TGF-(Beta) and Susceptibility to RSV

This is a cross-sectional, controlled study designed to investigate whether Transforming Growth Factor-beta (TGF-beta) mediates increased asthmatic epithelial susceptibility to respiratory syncytial virus (RSV) infection by examining responses to RSV infection in epithelial cells cultured from asthmatic and non-asthmatic participants. Non-smoking healthy adults and mild asthmatics, aged 18-60 years old, …

Phase N/A

The Dallas Asthma Brain and Cognition (ABC) Study

This study will implement a cross-sectional design, conducted across two sessions. The first session will capture cognitive performance, health history, and relevant social, behavioral, and emotional processes. The second session approximately one week later will capture neural structure, function, and chemistry. In the first session, participants will undergo screening for …

Phase N/A

A Study to Assess the Efficacy and Safety of Budesonide/Albuterol Metered-dose Inhaler (BDA MDI/PT027) Used 4 Times Daily in Adults and Children 4 Years of Age or Older With Asthma

This is a randomized, double-blind, placebo-controlled, multicenter, parallel group study to compare 2 dose levels of BDA MDI (PT027) to its components BD MDI (PT008) and AS MDI (PT007) on improvement in lung function and asthma symptoms after 12 weeks of treatment in adult, adolescent, and child subjects with symptomatic …


Bronchial Thermoplasty for Severe Asthma With Dynamic Hyperinflation

Bronchial thermoplasty is a recently validated bronchoscopic technique for the management of severe asthma that treats smooth muscle by radiofrequency to reduce its thickness. This procedure leads to improved asthma control and quality of life, but also to decreased exacerbations frequency and number of emergencies hospitalizations. This treatment requires 3 …

Phase N/A

Mechanism(s) of Airflow Limitation During Exacerbation of Asthma

In addition we will also obtain above studies in asthmatics during naturally occuring exacerbation of asthma and following treatment. If available, results of lung function studies including measurements of lung elastic recoil will be compared to pathologic analyses of formalin fixed, air inflated lungs obtained at autopsy in asthmatics who …


Effectiveness and Implementation of the Assessment of Burden of Chronic Conditions (ABCC)-Tool

This study is designed to evaluate the effectiveness and implementation of the Assessment of Burden of Chronic Conditions (ABCC)-tool for patients with COPD, asthma, diabetes mellitus type 2 or heart failure (and any combination of these conditions) in real-life routine practice. The ABCC-tool consists of a questionnaire, a visualisation using …

Phase N/A

Activation and Function of Eosinophils in Conditions With Blood or Tissue Eosinophilia

Subjects admitted on this protocol will have elevated eosinophil counts in the peripheral blood or tissues or will be relatives of subjects with eosinophilia. Eosinophilic subjects will undergo an extensive clinical evaluation focused on the identification of the cause of eosinophilia and the presence of end organ manifestations. In addition, …

Phase N/A

Sample Collections From the Airways of Asthmatic Patients

This tissue procurement protocol proposes to perform bronchoscopy with bronchoalveolar lavage, bronchial brushings, and bronchial wall biopsies as well as to collect samples of sputum, exhaled breath condensates and blood, in order to evaluate the molecular mechanisms underlying the pathogenesis of airway inflammation, airway hyperresponsiveness, and airway remodeling in asthmatic …

Phase N/A

Pulmonary Condensate: Non-invasive Evaluation of Pulmonary Involvement in Asthma and Cystic Fibrosis.

Exhaled breath condensate (EBC) represents a rich source for countless biomarkers that can provide valuable information about respiratory as well as systemic diseases. Finding non-invasive methods for early detection of lung injury, inflammation and infectious complications in chronic diseases like Cystic fibrosis (CF) or Bronchial asthma (AB) would be highly …

Phase N/A

Increased Lung Volume as Controller Therapy for Asthma

The effect of 10 versus 0 cmH2O CPAP on airways responsiveness to inhaled methacholine will be studied using an adaptive "3+3" phase I/II study design. Dose Titration Phase (phase I): The efficacy of 8 hours of CPAP on airway responsiveness will be tested in three subjects. Efficacy will be defined …
