Clinical Trial Summary

The primary objective of this study is to determine if broccoli sprouts (BS) improves nasal inflammatory, oxidative stress (OS), and symptom responses to nasal mouse allergen challenge (NAC) in mouse-sensitized adults perennial allergic rhinitis.

The study is a double-blind, placebo-controlled, randomized trial to compare BS to placebo in 24 mouse-sensitized adults with asthma or perennial rhinitis and who develop rhinitis symptoms with nasal mouse allergen challenge. Twenty-four adults (age 18-50) who meet these eligibility criteria will be randomized to receive either: (a) BS or (b) placebo. At the baseline NAC, FENO, FEV1, nasal epithelial gene expression, urinary OS biomarkers, serum inflammatory and OS biomarkers, basophil activation, and symptoms will be assessed both before and after NAC to establish pre-intervention responses to NAC. Subjects will eat a sprouts sandwich daily for three days, and then undergo repeat NAC that includes measurement of the above outcomes both before and after NAC.
