Inhaled Corticosteroid Withdrawal in Chronic Obstructive Pulmonary Disease (COPD)
The Clinical Effect of Inhaled Corticosteroid Withdrawal in Chronic Obstructive Pulmonary Disease (COPD) Patients
According to the WISDOM study, withdraw of inhaled steroids has no effect on the acute exacerbation of chronic obstructive pulmonary disease (COPD), but the lung function of patients with COPD is significantly reclined. In the subgroup analysis of this study, patients with COPD were found to have continued to use inhaled steroids in patients with eosinophilic leukocytes greater than 400 cells/ul or whom has more than two episodes of exacerbation per year. However, in SUNSET study, it was pointed out that withdraw of inhaled steroids had no effect on lung function in patients with COPD, but it was also found that in patients with COPD, eosinophilic leukocytes in the blood were greater than 300 cells/ul, have a better therapeutic response in steroid inhalation. In addition, some studies have shown that in patients with COPD, a decline in lung function after discontinuation of inhaled steroids can make the patient's clinical symptoms worse and increase the risk of acute exacerbations. However, in other comprehensive analytical studies, there are different outcomes. There is no statistically significant difference in the risk of acute exacerbation in patients with COPD after discontinuation of inhaled steroids.
In past studies, it was noted that inhaled steroids cause an increased risk of pneumonia in patients with COPD. However, in these studies, the diagnosis of pneumonia was only from the clinician's suspicion without clear symptom assessment, laboratory examination, microbiological evidence or imaging assessment. Therefore, further research is needed to assess whether patients are suitable for the reduction of inhaled steroids and the impact of COPD in clinical treatment.

COPD Assessment Test (CAT) score
Time Frame: 6 months

Modified Medical Research Council (mMRC) Dyspnea Scale
Time Frame: 6 months
|
Modified Medical Research Council (mMRC) Dyspnea Scale is consisting of just five items containing statements about the impact of breathlessness on the individual and leading to a grade from 1 to 5. (1.
Not troubled by breathless except on strenuous exercise; 2. Short of breath when hurrying on a level or when walking up a slight hill; 3. Walks slower than most people on the level, stops after a mile or so, or stops after 15 min walking at own pace; 4. Stops for breath after walking 100 yards, or after a few minutes on level ground; 5. Too breathless to leave the house, or breathless when dressing/undressing).
