What this trial studies

This clinical trial investigates the effectiveness of repeated immunoadsorption interventions in patients suffering from chronic fatigue syndrome (CFS), including those with post-acute COVID-19 syndrome (PACS-CFS). Participants will be randomly assigned to receive either the immunoadsorption treatment or a sham treatment over a period of 10 days, followed by a 6-month follow-up. The primary goal is to assess clinical improvement in fatigue and other symptoms using the Chalder Fatigue Scale. The study also aims to evaluate the safety and tolerability of the treatment in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 diagnosed with ME/CFS or PACS-CFS, who have detectable autoantibodies.

Not a fit: Patients with severe comorbidities, acute psychiatric conditions, or those who have experienced fatigue for five years or more may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly alleviate fatigue and improve the quality of life for patients with chronic fatigue syndrome and post-COVID fatigue.

How similar studies have performed: While there is growing interest in immunoadsorption for autoimmune conditions, this specific approach for CFS and PACS-CFS is relatively novel and has not been extensively tested in prior studies.
