Filter by:Postcancer fatigue (PCF) is a frequently occurring, severe and invalidating problem, impairing quality of life. Patients with chronic fatigue syndrome (CFS) also suffer from severe fatigue symptoms. Although it is possible to effectively treat CFS, the nature of the underlying physiology remains unclear. The presence of an underlying immunological problem has been suggested as an explanation for PCF and CFS. The aim of this study is to compare the humoral and cellular immune responses upon influenza vaccination in PCF patients, CFS patients, non-fatigued cancer survivors, and healthy controls. PCF (n=20) and CFS patients (n=20) will be vaccinated against influenza. Age and gender matched non-fatigued cancer survivors (n=20) and healthy controls (n=20) will be included for comparison. Antibody responses will be measured at baseline and at day 21 by a hemagglutination inhibition test. T cell responses will be measured at baseline and at day 7 by lymphocyte proliferation, activation, and cytokine secretion.
The purpose of this study is to test the effects of a videotelephone-delivered patient-partner dual-focused cognitive behavioral stress management intervention on chronic fatigue syndrome (CFS) symptoms and related psychosocial and neuroimmune processes in patients diagnosed with chronic fatigue syndrome. Study tests the hypothesis that videophone-delivered patient-partner cognitive behavioral stress management (T-PP-CBSM) intervention improves patient CFS symptoms relative to a videophone-delivered patient-partner Health Information (PP-T- HI) condition.
Chronic fatigue syndrome (CFS) is a disabling, unexplained disorder characterized by physical and mental exhaustion. Complaints of disturbed and unrefreshing sleep are very common in CFS patients, however, the relationship between (disturbed) sleep quality and fatigue is still not fully elucidated. To evaluate the effect of sodium oxybate on fatigue and to explore the interdependence of sleep quality and fatigue in CFS, a double blind, randomized, placebo controlled cross-over trial with sodium oxybate is carried out in CFS patients. The aim of this study is to address the issue of the effect of sodium oxybate on fatigue as a presenting symptom in chronic fatigue (CF) and CFS patients, in the absence of underlying medical or psychiatric illness. The answer to this question may shed further light on the enigmatic relationship between sleep and fatigue. We also want to investigate the effect of sodium oxybate on sleepiness and general health in the same target population. Zero-hypothesis: there is no effect.
The investigators will conduct acupuncture for participants with chronic fatigue syndrome(CFS). Firstly the investigators aim to figure out the characteristic of sleep structure of CFS and the changes caused by acupuncture. Secondly the investigators seek to investigate the characteristic of sleep-wake rhythm, slow wave sleep(SWS)-rapid eye movement(REM)sleep rhythm, and REM sleep rhythm of CFS and the readjusting of acupuncture for it. Thirdly the investigators want to know the efficacy of acupuncture for relieving the fatigue, reducing accompanying symptoms and for improving the life quality of CFS.
Given the lack of evidence in support of pacing self-management for patients with chronic fatigue syndrome (CFS), it is examined whether physical behavior and health status of patients with CFS improve in response to a pacing self-management program. The effects of pacing will be compared with those observed when applying relaxation therapy to patients with CFS.
The aim of this pilot study for the NorCAPITAL trial is to investigate the feasibility and safety of the drug clonidine in adolescent chronic fatigue syndrome (CFS). Specifically, the investigators wanted to assess appropriate dosage in relation to a) plasma concentration levels of clonidine, b) orthostatic cardiovascular responses (the pulse and blood pressure responses when rising up), and c) reports of possible adverse effects. A possible beneficial effect of clonidine in adolescent CFS will be investigated in NorCAPITAL, which is a randomized, placebo-controlled, double blind trial.
The pathogenesis of chronic fatigue syndrome (CFS) is poorly understood and no effective therapy has been developed. Recent studies suggest that a preceding viral infection causes mitochondrial dysfunction of the brain and skeletal muscle of genetically susceptible individuals. There is no specific laboratory test to identify patients with CFS. However, certain clinical manifestations are similar to those seen in mitochondrial disorders. Both patients with mitochondrial disorders and CFS manifest elevated serum lactate levels after exercise, and demonstrate elevated brain cerebrospinal fluid levels and decreased brain glutathione levels on nuclear magnetic resonance (NMR) spectroscopy. Therapy consisting of daily conditioning exercise, dietary recommendations, and nutraceutical supplements (ENT) has been show to be beneficial in treating patients with mitochondrial disorders. Similar therapy has been instituted in individual patients with CFS and has been shown to also improve their clinical conditions. A placebo-controlled trial will be undertaken in 24 CFS patients aged 25-55. Patients fulfilling the CDC criteria for CFS will participate in this 6 month study. Other medical causes for fatigue will be excluded. Half the patients will receive treatment consisting of daily conditioning exercise plus nutraceutical supplements (ENT), that has been shown to be beneficial for patients with mitochondrial dysfunction, while the other half will receive daily conditioning exercise and placebo tablets. Response to ENT will be evaluated by maximum oxygen consumption (VO2max) and circulating lactate levels during & after treadmill exercise, a 6-minute walk test, and a fatigue questionnaire. In addition, whether ENT corrects the elevated brain cerebrospinal fluid levels and decreased brain glutathione levels will be measured. To ensure compliance to therapy patients will be monitored frequently. The objective of this study is to assess the safety and efficacy of ENT and whether ENT leads to sustained improvement of CFS patients compared to their baseline status, and compared to an exercised group of patients not receiving supplements.
Chronic fatigue (CF) and chronic fatigue syndrome (CFS) are disabling disorders that may be induced or aggravated by underlying sleep disturbances. The relationship between sleep quality and fatigue is still not fully elucidated. To evaluate the effect of improved sleep quality on fatigue, a randomized controlled and cross-over trial with nasal continuous positive airway pressure (nCPAP) is carried out in patients who present with a primary complaint of chronic disabling fatigue and who are found to have an apnea-hypopnea index (AHI) >= 15 on polysomnography (PSG). The aim of this study is to address the issue of Continuous Positive Airway Pressure-responsiveness regarding fatigue as a presenting symptom in CF and CFS patient with obstructive sleep apnea (OSA), in the absence of underlying medical or psychiatric illness. The answer to this question may shed further light on the enigmatic relationship between sleep and fatigue. We also want to investigate the Continuous Positive Airway Pressure responsiveness regarding sleepiness and general health in the same target population. Zero-hypothesis: there is no effect.
The objective of this study is to assess the efficacy of two treatment strategies for fatigue and disabilities in QFS: long term treatment with doxycycline or cognitive behavioral therapy (CBT).
Based on pilot patient observations, and experience from the prior study KTS-1-2008, the investigators anticipate that severely affected chronic fatigue syndrome patients may benefit from B-cell depletion therapy using Rituximab induction with maintenance treatment. The hypothesis is that at least a subset of chronic fatigue syndrome (CFS) patients have an activated immune system involving B-lymphocytes, and that prolonged B-cell depletion may alleviate symptoms. An approved amendment (April 15th 2011): the study will be extended with up to 5 patients. For up to 5 patients in the study, standard plasma exchange may be performed 2-3 weeks prior to start of B-lymphocyte depletion using Rituximab (as in the protocol). Approved amendment (December 2011): for patients with gradual improvement in CFS/ME symptoms after 12 months follow-up, but not having reached a clear response, up to 6 additional Rituximab infusions (500 mg/m2, max 1000 mg) may be given during the following 12 months period.
