To observe prospectively the changes in various markers following a dose reduction in budesonide/formoterol combination drug (Symbicort Turbuhaler) in patients with bronchial asthma who received treatment with budesonide/formoterol (4 inhalations/day) for at least 3 months and whose symptoms during this period were controlled according to the GINA classification.
Others
Using sputum eosinophil count as the standard marker of airway inflammation, to screen easy-to-measure biomarkers whose levels change in parallel to those of the standard marker and to identify biomarkers which can predict, prior to a dose reduction, those patients whose airway inflammation is likely to be aggravated by the change.
1) Patients are classified into those who show aggravation of airway inflammation and those who do not after a dose reduction. A multivariate analysis is performed to identify the factors and parameters which account for the aggravation and increased eosinophil ratio (reflecting aggravation of airway inflammation) by evaluating patient demography prior to the dose reduction, absolute values of various parameters determined, and combinations thereof.
2) The correlation of sputum eosinophil count with FeNO level, ACQ score or GINA classification in asthma control is investigated.

Not applicable |
Male and Female
1. Patients with bronchial asthma who are at least 18 years of age at the time of consent
2. Patients who are able to understand the details of the study and who, at their own will, give written consent to participate in the study.
3. Patients, who in the opinion of the investigator, can comply with adherence to treatment, keep a patient diary, and perform peak flow measurements (morning and night) during the study period.
4. Patients who have continuously received given budesonide/formoterol (4 inhalations/day; BUD/FOR 640/18 mcg/day) therapy for at least the preceding 3 months
5. Patients with controlled asthma, as defined by the GINA classification, for at least the preceding 3 months. It should be noted that the control level at the commencement of the observation period may be assessed subjectively by the investigator as materials such as the patient diary may not always be available. In this study, the normal range for respiratory function was defined as any of the following:
1) %FEV1 >= 80%
2) FEV1 is >= 80% of personal best
3) Morning PEF is >= 80% of normal predicted value (in 1 week)
4) Morning PEF is >= 80% of personal best (in 1 week)
6. Patients whose ACQ5 score (survey regarding asthma management) is <= 0.75
1. Smoking history: >= 10 packs/yr
2. Current smokers (including patients who quit smoking < 1mth)
3. Patients with any of the following lung diseases:
COPD, bronchiectasis, lung cancer, collagen disease, pulmonary hypertension, tuberculosis sequelae, diffuse panbronchiolitis, interstitial pneumonia
4. Patients who were hospitalized due to asthma in the past year, who had an emergency presentation of asthma in the past 3 months, or who received an infusion of steroids due to worsening of asthma in the past 3 months.
5.Other patients judged by the physician to be inappropriate for this study
