Patients
A = Patients with allergic rhinitis sensitized to dust mites
|
TPNC to dust mite has an interest in the diagnosis of allergic rhinitis to dust mites when there remains a doubt due to the poly sensitization of the patient, or the lack of specific symptoms and / or the variability of the allergic symptoms during the year.
However, this test has not completely validated with a study including a significant number of patients.
That's why we plan a prospective single-center comparative open study with the main objective is to determine the sensitivity and specificity of conventional nasal provocation test (TPNC) in 120 patients of 18 to 65 years old with allergic rhinitis sensitized to dust mites and patients with allergic rhinitis not sensitized to dust mites.
Our secondary objective is to compare the TPNC a faster TPN-called "minute" (60 minutes) and which allow a wider use.
If we demonstrate the validity of TPN then it would become the gold standard needed to decide on a desensitisation to mites.
