Brief Summary
Smoking occurs frequently in patients with asthma. Recent surveys on smoking prevalence report 21-26% current smokers in populations of patients with asthma. Detrimental effects of active smoking in asthma include worse asthma control, an impaired response to corticosteroids and accelerated lung function decline.

Serum eotaxin-2
detect its level in serum
One day
Secondary Outcomes (3)

Study Arms (2)
smoker asthmatics
* Asthma control questionnaire (ACQ) score * Spirometry * Sputum cytology
non-smoker asthmatics
* Asthma control questionnaire (ACQ) score * Spirometry * Sputum cytology
Interventions
collect serum sample from each group and detection of serum periostin and eotaxin-2 are using Eliza kits. each group is divided into two groups (patients who are already using ICS and patients who do not use ICS) and we compare between to groups in airway hypersensitivity.
each group is divided into two groups (patients who are already using inhaled corticosteroid ICS and patients who do not use ICS) and we compare between to groups in airway hypersensitivity.
Eligibility Criteria
Stable asthmatic patients (however smokers, or non-smokers) will be included (stable asthmatic defined as no emergency clinic or hospital visit, oral corticosteroid prescription, or change in asthma treatment in the past month) and (Current smoking was defined as 5 or more cigarettes per day and a smoking history of 5 pack years or greater).
You may qualify if:
- Stable asthmatic patients (however smokers, or non-smokers) will be included (stable asthmatic defined as no emergency clinic or hospital visit, oral corticosteroid prescription, or change in asthma treatment in the past month) and (Current smoking was defined as 5 or more cigarettes per day and a smoking history of 5 pack years or greater).
- Treatment with long-acting b2-agonists, and leukotriene receptor antagonists was allowed.
You may not qualify if:
- Acute severe asthma.
- Causes of airway obstruction other than asthma as COPD patients, bronchiectasis……etc.
- Age \<18 and \>45 years old.
- Body mass index \>35.
- Requirement for treatment with or the presence of conditions likely to be exacerbated by oral corticosteroids
- The intention to stop smoking. Eligibility for the study required demonstration of reversible airflow obstruction (FEV1 bronchodilator response to b2 agonist of \>12% \[and \>200 mL\]) or a positive methacholine test result. All lung function assessments met relevant international consensus guidelines.
