Nasal allergen provocation test in nasal polyposis with and without allergy
Methods Four groups of patients (n=48) underwent nasal allergen provocation test for grass pollen. We included 12 patients with allergic rhinitis based on grass allergy, 12 patients with CRSwNP without grass allergy, 12 patients with CRSwNP with grass allergy, and 12 control patients. The diagnosis of grass allergy was based on skin prick test and RAST. The test was positive based on change in ...
متن کاملDynamic Changes in Heart Rate Variability and Nasal Airflow Resistance during Nasal Allergen Provocation Test
Allergic rhinitis is a major chronic respiratory disease and an immunoneuronal disorder. We aimed at providing further knowledge on the function of the neural system in nasal allergic reaction. Here, a method to assess simultaneously the nasal airflow resistance and the underlying function of autonomic nervous system (ANS) is presented and used during the nasal provocation of allergic and nonal...
متن کاملNasal polyposis, eosinophil dominated inflammation, and allergy.
A polyp is an oedematous mucous membrane which forms a pedunculating process with a slim or broad stalk or base. Nasal polyps originate in the upper part of the nose around the openings to the ethmoidal sinuses. The polyps extend into the nasal cavity from the middle meatus, resulting in nasal blockage and restricted airflow to the olfactory region. The polyp stroma is highly oedematous with a ...
متن کاملLocal and systemic effects of cat allergen nasal provocation.
BACKGROUND Cat allergen is widely distributed in homes and schools; allergic sensitization is common. OBJECTIVE To develop a model of cat allergen nasal challenge to establish dose-response and time-course characteristics and investigate local and systemic biomarkers of allergic inflammation. METHODS Nineteen cat-allergic individuals underwent titrated nasal challenge, range 0.243 to 14.6 μ...

Although patients with rhinitis are frequently sensitised to foods, there is little evidence to support the role of food allergy in causing rhinitis in isolation. The presence of food allergy in infants may be a marker for subsequent development of allergic rhinitis. While many patients associate the ingestion of cow’s milk with an i...
