Atopy patch test in normal population

Condition Intervention Phase
Device: Atopy patch test with food allergen
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Atopy Patch Test in Normal Population : Pilot Study

Further study details as provided by Mahidol University:

Primary Outcome Measures:
  • Reaction of atopy patch test [ Time Frame: 3 days ]
    To evaluate outcome of atopy patch test reaction in non-atopic subject

Secondary Outcome Measures:
  • Comparisons atopy patch test reaction between lyophilized allergen and commercial allergen [ Time Frame: 3 days ]
    To compare outcome of atopy patch test reaction using lyophilized allergen and commercial allergen

Enrollment: 15
Study Start Date: February 2010
Study Completion Date: May 2010
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Atopy patch test
Atopy patches were applied on healthy volunteer's back for 48 hrs then the patches were removed. Reaction was evaluated 48 and 72 hrs after applying atopy patch test
Device: Atopy patch test with food allergen
Atopy patches used with food lyophilized allergen and commercial allergen were placed on back of subjects for 48 hrs then atopy patches were taken off. Subjects should return to evaluate reaction one day later(72 hrs after applying atopy patch test)

Detailed Description:
The initial diagnostic work up of suspected food allergy includes patient's history, skin prick test (SPT), measurement of food specific immunoglobulin E (IgE) with serological assays, and more recently the atopy patch test. A positive SPT seems to reflect early reactions to food challenges, whereas the atopy patch test has a high diagnostic efficacy for late phase clinical reactions. The purpose of this study was to evaluate atopy patch test reaction in non-atopic population.
