Brief 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.

Interventions

Intranasal capsaicin, 5 applications each delivering 2 micrograms in each nostril, separated by 1 hour.

The nose will be pre-treated with topical lidocaine 15 minutes before each application

Change in Maximum Optical Density Determined Via Optical Rhinometrybaseline, immediately post first treatment on Day 1Optical rhinometry provides continuous measurement of blood flow in nasal vessels (via optical density measurements), which serves as an indirect assessment of nasal congestion. A greater decrease in optical density (OD) from baseline indicates less nasal blood flow and decreased congestion relative to baseline.
Total Nasal Symptom Score as Measured by the Visual Analog Scale (VAS) at BaselinebaselineTotal Nasal Symptom score is measured as the sum of four symptom scores for runny nose, nasal symptoms of congestion, nasal itching and sneezing. Each symptom is scored from 0-10, with 0 being not a problem and 10 being unbearable. The Total nasal symptom score ranges from 0 - 40, the lower the score the better the outcome.

Outcome results

Change in Maximum Optical Density Determined Via Optical Rhinometry

Optical rhinometry provides continuous measurement of blood flow in nasal vessels (via optical density measurements), which serves as an indirect assessment of nasal congestion. A greater decrease in optical density (OD) from baseline indicates less nasal blood flow and decreased congestion relative to baseline.

Time frame: baseline, immediately post first treatment on Day 1

Population: Data were not collected for 6 participants in the treatment arm.
