Study Summary

To date, there are no reliable diagnostic blood markers of adult vasculitis. To date, the diagnosis of vasculitis is based on invasive procedure, biopsy of affected tissues potentially at risk of complication . In addition, there are no reliable biomarkers to predict the evolution of vasculitis (relapse, refractory form ...) necessary for the management of patients (type of treatment, duration ..)

Prospective study, monocentric (CHU de Tours), non-interventional, aimed at finding diagnostic and prognostic biomarkers (both metabolomic and immunologic) in adult vasculitis patients.
