A Longitudinal Study on Longstanding Complicated Fatigue
Sponsor: Stockholm University
Summary
The purpose of the study is to investigate if there are common biopsychosocial vulnerability factors for developing and maintaining fatigue, regardless of the diagnosis. The investigators also believe that subgroups differ in terms of these factors. Participating patients with ME/CFS, burnout syndrome and post-covid fatigue complete a web form at inclusion and after 1, 2, 4, 6, 12, 18 and 24 months. There is no upper limit for the number of participants in the web survey. 150 participants are asked to submit blood samples at a local laboratory in connection with the questionnaires for analysis of inflammatory markers and one urine sample for analysis of nutritional markers. Two control groups are included, 150 patients with rheumatoid arthritis and 50 healthy individuals. The longitudinal design makes it possible to investigate how inflammatory markers, nutritional status, symptom burden, health related quality of life co-vary over time and how work ability and sick leave is affected.
