Active clinical trials for "Fatigue Syndrome, Chronic"

The objective of this observational study is to estimate the number of weeks of welfare benefits, i.e. sickness benefit, unemployment benefit and social assistance, for individuals with functional somatic disorders and compare them to healthy individuals, and individuals with severe physical disease.

The goal of this observational case-control study is to learn about direct healthcare use and costs of functional somatic disorders. The aim of the proposed study is to investigate the use and costs of direct healthcare for individuals with functional somatic disorders. Researchers will compare direct healthcare use and costs of individuals with functional somatic disorders and compare them with that of healthy controls and individuals with other severe physical disease, respectively.

The objectives of this study are: Firstly, to investigate the association between psychiatric disorders and functional somatic disorder (FSD). Secondly, to investigate whether psychiatric disorders are risk factors for newly developed (incident) FSD after a 5-year follow-up period.

Objectives: Chronic Fatigue Syndrome (CFS) is a medically unexplained condition characterized by severe and disabling fatigue. To date much research has focused on finding out whether CFS is caused by mainly physical or psychological factors. Perhaps as a result of this, few studies have examined the relationship between CFS and quality of life, in particular, more positive aspects of mental health, such as an individual's sense of purpose, autonomy and close relationships. This study will address these limitations by examining Ryff's (1989) six domains of psychological well-being (PWB), and other aspects of well-being including positive emotions, in CFS. It will also examine the relationship between measures of symptomology, emotional distress and PWB. Method: This is a cross-sectional, questionnaire-based study with a clinical sample of adults with CFS. Participants will complete valid measures of well-being and symptomology. Results: We expect to find that compared to general population norms, individuals with CFS score lower on measures of PWB. Secondly, we expect PWB dimensions will be related to symptom measures. There are however, no grounds for making strong predictions. Implications: This study will advance our understanding of quality of life in CFS. Clinically, it has the potential to enrich and inform therapeutic interventions.

To collect blood and urine samples from patients with Chronic Fatigue Syndrome (CFS), myalgic encephalomyelitis (ME), and SEID (Systemic Exertion Intolerance Syndrome) and controls for genomic, viral and metabolomic testing.

The purpose of this study is: To identify specific set of proteins in the cerebrospinal fluid (fluid surrounding the brain and the spinal cord), that are believed to be seen in Chronic fatigue syndrome (CFS) patients, but not in healthy controls (HC). A similar study that the investigators had conducted before,suggested that significant changes in proteins in the cerebrospinal fluid may be due to the fundamental pathology of this disorder. Increased cerebrospinal fluid pressure (pressure that helps the cerebrospinal fluid to move around the brain and the spinal cord), may be related with certain symptoms like headache, sleep problems, light headedness, increased pain, excessive tiredness (fatigue) even with minimal work and memory problems. Assessment of Autonomic Nervous system function (Sympathetic nervous system)between the CFS and HC. Perform Lung Function Testing or pulmonary function test to estimate the lung capacities and score shortness of breath while performing breathing maneuvers. Dolorimetry (18 tender point test) for assessment of pain threshold. Capsaicin skin test Allergy skin test

The investigators will assess the feasibility of activity monitoring armbands for continuous measurement of physical activity level in ME/CFS patients, during 6 months follow-up. The main purpose is to assess if continuous measurement of activity level may be incorporated in outcome measures in future clinical interventional trials.

Coronavirus disease 2019 (COVID-19) is a serious respiratory disease that results from infection with a newly discovered coronavirus (SARS-COV-2). Unfortunately, COVID-19 is not only a short-term infection but that patients (pts) recovering from SARS-COV2 infection complain of persisting symptoms including: fatigue, diffuse myalgia and weakness, which may lead to chronic fatigue syndrome. There is currently no evidence that nutritional supplements and/or physical exercise can assist in the recovery of pts with chronic fatigue syndrome. 1-Methylnicotinamide (1-MNA) is an endogenic substance that is produced in the liver when nicotinic acid is metabolized. 1-MNA demonstrates anti-inflammatory and anti-thrombotic properties. Therefore, we investigated whether 1-MNA supplements could improve exercise tolerance and decrease fatigue among patients recovering from SARS-COV-2.

Primary Hypothesis: Gulf War veterans will have an equal prevalence or mean level of the following medical and psychological conditions frequently reported in the literature compared to a control group of nondeployed veterans: (1) chronic fatigue syndrome, (2) fibromyalgia, (3) post-traumatic stress disorder, (4) neurologic abnormalities, including peripheral neuropathy and cognitive dysfunction, and (5) general health status.
