Consensus Review and Definition of Nonallergic Rhinitis With a Focus on Vasomotor Rhinitis, Proposed to Be Known henceforth as Nonallergic Rhinopathy: Introduction to Part 2

"Nonallergic vasomotor rhinitis" (also referred to as nonallergic rhinitis and/or idiopathic rhinitis) is a term that has been used to describe a common nasal condition of unclear pathophysiology. Clinical options for patients are limited by a lack of straight-forward diagnostic criteria and poorly defined and heterogeneous populations in clinical trials. A roundtable conference convened in December 2008 addressed these challenges. Part 1 of the proceedings of that meeting provided a consensus definition of "nonallergic rhinopathy," proposed to replace the former terms above based on the clinical characteristics of the disease, which were described in individual papers. Part 2 of the proceedings uses the revised definition for a consensus discussion on appropriate criteria for enrolling subjects in future clinical studies of the efficacy of potential treatments for this disease.
