Redefining Autoimmune Diseases Across Rheumatology (RADAR)

The goal of this study is to understand the molecular changes (tissue and cell reactions) in the immune system that happen before and during relapse/disease flares, disease progression, or responses to treatment in adults with vasculitis. If we can better understand the changes in the immune response, we may be able to understand the cause of these diseases and develop better tests and therapies. Participants have nasal swabs taken, blood and urine collected, and fill out questionnaires. Study assessments are done at your usual clinic visits with your rheumatologist at Penn.
