简要总结
This study is testing a new treatment for people with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and long-term symptoms after COVID-19. Both conditions cause extreme fatigue, muscle pain, "brain fog," and trouble concentrating, which often get worse after physical or mental activity. Currently, no effective treatments are available.
The treatment being studied is called Intermittent Hypoxia-Hyperoxia Treatment (IHHT). It uses a machine called HypoxBreath to deliver short cycles of low oxygen (hypoxia) and high oxygen (hyperoxia) through a mask. Each session lasts 22-40 minutes and is carefully monitored to track oxygen levels, heart rate, and breathing. The therapy is customized for each patient to ensure comfort and effectiveness. IHHT is believed to help the body adapt to oxygen-related stress, improving energy production and reducing inflammation.
In this trial, 104 patients with ME/CFS will be randomly assigned to receive either IHHT or a placebo treatment with normal oxygen levels over eight weeks. The placebo group will follow a similar procedure without oxygen changes. An additional 20 healthy individuals will be recruited as a comparison group, but they will not undergo the treatment.
Participants will have medical check-ups before and after treatment to evaluate changes in fatigue, mental sharpness, pain, autonomic nervous system function, and overall quality of life. Blood samples and small skin biopsies will also be taken to study the biological processes behind ME/CFS and how the treatment works.
This research aims to find out if IHHT can improve the lives of people with ME/CFS or long-term COVID symptoms. The results could also provide new insights into the causes of these challenging conditions and guide future treatments.

研究组 & 干预措施
Intermittent hypoxia-hyperoxia treatment (IHHT)
An individualized treatment is administered to patients in 4-7 intervals, within 22-40 minutes. Blood oxygen saturation (O2-Sat) rises and falls cyclically, due to fluctuating fractions of inspired oxygen (FiO2): 9-13% in the hypoxic phase and 36% in the hyperoxic restitution phase.
干预措施: Intermittent hypoxia-hyperoxia treatment (IHHT) (Other)
Sham treatment
The placebo group will undergo 'sham treatment' with air breathing at 21% FiO2. To equate the sensation of IHHT, airbrakes will be simulated similar to the IHHT intervals in the treatment protocol.
干预措施: Placebo (Device)
