Natural History of Coronavirus Disease (COVID-19) in Systemic Autoimmune Diseases
- Conditions
- Systemic Autoimmune Diseases
- Registration Number
- NCT04690816
- Lead Sponsor
- National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS)
- Brief Summary
Background:
Viral infections such as COVID-19 may lead to flare-ups in people with systemic autoimmune diseases (SAD). These infections may also change the function of their immune system and/or cause problems with their blood vessels. Researchers want to learn how people with SAD respond to treatments or vaccines for COVID-19.
Objective:
To understand how COVID-19 affects inflammation, the immune system, and blood vessels in adults and children with autoimmune diseases.
Eligibility:
People ages 15 and older who have been diagnosed with an autoimmune disease or are a healthy volunteer
Design:
Participants will have a screening visit. This will include:
Medical history and physical exam
EKG
Chest x-ray
COVID-19 test. A swab will be put in the participant s nose or the back of their mouth.
Blood and urine tests
Participants will be placed into 1 of 4 groups:
1. Those with previously documented COVID-19 infection or COVID vaccination
2. Those with a recently known COVID-19 exposure or vaccination
3. Those with no known COVID-19 exposure or vaccination
4. Those who developed an acute COVID-19 infection
Depending on their group, participants will have 1 to 5 more visits. These will occur over 12 to 18 months. Visits may include:
FDG PET/CT scan. Participants will lie in a doughnut-shaped machine. The machine creates pictures of the body. For the scan, they will have a radioactive substance injected into their arm through an IV.
Kidney function tests
Non-invasive vascular studies test. These tests are similar to what it feels like to have blood pressure checked.
- Detailed Description
Study Description:
This is an observational study to characterize how COVID-19 modulates systemic inflammation, autoimmune features and vasculopathy in adult and pediatric patients with a prior diagnosis of systemic autoimmunity, and their overall outcomes including response to potential antiviral treatments or vaccines.
Objectives:
Primary Objective: Characterize how COVID-19 modulates systemic inflammation, autoimmunity features, organ damage and vasculopathy in adult and pediatric patients with a diagnosis of systemic autoimmunity. Characterize how exposure to a COVID vaccine modulates systemic inflammation, autoimmunity features and vasculopathy in adult and pediatric patients with a diagnosis of systemic autoimmunity. Assess how subjects with systemic autoimmunity respond to COVID-19 regarding antiviral and/or proinflammatory responses and overall outcomes
Secondary Objectives: Understand prevalence and severity of COVID-19 in individuals with autoimmune diseases, and the variables that associate/predict these responses.
Endpoints:
Primary Endpoint: Immune dysregulation and vasculopathy modulation following COVID-19.
Secondary Endpoints: Immunologic and clinical response to potential antiviral/immune modulator treatments and/or vaccines that are used during COVID-19 for clinical purposes. Overall outcome following exposure to COVID-19 and/or COVID vaccine (response to virus, status of rheumatologic disease)

- Secondary Outcome Measures
Name Time Method Understand prevalence and severity of COVID-19 in individuals with autoimmune diseases, and the variables that associate/predict these responses. 48 months Clinical outcomes, as assessed by disease-specific activity/severity measures in response to COVID infection. Response to potential antiviral treatments and/or vaccines that are used for clinical reasons in response to COVID-19 exposure or prevention.
