Somatic comorbidities in irritable bowel syndrome: fibromyalgia, chronic fatigue syndrome, and interstitial cystitis

Abstract:

Fibromyalgia, chronic fatigue syndrome, and interstitial cystitis frequently overlap with irritable bowel syndrome (IBS). There is a positive correlation between the incidence of these comorbidities and increased health care seeking, reduction in quality of life, and higher levels of mood disorders, which raises the question of a common underlying pathophysiology. A possible central hypersensitization disorder seems to be particularly involved in the dysfunction of bidirectional neural pathways and viscerovisceral cross-interactions within the CNS, thus explaining these many extraintestinal manifestations in IBS.

Chronic fatigue syndrome: aetiology, diagnosis and treatment

Abstract:

Chronic fatigue syndrome is characterised by intense fatigue, with duration of over six months and associated to other related symptoms. The latter include asthenia and easily induced tiredness that is not recovered after a night’s sleep. The fatigue becomes so severe that it forces a 50% reduction in daily activities.

Given its unknown aetiology, different hypotheses have been considered to explain the origin of the condition (from immunological disorders to the presence of post-traumatic oxidative stress), although there are no conclusive diagnostic tests.

Diagnosis is established through the exclusion of other diseases causing fatigue. This syndrome is rare in childhood and adolescence, although the fatigue symptom per se is quite common in paediatric patients.

Currently, no curative treatment exists for patients with chronic fatigue syndrome. The therapeutic approach to this syndrome requires a combination of different therapeutic modalities. The specific characteristics of the symptomatology of patients with chronic fatigue require a rapid adaptation of the educational, healthcare and social systems to prevent the problems derived from current systems. Such patients require multidisciplinary management due to the multiple and different issues affecting them.

This document was realized by one of the Interdisciplinary Work Groups from the Institute for Rare Diseases, and its aim is to point out the main social and care needs for people affected with Chronic Fatigue Syndrome. For this, it includes not only the view of representatives for different scientific societies, but also the patient associations view, because they know the true history of their social and sanitary needs. In an interdisciplinary approach, this work also reviews the principal scientific, medical, socio-sanitary and psychological aspects of Chronic Fatigue Syndrome.

Cardiovascular dysfunction with low cardiac output due to a small heart in patients with chronic fatigue syndrome

Abstract:

OBJECTIVE: Little attention has been paid to possible cardiovascular involvement in patients with chronic fatigue syndrome (CFS), although many of their symptoms and signs suggest cardiovascular dysfunction. Possible cardiovascular symptoms and cardiac function were investigated in CFS patients.

METHODS: Cardiovascular symptoms were intensively investigated and cardiac function was evaluated echocardiographically.

PATIENTS: Fifty-three patients (23 men and 30 women, mean age: 31+/-7 years) with CFS under 50 years were studied.

RESULTS: Slender build (body mass index <20 kg/m(2)) was common (47%). Possible cardiovascular symptoms including shortness of breath (32%), dyspnea on effort (28%), rapid heartbeat (38%), chest pain (43%), fainting (43%), orthostatic dizziness (45%) and coldness of feet (42%), were all frequent complaints. Hypotension (28%) was occasionally noted. Electrocardiograms frequently revealed right axis deviation (21%) and severe sinus arrhythmia (34%) suggesting accentuated parasympathetic nervous activity. Small heart shadow (cardiothoracic ratio <or=42%) was noted on the chest roentgenogram in 32 patients (60%). Echocardiographic examination demonstrated low cardiac indexes (<2 L/min/m(2)) with low stroke volume indexes (<30 mL/m(2)) due to a small left ventricular chamber in 19 (36%, p<0.05 vs. 8% in 36 controls). None had reduced left ventricular ejection fraction.

CONCLUSION: Cardiovascular symptoms are common in CFS patients. Cardiac dysfunction with low cardiac output due to small left ventricular chamber may contribute to the development of chronic fatigue as a constitutional factor in a considerable number of CFS patients.

Randomized controlled study on influence of acupuncture for life quality of patients with chronic fatigue syndrome

Abstract:

OBJECTIVE: To observe effects of acupuncture on quality of life of patients with chronic fatigue syndrome (CFS).

METHODS: Randomized, controlled and single-blinded study method was used, 70 cases were divided into an observation group and a control group, 35 cases in each group. The observation group was treated with acupuncture at Baihui (GV 20), Danzhong (CV 17), Zhongwan (CV 12), Qihai (CV 6), Guanyuan (CV 4), Hegu (LI 4), Zusanli (ST 36), etc.; the control group was treated with acupuncture at non-meridian points (2 cm to the acupoints), thrice a week. The treatment was given for 14 times. The World Health Organization Quality of Life (WHOQOL-BREF) scale was used to evaluate the patients’ quality of life before and after treatment.

RESULTS: The physiological field, individuals own perception of his health condition and total score were significantly improved after treatment in the observation group (all P<0.05); there were no obvious changes in the psychology, social relationships, environment and subjective feelings about the quality of life (all P>0.05). The score of the environmental field in the control group was significantly decreased compared to that before treatment (P<0.05), and there were no significant changes in the other scores. There were no adverse effects in patients.

CONCLUSION: Acupuncture can improve the quality of life of CFS patients, especially in physiological field and the individual perception to his well being. Acupuncture has high safety, and the acupoints has high specific degree than non-meridian points.

Sleep apnea and psychological functioning in chronic fatigue syndrome

Abstract:

Objectives were to explore: (1) whether sleep apnea/hypopnea syndrome (SAHS) should be considered a chronic fatigue syndrome (CFS) comorbidity, rather than a diagnostic exclusion criterion; and (2) to compare sleep/wake/ psychopathology in individuals with CFS, controls and another illness.

Participants (CFS, SAHS, controls) completed questionnaires and were evaluated for SAHS; 68 percent were subsequently diagnosed with SAHS. CFS participants with and without SAHS did not differ. Both clinical groups were less well adjusted than controls. We conclude that SAHS should not be an exclusion criterion for CFS and that psychological problems in CFS seem a consequence of coping with illness.

Chronic fatigue syndrome: la bête noire of the Belgian health care system

Abstract:

The World Health Organization acknowledges Myalgic Encephalomyelitis (ME)/Chronic Fatigue Syndrome (CFS) to be a medical illness. ME/CFS is characterized by disorders in the inflammatory and oxidative and nitrosative stress (IO&NS) pathways. In 2002, the Belgian government started with the development of CFS “Reference Centers”, which implement a “psychosocial” model. The medical practices of these CFS Centers are defined by the Superior Health Council, e.g. treatment should be based upon Cognitive Behavioral Therapy (CBT) and Graded Exercise Therapy (GET); and biological assessments and treatments of ME/CFS should not be employed.

Recently, the Belgian government has evaluated the outcome of the treatments at the CFS Centers. They concluded that a “rehabilitation therapy” with CBT/GET yielded no significant efficacy in the treatment of ME/CFS and that CBT/GET cannot be considered to be curative therapies.

In case reports, we have shown that patients who were “treated” at those CFS centers with CBT/GET in fact suffered from IO&NS disorders, including intracellular inflammation, an increased translocation of gram-negative enterobacteria (leaky gut), autoimmune reactions and damage by O&NS.

Considering the fact that these findings are exemplary for ME/CFS patients and that GET may even be harmful, it means that many patients are maltreated by the Belgian CFS Centers. Notwithstanding the above, the government and the CFS Centers not only continue this unethical and immoral policy, but also reinforce their use of CBT/GET in patients with ME/CFS treated at those Centers.

A review on cognitive behavorial therapy (CBT) and graded exercise therapy (GET) in myalgic encephalomyelitis (ME) / chronic fatigue syndrome (CFS): CBT/GET is not only ineffective and not evidence-based, but also potentially harmful for many patients with ME/CFS

Abstract:

Benign Myalgic Encephalomyelitis (ME) / Chronic Fatigue Syndrome (CFS) is a debilitating disease which, despite numerous biological abnormalities has remained highly controversial. Notwithstanding the medical pathogenesis of ME/CFS, the (bio)psychosocial model is adopted by many governmental organizations and medical professionals to legitimize the combination of Cognitive Behavioral Therapy (CBT) and Graded Exercise Therapy (GET) for ME/CFS. Justified by this model CBT and GET aim at eliminating presumed psychogenic and socially induced maintaining factors and reversing deconditioning, respectively.

In this review we invalidate the (bio)psychosocial model for ME/CFS and demonstrate that the success claim for CBT/GET to treat ME/CFS is unjust. CBT/GET is not only hardly more effective than non-interventions or standard medical care, but many patients report that the therapy had affected them adversely, the majority of them even reporting substantial deterioration.

Moreover, this review shows that exertion and thus GET most likely have a negative impact on many ME/CFS patients. Exertion induces post-exertional malaise with a decreased physical performance/aerobic capacity, increased muscoskeletal pain, neurocognitive impairment, “fatigue”, and weakness, and a long lasting “recovery” time.

This can be explained by findings that exertion may amplify pre-existing pathophysiological abnormalities underpinning ME/CFS, such as inflammation, immune dysfunction, oxidative and nitrosative stress, channelopathy, defective stress response mechanisms and a hypoactive hypothalamic-pituitary-adrenal axis.

We conclude that it is unethical to treat patients with ME/CFS with ineffective, non-evidence-based and potentially harmful “rehabilitation therapies”, such as CBT/GET.

Physiological cost of walking in those with chronic fatigue syndrome (CFS): a case-control study

Abstract:

PURPOSE: To examine the physiological cost of walking in subjects with chronic fatigue syndrome (CFS) and a matched control group, walking at their preferred and at matched walking speeds.

METHODS: Seventeen people with CFS and 17 matched-controls participated in this observational study of physiological cost during over-ground gait. Each subject walked for 5 min at their preferred walking speed (PWS). Controls then walked for 5 min at the same pace of their matched CFS subject. Gait speed and oxygen uptake, gross and net were measured and oxygen uptake was expressed per unit distance ambulated. CFS subjects completed the CFS-Activities and Participation Questionnaire (CFS-APQ).

RESULTS: At PWS the CFS group walked at a slower velocity of 0.84 +/- 0.21 m s(-1) compared to controls with a velocity of 1.19 +/- 0.13 m s(-1) (p < 0.001). At PWS both gross and net oxygen uptake of CFS subjects was significantly less than controls (p = 0.023 and p = 0.025 respectively). At matched-velocity both gross and net physiological cost of gait was greater for CFS subjects than controls (p = 0.048 and p = 0.001, respectively).

CONCLUSION: The physiological cost of walking was significantly greater for people with CFS compared with healthy subjects. The reasons for these higher energy demands for walking in those with CFS have yet to be fully elucidated.

Phenotypes of chronic fatigue syndrome in children and young people

Abstract:

OBJECTIVE: To investigate the heterogeneity of chronic fatigue syndrome (CFS/ME) in children and young people.

SETTING: Regional specialist CFS/ME service Patients Children and young people aged <19 years old.

METHODS: Exploratory factor analysis was performed on symptoms present at assessment in 333 children and young people with CFS/ME. Linear and logistic regression analysis of data from self-completed assessment forms was used to explore the associations between the retained factors and sex, age, length of illness, depression, anxiety and markers of severity (fatigue, physical function, pain and school attendance).

RESULTS: Three phenotypes were identified using factor analysis: muscoloskeletal (factor 1) had loadings on muscle and joint pain and hypersensitivity to touch, and was associated with worse fatigue (regression coefficient 0.47, 95% CI 0.25 to 0.68, p<0.001), physical function (regression coefficient -0.52, 95% CI -0.83 to -0.22, p=0.001) and pain. Factor 2 (migraine) loaded on noise and light hypersensitivity, headaches, nausea, abdominal pain and dizziness and was most strongly associated with physical function and pain. Sore throat phenotype (factor 3) had loadings on sore throat and tender lymph nodes and was not associated with fatigue or pain. There was no evidence that phenotypes were associated with age, length of illness or symptoms of depression (regression coefficient for association of depression with musculoskeletal pain -0.02, 95% CI -0.27 to 0.23, p=0.87). The migraine phenotype was associated with anxiety (0.40, 95% CI 0.06 to 0.74, p=0.02).

IMPLICATIONS: CFS/ME is heterogeneous in children with three phenotypes at presentation that are differentially associated with severity and are unlikely to be due to age or length of illness.
