Berti A, et al. - Researchers investigated the role of atopy in patients affected with eosinophilic granulomatosis with polyangiitis (EGPA). They used medical records to obtain clinical, laboratory and standard spirometry data. Included patients were those who had skin and/or specific IgE testing for common aeroallergens before the vasculitic phase. Findings demonstrated an association of atopy with better prognosis and more severe/uncontrolled asthma manifestations in the year before the development of vasculitis, but not with more severe vasculitis at presentation in patients with EGPA.
