Childhood maltreatment and the response to cognitive behavior therapy for chronic fatigue syndrome

Abstract:

OBJECTIVE: To examine the relationship between a history of childhood maltreatment and the treatment response to cognitive behavior therapy for chronic fatigue syndrome (CFS).

METHODS: A cohort study in a tertiary care clinic with a referred sample of 216 adult patients meeting the Centers for Disease Control and Prevention criteria for CFS, and starting cognitive behavior therapy. Main outcome measures changes between pre- and post therapy in fatigue (Checklist Individual Strength fatigue subscale), disabilities (Sickness Impact Profile total score), physical functioning (short form 36 health survey subscale) and psychological distress (Symptom checklist 90 total score).

RESULTS: At baseline, patients with a history of childhood maltreatment had significantly more limitations and a higher level of psychological distress, but were not more severely fatigued. Change scores on the outcome measures after cognitive behavior therapy did not differ significantly between patients with or without a history of childhood maltreatment, or between the different types of childhood maltreatment. However, patients with a history of childhood maltreatment still experienced more limitations and a higher level of psychological distress after CBT.

CONCLUSIONS: A history of childhood maltreatment was not related to the treatment response of cognitive behavior therapy for CFS. In patients with a history of childhood maltreatment CFS symptoms can be treated with CBT just as well as those without.

Up-regulation of TGF-β1 mRNA expression in peripheral blood mononuclear cells of patients with chronic fatigue syndrome

Abstract:

BACKGROUND/PURPOSE: It has been shown that the abnormality in immune cells in chronic fatigue syndrome (CFS) patients is closely associated with the participation of TGF-β. In order to study the relationship between TGF-β1 and CFS, we investigated the mRNA levels of TGF-β1 in peripheral blood mononuclear cells (PBMCs) in patients with CFS.

METHODS: Fluorescent quantitative real time reverse-transcription polymerase chain reaction (FQ-RT-PCR) was performed to test TGF-β1 mRNA expression in PBMCs in 63 cases of CFS, 50 cases of disease controls, and 50 cases of healthy controls.

RESULTS: The mean value of TGF-β1 mRNA expression in CFS patients was ΔΔCt=1.17±0.58, which was significantly higher than the disease controls (ΔΔCt=0.07±1.08, df=111, p < 0.01) and the healthy controls (ΔΔCt=0.00±1.63, df=111, p < 0.01). No significant difference was detected between disease and healthy controls (p > 0.05).

CONCLUSION: The expression of TGF-β1 in PBMCs is significantly elevated in patients with CFS. It might be correlated to the pathogenesis of the disease.

Fibromyalgia and chronic fatigue syndrome in children

Abstract:

BACKGROUND: Fibromyalgia (FM) is characterized by widespread persistent pain and the presence of multiple discrete tender points. Chronic fatigue syndrome (CFS) is a syndrome characterized by debilitating fatigue associated with a variable number of non-specific complaints. Because neither condition had necessarily been recognized in children until recently, those patients have been treated as having school refusal without being diagnosed as having either syndrome. There is a considerable overlap of clinical symptoms between these two syndromes. It is therefore controversial as to whether these syndromes have the same pathogenesis or not. The aim of the present study was to clarify the relationship between these syndromes in children.

METHODS: Fifteen patients with FM and 21 patients with CFS were investigated both clinically and immunologically. Immunological assessments included thorough analysis of autoantibodies using several techniques.

RESULTS: Anti-nuclear antibody titers were higher and the prevalence of anti-Sa antibody was far more frequent in CFS patients than in FM patients.

CONCLUSION: CFS and FM are different from each other at least in childhood, from an immunological aspect, although some patients could have both conditions.

Chronic fatigue syndrome: acute infection and history of physical activity affect resting levels and response to exercise of plasma oxidant/antioxidant status and heat shock proteins

Abstract:

OBJECTIVES: A history of high-level physical activity and/or acute infection might constitute stress factors affecting the plasma oxidant-antioxidant status and levels of heat shock proteins (HSPs) in patients with chronic fatigue syndrome (CFS).

DESIGN: This case-control study compared data from 43 CFS patients to results from a matched control group of 23 healthy sedentary subjects.

SETTING AND SUBJECTS: Five patients had no relevant previous history (group I). Eighteen had practised high-level sport (group II), and severe acute infection had been diagnosed in nine patients (group III). A combination of sport practice and infection was noted in 11 patients (group IV).

INTERVENTIONS: After examination at rest, all subjects performed a maximal cycling exercise test. Plasma levels of two markers of oxidative stress [thiobarbituric acid reactive substances (TBARS) and reduced ascorbic acid (RAA)] and both HSP27 and HSP70 were measured.

RESULTS: At rest, compared with the control group, the TBARS level was higher in groups II, III and IV patients, and the RAA level was lower in groups III and IV. In addition, HSP70 levels were significantly lower in all CFS groups, compared with controls, but negative correlations were found between resting HSP27 and HSP70 levels and the history of physical activity. After exercise, the peak level of TBARS significantly increased in groups II, III and IV, and the variations in HSP27 and HSP70 were attenuated or suppressed, with the greatest effects in groups III and IV.

CONCLUSION: The presence of stress factors in the history of CFS patients is associated with severe oxidative stress and the suppression of protective HSP27 and HSP70 responses to exercise.

Genetics and Gene Expression Involving Stress and Distress Pathways in Fibromyalgia with and without Comorbid Chronic Fatigue Syndrome

Abstract:

In complex multisymptom disorders like fibromyalgia syndrome (FMS) and chronic fatigue syndrome (CFS) that are defined primarily by subjective symptoms, genetic and gene expression profiles can provide very useful objective information.

This paper summarizes research on genes that may be linked to increased susceptibility in developing and maintaining these disorders, and research on resting and stressor-evoked changes in leukocyte gene expression, highlighting physiological pathways linked to stress and distress. These include the adrenergic nervous system, the hypothalamic-pituitary-adrenal axis and serotonergic pathways, and exercise responsive metabolite-detecting ion channels.

The findings to date provide some support for both inherited susceptibility and/or physiological dysregulation in all three systems, particularly for catechol-O-methyl transferase (COMT) genes, the glucocorticoid and the related mineralocorticoid receptors (NR3C1, NR3C2), and the purinergic 2X4 (P2X4) ion channel involved as a sensory receptor for muscle pain and fatigue and also in upregulation of spinal microglia in chronic pain models. Methodological concerns for future research, including potential influences of comorbid clinical depression and antidepressants and other medications, on gene expression are also addressed.

Factor analysis of the Beck Depression Inventory-II with patients with chronic fatigue syndrome

Abstract:

This study examined the properties of the Beck Depression Inventory-II (BDI-II) in a sample of 111 patients with chronic fatigue syndrome (CFS). Exploratory factor analysis identified two factors. The mean score for the Somatic-Affective factor was significantly higher than the Cognitive factor. Convergent and discriminant validity were assessed for BDI-II total score, the two factor scores, and the BDI for Primary Care (BDI-PC). The BDI-PC and Cognitive factor demonstrated superior validity. Results suggest patients endorse BDI-II somatic items that overlap with CFS symptoms at a high rate. Factor scores should be evaluated separately, or the BDI-PC should be utilized with this population.

The occupational and quality of life consequences of chronic fatigue syndrome/myalgic encephalomyelitis in young people

Abstract:

INTRODUCTION: Chronic fatigue syndrome, termed myalgic encephalomyelitis in the United Kingdom (CFS/ME), is a debilitating condition involving severe exhaustion, cognitive difficulties, educational and vocational losses, and disruption of social activities and relationships. CFS/ME may affect volition (that is, value, interest and sense of competence).

PURPOSE: To test Model of Human Occupation (MOHO) concepts by comparing young people with and without CFS/ME in terms of occupational participation, volition and health-related quality of life during infection and over time.

METHOD: Three hundred and one people (12-18 years old) diagnosed with glandular fever were evaluated at the time of acute infection (baseline). Six months following diagnosis, 39 of them met the criteria for CFS/ME. A further 39 who recovered were randomly selected and matched to CFS/ME participants. Both groups were re-evaluated at 12 months and 24 months. The Occupational Self Assessment and the Child General Health Questionnaire were used to compare occupational participation.

RESULTS: Those with CFS/ME reported lower levels of perceived competency, more difficulties with physical functioning and poorer general health status than those who recovered.

CONCLUSION: Those with CFS/ME report lower perceived competency, and compromises in physical functioning, school performance, social activities, emotional functioning and general health. This supports the MOHO assertion that impairments affect volition and quality of life.

Kynurenine pathway Hypothesis: The nature of the chronic Fatigue syndrome (cFs) Revisited

Moderate physicians consider CFS to be missed diagnoses of uncommon illnesses with atypical features. Hartnup (heterozygotes), Lyme and Whipples—like diseases are examples of conditions which fit these clinical ambiguities. The detractors claim it is non-existent. The protractors complain CFS is excluded from standard medical texts. A broad overview of medical literature and support group newsletters, render these opposing views substantially incorrect.

The patient presents with a confounding array of neurological, mental, gastrointestinal, musculoskeletal and perhaps dermatological and visual signs and symptoms. Episodic night sweats can also be reported. Lack of energy, concentration and mobility, limit lifestyle. These symptom constellations evolve and fluctuate in a seemingly random order and can become entrenched. Alcohol intake, protracted steroid therapy and overt or latent infections usually aggravate the course of CFS.

What stops children with a chronic illness accessing health care: a mixed methods study in children with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME)

Abstract:

BACKGROUND: Paediatric Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is relatively common and disabling with a mean time out of school of more than one academic year. NICE guidelines recommend referral to specialist services immediately if severely affected, within 3 months if moderately affected and within 6 months if mildly affected. However, the median time-to-assessment by a specialist service in the UK is 18 months. This study used a mixed-methods approach to examine factors associated with time taken to access specialist services.

METHODS: Time-to-assessment was analysed as a continuous “survival-time” variable in Cox regression models using data from self-completed assessment forms for children attending a regional specialist CFS/ME service between January 2006 and December 2009. Semi-structured interviews about barriers experienced in accessing healthcare for their child were conducted with nine parents of children aged < 17 years (8 individual and one parent couple). Interviews were digitally recorded and analysed using “thematic analysis”.

RESULTS: 405 children were assessed between 2006 and 2009 and information on school attendance was available on 388. Only 1/125 with severe CFS/ME and 49/263 (19%) with mild to moderate CFS/ME were seen within NICE recommended timeframe. Increased fatigue was associated with shorter time to assessment (HR = 1.15; 95% CI 1.03, 1.29 per unit increase in Chalder fatigue score; P = 0.01). Time-to-assessment was not associated with disability, mood, age or gender. Parents described difficulties accessing specialist services because of their own as well as their GP’s and Paediatrician’s lack of knowledge. They experienced negative attitudes and beliefs towards the child’s condition when they consulted GPs, Paediatricians and Child Psychiatrists. Parents struggled to communicate an invisible illness that their child and not themselves were experiencing.

CONCLUSIONS: GPs, Child Psychiatrists and Paediatricians need more knowledge about CFS/ME and the appropriate referral pathways to ensure timeliness in referral to specialist services.

Treating chronic fatigue syndrome – a study into the scientific evidence for pharmacological treatments

Abstract:

BACKGROUND: Chronic fatigue syndrome, or myalgic encephalomyelitis (CFS), is a severe disabling condition. Patients with CFS usually trial many different medicines, both conventional and complementary. An overview of the pharmacological treatments used by CFS patients and the available evidence underpinning the use of these treatments would be of great value to both patients and their healthcare providers.

METHODS: Ninety-four CFS patients recruited into an Australian study investigating immunological biomarkers filled out a questionnaire assessing the medicines they were taking. Evidence from randomised clinical trials was sought in biomedical databases.

RESULTS: The 94 CFS patients used 474 different medicines and supplements. The most commonly used medicines were antidepressants, analgesics, sedatives, and B vitamins. We identified 20 randomised controlled trials studying these medicines in CFS patients.

DISCUSSION: While conventional and complementary medicines are widely used by CFS patients, the evidence for effectiveness in CFS is very limited.
