Immediate Hypersensitivity Clinical Trial
Official title:
In-vivo Potency Evaluation of American Cockroach, Dog, Cat, Dust Mites and Mold Allergen Extracts Produced by Siriraj Hospital Comparing With Imported Extracts by Using Skin Prick Test.
The prevalence of Allergic rhinitis(AR) and asthma was increased world wide. In 1998, ISAAC
found that prevalence of AR and asthma inThailand was in moderately high group.
Tests for immediated reaction SPT and spIgE, were used for evaluated sensitization of
allergen in patient. They guided the investigators for proper management as well as patient
education. Clinician will use the result for choose allergen in case that might need
immunotherapy.
SPT is safe and more economic for patient. Specific IgE has an advantage in patient who
cannot withhold antihistamine prior SPT. In United state had a trial of result between SPT
and spIgE for cockroach, cat, house dust mite and mold. It showed the correlation between
two tests. In Thailand, the investigators haven't had data about it yet.
SPT and specific IgE for allergens is necessary for allergen avoidance and specific immunotherapy. To have local allergen extracts will help the patients to easier get the appropriate management ;
