Prevalences of polyarteritis nodosa, microscopic polyangiitis, Wegener's granulomatosis, and Churg‐Strauss syndrome in a French urban multiethnic population in 2000: A capture–recapture estimate

Abstract

This study provides the first prevalence estimates for these 4 vasculitides for a multiethnic, urban population. The significantly higher prevalence observed for Europeans may infer a genetic susceptibility of Caucasians. Compared with previous estimates based mostly on rural populations, the higher frequency of PAN and the lower frequency of WG might suggest specific environmental etiologic factors.
