Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Montelukast

Placebo

Arm Description

Subjects take 1 montelukast 10mg tablet orally, daily and effect on nasal allergen challenge (based on results of epicutaneous skin testing) induced recruitment of cd49d neutrophils in the peripheral blood and nasal lavage determined at 1 week

Subjects take 1 placebo oral pill, daily and effect on nasal allergen challenge (based on results of epicutaneous skin testing) induced recruitment of cd49d neutrophils in the peripheral blood and nasal lavage determined at 1 week.

Outcomes

Primary Outcome Measures

Change in frequency in CD49d+ neutrophils in the nasal lavage post-allergen challenge on placebo versus Montelukast.
The primary outcome will be the change in frequency (as assessed by flow cytometry) in CD49d+ neutrophils in the nasal lavage post-allergen challenge on placebo versus Montelukast.

Secondary Outcome Measures

Change in clinical response following nasal allergen challenge after one week of treatment with Montelukast.
Secondary outcomes will be whether treatment with Montelukast for one week changes the clinical response to nasal allergen challenge (i.e., sneezing, itching, etc.) as documented in the validated Sino Nasal Outcome Test (SNOT)-20 questionnaire.

5. Study Description

Brief Summary
The purpose of this study is to see if the recruitment of a certain cell type (the alpha 4 integrin (CD49d) expressing neutrophil) during a nasal allergen challenge can be inhibited by pretreatment with an FDA approved leukotriene antagonist (montelukast).
Detailed Description
Subjects will be consented, undergo skin testing, medical history questionnaires, and randomized to either placebo or montelukast (10 mg). In one week, subjects return, undergo a blood draw, medical history questionnaires, nasal lavage, and nasal allergen challenge (followed by lavage in 6 hours). Subjects will then cross-over to the other study drug. One week later subjects will undergo a blood draw, medical history questionnaires, lavage, allergen challenge, and repeat lavage (after 6 hours).
