Chronic fatigue syndrome: a joint paediatric-psychiatric approach

Comment on: Chronic fatigue syndrome: a joint paediatric-psychiatric approach. [Arch Dis Child. 1992]

 

SIR,-While agreeing that physical, psychological, and social factors must all be taken into account in the management of this complex and controversial syndrome I would disagree with Dr Margaret Vereker’s statement that no organic pathology can be detected to account for any of the symptoms. This conclusion has been made without reference to a number of research papers describing persisting viral infection, neuromuscular abnormalities in both structure and function, and immune system dysfunction.

Gow et al using polymerase chain reaction techniques, have been able to demonstrate the presence of enteroviral genome in muscle biopsies from a significant number of patients (53%) compared with controls (15%). None of the healthy control group in this study had evidence of viral particles in their muscle, this was only found in those with colonic or breast malignancies. Precisely what cytopathological effect this intracellular virus is having within muscle remains open to debate. However, Behan et al have published electron microscopic evidence of structural damage to the muscle mitochondria along with type II fibre atrophy; this is a finding which is not normally considered to be consistent with simple disuse.

Therapy of chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome (CFS) is characterized by unexplained, debilitating fatigue or easy fatigability lasting longer than six months. While a number of clinical trials have been performed in CFS patients, there is currently no established therapy for CFS. Treatment with acyclovir of CFS patients is ineffective. Intravenous immunoglobulin therapy appears to be effective, though the results are controversial. Antidepressants might help the associated depression and anxiety but not other symptoms. Trials with magnesium have improved the well-being of patients. Restoration of NK activity by biological response modifiers, such as sizofirann, resulted in restoration of NK cell activity and recovery from CFS. Taken together, immunological abnormalities may be involved in CFS, and its restoration may produce clinical benefit in CFS.

Chronic fatigue syndrome–51 cases in the Jikei University School of Medicine

Abstract:

Between April 1991 and August 1992, we diagnosed 51 cases of CFS who met definition of CFS designated by CDC, 1988. They are 41 female and 11 male, and 78% are women. At first visit, their ages are ranged from 16 to 64 years old, and approximately 45% is 20 to 30 years old.

In periods of illness from onset, 39.2% of the patients are in period of 6 month to 1 year, 19.6% within 2 years, and 15.6% within 3 years, respectively. The sufferer who have symptoms of CFS over 10 years long are in 6 cases.

Most of patients have already been examined by many other clinics and hospitals. They have been told as no abnormal medical condition, or often as neurosis, depressive state and autonomous imbalance etc.

Interesting things are trigger of CFS. 77.5% of patients have onset of flu-like symptom, including 5 cases of acute infectious mononucleosis. In many female patients, symptoms of CFS begun after hard work in addition to psychological factors. Specific laboratory results are not shown in CBC, urinalysis, biochemical studies and inflammatory markers. 6 cases have positive Rheumatoid factor and positive ANF are shown in 16 cases (31.3%).

Specific patterns of anti EBV antibodies are not shown. Lymphocyte subsets used by monoclonal antibodies are not specific. At the present, prognosis is good and 56.8% of CFS patients are generally improved. For severe cases, NSAID, Sulpiride, Amitryptiline and minor tranquilizer are used.

Overview of our patients with chronic fatigue syndrome (CFS) from the pathoetiological aspects

Abstract:

We interviewed 285 patients who visited our department claiming with a complaint of chronic fatigue syndrome (CFS) and subsequently diagnosed 55 as having CFS, according to the criteria for CFS of the centers for disease control (CDC). We measured various virus antibody titers, 2-5, adenylate synthetase levels in the serum lymphocyte subset in blood, employing a double staining technique with monoclonal antibodies. In this paper, we pathoetiology of CFS, based on our findings and other researchers’ is discussed.

Neuro-psychiatric aspects of chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome (CFS) is easily differentiated from various neurological organic disorders by conventional clinical examinations. The most important disease for distinguishment from CFS is fibromyalgia syndrome, in which the prominent and cardinal feature is a deprivation of stage 4 slow wave sleep.

Experimentally, the sleep disturbance in controls can induce general myalgia, muscle tender points, severe fatigue and stiffness on awakening. The EEG abnormality is slow alpha wave contaminants on slow wave background, which is identical to EEG of CFS. The results clearly imply that CFS is not a hysterical or psychogenic disease, and that fibromyalgia may be a central fundamental of CFS.

Fibromyalgia, however, has distinct features such as no antecedent inflammatory process and no endemics. Therefore, the syndrome has features distinct from, in addition to common features to CFS. It is also very difficult to distinguish CFS from depression. The above-mentioned features can be observed in depression. Now, study of brain blood flow or metabolism by PET or SPECT can be a possible tool for establishment of the CFS identity.

Chronic fatigue immune dysfunction syndrome

Abstract:

Chronic fatigue syndrome (CFS) is characterized by unexplained, debilitating fatigue or easy fatigability lasting longer than six months. While a viral basis of infection is proposed to be the cause of CFS, other viral infections do not generally persist after several weeks.

Immunological disorders, including abnormal functions and distributions of T lymphocytes, B lymphocytes, natural killer (NK) cells, and monocyte/macrophages, are described in CFS. NK cells are known to play an important role in host resistance against viral infection as well as in the regulation of the immune systems.

Restoration of NK activity resulted in recovery from CFS. Taken together, immunological abnormalities, especially dysfunction of NK cells, may be involved in CFS.

Chronic fatigue syndrome in school children

Abstract:

Chronic fatigue syndrome (CFS) is characterized by persistent or relapsing debilitating fatigue for at least 6 months without any apparent medical diagnosis that would explain the clinical presentation.

Although, most of the reported patients are over age 30, CFS also affects school children. To better understand CFS, the network of the central nervous-endocrine-immune systems should be considered, and one must be careful to distinct CFS from school absenteeism and other psychosomatic disorders often seen among them.

Diagnostic criteria for chronic fatigue syndrome by the CFS Study Group in Japan

Abstract:

Much interest recently has been given to chronic fatigue syndrome (CFS) in Japan as other countries. The CFS Study Group sponsored by the Ministry of Health and Welfare has been developed since April 1991, A diagnostic criteria for CFS was newly proposed by this group. The criteria is substantially based upon the working case definition, which was made by Holmes and colleagues in 1988. There are some modification from CDC working case definition; the criteria of probable cases of CFS was defined, and postinfectious CFS was also given.

Definition of the chronic fatigue syndrome and its issues

Abstract:

This article reviewed Definition of CFS proposed by CDC 1988. There are several issues in Definition for CFS of CDC. It is presented that other chronic clinical conditions have been satisfactorily excluded, including preexisting psychiatric diseases in (2) of major criteria.

However, fibromyalgia can not be excluded from the fifth symptom of minor criteria, myalgia, and also depression from the ninth symptom.

It is practically difficult to define impairment of average daily activity below 50% of the patient’s premorbid activity level for a period of at least 6 months, as shown in (1) of major criteria, and it is not adapted for a first visit patient.

Definition for CFS of CDC has been discussed on EBV infection, but not written on postviral fatigue syndrome and myalgic encephalomyelitis. Especially whether epidemic type of CFS is present or not was not discussed. Diagnostic criteria of CFS is necessary for clinical practice.

Chronic fatigue syndrome–symptoms, signs, laboratory tests, and prognosis

Abstract:

Chronic fatigue syndrome (CFS) is an undefined clinical problem and is perceived as a complex of multiple symptomatology with an unexplained persistent fatigue. Major symptoms include fatigue lasting for more than 6 months, low-grade fever, moderate lymphadenopathy, muscle and joint pain, and various psychological presentations. Since no specific laboratory tests are available, clinical diagnosis demands that known causes of chronic fatigue should be excluded. The pathogenesis is at present unknown, but it is suspected that CFS is a physical and psychological condition associated with some unrecognized infectious agent. Further study is needed to clarify the precise pathophysiology of this newly recognized entity.
