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.


To understand how COVID-19 affects inflammation, the immune system, and blood vessels in adults and children with autoimmune diseases.


People ages 15 and older who have been diagnosed with an autoimmune disease or are a healthy volunteer


Participants will have a screening visit. This will include:

Medical history and physical exam


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.


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.

Primary Objective:Characterize how COVID-19 modulates systemic inflammation, autoimmunity features, organ damage and vasculopathy in adult and pediatric patients with a previous 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.

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 COVID19 for clinical purposes. Overall outcome following exposure to COVID19 (response to virus, status of rheumatologic disease)
