Hyperbaric Oxygen Therapy for Post-COVID Syndrome and Chronic Fatigue

Observational Study of Hyperbaric High Pressure Oxygen Therapy (HBOT) in Patients with Post-COVID Syndrome (PCS) and Myalgic Encephalomyelitis/chronic Fatigue Syndrome (ME/CFS)

Observational Charite University, Berlin, Germany · NCT06118138

What this trial studies

This observational study aims to document symptom progression in 60 patients diagnosed with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) who will undergo Hyperbaric Oxygen Therapy (HBOT) following COVID or other infections. Participants will complete health evaluations, including questionnaires like the SF-36, to assess changes in ME/CFS-related symptoms after receiving HBOT. The focus is on observing and documenting these changes rather than evaluating the efficacy of HBOT itself, providing insights that could inform future randomized controlled trials.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 who have been diagnosed with ME/CFS and have previously participated in the CFS_CARE study.

Not a fit: Patients with acute infections, severe medical conditions, or those unwilling to consent to data storage may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into symptom management for patients suffering from ME/CFS and post-COVID syndrome.

How similar studies have performed: While the approach of using HBOT for ME/CFS is being explored, this specific observational study is novel and aims to document symptom progression rather than test efficacy.
