About this trial
Some people continue to have serious symptoms long after COVID-19, such as extreme fatigue and feeling worse after activity. In some patients, this may happen because the immune system is attacking the body by mistake.
This study will test a treatment called immunoadsorption, which filters the blood to remove harmful antibodies. People with long COVID who have these antibodies will be randomly assigned to receive either the real treatment or a placebo. The main goal is to see whether fatigue improves after one month, and whether other symptoms and daily functioning improve over six months.
This research will help us find out if this treatment can benefit the group of long COVID patients with immune-related disease.
