion of the hypothalamic pituitary adrenal axis as well as the sympathoadrenal system, leading to reduced corticotropin and epinephrine response to hypoglycemia. Much interest has been expressed in the literature on the possible role of autonomic dysfunction in the development or exacerbation of fatigue and other symptoms in chronic fatigue syndrome. Mycoplasma genus and mycoplasma fermentans were detected by polymerase chain reaction in patients with chronic fatigue syndrome. It was reported that myofascial temporomandibular disorder does not run in families. No major therapeutic trials in fibromyalgia, chronic fatigue syndrome, or myofascial pain syndrome were reported over the past year. The effectiveness of cognitive behavioral therapy and behavior therapy for chronic pain in adults was emphasized. A favorable outcome of fibromyalgia and chronic fatigue syndrome in children and adolescents was reported.

Chronic fatigue syndrome

Definition: Chronic fatigue syndrome is characterised by severe, disabling fatigue and other symptoms, including musculoskeletal pain, sleep disturbance, impaired concentration, and headaches. Two widely used definitions of chronic fatigue syndrome (from the US Centers for Disease Control and Prevention 1 and from Oxford 2—see table) were developed as operational criteria for research. There are two important differences between these definitions. The British criteria insist on the presence of mental fatigue; the American criteria include a requirement for several physical symptoms, reflecting the belief that chronic fatigue syndrome has an underlying immunological or infective pathology.

Incidence/prevalence: Community and primary care based studies have reported the prevalence of chronic fatigue syndrome to be 0.2-2.6%, depending on the criteria used.3 4 Systematic population surveys have found similar rates of the syndrome in people of different socioeconomic status, and in all ethnic groups.4 5 Female sex is the only demographic risk factor (relative risk 1.3 to 1.7 depending on diagnostic criteria used).6

Aetiology: The cause of chronic fatigue syndrome is poorly understood.

Prognosis: Studies of prognosis in chronic fatigue syndrome have focused on people attending specialist clinics, who are likely to have had the condition for longer and to have a poorer outlook. Children with the syndrome seem to have a notably better outcome: 54-94% of children show definite improvement (after up to six years’ follow up); 20-50% of adults show some improvement in the medium term and only 6% return to premorbid levels of functioning.7 Despite the considerable burden of morbidity associated with chronic fatigue syndrome, there is no evidence of increased mortality. Outcome is influenced by the presence of psychiatric disorders and beliefs about causation and treatment.7

Aims: To reduce levels of fatigue and associated symptoms; to increase levels of activity; to improve quality of life.

Outcomes: Severity of symptoms; effects on physical function and quality of life measured in several different ways by: the medical outcomes survey short form general health survey (SF-36), a rating scale measuring limitation of physical functioning caused by ill health 8; the Karnofsky scale, a modified questionnaire originally developed for the rating of quality of life in people undergoing chemotherapy for malignancy 9; the Beck depression inventory 10; the sickness impact profile, a measure of the influence of symptoms on social and physical functioning 11; and self reported severity of symptoms and levels of activity.

Chronic fatigue syndrome

Abstract:

The chronic fatigue syndrome is an illness of unknown etiology characterized by severe fatigue, myalgias, lymphadenopathy, arthralgias, chills, fevers, and postexertional malaise. Recognizing chronic fatigue syndrome is primarily a method of exclusion with no definitive diagnostic test or physical findings. As research continues to delve into the many possible etiologic agents for chronic fatigue syndrome–infectious, immunologic, neurologic, or psychiatric alone or in combination–the answer remains elusive. What is known is that chronic fatigue syndrome is a heterogeneous disorder very possibly involving an interaction of biological systems. Therefore, chronic fatigue syndrome may describe a large subset of patients, each exhibiting unique symptoms and serologic profiles dependent on the nature of the onset of illness and the genetic profile of individual patients.

Chronic fatigue syndrome: new insights and old ignorance

Abstract:

Chronic fatigue syndrome (CFS) is a condition characterized by impairment of neurocognitive functions and quality of sleep and of somatic symptoms such as recurrent sore throat, muscle aches, arthralgias, headache, and postexertional malaise. A majority of patients describe an infectious onset but the link between infections and CFS remains uncertain. Findings show an activation of the immune system, abberations in several hypothalamic-pituitary axes and involvement of other parts of the central nervous system. The origin is bound to be complex and it may well be that the solution will come together with a more generally altered view about mind-body dualism, and the concept of illness and disease.

Toward a model of social course in chronic illness: the example of chronic fatigue syndrome

Abstract:

Retrospective, narrative accounts of illness experience in chronic fatigue syndrome provide the empirical basis for a preliminary conceptual model of social course in chronic illness. Qualities of distress interact with culturally specific expectations for social life and personal conduct to trigger microsocial processes of marginalization: role constriction, delegitimation, impoverishment, and social isolation.

Marginalizing processes are opposed by acts of resistance initiated by ill individuals and directed toward integration in social worlds. Social distance from the perceived centers of CFS sufferers’ interpersonal worlds expands and contracts with the changing predominance of marginalizing and resisting influences over time. Social course thus consists of successive, bi-directional movements along a ‘continuum of marginality’ by persons living lives with chronic illness.

Review of juvenile primary fibromyalgia and chronic fatigue syndrome

Abstract:

This article reviews the current literature on childhood fibromyalgia and chronic fatigue syndrome. In doing so, it questions assumptions about the presumed nature of the disorders-that they are distinct from each other and are duplicates of their adult counterparts. It also attempts to synthesize the available data to reach some preliminary judgments about these disorders: that fibromyalgia and chronic fatigue syndrome may be related in children and may not be duplicates of the adult disorders; that psychological and psychosocial factors are unlikely contributors to the etiology of these disorders; and that the evidence is increasingly pointing to a role for genetic factors in their etiology. A discussion of the research into treatments for childhood fibromyalgia and chronic fatigue syndrome highlights the lack of well-designed, controlled studies. Finally, directions for future research are offered where results of the current literature are unclear.

The effects on siblings in families with a child with chronic fatigue syndrome

Abstract:

Paediatric CFS/ME is a stressor, which affects not only the sufferer but also the whole family. The sibling bond exerts a great influence on all the children in the family. Healthy siblings are often overlooked as attention is focused on the child with CFS/ME or other chronic illness. Individual children react in different ways to serious illness in another sibling by adopting a variety of coping mechanisms. There is a need for health and education professionals to consider the whole family when caring for and working with a child with CFS/ME.

Chronic fatigue syndrome does exist. Changes of biological parameters are measurable

Abstract:

Chronic fatigue syndrome is a debilitating condition characterised by neurocognitive and somatic symptoms. Although many patients report an infectious onset, there is no unequivocal evidence to support this. The immune system is activated, and the hypothalamic-pituitary-adrenal axis is involved. The aetiology is complex, and its understanding may require modification of our views on ill-health and disease.

Use of formal and informal care among people with prolonged fatigue: a review of the literature

Abstract:

Prolonged fatigue is a common symptom in the community and a common complaint in GPs’ surgeries. The current consensus is that prolonged fatigue is most appropriately managed within primary care but that quality of care is patchy. Diagnosis is difficult and there is no conclusive evidence about effective treatment. This can lead to confusion and controversy among lay people and health professionals alike. Although the value of a positive doctor-patient relationship is emphasized, general practice consultations are frequently experienced as difficult by both parties. Moreover, little is known about how people access other sources of care and information about prolonged fatigue, such as alternative medicine, self-help groups, lay others, and self care, in conjunction with or as an alternative to care from health professionals. This paper reviews the literature on the nature and extent of the problem prolonged fatigue represents for primary care, and on the use of formal and informal care for prolonged fatigue.
