Chronic fatigue syndrome: current perspectives on evaluation and management

Abstract:

OBJECTIVE: To describe clinical and laboratory guidelines for assessment and management of patients presenting with chronic fatigue syndrome(CFS).

DATA SOURCES: Relevant international consensus diagnostic criteria and research literature on the epidemiology, pathophysiology, concurrent medical and psychological disturbance and clinical management of CFS.

CONCLUSIONS: Medical and psychiatric morbidity should be carefully assessed and actively treated, while unnecessary laboratory investigations and extravagant treatment regimens should be avoided. No single infective agent has been demonstrated as the cause of CFS, and immunopathological hypotheses remain speculative. The aetiological role of psychological factors is debated, but they do predict prolonged illness. The rate of spontaneous recovery appears to be high. Effective clinical management requires a multidisciplinary approach, with consideration of the medical, psychological and social factors influencing recovery.

Functional capacity evaluations of persons with chronic fatigue immune dysfunction syndrome

Abstract:

Chronic Fatigue Immune Dysfunction Syndrome (CFIDS) is estimated to affect 2 to 5 million people in the United States. Despite its high incidence, persons with CFIDS have been neglected by the medical community mainly because there is no singular confirming diagnostic test or proven effective treatment.

The CFIDS population is incorrectly stereotyped as upper-middle-class, white, female hypochondriacs; consequently, symptoms often are belittled or ignored. In reality, CFIDS is a severe medical condition that affects women, men, and children of any race and often causes long-term or total disability.

The results of a modified functional capacity evaluation developed by the author and completed on 86 persons with CFIDS between 1988 and 1990 confirm that this population has severe physical and cognitive disabilities that affect their professional, familial, and social lives. The results of these evaluations are used to present a profile of persons with CFIDS that can serve as a basis for understanding this population and for guiding intervention.

The chronically fatigued patient

Abstract:

This article illustrates that the diagnostic evaluation as well as the management of the patient presenting with chronic fatigue can be done in an orderly manner. If a medical illness is the cause of the patient’s fatigue, this is usually evident on initial presentation. A thorough history and complete physical examination, in conjunction with some screening laboratory tests, can rule out most medical causes of fatigue, and any remaining cases declare themselves over the next several visits. If a medical cause is not evident, a further “fishing expedition” is fruitless.

Psychiatric illness, such as depression or generalized anxiety disorder, accounts for another significant proportion of cases of chronic fatigue. As with medical illness, psychiatric illness should be suspected based on history and is not a diagnosis of exclusion. Some patients presenting with chronic fatigue have a history and symptom pattern consistent with the diagnosis of CFS. The cause of this syndrome is controversial and is still unknown. The clinician, however, can offer the patient care in an environment that is respectful of their physical and psychological discomfort and can provide significant symptomatic improvement to the patient.

Lastly, some patients with fatigue do not fit any diagnostic category, including CFS. As with many other common complaints, such as headaches or abdominal pain, although a diagnosis may not be given to the patient, the clinician can do a lot to reassure the patient and assist the patient in living with his or her symptoms. As Solberg eloquently wrote: “[E]valuation of the fatigued patient requires all of a physician’s best attributes–a broad view of disease, psychosocial sensitivity, and a good ongoing relationship with the patient.”
