Asthma With Hypersecretion-associated Gene for Cystic Fibrosis (CF-asthma)
Asthma With Hypersecretion-associated Gene for Cystic Fibrosis Clinical, Inflammatory and Genetics Characterization
調査の概要
詳細な説明
Primary objective:
Determine the presence of genetic variants (mutations and / or polymorphisms) of the CFTR gene in patients with asthma with or without bronchial mucus hypersecretion.
Secondary objectives:
To identify genetic variants (mutations and / or polymorphisms) of the most common CFTR gene in the asthmatic population. -To define the inflammatory phenotype of asthma with bronchial mucus hypersecretion. -To compare the severity, control, quality of life and frequency of exacerbations of asthma patients with or without bronchial mucus hypersecretion

50 asthma patients
50 asthma patients with bronchial mucus hypersecretion

Patients with inclusion criteria, following examinations: a study of lung function measurement of the fraction of nitric oxide in exhaled air, induced sputum, sputum, and extraction of peripheral venous blood for Study of genetic variants in the CFTR gene,skin prick test .
The number of eosinophils in peripheral blood by automated cell counting and Total IgE by ELISA were measured.
Furthermore, the level of asthma control be assessed by validated symptom questionnaire Asthma Control Test, quality of life is determined by the MiniAQLQ questionnaire.
