Nasal Microbiome in ANCA Associated Vasculitis and Relapsing Polychondritis (NMB)

The purpose of this study is to examine the community of microbes living in the noses of patients with ANCA-associated vasculitis (AAV) and to compare the composition of their nasal microbiome with those of healthy controls (those who do not have AAV) over time and correlate disease activity.

Study Duration: 2 to 3 years
