The study is
being done to learn more about Eosinophilic Granulomatosis with Polyangiitis
(EGPA), also known as a Churg-Strauss, a disease that affects the medium and
small blood vessels in the body. The purpose of this study is to discover new
biological markers (biomarkers) in patients with EGPA that will: a) measure the
amount of active disease occurring at any given time b) predict what types of
problems patients are at risk for in order to help choose the best treatment c)
predict whether patients will respond to specific treatments We will collect
clinical information, information from research questionnaires, and blood and
urine samples. Patients will be in the study for 15 years. We are not studying
any new or experimental treatments.
Clinical information and blood and urine specimens will
be collected at your usual clinic visits. The types of information collected
will include medical history details, medication use, physical exam findings,
results of laboratory and diagnostic imaging tests (x-rays, MRIs, PET scans).
Blood and urine specimens will be collected and sent to research laboratories
that are looking to discover proteins, genes, and other chemicals that could
serve as new biomarkers. Biomarkers are molecules that that can be used to
measure biological processes in the body. This study is a project of the
Vasculitis Clinical Research Consortium (VCRC), which is a consortium of
investigators in major North American vasculitis centers. The VCRC is funded
through the National Institutes of Health as a Rare Diseases Clinical Research
Network with the purpose of promoting research in vasculitis.
