A vizsgálatról
Mit akar kideríteni a vizsgálat
The goal of this study is to investigate whether mitochondrial dysfunction is present in patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) by subgrouping them into autonomic phenotypes. The main questions it aims to answer are:
A teljes eredeti leírásKevesebb
* When patients with ME/CFS are exposed to situations stressing the mitochondria and autonomic nervous system, is the response of their mitochondria and autonomic nervous system dependent on to which autonomic profile the patients belong? * Is the presence of mitochondrial dysfunction dependent on to which autonomic profile a patient with ME/CFS belongs? Researchers will compare healthy control subjects because very little is known about the link between mitochondria and the autonomic nervous system. It is therefore important that this is also investigated in healthy control subjects to gain a better understanding of which biological changes are normal and which changes may be involved in the symptoms of patients with ME/CFS.
Participants will:
* Undergo an exercise test (to stress the mitochondria) and an orthostatic test (to stress the autonomic nervous system) * Fill in questionnaires * Undergo blood collection

- Healthy controlsA vizsgált kezelés
Study participants will visit the hospital twice with two weeks in between the visits. During each visit, autonomic, clinical and biological outcomes will be assessed before and after the experimental procedure, which include a single bout of submaximal exercise (Aerobic Power Index) to create a high-energy demand situation and stress the mitochondria, and an orthostatic test (Active Standing test) to stress the autonomic nervous system (ANS). The order of these experimental procedures is defined by randomly dividing all participants into two groups. Additionally, this project will assess the presence and severity of post-exertional malaise (PEM) 24h and 7 days after the experimental procedure via online assessments allowing us to determine whether autonomic phenotype and mitochondrial function can predict PEM severity.
