Olfactory dysfunction in antineutrophil cytoplasmic antibody-associated vasculitides: A review of the literature

Alfonso Luca Pendolino et al. World J Methodol. .

Abstract

Olfactory dysfunction (OD) has been described in patients with antineutrophil cytoplasmic antibody-associated vasculitides (AAV), but the underlying mechanisms are not completely understood. The causes of altered smell function can generally be divided into conductive, sensorineural or others. To date no specific treatment is available for AAV-related OD and the efficacy of currently available options has not been explored. The aim of this review is to provide an overview of the causes that may lead to OD in patients with AAV. Current available treatments for OD and possible options in patients with AAV presenting with smell impairment are also mentioned.

Keywords: Antineutrophil cytoplasmic antibody-associated vasculitis diseases; Eosinophilic granulomatosis with polyangiitis; Granulomatosis with polyangiitis; Microscopic polyangiitis; Olfactory dysfunction; Smell.
