Laminar Airflow in Severe Asthma for Exacerbation Reduction - 48 Month Follow-up.

Asthma affects over 5.4 million people in the UK with nearly 500,00 experiencing severe symptoms and frequent exacerbations that are inadequately controlled with available treatments. The burden of severe asthma on the NHS is enormous accounting for 80% of total asthma cost. In 2009 there were 1131 deaths due to ...

Phase N/A

Childhood Asthma Management in Primary Care: Implementation Of Exhaled Nitric Oxide and Spirometry Testing

What are the capacity and training needs in general practice to implement routine spirometry and eNO testing in children aged 5-16 years? Asthma is the commonest long-term disease of childhood in the United Kingdom (UK). Under-diagnosis and under-treatment of childhood asthma in general practice (GP) have been reported from several ...

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

Role of Genetic Factors in the Development of Lung Disease

This study is designed to evaluate genetic mechanisms of lung disease by surveying polymorphic genes involved in respiratory function and examining gene expression in the lung cells of individuals with pulmonary disease (e.g., alpha 1-antitrypsin deficiency, asthma, chronic obstructive pulmonary disease, cystic fibrosis, sarcoidosis, history of infection, and genetic mutations ...

Phase N/A

Segmental Bronchoalveolar Lavage

This protocol proposes to perform bronchoalveolar lavage, bronchial brushing and bronchial wall biopsy in research volunteers and in patients with pulmonary disease to evaluate the cellular components of normal and diseased lungs. This research study will help to improve our understanding of pathogenic mechanisms in the lung during progression of ...

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

Longitudinal Observational Study of Severe Asthma

Asthma is a common disease and a significant public health problem, affecting one in every 10 individuals, nearly 30 million people in the US alone. About 5-10% of asthmatics have severe disease that is difficult to control with standard therapies. Severe asthmatics are considered to be relatively resistant to corticosteroids, ...

Phase N/A

Analysis of Inflammation and Microbiome in Patients With Sinusitis and Asthma

This is a cross-sectional and non-interventional study to investigate mechanisms of disease in patients with asthma who have concomitant chronic sinusitis and/or nasal polyps (upper airway disease). Approximately 160 participants will be enrolled. Patients who are scheduled to undergo inpatient or outpatient endoscopic sinus surgery at the University of California ...

Phase N/A

Gene Expression Profile and Inflammation Profile of Classic Asthma Cough Variant Asthma and Eosinophilic Bronchitis

Asthma is a common and heterogeneous respiratory disorder affecting millions of people, posing a considerable burden on health care systems globally. The disease is characterized by inflammation of the airways with eosinophils, neutrophils, mast cells, lymphocytes, airway epithelial cells, smooth muscle cells and other cells, by airflow obstruction and by ...

Phase N/A

Asthma Origins and Remission Study

Rationale: Asthma inception occurs only in susceptible individuals, and is often triggered by specific environmental factors, such as respiratory viruses and aeroallergens. Although asthma is generally viewed as a chronic persistent disease, remission of asthma is possible in a subset of patients. This is highly relevant, since understanding mechanisms that ...
