The Prevalence of Local Immunoglobulin E (IgE) Elevation and Its Effect on Intranasal Capsaicin Therapy in the Non-allergic Rhinitis Population

Summary

The purpose of this study to determine the therapeutic response of non-allergic rhinitis patients that have been subtyped as non-allergic rhinitis with local IgE elevation or non-allergic rhinopathy to intranasal capsaicin based on visual analog scale and optical rhinometry, to determine the prevalence of non-allergic rhinitis with local IgE elevation in this study's cohort of patients with non-allergic rhinitis identified by rhinitis history and negative skin testing for allergic rhinitis, and to determine the change, if any, in intranasal IgE levels after capsaicin treatment.
