Filter by:Patients with chronic obstructive pulmonary disease (COPD) that have frequent chest infections are the patients most likely to become worse over time. Why these people are more susceptible to chest infections is not known. One reason might be that the white cells in their lungs called macrophages do not work properly. Normally, these cells remove all the debris inhaled into the lung. This can also include bacteria. In patients with COPD, these macrophages are not able to remove these particles. The research question addresses why this happens
The purpose of this study is to evaluate the safety and effectiveness of levofloxacin, an antibiotic, compared with cefuroxime axetil, another antibiotic, in the treatment of adults with chronic bronchitis experiencing rapid onset of worsening of symptoms caused by bacteria.
This study evaluates the safety of medicine on COPD (Chronic Obstructive Pulmonary Disease). This study will last up to 56 weeks, and subjects will visit the clinic 16 times. Subjects will be given breathing tests, and will record their breathing symptoms daily on diary cards.
The purpose of this study is to evaluate the safety and effectiveness of levofloxacin, an antibiotic, compared with cefaclor, another antibiotic, in the treatment of adults with chronic bronchitis experiencing rapid onset of worsening of symptoms caused by bacteria.
This trial is a research drug study to compare the effects of two antibiotics for the treatment of acute exacerbation of chronic bronchitis
To evaluate the long-term safety and monitor the long-term efficacy of arformoterol over a period of 6 months in subjects with chronic obstructive pulmonary disease (COPD).
A study to report the outcomes of patients who fail to respond to beta-lactam and macrolide antibiotics in the community
The purpose of this protocol is to obtain biologic materials from the blood and lungs from patients with lung disease in order to develop an understanding of the etiology and pathogenesis of these disorders. General admission criteria for this project will require at least one of the following: (1) symptoms consistent with pulmonary disease; (2) chest X-ray consistent with lung disease; (3) pulmonary function tests consistent with lung disease; (4) lung biopsy consistent with lung disease; (5) family history of lung disease; and (6) patients with diseases of organs with known association with lung disease.
This is a randonmized, masked, placebo-controlled parallel group, clinical trial to evaluate the effects of three different doses of N-acetyl L-cysteine (NAC) and placebo on patient safety and on physical and transport properties of expectorated sputum. Patient sumptoms, quality of life and exacerbation will also be followed as well as pulmonary function testing and functional exercise capacity. We hypothesized that a prolongeed course of oral NAC favorably affects the morbidity of chronic bronchitis, particularly the incidence of acute exacerbations.
The aim of this family practice based study is to determine the long-term treatment effects of two drugs that are presumed to modify the course and progression of chronic obstructive pulmonary disease (COPD), oral N-acetylcysteine and inhaled corticosteroids.
