Brief Summary

The evidence for an autoimmune etiology in postinfectious myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is growing. The investigators observed in a not yet published study that in ME/CFS triggered by COVID, similar to ME/CFS after other infections, there is a close correlation of ß2 adrenergic receptor (ß2R) autoantibodies with symptom severity. Immunoadsorption (IA) to remove autoantibodies has been used successfully in many autoantibody-mediated diseases. The investigators have already performed two proof of concept studies of IA in postinfectious ME/CFS with elevated ß2R antibodies, which resulted in improvement in most patients. This observational study aims to assess symptom outcome and functional ability in 20 patients with Post-COVID Syndrome (PCS) meeting ME/CFS diagnostic criteria with elevated ß2R antibodies undergoing antibody depletion by IA. The study will be conducted as a non-interventional observational study. IA with Miltenyi's TheraSorb® column in PCS will be performed in the approved use. Patients who have symptom improvement after the 1st IA will receive two additional IAs at 3 and 6 months, which will also be documented. The results of this observational study will provide the basis for a randomized controlled clinical trial (RCT) combining IA with B-cell depletion therapy preferentially with Obinutuzumab.

Outcome Measures

Primary Outcomes (1)

  • Improvement in Physical Function (PF) as measured by the Short Form 36 Health Survey Questionnaire (SF-36)

    The Short Form 36 Health Survey (SF-36) is an established and widely used health-related quality of life measure. The Physical Function (PF) domain asks patients to report limitations on ten mobility activities, such as walking specified distances, carrying groceries, and bathing or dressing. Scores are weighted and transformed into a scale ranging from 0 (greatest possible health restrictions, i.e., severe disability) to 100 (no health restrictions). An intra-patient change of 10 points in SF-36-PF from baseline to week four is considered clinically meaningful.

    4 weeks after first IA

Secondary Outcomes (12)

  • Efficacy of repeat immunoadsorptions (IA) on Physical Function (PF) as measured by the Short Form 36 Health Survey Questionnaire (SF-36)

    3 - 6 months after first IA

  • Response duration of repeat immunoadsorptions (IA) on Physical Function (PF) as measured by the Short Form 36 Health Survey Questionnaire (SF-36)

    3 - 6 months after first IA

  • Improvement in ability to work in daily hours

    12 months after last IA

  • Improvement in physical and mental fatigue as measured by the Chalder Fatigue Scale

    4 weeks after first IA; 6 and 12 months after last IA

  • Improvement in fatigue as measured by the Fatigue Severity Score (FSS)

    4 weeks after first IA; 6 and 12 months after last IA

  • +7 more secondary outcomes

Interventions

IA cycle is 5 days, repeat cycles will be given to responders at months 3 and 6

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients presenting at the investigators' outpatient clinic who meet the CCC for ME/CFS (PEM for at least 14h or longer) and who are found to have elevated ß2R autoantibodies will be offered an IA and participation in this observational study. Also, PCS patients who do not meet CCC criteria due to shorter PEM (\< 14h) but meet Systemic Exertion Intolerance Disease criteria may receive IA and be enrolled in the study.

You may qualify if:

  • Consenting patients aged 18-65 years with a diagnosis of Post-COVID ME/CFS according to the Canadian Consensus Criteria (CCC) or fulfilling CCC with exertion intolerance with symptom worsening (post exertional malaise = PEM) duration of less than 14 hours (thus fulfilling Institute of Medicine criteria)
  • Evidence of COVID infection at disease onset (PCR) or N-IgG
  • Detection of autoantibodies (elevated ß2 receptor adrenergic autoantibodies)
  • Immunoadsorption with the TheraSorb® column for 5 days
  • Health insurance

You may not qualify if:

  • Lack of willingness to store pseudonymized disease data as part of the study
  • Pregnancy
  • Other illnesses that do not allow the diagnosis of PCS to be made with certainty (e.g., heart failure, lung disease, severe depression, cancer)
  • Acute infection (COVID, HIV, hepatitis)
  • Severe fatigue disease with bedriddenness
