Outcome Measures
Primary Outcomes (1)
Total nasal symptom score recorded at baseline, and at pre-challenge,15 mins, 30 mins,and at 1,2,3,4,8 hours
throughout the study
Secondary Outcomes (1)
Peak nasal inspiratory flow at time points of total nasal symptom score. Mechanistic markers during challenge days. Exhaled nitric oxide,forced expiratory vol in 1 second & airway resistance at baseline, first & last day
throughout the study
Interventions
Dust mite extract, Fluticasone, Methacholine
Eligibility Criteria
You may qualify if:
- Healthy non-smoking subjects with a history of allergic rhinitis consistent with dust mite allergy showing
- A positive skin prick test to dust mite at or within the 12 months before study start
- Demonstrate symptomatic worsening after graded nasal allergen challenge
You may not qualify if:
- Subjects found to be very sensitive to house dust mites (if the skin prick test produces a wheal of mean with a diameter greater than 11 mm).
- Presence of any respiratory disease other than a history of mild stable asthma not requiring regular treatment.
- Any known contraindications for methacholine challenge testing
