Active clinical trials for "Fatigue Syndrome, Chronic"

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.

Chronic fatigue syndrome (CFS) is a debilitating condition of unknown etiology. Recent studies have shown that CFS is associated with impaired cellular energetics and low levels of phosphocreatine. Since guanidinoacetic acid (GAA) acts as a highly bioavailable precursor of creatine it may provide an ideal dietary supplement to facilitate treatment and perhaps prevention of CFS. The overall hypothesis to be evaluated is that medium-term supplementation with GAA will improve clinical outcomes in well-defined adult CFS patients via augmented provision of creatine. Specific aims: (1) To determine the effects of GAA on CFS symptomatology using a fatigue severity inventory, soreness of locomotive apparatus scales, and a health-related quality of life survey; (2) To determine the effect of GAA on creatine metabolism using laboratory studies and magnetic resonance spectroscopy; (3) To characterize the physiological effects of GAA on work capacity via actigraphy and exercise performance tests; and (4); To determine the prevalence of subjectively reported side-effects and biochemical adverse events associated with GAA intervention.

Patients with HCV infection often suffer from chronic fatigue, depression and reduced cognition, even before evolving severe liver fibrosis, liver cirrhosis and hepatic encephalopathy. It is currently unclear to what extent the symptoms er due to a direct pathological effects of the virus itself, or due to pre-existing psychiatric disease. There is a complex relationship between prior or existing drug abuse, psychiatric disease and HCV infection, that makes it difficult to establish cause-effect relationships. A biological mechanism has been suggested to contribute to development of cerebral dysfunction in the patients. According to the prevailing Trojan Horses hypothesis circulating lymphocytes cross the blood brain barrier carrying HCV to the central nervous system and virus is subsequently replicated in the macrophages and the microglia in brain as a separate compartment. As part of the immunological response to viral replication, neurodegenerative processes takes place with a harmful effect on the neural circuit and cerebral function. Identification of HCV RNA negative strand, a replication product, in brain tissue from HCV patients, as part of autopsy studies, supports the hypothesis. Moreover, HCV patients have also been observed with abnormal metabolic concentrations in the frontal white substance and the basal ganglia by MRI spectroscopy compared to control groups. The overall study objective is to assess cerebral function with particular emphasis on cognitive functions in HCV patients (genotypes 1,2,3 and 4) by use of a neuropsychiatric test battery. Furthermore, the patients will be examined by MRI, including magnetization transfer, diffusion tensor and contrast perfusion, in order to perform measurements of cerebral volumetric and microstructure. Finally, HCV analysis, including viral sequences and cytokine profiles, in serum and cerebrospinal fluid will be carried out in the study population.

The Overall Aim of the present proposal is to evaluate the feasibility of an integrated mind-body intervention, Activate for Life, to improve overall physical activity and mental health and reduce pain and fatigue, resulting in increased likelihood of Aging in Place. Both subjective self-report (i.e., Patient-Reported Outcomes Measurement Information System PROMIS measures of pain, fatigue, depression and anxiety) and objective accelerometer data will be collected, along with standardized measures of balance, strength, and stability. In addition, the measures will be complemented with biomarker-based measures of stress, including cortisol based and 1,5-AG anhydroglucitol assays before, during, and after treatment that are correlated with stress, and fatigue symptoms.

The objective of this study is to measure sympathetic nervous system function and stress responses in patients with clinically documented and self-reported chronic fatigue that is worsened by stress, compared to healthy controls. Baseline norepinephrine (NE) levels and stress-induced NE levels in patients who fulfill criteria for Chronic Fatigue Syndrome (CFS) and who self-identify with stress induced worsening fatigue, will be compared to data from normal individuals pre and post-stress.

The aim of the study is to develop, carry out, evaluate and measure the effects of a new patient education program for patients with Chronic Fatigue Syndrome (CFS)in primary healthcare. In an randomized controlled trial design the effects of the patient education program on coping, physical functioning, fatigue, pain, acceptance, anxiety, depression, quality of life, self- efficacy, and illness perception will be compared with treatment as usual. The results of the main project will lead to the elaboration of the final patient education program that can be implemented in primary health care, as well as development of a training program for future program-conductors.

The Synergy Trial will evaluate the safety and efficacy of a currently available medication (methylphenidate hydrochloride) combined with a CFS-specific dietary supplement (CFS Nutrient Formula) to treat Chronic Fatigue Syndrome (CFS).

Chronic fatigue syndrome is a group of syndrome and is prevalent in adult. Thunder-fire moxibustion is a commentary therapy belonged to acupuncture therapy. To evaluate the effect and safety of thunder-fire moxibustion therapy for chronic fatigue syndrome, we apply a randomized controlled trial by recruiting chronic fatigue syndrome patient as subject, applying thunder-fire moxibustion on shenque acupoint contrasted to common moxa-stick moxibustion, taking fatigue rating scale score, the content of CD3+、CD4+、CD8+、CD4+/CD8+ as evaluation indexes. The treatment time is 20-30 minutes per session, 3-4 times a week, there are totally 15 sessions.

This study is to disclose the mechanism of characteristic Tao yin exercises regulate Chronic Fatigue Syndromes based on Brain-Gut Axis.Explore the clinical manifestation of Chronic Fatigue Syndromes, changes of neurotransmitter and central brain function. Then provide some new methods of treating Chronic Fatigue Syndromes.

We and others have shown that many younger patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) have orthostatic intolerance (OI), i.e., they can't tolerate prolonged standing. OI in ME/CFS is often accompanied by either postural tachycardia syndrome (POTS) in which standing results in an excessive heart rate, and neurally mediated hypotension (NMH) in which standing causes a fall in blood pressure and fainting. Intravenous fluids can alleviate these symptoms, but is difficult to administer; oral fluids fail to provide the same benefit. We would therefore like to test the effectiveness of an oral rehydration solution (ORS, W.H.O. formula) making use of co-transport of glucose and sodium, to reverse these symptoms in ME/CFS subjects with POTS or NMS, and will compare these results with healthy control subjects.
