简要总结
The aim of the study was to identify the percentage of patients in whom the diagnosis of current asthma was confirmed or ruled out after clinical, spirometric assessment and utilizing all the possible investigations with a six month follow up period for both groups.
详细描述
The diagnosis of bronchial asthma relies on the existence of characteristic respiratory symptoms which are reversible and variable (diurnal and seasonal) with variable airflow limitation. Unfortunately, bronchial asthma may mimic different pulmonary and non-pulmonary diseases regarding their similar clinical presentations so accurate assessment is required to exclude other possible diagnosis before confirming the diagnosis of bronchial asthma.
There are various phenotypes of asthma as; atopic, non-atopic, and late-onset asthma, which may not be easily diagnosed in the community. Also, asthma may show intermittent versus a relapsing /remitting course, so it is difficult to be diagnosed by a single physician visit. Different studies have found that patients with bronchial asthma were treated empirically without full assessment either to ensure or exclude the asthma diagnosis.
Some symptoms as chest wheezes and breathlessness may be presented commonly in bronchial asthma and other mimic diseases as; chronic obstructive pulmonary disease, bronchiectasis, congestive heart failure, vocal cord disorders, hypersensitivity pneumonitis, endobronchial tumours, pulmonary embolism, aspiration syndromes, tracheal compression by a mediastinal mass and tracheomalacia. So, different physicians should put in mind those asthma mimics to be differentiated from asthmatic patients specially whose asthma symptoms are poorly controlled by anti- asthmatic medications.
