Nasal Physiologic Reactivity of Nonallergic Rhinitics to Cold Air Provocation

Associated Scientists to Help Minimize Allergies·interventional·Posted Dec 25, 2006·Updated Mar 6, 2017

In Brief

A clinical study evaluating Cold-dry air provocation and Warm-moist air provocation for Vasomotor Rhinitis. Completed, enrolled 24 participants across 1 site.

Detailed Summary

This study seeks to compare patients with vasomotor rhinitis ("perennial nonallergic rhinitis," "idiopathic rhinitis") with normal controls with respect to their nasal physiologic reactivity to cold air challenge. Ten vasomotor rhinitis (VMR) patients with nasal symptoms triggered predominantly by cold air, four VMR patients with symptoms triggered predominantly by chemicals, and ten nonallergic, non-rhinitic control subjects will be studied.
