Lung Disease Clinical Trial
Official title:
Exhaled Breath Condensate and Nitric Oxide: Non-invasive Evaluation of Lung Disease After Treatment With Xolair
The purpose of this study is to study the effects of Xolair using non-invasive techniques from the expired gas of patients with moderate to severe allergic asthma.
Traditional methods of sampling secretions from the lower respiratory tract include sputum collection, sputum induction, and bronchoscopy with bronchoalveolar lavage. They cannot be repeated within a short period of time because of their invasiveness, and because the procedures themselves may include an inflammatory response. The need to monitor inflammation in the lungs has led to the exploration of exhaled gases and condensates. Noninvasive monitoring may assist in differential diagnosis of pulmonary diseases, assessment of disease severity and response to treatment. ;
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
