Pregnancies in women with antineutrophil cytoplasmatic antibody associated vasculitis

Antineutrophil cytoplasmatic antibody associated vasculitis (AAV) usually manifests after age fifty, thus making it very rare during reproductive age. Although rare, AAV, particularly eosinophilic granulomatosis with polyangiitis, can manifest at a younger age. AAV can also appear for the first time during pregnancy.
