Acupuncture in the treatment of post viral fatigue syndrome–a case report

Abstract:

This case report concerns the treatment of post viral fatigue (chronic fatigue syndrome) with electroacupuncture. This condition is particularly difficult to treat whether using conventional or complementary therapy. Whilst the treatment did not cure the patient, it appears to have facilitated her return to work and markedly improved her symptoms. There are few publications on acupuncture treatment of this condition and the approach used here has not been reported previously.

Time course of exercise induced alterations in daily activity in chronic fatigue syndrome

Abstract:

In a previous study we demonstrated that while people with CFS had lower daily activity levels than control subjects, they were able to increase daily activity via a daily walking program. We reanalyzed our data to determine the time course of activity changes during the walking program. Daily activity assessed via an accelometer worn at the hip was divided into sleep, active, and walking periods. Over the first 4-10 days of walking the subjects with CFS were able to reach the prescribed activity goals each day. After this time, walking and total activity counts decreased. Sedentary controls subjects were able to maintain their daily walking and total activity goals throughout the 4 weeks. Unlike our previous interpretation of the data, we feel this new analysis suggests that CFS patients may develop exercise intolerance as demonstrated by reduced total activity after 4-10 days. The inability to sustain target activity levels, associated with pronounced worsening of symptomology, suggests the subjects with CFS had reached their activity limit.

The role of enterovirus in chronic fatigue syndrome

Abstract:

Two and a half decades after coining of the term chronic fatigue syndrome (CFS), the diagnosis of this illness is still symptom based and the aetiology remains elusive. Enteroviruses are well known causes of acute respiratory and gastrointestinal infections, with tropism for the central nervous system, muscles, and heart.

Initial reports of chronic enteroviral infections causing debilitating symptoms in patients with CFS were met with skeptism, and had been largely forgotten for the past decade. Observations from in vitro experiments and from animal models clearly established a state of chronic persistence through the formation of double stranded RNA, similar to findings reported in muscle biopsies of patients with CFS.

Recent evidence not only confirmed the earlier studies, but also clarified the pathogenic role of viral RNA through antiviral treatment. This review summarises the available experimental and clinical evidence that supports the role of enterovirus in chronic fatigue syndrome.

The prevalence of self-reported chronic fatigue in a U.S. twin registry

Abstract:

OBJECTIVE: To investigate the prevalence and correlates of various definitions of self-reported lifetime fatiguing illness in a U.S. twin registry.

METHODS: Data from 4591 female and male twins from the population-based Mid-Atlantic Twin Registry were available for this study. Variables representing different definitions of lifetime fatiguing illness and personal characteristics were obtained through questionnaires. Odds ratios and 95% confidence intervals were calculated as measures of association between fatigue and gender. Kaplan-Meier curves were produced to examine the age at onset for lifetime fatiguing illnesses.

RESULTS: Prevalences for different definitions of self-reported lifetime fatigue ranged from 36.7% for any fatigue to 2.7% for chronic fatigue syndrome-like illness. Females were two to three times more likely to report fatigue than males. Gender differences increased as fatigue definitions grew more restrictive. Ages at onset of chronic fatiguing illness were significantly earlier and the number of ancillary symptoms was greater for females than males. People with lifetime fatigue had significantly more compromised functional status than people without lifetime fatigue.

CONCLUSION: The prevalence of self-reported lifetime fatiguing illness varied widely depending upon how it was defined. Given the debilitating consequences of fatiguing illnesses, the reasons for the female predominance and the earlier onset in women should receive increased research priority.

Practitioner review: chronic fatigue syndrome in childhood

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) is being increasingly recognized in children and adolescents. Yet comparatively little attention has been given in the literature to management.

METHODS: Description of the main features of the disorder, precipitating and maintaining factors and diagnostic assessment. Outline of different views on the nature and treatment of CFS in childhood. Description of a rehabilitation program based on cognitive behavior therapy and graded activity.

RESULTS: Using adult research criteria, CFS can be diagnosed in children and adolescents. In its severe form it is often triggered by infectious illness episodes. It is commonly associated with mood disorders in the child and with mental distress and high levels of emotional involvement in parents. A number of patient support groups hold the view that CFS is a medical disorder, contest a psychiatric contribution and advocate ‘pacing’ as an approach to rehabilitation which includes avoiding activities. To date there is no empirical evidence for the efficacy of this approach. Research in adults, open and clinical reports in children support the use of graded activity and family cognitive behavior therapy. The main aim is to enable children, with the help of their family, to carry out their own rehabilitation with some support and guidance from a health professional. Engaging the child and family in treatment and forming a therapeutic alliance is a continual process and a crucial aspect of management, as many families view the condition as a medical disorder and are initially ambivalent towards this approach.

CONCLUSIONS: There is controversy about the nature and management of CFS in childhood but a rehabilitation program based on family cognitive behavior therapy can be implemented and seems to hold most promise in the management of children with CFS. Family engagement is a crucial aspect of management.

Chronic fatigue syndrome: an overview

Medically unexplained symptoms (MUS) – those lacking identifiable underlying physical disease – are common in all levels of the health care system, and can be associated with severe disability and distress to patients and high cost to health services. Common MUS include pain (including back, chest, abdominal pain, and headache), fatigue, dizziness and ENT (Ear, Nose and Throat) symptoms. Similarly, functional somatic syndromes refer to groups of symptoms lacking disease-specific, demonstrable abnormalities of structure, and are usually defined by specialty or organ system.1 They include irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, multiple chemical sensitivity, chronic pelvic pain, temporomandibular joint dysfunction and more recently Gulf War syndrome. These conditions overlap in their symptoms, aetiology and treatment; prompting some to point out that the similarities outweigh differences between them and that there is utility in considering them collectively rather than separately.2

Impact of a maximal exercise test on symptoms and activity in chronic fatigue syndrome

Abstract:

OBJECTIVE: This study examined the effects of exercise on symptoms and activity in chronic fatigue syndrome (CFS).

METHODS: Twenty CFS patients and 20 neighborhood controls performed an incremental exercise test until exhaustion. Fatigue, muscle pain, minutes spent resting, and the level of physical activity were assessed with a self-observation list. Physical activity was assessed with an actometer as well. Data were obtained 3 days before the maximal exercise test (MET) up to 5 days thereafter.

RESULTS: For CFS patients, daily observed fatigue was increased up to 2 days after the exercise test. For controls, self-observed fatigue returned to baseline after 2 h. Both CFS patients and controls spent more minutes resting on the day before and on the day after the MET. For CFS patients, self-observed minutes resting increased on the day of the exercise test. For neither group, a decrease of actometer recorded or self-observed physical activity after exercise was found.

CONCLUSION: Fatigue in CFS patients increased after exercise, but the level of actual physical activity remained unchanged.

Children and adolescents with Chronic Fatigue Syndrome in non-specialist settings: beliefs, functional impairment and psychiatric disturbance

Abstract:

BACKGROUND: Adolescents with Chronic Fatigue Syndrome (CFS) seen in specialist centres have substantial psychological and functional impairment. Beliefs about activity levels may be important in the development of CFS.

METHOD: The aim was to investigate psychological and functional impairment, and beliefs in children and adolescents with CFS recruited from non-specialist services. A total of 30 such individuals participated, and 30 young people with Inflammatory Bowel Disease (IBD) formed the comparison group.

RESULTS: Emotional symptoms and disorder were high in both groups. In all, 50% of those with CFS and 30% with IBD reached the threshold for emotional disorder according to the Strengths and Difficulties Questionnaire (SDQ) parent report, although this difference did not reach statistical significance. Participants with CFS scored statistically significantly higher on measures of functional impairment, including school non-attendance, compared to those with IBD. According to questionnaire responses, those with CFS were statistically significantly more likely to favour rest rather than exercise compared to those with IBD. Comparison of parental beliefs did not show such a difference.

CONCLUSIONS: These young people with CFS were at high risk of psychiatric disorder. They were substantially disabled when compared to individuals with a known chronic illness. Also, as a group, they were characterised by a preference for rest rather than exercise.

37-Kilodalton/83-kilodalton RNase L isoform ratio in peripheral blood mononuclear cells: analytical performance and relevance for chronic fatigue syndrome

Comment on: RNase L levels in peripheral blood mononuclear cells: 37-kilodalton/83-kilodalton isoform ratio is a potential test for chronic fatigue syndrome.[Clin Diagn Lab Immunol. 2003]

 

A French group has reported results (5) supporting the use of the RNase L 37-kDa/83-kDa ratio (37/83 R) in peripheral blood mononuclear cells (PBMC) as a diagnostic test for chronic fatigue syndrome (CFS). More recently (6), the same group cautioned about the diagnostic value of the 37/83 R, based on a small patient follow-up study which was likely to indicate analytical variability among duplicate assays, lack of reproducibility over time, and a weak correlation with the multidimensional fatigue inventory (MFI) score. Because of our long-term experience with this assay, we would like to offer some comments.

First, we tested the analytical performance of the 37/83 R assay according to CLSI (formerly NCCLS) procedure EP5-A (4), with control samples at three different levels made of extracts of the monocytic U937 cell line spiked with various concentrations of recombinant RNase L. The guideline protocol involves assaying the samples in duplicate twice daily over a total period of 20 days. The results summarized in Table Table11 indicate that both within- and between-run variation does not exceed 13%. In another series of experiments, we assayed eight patient samples in duplicate (average 37/83 R ranging from 0.5 to 245). Although in accordance with the NCCLS protocol results, the variation did not exceed 12% for samples with 37/83 R levels up to 20, and it rose significantly to 30% and more for samples with 37/83 R levels above 20. This should be expected, because beyond this level, more than 70% of the 83-kDa isoform is cleaved, and consequently, the faint 83-kDa band is difficult to scan with accuracy. Thus, in our opinion, the lower level of correlation between the duplicate assay results observed with the CFS group versus those with the controls (6) reflects the prevalence of high 37/83 R levels in the CFS group rather than a low test reproducibility as claimed by these authors. This is further supported by the good correlation found for the control group (r = 0.95). During validation, the lowest detectable ratio measured with a sample containing the 83-kDa isoform only was estimated (3 independent experiments with 26 replicates each) to be 0.13 ± 0.06 (average ± three standard deviations). Thus, the clinical cutoff ratio of 0.4 found by the authors (5, 6) to best discriminate CFS patients from controls falls within the measurable range.
