Filter by:Post-infection chronic fatigue syndromes, such as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and post-COVID-19 condition (Long Covid), are conditions primarily characterized by debilitating fatigue. This fatigue can range from mild, where patients are still able to participate in some social activities (e.g., school, work), to moderate and severe, where sufferers are predominantly homebound and bedridden. As a result, ME/CFS and Long Covid not only negatively impact the quality of life of affected individuals and their caregivers but also represent a substantial and often silent burden on healthcare systems worldwide, including Austria. This is primarily because most cases remain undiagnosed due to the lack of standardized clinical assessments and diagnostic markers. Endothelial dysfunction, which is well known to affect blood flow, oxygen and nutrient delivery, and waste removal in the body, has been described as one of the key factors behind the symptoms experienced by ME/CFS and Long Covid patients. However, the mechanisms that might explain the development of endothelial dysfunction remain largely unexplored. Therefore, this project aims to evaluate key biological aspects related to the function of endothelial cells - a layer of cells lining blood vessels - using plasma samples from an Austrian cohort of ME/CFS and Long Covid patients. We expect that the findings from our study will provide new insights to better understand endothelial dysfunction in post-infection chronic fatigue syndromes, leading to improved patient stratification and tailored treatment alternatives.
Pilot-case-control study on exertion and orthostatic intolerance of adolescents with myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS) compared to age-matched healthy controls (HC).
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.
Telerehabilitation is a great alternative to offering care during a global pandemic. 85% of patients with COVID-19 report persistent symptoms up to 8 months after the infection. There are no clear recommendations for post-covid rehabilitation. The aims of the study are (1) to test the logistic aspect of implanting a hybrid rehabilitation program and (2) to evaluate the acceptability and the potential impact of the program on treating patients with functional limitations and persistent fatigue symptoms. It's a pre and post-study without a control group.
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 purpose of this study is to evaluate whether a 3-month period of quercetin supplementation (500 mg of Quercetin Phytosome®) is useful in the treatment of chronic fatigue, as assessed by the Fatigue Impact Scale (FIS-40). Secondary end points are sleep assessment through Pittsburgh Sleep Quality Index (PSQI) and muscle performance assessment through the Short Physical Performance Battery (SPPB) and body composition assessment using DXA.
The objective of this study is to explore the role of neuroticism, perceived stress, and adverse life events, respectively, in the development and perpetuation of functional somatic disorders.
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 1. healthy individuals, and 2. individuals with severe physical disease.
Many patients do not recover following Covid infection. The resulting illness is called Long Covid. Because there is no agreed upon treatment for this ailment, the research team has decided to do an open label pilot study using non-invasive, transcutaneous stimulation of the auricular branch of the vagus nerve. Inclusion criteria required the patient to fulfill criteria for having chronic fatigue syndrome. To date, fourteen patients provided evaluable data. Eight of these fulfilled the study's requirements for treatment success.
Coronavirus-2019 (COVID-19) is a viral disease leading to respiratory dysfunction, but it may also affect the brain and result in the development of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). This may be the result of the COVID-19 virus infecting regions of the brain responsible for respiratory control. The symptoms of COVID-19 long haulers and ME/CFS may be lessened via an 8-week inspiratory muscle training protocol which is a simple and easy training protocol which can be done at a patient's home. Thus, this project will investigate changes in the breathing and cardiovascular responses to stimuli in three groups of participants: 1) healthy control individuals; 2) patients diagnosed with ME/CFS (mild to moderate symptoms); and 3) individuals with previous COVID-19 infection with long-haul symptoms lasting for at least 3 months. Participants will 1) breathe hypoxic gas (10% O2) for 5 minutes; 2) breath hypercapnic gas (5% CO2) for 5 minutes; 3) breathe at a rate of 6 breaths per minute for a total of 8 breaths (paced deep breathing); and 4) complete 10 minutes upright tilt (70 degrees head up on a tilt-table). Patients will also complete 2 questionnaires concerning their symptoms and a 15 minute cognitive function test on a lab laptop. This will allow for the assessment of the brain's control over blood pressure and breathing. Participants will also complete a 6-minute walking exercise test at their own speed as a measure of their aerobic fitness. We hypothesize that COVID-19 survivors will have a worse cardiovascular and autonomic response and lower fitness, similar to ME/CFS patients, compared to healthy participants.Further, this will be improved after 8-weeks of inspiratory muscle training. These results may help clinicians recognize ME/CFS symptoms in patients recovering from COVID-19.
