Airway Macrophages and Sputum Milieu in Adult Subjects With Airflow Obstruction

In the United States, a variety of farming operations can generate significant amounts of dust. Chronic organic dust exposure to workers in this industry can result in several respiratory health conditions including chronic bronchitis, chronic obstructive pulmonary disease (COPD), and exacerbations of asthma. Organic dust is a complex mixture containing ...

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 ...

Examining the Genetic Factors That May Cause Chronic Obstructive Pulmonary Disease (COPD)

COPD is a disease in which the lung airways are damaged and partly obstructed, making it difficult to breathe. Millions of people in the United States have COPD, and it is the third leading cause of death in the United States. Symptoms include coughing, excess mucus production, shortness of breath, ...

Phase N/A

Effect of Losartan on Chronic Obstructive Pulmonary Disease (COPD)

Losartan, an angiotensin receptor blocker, has been effective in preventing the development of emphysema and lung inflammation in animal models of COPD. Moreover, there is epidemiologic evidence that suggests that this drug may be effective in reducing COPD morbidity and mortality. This study will provide treatment with either losartan or ...

Study of the Steroid Sparing Effect of Xolair (Omalizumab) in Patients With Persistent Eosinophilic Bronchitis

The purpose of this study is to investigate whether addition of Omalizumab enables a reduction in the dose of prednisone in patients with asthma and eosinophilic bronchitis. This will be a double-blind placebo-controlled, 3-centre, randomized parallel group trial divided into two sequential study periods. Period 1: After establishing the minimum ...
