Abstract

Introduction: Identify risk factors for refractory asthma, rapid loss of lung function and irreversible airway obstruction in subjects with asthma contributes to understand the causes and prevent these conditions. Aims: Identify risk factors for refractory asthma, rapid loss of lung function and irreversible airway obstruction in subjects with asthma. Methods: This is a one-year prospective study. Inclusion criteria were asthma diagnosis, age above 10 years old, six months of follow up with a chest physician, three months of regular use of inhaled corticosteroids and sign informed consent. There will be five study visits. V1 is the enrollment visit. The interval between visits will be three months. We will apply questionnaires to measure symptoms control, the characteristics of asthma and environment exposures. Subjects will perform lung function test, and we will collect peripheral blood to count eosinophils and measure total serum IgE. The chest physician will adjust treatment every study visit according to the study protocol. We will perform logistic regression models to identify risk factors for refractory asthma, irreversible airway obstruction and rapid loss of lung function. The status of refractory asthma, irreversible airway obstruction and rapid loss of lung function will be defined according to the condition of the patient in the last study visit. (AU)
