|Official Title:||Inflammatory, Functional and Image Composite Measure to Define Asthma Control|
- Asthma control status characterized by nocturnal and diurnal symptom score FEV1,total lung capacity in plethysmography and reducing the air-tapping in HRCT. [ Time Frame: 30 days ]
- Quality of life, Sputum and nasal cytology, adverse events [ Time Frame: 30 days ]

To evaluate the achievement of asthma control status in asthmatic patients, regularly treated with IC + LABA to answer the following questions:
i. Is it possible to improve the pulmonary function (spirometry and plethysmography) of stable asthma patients, regularly treated with IC + LABA, who have a positive bronchodilator response, with the introduction of oral steroid?
ii. What is the relationship among nasal, induced sputum and blood cytology, as a tool to observe inflammatory airway expression, in controlled and total controlled asthma patients? What will be these values response if oral steroids have been introduced?
iii. What is the correlation between pulmonary volumes and airways inflammation to evaluate severity and control status in asthmatic patients, using plethysmography and HRCT? What will be these values response if oral steroids have been introduced?
