Eosinophilia is a common laboratory finding with a broad differential diagnosis. Eosinophilia can be classified as primary, secondary, or idiopathic hypereosinophilic syndrome (HES). Primary eosinophilia results from a clonal disorder of eosinophils, while secondary eosinophilia is reactive to a variety of underlying conditions, such as allergic diseases, infections, and drug reactions.

Therefore, we systematically reviewed the literature on the efficacy of therapies on ENT manifestations in AAV.
Methods: A systematic review was conducted in accordance with the PRISMA guidelines, searching Medline, Embase and Cochrane libraries, including clinical studies between January 2005 and January 2022, in adults with AAV and ENT involvement, reporting on the effects of local and systemic therapy.
The aim of this study was to identify the role of nasal Staphylococcus aureus (S. aureus) colonization and the effect of systemic or local antibiotic treatment on disease activity in patients with antineutrophil cytoplasmic antibodies (ANCA) associated vasculitis and ear nose and throat (ENT) involvement. Clinical, laboratory and histological data from all patients with ANCA-associated vasculitis and ENT involvement, who were diagnosed in two medical centres in The Netherlands between 1981 and 2020, were retrospectively collected.
