Around 10% of patients after mild or moderate COVID-19 develop Post-COVID Syndrome (PCS), and some meet ME\u002FCFS criteria after six months. No causal treatment exists for ME\u002FCFS or PCS; current approaches are symptomatic and rehabilitative. Given the high and increasing number of affected patients, there is an urgent need for evidence-based, standardized therapies.\n\nImmunoadsorption (IA) is an established treatment for several autoimmune diseases. The first study demonstrating successful IA use in PCS-associated ME\u002FCFS was published by our group in 2024. Earlier proof-of-concept studies (2018, 2020) in infection-related ME\u002FCFS also showed symptomatic improvement in most patients.\n\nHypothesis:\n\nAntibody depletion through IA improves symptoms in the majority of patients with autoantibody-positive ME\u002FCFS and is associated with altered memory B-cell profiles before treatment.\n\nObjective:\n\nTo observe and document symptom progression in 50 ME\u002FCFS or PCS patients undergoing IA, and to examine whether changes in memory B-cells before treatment are linked to therapeutic response.\n\nThe study is conducted as a non-interventional observational study. IA using the TheraSorb® column (Miltenyi) is performed within its approved clinical application.",[26,27],"Myalgic Encephalomyelitis\u002FChronic Fatigue Syndrome (ME\u002FCFS)","ME\u002FCFS Following COVID-19",[26,29,30,31],"Post-COVID Syndrome (PCS)","Immunoadsorption (IA)","SF-36 Physical Function (PF)","RECRUITING","2026-04-13",{"date":35,"type":36},"2026-04-14","ACTUAL",{"date":38,"type":36},"2026-03-11",{"date":40,"type":22},"2027-12-31",{"name":42,"class":43},"Charite University, Berlin, Germany","OTHER"]
