  Purpose

The purpose of this study is to evaluate development of allergic rhinitis in children with nonallergic rhinitis.


Condition Intervention
Allergic Rhinitis (Disorder)
 Procedure: skin prick test

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Cross-Sectional
Official Title: The Development of Allergic Rhinitis in Children Previously Diagnosed as Nonallergic Rhinitis

Further study details as provided by Mahidol University:

Primary Outcome Measures:
  • To evaluate the development of AR in children who were previously diagnosed with NAR [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To determine the persistence and severity of the symptoms, new comorbidities and triggering factors in children with nonallergic rhinitis [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]

Enrollment: 175
Study Start Date: January 2010
Study Completion Date: August 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Nonallergic rhinitis
Nonallergic rhinitis (negative skin prick test)
 Procedure: skin prick test
skin prick test to aeroallergen
Other Name: SPT

Detailed Description:

Rhinitis is a common condition associated with significant effects on quality of life. Rhinitis may be divided into two groups, those with concurrent allergy (allergic rhinitis, AR) and those without allergy but who still suffer from nasal symptoms (nonallergic rhinitis, NAR).

Evidence indicated that adult with NAR can have de novo sensitization to aeroallergen (24%), suggesting that patients with NAR might evolve to AR. Thus the purpose of this study is to evaluate development of allergic rhinitis in children with nonallergic rhinitis.
