Immunoadsorption in Autoimmune Long COVID

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.

Effects of Kneipp Hydrotherapy in Post-COVID-19 Patients

This randomized controlled study evaluates the effects of cold water hydrotherapy in patients with Post-COVID Syndrome. The primary aim is to assess changes in quality of life compared to an usual care setting without hydrotherapy treatment.

Magnetic Resonance Analysis of Neural Inflammatory Factors and External Stimulation

The goal of this clinical trial is to test whether a type of rapid outpatient brain stimulation that uses magnetic fields, called accelerated intermittent theta burst stimulation (iTBS), can treat symptoms such as brain fog, depression, and anxiety in patients with Long COVID. The main questions it aims to answer are: * Is iTBS effective and feasible for reducing Long COVID symptoms? We will measure these symptoms using the Symptom Burden Questionnaire. * Are there changes in inflammatory brain chemicals associated with treatment with iTBS? We will be looking at levels of choline in the brain, which is thought to be related to inflammation. Researchers will compare sham versus active forms of iTBS to see if the active group has greater improvement in symptoms. Participants will complete symptom surveys, cognitive tests, and magnetic resonance imaging scans at the beginning, middle, and end of treatment.

Effect of Pulmonary Rehabilitation and Physical Activity on Long COVID (PuReCOVID)

This single-center, observational, longitudinal, retrospective and prospective study investigates the impact of Active Cycle of Breathing Technique (ACBT) and moderate daily physical activity on symptoms associated with long COVID, such as cough, dyspnea, and fatigue. The study aims to assess whether these interventions can moderately alleviate or resolve these symptoms and evaluate their potential association with small airway dysfunction (SAD), as measured by Impulse Oscillometry (IOS). We will recruit 40 adult patients with long COVID who meet specific inclusion criteria. Participants will perform ACBT twice daily and complete at least 6000 steps per day for six weeks. We will track clinical and lung function parameters, including spirometry, IOS, and exercise capacity.

Quality of Life After Hyperbaric Oxygen Therapy in Post-COVID Patients

Post-Covid syndrome, also known as long Covid, is a clinical condition in which patients experience long term symptoms after Covid-19 infection. Treatment options for post-Covid are not effective. Therefore, there is an urgent need for a novel therapy. The first study results of HBOT in post-Covid patients are promising. Previous research from Israel has shown improvements in quality of life after HBOT. However, long term results are unknown. Therefore, this study aims to evaluate quality of life at one year after hyperbaric oxygen therapy in post-Covid patients with cognitive symptoms. It is hypothesized that quality of life at one year after HBOT is improved. Furthermore, this study aims to evaluate return to work after HBOT. To our knowledge this was not done before. An observational prospective cohort study will be conducted to answer the research questions. All post-Covid patients who are treated with hyperbaric oxygen therapy in participating centers, will be eligible for inclusion. Questionnaires and medical doctor consultations will be used in order to collect all data. There are no risks for participants, since only 7 questionnaires are not part of standard clinical care. The burden is approximately 40 minutes extra in total for participants, compared to standard clinical care.

Evaluating the Impact of a Functional and Cognitive Strategy in Patients with Long Covid-19

This study aims to evaluate the impact of a functional and cognitive rehabilitation strategy compared to evidence-based informational messages, on functional capacity, cognitive abilities, quality of life, and disease progression in adults with chronic non-communicable diseases (NCDs) and Long Covid-19. Researchers will compare a structured rehabilitation program to informational support through evidence-based messages to determine if rehabilitation leads to better functional and cognitive outcomes in patients with Long Covid-19. Participants will be randomly assigned to one of two groups: 1. Functional and cognitive rehabilitation: Attending weekly in-person sessions for 8 weeks, including supervised physical and cognitive exercises. 2. Informational support: Receiving weekly evidence-based educational messages for 8 weeks. Participants will undergo assessments at baseline, post-intervention, and six months later, including a six-minute walk test, handgrip strength measurement, and questionnaires on disability, anxiety, depression, fatigue, dyspnea, cognitive function, and quality of life.
