The Prevalence and Clinical Characteristics of Children With Local Allergic Rhinitis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02271620
Recruitment Status : Completed
First Posted : October 22, 2014
Last Update Posted : March 22, 2018
Information provided by (Responsible Party):
Orathai Piboonpocanun, Mahidol University

Brief Summary:
  • To determine prevalence of local allergic rhinitis (LAR)
  • To evaluate clinical characteristic and severity of local allergic rhinitis
  • To measure changing of tryptase and Specific IgE for Dermatophagoides pteronyssinus (Dp) after nasal allergen provocation test (NAPT)

Condition or disease Intervention/treatment Phase
Other Allergic Rhinitis Procedure: nasal allergen provocation test Not Applicable

Detailed Description:
Children 8-18 years with NAR were recruited. A NAPT with Der p 1 solutions (NAPT-DP) at 200 AU/mL, 600 AU/mL and 2000 AU/mL at 15-minute interval was performed, respectively. The immediate responses to NAPT-DP were assessed using symptoms score, peak nasal inspiratory flow (PNIF) and acoustic rhinometry (ARM). The nasal tryptase and sIgE-DP were measured at baseline, 15 min and 1 h after positive NAPT-DP. Allergic rhinitis (AR) patients were used as positive control.
