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

Age18 Years - 55 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

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
